Working Principle of Pneumatic Knocker:
When no compressed air (above 3Kg/cm) is supplied to the Pneumatic Knocker, the magnetic piston is tightly attached to the fixed base plate by strong magnetic force.When the three-way solenoid valve is energized, compressed air flows into the main body of the Pneumatic Knocker, and the pressure inside the main body increases. When the pressure exceeds the magnetic force, the magnetic piston detaches from the base plate at high speed, and a strong counterforce is generated due to the reaction force of the strong magnetic force.The magnetic piston falling at high speed hits the base plate, and its impact force is transmitted to the silo, knocking off the attached powder with strong impact force.When the three-way solenoid valve is de-energized, the compressed air inside the Pneumatic Knocker main body is discharged through the three-way solenoid valve. Then, the magnetic piston is slowly lifted up by the return spring to approach the base plate again, and is tightly connected to the base plate by magnetic force to return to the initial state.There is a strong magnetic magnet inside the hammer head. Before operation, the magnetic hammer head is tightly attached to the magnetic base plate. When the three-way solenoid valve is energized and the inlet pressure exceeds the attaching magnetic force, the magnetic hammer head detaches from the base plate at high speed and impacts the bottom. After the impact, the three-way solenoid valve is de-energized, the gas inside the product is discharged, and the hammer head resets.The impact force of the Air Knocker is transmitted to the pipeline or silo wall, ensuring the smooth flow of materials.It is widely used in chemical, fertilizer, pesticide, cement, fuel and other powder processing industries.
Precautions for Pneumatic Knocker:
- The air source must be clean, because contaminated air will accelerate the wear of the piston seal, cause seal failure, and also have a great impact on the service life of the two-position three-way solenoid directional valve.
- The bottom of the Air Knocker must be firmly welded to the silo wall, and the connection between the Air Knocker and the Air Knocker base must be tight. Otherwise, it will loosen or even fall off after a period of knocking, so it is necessary to regularly check whether the Air Knocker is firmly installed.
- The adjustment of the Air Knocker controller varies depending on the model and installation conditions of the Air Knocker. For unclear issues, please consult our company.
- When welding the Air Knocker base, if the silo wall is too thin, please consider adding a reinforcing plate between the Air Knocker base and the silo wall.
- After safely using the product for two months, it is recommended to disassemble it and add grease to extend its service life.

Scraper Arch Breaker
- High-Quality Material Guarantee: The main body is made of SUS304 stainless steel, which has stable physical properties. It is not only corrosion-resistant and wear-resistant but also meets the hygiene level requirements of the food and pharmaceutical industries, avoiding contamination when materials come into contact with the equipment. SUS304 stainless steel scraper arch breakers are safe for food-grade applications.
- Simple Structural Design: The overall structure has no complex redundant parts and adopts a "bolt-free" assembly process, reducing gaps for material accumulation and cleaning blind spots. During daily maintenance, there is no need to disassemble complex components; only the scraper wear condition and gear lubrication status need to be checked, which greatly reduces maintenance costs and downtime. Low-maintenance scraper arch breakers save production costs for factories.
- Long Service Life: The core transmission components (gears) adopt precision machining technology, and combined with the wear-resistant treatment of the scraper, mechanical loss during operation is reduced. At the same time, compared with chain transmission, the gear transmission method avoids the risk of chain loosening and breaking, and the average service life of the equipment is more than 30% longer than that of traditional discharging equipment. Long-life scraper arch breakers reduce equipment replacement frequency for manufacturers.
- Significant Arch-Breaking and Wall-Cleaning Effect: The design of the scraper making circular motion along the silo wall can directly act on the retained materials on the side walls and bottom of the silo. It not only solves the "bridging" and "hollowing" problems but also cleans the materials attached to the silo wall, avoiding caking and deterioration caused by long-term material retention and improving material utilization rate. Scraper arch breakers with excellent wall-cleaning function enhance production efficiency.
- Alleviating Material Segregation: For mixed materials with uneven particle sizes, traditional discharging methods are prone to "segregation" (large particles concentrate at the bottom and small particles concentrate at the top) due to different particle settlement speeds, which affects subsequent production quality. The scraper arch breaker keeps the materials in a mixed state during the falling process through the uniform stirring and pushing of the scraper, effectively alleviating the segregation problem. Scraper arch breakers prevent material segregation for consistent product quality.
- Quiet Operation Experience: The gear transmission link adopts a high-precision meshing design, and combined with the lubrication treatment of bearings, the noise during operation is controlled below 60 decibels (equivalent to the volume of daily conversation), avoiding the harsh noise of traditional discharging equipment during operation and improving the workshop working environment. Quiet scraper arch breakers create a comfortable working environment for production line engineers.
- Wide Hopper Angle Adaptability: It can adapt to hopper angles within 45°. Whether it is a vertical silo or an inclined silo, accurate connection can be achieved by adjusting the installation angle, without the need for large-scale modification of the existing silo structure. Scraper arch breakers with flexible hopper angle adaptation fit various silo types.
- Rich Specifications and Customization Options: Standard caliber specifications from φ40 to φ500 are provided, covering different needs from small laboratory equipment to large-scale industrial production lines. For large-caliber needs beyond the standard caliber (such as above φ500), exclusive equipment can be customized through technical consultation according to the customer's silo size and material characteristics, ensuring seamless connection with the existing production system. Customizable scraper arch breakers meet diverse industrial needs for purchasers.
- Expandable Blade Design: It supports the installation of multiple scraper blades (the specific number is determined according to material fluidity and discharging volume). The more blades there are, the higher the discharging efficiency and the more uniform the material stirring, which can be flexibly adjusted according to the actual production rhythm. Expandable blade scraper arch breakers optimize discharging efficiency for different production beats.
KCB Series Gear Pump
- KCB Series Gear Pump is mainly composed of gears, shafts, pump body, relief valve and shaft end seal. The gears undergo heat treatment to achieve high hardness and strength, and are installed in replaceable shaft sleeves together with the shafts for operation. The lubrication of all parts in the KCB Series Gear Pump is automatically achieved by using the output medium when the pump is working.
- The pump is designed with reasonable oil discharge and oil return grooves, which reduce the torque force borne by the gears during operation. As a result, the bearing load is small, wear is minimal, and the KCB gear oil pump has high efficiency.
- KCB Gear Pump is equipped with a relief valve for overload protection. The full return pressure of the relief valve is 1.5 times the rated discharge pressure of the pump. The KCB gear oil pump can also be adjusted separately according to actual needs within the allowable discharge pressure range. However, it should be noted that this relief valve cannot work as a pressure reducing valve for a long time; if necessary, a separate pressure reducing valve can be installed on the pipeline. When viewing the pump from the extended end of the main shaft, the rotation direction is clockwise.
Knife Gate Valve
- Ultra-short structural length saves materials and greatly reduces the overall weight of the pipeline system matched with the knife gate valve.
- It occupies small effective space, effectively supports pipeline strength, and reduces the possibility of pipeline vibration when used with the knife gate valve.
- The gate plate of the knife gate valve is made of austenitic stainless steel, which greatly improves corrosion resistance and effectively prevents sealing leakage caused by gate plate corrosion.
- The upper sealing packing of the knife gate valve adopts flexible PTFE, ensuring reliable sealing and easy, flexible operation.
- The gate plate of the knife gate valve has a knife function, which can effectively cut off various impurities in the medium.
