The material column is high, the potential energy is large, the pressure is large, the conveying capacity is correspondingly large, and otherwise, the conveying capacity is small. The air material mixer keeps a certain material level height when working normally, the material level height naturally rises when the blanking amount of the material bin is increased in a short time and the air material mixer still works normally, the potential energy is increased along with the increase of the material level height, the conveying amount is correspondingly large until the system is automatically balanced, the blanking amount of the material bin is reduced in a short time and the air material mixer still works normally, the material level height naturally reduces, the potential energy is reduced along with the reduction of the material level height, and the conveying amount is correspondingly small until the system is automatically balanced.

Upper mounting plate and cyclone device
Mounting a mounting plate: the magnetic frame is formed by processing a steel plate, is welded on the cyclone dust collector, and is matched with a processing spigot of the magnetic frame.
A cyclone separator is a device that uses the action of inertial centrifugal force to separate material from a gas stream. The upper part of the main body is cylindrical, and the lower part of the main body is conical. The gas containing material enters tangentially from the gas inlet pipe at the upper part of the cylinder and is constrained by the wall of the cylinder to make a downward spiral motion. Under the action of inertial centrifugal force, the particles are thrown to the wall of the device to be separated from the airflow and then fall to the discharge opening of the cone bottom along the wall surface. The purified gas spirally moves from bottom to top near the central shaft and is finally discharged from the top exhaust pipe. Generally, the downward spiral flow is called an outer vortex, and the upward spiral flow is called an inner vortex (also called an air core). The rotating directions of the inner swirling air and the outer swirling air are the same. The upper part of the outer cyclone is the main separation zone. The static pressure in the cyclone is highest near the wall and only slightly lower than the pressure at the gas inlet, decreasing towards the centre and falling below the gas outlet pressure at the gas core. The low-pressure gas core in the cyclone separator extends to the bottom ash outlet from the first exhaust pipe inlet. Therefore, if the discharge port or the material collecting chamber is not sealed well, gas is easy to leak, dust collected at the bottom of the cone is rewound, and the separation effect is seriously reduced. Cyclone separators can be made of various materials, have wide operating condition range and high separation efficiency, so that the cyclone separators are still in chemical industry, mining, metallurgy, machinery, light industry and the like. Cyclone separators are not suitable for handling sticky dust, dust with high moisture content and corrosive dust.

The application is as follows: the valve plate of the double-layer heavy hammer flap valve is automatically opened under the action of gravity of materials, and after the materials fall down, the valve plate is automatically reset by the counterweight lever system to prevent wild wind from blowing in, so that the materials are conveyed.
