[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a flow channel cleaning component on the outer side of the discharge valve body. After the splitter blade compensating split sealing port is opened, the flow channel cleaning component scrapes and absorbs the dust and impurities on the inner wall of the splitter blade, cleans and dredges the impurities, dust and lumps in the air flow channel of the blade, improves the gas circulation efficiency, and reduces the blockage phenomenon. The dredged air flow channel can maintain the uniformity and stability of the air flow. The impurities and dust in the pipeline will cause wear to the impeller and the gas pipeline. After cleaning and dredging, this wear can be reduced, and the service life of the splitter blade is extended. The cleaned and dredged air flow channel can more effectively transmit the compensating air pressure, ensure the sealing performance and discharge efficiency of the rotary discharge valve, and improve the stability of the rotary discharge valve during operation. The cleaned and dredged air flow channel can maintain the sealing performance, prevent gas leakage, and ensure the safety of the production environment.

[0019] 2. The present invention installs a gas flow sensor on the inner wall of the splitter blade. The gas flow sensor detects the compensating airflow in real time. The presence of impurities in the blade airflow channel within a group of splitter blades will cause the corresponding airflow to weaken. The gas flow sensor captures slight airflow changes and accurately reflects the state of the blade airflow channel. The gas flow sensor has a fast response speed. When it detects that impurities exist in the blade airflow channel within a group of splitter blades, causing the airflow to weaken, it immediately transmits a signal and locates. The severe blocked splitter blades can be quickly located, which is convenient for the staff to carry out directional maintenance, thereby improving the maintenance efficiency, helping to improve the reliability and stability of the rotary unloading valve, and extending the service life of the rotary unloading valve.

[0020] 3. In the present invention, a fluororubber seal is installed on the outer side of the wear-resistant bushing. The lubricant in the storage box flows out through the falling flow channel, the transmission flow channel and the dispersion flow channel in sequence to lubricate the fitting position between the fluororubber seal and the inner cavity of the discharge valve body. Continuous lubrication can reduce the friction between the seal and the inner cavity of the discharge valve body and reduce wear, thereby ensuring a close fit between the two. The close fit helps to prevent gas leakage, improve the sealing performance of the rotary discharge valve, and ensure the stability and efficiency of the system. Continuous lubrication can ensure that the rotary discharge valve is more stable during operation, reduce vibration and noise, help improve the operation quality of the equipment, and ensure that the material will not leak from the fitting position during the discharge process.

[0021] 4. The present invention installs a convection cooling hood on the inner side of the discharge valve body, and the reciprocating hand lever drives the crushing head to extrude the agglomerated material, and the cooling fan cools the input material. The crushing of agglomerates can effectively reduce the size of material particles, making it more in line with the design requirements of the rotary discharge valve. The impact and wear of smaller material particles on the seal when passing through the valve will be greatly reduced. Cooling can reduce the temperature of material particles, thereby reducing the thermal expansion and softening of the seal caused by high temperature, thereby reducing the risk of wear. Controlling the particle size and temperature of the material significantly reduces the amount of wear of the seal during operation. The crushing of agglomerates and cooling can ensure the smooth flow of materials in the rotary discharge valve, reduce blockage and jamming, help improve production efficiency, and help maintain the continuity and stability of the discharge valve during use.

The gas flow sensor 22 detects the compensating airflow in real time. The presence of impurities in the blade airflow channel 28 in a group of split blades 4 will cause the corresponding airflow to weaken. The gas flow sensor 22 captures the slight airflow change to accurately reflect the state of the blade airflow channel 28. When it is detected that the blade airflow channel 28 in a group of split blades 4 has impurities that cause the airflow to weaken, it immediately transmits a signal and locates it.

The operation of the rotary motor 12 drives the rotor shaft 3 to rotate and fill the space between the diverter blades 4 with the falling material. After the material rotates to the bottom, it falls by its own weight. The infrared detector 13 detects the block material. After the block material is detected, the reciprocating hand lever 14 drives the crushing head 15 to squeeze the agglomerated material.
