Filter valve for gas-solid two-phase flow

[0010] Example 1

[0011] The present invention is a new type of filter valve for two-phase flow, which includes a valve body 1, a valve plate 2, a sealing ring, a clamping plate 4, a flow equalizing plate 5, a vibrating screen 6, a receiving plate 7, a slag discharge pipe 8, and the inner side of the valve body 1. A valve plate 2 is installed, and a sealing ring is installed between the valve body 1 and the valve plate 2. A flow plate 5 is installed on the front side of the valve plate 2, a vibrating screen 6 is installed on the front side of the flow plate 5, and the front side of the vibrating screen 6 is opened. Slag discharge port, the upper side of the slag discharge port is installed with a receiving plate 7, the lower end of the receiving plate 7 is installed with a clamping plate 4, the clamping plate 4 is a movable structure, and the lower side of the clamping plate 4 is installed with a spring 3, a slag discharge port and a slag pipe 8 connection, a micro motor is instal

[0012] Example 2

[0013] When in use, the gas-solid two-phase flow passes through the vibrating screen 6, and the solid impurities are blocked and vibrated by the vibrating screen 6, and fall on the receiving plate 7 on the lower side, and then the air flows through the flow-sharing plate 5 and is used by the flow-sharing plate 5. , The impact force is reduced, reducing the momentum of the air flow through the valve. When the pressure on the upper side of the receiving plate 7 is too large, the clamping plate 4 on the lower side of the receiving plate 7 will tilt downward under the pressure, and the receiving plate 7 will also tilt downward, and the impurities on the upper side will directly fall into the slag discharge pipe 8. Alleviate, the card board 4 springs back to its original position under the action of the lower spring 3, and the receiving board 7 continues to receive impurities.
