[0017] As shown in the accompanying drawings, the utility model includes a crusher 1, a feed chute 2, an air supply duct 3, a blower 4, a conveyor 5, an exhaust duct 6 and an ejector 7.

[0018] The crusher 1 is installed on the frame, and the top of the crusher 1 is symmetrically provided with a feed port and a fine powder discharge pipe 8. The bottom discharge port of the crusher 1 is connected to the top feed port of the discharge chute 2, and a vent is provided on the lower outer wall of the discharge chute 2. The air supply duct 3 consists of an inclined pipe and a horizontal pipe. The inclined pipe outlet end of the air supply duct 3 is connected to the vent of the discharge chute 2, and the horizontal pipe inlet end of the air supply duct 3 is connected to the air outlet of the blower 4. The conveyor 5 is located at the bottom of the discharge chute 2, the air suction pipe of the ejector 7 is connected to the fine powder discharge pipe 8, and the nozzle of the ejector 7 is connected to the water outlet of the water pump through the water inlet pipe. A first gate valve is provided at the feed port of the crusher 1, and a second gate valve is provided at the lower part of the discharge chute 2 and is located below the vent.

[0019] An inclined buffer plate 9 is provided in the bottom discharge port of the discharge chute 2, and the inclined buffer plate 9 is located below the second gate valve.

[0020] The conveyor 5 is a belt conveyor.

[0021] The angle between the inclined center line of the air supply duct 3 and the horizontal plane is α, and α is 50-60°.

[0022] Working Principle: Coagulant to be crushed is added through the feed port of crusher 1. After a certain amount has been added, the first gate valve at the feed port of crusher 1 is closed, and crusher 1 and blower 4 are started. Fine coagulant particles, crushed by crusher 1, fall through the discharge port at the bottom of crusher 1 into the feed chute 2. Air from blower 4 separates the fine particles, causing them to float upwards through the gaps within crusher 1 and be injected into the nozzle of ejector 7, where the wastewater to be coagulated is injected. This creates a negative pressure within ejector 7, which draws the fine coagulant particles from the crusher 1 cavity through exhaust duct 6. These particles, mixed with the wastewater in ejector 7, are then sprayed into a designated container for sedimentation. Once the material in crusher 1 is completely crushed, the first gate valve is opened to allow further feeding. Larger coagulant particles first fall onto the inclined buffer plate 9, where they are buffered before falling onto the feed end of conveyor 5. Conveyor 5 then transports them to the feed device above crusher 1, where they await further crushing. When the conveyor 5 has a conveying failure and needs to be repaired, the crusher 1 can be shut down and the second gate valve can be closed to prevent the coagulant particles from falling on the conveyor 5. The top of the feed chute 2 is funnel-shaped and is used to connect with the crusher discharge port.
