[0008] A method for using a crystalline silicon carbide processing wastewater recovery and treatment device comprises the following steps: Step 1: First, the filtered and separated processing wastewater enters the wastewater treatment tank from the water inlet pipe, and then the motor is started, and the motor rotates to drive the reciprocating screw to rotate; Step 2: The reciprocating screw rotates to drive the stirring plate to rotate, and the processing wastewater is mixed with the reagents added from the feeding box through the rotation of the stirring plate, and the pH value of the wastewater is adjusted to make the wastewater and the reagents mixed more fully; Step 3: The reciprocating screw rod rotates to drive the movable frame to reciprocate up and down along the fixed rod.

When the pH value is normal, the water inside is pumped out by the water pump for easy recycling.

[0009] According to the above technical solution, the liquid inlet control device includes a connecting frame, a hinged rod, a fixed seat, a sliding plate and a push plate. The movable frame moves up and down, which drives the connecting frame to move up and down. The connecting frame will pull the hinged rod upward when it moves upward. The hinged rod will pull the fixed seat toward the movable frame when it moves upward. The fixed seat moves toward the movable frame and drives the push plate toward the movable frame. The connecting frame is fixedly installed on the surface of the movable frame, the hinged rod is rotatably installed on the inner wall of the connecting frame, the sliding plate is slidably installed on the inner wall of the wastewater treatment tank, the push plate is fixedly installed on the surface of the sliding plate, the fixed seat is fixedly installed on the surface of the push plate, and the end of the hinged rod away from the connecting frame is rotatably installed on the inner wall of the fixed seat.

[0010] According to the above technical solution, a short plate is fixedly installed on the top of the push plate, a sealing ring is fixedly installed on the inner wall of the water inlet pipe, and a long rod slides through the surface of the sealing ring. The downward movement of the movable frame will push the push plate to move away from the movable frame, and the movement of the push plate away from the movable frame will drive the short plate to move away from the movable frame.

[0012] According to the above technical solution, a No. 2 spring is sleeved on the surface of the long rod. When the short plate is separated from the long rod, the No. 2 spring will drive the long rod to reset. The diameter of the sealing plate is larger than the circular hole of the sealing ring.

[0013] According to the above technical solution, the feeding device includes a trapezoidal plate, a sealing ring, a pulley rod, a sealing partition and a baffle. The movement of the short plate toward the direction close to the movable frame will drive the trapezoidal plate to move toward the movable frame.

When the pulley rod is separated from the trapezoidal plate, the No. 3 spring will drive the pulley rod to reset.

[0016] The present invention provides a device and method for recycling wastewater from crystalline silicon carbide processing. It has the following beneficial effects: (1) This invention mixes the processed wastewater with the reagent fed into the feeding box by rotating the stirring plate, adjusts the pH value in the wastewater, and makes the wastewater and the reagent mix more fully. The wastewater in the wastewater treatment box is turned up and down by the reciprocating movement of the hollow plate and the pulley frame, so that the wastewater settled at the bottom is turned upward and fully mixed with the reagent, thereby improving the mixing effect of the reagent and the wastewater and accelerating the reaction efficiency. When the pH value is normal, the water inside is pumped out by a water pump for easy recycling. The soft brush inside is moved away from the middle of the lamp holder by the sliding seat to scrape off the water mist attached to the ultraviolet lamp to prevent the water mist from isolating the ultraviolet lamp and affecting the sterilization effect of the ultraviolet lamp.

[0017] (2) This invention moves the push plate toward the moving frame to make the wastewater inside the wastewater treatment box sway left and right. The back-and-forth movement of the wastewater improves the wastewater treatment effect and the mixing of the reagent and the wastewater. The long rod moves toward the water inlet pipe to drive the sealing plate out of contact with the sealing ring, allowing the wastewater to enter the wastewater treatment box through the water inlet pipe. The water inlet pipe is opened intermittently to allow the wastewater to enter the wastewater treatment box, preventing too much wastewater from entering at one time, causing the load of the facility to exceed the design capacity and significantly reducing the treatment efficiency. The pulley moves up and down to drive the activated carbon plate up and down, so that the surface of the activated carbon plate can be more comprehensively exposed to the contaminated medium, avoiding the failure of some parts of the activated carbon due to being shielded for a long time.

[0018] (3) In this invention, the movement of the short plate toward the moving frame drives the trapezoidal plate toward the moving frame, and the movement of the trapezoidal plate toward the moving frame pushes the pulley rod upward, and the upward movement of the pulley rod drives the baffle plate upward, and the upward movement of the baffle plate breaks away from the contact with the sealing partition, so that the reagent inside the feeding box is fed into the wastewater treatment tank. By intermittently feeding the reagent, the reaction speed is controlled, making the treatment process more stable, avoiding premature reaction of the reagent or excessive reaction, resulting in reagent waste or poor treatment effect.

[0019] (4) In this invention, the upward movement of the pulley rod will drive the sealing block to move upward, and the upward movement of the sealing block will contact the sealing ring, and the sealing ring will be blocked by the sealing block, so that the medicine is stored between the sealing ring and the sealing partition. By quantitatively adding the medicine, excessive one-time addition is avoided, which leads to waste of medicine. The medicine entering the wastewater treatment box during reverse rotation can be spread more widely, thereby increasing the contact area between the medicine and the wastewater and improving the mixing efficiency. When the trapezoidal plate moves toward the moving frame, it will push the ball to move upward, and the upward movement of the ball will drive the sliding rod to move upward. The upward movement of the sliding rod will drive the circular slide to move upward. The upward movement of the circular slide pushes the medicine inside the feeding box to surge upward, thereby improving the mixing effect of the medicine. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A method for using a crystalline silicon carbide processing wastewater recovery and treatment device comprises the following steps: Step 1: First, the filtered and separated processing wastewater enters the wastewater treatment tank 1 through the water inlet pipe 2, and then the motor 4 is started, and the rotation of the motor 4 drives the reciprocating screw 5 to rotate; Step 2: The reciprocating screw 5 rotates to drive the stirring plate 6 to rotate, and the processing wastewater is mixed with the medicine fed into the feeding box 12 through the rotation of the stirring plate 6, and the pH value of the wastewater is adjusted to make the wastewater and the medicine mixed more fully; Step 3: The reciprocating screw rod 5 rotates to drive the movable frame 8 to reciprocate up and down along the fixed rod 7.

[0035] The movement of the short plate 136 toward the moving frame 8 will drive the trapezoidal plate 141 toward the moving frame 8, and the movement of the trapezoidal plate 141 toward the moving frame 8 will push the pulley rod 143 to move upward, and the upward movement of the pulley rod 143 will drive the baffle 145 to move upward, and the upward movement of the baffle 145 will break away from the contact with the sealing partition 144, so that the reagent inside the feeding box 12 is fed into the wastewater treatment box 1, and the reaction speed is controlled by intermittently feeding the reagent, making the treatment process more stable, avoiding premature reaction of the reagent or excessive reaction, resulting in waste of the reagent or poor treatment effect. At the same time, the upward movement of the pulley rod 143 will drive the sealing block 147 to move upward, and the sealing block 147 will contact the sealing ring 142 when it moves upward, and the sealing ring 142 is blocked by the sealing block 147, so that the reagent is stored between the sealing ring 142 and the sealing partition 144. The medicine is added in a quantitative manner to avoid excessive one-time addition, which leads to waste of medicine. At the same time, the sealing block 147 will drive the cross-turn plate 148 to move upward during its upward movement. After the cross-turn plate 148 moves upward, it is pushed in the reverse direction by the connecting screw rod 146, causing the cross-turn plate 148 to rotate. When the sealing block 147 moves downward, the cross-turn plate 148 will rotate in the opposite direction. The medicine entering the wastewater treatment box 1 during the reverse rotation can be spread more widely, thereby increasing the contact area between the medicine and the wastewater and improving the mixing efficiency. When the trapezoidal plate 141 moves toward the direction close to the movable frame 8, it will push the ball bearing 1410 to move upward. The upward movement of the ball bearing 1410 will drive the sliding rod 149 to move upward. The upward movement of the sliding rod 149 will drive the circular slide plate 1411 to move upward. The upward movement of the circular slide plate 1411 pushes the medicine inside the feeding box 12 to surge upward, thereby improving the mixing effect of the medicine.
