Description

Technical Field

[0001] This utility model belongs to the field of potassium dihydrogen phosphate production technology, and in particular relates to a wastewater treatment device in potassium dihydrogen phosphate production. Background Technology

[0002] Potassium dihydrogen phosphate is a colorless tetragonal crystal or white crystalline powder. Its relative density is 2.338. Its melting point is 252.6℃. It is readily soluble in water; at 90℃, its solubility is 83.5 g / 100 ml water. Its aqueous solution is acidic; a 1% potassium dihydrogen phosphate solution has a pH of 4.6. It is insoluble in alcohol. It is hygroscopic. When heated to 400°C, it melts into a transparent liquid, which solidifies upon cooling into an opaque, glassy form of potassium metaphosphate.

[0003] Existing methods for treating potassium dihydrogen phosphate wastewater typically involve separating impurities from the wastewater. However, the separated impurities contain a large amount of wastewater, which is usually discharged along with the impurities, causing environmental pollution. To address this, we provide a wastewater treatment device for potassium dihydrogen phosphate production. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device for potassium dihydrogen phosphate production. By moving the extrusion plate to the left, the impurities above the connecting plate are squeezed, causing the wastewater inside to fall through the filter plate into the conveying pipe, and then into the treatment tank through the conveying pipe. This reduces environmental pollution and improves water resource recovery. It solves the problem that existing separated impurities contain a large amount of wastewater, which is usually discharged along with the impurities, causing environmental pollution.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a wastewater treatment device in the production of potassium dihydrogen phosphate, including an extrusion box, a hydraulic device fixedly connected to the inner wall of the extrusion box, an extrusion plate fixedly connected to the left output end of the hydraulic device, a baffle plate in contact with the top of the extrusion plate, and a connecting plate in contact with the bottom of the extrusion plate.

[0007] Both the connecting plate and the baffle have slots near the extrusion plate. A boss is slidably connected to the inner wall of the top of the extrusion plate, and the top of the boss matches the inner wall of the slot at the bottom of the baffle. A spring is fixedly connected to the bottom of the boss, and the bottom of the spring is fixedly connected to the inner wall of the extrusion plate. A second protrusion is slidably connected to the inner wall of the bottom of the extrusion plate, and the bottom of the second protrusion matches the inner wall of the slot at the top of the connecting plate. A second spring is fixedly connected to the top of the second protrusion, and the top of the spring is fixedly connected to the inner wall of the extrusion plate. A filter plate is fixedly connected to the inner wall of the connecting plate. The extrusion plate moves to the left to squeeze impurities above the connecting plate, causing the wastewater inside to fall through the filter plate into the conveying pipe, and then into the treatment tank through the conveying pipe, reducing environmental pollution and improving water resource recovery.

[0008] Furthermore, a conveying pipe is fixedly connected to the bottom of the connecting plate, and a feed inlet is opened inside the extrusion box. The feed inlet is located above the extrusion box. The outer surface of the connecting plate is slidably connected to the inner wall of the extrusion box. Protrusion 1 and Protrusion 2 are set as arcs, and the arcs are adapted to the slots. Therefore, protrusion 1 and Protrusion 2 can be disengaged from the slots by extrusion.

[0009] Furthermore, the outer surface of the baffle is slidably connected to the inner wall of the extrusion box, a limiting groove is provided at the top of the extrusion box, a push-pull rod is slidably connected to the inner wall of the limiting groove, and the bottom of the push-pull rod extends into the interior of the extrusion box. The limiting groove is used to limit the push-pull rod so that it will not deviate when moving.

[0010] Furthermore, a cleaning plate is rotatably connected to the inner wall of the push-pull rod, a return spring is fixedly connected to the inner wall of the cleaning plate, a connecting rod is fixedly connected to the front of the return spring, the front of the connecting rod passes through the extrusion box, a locking block is fixedly connected to the outer surface of the connecting rod, an entry groove is opened inside the cleaning plate, and a locking slot is opened on the front of the push-pull rod. There are two locking slots in total. The inner wall of the entry groove and the locking slot engages with the outer surface of the locking block. When the cleaning plate is rotated to vertical, releasing the connecting rod locking block will push the return spring to push it into the other locking slot.

[0011] Furthermore, a processing box is fixedly connected to the right side of the extrusion box, a motor is fixedly connected to the top of the processing box, a cover plate is rotatably connected to the top of the processing box, a connecting rod is fixedly connected to the bottom output end of the motor via a coupling, a second filter plate is fixedly connected to the inner wall of the processing box, and the end of the connecting rod away from the motor extends into the interior of the second filter plate. The interior of the second filter plate is slidably connected to the outer surface of the connecting rod. The second filter plate separates impurities in the wastewater, allowing the impurities to remain above the second filter plate. Then, the connecting rod rotates to drive the cleaning brush to rotate, simultaneously cleaning the filter plate.

[0012] Furthermore, a fixing ring is fixedly connected to the outer surface of the connecting rod, and a cleaning brush is fixedly connected to the right side of the fixing ring. The bottom of the cleaning brush contacts the top of the second filter plate. A discharge port is fixedly connected to the bottom of the treatment box, and a sealing cap is threadedly connected to the outer surface of the discharge port. The left side of the treatment box is fixedly connected to the right side of the conveying pipe. An inclined baffle is fixedly connected to the inner wall of the treatment box near the extrusion box. The inclined baffle has a certain height, which prevents wastewater from entering the extrusion box through the feed inlet.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model incorporates an extrusion plate, specifically, the extrusion plate moves to the left, simultaneously driving the connecting plate to move as well. During the leftward movement of the connecting plate, it first contacts the inner wall of the extrusion chamber. Simultaneously, the second protrusion disengages from the slot in the connecting plate. When the connecting plate reaches the far left, the conveying pipe is straightened, and the extrusion plate moves to the left to extrude impurities above the connecting plate, causing the wastewater inside to fall through the filter plate into the conveying pipe, and then into the treatment chamber, thus reducing environmental pollution and improving water resource recovery.

[0015] 2. This utility model incorporates a cleaning plate. Specifically, when the connecting rod is pushed, it causes the locking block to disengage from the locking slot and enter the inlet slot, simultaneously compressing the return spring. Then, the connecting rod is rotated, causing the cleaning plate to rotate 90 degrees. After releasing the connecting rod, the return spring rebounds, pushing the locking block back into the locking slot. Then, the push-pull rod is pulled to the left, simultaneously moving the cleaning plate. The movement of the cleaning plate then pushes the impurities remaining on the inner wall of the feed inlet into the drop inlet, where they fall onto the connecting plate. This prevents impurities from accumulating inside the feed inlet for extended periods, causing corrosion of the device and reducing its service life.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 As shown, this utility model is a wastewater treatment device in the production of potassium dihydrogen phosphate, including an extrusion box 101. A hydraulic device 111 is fixedly connected to the inner wall of the extrusion box 101. An extrusion plate 107 is fixedly connected to the left output end of the hydraulic device 111. A baffle 105 is in contact with the top of the extrusion plate 107, and a connecting plate 103 is in contact with the bottom of the extrusion plate 107.

[0028] Both the connecting plate 103 and the baffle 105 have slots at their ends near the extrusion plate 107. A boss 106 is slidably connected to the inner wall of the top of the extrusion plate 107. The top of the boss 106 matches the inner wall of the slot at the bottom of the baffle 105. A spring 108 is fixedly connected to the bottom of the boss 106, and the bottom of the spring 108 is fixedly connected to the inner wall of the extrusion plate 107. A second protrusion 109 is slidably connected to the inner wall of the bottom of the extrusion plate 107. The bottom of the second protrusion 109 matches the inner wall of the slot at the top of the connecting plate 103. A second spring 110 is fixedly connected to the top of the second protrusion 109, and the top of the spring 110 is fixedly connected to the inner wall of the extrusion plate 107. A filter plate 104 is fixedly connected to the inner wall of the connecting plate 103. Plate 107 moves to the left, simultaneously driving connecting plate 103 to move as well. During the leftward movement of connecting plate 103, it first contacts the inner wall of extrusion box 101. Simultaneously, protrusion 109 disengages from the slot in connecting plate 103. When connecting plate 103 reaches the far left, conveying pipe 112 is straightened. At the same time, extrusion plate 107 moves to the left to extrude impurities above connecting plate 103, causing wastewater inside to fall through filter plate 104 into conveying pipe 112, and then into treatment box 201 through conveying pipe 112, reducing environmental pollution and improving water resource recovery.

[0029] The bottom of the connecting plate 103 is fixedly connected to the conveying pipe 112. The extrusion box 101 has an inlet 102 inside, which is located above the extrusion box 101. The outer surface of the connecting plate 103 is slidably connected to the inner wall of the extrusion box 101.

[0030] The outer surface of the baffle 105 is slidably connected to the inner wall of the extrusion box 101. A limiting groove 113 is provided at the top of the extrusion box 101. A push-pull rod 115 is slidably connected to the inner wall of the limiting groove 113. The bottom of the push-pull rod 115 extends into the interior of the extrusion box 101.

[0031] A cleaning plate 120 is rotatably connected to the inner wall of the push-pull rod 115. A return spring 116 is fixedly connected to the inner wall of the cleaning plate 120. A connecting rod 114 is fixedly connected to the front of the return spring 116. The front of the connecting rod 114 passes through the extrusion box 101. A locking block 118 is fixedly connected to the outer surface of the connecting rod 114. An entry groove 119 is opened inside the cleaning plate 120. A locking groove 117 is opened on the front of the push-pull rod 115. There are two locking grooves 117. The inner wall of the entry groove 119 and the locking groove 117 engages with the outer surface of the locking block 118. When the connecting rod 114 is pushed, it causes the locking block 118 to disengage from the locking groove 117 and enter the entry groove 119, and at the same time, it engages the extrusion box 101. The spring 116 is pressed, and then the connecting rod 114 is rotated. When the connecting rod 114 rotates, it drives the cleaning plate 120 to rotate 90 degrees. Then the connecting rod 114 is released, and the return spring 116 rebounds to push the locking block 118 back into the locking groove 117. Then the push-pull rod 115 is pulled to the left. When the push-pull rod 115 moves to the left, it will drive the cleaning plate 120 to move at the same time. Then the cleaning plate 120 moves to push the impurities remaining on the inner wall of the feed port 102 into the drop inlet and fall onto the connecting plate 103. This prevents impurities from accumulating inside the feed port 102 for a long time, causing the device to be corroded and reducing its service life.

[0032] A processing box 201 is fixedly connected to the right side of the extrusion box 101. A motor 202 is fixedly connected to the top of the processing box 201. A cover plate 203 is rotatably connected to the top of the processing box 201. A connecting rod 204 is fixedly connected to the bottom output end of the motor 202 through a coupling.

[0033] A filter plate 207 is fixedly connected to the inner wall of the processing box 201. The end of the connecting rod 204 away from the motor 202 extends into the interior of the filter plate 207. The interior of the filter plate 207 is slidably connected to the outer surface of the connecting rod 204.

[0034] A fixing ring 206 is fixedly connected to the outer surface of the connecting rod 204. A cleaning brush 205 is fixedly connected to the right side of the fixing ring 206. The bottom of the cleaning brush 205 is in contact with the top of the filter plate 207.

[0035] The bottom of the processing box 201 is fixedly connected to the discharge port 208, and the outer surface of the discharge port 208 is threadedly connected to the sealing cover 209. The left side of the processing box 201 is fixedly connected to the right side of the conveying pipe 112, and the inner wall of the processing box 201 near the extrusion box 101 is fixedly connected to the inclined stop 210.

[0036] A specific application of this embodiment is as follows: The worker first opens the cover plate 203, then pours the wastewater into the treatment tank 201. Simultaneously, the sealing cover 209 is opened to send the filtered wastewater to the next process. When the wastewater enters the treatment tank 201, it is first blocked by the second filter plate 207, causing impurities in the wastewater to remain above the second filter plate 207. Then, the motor 202 is started, driving the connecting rod 204 to rotate. The rotation of the connecting rod 204 then drives the fixed ring 206 to rotate, which in turn drives the cleaning brush 205 to rotate. This causes the cleaning brush 205 to push the impurities above the second filter plate 207 into the squeezing box 101, simultaneously cleaning the filter... The holes in plate 207 are cleaned briefly. Impurities entering the extrusion chamber 101 are gradually pushed by subsequent impurities, causing them to fall onto the connecting plate 103. Then, the hydraulic actuator 111 is activated, pushing the extrusion plate 107 to the left. The movement of the extrusion plate 107 then drives the baffle 105 and the connecting plate 103 to move synchronously. During the movement of the baffle 105 and the connecting plate 103 to the left, the baffle 105 will first contact the inner wall of the extrusion chamber 101, sealing the impurity inlet. At the same time, the boss 106 will disengage from the slot in the baffle 105. After the baffle 105 seals the inlet, the extrusion plate 107 will move to the left, synchronously driving the connecting plate 103 to move as well. As the connecting plate 103 moves to the left, it first contacts the inner wall of the extrusion box 101. Simultaneously, the second protrusion 109 disengages from the slot in the connecting plate 103. When the connecting plate 103 reaches its leftmost position, the conveying pipe 112 is taut. At the same time, the extrusion plate 107 moves to the left to extrude impurities above the connecting plate 103, causing the wastewater inside to fall through the filter plate 104 into the conveying pipe 112, and then into the treatment box 201, reducing environmental pollution and improving water resource recovery. After extrusion, the extrusion plate 107 retracts and resets the connecting plate 103 and the baffle 105, then pushes the connecting rod 114. When 114 is pushed, it causes the locking block 118 to disengage from the locking slot 117 and enter the inlet slot 119, while simultaneously squeezing the return spring 116. Then, the connecting rod 114 is rotated, which drives the cleaning plate 120 to rotate 90 degrees. Then, the connecting rod 114 is released, and the return spring 116 rebounds, pushing the locking block 118 back into the locking slot 117. Then, the push-pull rod 115 is pulled to the left. When the push-pull rod 115 moves to the left, it simultaneously drives the cleaning plate 120 to move. Then, the movement of the cleaning plate 120 pushes the impurities remaining on the inner wall of the feed inlet 102 into the drop inlet and onto the connecting plate 103, preventing impurities from accumulating inside the feed inlet 102 for a long time, causing corrosion of the device and reducing its service life.
