Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic production technology, specifically a recycling device used in photovoltaic production. Background Technology

[0002] In the current rapid development of the photovoltaic industry, the problem of waste liquid treatment generated during photovoltaic production has become increasingly prominent. Photovoltaic waste liquid contains many harmful impurity ions as well as valuable substances such as calcium fluoride. If it cannot be effectively recycled and treated, the waste liquid will cause serious pollution to the environment, lead to waste of resources, and increase the production costs of enterprises.

[0003] Traditional photovoltaic waste liquid treatment methods have certain limitations. For example, simple precipitation methods have low treatment efficiency and slow precipitation speed, making it difficult to achieve deep removal of impurity ions in the waste liquid. Furthermore, the purity of the calcium fluoride sludge after precipitation is not high, which is not conducive to subsequent resource recycling.

[0004] When filtration is used alone, the filtration effect is easily affected by factors such as the viscosity of the waste liquid and the distribution of impurities. The filter cake is unevenly formed, the filtration speed is unstable, and it cannot solve the problem of sufficient mixing and reaction between the waste liquid and the drug. It cannot effectively remove impurity ions, and the resulting waste calcium fluoride sludge has low purity, which is not conducive to resource recovery. Therefore, a recovery device for photovoltaic production is proposed to address the above problems. Utility Model Content

The diameter of the buoyancy plate and the cover plate is larger than the diameter of the guide hole, and the buoyancy of the buoyancy plate is greater than the weight of the cover plate.

[0012] Preferably, the bottom side of the cover plate is fixed with supporting protrusions in a circular array. The length of the supporting protrusions is less than the thickness difference between the supporting rod and the movable disc. The bottom of the mixing tank is connected to a pressure pipe, and the other end of the pressure pipe is connected to the middle of the filter press pipe. This can help to pressurize and transport the mixture. After pressurization and transport, the sludge in the mixture can be better separated by the filter bag.

[0013] Preferably, a horizontally placed hollow cylinder is installed in the middle of the infusion tube, and a storage hopper is installed above the horizontally placed hollow cylinder. The infusion tube, the horizontally placed hollow cylinder, and the storage hopper are connected in a through-hole structure.

Actuating plates are arranged in a ring array on the outer surface of the actuating shaft. The axis of the actuating shaft is on the same straight line as the axis of the horizontally placed hollow cylinder, and the side of the actuating plates is clearance-fitted with the inner wall of the horizontally placed hollow cylinder. The infusion tube is connected to the mixing tank, and the connection position of the infusion tube is located above the upward movement limit position of the guide hole, so that the reaction agent can be delivered in a matching manner through the flow of waste liquid.

[0015] Preferably, the sedimentation tank has a drain pipe mounted on the top of both side walls, and the filter press pipe has a discharge port at the top, with a drain nozzle connected to the discharge port. The drain nozzle is located above the guide channel of the drain pipe.

[0016] The advantages of this utility model are:

[0017] Through the coordinated action of components such as the movable disc, rotating disc, and stirring rod, the stirring rod rotates up and down within the mixing tank, and the rotating disc rotates in opposite directions as it moves up or down, causing the stirring rod to stir the mixture at different shear angles. This allows the added mixed drugs and waste liquid to better fuse and react, effectively improving the mixing effect of drugs and waste liquid, thereby increasing the waste liquid treatment efficiency and promoting the effect of waste liquid recycling and treatment in photovoltaic production.

[0018] The design of the filter press structure, including the coordination of components such as the filter press tube, lifting motor, auger, and filter bag, allows the mixed waste liquid to enter the filter press tube under pressure. Water is squeezed out by the filter bag, while suspended solids are retained in the filter press tube, achieving solid-liquid separation. The separated calcium fluoride sludge can be lifted upward by the auger, providing space for subsequent filtration. The setting of the drain nozzle and drain pipe can also achieve solid-liquid separation, improve the solid-liquid separation effect and the purity of the calcium fluoride sludge, further optimize the recovery effect, and reduce the treatment difficulty of the precipitated calcium fluoride sludge produced by simple sedimentation.

[0019] The structure, including a horizontally placed hollow cylinder, a storage hopper, and internally rotating actuating shaft and actuating plates installed in the middle of the infusion pipe, allows the reagent in the storage hopper to enter the infusion pipe through the horizontally placed hollow cylinder and mix with the waste liquid in the infusion pipe. As the waste liquid flows through the infusion pipe, it generates an impact force on the actuating plates, driving the actuating shaft to rotate. This rotation causes the actuating plates to evenly carry the reagent in the storage hopper into the infusion pipe and mix with the waste liquid, achieving matched dosing within a suitable range. This ensures that the dosage and waste material are matched within a reasonable range, improving the treatment effect of the waste liquid. At the same time, the entire process does not require stopping the mixing and dosing operation, ensuring the relative continuity of the wastewater treatment process and improving wastewater treatment efficiency.

[0028] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] To ensure thorough mixing of photovoltaic production waste liquid and reagents, please refer to [link / reference needed]. Figure 1-2 , Figure 4 As shown, a recycling device for photovoltaic production includes: a liquid delivery pipe 1 and a mixing structure 3, wherein the liquid delivery pipe 1 is connected to a mixing tank 31 on the mixing structure 3;

[0031] The mixing structure 3 includes a mixing tank 31. A screw 38 is vertically installed at the center of the bottom inner wall of the mixing tank 31. The outer side of the screw 38 is provided with an external thread. A threaded hole is provided at the center of the rotating disk 39. The rotating disk 39 is rotatably installed on the outside of the screw 38. The threaded hole wall of the rotating disk 39 is clearance-fitted with the external thread surface of the screw 38. When the rotating disk 39 is pushed to move up and down, the inner wall of the rotating disk 39 can rotate and slide along the outer wall of the screw 38. Under the guidance of the external thread of the screw 38, the rotating disk 39 can simultaneously achieve rotation operation during the up and down movement.

[0032] A bearing is installed on the top side of the rotating disk 39, and the rotating disk 39 is connected to the outer ring of the bearing. A fixed disk 36 is installed on the bearing, and the fixed disk 36 is connected to the inner ring of the bearing. The fixed disk 36 serves as the upper and lower force-bearing structure. The fixed disk 36 and the rotating disk 39 are connected by the bearing. During the synchronous up and down movement of the fixed disk 36 and the rotating disk 39, the rotating disk 39 rotates relative to the fixed disk 36, so that the rotating disk 39 can rotate along the external thread structure of the screw 38. This ensures the stability of the force on the rotating disk 39 and prevents motion interference during connection.

[0033] Four connecting rods 310 are vertically fixed at a 90° angle on the top side of the fixed disk 36. A stirring rod 37 is fixed on the outer side of the rotating disk 39. The stirring rod 37 is fixed by a cross-shaped cross of horizontal and vertical rods. The middle part of the stirring rod 37 is connected to the outer side of the rotating disk 39. The stirring rod 37 has a cross-shaped frame structure. When the rotating disk 39 rotates up and down, it drives the stirring rod 37 to rotate up and down. When the rotating disk 39 moves downward, the rotating disk 39 and the stirring rod 37 rotate downward synchronously. The stirring area of ​​the stirring rod 37 is located at the lower part of the mixing tank 31. When the rotating disk 39 moves upward, the rotating disk 39 and the stirring rod 37 rotate upward synchronously. The stirring area of ​​the stirring rod 37 is located at the upper part of the mixing tank 31. During the upward or downward movement of the rotating disk 39, the rotation direction of the rotating disk 39 is opposite, which can drive the stirring rod 37 to stir the mixture at different shear angles, so that the fed mixed drugs and waste liquid can better fuse and react.

[0034] The top ends of the four connecting rods 310 are synchronously fixed with movable discs 35. The movable discs 35 are located inside the mixing tank 31. The outer circumferential surface of the movable discs 35 is fitted with the inner circumferential wall of the mixing tank 31 with a clearance. The vertical sliding distance of the movable discs 35 is the same as the vertical rotation distance of the rotating discs 39. When the movable discs 35 are subjected to vertical traction force, they can slide inside the mixing tank 31. During the sliding process, they can drive the fixed discs 36 to move up and down, thereby realizing the forward and reverse rotation operation of the rotating discs 39. With the cooperation of the stirring rods 37, the mixture is stirred, improving the mixing effect of the drug and the waste liquid.

[0036] To ensure thorough mixing of photovoltaic production waste liquid and reagents, please refer to [link / reference needed]. Figure 1-2 , Figure 4 As shown, to ensure thorough mixing of photovoltaic production waste liquid and reagents, please refer to [link / reference needed]. Figure 1-3 As shown, a recycling device for photovoltaic production includes: a liquid delivery pipe 1 and a mixing structure 3, wherein the liquid delivery pipe 1 is connected to a mixing tank 31 on the mixing structure 3;

[0037] The mixing structure 3 includes a mixing barrel 31. A screw 38 is vertically installed at the center of the bottom inner wall of the mixing barrel 31. The outer side of the screw 38 is provided with an external thread. A threaded hole is provided at the center of the rotating disk 39. The rotating disk 39 is rotatably installed on the outside of the screw 38. The threaded hole wall of the rotating disk 39 is clearance-fitted with the external thread surface of the screw 38.

[0038] A bearing is installed on the top side of the rotating disk 39, and the rotating disk 39 is connected to the outer ring of the bearing. A fixed disk 36 is installed on the bearing, and the fixed disk 36 is connected to the inner ring of the bearing. Four connecting rods 310 are vertically fixed at a 90° angle on the top side of the fixed disk 36. A stirring rod 37 is fixed on the outer side of the rotating disk 39. The stirring rod 37 is fixed by a cross-shaped crossbar and a vertical bar. The middle part of the stirring rod 37 is connected to the outer side of the rotating disk 39.

[0039] The top ends of the four connecting rods 310 are simultaneously fixed with movable discs 35. The movable discs 35 are located inside the mixing barrel 31. The outer circumferential surface of the movable discs 35 is fitted with the inner circumferential wall of the mixing barrel 31 with a clearance. The vertical sliding distance of the movable discs 35 is the same as the vertical rotation distance of the horizontal hollow cylinder 9.

[0040] The mixing structure 3 also includes a mounting plate 315. A lifting motor 317 is fixed to the top center of the mounting plate 315. A rotating disk 316 is mounted on the output shaft of the lifting motor 317. A pull rod 32 is connected to the eccentric point of the rotating disk 316 via a pin. The top of the pull rod 32 is located at the eccentric position of the rotating disk 316. During the rotation of the rotating disk 316, the top of the pull rod 32 can be driven to deflect up and down, so that the pull rod 32 generates a height difference during the movement. A connecting seat 33 is fixed to the top side of the fixed disk 36. The bottom end of the pull rod 32 is connected to the connecting seat 33 via a pin. Under the action of the rotating disk 316, the pull rod 32 generates a height difference. Under the traction of the pull rod 32, the connecting seat 33 moves up and down, so that the mounting plate 315 connected to the bottom side of the connecting seat 33 moves up and down.

[0041] In use, after the waste liquid containing the reaction drug is discharged into 31, operation 317 drives 316 to rotate. During the rotation of the rotating disk 316, the top of the pull rod 32 deflects up and down, causing a height difference in the pull rod 32. When the movable disk 35 is subjected to the vertical traction force, it can slide within the mixing tank 31. During the sliding process, it can drive the fixed disk 36 to move up and down. The fixed disk 36 serves as the vertical force-bearing structure. The fixed disk 36 and the rotating disk 39 are connected by bearings. During the synchronous vertical movement of the fixed disk 36 and the rotating disk 39, the rotating disk 39 rotates relative to the fixed disk 36, allowing the rotating disk 39 to move along the external thread of the screw 38. The stirring rod 37 rotates because it has a cross-shaped frame structure. When the rotating disk 39 rotates up and down, it drives the stirring rod 37 to rotate up and down as well. When the rotating disk 39 moves downward, the rotating disk 39 and the stirring rod 37 rotate downward synchronously, and the stirring area of ​​the stirring rod 37 is located at the lower part of the mixing tank 31. When the rotating disk 39 moves upward, the rotating disk 39 and the stirring rod 37 rotate upward synchronously, and the stirring area of ​​the stirring rod 37 is located at the upper part of the mixing tank 31. Furthermore, the rotating disk 39 rotates in opposite directions during its upward or downward movement, which enables the stirring rod 37 to stir the mixture at different shear angles, allowing the added mixed drugs and waste liquid to better fuse and react.

[0043] To ensure thorough mixing of photovoltaic production waste liquid and reagents, please refer to [link / reference needed]. Figure 1-2 , Figure 4 As shown, a recycling device for photovoltaic production includes: a liquid delivery pipe 1 and a mixing structure 3, wherein the liquid delivery pipe 1 is connected to a mixing tank 31 on the mixing structure 3;

[0044] The mixing structure 3 includes a mixing barrel 31. A screw 38 is vertically installed at the center of the bottom inner wall of the mixing barrel 31. The outer side of the screw 38 is provided with an external thread. A threaded hole is provided at the center of the rotating disk 39. The rotating disk 39 is rotatably installed on the outside of the screw 38. The threaded hole wall of the rotating disk 39 is clearance-fitted with the external thread surface of the screw 38.

[0045] A bearing is installed on the top side of the rotating disk 39, and the rotating disk 39 is connected to the outer ring of the bearing. A fixed disk 36 is installed on the bearing, and the fixed disk 36 is connected to the inner ring of the bearing. Four connecting rods 310 are vertically fixed at a 90° angle on the top side of the fixed disk 36. A stirring rod 37 is fixed on the outer side of the rotating disk 39. The stirring rod 37 is fixed by a cross-shaped crossbar and a vertical bar. The middle part of the stirring rod 37 is connected to the outer side of the rotating disk 39.

[0046] The top ends of the four connecting rods 310 are simultaneously fixed with movable discs 35. The movable discs 35 are located inside the mixing barrel 31. The outer circumferential surface of the movable discs 35 is fitted with the inner circumferential wall of the mixing barrel 31 with a clearance. The vertical sliding distance of the movable discs 35 is the same as the vertical rotation distance of the horizontal hollow cylinder 9.

[0047] The movable disk 35 has a ring-shaped array of flow guide holes 34 inside. A support rod 312 is installed inside each flow guide hole 34. The diameter of the support rod 312 is smaller than the inner diameter of the flow guide hole 34. There is a flow gap between the support rod 312 and the flow guide hole 34. A cover plate 314 is fixed to the top of the support rod 312, and a buoyancy plate 311 is fixed to the bottom of the support rod 312. The diameters of the buoyancy plate 311 and the cover plate 314 are larger than the diameter of the flow guide hole 34. The buoyancy plate 311 can be lifted by the buoyancy force below. Combined with the movable disc 35, it forms an integral pressing structure. The buoyancy of the buoyancy plate 311 is greater than the weight of the cover plate 314. After the waste liquid and the medicine are mixed, in order to achieve a better mixing effect, when the movable disc 35 moves downward, since the bottom of the mixing tank 31 is full of mixed liquid, when the movable disc 35 descends, the buoyancy plate 311 blocks the bottom port of the guide hole 34 under the action of buoyancy. With the cooperation of the movable disc 35 and the buoyancy plate 311, the entire pressing surface can be completed, similar to the action of a piston, squeezing out the mixed liquid.

[0048] After the movable disc 35 is pushed down, as the movable disc 35 rises, the buoyancy plate 311 is no longer supported by buoyancy. Under its own weight and the weight of the cover plate 314 and the support rod 312, it separates from the lower end of the guide hole 34, so that the upper and lower spaces of the movable disc 35 are in a through state through the guide hole 34. The mixed liquid can enter the lower part of the movable disc 35 from the top through the guide hole 34 to carry out mixing and stirring operations. The pushing operation can be achieved without affecting the normal feeding.

The buoyancy of the buoyancy plate 311 is greater than the weight of the cover plate 314.

[0055] The bottom side of the cover plate 314 is fixed with support protrusions 313 in a ring array, which can prevent the cover plate 314 from sealing the upper port of the guide hole 34 when the buoyancy plate 311 is not pushed by the buoyancy below. The length of the support protrusions 313 is less than the thickness difference between the support rod 312 and the movable plate 35, ensuring that there is a good liquid flow space in the upper and lower space of the movable plate 35.

[0088] Example 7

[0089] To separate impurity ions from wastewater, a mixture of reagents is used for flocculation, followed by solid-liquid separation to extract these ions, thus simultaneously purifying the wastewater. Please refer to [link / reference needed]. Figure 1-6 As shown, a recycling device for photovoltaic production includes: a liquid delivery pipe 1, a sedimentation tank 2, and a mixing structure 3, wherein the liquid delivery pipe 1 is connected to the mixing structure 3, the bottom of the liquid delivery pipe 1 is connected to the sedimentation tank 2 through a pressurization pipe 7, and an overflow hole 8 is provided on one side of the sedimentation tank 2.

[0090] The mixing structure 3 includes a mixing tank 31. A screw 38 is vertically installed at the center of the bottom inner wall of the mixing tank 31. The outer side of the screw 38 is provided with an external thread. A threaded hole is provided at the center of the rotating disk 39. The rotating disk 39 is rotatably installed on the outside of the screw 38. The threaded hole wall of the rotating disk 39 is clearance-fitted with the external thread surface of the screw 38. When the rotating disk 39 is pushed to move up and down, the inner wall of the rotating disk 39 can rotate and slide along the outer wall of the screw 38. Under the guidance of the external thread of the screw 38, the rotating disk 39 can simultaneously achieve rotation operation during the up and down movement.

[0091] A bearing is installed on the top side of the rotating disk 39, and the rotating disk 39 is connected to the outer ring of the bearing. A fixed disk 36 is installed on the bearing, and the fixed disk 36 is connected to the inner ring of the bearing. The fixed disk 36 serves as the upper and lower force-bearing structure. The fixed disk 36 and the rotating disk 39 are connected by the bearing. During the synchronous up and down movement of the fixed disk 36 and the rotating disk 39, the rotating disk 39 rotates relative to the fixed disk 36, so that the rotating disk 39 can rotate along the external thread structure of the screw 38. This ensures the stability of the force on the rotating disk 39 and prevents motion interference during connection.

[0092] Four connecting rods 310 are vertically fixed at a 90° angle on the top side of the fixed disk 36. A stirring rod 37 is fixed on the outer side of the rotating disk 39. The stirring rod 37 is fixed by a cross-shaped cross of horizontal and vertical rods. The middle part of the stirring rod 37 is connected to the outer side of the rotating disk 39. The stirring rod 37 has a cross-shaped frame structure. When the rotating disk 39 rotates up and down, it drives the stirring rod 37 to rotate up and down. When the rotating disk 39 moves downward, the rotating disk 39 and the stirring rod 37 rotate downward synchronously. The stirring area of ​​the stirring rod 37 is located at the lower part of the mixing tank 31. When the rotating disk 39 moves upward, the rotating disk 39 and the stirring rod 37 rotate upward synchronously. The stirring area of ​​the stirring rod 37 is located at the upper part of the mixing tank 31. During the upward or downward movement of the rotating disk 39, the rotation direction of the rotating disk 39 is opposite, which can drive the stirring rod 37 to stir the mixture at different shear angles, so that the fed mixed drugs and waste liquid can better fuse and react.

[0093] The top ends of the four connecting rods 310 are synchronously fixed with movable discs 35. The movable discs 35 are located inside the mixing tank 31. The outer circumferential surface of the movable discs 35 is fitted with the inner circumferential wall of the mixing tank 31 with a clearance. The vertical sliding distance of the movable discs 35 is the same as the vertical rotation distance of the 39. When the movable discs 35 are subjected to vertical traction force, they can slide inside the mixing tank 31. During the sliding process, they can drive the fixed discs 36 to move up and down, thereby realizing the forward and reverse rotation operation of the rotating discs 39. With the cooperation of the stirring rods 37, the mixture is stirred, and the mixing effect of the drug and waste liquid is improved.

[0094] The mixing structure 3 also includes a mounting plate 315. A lifting motor 317 is fixed to the top center of the mounting plate 315. A rotating disk 316 is mounted on the output shaft of the lifting motor 317. A pull rod 32 is connected to the eccentric point of the rotating disk 316 via a pin. The top of the pull rod 32 is located at the eccentric position of the rotating disk 316. During the rotation of the rotating disk 316, the top of the pull rod 32 can be driven to deflect up and down, so that the pull rod 32 generates a height difference during the movement. A connecting seat 33 is fixed to the top side of the fixed disk 36. The bottom end of the pull rod 32 is connected to the connecting seat 33 via a pin. Under the action of the rotating disk 316, the pull rod 32 generates a height difference. Under the traction of the pull rod 32, the connecting seat 33 moves up and down, so that the mounting plate 315 connected to the bottom side of the connecting seat 33 moves up and down.

[0095] In use, after the waste liquid mixed with the reaction drug is discharged into 31, operation 317 drives 316 to rotate. During the rotation of the rotating disk 316, the top of the pull rod 32 deflects up and down, causing the pull rod 32 to have a height difference during the movement. When the movable disk 35 is subjected to the vertical traction force, it can slide inside the mixing tank 31. During the sliding process, it can drive the fixed disk 36 to move up and down. The fixed disk 36 serves as the vertical force-bearing structure. The fixed disk 36 and the rotating disk 39 are connected by bearings. During the synchronous vertical movement of the fixed disk 36 and the rotating disk 39, the rotating disk 39 rotates relative to the fixed disk 36, allowing the rotating disk 39 to rotate along the external thread structure of the screw 38. Due to the stirring rod 3... The frame structure is cross-shaped. When the rotating disk 39 rotates up and down, it drives the stirring rod 37 to rotate up and down as well. When the rotating disk 39 moves downward, the rotating disk 39 and the stirring rod 37 rotate downward synchronously. The stirring area of ​​the stirring rod 37 is located at the lower part of the mixing tank 31. When the rotating disk 39 moves upward, the rotating disk 39 and the stirring rod 37 rotate upward synchronously. The stirring area of ​​the stirring rod 37 is located at the upper part of the mixing tank 31. During the upward or downward movement of the rotating disk 39, the rotation direction of the rotating disk 39 is opposite, which can drive the stirring rod 37 to stir the mixture at different shear angles. This allows the fed mixed drugs and waste liquid to better fuse and react, and can achieve the precipitation and separation of impurity ions in the waste liquid.

[0096] The movable disk 35 has a ring-shaped array of flow guide holes 34 inside. A support rod 312 is installed inside each flow guide hole 34. The diameter of the support rod 312 is smaller than the inner diameter of the flow guide hole 34. There is a flow gap between the support rod 312 and the flow guide hole 34. A cover plate 314 is fixed to the top of the support rod 312, and a buoyancy plate 311 is fixed to the bottom of the support rod 312. The diameters of the buoyancy plate 311 and the cover plate 314 are larger than the diameter of the flow guide hole 34. The buoyancy plate 311 can be lifted by the buoyancy force below. Combined with the movable disc 35, it forms an integral pressing structure. The buoyancy of the buoyancy plate 311 is greater than the weight of the cover plate 314. After the waste liquid and the medicine are mixed, in order to achieve a better mixing effect, when the movable disc 35 moves downward, since the bottom of the mixing tank 31 is full of mixed liquid, when the movable disc 35 descends, the buoyancy plate 311 blocks the bottom port of the guide hole 34 under the action of buoyancy. With the cooperation of the movable disc 35 and the buoyancy plate 311, the entire pressing surface can be completed, similar to the action of a piston, squeezing out the mixed liquid.

[0097] After the movable disc 35 is pushed down, as the movable disc 35 rises, the buoyancy plate 311 is no longer supported by buoyancy. Under its own weight and the weight of the cover plate 314 and the support rod 312, it separates from the lower end of the guide hole 34, so that the upper and lower spaces of the movable disc 35 are in a through state through the guide hole 34. The mixed liquid can enter the lower part of the movable disc 35 from the top through the guide hole 34 to carry out mixing and stirring operations. The pushing operation can be achieved without affecting the normal feeding.

[0098] The bottom side of the cover plate 314 is fixed with support protrusions 313 in a ring array, which can prevent the cover plate 314 from sealing the upper port of the guide hole 34 when the buoyancy plate 311 is not pushed by the buoyancy below. The length of the support protrusions 313 is less than the thickness difference between the support rod 312 and the movable plate 35, ensuring that there is a good liquid flow space in the upper and lower space of the movable plate 35.

Among them, the actuating plates 92 located on both sides of the discharge port below the storage hopper 4 are... 2. It also serves as a storage structure. When the actuating plate 92 rotates and passes through the discharge port below the storage hopper 4, the medicine in the storage hopper 4 falls into the gap between the two actuating plates 92. With subsequent rotation, the actuating plate 92 rotates to the position connected to the infusion pipe 1. The medicine mixes with the waste liquid under the flushing of the waste liquid. In this way, as long as the flow rate of the waste in the infusion pipe 1 is maintained, the matching value of the dosage and the waste can be maintained within a reasonable range, and the matching dosage within the appropriate range can be achieved, which can improve the treatment effect of the waste liquid. The infusion pipe 1 is connected to the mixing tank 31, and the connection position of the infusion pipe 1 is located above the limit position of the upward movement of the movable plate 35.
