Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a multi-stage sedimentation filtration device for treating veterinary drug production wastewater. Background Technology

[0002] The core purpose of the multi-stage sedimentation and filtration device for treating veterinary drug production wastewater is to remove suspended solids, colloidal particles, and some dissolved impurities from the wastewater through multi-stage physical sedimentation and filtration, thereby reducing the concentration of pollutants in the wastewater and laying the foundation for subsequent advanced treatment or compliance with discharge standards.

[0003] The existing technology has the following problems: The existing equipment cannot replace the filter plates during use. Veterinary drug wastewater contains a large amount of suspended solids, drug residues, and colloidal substances, which easily clog the filter plate pores. When replacement is not possible, only temporary measures such as backwashing can be used, which are difficult to completely clean the blockages. This leads to a slower and slower filtration speed, and may even fail to meet the wastewater treatment requirements. In addition, the existing equipment cannot stir the liquid during filtration. Suspended solids, drug residues, and other solid particles in veterinary drug wastewater are prone to natural sedimentation due to gravity. If not stirred, the particles will accumulate in large quantities at the bottom of the equipment or in local areas above the filter layer, resulting in uneven stress on the filter layer, a slower overall filtration speed, and an inability to quickly complete solid-liquid separation. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-stage sedimentation and filtration device for treating veterinary drug production wastewater, which can effectively solve the problem.

[0005] To achieve the above objectives, the technical solution adopted in this utility model is as follows: A multi-stage sedimentation and filtration device for treating veterinary drug production wastewater includes a filter tank. A feed pipe is fixedly connected to the outer wall of the filter tank, and a discharge pipe is fixedly connected to the lower end of the filter tank. A fixing plate is fixedly connected to the outer wall of the filter tank, and multiple filter plates are movably connected through the outer wall of the filter tank. Multiple snap-fit ​​blocks are fixedly connected to the rear side of the fixing plate. A fixing seat is fixedly connected to the upper side of the inner surface of the filter tank, and a rotating shaft is rotatably connected through the lower side of the fixing seat. Multiple stirring blades are fixedly connected to the outer wall of the rotating shaft, and a motor is fixedly connected to the top of the filter tank.

[0006] Preferably, a slot is provided on the rear side of the filter plate, and a knob is rotatably connected to the rear side of the snap-fit ​​block.

[0007] Preferably, a threaded rod is fixedly connected to the front side of the knob, a threaded ring is threadedly connected to the outer wall of the threaded rod, two connecting rods are fixedly connected to the outer wall of the threaded ring, a movable plate is fixedly connected to the other end of the connecting rod, and a plug is fixedly connected to the front side of the movable plate.

[0008] Preferably, the outer wall of the insertion post is slidably connected to the locking block, the inner surface of the locking block is fixedly connected to a limiting plate, the outer wall of the limiting plate is slidably connected to the moving plate, and the outer wall of the insertion post is movably connected to the slot.

[0009] Preferably, the output end of the motor is fixedly connected to a drive shaft, and the outer wall of the drive shaft is slidably connected to the rotating shaft.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model provides a multi-stage sedimentation and filtration device for treating veterinary drug production wastewater. Through the cooperation of slots, knobs, threaded rods, threaded rings, connecting rods, limiting plates, moving plates, and inserts, the filter plates can be replaced. When the filter plates are blocked by drug residues or suspended solids, or when they are corroded or damaged, they can be directly replaced with brand new or cleaned filter plates without relying on backwashing, which has limited effect. This allows for rapid restoration of filter layer porosity and filtration speed, ensuring that the device continuously meets the requirements for wastewater treatment volume and treatment accuracy. This utility model provides a multi-stage sedimentation and filtration device for treating veterinary drug production wastewater. Through the cooperation of a drive shaft, fixed rod, lifting plate, spring, guide column, motor, fixed ring, annular inclined groove and baffle, the liquid can be stirred during filtration. Stirring can break the natural sedimentation tendency of solid particles, so that they are evenly dispersed in the wastewater, avoiding local accumulation of particles on the top of the filter layer or the bottom of the device. This allows the pores of the filter layer to be used evenly, greatly improving the filtration speed per unit time. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.

[0015] like Figure 1-2 As shown, this utility model provides a multi-stage sedimentation and filtration device for treating veterinary drug production wastewater, including a filter tank 1. A feeding pipe 2 is fixedly connected to the outer wall of the filter tank 1, and a discharge pipe 6 is fixedly connected to the lower end of the filter tank 1. A fixing plate 3 is fixedly connected to the outer wall of the filter tank 1, and multiple filter plates 4 are movably connected through the outer wall of the filter tank 1. Multiple snap-fit ​​blocks 5 are fixedly connected to the rear side of the fixing plate 3. A fixing seat 7 is fixedly connected to the upper side of the inner surface of the filter tank 1, and a rotating shaft 8 is rotatably connected through the lower side of the fixing seat 7. Multiple stirring rods are fixedly connected to the outer wall of the rotating shaft 8. The mixing blade 9 and the top of the filter tank 1 are fixedly connected to a motor 23. Wastewater enters the filter tank 1 through the feeding pipe 2 and flows through multiple filter plates 4 in sequence under the action of gravity. The filter plates 4 achieve preliminary filtration of suspended solids, drug residues and other impurities in the wastewater through physical interception. The filtered wastewater is finally discharged through the discharge pipe 6 at the bottom of the filter tank 1, completing the basic sedimentation filtration process. At the same time, the motor 23 at the top of the filter tank 1 drives the internal stirring structure to operate. With the replaceable filter plates 4, the problems of slow filtration speed and easy clogging of filter plates 4 in traditional devices are solved.

[0016] like Figure 3-4As shown, this utility model provides a technical solution: Preferably, a slot 10 is provided on the rear side of the filter plate 4, a knob 11 is rotatably connected to the rear side of the snap-fit ​​block 5, a threaded rod 12 is fixedly connected to the front side of the knob 11, a threaded ring 13 is threadedly connected to the outer wall of the threaded rod 12, two connecting rods 14 are fixedly connected to the outer wall of the threaded ring 13, a movable plate 16 is fixedly connected to the other end of the connecting rod 14, an insertion post 17 is fixedly connected to the front side of the movable plate 16, the outer wall of the insertion post 17 is slidably connected to the snap-fit ​​block 5, a limiting plate 15 is fixedly connected to the inner surface of the snap-fit ​​block 5, the outer wall of the limiting plate 15 is slidably connected to the movable plate 16, and the insertion post 17... The outer wall is movably connected to the slot 10. When the filter plate 4 needs to be replaced, the knob 11 on the back of the snap-fit ​​block 5 is turned to drive the threaded rod 12 to rotate synchronously. The threaded rod 12 and the threaded ring 13 are engaged by threads, so that the threaded ring 13 moves axially along the threaded rod 12, and then drives the moving plate 16 to move synchronously under the constraint of the limiting plate 15 through the connecting rod 14. The moving plate 16 drives the front insert 17 to disengage from the slot 10 on the back of the filter plate 4, releasing the fixation of the filter plate 4, so that the filter plate 4 can be pulled out from the outer wall of the filter tank 1 for replacement. When installing a new filter plate 4, the knob 11 is turned in the opposite direction to make the insert 17 re-insert into the slot 10, thus completing the fixation of the filter plate 4.

[0017] like Figure 5 As shown, this utility model provides a technical solution: Preferably, the output end of the motor 23 is fixedly connected to a drive shaft 18, the outer wall of the drive shaft 18 is slidably connected to the rotating shaft 8, the outer wall of the rotating shaft 8 is fixedly connected to a lifting plate 20, the outer wall of the drive shaft 18 is fixedly connected to two fixing rods 19, the outer walls of the fixing rods 19 are slidably connected to the lifting plate 20, the outer wall of the fixing rods 19 is fixedly connected to a stop block 26, the outer wall of the fixing rods 19 is sleeved with a spring 21, one end of the spring 21 is fixedly connected to the stop block 26, the other end of the spring 21 is fixedly connected to the lifting plate 20, the outer wall of the lifting plate 20 is fixedly connected to a guide post 22, the lower side of the inner surface of the fixing seat 7 is fixedly connected to a fixing ring 24, the inner surface of the fixing ring 24 is provided with an annular inclined groove 25, the outer wall of the guide post 22 is fixedly connected to the annular groove 25, and the outer wall of the guide post 22 is fixedly connected to the annular groove 25. The inclined groove 25 is slidably connected. When the motor 23 is started, its output end drives the drive shaft 18 to rotate. The drive shaft 18 drives the lifting plate 20 to rotate synchronously through the fixed rod 19. The lifting plate 20 then drives the rotating shaft 8 and the stirring blades 9 on the outer wall to rotate, realizing the initial stirring of the wastewater in the filter tank 1. At the same time, the guide post 22 on the outer wall of the lifting plate 20 slides in the annular inclined groove 25 on the inner surface of the fixed ring 24. The inclined structure of the annular inclined groove 25 forces the guide post 22 to drive the lifting plate 20 to move up and down along the axis of the fixed rod 19. Under the limit of the stop block 26, the spring 21 extends and retracts synchronously with the movement of the lifting plate 20, assisting the lifting plate 20 to reset. Finally, the rotating shaft 8 drives the stirring blades 9 to realize the compound stirring action of "rotation + up and down reciprocating", breaking the natural sedimentation trend of solid particles and avoiding local accumulation.

[0018] The working principle of the multi-stage sedimentation and filtration device for treating veterinary drug production wastewater will be explained in detail below.

[0019] like Figure 1-5 As shown, when the filter plate 4 needs to be replaced, turn the knob 11 on the back of the locking block 5 to drive the threaded rod 12 to rotate synchronously; the threaded rod 12 and the threaded ring 13 are engaged by threads, causing the threaded ring 13 to move axially along the threaded rod 12, and then drive the moving plate 16 to move synchronously under the constraint of the limiting plate 15 through the connecting rod 14; the moving plate 16 drives the front insert 17 to disengage from the slot 10 on the back of the filter plate 4, releasing the fixation of the filter plate 4, so that the filter plate 4 can be pulled out from the outer wall of the filter tank 1 for replacement; when installing the new filter plate 4, turn the knob 11 in the opposite direction to make the insert 17 re-insert into the slot 10, completing the fixation of the filter plate 4, start the motor 23, and its output end drives the drive shaft 18 to rotate, driving The rotating shaft 18 drives the lifting plate 20 to rotate synchronously via the fixed rod 19. The lifting plate 20 then drives the rotating shaft 8 and the stirring blades 9 on the outer wall to rotate, achieving initial stirring of the wastewater in the filter tank 1. At the same time, the guide post 22 on the outer wall of the lifting plate 20 slides in the annular inclined groove 25 on the inner surface of the fixed ring 24. The inclined structure of the annular inclined groove 25 forces the guide post 22 to drive the lifting plate 20 to move up and down along the axis of the fixed rod 19. Under the limit of the stop block 26, the spring 21 extends and retracts synchronously with the movement of the lifting plate 20, assisting the lifting plate 20 to reset. Finally, the rotating shaft 8 drives the stirring blades 9 to achieve a compound stirring action of "rotation + up and down reciprocating", breaking the natural sedimentation trend of solid particles and avoiding local accumulation.
