Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a plate and frame filter for veterinary drug preparation. Background Technology

[0002] In the process of veterinary drug preparation, plate and frame filter presses are key equipment widely used for solid-liquid separation. They use filter cloth to trap solids (such as drug residue, active ingredient aggregates, etc.) in the drug solution to improve the purity of the drug solution.

[0003] For example, Chinese utility model patent application number 202323125345.3 discloses a plate and frame filter press for veterinary drug preparation. Addressing the problem that existing equipment easily produces residue adhering to the filter cloth during material feeding, leading to reduced cleaning efficiency, the following solution is proposed: The filter press includes a filter press with four telescopic rods bolted to its bottom corners. Each of the four telescopic rods has a connecting cylinder inserted into its bottom end. Each of the four connecting cylinders has a buffer spring screwed into its bottom end. The tops of the four buffer springs are screwed into the bottom ends of the corresponding telescopic rods. Each of the four connecting cylinders has a base plate welded to its bottom end. Each of the four base plates has a through-hole at its four corners. A vibration motor is bolted to the front of the filter press. This utility model, through the cooperation of the vibration motor and buffer springs, controls the filter press to vibrate up and down, effectively shaking off impurities adhering to the filter cloth and improving cleaning efficiency.

[0004] Traditional plate and frame filters require the filter plates to be loosened one by one for unloading, which is cumbersome and time-consuming. In continuous production, the unloading operation takes up a lot of time, resulting in low production efficiency. Moreover, the residual residue on the filter cloth and filter plate surface can easily clog the mesh, requiring frequent disassembly and cleaning. Existing cleaning devices are mostly fixed nozzles, which are difficult to cover the entire surface of the filter plate and lack mechanical brushing function, resulting in poor cleaning effect.

[0005] Therefore, there is an urgent need for a plate and frame filter press for veterinary drug preparation that can improve efficiency during unloading and cleaning, reduce manual operation and maintenance costs, and ensure efficient cleaning of the equipment to guarantee filtration effect. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plate and frame filter for veterinary drug preparation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a plate and frame filter for veterinary drug preparation, comprising a filter frame, a plurality of plate frames slidably connected to the top of the filter frame, a pressing assembly provided on the front of the filter frame, fixed cylinders fixedly connected to both sides of the plate frames, a chain movably fitted on the outer wall of every two fixed cylinders, a fixing assembly provided on the fixed cylinder, electric slide rails fixedly connected to both sides of the filter frame, support columns slidably connected inside the electric slide rails via electric sliders, electric telescopic rods fixedly connected to the opposite sides of two support columns, a support plate fixedly connected to the telescopic ends of two electric telescopic rods, four suspension plates fixedly connected to the bottom of the support plate, a hollow block fixedly connected to one side of every two suspension plates, a water inlet assembly provided on the opposite side of two hollow blocks, two fixed plates fixedly connected to the bottom of the hollow block, a roller brush rotatably connected between the opposite sides of two fixed plates, and a drive assembly provided at the bottom of the support plate.

[0008] The filter frame, as the main frame of the equipment, provides support for the sliding, squeezing, and cleaning mechanisms of the filter plates and frames. Internal sliding rail channels ensure stable movement of the filter plates and frames. The core filter unit of the filter plates and frames contains filter cloth and achieves solid-liquid separation through hydraulic squeezing. Fixed cylinders on both sides are connected to chains, forming a linked unloading structure. The chains are detachable hinged chains that transmit tension to achieve linked separation of the filter plates and frames. After unfolding, a continuous cleaning channel is formed. Electric sliding rails drive the cleaning mechanism laterally, covering the entire filter plate and frame. Electric telescopic rods vertically adjust the height of the cleaning components, ensuring precise contact between the nozzles and roller brushes with the filter plate and frame surface. The hollow block integrates water channels, distributing high-pressure water to the nozzles. Simultaneously, roller brushes are installed via fixed plates. The roller brushes are a composite structure of nylon bristles and a rubber spindle, using rotational mechanical brushing to remove stubborn residue from the filter cloth surface.

[0009] As a further description of the above technical solution:

[0010] The fixing component is threadedly connected to a threaded rod at one end of the fixing cylinder, and a blocking disc is fixedly connected to one end of the threaded rod.

[0011] The threaded rod is screwed into the end of the fixed cylinder to fix the position of the chain, and the blocking plate prevents the chain from coming out. After disassembly, it is easy to adjust the number of plates and frames.

[0012] As a further description of the above technical solution:

[0013] The water inlet assembly includes a copper pipe fixedly connected to one side of two hollow blocks, and a water inlet pipe is fixedly connected to the outer wall of the copper pipe.

[0014] The copper pipes are corrosion resistant and introduce external water into the hollow block. The water inlet pipe is connected to a water pump to provide high-pressure water flow.

[0015] As a further description of the above technical solution:

[0016] The drive assembly includes a servo motor and a fixed frame. The servo motor is fixedly mounted on the bottom of the support plate, and the fixed frame is fixedly mounted on one side of one of the suspension plates. A drive shaft is rotatably connected inside the fixed frame.

[0017] The servo motor is the power source, driving the synchronous gear and the small synchronous gear, and transmitting power to the double-sided roller brush through the synchronous belt.

[0018] As a further description of the above technical solution:

[0019] The output end of the servo motor and the outer wall of the drive shaft are both fixedly connected to small synchronous gears, and the outer walls of the two small synchronous gears are connected by a synchronous belt drive.

[0020] A small synchronous gear connects the output of the servo motor to the drive shaft, enabling a single motor to drive two roller brushes.

[0021] As a further description of the above technical solution:

[0022] The output end of the servo motor and one end of one of the roller brushes penetrating the fixed plate are fixedly connected to a synchronous gear one. The outer wall of the drive shaft and one end of the other roller brush penetrating the fixed plate are fixedly connected to a synchronous gear two. The outer walls of the two synchronous gears one are connected by a synchronous belt drive, and the outer walls of the two synchronous gears two are also connected by a synchronous belt drive.

[0023] Synchronous gear one and synchronous gear two drive the same-side roller brush and the opposite-side roller brush respectively to ensure synchronous brushing on both sides.

[0024] As a further description of the above technical solution:

[0025] The extrusion assembly includes a hydraulic cylinder fixedly mounted on the front of the filter frame, and a push plate is fixedly connected to the telescopic end of the hydraulic cylinder.

[0026] The hydraulic cylinder provides the power source and pushes the push plate through the telescopic end to apply uniform pressure to the plate frame, ensuring efficient filtration of the medicine. The push plate transmits hydraulic pressure to the plate frame stacking surface, pressing the filter cloth to form a sealed cavity to prevent medicine leakage.

[0027] As a further description of the above technical solution:

[0028] Several nozzles are fixedly installed on one side of each of the two hollow blocks.

[0029] The nozzles are fan-shaped, evenly covering both sides of the plate frame to rinse away residual medicine residue. The nozzles are evenly spaced to ensure no dead corners are covered.

[0030] This utility model has the following beneficial effects:

[0031] 1. Compared with existing technologies, this plate and frame filter press for veterinary drug preparation, through the coordinated use of drive components, water inlet components, hollow blocks, and roller brushes, enables the automatic movement of the support plate, suspension plate, and hollow blocks via the cooperation of electric slide rails and electric telescopic rods. The activation of the spray nozzles and servo motors allows for effective spraying and rinsing of the plate and frame. Furthermore, the rotation of the roller brushes driven by the servo motors further cleans both sides of the plate and frame, thereby achieving automatic cleaning of the plate and frame. This ensures that drug residues and contaminants are thoroughly removed, greatly improving cleaning efficiency and reducing manual intervention.

[0032] 2. Compared with existing technologies, this plate and frame filter press for veterinary drug preparation uses a combination of fixed components, plates and frames, fixed cylinders, and chains to connect the plates and frames via detachable chains. Only the first plate and frame needs to be pulled to simultaneously separate all filter plates, significantly improving the unloading speed and greatly reducing the intensity of manual operation. The chain module supports quick disassembly and reassembly, and the number of plates and frames can be increased or decreased according to actual needs to flexibly adapt to different batch production scales. At the same time, after the plates and frames are unfolded, they form an unobstructed channel, which can be directly rinsed or mechanically brushed to remove residual drug residues, avoiding the cumbersome process of traditional disassembly piece by piece and reducing downtime.

The electric slide rail 5 drives the cleaning mechanism to move laterally, covering the entire plate frame 2. The electric telescopic rod 7 vertically adjusts the height of the cleaning components, ensuring that the nozzle 23 and roller brush 12 precisely fit the surface of the plate frame 2. The hollow block 10 integrates a water channel, distributing high-pressure water to the nozzle 23. Simultaneously, the roller brush 12 is installed via the fixed plate 11.

Furthermore, the rotation of roller brush 12 driven by servo motor 17 further cleans the two sides of the plate frame 2, thereby realizing the automatic cleaning of the plate frame 2, ensuring that drug residue and residue are cleaned, greatly improving cleaning efficiency and reducing manual intervention.

[0044] The fixed component is threaded to a threaded rod 13 at one end of the fixed cylinder 3. A blocking disc 14 is fixedly connected to one end of the threaded rod 13. The threaded rod 13 is screwed into the end of the fixed cylinder 3 to fix the position of the chain 4. The blocking disc 14 prevents the chain 4 from coming out. After disassembly, it is easy to adjust the number of plate frames 2.

[0045] The water inlet assembly includes a copper pipe 15 fixedly connected to one side of two hollow blocks 10. The outer wall of the copper pipe 15 is fixedly connected to a water inlet pipe 16. The copper pipe 15 is corrosion resistant and introduces external water into the hollow block 10. The water inlet pipe 16 is connected to a water pump to provide high-pressure water flow.

[0046] The drive assembly includes a servo motor 17 and a fixed frame 18. The servo motor 17 is fixedly installed at the bottom of the support plate 8, and the fixed frame 18 is fixedly installed on one side of one of the suspension plates 9. The drive shaft 19 is rotatably connected inside the fixed frame 18. The servo motor 17 is the power source, driving the synchronous gear 21 and the small synchronous gear 20, and transmitting power to the double-sided roller brush 12 through the synchronous belt. The output end of the servo motor 17 and the outer wall of the drive shaft 19 are both fixedly connected to the small synchronous gear 20. The outer walls of the two small synchronous gears 20 are connected by the synchronous belt drive. The small synchronous gear 20 connects the output end of the servo motor 17 and the drive shaft 19, realizing the single motor driving the double roller brush 12.

[0047] The output end of the servo motor 17 and one end of one of the roller brushes 12 that penetrates the fixing plate 11 are fixedly connected to a synchronous gear 21. The outer wall of the drive shaft 19 and one end of the other roller brush 12 that penetrates the fixing plate 11 are fixedly connected to a synchronous gear 22. The outer walls of the two synchronous gears 21 are connected by synchronous belt drive, and the outer walls of the two synchronous gears 22 are also connected by synchronous belt drive. The synchronous gears 21 and 22 drive the roller brushes 12 on the same side and the roller brushes 12 on the opposite side, respectively, to ensure synchronous brushing on both sides.

[0048] The extrusion assembly includes a hydraulic cylinder 24 fixedly installed on the front of the filter frame 1. The telescopic end of the hydraulic cylinder 24 is fixedly connected to a push plate 25. The hydraulic cylinder 24 provides a power source and pushes the push plate 25 through the telescopic end to apply uniform pressure to the plate frame 2, ensuring efficient filtration of the medicine. The push plate 25 transmits hydraulic pressure to the stacking surface of the plate frame 2, pressing the filter cloth to form a sealed cavity to prevent leakage of the medicine.

[0049] Several nozzles 23 are fixedly installed on one side of each of the two hollow blocks 10. The nozzles 23 are fan-shaped nozzles that evenly cover both sides of the plate frame 2 to rinse away residual medicine residue. The nozzles 23 are evenly spaced to ensure no dead corners are covered.

[0050] Working principle: First, connect the device to an external power source, then start the hydraulic cylinder 24, causing its telescopic end to push the push plate 25 to squeeze the plate frame 2, which works in conjunction with the internal filter cloth for filtration. After filtration, the operator can control the telescopic end of the hydraulic cylinder 24 to retract, and then pull the first plate frame 2 that is in contact with the push plate 25. Pulling the plate frame 2 causes the chain 4 of the plate frame 2 to move and tighten, which in turn moves the second plate frame 2. At the same time, the chain 4 on the second plate frame 2 tightens and tightens, moving the third plate frame 2. This allows all the plate frames 2 to be pulled in sequence, achieving the purpose of quickly opening and unloading the material, greatly improving the unloading speed, reducing labor intensity, and increasing production efficiency. At the same time, after the filter frame is unfolded, a continuous cleaning channel is formed, which can directly rinse or brush the residual dregs, reducing the intensity of manual intervention. Furthermore, the chain 4 is detachable to accommodate different numbers of plate frames 2.

[0051] Then, when cleaning is required, the electric slide rail 5 can be activated to synchronously move the support column 6, positioning the two hollow blocks 10 on opposite sides above the frame 2. The water inlet pipe 16 is then connected to the water source. The electric telescopic rod 7 is then activated, causing its telescopic end to move the support plate 8, which in turn moves the suspension plate 9 and the hollow blocks 10. Simultaneously, the spray nozzle 23 and servo motor 17 are activated. The spray nozzle 23 sprays and washes the frame 2, while the servo motor 17 drives one of the small synchronous gears 20 and one of the synchronous gears 21 to rotate synchronously. The rotation of gear 21 drives another synchronous gear 21 to rotate via a synchronous belt, which in turn causes the roller brush 12 to rotate and clean one side of the plate frame 2. At the same time, the rotation of the small synchronous gear 20 drives another small synchronous gear 20 to rotate via a synchronous belt, which in turn drives the drive shaft 19 to rotate and causes the synchronous gear 22 on the drive shaft 19 to rotate. Under the transmission of the synchronous belt, the synchronous gear 22 on the other roller brush 12 rotates, thereby cleaning the other side of the plate frame 2. Then, in conjunction with the raising and lowering of the electric telescopic rod 7, the automatic cleaning of the plate frame 2 is completed.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
