Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical extraction tank technology, specifically a pharmaceutical extraction tank with a self-cleaning function. Background Technology

[0002] In the modern pharmaceutical industry, extraction tanks are indispensable equipment in the drug extraction and processing process. To ensure drug quality and hygiene safety during production, extraction tanks need to be cleaned regularly to remove residual herbs and impurities. However, traditional extraction tank cleaning methods usually rely on manual labor, which has certain limitations, especially in terms of cleaning effectiveness, efficiency, and saving time and labor costs.

[0003] Traditional extraction tanks are typically cleaned manually, involving disassembly, washing, and disinfection. This process is time-consuming and prone to cross-contamination, making it difficult to effectively guarantee equipment hygiene. Especially in continuous production modes, equipment requires frequent cleaning and maintenance, which not only increases production costs but can also lead to excessive downtime and affect production efficiency. To improve production efficiency and reduce hygiene risks, some pharmaceutical plants have begun to try using automated cleaning equipment. However, most of these are limited to fixed cleaning components or require complex automated cleaning devices. The cleaning operation depends on a certain cleaning cycle and time, making real-time effective cleaning impossible. Operability and cleaning effectiveness are often limited by the cleaning materials and cleaning solutions.

[0004] Therefore, those skilled in the art have provided a pharmaceutical extraction tank with a self-cleaning function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical extraction tank with a self-cleaning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pharmaceutical extraction tank with a self-cleaning function includes a movable frame. The extraction tank body is fixedly installed inside the movable frame via a fixing plate. Support frames are fixedly connected to both sides of the movable frame. A guide rod is fixedly connected to one side of the two support frames. A drive assembly is provided on one side of one of the support frames. An adjustment frame is slidably connected to the outer wall of the guide rod. Mounting plates are fixedly connected to both sides of the adjustment frame. A cylinder is fixedly installed on the top of one mounting plate. A sealing cover is fixedly connected to the telescopic end of the cylinder. A placement assembly is provided at the bottom of the sealing cover. An electric telescopic rod is fixedly installed on the other mounting plate via an internal groove. A hollow tube is fixedly connected to the telescopic end of the electric telescopic rod. A connecting cylinder is rotatably connected to the bottom of the hollow tube via a rotary joint. A rotating assembly is provided on the outer wall of the hollow tube. A cleaning disc is fixedly connected to the outer wall of the connecting cylinder. A brushing assembly is provided on the outer wall of the cleaning disc. A spraying assembly is provided at the bottom of the connecting cylinder.

[0008] The mobile frame serves as the basic framework of the equipment, supporting the extraction tank body and the motion mechanism. The two side support structures form a gantry structure, providing rigid support for lateral movement and enabling overall mobility of the equipment, such as cross-station transfer. The double support frame design ensures the stability of the guide rod under high load. During the rising phase, the cylinder pushes the sealing cover and filter basket upwards for easy feeding / covering. During the descending phase, the filter basket is immersed in solvent, the sealing ring engages with the tank opening, and the cylinder continuously applies pressure to form an axial sealing force. A single cylinder synchronously controls immersion and sealing. The electric telescopic rod vertically drives the cleaning components to rise and fall, with the stroke covering the full depth of the tank.

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

[0010] The drive assembly includes a drive motor fixedly mounted on one side of one of the support frames, and a threaded rod is fixedly connected to the output end of the drive motor.

[0011] The outer wall of the threaded rod is threadedly connected to the support frame, and one end of the threaded rod is rotatably connected to another support frame, realizing the switching between two workstations. In the extraction workstation, the filter basket is centered and corresponds to the tank. In the cleaning workstation, the filter basket is moved out of the area above the tank, replacing manual pushing and pulling and shortening the workstation switching time.

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

[0013] The placement assembly includes a drug-dispensing filter basket fixedly installed at the bottom of the sealing cover by four steel plates, and the inner wall of the drug-dispensing filter basket is threaded with a cover plate.

[0014] The container is designed to hold medicinal materials. The filter basket has micropores on its side walls and bottom to allow solvent penetration but intercept medicinal residue. The threaded cover can be locked after feeding to prevent the medicinal materials from floating.

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

[0016] The rotating assembly includes a waterproof motor fixedly installed on the outer wall of the hollow tube. A pinion is fixedly connected to the output end of the waterproof motor, and an external gear is meshed with the outer wall of the pinion.

[0017] The interior of the external gear disc is fixedly connected to the outer wall of the connecting cylinder, and the rotating assembly ensures that the cleaning disc and the nozzle achieve a uniform cleaning effect during the cleaning process.

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

[0019] The scrubbing assembly includes several cleaning plates fixedly installed on the outer wall of the cleaning disc, and a cleaning brush is fixedly installed on one side of each cleaning plate.

[0020] The cleaning plate is equipped with a nylon cleaning brush that mechanically scrapes the tank wall while rotating, thus removing stubborn stains.

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

[0022] The spraying assembly includes a cross tube fixedly connected to the bottom of the connecting cylinder. The four ports of the cross tube are fixedly connected to annular pipes. The outer wall of the annular pipes and the bottom of the cross tube are both fixedly connected to several nozzles.

[0023] The inner wall of the extraction tank is washed with high-pressure water through a nozzle to ensure that every corner is thoroughly cleaned and to prevent contamination by impurities during the extraction process.

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

[0025] The outer wall of the hollow tube is fixedly connected to a water inlet pipe, and the bottom of the extraction tank body is fixedly connected to a water outlet flange pipe.

[0026] The inlet pipe is used to connect the cleaning solution or water to ensure a water supply; the outlet flange pipe discharges the water after cleaning, keeping the cleaning process smooth and free from contamination.

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

[0028] A sealing ring is fixedly installed at the bottom of the sealing cap, and the groove at the bottom of the sealing ring is adapted to the top edge of the extraction tank body.

[0029] The sealing ring ensures a tight fit between the sealing cap and the extraction tank body, preventing liquid leakage and ensuring the sealing and efficiency of the entire extraction process.

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

[0031] 1. Compared with existing technologies, this pharmaceutical extraction tank with self-cleaning function uses a combination of spray washing components, brush washing components, rotating components and hollow tubes. A waterproof motor drives a pinion gear to drive an external gear disc, which rotates the annular nozzle to spray cleaning fluid.

This enables a comprehensive and uniform cleaning of the inner wall of the extraction tank, ensuring thorough cleaning. At the same time, the electric telescopic rod controls the axial feed of the cleaning disc, and the bottom cross-shaped nozzles provide thorough cleaning of the conical tank bottom without dead angles, solving the problem of insufficient coverage of the conical bottom structure of traditional spray cleaning.

[0032] 2. Compared with existing technologies, this pharmaceutical extraction tank with self-cleaning function uses a combination of drive components, placement components, adjustment frames, and guide rods to control the up-and-down movement of the sealing cover and the dispensing filter basket with cylinders and drive motors. This simplifies the operation process, reduces manual intervention, and greatly improves work efficiency and production automation. Furthermore, when the moving frame moves laterally, workers can simultaneously clean the residue in the dispensing filter basket and activate the cleaning system to treat the inner wall of the tank, thereby shortening the cleaning and maintenance cycle of the equipment and improving the availability and continuity of production.

[0041] Please see Figure 1-6In this embodiment of the present invention, a pharmaceutical extraction tank with a self-cleaning function includes a movable frame 1. The extraction tank body 2 is fixedly installed inside the movable frame 1 via a fixing plate. Support frames 3 are fixedly connected to both sides of the movable frame 1.

A rotating component is located on the outer wall of the hollow tube 10. A cleaning disc 12 is fixedly connected to the outer wall of the connecting cylinder 11, and a brushing component is located on the outer wall of the cleaning disc 12. A spraying component is located at the bottom of the connecting cylinder 11. The mobile frame 1 serves as the basic frame of the equipment, supporting the extraction tank body 2 and its movement. The mechanism, with its two side support frames 3 forming a gantry structure, provides rigid support for lateral movement, enabling overall mobility of the equipment, such as cross-station transfer. The double support frame 3 design ensures the stability of the guide rod 4 under high loads. During the rising phase, the cylinder 7 pushes the sealing cover 8 and filter basket upwards for easy feeding / covering. During the descending phase, the filter basket is immersed in solvent, the sealing ring 27 engages with the tank opening, and the cylinder 7 continuously applies pressure to form an axial sealing force. A single cylinder 7 synchronously controls immersion and sealing. The electric telescopic rod 9 vertically drives the cleaning components to rise and fall, covering the full depth of the tank. Through the spray washing components and brushes... The combined use of the washing components, rotating components, and hollow tube 10, etc., drives the small gear 18 through the waterproof motor 17 to drive the external gear disc 19, causing the annular nozzle 24 to rotate and spray cleaning fluid. Simultaneously, the cleaning brush 21 scrapes the tank wall to remove drug residue, thereby enabling a comprehensive and uniform cleaning of the inner wall of the extraction tank, ensuring a thorough cleaning effect. At the same time, the electric telescopic rod 9 controls the axial feed of the cleaning disc 12, combined with the bottom cross-shaped nozzle 24 to rinse the bottom of the conical tank without dead angles, solving the problem of insufficient coverage of the conical bottom structure tank by traditional spray cleaning.

[0042] The drive assembly includes a drive motor 13 fixedly installed on one side of one of the support frames 3. The output end of the drive motor 13 is fixedly connected to a threaded rod 14. The outer wall of the threaded rod 14 is threadedly connected to the support frame 3.

In the extraction workstation, the filter basket is centered and corresponds to the tank. In the cleaning workstation, the filter basket is moved out of the area above the tank, replacing manual pushing and pulling and shortening the workstation switching time.

[0043] The placement assembly includes a medicine-dispensing filter basket 15 fixedly installed at the bottom of the sealing cover 8 by four steel plates. The inner wall of the medicine-dispensing filter basket 15 is threadedly connected to a cover plate 16. The placement assembly is a medicine container. The side wall / bottom of the filter basket is provided with micropores to allow solvent penetration but intercept medicine residue. The threaded cover plate 16 can be locked after feeding to prevent the medicine from floating.

[0044] The rotating assembly includes a waterproof motor 17 fixedly installed on the outer wall of the hollow tube 10. A pinion 18 is fixedly connected to the output end of the waterproof motor 17. An external gear 19 is meshed with the outer wall of the pinion 18. The interior of the external gear 19 is fixedly connected to the outer wall of the connecting cylinder 11. The rotating assembly ensures that the cleaning disc 12 and the nozzle 24 achieve a uniform cleaning effect during the cleaning process.

[0045] The scrubbing assembly includes several cleaning plates 20 fixedly installed on the outer wall of the cleaning plate 12. A cleaning brush 21 is fixedly installed on one side of the cleaning plate 20. The cleaning plate 20 is equipped with a nylon cleaning brush 21, which can mechanically scrape the tank wall during rotation, thereby cleaning stubborn stains. The spray washing assembly includes a cross tube 22 fixedly connected to the bottom of the connecting cylinder 11. The four ports of the cross tube 22 are fixedly connected to annular pipes 23. Several nozzles 24 are fixedly connected to the outer wall of the annular pipes 23 and the bottom of the cross tube 22. The nozzles 24 are used to perform high-pressure water washing on the inner wall of the extraction tank body 2 to ensure that every corner is thoroughly cleaned and to avoid contamination by impurities during the extraction process.

[0046] The outer wall of the hollow tube 10 is fixedly connected to a water inlet pipe 25, and the bottom of the extraction tank body 2 is fixedly connected to a water outlet flange pipe 26. The water inlet pipe 25 is used to connect to the cleaning solution or water to ensure water supply; the water outlet flange pipe 26 discharges the water after cleaning, keeping the cleaning process smooth and pollution-free. A sealing ring 27 is fixedly installed at the bottom of the sealing cover 8. The groove at the bottom of the sealing ring 27 is adapted to the top edge of the extraction tank body 2. The sealing ring 27 ensures a tight fit between the sealing cover 8 and the extraction tank body 2, preventing liquid leakage and ensuring the sealing and efficiency of the entire extraction process.

[0047] The working principle of this utility model is as follows: First, connect the device to an external power source. Then, start the cylinder 7 to extend and retract its telescopic end, causing the sealing cover 8 and the medicine-dispensing filter basket 15 to move upwards synchronously. The operator can then place the medicinal materials to be extracted into the medicine-dispensing filter basket 15, and then rotate the cover plate 16 to fix it in place. At this time, water is injected into the extraction tank body 2, and then the cylinder 7 is started to retract, submerging the medicinal materials in the medicine-dispensing filter basket 15 in the water. Simultaneously, the cylinder 7 will drive the sealing cover 8 to move downwards, so that the sealing ring 27 is aligned with the edge of the extraction tank body 2. Interlocking and connected, the stable thrust of cylinder 7 causes the sealing ring 27 to be press-fitted with the edge of the extraction tank body 2, ensuring a sealed extraction process. After extraction, cylinder 7 can be activated to retract, causing the sealing cover 8 and the medicine filter basket 15 to move upward synchronously. Then, the drive motor 13 is activated, causing its output end to drive the threaded rod 14 to rotate. Under the limit of guide rod 4, the adjusting frame 5 moves laterally. At this time, it is convenient for the staff to remove the extracted medicinal residue, and it is also convenient for the staff to clean up, which facilitates the subsequent extraction operation.

[0048] Furthermore, when the staff cleans the residue in the medicine filter basket 15, the previously moved adjustment frame 5 moves the electric telescopic rod 9 to the upper position of the extraction tank body 2. Then, the staff connects the water inlet pipe 25 to the cleaning solution or clean water through the water pump, and then drives the electric telescopic rod 9 to move its telescopic end downward, simultaneously moving the hollow pipe 10 and the cleaning disc 12. When the nozzle 24 is located on the inner wall of the extraction tank body 2, the water pump starts to make the nozzle 24 spray water to clean the inner wall of the extraction tank body 2. At the same time, the waterproof motor 17 is started, and its output end rotates to drive the pinion 18 to rotate, causing the meshing external gear disc 19 to rotate. This allows the connecting cylinder 11 to rotate under the action of the rotary joint, driving the cleaning disc 12 and the nozzle 24 on the annular pipe 23 to rotate, evenly cleaning the inner wall of the extraction tank body 2. The inner wall of the extraction tank body 2 is cleaned, and the rotation of the cleaning disc 12 will drive the cleaning disc 12 to rotate, so that during the cleaning process of the nozzle 24, the cleaning brush 21 simultaneously scrubs the inner wall of the extraction tank body 2 to ensure the cleaning effect. Then, the staff starts the electric telescopic rod 9 to slowly extend and retract, thereby thoroughly cleaning the extraction tank body 2. When the bottom is cleaned, the nozzle 24 on the cross tube 22 rinses the conical surface at the bottom of the extraction tank body 2, making the cleaning effect better. Then the cleaning water flows out through the outlet flange pipe 26 into the connected recovery pipe, thus completing the cleaning of the tank. After cleaning, the medicine discharge filter basket 15 is also cleaned by the staff. At this time, the drive motor 13 is controlled to rotate in reverse, so that the medicine discharge filter basket 15 is above the extraction tank body 2, and the extraction process can continue, improving production efficiency.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
