Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical intermediates technology, and in particular to a device for removing impurities from pharmaceutical intermediates. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis. During the production of pharmaceutical intermediates, impurities may be present. For example, liquid pharmaceutical intermediates may contain solid impurities. In this case, a filter box is needed for filtration. The filter box is equipped with filter plates. When the worker opens the filter box and pours in the mixture, the solid impurities are blocked by the filter plates. The filtered material flows out from the outlet at the bottom of the box, completing the impurity removal process. However, as the amount of filtered material increases, the amount of impurities accumulated on the filter plates also increases. The accumulation of impurities in any part of the filter plate can affect the filtration efficiency. If the filter plates are frequently disassembled to avoid affecting the filtration effect, it will affect the work efficiency of the workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pharmaceutical intermediate impurity removal device, which solves the technical problem that the accumulation of impurities on the filter plate affects the filtration efficiency of the filter plate, and that frequent disassembly of the filter plate to avoid affecting the filtration effect would affect the work efficiency of the staff.

[0005] Technical solution

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

[0007] A device for removing impurities from pharmaceutical intermediates includes a filter box, wherein a filtration mechanism is provided inside the filter box.

[0008] The filtration mechanism includes a filter plate, a fixing plate, a fixing groove, a connecting plate, and a filter box;

[0009] There are two filter plates, which are fixedly installed on both sides inside the filter box. There are also two fixing plates, which are fixedly installed on both sides inside the filter box. There are two fixing slots, which are respectively opened inside the two fixing plates. There are also two connecting plates, which are respectively snapped into the two fixing slots. The two ends of the filter box are respectively fixedly connected to the ends of the two connecting plates that are away from the fixing slots.

[0010] The two fixing plates are located between the two filter plates, and the two ends of the filter box away from the connecting plate are respectively attached to the two filter plates.

[0011] The filter box has a long plate at the end away from the connecting plate, and a handle is fixedly installed on the outside of the long plate.

[0012] Each of the fixed slots is internally fixedly connected to a spring, each spring is externally fixedly connected to a limiting plate, and a clamping plate is fixedly installed at the end of each connecting plate away from the filter box.

[0013] The limiting plate and the connecting plate are attached together.

[0014] Each of the aforementioned fixed slots has a limiting slot inside, and each limiting plate has a limiting block fixedly installed on its exterior;

[0015] The limiting block is slidably connected inside the limiting groove.

[0020] Beneficial effects

[0021] 1. The filter box, along with the filter plates installed inside, allows material to enter the filter box. Solid impurities in the material are blocked by the filter plates and box, while liquid material passes through them to the outlet, completing the impurity removal process. Since both filter plates are fixedly installed at an angle inside the filter box, the material flows towards the filter box as it is filtered. Solid impurities on the filter plates flow towards the filter box along with the material. Simultaneously, the filter box also filters the material. After the process is complete, pulling the filter box upwards releases the connection between the connecting plate and the fixing groove, allowing the filter box to be removed from the filter box. Impurities on the inner wall of the filter box are then emptied, reducing the area occupied by solid impurities on the filter mechanism, minimizing the impact of solid impurities on the filtration effect, and reducing the number of times the filter mechanism needs to be disassembled, thus avoiding impacting worker efficiency.

[0022] 2. Using the handle located on the outside of the long plate, along with the threaded rod, when the filter box is taken out, turn the handle to rotate it out of the placement slot. At this time, the handle can be pulled upward to release the locking between the connecting plate and the fixing slot, making it easier to pull the filter box. If the handle is damaged, take out the filter box. At this time, the threaded rod will disconnect the connection between the threaded rod and the threaded hole. The handle makes it easy to pull the filter box and also makes it easy to disassemble the damaged handle. Attached Figure Description

[0030] This application provides a pharmaceutical intermediate impurity removal device, which effectively solves the technical problem that the increased accumulation of impurities on the filter plate 2, which affects the filtration efficiency of the filter plate 2 due to the accumulation of impurities at any point on the filter plate 2, and the frequent disassembly of the filter plate 2 to avoid affecting the filtration effect, would affect the work efficiency of the staff.

[0031] Example

[0032] The technical solution in this application embodiment effectively solves the problem that the increased accumulation of impurities on the filter plate 2, and the fact that the accumulation of impurities at any point on the filter plate 2, affects the filtration efficiency of the filter plate 2, and that frequent disassembly of the filter plate 2 to avoid affecting the filtration effect would affect the work efficiency of the staff. The overall idea is as follows:

[0033] To address the problems existing in the prior art, this utility model provides a pharmaceutical intermediate impurity removal device, which includes a filter box 1, and a filter mechanism is provided inside the filter box 1.

[0034] The filtration mechanism includes a filter plate 2, a fixing plate 3, a fixing groove 4, a connecting plate 5, and a filter box 6;

[0035] There are two filter plates 2, which are fixedly installed on both sides inside the filter box 1. There are two fixing plates 3, which are fixedly installed on both sides inside the filter box 1. There are two fixing grooves 4, which are respectively opened inside the two fixing plates 3. There are two connecting plates 5, which are respectively snapped into the two fixing grooves 4. The two ends of the filter box 6 are respectively fixedly connected to the ends of the two connecting plates 5 away from the fixing grooves 4.

[0036] Among them, the two fixing plates 3 are located between the two filter plates 2, and the filter box 6 is attached to the two filter plates 2 at both ends away from the connecting plate 5.

[0037] By using filter plates 2 and filter boxes 6 installed inside filter box 1, when material enters the filter box 1, it comes into contact with filter plates 2 and filter boxes 6. Solid impurities in the material are blocked by filter plates 2 and filter boxes 6, while liquid material passes through filter plates 2 and filter boxes 6 to the outlet, completing the impurity removal process. Since both filter plates 2 are installed at an angle and fixed inside filter boxes 6, the material flows towards filter boxes 6 while being filtered by filter plates 2. At this time, solid impurities on filter plates 2 flow towards filter boxes 6 with the material flow. Simultaneously, filter boxes 6 also filter the material. After the work is completed, pull filter boxes 6 upward to release the engagement between connecting plate 5 and fixing groove 4, remove filter boxes 6 from the inside of filter box 1, and pour out the impurities on the inner wall of filter boxes 6. This reduces the area occupied by fixed impurities on the filter mechanism, reduces the impact of solid impurities on the filtration effect of the filter mechanism, and reduces the number of times the filter mechanism needs to be disassembled by the operator, thus avoiding affecting the operator's work efficiency.

[0038] A long plate 7 is provided at the end of the filter box 6 away from the connecting plate 5. A handle 8 is fixedly installed on the outside of the long plate 7 to facilitate pulling the filter box 6.

[0039] Each fixed slot 4 is internally fixedly connected to a spring 9, each spring 9 is externally fixedly connected to a limiting plate 10, and each connecting plate 5 is fixedly installed with a clamping plate 11 at the end away from the filter box 6.

[0040] The limiting plate 10 is attached to the connecting plate 5 to facilitate the reinforcement of the connection between the connecting plate 5 and the fixing groove 4.

[0041] Each fixed slot 4 has a limiting slot 12 inside, and each limiting plate 10 has a limiting block 13 fixedly installed on the outside;

[0042] The limiting block 13 is slidably connected inside the limiting groove 12, limiting the position of the limiting plate 10, so that the card plate 11 can enter the interior of the fixing groove 4.

[0043] The long plate 7 has a placement groove 14 on its outside, and a fixed shaft 15 is rotatably connected inside the placement groove 14;

[0044] The handle 8 is fixedly installed on the outside of the fixed shaft 15, which facilitates the rotation and placement of the handle 8.

[0045] The filter box 6 has a threaded hole 16 on the side near the long plate 7. The end of the long plate 7 away from the fixed shaft 15 is rotatably connected to a threaded rod 17, which is rotatably connected inside the threaded hole 16.

[0046] The threaded rod 17 consists of a threaded rod 17 body and a cuboid plate, which facilitates the disassembly of the damaged handle 8.

[0047] By using the handle 8 located on the outside of the long plate 7 and the threaded rod 17, when the filter box 6 is taken out, the handle 8 is turned to rotate and move out of the placement groove 14. At this time, the handle 8 can be pulled upward to release the engagement between the connecting plate 5 and the fixing groove 4, making it easier to pull the filter box 6. If the handle 8 is damaged, the filter box 6 can be taken out. At this time, the threaded rod 17 will disconnect the connection between the threaded rod 17 and the threaded hole 16. The handle 8 makes it easy to pull the filter box 6 and also makes it easy to disassemble the damaged handle 8.

[0048] Working principle:

[0049] When the material enters the filter box 1, it comes into contact with the filter plate 2 and the filter box 6. Solid impurities in the material are blocked by the filter plate 2 and the filter box 6, while liquid material flows through the filter plate 2 and the filter box 6 to the outlet. Since both filter plates 2 are installed at an angle and fixed inside the filter box 6, the material flows towards the filter box 6 as it is filtered by the filter plate 2. Solid impurities on the filter plate 2 flow towards the filter box 6 along with the material flow. Simultaneously, the filter box 6 also filters the material. After the work is completed, the handle 8 is rotated to move it out of the placement slot 14. Inside the filter box 1, pull the handle 8 to move the filter box 6, causing the connecting plate 5 to disengage from the fixing groove 4. At this time, under the action of the spring 9, the limiting plate 10 returns to its original position. The filter box 6 is then removed from the inside of the filter box 1, and the impurities on the inner wall of the filter box 6 are poured out. The filter box 6 is then placed back into the filter box 1. At this time, the locking plate 11 enters the fixing groove 4. Under the action of the shape of the locking plate 11, the limiting plate 10 moves. At this time, the spring 9 is compressed until the connecting plate 5 is locked inside the fixing groove 4. At this time, the connecting plate 5 is in contact with the limiting plate 10, and the filter box 6 is fixed, allowing for filtration again.

[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
