Description

Technical Field

[0001] This utility model belongs to the technical field of chemical production raw material filtration devices, specifically a clogging-proof chemical production raw material filtration device. Background Technology

[0002] Chemical raw materials are used to produce various chemical products. To ensure product quality, the raw materials need to be filtered using a filtration device before production.

[0003] A search revealed that Chinese patent application number 2024203689886 discloses an anti-clogging chemical production raw material filtration device. It mainly uses a dredging component to unclog the filter holes, and then uses a sweeping and collecting component to clean and collect waste and impurities, thereby achieving the anti-clogging function. This solves the problem that common chemical production raw material filtration devices lack a structure for unclogging the filter structure and cleaning debris, which leads to clogging after a period of use.

[0004] However, when the filter device is in use, after the chemical raw materials are put into the processing box through the feeding hopper, the chemical raw materials will fall directly onto the surface of the filter frame. The filter frame has multiple filter holes inside. After the raw materials fall through the feeding hopper, they fall below the outlet and do not disperse to the surrounding areas. As a result, the raw materials can only be filtered through the filter holes within the range of the bottom of the raw materials. The raw materials are difficult to fall due to the stress generated by their own accumulation, resulting in excessive local accumulation of raw materials, which affects the filtration effect. Summary of the Invention

[0005] The purpose of this invention is to provide a filter device for chemical production raw materials that prevents clogging, thus preventing excessive local accumulation of raw materials that makes it difficult for them to pass through the filter screen.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A filter device for chemical production raw materials that prevents clogging is provided, comprising a housing, a vibration motor mounted on the outer wall of the housing, a turntable fixedly connected to the output end of the vibration motor, a linkage column fixedly connected to the outer wall of the turntable, a vibration box disposed inside the housing, a linkage groove formed on the outer wall of the vibration box, multiple limit rods fixedly connected to the outer wall of the vibration box, a baffle fixedly connected to one end of each limit rod penetrating the housing, a spring fixedly connected to the outer wall of the baffle, and the other end of the spring fixedly connected to the outer wall of the housing, sliding grooves formed on both sides of the inner wall of the vibration box, a filter screen disposed inside the sliding grooves, an installation groove formed on the outer wall of the vibration box, an installation plate fixedly connected to the outer wall of the filter screen, the installation plate being fixedly connected to the inner wall of the installation groove by bolts, a flap movably connected to the inner wall of the vibration box, and a tilting motor mounted on the outer wall of the vibration box, the output end of the tilting motor being fixedly connected to one end of the flap.

[0007] Optionally, the linkage column is located inside the linkage groove, and the mounting plate is located inside the mounting groove.

[0008] Optionally, a collection box is provided inside the bottom of the vibration box. The collection box is fixedly connected by bolts. The collection box includes a fine material bin and a coarse material bin. The outer wall of the collection box has a groove.

[0009] Optionally, the fine material bin is located below the filter screen, and the coarse material bin is located behind the fine material bin.

[0010] Optionally, a fixing rod is fixedly connected to the inner wall of the vibration box, the left outer wall of the fixing rod is tightly fitted to the outer wall of the filter screen, and the top of the fixing rod is tightly fitted to the bottom of the flap.

[0011] Optionally, the bottom of the vibration box is equipped with pulleys, and the number of pulleys is multiple.

[0012] Optionally, the bottom of the outer casing is fixedly connected to a support column, and there are multiple support columns, each of which is threaded with an adjusting foot.

[0013] Optionally, the top of the housing has a communication port, and the top of the housing is fixedly connected to a feed port. The feed port is connected to the housing through the communication port and is located above the filter screen.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the initial state of this utility model, the edge of the flap contacts the edge of the filter screen, and the bottom of the flap is tightly fitted with the top of the fixing rod, forming a sealed space at the top of the filter screen. The vibration motor operates, driving the turntable and its connected linkage column to rotate synchronously. The linkage column moves along the linkage groove on the outer wall of the vibration box as the turntable rotates. Because the linkage column performs circular motion, the vibration box reciprocates synchronously with the linkage column. When the vibration box moves to the left, multiple springs on the left are stretched, while multiple springs on the right are compressed. When the vibration box moves to the right, multiple springs on the right are stretched, while multiple springs on the left are compressed. Since the filter screen is connected to the vibration box by bolts, the outer shell moves synchronously with the vibration box. The vibrating box acts as a vibrating screen, allowing raw materials to enter through the feed inlet and fall onto the upper surface of the filter screen. As the vibrating box reciprocates, the raw materials on the filter screen are dispersed. Materials already on the screen are forced through due to the reciprocating movement of the vibrating box, preventing excessive local accumulation that could hinder passage. Furthermore, because the filter screen is tilted downwards, the raw materials move towards the rear of the screen during the vibrating process. After screening, larger particles remain at the rear of the screen. At this point, the tilting motor operates, causing the tilting plate to rotate counter-clockwise, opening the rear of the filter screen. The vibrating box continues to vibrate, allowing the larger particles to fall through the rear of the filter screen.

[0016] 2. The vibrating chamber has an internal collection box. Raw materials passing through the filter fall into the fine material bin inside the collection box. Since the flap is open, larger particles fall into the coarse material bin inside the collection box. After filtration, remove the two bolts at the bottom to pull the collection box out and remove the raw materials from the fine and coarse material bins. In addition, multiple pulleys are installed at the bottom of the vibrating chamber to support it and reduce friction when it moves. Multiple adjustable feet are provided so that the device can be kept level when the placement is uneven. Attached Figure Description

[0028] Reference Figure 1-5 This invention provides a description of an anti-clogging chemical raw material filtration device according to an embodiment of the present invention. The anti-clogging chemical raw material filtration device includes a housing 1. A vibration motor 2 is mounted on the outer wall of the housing 1. A turntable 3 is fixedly connected to the output end of the vibration motor 2. A linkage column 4 is fixedly connected to the outer wall of the turntable 3. A vibration box 5 is disposed inside the housing 1. A linkage groove 6 is formed on the outer wall of the vibration box 5. Multiple limit rods 7 are fixedly connected to the outer wall of the vibration box 5. One end of each limit rod 7 passes through the housing 1 and is fixedly connected to a baffle 8. A spring 9 is fixedly connected to the outer wall of the baffle 8. The other end of the spring 9 is fixedly connected to the outer wall of the housing 1. Sliding grooves 10 are formed on both sides of the inner wall of the vibration box 5. A filter screen 11 is disposed inside the sliding groove 10. A mounting... A mounting plate 13 is fixedly connected to the outer wall of the groove 12 and the filter screen 11. The mounting plate 13 is fixedly connected to the inner wall of the mounting groove 12 by bolts. A flap 14 is movably connected to the inner wall of the vibration box 5. A tilting motor 15 is installed on the outer wall of the vibration box 5. The output end of the tilting motor 15 is fixedly connected to one end of the flap 14. A connecting port 24 is opened on the top of the outer shell 1. A feed inlet 25 is fixedly connected to the top of the outer shell 1. The feed inlet 25 is connected to the outer shell 1 through the connecting port 24. The feed inlet 25 is located above the filter screen 11. In the initial state, the edge of the flap 14 is in contact with the edge of the filter screen 11. At the same time, the bottom of the flap 14 is tightly fitted with the top of the fixing rod 20, so that the top of the filter screen 11 forms a sealed space. When the vibrating motor 2 operates, it drives the turntable 3 and the connected linkage column 4 to rotate synchronously. The linkage column 4 moves along the linkage groove 6 on the outer wall of the vibrating box 5 as the turntable 3 rotates. Because the linkage column 4 performs circular motion, the vibrating box 5 moves back and forth synchronously with the linkage column 4. When the vibrating box 5 moves to the left, the multiple springs 9 on the left are stretched, while the multiple springs 9 on the right are compressed. When the vibrating box 5 moves to the right, the multiple springs 9 on the right are stretched, while the multiple springs 9 on the left are compressed. Since the filter screen 11 is connected to the vibrating box 5 by bolts, the outer shell 1 moves synchronously with the vibrating box 5, thus achieving the function of vibrating screening. The raw material enters from the feed inlet 25 and falls onto the filter screen 11. On the surface, during the reciprocating movement of the vibrating box 5, the raw materials on the filter screen 11 are dispersed. The raw materials that have fallen onto the filter screen 11 will pass through the filter screen 11 due to the reciprocating movement of the vibrating box 5, thereby avoiding the situation where the raw materials accumulate too much in a local area and are difficult to pass through the filter screen 11. In addition, since the filter screen 11 is tilted downward, the raw materials will move to the rear of the filter screen 11 while being vibrated and screened. After screening, the larger raw materials will remain at the rear of the filter screen 11. At this time, the flipping motor 15 runs, driving the flip plate 14 to rotate counterclockwise, opening the rear side of the filter screen 11. At this time, the vibrating box 5 continues to vibrate, and the larger raw materials will fall through the rear of the filter screen 11.

[0029] In another embodiment of this utility model, please refer to Figure 1 The linkage column 4 is located inside the linkage groove 6, and the mounting plate 13 is located inside the mounting groove 12.

[0030] In another embodiment of this utility model, please refer to Figure 2 A collection box 16 is installed inside the bottom of the vibration box 5. The collection box 16 is fixedly connected to the vibration box 5 by bolts. The collection box 16 includes a fine material bin 17 and a coarse material bin 18. The outer wall of the collection box 16 has a groove 19. The fine material bin 17 is located below the filter screen 11, and the coarse material bin 18 is located behind the fine material bin 17. The collection box 16 is installed inside the vibration box 5. The raw material that passes through the filter screen 11 will fall into the fine material bin 17 inside the collection box 16. Since the flap 14 is the main opening body, the raw material with larger particles will fall into the coarse material bin 18 inside the collection box 16. After filtration, the two bolts at the bottom are removed, and the collection box 16 can be pulled out to remove the raw material from the fine material bin 17 and the coarse material bin 18.

[0031] In another embodiment of this utility model, please refer to Figure 2 A fixing rod 20 is fixedly connected to the inner wall of the vibration box 5. The left outer wall of the fixing rod 20 is tightly fitted to the outer wall of the filter screen 11, and the top of the fixing rod 20 is tightly fitted to the bottom of the flip plate 14.

[0032] In another embodiment of this utility model, please refer to Figure 1 and Figure 2 The bottom of the vibration box 5 is equipped with pulleys 21, and there are multiple pulleys 21. The bottom of the outer shell 1 is fixedly connected with support columns 22, and there are multiple support columns 22. The bottom of each support column 22 is threaded with an adjusting foot 23. The multiple pulleys 21 at the bottom of the vibration box 5 support the vibration box 5 and reduce the friction when the vibration box 5 moves. By setting multiple adjusting feet 23, when the placement position is uneven, the multiple adjusting feet 23 can be adjusted to keep the whole device level.
