Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter for producing sodium cyanide solution. Background Art

[0002] Sodium cyanide is an inorganic compound that is highly toxic, and its solution is also highly dangerous. When producing sodium cyanide solution, a filter is required to filter out impurities and solid particles in the sodium cyanide solution. Common sodium cyanide solution filters usually use basket filters, which filter out impurities by buffering sedimentation and adding filters.

[0003] For example, CN202220397684.3 discloses a basket filter that can be purged and cleaned with sodium cyanide solution. By setting a spring, a push plate, a limit seat, a limit bolt, and a shock-absorbing pad, when the filter cartridge needs to be cleaned, the eye bolt is pulled, the snap-on cover is removed, and the spring drives the push plate to push the filter cartridge out, thereby achieving the effect of convenient removal.

[0004] In the above patent, when opening the cover on the top of the filter for producing sodium cyanide solution, it is necessary to pull multiple sets of eyebolts before taking out the snap-on cover. The steps are relatively complicated and inconvenient to open the filter. Utility Model Content

[0005] The utility model aims to provide a filter for producing sodium cyanide solution, so as to solve the problem that the existing filter for producing sodium cyanide solution mentioned in the background technology is inconvenient to open the filter.

[0006] To achieve the above object, the utility model provides the following technical solution: a filter for sodium cyanide solution production, comprising: a body and a cover plate, wherein one side of the body is provided with a liquid inlet, a side of the body away from the liquid inlet is provided with a liquid outlet, a filter cartridge is provided inside the body, and a cover plate is provided on the top of the body.

[0007] A rubber pad is fixedly connected to the bottom of the cover plate, a positioning block is fixedly connected to the bottom of the rubber pad, a threaded rod is threadedly connected to the top of the body, a pressure block is welded and fixed to the top of the threaded rod, a connecting block is welded and fixed to the top of the pressure block, a push block is arranged on the outside of the pressure block, a push rod is fixedly connected to one side of the push block, and a fixed block is slidably connected to the outside of the push rod.

[0008] Preferably, a limiting rod is provided on one side of the push rod, and a spring is fixedly connected to one side of the limiting rod.

[0009] Preferably, one end of the spring is fixedly connected to the outer side of the cover plate, and the outer side of the limiting rod is movably connected to the cover plate via a rotating shaft.

[0010] Preferably, the bottom of the fixing block is fixed to the top of the cover plate by welding, and a sliding groove matching the push rod is provided inside the fixing block.

[0011] Preferably, a positioning groove matching the positioning block is provided on the top of the body, and the positioning block is slidably connected to the positioning groove, and the pressing block has a conical shape.

[0012] Preferably, the interior of the cover plate is movably connected with a lever via a rotating shaft, a rotation groove matching the lever is provided inside the cover plate, and a first handle is welded and fixed to the top of the cover plate.

[0013] Preferably, a second handle is welded and fixed to the top of the first handle, a connecting handle is fixedly connected to the top of the filter cartridge, a tension spring is fixedly connected to one side of the lever, and one end of the tension spring is fixedly connected to the rubber pad.

[0014] Compared with the prior art, the filter for producing sodium cyanide solution has the following beneficial effects: the conical pressing block is driven to move upward by rotating the connecting block, and the pressing block will gradually break away from the contact with the pushing block when it moves. At this time, the spring will be reset to push the limit rod to rotate. When the limit rod rotates and breaks away from the limit on the machine body, the movable cover plate is separated from the machine body. By extending the palm into the first handle and then moving the two groups of levers to rotate the two groups of levers, the levers will pull the tension spring to extend. When the two groups of levers rotate, they will enter the connecting handle to clamp the connecting handle. At this time, when the cover plate is opened, the filter cartridge will be driven to separate from the machine body, so that the filter cartridge can be taken out conveniently.

[0015] 1. When producing sodium cyanide solution, it is necessary to filter impurities and particulate matter in the sodium cyanide solution through a filter to ensure the purity of the sodium cyanide solution. When the cover plate on the top of the filter is opened, the threaded rod and the cover plate are driven by rotating the connecting block for threaded transmission. When the threaded rod moves, it can drive the conical pressure block to move upward. When the pressure block moves, it will gradually break away from the contact with the push block. At this time, the spring will reset and push the limit rod to rotate. The limit rod will push the push rod to move, so that the push rod drives the push block to be close to the pressure block. When the push rod moves, it will be limited by the fixed block to prevent the push rod from deflecting. When the limit rod rotates and breaks away from the limit on the body, the movable cover plate is separated from the body. In this way, the filter for the production of sodium cyanide solution can be opened conveniently through the above operation, and the internal maintenance of the filter for the production of sodium cyanide solution is convenient.

[0016] 2. When producing sodium cyanide solution, it is necessary to filter the impurities and particulate matter in the sodium cyanide solution through a filter to ensure the purity of the sodium cyanide solution. When taking out and cleaning the filter cartridge in the machine body, put your palm into the first handle, and then move the two sets of levers to rotate the two sets of levers. The levers will pull the tension springs to extend, and the two sets of levers will enter the connecting handles when they rotate, and clamp the connecting handles. At this time, when the cover is opened, the filter cartridge will be separated from the machine body, which is convenient for taking out the filter cartridge. In this way, the above operations can facilitate the removal and cleaning of the filter cartridge in the filter for sodium cyanide solution production. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The bottom of the cover plate 5 is fixedly connected with a rubber pad 6, the bottom of the rubber pad 6 is fixedly connected with a positioning block 7, the top of the body 1 is threadedly connected with a threaded rod 8, the top of the threaded rod 8 is welded and fixed with a pressure block 9, the top of the pressure block 9 is welded and fixed with a connecting block 10, a push block 11 is arranged on the outside of the pressure block 9, a push rod 12 is fixedly connected to one side of the push block 11, and a fixed block 13 is slidably connected to the outside of the push rod 12; a limit rod 14 is arranged on one side of the push rod 12, and a spring 15 is fixedly connected to one side of the limit rod 14 One end of the spring 15 is fixedly connected to the outer side of the cover plate 5, and the outer side of the limit rod 14 is movably connected to the cover plate 5 through a rotating shaft; the bottom of the fixed block 13 is welded and fixed to the top of the cover plate 5, and a sliding groove matching the push rod 12 is provided inside the fixed block 13; a positioning groove matching the positioning block 7 is provided on the top of the body 1, and the positioning block 7 is slidably connected to the positioning groove, the outer shape of the pressing block 9 is conical, the threaded rod 8 and the cover plate 5 constitute a threaded transmission structure, and the push rod 12 and the fixed block 13 constitute a sliding structure.

[0027] During specific implementation, when producing sodium cyanide solution, it is necessary to filter impurities and particulate matter in the sodium cyanide solution through a filter to ensure the purity of the sodium cyanide solution. When the cover plate 5 on the top of the filter is opened, the threaded rod 8 and the cover plate 5 are threadedly driven by rotating the connecting block 10. When the threaded rod 8 moves, it can drive the conical pressing block 9 to move upward. When the pressing block 9 moves, it will gradually break away from the contact with the push block 11. At this time, the spring 15 will reset and push the limit rod 14 to rotate. The limit rod 14 will push the push rod 12 to move, so that the push rod 12 drives the push block 11 to be close to the pressing block 9. When the push rod 12 moves, it will be limited by the fixed block 13 to prevent the push rod 12 from deflecting. When the limit rod 14 rotates and breaks away from the limit on the machine body 1, the movable cover plate 5 is separated from the machine body 1.

[0028] When the machine body 1 needs to be closed, the positioning block 7 at the bottom of the cover plate 5 is docked with the positioning hole at the top of the machine body 1. After the docking is completed, the connecting block 10 can be reversed to drive the pressing block 9 to move downward. When the pressing block 9 moves, it can squeeze the four groups of push blocks 11 through the conical surface, so that the four groups of push blocks 11 move synchronously. The push block 11 can drive the push rod 12 to push the limit rod 14, and the limit rod 14 can squeeze the spring 15. When the limit rod 14 contacts the machine body 1, the machine body 1 can be squeezed to make the cover plate 5 and the machine body 1 close to each other, and the rubber pad 6 between the cover plate 5 and the machine body 1 will be deformed, so that the connection between the cover plate 5 and the machine body 1 is sealed, and the closing of the machine body 1 is completed. In this way, the filter for producing sodium cyanide solution can be opened conveniently through the above operation, and the internal maintenance of the filter for producing sodium cyanide solution is convenient.

[0029] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The inside of the cover plate 5 is movably connected with a lever 16 through a rotating shaft. A rotating groove matching the lever 16 is opened inside the cover plate 5. A first handle 17 is welded and fixed to the top of the cover plate 5; a second handle 18 is welded and fixed to the top of the first handle 17. A connecting handle 19 is fixedly connected to the top of the filter cartridge 4. A tension spring 20 is fixedly connected to one side of the lever 16. One end of the tension spring 20 is fixedly connected to the rubber pad 6. The lever 16 forms a rotating structure with the cover plate 5 through the rotating shaft.

[0030] In specific implementation, when producing sodium cyanide solution, it is necessary to filter impurities and particulate matter in the sodium cyanide solution through a filter to ensure the purity of the sodium cyanide solution. When taking out and cleaning the filter cartridge 4 in the body 1, the palm of the hand is inserted into the first handle 17, and then the two groups of levers 16 are moved to rotate the two groups of levers 16. The lever 16 will pull the tension spring 20 to extend. When the two groups of levers 16 rotate, they will enter the connecting handle 19 and clamp the connecting handle 19. At this time, when the cover plate 5 is opened, the filter cartridge 4 will be driven to separate from the body 1, which is convenient for taking out the filter cartridge 4. When the filter cartridge 4 needs to be separated from the cover plate 5, the lever 16 can be loosened. At this time, the tension spring 20 will be reset, and the lever 16 will be pulled out of the engagement with the connecting handle 19. Then the palm of the hand is inserted into the second handle 18 to move the cover plate 5 and separate the filter cartridge 4. In this way, the filter cartridge 4 in the filter for producing sodium cyanide solution can be easily taken out and cleaned through the above operation.

[0031] In summary, when using the filter for producing sodium cyanide solution, the sodium cyanide solution is first fed into the body 1 through the liquid inlet 2, and the sodium cyanide solution entering the body 1 is filtered through the filter cartridge 4, impurities are deposited in the filter cartridge 4, and the filtered sodium cyanide solution is discharged through the liquid outlet 3.
