[0001] The utility model relates to the technical field of casting, in particular to a dust collecting device for casting. Background Art

[0002] Casting is a manufacturing method that pours liquid material into a mold and forms the desired shape through a cooling or solidification process. The casting dust collector is a specially designed dust collector that can automatically absorb the dust generated during casting, thereby keeping the working environment clean.

[0003] A Chinese patent discloses a dust collecting device for casting (authorization announcement number CN216574776U). This patented technology does not require the towing and retracting smoke conveying pipe, and there is no risk of scratching the smoke conveying pipe during movement, causing smoke to escape, thereby achieving the effect of conveniently conveying smoke.

[0004] With regard to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing dust collecting devices for casting are mostly provided with primary filter plates when in use, so as to reduce the dust removal burden on the bag dust collector, and the filter plates need to be cleaned and replaced regularly during use to prevent blockage. However, when replacing the filter plates in the prior art, the threaded rods or screws used for fixing them mostly need to be unscrewed before replacement. The overall process is relatively cumbersome, affecting work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the prior art has the disadvantage that the filter plate is complicated to replace, so we propose a dust collecting device for casting.

[0006] In order to achieve the above-mentioned objectives, the present application adopts the following technical scheme: a dust collecting device for casting, comprising a dust collecting shell, a conveying pipe is installed at the top of the dust collecting shell, a connecting pipe is installed at the top of the conveying pipe, a replacement groove is provided on the surface of the conveying pipe, a filter plate is slidably connected inside the replacement groove, a fixing plate is fixedly connected to one side of the conveying pipe, a fixing rod is fixedly connected to the bottom end of the fixing plate, a sliding rod is slidably connected inside the fixing rod, a limiting groove is provided on the top of the filter plate, a pressing groove is provided on one side of the sliding rod, an elastic spring is installed inside the pressing groove, a plurality of ejection outlets are provided on one side of the fixing rod, a pressing block is installed on one side of the elastic spring, and the inside of the pressing groove is slidably connected to the pressing block.

[0009] Preferably, a return spring is fixedly connected to the top end of the sliding rod, and the top end of the return spring is fixedly connected to the inside of the fixed rod.

[0010] Preferably, two limiting plates are installed on one side of the conveying pipe. A third sliding groove is formed at one end of the limiting plate close to the filter plate. Third sliding blocks are fixedly connected to both the front end and the rear end of the filter plate, and the third sliding blocks are slidably connected to the inside of the third sliding groove.

[0011] Preferably, sealing plates are installed at both the top end and the bottom end of the filter plate.

[0012] Preferably, the size of the ejection port is adapted to the pressing block.

[0013] The technical effects and advantages of the present utility model:

[0014] In the present utility model, when the staff needs to replace the filter plate, the pressing block is pressed inward to drive the elastic spring to store energy, and at the same time, the sliding rod is released from the limit. Then, the sliding rod is removed from the limit groove, so that the filter plate is released from the limit. Then, the filter plate is pulled out from the replacement groove for replacement.

[0021] Now, in combination with the attached drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Refer to Figure 1 - Figure 3 As shown, the present utility model provides a technical solution: a dust collection device for casting, including a dust collection housing 1. A conveyor pipe 2 is installed at the top of the dust collection housing 1. A connecting pipe 3 is installed at the top of the conveyor pipe 2. A replacement slot 4 is provided on the surface of the conveyor pipe 2. A filter plate 5 is slidably connected inside the replacement slot 4. A fixed plate 6 is fixedly connected to one side of the conveyor pipe 2. A fixed rod 7 is fixedly connected to the bottom end of the fixed plate 6. A sliding rod 8 is slidably connected inside the fixed rod 7. A limit slot 9 is provided at the top end of the filter plate 5. A pressing slot 10 is provided on one side of the sliding rod 8. An elastic spring 11 is installed inside the pressing slot 10. A plurality of elastic outlets 12 are provided on one side of the fixed rod 7. A pressing block 13 is installed on one side of the elastic spring 11. The inside of the pressing slot 10 is slidably connected to the pressing block 13. When the staff needs to replace the filter plate 5, press the pressing block 13 inward to drive the elastic spring 11 to store energy, and at the same time release the limit of the sliding rod 8. Then, move the sliding rod 8 out of the limit slot 9 to release the limit of the filter plate 5. Then, pull the filter plate 5 out of the replacement slot 4 for replacement. After the replacement is completed, slide the sliding rod 8 into the limit slot 9 again. At this time, the pressing block 13 quickly pops into the elastic outlet 12 due to the elastic force of the elastic spring 11, so as to limit the sliding rod 8, thereby achieving rapid disassembly and replacement when the sliding rod 8 is blocked, and improving the work efficiency of the staff.

[0023] Refer to Figure 3 As shown in this implementation: First chutes 14 are provided at both the front end and the rear end inside the pressing slot 10. First sliders 15 are fixedly connected to both the front end and the rear end of the pressing block 13. The inside of the first chute 14 is slidably connected to the first slider 15. Through the setting of the first chute 14 and the first slider 15, it can effectively prevent the pressing block 13 from falling off when the elastic spring 11 drives it to pop out, and improve the stability during use.

[0024] Refer to Figure 4As shown in the figure, in this embodiment: second sliding grooves 16 are provided at both the front end and the rear end inside the fixed rod 7. Second sliding blocks 17 are fixedly connected to both the front end and the rear end of the sliding rod 8. The second sliding grooves 16 are slidably connected to the second sliding blocks 17. Through the arrangement of the second sliding grooves 16 and the second sliding blocks 17, a stable guiding effect can be formed when the sliding rod 8 moves inside the fixed rod 7, preventing the sliding rod 8 from shifting during movement and causing the sliding rod 8 to fail to slide into the limiting groove 9, thereby affecting the fixation of the filter plate 5.

[0025] Referring to Figure 5 As shown in the figure, in this embodiment: a return spring 18 is fixedly connected to the top end of the sliding rod 8. The top end of the return spring 18 is fixedly connected to the inside of the fixed rod 7. Through the arrangement of the return spring 18, when the filter plate 5 needs to be replaced, the sliding rod 8 is released from the limit. At this time, the return spring 18 drives the sliding rod 8 to quickly bounce back from the limiting groove 9, so that the filter plate 5 is quickly released from the limit, further improving the replacement efficiency.

[0026] Referring to Figure 2 As shown in the figure, in this embodiment: two limiting plates 19 are installed on one side of the conveying pipe 2. A third sliding groove 20 is provided at one end of the limiting plate 19 close to the filter plate 5. Third sliding blocks 21 are fixedly connected to both the front end and the rear end of the filter plate 5. The third sliding groove 20 is slidably connected to the third sliding blocks 21. Through the arrangement of the third sliding groove 20 and the third sliding blocks 21, stable limitation can be formed when the filter plate 5 is replaced, thereby improving the replacement stability of the filter plate 5.

[0027] Referring to Figure 2 As shown in the figure, in this embodiment: sealing plates 22 are installed at both the top end and the bottom end of the filter plate 5. Through the arrangement of the sealing plates 22, the conveying pipe 2 will not leak due to the gap between the replacement groove 4 and the filter plate 5 when inhaling gas, improving the sealing performance during use.

[0028] Referring to Figure 3 As shown in the figure, in this embodiment: the size of the ejection port 12 is adapted to the pressing block 13. Through the adapted arrangement, the fixing effect after the replacement of the filter plate 5 can be significantly improved, and it is not easy to generate shaking and falling off.

[0029] Working principle: When the staff needs to replace the filter plate 5, press the pressing block 13 inward to drive the elastic spring 11 to store energy. At the same time, release the limit of the sliding rod 8, then move the sliding rod 8 out of the limit groove 9 to release the limit of the filter plate 5, and then pull the filter plate 5 out of the replacement groove 4 for replacement. After the replacement is completed, slide the sliding rod 8 into the limit groove 9 again. At this time, the pressing block 13 quickly pops into the ejection port 12 due to the elastic force of the elastic spring 11 to limit the sliding rod 8, so as to achieve rapid disassembly and replacement when the sliding rod 8 is blocked, improving the work efficiency of the staff. Through the setting of the first chute 14 and the first slider 15, it can effectively prevent the pressing block 13 from falling off when the elastic spring 11 drives it to pop out, improving the stability during use. Through the setting of the second chute 16 and the second slider 17, a stable guiding effect can be formed when the sliding rod 8 moves inside the fixed rod 7, preventing the sliding rod 8 from shifting during movement and causing the sliding rod 8 to be unable to slide into the limit groove 9, thus affecting the fixation of the filter plate 5. Through the setting of the return spring 18, when the filter plate 5 needs to be replaced, release the limit of the sliding rod 8. At this time, the return spring 18 drives the sliding rod 8 to quickly bounce back from the limit groove 9, so that the filter plate 5 is quickly released from the limit, further improving the replacement efficiency. Through the setting of the third chute 20 and the third slider 21, stable limit can be formed when the filter plate 5 is replaced, thus improving the replacement stability of the filter plate 5. Through the setting of the sealing plate 22, when the conveying pipe 2 inhales gas, leakage will not occur due to the gap between the replacement groove 4 and the filter plate 5, improving the sealing performance during use. Through the matching setting, the fixing effect after the replacement of the filter plate 5 can be significantly improved, and it is not easy to shake and fall off.
