Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, and specifically to a sewage pump anti-clogging device. Background Technology

[0002] During the cigarette production process, smoke dust is generated during the air separation of tobacco leaves and shreds. The smoke dust is treated in the production line by using a water curtain dust collector to adsorb the smoke dust from the air separation process into the water. Therefore, the water in the water curtain dust collector contains small fibers and impurities. Since the water in the water curtain dust collector is recycled, if the impurities in the water are not treated in time, it will cause the circulation pump supplying water to the water curtain dust collector to become clogged. Therefore, in order to ensure the quality of the water in the water curtain dust collector, filter plates are generally installed in the circulating water tank of the water curtain dust collector to filter out the impurities in the water. The staff can remove the impurities by replacing and cleaning the filter plates regularly.

[0003] Because the filter plates need to be replaced and cleaned regularly, it increases the workload for staff, which is time-consuming and labor-intensive. Utility Model Content

[0041] This application proposes improvements and innovations, and presents the following embodiments.

[0042] In some implementations, please refer to Figures 1 to 6 A sewage pump anti-clogging device is provided for filtering water entering the sewage pump body 1, comprising:

[0043] Box 2, with an opening 21 at the top; a drain hole 22 is provided at the bottom of box 2, and the drain hole 22 is connected to the sewage pump body 1 through a pipe 11.

[0044] Filter mechanism 3 is installed inside housing 2 and has a regeneration structure 31 for restoring filtration function;

[0045] Collection box 4 is externally fixedly connected to box 2; collection box 4 has collection port 41 for collecting filter media scraped out by regeneration structure 31.

[0046] The opening 21 is connected to the raw water pipe 5.

[0047] The water that has adsorbed dust and impurities in the water curtain dust removal equipment enters the housing 2 through the raw water pipe 5. When the raw water passes through the filtration mechanism 3, the impurities are separated from the raw water and the impurities are concentrated in the filtration mechanism 3. The regeneration structure 31 can remove the impurities in the filtration mechanism 3, so that the filtration mechanism 3 can restore its filtration function. The removed impurities are sent to the collection box 4 for storage. The staff only needs to clean the impurities in the collection box 4 periodically. Compared with the situation where the staff need to replace and clean the filter screen 26 regularly, this application can reduce the labor intensity of the staff. At the same time, the continuous operation of the regeneration structure 31 can keep the filtration mechanism 3 in the best filtration state, thereby improving the working efficiency of the filtration mechanism 3.

[0048] In some embodiments, the tank 2 has a first bottom 23 and a second bottom 24, with a drain hole 22 located in the first bottom 23. The height of the first bottom 23 is less than the height of the second bottom 24. A partition 25 is provided at the connection between the first bottom 23 and the second bottom 24. The partition 25 can divide the tank 2 into two areas, which facilitates the separate placement of treated water and ensures the quality of the water entering the sewage pump body 1.

[0049] In some embodiments, the filtration mechanism 3 includes a cylindrical filter box 32, and a plurality of evenly distributed first filter holes 33 are provided on the side of the filter box 32; a regeneration structure 31 is disposed inside the filter box 32 to scrape off the filter media in the first filter holes 33; one end of the filter box 32 is used to connect to the raw water pipe 5, and the other end is fixedly connected to a base plate 34; a through hole 35 is provided on the base plate 34, and a collection box 36 is fixedly connected to the bottom of the base plate 34; a drain port 374 is provided on the collection box 36, and a valve body 37 is provided on the drain port 374; a collection box 4 covers the outside of the collection box 36. After the water passes through the filter box 32, it leaves impurities inside the filter box 32 after passing through the first filter holes 33. The regeneration structure 31 scrapes off the impurities attached to the first filter holes 33, thereby regenerating the filtration function of the filter box 32. The scraped impurities are deposited in the collection box 36 under the action of gravity and water flow. By opening the valve body 37 on the collection box 36, the impurities flow out into the collection box 4. This setup improves filtration efficiency and is simple, practical, and reliable in structure.

[0050] In some embodiments, the valve body 37 includes a door panel 371, a telescopic rod 372, and a spring 373. The door panel 371 is located inside the collection box 36, and the edge of the door panel 371 abuts and seals against the drain outlet 374. The telescopic rod 372 passes through the collection box 4 and is fixedly connected to the door panel 371, and the telescopic rod 372 is slidably connected to the collection box 4. The spring 373 is located outside the collection box 4. One end of the spring 373 is fixedly connected to the telescopic rod 372, and the other end abuts against the outside of the collection box 4. By pushing the telescopic rod 372, the door panel 371 is pushed to separate from the drain outlet 374, thereby realizing the action of discharging impurities. The door panel 371 is normally closed under the action of water pressure and the spring 373. The valve body 37 has a simple structure, reasonable design, and is practical and reliable.

[0051] Specifically, the bottom of the collection box 36 is sloped, and it slopes towards the drain outlet 374. The slope helps impurities to collect towards the drain outlet 374, making it easier to discharge them later.

[0052] In some embodiments, the regeneration structure 31 includes a rod 311, an impeller 312, and a first scraper 313. One end of the rod 311 is fixedly connected to the base plate 34, and the other end is rotatably connected to the impeller 312. The first scraper 313 is fixedly connected to the impeller 312, and the edge of the first scraper 313 is in close contact with the inner wall of the filter box 32. The impeller 312 rotates under hydraulic pressure, which in turn drives the first scraper 313 to rotate as well. The rotating first scraper 313 removes impurities adhering to the first filter holes 33, ensuring the filtration capacity of the first filter holes 33.

[0053] Specifically, the first scraper 313 is spiral-shaped. The spiral shape of the first scraper 313 facilitates pushing the scraped impurities towards the bottom of the filter box 32, allowing the impurities to accumulate at the bottom and be discharged.

[0054] In some embodiments, the lower edge of the partition 25 is fixedly connected to the bottom of the housing 2, and a filter screen 26 is fixedly connected to the upper edge of the partition 25. The filter screen 26 can perform secondary filtration on the water passing through the filter box 32, ensuring that the water quality is clear enough to meet the requirements of the sewage pump body 1 and reducing the possibility of clogging of the sewage pump body 1.

[0055] Specifically, the filter screen 26 has a curved end for intercepting impurities. The curved section facilitates the accumulation of impurities on the filter screen 26, making it easier for workers to remove them.

[0056] In some embodiments, the regeneration structure 31 includes a support frame 314, a conveyor belt 315, and a second scraper 316. The support frame 314 is fixedly connected to the housing 2, and the conveyor belt 315 is mounted on the support frame 314. A first drive motor 317 is provided on the support frame 314, and the first drive motor 317 is drively connected to the conveyor belt 315. The conveyor belt 315 has a plurality of evenly distributed second filter holes. The edge of the conveyor belt 315 is in close contact with the inner wall of the housing 2. One end of the conveyor belt 315 is located inside the housing 2, and the other end is in close contact with the second scraper 316. The second scraper 316 is fixedly connected to the edge of the opening 21, and the collection box 4 is located below the second scraper 316. The second filter holes are opened on the conveyor belt 315. After the raw water passes through the second filter holes, the impurities remain on the conveyor belt 315, and the filtered raw water flows downward to the drain hole 22 and is discharged through the sewage pump body 1. Impurities remaining on the conveyor belt 315 are scraped off by the second scraper 316 as the conveyor belt 315 moves to the collection box 4, thus achieving impurity collection. The regeneration structure 31 makes reasonable use of the function of the conveyor belt 315 and combines it with the function of the filter screen 26, using the conveyor belt 315 to achieve filtration and regeneration functions. The structure is simple, reduces the number of parts, and lowers production costs.

[0057] In some embodiments, the conveyor belt 315 has a filtration section 3151 and a draining section 3152. Along the moving direction of the upper part of the conveyor belt 315, the conveyor belt passes sequentially through the filtration section 3151 and the draining section 3152. The division of the conveyor belt 315 into the filtration section 3151 and the draining section 3152 allows for the separation of impurities from water after filtration, reducing the amount of water carried by impurities into the collection box 4 and minimizing the need for frequent replacement or cleaning of the collection box 4 by personnel.

[0058] Specifically, the filter section 3151 is set horizontally or inclined, and the drain section 3152 is set horizontally or inclined.

[0059] In some embodiments, the filtration mechanism 3 includes a filter cover 38 covering the drain hole 22, and the regeneration structure 31 includes a third scraper 318 that fits and contacts the filter cover 38. The third scraper 318 is connected to a drive rod 319, which is driven by a second drive motor 3110. The second drive motor 3110 is fixedly connected to the housing 2. By driving the third scraper 318 with the motor, impurities on the filter cover 38 are scraped off and pushed into the collection box 4, thereby regenerating the filtration capacity of the filter cover 38 and facilitating the collection of impurities. Its structure is simple, reasonable, practical, and reliable.

[0060] Specifically, the second drive motor 3110 is located above the opening 21.

[0061] In some embodiments, a collection box 36 is fixedly connected to the bottom surface of the first bottom 23, and a drain hole is provided on the first bottom 23, which communicates with the collection box 36. The collection container 4 covers the outside of the collection box 36. The collection box 36 has a simple structure, reasonable design, and is practical and reliable.

[0062] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model.
