Description

Technical Field

[0001] This utility model relates to the field of operational technology, and in particular to a multi-stage filtration device for the production of water-based adhesives for tobacco. Background Technology

[0002] Water-based adhesive for cigarettes is formulated by mixing ethylene-vinyl acetate copolymer emulsion with polyvinyl alcohol protective colloid, plasticizer, defoamer, preservative, etc. It is an essential auxiliary material in the cigarette production process. In order to ensure the product quality and performance of water-based adhesive for cigarettes in machine applications, it is necessary to filter it during the production process.

[0003] Comparing the published patent number CN220860815U, which discloses a multi-stage filter for the production of water-based adhesives for tobacco, relating to the field of water-based adhesive production technology; while this utility model includes a filter body, a secondary filter screen fixedly connected to the top of the inner wall of the filter body, a primary filter screen fixedly connected to the bottom of the inner wall of the filter body and located outside the secondary filter screen, a rotating plate rotatably connected to the top of the inner wall of the filter body, and scrapers centrally symmetrically distributed fixedly connected to the bottom end of the rotating plate near the primary filter screen.

[0004] Although the above-mentioned solution involves scraping and cleaning the impurities on the outer surfaces of the secondary and primary filters, with the scraped impurities falling to the bottom of the filter body and being pushed to the first and second discharge troughs by the rotation of the push plate, and then discharged through the discharge pipe to further improve the filtration performance of the filter device, this solution using scraper cleaning not only has the disadvantages of poor cleaning effect, easy residue of water-based adhesive in the mesh of the filter screen, and mesh clogging when the device is stationary, which in turn leads to poor subsequent water-based adhesive filtration effect. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage filtration device for the production of water-based adhesives for tobacco, comprising a filter box, a positioning frame plate threadedly installed on the inner side of the filter box, an outer filter screen cover rotatably installed on the inner side of the positioning frame plate, an inner filter screen cover welded to the inner side of the outer filter screen cover, a material separating base plate fixedly installed on the lower side of the outer and inner filter screen covers, an auxiliary groove provided on the inner side of the outer filter screen cover, an auxiliary slip ring rotatably installed on the inner wall of the auxiliary groove on the outer filter screen cover, a water guide pipe welded to the surface of the auxiliary slip ring, and a drain pipe welded to the surface of the auxiliary slip ring.

[0007] Preferably, a motor body is fixedly mounted on the surface of the positioning frame plate, an auxiliary bracket is fixedly mounted on the output end of the motor body, and the side of the auxiliary bracket away from the motor body is welded to the surface of the outer filter cover.

[0008] Preferably, an embedded support plate is welded and installed on the surface of the outer filter screen, and the surface of the embedded support plate slides against the inner side of the filter box.

[0009] Preferably, the upper end of the water guide pipe is welded and installed inside the positioning frame plate, and a water collection tank is welded and installed on the surface of the positioning frame plate. The water collection tank and the auxiliary slip ring are connected through the water guide pipe.

[0010] Preferably, the filter box is funnel-shaped, and the embedded support plate is V-shaped and fits the filter box.

[0011] Preferably, a support rod is welded to the surface of the filter box, a collection box is welded to the lower end of the support rod, and a feed box pipe is welded to the inner side of the outer filter screen.

[0012] Preferably, the filter box is located outside the outer filter screen cover, the outer filter screen cover is located outside the inner filter screen cover, and the inner filter screen cover is located outside the feed box pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The multi-stage filtration device for producing tobacco water-based adhesives uses a motor to drive the outer filter screen to move, so that the surfaces of the outer and inner filter screens can fully contact the water. At this time, the water can centrifugally clean the tobacco water-based adhesives remaining on the surfaces of the outer and inner filter screens. The cleaned material is discharged at the bottom of the filter box through the contact cleaning of the embedded support plate. This method not only ensures that the tobacco water-based adhesives have a multi-stage filtration effect during filtration, but also ensures that the filtered tobacco water-based adhesives have a self-cleaning effect through the embedded support plate. This reduces the disadvantage of waste caused by the tobacco water-based adhesives adhering to the inner wall of the traditional filter box not being cleaned in time. Furthermore, by setting a water collection tank at the positioning frame plate to wash the inner wall of the filter box, the outer filter screen, and the inner filter screen, the device has the convenience of water washing operation. This improves the disadvantage of the poor cleaning effect of the scraper inside the traditional filter box. Thus, the device has multiple effects of multi-stage filtration, material cleaning, and internal residual material washing.

[0014] (2) The multi-filtration device for producing tobacco water-based adhesives works by driving the motor body to rotate the outer filter screen on the auxiliary support. At this time, the tobacco water-based adhesive poured into the inner filter screen through the feed box pipe at the outer filter screen is centrifugally filtered inside. The tobacco water-based adhesive filtered by the inner filter screen is then filtered at the outer filter screen for secondary filtration. Since the mesh size of the inner filter screen is larger than that of the outer filter screen, the tobacco water-based adhesive can form multiple filtrations through the cooperation of the outer filter screen and the inner filter screen, thereby improving the efficiency of tobacco water-based adhesive filtration.

[0015] (3) The multi-stage filtration device for producing water-based adhesives for tobacco has an inner support plate that abuts against the inner wall of the filter box when the outer filter screen rotates. This allows the filtered water-based adhesives to be effectively removed from the inner wall of the filter box, reducing the waste caused by the adhesion of water-based adhesives to the inner wall of the filter box. The funnel shape of the filter box ensures the concentration of the water-based adhesive material, reducing the splashing range when the water-based adhesives enter the collection box. The V-shaped state of the inner support plate ensures a thorough abutment and cleaning effect on the inside of the funnel-shaped filter box. Attached Figure Description

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-stage filtration device for the production of water-based adhesives for tobacco, including a filter box 1, a support rod 2 welded to the surface of the filter box 1, and a collection box 3 welded to the lower end of the support rod 2. The function of the collection box 3 is to collect the water-based adhesives for tobacco filtered at the filter box 1.

[0023] Furthermore, a positioning bracket plate 4 is threadedly installed on the inner side of the filter box 1. An outer filter screen cover 5 is rotatably installed on the inner side of the positioning bracket plate 4. An inner filter screen cover 6 is welded and installed on the inner side of the outer filter screen cover 5. A material-separating base plate 7 is fixedly installed on the lower side of the outer filter screen cover 5 and the inner filter screen cover 6. By setting the outer filter screen cover 5 and the inner filter screen cover 6 on the inner side of the filter box 1, a dual filtration operation can be formed when filtering water-based adhesives for flue gas. The material-separating base plate 7 on the outer filter screen cover 5 and the inner filter screen cover 6 is a solid plate, which is to form a shielding and sealing at the bottom of the outer filter screen cover 5 and the inner filter screen cover 6. The material-separating base plate 7 can be connected to the outer filter screen cover 5 by thread assembly or fixed by bolts, so that the outer filter screen cover 5 and the material-separating base plate 7 can be separated when the filter box 1 is maintained.

[0024] Furthermore, a feed box pipe 8 is welded and installed on the inner side of the outer filter screen 5. The function of the feed box pipe 8 is to guide the water-based adhesive for flue gas.

[0025] Furthermore, a motor body 9 is fixedly mounted on the surface of the positioning plate 4, and an auxiliary bracket 10 is fixedly mounted on the output end of the motor body 9. The side of the auxiliary bracket 10 away from the motor body 9 is welded and mounted on the surface of the outer filter screen 5. The motor body 9 is existing publicly available technology, and the related power structure is also existing publicly available technology, which will not be described in detail here. When the motor body 9 works, it drives the outer filter screen 5 on the auxiliary bracket 10 to rotate. At this time, the tobacco water-based adhesive poured into the inner filter screen 6 through the feed box pipe 8 at the outer filter screen 5 is centrifugally filtered inside. The tobacco water-based adhesive filtered by the inner filter screen 6 is then subjected to secondary filtration at the outer filter screen 5. Since the mesh size of the inner filter screen 6 is larger than that of the outer filter screen 5, the tobacco water-based adhesive can form multiple filtrations through the cooperation of the outer filter screen 5 and the inner filter screen 6, thereby improving the efficiency of tobacco water-based adhesive filtration.

[0026] Furthermore, an embedded support plate 11 is welded and installed on the surface of the outer filter screen 5. The surface of the embedded support plate 11 slides against the inner side of the filter box 1. The filter box 1 is funnel-shaped, and the shape of the embedded support plate 11 fits the filter box 1 to form a V-shape. By setting the embedded support plate 11 inside the filter box 1, the embedded support plate 11 will abut against and rotate on the inner wall of the filter box 1 when the outer filter screen 5 rotates. This allows the filtered water-based adhesive to have a cleaning effect on the inner wall of the filter box 1, reducing the disadvantage of water-based adhesive adhesion to the inner wall of the filter box 1 and causing waste. The funnel shape of the filter box 1 ensures the concentration of the water-based adhesive, reducing the splashing range when the water-based adhesive enters the collection box 3 inside the filter box 1. The V-shape of the embedded support plate 11 ensures a thorough abutment and cleaning effect on the inside of the funnel-shaped filter box 1.

[0027] Furthermore, an auxiliary groove 12 is provided on the inner side of the outer filter screen 5. An auxiliary slip ring 13 is rotatably installed on the inner wall of the auxiliary groove 12 on the outer filter screen 5. A water guide pipe 14 is welded to the surface of the auxiliary slip ring 13. The upper end of the water guide pipe 14 is welded to the inside of the positioning frame plate 4. A water collection tank 15 is welded to the surface of the positioning frame plate 4. The water collection tank 15 and the auxiliary slip ring 13 are connected through the water guide pipe 14. After water is put into the water collection tank 15, the water will flow through the water collection tank 15 to the inside of the water guide pipe 14, and then to the inside of the auxiliary slip ring 13. Through the positioning of the auxiliary slip ring 13 and the water guide pipe 14, when the motor body 9 drives the outer filter screen 5 to rotate, the auxiliary slip ring 13 and the collection box 3 rotate together, so the auxiliary slip ring 13 will not obstruct the outer filter screen 5.

[0028] Furthermore, a drain pipe 16 is welded and installed on the surface of the auxiliary slip ring 13. The drain pipe 16 is porous. Water that reaches the inside of the auxiliary slip ring 13 through the water guide pipe 14 will be discharged into the drain pipe 16. The two holes of the drain pipe 16 are located at the outer filter screen 5 and the inner filter screen 6, so the water will reach the surface of the outer filter screen 5 and the inner filter screen 6.

[0029] Working Principle: A multi-stage filtration device for the production of water-based adhesives for tobacco products. When filtering the water-based adhesive, the material enters the inner filter screen 6 through the feed pipe 8. Then, the motor body 9 drives the outer filter screen 5 to rotate. The water-based adhesive inside the inner filter screen 6 is centrifugally filtered into the outer filter screen 5, and then centrifugally filtered again through the outer filter screen 5 before being discharged through the inner wall of the filter housing 1. After the water-based adhesive has been filtered, water is added to the water collection tank 15. The water in the water collection tank 15 then flows through… The water pipe 14 and the auxiliary slip ring 13 reach the drain pipe 16 for discharge. At this time, the water at the drain pipe 16 flows to the surface of the outer filter screen 5 and the inner filter screen 6, and the outer filter screen 5 is moved by the motor body 9. The surface of the outer filter screen 5 and the inner filter screen 6 then fully contacts the water. At this time, the water can centrifugally clean the residual tobacco water-based adhesive on the surface of the outer filter screen 5 and the inner filter screen 6. The cleaned material is discharged at the bottom of the filter box 1 through the contact of the embedded support plate 11.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
