Description

Technical Field

[0001] The utility model relates to the technical field of kudzu starch processing, in particular to a kudzu starch slurry impurity removal device. Background Art

[0002] In the industrial production process, kudzu powder can be crushed and pulped after washing and peeling. The kudzu powder can be washed out by flushing the slurry. Since kudzu root is rich in fiber and mechanical washing and peeling mainly cleans the mud and sand, peeling is only a simple treatment and roots will remain on the surface, resulting in some water-insoluble crude fiber, roots and kudzu root skin in the pulping slurry. Therefore, slurry impurity removal and filtration are very important to ensure product purity.

[0003] When filtering impurities in kudzu starch slurry through a rotating cylinder, the kudzu starch slurry diluted with clean water is transported to the rotating cylinder through a spray pipe, and the impurities are filtered through the filter cloth on the surface while the rotating cylinder rotates. However, in the actual process, since the impurities have also been crushed to a certain extent, their size and mass are not large, and after being soaked in clean water and kudzu starch slurry, the impurities are easily attached to the inner wall of the filter cloth, and accumulate more and more, which not only reduces the filtering speed, but also increases the amount of clean water used, which is insufficient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a kudzu starch slurry impurity removal device, which is used to solve the problem that when kudzu starch slurry is filtered through a rotating cylinder and a filter cloth in the prior art, impurities accumulate on the inner wall of the filter cloth, resulting in a reduction in the filtration speed and an increase in the amount of clean water used.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] like Figure 1-6 As shown, the utility model provides a technical solution: a kudzu starch slurry impurity removal device, comprising a hexagonal cage 1 and an axle seat 2, the hexagonal cage 1 is used to replace the rotating cylinder support and installation of the filter cloth 3 in the prior art, the discs at both ends of the hexagonal cage 1 are the same as the discs at both ends of the rotating cylinder, the filter cylinder of the rotating cylinder is removed, and the discs at both ends are connected by six side frames 101, and the surface of the hexagonal cage 1 is sleeved with the filter cloth 3;

[0024] The two ends of the hexagonal cage 1 are fixedly connected with shaft tubes 4, which are installed on the shaft seat 2. A spray pipe 5 is movably inserted in the shaft tube 4. The two shaft tubes 4 are rotatably connected with connecting frames 6. The connecting frames 6 are located inside the hexagonal cage 1, and the opposite surfaces of the two connecting frames 6 are provided with counterweights 7. The counterweights 7 are pulled downward to balance the weights. In addition, the filter cloth 3 has elasticity, so that the connecting frames 6 will not rotate with the hexagonal cage 1.

[0025] A scraper 8 is fixedly installed on one side of the two connecting frames 6, and hooks 9 are hung on the two connecting frames 6. A limiting groove 601 is set at the position corresponding to the hook 9 on the connecting frame 6. A baffle 10 and a tray 11 are fixedly connected between the two groups of hooks 9. The baffle 10 is located above the scraper 8 and the tray 11. The side of the scraper 8 close to the tray 11 is located above the tray 11. The baffle 10 and the tray 11 are hung and installed by the hook 9;

[0026] One of the shaft tubes 4 is connected to the transmission mechanism, and a rotary joint 12 is provided at the end of the other shaft tube 4. The spray pipe 5 passes through the shaft tube 4 and is connected to the feed pipe 13 through the rotary joint 12. The feed pipe 13 is used to transport the kudzu powder slurry diluted with clean water.

[0027] The connecting frame 6 is located in the hexagonal cage 1 near the shaft seat 2, the length and width of the baffle 10 are respectively greater than the length and width of the tray 11, and the length of the tray 11 is greater than the length of the spray pipe 5 between the two shaft tubes 4. In short, the length of the scraper 8 is close to the hexagonal cage 1, so that it can clean most of the inner wall of the filter mesh 3. The baffle 10 is tilted, and the height of the corresponding side of the scraper 8 is greater than the height of the corresponding side of the tray 11. The baffle 10 can prevent the spray pipe 5 from spraying the kudzu powder slurry diluted with clean water onto the scraper 8 and the tray 11, avoiding the secondary attachment of impurities to the inner wall of the filter mesh 3;

[0028] The side of the scraper 8 close to the tray 11 is bent downward, and a cutting edge is provided on the side away from the tray 11. The vertical distance between the cutting edge of the scraper 8 and the shaft tube 4 is greater than the vertical distance between the bottom of the tray 11 and the shaft tube 4. The vertical distance between the scraper 8 and the shaft tube 4 is less than the vertical distance between the side frame 101 of the hexagonal cage 1 and the shaft tube 4, and is greater than the vertical distance between the filter cloth 3 and the shaft tube 4, so as to prevent the side frame 101 from hitting the tray 11 and the scraper 8.

[0029] Working principle: The kudzu powder slurry is diluted with clean water and transported to the spray pipe 5 in the hexagonal cage 1 through the feed pipe 13 and the rotary joint 12. The kudzu powder slurry is sprayed downward through the spray pipe 5 and filtered by the filter cloth 3 on the hexagonal cage 1 to intercept impurities. The hexagonal cage 1 and the filter cloth 3 are connected to the transmission mechanism through the shaft tube 4 and driven to rotate. Under the action of the counterweight block 7, the connecting frame 6 overcomes the resistance of the filter cloth 3 to the scraper 8 by gravity, so that the connecting frame 6 will not rotate together;

[0030] During the rotation of the hexagonal cage 1 and the filter cloth 3, since the filter cloth 3 is supported by the side frame 101 into a hexagonal prism, the scraper 8 can scrape most of the areas of the filter cloth 3 except those corresponding to the side frame 101. The baffle 10 blocks the scraper 8 and the tray 11, and the impurities scraped by the scraper 8 enter the tray 11 and are collected, so that the impurities on most areas of the inner wall of the filter cloth 3 can be removed and cleaned in time, thereby improving the filtering effect and filtering speed while reducing the amount of clean water.

[0031] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
