[0002] With the development of the construction industry, the requirements for building materials are getting higher and higher, especially the requirements for waterproof performance. Waterproof materials are widely used in various construction projects because they can effectively prevent water penetration. In the production process of waterproof materials, the quality of the pulp is directly related to the performance of the final product. The pulp often contains incompletely dissolved particles, fibrous substances and other impurities. These impurities not only affect the appearance of the product, but more importantly, they will reduce the waterproof performance of the product and even cause the product to fail. Although the existing pulp filtering device can remove some larger particles of impurities, it is not effective in removing fine particles and colloidal substances. In addition, when the filtering device is in continuous operation, a large amount of coarse pulp accumulates on the top, and these coarse pulps will clog the mesh, affecting production efficiency.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0027] like Figures 1-6As shown, a slurry filtering device for waterproof material production includes: a square cylinder 1, three groups of support bars 11 are fixedly connected to the inner walls on opposite sides of the square cylinder 1, two square frames 12 and a bottom frame 13 are provided inside the square cylinder 1, filter frames 14 are fixedly connected to the bottoms of the two square frames 12, and a screen 15 is provided inside the bottom frame 13; a stirring component, the stirring component is arranged inside the square cylinder 1, and is used to stir the slurry of waterproof material, and a disassembly and assembly component is arranged on the installation head 21, and is used to install and fix the installation head 21 and the sleeve 22.

[0028] The top of the square tube 1 is fixedly connected to a feeding tube 5 , the bottom of the square tube 1 is fixedly connected to an inclined platform 51 , and the outside of the square tube 1 near the inclined platform 51 is fixedly connected to a discharge pipe 52 .

[0029] When screening the raw pulp of the waterproof material, the raw pulp is poured into the feeding barrel 5, the raw pulp enters the interior of the square cylinder 1, and the raw pulp falls into the topmost square frame 12, and is preliminarily filtered through the filter frame 14. The filtered raw pulp falls into the middle square frame 12, and then passes through the filter frame 14 with a smaller mesh for secondary filtration. The raw pulp after the secondary filtration falls on the screen 15 of the bottom frame 13, and then passes through the screen 15 for three times to obtain fine raw pulp. During the refiltration, the raw pulp in each stage of filtration is turned over by the stirring component, which helps to improve the filtration efficiency. After the filtration is completed, the coarse raw pulp needs to be cleared out, and the filter frame 14 and the screen 15 are taken out for cleaning. First, the sealing door on the square cylinder 1 is opened, and then the top mounting head 21 is removed by the disassembly and assembly component, and then the square frame 12, the bottom frame 13 and the sleeve 22 are removed in turn for easy cleaning. Example

[0030] On the basis of Example 1, the stirring assembly includes: a rotating rod 2, a mounting head 21, a sleeve 22, a scraper 23 and a drive motor 24. The rotating rod 2 is inside the square cylinder 1, and the rotating rod 2 passes through the filter frame 14 and the screen 15 respectively. A mounting head 21 is provided at the top of the rotating rod 2, and two sleeves 22 are provided on the outside of the rotating rod 2. The mounting head 21 and the outside of the two sleeves 22 are respectively fixedly connected to two symmetrically arranged scrapers 23. A drive motor 24 is fixedly installed at the bottom of the square cylinder 1, and the drive shaft at the top of the drive motor 24 extends to the inside of the square cylinder 1. The mounting head 21 is located on the top filter frame 14, and the two sleeves 22 are respectively located on the middle filter frame 14 and the screen 15.

[0031] When stirring the raw pulp, the driving motor 24 is started to drive the rotating rod 2 to rotate. When the rotating rod 2 rotates, it drives the mounting head 21 and the sleeve 22 to rotate, and the rotation drives the scraper 23. The rotating scraper 23 turns the raw pulp, thereby pushing away the rough raw pulp at the bottom to avoid clogging in the network card and affecting the filtration, thereby improving the filtration efficiency. Example

[0032] On the basis of Example 1, the disassembly and assembly components include: an insertion hole 3, an insertion block 31, a movable groove 32, a fixed block 33 and a fixed groove 34. The bottom of the installation head 21 is provided with an insertion hole 3, the top of the rotating rod 2 is fixedly connected to the insertion block 31, the insertion hole 3 is provided with movable grooves 32 on opposite sides, the movable grooves 32 are internally provided with fixed blocks 33, the insertion block 31 is provided with fixed grooves 34 on opposite sides, the installation head 21 is provided with two L-shaped grooves 35 that are conductive with the two movable grooves 32, and the L-shaped grooves 35 are internally provided with L-shaped Rod 36, a spring 37 is connected between the opposite sides of the two L-shaped rods 36 and one side of the inner wall of the two L-shaped grooves 35, and one end of the two plug-in blocks 31 is connected to the two L-shaped rods 36 respectively. A guide groove 38 is provided at the top of the mounting head 21 and is connected to the two L-shaped rods 36. A button 39 is provided inside the guide groove 38. The bottom end of the button 39 is fixedly connected to the connecting rod 310, and the bottom end of the connecting rod 310 is fixedly connected to the pressure block 311. The pressure block 311 is arranged in a trapezoidal structure, and the top of the two L-shaped rods 36 is relatively inclined at one end.

[0033] When it is necessary to clear out the coarse raw pulp and clean the filter frame 14 and the screen 15, the sealing door on the square cylinder 1 is opened, and then the button 39 on the top of the installation head 21 is pressed. The button 39 pushes the pressing block 311 downward through the connecting rod 310, and the pressing block 311 is squeezed between the two L-shaped rods 36 to separate the two L-shaped rods 36. When the L-shaped rods 36 move to both sides, the spring 37 is squeezed to contract and store energy. The L-shaped rod 36 drives the fixing block 33 to withdraw from the inside of the fixing groove 34, and then the installation head 21 is lifted up to remove the installation head 21. Remove the top frame 12, then remove the sleeve 22 from the rotating rod 2, and then take out the frame 12 and the bottom frame 13. After cleaning, arrange the frame 12 and the bottom frame 13 according to the mesh size and install them on the rotating rod 2, and install the two sleeves 22. Then install the mounting head 21, align the insertion hole 3 at the bottom of the mounting head 21 with the insertion block 31, and then release the button 39. The spring 37 releases its elasticity and pushes the two L-shaped rods 36 together. The L-shaped rod 36 pushes the fixing block 33 into the fixing groove 34 to fix the mounting head 21.

[0035] When removing the sleeve 22, first unscrew the screw 44 from the positioning hole 45 to release the fixation of the sleeve 22. When fixing it again, screw the screw 44 into the positioning hole 45 to fix it. Remove the bolt 43 to disconnect the rotating rod 2 from the drive shaft of the drive motor 24. When reconnecting, splice the splicing groove 4 at the bottom end of the rotating rod 2 with the splicing block 41 at the top end of the drive shaft of the drive motor 24, and then use the bolt 43 to pass through the through hole 42 to fix it.
