Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement processing, and in particular to a screening and filtration device for the production of cement-based self-leveling materials. Background Technology
[0002] Cement-based self-leveling material is a dry-mixed mortar made of cement as the main binder, supplemented with graded aggregates, redispersible latex powder, water-reducing agents, retarders and other additives. After being mixed with water, it forms a highly fluid slurry that automatically levels itself by gravity to form a flat and dense floor layer. It has the characteristics of high construction efficiency, fast hardening, high strength and low shrinkage, and is widely used in building floor leveling, subbase or surface treatment.
[0003] When self-leveling cement is first produced, it will clump together, so it needs to be screened to remove impurities and separated into different specifications. However, existing self-leveling cement screening and filtration devices all use straight plate screens, and large particles of self-leveling cement can easily completely clog the screen holes, affecting the screening.

[0005] Therefore, the purpose of this utility model is to provide a screening and filtration device for the production of cement-based self-leveling materials. The purpose is to automatically clean and prevent clogging of the screen holes of the cement-based self-leveling material screening device, and to collect dust during the screening process.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a screening and filtration device for the production of cement-based self-leveling materials, including a screening frame, a rotating screening mechanism rotatably installed in the inner cavity of the screening frame, and a dust collection mechanism fixedly installed on the outer surface of the screening frame; The rotary screening mechanism includes a screening component, which includes a motor.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a screening and filtration device for the production of cement-based self-leveling materials. The screening and filtration device for the production of cement-based self-leveling materials includes a screening frame 1, a rotating screening mechanism 2 is rotatably installed in the inner cavity of the screening frame 1, and a dust collection mechanism 3 is fixedly installed on the outer surface of the screening frame 1. The rotary screening mechanism 2 includes a screening component 21, which includes a motor 211. The outer surface of the motor 211 is fixedly connected to the outer surface of the screening frame 1 through a fixing frame. The output end of the motor 211 is fixedly mounted with a rotating shaft 212 through a reducer. The outer surface of the rotating shaft 212 is fixedly mounted with a main gear 213.
[0019] The screening assembly 21 also includes a screening cylinder 214, the outer surface of which is rotatably connected to the inner surface of the screening frame 1, and a toothed block 215 is fixedly installed on the outer surface of the screening cylinder 214, the outer surface of which meshes with the outer surface of the main gear 213.
[0020] The screening assembly 21 also includes a sealing plate 216, the outer surface of which is rotatably connected to the inner surface of the screening cylinder 214, and a feed pipe 217 is connected to the right side of the sealing plate 216.
[0021] The rotary screening mechanism 2 also includes a connecting frame 22. The top of the connecting frame 22 is fixedly connected to the inner wall of the screening frame 1. An extension rod 23 is fixedly installed on the right side of the connecting frame 22. The right end of the extension rod 23 is fixedly connected to the left side of the sealing plate 216. A cleaning bristle 24 is fixedly installed on the outer surface of the extension rod 23.
[0022] During use, the motor 211 drives the rotating shaft 212 to rotate, and the rotating shaft 212 drives the toothed block 215 to rotate through the main gear 213. The toothed block 215 drives the screening cylinder 214 to rotate, moving the cement material. During the movement, different particle sizes in the material will fall into the holes of different sizes. When the screening cylinder 214 rotates, the cleaning bristles 24 stuck on the extension rod 23 will insert into the holes in the screening cylinder 214, and at the same time, they will clean the material stuck in the holes. The three extension rods 23 and the cleaning bristles 24 will increase the cleaning effect.
[0023] Example 2 Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the dust collection mechanism 3 includes a suction pump 31. The back of the suction pump 31 is fixedly connected to the front of the screening frame 1. The top of the suction pump 31 is connected to an air inlet pipe network 32. The opposite ends of the air inlet pipe network 32 are connected to the outer surface of the screening frame 1.

[0026] During use, when the cement material is being screened, the flying cement dust will be sucked into the air intake pipe network 32 of the suction pump 31, and then injected into the collection bag 36 through the air intake frame 35, so that the cement dust is collected in the collection bag 36, while the gas is discharged from the hole of the exhaust box 34.
[0027] The remaining structure is the same as that in Example 1.
[0028] Based on embodiments 1-2, the working principle of this utility model is as follows: Cement material is poured into the screening cylinder 214 through the feed pipe 217, and then the rotating shaft 212 is driven to rotate by the motor 211. The rotating shaft 212 drives the toothed block 215 to rotate through the main gear 213. The toothed block 215 drives the screening cylinder 214 to rotate, moving the cement material. During the movement, particles of different sizes in the material will fall into holes of different sizes. When the screening cylinder 214 rotates, the cleaning bristles 24 stuck on the extension rod 23 will be inserted into the holes in the screening cylinder 214, and at the same time, the material stuck in the holes will be cleaned off. The three extension rods 23 and the cleaning bristles 24 will increase the cleaning effect. During the screening of cement material, the flying cement dust will be sucked into the air intake pipe network 32 of the suction pump 31, and then injected into the collection bag 36 through the air intake frame 35, so that the cement dust is collected in the collection bag 36. At the same time, the gas is discharged from the hole of the exhaust box 34.
