Description

Technical Field

[0001] This utility model relates to the field of putty powder sieving technology, specifically a putty powder sieving device. Background Technology

[0002] Putty is a base material used for wall repair and leveling, laying a good foundation for subsequent decoration (painting, wallpapering). There are two types of putty: interior wall putty and exterior wall putty. Exterior wall putty needs to withstand wind and sun exposure, so it has higher adhesive content and strength, but a slightly lower environmental protection index. Interior wall putty has a better overall index, is healthier and more environmentally friendly, so it is not used for interior walls or exterior walls. Putty is usually made of gypsum or cement, which makes the surface rougher and easier to adhere firmly.

[0003] Putty powder needs to be screened before use. Although existing screening devices use enclosed boxes for screening, dust can easily spread at the inlet and outlet of the screening box, thus directly causing dust pollution of the surrounding air. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A putty powder sieving device includes a sieving box 1, a collecting mechanism 7 installed on the bottom outer wall of the sieving box 1, a feeding hopper 4 fixedly connected to the top outer wall of the sieving box 1 and communicating with the sieving box 1, an arc-shaped fixing frame 5 installed on the outer wall of the sieving box 1, and multiple dust suction hoods 6 installed on the outer wall of the fixing frame 5, a discharge port opened on one side outer wall of the sieving box 1, and a discharge pipe 2 fixedly connected to the inner wall of the discharge port, and a blower 3 installed on the outer wall of the sieving box 1, and the blower 3 is located around the discharge pipe 2.

[0024] In use, the collection mechanism 7 facilitates the collection of dust overflowing from the screening box 1 during operation. The feed hopper 4 and the discharge pipe 2 are open structures where dust is prone to overflow. The cooperation between the dust suction hood 6 and the air box 3 facilitates the transportation of dust to the collection mechanism 7.

[0025] For details, please refer to Figure 3-4 The inner walls of both sides of the collection box 8 are rotatably connected to the same filter tube 13, and the outer wall of the filter tube 13 is provided with multiple arc-shaped openings. The inner wall of the arc-shaped openings is fixedly connected to a dust removal filter cloth 14. The arc-shaped openings on the filter tube 13 facilitate the installation of the dust removal filter cloth 14. The dust removal filter cloth 14 is designed to keep dust in the collection box 8. A fan 9 is fixedly connected to one side of the outer wall of the collection box 8, and the inlet of the fan 9 is rotatably connected to an air duct. One end of the air duct is connected to the filter tube 13. The connection between the fan 9 and the filter tube 13 facilitates the extraction of air from the collection box 8 when the fan 9 is started, in conjunction with the filter tube 13, thereby facilitating the suction of dust into the collection box 8.

[0026] For details, please refer to Figure 2-4 A motor 12 is fixedly connected to one outer wall of the collection box 8, and the output shaft of the motor 12 is fixedly connected to the filter tube 13. The motor 12 can directly drive the filter tube 13 to rotate. Cleaning components 10 are installed on the inner walls of both sides of the collection box 8.

[0027] For details, please refer to Figure 4-5 The cleaning assembly 10 includes a cleaning box 15 fixedly connected to the inner walls of both sides of the collection box 8, and a sliding seat 17 slidably connected to the inner wall of the cleaning box 15. The cleaning box 15 facilitates the installation of the sliding seat 17. A cleaning brush 18 is fixedly connected to one outer wall of the sliding seat 17, and multiple springs 16 are fixedly connected to the inner wall of the cleaning box 15 on the outer wall of the cleaning brush 18 and the filter tube 13. One end of the spring 16 is fixedly connected to the sliding seat 17. The spring 16 drives the sliding seat 17 to extend. When the sliding seat 17 extends, it causes the cleaning brush 18 and the dust removal filter cloth 14 on the filter tube 13 to come into close contact.

[0028] Working principle: When the screening box 1 is working, putty powder is fed into the screening box 1 through the feed hopper 4. The screened putty powder is discharged directly through the discharge pipe 2. During the screening process, dust overflows through the feed hopper 4 and the discharge pipe 2. At this time, the fan 9 on the collection box 8 starts. When the fan 9 starts, it directly sucks the dust into the collection box 8 through the dust suction hood 6 and the air box 3. Then, the dust is directly filtered out by the dust removal filter cloth 14 on the filter pipe 13. When the fan 9 stops, the dust falls into the collection box 11 under the influence of gravity, which facilitates the centralized treatment of the dust. When cleaning the dust removal filter cloth 14 on the filter pipe 13, the motor 12 starts and drives the filter pipe 13 to rotate. When the dust removal filter cloth 14 comes into contact with the cleaning brush 18, the dust adhering to the dust removal filter cloth 14 is easily cleaned off. The cleaning brush 18 is driven by the spring 16 to make close contact with the dust removal filter cloth 14, thereby improving the cleaning efficiency.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
