Description

Technical Field

[0001] This utility model relates to the field of silica sand particle screening technology, specifically a multi-stage silica sand particle screening device. Background Technology

[0002] Silica sand, also known as silicon dioxide or quartz sand, is a hard, wear-resistant, and chemically stable silicate mineral. It is a primary raw material in glass production, used to manufacture flat glass, glass bottles and jars, and glass fibers. The purity and particle size of silica sand have a significant impact on the quality and performance of the glass.

[0003] The production and processing of silica sand typically includes processes such as mining, crushing, screening, washing, magnetic separation, and flotation to remove impurities and obtain silica sand products of different particle sizes and purities.

[0004] As disclosed in Chinese Patent CN204656958U, a silica sand screening device consists of a frame and screening components mounted on the frame. The screening components are divided into a drum screen and a water-washing screen. The drum screen has mesh openings for screening large particles, while the water-washing screen has mesh openings for screening medium particles. The water-washing screen is positioned below the drum screen, and a water-washing device covering the entire water-washing screen is arranged above it. Silica sand is separated into large particles by the drum screen and medium and small particles by the water-washing screen according to the required specifications. Large particles can be further crushed, medium particles can be sent to the mill, while small particles can be kept out of the mill, thus reducing over-grinding, improving work efficiency, and reducing material loss. Using a water-washing screen to screen medium and small particles reduces dust from small particles, especially ultrafine powder, while ensuring a high proportion of small and medium particles are separated.

[0005] However, in the existing technology, when screening silica sand particles, the silica sand particles are usually in a wet state. In a wet state, the silica sand particles will often stick together and agglomerate, which will easily cause the screen to be blocked, thus affecting the screening effect.

[0006] Therefore, we urgently need to provide a multi-stage silica sand particle screening device. Utility Model Content

[0026] 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.

[0027] Example 1:

[0028] In existing technologies, when screening silica sand particles, the particles are usually in a moist state. Moist silica sand particles often stick together and agglomerate, easily causing screen clogging and affecting the screening efficiency. Please refer to [the relevant documentation / reference needed]. Figures 1-3 The embodiment provides a multi-stage silica sand particle screening device, which can effectively improve the dryness of silica sand particles and prevent silica sand particles from sticking and clogging during the screening process. The multi-stage silica sand particle screening device includes a base 1, a screening device installed on the top of the base 1, a cleaning device installed inside and at the bottom of the screening device, and a drying device installed on the top of the screening device.

[0029] The drying device includes a drying structure and an auxiliary structure. The auxiliary structure is installed at the top and bottom of the drying structure. The drying structure includes a drying drum 101. A heating box 105 is installed in the middle of the outer surface of the drying drum 101. A heating tube 106 is installed inside the heating box 105. A stirring motor 107 is installed in the middle of the top surface of the drying drum 101. A stirring rod 108 is connected to the output end of the stirring motor 107. A scraper 109 is installed at the bottom end of the stirring rod 108. The auxiliary device includes a feed pipe 102. A connecting pipe 103 is provided on the bottom right side of the feed pipe 102. A fan 104 is installed in the middle section of the connecting pipe 103.

[0030] The feed pipe 102 is installed in the middle of the top surface of the drying barrel 101 near the left side of the installation hole. The connecting pipe 103 is installed in the middle of the bottom surface of the drying barrel 101 near the right end of the round hole. The bottom surface of the scraper 109 is slidably connected to the bottom surface inside the drying barrel 101.

[0031] By using the drying device, the heating tube 106 heats the sand while the stirring motor 107 drives the stirring rod 108 and scraper 109 to stir the silica sand particles, thereby effectively drying the silica sand particles and improving the screening efficiency.

[0032] Before screening the silica sand, the silica sand particles are placed into the drying drum 101 through the feed pipe 102. Then, the heating pipe 106 is activated to heat the silica sand particles inside the drying drum 101, and the stirring motor 107 is activated to drive the stirring rod 108 and scraper 109 to rotate, thereby heating and drying the silica sand particles. This keeps the silica sand particles dry and prevents them from sticking together and clogging the screening plate 205, which would affect the screening effect. Afterwards, the airlock fan 104 is activated to discharge the screened material through the connecting pipe 103.

[0033] Example 2:

[0034] Based on Implementation 1, the existing technology still has a problem where some silica sand particles get stuck inside the sieve holes during the sieving process, affecting the sieving effect. Please refer to [the relevant documentation]. Figures 4-5This embodiment provides a multi-stage silica sand particle screening device that can effectively clean the screening holes and ensure screening effect. The device includes a screening box 201, a screening motor 202 installed in the middle right side of the screening box 201, a convex shaft 203 connected to the output end of the motor 202, a lever 204 connected to the outer surface of the convex shaft 203, a screening plate 205 installed at the left end of the lever 204, a material hopper 206 installed in the middle left side of the screening box 201, and a discharge pipe 207 installed in the middle of the bottom surface of the screening box 201 near the right end. The bottom of the screening box 201 is connected to the top of the base 1, and the top of the screening box 201 is fixedly connected to the bottom of the drying barrel 101. A circular hole is formed in the middle of the top surface of the screening box 201 near the right end, and its inner wall is connected to the bottom end of the outer surface of the connecting pipe 103.

[0035] The cleaning device includes an asynchronous motor 301, with a transmission component 302 connected to the output end of the asynchronous motor 301. A rotating shaft 303 is connected inside the transmission component 302. A brush plate 304 is mounted on the outer surface of the rotating shaft 303 near its top, and a rotating rod 305 is mounted on the outer surface of the rotating shaft 303 near its bottom. The asynchronous motor 301 is detachably installed in the middle of the bottom surface of the screening box 201. The outer surface of the rotating shaft 303 near its bottom is connected to the middle of the bottom surface of the screening box 201 via a sealed bearing. The bottom surface of the rotating rod 305 is slidably connected to the inner bottom surface of the screening box 201, and the bottom of the brush plate 304 is slidably connected to the top surface of the screening plate 205.

[0036] By setting up a screening device and a cleaning device, multi-stage screening of silica sand particles can be achieved. During the multi-stage screening process, the brush plate 304 is used to brush and clean the screening plate 205, thereby effectively preventing the screening plate 205 from becoming blocked and affecting the screening effect.

[0037] After the silica sand particles enter the screening box 201, the screening motor 202 is started, driving the cam shaft 203 to rotate. This cam shaft 203 then vibrates the paddles 204 and screening plates 205, achieving the screening effect for the silica sand particles. Multiple screening plates 205 are used to complete multi-stage screening of the silica sand particles. Since the aperture of the multiple screening plates 205 decreases from top to bottom, silica sand particles of different diameters can be screened and discharged through the distribution hopper 206. Finally, the discharged material... Pipe 207 discharges the screened silica sand particles and simultaneously starts the asynchronous motor 301 to drive the transmission component 302. The output end of the asynchronous motor 301 drives the worm to rotate. The outer surface of the worm meshes with the worm wheel, thereby causing the worm wheel to drive the rotating shaft 303 to rotate. When the rotating shaft 303 rotates, it drives the brush plate 304 to rotate, thereby using the brush plate 304 to brush and clean the screening plate 205, effectively preventing the screening plate 205 from getting stuck and clogging, which would affect the screening effect.
