[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the silica powder processing collection device provided by this utility model;

[0027] Figure 5 This is a schematic diagram of the material screening section in this utility model.

[0028] The silica powder processing collection device includes: a processing tank 1, a top cover 2 on the top of the processing tank 1, a feed pipe 3 on the top cover 2, a first control valve 4 on the feed pipe 3, an isolation plate 5 fixedly connected inside the processing tank 1, the feed pipe 3 passing through the isolation plate 5, a driving part 6 in the middle of the top cover 2, a scraping part 7 and a screening part 8 fixedly connected to the driving part 6, a discharge area 9 at the lower end of the interior of the processing tank 1, a first collection part 10 at the lower end of the exterior of the processing tank 1, and a second collection part 11 on the side of the processing tank 1.

[0029] Open the first control valve 4 on the feed pipe 3 to send the material into the processing tank 1. Then start the drive unit 6 to drive the scraper unit 7 and the sieve unit 8 to operate synchronously, scraping off the powder adhering to the inner wall of the processing tank 1. The lower sieve unit 8 cooperates with the discharge area 9 to generate vibration, screening the material falling on the sieve unit 8. Powder that meets the particle size requirements falls into the discharge area 9, while that that does not meet the requirements enters the first collection unit 10. At the same time, start the second collection unit 11 to extract and collect the light powder or dust at the upper end of the internal space of the processing tank 1. Finally, after the collection process is completed, transfer the material in a unified manner.

[0030] The drive unit 6 includes a mounting base 61, on which a drive motor 62 is mounted. The output end of the drive motor 62 is connected to a transmission shaft 63, which passes through the top cover 2 and the partition plate 5.

[0031] The drive shaft 63 passes through the top cover 2 and the partition plate 5, transmitting the power of the drive motor 62 to the scraping section 7 and the screening section 8, enabling the scraping section 7 and the screening section 8 to perform scraping and screening operations synchronously, thereby improving processing and collection efficiency.

[0032] The scraping part 7 includes a first fixing sleeve 71, which is fixedly connected to the drive shaft 63. Two sets of the first fixing sleeve 71 are provided and fixedly connected to the drive shaft 63. A fixing rod 72 is fixedly connected to the first fixing sleeve 71. An arc-shaped scraper 73 is fixedly connected to the end of the fixing rod 72. The arc-shaped scraper 73 is close to the inner wall of the processing tank 1. A retaining edge 74 is provided on the inner side of the arc-shaped scraper 73.

[0033] The arc-shaped scraper 73 is close to the inner wall of the processing tank 1. During the rotation, it scrapes off the silica powder adhering to the inner wall of the processing tank 1, preventing the powder from adhering to the tank wall for a long time and agglomerating, which would affect subsequent processing. The retaining edge 74 plays a certain role in blocking the scraped powder, preventing the powder from sliding off the inside of the arc-shaped scraper 73 or flying in the internal space of the processing tank 1.

[0034] The screening section 8 includes a second fixed sleeve 81, which is fixedly connected to the transmission shaft 63. A limit plate 82 is provided at the lower end of the second fixed sleeve 81. A spring 83 is sleeved on the second fixed sleeve 81. An inclined screen 84 is slidably connected to the second fixed sleeve 81. The lower end of the inclined screen 84 is provided with evenly distributed edge grooves 85.

[0035] The limiting plate 82 limits the inclined screen 84. The spring 83 is sleeved on the second fixed sleeve 81 and its lower end contacts the inclined screen 84. When the drive shaft 63 drives the screening part 8 to rotate, the interaction between the edge groove 85 and the arc protrusion 92 of the discharge area 9 causes the inclined screen 84 to vibrate, which improves the speed and quality of screening and ensures that powder materials of different particle sizes can be effectively separated.

[0036] The discharge area 9 includes a conical discharge slope 91. The upper edge of the conical discharge slope 91 is provided with evenly distributed arc-shaped protrusions 92. The height of the arc-shaped protrusions 92 corresponds to the edge grooves 85. The bottom of the conical discharge slope 91 is provided with a discharge pipe 93, and a second control valve 94 is provided on the discharge pipe 93.

[0037] The arc-shaped protrusions 92 are evenly arranged on the upper edge of the conical discharge slope 91, and their height corresponds to the edge groove 85 of the inclined screen 84. During the rotation of the inclined screen 84, the arc-shaped protrusions 92 play a certain pushing role on the inclined screen 84, strengthen the vibration of the inclined screen 84, and improve the screening effect.

[0038] The first collection part 10 includes a discharge port 101 and a placement groove 102. The discharge port 101 is located at the lower end of the processing tank 1, and a first collection box 103 is slidably connected to the placement groove 102.

[0039] The first collection box 103 is slidably connected to the placement trough 102, which makes it convenient for staff to quickly pull it out of the placement trough 102 for material transfer, thus improving the efficiency of the collection work. At the same time, it can also ensure the sealing of the collection process and prevent powder material from leaking out during the screening process.

[0040] The second collection unit 11 includes a base 111, on which a pump 112 and a second collection box 115 are provided. The output end of the pump 112 is connected to a discharge pipe 113, and a third control valve 114 is provided on the discharge pipe 113. The two ends of the discharge pipe 113 are respectively connected to the upper end of the processing tank 1 and the second collection box 115.

[0041] The extraction pump 112 serves as a power unit, capable of extracting light silica powder or dust that may be present near the upper part of the internal space of the processing tank 1, and conveying it to the second collection box 115 through the discharge pipe 113, thereby collecting this part of the powder, reducing material waste, and reducing dust pollution to the working environment.

[0042] The working principle of the silica powder collection device for processing provided by this utility model is as follows:

[0043] Open the first control valve 4 on the feed pipe 3 to send the material into the processing tank 1. Then start the drive unit 6 to drive the scraper unit 7 and the sieve unit 8 to operate synchronously, scraping off the powder adhering to the inner wall of the processing tank 1. The lower sieve unit 8 cooperates with the discharge area 9 to generate vibration, screening the material falling on the sieve unit 8. Powder that meets the particle size requirements falls into the discharge area 9, while that that does not meet the requirements enters the first collection unit 10. At the same time, start the second collection unit 11 to extract and collect the light powder or dust at the upper end of the internal space of the processing tank 1. Finally, after the collection process is completed, transfer the material in a unified manner.

[0044] Compared with related technologies, the silica powder collection device for processing provided by this utility model has the following advantages:

[0045] The drive unit 6 drives the scraper unit 7 and the screening unit 8 to work synchronously, which, together with the discharge area 9, improves the efficiency of material screening. When the arc-shaped scraper 73 scrapes the powder on the inner wall of the processing tank 1, the baffle 74 prevents the powder from sliding and flying off the inner side of the arc-shaped scraper 73. Combined with the extraction pump 112 to collect the light powder material floating in the upper part of the internal space of the processing tank 1 during the screening process, the material collection capacity is increased, the material waste is effectively reduced, and the overall sealing of the structure prevents the powder from leaking out during the screening process and causing safety hazards.
