[0001] The utility model relates to the technical field of sandstone processing dust removal equipment, in particular to a dust-proof sandstone sorting device. Background Art
[0002] In the sand and gravel production and processing line, after the raw materials are crushed, they need to go through a screening process to control the particle size of the crushed products. After sorting, the unqualified sand and gravel can be recycled and reprocessed. At present, the screening of sand and gravel mostly relies on vibrating screens. During the operation, due to vibration, a certain amount of dust will be generated, affecting the working environment and endangering the health of the staff. For this reason, fans are often used to extract and discharge the air in the area, which has a poor effect and is prone to secondary dust and environmental pollution. Utility Model Content

DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0028] Specific implementation method 1: Combination Figure 1-7 As shown, a dust-proof sand and gravel sorting device comprises: a chassis 1, an air inlet channel 101 connected to a screening device is provided on the chassis 1, and a working chamber 102 connected to the air inlet channel 101 is provided inside the chassis 1, a rotatable filter cartridge 2 is provided inside the working chamber 102, the bottom of the working chamber 102 is filled with liquid, and the liquid soaks the bottom area of the filter cartridge 2, and an air outlet 103 is provided on one side in front of the working chamber 102; wherein, in order to increase the flow speed of the airflow, a fan is installed in the air inlet channel 101 to ensure negative pressure adsorption;
[0029] There is a closed space above the screening equipment (not shown in the figure). During the sand and gravel screening process, dust generated by vibration gathers in the internal space, and the internal airflow is extracted through the air inlet channel 101, driving the dust from the air inlet channel 101 to the filter cartridge 2 in the working chamber 102. When the airflow passes through the holes on the filter cartridge 2, the dust is filtered. The filtered airflow moves along the working chamber 102 to the air outlet 103 in front and is discharged from the air outlet 103 to complete the dust filtering. At the same time, after running for a period of time, the dust attached to the surface of the filter cartridge 2 may block the holes. The motor installed in front of the working chamber 102 drives the filter cartridge 2 to rotate counterclockwise to change the filtering area of the filter cartridge 2. At the same time, the part of the filter cartridge 2 with soil adhered gradually contacts with the liquid in the bottom area of the working chamber 102 to achieve cleaning operations. No manual maintenance is required, thus extending the working time of the equipment.
[0030] A preferred embodiment, in combination with Figure 4 and Figure 5 As shown, a vertically arranged baffle 3 is provided inside the filter cartridge 2, and both ends of the baffle 3 are connected to the filter cartridge 2 through a rotating shaft, so that the filter cartridge 2 can be divided into left and right parts, thereby preventing the airflow from the air inlet channel 101 from blowing directly to the right area of the filter cartridge 2 and affecting subsequent filtration.
[0031] A preferred embodiment, in combination with Figure 5 As shown, in order to ensure the stability of the baffle 3 itself and keep it in a vertical state, a counterweight block 301 is provided at the bottom of the baffle 3 to utilize gravity to keep its position stable.
[0032] A preferred embodiment, in combination with Figure 4-7 As shown, a scraper 104 and a brush plate 105 in contact with the outer wall of the filter cartridge 2 are respectively provided at the bottom of the working chamber 102. The scraper 104 and the brush plate 105 are fixed to the bottom area of the working chamber 102 by screws. During the rotation of the filter cartridge 2, the scraper 104 scrapes the surface of the filter cartridge 2, and then the brush on the brush plate 105 cleans it again, which can effectively remove the dirt adhered to the surface of the filter cartridge 2 to avoid clogging of the holes.
[0033] A preferred embodiment, in combination with Figure 6 As shown, by installing multiple rubber strips 106 above the scraper 104, the rubber strips 106 are in contact with the surface of the filter cartridge 2, which can reduce the processing and installation accuracy, while improving the scraping effect, and will not scratch the surface of the filter cartridge 2, making it more stable and reliable.
[0034] In a preferred embodiment, the scraper 104 and the brush plate 105 are arranged at 45 degrees to the vertical plane, which is convenient for cleaning mud and avoids the connection position of the water inlet pipe 107 and the water outlet pipe 108 in the working chamber 102, making the structural arrangement more reasonable.
[0035] A preferred embodiment, in combination with Figure 1-3 As shown, a water tank 4 is provided under the chassis 1; a first pipe 401 connected to the inside of the water tank 4 is provided at the air outlet 103, and a fan 402 is provided on the first pipe 401. The liquid in the water tank 4 floods the outlet of the first pipe 401, and the filtered airflow is blown into the liquid in the water tank 4 again through the first pipe 401. The dust is directly in contact with the liquid to achieve filtration again, thereby ensuring the quality of the exhaust airflow.
[0036] In a preferred embodiment, a water inlet pipe 107 and a water outlet pipe 108 are respectively provided on the working chamber 102, and the water outlet pipe 108 is connected to the water tank 4. The water outlet pipe 108 can be discharged into the water tank 4 for collection after the internal liquid becomes turbid, and new liquid can be added through the water inlet pipe 107 to achieve the replacement of the internal liquid and ensure the cleaning effect of the filter cartridge 2.
[0037] A preferred embodiment, in combination with Figure 1-4As shown, in order to reduce liquid consumption, a filter element 5 connected to a water tank 4 is installed on the right side of the chassis 1. The water pump extracts water from the water tank 4 and transports it to the filter element 5 to achieve purification and filtration. The bottom of the filter element 5 is connected to the water inlet pipe 107. In order to ensure water supply, a water pump is required to be added to the water inlet pipe 107. There is also a pipe at the bottom of the filter element 5 that is directly connected to the water tank 4 to achieve the reflux of purified water.
[0038] In the present technical solution, the liquid in the working chamber 102 and the water tank 4 can use water as the liquid medium, which is low in cost, non-toxic and harmless, and is relatively easy to discharge. At the same time, in order to increase controllability, control valves are added to the water inlet pipe 107, the water outlet pipe 108 and other connecting pipelines to achieve the function of controlling the opening and closing of the pipelines, and can be opened as needed.
[0039] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
