Description

Technical Field

[0001] The utility model relates to the technical field of powder dust removal, and more specifically, to a powder production dust removal device. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added when necessary in a certain proportion, which are uniformly mixed, compacted into shape, and cured and hardened. Usually, concrete mixing stations have cement storage (warehouse) tanks, fly ash storage (warehouse) tanks, mineral powder storage (warehouse) tanks, etc., collectively referred to as bulk material (warehouse) tanks or powder (warehouse) tanks (hereinafter referred to as powder tanks). The feeding principle of powder tanks is well known. Bulk powder trucks transport powder to the construction site, and then the conveying pipeline of the bulk material truck is connected to the feed pipeline of the powder tank. The powder in the tank is transported to the powder tank through the gas pressure of the bulk material truck. A large amount of dust is easily generated during the transportation process. Generally, dust is blocked by dust-proof bags to prevent dust from overflowing. After long-term use, the filtering effect deteriorates and the filter needs to be disassembled.

[0003] In response to the above problems, a powder tank dust removal device for a concrete production line with the existing publication number CN218340590U includes a tank body, a blower is fixedly connected to the right side of the top of the tank body, a filter box is fixedly connected to the top of the tank body and located on the left side of the blower, an air inlet pipe is connected to the left side of the blower, the left side of the air inlet pipe is connected to the connection of the filter box, the right side of the blower is connected to the air outlet pipe, the left side of the filter box is connected to a connecting pipe, the other end of the connecting pipe is connected to the connection of the top of the tank body, a filter assembly is provided in the inner cavity of the filter box, springs are fixedly connected to the left and right sides of the top of the filter box, a moving block is fixedly connected to the top of the spring, a limiting rod is fixedly connected to the bottom of the moving block, a limiting groove is provided at the front end of the top of the filter assembly, and the bottom of the limiting rod is plugged into the connection of the limiting groove.

[0004] The dust removal device of the above scheme can extract dust during the transportation process by arranging a blower, a filter box, an air inlet pipe, an air outlet pipe and a connecting pipe, and filter the dust through the first filter screen and the second filter screen to avoid secondary dust pollution. By arranging a moving block to drive the limit rod to move upward, the limit rod is moved away from the limit groove, and the filter assembly is unlocked, which facilitates the disassembly of the first filter screen and the second filter screen to improve the filtering effect of the device. By arranging the above structure, it has the advantage of convenient disassembly of the filter screen, solves the problem of inconvenient disassembly of the filter screen in the existing dust removal device, and can better meet the user's usage needs.

[0005] However, the dust removal device of the above scheme still has problems that need to be improved in the process of dust removal for concrete material distribution. Dust can easily cause the filter to be blocked during the dust filtering process, and the filter needs to be disassembled and cleaned by staff after being blocked. This process is cumbersome and laborious, and will also affect the dust filtering efficiency. Utility Model Content

[0014] By adopting the above technical solution, the staff drives the electric push rod to extend to push the motor and the fixed plate, and at the same time moves the fixed plate in the direction away from the tank body and the filter box, so that the several filter screens on the fixed plate will also be moved out of the filter box with the movement of the fixed plate, and the cleaning brush will also be moved out of the filter box with the action of the electric push rod to prevent the cleaning brush from being separated from the filter screen. At this time, the staff can clean the filter screen or the filter box, thereby improving the service life of the filter box and ensuring the powder dust removal effect.

[0015] The utility model is further configured as follows: a plurality of protrusions are arranged on one end of the fixing plate close to the filter box, and a plurality of grooves corresponding to the protrusions are opened on the filter box.

[0016] By adopting the above technical solution, several fixing plates are fixed on the filter box through the cooperation of protrusions and grooves, so that the cooperation of protrusions and grooves can also play a certain positioning effect, which facilitates the fixing plates to be buckled on the filter box and facilitates the opening and closing of the fixing plates.

[0017] The utility model is further configured as follows: handles are provided at both ends of the collection box.

[0018] By adopting the above technical solution, the staff can take the collection box out of the filter box by using the handle, which is convenient for the staff's operation.

[0019] The utility model is further configured as follows: a fixing block is protrudingly provided on the handle, and a fixing groove for the fixing block to be inserted is provided in the filter box.

[0020] By adopting the above technical solution, the fixing block can be inserted into the fixing groove to achieve fixation, so that the collection box can be fixed in the filter box to recover the powder, preventing the collection box from moving by itself in the filter box and affecting the normal collection effect of the collection box.

[0021] The utility model is further configured as follows: a first magnetic plate is arranged inside the fixing block, and a second magnetic plate which is mutually adsorbed with the first magnetic plate is arranged in the fixing groove.

[0022] By adopting the above technical solution, one end of the fixing block is inserted into the fixing groove, and a part thereof protrudes from the handle, so that when the fixing block is inserted into the fixing groove, the first magnetic plate and the second magnetic plate will be adsorbed together to fix the collection box.

[0023] To sum up, the utility model has the following beneficial effects: the powder blocked on the filter net can be brushed off by the cleaning component, and the brushed off powder or dust can be collected in the collecting box, so as to avoid the powder blocking the filter net and ensure the filtering effect and efficiency of the filter net. After the powder processing is completed, the filter net can be moved out of the filter box, and the powder in the collecting box can be poured out and processed in time. The structure is simple and convenient for the staff to operate, and it will not affect the dust filtering efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the staff can clean the filter screen 5 or the filter box 4, thereby improving the service life of the filter box 4 and ensuring the dust removal effect of the powder. The several fixed plates 6 are fixed to the filter box 4 through the cooperation of the protrusions 7 and the grooves, so that the cooperation of the protrusions and the grooves can also play a certain positioning effect, which is convenient for the fixed plate 6 to be buckled on the filter box 4 and convenient for opening and closing the fixed plate 6.

[0038] The fixing block 14 can be inserted into the fixing groove to achieve fixation, so that the collecting box 12 can be fixed in the filter box 4 to recover the powder, preventing the collecting box 12 from moving by itself in the filter box 4 and affecting the normal collection effect of the collecting box. One end of the fixing block 14 is inserted into the fixing groove, and a part of it protrudes from the handle 13, so that when the fixing block 14 is inserted into the fixing groove, the first magnetic plate and the second magnetic plate 15 will be adsorbed together to achieve the fixation of the collecting box 12.
