Description

Technical Field

[0001] The present application relates to the technical field of concrete production, and in particular to an environmentally friendly dust filtering device for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as cementitious material, sand, stone as aggregates and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. Concrete will produce a lot of dust during the processing and production process, which will also cause the processing and production environment of concrete to deteriorate and affect the health of workers.

[0003] The method of using a scraper to brush away the dust attached to the filter screen is usually inconvenient to brush away the dust in the mesh of the dust screen. The mesh of the filter screen is easily blocked during long-term use, which reduces the dust filtering effect. A Chinese patent (Announcement No.: CN219964384 U) discloses an environmentally friendly dust filtering device for concrete production. The air compressor conveys compressed gas to the backblowing pipe and discharges it from the air hole, reversely sweeps the filter cylinder, blows away the dust in the mesh of the filter cylinder, and avoids clogging of the mesh of the filter cylinder. However, since the dust-containing gas in the above document enters the filter cylinder through the connecting pipe, and the backblowing pipe blows the side of the filter cylinder, it is easy for the dust in the gas to fall into the dust collecting box, and then it is blown into the air outlet pipe by the backblowing pipe, so that the dust-containing gas only filters out the large particles of dust and part of the dust contained in it, while the fine dust is blown into the air outlet pipe by the backblowing pipe, so that the air discharged by the air outlet pipe still has a certain dust content, thereby reducing the dust filtering effect.

[0015] By adopting the above technical solution, the concave block can be driven to move back and forth in the connecting bin, so that the concave block can drive the knocking plate to move back and forth through the knocking rod.

[0016] Furthermore, the motor is fixed to the bottom of the inner cavity of the connecting bin, and the transverse plate is fixed to the inner wall of the concave block.

[0017] By adopting the above technical solution, the driving plate can stably rotate in the inner cavity of the connecting bin, and the horizontal plate can drive the concave block to move.

[0018] Furthermore, a reserved groove is provided at the top end of the transverse plate, and the push rod is slidably connected to the inner side of the reserved groove.

[0019] By adopting the technical solution, the push rod can move forward and backward inside the cross plate.

[0020] Furthermore, the connection assembly includes a vertical pole, a support plate, and an anti-slip ring fixedly mounted on the outer surface of the vertical pole.

[0032] Among them, through holes are opened at both ends of the filter cartridge 1, and the knocking rod 72 is slidably connected to the inner side of the through hole, so that the knocking rod 72 can penetrate into the interior of the filter cartridge 1, so as to push the knocking plate 71 to move in the inner cavity of the filter cartridge 1.

[0033] Moreover, a connecting hole is opened on the opposite wall of the two connecting chambers 76, and the knocking rod 72 is slidably connected to the inner side of the connecting hole, so that the two connecting chambers 76 are connected to the filter cartridge 1, so that the knocking rod 72 can be moved out of the connecting chamber 76 and moved to the inner cavity of the filter cartridge 1, and the two connecting chambers 76 are respectively fixed on the left and right walls of the filter cartridge 1.

[0034] In addition, the front and rear walls of the inner cavity of the connecting bin 76 are provided with sliding grooves, and the support block 75 is slidably connected to the inner side of the sliding groove.

[0038] It should be noted that the electronic components appearing in the text are all commonly known to the public in the prior art, and the electrical components appearing in the text are all connected to the controller and the power supply. The control method of this implementation is controlled by the controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also well known in the art. Therefore, the control method and circuit connection are no longer explained in detail in this utility model.

[0039] The working principle of the above embodiment is:

[0040] When in use, the dust generated during the production and processing of concrete is discharged into the cyclone along with the air by the fan, so that the cyclone filters out large particles of dust and part of the dust in the air, and enters the filter cartridge 1 through the connecting pipe 2. When the gas enters the filter cartridge 1, it can drive the impeller 3 to rotate. When the impeller 3 rotates, it drives the narrow plate 5 to move through the vertical rod 41, so that the narrow plate 5 can drive the filter cartridge 6 to rotate in the filter cartridge 1. At the same time, the control end controls the two motors 79 to work, so that the two motors 79 drive the driving plate 78 to rotate in the inner cavity of the connecting bin 76. When the driving plate 78 rotates, it can drive the push rod 77 to perform a circular motion, so that the push rod 77 moves in a circular motion. While moving in a circle, it can move forward and backward inside the cross plate 74, so that the push rod 77 can drive the cross plate 74 to move left and right, so that the cross plate 74 can drive the concave block 73 to move left and right in the inner cavity of the connecting bin 76, so that the concave block 73 can drive the knocking rod 72 to move out of the connecting bin 76 and move to the inside of the filter cartridge 1, that is, the knocking rod 72 can drive the knocking plate 71 to move left and right in the inner cavity of the filter cartridge 1, so that the two knocking plates 71 can knock on the filter screen cartridge 6, and the knocking plate 71 can knock the dust on the filter screen cartridge 6, which can reduce the dust discharged into the external environment through the air outlet pipe due to the blowing force of the wind direction, and can reduce the dust content in the discharged air, thereby improving the dust filtering effect.
