Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and specifically to a dustproof device for conveyors. Background Technology

[0002] Conveyors have a long history. The ancient Chinese high-speed waterwheel and water-lifting tippler were the prototypes of modern bucket elevators and scraper conveyors; belt conveyors are currently the main method for conveying bulk materials.

[0003] For example, a dustproof device for a belt conveyor with announcement number CN212798786U and announcement date of March 26, 2021, includes a gate-shaped dustproof cover installed above the conveyor belt. The dustproof device includes an inner sealing sheet and an outer sealing sheet, wherein the inner sealing sheet is made of flexible material and the outer sealing sheet is made of rigid material; the inner sealing sheet is fixedly connected to the inner side of the dustproof cover, and its lower end is bent inward and rests on the conveyor belt.

[0004] When a conveyor transports powdery materials, the powdery materials move quickly on the conveyor belt. During this movement, dust will be generated on the conveyor belt and float into the air.

[0005] In existing technologies, dust filters are usually installed on the outside of conveyor belts to prevent powdery materials from generating dust on the conveyor belt. However, since the dust filters can only provide a simple barrier against dust, the dust accumulates inside the dust filters and cannot be collected. Therefore, there is an urgent need to design a dust control device for conveyors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a dustproof device for conveyors to address the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dustproof device for a conveyor includes a conveyor frame and a dust cover. A suction pipe is installed on the outer wall of the top of the dust cover, and a dust collection box is also installed on the outer wall of the top of the dust cover. An electrostatic column is installed on the inner wall of the dust collection box, and a sealing cover is installed on the outer surface of the top of the dust collection box. One end of the suction pipe is connected to the outer wall of the dust collection box, and a suction shell is installed on the outer wall of the dust collection box away from the suction pipe. A filter screen is installed on the inner wall of the suction shell, and a cleaning rod is rotatably connected to the outer wall of the filter screen via a bearing. A suction motor is fixed to the outer wall of the top of the dust cover by bolts, and a suction fan is installed at the output end of the suction motor. The suction fan is connected to one end of the cleaning rod.

[0009] Furthermore, a fixed socket is provided on the outer wall of one side of the dust cover, and a fixed rod is inserted into the fixed socket. Several curtains are sleeved on the outer wall of the fixed rod.

[0010] Furthermore, the outer wall of the dust cover is provided with a snap-fit ​​block, and the bottom outer wall of the dust cover is rotatably connected to a movable wheel via a bearing.

[0011] Furthermore, the outer wall of the snap-fit ​​block is threaded with several limiting screws, and one end of the limiting screws is connected to the outer wall of the conveyor frame.

[0012] Furthermore, a sliding groove is provided on the outer wall of the top of the conveyor frame, and the moving wheel is slidably connected inside the sliding groove.

[0013] Furthermore, the inner wall of the conveyor frame is provided with a connecting rod, and a cleaning motor is fixed to the outer wall of the connecting rod by bolts. The output end of the cleaning motor is provided with a cleaning roller.

[0014] Furthermore, a conveyor belt is rotatably connected to the inner wall of the conveyor frame via bearings, and the cleaning roller is in contact with the outer wall of the conveyor belt. A fixed frame is provided on the outer wall at the bottom of the conveyor frame, and a collection box is slidably connected to the outer wall at the top of the fixed frame.

[0016] 1. The system consists of a dust cover, suction pipe, dust collection box, electrostatic column, sealing cover, suction housing, filter screen, cleaning rod, suction fan, and suction motor. The suction motor drives the suction fan to rotate, which in turn drives the cleaning rod to rotate. The cleaning rod contacts the filter screen, cleaning it and preventing dust from clogging the filter screen. The suction fan draws the floating dust inside the dust cover into the suction pipe, where it enters the dust collection box. The electrostatic column electrostatically attracts the floating dust inside the dust collection box, and the sealing cover seals the dust collection box, thus absorbing the floating dust inside the dust cover and preventing dust accumulation inside the dust cover.

[0017] 2. Through the dust cover, sliding groove, moving wheels, conveyor frame, snap-fit ​​block and limit screw, the moving wheels drive the dust cover to move in the sliding groove, the snap-fit ​​block snaps into the conveyor frame, and the limit screw is rotated so that the dust cover can be installed on the conveyor frame, realizing the function of portable combination of dust cover and conveyor frame;

[0018] 3. Through the connecting rod, cleaning motor, cleaning roller and collection box, the cleaning motor drives the cleaning roller to rotate on the connecting rod. The cleaning roller contacts the conveyor belt and cleans the dust adhering to the conveyor belt. The cleaned dust falls into the collection box, which improves the cleanliness of the conveyor belt and avoids the problem of floating dust on the conveyor belt being raised again.
