Description

Technical Field

[0001] This utility model relates to the technical field of belt sealing devices, and more specifically, to a belt sealing device with an internal dust removal function. Background Technology

[0002] A belt conveyor is a mechanical device for continuously transporting materials. It consists of a drive unit, conveyor belt, idlers, drums and frame, etc. It uses the principle of friction transmission to realize the horizontal or inclined transport of bulk materials or packaged goods.

[0003] A search revealed CN217497636U, which discloses a dust suppression and sealing device for a belt conveyor. The device includes a lower sealing assembly and a dust suppression hood. The dust suppression hood has an inverted U-shaped cross-section and is positioned above the belt conveyor. The lower sealing assembly is located on both sides of the lower part of the dust suppression hood and is used to seal the area below the belt conveyor. By completely sealing the belt conveyor, both the space above and below the belt are sealed, preventing dust generated during belt operation from spreading outside the sealing hood and reducing air pollution. Sealing the upper and lower channels of the belt effectively controls dust movement within a confined space.

[0004] The aforementioned technical solution effectively reduces dust diffusion during material conveying by sealing the upper and lower channels of the belt conveyor. However, in practical applications, this belt conveyor dust suppression sealing device still has certain limitations. For example, although a vacuum cleaner can remove suspended dust inside the dust suppression hood and reduce the internal dust concentration, it is difficult to completely clean stubborn dust that adheres to or cakes on the surface of the conveyor belt using only adsorption. After long-term operation, these caked materials may affect the normal operation of the conveyor belt and even interfere with the stable transport of materials, thereby reducing the working efficiency of the equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a belt sealing device with internal dust removal function, so as to solve the problem that in the prior art, some belt conveyor dust suppression sealing devices reduce dust by closing the channel, but the vacuum cleaner cannot effectively remove the dust that has accumulated on the surface of the conveyor belt, which may affect the operating efficiency and material conveying stability in the long term.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a belt sealing device with internal dust removal function, comprising...

[0007] The belt conveyor body has a frame on its outer side along its length. Side fixing plates are fixedly installed on the top two surfaces of the frame. Several upper sealing covers are bolted to the top of the side fixing plates, and lower sealing plates are fixedly installed at the bottom.

[0008] A soft-bristled cleaning brush has its upper surfaces at both ends in contact with the lower surface of the middle part of the frame. The two ends of the soft-bristled cleaning brush are bolted to the frame. The middle part of the soft-bristled cleaning brush has bristles, and the upper surface of the bristles is in contact with the lower surface of the belt device body. Several cleaning rollers are provided on the side of the soft-bristled cleaning brush along its length, and the outer surfaces of the several cleaning rollers are movably installed on the surface of the belt device body.

[0009] The upper surface of the top of the upper sealing cover is fixedly installed with a vacuum cleaner. The bottom end of the vacuum cleaner is fixedly installed with a first suction port. The top end of the first suction port is fixedly sleeved with the inner wall of the top of the motor. A connecting pipe is fixedly sleeved on the side of the vacuum cleaner. The bottom end of the connecting pipe is fixedly sleeved with a second suction port. The outer surface of the end of the second suction port is fixedly sleeved with the inner wall of the side of the lower sealing cover.

[0010] The frame has an L-shaped plate fixedly installed on the lower surface of the middle section, and U-shaped limit frames are bolted to the upper surfaces of both sides of the bottom of the frame. The two U-shaped limit frames are arranged in parallel. A motor is fixedly installed on the side of the L-shaped plate. A short connecting rod is fixedly sleeved on the output end of the motor. A long connecting rod is hinged to the end of the short connecting rod away from the motor. A movable block is hinged to the end of the long connecting rod away from the short connecting rod. There are two movable blocks, and the side edges of the two movable blocks are slidably installed with the middle of the two U-shaped limit frames.

[0011] Among them, a multi-faceted support is rotatably installed on one side of the two movable blocks that are close to each other, and a second motor is fixedly installed on the surface of the movable block away from the long connecting rod. The output end of the second motor is fixedly sleeved with the middle part of the multi-faceted support. The surface of the multi-faceted support is rotatably installed with the outer surfaces of the middle and both ends of the plurality of cleaning rollers. The plurality of cleaning rollers are arranged in a ring array about the axis of the multi-faceted support.

[0012] The lower sealing plate has an opening in the middle of the side away from the second dust inlet, and an inspection door is provided at the opening. The inspection door is bolted to the outer surface of the lower sealing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, by setting up structures such as soft-bristled cleaning brushes, the main body of the belt conveyor is sealed during material transport operations by structures such as upper sealing covers and lower sealing panels surrounding the main body and frame of the belt conveyor, reducing dust generation. A vacuum cleaner and its bottom suction port are used to remove dust. Simultaneously, as the belt conveyor operates, the belt surface at the bottom comes into contact with the soft-bristled cleaning brushes. As the belt moves, the brushes clean it, loosening and removing any clumps of material. Furthermore, a cleaning roller, adjusted to fit snugly against the bottom of the belt, cleans any dust missed by the brushes. During this process, the cleaned dust is removed by a vacuum cleaner connected to a connecting pipe and suction port, achieving dust reduction. This structure facilitates the loosening, cleaning, and removal of materials and dust clumps on the belt surface, improving the stability of the belt conveyor's operation.

[0015] In the above scheme, by setting up structures such as cleaning rollers, during the actual cleaning process, the movable block connected by the first motor and other structures slides down to the lower middle part along the middle of the U-shaped limit frame. Then, the second motor is controlled to rotate at a certain angle, driving the multi-faceted support connected to the output end to rotate along the inner wall of the two movable blocks, rotating the unused cleaning roller to the top position. After that, the first motor is used to adjust the cleaning roller to fit against the lower surface of the belt of the main belt of the belt device, and cleaning continues. Thus, by using the first motor and other structures to adjust the lifting of the multi-faceted support, and the second motor to adjust the rotation of the multi-faceted support and the cleaning roller set on the surface, the cleaning roller can be quickly switched, avoiding the impact on efficiency and dust overflow caused by stopping to replace the cleaning roller.

[0028] The frame 2 has an L-shaped plate 7 fixedly installed on the lower surface of the middle section. U-shaped limit frames 11 are bolted to the upper surfaces of both sides of the bottom of the frame 2. The two U-shaped limit frames 11 are arranged in parallel. A motor 8 is fixedly installed on the side of the L-shaped plate 7. A short connecting rod 9 is fixedly connected to the output end of the motor 8. A long connecting rod 10 is hinged to the end of the short connecting rod 9 away from the motor 8. A movable block 12 is hinged to the end of the long connecting rod 10 away from the short connecting rod 9. There are two movable blocks 12, and the side edges of the two movable blocks 12 are slidably installed with the middle of the two U-shaped limit frames 11. By setting up the motor 8, after the motor 8 is started, the short connecting rod 9 connected to its output end will rotate. The short connecting rod 9 drives the hinged long connecting rod 10 to move. During the movement of the long connecting rod 10, it will pull the hinged movable block 12 to move along the middle of the U-shaped limit frame 11, thereby adjusting the lifting and lowering of the multi-faceted support column 13 and other structures.

[0029] Among them, a multi-faceted support column 13 is rotatably installed on one side of the two movable blocks 12 that are close to each other, and a motor 2 15 is fixedly installed on the surface of the movable block 12 away from the long connecting rod 10.

[0031] The working process of this utility model is as follows:

[0032] During the material transport operation of the belt conveyor body 1, the belt conveyor body 1 is sealed by the upper sealing cover box 4 and the lower sealing plate 5 covering the outer perimeter of the belt conveyor body 1 and the frame 2 to reduce dust. The dust is removed by the vacuum cleaner 16 and the suction port 17 at the bottom. At the same time, when the belt conveyor body 1 is in operation, the belt surface at the bottom will come into contact with the soft bristle cleaning brush 6. As the belt moves, the soft bristle cleaning brush 6 will clean the belt, cleaning and loosening the material that has hardened on it. In addition, the cleaning roller 14, which is adjusted to fit the bottom of the belt of the belt conveyor body 1, can clean some of the dust missed by the soft bristle cleaning brush 6. During the above process, the cleaned dust will be sucked away by the vacuum cleaner 16 connected to the connecting pipe 18 and the second suction port 19, thus achieving dust reduction.

[0033] In the actual cleaning process, since the cleaning roller 14 is mainly used to clean the dust left by the soft bristle cleaning brush 6 or some of the dust that is electrostatically adsorbed on the surface of the belt, the surface of the cleaning roller 14 will be contaminated by dust after a period of time. At this time, the staff can perform a switching operation without stopping the machine to replace it. The specific operation is as follows: first, use the motor 18 and other structural adjustment to slide the movable block 12 down along the middle of the U-shaped limit frame 11 to the lower middle part. Then, control the motor 2 15 to rotate a certain angle, drive the multi-faceted support 13 connected to the output end to rotate along the inner wall of the two movable blocks 12, rotate the unused cleaning roller 14 to the top position, and then use the motor 18 to adjust the cleaning roller 14 to fit against the lower surface of the belt of the belt device body 1 and continue cleaning.
