Description

Technical Field

[0001] The present invention belongs to the field of cleaning devices, and specifically relates to a cleaning device for a belt conveyor. Background Technology

[0002] A belt conveyor is a conveying device that uses a belt to transport materials. When transporting materials with a high water content, the materials often stick to the belt. If the materials stuck to the belt are not removed in time, the materials will continue to accumulate, which will not only easily cause friction between the belt and the roller, affecting the service life of the belt and the roller, but also easily cause the belt to deviate, causing the materials to fall, reducing the belt transportation efficiency, and worsening the on-site environment.

[0003] At present, belt cleaning mainly adopts manual shoveling, which has the disadvantages of high labor intensity and low cleaning efficiency; and some belts are located high above the ground, making manual shoveling difficult. In addition, for safety reasons, the machine must be shut down when shoveling, which greatly affects production operations. SUMMARY OF THE INVENTION

[0004] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a belt conveyor cleaning device, which can automatically clean the materials adhering to the belt without stopping the belt conveyor, which not only reduces the difficulty of cleaning, but also improves the cleaning efficiency.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a material cleaning device for a belt conveyor, comprising a traveling trolley, a silo and a vacuum pump group, wherein the vacuum pump group and the silo are both mounted on the traveling trolley; an air suction port is provided on the top of the silo, a material suction port is provided on the side wall of the silo, and a material discharge port is provided at the bottom of the silo; the air suction port is connected to the vacuum pump group through a vacuum tube, a material suction pipe is installed at the material suction port, and the material discharge port is connected to the material discharge pipe through a discharge valve; a vertical guide frame is installed on the traveling trolley; a support seat is slidably installed on the vertical guide frame; the silo is installed on the support seat, and the support seat is driven by a lifting drive unit to move up and down along the vertical guide frame; the present invention utilizes a vacuum pump group to continuously extract the air in the silo to form a negative pressure inside the silo, thereby utilizing the negative pressure effect to suck the material adhered to the belt into the silo; at the same time, since the height of the silo is adjustable, it is convenient to meet the belt cleaning requirements at different height positions, effectively reducing the difficulty of cleaning and improving the cleaning efficiency.

[0006] The preferred solution of the above technical solution is: a filter is provided on the vacuum tube to prevent the material from being sucked into the vacuum pump group and affecting the normal use of the vacuum pump group.

[0007] The preferred solution of the above technical solution is: the lifting drive unit is an automatic telescopic device installed on the walking trolley.

[0008] The preferred solution of the above technical solution is as follows: The lifting drive unit includes a rotary motor, a transmission gear, and a vertical rack; the rotary motor is installed on the support base and is located between the silo and the vertical guide rail frame; the vertical guide rail frame includes two vertically spaced guide rails, and the vertical rack is installed on any one of the vertical guide rails; the transmission gear is installed on the motor shaft of the rotary motor and meshes with the vertical rack.

[0009] The preferred solution of the above technical solution is as follows: A pulse jet blower facing the discharge port is provided at the upper part of the silo to prevent blockage of the discharge port.

[0010] The preferred solution of the above technical solution is as follows: A wire reel for coiling the power cord is provided on the trolley to prevent the power cord from being accidentally pulled off during the movement of the trolley and improve the overall neatness and aesthetics.

[0011] As described above, a cleaning device for a belt conveyor of the present invention has the following beneficial effects:

[0012] The present invention uses the negative pressure effect to suck the materials adhered to the belt into the silo and discharges them to the designated position through the discharge pipe, realizing automatic cleaning of the belt. This cleaning method not only eliminates the need for the belt conveyor to stop operation, but also reduces the labor input and improves the cleaning efficiency; at the same time, since the height of the silo is adjustable, it is convenient to meet the cleaning requirements of belts at different height positions, thereby effectively reducing the cleaning difficulty.

For the convenience of narration, the definitions of each direction in the following embodiments are as follows: the height direction of the vertical guide frame 4 is defined as the up and down direction, the arrangement direction of the vertical guide frame 4 is defined as the front and back direction, and the horizontal direction perpendicular to the arrangement direction of the vertical guide frame 4 is defined as the left and right direction. Based on this, Figure 3 In the view shown, the upper side and the lower side of the paper surface are the up direction and the down direction respectively; the front side and the back side of the paper surface are the front direction and the back direction respectively, and the left side and the right side of the paper surface are the left direction and the right direction respectively.

[0021] Embodiment 1:

[0022] As Figures 1 to 3As shown in the figure, the belt cleaning device involved in this embodiment includes a traveling trolley 1, a silo 2, a vacuum pump group 3, and a lifting drive unit. Among them, the vacuum pump group 3 includes a vacuum pump and a drive motor for driving the operation of the vacuum pump. The vacuum pump group 3 is installed on the traveling trolley 1. The air extraction port at the top of the silo 2 is connected to the vacuum pump through a vacuum tube, and a suction pipe for sucking materials is provided at the material suction port on the side wall of the silo 2. A discharge valve 23 is provided at the discharge port at the bottom of the silo 2, and a discharge pipe 24 is provided at the outlet of the discharge valve 23. The discharge valve 23 can not only convey the materials discharged from the discharge port into the discharge pipe 24, but also play a sealing role to prevent air from being sucked in from the discharge port and affecting the negative pressure material suction of the silo 2. The vertical guide rail frame 4 is located on one side of the vacuum pump base 3, and the vertical guide rail frame 4 includes two vertically spaced guide rails 41 and a top connecting rod 42 for connecting the tops of the two vertically guide rails 41. The silo 2 is slidably installed on the vertical guide rails 41 through a support seat 5, and the support seat 5 is located above the vacuum pump group 3. The lifting drive unit includes a rotary motor 61, a transmission gear 61, and a vertical rack 63. The rotary motor 61 is installed on the support seat 5 and is located between the silo 2 and the vertical guide rail frame 4. The vertical rack 63 is installed on any one of the vertical guide rails 41. The transmission gear 61 is installed on the motor shaft of the rotary motor 61 and meshes with the vertical rack 63, so that the transmission gear 61 rolls on the vertical rack 63, thereby driving the rotary motor 61 and the support seat 5 connected to the rotary motor 62 to move up and down, and further realizing the adjustment of the height position of the silo 2 to meet the belt cleaning at different height positions. In this embodiment, each pipeline is preferably made of a hose that can be bent arbitrarily, such as a PVC hose or a metal hose.

[0023] When it is necessary to clean the materials adhered to the belt on the belt conveyor, the cleaning device of this application needs to be moved to a preset working position beside the belt conveyor; then, adjust the height position of the silo 2 according to the height of the belt to be cleaned (here the belt is the return belt) until the suction pipe 22 can conveniently clean the materials on the belt; then, align the discharge pipe 24 with the preset discharge position and start the vacuum pump group 3 to form a negative pressure inside the silo 2, and use the negative pressure effect to suck the materials on the belt into the silo 2 and discharge them to the preset discharge position through the discharge pipe 24; since this device is mainly used for cleaning the accumulated materials on the return belt, it does not affect the normal material transportation of the belt and ensures the normal progress of production operation.

[0024] Since in this embodiment, the support seat 5 is placed directly above the vacuum pump group 3 and the gear-rack matching method is used to adjust the height of the support seat 5; the structural compactness of the entire device is greatly improved, thereby effectively reducing the floor area of the entire device, making the device compact, and thus facilitating the belt cleaning in a smaller construction space.

[0025] Preferably, a filter needs to be provided on the vacuum tube 21 to prevent materials from being sucked into the vacuum pump set 3 and interfering with the normal use of the vacuum pump set 3.

[0026] To improve the aesthetics of the entire device, as Figure 1 and Figure 2 shown, the vacuum pump set 3 can be first placed in the installation box 7 and then installed on the walking trolley 1. Since the device needs to be powered by connecting to a power source through a power cord during operation, and the power cord has a certain length, its unfolded and stacked state not only looks messy but is also extremely likely to be accidentally pulled and broken. Therefore, a wire reel 8 for storing and winding the power cord can be installed on the walking trolley 1; in this embodiment, the wire reel 8 is preferably connected to the installation box 7 to further ensure the overall compactness of the device.

[0027] Furthermore, a pulse jet blower facing the discharge port is provided at the upper part of the storage bin 2, which can blow compressed air towards the discharge port to prevent the discharge port from being blocked; the pulse jet blower is a prior art, and it mainly includes an electromagnetic pulse valve, a pulse controller, a compressed air storage cylinder, and a blowback pipe; the electromagnetic pulse valve is used to connect the compressed air storage cylinder and the blowback pipe, and the pulse controller is used to pulse-control the electromagnetic pulse valve to achieve intermittent blowing of the blowback pipe.

[0028] Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 lies only in the specific structure and layout of the lifting drive unit.

[0030] In this embodiment, the lifting drive unit is an automatic telescopic device installed on the walking trolley 1, and the movable end of the automatic telescopic device is connected to the support seat 5 to control the height position of the support seat 5 by using the telescoping of the automatic telescopic device; the automatic telescopic device preferably adopts existing linear drive devices such as hydraulic push rods, electric push rods, cylinders, and motor screws, and is not limited thereto, as long as the linear movement of the movable end can be achieved.

[0031] The above embodiments are only illustrative of the principles and effects of the present invention and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
