Description

Technical Field

[0001] This invention belongs to the field of conveyor belt technology, specifically relating to a cleaning and water removal device for a conveyor belt. Background Technology

[0002] Tubular belt conveyors, also known as tubular belt conveyors, are widely used in industries such as power, building materials, chemicals, metallurgy, mining, ceramics, papermaking, coal, ports, and grain. The main advantage of tubular belt conveyors is that there is no flying or splashing of loose materials, making them safer and more environmentally friendly. The conveyor belt is rolled into a cylindrical shape, and the belt bearing surface is wrapped inside, which avoids the scattering of residual materials adhering to the belt along the return conveying line.

[0003] Most existing conveyor belt systems operate in outdoor environments. If dust from the conveyed material or rainwater from rainy weather enters between the idler rollers and the belt, the friction coefficient of the contact surface between the idler rollers and the belt will decrease, making it impossible to effectively transmit belt tension. This can easily lead to abnormal operating conditions such as belt slippage and twisting, seriously affecting the safe operation of the conveyor belt system. Summary of the Invention

[0004] To address the above issues, this invention presents a belt cleaning and dewatering device for a conveyor belt system. By adding a cleaning brush roller device and an air-blowing drying device between the idler roller group and the belt of the existing conveyor belt system, water stains on the circular pipe section of the conveyor belt system can be effectively removed, ensuring the stability of the conveyor belt system operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveyor belt cleaning and dewatering device for a tubular conveyor includes a frame, several transverse partitions spaced apart in the middle of the frame, several idler roller groups correspondingly arranged on the transverse partitions, and a conveyor belt wound into a cylindrical shape and arranged between each idler roller group. Each transverse partition has through holes for the conveyor belt to pass through. Each idler roller group includes multiple idler rollers arranged around the through holes. The device also includes at least one set of cleaning and dewatering devices for cleaning and drying the outer surface of the conveyor belt. Depending on the amount of dust and water stains in the working environment of the tubular conveyor and the length of the conveyor belt, one or more cleaning and dewatering devices can be selectively installed along the outer side of the conveyor belt.

[0007] The cleaning and dewatering device includes a cleaning device and a drying device. The cleaning device includes multiple brush rollers that cooperate to form an annular surround for cleaning the outer surface of the conveyor belt. The two ends of the brush rollers are rotatably connected to the cross partition through a mounting frame, and the bristles of the brush rollers are in frictional contact with the outer surface of the conveyor belt. The drying device includes an annular air duct that forms an annular surround for the outer surface of the conveyor belt. The annular air duct is fixedly connected to the cross partition through an air duct frame. One end of the annular air duct is a blind end, and the other end serves as an air inlet for external compressed air. Several air outlets are arranged on the pipe wall of the annular air duct facing the conveyor belt.

[0008] Furthermore, the frame is a horizontal frame structure with a rectangular cross-section, and several horizontal partitions are preferably vertically fixed at equal intervals in the middle of the frame. In order to enhance the mechanical strength of the horizontal partitions, structural frames and reinforcing ribs are added to their edges and the middle.

[0009] Furthermore, each of the transverse partitions has two through-holes, which serve as the upward and downward access points for the conveyor belt, respectively. The upward access point is located directly above the downward access point, and the idler roller assembly is positioned on the side of the through-holes facing the direction of the conveyor belt's movement.

[0010] Furthermore, the air inlet of the annular duct is also equipped with a heater for heating compressed air. The compressed air can be heated according to actual needs. For example, in rainy or snowy weather or when the ambient temperature is low, water vapor in the air or moisture in the compressed air may form condensation stains on the outer surface of the conveyor belt. Hot air helps to quickly dry the residual rainwater or water stains, improving the efficiency and effect of dewatering and drying the conveyor belt.

[0011] Furthermore, a central roller shaft is rotatably mounted in the middle of the brush roller, and the mounting frame is a U-shaped bracket. Adjustable elongated holes are opened on both sides of the mounting frame, and the two ends of the central roller shaft move out through the two corresponding adjustment elongated holes. The two ends of the central roller shaft are adjustablely connected to the mounting frame through tension adjustment screws, which can realize the adjustment of the proximity distance between the brush roller and the conveyor belt. According to the actual cleaning needs, the cleaning force of the bristles can be adjusted appropriately, and it can also adapt to the installation needs of conveyor belts with different pipe diameters.

[0012] Furthermore, multiple horizontal partitions are spaced between two adjacent sets of cleaning devices, and multiple horizontal partitions are also spaced between two adjacent sets of drying devices. The cleaning devices and drying devices are installed in groups, with the drying devices belonging to the same group installed downstream of the cleaning devices.

[0013] As a preferred embodiment, the idler roller group includes six idler rollers arranged in a regular hexagonal pattern; the cleaning device includes six brush rollers, which are also arranged in a regular hexagonal pattern corresponding to the six idler rollers, and all six brush rollers are located on the side of the through-hole opening opposite to the direction of travel of the conveyor belt. Of course, each idler roller group and brush roller group can also consist of eight or more idler rollers.

[0014] As another preferred embodiment, the roller assembly includes six rollers, and the cleaning device includes six brush rollers. The six rollers and six brush rollers, installed on the same through-hole, are arranged in an alternating pattern. Three rollers and three brush rollers are installed on each side of the through-hole, and each roller and brush roller is arranged in an equilateral triangle. Alternatively, multiple brush rollers can be installed on multiple crossbeams in a spiral arrangement.

[0015] The present invention also includes other components that enable its normal use, all of which are conventional means in the art. In addition, devices or components not limited in the present invention, such as the drive device of the conveyor belt machine, the external compressed air pipeline network, the brush roller and the tension adjustment screw, all adopt the prior art in the art.

[0016] The beneficial effects of this invention are as follows:

[0017] The conveyor belt cleaning and dewatering device provided by this invention effectively removes dust and water stains from the outer surface of the conveyor belt by adding a cleaning brush roller device and an air drying device to the cross plate of the conveyor belt without changing the original structure of the conveyor belt. It can effectively avoid problems such as conveyor belt slippage and twisting that exist in the operation of existing conveyor belts, and ensure the stability of the conveyor belt operation. Moreover, the cleaning and dewatering device is simple and convenient to install and maintain, which helps to save the cost of equipment modification. Attached Figure Description
