Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal, and in particular relates to a dust removal device for a belt conveyor. Background Art

[0002] The belt conveyor is a commonly used equipment in coal preparation plants. The belt conveyor of Donglutian Coal Preparation Plant is affected by the inclination angle and height difference of the chute. The high-speed falling coal flow compresses the air in the chute to produce airflow, which intensifies the powder spraying at the outlet of the guide chute and generates a large amount of dust, which seriously restricts the on-site standardized improvement work, affects the health of workers, increases the labor intensity on site and poses a safety hazard of coal dust explosion accidents. Therefore, a belt conveyor dust removal device is needed to solve the above problems. Utility Model Content

[0003] The utility model aims to provide a dust removal device for a belt conveyor to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a dust removal device for an adhesive tape machine, comprising a base plate, a tape machine is arranged on the base plate, a material guide frame is fixedly arranged on the adhesive tape machine, a dust collecting hood is connected to the material guide frame, and an air suction pipe is connected to the dust collecting hood, a recovery frame is fixedly arranged on the base plate, a suction fan is connected to the recovery frame, the top of the suction fan is connected to the air suction pipe, a filter box is connected to one side of the recovery frame, an air outlet pipe is connected to one side of the filter box, a plurality of dust suppression units are arranged in the material guide frame, a spray box is fixedly arranged on the base plate, a spray pipe is connected to one side of the spray box, a spray pump is arranged on the spray pipe, one end of the spray pipe passes through one side of the material guide frame and extends to the interior of the material guide frame, one end of the spray pipe is fixedly arranged in the material guide frame, a plurality of spray nozzles are connected to one side of the spray pipe, and a blocking curtain is arranged on one side of the material guide frame.

[0005] By setting the above structure, first, under the operation of the suction fan, the dust transported by the belt conveyor can be absorbed by the dust collecting hood at one end of the suction pipe, and finally transported to the recovery frame for storage. During this period, under the operation of the spray pump, the water in the spray box is extracted through the spray pipe and sprayed out through the spray nozzle. The spray will be mixed with the dust and absorbed by the dust collecting hood, which will help the sucked dust to settle quickly, and then it is convenient for storage in the recovery frame. When the dust flows in the material guide frame, it will be blocked by the dust suppression unit and the flow rate will be slowed down, which can prevent the dust from being sprayed out from the front end of the material guide frame. Combined with the blocking of the curtain and the spray guidance of the spray nozzle, most of the dust in the material guide frame can be sucked away at the dust collecting hood, thereby reducing the dust output at the front outlet of the material guide frame, suppressing the dust source, reducing the on-site coal dust density, alleviating the labor intensity of on-site personnel, creating a healthy working environment for employees, and having strong practicality.

[0006] As a preferred embodiment, the spray pipe is located on one side of the curtain.

[0007] As a preferred embodiment, the spray nozzle is located in the material guiding frame.

[0008] As a preferred embodiment, the spray pipe is located above the adhesive tape machine.

[0009] As a preferred embodiment, the size of the dust collecting hood is adapted to the size of the upper surface of the material guiding frame.

[0010] As a preferred implementation, the barrier curtain covers a portion of the space in the material guiding frame.

[0011] By arranging the spray tube on one side of the barrier curtain, the barrier curtain can block the air outlet on one side of the spray tube, thereby reducing the influence of external wind force on the front side of the material guide frame on the spray of the spray nozzle, and because the spray nozzle and the spray tube are close to the barrier curtain, the person only needs to open the barrier curtain to conveniently check the spray blockage of the spray nozzle and the damage of the barrier curtain, which makes it convenient to repair and replace it.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a suction fan, firstly, under the operation of the suction fan, the dust transported by the belt conveyor can be absorbed by the dust collecting hood at one end of the suction pipe, and finally transported to the recovery frame for storage. During this period, under the operation of the spray pump, water in the spray box is extracted through the spray pipe and sprayed out through the spray nozzle, the spray will be mixed with the dust and absorbed by the dust collecting hood, thereby helping the sucked dust to settle quickly, and thus facilitate storage in the recovery frame. When the dust flows in the material guide frame, it will be blocked by the dust suppression unit and the flow rate will be slowed down, which can prevent the dust from being sprayed out from the front end of the material guide frame. Combined with the blocking of the curtain and the spray guidance of the spray nozzle, most of the dust in the material guide frame can be sucked away at the dust collecting hood, thereby reducing the dust output at the front outlet of the material guide frame, suppressing the dust from the source, reducing the on-site coal dust density, alleviating the labor intensity of on-site personnel, creating a healthy working environment for employees, and having strong practicality.

[0014] The utility model arranges the spray pipe on one side of the barrier curtain so that the barrier curtain can block the air outlet on one side of the spray pipe, thereby reducing the influence of the external wind force on the spray of the spray nozzle at the front side of the material guide frame. Moreover, since the spray nozzle and the spray pipe are close to the barrier curtain, the spray blockage of the spray nozzle and the damage of the barrier curtain can be conveniently checked by manually opening the barrier curtain, thereby facilitating the maintenance and replacement of the barrier curtain.
