Description

Technical Field

[0001] The invention relates to the technical field of coal conveying equipment in power plants, and in particular to a novel coal conveying belt cleaning device in power plants. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor. It is available in fixed and mobile types with simple structure and high efficiency. It is a continuous conveying machinery with flexible conveyor belt as material carrying and traction component. The friction between the drive roller and the conveyor belt is used to drag the conveyor belt and materials to run. During the use of the coal conveyor belt, when the moisture content of the coal is high, the coal powder is easy to adhere to the outside of the conveyor belt in the form of mud, making it difficult to clean. Long-term operation will have an adverse effect on the operation of the conveyor equipment itself. For this reason, a belt cleaning device is required.

[0003] An existing coal conveyor belt cleaning and dust removal device for a thermal power plant (publication number: CN221564649U) has at least the following disadvantages: when the device flushes and cleans the bottom of the belt, it is unable to centrally collect the swept coal powder and wastewater, causing the coal powder and wastewater to fall into the work site, thereby increasing subsequent cleaning work, and the wastewater is not effectively recycled and reused, resulting in a waste of water resources. For this reason, the present invention is proposed. Summary of the invention

[0009] As a further solution of the present invention, a filter screen is fixed to the top surface of the isolation plate, and the right side of the filter screen is also fixed to the inner right side of the collection box.

[0010] As a further solution of the present invention, a connecting frame is fixed to the top surface of the filter screen, a brush strip is fixed to the bottom surface of the connecting frame, the bottom surface of the brush strip is in contact with the top surface of the filter screen, an electric push rod is fixed to the right side of the collecting box, an extension hole is opened on the right side of the collecting box, one end of the telescopic rod of the electric push rod passes through the extension hole and is fixed to the right side of the connecting frame.

During the rotation of the fitting roller, the cleaning roller rotates in the direction opposite to the forward direction of the belt, so that the cleaning roller cleans the coal powder stuck to the bottom surface of the belt. During this process, the fitting roller rotates in the forward direction of the belt and blocks and limits the coal powder swept by the cleaning roller, so that the cleaned coal powder is collected in the first cavity of the collecting box to prevent the coal powder from falling into the workplace and becoming inconvenient to handle.

[0018] By starting the water pump, water inside the collection box can be extracted and sprayed onto the bottom surface of the belt through the atomizing nozzle, so that the cleaning roller can better clean the belt, and the waste water after cleaning is filtered through the filter net and recovered to the second cavity of the collection box for easy recycling and reuse.

[0019] The blocking roller cooperates with the laminating roller to shield both sides of the cleaning pipe, preventing the water sprayed from the atomizing nozzle from splashing out of the collection box and causing pollution to the workplace. BRIEF DESCRIPTION OF THE DRAWINGS
