Description

TECHNICAL FIELD

[0001] The utility model relates to a belt cleaning technical field, concretely relates to a belt cleaning device. BACKGROUND

[0002] The calcium carbide furnace is an industrial equipment using arc heat effect to melt furnace charge and generate calcium carbide, and the furnace charge is mainly limestone and coke. The chemical composition and characteristics of these raw materials are crucial to calcium carbide production, so the quality needs to be strictly controlled. After entering the factory, the limestone and carbon materials are stored in designated yards. The limestone needs to be pretreated by crushing and screening, and the carbon material needs to be dried and screened. Then, according to the specified ratio of the process, the limestone and carbon material are weighed and mixed uniformly to form the furnace charge, which is then transported to the top of the calcium carbide furnace by a belt conveyor. At the top of the furnace, the furnace charge is added into the electric furnace through a feeder and a hopper. To reduce the downward sliding of the furnace charge during transportation, an anti-skid conveyor belt is usually used. After completing the furnace charge transportation, there will be residual furnace charge adhering to the belt on the anti-skid conveyor belt. These residues can easily cause belt wear and failure. In the traditional way, belt cleaning mostly relies on manual operation, which is inefficient and difficult to ensure cleaning quality.

[0003] To solve the above problems, the patent with publication number CN214988314U provides a belt cleaner, which includes a main body and an adjusting steel pipe. The upper end of the main body is provided with a blade fixing frame, and the inner side of the blade fixing frame is provided with a blade. The adjusting steel pipe is arranged on the left and right sides of the main body. The outer side of the adjusting steel pipe is fixed with a fixed seat. The lower end of the fixed seat is provided with a supporting angle iron. The outer side of the supporting angle iron is connected with a pressing screw. The outer side of the pressing screw is provided with a connecting rod. The blade is fixed by the blade fixing frame. The blade is in a circular arc structure and can be attached to the belt. With the movement of the belt, the blade can scrape off the residues on the belt. However, the use of the blade in the above-mentioned patent increases the wear of the belt, thereby reducing the service life of the belt. UTILITY MODEL CONTENTS

[0018] Example

[0019] like Figures 1 to 4 The following describes a belt cleaning device: It includes an air compressor 1, a centrifugal air compressor (model ZH1800), an air pipe 2 connected to the exhaust pipe of the air compressor 1, a valve 12 on the air pipe 2, and an air chamber 3 connected to the air pipe 2. The air chamber 3 has several partitions 5 dividing it into several compartments, each compartment connected to a branch pipe 4, and each branch pipe 4 equipped with a valve 15. Both valves 12 and 15 are ball valves. Each branch pipe 4 is connected to the air pipe 2. An air outlet 14 is opened on the air chamber 3. A connecting rod 10 rotatably passes through the two side walls of the air chamber 3, and a circular handle 11 is fixedly connected to the connecting rod 10. A baffle 6 is fixed between the two connecting rods 10. The baffle 6 is located above the jet nozzle 14. A limiting component for limiting the rotation of the connecting rods 10 is provided on the air chamber 3. The limiting component includes a limiting rod 8 and several limiting blocks 7. Each limiting block 7 is fixed to the air chamber 3. Several limiting blocks 7 are evenly distributed around the connecting rods 10.
