technical field

The utility model relates to the technical field of belt cleaning equipment for belt conveyors, in particular to a coal conveying belt cleaning device.

Background technique

During the operation of the coal conveying belt, when the head cleaner does not clean the belt thoroughly enough, the coal powder adhering to the working surface of the belt in the return section will be thrown off to the equipment structure and the ground, causing dust and pollution, or adhering to the lower idler. At the surface and bearing, it will cause the belt to deviate or the roller bearing to be jammed, which will affect the stable operation of the coal conveying system.

Generally, in this working condition, it relies on manual cleaning by operators. The area is large and there are many dead corners, resulting in slow cleaning efficiency, difficulty in cleaning, and certain safety risks.

In order to solve the above technical problems, the utility model provides a coal conveying belt cleaning device, which is suitable for the belt cleaning device used in the coal dust polluted environment for a long time.

In order to achieve this technical purpose, the utility model adopts the following scheme: a coal conveying belt cleaning device, including a cleaning device and a water washing and recycling mechanism; the cleaning device includes a bracket and a scraper, the upper end of the bracket is fixedly connected with the belt conveyor structure, and the lower part of the bracket is fixed with a scraper , the upper end of the scraper is attached to the surface of the belt; the water flushing mechanism includes a flushing pipe, a water receiving tank and a return pipe, a nozzle is fixed on the flushing pipe, the nozzle is located in front of the scraper, and a water receiving tank is set under the scraper, and the water receiving tank passes through the return pipe Connected to coal bunker.

Compared with the prior art, the beneficial effect of the utility model is that: the cleaning device and the flushing water in the device work at the same time, realizes multiple cleaning, multiplies the cleaning effect, effectively prevents the belt from sprinkling coal on the return journey, reduces dust, and saves the manual cleaning process. The cleaned slime is directly discharged into the coal bunker to reduce the loss of raw coal.

The preferred scheme of the present utility model is:

The two nozzles at the end are located on the inside of the edge of the scraper, which ensures the best flushing effect and prevents the water from splashing out of the sink to cause pollution.

The bottom of the water receiving tank is inclined, and the return pipe is fixed at the lowest point of the water receiving tank to avoid partial coal slime from not flowing back.

Detailed ways

In order to fully understand the purpose, features and effects of the present utility model, the present utility model will be described in detail by the following specific embodiments, but the present utility model is not limited thereto.

Please refer to FIG. 1 and FIG. 2 , the utility model provides a coal conveying belt cleaning device, which is composed of a cleaning device and a water flushing recovery mechanism. The cleaning structure consists of a bracket 2 and a scraper 5, which is an upright scraper type. The bracket 2 is made of angle steel, the upper end of the bracket 2 is welded and fixed on both sides of the belt conveyor structure 1, and the vertical rod of the bracket 2 is provided with a through hole, which is convenient to adjust the height up and down. The scraper 5 is fastened to the lower part of the bracket 2 by bolts. The length of the scraper 5 is greater than the width of the belt 7. The disposal direction of the scraper 5 is perpendicular to the belt 7 and is attached to the surface of the belt 7. The upper end of the scraper 5 must be tightened during the operation of the belt 7. Close to the surface of the belt 7, otherwise adjust the height of the bracket 2 to make it fit, and achieve the highest cleaning effect by increasing the contact area. The scraper 5 is made of relatively soft polyurethane material, which has low friction, good wear resistance, high strength, and has a stable scraping effect, which can effectively remove the fine particles and wet sticky materials on the residual belt 7. The assembly ensures the stable contact between the scraper and the belt 7, and the automatic buffering compensates the wear of the scraper, which greatly improves the cleaning effect and facilitates on-site maintenance and replacement. Preferably, two cleaners are fixed side by side on the belt conveyor structure 1, and a water flushing and recovery mechanism is clamped on the second cleaner.

The water flushing recovery mechanism is composed of flushing pipeline 3, nozzle 4, water receiving tank 6 and return pipe 9, etc. The flushing pipeline 3 is drawn from the on-site cleaning water pipeline. It is made of stainless steel and has a diameter of DN32. It is neatly laid and installed parallel to the direction of the belt conveyor. Four detachable high-pressure nozzles 4 are arranged equidistantly in front of the cleaner according to the width of the belt 7, which is convenient for inspection and replacement, and each section is equipped with valves for easy maintenance. Among them, the two outer nozzles 4 are located at a certain distance inside the edge of the cleaner to ensure the best effect of flushing and prevent the water flow from splashing outside the water receiving tank 6 to cause pollution.

A water receiving tank 6 is arranged below the cleaner, and the bottom of the water receiving tank 6 is connected to the coal bunker 8 through a return pipe 9 . Measure the size to design and manufacture the sink 6, which is made of steel plate with a thickness of 6mm for welding, rust removal and anti-corrosion. The design length is greater than the length of the cleaner, and the width can accommodate the cleaning device. It flows into the nearby coal bunker 8 and automatically realizes coal slime recovery. The bottom of the water receiving tank 6 is an inclined surface, and the inclined surface is used to avoid partial coal slime from not flowing back. The return pipe 9 is made of a steel pipe with a diameter of 89 mm, and the position of the nozzle is selected at the lowest point of the water receiving tank 6 to facilitate the discharge of coal slime. In order to prevent the water receiving tank 6 and the inside of the pipeline from being blocked, the flushing pipeline 3 is connected to the water receiving tank 6 and the branch is connected, and the coal slime in the water receiving tank 6 is specially flushed.

The sweeper and flushing water in this device work at the same time to achieve multiple cleaning, double the cleaning effect, effectively prevent the belt from spraying coal on the return journey, reduce dust, and save the manual cleaning process. The cleaned slime is directly discharged into the coal bunker to reduce the loss of raw coal.

Finally, it should be noted that: the above enumeration is only the preferred embodiment of the present utility model, of course those skilled in the art can make changes and modifications to the present utility model, if these modifications and modifications belong to the claims of the present utility model and its equivalent technology Within the scope of the present invention, all should be considered as the protection scope of the present invention.
