Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and draining of adhesive tape for belt conveyors, in particular to a regular cleaning and draining device of adhesive tape for belt conveyors. Background Art

[0002] With the development of the times, users have higher and higher requirements for belt conveyors in terms of low carbon, high efficiency, environmental protection and energy saving. The traditional way to clean and discharge the return belt of a belt conveyor is to use a large amount of water to flush, then the spiral conveys the sludge mixture to the sewage funnel, and the sewage is led to the zero-meter layer pump pit through the welded sewage pipe.

[0003] On the one hand, large-volume flushing causes waste of water resources and increases energy consumption; on the other hand, the pipelines in the on-site transfer station are complicated, with various types of pipelines crisscrossing each other. The sewage pipelines are generally not effectively arranged at a large angle, and the inclination angle is too gentle, and there are even long horizontal pipelines. As a result, after the horizontal pipeline has been running for a period of time, the coal sludge will gradually accumulate in the lower part of the pipeline, which will cause pipeline blockage in severe cases. Once blocked, the difficulty of dredging and the subsequent maintenance of equipment are very large, which will inevitably cause the coal sludge inside the cleaning machine to be unable to be discharged and forced to withdraw from operation, and the return belt surface of the belt conveyor cannot be effectively cleaned. This will not only increase the cost of enterprise operation and environmental protection, but also pose a serious threat to the health of on-site operators.

[0004] The spiral sewage discharge device commonly used in the market for sewage cleaning machines consumes a lot of water. At the same time, it is affected by the layout angle of the sewage pipe. There is a risk of pipe blockage after long-term operation. The workload of dredging and maintenance is large. In serious cases, the cleaning machine is even forced to stop running, which greatly increases labor costs. In addition, there are some water recycling solutions, but the structure is very complicated, some even take up a lot of space, the cost is too high, and it is not suitable for practical application and large-scale promotion. Moreover, in actual applications, there are still many cases where sewage cleaning and sewage discharge rely on manual labor. Summary of the invention

The sewage tank is provided with a periodic sewage discharge mechanism that can discharge sludge mixture.

[0008] Preferably, the first sewage pump is arranged on the side cover plate of the clean water tank; and the float valve is arranged on the side plate of the clean water tank.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In the description of this application, when a feature is referred to as being "set", "fixed" or "connected" to another feature, it may be directly set, fixed or connected to the other feature, or indirectly set, fixed or connected to the other feature.

[0026] The present application is a regular sewage discharge device for a belt conveyor belt cleaning structure, which belongs to the belt cleaning and washing system of the belt conveyor and is located below the return belt. Generally, the belt cleaning and washing system is interlocked with the belt conveyor signal and put into operation synchronously. The working surface of the return belt passing through the cleaning machine is fully in contact with the water softening roller and the scraper of the cleaning system. Then, the water for cleaning the belt begins to spray evenly on the belt surface through the nozzle, so that the adhesion on the working surface of the belt is washed and softened, and then gradually cleaned by the scraper of the cleaning system to achieve the purpose of cleaning the working surface of the belt.

[0027] In the prior art, the cleaned sludge and excess water generally enter the collection box below the equipment, and then are discharged at a fixed point by the spiral sewage system, which consumes a lot of water, has a high risk of clogging, and consumes a lot of energy. The present application provides a new solution for the sewage discharge device for belt conveyor cleaning with a tape, which occupies a small space, can ensure the effectiveness and reliability of sewage discharge, and can also achieve regular sewage discharge and sewage recycling.

The clean water tank is provided with a first sewage pump 1 and a float valve 2, and the sewage tank is provided with a periodic sewage discharge mechanism that can discharge the sludge mixture. The overall structure forms a water balance system.

[0030] Specifically, the first sewage pump 1 is a submersible sewage pump, which serves as the power source of the water balance system, supplies water for belt cleaning and sewage tank self-flushing, so that sewage can be recycled; the float valve 2 can automatically replenish water through the float to detect the water level in the clean water tank to ensure the balance of the entire water circulation system.

[0031] More specifically, the float valve 2 is externally connected to a water supply pipe, and the use of the float valve 2 to automatically control the water level is convenient, effective, and low-cost; when the water level is low, external water is allowed to flow into the clean water tank; when the water level reaches a certain height, the float rises, driving its switch contacts to disconnect, stopping the water pump or valve, and preventing the water from continuing to flow into the clean water tank.

At the same time, the screw lift 4 is used in conjunction with a PLC, and the PLC is electrically connected to the screw lift 4. The staff can set the lifting speed and frequency of the screw lift 4 through the PLC, that is, according to the actual working conditions of the equipment, set or modify the appropriate time interval to regularly start and pull up the piston for sewage discharge. This is a common control connection form, which will not be elaborated here.
