Technical Field
The utility model belongs to the technical field of the belt feeder transportation, in particular to return stroke belt coal water cleans, material retrieval and utilization device.
Background
During the transportation process of the belt conveyor in a coal mine, coal dust at the bottom layer of the belt can be stuck on the surface of the belt due to high moisture content and material extrusion, and coal slime is scattered and pollutes the environment along with the vibration of the belt and the friction between the belt and a return carrier roller during the return transportation process of the belt; coal slime always adhered to the belt conveyor can continuously adhere other coal dust, and the accumulation to a certain degree can influence the normal work of the belt conveyor, even cause fault shutdown and influence the coal conveying efficiency. The coal slime is in a slurry state after being cleaned by the belt conveyor cleaner, and the viscosity is still high although the water content is high. The SS content of supernatant obtained by natural precipitation is higher, and precipitated coal is easy to harden and is not easy to clean and dispose.
The existing coal water cleaning device mainly cleans coal water on a return belt, and the recovered coal water needs to be cleaned manually and regularly, so that personnel occupation is caused, and the attractiveness of the environment is influenced.
Disclosure of Invention
The utility model aims at providing a return belt coal water cleans, material retrieval and utilization device is applied to the belt feeder and washs to solve the belt feeder and wash the problem of handling with washing waste water, reduce the processing that contains coal (ore deposit) sewage, make the material obtain make full use of, practice thrift the engineering investment.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a return belt coal water cleans, material retrieval and utilization device, includes: the device comprises a washing sweeper, a scraper sweeper, a connecting funnel, a coal water storage tank and a coal water recycling pipe, wherein the connecting funnel is positioned at the lower part of a return belt, the upper opening is provided with a support frame of the washing sweeper and the scraper sweeper, and the lower opening is communicated with the coal water storage tank; the coal water storage tank is connected with a screw pump; one port of the coal water recycling pipe is connected with the screw pump, and the other port of the coal water recycling pipe is arranged on an upper belt of the belt conveyor.
The support frame of the water washing sweeper (3) is provided with a plurality of high-pressure nozzles, and the spraying range covers the lower bottom surface of the return belt conveyor.
The washing sweeper and the scraper sweeper are respectively provided with two parts which are arranged at intervals in a staggered mode.
The connecting funnel is formed by enclosing three inclined planes and one vertical plane.
And a stirrer is arranged in the coal water storage tank.
The utility model has the advantages that the coal water cleaned from the return belt is collected and sent back to the belt conveyor, thus eliminating the loss of materials; meanwhile, the coal water cleaned by the water washing sweeper is collected into the coal water storage tank to be in a coal slurry shape and is returned to the upper side of the belt material, so that the humidity of the material is increased, and the dust settling effect to a certain degree can be achieved. The cleaned coal water is collected into the coal water storage tank along the inclined plate, a stirrer is arranged in the tank, coal is prevented from being deposited at the bottom of the storage tank, and a cleaning device is not required to be additionally arranged except for equipment maintenance. The coal water on the return belt is returned to the belt conveyor while being cleaned, so that the subsequent treatment of the part of the coal-containing sewage is avoided. The cleaning and recycling system in the form is simple and convenient to construct, low in manufacturing cost, short in construction period, convenient to operate, energy-saving and environment-friendly. The utility model discloses can combine organically with bulk cargo belt feeder such as colliery, have popularization and using value.

Detailed Description
The following describes the device for coal water cleaning and material recycling of the return belt of the present invention with reference to the accompanying drawings and embodiments.
Referring to fig. 1, the utility model is installed at the head of the belt conveyor, and the return belt passes through the water-washing cleaner 3-scraper cleaner 4-water-washing cleaner 3-scraper cleaner 4 in sequence. The coal particles attached to the return belt conveyor are washed by high-pressure water firstly, and the particles are washed down. And scraping the rest adhered particles by a scraper. The second water washing cleaner further cleans the return belt. The last scraper sweeper plays a role in scraping washing water. The cleaned coal water is received by the connecting funnel and enters the coal water storage tank. Referring to fig. 1-3, the connecting funnel is composed of three inclined surfaces and one vertical surface, wherein one inclined surface is inclined from the lower side of the belt conveyor to the bottom of the coal water storage tank, which is a main coal water receiving and conveying inclined surface, referred to as a main inclined surface. The coal water storage tank extends outwards from the bottom of the connecting funnel to the opposite side of the main inclined plane and is arranged on the ground in a square shape. The utility model discloses connect funnel and bin structure dead angle in the box that has makeed the reduction as far as possible. The agitator is arranged above the storage box to agitate the coal water in the box, so that the coal water is prevented from precipitating and separating and is in a coal slurry shape. And finally, the materials are stably conveyed back to the upper part of the belt conveyor by a screw pump, so that the materials can be reused, the humidity of the materials is increased, and the dust raising problem of the belt conveyor is reduced to a certain degree. The utility model removes the subsequent coal water treatment problem caused by the traditional sweeper.
The operation of the cleaning device of the utility model is synchronous with the operation of the belt conveyor, namely, the operation of the belt conveyor, the device of the utility model operates, and the stirrer in the coal water storage tank operates; when the belt feeder stopped operating, the utility model discloses cleaning device stopped operating. But the operation of the stirrer and the spiral pump is related to the liquid level in the coal water storage tank: when the liquid level in the tank reaches a high liquid level, starting a stirrer and a screw pump in the tank to operate, and returning the coal slurry in the tank to the position above the material of the upper belt; when the liquid level in the tank reaches the low liquid level, the screw pump and the stirrer stop working.
The example proves the advantages of the utility model structure, and has great popularization and application values.
