Description

A return belt coal water cleaning and material recycling device

technical field

The invention belongs to the technical field of belt conveyor transportation, in particular to a return belt coal water cleaning and material recycling device.

Background technique

During the transportation of coal mines on the belt conveyor, due to the high moisture content and the extrusion of materials, the pulverized coal at the bottom of the belt will stick to the surface of the belt. During the return transportation of the belt, with the vibration of the belt and the The friction of the return rollers caused the coal slime to spill and pollute the environment; the coal slime that has been adhering to the belt conveyor will continue to stick to other coal dust, and the accumulation to a certain extent will affect the normal operation of the belt conveyor and even cause failure Downtime will affect the efficiency of coal transportation. The coal slime is in slurry form after being cleaned by the belt conveyor cleaner. Although the water content is high, the viscosity is still relatively high. The SS content of the supernatant obtained by natural precipitation is also often high, and the precipitated coal is easy to compact, and it is difficult to clean and dispose.

The existing coal water cleaning device mainly cleans the coal water on the return belt. However, the recovered coal water needs to be manually cleaned regularly, which causes the occupation of personnel and affects the appearance of the environment.

Contents of the invention

The purpose of the present invention is to provide a return belt coal water cleaning and material recycling device, which is applied to belt conveyor cleaning to solve the problems of belt conveyor cleaning and cleaning wastewater disposal, reduce the treatment of coal (mine) sewage, and make materials obtain Make full use of and save engineering investment.

In order to achieve the above object, the technical solution adopted by the present invention is: a return belt coal water cleaning and material recycling device, including: water washing cleaner, scraper cleaner, connecting funnel, coal water storage tank and coal water reuse pipe , the connecting funnel is located at the lower part of the return belt, the upper port is provided with the support frame of the washing cleaner and the scraper cleaner, and the lower port is connected to the coal water storage tank; the coal water storage tank is connected with a screw pump; One port of the water return pipe is connected to the screw pump, and the other port is set on the upper belt of the belt conveyor.

The supporting frame of the water cleaning cleaner (3) is provided with several high-pressure nozzles, and the injection range covers the bottom surface of the return belt conveyor.

There are two water cleaning cleaners and scraper cleaners respectively, and they are installed at staggered intervals.

The connecting funnel is surrounded by three inclined surfaces and one vertical surface.

A stirrer is arranged in the coal water storage tank.

The effect of the present invention is that the coal water cleaned from the return belt is returned to the belt conveyor after being collected, eliminating the loss of materials; at the same time, the coal water cleaned by the washing cleaner is collected into the coal water storage tank to form a coal slurry shape, and return to the top of the belt material, which increases the humidity of the material and can play a role in dust reduction to a certain extent. The cleaned coal water is collected along the sloping plate into the coal water storage tank, and an agitator is installed in the tank to avoid coal deposition at the bottom of the storage tank, and no additional cleaning device is required except for equipment maintenance. The coal water on the return belt is returned to the belt conveyor while being cleaned, which eliminates the subsequent treatment of this part of the coal-containing sewage. This type of cleaning and recycling system has the advantages of simple construction, low cost, short construction period, convenient operation, energy saving and environmental protection. The invention can be organically combined with bulk cargo belt conveyors such as coal mines, and has great popularization and application value.

Detailed ways

A return belt coal water cleaning and material recycling device of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Please refer to Fig. 1, the present invention is arranged on the head of the belt conveyor, and the return belt passes successively through the washing cleaner 3-scraper cleaner 4-water washing cleaner 3-scraper cleaner 4. The coal particles attached to the return belt conveyor are first washed by high-pressure water, and the next part of the particles will be washed. Then scrape off the rest of the attached particles by the scraper. The second water wash cleaner will further clean the return belt. The last scraper cleaner also plays the role of scraping off the flushing water. The cleaned coal water is received by the connecting funnel into the coal water storage tank. Please refer to Figure 1-3, the connecting funnel is composed of three slopes and one vertical surface, one of which slopes from the bottom of the belt conveyor to the bottom of the coal water storage tank, which is the main coal water receiving and conveying slope, referred to as the main slope. The coal water storage tank extends laterally from the bottom of the connecting funnel to the main slope, and is placed on the ground in a square shape. The structure of the connection funnel and the storage box of the present invention reduces the dead angle in the box as much as possible. A stirrer is set above the storage tank to stir the coal water in the tank to avoid coal water precipitation and coal water separation, so that the coal water is in the form of coal slurry. Finally, the screw pump smoothly transports the material back to the top of the upper belt conveyor, so that the material can be reused, and the humidity of the material is increased, which reduces the dust problem of the belt conveyor to a certain extent. The invention avoids the follow-up coal water treatment problem caused by the traditional sweeper.

The operation of the cleaning device of the present invention is synchronized with the operation of the belt conveyor, that is, when the belt conveyor is running, the device of the present invention is running, and the agitator in the coal water storage tank is running; when the belt conveyor stops running, the cleaning device of the present invention stops running. However, the operation of the agitator and the screw pump is related to the liquid level in the coal-water storage tank: when the liquid level in the tank reaches a high level, the agitator and the screw pump in the tank will start to run, and the coal slurry in the tank will be sent back to the top of the material on the upper belt ; When the liquid level in the tank reaches a low level, the screw pump and agitator stop working.

This example has proved the advantage of this utility model structure, has great popularization and application value.
