Description

Technical Field

[0001] The utility model relates to the technical field of coal mine machinery, and in particular to a quick dehydration device for fine sludge in underground coal mines. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when excavating geological strata rich in coal. They usually include tunnels, shafts, mining faces, etc. Coal is the main solid fuel and a type of combustible organic rock. Various tools are used in the coal mining process, including underground fine sludge rapid dehydration equipment.

[0003] The existing coal slime dehydration equipment in underground coal mines mainly adopts an intermittent working mode, which makes it impossible to achieve a continuous coal slime dehydration process. This intermittent operation mode not only limits the processing capacity of the equipment, but also makes its adaptability poor. Since the equipment needs to be started and stopped frequently during operation, this undoubtedly increases the failure rate of the equipment, thereby affecting the normal operation and production efficiency of the equipment. In addition, the existing coal slime dehydration equipment still has some problems, such as high cost, low efficiency, and long time consumption. These problems not only increase the production cost of coal mines, but also reduce the economic benefits of coal mines. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the practical embodiment clearer, the technical solution in the practical embodiment is clearly and completely described. Obviously, the described embodiment is a part of the practical embodiment, not all of the embodiments. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical.

[0018] The embodiment of the present application provides a device for rapid dehydration of fine sludge in coal mines, which solves the problems of the inability of coal slime dehydration equipment in coal mines to achieve continuous dehydration, small equipment processing capacity, poor adaptability, high failure rate, high cost, low efficiency, long time consumption, and inconvenient installation and disassembly. When used, it is realized.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-2 A coal mine underground fine sludge rapid dehydration equipment, including; a body support 12 and a gas-liquid separator 7, the body support 12 is provided with a tail roller 2, a vacuum box 4, a belt 5 and a driving roller 6, the outer rings of the tail roller 2 and the driving roller 6 are provided with a conveyor belt 14, the top of the vacuum box 4 forms a motion sealing structure with the belt 5 through a sealing ring, the top of the body support 12 is provided with a plurality of redirecting wheels 8, and the outer rings of the redirecting wheels 8 are provided with a filter cloth 1.

[0021] In a further embodiment, a material receiving hopper 3 is provided on the top of the machine body support 12 , and a material discharge inclined plate 13 is installed on the surface of the machine body support 12 and close to the driving roller 6 .

[0022] The function of the material discharge inclined plate 13 is to facilitate the falling of the separated solid matter, thereby improving the practicality of the fine sludge rapid dewatering equipment in coal mines.

[0023] In a further embodiment, a connection pipe 11 is connected to the surface of the gas-liquid separator 7 , and the other end of the connection pipe 11 extends outwardly to be connected to the vacuum box 4 , so that the gas-liquid separator 7 causes negative pressure in the vacuum box 4 .

[0024] The gas-liquid separator 7 utilizes the principles of centrifugal separation and wire mesh filtration to achieve coarse filtration to remove part of the moisture in the air, so as to reduce the working pressure of subsequent equipment. In addition, the gas-liquid separator 7 also protects the compressor by separating and preserving the liquid in the return air pipe, preventing excess refrigerant from flowing into the compressor crankcase and causing oil dilution.

[0025] In a further embodiment, a cloth pressing roller 10 is arranged on the top of the machine body support 12, and the cloth pressing roller 10 presses down the adhesive tape 5 and the filter cloth 1 tightly.

[0026] The main function of the cloth pressing roller 10 is to guide and press the coal slime cake. The cloth pressing roller 10 helps to evenly distribute the coal slime cake on the conveyor belt 14 and ensure that it can fit tightly between the conveyor belt 14 and the filter cloth 1 during the vacuum filtration process, thereby improving the dehydration efficiency. In addition, the cloth pressing roller 10 can also help adjust the tension of the coal slime cake in the running direction to ensure that it passes through the equipment steadily and smoothly.

[0027] In a further embodiment, a scraper 9 is installed on the surface of the body bracket 12 , and the scraper 9 is made of high-strength alloy steel.

[0028] The main function of the scraper 9 is to scrape the coal sludge cake on the conveyor belt 14 to help it dehydrate better, and the scraper 9 has wear resistance and corrosion resistance, so that the scraper 9 can still maintain good working condition and performance when facing harsh working environment and continuous wear.

[0029] In a further embodiment, a plurality of water outlet holes are formed on the surface of the conveyor belt 14 .

[0030] The main function of the conveyor belt 14 is to transport the sludge and coal slime cakes from one place to another. The conveyor belt 14 will first collect the sludge and dehydrate it to convert it into coal slime cakes. In this process, the function of the water outlet is to discharge excess water from the coal slime cakes to achieve a better dehydration effect.

[0031] In a further embodiment, the vacuum box 4 is configured to be in the shape of a long groove, and the vacuum box 4 is integrally formed of PP material.

[0032] The main function of the vacuum box 4 is to help achieve rapid and continuous dehydration of the mud, thereby improving the working efficiency of the fine sludge rapid dehydration equipment in coal mines and improving the practicability of the equipment.

[0033] During use, the driving roller 6 and the gas-liquid separator 7 are started by the controller, and materials are added through the receiving hopper 3. The driving roller 6 drives the conveyor belt 14 to rotate, and the vacuum box 4 and the tape 5 form a moving seal structure. Water is injected between the rubber seals, and the water tension is used to seal. Through the use of the gas-liquid separator 7, the vacuum negative pressure absorbs the moisture in the coal slime, which can complete the functions of automatic dehydration and slag unloading, and finally the solid matter is scraped off by the scraper 9.

[0034] By absorbing moisture from the coal slime through vacuum negative pressure, it can complete functions such as automatic dehydration and slag unloading.

[0035] In summary, compared with the prior art, the invention has the following beneficial effects: the underground fine sludge rapid dehydration equipment of coal mines realizes a large processing capacity through the coordinated use of filter cloth 1, tail roller 2, vacuum box 4, tape 5, drive roller 6, gas-liquid separator 7 and connecting pipe 11, and can process a large amount of coal sludge in a short time to meet the production needs of coal mines. It is suitable for various types of coal sludge and has good dehydration effect and reliability stability. The equipment does not require extrusion action to reduce the degree of wear. The filter cloth 1 material is wear-resistant and tensile-resistant, with a long service life. There is no need to replace the filter cloth 1, which reduces maintenance costs, realizes continuous operation, and improves production efficiency.
