Problems solved by technology

[0002] In the middle of the 20th century, Germany developed a mechanical dynamic sieve jig to replace the manual selection of large pieces of gangue. In the 1980s, a similar dynamic sieve jig was developed in China to solve the separation of 50mm-300mm large lumps of coal. , but so far this method and equipment still have the shortcomings of large investment, complicated equipment manufacturing, and poor reliability, and the problem has not been solved
That being the case, why hasn't the air pulsation jig been used to discharge gangue for so many years? This is because, up to now, the traditional single-stage jig and its coal preparation method for coal preparation at home and abroad are like the book "Mineral Processing" published by China University of Mining and Technology Press in October 2002. 192-226 Page 329-435 of the book "Coal Preparation Handbook" published by China Coal Industry Press in April 1993, it is necessary to add a large amount of water to loosen the bed and convey stratification The result is that the power consumption is extremely large, and because a large amount of water and light products are mixed and discharged together, the basic links of the whole system are increased, the whole system is complicated, and the investment is large. There is no advantage over

Embodiment 1

[0044] Example 1, figure 1 Among them, an air chamber gangue-discharging jig, which includes an existing single-stage jig body 1 and a discharge channel 4. The inclination angle of the sieve plate 5 in the single-stage jig machine body 1 is larger than conventional ones. The discharge channel 4 is a closed device with an upper opening, and is composed of a feed port 3, a connecting channel 10 and a clean coal discharge port 11. The feed port 3 of the discharge channel 4 is connected to the existing single-stage jigging The overflow port of the machine body 1 is adapted, and the periphery is sealed and connected, and it can also be made as a common port of the same wall. The uppermost part of the discharge channel 4 is in the shape of a cuboid, and the lower part is a cylindrical connecting channel 10 . The connecting channel 10 can be straight, can also be made into various bends, can also be made into oblique or other forms, and the section can be rectangular, circular, or ...

Embodiment 2

[0048] Example 2, in figure 2 Among them, another air chamber gangue-discharging jig, the shape, structure, materials used, and functions of the single-stage jig body 1 are as described in Example 1. The main shape, structure, materials used, effect, etc. of the discharge channel 4 are also as described in Embodiment 1, and the difference is that figure 1 The top water device 7 of the single-stage jig body 1 described in the above is canceled, and a water replenishment device 13 with an adjustable water flow rate is installed on the upper part of the single-stage jig body 1 near the middle and rear. The installation direction of replenishment device 13 is advisable with easy operation, can be on the left side of single stage jig machine body 1 or right side.

[0049]When this embodiment is working, the working steps, methods, principles, etc. are as described in Embodiment 1, the difference is that a certain amount of water is added to the single-stage jig body 1 through the...

Embodiment 3

[0050] Example 3, in image 3 Among them, the third type of air chamber gangue jigging machine, the shape, structure, materials used, and functions of the single-stage jigging machine body 1 are as described in Embodiment 1. The main shape, structure, materials used, and functions of the discharge channel 4 are also as described in Embodiment 1. The difference is that a discharge height adjustment device 14 that can adjust the discharge height is installed on the feed inlet 3. .

[0051] Based on the same principle and method, the present invention can also image 3 The structure and function are realized on the gangue-discharging jig as described in Embodiment 2.

[0052] When this embodiment is working, the working steps, methods, principles, etc. are as described in Embodiment 1, the difference is that the ash content of the discharged clean coal is controlled to a certain extent through the installed discharge height adjusting device 14 that can adjust the discharge heig...

Abstract

A jig washing method and its apparatus for removing coal gangue feature that the overflow channel of existing single-segment jig washer is reformed for only discharging light product, the inclination of sieving board is increased, the water supplementing unit is additionally used, and the depth of bed layer is increased. Its advantages are high effect to separate 3 products at same time, and less consumption of water and electric energy.

Description

Technical field [0001] The invention relates to a coal preparation method and coal preparation equipment thereof, in particular to a jigging method for removing gangue and a jigging machine for removing gangue. Background technique [0002] In the middle of the 20th century, Germany developed a mechanical dynamic sieve jig to replace the manual selection of large pieces of gangue. In the 1980s, a similar dynamic sieve jig was developed in China to solve the separation of 50mm-300mm large lumps of coal. , but so far this method and equipment still have the disadvantages of large investment, complicated equipment manufacturing, and poor reliability, and the problem has not been solved. From the perspective of the entire development history of the jigging machine, the dynamic sieve jigging machine is the oldest type of jigging machine. The development of the jigging machine has gone through "dynamic sieve"→"piston"→ In the process of "air pulsation", the current "air pulsation...
