Apparatus and method for wash separating coal by jump separation

[0044] Example 1, figure 1 , An air chamber gangue discharge jig machine, which includes an existing single-stage jig machine 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. The discharge channel 4 is a closed device with an upper opening, which is composed of an inlet 3, a connecting channel 10, and a clean coal discharge outlet 11. The inlet 3 of the discharge channel 4 is similar to the existing single-stage jig The overflow port of the machine body 1 is adapted and connected with the periphery in a sealed manner, and it can also be used as a common port on the same wall. The uppermost part of the discharging channel 4 is a rectangular parallelepiped shape, 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, the cross-section can be rectangular, round, o

[0048] Example 2, in figure 2 Among them, another type of air chamber waste removal jigging machine, the shape, structure, materials used, and functions of the single-stage jigging machine body 1 are as described in the first embodiment. The main shape, structure, materials, functions, etc. of the discharge channel 4 are also as described in Example 1, the difference is that the figure 1 The top water device 7 of the single-stage jig machine body 1 mentioned in the above is eliminated, and a water supplement device 13 with an adjustable supplemental water flow rate is added at a certain position on the upper part of the single-stage jig machine body 1 near the middle and rear. The installation direction of the water replenishing device 13 is convenient for operation, and it can be either on the left or right side of the body 1 of the single-stage jigger.

[0049]When this embodiment works, the working steps, methods, principles, etc. are as described in embodiment 1, the difference

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

[0051] Based on the same principle and method, the present invention can also be used as image 3 The structure and function described are realized on the gangue removal jig as described in the second embodiment.

[0052] When this embodiment works, 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 by the installed discharge height adjustment device 14 that can adjust the discharge heig
