Embodiment 1

[0045] as attached figure 1 As shown in 6, the present invention comprises a low-pressure gas storage tank 1, a main water pipe 2, a gangue part that is communicated with the low-pressure gas storage tank 1 and the main water pipe 2 respectively, and a medium coal part that is communicated with the low-pressure gas storage tank 1 and the main water pipe 2 respectively. and the secondary clean coal part respectively communicated with the low pressure gas storage tank 1 and the main water pipe 2, the gangue part is connected with the medium coal part, and the medium coal part is connected with the secondary clean coal part. The low pressure air storage tank 1 can supply compressed air to the gangue part, the medium coal part and the secondary clean coal part respectively, and the main water pipe 2 can respectively provide all the water for coal washing to the gangue part, the medium coal part and the secondary clean coal part.

[0046] The gangue part includes a gangue box 3, a ...

Embodiment 2

[0059] as attached figure 1 As shown in -6, based on Embodiment 1, the number of the ventilation pipes is two, which can facilitate the discharge and discharge of the gas in the gangue box 3.

Embodiment 3

[0061] as attached figure 1 As shown in -6, based on Embodiment 1 and Embodiment 2, there is a gap between the outer side wall of the tightly closed cylinder 27 and the annular tightly closed cavity 26 . It can prevent the outer side wall of the tightly closed cylinder 27 and the annular closed cavity 26 from being worn, and reduce the noise caused by the swirling of the air flow.

[0062] For the convenience of control, butterfly valves for controlling airflow may be provided on the ventilation pipes in Embodiment 1, Embodiment 2 and Embodiment 3, respectively.

[0063] At present, the technical solution of the present application has undergone a pilot test, that is, a small-scale experiment of the product before mass production; after the pilot test is completed, a user usage survey has been carried out in a small area, and the survey results show that the user satisfaction is high; Now it has started to prepare for the formal production of the product for industrialization...

Abstract

The invention relates to a coal dressing jigger with a numerical control air bellow easy to adjust. The coal dressing jigger comprises a low-pressure air storage tank, a main water pipe, a gangue part communicated with the low-pressure air storage tank and the main water pipe, a middling coal part communicated with the low-pressure air storage tank and the main water pipe and a secondary clean coal part communicated with the low-pressure air storage tank and the main water pipe. The gangue part is connected with the middling coal part, and the middling coal part is connected with the secondary clean coal part. The low-pressure air storage tank can provide compressed air for the gangue part, the middling coal part and the secondary clean coal part, and the main water pipe can provide all water for coal washing for the gangue part, the middling coal part and the secondary clean coal part.

Description

technical field [0001] The invention relates to a coal preparation jig with an easily adjustable numerical control air box. Background technique [0002] Coal preparation jig refers to the equipment that realizes the jigging process. The material is mainly in the process of sorting according to the density difference in the variable-speed medium flow that rises and falls vertically. The difference in particle size and shape of the material has a certain influence on the beneficiation result. [0003] Existing document CN212040954U, an anti-stick blocking jig for raw coal sorting, including a jig body, the jig body is fixed on a support frame, and a feeding pipe is fixedly installed on the upper end of the jig body, so the The jig body includes a discharge slag channel, and a slag discharge port is fixed at the bottom end of the discharge slag channel. The discharge slag channel includes two elastic plates, and the elastic plates are connected to the jig body through the re...
