Problems solved by technology

However, after long-term practice and observation, it is found that so far, the pulsating water flow of no jig machine is truly vertically alternating.
This is the root cause and defect of jig sorting accuracy is not high

Embodiment 1

[0022] Such as Figure 1 to Figure 4 As shown, taking the SKT type jig as an example, a Fengshui uniform configuration structure for the jigging coal washing machine in the under-screen air chamber, including a partition 1, the air chamber 2 is divided into lengths by the partition 1 according to the width of the slot Two sections of compartments 4 are equal, and the divider channel 10 formed by welding the partition plate 1 and the two sides of the air chamber 2 connects the inlet 3 of the air chamber with the compartment 4; at the same time, the inlet of the air chamber 3 is divided into two openings with equal areas, so that the wind and water coming in from the air chamber inlet 3 can be evenly distributed across the entire width. The wind coming in from the air chamber inlet 3 is provided by the bellows 9 . In this embodiment, a deflector 6 is provided in the ascending channel 5 of the coal washer, which divides the rising pulsating water flow from the air chamber 2 into...

Embodiment 2

[0024] Such as Figure 5 to Figure 8 As shown, taking the YT-type jig as an example, it is a feng shui uniform configuration structure for a compound jigging coal washing machine, including two partitions 1, and the air chamber 2 is separated by two partitions 1 according to the width of the machine slot. It is two sections of compartments 4 with equal length, and the shunt channel 10 formed by the two partitions 1 and the two sides of the air chamber 2 connects the inlet 3 of the air chamber and the compartment 4; The air chamber inlet 3 is divided into two openings with the same area. One of the two openings is a rhombus opening, and the other opening is two small triangular openings with the same area as the rhombus opening, so that the wind and water coming in from the air chamber inlet 3 Achieve even distribution across the full width. The wind coming in from the air chamber inlet 3 is provided by the bellows 9 . In addition, the ascending channel 5 on both sides of the...

Abstract

The invention discloses an air and water uniform configuration structure for a jigging coal washer of an undersize air chamber. The air and water uniform configuration structure comprises at least onepartition plate, wherein the air chamber is divided into two or three sections of compartments with equal length by the partition plates according to the width of a machine groove, and an inlet of the air chamber is connected with the compartments by a flow dividing channel formed by welding the partition plates and two edges of the air chamber; and meanwhile, the inlet of the air chamber is divided into two or three parts of openings with equal area according to the width of the machine groove of the coal washer, so that air and water entering from the inlet of the air chamber are uniformlydistributed in full width. According to the air and water uniform configuration structure provided by the invention, the separation precision is obviously improved, and gangue and middling coal are obviously reduced relatively intuitively; the clean coal content of the gangue is not more than 1%, and the clean coal content of the middling coal is reduced to 5% or below from original 10-20% or more; and the separation precision and the resource recycling rate are improved, so that the economic benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of coal washing equipment, and in particular relates to a feng shui uniform configuration structure for a jigging coal washing machine in an under-screen air chamber. Background technique [0002] Jig coal washing is a production process in the coal preparation industry. This process system is simple and reliable, with low production cost and strong adaptability to coal quality. It has been the most widely used coal preparation method in my country. The under-screen air chamber coal washer is the most commonly used model at present. However, the separation accuracy is not as high as dense medium coal washing, which affects the development of jigging coal washing. [0003] The jig sorting accuracy is not high, because the wind and water of the jig are not uniform, and the wave height of the pulsating water flow is not uniform. From the horizontal view of the machine slot, the wind and water enter the air c...
