Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the viscosity of the coal particles in the prior art, the fine particles are easier to attach to the larger particles to make the coal stick into agglomerates, and the sieve screen in the prior art Single, resulting in some coal particles smaller than the size of the sieve cannot pass through the sieve, which affects the screening accuracy and efficiency, and a screening equipment for coal mining and its use method are proposed

Embodiment 1

[0044] refer to Figure 1-3 , Figure 5 , Image 6 , Figure 9 , Figure 10 , a screening device for coal mining, comprising a base 1, a front beam 2, a rear beam 3, the front beam 2 is higher than the rear beam 3, and the front beam 2 and the rear beam 3 are respectively fixed on the top of the base 1, the front beam 2 and the top of the rear crossbeam 3 are fixed with a supporting shaking mechanism 4, the front crossbeam 2 and the rear crossbeam 3 are connected with a sieve housing 5 through the supporting shaking mechanism 4, and there is a fixed set between the front crossbeam 2 and the rear crossbeam 3 The feed bin 6 at the bottom of the sieving housing 5, the top of the sieving housing 5 is provided with a feed inlet 7, the bottom of the sieving housing 5 is provided with a mounting hole 8, and a fixed screen 9 is fixed in the mounting hole 8, The bottom end of the screen moving housing 5 is also provided with a moving screen 10 placed above the fixed screen 9, and t...

Embodiment 2

[0050] refer to Figure 4 , Figure 7 , Figure 8 , Figure 11 , Figure 12 , is basically the same as Embodiment 1, furthermore, the follow-up mechanism 12 includes an extension shaft 12-1, a follow-up rod 12-2, a rotating column 12-3, and the extension shaft 12-1 is fixed on the bottom of the moving screen 10 side wall, and the end of the extension shaft 12-1 away from the moving screen 10 runs through the sieve housing 5 and is connected in rotation with the follower rod 12-2, and the end of the follower rod 12-2 away from the extension shaft 12-1 is inserted into the rotating column On 12-3, the rotating column 12-3 is rotated and arranged on the side wall of the feed bin 6, and the moving screen 10 pulls the follower rod 12-2 through the extension shaft 12-1 when reciprocating, because the follower rod 12- 2 is installed on the side wall of the material bin 6 through the rotation of the rotating column 12-3, so the swing of the follower rod 12-2 can be realized under ...

Abstract

The invention discloses a screening device for coal mining and an application method thereof, belonging to the technical field of coal mining screening. A screening device for coal mining, comprising a base, a front beam, and a rear beam, the front beam is higher than the rear beam, and the front beam and the rear beam are respectively fixed on the top of the base, and the tops of the front beam and the rear beam are Both of them are fixed with a supporting shaking mechanism, and the front beam and the rear beam are connected with a sieving shell through the supporting shaking mechanism; the present invention uses a power mechanism to drive the moving screen to reciprocate to screen the coal, and the moving screen is moving At the same time, the traction link will be driven by the follow-up mechanism, so that the sieve shell will be shaken by the traction link, and then the coal falling on the fixed screen will be further screened. The invention utilizes the synchronization of the moving screen and the fixed screen Shaking can realize sufficient sieving of coal particles, so as to overcome the problems of coal particles sticking into agglomerates and low screening accuracy and efficiency in the prior art.

Description

technical field [0001] The invention relates to the technical field of coal mining screening, in particular to a screening device for coal mining and a method for using the same. Background technique [0002] In the process of coal mining, due to the different burial depths of coal resources, mine mining (deep burial) and open-pit mining (shallow burial) are generally used accordingly. It has been one of the main energy sources used by the human world for centuries. Coal is still one of the indispensable energy sources for the production and life of human society at present and for a long time to come. Existing coal needs to be screened after being mined. [0003] Traditional coal screening mainly screens coal through the vibrating screen inside the machine. For example, the patent application number is 201611255020.9, the application publication number is CN106824770A, and the name is powdered coal screening device. The disclosed technical solution drives the screen by sett...
