Description

Technical Field

[0001] The utility model belongs to the technical field of coal block processing, and particularly relates to a multi-stage coal block processing assembly. Background Technique

[0002] Coal is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. The sum of carbon, hydrogen, and oxygen accounts for more than 95% of the organic matter. It is a very important energy source and also an important raw material for the metallurgical and chemical industries. There are several classifications such as lignite, bituminous coal, anthracite, and semi-anthracite. The famous writer Zhu Ziqing also wrote a poem titled "Coal", endowing it with a unique symbolic meaning.

[0003] When coal blocks are freshly mined, they are often stacked together after being mixed with coal blocks of different sizes and coal cinder. If coal blocks of different sizes are directly packed and sold without screening, the highest economic benefits cannot be obtained, and some coal blocks with larger volume, more complete block shape, and higher economic benefits are wasted. Moreover, coal blocks and coal cinder can be utilized in different industries. If they are stacked and packed together, screening is still required when coal blocks or coal cinder are needed separately later. For this reason, we propose a multi-stage coal block processing assembly to solve the above-mentioned problems. Content of the Utility Model

[0021] Please refer to Figures 1 - 5 , the present invention provides a multi-stage coal block processing assembly, including a support frame 1, a primary screening assembly 2 and a secondary screening assembly 3, characterized in that: the primary screening assembly 2 is installed on the support frame 1, and the secondary screening assembly 3 is arranged at the discharge end of the primary screening assembly 2 for separating coal blocks and cinders. A cinder collection box 4 and a small coal block collection box 5 are arranged at the bottom of the secondary screening assembly 3. The cinder collection box 4 is located directly below the secondary screening assembly 3, and the small coal block collection box 5 is located at the discharge end of the secondary screening assembly 3.

[0022] In this embodiment, the primary screening assembly 2 includes a driving motor 21 and a driven wheel 23. The driving motor 21 is installed on the support frame 1. The output shaft of the driving motor 21 is fixedly connected with a driving wheel 22. A transmission belt 24 is arranged between the driving wheel 22 and the driven wheel 23, and the driving wheel 22 and the driven wheel 23 are connected by the transmission belt 24 for transmission. An eccentric rod 25 is rotatably connected to the driven wheel 23. One end of the eccentric rod 25 away from the driven wheel 23 is hinged to a linking rod 26. One end of the linking rod 26 away from the eccentric rod 25 is hinged to a sliding frame 27. A screen plate 28 is engaged in the sliding frame 27.

[0023] In this embodiment, four support bases 11 are installed on the top of the support frame 1, and pulleys 12 are rotatably connected to the four support bases 11. The bottom of the sliding frame 27 is in contact with the tops of the four pulleys 12.

[0024] In this embodiment, the secondary screening assembly 3 includes a positioning plate 31. Two limiting chutes 32 are formed at the top of the positioning plate 31. Two sliders 35 are slidably connected to the inside of each limiting chute 32. An auxiliary support plate 36 is mounted on each slider 35. A plurality of auxiliary support plates 36 are all in contact with the top of the positioning plate 31. Two side baffles 33 are arranged above the positioning plate 31. A screen grid 34 is connected to the opposite side of each of the two side baffles 33.

[0025] Among them, both of the two side baffles 33 are L-shaped.

[0026] In this embodiment, the two screen grids 34 are both arranged in an upper and lower stacked manner, and the widths of the two screen grids 34 are both greater than half of the width of the positioning plate 31.

[0027] In this embodiment, a plurality of threaded rods 37 are threadedly connected to the sliders 35, and the tops of the plurality of threaded rods 37 are fixedly connected with pressing gaskets 38.

[0028] In this embodiment, the inclination angle between the secondary screening assembly 3 and the horizontal plane is 30 degrees to 60 degrees.

[0029] The working principle and usage process of the present utility model: When the device is working, first clean the screen plate 28, then place the screen plate 28 into the sliding frame 27. According to the requirements of this batch, slide the two side baffles 33 to drive the two screen grids 34 to slide. When the volume of the small coal blocks in the small coal block collection box 5 needs to be smaller for this batch, move the two side baffles 33 so that the pores formed after the two screen grids 34 are staggered and overlapped are smaller. And during the movement, the sliders 35 and the auxiliary support plates 36 cooperate to slide in the limiting chutes 32 on the positioning plate 31. After the adjustment is completed, rotate the plurality of threaded rods 37 to make the plurality of threaded rods 37 drive the pressing gaskets 38 to rise and press against the bottom of the positioning plate 31, while the auxiliary support plates 36 cooperate to press against the top of the positioning plate 31, that is, the auxiliary support plates 36 and the plurality of pressing gaskets 38 form a clamping and fixing effect. Subsequently, place the coal cinder collection box 4 and the small coal block collection box 5 at the corresponding positions.

[0030] Pour the collected coal blocks onto the screen plate 28, start the drive motor 21. The drive motor 21 drives the transmission belt 24 to rotate through the driving wheel 22, that is, drives the eccentric rod 25 to rotate through the driven wheel 23. When the eccentric rod 25 rotates, it will drive the sliding frame 27 to reciprocate and shake in the direction of approaching / away from the eccentric rod 25 through the linkage rod 26. Cooperating with the screen plate 28 can form a shaking and screening effect. And there is a support base 11 provided to support the rotation of the pulley 12, which can make the movement of the sliding frame 27 smoother. Subsequently, the coal cinder and small coal blocks screened by the sliding frame 27 pass through the secondary screening assembly 3 and are filtered by the secondary screening formed by the two screen frames 34. The small coal blocks will be introduced into the small coal block collection box 5 through the secondary screening assembly 3. Finally, collect the large coal blocks on the sliding frame 27, the coal cinder in the coal cinder collection box 4 and the small coal blocks in the small coal block collection box 5.
