Description

Technical Field

[0001] The invention relates to the technical field of coal gangue crushing, in particular to a coal gangue raw material sorting, crushing and processing device. Background Art

[0002] Coal gangue raw materials are solid waste discharged during the coal mining and coal washing processes. It is a black-gray rock with a low carbon content and harder than coal that accompanies the coal seam during the coal formation process. It includes excavation gangue during tunnel excavation, gangue mined from the roof, floor and interlayer during mining, and washed gangue picked out during coal washing.

[0003] Coal gangue can be used as building materials (such as bricks, concrete), soil conditioner, fuel (low calorific value fuel), etc., and has the potential for reuse. In the process of recycling coal gangue, it is necessary to sort out the broken coal mixed in the coal gangue raw materials, and then crush the relatively clean coal gangue to facilitate subsequent use.

[0004] However, there is often moisture mixed in the gangue raw materials (for example, humid weather or poor storage conditions can cause the gangue raw materials to become damp, or they come into contact with moisture during coal mining or coal washing), which will cause the crushed coal to adhere to the gangue, making it difficult to completely separate the crushed coal from the gangue raw materials. In addition, when the gangue is finally crushed, the crushed fine particles will also be mixed with coal components, affecting the purity of the final product, thereby affecting the quality of the final product.

[0028] The elastic support mechanism includes four support rods 12, and the four support rods 12 are fixedly connected to the upper ends of the two base frames 13 in pairs.

Since the rectangular shell 9 is connected with four guide posts 10 and all are inserted into the corresponding support rods 12, and springs 15 are connected between the rectangular shell 9 and the four support rods 12, the rectangular shell 9 can only be continuously shaken in the left and right directions, and the guide posts 10 will slide left and right in the support rods 12.

The inner top end surface of the rectangular shell 9 and the upper end surface of the orifice plate 20 are respectively fitted with the upper and lower ends of the two groups of material blocking shells 32. The two groups of material blocking shells 32 are staggered and symmetrically arranged, and a plurality of strip grooves 33 are opened on the outer walls of the two groups of material blocking shells 32.

[0031] The jacking mechanism includes four V-shaped blocks 29 and four connecting plates 16 arranged below the orifice plate 20.

[0032] The drying mechanism includes two hot air blowers 4 and a plurality of square tubes 7, the two hot air blowers 4 are fixedly mounted on the upper end of the shell 3, the air outlet ends of the two hot air blowers 4 are connected with a Z-shaped tube 5, the ends of the two Z-shaped tubes 5 away from the hot air blowers 4 are connected with a connecting tube 18, the outer walls of the two connecting tubes 18 are respectively connected with a group of hoses 14 between the two side walls of the rectangular shell 9, the two groups of hoses 14 correspond to the positions of the two groups of material retaining shells 32, and the ends of the two groups of hoses 14 away from the connecting tube 18 are respectively connected with the ends of the two groups of material retaining shells 32, the tops of the outer walls of the two connecting tubes 18 are connected with vertical tubes 22, the tops of the two vertical tubes 22 are connected with a splicing tube 6, a plurality of square tubes 7 are linearly arrayed and fixedly connected to the upper end of the rectangular shell 9 near the middle, and the middle of the inner walls of the plurality of square tubes 7 are fixedly connected with a partition 30 (such as Figure 5 As shown in FIG. 1 ), the lower ends of the plurality of square tubes 7 and the upper ends of the rectangular shells 9 are provided with a plurality of slots 31 (as shown in FIG. Figure 5 As shown in the figure, both ends of the plurality of square tubes 7 are connected to the outer walls of the two spliced ​​tubes 6 by fixed tubes 23.

[0033] The driving mechanism includes a splicing plate 11, which is fixedly connected between two corresponding front and rear support rods 12. A motor 17 is fixedly installed on the side wall of the splicing plate 11. The output shaft end of the motor 17 is fixedly connected to a rotating column 36, and a push plate 37 is fixedly connected to the outer wall of the rotating column 36.

[0034] Specifically, the motor 17 can be started to drive the rotating column 36 and the push plate 37 to rotate together. It should be noted that the rotating column 36 is located directly below one of the V-shaped blocks 29, and each time the push plate 37 rotates one circle, it will push one of the V-shaped blocks 29 upward once, and the V-shaped block 29 can drive the connected square plate 19 to squeeze the spring 28, so when the push plate 37 rotates away from the lower end of the V-shaped block 29, under the action of the spring 28, the V-shaped block 29 will return to move downward, and as the push plate 37 continues to rotate, the V-shaped block 29 can keep intermittently moving up and down.

[0035] The outer wall of the rectangular shell 9 is fixedly sleeved with a sealing frame 2 , and the front end of the sealing frame 2 is in contact with the rear end of the shell 3 .

[0036] Specifically, by providing the sealing frame 2, when the rectangular shell 9 shakes left and right, the sealing frame 2 can be fitted on the rear end of the shell 3 and slide left and right, thereby sealing the gap between the rectangular shell 9 and the shell 3 to prevent dust from escaping from the gap.

[0037] In this embodiment, first, the coal gangue raw materials containing water can be continuously and slowly conveyed to the feed hopper 8 through the existing conveying device, and the coal gangue raw materials will fall into the rectangular shell 9 and be on the orifice plate 20. Since the upper end surface of the orifice plate 20 is inclined, the coal gangue raw materials will roll along its inclined surface toward the shell 3. During this period, through the cooperation between the vibration motor 21 and the elastic support mechanism, the rectangular shell 9 can be driven to shake left and right continuously, and the coal gangue raw materials will also shake accordingly, so that the broken coal mixed in the raw materials or the broken coal adhering to the surface of the coal gangue can be continuously shaken off along the pores of the orifice plate 20. It should be noted that a dust bag or dust collecting bag can be installed at the bottom of the rectangular shell 9 to seal the space below the orifice plate 20 to facilitate the collection of broken coal.

[0038] When the gangue material rolls down on the orifice plate 20, it will also pass through the two sets of material blocking shells 32. Since the two sets of material blocking shells 32 are staggered and symmetrically arranged, combined with Figure 6 From the perspective of the rolling direction of the coal gangue raw material, the rolling direction of the coal gangue raw material will be tortuous, thereby extending the time for the coal gangue raw material to roll on the perforated plate 20, and can more fully shake off the broken coal mixed in the raw material and the broken coal adhering to the surface of the coal gangue. At the same time, start the two hot air blowers 4, each of which will transport the hot air through the Z-shaped tube 5, the connecting tube 18 and a group of hoses 14 to a corresponding group of material retaining shells 32, and the hot air will finally be blown out laterally along the multiple strip grooves 33 opened on the outer walls of the two groups of material retaining shells 32. It should be noted that the inner wall of the strip groove 33 is installed with a breathable filter to prevent the broken coal from entering the material retaining shell 32. Thereby, hot air can be evenly blown to the tortuous rolling sections of the coal gangue raw materials. The hot air blown out in this form can fully dry the moisture mixed in the coal gangue raw materials, and can also dry the wet and broken coal adhering to the outer surface of the coal gangue, so that the broken coal adhering to the outer surface of the coal gangue can be easily shaken off.

[0039] At the same time, through the cooperation between the driving mechanism and the spring 28, a V-shaped block 29 can be driven to move up and down intermittently. Since the frame 34 is connected between the four V-shaped blocks 29, the four V-shaped blocks 29 will move up and down intermittently synchronously. Each V-shaped block 29 will drive a group of top columns 35 to slide up and down intermittently in the pores of the orifice plate 20, and combined with Figure 6 and Figure 7 From the perspective of the four groups of top pillars 35, which correspond to the tortuous rolling sections of the coal gangue raw materials, when the four groups of top pillars 35 move upward, they will not only extend out of the upper end of the orifice plate 20, but also push the coal gangue raw materials in the tortuous rolling sections, causing the coal gangue to roll and flip over to a certain extent and further improve the dynamic effect, thereby further shaking off the broken coal adhering to the surface of the coal gangue.

[0040] Finally, the clean coal gangue will fall into the interior of the crusher 1 along the shell 3, and the crusher 1 can crush the coal gangue and finally discharge the coal gangue in the form of fine particles. The staff can collect it with a collecting tool under the crusher 1.

[0041] To sum up, before the gangue raw material enters the crusher 1 in a rolling manner, it will not only be shaken left and right, but also the rolling path will be tortuous, and multiple lateral blowing will be applied to the tortuous section, and the gangue in the tortuous section will be pushed and turned over, so that the moisture in the gangue raw material can be well removed, and the wet crushed coal adhering to the surface of the gangue can be dried to make it easy to be shaken off, thereby increasing the sorting amount of crushed coal, and finally when the gangue is crushed, the mixed coal component in the crushed fine particles is greatly reduced, thereby improving the purity and quality of the final product.

[0042] It is worth mentioning that when the rectangular housing 9 shakes left and right, it will also drive the two sets of hoses 14 to move together, and the hoses 14 are soft, so the hoses 14 will bend or tend to straighten without breaking or being damaged. The hoses 14 are connected to the connecting pipes 18, and the connecting pipes 18 will not be subjected to tension.

[0043] Example 2: Please refer to Figure 3 , Figure 6 and Figure 7 This embodiment further explains the first embodiment. Concave rods 24 are provided above the two groups of hoses 14. The two concave rods 24 are respectively fixedly connected to the two side walls of the rectangular shell 9. The upper ends of the eight connecting rods 27 are fixedly connected to connecting columns 26. Among them, the upper ends of four front and rear corresponding connecting columns 26 and the other four front and rear corresponding connecting columns 26 are fixedly connected to pressure rods 25. The two pressure rods 25 are respectively located below the two groups of hoses 14.

[0044] In this embodiment, when the four V-shaped blocks 29 are driven to move upward, each V-shaped block 29 will drive the two square plates 19 to move upward, each square plate 19 will squeeze the spring 28 connected to the corresponding connecting plate 16, and each square plate 19 will drive the connecting rod 27 connected to it to slide upward in the corresponding connecting plate 16. At this time, the pressure rods 25 connected to the upper ends of the four front and rear corresponding connecting columns 26 and the pressure rods 25 connected to the upper ends of the other four front and rear corresponding connecting columns 26 will move upward, and the two pressure rods 25 will squeeze the two groups of hoses 14 and press the two groups of hoses 14 under the corresponding concave rods 24, so that the two groups of hoses 14 are deformed and closed, then at this time, the two connecting pipes 18 are entered. The hot air inside can only enter along the vertical pipes 22 on the two connecting pipes 18. Both vertical pipes 22 are provided with one-way valves, and the one-way valves inside the two vertical pipes 22 will be opened under the action of air pressure, and then the hot air will enter the two spliced ​​pipes 6, and then the hot air will enter the multiple square tubes 7 along the fixed pipes 23 on the two spliced ​​pipes 6, and finally blow vertically to the coal gangue raw materials in the tortuous section through the multiple square tubes 7 and the hole grooves 31 opened at the upper ends of the rectangular shells 9. The vertical hot air can further improve the uniformity of drying the coal gangue raw materials, and can blow away the broken coal in the coal gangue raw materials and the broken coal adhered to the outer surface of the coal gangue more quickly along the pores of the orifice plate 20, thereby improving the sorting speed of the broken coal.

[0045] When the four V-shaped blocks 29 move downward and reset due to the action of the spring 2 28, the two pressure rods 25 will loosen the two sets of hoses 14, so that the two sets of hoses 14 are opened, and the hot air will enter the two sets of material retaining shells 32 along the two sets of hoses 14, and be blown out laterally along the multiple strip grooves 33 opened outside the two sets of material retaining shells 32. At this time, the one-way valves inside the two vertical pipes 22 will continue to close to seal the two vertical pipes 22. By analogy, the coal gangue raw materials in the zigzag section will be intermittently blown horizontally and vertically.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
