Description

Technical Field

[0001] The present invention relates to the technical field of argillaceous sandstone treatment, and particularly to an argillaceous sandstone adding device for mine area soil improvement. Background Art

[0002] Argillaceous sandstone is a loose rock formation, specifically referring to the rock interbeds composed of thick sandstone, sandy shale and muddy sandstone in the Permian (about 250 million years ago) of the Paleozoic era and the Triassic, Jurassic and Cretaceous of the Mesozoic era. Argillaceous sandstone is a continental clastic rock series. Due to the small thickness of the overlying rock layer and low pressure, its diagenetic degree is low, the cementation degree between sand grains is poor, and the structural strength is low.

[0003] After being mixed with sand grains, the cementation property of argillaceous sandstone can fix loose sand grains, form a stable soil structure, and improve the water and fertilizer retention capacity, which can be applied to soil improvement. Due to the loose structure of argillaceous sandstone, when encountering a large amount of water, the structure of argillaceous sandstone may change and form a mud-like state. After the argillaceous sandstone is mined, there may be moisture such as rainwater on the surface of large pieces of argillaceous sandstone. Before adding the argillaceous sandstone into the sand grains, if the water content of the argillaceous sandstone is high, the pulverized argillaceous sandstone will become sticky, affecting the mixing result with the sand grains. Summary of the Invention

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] An arsenic sandstone adding device for mine soil improvement disclosed by the present invention is mainly applied to the scenario of arsenic sandstone treatment.

[0022] Referring to Figures 1 - 5 , an arsenic sandstone adding device for mine soil improvement includes a main box body 4. The inner wall of the top end of the main box body 4 is fixedly connected with a feeding hopper 3. The inner wall of the bottom end of the feeding hopper 3 is connected with a drying mechanism 7 through a linkage mechanism 5. A dust suction mechanism 6 is arranged on the drying mechanism 7. The bottom end of the drying mechanism 7 is connected with a crushing mechanism 8. The bottom end of the main box body 4 is fixedly communicated with a spiral conveying channel 1. The inner wall of one side of the main box body 4 is fixedly connected with an electric heater 2, and the electric heater 2 is located on one side of the drying mechanism 7. The top end of the feeding hopper 3 is connected with an external conveyor; The drying mechanism 7 includes a rotating cylinder 703, and a plurality of third through grooves are equidistantly penetrated through the inner circumferential wall of the rotating cylinder 703. A first filter screen 706 is fixedly connected in each third through groove. One side of the rotating cylinder 703 is penetrated with a first through groove 704, and the first through groove 704 is arranged between two of the third through grooves. Both ends of the rotating cylinder 703 are fixedly connected with second support shafts, and the second support shafts are rotatably connected to the inner wall of the main box body 4. One end of one of the second support shafts is fixedly connected with a first motor 707 through a coupling. Two fourth support plates 708 are symmetrically and fixedly connected to the outer wall of one side of the rotating cylinder 703, and a spring 709 is fixedly connected to the outer wall of the same side of each fourth support plate 708. The other end of the spring 709 is fixedly connected with a sealing plate 702. A plurality of convex rods 710 are equidistantly and fixedly connected to the inner circumferential wall of the rotating cylinder 703; There are two sets of linkage mechanisms 5. One set of the linkage mechanisms 5 is fixedly communicated with the bottom end of the feeding funnel 3, and the other set of the linkage mechanisms 5 is symmetrically arranged at the bottom end of the drying mechanism 7. Each set of the linkage mechanisms 5 respectively includes an inner frame 501, and an outer frame 505 is movably attached to the outer circumference of the inner frame 501. An electric telescopic rod 503 is fixedly connected to the outer walls of the same side of the inner frame 501 and the outer frame 505. The opposite outer walls of the two outer frames 505 are respectively attached to the outer wall of the rotating cylinder 703. The arsenic sandstone is intermittently conveyed into the feeding funnel 3 by an external conveyor. At this time, the outer frame 505 and the inner frame 501 in the upper linkage mechanism 5 are in a stretched state, and one side of the outer frame 505 just fits against one side of the rotating cylinder 703. The spring 709 is compressed, driving the sealing plate 702 to move to one side of the first through groove 704, and the arsenic sandstone can enter the rotating cylinder 703 through the first through groove 704. Then, the electric telescopic rod 503 retracts to drive the outer frame 505 to move outside the inner frame 501. Under the rebounding action of the spring 709, the sealing plate 702 blocks the first through groove 704 to complete the sealing. Driven by the first motor 707, the rotating cylinder 703 can be driven to rotate repeatedly, driving the internal arsenic sandstone to shake. By heating the external environment of the drying mechanism 7 in the main box body 4 by the electric heater 2, the complete drying of the external moisture of the arsenic sandstone can be realized, and at the same time, the arsenic sandstone can be fragmented in one round by shaking. During the shaking process, the arsenic sandstone collides with a plurality of convex rods 710, optimizing the fragmentation effect in one round, thereby ensuring the subsequent crushing effect. Similarly, driven by the electric telescopic rod 503 in the lower linkage mechanism 5, the outer frame 505 can be driven to fit against the outside of the rotating cylinder 703 to open the sealing plate 702, so that the arsenic sandstone can fall smoothly into the crushing mechanism 8.

[0023] Refer to Figure 5, in a preferred embodiment, an arc-shaped bracket 701 is movably sleeved on the outer periphery of each support plate 708, and one end of the two arc-shaped brackets 701 is fixedly connected to the sealing plate 702 at the same time. The sealing plate 702 covers the outer periphery of the first through groove 704. Two limiting blocks 705 are symmetrically and fixedly connected to the outer wall of one side of the rotating cylinder 703, and one side of the sealing plate 702 is movably attached to one side of the limiting block 705.

[0024] Refer to Figure 4 , in a preferred embodiment, a first support plate 502 is fixedly connected to the outer wall of one side of the inner frame 501, and a second support plate 504 is fixedly connected to the outer wall of the same side of the outer frame 505. The two ends of the electric telescopic rod 503 are respectively fixedly connected to the first support plate 502 and the second support plate 504.

[0025] Refer to Figure 4 , in a preferred embodiment, a plurality of third support plates 508 are fixedly connected to the outer wall of the other side of the inner frame 501, and a plurality of limiting plates 506 are fixedly connected to the outer wall of the same side of the outer frame 505. A limiting insertion rod 507 is fixedly connected to one side of each third support plate 508, and the limiting insertion rod 507 is correspondingly movably inserted into the plurality of limiting plates 506.

[0026] Refer to Figure 3 , in a preferred embodiment, the dust collection mechanism 6 includes a partition plate 603 fixedly connected to the inner wall of the main box body 4, and a third through groove and two fourth through grooves are penetrated through the partition plate 603. The upper inner frame 501 is fixedly communicated with the feeding funnel 3, and the lower inner frame 501 is fixedly communicated with the third through groove.

[0027] Refer to Figure 3 , in a preferred embodiment, an arc-shaped dust suction pipe 601 is fixedly penetrated through the top of each fourth through groove, and a plurality of dust suction ports 605 are penetrated through the inner side of the arc-shaped dust suction pipe 601. A negative pressure dust collector 602 is fixedly connected to the middle section of each arc-shaped dust suction pipe 601. A plurality of inclined baffles 604 are fixedly connected to the inner wall of the main box body 4, and the inclined baffles 604 are distributed at the bottom of the two fourth through grooves. Since there will be arsenic sandstone powder in the arsenic sandstone, when rotating and drying, the powder will pass through the first filter screen 706 and enter the main box body 4. At this time, through the arc-shaped dust suction pipes 601 arranged on both sides, under the action of the negative pressure dust collector 602, the leaked powder can be sucked through the dust suction ports 605, and the powder is conveyed to the bottom of the partition plate 603, so that the powder can enter the crushing mechanism 8 along the trend and be mixed with the crushed arsenic sandstone, avoiding the waste of arsenic sandstone powder and the influence of powder accumulation on the drying effect. In addition, through the arrangement of the plurality of inclined baffles 604, when the powder falls, it can avoid a large amount of dust raising of the falling powder under the influence of air flow, which affects the normal use of the negative pressure dust collector 602.

[0028] Refer toFigure 6 In a preferred embodiment, the crushing mechanism 8 includes two crushing rollers 804, and a third support shaft is fixedly connected to both ends of each crushing roller 804. The third support shaft is rotatably connected to the inner wall of the main box body 4, and a gear 813 is fixedly connected to the same end of the two third support shafts. The two gears 813 are meshed with each other, and a second motor 803 is fixedly connected to the other end of one of the third support shafts.

[0029] Refer to Figure 6 In a preferred embodiment, a transition funnel 805 is fixedly connected to the inner wall of the main box body 4, and the transition funnel 805 is located at the bottom end of the crushing roller 804. A first support shaft 810 is rotatably connected to the inner walls of the opposite sides of the main box body 4, and a sector-shaped hollow support frame 801 is fixedly connected to the two first support shafts 810 at the same time. One end of the first support shaft 810 is fixedly connected to a third motor 806 through a coupling.

[0030] Refer to Figure 6 In a preferred embodiment, a second through groove 808 is provided through the inner wall of one side of the sector-shaped hollow support frame 801, and a second filter screen 811 is fixedly connected to the opening of the sector-shaped hollow support frame 801. A discharge port 809 is provided through the inner wall of the bottom end of the main box body 4, and a guiding support 807 is fixedly connected to the bottom end of the discharge port 809. An inclined support 812 and a turnover bin 802 are fixedly connected to the inner wall of the bottom end of the main box body 4, and the turnover bin 802 is arranged on one side of the inclined support 812. When the dried arsenic sandstone falls between the two crushing rollers 804 through the third through groove, the driving of the second motor 803 and the meshing structure of the two gears 813 can drive the two crushing rollers 804 to rotate synchronously inward to crush the arsenic sandstone. The crushed arsenic sandstone falls onto the upper part of the second filter screen 811 arranged in a V shape through the transition funnel 805. The arsenic sandstone is driven by the third motor 806 to shake through the sector-shaped hollow support frame 801 to provide the filtering effect of the arsenic sandstone and accelerate the filtering effect. The filtered arsenic sandstone falls through the second through groove 808 and the discharge port 809 and is conveyed and added through the spiral conveying channel 1. After filtering for a period of time, the third motor 806 drives the sector-shaped hollow support frame 801 to rotate to one side and stop. One side of the second filter screen 811 forms an inclined surface with the inclined support 812 to form the whole inclined surface, so that the large-particle arsenic sandstone remaining on the second filter screen 811 slides down along the inclined surface and is temporarily stored in the turnover bin 802, which can ensure the sustainable use of the second filter screen 811.

[0031] Working principle: The arid sandy rock is intermittently conveyed to the feeding hopper 3 by an external conveyor. At this time, the outer frame 505 and the inner frame 501 in the linkage mechanism 5 above are in a stretched state. One side of the outer frame 505 just fits against one side of the rotary drum 703, and the spring 709 is compressed, driving the sealing plate 702 to move to one side of the through slot 704. The arid sandy rock can enter the rotary drum 703 through the through slot 704. Then, the outer frame 505 is driven by the retraction of the electric telescopic rod 503 to move outside the inner frame 501. Under the action of the spring 709 rebounding, the sealing plate 702 blocks the through slot 704 to complete the sealing. Driven by the motor 707, the rotary drum 703 can rotate repeatedly, driving the arid sandy rock inside to shake. By heating the external environment of the drying mechanism 7 in the main box body 4 with the electric heater 2, the complete drying of the external moisture of the arid sandy rock can be achieved. At the same time, the arid sandy rock can also be crushed once by shaking. During the shaking process, the arid sandy rock collides with multiple convex rods 710 to optimize the crushing effect of the first round, thus ensuring the subsequent crushing effect. Similarly, driven by the electric telescopic rod 503 in the linkage mechanism 5 below, the outer frame 505 can be driven to fit on the outside of the rotary drum 703 to open the sealing plate 702, so that the arid sandy rock can fall smoothly into the crushing mechanism 8.
