[0001] The invention relates to the field of sintered coal gangue porous brick processing, in particular to a multi-layer screening device for sintered coal gangue porous brick processing. Background Art
[0002] Sintered coal gangue porous brick is a building material made of coal gangue as the main raw material through a roasting process. It has a porous structure and is mainly used in the load-bearing parts of buildings. The use of sintered coal gangue porous bricks can reduce the consumption of land resources, reduce energy consumption, and utilize industrial waste, which has significant environmental benefits.
[0003] Since the main raw materials of sintered gangue porous bricks include gangue, clay, shale and fly ash, etc., and these raw materials contain a large amount of light debris, such as wood chips, plastic sheets and paper, etc., these light debris are easy to adhere to the screen during the screening process, causing the screen to be blocked. This not only reduces the screening efficiency, but also may damage the screen, increasing the maintenance frequency and cost. How to solve these problems has become a problem that needs to be solved urgently by technicians in this field. Summary of the invention
[0004] In order to make up for the above shortcomings, the present invention provides a multi-layer screening device for processing sintered coal gangue porous bricks, aiming to solve the problem that the existing multi-layer screening device cannot separate light debris in the raw materials.
[0005] The present invention is achieved in that:
[0006] The present invention provides a multi-layer screening device for processing sintered coal gangue porous bricks, comprising a bin body and a feed inlet, wherein the feed inlet is fixedly connected to the top of the bin body, and further comprising:
[0007] A crushing assembly is located below the feed inlet. The presence of the crushing assembly can crush the raw materials entering the bin through the feed inlet to ensure the normal progress of subsequent screening work.
[0008] The material separation component is located on the surface of the bin body. The existence of the material separation component can separate a large amount of light debris generated during the crushing process from the crushed raw materials, thereby preventing a large amount of light debris from clogging the screening holes of the subsequent screening structure.
[0009] The screening component is located inside the bin body. The presence of the screening component can screen the raw materials after crushing, and classify and place the raw materials of different specifications to facilitate the subsequent processing of the raw materials.
[0010] Preferably, the pulverizing assembly comprises a motor, an output shaft and a pulverizing roller, the motor is fixedly connected to the outer wall of the bin body, the output shaft is installed inside the bin body, and the pulverizing roller is fixedly connected to the outer wall of the output shaft.
[0011] Preferably, an extension frame is fixedly connected to the bottom of the feed port, both ends of the output shaft pass through the inner wall of the bin body and extend to the outer wall of the bin body, and the output end of the motor is connected to one end of the output shaft extending to the outer wall of the bin body.
[0012] By adopting the above technical solution, the existence of the extension frame can effectively prevent the raw materials from splashing when the crushing roller is crushing the raw materials, resulting in the crushing roller being unable to crush the raw materials well. After the motor is started, the crushing roller can be driven to rotate through the output shaft, thereby crushing the raw materials put into the bin body.
[0013] Preferably, the material distribution assembly includes a frame, a transmission member, a bracket, fan blades, a hollow plate 1, a sliding frame, a stacking bin and a hollow plate 2, the frame is fixedly connected to the inner wall of the bin body, the transmission member is installed on the output shaft and extends to one end of the outer wall of the bin body, the bracket is fixedly connected to the inside of the frame, the fan blades are located inside the frame, the hollow plate 1 is fixedly connected to the inside of the frame, the sliding frame is fixedly connected to the outer wall of the bin body, the stacking bin is installed inside the sliding frame, and the hollow plate 2 is located on the outer wall of the stacking bin.
[0014] Preferably, the output shaft is connected to the driving wheel of the transmission member, the diameter of the driving wheel of the transmission member is larger than the diameter of the driven wheel, the outer wall of the fan blade is fixedly connected with a connecting shaft, the driven wheel of the transmission member is connected to the connecting shaft, and the connecting shaft arranged on the outer wall of the fan blade passes through the bracket and is rotatably connected to the bracket.
[0015] By adopting the above technical solution, when the output shaft rotates, the fan blades can be driven to rotate through the transmission member. Since the diameter of the driving wheel of the transmission member is larger than the diameter of the driven wheel, when the output shaft rotates, the rotation speed of the fan blades will be accelerated, thereby accelerating the speed at which air enters the interior of the warehouse body. The existence of the bracket can support the fan blades through the connecting shaft.
[0016] Preferably, a slide rail is provided on the top of the slide frame, a card slot is provided on the bottom of the slide frame, the outer wall of the stacking bin is slidably connected to the inner wall of the slide frame, a card block is fixedly connected to the bottom of the hollow plate 2, the hollow plate 2 is slidably connected to the slide rail, and the card block located at the bottom of the hollow plate 2 is engaged with the card slot.
[0017] By adopting the above technical scheme, the stacking bin can be taken out from the inside of the slide frame by sliding, which makes it convenient for the operator to centrally process the light debris collected in the stacking bin, and the disassembly and assembly of the hollow plate 2 can be completed by sliding. The existence of the hollow plate 2 can block the light debris without affecting the air circulation, thereby preventing the light debris from overflowing from the stacking bin and causing the debris to scatter. At the same time, by setting the card block, the card slot and the slide rail, the restriction of the hollow plate 2 can be well completed, ensuring the fitting effect between the hollow plate 2 and the stacking bin.
[0018] Preferably, the screening assembly includes a multi-layer screening bin, a bent rod, a cam, a limit plate, a spring push rod and a guide plate, the multi-layer screening bin is located inside the bin body, the bent rod is fixedly connected to the top of the multi-layer screening bin, the cam is fixedly connected to the outer wall of the output shaft, the limit plate is fixedly connected to the inner wall of the bin body, the spring push rod is fixedly connected to the bottom of the inner wall of the bin body, and the guide plate is fixedly connected to the outer wall of the bin body.
[0019] Preferably, the outer wall of the multi-layer screening bin is slidably connected to the inner wall of the bin body, and the top of the bent rod is located within the rotation diameter of the cam.
[0020] By adopting the above technical solution, when the output shaft drives the cam to rotate, the cam can be used to push the bent rod to descend, so that the bent rod drives the multi-layer screening bin to move. At this time, the multi-layer screening bin will speed up the screening efficiency of the internal raw materials.
[0021] Preferably, the bottom of the limit plate abuts against the top of the bent rod, and the top of the spring push rod is fixedly connected to the bottom of the multi-layer screening bin.
[0022] By adopting the above technical solution, after the cam is separated from the bent rod, the spring push rod pushes the multi-layer screening bin to reset, so that the bent rod contacts and collides with the limit plate, which can make the raw materials inside the multi-layer screening bin shake, avoiding the situation where the raw materials are stuck inside the screen hole and cause the screen hole to be blocked.
[0023] The beneficial effects of the present invention are:
[0024] 1. By setting transmission parts and fan blades, when the motor drives the output shaft to rotate, the output shaft will drive the fan blades to rotate through the transmission parts. At this time, the fan blades will blow the outside air into the interior of the bin body, and when the output shaft rotates, it will drive the crushing roller to rotate and crush the material. The crushed material will fall through the crushing roller. At this time, the air blown in by the fan blades will separate the light debris generated in the crushing process from the raw materials, and blow the light debris into the interior of the stacking bin, thereby solving the problem that the existing multi-layer screening device cannot separate the light debris in the raw materials.
[0025] 2. By setting up the stacking bin and the hollow plate 2, when light debris is blown into the stacking bin under the action of the fan blades, the hollow plate 2 will block the light debris, and the air entering and leaving the stacking bin will be discharged through the hollow plate 2. The setting of the stacking bin can centrally process light debris to avoid the problem of scattered light debris and inconvenient collection. At the same time, the stacking bin is installed inside the sliding frame by sliding. After completing the collection of light debris, it is convenient to take out the stacking bin and replace it, and the operation is simple and convenient.
[0026] 3. By setting a cam and a spring push rod, when the output shaft rotates, the cam will be driven to rotate. After the cam rotates to a certain angle, it will push the bent rod to move, causing the multi-layer screening bin to drop and exert pressure on the spring push rod. When the cam is separated from the bent rod, the spring push rod will push the multi-layer screening bin and the bent rod to reset until they abut against the bottom of the limit plate. The collision impact force generated when the bent rod contacts the limit plate will drive the multi-layer screening bin to shake, thereby improving the screening effect of the multi-layer screening bin on the crushed raw materials.

DETAILED DESCRIPTION
[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0038] Reference Figure 1-Figure 8 A multi-layer screening device for processing sintered coal gangue porous bricks comprises a silo body 1 and a feed inlet 2, wherein the feed inlet 2 is fixedly connected to the top of the silo body 1, and further comprises:
[0039] The crushing assembly 3 is located below the feed inlet 2. The crushing assembly 3 can crush the raw materials entering the interior of the silo 1 through the feed inlet 2 to ensure the normal performance of subsequent screening work.
[0040] The material separation component 4 is located on the surface of the bin body 1. The existence of the material separation component 4 can separate a large amount of light debris generated during the crushing process from the crushed raw materials, thereby preventing a large amount of light debris from clogging the screening holes of the subsequent screening structure.
[0041] The screening component 5 is located inside the bin body 1. The screening component 5 can perform screening operations on the raw materials after crushing, and classify and place the raw materials of different specifications, so as to facilitate the subsequent processing of the raw materials.
[0042] The crushing assembly 3 includes a motor 301 , an output shaft 302 and a crushing roller 303 . The motor 301 is fixedly connected to the outer wall of the bin body 1 , the output shaft 302 is installed inside the bin body 1 , and the crushing roller 303 is fixedly connected to the outer wall of the output shaft 302 .
[0043] It needs to be further explained that: an extension frame is fixedly connected to the bottom of the feed port 2, both ends of the output shaft 302 pass through the inner wall of the bin body 1 and extend to the outer wall of the bin body 1, and the output end of the motor 301 is connected to one end of the output shaft 302 extending to the outer wall of the bin body 1. The existence of the extension frame can effectively prevent the crushing roller 303 from splashing the raw materials when the crushing roller 303 is crushing the raw materials, resulting in the crushing roller 303 being unable to crush the raw materials well. After the motor 301 is started, the crushing roller 303 can be driven to rotate by the output shaft 302, thereby crushing the raw materials put into the bin body 1.
[0044] The raw materials are put into the interior of the bin body 1 through the feed port 2. After passing through the extension frame, the raw materials are accumulated on the top of the crushing roller 303. The operation of the motor 301 is controlled so that the motor 301 drives the output shaft 302 to rotate through the output end. When the output shaft 302 rotates, it drives the crushing roller 303 to rotate. At this time, the crushing roller 303 will crush the raw materials accumulated on the top of the crushing roller 303.
[0045] The material distribution component 4 includes a frame 401, a transmission member 402, a bracket 403, a fan blade 404, a hollow plate 1 405, a sliding frame 406, a stacking bin 407 and a hollow plate 2 408. The frame 401 is fixedly connected to the inner wall of the bin body 1, the transmission member 402 is installed on one end of the output shaft 302 extending to the outer wall of the bin body 1, the bracket 403 is fixedly connected to the inside of the frame 401, the fan blade 404 is located inside the frame 401, the hollow plate 1 405 is fixedly connected to the inside of the frame 401, the sliding frame 406 is fixedly connected to the outer wall of the bin body 1, the stacking bin 407 is installed inside the sliding frame 406, and the hollow plate 2 408 is located on the outer wall of the stacking bin 407.
[0046] It needs to be further explained that: the output shaft 302 is connected to the driving wheel of the transmission member 402, and the driving wheel diameter of the transmission member 402 is larger than the driven wheel diameter. When the output shaft 302 rotates, the fan blade 404 can be driven to rotate through the transmission member 402. Since the driving wheel diameter of the transmission member 402 is larger than the driven wheel diameter, when the output shaft 302 rotates, the rotation speed of the fan blade 404 will be accelerated, thereby accelerating the speed at which air enters the interior of the warehouse body 1. The outer wall of the fan blade 404 is fixedly connected with a connecting shaft, and the driven wheel of the transmission member 402 is connected to the connecting shaft. The connecting shaft arranged on the outer wall of the fan blade 404 passes through the bracket 403 and is rotatably connected to the bracket 403. The existence of the bracket 403 can support the fan blade 404 through the connecting shaft. A slide rail is provided on the top of the slide frame 406, and a card slot is provided on the bottom of the slide frame 406. The outer wall of 407 is slidably connected to the inner wall of the slide frame 406, and the stacking bin 407 can be taken out from the inside of the slide frame 406 by sliding, so that the operator can centrally process the light debris collected in the stacking bin 407. A card block is fixedly connected to the bottom of the hollow plate 408, and the hollow plate 408 is slidably connected to the slide rail, so the disassembly and assembly of the hollow plate 408 can be completed by sliding. The existence of the hollow plate 408 can block light debris without affecting the circulation of air, thereby preventing light debris from overflowing from the stacking bin 407 and causing the debris to scatter. The card block at the bottom of the hollow plate 408 is connected to the card slot. By setting the card block, the card slot and the slide rail, the restriction of the hollow plate 408 can be well completed, and the fitting effect between the hollow plate 408 and the stacking bin 407 is guaranteed.
[0047] By setting the transmission member 402 and the fan blade 404, when the motor 301 drives the output shaft 302 to rotate, the output shaft 302 will drive the fan blade 404 to rotate through the transmission member 402. At this time, the fan blade 404 will blow the outside air into the interior of the bin body 1, and when the output shaft 302 rotates, it will drive the crushing roller 303 to rotate and crush the material. The crushed material will fall through the crushing roller 303. At this time, the air blown in by the fan blade 404 will separate the light debris generated in the crushing process from the raw materials, and blow the light debris into the interior of the stacking bin 407, thereby solving the problem that the existing multi-layer screening device cannot separate the light debris in the raw materials.
[0048] By setting up the stacking bin 407 and the hollow plate 408, when the light debris is blown into the interior of the stacking bin 407 under the action of the fan blades 404, the hollow plate 408 will block the light debris, and the air entering and leaving the stacking bin 407 will be discharged through the hollow plate 408. The setting of the stacking bin 407 can centrally process the light debris, avoiding the problem of scattered light debris and inconvenient collection. At the same time, the stacking bin 407 is installed inside the sliding frame 406 by sliding. After the collection of the light debris is completed, it is convenient to take out the stacking bin 407 and replace it, and the operation is simple and convenient.
[0049] When the raw materials are crushed by the crushing roller 303, the output shaft 302 drives the fan blade 404 to rotate through the transmission member 402, blowing the outside air into the interior of the bin body 1. At this time, the light debris inside the crushed raw materials will move to the interior of the stacking bin 407 under the action of the air blown in by the fan blades, and will be blocked by the hollow plate 408, thereby completing the separation and collection of the light debris.
[0050] The screening assembly 5 includes a multi-layer screening bin 501, a bent rod 502, a cam 503, a limit plate 504, a spring push rod 505 and a guide plate 506. The multi-layer screening bin 501 is located inside the bin body 1, the bent rod 502 is fixedly connected to the top of the multi-layer screening bin 501, the cam 503 is fixedly connected to the outer wall of the output shaft 302, the limit plate 504 is fixedly connected to the inner wall of the bin body 1, the spring push rod 505 is fixedly connected to the bottom of the inner wall of the bin body 1, and the guide plate 506 is fixedly connected to the outer wall of the bin body 1.
[0051] It needs to be further explained that: the outer wall of the multi-layer screening bin 501 is slidably connected to the inner wall of the bin body 1, and the top of the bent rod 502 is located within the rotation diameter of the cam 503. When the output shaft 302 drives the cam 503 to rotate, the cam 503 can push the bent rod 502 to descend, so that the bent rod 502 drives the multi-layer screening bin 501 to move. At this time, the multi-layer screening bin 501 will accelerate the screening efficiency of the internal raw materials, the bottom of the limiting plate 504 abuts against the top of the bent rod 502, and the top of the spring push rod 505 is fixedly connected to the bottom of the multi-layer screening bin 501. After the cam 503 is separated from the bent rod 502, the spring push rod 505 pushes the multi-layer screening bin 501 to reset, so that the bent rod 502 contacts and collides with the limiting plate 504, which can make the raw materials inside the multi-layer screening bin 501 shake, thereby avoiding the raw materials from being stuck inside the sieve hole and causing the sieve hole to be blocked.
[0052] The crushed raw materials are accumulated on the top of the multi-layer screening bin 501. When the output shaft 302 rotates, it drives the cam 503 to rotate. During the rotation, the cam 503 will periodically contact the top of the curved rod 502 and push the curved rod 502 to descend. During the descent of the curved rod 502, the multi-layer screening bin 501 will be driven to descend and exert pressure on the spring push rod 505. When the cam 503 is separated from the curved rod 502, the spring push rod 505 will push the multi-layer screening bin 501 to reset, so that the curved rod 502 contacts and collides with the limit plate 504. The impact force generated will cause the multi-layer screening bin 501 to shake. When the multi-layer screening bin 501 shakes, it will screen the crushed raw materials. After screening, the raw materials will flow out through the guide plates 506 on different sides according to their size.
[0053] By setting the cam 503 and the spring push rod 505, when the output shaft 302 rotates, the cam 503 will be driven to rotate. After the cam 503 rotates to a certain angle, the bent rod 502 will be pushed to move, so that the multi-layer screening bin 501 will descend and pressure will be applied to the spring push rod 505. When the cam 503 is separated from the bent rod 502, the spring push rod 505 will push the multi-layer screening bin 501 and the bent rod 502 to reset until they abut against the bottom of the limit plate 504. The collision impact force generated when the bent rod 502 contacts the limit plate 504 will drive the multi-layer screening bin 501 to shake, thereby improving the screening effect of the multi-layer screening bin 501 on the crushed raw materials.
[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
