Description
Technical Field
[0001] This utility model relates to the technical field of screening equipment, specifically a screening device for raw materials used in the production of environmentally friendly non-fired bricks. Background Technology
[0002] A new type of wall material made without high-temperature calcination using fly ash, coal slag, coal gangue, tailings slag, chemical slag, or natural sand, marine mud, etc. (one or more of the above raw materials) as the main raw materials is called non-fired brick.
[0003] Utility model patent CN218945146U discloses a raw material screening device for the production of environmentally friendly non-fired bricks, belonging to the technical field of screening equipment. It addresses the problem in existing technologies where, after screening coal slag, slag with unqualified particle diameters can be crushed into qualified slag for use, but slag with excessively large particle diameters must first be conveyed to a crushing mechanism for crushing, thus affecting the overall screening efficiency. The device includes a base plate, on which a mounting shell is installed, and a screening box is installed on the mounting shell. The bottom wall of the screening box has several screening holes. In this invention, the crushing roller, during its lateral movement following the two mounting plates, is obstructed by the coal slag, allowing the crushing roller to rotate and crush the coal slag particles with excessive diameter in the screening box. This crushes the coal slag particles to a size that can pass through the screening holes on the bottom wall of the screening box, thus completing the screening of the coal slag in one step. Furthermore, the simultaneous crushing of the coal slag particles reduces the defect rate. The simultaneous screening and crushing not only ensures the efficiency of coal slag screening but also reduces the defect rate by crushing the coal slag.
[0004] However, the above patent still has shortcomings: the patent uses a combination of a vacuum cleaner and a dust collection box to collect the dust generated during the crushing of coal slag. Due to the fast crushing speed, the dust spreads faster, and the suction power of the vacuum cleaner is relatively limited, only able to collect most of the dust. A small amount of dust spreads into the air, affecting the health of the workers. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:
[0027] A raw material screening device for the production of environmentally friendly non-fired bricks includes: a screening box 1; a feed pipe 2 is fixedly connected to the center of one side of the screening box 1; a storage box 3 is fixedly connected to the top of the feed pipe 2 at the end away from the screening box 1; a feed inlet 4 is fixedly connected to the bottom of the storage box 3; the bottom end of the feed inlet 4 is fixedly connected to the feed pipe 2; a first rotating shaft 5 is rotatably connected inside the feed pipe 2; the end of the first rotating shaft 5 away from the feed pipe 2 is rotatably connected to the screening box 1; a crushing mechanism 6 for screening coal slag is provided on the outer surface of the first rotating shaft 5 inside the screening box 1. The bottom of the screening box 1 is equipped with a discharge mechanism 7 to prevent coal slag blockage. The user pours the coal slag into the storage box 3. The coal slag inside the storage box 3 enters the inlet pipe 2 through the inlet 4. Then, the first rotating shaft 5 is controlled to rotate. While the first rotating shaft 5 is rotating, it continuously transports the coal slag inside the storage box 3 to the screening box 1. Then, the coal slag is crushed and screened by the crushing mechanism 6. The qualified coal slag falls to the bottom of the screening box 1. Then, the staff can control the qualified coal slag to be discharged to the outside of the device through the discharge mechanism 7.
[0028] like Figures 2 to 4As shown, the crushing mechanism 6 includes: a first rotating shaft 5 located inside the screening box 1, on the outer surface of which four circular plates 8 are evenly arranged; three second rotating shafts 9 are interleaved and fixedly connected between the four circular plates 8; rotating rods 10 are rotatably connected to the outer surface of the middle of each of the second rotating shafts 9; hammers 11 are fixedly connected to the ends of the rotating rods 10 away from the second rotating shafts 9; an arc-shaped plate 12 is arranged inside the screening box 1; a plurality of screen holes 13 are evenly opened in the middle of the arc-shaped plate 12; the arc-shaped plate 12 cooperates with the hammers 11; the arc-shaped plate... 12 is fixedly connected to the screening box 1. While the first rotating shaft 5 rotates, it drives the circular plate 8. While the circular plate 8 rotates, it drives the second rotating shaft 9 to rotate. While the second rotating shaft 9 rotates, the centrifugal force drives the rotating rod 10 to unfold and rotate. While the rotating rod 10 rotates, it drives the hammer 11 to rotate inside the screening box 1. When the hammer 11 rotates inside the screening box 1, it can continuously knock and crush the coal slag on the arc plate 12. The coal slag with qualified volume falls through the screen hole 13 to the bottom of the screening box 1 for storage.
[0029] like Figure 2 and Figure 6 As shown, annular triangular plates 14 are provided on both sides of the top of the arc plate 12. The annular triangular plates 14 are fixedly connected to the arc plate 12 and the screening box 1, which can effectively avoid the problem of broken dead corners inside the screening box 1.
[0030] like Figure 2 and Figure 4 As shown, the end of the first rotating shaft 5 away from the screening box 1 passes through the feed pipe 2 and extends to the first motor 15. The first motor 15 is fixedly connected to the feed pipe 2, and the first rotating shaft 5 is fixedly connected to the output end of the first motor 15. The outer surface of the first rotating shaft 5 located inside the feed pipe 2 is fixedly connected to the first auger blade 16. The first auger blade 16 is adapted to the feed pipe 2. When the first motor 15 is started, the output end of the first motor 15 drives the first rotating shaft 5 to rotate. While the first rotating shaft 5 rotates, it drives the first auger blade 16. The first auger blade 16 continuously conveys coal slag into the interior of the screening box 1 through the cooperation of the feed pipe 2.
[0031] like Figure 5As shown, the discharge mechanism 7 includes: a discharge port 17 is provided at the bottom of the screening box 1; a discharge pipe 18 is fixedly connected to the screening box 1 near the discharge port 17; a third rotating shaft 19 is provided inside the discharge pipe 18; one end of the third rotating shaft 19 passes through the discharge pipe 18 and extends to the second motor 20; the second motor 20 is fixedly connected to the discharge pipe 18; the third rotating shaft 19 is fixedly connected to the output end of the second motor 20; a second auger blade 21 is fixedly connected to the outer surface of the third rotating shaft 19 located inside the discharge pipe 18; the second auger blade 21 is adapted to the discharge pipe 18; the user can start the second motor 20; the output end of the second motor 20 drives the third rotating shaft 19; the output end of the third rotating shaft 19 drives the second auger blade 21; while the second auger blade 21 rotates, it can transport the coal slag stored at the bottom of the screening box 1 to the outside of the device through the discharge pipe 18.
[0032] like Figure 1 and Figure 2 As shown, a rectangular frame 22 is fixedly connected to the outer surface of the screening box 1. Four support rods 23 are evenly arranged at the bottom of the rectangular frame 22. The support rods 23 are all fixedly connected to the rectangular frame 22. The bottom of each support rod 23 is fixedly connected to a base 24. The bottom of each base 24 is fixedly connected to an anti-slip pad 25, which improves the stability of the device and prevents displacement caused by vibration during operation.
[0033] like Figure 1 As shown, a control box 26 with an internal touch screen is provided on one side of the top of the rectangular frame 22. The control box 26 is fixedly connected to the screening box 1, which makes it convenient for users to operate the device.
[0034] Working principle: The user pours coal slag into the storage bin 3. The coal slag inside the storage bin 3 enters the feed pipe 2 through the feed inlet 4. Then, the first motor 15 is started. The output end of the first motor 15 drives the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 drives the first auger blade 16. The first auger blade 16 continuously conveys coal slag into the screening box 1 through the feed pipe 2. At the same time, the rotation of the first rotating shaft 5 also drives the circular plate 8. The rotation of the circular plate 8 drives the second rotating shaft 9 to rotate. As the second rotating shaft 9 rotates, the centrifugal force drives the rotating rod 10 to unfold and rotate. The rotation of the rotating rod 10 drives the hammer 11 to rotate inside the screening box 1. When the hammer 11 rotates inside the screening box 1, it can continuously knock and crush the coal slag on the arc plate 12. Coal slag of the correct size falls through the screen holes 13 to the bottom of the screening box 1 for storage. Finally, the user can start the second motor 20. The output of the second motor 20 drives the third rotating shaft 19, and the output of the third rotating shaft 19 drives the second auger blade 21. While the second auger blade 21 rotates, it can transport the coal slag stored at the bottom of the screening box 1 to the outside of the device through the discharge pipe 18. Since the first auger blade 16 is installed inside the inlet pipe 2 and the second auger blade 21 is installed inside the outlet pipe 18, the environment for crushing coal slag is relatively sealed, which prevents the dust generated during coal slag crushing from spreading into the air outside the device. This effectively prevents workers from inhaling dust and solves the problem that existing raw material screening equipment for environmentally friendly non-fired brick production uses a combination of a vacuum cleaner and a dust collection box to collect dust generated during coal slag crushing. However, due to the fast crushing speed, the dust spreads faster, and the suction power of the vacuum cleaner is relatively limited, only able to collect most of the dust. A small amount of dust spreads into the air, affecting the health of workers.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
