Description

Technical Field

[0001] The invention relates to the technical field of clay brick screening, in particular to a waste clay brick crushing and screening device and a use method thereof. Background Art

[0002] Crushing and screening of waste clay bricks is an important part of resource recycling. First, waste clay bricks are collected and sent to the crushing equipment, where they are broken into smaller particles by mechanical force. Then, the crushed materials enter the screening system, where screens with different apertures are used to classify the materials according to particle size. Smaller particles can be used to make recycled bricks, road base materials, etc., while larger particles can be further crushed or used for other purposes. This process not only reduces the pollution of construction waste to the environment, but also realizes the recycling of resources, with significant economic and environmental benefits.

[0003] Usually clay brick recycling needs to be crushed and screened before use.

In the clay sand multi-layer screening device, the control panel is electrically connected to the motor, and the start and shut down of the device can be controlled by the control panel, which is very convenient, and a rack and a gear are arranged, the rack and the gear are adapted, and the motor starts the gear to rotate to drive the rack to move radially, the principle is simple, and maintenance is convenient. In the rising equipment, the material is screened only by the screen plate. After long-term use, it is easy to cause material accumulation on the surface of the screen plate, affecting the screening efficiency. Cleaning the material accumulation on the screen plate increases the labor intensity. The screen is easy to wear during use and needs to be replaced frequently, which increases the maintenance cost. The large particles that fall from the screen are not easy to effectively collect and re-crush, resulting in material waste.

[0016] The method for using the waste clay brick crushing and screening device comprises the following steps: S1. The waste clay bricks to be crushed and screened enter from the input hopper and fall into the crushing shell. The driving motor drives the meshing gear to rotate. The meshing gears on both sides rotate in opposite directions, and the crushing wheel rotates in the opposite direction. The waste clay bricks falling into the crushing shell are crushed and continue to be transported to the guide shell. The front and rear bottom of the guide shell are respectively paved with a front screen composed of a front screening frame A and a rear screening frame A, and a rear screen composed of a front screening frame B and a rear screening frame B. The crushed clay bricks fall into the front screen under the action of the guide groove for screening. The particles of qualified size pass through, while the oversized particles stay on the screen. One of the meshing gears will drive the driven sprocket to rotate under the action of the input pulley, the connecting belt and the output pulley during the rotation process, and continuously transmit the conveying chain; S2. The front screening frame A and the rear screening frame A and the front screening frame B and the rear screening frame B all form a screen. The sizes of the two groups of screens are different, and the two groups of screens are used alternately. The front screening frame A and the rear screening frame A are connected by a frame connecting rod and a frame return spring. When the screen composed of the front screening frame A and the rear screening frame A is located at the bottom of the guide shell, it is also located on the detection lifting frame. When the number of unqualified large particles on the screen increases, the weight increases, which will press down the screen composed of the front screening frame A and the rear screening frame A, driving the movable connecting column and the active top block to descend. During the descent of the active top block, the driven top block in front will be pushed open until the quick-connect buckle on the driven top block is stuck in the chain slot on the front conveying chain. At this time, the conveying chain will pull the front screening frame A, and the rotating disk on the front screening frame A is stuck in the guide rail base through the turntable limit block to limit the moving path. The ball-touching convex is also stuck in the path groove, supporting and limiting the moving path at both ends at the same time, and the conveying chain only plays a traction role to complete the rectangular moving path. The rotating disk is slidably connected with the front screening frame A, and the rotation of the rotating disk will not affect the front screening frame A, and the front screening frame A will not rotate to cause the clay bricks to fall. After the front screening frame A is pulled and moved, the rear front screening frame B is pulled under the action of magnetic suction to take over the screening work, so that the screening will not be interrupted when the screen is replaced. Since the sizes of the two groups of screens of the front screening frame A and the front screening frame B are different, the number of detection lifting frames is two, which support the two groups of screens respectively, and will not affect each other. After the front screening frame A presses down the detection lifting frame, the front screening frame B still maintains its height, and when the front screening frame A passes through the blocking block, the front screening frame B will be blocked by the blocking block and remain in place, and the front screening frame A is transported to the top for subsequent steps; S3. The front screening frame A rises vertically and first contacts the front hopper slot. The front hopper slot and the front hopper frame are hinged at the top, and the bottom is supported by a limit bracket. When the front screening frame A rises, the front hopper slot folds upward without affecting the passage of the front screening frame A, and is reset by the hopper reset spring after passing. When the front screening frame A is transferred to the other side and descends, it contacts the rear hopper slot. The rear hopper slot and the rear hopper frame are hinged at the bottom and are also maintained by the hopper reset spring. The rear hopper slot and the top of the rear hopper frame are blocked by their own shells and cannot be folded upward. When the screening frame A descends, it presses down the rear hopper slot and resets it after passing through. The front screening frame A continues to move in a rectangular path until it contacts the reset splint. The inside of the reset slot is an inclined surface. After the quick-connect buckle contacts the reset slot, it will be gradually pressed down until it is separated from the chain slot. The driven top block installed with the quick-connect buckle is pulled back by the top block reset spring and is no longer connected to the chain slot. At this time, the front screening frame A returns to the bottom of the guide shell again and contacts the front screening frame B at the same time, completing a transfer process, waiting for the front screening frame B to transfer and then take over the screening of the front screening frame B; S4. The top driven sprocket will drive the vibration cam to rotate during the rotation process, and continuously lift the vibration arm. The vibration arm is connected to the vibration guide rail, and the sliding connection between the guide rail base and the vibration guide rail can change the spacing, and a guide rail vibration spring is provided at the connection to amplify the vibration effect. The bottom path plate and the vibration path plate are also slidably connected to change the spacing, and a path vibration spring is provided to amplify the vibration effect. During the lateral movement of the front screening frame A and the rear screening frame A at the top, they will first be affected by the vibration effect of the vibration guide rail and the vibration path plate. After the rear screening frame A contacts the vibration path plate, it will be squeezed and close to the front screening frame A to cut off the larger particles on the surface. To prevent it from getting stuck in the mesh of the screen, the contact ball convex on the rear screening frame A contacts the path groove, and the path groove will drive the contact ball convex to rotate 180 degrees to make the rear screening frame A flip over, and under the action of cutting and vibration, the large clay brick particles on the surface of the screen will fall into the front hopper groove and the rear hopper groove, and then fall into the crushing shell for crushing. The front screening frame A and the rear screening frame A are no longer squeezed after passing through the vibrating path plate, and the frame reset spring drives the front screening frame A and the rear screening frame A to separate again. In the next cycle, since the front screening frame A and the rear screening frame A are flipped 180 degrees, screening is carried out on the other side of the screen to disperse the wear on both sides.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the cooperation of the screening mechanism and the circulating conveying mechanism, two groups of screening frames are used alternately, and the crushed clay bricks fall onto the screen composed of the front screening frame A and the rear screening frame A for screening, and qualified particles pass through the screen, and unqualified large particles remain on the screen. When too many large particles accumulate on the screen, the screening frame presses down the detection lifting frame to trigger the conveying chain to pull the screening frame to move. After the screening frame A moves, the front screening frame B takes over for screening. The two groups of screening frames work alternately to ensure that the screening process is uninterrupted. By alternating the use of the two groups of screening frames, the screening efficiency is improved, and the wear of the screen is reduced, thereby extending the service life of the equipment. The entire device realizes automatic screening and crushing through the mutual cooperation of mechanical structures, reduces manual operations, and improves production efficiency and safety.

[0018] In the present invention, through the cooperation of the internal hopper mechanism and the circulating conveying mechanism, when too many large-particle clay bricks accumulate on the screening frame, the screening frame will press down the detection lifting frame due to the increased weight, triggering the quick-connect buckle on the driven top block to connect with the chain slot, and the conveying chain pulls the screening frame along a predetermined path through the chain slot to complete the transfer of the screening frame. When the front screening frame A or the rear screening frame A passes through the front hopper slot or the rear hopper slot during the ascent or descent process, the hopper slot will be folded or pressed down according to the movement direction of the screening frame, and the internal hopper mechanism collects the large-particle clay bricks that fall from the screening frame, and guides them to the crushing shell for re-crushing, thereby reducing material waste and improving resource utilization.

[0019] In the present invention, through the cooperation of the path control mechanism and the circulating conveying mechanism, when the screening frame moves laterally at the top, the vibration of the vibrating guide rail and the vibrating path plate will cut off the large-particle clay bricks on the surface of the screen to prevent them from being stuck in the mesh of the screen. The contact ball convex on the rear screening frame contacts the path groove, and the path groove drives the contact ball convex to rotate 180 degrees, so that the rear screening frame flips over. The path control mechanism disperses the wear of the screen through the vibration and flipping functions, thereby extending the service life of the screen and reducing the equipment maintenance cost.

[0035] The method for using the waste clay brick crushing and screening device comprises the following steps: S1. The waste clay bricks to be crushed and screened enter from the input hopper 11 and fall into the crushing shell 2. The driving motor 23 drives the meshing gear 24 to rotate. The meshing gears 24 on both sides rotate in opposite directions, and the crushing wheel 241 rotates in the opposite direction. The waste clay bricks falling into the crushing shell 2 are crushed and continue to be transported to the guide shell 21. The front and rear bottoms of the guide shell 21 are respectively paved with a front screen composed of a front screening frame A54 and a rear screening frame A55, and a rear screen composed of a front screening frame B57 and a rear screening frame B58. The crushed clay bricks fall onto the front screen under the action of the guide groove 211 for screening. The qualified particles pass through while the oversized particles stay on the screen. During the rotation process, one of the meshing gears 24 drives the driven sprocket 42 to rotate under the action of the input pulley 25, the connecting belt 251 and the output pulley 252, and continuously transmits the conveying chain 43. S2, the front screening frame A54 and the rear screening frame A55 and the front screening frame B57 and the rear screening frame B58 all form a screen. The sizes of the two groups of screens are different. The two groups of screens are used alternately. The front screening frame A54 and the rear screening frame A55 are connected by a frame connecting rod 541 and a frame return spring 5411. When the screen composed of the front screening frame A54 and the rear screening frame A55 is located at the bottom of the guide shell 21, it is also located on the detection lifting frame 531. When the number of unqualified large particles on the screen increases, the weight increases. The screen composed of the front screening frame A54 and the rear screening frame A55 will be pressed down, driving the movable connecting column 542 and the active top block 5421 to descend. During the descent of the active top block 5421, the driven top block 544 in front will be pushed open until the quick-connect buckle 5444 on the driven top block 544 is inserted into the chain slot 44 on the front conveying chain 43. At this time, the conveying chain 43 will pull the front screening frame A54, and the rotating disk 543 on the front screening frame A54 will be stuck in the guide rail base 61 through the turntable limit block 611 to limit the moving path. The contact ball protrusion 561 on the rear screening frame A55 is also stuck in the path groove 6222, supporting and limiting the moving path at both ends at the same time. The conveying chain 43 only plays a traction role to complete the rectangular moving path. The rotating disk 543 is slidably connected with the front screening frame A54. The rotation of the rotating disk 543 will not affect the front screening frame A54. The front screening frame A54 will not rotate to cause the clay bricks to fall. After the front screening frame A54 is pulled and moved, it pulls the rear front screening frame B57 under the action of magnetic attraction to take over the screening. Working, so that the screening will not be interrupted when the screen is replaced. Since the sizes of the two groups of screens of the front screening frame A54 and the front screening frame B57 are different, the number of the detection lifting frame 531 is two, which respectively supports the two groups of screens and will not affect each other. After the front screening frame A54 presses down the detection lifting frame 531, the front screening frame B57 still maintains its height, and when the front screening frame A54 passes through the blocking block 52, the front screening frame B57 will be blocked by the blocking block 52 and remain in place, and the front screening frame A54 is transported to the top for subsequent steps; S3, the front screening frame A54 rises vertically and first contacts the front hopper slot 312, the front hopper slot 312 and the front hopper frame 31 are hinged at the top, and the bottom is supported by the limit bracket 313, when the front screening frame A54 rises, the front hopper slot 312 folds upward without affecting the passage of the front screening frame A54, and is reset by the hopper reset spring 33 after passing through, and the front screening frame A54 is transferred to the other side and contacts the rear hopper slot 322 when it descends, the rear hopper slot 322 and the rear hopper frame 32 are hinged at the bottom, and are also maintained by the hopper reset spring 33, the rear hopper slot 322 and the top of the rear hopper frame 32 are blocked by their own shells and cannot be folded upward, the front screening frame When the frame A54 descends, it presses down the rear hopper slot 322 and resets it after passing through. The front screening frame A54 continues to move in a rectangular path until it contacts the reset clamp 45. The interior of the reset slot 451 is an inclined surface. After the quick-connect buckle 5444 contacts the reset slot 451, it will be gradually pressed down until it is separated from the chain slot 44. The driven top block 544 installed with the quick-connect buckle 5444 is pulled back by the top block reset spring 5441 and is no longer connected to the chain slot 44. At this time, the front screening frame A54 returns to the bottom of the guide shell 21 again, and contacts the front screening frame B57 at the same time, completing a transfer process, waiting for the front screening frame B57 to transfer and then take over the screening of the front screening frame B57; S4. The top driven sprocket 42 will drive the vibration cam 631 to rotate during the rotation, and continuously lift the vibration arm 63. The vibration arm 63 is connected to the vibration guide rail 6114, and the sliding connection between the guide rail base 61 and the vibration guide rail 6114 can change the spacing, and a guide rail vibration spring 6112 is provided at the connection to amplify the vibration effect. The bottom path plate 62 and the vibration path plate 622 are also slidably connected to change the spacing, and a path vibration spring 6211 is provided to amplify the vibration effect. During the lateral movement of the front screening frame A54 and the rear screening frame A55 at the top, they will first be affected by the vibration effect of the vibration guide rail 6114 and the vibration path plate 622. After the rear screening frame A55 contacts the vibration path plate 622, it will be squeezed and close to the front screening frame A54 to separate the larger particles on the surface. The particles are cut off to prevent them from getting stuck in the mesh of the screen, and the contact ball protrusion 561 on the rear screening frame A55 contacts the path groove 6222. The path groove 6222 will drive the contact ball protrusion 561 to rotate 180 degrees to make the rear screening frame A55 flip over, and under the action of cutting and vibration, the large clay brick particles on the surface of the screen fall into the front hopper groove 312 and the rear hopper groove 322, and fall into the crushing shell 2 again for crushing. The front screening frame A54 and the rear screening frame A55 are no longer squeezed after passing through the vibrating path plate 622, and the frame reset spring 5411 drives the front screening frame A54 and the rear screening frame A55 to separate again. In the next cycle, since the front screening frame A54 and the rear screening frame A55 are flipped 180 degrees, screening is carried out on the other side of the screen to disperse the degree of wear on both sides.

During the rotation process, one of the meshing gears (24) drives the driven sprocket (42) to rotate through the input pulley (25), the connecting belt (251) and the output pulley (252), and continuously transmits the conveyor chain (43); S2, the front screening frame A (54) and the rear screening frame A (55) and the front screening frame B (57) and the rear screening frame B (58) all form a screen. The sizes of the two sets of screens are different. The two sets of screens are used alternately. The front screening frame A (54) and the rear screening frame A (55) are connected by a frame connecting rod (541) and a frame return spring (5411). When the screen formed by the front screening frame A (54) and the rear screening frame A (55) is located at the bottom of the guide housing (21), it is also located on the detection lifting frame (531). When the number of unqualified large particles on the screen increases, the weight increases, which will The screen formed by the front screening frame A (54) and the rear screening frame A (55) is pressed down, driving the movable connecting column (542) and the active top block (5421) to descend. During the descending process of the active top block (5421), the driven top block (544) in front is pushed open until the quick-connect buckle (5444) on the driven top block (544) is inserted into the chain slot (44) on the front conveying chain (43). At this time, the conveying chain (43) pulls the front screening frame A (54), and the rotating disk (543) on the front screening frame A (54) is inserted into the guide rail base (61) through the rotating disk limit block (611) to limit the rotation of the front screening frame A (54). The contact ball protrusion (561) on the rear screening frame A (55) is also stuck in the path groove (6222), supporting and limiting the moving path at both ends at the same time. The conveying chain (43) only plays a traction role to complete the rectangular moving path. The rotating disk (543) and the front screening frame A (54) are slidably connected. The rotation of the rotating disk (543) will not affect the front screening frame A (54). The front screening frame A (54) will not rotate to cause the clay bricks to fall. After the front screening frame A (54) is pulled and moved, it pulls the rear front screening frame B (57) under the action of magnetic attraction to replace it. The screening operation is performed so that the screening is not interrupted when the screen is replaced. Since the sizes of the two groups of screens of the front screening frame A (54) and the front screening frame B (57) are different, the number of the detection lifting frames (531) is two, which respectively support the two groups of screens and do not affect each other. After the front screening frame A (54) presses down the detection lifting frame (531), the front screening frame B (57) still maintains its height, and when the front screening frame A (54) passes through the blocking block (52), the front screening frame B (57) will be blocked by the blocking block (52) and remain in place, and the front screening frame A (54) is transferred to the top for subsequent steps; S3, the front screening frame A (54) rises vertically and first contacts the front hopper slot (312). The front hopper slot (312) and the front hopper frame (31) are hinged at the top, and the bottom is supported by the limit bracket (313). When the front screening frame A (54) rises, the front hopper slot (312) folds upward without affecting the passage of the front screening frame A (54), and is reset by the hopper reset spring (33) after passing through. When the front screening frame A (54) is transferred to the other side and descends, it contacts the rear hopper slot (322). The rear hopper slot (322) and the rear hopper frame (32) are hinged at the bottom and are also maintained by the hopper reset spring (33). The top of the rear hopper slot (322) and the rear hopper frame (32) are blocked by their own shells and cannot be folded upward. When A (54) descends, it presses down the rear hopper slot (322) and resets it after passing through. The front screening frame A (54) continues to move in a rectangular path until it contacts the reset clamp (45). The interior of the reset slot (451) is an inclined surface. After the quick-connect buckle (5444) contacts the reset slot (451), it will be gradually pressed down until it is separated from the chain slot (44). The driven top block (544) installed with the quick-connect buckle (5444) is pulled back under the action of the top block reset spring (5441) and is no longer connected to the chain slot (44). At this time, the front screening frame A (54) returns to the bottom of the guide housing (21) again and contacts the front screening frame B (57) at the same time, completing a transfer process, waiting for the front screening frame B (57) to transfer and then take over the screening of the front screening frame B (57); S4. The top driven sprocket (42) drives the vibration cam (631) to rotate during the rotation process, and continuously lifts the vibration arm (63). The vibration arm (63) is connected to the vibration guide rail (6114), and the guide rail base (61) and the vibration guide rail (6114) are slidably connected to change the spacing, and a guide rail vibration spring (6112) is provided at the connection to amplify the vibration effect. The bottom path plate (62) and the vibration path plate (622) are also slidably connected to change the spacing, and a path vibration spring (6211) is provided to amplify the vibration effect. During the top lateral movement, the front screening frame A (54) and the rear screening frame A (55) are firstly affected by the vibration guide rail (6114) and the vibration path plate (622). After the rear screening frame A (55) contacts the vibration path plate (622), it is squeezed and thus close to the front screening frame A (54) to make the surface larger. The particles are cut off to prevent them from getting stuck in the mesh of the screen, and the contact ball protrusion (561) on the rear screening frame A (55) contacts the path groove (6222), and the path groove (6222) drives the contact ball protrusion (561) to rotate 180 degrees, so that the rear screening frame A (55) turns over, and under the action of cutting and vibration, the large clay brick particles on the surface of the screen fall into the front hopper groove (312) and the rear hopper groove (322), and then fall into the crushing shell (2 ) is crushed, and the front screening frame A (54) and the rear screening frame A (55) are no longer squeezed after passing through the vibration path plate (622). The frame return spring (5411) drives the front screening frame A (54) and the rear screening frame A (55) to separate again. In the next cycle, since the front screening frame A (54) and the rear screening frame A (55) are flipped 180 degrees, the other side of the screen is used for screening, thereby dispersing the wear degree of both sides.
