Technical Field

[0001] The invention relates to the technical field of solid waste-based gel material pretreatment, in particular to a pretreatment device for producing road base solid waste gel. Background Art

[0002] Solid waste cementitious materials are materials that can bond granular materials or block materials into a whole and have a certain strength. Cementitious materials are widely used in construction projects. Most commonly used cementitious materials are inorganic mineral powders, while solid waste cementitious materials need to be pre-treated during preparation.

[0003] The Chinese patent with patent announcement number CN220835735U discloses an ultra-low carbon and ultra-low emission all-solid waste cementitious material grinding device, including a grinding component and a screening material cleaning component. The second motor on the grinding component controls the rotation of the grinding roller to grind the poured solid waste material; the processed solid waste material is filtered into the powder storage box through a vibrating screen, and some incompletely crushed solid residues remain on the screen; then the first motor of the screening material cleaning component is turned on to drive the threaded rod to rotate, so that the cleaning push block on the threaded rod moves outward and pushes out the solid residue on the screen together, and the cover is opened to recycle and clean the solid waste material at the cleaning port, and then pour it into the feed port for secondary grinding. This patent can greatly improve the qualified rate of powder materials by grinding and cleaning and collecting solid waste materials multiple times through the grinding device, which is more conducive to the application of solid waste materials.

[0004] However, the current pretreatment device has the following problems: the pretreatment device uses a manual method to put some incompletely crushed solid waste materials into the pretreatment device for a second time for grinding processing, but the manual operation method is time-consuming and easily limited by the operator's skills and physical strength, resulting in low processing efficiency.

The motor drives the rotating rod to rotate, and the rotating rod drives the pushing assembly to push the incompletely crushed solid waste materials on the surface of the inclined screen into the guide shell. The guide shell guides the incompletely crushed solid waste materials to the fixed cylinder. When the rotating rod rotates, it drives the spiral blades to rotate, and the spiral blades will transport and lift the incompletely crushed solid waste materials at the fixed cylinder upward until the incompletely crushed solid waste materials are re-discharged to the crushing roller group for crushing through the discharging device.

[0007] According to the above technical solution, the pusher assembly includes a bevel gear 1 and a reciprocating screw. The bevel gear 1 is fixed at the lower part of the outer wall of the rotating rod. The reciprocating screw penetrates horizontally and is rotatably installed at the lower inner wall of the device body. A bevel gear 2 is fixed at the outer wall of one side of the reciprocating screw. The bevel gear 1 meshes with the bevel gear 2. The external thread of the reciprocating screw is connected with a U-shaped frame. A sliding groove for sliding the U-shaped frame is opened at the outer wall of the device body. A connecting plate is fixed at the top of the inner wall of the U-shaped frame. A plug column is penetrated and slidably installed at the bottom of the connecting plate.

[0008] According to the above technical solution, L-shaped friction rods are fixed on both sides of the top of the inclined screen, a shaft rod is horizontally penetrated and rotatably installed at the lower outer wall of the notch plate, friction wheels are fixed at both ends of the shaft rod, and a plurality of toggle plates are evenly and equidistantly fixed on the outer wall of the shaft rod, and the plurality of toggle plates are respectively located between the notches of the notch plates, the top of the inner wall of the L-shaped friction rod is set as a rough surface, and the outside of the friction wheel is set as a rough surface. The rough surface of the L-shaped friction rod contacts the rough surface of the friction wheel, and when the notch plate is moved, the friction wheel will be driven to move by the shaft rod. Under the action of the friction force between the friction wheel and the L-shaped friction rod, the L-shaped friction rod drives the friction wheel to rotate, the friction wheel drives the shaft rod to rotate, and the shaft rod drives the toggle plate to rotate, so that the toggle plate pushes the incompletely crushed solid waste material stuck in the notch of the notch plate out of the notch of the notch plate.

[0009] According to the above technical solution, two screen devices are arranged outside the fixed cylinder, and the two screen devices include a side shell and an arc mesh plate. The arc mesh plate is embedded in the side of the fixed cylinder away from the device body, and the side shell is fixed on the side of the fixed cylinder away from the device body. A U-shaped discharge pipe is fixed at the bottom of the side shell, and a plurality of guide plates are evenly and equidistantly fixed on the inner wall of the side shell, and the guide plates are in contact with the outer wall of the arc mesh plate. When the spiral blades convey and lift the uncompletely crushed solid waste materials at the fixed cylinder upward, the completely crushed solid waste materials mixed in the uncompletely crushed solid waste materials in the fixed cylinder will pass through the arc mesh plate and fall into the side shell. The side shell guides the completely crushed solid waste materials in the fixed cylinder to the U-shaped discharge pipe for discharge. At the same time, the completely crushed solid waste materials will pass through the guide plate when passing through the arc mesh plate, and the guide plate will guide the completely crushed solid waste materials to the inner side of the side shell.

[0010] According to the above technical solution, a cavity is provided at the bottom of the rotating rod, a sliding column is slidably installed inside the cavity of the rotating rod, a spring is provided between the sliding column and the top of the inner wall of the cavity of the rotating rod, a plurality of fixed rods are vertically and evenly fixed on the outside of the rotating rod, arc plates are slidably installed on the outside of the plurality of fixed rods, a hinged rod is hinged on the side of the arc plate close to the rotating rod, a side of the hinged rod away from the arc plate is hinged to the outer wall of the sliding column, a sliding groove for the hinged rod to move is provided on the outside of the rotating rod, a fixed column is fixed on the outer wall below the sliding column, An L-shaped plate is fixed at the bottom of the U-shaped discharge pipe, and a triangular block is fixed at the top edge of the L-shaped plate. The inclined surface of the triangular block of the L-shaped plate is located on the movement trajectory of the fixed column. When the rotating rod rotates, it will drive the sliding column to rotate, and the sliding column drives the fixed column to rotate. When the fixed column rotates to the position of the inclined surface of the triangular block of the L-shaped plate, the inclined surface of the triangular block of the L-shaped plate pushes the fixed column to drive the sliding column to move upward, and the sliding column pushes the hinged rod to drive the arc plate to move along the outside of the fixed rod in the direction away from the rotating rod, so that the arc plate pushes the solid waste materials lifted by the spiral blade to flow toward the arc mesh plate.

An L-shaped inclined tube is fixed to the outside of the cavity ring, and the end of the L-shaped inclined tube away from the cavity ring is slidably installed in the strip groove of the sliding shell. A resistance column is fixed on the top of the L-shaped inclined tube, and the spring plate is fixed on the upper outer wall of the rotating rod. The resistance column is located on the movement trajectory of the spring plate. The solid waste material discharged from the fixed cylinder will be guided to the crushing roller through the cavity ring, the L-shaped inclined tube and the sliding shell. When the rotating rod rotates, the spring plate will be driven to rotate. When the spring plate rotates to the resistance column, the spring plate pushes the resistance column to drive the L-shaped inclined tube to swing. One end of the L-shaped inclined tube drives the cavity ring to rotate, and the other end of the L-shaped inclined tube drives the sliding shell to move to one side along the top of the device body. When the spring plate pushes the resistance column to move to the extreme position, the spring plate can no longer push the resistance column to move.

[0012] The present invention provides a pretreatment device for producing road base solid waste gel, which has the following beneficial effects:

[0013] (1) The present invention arranges a lifting device so that the inclined screen, the rotating rod, the guide shell, the fixed cylinder, and the pusher assembly cooperate to drive the spiral blade to convey and lift the incompletely crushed solid waste materials at the fixed cylinder upward, until the incompletely crushed solid waste materials are discharged to the crushing roller group for crushing through the discharging device, thereby realizing automatic secondary crushing of the incompletely crushed solid waste materials, significantly improving the solid waste material processing speed and production efficiency. At the same time, the notch of the notch plate in the pusher assembly can prevent a large amount of completely crushed solid waste materials from being pushed into the guide shell; at the same time, the notch plate, the shaft rod, the friction wheel, and the L-shaped friction rod cooperate to drive the toggle plate to push the incompletely crushed solid waste materials stuck at the notch of the notch plate out of the notch of the notch plate, thereby facilitating the completely crushed solid waste materials to pass through the notch of the notch plate, thereby preventing the notch of the notch plate from pushing a large amount of completely crushed solid waste materials into the guide shell.

[0014] (2) The present invention arranges two screening devices so that the completely crushed solid waste materials mixed in the uncompletely crushed solid waste materials in the fixed cylinder will pass through the arc screen plate and fall into the side shell for discharge. The completely crushed solid waste materials are discharged, which means that the crushing roller group does not need to process these solid waste materials that have reached the required particle size, thereby reducing the workload of the crushing roller group and improving the efficiency of secondary crushing of the uncompletely crushed solid waste materials. At the same time, the guide plate will guide the completely crushed solid waste materials to the inner side of the side shell, thereby avoiding the problem that the completely crushed solid waste materials affect the mesh surface in the area below the arc screen plate to screen out the completely crushed solid waste materials during the discharge process; at the same time, the rotating rod, sliding column, fixed column, L-shaped plate, hinged rod, and fixed rod cooperate to drive the arc plate to push the solid waste materials toward the arc screen plate, which can enhance the contact between the solid waste materials and the arc screen plate and improve the passing rate of small particles or fine solid waste materials.

[0015] (3) The present invention arranges a discharging device so that the fixed cylinder, the cavity ring, the L-shaped inclined tube and the sliding shell, the rotating rod and the spring plate cooperate to drive the sliding shell to dynamically sprinkle the incompletely crushed solid waste materials on the crushing roller group, so that the incompletely crushed solid waste materials can be evenly distributed on the crushing roller group, reducing local material accumulation or blockage, maintaining the uniform distribution of solid waste materials in the crushing area, and helping to improve the crushing quality of solid waste materials.

The reciprocating screw 48 is transversely penetrated and rotatably installed at the lower inner wall of the device body 1. A bevel gear 2 47 is fixed at the outer wall of one side of the reciprocating screw 48. The bevel gear 1 46 meshes with the bevel gear 2 47. The external thread of the reciprocating screw 48 is connected with a U-shaped frame 410. A slide groove for the U-shaped frame 410 to slide is opened at the outer wall of the device body 1. A connecting plate 41 is fixed to the top of the inner wall of the U-shaped frame 410. 2.

The rough surface of the L-shaped friction rod 417 contacts the rough surface of the friction wheel 413. Through the arrangement of the above structure, the toggle plate 416 pushes the incompletely crushed solid waste material stuck in the notch of the notch plate 414 out of the notch of the notch plate 414, thereby facilitating the completely crushed solid waste material to pass through the notch of the notch plate 414, thereby avoiding the notch of the notch plate 414 from pushing a large amount of completely crushed solid waste material into the guide shell 41.

[0031] The fixed cylinder 42 is provided with two screen devices 5 outside, and the two screen devices 5 include a side shell 51 and an arc mesh plate 54. The arc mesh plate 54 is embedded in the side of the fixed cylinder 42 away from the device body 1. The side shell 51 is fixed to the side of the fixed cylinder 42 away from the device body 1.

A plurality of guide plates 53 are evenly and equidistantly fixed to the inner wall of the side shell 51, and the guide plates 53 are in contact with the outer wall of the arc mesh plate 54. Through the arrangement of the above structure, the completely crushed solid waste material mixed in the incompletely crushed solid waste material in the fixed cylinder 42 can be removed. The material will pass through the arc mesh plate 54 and fall into the side shell 51 for discharge. The discharge of the completely crushed solid waste material means that the crushing roller group 2 does not need to process the solid waste materials that have reached the required particle size, thereby reducing the workload of the crushing roller group 2 and improving the efficiency of secondary crushing of the incompletely crushed solid waste materials. At the same time, the guide plate 53 will guide the completely crushed solid waste material to the inner side of the side shell 51, thereby avoiding the problem that the completely crushed solid waste material affects the mesh surface in the area below the arc mesh plate 54 to screen out the completely crushed solid waste material during the discharge process.

[0032] A cavity is provided at the bottom of the rotating rod 43, a sliding column 57 is slidably installed inside the cavity of the rotating rod 43, a spring is provided between the sliding column 57 and the top of the inner wall of the cavity of the rotating rod 43, a plurality of fixed rods 58 are fixed vertically and evenly at equal intervals outside the rotating rod 43, arc plates 59 are slidably installed outside the plurality of fixed rods 58, a hinged rod 510 is hinged on the side of the arc plate 59 close to the rotating rod 43, and a side of the hinged rod 510 away from the arc plate 59 is hinged to the outer wall of the sliding column 57, and a sliding hole for the hinged rod 510 to move is provided on the outside of the rotating rod 43. A fixed column 56 is fixed to the outer wall below the sliding column 57, an L-shaped plate 55 is fixed to the bottom of the U-shaped discharge pipe 52, a triangular block is fixed at the top edge of the L-shaped plate 55, and the inclined surface of the triangular block of the L-shaped plate 55 is located on the movement trajectory of the fixed column 56. Through the arrangement of the above structure, the arc plate 59 pushes the spiral blade 44 to convey and lift the solid waste material to the arc mesh plate 54. Pushing the solid waste material to the arc mesh plate 54 can enhance the contact between the solid waste material and the arc mesh plate 54, thereby improving the passing rate of small particles or fine solid waste materials.

[0033] When in use, solid waste materials are put into the device body 1, and the solid waste materials will fall on the crushing roller group 2, and the crushing roller group 2 will crush the solid waste materials. The crushed solid waste materials will fall on the inclined screen 49, and the vibration motor 45 will be started. The vibration motor 45 will drive the inclined screen 49 to vibrate, and the inclined screen 49 will screen the crushed solid waste materials, and the solid waste materials that are not completely crushed will be retained on the surface of the inclined screen 49. The motor drives the rotating rod 43 to rotate, and the rotating rod 43 will drive the pushing assembly to push the solid waste materials that are not completely crushed on the surface of the inclined screen 49 into the guide shell 41, and the guide shell 41 guides the incompletely crushed solid waste materials to the fixed cylinder 42, and the rotating rod 43 drives the spiral blade 44 to rotate when it rotates. The spiral blade 44 conveys and lifts the incompletely crushed solid waste materials in the fixed cylinder 42 upward until the incompletely crushed solid waste materials are re-discharged to the crushing roller group 2 through the discharging device 6 for crushing, thereby realizing automatic secondary crushing of the incompletely crushed solid waste materials, significantly improving the speed and production efficiency of processing solid waste materials. It is worth mentioning that the specific use steps of the pusher assembly are as follows: when the rotating rod 43 rotates, it drives the bevel gear 46 to rotate, and the bevel gear 46 rotates. 6 drives the bevel gear 2 47 to rotate, the bevel gear 2 47 drives the reciprocating screw 48 to rotate, the reciprocating screw 48 drives the U-shaped frame 410 to reciprocate, the U-shaped frame 410 drives the notch plate 414 to reciprocate along the top of the inclined screen 49 through the connecting plate 412 and the plug column 411, each time the notch plate 414 moves in the direction of the guide shell 41, the notch plate 414 will push the solid waste material that is not completely crushed into the guide shell 41, and the notch of the notch plate 414 can prevent a large amount of completely crushed solid waste material from being pushed into the guide shell 41; when the notch plate 414 moves in the direction of the guide shell 41, the notch of the notch plate 414 will drive the friction wheel through the shaft 415 413 moves accordingly, and under the action of the friction force between the friction wheel 413 and the L-shaped friction rod 417, the L-shaped friction rod 417 drives the friction wheel 413 to rotate, and the friction wheel 413 drives the shaft rod 415 to rotate, and the shaft rod 415 drives the toggle plate 416 to rotate, so that the toggle plate 416 pushes the incompletely crushed solid waste materials stuck in the notch of the notch plate 414 out of the notch of the notch plate 414, thereby facilitating the completely crushed solid waste materials to pass through the notch of the notch plate 414, thereby avoiding the notch of the notch plate 414 from pushing a large amount of completely crushed solid waste materials into the guide shell 41.

[0034] When the spiral blades 44 convey and lift the incompletely crushed solid waste materials in the fixed cylinder 42 upward, the completely crushed solid waste materials mixed in the incompletely crushed solid waste materials in the fixed cylinder 42 will pass through the arc mesh plate 54 and fall into the side shell 51. The side shell 51 guides the completely crushed solid waste materials in the fixed cylinder 42 to the U-shaped discharge pipe 52 for discharge. The discharge of the completely crushed solid waste materials means that the crushing roller group 2 does not need to process these solid waste materials that have reached the required particle size, thereby reducing the workload of the crushing roller group 2 and improving the efficiency of secondary crushing of the incompletely crushed solid waste materials. At the same time, the completely crushed solid waste materials will pass through the guide plate 53 when passing through the arc mesh plate 54. The guide plate 53 will guide the completely crushed solid waste materials to the inner side of the side shell 51, thereby This avoids the problem that the completely crushed solid waste materials affect the mesh surface in the area below the arc mesh plate 54 from screening out the completely crushed solid waste materials during the discharge process; when the rotating rod 43 rotates, it will drive the sliding column 57 to rotate, and the sliding column 57 drives the fixed column 56 to rotate. When the fixed column 56 rotates to the position of the triangular block inclined surface of the L-shaped disk 55, the triangular block inclined surface of the L-shaped disk 55 pushes the fixed column 56 to drive the sliding column 57 to move upward, and the sliding column 57 pushes the hinged rod 510 to drive the arc plate 59 to move along the outside of the fixed rod 58 away from the rotating rod 43, so that the arc plate 59 pushes the spiral blade 44 to convey and lift the solid waste materials to the arc mesh plate 54. Pushing the solid waste materials to the arc mesh plate 54 can enhance the contact between the solid waste materials and the arc mesh plate 54, thereby improving the pass rate of small particles or fine solid waste materials.

[0035] See also Figure 1 - Fig.10 On the basis of the above embodiment, in another embodiment of the present invention, the discharge device 6 includes a cavity ring 61, a sliding shell 63, and a spring plate 65. The sliding shell 63 is slidably mounted on one side of the top of the device body 1. A strip groove is provided on the top of the sliding shell 63. The cavity ring 61 is rotatably mounted on the upper outer wall of the fixed cylinder 42. A torsion spring is provided between the cavity ring 61 and the outer wall of the fixed cylinder 42. An L-shaped inclined tube 62 is fixed to the outside of the cavity ring 61. One end of the L-shaped inclined tube 62 away from the cavity ring 61 is slidably mounted on the strip groove of the sliding shell 63. Inside the L-shaped groove, a resistance column 64 is fixed on the top of the L-shaped inclined tube 62, and a spring plate 65 is fixed on the upper outer wall of the rotating rod 43. The resistance column 64 is located on the movement trajectory of the spring plate 65. Through the arrangement of the above structure, the sliding shell 63 dynamically sprinkles the incompletely crushed solid waste materials on the crushing roller group 2, so that the incompletely crushed solid waste materials can be evenly distributed on the crushing roller group 2, reducing local material accumulation or blockage, maintaining the uniform distribution of solid waste materials in the crushing area, and helping to improve the crushing quality of solid waste materials.

[0036] When in use, the solid waste materials discharged from the fixed cylinder 42 will be guided to the crushing roller group 2 through the cavity ring 61, the L-shaped inclined tube 62 and the sliding shell 63. When the rotating rod 43 rotates, the spring plate 65 will be driven to rotate. When the spring plate 65 rotates to the contact column 64, the spring plate 65 pushes the contact column 64 to drive the L-shaped inclined tube 62 to swing. One end of the L-shaped inclined tube 62 drives the cavity ring 61 to rotate, and the other end of the L-shaped inclined tube 62 drives the sliding shell 63 to move to one side along the top of the device body 1. When the spring plate 65 pushes the contact column 64 to move to the limit position, the spring plate 65 can no longer push the contact column 64. When the spring plate 65 is displaced, the spring plate 65 will pass over the abutment column 64. Under the elastic force of the torsion spring corresponding to the cavity ring 61, the cavity ring 61 drives the L-shaped inclined tube 62 to reset. The other end of the L-shaped inclined tube 62 drives the sliding shell 63 to reset and move along the top of the device body 1, and so on. As a result, the sliding shell 63 dynamically sprinkles the incompletely crushed solid waste materials on the crushing roller group 2, so that the incompletely crushed solid waste materials can be evenly distributed on the crushing roller group 2, reducing local accumulation or blockage, maintaining the uniform distribution of solid waste materials in the crushing area, and helping to improve the crushing quality of solid waste materials.
