Description

Technical Field

[0001] This invention relates to the field of ash and slag reprocessing technology, and in particular to an ash and slag reprocessing equipment. Background Technology

[0002] Ash slag, also known as slag or coal slag, is an environmentally friendly waste that can be recycled. In current technology, the secondary processing of ash slag mainly involves mixing it with other materials to make bricks. Since slag and coal slag have good permeability, bricks made from ash slag are mostly permeable bricks. Therefore, using ash slag to make permeable bricks is a relatively common ash slag reprocessing measure.

[0003] The process of reprocessing ash into permeable bricks includes three main parts: raw material mixing, pressing and molding, and subsequent water curing. Among them, the existing technology for water curing measures is mostly done by manual watering. Manual operation can often only water the surface of the permeable bricks. Since permeable bricks are often stacked into brick stacks after molding, manual watering will prevent the bricks inside the stack from effectively absorbing water, thus resulting in the water curing not achieving the expected technical effect and failing to meet the requirements. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned ash and slag reprocessing equipment, the present invention proposes an ash and slag reprocessing equipment to solve such problems.

[0006] The agitation unit includes a receiving plate rotatably connected to the curing tank, multiple sets of agitation rods evenly distributed around the receiving plate, a rectangular shaft vertically inserted into the center of the receiving plate, with the end of the rectangular shaft extending outward through the bottom of the curing tank, a gear disk located at the lower end of the rectangular shaft, and a drive gear located on the side of the gear disk, with the side of the drive gear perpendicular to the gear disk, and the gear disk meshing with the drive gear for transmission.

[0007] The limiting unit includes a tray rotatably connected to the top of a rectangular shaft, multiple sets of reset components equally distributed around the tray, and a limiting frame corresponding to each set of reset components vertically, with the limiting frame inserted into a guide groove.

[0008] As a preferred embodiment of the ash reprocessing equipment of the present invention, the curing tank is provided with a gantry crane, and the top two sides of the cage are sleeved on the gantry crane. Multiple sets of guide grooves are opened on the inner side of the bottom end of the cage, and the top of the limiting frame is inserted into the guide groove.

[0009] As a preferred embodiment of the ash reprocessing equipment of the present invention, wherein: a spherical protrusion with a hemispherical top is provided at the inner axial position of the curing tank, and the lower part of the receiving plate abuts against the spherical protrusion; a limiting groove is provided on the bottom side of the inner wall of the curing tank, and the outer end of the stirring rod extends into the limiting groove.

[0010] As a preferred embodiment of the ash and slag reprocessing equipment of the present invention, wherein: the receiving plate has inwardly recessed hemispherical grooves on both the upper and lower sides of the shaft; the rectangular shaft has a rectangular column structure and is inserted into the shaft of the receiving plate; the top of the rectangular shaft is provided with a limiting ball, and the limiting ball extends into the tray.

[0011] In a preferred embodiment of the ash and slag reprocessing equipment of the present invention, the end of the rectangular shaft is connected to an elastic support structure, and the outer end of the drive gear is connected to a drive mechanism.

[0012] As a preferred embodiment of the ash reprocessing equipment of the present invention, the stirring rod is in the form of an L-shaped structure, and the lower end of the L-shaped structure extends laterally outward to the inner wall of the curing tank.

[0013] In a preferred embodiment of the ash reprocessing equipment of the present invention, the outer wall of the limiting frame abuts against the inner side of the guide groove, the limiting frame includes multiple sets of limiting rods correspondingly inserted into multiple sets of guide grooves, and a connecting rod transversely arranged at the end of the multiple sets of limiting rods, and the connecting rod is fixedly connected to the reset component.

[0014] As a preferred embodiment of the ash reprocessing equipment of the present invention, the upper end of the limiting rod is wedge-shaped, and the inclined side of the wedge abuts against the inner side of the guide groove, while the inner side of the limiting rod is on the same vertical line.

[0015] As a preferred embodiment of the ash reprocessing equipment of the present invention, a spherical protrusion II is provided at the lower axial position of the tray, and the end of the spherical protrusion II is a hemispherical structure, and a slot is provided inside the spherical protrusion II.

[0016] In a preferred embodiment of the ash reprocessing equipment of the present invention, the resetting component includes an extension shaft fixedly connected to the tray, a connecting shaft inserted into the extension shaft and fixedly connected to the limiting frame, and a spring disposed between the connecting shaft and the extension shaft.

[0018] Meanwhile, an agitation unit is installed inside the curing pool to agitate the water flow, causing the water in the pool to flow and turbulent. The flow of water can accelerate the contact and exchange speed between the water and the permeable bricks, thereby improving the water absorption efficiency and shortening the soaking time of the brick stack. Moreover, the agitation unit can adaptively adjust the speed of the agitation water flow according to the actual size of the brick stack, ensuring that the water can fully penetrate into all parts of the brick stack.

[0019] Furthermore, a limiting unit is installed in the curing pool. The limiting unit can clamp the brick stacks immersed in the curing pool from all four directions, effectively preventing the bricks on the brick stacks from being swept off by the water flow during the stirring unit's stirring process, thus ensuring the stability of the brick stacks during the immersion curing process.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Reference Figures 1-8 According to an embodiment of the present invention, an ash reprocessing device is provided, including a curing tank 1, a hanging cage 12 is provided on the curing tank 1, and an agitation unit 2 and a limiting unit 3 are provided inside the curing tank 1.

[0033] Reference Figure 5The agitation unit 2 includes a receiving plate 21 rotatably connected to the curing tank 1, multiple sets of agitating rods 22 evenly distributed around the receiving plate 21, a rectangular shaft 23 vertically inserted into the center of the receiving plate 21, with the end of the rectangular shaft 23 extending outward through the bottom of the curing tank 1, a gear disk 25 located at the lower end of the rectangular shaft 23, and a drive gear 28 located on the side of the gear disk 25, with the side of the drive gear 28 perpendicular to the gear disk 25. The gear disk 25 and the drive gear 28 mesh and transmit power. The rotation of the receiving plate 21 drives the agitating rods 22 to agitate the water in the curing tank 1, thereby agitating the water flow within the curing tank 1. Agitation creates a flowing state of water, increasing the contact opportunity between the water and the permeable bricks, and promoting water circulation. The penetration of water accelerates the soaking efficiency of the brick stack. The gear disk 25 is perpendicular to the inclined side of the drive gear 28, so that the gear disk 25 will always maintain meshing with the drive gear 28 when it moves in the vertical direction. The drive gear 28 is thinner at the top and thicker at the bottom. Therefore, the diameter of the drive gear 28 increases from top to bottom. When the size of the gear disk 25 remains unchanged, the rotation amplitude is also different when the gear disk 25 and the drive gear 28 are in contact and meshing at different parts. When the gear disk 25 meshes with the part with the larger diameter of the drive gear 28, the gear disk 25 is driven by the drive gear 28 and rotates faster. When the gear disk 25 meshes with the part with the smaller diameter of the drive gear 28, the rotation speed of the gear disk 25 is slower.

[0034] Reference Figure 6 The limiting unit 3 includes a tray 31 rotatably connected to the top of the rectangular shaft 23, multiple sets of reset components 32 equally distributed around the tray 31, and a limiting frame 33 vertically disposed on each set of reset components 32. The limiting frame 33 is inserted into the guide groove 13. The rectangular shaft 23 elastically supports the four sets of limiting frames 33 on the four sides of the cage 12, thereby limiting the brick stacks on the cage 12 from all sides.

[0035] Among them, reference Figure 1 The maintenance pool 1 is equipped with a gantry crane 11, and the top two sides of the cage 12 are fitted onto the gantry crane 11. Multiple guide grooves 13 are opened on the inner side of the bottom end of the cage 12, and the top of the limiting frame 33 is inserted into the guide groove 13. The gantry crane 11 is equipped with a lifting device, which can drive the cage 12 to move vertically.

[0036] Among them, reference Figure 4 The curing tank 1 has a spherical protrusion 14 with a hemispherical top at the center of its internal axis. The receiving plate 21 rests on the spherical protrusion 14. A limiting groove 15 is opened on the bottom side of the inner wall of the curing tank 1. The outer end of the stirring rod 22 extends into the limiting groove 15. The spherical structure of the spherical protrusion 14 can optimize the connection between the receiving plate 21 and the curing tank 1. The limiting groove 15 is used to limit the stirring rod 22.

[0037] Among them, reference Figure 5 The receiving plate 21 has inwardly recessed hemispherical grooves 27 on both the upper and lower sides of its axis. The rectangular shaft 23 has a rectangular column structure and is inserted into the axis of the receiving plate 21. The top of the rectangular shaft 23 is provided with a limiting ball 24, which extends into the tray 31. The hemispherical grooves 27 can optimize the connection between the limiting units 3 and the limiting grooves 15 on the upper and lower sides of the stirring unit 2, making the stirring unit 2 rotate more smoothly. The limiting ball 24 works on the same principle as the groove 27, but the limiting ball 24 will maintain the connection between the tray 31 and the rectangular shaft 23, so that the two are connected in the vertical direction, but they will not hinder each other from rotating in a circular direction.

[0038] Furthermore, the rectangular shaft 23 of the rectangular column structure is connected to the receiving plate 21 by plugging. The two limit each other in the circumferential direction, so the rectangular shaft 23 can drive the receiving plate 21 to rotate synchronously, thereby driving the agitation unit 2 to perform agitation work as a whole. However, the two are slidably connected in the vertical direction, so the rectangular shaft 23 can move vertically at the axis position of the receiving plate 21. The spherical protrusion 14 has a slot with a diameter larger than the width of the rectangular shaft 23, so the rectangular shaft 23 passes through the spherical protrusion 14. However, the two do not limit each other in the circumferential direction, so the rectangular shaft 23 can rotate circumferentially in the spherical protrusion 14.

[0039] Furthermore, refer to Figure 5 The end of the rectangular shaft 23 is connected to an elastic support structure 26, and the outer end of the drive gear 28 is connected to a drive mechanism. The elastic support structure 26 can be selected according to actual needs, and can be a spring support structure or a hydraulic spring support structure. When the brick stack moves downward with the cage 12, the brick stack will compress the elastic support structure 26 by its own weight. When the pressure is removed, the elastic support structure 26 will rebound. The downward contraction of the elastic support structure 26 is determined by the mass of the brick stack. The drive gear 28 is driven by a rotating power source according to the usage requirements. It can be a motor, engine, etc., as long as it can drive the drive gear 28 to rotate.

[0040] Furthermore, referring to 2, the stirring rod 22 has an overall L-shaped structure, and the lower end of the L-shaped structure extends laterally outward to the inner wall of the curing tank 1. The L-shaped structure of the stirring rod 22 extends into the limiting groove 15, and is therefore limited by the vertical direction of the limiting groove 15, thereby keeping the stirring unit 2 in the designated position by the stirring rod 22.

[0041] Referring to the figure, the outer wall of the limiting frame 33 abuts against the inner side of the guide groove 13. The limiting frame 33 includes multiple sets of limiting rods 331 corresponding to the multiple sets of guide grooves 13, and connecting rods 332 horizontally arranged at the ends of the multiple sets of limiting rods 331. The connecting rods 332 are fixedly connected to the reset component 32. There are four sets of limiting frames 33, and they are all located inside the curing pool 1 along with the tray 31. Thus, when the brick stack enters the curing pool 1 along with the cage 12, it can be limited and protected from four directions.

[0042] Furthermore, refer to Figure 3 The upper end of the limiting rod 331 has a wedge-shaped structure, and the inclined side of the wedge abuts against the inner side of the guide groove 13. Simultaneously, the inner surface of the limiting rod 331 is on the same vertical line. During the downward movement of the brick stack carried by the cage 12, the guide groove 13, through its contact with the inclined surface of the limiting rod 331, pushes the limiting frame 33 closer to the side of the brick stack. This allows the limiting frame 33 to clamp and limit the brick stack from the side, preventing bricks from falling off due to water agitation. Furthermore, the inclined side of the limiting rod 331 exists only at the upper end, therefore the limiting rod... Only after the brick stack moves downward with the cage 12 for a certain distance can the guide groove 13 fully press and adhere the limiting rod 331 to the side of the brick stack, thus avoiding the problem of premature clamping and incomplete positioning. Conversely, when the cage 12 moves upward, the guide groove 13 will adhere to the lower outer side of the limiting rod 331 and move smoothly along it for a certain distance, so that the limiting protection of the brick stack will gradually loosen after the brick stack moves upward with the cage 12 for a certain distance, thus avoiding the problem of premature loosening and instability of the brick stack.

[0043] Among them, reference Figure 4 A spherical protrusion 34 is provided at the lower axis position of the tray 31, and the end of the spherical protrusion 34 is a hemispherical structure. A slot 35 is provided inside the spherical protrusion 34. By cooperating with the arc surface of the spherical groove 27, the spherical protrusion 34 can transform the perpendicular contact surface between the tray 31 and the receiving plate 21 into a smooth arc surface, making the rotational connection between the tray 31 and the receiving plate 21 smoother.

[0044] Among them, reference Figure 3 The reset component 32 includes an extension shaft 321 fixedly connected to the tray 31, a connecting shaft 322 inserted into the extension shaft 321, and the connecting shaft 322 fixedly connected to the limiting frame 33, and a spring 323 disposed between the connecting shaft 322 and the extension shaft 321. The spring 323 elastically supports the connecting shaft 322 to always push it outward, so that the connecting shaft 322 pushes the limiting rod 331 to always keep it in contact with the guide groove 13, and when the equipment is idle, the limiting frame 33 is stored in the guide groove 13.

[0045] In summary, during use, the brick stacks to be watered and cured are placed in the cage 12 using a forklift or other conveying structure. Under the control of the gantry crane 11, the cage 12 carries the brick stacks into the curing pool 1, immersing them in the curing pool 1. During this process, the stirring unit 2 stirs the water in the curing pool 1, keeping the water in the pool flowing. By immersing the brick stacks, they come into full contact with the water, completely avoiding the problem of insufficient watering. Furthermore, the immersion method greatly extends the contact time between the brick stacks and the water, ensuring that the bricks inside the stacks can effectively absorb water. At the same time, the stirring unit 2 inside the curing pool 1 stirs the water, causing the water in the pool to flow and turbulent. The flow of water can accelerate the contact and exchange speed between the water and the permeable bricks, thereby improving the water absorption efficiency and shortening the immersion time of the brick stacks.

[0046] During the process of the cage 12 carrying the brick stack into the curing pool 1, the guide groove 13 on the cage 12 will squeeze the limiting frame 33, so that the four sets of limiting frames 33 will move closer to the brick stack from all sides at the same time, thereby limiting and protecting the brick stack. This effectively prevents the bricks on the brick stack from being swept off by the water flow during the stirring unit 2 stirring the water flow, and ensures the stability of the brick stack during the immersion curing process.

[0047] Furthermore, based on the actual specifications of the brick stack, when the brick stack is small, refer to... Figure 7 At this time, the weight of the brick stack is relatively small. The relatively small weight of the brick stack cannot push the rectangular shaft 23 to move downward in a large way. As a result, the gear disk 25 meshes with the smaller diameter part of the drive gear 28. This makes the action of the gear disk 25 driving the rectangular shaft 23 to drive the stirring rod 22 to stir relatively slowly. This allows the water to flow through the brick stack more smoothly, ensuring that the water has enough time to penetrate into the brick and avoiding the water flowing too fast and not being able to penetrate fully.

[0048] When the brick stack is large, refer to... Figure 8 The tray 31 compresses the rectangular shaft 23 and moves it downwards by a large margin, so that the gear disk 25 meshes with the larger diameter part of the drive gear 28. At this time, the gear disk 25 drives the rectangular shaft 23 to drive the stirring rod 22 to stir faster, which makes the water flow faster. The faster water flow speed can provide greater pressure and power, allowing water to enter the pores of the permeable brick more quickly and accelerating the overall water absorption speed.

[0049] For large-sized brick stacks 5, a larger amplitude of water flow agitation allows water to penetrate to the center of the brick stack more quickly, avoiding insufficient water absorption in the center. For small-sized brick stacks 4, a smaller amplitude of water flow agitation ensures that water flows fully between the bricks, allowing each brick to fully absorb water, thereby improving the overall water absorption efficiency of the brick stack.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
