Description

Technical Field

[0001] This invention relates to the field of refractory waste recycling technology, and more specifically to a refractory material crushing and recycling device. Background Technology

[0002] Refractory materials are a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material, under no load, resists high temperatures without softening or melting. However, the definition of refractoriness alone cannot fully describe refractory materials; 1580℃ is not absolute. Currently, it is defined as any material whose physicochemical properties allow it to be used in high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, and power industries, with the largest consumption in the metallurgical industry, accounting for 50%-60% of total production. Refractory materials are essential basic materials for ensuring the production operation and technological development of these industries, playing an irreplaceable role in the development of high-temperature industrial production. The large consumption of refractory materials inevitably generates a large amount of waste refractory materials. Recycling refractory waste not only protects the environment and reduces costs but also avoids the waste of refractory resources. Currently, refractory material crushing equipment is commonly used for crushing and recycling.

[0003] However, existing refractory crushing devices have technical problems: 1. They require human supervision to add waste materials in a timely manner, which increases labor costs and makes operation cumbersome; 2. The crushing effect is not ideal, and waste materials that are not crushed to a sufficient degree often remain in the crushing mechanism, resulting in an unsatisfactory crushing effect.

[0004] Therefore, providing a simple-to-operate refractory material crushing and recycling device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a refractory material crushing and recycling device that achieves semi-automatic feeding, reduces feeding frequency, simplifies operation, and reduces labor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A refractory material crushing and recycling device includes a crushing mechanism, a collecting trough, a transfer mechanism, a conveying mechanism, and a conveying drive mechanism. The crushing mechanism has an inlet and an outlet. The collecting trough is placed below the crushing mechanism. The transfer mechanism is located on one side of the crushing mechanism and corresponds to the outlet and the inlet of the collecting trough, respectively. The conveying mechanism is located on one side of the crushing mechanism and its output end corresponds to the inlet. The transfer mechanism is connected to the conveying mechanism via the conveying drive mechanism.

[0008] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0009] The crushing mechanism crushes the waste material, and the crushed waste material is discharged from the outlet. The discharged waste material enters the transfer mechanism and rotates under the action of gravity. The waste material enters the collection tank. At the same time, the conveying drive mechanism drives the conveying mechanism to rotate, sending the waste material on it into the crushing mechanism. This achieves semi-automatic feeding, reduces the feeding frequency, eliminates the need for constant worker supervision, simplifies operation, and reduces labor.

[0010] Furthermore, the crushing mechanism includes a crushing box, multiple support legs, a gearbox, a motor, and two double-toothed rollers. The crushing box is placed on the ground via the multiple support legs. The collection trough is located below the crushing box. The feed inlet is located at the top of the crushing box, and the discharge outlet is located at the bottom of one side of the crushing box. The gearbox is fixed to the top of the crushing box via a support plate. The gearbox contains two meshing first gears. The motor is mounted on the top of the gearbox, and its output shaft is fixedly connected to either of the first gears. The two double-toothed rollers are located inside the crushing box and are spaced apart. The top ends of the two double-toothed rollers are respectively fixedly connected to the two first gears.

[0011] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the two double-toothed rollers are vertically distributed, and the high extrusion pressure generated by the relative rotation of the two wear-resistant alloy double-toothed rollers is used to crush the material. After the material enters the gap between the two double-toothed rollers, it is subjected to the extrusion and shearing forces of the two double-toothed rollers rotating relative to each other. Under the extrusion, shearing and grinding, the material is crushed into the required particle size, and the material is crushed more thoroughly.

[0012] Furthermore, the crushing mechanism also includes a connecting plate and two second gears. The bottom ends of the two double-toothed rollers are rotatably connected to the connecting plate, and the connecting plate is fixedly connected to the inner wall of the crushing box. The two second gears are respectively installed at the bottom ends of the two double-toothed rollers, and the two second gears are meshed together.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is to increase the structural stability of the crushing mechanism.

[0014] Furthermore, the transfer mechanism includes two base plates, a fixed shaft, a connecting frame, and multiple trays. The two base plates are placed vertically on the ground and are symmetrically distributed. The two ends of the fixed shaft are rotatably connected to the two base plates respectively. The connecting frame is fitted and fixed on the fixed shaft. The multiple trays are fixed between the two side plates of the connecting frame and are evenly distributed along the circumference. As the mechanism rotates, the trays correspond to the positions of the discharge port and the inlet of the collection trough.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are that waste material from the discharge port enters the pallet, and the connecting frame is rotated under the action of gravity, so that the waste material on the pallet is transferred to the collection tank.

[0016] Furthermore, the transfer mechanism also includes a fixed block, two telescopic rods, and two springs. The fixed block is fixed to the middle of the fixed shaft. Multiple clamping plates evenly distributed circumferentially are fixed to the inner side of each side plate. The two telescopic rods are located on both sides of the fixed block, and one end of each telescopic rod is fixed to the fixed block. The other end of each telescopic rod is fixed with a clamping block, which is fan-shaped and corresponds to the clamping plate. The two springs are respectively sleeved on the two telescopic rods, and both ends of each spring abut against the fixed block and the clamping block, respectively.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that when the waste on the pallet is collected to a certain extent, the weight of the waste causes the connecting frame to be subjected to a rotational force until the connecting frame drives the pallet to abut against the block and is misaligned with the block. At this time, the connecting frame and the pallet rotate, the pallet tilts, so that the waste can enter the collection trough. At the same time, the block is reset under the action of the spring and abuts against the adjacent pallet, so that the pallet corresponding to it stays at the discharge port position.

[0018] Furthermore, the conveying mechanism includes a support frame, a mounting frame, two idlers, and a conveyor belt. The support frame is placed on the ground; the mounting frame is fixed to the top of the support frame; the two idlers are respectively installed on both sides of the mounting frame; the conveyor belt is wound around the two idlers; and the output end of the conveyor belt corresponds to the position of the inlet.

[0019] Furthermore, the refractory material crushing and recycling device also includes a discharge chute, which is fixed to the top of the support frame by a support platform and located above the conveyor belt.

[0020] Furthermore, the conveying drive mechanism includes a fixed frame, two limiting blocks, two traction drive assemblies, and a connecting shaft. The fixed frame is vertically fixed to the mounting frame; the two limiting blocks are respectively fixed to the two bottom ends of the fixed frame; each traction drive assembly includes a ratchet, a rotating rod, a connecting rod, a pawl, a torsion spring, a pull rod, a stop rod, and a return spring; the two ratchets are respectively fixed to both ends of the idler roller located at the output end; the rotating rod is connected to the ratchet via a first shaft, and both ends of the first shaft are respectively fixedly connected to the rotating rod and the ratchet; the top end of the connecting rod is rotatably connected to the rotating rod via a second shaft. The pawl is rotatably connected to the second shaft and engages with the ratchet; the torsion spring is sleeved on the second shaft, and the two torsion arms of the torsion spring abut against the pawl and the rotating rod respectively; the two ends of the connecting shaft are rotatably connected to the bottom ends of the two connecting rods respectively; the pull rod is sleeved on the connecting shaft and vertically passes through the limiting block; a guide plate is fixed on the outer side of the side plate, and the guide plate has a star-shaped groove; the stop rod is horizontally fixed to the extension end of the pull rod and is fitted into the star-shaped groove; the return spring is sleeved on the pull rod and is located between the connecting shaft and the limiting block.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the rotation of the connecting frame drives the conveyor belt to transport goods. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1-9 As shown in the figure, this invention discloses a refractory material crushing and recycling device, including a crushing mechanism 1, a collection tank 2, a transfer mechanism 3, a conveying mechanism 4, and a conveying drive mechanism 5. The crushing mechanism 1 has an inlet 111 and an outlet 112; the collection tank 2 is placed below the crushing mechanism 1; the transfer mechanism 3 is located on one side of the crushing mechanism 1 and corresponds to the outlet 112 and the inlet of the collection tank 2, respectively; the conveying mechanism 4 is located on one side of the crushing mechanism 1 and its output end corresponds to the inlet 111; the transfer mechanism 3 is connected to the conveying mechanism 4 via the conveying drive mechanism 5. The crushing mechanism 1 crushes the waste material, and the crushed waste material is discharged from the outlet 112. The discharged waste material enters the transfer mechanism 3, rotates under gravity, and enters the collection tank 2. Simultaneously, the conveying drive mechanism 5 drives the conveying mechanism 4 to rotate, feeding the waste material onto the crushing mechanism 1, achieving semi-automatic feeding, reducing the feeding frequency, eliminating the need for constant worker supervision, simplifying operation, and reducing labor costs.

[0034] Specifically, the crushing mechanism 1 includes a crushing box 11, multiple support legs 12, a gearbox 13, a motor 14, and two double-toothed rollers 15. The crushing box 11 is placed on the ground by the multiple support legs 12. The collection trough 2 is located below the crushing box 11. The feed inlet 111 is located at the top of the crushing box 11, and the discharge outlet 112 is located at the bottom of one side of the crushing box 11. The gearbox 13 is fixed to the top of the crushing box 11 by a support plate. The gearbox 13 has two meshing first gears 131 inside. The motor 14 is installed on the top of the gearbox 13, and its output shaft is fixedly connected to either of the first gears 131. The two double-toothed rollers 15 are located inside the crushing box 11 and are spaced apart. The top ends of the two double-toothed rollers 15 are fixedly connected to the two first gears 131 respectively. The motor 14 drives one of the double-toothed rollers 15 to rotate through the first gear 131 connected to it, and drives the other double-toothed roller 15 to rotate through the meshing of the two first gears 131. The two double-toothed rollers 15 rotate and crush the waste material in the crushing box 11.

[0035] To further optimize the technical solution of the present invention, the crushing mechanism 1 also includes a connecting plate 16 and two second gears 17. The bottom ends of the two double-toothed rollers 15 pass through the connecting plate 16 and are rotatably connected thereto. The connecting plate 16 is fixedly connected to the inner wall of the crushing box 11. The two second gears 17 are respectively installed at the bottom ends of the two double-toothed rollers 15 and are meshed together, thereby increasing the structural stability of the crushing mechanism 1.

[0036] Specifically, the transfer mechanism 3 includes two base plates 31, a fixed shaft 32, a connecting frame 33, and multiple pallets 34. The two base plates 31 are placed vertically on the ground and are symmetrically distributed. The two ends of the fixed shaft 32 are rotatably connected to the two base plates 31 respectively. The connecting frame 33 is fitted and fixed on the fixed shaft 32. The multiple pallets 34 are fixed between the two side plates of the connecting frame 33 and are evenly distributed along the circumference. As the mechanism rotates, the pallets 34 correspond to the positions of the discharge port 112 and the inlet of the collection trough 2 respectively.

[0037] To further optimize the technical solution of the present invention, the transfer mechanism 3 also includes a fixed block 35, two telescopic rods 36, and two springs 37. The fixed block 35 is fixed to the middle of the fixed shaft 32; multiple clamping plates 38 evenly distributed circumferentially are fixed to the inner side of each side plate; the two telescopic rods 36 are respectively located on both sides of the fixed block 35, and one end of each telescopic rod 36 is fixed to the fixed block 35, and the other end of each telescopic rod 36 is fixed with a clamping block 39, which is fan-shaped and corresponds to the clamping plate 38; the two springs 37 are respectively sleeved on the two telescopic rods 36. On rod 36, and at both ends of each spring 37, abutting against fixed block 35 and locking block 39 respectively, when the waste on tray 34 is collected to a certain extent, the weight of the waste causes the connecting frame 33 to be subjected to rotational force until the connecting frame 33 drives the locking plate 38 to abut against the locking block 39 and is offset from the locking block 39. At this time, the connecting frame 33 and tray 34 rotate, and tray 34 tilts, so that the waste can enter the collection trough 2. At the same time, the locking block 39 is reset under the action of spring 37 and abuts against the adjacent locking plate 38, so that the corresponding tray 34 stays at the discharge port 112 position.

[0038] Specifically, the conveying mechanism 4 includes a support frame 41, a mounting frame 42, two idlers 43, and a conveyor belt 44.

[0039] Specifically, a refractory material crushing and recycling device also includes a discharge chute 6, which is fixed to the top of the support frame 41 by a support platform 7 and located above the conveyor belt 44.

[0040] Specifically, the conveying drive mechanism 5 includes a fixed frame 51, two limiting blocks 52, two traction drive components 53, and a connecting shaft 54. The fixed frame 51 is vertically fixed on the mounting frame 42; the two limiting blocks 52 are respectively fixed to the two bottom ends of the fixed frame 51; each traction drive component 53 includes a ratchet 531, a rotating rod 532, a connecting rod 533, a pawl 534, a torsion spring 535, a pull rod 536, a stop rod 537, and a return spring 538. The two ratchet wheels 531 are respectively fixed to both ends of the idler roller 43 located at the output end; the rotating rod 532 is connected to the ratchet wheel 531 through a first shaft, and both ends of the first shaft are fixedly connected to the rotating rod 532 and the ratchet wheel 531 respectively; the top end of the connecting rod 533 is rotatably connected to the rotating rod 532 through a second shaft, and the pawl 534 is rotatably connected to the second shaft. The ratchet 534 engages with the ratchet 531 to ensure greater stability when the crushing operation stops. The pawl 534 engages with the ratchet 531 to prevent the pallet from wobbling when the operation stops. The torsion spring 535 is fitted onto the second shaft, and the two torsion arms of the torsion spring 535 abut against the pawl 534 and the rotating rod 532 respectively, which can prevent the connecting rod 533 and the rotating rod 532 from wobbling, while maintaining a safe distance from the pawl 534. The two ends of the connecting shaft 54 ​​are rotatably connected to the bottom ends of the two connecting rods 533 respectively.

The stop rod 537 is horizontally fixed to the extension end of the pull rod 536 and is fitted into the star-shaped groove. The return spring 538 is fitted onto the pull rod 536 and is located between the connecting shaft 54 ​​and the limiting block 52.

[0041] Working principle of the invention:

[0042] First, waste material is placed into both the feeding trough 6 and the crushing box 11. The motor 14 is started, driving the first gear 131 connected to it to rotate. The double-toothed roller 15, fixedly connected to the first gear 131, rotates accordingly. Through the meshing of the two first gears 131, it drives the other double-toothed roller 15 to rotate. The two double-toothed rollers 15 rotate and crush the waste material in the crushing box 11. The crushed waste material enters the lower half of the crushing box 11 and, under the action of the double-toothed rollers 15, is discharged from the discharge port 112. The discharged waste material falls onto the pallet 34. When the waste material on the pallet 34 reaches a certain level, the weight of the waste material causes the connecting frame 33 to be subjected to a rotational force until the connecting frame 33 drives the clamping plate 38 to abut against the clamping block 39 and is displaced from the clamping block 38. At this time, the connecting frame 33 and the pallet 34 rotate, causing the pallet 34 to tilt, thus allowing the waste material to enter the collecting trough 2. Simultaneously, the clamping block 39 is reset under the action of the spring 37. The connecting frame 33 rotates while simultaneously driving the guide plate 55 to rotate. Under the action of the stop rod 537, the guide plate 55 pulls the pull rod 536 downward. The pull rod 536 drives one end of the connecting rod 533 downward through the connecting shaft 54. The connecting rod 533 drives the rotating rod 532 to rotate, thereby driving the first shaft to rotate and driving the ratchet 531 to rotate. The ratchet 531 drives the roller 43 to rotate, causing the conveyor belt 44 to rotate, thus sending the waste into the crushing box 11. The pawl 534 moves back and forth with the rotation of the ratchet 531. When the stop rod 537 is misaligned with the guide plate 55, the elastic force of the return spring 538 drives the pull rod 536 to rise and reset, thereby causing the rotating rod 532 to reverse. The rotating rod 532 drives the pawl 534 to reverse and, under the action of the torsion spring 535, misaligns it with the ratchet 531, thus preventing the conveyor belt 44 from rotating in the opposite direction.
