Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lime production technology, and more specifically, it relates to a feeding device. Background Technology
[0002] Lime, as a traditional and widely used inorganic cementing material, plays a crucial role in many fields such as construction, metallurgy, and chemical industry. Its main component is calcium oxide, which is usually produced by calcining and decomposing carbonate rocks such as limestone and dolomite in a lime kiln at high temperatures.
[0003] Currently, lime kilns are usually equipped with a special feeding device (such as a screw conveyor or vibrating feeder) at the bottom. After the lime is calcined, the feeding device is used to output the lime and transport it from the bottom of the kiln to the subsequent processing steps.
[0004] The inventors discovered that during the high-temperature calcination stage of lime production, due to factors such as the composition and particle size of the stone, as well as the calcination temperature and time, some of the stone may sinter after calcination. The size of the sintered lime blocks often exceeds the size requirements of the feeding device, causing blockage inside the feeding device, which in turn affects the continuity of lime output, resulting in a significant reduction in production efficiency, and may also cause equipment failure, increasing equipment maintenance costs and workload. Utility Model Content
[0005] The purpose of this application is to provide a feeding device to solve the technical problem in existing lime production where large lumps of lime sintered into lime easily cause blockages inside the feeding device.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A feeding device is provided, comprising: A cylindrical body is used to be installed below the ash discharge port of a lime kiln, and the cylindrical body adopts a top-opening structure so that materials can fall into the interior of the cylindrical body; A pallet, disposed within the cylinder, is used to receive material falling into the cylinder; the pallet is adapted to reciprocate along a straight line, and the pallet is driven by a linear drive mechanism; and Two baffles are arranged side by side above the pallet along the straight line, and each baffle has a gap between itself and the upper side of the pallet to form a first discharge port for material to pass through. When the material on the pallet moves back and forth along the straight direction with the pallet, the lumps of material will come into contact with the baffle and break; the broken material is suitable to be discharged through the first discharge port to the lower side of the pallet.
[0007] In one possible implementation, the stop member includes: A crossbeam is fixedly installed inside the cylinder and located above the support plate; and Multiple toothed bars are spaced apart on the crossbeam along its length; The lower ends of the plurality of toothed bars and the upper side of the pallet form the first discharge port; Furthermore, a second discharge port is formed between two adjacent toothed bars. The second discharge port is used to allow materials in a crushed state to pass through, and can also restrict the passage of materials in clumps.
[0008] In one possible implementation, each of the toothed bars is slidably connected to the crossbeam to be adapted to move toward or away from the support plate; and each of the toothed bars and the crossbeam is provided with a locking structure, the locking structure comprising: Multiple limiting holes are formed on the toothed bar and spaced apart along the length of the toothed bar; each limiting hole extends radially through the toothed bar; and A limiting pin is slidably disposed on the crossbeam and is adapted to be inserted into any one of the limiting holes.
[0009] In one possible implementation, the lower end of each of the toothed bars has a conical structure.
[0010] In one possible implementation, the linear drive mechanism includes: A pull rod is slidably connected to the cylinder along the straight line direction; one end of the pull rod is connected to the support plate, and the other end is hinged to a connecting rod. A rotating wheel is rotatably mounted on the cylinder and is connected to a driving component; a lever is hinged to the rotating wheel and the lever is hinged to the connecting rod, so that when the rotating wheel rotates, the lever, in conjunction with the connecting rod, drives the pull rod to reciprocate along the linear direction.
[0011] In one possible implementation, the driving component includes: A worm gear, coaxially connected to one side of the rotating wheel; and A drive motor is fixedly mounted on the outside of the worm wheel, and its power output end is connected to a worm that meshes with the worm wheel.
[0012] In one possible implementation, the cylinder has a through hole extending along the straight line, and the pull rod is slidably inserted into the through hole; and a guide sleeve coaxially connected to the through hole is fixedly provided on the outer wall of the cylinder, and the inner peripheral wall of the guide sleeve is connected to the outer peripheral wall of the pull rod.
[0013] In one possible implementation, the upper side of the tray has a plurality of protruding ridges spaced apart along the straight line, and the length direction of each protruding ridge is perpendicular to the straight line direction.
[0014] In one possible implementation, a roller is rotatably connected to the pallet, the roller is in contact with the inner wall of the cylinder, and the rotation axis of the roller is perpendicular to the straight line direction.
[0015] In one possible implementation, each of the material stoppers has a guide plate on its upper side; the lower end of the guide plate is aligned with the adjacent sides of the two material stoppers, and the upper end of the guide plate is aligned with the edge of the cylinder, so that the material falling into the cylinder moves along the guide plate to between the two material stoppers.
[0016] In this embodiment, the material discharged from the lime kiln's ash discharge port falls into the cylinder from the top opening due to gravity and directly onto the upper surface of the pallet, where it is temporarily stored. A linear drive mechanism is activated, driving the pallet to reciprocate along a set linear direction, i.e., a "push-pull" cycle. As the pallet moves, the material on it moves synchronously. When large pieces of material move with the pallet to below the baffle, because the baffle is fixed above the pallet, the large pieces collide and are squeezed against it, similar to "shearing" or "crushing," thus being broken into smaller particles. The smaller particles, due to their reduced size, can fall from the upper side of the pallet to the lower side through the first discharge port between the baffle and the pallet, completing the discharge. Large pieces of material that are not completely crushed will move in the opposite direction with the pallet, repeating the "collision-crushing" process when passing the baffle again, until the particle size meets the requirements of the first discharge port and is discharged.
[0017] Compared with the prior art, the feeding device provided in this application embodiment features a reciprocating movement of the pallet combined with a fixed baffle design, which allows large pieces of material to be repeatedly crushed during multiple reciprocating motions, ensuring thorough crushing. By adjusting the gap between the baffle and the pallet, the particle size of the final discharged material can be flexibly controlled. The material crushing and discharge processes are both completed inside the enclosed cylinder, reducing dust overflow and improving the working environment of the lime kiln ash discharge process, thus meeting environmental protection requirements. The device can be adapted to the ash discharge volume and material hardness requirements of different lime kilns by adjusting the pallet moving speed, the number of baffles, or the gap size, making the equipment highly versatile.

Therefore, they should not be construed as limitations on this application.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0024] Please refer to the following: Figures 1 to 7 The feeding device provided in this application will now be described. The feeding device includes a cylinder 1, a support plate 2, and two baffles 4.
[0025] The cylinder 1 is installed below the ash discharge port of the lime kiln, and the cylinder 1 adopts an open top structure so that the material can fall freely into the cylinder 1; the cylinder 1 is sealed to the kiln body of the lime kiln to prevent dust from overflowing when the material is discharged, thus improving the environmental performance of the equipment.
[0026] The pallet 2 is installed inside the cylinder 1 to receive the material falling into the cylinder 1; the pallet 2 is adapted to reciprocate along a straight line, and the pallet 2 is connected to a linear drive mechanism 3.
[0027] Two baffles 4 are arranged side by side in a straight line above the pallet 2. Each baffle 4 has a gap with the upper side of the pallet 2 to form a first discharge port for material to pass through.
[0028] When the material on pallet 2 moves back and forth in a straight line along pallet 2, the lumps of material will come into contact with the baffle 4 and break; the broken material is suitable to be discharged through the first discharge port to the lower side of pallet 2.
[0029] The proposed solution utilizes the reciprocating motion of the pallet 2 and the fixed structure of the baffle 4, eliminating the need for additional crushing equipment, thus reducing costs and enabling continuous operation, thereby improving ash removal efficiency.
[0030] In this embodiment, the material discharged from the lime kiln's ash discharge port falls into the cylinder 1 from the top opening due to gravity, and directly onto the upper surface of the pallet 2, where it is temporarily stored. The linear drive mechanism 3 is activated, driving the pallet 2 to reciprocate along a set linear direction, i.e., a "push-pull" cycle. As the pallet 2 moves, the material on it moves synchronously with it. When large pieces of material move with the pallet 2 to below the baffle 4, because the baffle 4 is fixed above the pallet 2, the large pieces of material will collide and be squeezed with the baffle 4, similar to "shearing" or "compression crushing," thus being crushed into smaller particles. Due to the reduced size, the crushed small particles can fall from the upper side of the pallet 2 to the lower side of the pallet 2 through the first discharge port between the baffle 4 and the pallet 2, completing the discharge. Large pieces of material that are not completely crushed will move in the opposite direction with the pallet 2, repeating the "collision-crushing" process when passing the baffle 4 again, until the particle size meets the requirements of the first discharge port and is discharged.
[0031] Compared with the prior art, the feeding device provided in this application embodiment features a design where the pallet 2 reciprocates in conjunction with the fixed baffle 4, ensuring that large pieces of material are repeatedly crushed during multiple reciprocations, thus guaranteeing thorough crushing. By adjusting the gap between the baffle 4 and the pallet 2, the particle size of the final discharged material can be flexibly controlled. The material crushing and discharge processes are both completed inside the enclosed cylinder 1, reducing dust spillage, improving the working environment of the lime kiln ash discharge process, and meeting environmental protection requirements. The device can be adapted to the ash discharge volume and material hardness requirements of different lime kilns by adjusting the moving speed of the pallet 2, the number of baffles 4, or the gap size, making it highly versatile.
[0032] In some embodiments, the aforementioned baffle 4 can be adopted as follows: Figure 1 , Figures 3 to 6 The structure shown is described in the following document. Figure 1 , Figures 3 to 6 The stopper 4 includes a crossbeam 41 and multiple toothed bars 42.
[0033] The crossbeam 41 is fixedly installed inside the cylinder 1 and located on the upper side of the support plate 2; the crossbeam 41 can provide an installation location for multiple toothed bars 42; the multiple toothed bars 42 are spaced apart on the crossbeam 41 along its length.
[0034] The lower ends of multiple toothed bars 42 and the upper side of the pallet 2 form the first discharge port; the material moves with the pallet 2 to the area below the toothed bars 42; large pieces of material can be blocked by the toothed bars 42 and crushed between the toothed bars 42; the crushed medium-sized particles (smaller than the spacing between the toothed bars 42) are discharged from the second discharge port.
[0035] Furthermore, a second discharge port is formed between two adjacent toothed bars 42. The second discharge port is used to allow crushed materials to pass through and can also restrict the passage of lumpy materials. Finer particles (smaller than the gap between the lower end of the toothed bar 42 and the support plate 2) are discharged from the first discharge port.
[0036] By adopting the above technical solution, the multi-stage discharge port design (second discharge port + first discharge port) can accurately control the output particle size of lime; the toothed bar 42 interval structure increases the contact area between the material and the crushing surface, improves the crushing efficiency of lime blocks, and can prevent large pieces of material from being discharged directly, ensuring uniform feeding, and also preventing large pieces of material from clogging the lower discharge port of cylinder 1.
[0037] In some embodiments, the toothed rod 42 may be as follows: Figure 1 , Figure 4 , Figure 5 and Figure 6 The structure shown is described in the following document. Figure 1 , Figure 4 , Figure 5 and Figure 6 Each toothed bar 42 is slidably connected to the crossbeam 41 to be adapted to move toward or away from the support plate 2; and each toothed bar 42 is provided with a locking structure 5 between it and the crossbeam 41, the locking structure 5 including multiple limiting holes 51 and limiting pins 52.
[0038] Multiple limiting holes 51 are provided on the toothed bar 42 and are spaced apart along the length of the toothed bar 42; each limiting hole 51 is radially through the toothed bar 42.
[0039] The limiting pin 52 is slidably disposed on the crossbeam 41 and is suitable for insertion into any of the limiting holes 51.
[0040] The principle of adjusting the height of the toothed bar 42: The operator can loosen the limit pin 52, slide the toothed bar 42 to the target height, and then re-insert the limit pin 52 into the corresponding limit hole 51 to fix the toothed bar 42; after adjusting the height of the toothed bar 42, the gap size of the first discharge port changes, thereby controlling the particle size of the fine particles discharged, so that the equipment can adapt to the crushing particle size requirements of different materials.
[0041] By adopting the above technical solution, the height of the toothed bar 42 is adjustable, which can adapt to the crushing needs of different materials (such as different sizes of lime blocks); and only the limiting hole 51 and the limiting pin 52 are required, which makes the structure simple and the adjustment operation convenient; and after long-term use, the height of the toothed bar 42 can be adjusted to compensate for the height after wear, thereby improving the service life of the toothed bar 42.
[0042] In some embodiments, the toothed rod 42 may be as follows: Figures 4 to 6 The structure shown is described in the following document. Figures 4 to 6 Each toothed bar 42 has a conical structure at its lower end.
[0043] During discharge, the material moves with the pallet 2 to below the tip of the cone. The tip inserts into the weak part of the material, destroying its structure. The material disperses along the cone surface and can further collide and crush with the adjacent toothed bar 42. The lower end of the toothed bar 42 adopts a cone structure (tip facing down). When the material comes into contact with the toothed bar 42, the cone tip concentrates stress, making it easier to insert into the material and accelerate the crushing of the material. At the same time, the cone surface can guide the material to disperse to both sides, avoiding material accumulation.
[0044] By adopting the above technical solution, the conical tip of the toothed bar 42 can reduce crushing resistance and improve crushing efficiency; it can also reduce the contact area between the material and the toothed bar 42, reducing wear; and it can also disperse the material flow direction to avoid local material blockage.
[0045] In some embodiments, the linear drive mechanism 3 described above may employ, for example... Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The linear drive mechanism 3 includes a pull rod 31 and a rotating wheel 32.
[0046] The pull rod 31 is slidably connected to the cylinder 1 in a straight line; one end of the pull rod 31 is connected to the support plate 2, and the other end is hinged to the connecting rod 33; the rotating wheel 32 is rotatably mounted on the cylinder 1 and is connected to the driving component 6; a lever is hinged on the rotating wheel 32 and the lever is hinged to the connecting rod 33 so that when the rotating wheel 32 rotates, the lever and the connecting rod 33 drive the pull rod 31 to reciprocate in a straight line.
[0047] Working principle: The driving component 6 drives the rotating wheel 32 to rotate. The lever on the rotating wheel 32 pulls the pull rod 31 through the connecting rod 33, converting the rotational motion into the linear reciprocating motion of the pull rod 31. The pull rod 31 is connected to the support plate 2, thereby driving the support plate 2 to move reciprocally in a straight line.
[0048] The above structure can smoothly convert rotary motion into linear motion with low transmission impact, compact structure, and small space occupation; the movement stroke of the pallet 2 can be flexibly controlled by adjusting the radius of the rotating wheel 32 or the length of the connecting rod 33.
[0049] In some embodiments, the driving member 6 described above may be as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The driving component 6 includes a worm gear 61 and a drive motor 62.
[0050] The worm gear 61 is coaxially connected to one side of the rotating wheel 32; the drive motor 62 is fixedly mounted on the outside of the worm gear 61, and its power output end is connected to the worm 63 that meshes with the worm gear 61.
[0051] The drive motor 62 outputs power to the worm wheel 61 through the worm 63 (the worm wheel 61 is coaxial with the rotating wheel 32). Utilizing the speed reduction and torque increase characteristics of the worm wheel 61 and worm 63, the rotating wheel 32 is driven to rotate at low speed and with high torque, thereby driving the support plate 2 to move back and forth. The worm wheel 61 and worm 63 transmission has self-locking properties (the worm 63 can drive the worm wheel 61, but the worm wheel 61 cannot drive the worm 63 in the reverse direction), preventing accidental reverse rotation.
[0052] By adopting the above structure, the worm gear 61 and worm 63 transmission has a large reduction ratio, which is suitable for heavy-load scenarios in lime kilns; and the self-locking characteristics of the worm gear 61 and worm 63 improve safety, so that the pallet 2 will not slip due to the weight of the material when the machine stops; and the transmission is smooth and the noise is low.
[0053] In some embodiments, the cylinder 1 may be adopted as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The cylinder 1 has a through hole running in a straight line, and the pull rod 31 is slidably inserted into the through hole; and a guide sleeve 11 coaxially connected to the through hole is fixedly installed on the outer wall of the cylinder 1, and the inner peripheral wall of the guide sleeve 11 is connected to the outer peripheral wall of the pull rod 31.
[0054] The through hole on the cylinder 1 is coaxial with the guide sleeve 11 on the outer wall. The pull rod 31 passes through the through hole and the guide sleeve 11. The inner peripheral wall of the guide sleeve 11 contacts the outer peripheral wall of the pull rod 31, providing linear motion guidance for the pull rod 31 and reducing the swaying or deviation of the pull rod 31.
[0055] The guide sleeve 11 can reduce the friction between the pull rod 31 and the cylinder 1, avoid direct wear on the cylinder 1, and extend the service life of the cylinder 1; the guide sleeve 11 can also improve the moving accuracy of the pallet 2 and ensure the stability of the gap between the pallet 2 and the stop 4.
[0056] In some embodiments, the tray 2 described above can be as follows: Figure 3 , Figure 4 , Figure 5 and Figure 7 The structure shown is described in the following document. Figure 3 , Figure 4 , Figure 5 and Figure 7 The upper side of the tray 2 has a plurality of protruding ribs 21 spaced apart along a straight line, and the length direction of each protruding rib 21 is perpendicular to the straight line direction.
[0057] The length direction of the protruding rib 21 on the pallet 2 is perpendicular to the direction of movement, which increases the contact friction between the pallet 2 and the material, prevents the material from sliding on the pallet 2 due to inertia, and ensures that the material moves synchronously with the pallet 2 and fully collides and breaks with the baffle 4.
[0058] The protruding ridge 21 can enhance the bonding force between the material and the pallet 2, and avoid insufficient crushing caused by material slippage; the protruding ridge 21 can also help disperse the material and avoid local accumulation of material; and the structure of the protruding ridge 21 is simple, and only the protruding ridge 21 needs to be processed on the pallet 2, which is low cost.
[0059] In some embodiments, the tray 2 described above can be as follows: Figure 5 and Figure 7 The structure shown is described in the following document. Figure 5 and Figure 7 A roller 22 is rotatably connected to the pallet 2. The roller 22 is in contact with the inner wall of the cylinder 1, and the rotation axis of the roller 22 is perpendicular to the straight line direction.
[0060] The roller 22, which is rotatably connected to the lower side of the pallet 2, contacts the inner wall of the cylinder 1, converting the sliding friction between the pallet 2 and the cylinder 1 into rolling friction, thus reducing the moving resistance of the pallet 2. The rolling friction resistance of the rolling connection is small, which reduces the energy consumption of the drive mechanism and can reduce the wear between the pallet 2 and the cylinder 1, extending the service life of the cylinder 1. The support of the roller 22 can ensure the stability of the pallet 2 when it moves and prevent the pallet 2 from getting stuck.
[0061] In some embodiments, the aforementioned baffle 4 can be adopted as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 1 , Figure 3 , Figure 4 and Figure 5 Each baffle 4 has a guide plate 7 on its upper side; the lower end of the guide plate 7 is aligned with the adjacent sides of the two baffles 4, and the upper end of the guide plate 7 is aligned with the edge of the cylinder 1, so that the material falling into the cylinder 1 moves along the guide plate 7 to the space between the two baffles 4.
[0062] The upper end of the guide plate 7 is connected to the edge of the cylinder 1, and the lower end is aligned with the adjacent sides of the two baffles 4. It guides the material falling into the cylinder 1 to slide along the guide plate 7 into the area between the two baffles 4, ensuring that the material is concentrated in the crushing area and avoiding it from scattering into the non-crushing area.
[0063] The guide plate 7 can concentrate the flow of materials and improve the material utilization rate of the crushing area; the guide plate 7 can prevent materials from scattering to the edge of the pallet 2 and reduce the discharge of uncrushed materials; and it can optimize the material distribution and improve the overall crushing efficiency.
[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
