Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary calcination technology, specifically to an automatic discharge calcination device. Background Technology
[0002] Rotary calcination requires a rotary calcining kiln, which is mainly used to process lumpy, granular or powdery solid materials. Through rotation, the fuel is fully burned, and the heat is effectively transferred to the material, causing a series of physicochemical changes in the material, and finally forming finished clinker. Rotary kilns are widely used in many fields such as building materials, metallurgy, and chemical industry.
[0003] Existing calcination equipment uses a rotary method to uniformly heat the material during discharge, but some agglomeration occurs during discharge. After discharge, the raw material needs to be cooled and then screened, resulting in slow production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide an automatic discharge calcination device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic discharge calcination device, comprising a heating shell, a calcination tube rotatably connected inside the heating shell, a conveying plate fixedly connected inside the calcination tube, a discharge plate fixedly connected to one side of the heating shell near the bottom, a spring fixedly connected to the top of the discharge plate, a filter plate fixedly connected to the top of the spring, the filter plate being inclined, and a toggle block fixedly connected to the outside of the calcination tube near the filter plate.
[0006] Preferably, a limiting rod is fixedly connected to the top of the discharge plate, the limiting rod is disposed inside the spring, and the limiting rod is slidably connected inside the filter plate.
[0007] Preferably, the springs are arranged in a rectangular array of four groups, a limiting block is fixedly connected to the top of the filter plate, the limiting block abuts against the top of the filter plate, and the conveying plate is arranged in a spiral shape.
[0008] Preferably, a bearing is rotatably connected to the outside of the calcining tube, a positioning sleeve is rotatably connected to the outside of the bearing, a positioning rod is fixedly connected to the top of the positioning sleeve, and the positioning rod is fixedly connected to one side of the heating shell.
[0009] Preferably, the bottom of the positioning sleeve has a discharge port on the side away from the calcining tube, the discharge port is located above the filter plate, and a support block is fixedly connected to the bottom of the positioning sleeve on the side away from the calcining tube, and a sealing cover is slidably connected inside the support block.
[0010] Preferably, the bottom of the heating shell is fixedly connected to a support leg, and there are multiple sets of support legs arranged in a linear array at the bottom of the heating shell, and the support legs are arranged in an "H" shape.
[0011] Compared with the prior art, the beneficial effects of this utility model are: when the calcining tube inside the heating shell rotates, it drives the actuating block to move the filter plate, and the filter plate will press down the spring, causing the spring to extend and retract, thereby causing the filter plate to screen and screen the material transmitted from the calcining tube. Large pieces of material slide down the inclined surface, achieving the effect of rapid material screening. This solves the problem that the material needs to be screened again after the output of the single calcining tube, thus improving work efficiency. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution: such as Figure 1 - Figure 5The calcination device shown includes a heating shell 1, a calcination tube 2 rotatably connected inside the heating shell 1, a conveying plate 10 fixedly connected inside the calcination tube 2, a discharge plate 4 fixedly connected to one side of the heating shell 1 near the bottom, a spring 7 fixedly connected to the top of the discharge plate 4, a filter plate 6 fixedly connected to the top of the spring 7, the filter plate 6 being inclined, a toggle block 3 fixedly connected to the outside of the calcination tube 2 near the filter plate 6, a limit rod 5 fixedly connected to the top of the discharge plate 4, the limit rod 5 being located inside the spring 7, and the limit rod 5 being slidably connected inside the filter plate 6.
[0020] During operation, the material to be calcined is placed into one end of the calcination tube 2. The heating shell 1 heats the material inside the calcination tube 2, while the conveying plate 10 inside the calcination tube 2 transfers the material from one end to the other. When the material is discharged from the calcination tube 2, it falls onto the top of the filter plate 6. As the calcination tube 2 rotates, it also drives the actuating block 3 to move the filter plate 6. The filter plate 6 compresses the spring 7, allowing it to sway up and down. The limiting rod 5 restricts the position of the filter plate 6, thus limiting the sieving motion of the filter plate 6. Fine particles are screened out from below the filter plate 6 and discharged along the discharge plate 4, while larger particles fall along the inclined structure of the filter plate 6, achieving a rapid sieving and separation effect. This solves the problem of needing secondary sieving of the material after the discharge from the single calcination tube 2, improving work efficiency.
[0021] Please see Figure 1 - Figure 2 In the figure, there are four sets of springs 7 arranged in a rectangular array. The top of the filter plate 6 is fixedly connected to a limiting block 8, which abuts against the top of the filter plate 6. The conveying plate 10 is arranged in a spiral shape. The calcining tube 2 is rotatably connected to a bearing 11. The bearing 11 is rotatably connected to a positioning sleeve 12. The top of the positioning sleeve 12 is fixedly connected to a positioning rod 13, which is fixedly connected to one side of the heating shell 1.
[0022] During operation, the spring 7 can limit the sliding position of the filter plate 6, and the structure of the spring 7 ensures the direction of movement of the filter plate 6. The limiting block 8 can ensure that the filter plate 6 will not fall off the outside of the limiting rod 5 when it rebounds. The spiral structure of the conveying plate 10 can better transmit the material. When in use, the positioning sleeve 12 can also limit the discharge direction. The positioning sleeve 12 can fix the positioning rod 13, and the bearing 11 inside the positioning rod 13 ensures the smooth rotation of the calcining tube 2 and can also provide support force to the positioning rod 13, increasing the limiting effect of the discharge direction.
[0023] Please see Figure 3 - Figure 5In the figure, the bottom of the positioning sleeve 12 is provided with a discharge port 14 on the side away from the calcining tube 2. The discharge port 14 is located above the filter plate 6. The bottom of the positioning sleeve 12 is fixedly connected to a support block 15 on the side away from the calcining tube 2. A sealing cover 16 is slidably connected inside the support block 15. The bottom of the heating shell 1 is fixedly connected to a support leg 9. There are multiple sets of support legs 9 arranged in a linear array at the bottom of the heating shell 1. The support legs 9 are arranged in an "H" shape.
[0024] During operation, the material calcined in the calcining tube 2 can be transferred to the surface of the filter plate 6 through the discharge port 14 facing the filter plate 6 for screening, thus determining the discharge method. The support block 15 outside the positioning sleeve 12 can restrict the sealing cover 16. The material inside the calcining tube 2 can be observed by removing or installing the sealing cover 16. The support leg 9 can support the heating shell 1, increasing the observability of the inside of the calcining tube 2.
[0025] Working principle: The material to be calcined is placed into one end of the calcination tube 2. The heating shell 1 heats the material inside the calcination tube 2, while the conveying plate 10 inside the calcination tube 2 transfers the material from one end to the other. When the material is discharged from the calcination tube 2, it falls onto the top of the filter plate 6. As the calcination tube 2 rotates, it also drives the actuating block 3 to move the filter plate 6. The filter plate 6 compresses the spring 7, allowing it to sway up and down. The limiting rod 5 restricts the position of the filter plate 6, thus limiting the sieving motion of the filter plate 6. Fine particles are sieved out from below the filter plate 6 and discharged along the discharge plate 4, while larger particles fall along the inclined structure of the filter plate 6, achieving a rapid sieving and separation effect. This solves the problem of needing secondary sieving of the material after the discharge from the calcination tube 2, improving work efficiency. The spring 7 restricts the sliding position of the filter plate 6, and the structure of the spring 7 ensures the stability of the filter plate 6. The movement direction is controlled by the limiting block 8, which ensures that the filter plate 6 will not fall off the limiting rod 5 when it rebounds. The spiral structure of the conveying plate 10 can better transmit the material. When in use, the discharge direction can be restricted by the positioning sleeve 12. The positioning sleeve 12 can fix the positioning rod 13, and the bearing 11 inside the positioning rod 13 ensures the smooth rotation of the calcining tube 2 and can also provide support force to the positioning rod 13, increasing the limiting effect of the discharge direction. The material calcined by the calcining tube 2 can be transferred to the surface of the filter plate 6 through the discharge port 14 facing the filter plate 6, thereby performing screening and determining the discharge method. The support block 15 outside the positioning sleeve 12 can restrict the sealing cover 16. The material inside the calcining tube 2 can be observed by removing or installing the sealing cover 16. The support leg 9 can support the heating shell 1, increasing the observation effect inside the calcining tube 2.
