Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, and more specifically, to a calcination device. Background Technology

[0002] The dolomite calcination device is a special rotary kiln developed to meet the calcination characteristics and process requirements of dolomite, and uniform heating of dolomite during calcination is particularly crucial.

[0003] A search revealed an existing patent (publication number: CN218884630U) that discloses a cobalt carbonate calcination device, including a cobalt carbonate rotary kiln. A rotary kiln support platform is located on one side of the kiln, a first rotary kiln support is located on the side of the support platform closest to the kiln, and a second rotary kiln support is located on the side of the kiln closest to the first support. This cobalt carbonate calcination device utilizes a cobalt carbonate transmission pipe, a cobalt carbonate buffer pipe, a cobalt carbonate transmission trough, a first cobalt carbonate limiting plate, and a second cobalt carbonate limiting plate. The cobalt carbonate transmission trough inside the transmission pipe is equipped with the first and second cobalt carbonate limiting plates, which divide the transmission trough into four channels. This prevents the cobalt carbonate to be processed from accumulating at the bends of the transmission pipe during transport, thus preventing blockages and achieving the function of preventing clogging during the feed of the cobalt carbonate calcination device. In the process of developing this application, the inventors discovered the following problems with the existing technology:

[0004] The existing heating methods of calcination equipment cannot achieve uniform heating of the calcined material. If uniform heating is not achieved, it will affect the quality of calcination. In addition, the tilt angle of the existing rotary kiln cannot be adjusted. During calcination, the rotation angle cannot be adjusted according to the characteristics of the heated material. Furthermore, an inappropriate tilt angle will also lead to uneven heating of the calcined product.

[0005] Therefore, a calcination apparatus is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a calcination apparatus to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a calcination device, comprising a calcination furnace body, wherein the calcination furnace body is a hollow cylinder, and a heating inner cylinder is connected to the center of the calcination furnace body; a support and adjustment connecting box is sleeved on the outer side of one end of the calcination furnace body, and a heating box is connected to the end of the calcination furnace body near the support and adjustment connecting box.

[0008] The calcining furnace body has a supporting base plate at its bottom, and a supporting base is connected between the supporting base plate and the calcining furnace body. An adjusting base is located below the supporting base plate, and an angle adjusting mechanism is connected to the top of the adjusting base. An adjusting cylinder is located on one side of the angle adjusting mechanism.

[0009] Preferably, the top of the calcining furnace body is provided with a feeding port, and the top of the feeding port is connected with a sealing cover. The bottom of the end of the calcining furnace body away from the heating box is connected with a material guide plate, and the inner side of the support base is provided with multiple sets of auxiliary rollers arranged in an arc array.

[0010] Preferably, a rotary drive motor is provided below the heating box, and the rotary drive motor and the support base plate are respectively connected to the two sides of the support adjustment connection box. Two sets of rotating connecting blocks are connected to the top of the adjustment base, and the rotating connecting blocks are connected to the bottom of the support adjustment connection box through a rotating shaft.

[0011] Preferably, a drive wheel is connected to the output shaft of the rotary drive motor, and the drive wheel is connected to the calcining furnace body through a transmission belt in the support adjustment connection box. A transmission gear ring is provided on the inner side of one end of the calcining furnace body.

[0012] Preferably, a rotating gear ring is provided on the outer side of one end of the heating inner cylinder near the support adjustment connecting box, and two sets of mutually symmetrical transmission gears are connected between the transmission gear ring and the rotating gear ring, and the two sets of transmission gears mesh evenly with the transmission gear ring and the rotating gear ring.

[0013] Preferably, a telescopic push block is connected to the output shaft of the adjusting cylinder, adjusting grooves are provided on both sides of the angle adjusting housing, and four sets of symmetrical connecting rods are connected between the angle adjusting housing and the support base plate through a rotating shaft, and the telescopic push block passes through the adjusting groove and is connected to the rotating shaft at one end of the connecting rod.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the prior art, this calcination device sets up two sets of heating equipment and sets up equipment with the same heating time and temperature inside and outside, so that the heating temperature on both sides of the calcined material is always the same during the tumbling heating process. The main body of the calcination furnace and the inner heating cylinder are heated by the heating box, thereby ensuring the synchronous heating and the same temperature of the main body of the calcination furnace and the inner heating cylinder.

[0016] 2. Compared with the prior art, this calcination device achieves more uniform heating of the calcined material through a double-flipping action. A rotary drive motor drives a drive wheel to rotate, which in turn drives the main body of the calcination furnace to rotate via a transmission belt. During the rotation of the main body of the calcination furnace, the internal transmission gear ring rotates. The transmission gear ring, through two sets of transmission gears, drives the rotating gear ring and the heating inner cylinder connected to it to rotate, thereby achieving synchronous rotation of the heating inner cylinder and the main body of the calcination furnace. The calcined material undergoes a tumbling action once when it comes into contact with the inner wall of the calcination furnace body, and a second tumbling action when it comes into contact with the outer wall of the heating inner cylinder. This double tumbling action achieves more uniform heating.

[0017] 3. Compared with the prior art, this calcination device can adjust the tilt angle of the calcination furnace, thereby meeting the calcination needs of more different calcination materials. The tilt angle of the calcination furnace body is adjusted according to the characteristics of the heating material. The telescopic push block is driven by the adjusting cylinder to move telescopically along the direction of the adjusting slide. During the movement of the telescopic push block, one end of the connecting rod slides within the adjusting slide. During the movement of the connecting rod, one end of the supporting base plate rotates. During the rotation, the supporting adjusting connecting box rotates on the adjusting base through the rotating connecting block, thereby realizing the adjustment of the tilt angle of the calcination furnace body.

Detailed Implementation

[0024] 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.

[0025] As attached Figures 1 to 5 The calcination apparatus shown includes a calcination furnace body 1, which is a hollow cylinder. A heating inner cylinder 13 is connected to the center of the calcination furnace body 1. A support and adjustment connecting box 2 is sleeved on the outer side of one end of the calcination furnace body 1, and a heating box 3 is connected to the end of the calcination furnace body 1 near the support and adjustment connecting box 2.

[0026] The calcining furnace body 1 is provided with a supporting base plate 21 below it, and a supporting base 22 is connected between the supporting base plate 21 and the calcining furnace body 1. An adjusting base 5 is provided below the supporting base plate 21, and an angle adjusting mechanism 53 is connected to the top of the adjusting base 5. An adjusting cylinder 6 is provided on one side of the angle adjusting mechanism 53. The calcining furnace body 1 and the heating inner cylinder 13 are both heated by the heating mechanism 3, thereby ensuring that the heating of the calcining furnace body 1 and the heating inner cylinder 13 is synchronized and the temperature is the same. The heating mechanism 3 can be electrically heated by adding electric heating tubes to the calcining furnace body 1 and the heating inner cylinder 13, or it can be heated by combustion and then heat conduction. The specific heating method of the calcining furnace is a mature existing technology. The specific heating and heat transfer methods will not be described in detail here. The calcining furnace body 1 is connected and fixed by the supporting adjusting connection box 2 and the supporting base plate 21. The rotation angle of the calcining furnace body 1 and the supporting base plate 21 is controlled by the adjusting cylinder 6 on the adjusting base 5 through the angle adjusting mechanism 53.

[0027] In a preferred embodiment, the top of the calcining furnace body 1 is provided with a feeding port 11, and the top of the feeding port 11 is connected to a sealing cover 111. The bottom of the end of the calcining furnace body 1 away from the heating box 3 is connected to a material guide plate 12. Multiple sets of auxiliary rollers 221 arranged in an arc array are provided on the inner side of the support base 22. The material to be calcined can be added into the calcining furnace body 1 through the feeding port 11, and after the addition is completed, the sealing work can be carried out by the sealing cover 111, so as to prevent the calcined material inside the calcining furnace body 1 from falling off during the rotation of the calcining furnace body 1. The calcining furnace body 1 is supported and connected to the support base plate 21 by the support base 22, and the calcining furnace body 1 rotates on the support base plate 21 through the auxiliary rollers 221 during the rotation. After the calcination is completed, the calcined material inside the calcining furnace body 1 can be poured out through the material guide plate 12.

[0028] In a preferred embodiment, a rotary drive motor 4 is installed below the heating chamber 3, and the rotary drive motor 4 and the supporting base plate 21 are respectively connected to the two sides of the supporting adjustment connecting box 2. Two sets of rotating connecting blocks 51 are connected to the top of the adjusting base 5, and the rotating connecting blocks 51 are connected to the bottom of the supporting adjustment connecting box 2 through a rotating shaft. The rotation of the calcining furnace body 1 and the heating inner cylinder 13 can be driven by the rotary drive motor 4. In contrast, traditional calcining furnaces can only rotate and tumble the calcining material inside by rotating the rotary kiln, thereby completing a relatively uniform calcination. However, during the calcination process, the side of the calcining material that contacts the inner wall of the rotary kiln... The heating temperature on the side that is far away is relatively high, while the temperature on the side that is far away is relatively low. Moreover, during the tumbling process, it is impossible to ensure that the heat received by both sides is consistent, which will lead to uneven heating of the calcined material. This application solves this problem by setting up equipment with the same heating time and temperature on both the inside and outside, so that the heating temperature received by both sides of the calcined material is always the same during the tumbling heating process. The support adjustment connection box 2 can be rotated on the adjustment base 5 by rotating the connection block 51, thereby driving the calcining furnace body 1 connected to it to adjust the tilt angle. The speed of calcining movement can be controlled by adjusting the tilt angle, and rapid tilting can be achieved by large tilt adjustment when feeding.

[0029] In a preferred embodiment, a drive wheel 41 is connected to the output shaft of the rotary drive motor 4, and the drive wheel 41 is connected to the calcining furnace body 1 through a transmission belt in the support adjustment connection box 2. A transmission gear ring 14 is provided on the inner side of one end of the calcining furnace body 1. The rotary drive motor 4 drives the drive wheel 41 to rotate, and the drive wheel 41 drives the calcining furnace body 1 to rotate through the transmission belt. During the rotation of the calcining furnace body 1, the transmission gear ring 14 inside it rotates.

[0030] In a preferred embodiment, a rotating gear ring 131 is provided on the outer side of the heating inner cylinder 13 near the supporting adjustment connecting box 2, and two sets of mutually symmetrical transmission gears 15 are connected between the transmission gear ring 14 and the rotating gear ring 131, and the two sets of transmission gears 15 uniformly drive the transmission gear ring 14 and the rotating gear ring 131 to mesh; during the rotation of the transmission gear ring 14, the rotating gear ring 131 and the heating inner cylinder 13 connected thereto are driven to rotate through the two sets of transmission gears 15, thereby realizing the synchronous rotation of the heating inner cylinder 13 and the calcining furnace body 1, and the calcining material undergoes a rolling action once when it comes into contact with the inner wall of the calcining furnace body 1, and the lifted calcining material undergoes another rolling action when it comes into contact with the outer wall of the heating inner cylinder 13, thereby achieving more uniform heating through the two rolling actions.

[0031] In a preferred embodiment, a telescopic push block 61 is connected to the output shaft of the adjusting cylinder 6. Adjusting grooves 531 are provided on both sides of the angle adjusting housing 53. Four sets of symmetrical connecting rods 52 are connected between the angle adjusting housing 53 and the supporting base plate 21 through a rotating shaft. The telescopic push block 61 passes through the adjusting groove 531 and is connected to the rotating shaft at one end of the connecting rod 52. The adjusting cylinder 6 drives the telescopic push block 61 to move telescopically along the direction of the adjusting groove 531. During the movement, the telescopic push block 61 drives one end of the connecting rod 52 to slide within the adjusting groove 531. During the movement, the connecting rod 52 drives one end of the supporting base plate 21 to rotate. During the rotation, the supporting adjusting connecting box 2 rotates on the adjusting base 5 through the rotating connecting block 51, thereby realizing the adjustment of the tilt angle of the calcining furnace body 1.

[0032] The working process of this utility model is as follows: First, the tilt angle of the calcining furnace body 1 can be adjusted according to the characteristics of the heating material. The telescopic push block 61 is driven by the adjusting cylinder 6 to move telescopically along the direction of the adjusting slide 531. During the movement, the telescopic push block 61 drives one end of the connecting rod 52 to slide within the adjusting slide 531. During the movement, the connecting rod 52 drives one end of the supporting base plate 21 to rotate. During the rotation, the supporting adjusting connecting box 2 rotates on the adjusting base 5 through the rotating connecting block 51, thereby realizing the adjustment of the tilt angle of the calcining furnace body 1.

[0033] Then, the calcining furnace body 1 and the heating inner cylinder 13 are preheated by the heating box 3. When the temperature is reached, the material to be calcined is added into the calcining furnace body 1 through the feeding port 11. After the addition is completed, the sealing work can be carried out by the sealing cover 111. At this time, the rotating drive motor 4 can be used to drive the rotation and tumbling heating.

[0034] The rotary drive motor 4 drives the drive wheel 41 to rotate, and the drive wheel 41 drives the calcining furnace body 1 to rotate via the transmission belt. During the rotation of the calcining furnace body 1, the transmission gear ring 14 inside it rotates. During the rotation of the transmission gear ring 14, the transmission gear ring 14 drives the rotating gear ring 131 and the heating inner cylinder 13 connected to it to rotate via two sets of transmission gears 15. This achieves synchronous rotation of the heating inner cylinder 13 and the calcining furnace body 1. When the calcining material comes into contact with the inner wall of the calcining furnace body 1, it undergoes a tumbling action. When the calcined material is lifted and comes into contact with the outer wall of the heating inner cylinder 13, it undergoes another tumbling action. This two tumbling actions achieve more uniform heating. Furthermore, the material can be quickly tilted during feeding by adjusting the tilt. The above is the working principle of this calcining device.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
