Description
A horizontal production and processing equipment integrating drying and calcination Technical Field
[0001] This utility model relates to the field of mica processing technology, and in particular to a horizontal production and processing equipment that integrates drying and calcination. Background Technology
[0002] The processing of mica generally includes: manually or mechanically screening natural mica fragments to remove impurities such as mud, sand, and iron filings; rinsing the mica fragments with deionized water; removing surface moisture through a drum dryer or airflow dryer; and then calcining to dehydrate the mica, causing it to expand vertically along the cleavage plane at high temperatures, forming a loose and porous structure that facilitates subsequent grinding to obtain mica powder.
[0003] In existing technologies, the drying and calcination of mica are usually completed using different equipment. However, transferring mica between different equipment is not only time-consuming, but also easily subject to external environmental pollution during the transfer process, affecting the quality of the finished product. In order to eliminate this impact, some advanced manufacturers have adopted integrated processing equipment, such as rotary kilns and continuous drying and calcination integrated equipment.
[0004] However, in rotary kilns and continuous drying and calcining equipment, there is a large temperature difference between the temperature required for drying (usually around 120℃) and the temperature required for calcination (usually >600℃). Therefore, a long transition zone is set between the drying zone and the calcination zone to avoid the temperature of the calcination zone and the drying zone from affecting each other and causing the drying and calcination to fail to achieve the expected results. However, the long transition zone results in a large area occupied by the equipment, which is not conducive to installation and use in small spaces. Therefore, a horizontal production and processing equipment that integrates drying and calcination is needed. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to provide a horizontal production and processing equipment that integrates drying and calcination, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A horizontal production and processing equipment integrating drying and calcination includes a fixed furnace body and a rotating furnace body that is rotatably connected to the lower end of the fixed furnace body. The upper part of the rotating furnace body extends into the fixed furnace body and is used for conveying materials. The fixed furnace body is provided with a feeding mechanism and a discharging mechanism, which are arranged adjacent to each other. In the annular area between the feeding mechanism and the discharging mechanism of the fixed furnace body, a drying zone, an isolation zone, a calcination zone and a cooling zone are sequentially distributed along the rotation direction of the rotating furnace body.
[0008] The isolation zone of the fixed furnace body is designed with partitions, and both ends of the isolation zone are fixedly connected to and communicate with the fixed furnace body through heat-insulated connecting frames.
[0009] The isolation zone is equipped with a closed isolation mechanism that divides the isolation zone into multiple insulated chambers. The closed isolation mechanism opens intermittently as the rotating furnace body rotates to allow materials to pass through.
[0010] Preferably, the closed isolation mechanism includes a heat insulation plate, which is fixed to the inner wall of the isolation area. Multiple heat insulation plates are provided and evenly distributed at equal intervals along the isolation area, and the multiple heat insulation plates divide the isolation area into multiple heat insulation chambers.
[0011] Preferably, the closed isolation mechanism further includes a matching isolation block, which is fixed in the groove of the rotating furnace body that carries the material;
[0012] Multiple isolation blocks are also provided and evenly distributed along the grooves of the rotating furnace body;
[0013] When the upper end of the isolation block comes into contact with the lower end of the insulation plate during rotation, the insulation plate and the isolation block form a closed isolation unit between the rotating furnace body and the isolation zone.
[0014] Preferably, the heat insulation board is a board made of heat insulation material, and the heat insulation board is densely covered with honeycomb-shaped cavities.
[0015] As another improvement to the technical solution of this application, the closed isolation mechanism includes a bendable insulation door, and the vertical cross-section of the bendable insulation door is the same size as the cross-sectional structure of the channel formed between the isolation area and the groove of the rotating furnace body.
[0016] The upper part of the bendable insulated door is fixed to the inner wall of the isolation zone, and the lower part of the bendable insulated door can be rotated and opened in the direction of rotation of the rotating furnace body. The sealing isolation mechanism also includes a trigger for opening the lower part of the bendable insulated door, and the trigger is fixed to the rotating furnace body.
[0017] Preferably, the bendable insulation door includes a fixed plate, a movable plate, and a torque rotation mechanism. The fixed plate is fixed to the inner wall of the isolation area. The upper end of the movable plate is rotatably connected to the lower end of the fixed plate through the torque rotation mechanism. An extension plate extending into the groove of the rotating furnace body is formed at the lower end of the movable plate. A notch abutting against the upper end of the rotating furnace body is formed at the upper end of the extension plate of the movable plate.
[0018] When the trigger rotates with the rotating furnace body, it abuts against the notch and pushes the movable plate open. The torque rotation mechanism can also drive the movable plate to reset after it is separated from the trigger.
[0019] Preferably, the triggering element includes an abutment block, which is fixed to the upper end of the rotating furnace body. A first guide wall is formed on the side of the abutment block facing the rotation direction of the rotating furnace body. The first guide wall is a concave arc-shaped wall.
[0020] A second guide wall is formed on the side of the abutment block that is opposite to the direction of rotation of the rotating furnace body. The second guide wall is an outwardly convex arc-shaped wall.
[0021] Preferably, there are several bendable heat shields evenly distributed in the isolation area, and several abutment blocks are arranged in a ring on the upper end of the rotating furnace body. The spacing between the multiple abutment blocks is different, and the spacing between the multiple abutment blocks that are the same number as the number of bendable heat shields is different from the spacing between two adjacent bendable heat shields.
[0022] In summary, the technical effects and advantages of this utility model are as follows:
[0023] This utility model designs the isolation zone as a separate unit and separates and connects the isolation zone with the fixed furnace body through a heat-insulating connecting frame, thereby cutting off the heat transfer path between the calcination zone and the drying zone on the fixed furnace body and achieving the effect of preventing heat from affecting each other.
[0024] Meanwhile, by using a closed isolation mechanism to divide the isolation area into multiple insulated chambers, the heat insulation effect of the isolation area is improved. Multiple insulated chambers can greatly reduce the heat conduction efficiency, thereby reducing the length of the isolation area. This reduces the overall size of the horizontal production and processing equipment that integrates drying and calcination, allowing the equipment to be installed and used in a small space, increasing the installation space range, and facilitating the promotion and use of the equipment. At the same time, reducing the length of the isolation area can also reduce the cost of the equipment, making it more conducive to its widespread use.
[0025] This invention designs multiple abutment blocks in a variable-distance distribution, which allows adjacent bendable heat insulation doors to contact adjacent abutment blocks at different times. This results in adjacent bendable heat insulation doors opening at different times, forming a staggered opening and closing state. This avoids direct connection between the drying zone and the calcination zone when the entire isolation zone is opened, ensuring that the isolation zone always plays its role in isolation and further improving the barrier effect of the isolation zone.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0034] Example 1
[0035] Referring to Figures 1-3, a horizontal production and processing equipment integrating drying and calcination is shown, including a fixed furnace body 1 and a rotating furnace body 2 that is rotatably connected to the lower end of the fixed furnace body 1. The upper part of the rotating furnace body 2 extends into the fixed furnace body 1 and is used to convey materials (referring to mica, the same below). The fixed furnace body 1 is provided with a feeding mechanism 11 and a discharging mechanism 12, which are arranged adjacent to each other. In the annular area between the feeding mechanism 11 and the discharging mechanism 12 of the fixed furnace body 1, a drying zone 13, an isolation zone 14, a calcination zone 15 and a cooling zone 16 are distributed sequentially along the rotation direction of the rotating furnace body 2.
[0036] It should be noted that the horizontal production and processing equipment integrating drying and calcination should also have other structures commonly used in the prior art to realize the overall drying and calcination functions of the equipment, such as a drive mechanism to drive the rotating furnace body 2 to rotate, a conveying pipeline to input natural gas into the calcination zone 15 for combustion to calcine the material, and an air supply mechanism to input hot air into the drying zone 13 for drying. The above structures are all in the prior art, so they will not be listed one by one here, and their specific structures and working principles will not be elaborated here either.
[0037] The isolation zone 14 of the fixed furnace body 1 is a partition design, and both ends of the isolation zone 14 are fixedly connected to and communicate with the fixed furnace body 1 through the heat insulation connection frame 3;
[0038] The isolation zone 14 is equipped with a closed isolation mechanism, which divides the isolation zone 14 into multiple heat-insulated chambers. The closed isolation mechanism opens intermittently as the rotating furnace body 2 rotates to allow materials to pass through.
[0039] Based on the above structure, by designing the isolation zone 14 as a separate unit and separating and connecting the isolation zone 14 with the fixed furnace body 1 through the heat insulation connection frame 3, the heat transfer path between the calcination zone 15 and the drying zone 13 on the fixed furnace body 1 is cut off, thereby achieving the effect of preventing heat from affecting each other.
[0040] Meanwhile, by using a closed isolation mechanism to divide the isolation zone 14 into multiple heat-insulating chambers, the heat insulation effect of the isolation zone 14 is improved. Multiple heat-insulating chambers can greatly reduce the heat conduction efficiency, thereby reducing the length of the isolation zone 14. This reduces the overall size of the horizontal production and processing equipment that integrates drying and calcination, allowing the equipment to be installed and used in a small space, increasing the installation space range of the equipment, and facilitating its widespread use. At the same time, reducing the length of the isolation zone 14 can also reduce equipment costs to a certain extent, making it more conducive to widespread use.
[0041] Furthermore, the closed isolation mechanism includes a heat insulation plate 4, which is fixed to the inner wall of the isolation area 14. Multiple heat insulation plates 4 are provided and are evenly distributed at equal intervals along the isolation area 14. The multiple heat insulation plates 4 divide the isolation area 14 into multiple heat insulation chambers.
[0042] The closed isolation mechanism also includes a matching isolation block 5, which is fixed in the groove of the rotating furnace body 2 that carries the material;
[0043] Multiple isolation blocks 5 are also provided and evenly distributed along the groove of the rotating furnace body 2;
[0044] By using the heat insulation plate 4 and the matching isolation block 5, the isolation zone 14 is divided into multiple heat insulation chambers. In addition, during the material conveying process of the rotating furnace body 2, when the upper end of the matching isolation block 5 moves and abuts against the lower end of the heat insulation plate 4 during the rotation, the heat insulation plate 4 and the matching isolation block 5 form a closed isolation whole between the rotating furnace body 2 and the isolation zone 14, thereby achieving a good sealing and blocking effect, reducing the heat conduction efficiency, and at the same time not affecting the material conveying, ensuring the normal operation of the equipment.
[0045] It should be noted that when the heat insulation plate 4 is separated from the matching isolation block 5, the heat conduction cross section between the drying zone 13 and the calcination zone 15 is also restricted and reduced by the heat insulation plate 4, thus also having the effect of reducing heat conduction efficiency.
[0046] Furthermore, the heat insulation board 4 is a board made of heat insulation material (such as aerogel), and the heat insulation board 4 is densely covered with honeycomb cavities, which can maximize the heat insulation effect and further enhance the heat transfer barrier function of the isolation zone 14. It can achieve the expected heat insulation effect while further reducing the length of the isolation zone 14.
[0047] Example 2
[0048] Referring to Figures 4-5, a horizontal production and processing equipment integrating drying and calcination is shown. The difference between this equipment and Example 1 is that the closed isolation mechanism includes a bendable door 6. The vertical cross-section of the bendable door 6 and the cross-sectional structure of the channel formed between the isolation zone 14 and the groove of the rotating furnace body 2 are the same size.
[0049] The upper part of the bendable door 6 is fixed to the inner wall of the isolation zone 14, and the lower part of the bendable door 6 can be rotated and opened in the direction of rotation of the rotating furnace body 2. Specifically, the bendable door 6 includes a fixed plate 61, a movable plate 62 and a torque rotation mechanism 63. The fixed plate 61 is fixed to the inner wall of the isolation zone 14. The upper end of the movable plate 62 is rotatably connected to the lower end of the fixed plate 61 through the torque rotation mechanism 63. An extension plate 621 extending into the groove of the rotating furnace body 2 is formed at the lower end of the movable plate 62. A notch 622 abutting against the upper end of the rotating furnace body 2 is formed at the upper end of the extension plate 621 of the movable plate 62.
[0050] The closed isolation mechanism also includes a trigger for opening the lower part of the bendable insulation door 6. The trigger is fixed on the rotating furnace body 2. When the trigger rotates with the rotating furnace body 2, it abuts against the notch 622 and opens the movable plate 62. The torque rotation mechanism 63 can also drive the movable plate 62 to reset after it is separated from the trigger.
[0051] Specifically, the triggering element includes an abutment block 7, which is fixed to the upper end of the rotating furnace body 2. A first guide wall 71 is formed on the side of the abutment block 7 facing the rotation direction of the rotating furnace body 2. The first guide wall 71 is a concave arc-shaped wall.
[0052] A second guide wall 72 is formed on the side of the abutment block 7 opposite to the rotation direction of the rotating furnace body 2. The second guide wall 72 is an outwardly convex arc-shaped wall.
[0053] As the abutting block 7 rotates with the rotating furnace body 2, the first guide wall 71 first abuts against the lower end of the notch 622 and applies a pushing force to the movable plate 62 during its forward movement. This causes the movable plate 62 to overcome the torque of the torque rotation mechanism 63 and rotate open in the direction of rotation of the rotating furnace body 2, thus facilitating the passage of materials in the groove of the rotating furnace body 2. Afterward, the movable plate 62 slides along the second guide wall 72 and gradually closes, thereby achieving the effect of both closing the isolation zone 14 to form multiple isolation cavities to block heat transfer and intermittently opening to allow materials to pass through.
[0054] In addition, the first guide wall 71 and the second guide wall 72 can guide the movable plate 62 so that it moves slowly when opening and closing, thus preventing the material in the groove of the rotating furnace body 2 from being thrown out.
[0055] Furthermore, several bendable heat shield doors 6 are evenly distributed within the isolation zone 14, and multiple abutment blocks 7 are arranged in a ring on the upper end of the rotating furnace body 2. The spacing between the multiple abutment blocks 7 is different, and the spacing between several abutment blocks 7, which are the same number as the bendable heat shield doors 6, is different from the spacing between two adjacent bendable heat shield doors 6. Through the above arrangement, the contact time between adjacent bendable heat shield doors 6 and adjacent abutment blocks 7 is different, thereby making the opening time of two adjacent bendable heat shield doors 6 different, forming a staggered opening and closing state. This avoids the drying zone 13 and the calcining zone 15 from being directly connected after the isolation zone 14 is fully opened, so that the isolation zone 14 can always play an isolation role, further improving the barrier effect of the isolation zone 14.
[0056] It should be further explained that, in other embodiments, the plurality of cooperating isolation blocks 5 in embodiment 1 can be configured in the same distribution manner as the plurality of abutting blocks 7, so that the isolation area 14 in embodiment 1 can also achieve the purpose of always playing an isolation role.
[0057] The working principle of this utility model is as follows: In daily use, by designing the isolation zone 14 as a separate unit and separating and connecting the isolation zone 14 with the fixed furnace body 1 through the heat insulation connection frame 3, the heat transfer path between the calcination zone 15 and the drying zone 13 on the fixed furnace body 1 is cut off, thereby achieving the effect of preventing heat from affecting each other.
[0058] Meanwhile, by using a closed isolation mechanism to divide the isolation zone 14 into multiple heat-insulating chambers, the heat insulation effect of the isolation zone 14 is improved. Multiple heat-insulating chambers can greatly reduce the heat conduction efficiency, thereby reducing the length of the isolation zone 14. This reduces the overall size of the horizontal production and processing equipment that integrates drying and calcination, allowing the equipment to be installed and used in a small space, increasing the installation space range of the equipment, and facilitating its widespread use. At the same time, reducing the length of the isolation zone 14 can also reduce equipment costs to a certain extent, making it more conducive to widespread use.
[0059] This utility model has been described with reference to the above-described embodiments and accompanying drawings. However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. On the contrary, modifications and equivalent provisions included in the spirit and scope of the claims are all included within the scope of this utility model.
