Description

Technical Field

[0001] This utility model belongs to the technical field of calcination equipment, specifically relating to a calcination equipment for processing autumn ice salt. Background Technology

[0002] Autumn ice salt is a natural salt resource containing a variety of mineral components. Calcination is a key process in its processing, aimed at removing water of crystallization and volatile matter, thereby altering the physicochemical properties of the material to improve its purity and application value.

[0003] Currently, the traditional calcination equipment commonly used in autumn ice salt processing mainly includes coal-fired rotary kilns and electromagnetic coil rotary kilns. The heat transfer process in traditional coal-fired rotary kilns is extremely complex. The heat generated by coal combustion must be transferred to the autumn ice salt through a series of media, resulting in significant heat loss. On the one hand, some heat is discharged as waste gas during combustion, not fully utilized for heating the material; on the other hand, heat dissipation from the kiln body also leads to a large waste of thermal energy. This high-energy-consumption and low-efficiency heating method makes the heating rate of autumn ice salt extremely slow, hindering the improvement of production efficiency.

[0004] While rotary kilns using electromagnetic coils employ the principle of electromagnetic induction heating and seem to possess the potential for high-efficiency heating, their actual performance falls short of expectations. The electromagnetic coils are wound on the outside of the kiln body, and the alternating magnetic field must penetrate multiple layers of the kiln structure, such as refractory and insulation layers, to act on the internal materials. This not only weakens the effective magnetic field strength, slowing down the heating rate, but also leads to significant heat loss. On one hand, heat radiates directly into the surrounding environment; on the other hand, the air gap between the kiln body and the coil creates an inefficient heat transfer zone, further exacerbating heat loss. Furthermore, as the rotary kiln rotates, the relative positions of the kiln body and the coil constantly change, resulting in unstable coupling between the magnetic field and the heated object, affecting heating uniformity and efficiency. To ensure heating effectiveness, the heating time must be extended, further reducing production efficiency.

[0005] Therefore, in order to solve the above problems, it is necessary to design a calcination device for processing autumn ice salt. Utility Model Content

[0006] The purpose of this invention is to provide a calcination device for processing autumn ice salt, so as to solve the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a calcination device for processing autumn ice salt, comprising: The rotary kiln body has several circular arrays of lifting plates on its inner wall; The heating assembly includes: a heat-conducting sleeve disposed inside the rotary kiln body and a heating tube spirally disposed inside the heat-conducting sleeve; The rotating assembly includes: a gear ring fitted in the middle of the rotary kiln body, a geared motor disposed on one side of the rotary kiln body, and a gear fitted at the output end of the geared motor; wherein... The gear meshes with the gear ring; Two auxiliary rotating components are used to support and assist the rotation of the rotary kiln body; The geared motor is adapted to start when the heating tube is turned on, so as to drive the rotary kiln body to rotate on the two auxiliary rotating components through gears and gear rings. The rotary kiln body drives the lifting plate to move, so that the autumn ice salt tumbles in the rotary kiln body.

[0008] Furthermore, the heating assembly also includes: support seats disposed on both sides of the rotary kiln body; wherein Both of the aforementioned support bases are connected to the heat-conducting sleeve.

[0009] Furthermore, the outer side of the rotary kiln body is provided with two insulation layers; wherein The two insulation layers are located on both sides of the gear ring.

[0010] Furthermore, the rotary kiln body is inclinedly mounted on two auxiliary rotating components; wherein The high end of the rotary kiln body is the feed inlet; The lower end of the rotary kiln body is the discharge port; and The heat-conducting sleeve is concentrically arranged with the rotary kiln body.

[0011] Furthermore, the auxiliary rotation assembly includes: a base, an arc-shaped frame connected to the base bearing, and a plurality of pairs of rollers disposed within the arc-shaped frame; wherein Each of the rollers is adapted to roll within the arcuate frame; and Each of the rollers is adapted to contact the rotary kiln body.

[0012] The beneficial effects of this utility model are: (I) When the heating tube is turned on, this utility model generates heat and transfers it to the autumn ice salt inside the rotary kiln through the heat-conducting sleeve. Simultaneously, the geared motor starts, and the gear at its output end rotates. Since the gear meshes with the gear ring sleeved in the middle of the rotary kiln, it drives the rotary kiln to rotate on two auxiliary rotating components. As the rotary kiln rotates, the lifting plates on its inner wall move accordingly, causing the autumn ice salt to continuously tumble within the kiln, ensuring that the autumn ice salt can fully absorb heat in a uniform thermal environment and tumbling motion, thus completing the calcination. The spiral arrangement of the heating tube inside the heat-conducting sleeve allows for more even heat transfer to the material, reducing heat loss. At the same time, the rotation of the rotary kiln causes the lifting plates to move, continuously tumbling the autumn ice salt, ensuring full contact between the material and heat, improving heat utilization efficiency while guaranteeing calcination quality.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0019] like Figures 1 to 4 As shown, this embodiment provides a calcination device for processing autumn ice salt, including: A rotary kiln body 1 has several circularly arranged lifting plates 101 on its inner wall; a heating assembly 2 includes a heat-conducting sleeve 201 disposed inside the rotary kiln body 1 and a heating tube 202 spirally disposed inside the heat-conducting sleeve 201; a rotating assembly 3 includes a gear ring 301 sleeved in the middle of the rotary kiln body 1, a reduction motor 302 disposed on one side of the rotary kiln body 1, and a gear 303 sleeved at the output end of the reduction motor 302; wherein the gear 303 meshes with the gear ring 301; two auxiliary rotating assemblies 4 are used to support and assist the rotation of the rotary kiln body 1; the reduction motor 302 is adapted to start when the heating tube 202 is turned on, so as to drive the rotary kiln body 1 to rotate on the two auxiliary rotating assemblies 4 through the gear 303 and the gear ring 301. The body 1 drives the lifting plate 101 to move, causing the autumn ice salt to tumble inside the rotary kiln body 1. The lifting plate 101 rotates with the rotary kiln body 1, causing the autumn ice salt to tumble within the kiln body 1, thus achieving more uniform heating of the material, avoiding localized overheating or under-firing, and ensuring calcination quality. The heat-conducting sleeve 201 protects the heating tube 202 while conducting heat, evenly transferring the heat generated by the heating tube 202 to the autumn ice salt inside the rotary kiln body 1, improving heat utilization and allowing the material to fully absorb heat for calcination. The heating tube 202 is spirally positioned inside the heat-conducting sleeve 201, providing all-around heating of the sleeve and thus providing stable and sufficient heat energy for the calcination of the autumn ice salt.

[0020] In this embodiment, when the heating tube 202 is turned on, heat is generated and transferred to the autumn ice salt inside the rotary kiln body 1 through the heat-conducting sleeve 201. Simultaneously, the reduction motor 302 starts, and its output gear 303 rotates accordingly. Since the gear 303 meshes with the gear ring 301 fitted in the middle of the rotary kiln body 1, it drives the rotary kiln body 1 to rotate on the two auxiliary rotating components 4. As the rotary kiln body 1 rotates, the lifting plates 101 on its inner wall move accordingly, causing the autumn ice salt to continuously tumble inside the rotary kiln body 1. This ensures that the autumn ice salt can fully absorb heat in a uniform thermal environment and tumbling motion, completing the calcination. The spiral arrangement of the heating tube 202 inside the heat-conducting sleeve 201 allows for more even heat transfer to the material, reducing heat loss. At the same time, the rotation of the rotary kiln body 1 drives the lifting plates 101 to move, causing the autumn ice salt to continuously tumble, ensuring full contact between the material and heat, improving heat utilization efficiency while guaranteeing calcination quality.

[0021] The heating assembly 2 further includes: support seats 203 disposed on both sides of the rotary kiln body 1; wherein the two support seats 203 are connected to the heat-conducting sleeve 201; wherein by setting the support seats 203, the heat-conducting sleeve 201 is fixed and supported, so that the heat-conducting sleeve 201 can be stably placed inside the rotary kiln body 1, avoiding shaking or displacement during the rotation of the rotary kiln body 1, thereby ensuring the stability and reliability of the heating assembly 2.

[0022] The rotary kiln body 1 is provided with two insulation layers 102 on the outside; the two insulation layers 102 are located on both sides of the toothed ring 301; by setting the insulation layers 102, the heat loss from the inside of the rotary kiln body 1 to the outside can be effectively reduced, the stable ambient temperature inside the rotary kiln body 1 can be maintained, and energy consumption can be reduced.

[0023] The rotary kiln body 1 is inclinedly mounted on two auxiliary rotating components 4; the high end of the rotary kiln body 1 is the feed inlet 103; the low end of the rotary kiln body 1 is the discharge outlet 104; and the heat-conducting sleeve 201 is concentrically mounted with the rotary kiln body 1. By inclinedly mounting the rotary kiln body 1 on the two auxiliary rotating components 4, with the high end being the feed inlet 103 and the low end being the discharge outlet 104, the autumn ice salt added to the feed inlet 103 slowly moves towards the discharge outlet 104 along the inclined direction during the rotation of the rotary kiln body 1, achieving continuous material conveying. The concentric mounting of the heat-conducting sleeve 201 with the rotary kiln body 1 ensures uniform heat transfer.

[0024] The auxiliary rotation assembly 4 includes: a base 401, an arc-shaped frame 402 connected to the base 401 by a bearing, and a plurality of pairs of rollers 403 disposed within the arc-shaped frame 402; wherein each roller 403 is adapted to roll within the arc-shaped frame 402; and each roller 403 is adapted to contact the rotary kiln body 1; wherein by setting the arc-shaped frame 402 to be connected to the base 401 by a bearing, the arc-shaped frame 402 can rotate flexibly relative to the base 401, so as to better fit the tilt angle of the rotary kiln body 1 when it is tilted; by setting each roller 403, the friction force during the rotation of the rotary kiln body 1 is reduced, making the rotation of the kiln body smoother.
