Description

Technical Field

[0001] This utility model relates to the field of purple pottery processing, and in particular to a purple pottery firing furnace with uniform heating. Background Technology

[0002] Ceramics is a general term for pottery and porcelain. Most ceramic materials are oxides, nitrides, borides and carbides. Common ceramic materials include clay, alumina and kaolin. Purple pottery is a type of ceramic product. In the production process of purple pottery, firing is one of the key steps, and its firing effect directly affects the quality and appearance of purple pottery.

[0003] When firing purple pottery, a firing kiln is required. However, traditional firing kilns usually use a single heating method, such as setting heating elements at the bottom or side of the kiln body. This can easily lead to uneven heating of different parts of the product, resulting in different firing effects between the upper and lower parts and reducing the firing effect of the kiln on purple pottery. To address this issue, we propose a purple pottery firing kiln with uniform heating. Utility Model Content

[0004] The purpose of this invention is to provide a uniformly heated purple pottery firing furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A uniformly heated purple pottery firing furnace includes a support plate, a firing furnace body fixedly mounted on the upper surface of the support plate, a lifting cover slidably connected to the outer surface of the firing furnace body, a top heating element above the lifting cover, two driving elements below the support plate, a geared motor fixedly mounted on the bottom surface of the support plate, a rotating shaft fixedly mounted on the output end of the geared motor, a rotating disk fixedly mounted on the top end of the rotating shaft, and an arc-shaped electric heating wire fixedly embedded inside the firing furnace body.

[0007] Preferably, the top heating element includes an annular cover fixedly embedded in the upper surface of the lifting cover, an annular electric heating wire fixedly installed on the inner top wall of the top heating element, and an annular heating plate fixedly installed on the bottom surface of the annular electric heating wire.

[0008] Preferably, a support slide is fixedly installed on the back of the support plate, a support plate is slidably connected to the inner wall of the support slide, one side of the support plate is fixedly installed to the outer surface of the lifting cover, and a controller is fixedly installed on the outer surface of the support slide.

[0009] Preferably, both driving components include a support base fixedly installed on the bottom surface of the support plate, a support plate fixedly installed on the side of the two support bases that are far apart from each other, an electric cylinder fixedly installed on the telescopic end of the two support plates, a connecting plate fixedly installed on the telescopic end of the two electric cylinders, and a fixed connection to the outer surface of the lifting cover on the side of the two connecting plates that are close to each other.

[0010] Preferably, a sensing cover is fixedly embedded on the upper surface of the lifting cover, and a temperature sensor is fixedly installed on the inner top wall of the sensing cover.

[0011] Preferably, the outer surface of the firing furnace body has two protective doors hinged by pins, and the upper surface of the support plate is fixedly inlaid with a bearing, the inner ring of the bearing being fixedly connected to the outer surface of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an arc-shaped electric heating wire installed in the firing furnace body to heat the purple ceramic piece from the side above the rotating disk. In addition, the annular electric heating wire, together with the annular heating plate, can heat the top of the purple ceramic piece above the rotating disk, forming a multi-directional heat transfer. This avoids the problem of local over-firing or under-firing caused by traditional single heating. Furthermore, the use of a geared motor to drive the rotation of the rotating shaft and the rotating disk allows the purple ceramic piece to rotate in all directions, ensuring uniform heating of all parts of the purple ceramic piece. This solves the problem of limited heating caused by fixed position in traditional firing and ensures the uniformity of the firing effect. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4In this utility model, a uniformly heated purple pottery firing furnace includes a support plate 1. A firing furnace body 2 is fixedly installed on the upper surface of the support plate 1. A lifting cover 3 is slidably connected to the outer surface of the firing furnace body 2. A top heating element 4 is provided above the lifting cover 3. Two driving elements 6 are provided below the support plate 1. A reduction motor 7 is fixedly installed on the bottom surface of the support plate 1. A rotating shaft 8 is fixedly installed at the output end of the reduction motor 7. A rotating disk 12 is fixedly installed at the top of the rotating shaft 8. An arc-shaped electric heating wire 10 is fixedly embedded inside the firing furnace body 2. The arc-shaped electric heating wire 10 embedded inside the firing furnace body 2 can provide side heat. At the same time, the reduction motor 7 drives the rotation of the rotating shaft 8 and the rotating disk 12. The purple pottery can be heated evenly from all directions above the rotating disk 12, solving the problem of uneven heating caused by traditional single heating. In addition, the larger firing furnace body 2 requires more heat to evenly heat the internal space. Therefore, it may be necessary to use electric heating wires with higher power. The actual power model needs to be determined according to the specific design parameters of the firing furnace and the firing process requirements of the purple pottery.

[0023] In a further embodiment, the top heating element 4 includes an annular cover 401 fixedly embedded on the upper surface of the lifting cover 3. An annular electric heating wire 402 is fixedly installed on the inner top wall of the top heating element 4, and an annular heating plate 403 is fixedly installed on the bottom surface of the annular electric heating wire 402. Heat is generated by the annular electric heating wire 402 inside the annular cover 401 and transferred downward through the annular heating plate 403 to achieve top heating. A support slide 13 is fixedly installed on the back of the support plate 1, and a support slide plate 14 is slidably connected to the inner wall of the support slide plate 13. One side of the support slide plate 14... The controller 15 is fixedly installed on the outer surface of the lifting cover 3 and the outer surface of the support slide 13. Two protective doors 16 are hinged to the outer surface of the firing furnace body 2 by a pin. The upper surface of the support plate 1 is fixedly inlaid with a bearing 9. The inner ring of the bearing 9 is fixedly connected to the outer surface of the rotating shaft 8. By setting the support slide 13 and the support slide plate 14, the lifting cover 3 can be more stable when it moves up and down, and avoid shaking. By opening the protective door 16, it is convenient to pick up and put down materials. By setting the bearing 9, the rotation of the rotating shaft 8 can be more stable.

[0024] In a further embodiment, both driving components 6 include a support base 601 fixedly mounted on the bottom surface of the support plate 1. Support plates 602 are fixedly mounted on the sides of the two support bases 601 that are far apart from each other. Electric cylinders 603 are fixedly mounted on the telescopic ends of the two support plates 602. Connecting plates 604 are fixedly mounted on the telescopic ends of the two electric cylinders 603. The sides of the two connecting plates 604 that are close to each other are fixedly connected to the outer surface of the lifting cover 3. A sensing cover 5 is fixedly embedded in the upper surface of the lifting cover 3, and a temperature sensor is fixedly mounted on the inner top wall of the sensing cover 5. The temperature sensor 11, through the support base 601 and the support plate 602, allows the electric cylinder 603 to be installed. The electric cylinder 603 and the connecting plate 604 work together to facilitate the lifting cover 3 to rise, making it easier to operate during the internal maintenance of the firing furnace body 2. Through the setting of the sensing cover 5 and the temperature sensor 11, the furnace temperature is monitored in real time, and the data is fed back to the controller 15. Once the temperature is abnormal, the controller 15 automatically adjusts the power and working time of the arc-shaped electric heating wire 10 and the ring-shaped electric heating wire 402 to achieve precise temperature control.

[0025] The working principle of this utility model is as follows: First, open the protective door 16 and place the purple ceramic piece above the rotating disk 12. Then, the arc-shaped electric heating wire 10 provides heat from the side, while the annular electric heating wire 402 generates heat, which can be transferred downward through the annular heating plate 403 to achieve top heating. This allows the heat to be evenly transferred to the purple ceramic piece from different directions. Next, start the reduction motor 7 to drive the rotating shaft 8 to rotate, which will cause the rotating disk 12 at the top to rotate as well. The purple ceramic piece placed on it can be heated evenly from all directions, improving the firing effect. Furthermore, the temperature sensor 11 can monitor the furnace temperature in real time, and the data is fed back to the controller 15. Once the temperature does not meet the requirements, the controller 15 will automatically adjust the power and working time of the arc-shaped electric heating wire 10 and the annular electric heating wire 402 to facilitate temperature control during firing.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
