Description

Technical Field

[0001] This utility model relates to the field of ceramic firing equipment technology, specifically a multi-layer adjustable electric ceramic kiln. Background Technology

[0002] With the increasing demand for ceramic products, the firing process of ceramic blanks is receiving more and more attention. As one of the key processes, ceramic firing places higher demands on the precision of temperature control, the uniformity of heating, and production efficiency. Currently, most widely used electric kilns adopt single-layer or fixed multi-layer structures, and the positions of the layers are not adjustable. The heating position of the ceramic blanks is fixed, which easily leads to uneven firing. Especially when multiple layers are densely arranged, the problem of uneven heat distribution is particularly prominent, directly affecting the quality of the finished product.

[0003] To alleviate the above problems, some existing technologies have introduced simple shelf lifting devices, but they generally have the following drawbacks:

[0004] Simple structure and lack of flexibility: Most electric furnace racks are fixed or can only be adjusted manually, and do not have dynamic adjustment capabilities.

[0005] Inaccurate temperature control: The heating position of the ceramic body during the firing process cannot be adjusted according to the temperature zone, resulting in low temperature control accuracy and unstable yield.

[0006] Uneven heating: The upper and lower ceramic blanks are kept at a fixed distance from the heat source for a long time, resulting in uneven heat distribution and large differences in firing results;

[0007] Low level of automation: Most traditional kilns do not have a circulating operation function, which makes it impossible to realize the automatic circulating firing of batches of blanks, thus affecting production efficiency.

[0008] In summary, existing electric ceramic kilns still have significant limitations in terms of structural design and intelligence. There is an urgent need for a multi-layer electric ceramic kiln system with a reasonable structure, adjustable height, stable operation, and high temperature control accuracy to improve firing consistency and efficiency and meet the needs of modern ceramic production. Summary of the Invention

[0009] The purpose of this invention is to overcome the technical problems of uneven heating of ceramic blanks, low temperature control accuracy, and inconvenient lifting and adjustment in existing ceramic electric kilns, and to provide a multi-layer adjustable ceramic electric kiln with simple structure, stable operation, and the ability to realize the cyclic lifting and lowering of multiple layers of ceramic blanks, so as to improve the consistency and efficiency of ceramic firing.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A multi-layer adjustable electric ceramic kiln includes: an electric kiln, a drive assembly, and a shelf basket assembly. The electric kiln has an internal support frame for supporting the drive mechanism and the shelf system. The drive assembly and the shelf basket assembly are mounted on the support frame. The drive assembly drives multiple shelf basket assemblies to rotate cyclically in the vertical direction to realize the lifting and lowering movement and position adjustment of the ceramic blank.

[0012] The drive assembly includes: upper and lower transmission gears mounted on the upright; a chain belt sleeved between the two transmission gears; multiple moving ears evenly mounted on the chain belt; a drive motor mounted outside the electric furnace, the output end of which is connected to one of the transmission gears; and several transmission pins on the chain belt that mesh with the transmission gears to achieve synchronous transmission.

[0013] The shelf basket assembly includes: a lifting shaft and shelves rotatably connected at both ends by lifting lugs; the two ends of the lifting shaft are rotatably connected to the moving lugs on the drive assembly to achieve synchronous lifting and lowering of the whole assembly; the drive assembly is set into two sets, respectively installed on the left and right sides of the upright frame and arranged symmetrically; the shelves and lifting lugs are detachably connected for easy maintenance and replacement; the drive motor adopts a variable frequency speed control device, which can achieve precise height adjustment of the shelf basket assembly; the surface of the upright frame is equipped with guide rails to guide the lifting shaft during the lifting process and prevent structural swaying and displacement.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the meshing of the chain belt and the transmission gear plate, combined with the moving ear and lifting shaft structure, the cyclic lifting of multiple layer basket groups can be realized, effectively solving the problem of uneven temperature control during the firing process of ceramic blanks;

[0016] The drive motor adopts frequency conversion control to achieve precise adjustment of the shelf height, allowing the ceramic blank to be moved away from or closer to the heating source according to process requirements, thus improving the flexibility and accuracy of temperature control.

[0017] With its simple overall structure and reliable operation, it is suitable for mass production of ceramic blanks and has good application value. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] like Figures 1 to 4 As shown, a multi-layer adjustable electric ceramic kiln includes an electric kiln 100, a drive assembly 200, and a shelf basket assembly 300. The electric kiln 100 is equipped with a support frame 110 to support the entire lifting and circulation system.

[0029] The drive assembly 200 and the shelf basket assembly 300 are respectively fixed or installed on the upright frame 110. The function of the drive assembly 200 is to drive the multiple shelf basket assemblies 300 to perform synchronous lifting and cyclic movement in the vertical direction, thereby achieving precise temperature control and uniform heating of the ceramic blank during the firing process.

[0030] Specifically, the drive assembly 200 includes a transmission gear 210, a chain 220, several moving lugs 230, and a drive motor 240. The two transmission gears 210 are rotatably mounted at the upper and lower ends of the frame 110, respectively, and the chain 220 is sleeved between the two transmission gears to form a cyclic rotation structure.

[0031] A plurality of moving lugs 230 are evenly arranged on the chain belt 220 for connection with the shelf basket assembly 300, thereby achieving synchronous lifting and lowering. A plurality of transmission pins 221 are also provided on the chain belt for meshing with the transmission gear disc 210 to achieve reliable transmission function. The drive motor 240 is located outside the electric furnace 100, and its output end is directly connected to a transmission gear disc 210 at the bottom, driving the entire chain belt mechanism to rotate.

[0032] The shelf basket assembly 300 includes a lifting shaft 310, shelves 320, and lifting lugs 321. Both ends of the shelves 320 are rotatably connected to the lifting shaft 310 via the lifting lugs 321, forming a rotatable load-bearing structure. The upper and lower ends of the lifting shaft 310 are respectively connected to multiple moving ears 230 on two drive assemblies 200 via pin structures, forming a stable lifting system.

[0033] To ensure structural stability, the lifting shaft 310 and the moving ear 230 are connected by a pin with a limit switch to prevent axial sliding during operation. To further improve operational stability, the surface of the upright frame 110 is also provided with a guide rail to guide the running trajectory of the lifting shaft 310 during the lifting process, preventing the shelf basket assembly 300 from shifting or shaking.

[0034] Preferably, the drive assembly 200 is configured as two sets, respectively installed on the left and right sides of the support frame 110 in a symmetrical arrangement to ensure the balance and synchronization of the shelf basket assembly 300 during operation. The drive motor 240 adopts a variable frequency speed control device, which can adjust the running speed and height of the shelf basket assembly according to the temperature control requirements, so that the ceramic blank can accurately approach or move away from the heating source, thereby improving the temperature control accuracy.

[0035] In addition, for ease of daily maintenance and operation, the connection point between the shelf 320 and the lifting lug 321 is a detachable structure, which facilitates the replacement of damaged parts or cleaning operations, thereby improving the maintainability and service life of the equipment.

[0036] The structure described in this utility model achieves synchronous lifting and cyclic operation of multiple layer baskets in the vertical direction through chain circulation and symmetrical drive, thereby realizing multi-layer staggered temperature control and uniform heating of the ceramic blank. It is suitable for batch ceramic firing scenarios and has significant advantages in terms of efficiency and temperature control accuracy.
