Description

Technical Field

[0001] The utility model relates to the technical field of ceramic firing equipment, in particular to a high-temperature shuttle kiln structure. Background Art

[0002] As a thermal equipment widely used in the ceramic industry, the shuttle kiln plays an important role in the firing process of ceramic products with its efficient and uniform heating characteristics. It usually adopts an intermittent operation mode, that is, after a batch of ceramic products are fired, the firing rack loaded with ceramics is pushed into or pulled out of the kiln as a whole to meet the needs of continuous production. This structural design not only improves production efficiency but also facilitates the control of temperature and atmosphere during the firing process, which has a significant effect on improving the quality of ceramic products.

[0003] An energy-efficient shuttle structure ceramic kiln disclosed in the patent with the publication number CN216925141U belongs to the technical field of ceramic processing, including a kiln chamber. A protective shell is arranged outside the kiln chamber. A chute is opened at the bottom of the kiln chamber. A kiln bottom plate is slidably arranged inside the chute. An installation plate is slidably arranged at the inner bottom of the protective shell. A moving wheel is arranged at the bottom of the installation plate. A sealing plate is arranged at the outer end of the installation plate. The inner side of the sealing plate is fixedly connected to the kiln bottom plate.

[0004] Adopting the above scheme, after the kiln car composed of the kiln bottom plate, the installation plate, the moving wheel, and the sealing plate is pulled out, the bottom shielding plate and the inner shielding plate can automatically block the inside of the device to avoid the diffusion of hot air inside the kiln chamber, making it more energy-efficient. However, there are certain deficiencies in the actual use of the above scheme. When the kiln bottom plate with ceramics needs to be sent into or taken out of the kiln furnace, the operator needs to push and pull the kiln car by holding the front handle of the sealing plate. When the kiln furnace completes the firing cycle and the internal temperature is extremely high, if the operator directly opens the door for handling, the operator is extremely likely to be burned due to contacting the high-temperature environment or accidentally touching high-temperature objects, which seriously threatens personal safety and there are certain deficiencies. Summary of the Utility Model

[0005] The problem to be solved by the utility model is to provide a high-temperature shuttle kiln structure that is convenient for pushing and pulling the kiln car, improves personal safety, and saves labor.

A bearing assembly is arranged inside the furnace body. A placing rack is arranged inside the furnace body. A sealing door is arranged at the front side of the furnace body. A group of supporting wheels are fixedly installed at the bottom of the sealing door. An adjusting mechanism is arranged below the furnace body. A group of guiding grooves are opened on the inner wall of the furnace body.

[0007] Preferably, for a high-temperature shuttle kiln structure as described above, the bearing assembly includes a bearing plate, and the outer surface of the bearing plate slides on the inner wall of the furnace body. Tooth grooves are formed at the bottom of the bearing plate.

[0008] Preferably, for a high-temperature shuttle kiln structure as described above, a limiting slide bar is fixedly connected to the outer surface of the bearing plate, and the outer surface of the limiting slide bar slides on the inner wall of the furnace body.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1 to 4 shown, a high-temperature shuttle kiln structure includes a furnace body 1, and a bearing assembly 2 is arranged inside the furnace body 1.

[0020] The bearing assembly 2 includes a bearing plate 201, and the outer surface of the bearing plate 201 slides on the inner wall of the furnace body 1. Tooth grooves 202 are formed at the bottom of the bearing plate 201.

[0021] The outer surface of the bearing plate 201 is fixedly connected with a limiting slide bar 203, and the outer surface of the limiting slide bar 203 slides on the inner wall of the furnace body 1.

[0022] The limiting slide bar 203 is T-shaped and can be engaged with the T-shaped groove formed on the inner side wall of the furnace body 1. During the movement, the limiting slide bar 203 can limit the bearing plate 201 and ensure the stability of the bearing assembly 2 during the movement.

[0023] A set of guide grooves 7 are formed on the inner wall of the furnace body 1. Guide wheels 204 are rotatably connected to the inner wall of the bearing plate 201, and the guide wheels 204 roll in the guide grooves 7.

[0024] An activity groove is formed at the bottom of the bearing plate 201, and the guide wheels 204 are installed inside the activity groove. The guide wheels 204 can roll in the guide grooves 7, and the guide wheels 204 can play a supporting and guiding role for the bearing plate 201.

[0025] A placing rack 3 is arranged inside the furnace body 1.

[0026] The placing rack 3 is a multi-layer rack body, and ceramic products can be placed on each layer. Before firing, the placing rack 3 needs to be connected to the bearing plate 201 through fixing parts to prevent damage to the ceramic products caused by the displacement of the placing rack 3 when entering and leaving the furnace body 1.

[0027] A sealing door 4 is provided on the front side of the furnace body 1.

[0028] An observation window is provided on the sealing door 4, which is convenient for observing the firing condition of the ceramic products inside the furnace body 1 in real time.

[0029] A set of support wheels 5 are fixedly installed at the bottom of the sealing door 4.

[0030] The support wheels 5 can support the sealing door 4, so that the sealing door 4 can always maintain the same horizontal line with the bearing assembly 2 during the moving process, thereby increasing the stability of the bearing assembly 2 and the placement rack 3 during the moving process, and avoiding the ceramic products on the placement rack 3 from being damaged due to violent shaking.

[0031] An adjusting mechanism 6 is provided below the furnace body 1.

[0032] The adjusting mechanism 6 includes a fixing plate 601, and the outer surface of the fixing plate 601 is fixedly connected to the bottom of the furnace body 1, and a motor 602 is fixedly installed on the outer surface of the fixing plate 601.

[0033] The output end of the motor 602 is fixedly connected to a rotating shaft 603, and the outer surface of the rotating shaft 603 is rotatable with the inner wall of the fixing plate 601. One end of the rotating shaft 603 away from the motor 602 is fixedly connected to a gear 604, and the gear 604 meshes with the tooth groove 202.

[0034] The outer surface of the rotating shaft 603 is rotatably connected to a protective shell 605, and the outer surface of the protective shell 605 is fixedly connected to the bottom of the furnace body 1.

[0035] When the motor 602 is started, the motor 602 will drive the rotating shaft 603 to rotate, and then the rotating shaft 603 will drive the gear 604 to rotate accordingly. Since the gear 604 meshes with the tooth groove 202, it can drive the bearing plate 201 to gradually move outwards from the inside of the furnace body 1, and then drive the placement rack 3 and the support wheels 5 to move accordingly, so as to facilitate pushing the placement rack 3 into the furnace body 1 and pulling it out of the furnace body 1, avoiding the operator from pushing and pulling the kiln car in person, and avoiding the operator from contacting the high-temperature environment or accidentally touching high-temperature objects and being burned, effectively ensuring the personal safety of the operators.

[0036] Working principle: When in use of the present utility model, when it is necessary to take out the ceramics on the placement rack 3 from the inside of the furnace body 1, only need to turn on the motor 602 through an external controller. At this time, the motor 602 will drive the rotating shaft 603 to rotate, and then the rotating shaft 603 will drive the gear 604 to rotate accordingly. Since the gear 604 meshes with the tooth groove 202, it can drive the bearing plate 201 to gradually move outwards from the inside of the furnace body 1. During the moving process, the limit slide bar 203 can limit the bearing plate 201, ensuring the stability of the bearing assembly 2 during the moving process. At this time, the guide wheel 204 rolls in the guide groove 7, and at the same time, the limit slide bar 203 and the guide wheel 204 can support and guide the bearing plate 201. During the movement of the bearing assembly 2, it will drive the placement rack 3, the sealing door 4 and the support wheel 5 to move accordingly. At this time, the support wheel 5 can support the sealing door 4, and can also increase the stability of the bearing assembly 2 and the placement rack 3 during the moving process, preventing the ceramics on the placement rack 3 from shaking violently and being damaged. Thus, it is convenient to push the placement rack 3 into the furnace body 1 and pull it out of the furnace body 1. When it is necessary to push the ceramics into the furnace body 1, only need to turn on the motor 602 to reverse it, and then the placement rack 3 carrying the ceramics can be quickly pushed back into the furnace body 1. When the ceramics are moved out of the furnace body 1 and pushed back into the furnace body 1 from the outside, there is no need for the operator to pull the handle in person, which saves time and effort, avoids the operator from pushing and pulling the kiln car in person, and prevents the operator from contacting the high-temperature environment or accidentally touching high-temperature objects and being burned, effectively ensuring the personal safety of the operators.
