Description

Technical Field

[0001] This utility model relates to the field of kiln technology, specifically a vertical kiln for ceramic firing. Background Technology

[0002] In the ceramic manufacturing industry, ceramic sintering is a key step that determines product quality and performance. Vertical kilns are widely used in the ceramic sintering field due to their advantages such as high efficiency and energy saving, high space utilization, and ease of automation. As an important tool for carrying ceramic blanks in and out of the kiln, the stability and safety of the kiln car directly affect the quality and production efficiency of ceramic sintering. As the basic infrastructure for the operation of the kiln car, the rationality of its design plays a decisive role in the smooth operation of the kiln car.

[0003] Currently, most traditional ceramic firing kilns use a fixed slope and single-section rail design. This design is problematic in complex installation environments. The fixed slope makes it difficult to adjust the track according to actual working conditions. When the kiln car is going uphill, an unreasonable slope can cause difficulty, while going downhill can lead to excessive sliding speed, posing significant safety hazards. Furthermore, it's difficult to precisely control the speed and position of the kiln car entering and exiting the kiln. Additionally, the single-section rail is ill-suited to complex terrain with slopes, uneven surfaces, or steps. When the ground is uneven, the rail's ground support is unstable, causing the kiln car to sway, tip over, or experience uneven stress during movement. Therefore, a vertical ceramic firing kiln is needed to address the problems existing in current technology. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical kiln for ceramic firing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vertical kiln for ceramic firing, comprising a kiln body, a kiln door rotatably connected to the inlet and outlet of the kiln body, a track mechanism provided at the inlet and outlet of the kiln body, the track mechanism comprising a first track frame and a second track frame, the first track frame rotatably connected to one end of the kiln body, the second track frame rotatably connected to one side of the first track frame, and a height adjustment screw fixed at the lower end of both the first track frame and the second track frame, the external thread of the height adjustment screw being connected to a lifting support.

[0006] Preferably, a tilting seat is fixed to one end face of the kiln body, and a tilting cam is fixed to both the front and rear surfaces of the first rail frame, the tilting cam being rotatably connected in the tilting seat.

[0007] Preferably, a first rotating base is fixed to one end face of the first rail frame and the second rail frame opposite to each other, and a second rotating base is fixed to one end face of the second rail frame and the first rail frame opposite to each other.

[0008] Preferably, a hinged rotating arm is hinged between the first rotating base and the second rotating base, and the surface of the hinged rotating arm is provided with a rotating groove.

[0009] Preferably, the upper end face of the lifting support is provided with a height adjustment screw hole, and the height adjustment screw hole of the lifting support is threaded onto the outside of the height adjustment screw.

[0010] Preferably, the inner bottom wall of the kiln body is provided with a positioning groove, and the front surface of the kiln body is fixed with an organic control panel.

[0011] This utility model provides a vertical kiln for ceramic firing, which has the following advantages compared with the prior art:

[0012] Beneficial effects:

[0013] The track mechanism allows for flexible slope adjustment, optimizing kiln car operation: by rotating the lifting support to adjust the distance between it and the first and second rail frames, the slope of the track mechanism can be flexibly adjusted. This design effectively solves the problems of kiln cars having difficulty going uphill and sliding too fast downhill, meeting the diverse slope requirements of different working conditions and improving the stability and safety of kiln cars entering and exiting the kiln body.

[0014] By setting up a first and second rail frame, which are independently adjusted for segmented tilt via lifting supports, this design can effectively handle complex terrains such as slopes, uneven surfaces, or steps. Compared to traditional single-segment rail frames, this design avoids unstable ground support caused by uneven ground, preventing swaying, tipping, or uneven force distribution when the kiln car is in motion, thus ensuring stable operation. When not in use, the hinged arm can rotate between the first and second rotating seats, allowing the second rail frame to fold vertically with the first rail frame, significantly reducing the footprint of the rail mechanism and facilitating various activities around the kiln, thereby improving the utilization efficiency of the space around the kiln.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a vertical kiln for ceramic firing, including a kiln body 1. A kiln door 3 is rotatably connected to the inlet and outlet of the kiln body 1. A track mechanism 4 is provided at the inlet and outlet of the kiln body 1. The track mechanism 4 includes a first track frame 5 and a second track frame 6. The first track frame 5 is rotatably connected to one end of the kiln body 1, and the second track frame 6 is rotatably connected to one side of the first track frame 5. The lower ends of the first track frame 5 and the second track frame 6 are both fixed with height adjustment screws 13, and the external threads of the height adjustment screws 13 are connected to lifting supports 12.

[0022] Before using the vertical kiln, the operator can rotate the lifting support 12 along the height adjustment screw 13 according to the actual working conditions to precisely adjust the distance between the lifting support 12 and the corresponding first rail frame 5 and second rail frame 6. In this way, the support height of the first rail frame 5 and the second rail frame 6 can be flexibly changed so that they can be supported on the ground at different tilt angles. This variable slope design effectively solves the problems of kiln cars having difficulty going uphill and sliding too fast downhill when facing different working conditions in traditional kilns, and provides a strong guarantee for the smooth entry and exit of kiln cars.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a rotating seat 15 is fixed to one end face of the kiln body 1, and rotating convex shafts 11 are fixed to the front and rear surfaces of the first rail frame 5. The rotating convex shafts 11 are rotatably connected in the rotating seat 15. A first rotating seat 7 is fixed to the end face of the first rail frame 5 opposite to the second rail frame 6, and a second rotating seat 8 is fixed to the end face of the second rail frame 6 opposite to the first rail frame 5. A hinged rotating arm 9 is hinged between the first rotating seat 7 and the second rotating seat 8. A rotating groove 10 is opened on the surface of the hinged rotating arm 9. A height adjustment screw hole 14 is opened on the upper end face of the lifting support 12. The height adjustment screw hole 14 of the lifting support 12 is threaded onto the outside of the height adjustment screw 13.

[0024] When the ground has complex terrain such as slopes, unevenness, or steps, the first rail frame 5 and the second rail frame 6 can achieve segmented tilt adjustment through their respective independent lifting supports 12. That is, the tilt support of the first rail frame 5 and the second rail frame 6 can be adjusted according to different ground conditions. Without affecting the normal movement of the kiln car, it perfectly matches the complex application terrain and avoids the instability of the ground support of the traditional single-section rail frame due to uneven ground, which may cause the kiln car to shake, tip over, or have uneven force when moving. This significantly improves the stability and safety of the kiln car operation.

[0025] Further as Figure 1 As shown, it is worth noting that the inner bottom wall of the kiln body 1 is provided with a positioning groove 16, and the front surface of the kiln body 1 is fixed with an organic control panel 2.

[0026] This solution has the following working process: Before use, the lifting support 12 can be rotated along the height adjustment screw 13 to adjust the distance between the lifting support 12 and the corresponding first rail frame 5 and second rail frame 6. The support height of the first rail frame 5 and the second rail frame 6 can be adjusted to facilitate support on the ground at different tilt angles. This variable slope method meets the slope requirements of different working conditions. When the kiln car enters and exits the kiln body 1, adjusting the tilt angle of the rail frame can improve the situation of the kiln car having difficulty going uphill and sliding quickly downhill.

[0027] During the tilt angle adjustment of the first rail frame 5 and the second rail frame 6, the first rail frame 5 and the second rail frame 6 can achieve segmented tilt adjustment through independent lifting supports 12, so as to match complex application terrain without affecting the movement of the kiln car. When there are slopes, bumps or steps on the ground, the tilt support of different rail frames can be adjusted to avoid the ground support of traditional single-section rail frames being unstable due to uneven ground, which would lead to swaying, tipping or uneven force when the kiln car moves. In addition, the first rail frame 5 and the second rail frame 6 are combined into a whole rail frame when in use. When idle, the hinged rotating arm 9 can rotate between the first rotating seat 7 and the second rotating seat 8, so that the second rail frame 6 can be folded up and down with the first rail frame 5, and the reduced footprint is conducive to the movement of personnel around the kiln.

[0028] After the plates and tableware have been sintered and cooled down, the kiln door 3 on the kiln body 1 is opened, and then the kiln car is pulled out. The finished plates and tableware are stored on the kiln car, which moves downhill using the first inclined rail 5 and the second inclined rail 6.
