Description

Technical Field

[0001] This utility model relates to the technical field of celadon firing equipment, specifically to a kiln device for celadon processing that provides uniform heating. Background Technology

[0002] The firing of celadon requires extremely high standards for temperature uniformity, atmosphere stability (reducing / oxidizing atmosphere), and sealing performance within the kiln. Traditional celadon kiln equipment suffers from the following key technical defects, which restrict the firing quality: Uneven temperature and poor firing quality: Traditional kilns have scattered heating wires or no zone control, resulting in large temperature differences in different areas of the kiln. This leads to uneven heating of the celadon body, inconsistent glaze color, cracking of the body, and insufficient yield. Without precise temperature feedback and adjustment, relying solely on experience for control results in poor stability. Utility Model Content

[0013] 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.

[0014] Please see Figure 1-3This utility model provides a technical solution: a kiln device for uniformly heated celadon processing, including a kiln 1. A kiln door 2 is rotatably connected to one side of the kiln 1 via a hinge. A connecting layer 3 is bolted to the inner side of the kiln 1 and the kiln door 2. Several sets of mounting grooves 4 are equidistantly arranged along the circumference inside the connecting layer 3. Heating wires 5 are fixedly connected to the mounting grooves 4 by snap-fit, realizing zoned heating. Three sets of temperature sensors 6 are equidistantly bolted to one side of the connecting layer 3 along the height direction. The lower part of one side of the kiln 1 is fixed by welding. The furnace 1 is connected to an air inlet pipe 12 for inputting carbon monoxide required for firing celadon. An annular connecting groove 13 is provided inside the lower side of the furnace 1. One end of the air inlet pipe 12 is inserted into the connecting groove 13 and is fixedly connected to a conduction pipe 14 by welding. Six sets of air outlet pipes 15 are fixedly connected to the inner side of the conduction pipe 14 at equal intervals along the circumference by welding. The other end of the air outlet pipe 15 penetrates the connecting layer 3 into the interior of the furnace 1 to achieve uniform gas distribution. A mounting bracket 7 is fixedly connected to one side of the furnace 1 by bolts, and an electrical control box 8 is fixedly connected to the other side of the mounting bracket 7 by bolts. Two sets of support blocks 10 are fixedly connected to the lower inner side of the connecting layer 3 by welding. A placement rack 11 is placed on the upper part of the support block 10 for layering celadon blanks to ensure smooth airflow around the blanks. Two sets of connecting pipes 16 are provided inside the kiln door 2 along the height direction. The connecting pipes 16 serve both to observe the firing status of celadon in real time and to exhaust air. A support pad 17 is fixedly connected to the outside of the connecting pipe 16 by adhesive bonding. A sealing sleeve 18 is fitted on the outside of the connecting pipe 16 with a gap fit. A rubber pad 19 is set between the sealing sleeve 18 and the support pad 17 to enhance the sealing effect and prevent gas leakage and temperature loss in the kiln. The control panel 9 is fixedly connected to the upper part of the electrical control box 8 by bolts. The control panel 9 integrates functions such as temperature setting, time setting, gas flow regulation, and heating zone control, realizing visual operation. Two sets of fixed brackets 20 are fixedly connected to one side of the kiln door 2 by welding. One end of the fixed bracket 20 is provided with an insertion groove 21. Two sets of rotating brackets 22 are fixedly connected to the outside of the kiln 1 by welding. A rotating shaft 23 is rotatably connected to the outside of the rotating bracket 22 by a deep groove ball bearing. An insertion rod 24 that matches the insertion groove 21 is fixedly connected to the middle of the rotating shaft 23 by welding. A threaded rod 25 is fixedly connected to the other end of the insertion rod 24 by welding. A locking handle 26 is threadedly connected to the outside of the threaded rod 25. After tightening, the kiln door 2 is tightly locked, which enhances the sealing performance.

[0015] Working principle: When using this utility model: turn on the power of the electrical control box 8, and initialize the settings through the control panel 9: set the firing temperature, firing time, duration of reducing atmosphere, and gas flow rate; place the celadon blanks in layers on the placement rack 11, and place the placement rack 11 stably on the support block 10.

[0016] Close the kiln door 2 to ensure that the kiln door fits tightly against the kiln 1; rotate the rotating shaft 23 to drive the insertion rod 24 to insert into the insertion slot 21 of the fixing frame 20; tighten the locking handle 26 to lock the kiln door 2 tightly onto the kiln 1 through the threaded transmission of the threaded rod 25, ensuring a sealing effect.

[0017] When the heating program is started, the electrical control box 8 controls the heating wires 5 of each group to be energized and heated. Three temperature sensors 6 monitor the temperature of different areas in the kiln in real time and feed it back to the electrical control box 8. If the temperature of a certain area is too low, the electrical control box 8 automatically increases the power of the heating wires 5 in the corresponding area. If the temperature is too high, the power is reduced. The gas supply program is initiated, and carbon monoxide is introduced into the kiln through the inlet pipe 12. The gas is then diverted through the conduction pipe 14 to six sets of outlet pipes 15, evenly distributed within the kiln to provide a stable reducing atmosphere for the formation of celadon glaze. The electrical control box 8 automatically adjusts the gas flow rate according to the firing stage. During firing, the changes in the celadon body and the formation of the glaze can be observed through the connecting pipe 16. When observation or venting is not required, the sealing sleeve 18 is installed, and a rubber gasket 19 is used to achieve a seal. Firing and heat preservation: After reaching the set temperature, the electrical control box 8 automatically switches to the heat preservation mode to maintain a stable temperature and ensure that the celadon body is fully sintered and the glaze is uniform.

[0018] Once the set firing time is reached, the electrical control box 8 automatically shuts off the heating wire 5 and the gas supply, and enters the natural cooling process; it is strictly forbidden to open the kiln door 2 immediately to prevent the celadon from cracking due to excessive temperature difference.
