Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-5 As shown, a high-efficiency and energy-saving ceramic firing kiln includes an electric kiln body 100 and a firing rack 200 disposed inside the electric kiln body 100 for placing ceramics. A heat preservation section 400 is provided on the top of the electric kiln body 100. A pulling part 300 is installed between the firing rack 200 and the cabinet door of the electric kiln body 100. The pulling part 300 includes an arc-shaped groove 310 formed at the bottom of the firing rack 200. A slider 330 is slidably connected inside the arc-shaped groove 310. A pulling plate 320, which has an arc-shaped structure, is fixed to the inner side of the cabinet inside the electric kiln body 100. The top of the other end of the pulling plate 320 is fixed to the bottom of the slider 330. The firing rack 200 is connected to a limiting member 340 for blocking the slider 330. The pulling part 300 also includes moving grooves 370 on both sides and the bottom sides of the inner cavity of the electric kiln body 100. Several pulleys 350 are fixed on both sides of the bottom and the left and right sides of the firing rack 200. The other end of the pulleys 350 is rolledly connected to the inside of the moving grooves 370. The lower moving groove 370 is located behind the support rod 362. When the firing rack 200 slides, it can reduce the friction between the firing rack 200 and the inner wall of the electric kiln body 100, making it easier for the firing rack 200 to be pushed in and pulled out.

[0031] Based on the above scheme, to facilitate the application of force to the firing rack 200, the limiting member 340 includes a first sliding plate 341 and a second sliding plate 343 fixed to both sides of the surface of the firing rack 200. A limiting plate 342 slides through the interior of the first sliding plate 341. One end of the limiting plate 342 is T-shaped, and a groove 345 is formed on its surface. This design allows workers to easily push the limiting plate 342 by hand. The other end of the limiting plate 342 engages with the interior of the second sliding plate 343. A baffle 344 is fixed to the surface of the firing rack 200. Before pushing the electric kiln body 100 inside, the limiting plate 342 can be pulled to the right to remove the obstruction of the front end of the arc groove 310. Then the firing rack 200 can be pushed into the electric kiln body 100. When closing the door, after the slider 330 at one end of the pulling plate 320 enters the arc groove 310, the limiting plate 342 can be pushed to the left again to move the left end of the limiting plate 342 into the sliding plate 343, thereby obstructing the front end of the arc groove 310, so that the firing rack 200 can be pulled out when the cabinet door is opened later.

[0032] See Figure 5 To improve the stability of the firing rack 200 during movement, the pulling part 300 also includes a support member 360. The support member 360 includes movable grooves 361 formed on both sides of the bottom of the firing rack 200. A support rod 362 is hinged inside the movable grooves 361. A pulley 363 is fixedly connected to the bottom of the other end of the support rod 362. When the firing rack 200 is pushed into the electric kiln body 100, the distance between the bottom of the firing rack 200 and the bottom of the inner cavity of the electric kiln body 100 is greater than the width of the support rod 362 and the pulley 363. After rotation, the bottom of pulley 263 just contacts the ground. As the firing rack 200 is pulled outward, without the support rod 362, the support rod 362 will be downward due to the gravity of pulley 263. At this time, pulley 263 will contact the ground to improve the stability of the firing rack 200 when sliding. When the firing rack 200 is pushed into the electric kiln body 100, the support rod 362 is blocked by the electric kiln body 100, so that the movable groove 361 and pulley 263 can be screwed into the movable groove 361.

[0033] Based on the above scheme, see Figure 2To reduce energy waste, the insulation section 400 includes an outer shell 410 fixed to the top of the electric kiln body 100. The top of the outer shell 410 is connected to a liquid inlet. Before firing, water can be injected into the interior of the outer shell 410. A connecting pipe 420 is installed inside the outer shell 410. One end of the connecting pipe 420 is connected to the exhaust port at the top of the electric kiln body 100, and the other end of the connecting pipe 420 passes through the outer shell 410 and extends to its top. A drain pipe 430 with a valve control is connected to the left side of the outer shell 410. The hot air generated during the operation of the electric kiln body 100 flows into the connecting pipe 420, and the hot air in the connecting pipe 420 comes into contact with the water in the outer shell 410, thereby heating the water. The heated water can be discharged through the drain pipe 430.

[0034] Working principle: In use, the ceramic blank can be placed in the firing rack 200. After placement, the limiting plate 342 can be pulled to the right, so that the limiting plate 342 no longer obstructs the front end of the arc groove 310. Then, the firing rack 200 can be pushed into the electric kiln body 100. When closing the door, the slider 330 at one end of the pulling plate 320 will enter the arc groove 310. Then, the limiting plate 342 can be pushed to the left again, so that the left end of the limiting plate 342 enters the sliding plate 343, thereby obstructing the front end of the arc groove 310. This facilitates the subsequent pulling of the cabinet door, allowing the firing rack 200 to be pulled out. After the cabinet door is closed, The firing process is carried out through the electric kiln body 100. During the firing process, hot air enters the connecting pipe 420, which heats the water source inside the outer shell 410. The heated water source can be discharged through the drain pipe 430. After firing, the cabinet door can be opened. As the cabinet door is opened, the slider 330 will move forward inside the arc groove 310. When it reaches the front end, it will contact the limiting plate 342. Due to the obstruction of the limiting plate 342, the firing rack 200 can be pulled out. The firing rack 200 pulled out can not only accelerate the cooling speed in the outside, but also avoid the risk of burns caused by manual pulling.
