[0018] Example 1
[0019] like Figure 1 and Figure 2 As shown, the ceramic firing apparatus proposed in this utility model includes a support frame 1, a firing mechanism, and a preheating mechanism. A rotating platform 5 is provided at the top of the support frame 1, and two sets of firing racks 501 are symmetrically installed on the rotating platform 5. Multiple sets of through holes are provided on the firing racks 501. The firing mechanism consists of a firing furnace body 2 located on one side of the rotating platform 5 and a protective shell 201 connected to the top of the support frame 1 via a first hydraulic rod. The protective shell 201 is positioned above the firing furnace body 2. The preheating mechanism consists of a base 4 installed on the other side of the rotating platform 5, a preheating cover 402 connected to the top of the support frame 1 via a second hydraulic rod, and a fan 601. The bottom of the base 4 is provided with... A heat dissipation vent 401 is provided, and a protective net is detachably installed between the heat dissipation vent 401 and the base 4. A buffer chamber is provided on the base 4, and the heat dissipation vent 401 is connected to the bottom of the buffer chamber. The buffer chamber is designed to facilitate the hot air to gather in the buffer chamber and then contact the bottom of the porcelain product on the firing rack 501, and then be discharged along the heat dissipation vent 401, so that the bottom of the porcelain product can also be preheated. A uniform heating chamber 403 is provided on the preheating cover 402. Multiple sets of air holes are evenly opened on the inner walls around the perimeter and the inner wall at the top of the uniform heating chamber 403. The input end of the fan 601 is connected to the protective shell 201 through a flexible hose, and the output end of the fan 601 is connected to the uniform heating chamber 403 through a flexible hose.
[0020] Furthermore, the rotating table 5 consists of a drive mechanism set at the top of the support frame 1 and a rotating frame installed at the output end of the drive mechanism. The rotating frame is driven by the drive mechanism to rotate slowly and uniformly along the horizontal direction of the support frame 1. Two sets of firing racks 501 are installed on the rotating frame.
[0021] Furthermore, grooves are provided at the top of the firing furnace body 2 and the top of the base 4. Sealing seats are provided at the bottom of the protective shell 201 and the bottom of the preheating cover 402. The sealing seats are inserted into the grooves. A clearance opening 3 is provided on one side wall of the protective shell 201 and the preheating cover 402. The clearance opening 3 is inserted into the rotating frame to improve the sealing performance of the connection between the protective shell 201 and the firing furnace body 2, and to improve the sealing performance of the connection between the preheating cover 402 and the base 4, so as to avoid hot air leakage causing waste or affecting the heating of porcelain products.
[0022] In this embodiment, the ceramic products to be fired are placed on two sets of firing racks 501. The controller starts the rotating table 5 to drive the two sets of firing racks 501 to rotate until they are above the firing furnace body 2 and the base 4, respectively. The controller starts the first hydraulic rod to drive the protective shell 201 to move down and abut against the firing furnace body 2. The controller starts the second hydraulic rod to drive the preheating cover 402 to move down and abut against the base 4. The firing furnace body 2 is started to heat and fire the ceramic products on the firing racks 501. The controller starts the fan 601 to extract the heat between the protective shell 201 and the firing furnace body 2 and transport it to the uniform heating chamber 403. The hot air flows through multiple sets of air holes towards the ceramic products on the firing racks 501. The waste heat generated during the firing of ceramic products can be recovered and used to preheat other groups of ceramic products, improving resource utilization. After the ceramic products in the firing furnace 2 have been fired, the protective shell 201 and the preheating cover 402 are returned to their initial positions. The rotating table 5 is restarted to drive the two sets of firing racks 501 to rotate, so that the set of firing racks 501 that was just fired is moved away from the firing furnace 2, making it easier to remove the fired ceramic products and place other ceramic products to be fired. Then, the rotating table 5 continues to drive the two sets of firing racks 501, so that the ceramic products on the set of firing racks 501 that have been preheated are rotated to the top of the firing furnace 2 to continue to be fired. The firing efficiency of the preheated ceramic products is higher, thus improving the firing efficiency.
[0023] Example 2
[0024] like Figures 2 to 4 As shown, the ceramic firing apparatus proposed in this utility model, compared with Embodiment 1, has a filter assembly between the fan 601 and the protective shell 201. The filter assembly includes a filter box 6 and a dust collector bag 604. The filter box 6 is installed on the top of the support frame 1. The input end of the filter box 6 is connected to the protective shell 201 through a hose. The fan 601 is installed at the output end of the filter box 6. The dust collector bag 604 is detachably installed inside the filter box 6 and near the input end of the filter box 6.
[0025] Furthermore, the filter box 6 is L-shaped, with an installation port at the top. A connecting frame 603 is installed at the open end of the dust collector bag 604, and a sealing plate 602 is installed at the top of the connecting frame 603. The sealing plate 602 is connected to the top of the filter box 6 by bolts and abuts against the installation port. The connecting frame 603 is inserted into the inner wall of the filter box 6, and a high-temperature resistant sealing gasket is provided at the connection between the connecting frame 603 and the filter box 6 to improve the sealing performance of the connection between the dust collector bag 604 and the filter box 6, so that the hot air can be fully filtered.
[0026] Furthermore, the filter box 6 is equipped with a cleaning assembly, which includes a cam 7, a slide rod 702, and a guide rod 703. The cam 7 is driven to rotate by a motor, and a protective box is provided on the outer wall of the filter box 6. The cam 7 and the motor are installed inside the protective box. The slide rod 702 is slidably connected to the filter box 6, and an arc-shaped seat 701 is installed at one end of the slide rod 702. The arc-shaped seat 701 is intermittently connected to the protruding end of the cam 7. The guide rod 703 is installed on the inner wall of the filter box 6, and a slide seat 704 is slidably connected to the guide rod 703. The bottom end of the slide seat 704 is slidably connected to the bottom end of the filter box 6. The end of the slide rod 702 away from the cam 7 abuts against the slide seat 704. A spring 705 is sleeved on the guide rod 703. One end of the spring 705 is connected to the side wall of the filter box 6, and the other end is connected to the slide seat 704. A high-temperature resistant pull rope is provided at the top of the slide seat 704, and the other end of the pull rope is connected to the dust collector bag 604 through a clip.
[0027] In this embodiment, some ceramic products may crack during firing between the protective shell 201 and the firing furnace 2. Incompletely sintered particles or surface debris will form dust. The heat between the protective shell 201 and the firing furnace 2 is drawn into the filter box 6 by the start of the fan 601, where the dust is filtered out by the dust collector bag 604. The fan 601 then transfers the heat to the uniform heating chamber 403, and finally blows it onto the ceramic products awaiting preheating on another set of firing racks 501 for preheating. This allows the dust mixed in with the hot air to be filtered and reused, preventing the ceramic products awaiting preheating from being... To reduce dust pollution and improve firing quality, open the door of filter box 6, separate the clip on the pull rope from the dust collector bag 604, and separate the sealing plate 602 from the filter box 6 to remove and clean the dust collector bag 604. Start the motor through the controller to drive the cam 7 to rotate. Under the action of the spring 705, the cam 7 is intermittently connected to the arc-shaped seat 701, which in turn pushes the slide seat 704 to reciprocate along the guide rod 703 through the slide rod 702. This causes the dust collector bag 604 to shake, thereby cleaning the dust collector bag 604 and reducing the frequency of disassembly and cleaning of the dust collector bag 604.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
