The sealing assembly 3 comprises a sealing cover 31, the sealing cover 31 is provided with two hinges 32, and the sealing cover 31 is rotationally connected with a connecting plate 33 through the hinges 32. The connecting plate 33 is fixedly connected with a handle 34 for facilitating the pulling of the staff.

[0024] As one preferred technical scheme in the embodiment: in use, when the sintered raw materials need to be taken out from the sliding table 12, the staff can first control the support plate 21 to displace to the sealing cover 31, at this time, in the displacement process of the support plate 21, the transverse sealing plate 26 is displaced with the support plate 21 to achieve the sealing effect of the bottom of the combustion chamber 11, and in the displacement process of the support plate 21, the vertical sealing plate 25 can always keep in contact with the inner wall of the combustion chamber 11, thereby effectively preventing the heat in the sliding table 12 from escaping into the air, and in the continuous displacement process of the support plate 21, when the vertical sealing plate 25 on the right side of the support plate 21 is just displaced to the mouth of the combustion chamber 11, the staff can control the pull handle 34 to rotate the connecting plate 33, and then take out the sintered raw materials on the support plate 21.

[0025] The technical effects of the above technical scheme are as follows:

[0026] By setting the sealing cover 31, the heat in the combustion chamber 11 can be effectively prevented from escaping into the air during the taking process, so that the combustion chamber 11 still has a high temperature when the next batch of products needs to be sent into the combustion chamber 11 for sintering, thereby effectively reducing the time needed to heat the combustion chamber 11 to the preset temperature and effectively reducing the energy loss.

[0027] Embodiment two:

[0028] Please refer to Figure 5 In order to limit the connecting plate 33 and facilitate the staff to take materials, the kiln body 1 in the embodiment is provided with a limiting assembly 4 for limiting the connecting plate 33.

[0029] As one preferred technical solution in the embodiment: in actual use, when the staff needs to pull the connecting plate 33 to take out the raw materials on the top of the supporting plate 21, the connecting plate 33 will first contact the circular limiting table 42 when it is displaced upward during the pulling process, so that the circular limiting table 42 is displaced horizontally, which can drive the slide rod 41 and the mounting plate 43 to be displaced horizontally during the displacement of the circular limiting table 42, and the mounting plate 43 can drive the return spring 44 to be stretched and stored energy during the displacement of the mounting plate 43. When the connecting plate 33 is displaced above the circular limiting table 42, the slide rod 41 will be reset under the action of the mounting plate 43, thereby driving the circular limiting table 42 to be displaced to limit the connecting plate 33, and the staff can take out the materials at this time.

[0030] It is worth noting that the stiffness coefficient of the return spring 44 in the embodiment can ensure that the circular limiting table 42 can support the connecting plate 33 when the connecting plate 33 is not subjected to external force.

[0031] The above technical solution has the following technical effects: the circular limiting table 42 can effectively support and limit the connecting plate 33 during use, which facilitates the staff to take out the materials, and the return spring 44 can effectively provide a supporting force for the circular limiting table 42 and reset the circular limiting table 42 during use.

[0032] The working principle of the above embodiment is as follows:

[0033] I. In use, when the staff needs to take out the sintered raw materials from the sliding table 12, the staff can first control the supporting plate 21 to be displaced to the sealing cover 31, so that the horizontal sealing plate 26 is displaced with the supporting plate 21 to seal the bottom of the combustion chamber 11 during the displacement of the supporting plate 21, and the vertical sealing plate 25 can always be in close contact with the inner wall of the combustion chamber 11 during the displacement of the supporting plate 21, thereby effectively preventing the heat in the sliding table 12 from being dissipated into the air. During the continuous displacement of the supporting plate 21, when the vertical sealing plate 25 on the right side of the supporting plate 21 is just displaced to the mouth of the combustion chamber 11, the staff can control the pulling handle 34 to rotate the connecting plate 33, and then take out the sintered raw materials on the supporting plate 21.

[0034] II. In actual use, when the worker needs to pull the connecting plate 33 to take out the raw materials on the top of the supporting plate 21, the connecting plate 33 will first contact the circular limiting table 42 when being pulled upward, so that the circular limiting table 42 is horizontally displaced, and the sliding rod 41 and the mounting plate 43 are horizontally displaced in the process of displacement of the circular limiting table 42, and the mounting plate 43 is stretched to store energy in the process of displacement, and when the connecting plate 33 is displaced above the circular limiting table 42, the sliding rod 41 is reset under the action of the mounting plate 43, so that the circular limiting table 42 is displaced to limit the connecting plate 33, and the worker can take out the materials.
