[0002] After the ceramic handicrafts are formed, they need to be fired in a kiln to form hard and smooth ceramics.

[0003] Due to the high temperature and long firing time required for firing, an intermittent kiln is usually used. This is a thermal equipment for intermittent production of down-draft or semi-down-draft with a kiln car as the kiln bottom. It is fired by pushing the kiln car into the kiln, and then pulled out in the opposite direction after firing to unload the fired ceramics.

[0004] In order to improve safety, it is necessary to cool down the kiln so that the operator can safely take out the ceramic handicrafts and fill in new unfired clay blanks. When firing the new unfired clay blanks, the temperature needs to be raised again.

[0005] In such a process of temperature rising and falling, the energy consumption is large, and when filling in new unfired clay blanks, the kiln is idle, resulting in low production efficiency.

[0006] Therefore, an energy-efficient ceramic handicraft firing kiln is proposed to reduce energy consumption and improve firing efficiency. Content of the Utility Model

[0007] The purpose of the utility model is to provide an energy-efficient ceramic handicraft firing kiln to solve the problems raised in the above background art.

[0008] To solve the above technical problems, the utility model provides the following technical solution: An energy-efficient ceramic handicraft firing kiln, including a firing mechanism, a sealing and supporting mechanism, and a conveying mechanism;

[0009] The conveying mechanism transmits power to the sealing and supporting mechanism, and the sealing and supporting mechanism moves horizontally inside the firing mechanism;

[0010] The firing mechanism includes a kiln body. Both sides of the kiln body are open ports. On the upper and lower sides of the inner walls of the open ports on both sides of the kiln body, sealing strips are fixedly connected. Support limit grooves are symmetrically opened on the sealing strips. A plurality of combustion nozzles are arranged inside the kiln body;

[0011] The sealing and supporting mechanism includes four horizontal guide rails. The four horizontal guide rails are symmetrically distributed in a rectangle. Sealing doors are fixedly connected to both ends and the middle of the horizontal guide rails. The sealing doors seal the open ports of the kiln body;

[0012] A support plate is fixedly connected between the sealing doors to support the ceramic handicraft;

[0013] The horizontal guide rail is translated by the transmission mechanism.

[0014] Preferably, the horizontal guide rail penetrates through the support limiting groove, and the height and width of the horizontal guide rail are equal to the height and width of the support limiting groove.

[0015] Preferably, all the sealing doors are equidistantly distributed, and the distance between the sealing doors is equal to the horizontal length of the kiln body.

[0016] Preferably, the support plate is multi-layered, and air holes are formed on each of the multi-layered support plates, and the air holes are distributed all over the support plate.

[0017] Preferably, through grooves are formed at the top of the upper horizontal guide rail and the bottom of the lower horizontal guide rail, racks are installed inside the through grooves, and the racks are meshed with the transmission mechanism.

[0018] Preferably, the transmission mechanism includes an active transmission part and a support part;

[0019] The active transmission part is installed on both sides of the bottom of the kiln body to drive the horizontal guide rail;

[0020] The support part is installed at the bottom of both sides of the kiln body to support the horizontal guide rail.

Detailed Embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1-6 , a high-efficiency and energy-saving ceramic handicraft firing kiln, including a firing mechanism 1, a sealing and supporting mechanism 2, and a transmission mechanism 3;

[0035] The transmission mechanism 3 transmits power to the sealing and supporting mechanism 2, and the sealing and supporting mechanism 2 moves left and right through the inside of the firing mechanism 1;

[0036] The firing mechanism 1 includes a kiln body 101. Both sides of the kiln body 101 are open ports. On the upper and lower sides of the inner walls of the open ports on both sides of the kiln body 101, sealing strips 102 are fixedly connected. Support limit grooves 103 are symmetrically opened on the sealing strips 102. A plurality of combustion nozzles 104 are arranged inside the kiln body 101 for heating and raising the temperature inside the kiln body 101;

[0037] The sealing and supporting mechanism 2 includes four horizontal guide rails 201. The four horizontal guide rails 201 are symmetrically distributed in a rectangle. Sealing doors 202 are fixedly connected to both ends and the middle of the horizontal guide rails 201. The sealing doors 202 seal the open ports of the kiln body 101;

[0038] A support plate 203 is fixedly connected between the sealing doors 202 to support the ceramic handicrafts;

[0039] The horizontal guide rails 201 are transmitted by the transmission mechanism 3 to achieve translation.

[0040] Through the above technical solutions, the horizontal guide rails 201 are provided, and a plurality of sealing doors 202 are fixedly connected at equal distances at both ends and the middle of the horizontal guide rails 201. A support plate 203 is fixedly connected between the sealing doors 202 to support the ceramic handicrafts. The sealing doors 202 seal both ends of the kiln body 101. After the ceramic handicrafts are fired, the transmission mechanism 3 drives the horizontal guide rails 201 to translate, so that the fired ceramic handicrafts are transmitted out of the inside of the kiln body 101, and new ceramic blanks are transmitted into the inside of the kiln body 101 for firing. The inside of the kiln body 101 does not need to be cooled during the whole process, achieving the effect of saving energy;

[0041] The transmission mechanism 3 is provided to drive the horizontal guide rails 201 in the horizontal direction. Thus, when firing ceramic handicrafts, new ceramic blanks can be placed on the exposed air holes 205. When the firing is completed, the horizontal guide rails 201 drive the air holes 205 to translate. The fired ceramics are transmitted out of the inside of the kiln body 101, and new ceramic blanks are transmitted into the inside of the kiln body 101. After unloading the fired ceramics, new ceramic blanks can be continuously placed. By repeating the above operations, the continuity of firing is realized, and the kiln body 101 always maintains high-temperature operation, achieving the effect of improving the ceramic firing efficiency;

[0042] In order to improve safety, the sealing doors 202 are made of heat-insulating materials to reduce heat conduction. Thus, when the sealing doors 202 are outside the kiln body 101, the heat conduction to the external support plate 203 is reduced, and the safety during placing the ceramic handicraft blanks and unloading is improved;

[0043] The specific working steps are as follows:

[0044] Place the ceramic handicraft blank on the air holes 205, and convey the blank to the inside of the kiln body 101 through the conveying mechanism 3 for firing;

[0045] During the firing process, continue to place the ceramic handicraft blanks on the air holes 205 exposed outside the kiln body 101;

[0046] When the first batch of ceramic handicraft blanks are fired, the horizontal guide rail 201 is towed through the conveying mechanism 3, so that the fired ceramic handicrafts are conveyed out of the inside of the kiln body 101, and the unfired ceramic handicraft blanks are conveyed into the inside of the kiln body 101 for firing;

[0047] Unload the conveyed ceramic handicrafts, and then continue to place new ceramic handicraft blanks;

[0048] Repeat the above operations to achieve continuous firing, and achieve the effect that the kiln body 101 does not need to cool down and wait.

[0049] Specifically, the horizontal guide rail 201 penetrates through the support limiting groove 103, and the height and width of the horizontal guide rail 201 are equal to the height and width of the support limiting groove 103.

[0050] Through the above technical solution, the function of setting the support limiting groove 103 is to limit the horizontal guide rail 201, and cooperate with the sealing door 202 to seal the openings on both sides of the kiln body 101. The height and width of the horizontal guide rail 201 are used to reduce the gap after the horizontal guide rail 201 penetrates through the support limiting groove 103 and improve the sealing performance;

[0051] Because the sealing strip 102 is provided, in order for the sealing door 202 to pass between the sealing strips 102, gaps are left between the top and bottom of the sealing door 202 and the inner top and bottom of the kiln body 101 to improve the heat circulation inside the kiln body 101.

[0052] Specifically, all the sealing doors 202 are equidistantly distributed, and the distance between the sealing doors 202 is equal to the horizontal length of the kiln body 101.

[0053] Through the above technical solution, the purpose of the equidistantly distributed sealing doors 202 is to improve the sealing performance. During the movement of the horizontal guide rail 201, the sealing doors 202 can always seal the openings on both sides of the kiln body 101, reduce the loss of the internal temperature of the kiln body 101, and reduce energy consumption.

[0054] Specifically, the support plate 203 is multi-layered, and air holes 205 are provided on each of the multi-layered support plates 203. The air holes 205 are distributed all over the support plate 203.

[0055] Through the above technical solution, the support plate 203 is set to be multi-layered to increase the number of ceramic artworks that can be placed. The specific number of storage layers is set according to the size of the ceramic artworks.

[0056] The provided air holes 205 are used to improve the fluidity of heat and prevent the temperature inside the kiln body 101 from being uneven up and down due to the blockage of the support plate 203.

[0057] Specifically, through grooves are provided at the top of the upper horizontal guide rail 201 and the bottom of the lower horizontal guide rail 201, and a rack 204 is installed inside the through grooves. The rack 204 meshes with the transmission mechanism 3.

[0058] Through the above technical solution, the purpose of setting the rack 204 is to improve the accuracy of the transmission of the horizontal guide rail 201 by the transmission mechanism 3. If friction is used for transmission, when the number and weight of the ceramic artworks placed on the support plate 203 are large, slipping is likely to occur during the transmission process, resulting in inaccurate transmission positions.

[0059] Specifically, the transmission mechanism 3 includes an active transmission part and a support part.

[0060] The active transmission part is installed on both sides of the bottom of the kiln body 101 to drive the horizontal guide rail 201.

[0061] The support part is installed at the bottom of both sides of the kiln body 101 to support the horizontal guide rail 201.

[0062] Through the above technical solution, the active transmission part is used to directly transmit power to the horizontal guide rail 201 to ensure that the horizontal guide rail 201 can move, while the support part is used to support the horizontal guide rail 201 at the bottom, so that the entire frame can move stably.

[0063] And when the horizontal guide rail 201 moves to one side of the kiln body 101, the horizontal guide rail 201 will not tilt due to the limitation of the support limit groove 103, the active transmission part and the support part.

[0064] Specifically, the active transmission part includes a transmission motor 301 and a secondary gear 303. An active gear 302 is installed on the output shaft of the transmission motor 301. The active gear 302 meshes with the secondary gear 303. Transmission gears 304 are installed at both ends of the secondary gear 303. The transmission gears 304 mesh with the rack 204 in the upper horizontal guide rail 201.

[0065] The support part includes symmetrically installed support gears 305, and the support gears 305 are engaged with the racks 204 in the lower horizontal guide rails 201.

[0066] Through the above technical solution, the driving motor 301 provided is a servo motor to improve the accuracy during transmission, so that the sealing door 202 can always seal the opening of the kiln body 101. When the driving motor 301 works, it will drive the driving gear 302 to drive the driven gear 303, so that the transmission gear 304 rotates synchronously to push the horizontal guide rail 201 to move left or right;

[0067] The provided support gears 305 support the horizontal guide rail 201 from the bottom, so that the frictions received by the upper and lower horizontal guide rails 201 are basically the same, to improve the running stability of the horizontal guide rail 201.

[0068] During use, by providing the horizontal guide rail 201, a plurality of sealing doors 202 are fixedly arranged at equal intervals at both ends and in the middle of the horizontal guide rail 201, and a support plate 203 is fixedly connected between the sealing doors 202 to support the ceramic handicrafts. The two ends of the kiln body 101 are sealed by the sealing doors 202. After the ceramic handicrafts are fired, the transmission mechanism 3 drives the horizontal guide rail 201 to translate, so that the fired ceramic handicrafts are conveyed out of the interior of the kiln body 101, and the new ceramic blanks are conveyed into the interior of the kiln body 101 for firing. The interior of the kiln body 101 does not need to be cooled during the whole process, achieving the effect of saving energy;

[0069] By providing the transmission mechanism 3 to drive the horizontal guide rail 201 in the horizontal direction, when firing the ceramic handicrafts, new ceramic blanks can be placed on the exposed air holes 205. After firing is completed, the horizontal guide rail 201 drives the air holes 205 to translate, the fired ceramics are conveyed out of the interior of the kiln body 101, and the new ceramic blanks are conveyed into the interior of the kiln body 101. After unloading the fired ceramics, new ceramic blanks can be placed continuously. By repeating the above operations, the continuity of firing is realized, and the kiln body 101 always works at a high temperature, achieving the effect of improving the ceramic firing efficiency.

[0070] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
