Description

Technical Field

[0001] This invention relates to the field of roller kiln technology, and particularly to a roller kiln. Background Technology

[0002] A roller kiln is an industrial kiln used for firing ceramics, bricks, tiles, and other materials. It includes a preheating and sintering section and a cooling section. Since the materials need to be slowly cooled to release stress after being sintered at high temperatures, a long cooling section is required. A long cooling section increases the difficulty of site selection and limits the application of the equipment. Therefore, multiple cooling sections are set up side by side, and the materials sintered in the preheating and sintering section are transported to multiple cooling sections for cooling through transfer equipment.

[0003] Patent application number 201710837236.4 discloses a roller kiln, which includes a heating zone and multiple annealing zones. The heating zone is equipped with a heating track, and each annealing zone has an annealing track connected to the heating track. Ceramic raw materials are placed on the heating track. After being heated in the heating zone, the ceramic raw materials are transferred via the heating track to the multiple annealing tracks and cooled in each of the multiple annealing zones. The roller kiln includes a conveying device connecting the heating track and the multiple annealing tracks. The conveying device transfers the ceramic raw materials on the heating track to the multiple annealing tracks. The conveying device includes multiple transfer cars, which transfer the ceramic raw materials from the heating roller to the multiple annealing tracks. The conveying device consists of a heat-insulating track and a heat-insulating furnace fixed to the heat-insulating roller. In this roller kiln conveying device, multiple transfer cars are configured on the heat-insulating track, and each transfer car is connected to a heating track. The heat-insulating track is inclined, and the transfer cars need to turn during movement, increasing the difficulty of controlling the movement of the transfer cars. Summary of the Invention

[0038] Please see Figure 1 and Figure 2According to an embodiment of the present invention, a roller kiln includes a kiln chamber 100 and a transfer device 200. The kiln chamber 100 includes a preheating sintering section 110, a transfer zone 120, and multiple cooling sections 130. The preheating sintering section 110, the transfer zone 120, and the multiple cooling sections 130 are arranged sequentially along the length direction of the kiln chamber 100. The multiple cooling sections 130 are spaced apart along the width direction of the kiln chamber 100 and are arranged in parallel. The transfer zone 120 is sequentially divided into a sintering docking zone 121, a transport zone 122, and a cooling docking zone 123 along the length direction of the kiln chamber 100. The transfer device 200 includes a first transfer component 210, a second transfer component 220, and a third transfer component 230. The first transfer component 210 is slidably connected to the sintering docking zone 121 along the width direction of the kiln chamber 100. The second transfer component 220 is slidably connected to the cooling docking zone 123 along the width direction of the kiln chamber 100. The third transfer component 230 moves along the length direction of the kiln chamber 100. The tops of the first transfer component 210 and the second transfer component 220 are flush with the transport zone 122. The first transfer component 210 and the second transfer component 220 are used to drive the third transfer component 230 to move along the width direction of the kiln chamber 100. The third transfer component 230 is used to transport the material sintered in the preheating sintering section 110 to the cooling section 130 for cooling.

[0039] By setting up a transfer zone 120, materials from the preheating sintering section 110 are fed into multiple parallel cooling sections 130, greatly shortening the length of the original cooling section 130 and reducing the equipment's footprint requirements. This improves the equipment's adaptability without reducing output. The first transfer component 210 and the second transfer component 220 can drive the third transfer component 230 to move along the width of the kiln chamber 100. The third transfer component 230 only transports materials along the length of the kiln chamber 100, making movement control easy.

[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3The transfer device 200 also includes a traction component 300, which connects the first transfer component 210 and the second transfer component 220. The first transfer component 210 drives the second transfer component 220 to move synchronously through the traction component 300. The center line connecting the first transfer component 210 and the second transfer component 220 is aligned with the length of the kiln chamber 100. Only a power mechanism needs to be provided for the first transfer component 210. This power mechanism drives the first traction component 300 to move, which in turn drives the second transfer component 220 to move synchronously. Furthermore, the center line connecting the first transfer component 210 and the second transfer component 220 is always aligned with the length of the kiln chamber 100, facilitating the control of the corresponding positions of the first transfer component 210 and the second transfer component 220. This ensures that the third transfer component 230 can move smoothly along the length of the kiln chamber 100 between the first transfer component 210, the transport area 122, and the second transfer component 220.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The traction assembly 300 includes a traction rope 310, a first traction pulley 320, and a second traction pulley 330. The first traction pulley 320 and the second traction pulley 330 are respectively located at both ends of the transfer area 120 along the width direction of the kiln chamber 100. The middle part of the traction rope 310 is wrapped around the first traction pulley 320 and the second traction pulley 330. The two ends of the traction rope 310 are respectively connected to the first transfer assembly 210 and the second transfer assembly 220. The first transfer assembly 210 moves along the width direction of the kiln chamber 100, and the second transfer assembly 220 moves synchronously by pulling the traction rope 310. This facilitates the control of the corresponding positions of the first transfer assembly 210 and the second transfer assembly 220, and ensures that the third transfer assembly 230 can move smoothly between the first transfer assembly 210, the transport area 122, and the second transfer assembly 220 along the length direction of the kiln chamber 100.

[0042] In some embodiments, see Figure 1 and Figure 2The first transfer component 210 includes a first movable base 211, the second transfer component 220 includes a second movable base 221, and the third transfer component 230 includes a first transfer cart 231. The first movable base 211 and the second movable base 221 drive the first transfer cart 231 to move along the width of the kiln chamber 100. The first transfer cart 231 moves along the length of the kiln chamber 100. The first transfer cart 231 transports the material sintered in the preheating sintering section 110 to the cooling section 130 for cooling. The first movable base 211 drives the first transfer cart 231 to move along the width of the kiln chamber 100, facilitating docking of the first transfer cart 231 with the preset sintering section. The second movable base 221 can also drive the first transfer cart 231 to move along the width of the kiln chamber 100, facilitating docking of the first transfer cart 231 with the cooling zone. The first transfer cart 231 moves along the length of the kiln chamber 100 without turning, ensuring stable material transport and preventing it from falling off. Setting up a first transfer vehicle 231 to meet the material transportation needs of multiple cooling zones can save costs.

[0043] In some embodiments, see Figure 4 and Figure 5 The first transfer assembly 210 further includes a third movable base 212, the second transfer assembly 220 further includes a fourth movable base 222, and the third transfer assembly 230 further includes a second transfer cart 232. The third movable base 212 and the fourth movable base 222 are used to drive the second transfer cart 232 to move along the width direction of the kiln chamber 100. The movement direction of the second transfer cart 232 is the length direction of the kiln chamber 100. The second transfer cart 232 is used to transport the material sintered in the preheating sintering section 110 to the cooling section 130 for cooling.

[0044] The first transfer component 210 includes a first movable base 211 and a third movable base 212; the second transfer component 220 includes two movable bases and a fourth movable base 222; and the third transfer component 230 includes a first transfer vehicle 231 and a second transfer vehicle 232. The first transfer vehicle 231 and the second transfer vehicle 232 can alternately load and unload materials, which can improve material transportation efficiency.

[0045] The first moving base 211 moves the first transfer car 231 to the preheating sintering section 110, where it docks with the section and loads the sintered material. The second transfer car 232 is positioned on the third moving base 212 and awaits loading. After loading, the first moving base 211 moves the first transfer car 231 away from the second moving base 221, and the third moving base 212 moves the second transfer car 232 to the preheating sintering section 110, where it docks with the section and loads the material. The first transfer car 231 moves from the first moving base 211 to the transport area 122, and then to the second moving base 221. The first transfer car 231 docks with the cooling section 130 to unload material; after the second transfer car 232 finishes loading material, the third moving base 212 drives the second transfer car 232 to move away from the first moving base 211; after the first transfer car 231 finishes unloading material, the first moving base 211 moves to the preheating sintering section 110, and the second moving base 221 drives the first transfer car 231 to move to the position corresponding to the first moving base 211. The first transfer car 231 docks with the preheating sintering section 110 to load material, and the first transfer car 231 moves from the second moving base 221 to the transport area 122, and then moves to the first moving base 211. The first transfer car 231 docks with the preheating sintering section 110 to load material.

[0046] In some embodiments, see Figure 4 and Figure 5 There are two cooling sections 130, namely the first cooling section 131 and the second cooling section 132. The first transfer car 231 is used to transport the material sintered in the preheating sintering section 110 to the first cooling section 131 for cooling, and the second transfer car 232 is used to transport the material sintered in the preheating sintering section 110 to the second cooling section 132 for cooling. When the first moving base 211 moves the first transfer car 231 to the preheating sintering section 110, the fourth moving base 222 moves to the position of the second cooling section 132. When the third moving base 212 moves the second transfer car 232 to the preheating sintering section 110, the second moving base 221 moves to the position of the first cooling section 131. The first cooling section 131 corresponds to the first movable base 211, the second movable base 221 and the first transfer vehicle 231, and the second cooling section 132 corresponds to the third movable base 212, the fourth movable base 222 and the second transfer vehicle 232, which facilitates the control of the transportation process of the transfer device 200.

[0047] In some embodiments, see Figure 4 and Figure 5The first movable base 211 and the third movable base 212 are connected by the first connector 2111, and the second movable base 221 and the fourth movable base 222 are connected by the second connector 2211. The interval between the first movable base 211 and the third movable base 212 is the same as the interval between the first cooling section 131 and the second cooling section 132, and the interval between the second movable base 221 and the fourth movable base 222 is the same as the interval between the first cooling section 131 and the second cooling section 132. The first movable base 211 and the third movable base 212 are bound together by the first connector 2111, and the second movable base 221 and the fourth movable base 222 are bound together by the second connector 2211. When the first movable base 211 moves the first transfer car 231 to the preheating sintering section 110, the fourth movable base 222 moves to the position of the second cooling section 132. When the third moving base 212 moves the second transfer car 232 to the preheating sintering section 110, the second moving base 221 moves to the first cooling section 131, which facilitates the control of the transportation process of the transfer device 200.

[0048] In some embodiments, see Figure 2 , Figure 6 and Figure 7 A first track 1211 is provided in the sintering docking zone 121 for sliding connection of the first movable base 211. A second track 1231 is provided in the cooling docking zone 123 for sliding connection of the second movable base 221. The first track 1211 and the second track 1231 are guided along the width direction of the kiln chamber 100. The first track 1211 ensures that the first movable base 211 moves smoothly along the width direction of the kiln chamber 100; the second track 1231 ensures that the second movable base 221 moves smoothly along the width direction of the kiln chamber 100.

[0049] A third track 2112 is provided on the first movable base 211 for sliding connection of the first transfer carriage 231. A fourth track 1221 is provided in the transport area 122 for sliding connection of the first transfer carriage 231. A fifth track 2212 is provided on the second movable base 221 for sliding connection of the first transfer carriage 231. The guides of the third track 2112, fourth track 1221, and fifth track 2212 are along the length of the kiln chamber 100. The third track 2112, fourth track 1221, and fifth track 2212 ensure that the first transfer carriage 231 moves along the length of the kiln chamber 100 and ensures that the movement of the first transfer carriage 231 is smooth.

[0050] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The first transfer vehicle 231 includes a frame 233, a drive unit, wheels 234, and a transport roller 235. The transport roller 235 is located above the frame 233, and the wheels 234 are rotatably connected to the bottom of the frame 233. The drive unit is connected to the wheels 234 for transmission, and the drive unit drives the wheels 234 to rotate. The wheels 234 can move on the third track 2112, the fourth track 1221, and the fifth track 2212. The material sintered in the preheating sintering section 110 can be moved onto the transport roller 235, and the drive unit drives the wheels 234 to rotate, thereby moving the first transfer vehicle 231.

[0051] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The third track 2112 includes two parallel guide rails. The traveling wheel 234 has an annular protrusion 2341. The traveling wheel 234 abuts against the top of the guide rail, and the annular protrusion 2341 abuts against the inner side of the guide rail. The annular protrusion 2341 on the traveling wheel 234 abuts against the inner side of the guide rail, which can improve the movement stability of the first transfer car 231 and reduce the risk of the first transfer car 231 derailing.
