Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a kiln cooling device. Background Art

[0002] A kiln is a device that performs heat treatment processes such as firing and smelting at high temperatures. Usually, after heat treatment of some materials using a kiln, in order to protect the structure of the materials, the kiln needs to be cooled by a cooling device. When the kiln is stopped, the kiln temperature is gradually reduced by the cooling device. At the same time, if a high-temperature kiln is not properly cooled after being shut down, it is still in a high-temperature and high-heat state and may have the risk of combustion and fire. Gradually cooling can also avoid accidents.

[0003] However, when the existing cooling device cools the kiln, it does not consider adjusting the cooling speed according to the size of the kiln, because different materials and processes require different cooling rates. Too fast cooling may cause thermal stress and cracks in the material. By adjusting the cooling rate, the product quality is guaranteed, and at the same time, the high temperature kiln is prevented from cooling down quickly, which may cause cracks on the inner wall and reduce the service life of the kiln.

[0004] Therefore, how to conveniently adjust the cooling speed of the kiln is a problem that needs to be urgently solved and optimized in the cooling device. Utility Model Content

DETAILED DESCRIPTION

[0035] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] like Figures 1 to 8 As shown, an embodiment of the utility model provides a kiln cooling device, comprising a shell 1 and a bracket 2 arranged in the shell 1, and further comprising:

[0037] A rotating part, rotatably connected to the bracket 2 and located inside the bracket 2;

[0038] A cover cloth 302 is rolled up on the rotating member to cover the area of ​​the cooling opening of the shell 1;

[0039] The other end of the cover cloth 302 is fixedly connected to the rotating member, and the cover cloth 302 is rolled up transversely in the bracket 2;

[0040] The connecting member is a rotating plate 4, which is fixed to one end of the cover cloth 302;

[0041] The limiting member is a limiting block 401, which is arranged on the back of the connecting member and located on the top of the cover cloth 302;

[0042] A fixing member, arranged on the connecting member;

[0043] The fastening member is a concealed fastening seat 404, six of which are provided and are respectively located on the housing 1, so that the fixing member is fastened and connected with at least one of the fastening members;

[0044] The six fasteners are arranged around the outside of the reserved limiting groove and are evenly distributed on the shell 1 with the cooling opening of the shell 1 as the center of the circle. The position angle of each fastener is the same as the included angle of the hollow shape on the bracket 2.

[0045] The shell 1 is provided with a reserved limiting groove, which is opened with the center of the cooling opening of the shell 1 as the axis and is arranged around the cooling opening so that the limiting member is embedded in the reserved limiting groove.

[0046] More preferably, when the user needs to adjust the cooling rate of the cooling device, the cooling rate can be adjusted by reducing or increasing the ventilation area of ​​the cooling port of the cooling device. The user can pull the fixing part out of the snap seat 404 located at the highest point to release the fixing effect of the fixing part and the snap seat 404. At this time, after the rotating plate 4 loses the restraining effect of the fixing part and the snap seat 404, it is driven by the fixing part to rotate around the center of the cooling port through the limiting effect of the limit block 401 and the reserved limiting groove. At the same time, the rotating plate 4 pulls the cover cloth 302 to extend the cover cloth 302 under the rotation support of the rotating part. When the rotating plate 4 rotates to the second snap seat 404 adjacent to the highest point, the cover cloth 302 covers one-sixth of the area of ​​the cooling port. Similarly, when the rotating plate 4 pulls the cover cloth 302 to rotate to the third snap seat 404 adjacent to the second snap seat 404, the cooling port is covered. When the rotating plate 4 pulls the cover cloth 302 to rotate to reach the fourth dark button seat 404 adjacent to the third dark button seat 404, three-sixths of the area of ​​the cooling port is covered. When the rotating plate 4 pulls the cover cloth 302 to rotate to reach the fourth dark button seat 404 adjacent to the third dark button seat 404, four-sixths of the area of ​​the cooling port is covered. When the rotating plate 4 pulls the cover cloth 302 to rotate to reach the fifth dark button seat 404 adjacent to the fourth dark button seat 404, five-sixths of the area of ​​the cooling port is covered. When the rotating plate 4 pulls the cover cloth 302 to rotate to reach the sixth dark button seat 404 adjacent to the fifth dark button seat 404, the entire area of ​​the cooling port is covered. The cooling rate is slowed down by reducing the ventilation area of ​​the cooling port. Conversely, when the rotating plate 4 pulls the cover cloth 302 to rotate in the reverse direction, the cooling port is opened, thereby increasing the ventilation area and increasing the cooling rate.

[0047] like Figures 1 to 8 As shown, the rotating part comprises:

[0048] The rotating member is a rotating rod 3, which is rotatably connected to the bracket 2;

[0049] A coil spring 301 is sleeved on the outside of the connecting member, and one end of the coil spring is fixedly connected to the rotating member, and the other end of the coil spring is fixedly connected to the connecting member;

[0050] In the embodiment of the utility model, when the cover cloth 302 is pulled by the connecting piece, the cover cloth 302 transmits the pulling force to the rotating rod 3, so that the rotating rod 3 rotates laterally inside the bracket 2, and at the same time, the rotating rod 3 stretches the coil spring 301 to extend. At this time, the cover cloth 302 is extended under the rotation support of the rotating rod 3 to cover the ventilation area of ​​the cooling passage. When the user needs to rewind the cover cloth 302 to the outside of the rotating rod 3 again, the coil spring 301 releases the energy stored by its own elastic properties, so that the cover cloth 302 is automatically rewound by the rebound force of the coil spring 301.

[0051] like Figures 1 to 8 As shown, Figures 1 to 8 As shown, the fixing member comprises:

[0052] A fixing belt 402, one end of which is fixed on the connecting member;

[0053] The positioning member is a hidden buckle 403, which is arranged on the fixing belt 402 to cooperate with the fastening member to restrain the connecting member.

[0054] In the embodiment of the utility model, the fixing belt 402 itself is soft and has a certain toughness, and can be deformed by external force, so that the hidden buckle 403 can be fastened and fixed with the fastening piece at will.

[0055] like Figures 1 to 8 As shown, a rotating member is disposed in the shell 1 , and the rotating member is rotatably connected to the bracket 2 and the inner wall of the back side of the shell 1 .

[0056] Specifically, the rotating part is a roller 201, a fan 202 is sleeved on the outer side of the roller 201, and the fan 202 is located in the shell 1, the motor driver on the fan 202 is arranged on the back side of the shell, the output end of the motor driver is fixedly connected to the roller 201 through a bearing passing through the shell 1, a ventilation pipe 101 is passed through the shell 1, a mounting plate 102 is sleeved on the outer side of the ventilation pipe 101, a rotating plate 203 is installed on the bracket 2 through the bearing, and the rotating plate 203 is fixedly connected to the rotating plate 4.

[0057] In the embodiment of the utility model, the user first fixes the mounting plate 102 to an opening at one end of the kiln, and then starts the fan 202, so that the fan 202 starts to form wind force under the support of the roller 201, and the air outside the cooling port is pumped into the ventilation pipe 101, so that the air in the ventilation pipe 101 enters the kiln through the fan 202, thereby cooling the kiln.

[0058] More preferably, the user first fixes the installation plate 102 to the opening at one end of the kiln, and then adjusts the cooling rate by reducing or increasing the ventilation area of ​​the cooling port of the cooling device according to the actual situation. The user can pull out the hidden button 403 from the hidden button seat 404 at the highest point to release the fixing effect of the hidden button 403 and the hidden button seat 404. At this time, the rotating plate 4 loses the restraining effect of the hidden button 403 and the hidden button seat 404, and the limiting effect of the limiting block 401 and the reserved limiting groove is used to rotate the rotating plate 203 with the center of the cooling port as the axis, and at the same time When the rotating plate 4 pulls the cover cloth 302, when the cover cloth 302 is pulled by the rotating plate 4, the cover cloth 302 transmits the pulling force to the rotating rod 3, so that the rotating rod 3 rotates laterally inside the bracket 2, and at the same time, the rotating rod 3 stretches the coil spring 301, and the cover cloth 302 is stretched under the rotation support of the rotating rod 3 to cover the ventilation area of ​​the cooling vent. When the rotating plate 4 rotates to the second dark buckle seat 404 adjacent to the highest point, the cover cloth 302 covers one sixth of the area of ​​the cooling vent. Similarly, when the rotating plate 4 pulls the cover cloth 302 to rotate to the second dark buckle seat 404 adjacent to the highest point, the cover cloth 302 covers one sixth of the area of ​​the cooling vent. When the rotating plate 4 pulls the cover cloth 302 to rotate to the fourth dark button seat 404 adjacent to the third dark button seat 404, it covers two-sixths of the area of ​​the cooling passage. When the rotating plate 4 pulls the cover cloth 302 to rotate to the fourth dark button seat 404 adjacent to the third dark button seat 404, it covers three-sixths of the area of ​​the cooling passage. When the rotating plate 4 pulls the cover cloth 302 to rotate to the fourth dark button seat 404 adjacent to the third dark button seat 404, it covers four-sixths of the area of ​​the cooling passage. When the rotating plate 4 pulls the cover cloth 302 to rotate to the fifth dark button seat 404 adjacent to the fourth dark button seat 404, it covers The cover covers five sixths of the area of ​​the cooling passage. When the rotating plate 4 pulls the cover cloth 302 to rotate to the sixth dark button seat 404 adjacent to the fifth dark button seat 404, the entire area of ​​the cooling passage is covered, and the cooling rate is slowed down by reducing the ventilation area of ​​the cooling passage. On the contrary, when the rotating plate 4 pulls the cover cloth 302 to rotate in the reverse direction, the cooling passage is opened, and the cover cloth 302 is automatically rolled up on the outside of the rotating rod 3 by the rebound force of the coil spring 301, so that the cover cloth 302 is stretched under the rotation support of the rotating rod 3, thereby increasing the ventilation area and the cooling rate.

[0059] Then, by starting the fan 202, the fan 202 is started under the support of the roller 201 to generate wind force, and the air outside the cooling port is pumped into the ventilation pipe 101, so that the air in the ventilation pipe 101 enters the kiln through the fan 202, thereby cooling the kiln.

[0060] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
