Description

Technical Field

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

[0002] A kiln is a furnace used to fire ceramic objects, sculptures, or to fuse enamel to the surface of metal objects. It is generally made of bricks and stones, and can be made into various sizes as needed. It can be operated by combustible gas, oil or electricity. The kiln is an essential facility in pottery molding. The temperature inside the chamber is measured by a pyrometer or a temperature cone, and the internal situation can be observed through a peephole. After firing, the temperature inside the kiln needs to be lowered to room temperature before cleaning and the next firing. Blowing cold air directly into the kiln will cause the inside of the kiln to crack and break due to the thermal expansion and contraction caused by sudden cooling and heating, which will affect subsequent processing and use. At present, after the kiln is fired, it is mostly left stationary to allow the temperature inside the kiln to drop to room temperature for subsequent processing and production. This will extend the firing cycle of the product and slow down the processing speed. Therefore, it is impossible to carry out rapid and continuous production and processing. It is necessary to provide a kiln cooling device to solve the above technical problems. Utility Model Content

[0003] The purpose of the utility model is to provide a cooling device for a kiln to solve the problems raised in the above background technology.

[0006] A further improvement of the technical solution of the utility model is that: at present, after the kiln is fired, it is mostly left to stand still so that the temperature inside the kiln can be reduced to room temperature for subsequent processing and production, which will prolong the firing cycle of the product and slow down the processing speed. Therefore, it is impossible to carry out rapid and continuous production and processing. In this solution, when it is necessary to quickly cool down the inside of the kiln, the staff pushes one end of the device into the inside of the kiln, and then the working motor starts to work, driving the bevel gear set to realize the rotation of the transmission rod, and the two ends of the transmission rod are respectively fixedly connected to the exhaust fan blades, and as the transmission rod rotates, the exhaust fan blades rotate synchronously The movement forms a negative pressure inside the air inlet duct, so that the hot air inside the kiln is sucked into the air inlet duct and then flows to the air outlet duct, so that the hot air inside the kiln is quickly extracted from the kiln, and the extracted hot air will flow through the air guide seat, and part of the hot air will be diverted by the air guide seat, so that the diverted hot air flows into the air outlet and is blown into the kiln again through the air outlet, which can increase the air flow inside the kiln, take away the temperature of the inner wall of the kiln, further accelerate the cooling speed of the kiln, and complete the cooling process of the kiln more quickly. In addition, the air distribution component provided on the device can better guide the diverted hot air, so as to better perform the cooling process.

[0009] The above technical solution is adopted, in which a matching ring is fixedly installed at the inner center of the fixing frame.

[0010] A further improvement of the technical solution of the utility model is that the provision of the matching ring can increase the matching degree between the transmission rod and the fixing frame, thereby increasing the rotation stability of the transmission rod.

[0011] The above technical solution is adopted, and protective nets are fixedly installed on both ends of the air outlet duct in the solution.

[0012] A further improvement of the technical solution of the utility model is that the provision of a protective net prevents impurities inside the kiln from entering the air outlet duct, thereby preventing the impurities from causing damage to the internal components of the device.

[0016] A further improvement of the technical solution of the utility model is that: when the hot air inside the kiln draws the external hot air into the interior of the air outlet duct through the exhaust fan blades and then flows into the interior of the air inlet duct, in order to increase the air supply efficiency of the device, a fan for cooperating with the exhaust fan blades is fixedly installed at the end of the air inlet duct, which can further accelerate the flow rate of the hot air, so that the hot air can be extracted from the kiln faster. The faster the wind speed, the hot air can be guided by the air guide seat and blown into the interior of the kiln again through the air outlet and the air outlet duct. Such wind is slightly cooled by the air outlet and the air inlet duct, and the temperature difference with the interior of the kiln is not large. As it is blown into the interior of the kiln again, the inner wall of the kiln can be cooled, taking away the temperature of the inner wall of the kiln, and accelerating the cooling speed of the kiln by the device.

[0017] The above technical solution is adopted, in which a base frame is fixedly installed below the reinforcement rod, and universal wheels are fixedly installed at the four corners of the lower surface of the base frame.

[0018] A further improvement of the technical solution of the utility model is that the arrangement of the base frame can support the device, and the arrangement of the universal wheels makes it convenient for the staff to push the device, making the use of the device more convenient.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a cooling device for a kiln.
