Description

Technical Field

[0001] This invention relates to the field of kiln technology, and in particular to a kiln cooling device. Background Technology

[0002] A kiln is a device made of refractory materials used to fire products; it is an essential facility in the shaping of pottery. Humanity's tens of thousands of years of ceramic firing history have accumulated a wealth of kiln styles and experience. From open-air firing and pit firing in primitive societies to dome-shaped rising-flame round kilns, semi-downdraft horseshoe-shaped kilns, semi-slope dragon kilns, and duck-egg-shaped kilns, and then to modern indoor gas kilns and electric kilns, kiln technology has been continuously improved and developed. To accelerate the cooling rate of items inside the kiln, cooling mechanisms are added to the kiln.

[0003] Patent application number CN202222867112.X discloses a kiln cooler, including a kiln body. Air inlet pipes are installed on both sides of the bottom of the kiln body. Water is added inside the outer shell, placing the pipes underwater. Air enters the kiln body through the two air inlet pipes, is heated inside the kiln body, and then enters the outer shell through the pipes. The air is then cooled by the water, filtered by a first and second filter plate, and discharged through an exhaust pipe. However, this type of cooler only relies on airflow for cooling, resulting in low cooling efficiency and requiring a considerable amount of time to bring the product to a suitable temperature.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a kiln cooling device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a kiln cooling device, comprising a kiln body, a cooling plate fixed to the top of the kiln body, a cavity inside the cooling plate, air outlet slots on both sides of the bottom of the cooling plate, multiple air inlet pipes fixed to the top of the cooling plate, a fan fixed to the end of each air inlet pipe, multiple cooling pipes evenly fixed to the bottom of the cooling plate, one end of each cooling pipe connected to a water pump via a water inlet pipe, and the other end of each cooling pipe fixed to a water outlet pipe, a support shaft fixed to the cooling plate on one side below the air outlet slots, an air guide device provided on the support shaft, the air guide device comprising two fixed plates mounted on and rotatably connected to the support shaft, and multiple air guide plates obliquely fixed between the two fixed plates.

[0008] Preferably, the cooling pipe is S-shaped and fixed to the bottom of the cooling plate.

[0009] Preferably, multiple metal plates are evenly fixed on the cooling pipe. Through heat exchange between the metal plates and the hot air inside the kiln, the metal plates, as their temperature rises, transfer the temperature to the cooling pipe. The heat is then absorbed by the cold water inside the cooling pipe and discharged from the kiln.

[0010] Compared with existing technologies, the present invention has the following advantages:

[0011] This device uses a fan to draw in external cold air into the cooling pan. The cold air is then discharged through the air outlet. After the airflow reaches the air guide plate, the fixed plate rotates around the support shaft, causing the air guide plate to rotate. The airflow then flows along the surface of the air guide plate. Due to the rotation of the air guide plate, the airflow is distributed to various positions inside the kiln, achieving rapid mixing of the cold air with the air inside the kiln and reducing the temperature inside the kiln. In addition, a water pump draws in cold water and discharges it through the inlet pipe to the cooling pipe and then through the outlet pipe. The cold water flows in the cooling pipe and exchanges heat with the external air, rapidly reducing the temperature inside the kiln. Attached Figure Description

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 3As shown, this embodiment discloses a kiln cooling device, including a kiln body 1. A cooling plate 2 is fixed to the top of the kiln body 1. A cavity 7 is provided inside the cooling plate 2. Air outlet slots 9 are provided on both sides of the bottom of the cooling plate 2. Multiple air inlet pipes 8 are fixed to the top of the cooling plate 2. A fan is fixed to the end of each air inlet pipe 8. Multiple cooling pipes 3 are evenly fixed to the bottom of the cooling plate 2. One end of the cooling pipe 3 is connected to a water pump through a water inlet pipe 4. The other end of the cooling pipe 3 is fixed to a water outlet pipe 5. A support shaft 10 is fixed on the cooling plate 2 on one side below the air outlet slots 9. An air guide device is provided on the support shaft 10. The air guide device includes two fixed plates 11 that are set on the support shaft 10 and rotatably connected to the support shaft 10. Multiple air guide plates 12 are obliquely fixed between the two fixed plates 11. The product to be fired is placed inside the kiln body 1. After sealing the kiln body 1, the electric heating tubes inside the kiln body 1 are powered on. Once the electric heating tubes are turned on, they heat the inside of the kiln body 1. After the product is fired, the kiln door on the kiln body 1 is opened. Then, the cold air from outside is exhausted into the cooling plate 2 by a fan. The cold air is discharged through the air outlet 9. After the airflow reaches the air guide plate 12, the air guide plate 12 drives the fixed plate 11 to rotate because the fixed plate 11 is rotatably connected to the support shaft 10. Each air guide plate 12 rotates around the support shaft 10. After the airflow reaches the position of the air guide plate 12, it flows along the surface of the air guide plate 12. Due to the rotation of the air guide plate 12, the airflow is blown to various positions inside the kiln body 1, realizing the rapid mixing of cold air with the air inside the kiln body 1, reducing the temperature inside the kiln body 1. The water pump draws cold water and discharges it to the cooling pipe 3 through the water inlet pipe 4, and then discharges it through the water outlet pipe 5. As the cold water flows in the cooling pipe 3, the cold water exchanges heat with the outside air, rapidly reducing the temperature inside the kiln body 1.

[0020] Example 2:

[0021] This embodiment discloses a kiln cooling device. Based on the structure and principle of embodiment 1, the cooling pipe 3 in this embodiment is fixed in an S-shape at the bottom of the cooling plate 2.

[0022] Multiple metal plates 6 are evenly fixed on the cooling pipe 3. The metal plates 6 exchange heat with the hot air inside the kiln body 1. After the temperature of the metal plates 6 rises, the metal plates 6 transfer the temperature to the cooling pipe 3. The heat is absorbed by the cold water inside the cooling pipe 3 and then discharged from the kiln body 1.

[0023] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
