Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing, and in particular to a refractory brick cooling device. Background Technology

[0002] Tunnel kilns are one of the commonly used pieces of equipment in the production of refractory bricks. They are constructed from refractory materials, insulation materials, and building materials. Inside the tunnel kiln are transport vehicles such as kiln cars. From the kiln head to the kiln tail, the tunnel kiln can generally be divided into a preheating section, a firing section, and a cooling section. When the ceramic blanks are moved from the kiln head to the kiln tail by the kiln cars, the blanks pass through the preheating section and the firing section in sequence to complete sintering. Finally, they are cooled in the cooling section to obtain the finished product. Because the temperature of the refractory bricks is relatively high when they leave the tunnel kiln, the unloading is slow. Therefore, a cooling section is usually set at the tail of the tunnel kiln.

[0003] A search revealed Chinese Patent Publication No. CN221666588U, which discloses a rapid cooling device for a refractory brick tunnel kiln. The device includes a cooling section. The side and top walls of the cooling section have first ventilation holes facing the firing section. An intermediate heat dissipation wall is arranged inside the cooling section along the inlet / outlet direction. A top track for supporting the kiln car is provided at the top of the intermediate heat dissipation wall. Second ventilation holes are vertically upward on both sides of the top track. Fourth ventilation holes facing the firing section are provided on both sides of the intermediate heat dissipation wall. The inner and top walls of the cooling section are constructed of heat-dissipating refractory bricks. Air inlets are opened inside the heat-dissipating refractory bricks along the inlet / outlet direction of the cooling section. First ventilation holes are opened on the inner wall surface of the heat-dissipating refractory bricks, and these first ventilation holes communicate with the air inlets.

[0004] In existing technologies, most cooling air is discharged directly through ventilation holes, resulting in a short contact time between the refractory bricks and the air, which limits the cooling effect. Utility Model Content

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A refractory brick cooling device is applied to the body of a tunnel kiln. The tunnel kiln body is equipped with a conveying assembly.

The connecting pipes extend into the tunnel kiln body. An air outlet assembly is provided at the end of the connecting pipe. The air outlet assembly includes an installation head rotatably connected to the end of the connecting pipe. Several air outlet pipes are fixedly connected to the outer wall of the installation head.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a refractory brick cooling device is applied to the tunnel kiln body 1. The inner wall and top wall of the cooling section of the tunnel kiln body 1 are both made of heat-dissipating refractory bricks. A conveying assembly is provided inside the tunnel kiln body 1. The conveying assembly includes a track 101 set on the bottom wall of the tunnel kiln body 1. A kiln car 102 is slidably connected on the track 101. The kiln car 102 is used to convey refractory bricks.

[0026] Ventilation ducts 201 are provided inside the side wall of the tunnel kiln body 1. Several connecting pipes 202 connected to the ventilation ducts 201 are pre-embedded in the inner wall of the tunnel kiln body 1. The connecting pipes 202 extend into the tunnel kiln body 1.

[0027] An air outlet assembly is provided at the end of the connecting pipe 202. The air outlet assembly includes a mounting head 203 rotatably connected to the end of the connecting pipe 202. Several air outlet pipes 204 are fixedly connected to the outer wall of the mounting head 203. The mounting head 203 is hollow inside and communicates with the connecting pipe 202.

[0028] The mounting head 203 is equipped with a power assembly, which drives the mounting head 203 to rotate the air outlet pipe 204. The power assembly includes a mounting shaft 301 fixedly connected to the inner wall of the mounting head 203. Several circumferentially arranged fan blades 302 are fixedly connected to the mounting shaft 301. The fan blades 302 are driven by wind power to rotate the mounting shaft 301, and the mounting shaft 301 drives the mounting head 203 to rotate the air outlet pipe 204, thereby turbulenting the gas inside the tunnel kiln body 1.

[0029] An exhaust duct 401 is provided inside the top wall of the tunnel kiln body 1. Several air inlet pipes 402 connected to the exhaust duct 401 are fixedly connected to the inner top wall of the tunnel kiln body 1. Baffles 403 are fixedly connected to the inner walls on both sides of the tunnel kiln body 1. The baffles 403 are located above the mounting head 203. Through the blocking effect of the baffles 403, the air blown out of the exhaust pipe 204 is directed as much as possible into the kiln car 102, thereby improving the uniformity of cooling.

[0030] Both ventilation duct 201 and exhaust duct 401 are connected to an external air source. Air is blown into the tunnel kiln body 1 through ventilation duct 201, and the gas inside the tunnel kiln body 1 enters the exhaust duct 401 through air inlet pipe 402.

[0031] Working principle: During use, the fired refractory bricks are transported by the kiln car 102. When the refractory bricks are transported to the cold cutting section at the kiln tail of the kiln car 102, air is blown into the ventilation duct 201 by an external air source. Then, the air force drives the fan blades 302 to rotate the mounting shaft 301. The mounting shaft 301 is fixedly installed on the mounting head 203, thereby driving the mounting head 203 to rotate. The mounting head 203 drives the air outlet duct 204 to rotate, which turbulents the gas in the tunnel kiln body 1, increases the contact time between the gas and the refractory bricks, and improves the cooling effect. At the same time, under the action of the external air source, the hotter gas in the tunnel kiln body 1 is extracted through the air inlet duct 402 and the exhaust duct 401, which increases the gas flow speed in the tunnel kiln body 1. Through the blocking effect of the baffle 403, the air blown out of the air outlet duct 204 is directed as much as possible into the kiln car 102, improving the uniformity of cooling.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
