Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to an air cooling device for refractory material processing. Background Art

[0002] Refractory bricks are commonly used refractory materials. Because refractory bricks need to be fired when they are produced, and firing cannot be separated from high temperature, when the temperature reaches a certain level, it is necessary to cool down. If natural cooling is used, the cooling speed is slow, which affects the needs of subsequent firing. Therefore, additional cooling methods are usually used to achieve the purpose of quickly cooling the refractory bricks in a short time, while reducing damage to the bricks. When cooling refractory bricks, blast cooling is usually used for cooling. However, the blast cooling method has the following problems: on the one hand, the residence time of the input cooling gas is short, and the cooling gas is discharged without sufficient heat exchange with the refractory bricks. The heat is difficult to be carried out and needs continuous wind input, which causes energy waste to a certain extent; on the other hand, blast cooling is used for cooling. The cooling gas is directly blown to the surface of the brick body. Poor temperature control can easily lead to cracks on the surface of the brick, resulting in an increase in the scrap rate of the brick and excessive waste of materials. Utility Model Content

[0003] The purpose of the utility model is to provide an air cooling device for refractory material processing, which can effectively improve the cooling efficiency and enhance the temperature reduction effect, while avoiding the problem of increased brick scrap rate caused by direct blowing of cooling gas. The structure is simple and practical.

[0006] Preferably, a guide tube communicating with the air hole is obliquely provided on the outside of the cooling air duct.

[0007] Preferably, a circulating cooling pipe is provided on the top of the cooling air duct on each side, wherein two of the circulating cooling pipes are conductively connected, and the two cooling air ducts are conductively connected through the circulating cooling pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can extend the flow path of the cooling air flow inside the shell and increase the time of the cooling gas inside the shell by symmetrically arranging the cooling air ducts on the side walls of the shell, so that it can fully exchange the heat dissipated by the bricks inside the shell, ensuring the cooling effect while reducing energy loss; the wind holes inclined in opposite directions on the opposite sides of the two cooling air ducts are conducive to the convection of the gases discharged on both sides, forming a vortex airflow, pushing the hot air in the middle bricks to rise, and dissipating it through the heat sink, thereby enhancing the heat dissipation effect; in addition, the inclined arrangement of the wind holes also avoids the adverse effects of the cooling gas directly blowing on the refractory bricks, thereby reducing the scrap rate.

[0019] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0020] like Figures 1 to 3As shown, the utility model of an air cooling device for refractory material processing comprises a shell 1 with two ends connected, the shell 1 is as shown in FIG. Figure 1 As shown, it can be arranged at the front end outlet of the kiln body 2 for firing refractory bricks, so as to facilitate the transportation of the refractory bricks to the inside of the shell 1 for cooling after the firing is completed; cooling air ducts 3 are arranged on the symmetrical inner walls of the shell 1, and the two cooling air ducts 3 are connected, one of the cooling air ducts 3 is connected to the cooling fan 4 arranged on the shell 1, and the cooling fan 4 is used to introduce the cooling gas into the cooling air duct 3 for circulation, so as to realize the cooling of the inside of the shell 1; air holes are arranged on the opposite sides of the two cooling air ducts 3, and the air holes on the two cooling air ducts 3 are inclined in opposite directions. The inclined opening of the air holes can avoid the cooling gas from blowing directly to the surface of the refractory bricks and causing cracks on the surface, so as to realize the flow of cooling gas on both sides of the refractory bricks; the opposite inclination of the air holes on both sides is helpful for the cooling gas convection to form a vortex airflow, which drives the heat released by the middle refractory bricks to rise, and the heat dissipation is realized quickly through the heat sink 5 arranged on the top of the shell 1. Preferably, in this embodiment, a guide pipe 6 communicating with the air holes is obliquely provided on the outside of the cooling air duct 3. The guide pipe 6 serves to guide and drain the cooling gas, thereby reducing interference between the cooling gases blown out of different air holes.

[0021] Further, a circulating cooling pipe 7 is arranged on the top of each cooling air duct 3, wherein two circulating cooling pipes 7 are connected, and the two cooling air ducts 3 are connected through the circulating cooling pipe 7; the setting of the circulating cooling pipe 7 can further extend the path of the cooling gas flowing inside the shell 1, realize its full exchange with heat, and reduce the energy waste caused by the rapid entry and exit of the cooling gas; wherein the two circulating cooling pipes 7 are connected through a shunt pipe 8, the shunt pipe 8 is arranged at one end of the two circulating cooling pipes 7, and the cooling fan 4 is connected with the shunt pipe 8; using the cooling fan 4 to introduce the cooling gas into the two circulating cooling pipes 7 through the shunt pipe 8 can realize the cooling gas to move evenly to the circulating cooling pipes 7 and the cooling air duct 3 on both sides, reduce the temperature difference on both sides of the shell 1, and ensure the uniformity of cooling and cooling. In addition, the circulating cooling pipe 7 and the cooling air duct 3 are connected through the drainage channel 9, and the outlet end of the drainage channel 9 is connected and arranged in the middle of the cooling air duct 3, so as to reduce the problem that the difference in the air volume in the air holes at different positions is large due to the introduction of cooling gas from one end of the cooling air duct 3. Preferably, the size of the air holes increases gradually from the position close to the drainage channel 9 to the position far away from the drainage channel 9, so as to improve the uniformity of the air output between different air holes and ensure the uniformity of the temperature reduction and cooling.

[0022] Furthermore, a heat spreader 10 is provided at the top of the housing 1, and the heat sink 5 is provided on the heat spreader 10. The heat spreader 10 can absorb and transfer the rising heat inside the housing 1 by the process of heat conduction, evaporation and condensation, thereby improving the heat dissipation efficiency and enhancing the heat dissipation effect. Preferably, a filter 11 is provided under the heat spreader 10 to filter the external dust. The rising hot air flow carries the dust, causing scouring and wear on the heat spreader 10, thus affecting its service life.

[0023] Furthermore, in this embodiment, door panels 12 are provided on both sides of the shell 1, which can be raised and lowered. The door panels 12 can be raised and lowered by a threaded screw or a cylinder to seal the inside of the shell 1 and reduce the loss of cold. In addition, the side walls and the bottom of the shell 1 are hollow structures, and the inside is filled with heat-insulating materials, which further reduces the escape and diffusion of cold inside the shell 1 to the outside and reduces energy loss.

[0024] When the utility model is used, after the refractory bricks are fired, the pallet cart carrying the bricks can be directly moved into the shell 1, and the cooling fan 4 can be started. The cooling air flow will first enter the circulating cooling pipe 7 to indirectly cool the inside of the shell 1, and then the cooling gas will enter the cooling air duct 3 and be discharged from the air holes on the cooling air duct 3 into the shell 1 to achieve direct cooling. Since the cooling gas has been drained through the circulating cooling pipe 7 at this time, the temperature of the cooling gas is higher than when it first enters, so the cooling gas discharged through the air holes will not produce a large temperature impact on the refractory bricks. In addition, the inclined opening of the air holes cooperates with each other to greatly reduce the occurrence of cracks in the refractory bricks during the cooling process, reduce the scrap rate, and save production costs.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
