Description

Technical Field

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

[0002] Refractory materials are materials whose physical and chemical properties allow them to be used in high-temperature environments. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, electric power and other industrial fields. They are generally a type of inorganic non-metallic materials with a fire resistance of not less than 1580°C. Existing air cooling exchanges heat with the surface of hot objects through gas medium, and then uses the fluidity of the air flow to take away the heat to achieve rapid cooling of the material. The air flow power of existing air cooling equipment is mostly provided by pumps. The gas medium stays in the box for a short time, and the gas medium is discharged from the equipment without sufficient heat exchange with the refractory material. Not only does it waste energy, but also for some production processes that need to use inert gas medium for heat dissipation, its gaseous raw materials are not fully utilized. This gas supply feature is also prone to uneven surface temperature of heat exchange refractory materials, which in turn leads to slow material cooling speed and poor heat exchange effect, affecting the cooling efficiency of the material.

The gas after the heat exchange flows out of the box through the air outlet from the space between the guide plate and the top wall of the box with the heat. The interior of the box is divided into multiple spaces by the setting of the horizontal plate and the guide plate, which lengthens the flow path of the gas and increases the residence time of the gas inside the box, so that sufficient heat exchange can be carried out between the gas and the refractory material.

Example

[0026] like Figure 1-9 As shown, this embodiment discloses an air cooling device for refractory material processing, which includes a box body 1, a blowing device 2 for blowing air toward the inside of the box body 1 is connected on the side wall of the box body 1, a horizontal plate 3 is fixedly provided inside the box body 1, and the blowing device 2 is connected and arranged below the horizontal plate 3, and a through hole is provided on the plate surface of the end of the horizontal plate 3 away from the blowing device 2. A guide plate 4 is fixedly provided inside the box body 1 and above the horizontal plate 3, and a laterally extending supporting cross bar 5 is fixedly provided inside the box body 1 between the guide plate 4 and the horizontal plate 3, and a first placement plate 6 for placing refractory materials is slidably connected above the supporting cross bar 5. A side door 7 is provided on the right side wall of the box body 1, and the right end of the first placement plate 6 extends to the outside of the side door 7, and the first placement plate 6 is slidably connected to the side door 7. An air outlet 8 is provided on the upper surface of the box body 1.

[0027] In this embodiment, a transverse plate 3 and a guide plate 4 are arranged inside the box 1, so that the gas blown out of the blowing device 2 flows from the inner bottom space of the box 1 through the through hole into the space between the transverse plate 3 and the guide plate 4. The transverse plate 3 and the guide plate 4 play a role in guiding the flow of gas, prolonging the residence time of the gas inside the box 1, and accelerating the air cooling speed of the material. By arranging a supporting crossbar 5 and a first placement plate 6 between the transverse plate 3 and the guide plate 4, the material can be easily placed in the cooling space between the transverse plate 3 and the guide plate 4, which is convenient for placing and removing the material and improving work efficiency. Through the setting of the side door 7, it is convenient to pull the first placement plate 6 out of the box 1 to place the material to be cooled, and speed up the placement or removal of the material. When in use, the first placement plate 6 is pulled out to the outside of the box 1 to place the material, and after the material is placed above the first placement plate 6, the first placement plate 6 is pushed back into the box 1. The blowing device 2 is started to work, and the blowing device 2 blows toward the space inside the bottom of the box body 1. The gas flows from the bottom of the box body 1 through the through hole into the cooling space between the horizontal plate 3 and the guide plate 4 of the box body 1. Since the material is located inside the cooling space, the gas exchanges heat with the material when flowing through the cooling space. The gas after the heat exchange flows out of the space between the guide plate 4 and the top wall of the box body 1 through the air outlet 8 to the outside of the box body 1 with the heat. The setting of the horizontal plate 3 and the guide plate 4 divides the inside of the box body 1 into multiple spaces, lengthens the flow path of the gas, increases the residence time of the gas inside the box body 1, and makes sufficient heat exchange between the gas and the refractory material. Example

[0028] like Figure 1-9 As shown, this embodiment discloses an air cooling device for refractory material processing, which includes a box body 1, a blowing device 2 for blowing air toward the inside of the box body 1 is connected on the side wall of the box body 1, a horizontal plate 3 is fixedly provided inside the box body 1, and the blowing device 2 is connected and arranged below the horizontal plate 3, and a through hole is provided on the plate surface of the end of the horizontal plate 3 away from the blowing device 2. A guide plate 4 is fixedly provided inside the box body 1 and above the horizontal plate 3, and a laterally extending supporting cross bar 5 is fixedly provided inside the box body 1 between the guide plate 4 and the horizontal plate 3, and a first placement plate 6 for placing refractory materials is slidably connected above the supporting cross bar 5. A side door 7 is provided on the right side wall of the box body 1, and the right end of the first placement plate 6 extends to the outside of the side door 7, and the first placement plate 6 is slidably connected to the side door 7. An air outlet 8 is provided on the upper surface of the box body 1.

[0029] For better effect, a support plate 9 extending vertically upward is fixedly provided on the upper surface of the box body 1 and located at the side of the air outlet 8, and a second placement plate 10 for placing refractory materials is fixedly provided on the support plate 9, and the second placement plate 10 is located above the air outlet 8. Through the setting of the second placement plate 10, when in use, after the gas comes out of the air outlet 8, the gas impacts the second placement plate 10. If materials are placed on the second placement plate 10, the exhaust gas impacts the materials on the second placement plate 10 to cool them down, thereby realizing the secondary utilization of the exhaust gas.

[0030] For better effect, the second placement plate 10 includes a first support rod and a second support rod fixedly connected to the side wall of the support plate 9, and a plurality of longitudinal rods are fixedly arranged between the first support rod and the second support rod. An inclined plate 11 is fixedly connected to the upper surface of the box body 1 and located at the side of the air outlet 8. The arrangement of the inclined plate 11 can guide the gas blown out from the air outlet 8 to impact the second placement plate 10.

[0031] For better effect, the guide plate 4 includes an inclined portion 15 and a straight section fixedly connected to the inclined portion 15. The upper end of the inclined portion 15 is fixedly connected to the left side of the lower opening of the air outlet 8, the lower end of the inclined portion 15 is inclined to the right below the air outlet 8, and the left end of the straight section is fixedly connected to the lower end of the inclined portion 15.

[0032] For better effect, a plurality of inclined guide support plates 12 are fixedly provided on the lower surface of the guide plate 4, and a plurality of inclined transverse support plates 13 are fixedly provided on the upper surface of the transverse plate 3, and the guide support plates 12 are arranged corresponding to the transverse support plates 13. Through the arrangement of the plurality of guide support plates 12 and the plurality of transverse support plates 13, when the gas enters and reaches the cooling space, the gas first hits the inclined portion 15 from the through hole, and after the gas is countered by the inclined portion 15, the gas passes through the first placement plate 6, performs heat exchange with the refractory material on the first placement plate 6, and then hits the first transverse support plate 13. After the gas hits the first transverse support plate 13, it hits the first guide support plate 12 again after counterattack, so that the gas finally flows out from the space between the guide plate 4 and the top wall of the box body 1 to the outside of the box body 1. While the transverse support plates 13 and the guide support plates 12 block the flow of gas, they also act on the refractory material from the upper and lower directions for heat exchange, and the heat exchange of the refractory material is more uniform.

[0033] For better effect, a plurality of ventilation holes 22 are provided on the upper surface of the horizontal plate 3, and the inner diameter of the ventilation holes 22 gradually decreases from one end of the through hole of the horizontal plate 3 to the other end of the horizontal plate 3. The ventilation holes 22 are circular. With the setting of the ventilation holes 22, when the blowing device 2 transports gas to the inside of the box body 1, part of the gas below the horizontal plate 3 will flow into the top of the horizontal plate 3 through the ventilation holes 22, and the porous gas flowing out of the ventilation holes 22 will flow vertically downward. Due to the presence of the porous gas, a lateral force will be applied to the main gas flow above the horizontal plate 3 to slow down the flow rate of the main gas flow, so that the main gas flow can stay in the cooling space for a longer time, and further perform sufficient heat exchange.

[0034] For better effect, the blowing device 2 includes a first blower and a second blower. Support feet 14 are fixedly provided at the four corners of the lower end of the box body 1. The supporting cross bar 5 includes a first rod 16 and a second rod, and the vertical sections of the first rod 16 and the second rod are both rectangular, and the upper surfaces of the first rod 16 and the second rod are provided with a slide groove 17. The lower surface of the first placement plate 6 is fixedly provided with a first sliding protrusion 18 and a second sliding protrusion, and the first sliding protrusion 18 is slidably connected in the slide groove 17 of the first rod 16, and the second sliding protrusion is slidably connected in the slide groove 17 of the second rod. Through the cooperation of the two slide grooves 17 with the first sliding protrusion 18 and the second sliding protrusion respectively, the first placement plate 6 is smoother and more stable when being pulled out or pushed into the box body 1.

[0035] For better effect, a plastic handle is fixedly provided at one end of the first placement plate 6 located outside the box body 1. A plurality of strip holes 19 are provided on the plate surface of the first placement plate 6. A baffle plate 20 is provided on the side door 7, and the upper end of the baffle plate 20 is rotatably connected to the upper end of the side door 7 through a horizontal axis 21. The strip holes 19 are provided to increase the contact area between the refractory material and the gas flow, so as to make the heat exchange faster. The baffle plate 20 is provided to prevent the gas flow inside the box body 1 from leaking from the side door 7.

[0036] In this embodiment, a transverse plate 3 and a guide plate 4 are arranged inside the box 1, so that the gas blown out of the blowing device 2 flows from the inner bottom space of the box 1 through the through hole into the space between the transverse plate 3 and the guide plate 4. The transverse plate 3 and the guide plate 4 play a role in guiding the flow of gas, prolonging the residence time of the gas inside the box 1, and accelerating the air cooling speed of the material. By arranging a supporting crossbar 5 and a first placement plate 6 between the transverse plate 3 and the guide plate 4, the material can be easily placed in the cooling space between the transverse plate 3 and the guide plate 4, which is convenient for placing and removing the material and improving work efficiency. Through the setting of the side door 7, it is convenient to pull the first placement plate 6 out of the box 1 to place the material to be cooled, and speed up the placement or removal of the material. When in use, the first placement plate 6 is pulled out to the outside of the box 1 to place the material, and after the material is placed above the first placement plate 6, the first placement plate 6 is pushed back into the box 1. The blowing device 2 is started to work, and the blowing device 2 blows toward the space inside the bottom of the box body 1. The gas flows from the bottom of the box body 1 through the through hole into the cooling space between the horizontal plate 3 and the guide plate 4 of the box body 1. Since the material is located inside the cooling space, the gas exchanges heat with the material when flowing through the cooling space. The gas after the heat exchange flows out of the space between the guide plate 4 and the top wall of the box body 1 through the air outlet 8 to the outside of the box body 1 with the heat. The setting of the horizontal plate 3 and the guide plate 4 divides the inside of the box body 1 into multiple spaces, lengthens the flow path of the gas, increases the residence time of the gas inside the box body 1, and makes sufficient heat exchange between the gas and the refractory material.

[0037] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
