Description

Technical Field

[0001] This utility model relates to a portable cooling structure, and more particularly to a portable cooling device for hot repair of high-temperature kilns. Background Technology

[0002] During the production process of fiberglass kilns, the temperature of the kiln walls and surrounding space is very high (the temperature of the kiln walls can reach over 1000℃). In the later stages of use, the kiln walls and passageways require frequent hot repairs or brick reinforcement due to severe erosion. During operation, due to the extremely high temperature of the working surface and area, the complex working environment, and the small working space, it is necessary to remove the heat from the working area and cool it down quickly to facilitate operation. However, currently available commercial cooling fans or blowers have low air speed, slow cooling speed, poor high temperature resistance and explosion-proof performance, and cannot be used in confined spaces. Therefore, there is an urgent need for a portable cooling device that is highly portable, can cool down quickly, and is explosion-proof and high temperature resistant. Utility Model Content

[0003] The purpose of this utility model is to provide a portable cooling device for hot repair of high-temperature kilns. It has a simple structure, is easy to manufacture, has a low cost, and is more portable. It is easy to install or carry by hand and is suitable for use in the entire kiln and passageway area. It also has good explosion-proof and high-temperature resistance performance, and at the same time, it has a strong cooling effect. It can achieve a directional cooling rate of 1000℃→300℃ / minute for local kiln pool wall temperature and rapid cooling of local space.

[0004] This utility model provides the following technical solution: A portable cooling device for hot repair of high-temperature kilns includes a main body, a mixing air duct, a regulating valve, and a support. The main body is a ring-shaped injector, designed to utilize the Kernida effect to propel compressed air at high speed through the ring injector. Guided by the curvature of the wall, the injector adsorbs surrounding air, amplifying the gas flow (by 20-25 times) and increasing the air volume at the outlet. Figure 2 As shown, this design greatly enhances the cooling effect. The mixing duct is connected to the outlet of the annular injector and is flared outwards in a funnel shape, which can gather the mixture of compressed air and air and control the airflow direction and cooling area, further improving the cooling effect. The mixing duct is equipped with a handle for easy hand-carrying in complex environments. The regulating valve is connected to the inlet of the cooling device body and is equipped with a pressure gauge for adjusting and controlling the cooling airflow and cooling effect. The bracket is a tripod that can be detachably installed on the cooling device body for fixing the cooling device body.

[0005] Preferably, the mixing duct uses bolts to fix the duct inlet to the annular injector outlet, which has a relatively simple structure and is easy to install.

[0006] Preferably, the axial length of the mixing duct is 600-700mm, the inlet inner diameter of the mixing duct is 150-160mm, and the outlet inner diameter of the mixing duct is 280-300mm.

[0007] Preferably, the mixing duct is made of galvanized iron sheet with a thickness of 1 mm.

[0008] Preferably, the top of the tripod is provided with an adapter pipe, and the cylindrical tube is detachably connected to the main body of the cooling device by screws. The adapter pipe is installed inside the cylindrical tube, so that the opening orientation of the mixing air duct can be adjusted more flexibly.

[0009] Preferably, the tripod includes a set of horizontal connecting columns and two sets of support legs mounted on the circumference of the connecting columns via sliders. The surface of the connecting columns has two sets of arc-shaped grooves that cooperate with the two sets of sliders. Thus, the two sets of support legs can be independently adjusted in the positioning angle along the grooves, and after positioning, they are locked in the arc-shaped grooves with screws to restrict the sliders from moving further, thus improving flexibility.

[0010] The beneficial effects of this utility model are as follows: The portable cooling device for hot repair of high-temperature kilns provided by this utility model has a simple structure, is easy to manufacture, has a low cost, and is more portable. It is easy to install or carry by hand and is suitable for use in the entire kiln and passageway area. It also has good explosion-proof and high-temperature resistance performance, and at the same time, it has a very strong cooling effect. It can achieve a directional cooling rate of 1000℃→300℃ / minute for local kiln pool wall temperature and rapid cooling of local space. Attached Figure Description

Detailed Implementation

[0012] like Figure 1-3As shown, a portable cooling device for hot repair of a high-temperature kiln, in this embodiment, includes a cooling device body, a mixing air duct, a regulating valve, and a support. The cooling device body is a ring-shaped injector, designed to utilize the Kernida effect to propel compressed air at high speed through the ring-shaped injector. Guided by the curvature of the wall, it adsorbs surrounding air, thereby amplifying the gas flow rate (by 20-25 times) and increasing the air volume at the outlet. Figure 2 As shown, this design greatly enhances the cooling effect. The mixing duct is connected to the outlet of the annular injector and is flared outwards in a funnel shape, which can gather the mixture of compressed air and air and control the airflow direction and cooling area, further improving the cooling effect. The mixing duct is equipped with a handle for easy hand-carrying in complex environments. The regulating valve is connected to the inlet of the cooling device body and is equipped with a pressure gauge for adjusting and controlling the cooling airflow and cooling effect. The bracket is a tripod that can be detachably installed on the cooling device body for fixing the cooling device body.

[0013] The mixing duct uses bolts to fix the duct inlet to the annular ejector outlet, which has a relatively simple structure and is easy to install.

[0014] The axial length of the mixing duct is 600-700mm, the inlet inner diameter of the mixing duct is 150-160mm, and the outlet inner diameter of the mixing duct is 280-300mm.

[0015] The mixing duct is made of galvanized iron sheet with a thickness of 1mm.

[0016] The top of the tripod is equipped with an adapter pipe, and the cylindrical tube is detachably connected to the main body of the cooling device by screws. The adapter pipe is installed inside the cylindrical tube, which allows for more flexible adjustment of the opening orientation of the mixing air duct.

[0017] The tripod includes a set of horizontal connecting columns and two sets of support legs mounted on the circumference of the connecting columns via sliders. The surface of the connecting columns has two sets of arc-shaped grooves that cooperate with the two sets of sliders. Thus, the two sets of support legs can be independently adjusted along the grooves to adjust their positioning angle. After positioning, they are locked in the arc-shaped grooves with screws to restrict the sliders from moving further, thus improving flexibility.

[0018] The working principle of this utility model is as follows: This utility model provides a portable cooling device for hot repair of high-temperature kilns. In use, compressed air enters the annular injector of the cooling device through a regulating valve. The compressed air is used to provide high-pressure airflow for the air-cooling system. It is directly sprayed onto the high-temperature area of ​​the kiln through the annular injector. The airflow accelerates heat dissipation and forms forced convection cooling. The mixing air duct is funnel-shaped, which can gather the mixture of compressed air and air and control the airflow direction and cooling area, further improving the cooling effect. The mixing air duct is equipped with a handle, which can facilitate manual operation in complex environments. The overall structure is relatively simple, easy to manufacture, low in cost, and more portable. It is easy to install or carry, suitable for use in the entire kiln and passageway area. It also has good explosion-proof and high-temperature resistance performance. At the same time, the cooling effect is extremely strong, which can achieve a directional cooling rate of 1000℃→300℃ / minute for local kiln pool wall temperature and rapid cooling of local space.
