Description

Technical Field

[0001] The utility model relates to an improvement of industrial drying equipment, in particular to a heat insulation and sealing device for a Teflon wire baking equipment. Background Art

[0002] Teflon is a common non-stick material, usually used for attaching to the surface of wires or cookware to prevent adhesion. Taking wires as an example, generally, Teflon paint is sprayed on the surface of the wires and then baked at a high temperature of about 260 °C, so that the Teflon material can be attached to the surface of the wires. This process usually involves workers. When baked at a high temperature, the Teflon material will evaporate slightly, and when inhaled by workers, it usually causes damage to the body. Moreover, workers working in a high-temperature environment for a long time are also at great risk. When the conventional Teflon baking equipment is used, it is usually baked at normal temperature and pressure. At this time, there will still be a small amount of steam leakage, which will eventually be mixed in the air and inhaled into the human body, thus affecting health. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a heat insulation and sealing device for a Teflon wire baking equipment.

[0004] The utility model is realized by adopting the following technical scheme: a heat insulation and sealing device for a Teflon wire baking equipment, including a sealing cover and a negative pressure component. The sealing cover covers the baking equipment, and the negative pressure component is communicated with the sealing cover to extract the air in the sealing cover. A heat dissipation channel is arranged on the periphery of the sealing cover, and when the negative pressure component extracts air, external air enters the sealing cover through the heat dissipation channel.

[0005] A bearing platform is arranged around the baking equipment to support the sealing cover. When the sealing cover covers the baking equipment, the opening of the sealing cover abuts against the bearing platform.

[0006] The heat dissipation channel is a first heat dissipation hole, and the first heat dissipation hole is arranged on the sealing cover and is evenly arranged along the circumferential direction of the sealing cover. The first heat dissipation hole communicates with the internal space of the sealing cover.

[0007] The heat dissipation channel is arranged on the bearing platform, and the heat dissipation channel is evenly arranged along the circumferential direction of the sealing cover. The heat dissipation channel communicates with the internal space of the sealing cover.

[0008] The heat dissipation channel is a second heat dissipation hole, and the second heat dissipation hole is arranged on the bearing platform and is arranged along the circumferential direction of the sealing cover. The second heat dissipation hole communicates with the internal space of the sealing cover.

[0009] The heat dissipation channel is a heat dissipation groove, and the heat dissipation groove extends radially outward with the baking equipment as the center. When the sealing cover abuts against the bearing platform, there is a gap between the sealing cover and the bottom of the heat dissipation groove.

[0010] A sealing gasket is provided at the edge of the sealing cover, and the sealing gasket is arranged along the periphery of the sealing cover.

[0011] The negative pressure assembly is communicated with the sealing cover through a pipeline, and a one-way valve is arranged in the pipeline.

[0012] The negative pressure assembly includes a negative pressure fan. The air extraction port of the negative pressure fan is communicated with the pipeline. When the negative pressure fan works, the one-way valve opens the pipeline, and when the negative pressure fan stops, the one-way valve closes the pipeline.

[0013] Compared with the prior art, when in use, the present utility model is covered with a sealing cover outside the baking equipment, and when the baking equipment bakes the Teflon coating, the negative pressure fan is used to always extract air from the sealing cover, and the external air flow enters the sealing cover through the heat dissipation channel. That is, when the baking equipment is working, the air around the baking equipment is always in a flowing state and always flows towards the negative pressure fan, so that a small amount of flue gas containing Teflon components generated by baking is sucked by the negative pressure fan and will not be scattered in the surrounding air, thereby reducing the impact on the operator.

[0020] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0021] Referring to Figure 1, a heat insulation and sealing device for a Teflon wire baking equipment, includes a sealing cover 1 and a negative pressure component. The sealing cover 1 covers the baking equipment, and the negative pressure component is connected to the sealing cover 1 to extract the air inside the sealing cover 1. A heat dissipation channel is provided at the periphery of the sealing cover 1. When the negative pressure component extracts air, external air enters the sealing cover 1 through the heat dissipation channel. To clearly show the structure of the sealing device, the baking equipment is not shown in the drawings of this application. In this embodiment, after the sealing cover 1 covers the baking equipment, the baking equipment can be fixed with bolts, that is, the sealing cover 1 is fixed to the outer shell of the baking equipment to maintain the sealing effect of the sealing cover 1.

[0022] Refer to Figures 2 - 4 , of course, the sealing cover 1 can also be used in cooperation with the bearing platform 2. When the bearing platform 2 is not in use, it can be placed around the baking equipment. That is, the bearing platform 2 can be annular and surround the baking equipment. When the sealing cover 1 covers the baking equipment, the opening of the sealing cover 1 abuts against the bearing platform 2 to form a relatively airtight environment. At this time, the negative pressure component is activated, so that the air flow in the sealing cover 1 flows towards the negative pressure component, and a small amount of flue gas containing Teflon components generated by baking is sucked by the negative pressure fan and will not be scattered in the surrounding air, thus reducing the impact on the operator.

[0023] One solution for the heat dissipation channel is the first heat dissipation holes 3. The first heat dissipation holes 3 are provided on the sealing cover 1 and are evenly arranged along the circumferential direction of the sealing cover 1. The first heat dissipation holes 3 communicate with the internal space of the sealing cover 1. At this time, whether it is used in cooperation with the bearing platform 2 or not, an air flow can be formed in the sealing cover 1, so that a small amount of flue gas containing Teflon components generated by baking is sucked by the negative pressure fan and will not be scattered in the surrounding air, thus reducing the impact on the operator.

[0024] Of course, the heat dissipation channel is provided on the bearing platform 2 and is evenly arranged along the circumferential direction of the sealing cover 1. The heat dissipation channel communicates with the internal space of the sealing cover 1. In this solution, the heat dissipation channel can be the second heat dissipation holes 4. The second heat dissipation holes 4 are provided on the bearing platform 2 and are arranged along the circumferential direction of the sealing cover 1. The second heat dissipation holes 4 communicate with the internal space of the sealing cover 1. The heat dissipation channel can also be a heat dissipation groove 5. The heat dissipation groove 5 extends radially outward with the baking equipment as the center. There is a gap between the sealing cover 1 and the bottom of the heat dissipation groove 5 when the sealing cover 1 abuts against the bearing platform 2. When the negative pressure component works, an air flow can be formed in the sealing cover 1, so that a small amount of flue gas containing Teflon components generated by baking is sucked by the negative pressure fan and will not be scattered in the surrounding air, thus reducing the impact on the operator.

[0025] A sealing gasket 6 is provided at the edge of the sealing cover 1, and the sealing gasket 6 is arranged along the periphery of the sealing cover 1. The use of the sealing gasket 6 improves the sealing performance of the sealing cover 1. The negative pressure assembly is connected to the sealing cover 1 through a pipeline 7, and a check valve is provided in the pipeline 7. The negative pressure assembly includes a negative pressure fan. The air extraction port of the negative pressure fan is connected to the pipeline 7. When the negative pressure fan operates, the check valve opens the pipeline 7, and when the negative pressure fan stops, the check valve closes the pipeline 7.

[0026] Compared with the prior art, when in use, the present utility model is covered with a sealing cover 1 outside the baking equipment, and a negative pressure fan is used to always extract air from the inside of the sealing cover 1 when the baking equipment bakes the Teflon coating, while the external air flow enters the inside of the sealing cover 1 through the heat dissipation channel. That is, when the baking equipment is working, the air around the baking equipment is always in a flowing state and always flows towards the negative pressure fan, so that a small amount of flue gas containing Teflon components generated by baking is sucked by the negative pressure fan and will not be scattered in the surrounding air, thereby reducing the impact on the operators.

[0027] The above-mentioned embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope of protection required by the present utility model.
