Silicone rubber energy-saving and environmentally friendly oven

Abstract

This utility model discloses an energy-saving and environmentally friendly silicone rubber oven, which includes a cabinet, an inner liner, and an electromagnetic heating wire. The inner liner is disposed within the cabinet, with its lower ends extending along its length to form a baking channel that runs through the entire cabinet. The upper part of the inner liner is shortened to form a stepped protrusion, and the electromagnetic heating wire is wound around the outer wall of the stepped protrusion. During operation, heat is generated using the principle of electromagnetic induction, raising the temperature throughout the inner liner and thus heating and vulcanizing the silicone rubber wire passing through the baking channel. Compared with traditional electric heating tubes, the electromagnetic heating wire has higher heating efficiency, can raise the temperature more quickly, reduce heat loss, and lower energy consumption. Moreover, since the electromagnetic heating wire is wound around the inner liner, the heating is uniform, allowing heat to be more evenly distributed within the baking channel, effectively solving the problem of uneven temperature caused by the positional spacing of traditional electric heating tubes, thus improving the heating effect and the vulcanization quality of the silicone rubber wire.

Description

Technical Field

[0001] This utility model belongs to the field of silicone rubber wire and cable manufacturing technology, specifically relating to an energy-saving and environmentally friendly silicone rubber oven used for the vulcanization of silicone rubber wires and cables. Background Technology

[0002] Silicone rubber insulated wires and cables, due to their insulator being silicone rubber, have stable chemical properties and excellent heat resistance, cold resistance, environmental resistance, electrical insulation, and fatigue resistance. They are currently widely used in lighting fixtures, household appliances, electric heating appliances, instruments, motor lead wires, and high-temperature environments such as electronics, lighting fixtures, and gas appliances.

[0003] In the production of silicone rubber insulated wires and cables, heating and vulcanization are required to achieve stable physical and chemical properties for the silicone rubber material. This involves passing the silicone rubber wire through an oven and subjecting it to vulcanization under specific temperature and time conditions. Most existing ovens use electric heating elements, with multiple heating elements spaced apart along the conveying direction. While this achieves heating, the gaps between adjacent heating elements result in uneven heating; the temperature is lower in the middle of the gap and higher closer to the heating element, leading to low heating efficiency and high energy consumption. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a silicone rubber energy-saving and environmentally friendly oven with a reasonable structural design, uniform heating, and good vulcanization effect.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A silicone rubber energy-saving and environmentally friendly oven includes a cabinet, an inner liner, and an electromagnetic heating wire. The inner liner is disposed in the cabinet, and its lower two ends extend along its length to form a baking channel that runs through the entire cabinet. The upper part of the inner liner is shortened to form a stepped protrusion, and the electromagnetic heating wire is wound around the outer wall of the stepped protrusion.

[0007] In a preferred embodiment of this invention, the inner liner is formed by stamping and bending a stainless steel plate, and several reinforcing arches extending along the long side are distributed on the lower side wall of the inner liner. These reinforcing arches increase the structural stability of the side wall, preventing deformation due to temperature changes and pressure during heating, thus extending the service life of the inner liner and ensuring the reliability of the oven during long-term use.

[0008] In a preferred embodiment of this invention, a plurality of reinforcing plates perpendicular to the long side direction are spaced apart on the outer surface of the lower side wall of the inner liner. The reinforcing plates have clearances adapted to the reinforcing arches. This ensures a tight fit between the reinforcing plates and the inner liner side wall, while avoiding interference with the reinforcing arches, further improving the overall structural strength and stability of the inner liner and enhancing its resistance to deformation.

[0009] As a preferred embodiment of this utility model, a plurality of support frames are provided at intervals corresponding to the stepped protrusions inside the inner liner. The middle part of the support frame extends horizontally to form a horizontal part, and the two ends of the support frame are symmetrically bent upward to form a vertical part. The vertical part is tightly fixed to the two opposite inner side walls of the inner liner, so that the support frame can firmly support the internal structure of the inner liner, while providing a stable installation base for components such as electromagnetic heating wires, and improving the deformation resistance of the inner liner during the heating process, ensuring the shape and dimensional stability of the inner liner, thereby ensuring the smooth flow of the baking channel and the uniformity of the heating effect, which is beneficial to improving the vulcanization quality of the silicone rubber wire.

[0010] As a preferred embodiment of this utility model, the lower edge of the inner liner is turned outward to form a support surface, the support surface is disposed on a channel steel, and the channel steel is disposed on a base, which effectively improves the stability of the inner liner installation.

[0011] In a preferred embodiment of this invention, aluminum silicate insulation cotton is provided between the support surface and the channel steel, and aluminum silicate insulation cotton is provided between the channel steel and the base. Utilizing the excellent thermal insulation properties of the aluminum silicate insulation cotton, heat conduction and loss from the bottom of the inner liner to the outside is effectively reduced, energy consumption is lowered, energy utilization efficiency is improved, and the external environment is protected from high temperatures.

[0012] As a preferred embodiment of this utility model, the inner liner is provided with heat insulation plates at the edges of the openings at both ends of the baking channel. The heat insulation plates are made of aluminum silicate, which has good heat insulation performance and can effectively prevent heat loss from the openings at both ends of the baking channel, thereby reducing heat loss, improving heating efficiency and energy utilization, and ensuring that the silicone rubber line can be in a stable high-temperature environment in the baking channel, which is beneficial to improving the vulcanization effect and product quality.

[0013] In a preferred embodiment of this invention, the box body is provided with high-temperature resistant fireproof plates at the edges of the openings at both ends corresponding to the baking channel. The high-temperature resistant fireproof plates are mica sheets. Mica sheets have excellent high-temperature resistance and fireproof properties, effectively preventing the silicone rubber wire from igniting due to excessive temperature when entering or exiting, thus improving safety.

[0014] In a preferred embodiment of this invention, the top surface of the oven body is provided with a heat dissipation vent, and a cooling fan is installed on the vent. When the internal temperature of the oven is too high, the cooling fan exhausts the hot air through the vent, effectively controlling the internal temperature of the oven and preventing problems such as equipment damage or excessive vulcanization of the silicone rubber line caused by excessive temperature. This ensures the stable operation of the oven and the stability of product quality.

[0015] As a preferred embodiment of this utility model, a side mounting rack is provided on the outer wall of the oven, which increases the functional expandability and operational convenience of the oven, making it easier for users to install and configure related equipment according to actual needs, and improving the practicality and ease of use of the equipment.

[0016] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design, constructing the oven's heating structure through an inner liner and electromagnetic heating wires. The lower part of the inner liner forms a baking channel that runs through the entire oven body, facilitating the passage of the silicone rubber wire for heating and vulcanization. The upper part of the inner liner forms a stepped protrusion, facilitating the winding of the electromagnetic heating wire. During operation, heat is generated using the principle of electromagnetic induction, raising the temperature throughout the inner liner and thus heating and vulcanizing the silicone rubber wire passing through the baking channel. Compared to traditional electric heating tubes, electromagnetic heating wires have higher heating efficiency, can raise the temperature more quickly, reduce heat loss, and lower energy consumption. Furthermore, since the electromagnetic heating wire is wound around the inner liner, heating is uniform, allowing heat to be more evenly distributed within the baking channel. This effectively solves the problem of uneven temperature caused by the spacing of traditional electric heating tubes, improving heating efficiency and the vulcanization quality of the silicone rubber wire.

[0022] Example: See Figures 1 to 4 This embodiment provides a silicone rubber energy-saving and environmentally friendly oven, which includes a cabinet 1, an inner liner 2, an electromagnetic heating wire 3, and a cooling fan 4.

[0023] The inner liner 2 is disposed inside the oven body 1, and its lower ends extend along its length to form a baking channel 21 that runs through the entire oven body 1. Specifically, the inner liner 2 is made of stainless steel sheet by stamping and bending. The stainless steel sheet material can be SUS304 or SUS310 stainless steel sheet, and the overall transverse cross-section after stamping and bending is "n" shaped. Preferably, a number of reinforcing arches 22 extending along their long sides are distributed on the lower sidewall of the inner liner 2. The reinforcing arches 22 can increase the structural stability of the sidewall, prevent the sidewall from deforming due to temperature changes and pressure during heating, extend the service life of the inner liner 2, and ensure the reliability of the oven during long-term use. A number of reinforcing plates 23 perpendicular to their long sides are provided at intervals on the outer surface of the lower sidewall of the inner liner 2. The reinforcing plates 23 are provided with clearance positions adapted to the reinforcing arches 22. This ensures that the reinforcing plate 23 fits tightly against the side wall of the inner liner 2, while avoiding interference with the reinforcing arch 22, further improving the overall structural strength and stability of the inner liner 2 and enhancing its resistance to deformation.

[0024] Preferably, heat insulation plates 24 are provided at the edges of the openings at both ends of the inner liner 2 corresponding to the baking channel 21. The heat insulation plates 24 are made of aluminum silicate and have good heat insulation performance. They can effectively prevent heat loss from the openings at both ends of the baking channel 21, reduce heat loss, improve heating efficiency and energy utilization, and ensure that the silicone rubber line can be in a stable high-temperature environment in the baking channel 21, which is conducive to improving the vulcanization effect and product quality.

[0025] High-temperature resistant fireproof plates 25 are provided at the edges of the openings at both ends of the housing 1 corresponding to the baking channel 21. The high-temperature resistant fireproof plates 25 are mica plates. Mica plates have excellent high-temperature resistance and fireproof properties, which can effectively prevent the silicone rubber wire from catching fire due to excessive temperature when it enters and exits, thus improving safety.

[0026] The length of the upper part of the inner container 2 is shortened by a certain distance to form a stepped convex part 26, and the inner container 2 as a whole is "convex" in shape when viewed from the side. The distance by which the length of the upper part of the inner container 2 is shortened is slightly greater than the winding thickness of the electromagnetic heating wire 3. The electromagnetic heating wire 3 is wound around the outer wall of the stepped convex part 26. To increase the structural stability of the stepped convex part 26, a number of support frames 27 are provided at intervals inside the inner container 2 at positions corresponding to the stepped convex part 26. The middle part of the support frame 27 extends horizontally to form a horizontal part, and both ends of the support frame 27 are symmetrically bent upward to form vertical parts. The vertical parts are tightly fixed on the opposite inner side walls of the inner container 2, so that the support frame 27 can firmly support the internal structure of the inner container 2, and at the same time provide a stable installation foundation for components such as the electromagnetic heating wire 3, and improve the anti-deformation performance of the inner container 2 during the heating process, ensuring the shape and size stability of the inner container 2, thereby ensuring the smoothness of the baking channel 21 and the uniformity of the heating effect, which is beneficial to improving the vulcanization quality of the silicone rubber wire.

[0027] The lower edge of the inner container 2 is turned outwards to form a supporting surface 28. The supporting surface 28 is arranged on the channel steel 5, and the channel steel 5 is arranged on the base 6, effectively improving the stability of the installation of the inner container 2. The box body 1 is fixed to the base 6. Preferably, a layer of aluminum silicate heat-insulating cotton 7 is provided between the supporting surface 28 and the channel steel 5, and a layer of aluminum silicate heat-insulating cotton 7 is provided between the channel steel 5 and the base 6. Utilizing the excellent heat-insulating performance of the aluminum silicate heat-insulating cotton 7, the conduction and dissipation of heat from the bottom of the inner container 2 to the outside are effectively reduced, the energy consumption is lowered, the energy utilization efficiency is improved, and at the same time the external environment is prevented from being affected by high temperature.

[0028] A heat dissipation port is provided on the top surface of the box body 1, and a heat dissipation fan 4 is provided on the heat dissipation port. Temperature probes are provided both inside the box body 1 and on the inner container 2. When the temperature detected by the temperature probe is higher than the predetermined temperature, it is fed back to the temperature controller, and the temperature controller drives the heat dissipation fan 4 to rotate, thereby discharging the hot air inside the box body 1, effectively controlling the temperature inside the oven, avoiding problems such as equipment damage caused by excessive temperature or over-vulcanization of the silicone rubber wire, and ensuring the stable operation of the oven and the quality stability of the product.

[0029] A side mounting rack 5 is provided on the outer wall of the box body 1, increasing the functional expandability and operation convenience of the oven, facilitating the user to install and configure relevant equipment according to actual needs, and improving the practicality and ease of use of the equipment.

[0030] During operation, the electromagnetic induction principle is used to generate heat in the stepped protrusion 26, which then diffuses to the entire inner liner 2, raising the temperature throughout the inner liner 2 and thus heating and vulcanizing the silicone rubber wire passing through the baking channel 21. Compared with traditional electric heating tubes, the electromagnetic heating wire 3 has higher heating efficiency, can raise the temperature more quickly, reduce heat loss, and lower energy consumption. Moreover, the electromagnetic heating wire 3 is wound around the inner liner 2, ensuring uniform heating and distributing heat more evenly within the baking channel 21, resulting in better heating performance.
