Description

Technical Field

[0001] This utility model relates to the field of silicone oil production technology, and in particular to an auxiliary heating device for silicone oil production. Background Technology

[0002] Polyurethane silicone oil, also known as polyurethane foam stabilizer, undergoes heat treatment during its production process. This is done by adding the raw materials into a heat-conducting box, where heating pipes installed within the box's inner wall heat the materials. Existing heating devices for polyurethane silicone oil production have a relatively simple structure, resulting in uneven heating of the raw materials within the heat-conducting box and reduced product quality.

[0003] The utility model patent with publication number CN220187111U provides a heating system for the production of polyurethane silicone oil. While heating the raw materials in the heat-conducting box using heating tubes, the drive motor is started, and the stirring shaft drives the stirring fan blades to rotate inside the heat-conducting box to stir the raw materials. This is beneficial for the uniform heating of the raw materials. During the stirring process, auxiliary heating tubes are used to assist in heating the raw materials, further improving the heating effect of the raw materials. This makes the raw materials in the heat-conducting box more uniformly heated and improves the quality of the finished product.

[0004] However, the auxiliary heating tube in the above scheme is fixedly installed in the heat conduction box, and the position of the auxiliary heating tube cannot be adjusted, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary heating device for silicone oil production, which solves the problem that the auxiliary heating tube is fixedly installed in the heat conduction box and its position cannot be adjusted, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides an auxiliary heating device for silicone oil production, including a heat-conducting box and an auxiliary heating assembly. The auxiliary heating assembly includes a rotating shaft, an elastic telescopic rod, a U-shaped mounting bracket, and a heating wire. The rotating shaft is rotatably connected to the heat-conducting box and is located inside the heat-conducting box. One end of the elastic telescopic rod is fixedly connected to the rotating shaft and is laterally arranged on the side of the rotating shaft. The end of the elastic telescopic rod away from the rotating shaft is fixedly connected to the U-shaped mounting bracket. Both ends of the heating wire are fixedly connected to the upper and lower ends of the U-shaped mounting bracket, respectively, and the heating wire is located inside the U-shaped mounting bracket.

[0007] The elastic telescopic rod includes an outer cylinder, a spring, and an inner cylinder. One end of the outer cylinder is fixedly connected to the rotating shaft, and the outer cylinder has a mounting cavity. The inner cylinder is slidably connected to the outer cylinder. The end of the inner cylinder near the outer cylinder is located inside the mounting cavity, and the end of the inner cylinder away from the outer cylinder is fixedly connected to the U-shaped mounting bracket. The two ends of the spring are fixedly connected to the inner cylinder and the outer cylinder, respectively, and the spring is located inside the mounting cavity.

[0008] The auxiliary heating component further includes a stirring structure, which is spaced apart from the elastic telescopic rod. The stirring structure includes a U-shaped outer frame and multiple fixed blades. The upper and lower ends of the U-shaped outer frame are fixedly connected to the rotating shaft, and the U-shaped outer frame is located on the side of the rotating shaft. The multiple fixed blades are fixedly connected to the U-shaped outer frame, and the multiple fixed blades are spaced apart on the inner side of the U-shaped outer frame.

[0009] The stirring structure further includes multiple rotating blades, which are rotatably connected to the fixed blades and are sleeved on the outside of the fixed blades.

[0010] The fixed blade is provided with a mounting shaft, and the rotating blade has a mounting groove adapted to the mounting shaft, with the mounting shaft passing through the interior of the mounting groove.

[0011] This utility model discloses an auxiliary heating device for silicone oil production. When the silicone oil is being heated, the rotating shaft causes the heating wire to rotate inside the heat-conducting box. As the U-shaped mounting bracket rotates, centrifugal force stretches the elastic telescopic rod. The faster the rotating shaft rotates, the longer the elastic telescopic rod is stretched, thereby adjusting the position of the heating wire within the heat-conducting box. This improves the device's practicality and solves the problem of poor usability caused by the auxiliary heating tube being fixedly installed in the heat-conducting box and its position being unadjustable.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an auxiliary heating device for silicone oil production according to this utility model. Figure 2 This is a structural cross-sectional view of the elastic telescopic rod of an auxiliary heating device for silicone oil production according to this utility model. Figure 3 This is a cross-sectional view of the stirring structure of an auxiliary heating device for silicone oil production according to this utility model.

[0019] This utility model provides an auxiliary heating device for silicone oil production, including a heat conduction box 100 and an auxiliary heating component. The auxiliary heating component includes a rotating shaft 210, an elastic telescopic rod, a U-shaped mounting bracket 220, an electric heating wire 230, and a stirring structure. The elastic telescopic rod includes an outer cylinder 240, a spring 250, and an inner cylinder 260. The stirring structure includes a U-shaped outer frame 310, multiple fixed blades 320, and multiple rotating blades 330.

[0020] In this specific embodiment, the rotating shaft 210 is rotatably connected to the heat-conducting box 100, and the rotating shaft 210 is located inside the heat-conducting box 100. One end of the elastic telescopic rod is fixedly connected to the rotating shaft 210, and the elastic telescopic rod is laterally arranged on the side of the rotating shaft 210. The end of the elastic telescopic rod away from the rotating shaft 210 is fixedly connected to the U-shaped mounting bracket 220. Both ends of the heating wire 230 are fixedly connected to the upper and lower ends of the U-shaped mounting bracket 220, respectively, and the heating wire 230 is located inside the U-shaped mounting bracket 220. The rotating shaft 210 can rotate under the drive of a motor. The elastic telescopic rod is arranged on the side of the rotating shaft 210, so that the rotating shaft 210 can drive the elastic telescopic rod to rotate. The elastic telescopic rod is elastic, so that the length of the elastic telescopic rod can be adjusted. The U-shaped mounting bracket 220 is used to install the heating wire 230. The heating wire 230 generates heat when energized, thereby providing auxiliary heating for the silicone oil. When the silicone oil is being heated, the rotating shaft 210 rotates, causing the heating wire 230 to rotate inside the heat-conducting box 100. When the U-shaped mounting bracket 220 rotates, the elastic telescopic rod is stretched under the action of centrifugal force. The faster the rotating shaft 210 rotates, the longer the elastic telescopic rod is stretched, thereby adjusting the position of the heating wire 230 in the heat-conducting box 100. This allows the position of the heating wire 230 to be adjusted, improving its practicality. This solves the problem that the auxiliary heating tube is fixedly installed in the heat-conducting box 100, making its position unadjustable and resulting in poor practicality.

[0021] Furthermore, one end of the outer cylinder 240 is fixedly connected to the rotating shaft 210, the outer cylinder 240 has a mounting cavity 241, the inner cylinder 260 is slidably connected to the outer cylinder 240, the end of the inner cylinder 260 near the outer cylinder 240 is located inside the mounting cavity 241, the end of the inner cylinder 260 away from the outer cylinder 240 is fixedly connected to the U-shaped mounting bracket 220, and the two ends of the spring 250 are fixedly connected to the inner cylinder 260 and the outer cylinder 240 respectively, the spring 250 is located inside the mounting cavity 241. The mounting cavity 241 is used to mount the spring 250. The spring 250 pulls the inner cylinder 260, causing one end of the inner cylinder 260 to be pulled into the mounting cavity 241. When the rotating shaft 210 rotates, the inner cylinder 260 slides out of the mounting cavity 241 under the pull of the U-shaped mounting bracket 220, thereby extending the length of the entire elastic telescopic rod, and thus moving the heating wire 230 away from the rotating shaft 210, thereby adjusting the position of the heating wire 230.

[0022] Specifically, the stirring structure is spaced apart from the elastic telescopic rod. The upper and lower ends of the U-shaped outer frame 310 are fixedly connected to the rotating shaft 210, and the U-shaped outer frame 310 is located on the side of the rotating shaft 210. Multiple fixed blades 320 are fixedly connected to the U-shaped outer frame 310, and the multiple fixed blades 320 are spaced apart on the inner side of the U-shaped outer frame 310. The stirring structure is used to stir the silicone oil inside the heat-conducting box 100, thereby making the silicone oil in the heat-conducting box 100 more evenly heated. The U-shaped outer frame 310 is used to install the fixed blades 320. Multiple fixed blades 320 are spaced apart on the inner side of the U-shaped outer frame 310. The fixed blades 320 rotate inside the heat conduction box 100 under the drive of the rotating shaft 210, thereby stirring the silicone oil in the heat conduction box 100. The multiple fixed blades 320 are spaced apart, so that the silicone oil can pass between two fixed blades 320, reducing friction and making the rotation of the rotating shaft 210 easier.

[0023] The rotating blade 330 is rotatably connected to the fixed blade 320, and the rotating blade 330 is sleeved on the outside of the fixed blade 320. The fixed blade 320 is provided with a mounting shaft 321, and the rotating blade 330 has a mounting groove 331 adapted to the mounting shaft 321, with the mounting shaft 321 passing through the interior of the mounting groove 331. Multiple rotating blades 330 are rotatably mounted on the fixed blade 320. When the fixed blade 320 rotates around the rotating shaft 210, the rotating blades 330 can rotate around the fixed blade 320, further improving the stirring ability of the silicone oil and making the silicone oil heated more evenly. The rotating blades 330 can rotate around the mounting shaft 321, and the mounting shaft 321 and the mounting groove 331 cooperate to realize the rotatable connection between the rotating blades 330 and the fixed blade 320.

[0024] When using an auxiliary heating device for silicone oil production to assist in heating the silicone oil, the rotation of the rotating shaft 210 causes the heating wire 230 to rotate inside the heat conduction box 100. When the U-shaped mounting bracket 220 rotates, the elastic telescopic rod is stretched under centrifugal force. The faster the rotating shaft 210 rotates, the longer the elastic telescopic rod is stretched, thereby adjusting the position of the heating wire 230 in the heat conduction box 100, improving practicality. Simultaneously, the fixed blades 320 rotate inside the heat conduction box 100 under the drive of the rotating shaft 210, stirring the silicone oil in the heat conduction box 100. The multiple fixed blades 320 are spaced apart, allowing the silicone oil to pass between two fixed blades 320, reducing friction and making the rotation of the rotating shaft 210 easier.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
