Description

Technical Field

[0001] This utility model relates to the production of cross-linked cable materials, and more particularly to a mixing device for the production of cross-linked cable materials. Background Technology

[0002] Cross-linked cable material is a polymer material used to manufacture the insulation layer or sheath of cross-linked power cables. It forms a three-dimensional network structure (cross-linking) between linear polymer chains through chemical or physical methods, thereby significantly improving the temperature resistance, mechanical strength and electrical performance of the cable.

[0003] Mixing is an important step in the production of cross-linked cable materials. However, the mixing equipment is prone to causing the raw materials to adhere to the inner wall during mixing. At the same time, the mixing equipment is prone to large resistance during mixing, resulting in poor flowability of the raw materials and poor mixing uniformity. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a mixing device for the production of cross-linked cable materials, which not only facilitates the scraping off of raw materials adhering to the inner wall, but also facilitates the reduction of resistance.

The stator of the motor is connected to the vessel body, and the rotor of the motor is connected to the rotating shaft. The mixing units are correspondingly connected to the connecting rods. The first support plate and the second support plate are both connected to the rotating shaft via the connecting rods. Several first scrapers are spaced apart on the first support plate, and several second scrapers are spaced apart on the second support plate. The first scrapers and the second scrapers are staggered and all abut against the inner wall of the vessel body.

[0006] Optionally, the hybrid component further includes: A plurality of first through holes are spaced apart in the first bearing plate; A plurality of second through holes are spaced apart on the second bearing plate.

[0007] Optionally, both the first through hole and the second through hole have circular cross-sectional shapes.

[0008] Optional, also includes: Heating tubes wound around the outside of the vessel body; A temperature sensor, wherein the sensing end of the temperature sensor is located inside the vessel; A controller that is electrically connected to both the heating element and the temperature sensor.

[0009] Optionally, it also includes a heat insulation layer wrapped around the outside of the vessel, with the heating tube located inside the heat insulation layer.

[0010] Optionally, it may also include an inert gas supply assembly in communication with the vessel body.

[0011] Optionally, it also includes an air inlet and an air outlet, both located on the vessel body, and the inert gas supply assembly is connected to both the air inlet and the air outlet.

[0012] Optionally, the mixing unit includes: A hybrid blade, one end of which is connected to the connecting rod; A mixing ball connected to the other end of the mixing blade.

[0013] Beneficial effects: (1) Since several first scrapers and several second scrapers are staggered and all of them are in contact with the inner wall of the vessel, it is convenient to alternately scrape off the raw materials adhering to the inner wall of the vessel; (2) Since several first scrapers are connected to the first bearing plate at intervals and second scrapers are connected to the second bearing plate at intervals, there is a gap between adjacent first scrapers and between adjacent second scrapers, which makes it easier to reduce the resistance of the mixing component, thereby making the raw material flow better and the mixing uniformity better.

[0017] Example 1 like Figure 1 This embodiment provides a mixing device for cross-linked cable material production, including: a vessel body 1 having an inlet 11 and an outlet 12; a mixing component 2 including a motor 21, and also including a rotating shaft 22, a plurality of connecting rods 23, a plurality of mixing units 24, a first support plate 25, and a second support plate 26, all located within the vessel body 1. The stator of the motor 21 is connected to the vessel body 1, and the rotor of the motor 21 is connected to the rotating shaft 22. The mixing units 24 are correspondingly connected to the connecting rods 23. The first support plate 25 and the second support plate 26 are both connected to the rotating shaft 22 through the connecting rods 23. A plurality of first scrapers 251 are spaced apart on the first support plate 25, and a plurality of second scrapers 261 are spaced apart on the second support plate 26. The plurality of first scrapers 251 and the plurality of second scrapers 261 are staggered and all abut against the inner wall of the vessel body 1.

[0018] Specifically, the feed inlet 11 facilitates the entry of raw materials such as base resin, stabilizer, antioxidant, and crosslinking agent into the reactor body 1; the discharge outlet 12 facilitates the discharge of raw materials from the reactor body 1; the rotor of the motor 21 drives the rotating shaft 22, connecting rod 23, mixing unit 24, first bearing plate 25, second bearing plate 26, first scraper 251, and second scraper 261 to rotate, and the motor 21 can be a stepper motor, servo motor, etc.; the rotating shaft 22 is used to support the connecting rod 23, etc., and the rotating shaft 22 and the rotor of the motor 21 can be connected by a coupling 27; the connecting rod 23 is used to support the mixing unit 24, the first bearing plate 25, the second bearing plate 26, the first scraper 251, and the second scraper 261. 5 and the second support plate 26, etc.; the mixing unit 24 is used to mix raw materials; since a number of first scrapers 251 and a number of second scrapers 261 are staggered and all abut against the inner wall of the vessel body 1, it is convenient to alternately scrape off the raw materials attached to the inner wall of the vessel body 1. Since a number of first scrapers 251 are spaced apart on the first support plate 25 and the second scrapers 261 are spaced apart on the second support plate 26, there is a gap between adjacent first scrapers 251 and adjacent second scrapers 261, which makes it easier to reduce the resistance of the mixing component 2, thereby making the flow of raw materials good and the mixing uniformity good.

[0019] Furthermore, such as Figure 1 The mixing component 2 further includes: a plurality of first through holes 252 spaced apart on the first support plate 25; and a plurality of second through holes 262 spaced apart on the second support plate 26.

[0020] Specifically, the first through hole 252 and the second through hole 262 help reduce the resistance of the first support plate 25 and the second support plate 26, thereby further improving the flowability of raw materials and further improving the uniformity of mixing.

[0021] Furthermore, such as Figure 1 The cross-sectional shape of the first through hole 252 and the second through hole 262 is circular.

[0022] Specifically, the cross-sectional shape is circular, which not only facilitates processing but also ensures good uniformity of stress on the first bearing plate 25 and the second bearing plate 26.

[0023] Furthermore, such as Figure 1 It also includes: a heating tube 3 wrapped around the outside of the vessel body 1; a temperature sensor, the detection end of which is located inside the vessel body 1; and a controller that is electrically connected to both the heating tube 3 and the temperature sensor.

[0024] Specifically, the controller, together with the heating tube 3 and the temperature sensor, is used to control the temperature of the vessel 1 to ensure the mixing performance of the raw materials. The heating tube 3 can be made of nickel-chromium alloy, iron-chromium-aluminum alloy, etc., and the temperature sensor can be thermocouple type, resistance temperature detector type, etc.

[0025] Furthermore, such as Figure 1 It also includes a heat insulation layer 4 wrapped around the vessel body 1, with the heating tube 3 located inside the heat insulation layer 4.

[0026] Specifically, insulation layer 4 is used for heat preservation, and the material of insulation layer 4 can be rock wool, glass wool, etc.

[0027] Furthermore, such as Figure 1 It also includes an inert gas supply assembly connected to the vessel body 1.

[0028] Specifically, the inert gas supply component is used to introduce inert gas (such as nitrogen) into the vessel 1 to remove oxygen and moisture, thereby preventing the raw materials from oxidizing, degrading, or prematurely cross-linking during the high-temperature mixing process.

[0029] Furthermore, such as Figure 1 It also includes an air inlet 13 and an air outlet 14, both located in the vessel body 1, and the inert gas supply component is connected to the air inlet 13 and the air outlet 14.

[0030] Furthermore, such as Figure 1 The mixing unit 24 includes: a mixing blade 241, one end of which is connected to a connecting rod 23; and a mixing ball 242 connected to the other end of the mixing blade 241.

[0031] Specifically, the mixing blade 241 is used for stirring and mixing; the mixing ball 242 is used to break up lumpy raw materials to facilitate increased stirring and mixing performance.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
