Description

Technical Field

[0001] This utility model relates to the field of self-regulating heating cable technology, specifically to a radiation emulsion processing device for the production of self-regulating heating cables. Background Technology

[0002] Self-regulating heating cables are widely used in building heating, pipeline antifreeze, and agricultural greenhouses due to their ability to automatically regulate heat output. As the core raw material for producing self-regulating heating cables, the uniformity of mixing of the radiation emulsion during processing directly affects the cable's conductivity, temperature control stability, and service life. Insufficient mixing can lead to problems such as localized overheating and reduced heating efficiency, and may even cause safety accidents.

[0003] Currently, traditional radiation emulsion mixing and processing equipment generally adopts a single stirring blade or a simple mechanical stirring structure. This single stirring method can only achieve unidirectional stirring of local materials, which is difficult to penetrate the deep layers of the emulsion. This results in the formation of mixing blind zones in the mixing tank, making it impossible to achieve full mixing in all directions and at multiple levels. Consequently, the components in the emulsion are unevenly distributed, affecting the quality of the final product.

[0004] Therefore, it is necessary to modify it by setting up a three-dimensional mixing system through the coordinated operation of conveying fan blades, mixing fan blades, and agitating fan blades. This system enables the vertical conveying and horizontal and top-level mixing of materials, eliminating blind spots in the mixing process. It also allows for thorough mixing of the radiation emulsion in all directions and at multiple levels, resulting in uniform distribution of all components in the emulsion and improved product quality. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a radiant emulsion processing device for the production of self-regulating heating cables. This device features a three-dimensional stirring system formed by the coordinated operation of conveying fan blades, mixing fan blades, and agitating fan blades. This system enables vertical and horizontal mixing of materials, eliminating mixing blind spots. It achieves thorough mixing of the radiant emulsion in all directions and at multiple levels, resulting in uniform distribution of components and improved product quality. This solves the problem that single-mode stirring only achieves unidirectional agitation of materials in a localized area, making it difficult to penetrate deep into the emulsion. This leads to mixing blind spots within the mixing chamber, preventing thorough mixing in all directions and at multiple levels, resulting in uneven distribution of components in the emulsion and affecting the final product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a radiation emulsion processing device for the production of self-limiting heating cables, comprising a mixing tank, a drive motor fixedly connected to the bottom of the mixing tank via a bracket, the output end of the drive motor penetrating into the interior of the mixing tank and fixedly connected to a conveying fan rod, a conveying cylinder sleeved on the surface of the conveying fan rod fixedly connected to the bottom of the inner wall of the mixing tank, a plurality of evenly distributed inlets being opened at the bottom of the conveying cylinder, a follower rod fixedly connected to the top of the conveying fan rod, the top of the follower rod being rotatably connected to the top of the inner wall of the mixing tank, transverse rods fixedly connected to the left and right sides below the surface of the follower rod, an outer swing rod rotatably connected to the lower part of the outer end of the transverse rod located outside the conveying cylinder, a plurality of evenly distributed mixing fan blades fixedly connected to the surface of the outer swing rod, a plurality of evenly distributed agitating fan blades fixedly connected to the upper part of the surface of the follower rod, a feeding valve pipe connected to the left side of the top of the mixing tank, and a discharge valve pipe connected to the bottom of the mixing tank.

[0007] In a preferred embodiment of this invention, a stabilizing block is rotatably connected to the bottom of the outer swing rod, and an annular guide rail is fixedly connected to the outer side of the bottom of the mixing tank inner wall. The bottom of the stabilizing block is slidably connected to the top of the annular guide rail.

The upper part of the inner side of the rubber scraper is fixedly connected to the outer end of the horizontal rod through a first connecting rod, and the lower part of the inner side of the rubber scraper is fixedly connected to the outer side of the stabilizing block through a second connecting rod.

[0009] In a preferred embodiment of this invention, a sealed bearing is fixedly connected to the surface of the output end of the drive motor, the surface of the sealed bearing is fixedly connected to the inner wall of the mixing tank, a bearing seat is fixedly connected to the top of the inner wall of the mixing tank, and the top end of the follower rod is fixedly connected to the inner wall of the bearing seat.

[0010] As a preferred embodiment of this invention, a circulation pump is fixedly connected to the right side of the mixing tank. The input end of the circulation pump is connected to the lower right side of the mixing tank through a first connecting pipe, and the output end of the circulation pump is connected to the top of the mixing tank through a second connecting pipe.

[0011] As a preferred embodiment of this utility model, the front of the mixing box is provided with an observation slot, and the inside of the observation slot is provided with transparent explosion-proof glass. Sealing strips are fixedly connected to all four sides of the transparent explosion-proof glass, and the surface of the sealing strips is fixedly connected to the inner wall of the observation slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a drive motor to rotate the conveyor blade rod, and the conveyor cylinder, in conjunction with the feed inlet, can convey the material at the bottom of the mixing tank upwards, achieving material circulation. The horizontal rod, the outer swing rod, and the mixing blade on the follower rod can horizontally agitate the material outside the conveyor cylinder. The stirring blade can stir the material at the top of the mixing tank. The conveyor blade rod, the mixing blade, and the stirring blade work together to form a three-dimensional stirring system, which changes the limitation of traditional single stirring blades or simple mechanical stirring structures that can only achieve local unidirectional stirring of materials. It effectively penetrates the deep layer of the emulsion, eliminates mixing blind spots, and achieves full mixing of materials in all directions and at multiple levels. This makes the components in the emulsion evenly distributed, thereby improving the quality of the radiation emulsion used in the production of self-regulating heating cables, ensuring the conductivity, temperature control stability, and service life of the cables, and reducing safety hazards such as local overheating and reduced heating efficiency caused by insufficient mixing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a radiation emulsion processing device for the production of self-limiting heating cables, including a mixing tank 1. A drive motor 2 is fixedly connected to the bottom of the mixing tank 1 via a bracket. The output end of the drive motor 2 passes through the interior of the mixing tank 1 and is fixedly connected to a conveying fan rod 3. A conveying cylinder 4, sleeved on the surface of the conveying fan rod 3, is fixedly connected to the bottom of the inner wall of the mixing tank 1. Several evenly distributed inlet ports 5 are opened at the bottom of the conveying fan rod 3. A follower rod 6 is fixedly connected to the top of the conveying fan rod 3. The top of the follower rod 6 is rotatably connected to the top of the inner wall of the mixing tank 1. Horizontal rods 7 are fixedly connected to the left and right sides below the surface of the follower rod 6. An outer swing rod 8 located outside the conveying cylinder 4 is rotatably connected to the lower part of the outer end of the horizontal rod 7. Several evenly distributed mixing fan blades 9 are fixedly connected to the surface of the outer swing rod 8. Several evenly distributed agitating fan blades 10 are fixedly connected to the upper part of the surface of the follower rod 6. A feeding valve pipe 11 is connected to the left side of the top of the mixing tank 1, and a discharge valve pipe 12 is connected to the bottom of the mixing tank 1.

[0022] refer to Figure 4 The bottom of the outer swing arm 8 is rotatably connected to a stabilizing block 13, and the outer side of the bottom of the mixing box 1 is fixedly connected to an annular guide rail 14. The bottom of the stabilizing block 13 is slidably connected to the top of the annular guide rail 14.

[0023] As a technical optimization of this utility model, by setting a stabilizing block 13 rotatably connected to the bottom of the outer swing rod 8 and cooperating with the annular guide rail 14, a stable support and guiding function is provided for the outer swing rod 8 when the mixing fan blade 9 horizontally agitates the material; this allows the outer swing rod 8 to remain stable during rotation, avoiding swaying or deviation, ensuring the uniform mixing effect of the mixing fan blade 9 on the material, further improving the stability and reliability of mixing, ensuring that the material can be fully and stably mixed in the horizontal direction, and helping to improve the mixing quality of the radiation emulsion.

[0024] refer to Figure 2 Rubber scrapers 15 are attached to both the left and right sides of the inner wall of the mixing box 1. The upper part of the inner side of the rubber scraper 15 is fixedly connected to the outer end of the horizontal rod 7 through the first connecting rod, and the lower part of the inner side of the rubber scraper 15 is fixedly connected to the outer side of the stabilizing block 13 through the second connecting rod.

[0025] As a technical optimization of this utility model, a rubber scraper 15 is provided that adheres to the inner wall of the mixing tank 1. The top end of the scraper is connected to the horizontal rod 7 via a first connecting rod, and the bottom end is connected to the stabilizing block 13 via a second connecting rod. During the rotation of the mixing fan blade 9, the rubber scraper 15 moves synchronously. The rubber scraper 15 can adhere tightly to the inner wall of the mixing tank 1, scraping off the emulsion adhering to the inner wall of the mixing tank 1, avoiding material residue, so that the emulsion can fully participate in the mixing, improving the integrity and uniformity of the mixing, preventing the imbalance of the proportions of the emulsion components due to material residue on the inner wall, thereby improving the quality of the final product.

[0026] refer to Figure 2 A sealed bearing 16 is fixedly connected to the surface of the output end of the drive motor 2. The surface of the sealed bearing 16 is fixedly connected to the inner wall of the mixing box 1. A bearing seat 17 is fixedly connected to the top of the inner wall of the mixing box 1. The top end of the follower rod 6 is fixedly connected to the inner wall of the bearing seat 17.

[0027] As a technical optimization of this utility model, by setting a sealed bearing 16 at the output end of the drive motor 2, the leakage of emulsion in the mixing tank 1 can be effectively prevented, ensuring the sealing of the mixing tank 1 and avoiding material leakage that would cause waste and pollution. At the same time, it also ensures the normal operating environment of the drive motor 2. The bearing seat 17 at the top of the inner wall of the mixing tank 1 cooperates with the follower rod 6, providing stable support and rotation conditions for the follower rod 6, reducing friction and resistance during the rotation of the follower rod 6, so that the follower rod 6 can drive the transverse rod 7, the outer swing rod 8, the mixing fan blade 9 and the tug fan blade 10 to rotate more smoothly, ensuring the stability and efficiency of the mixing process, reducing the wear and failure rate of the equipment, and extending the service life of the equipment.

[0028] refer to Figure 2 A circulation pump 18 is fixedly connected to the right side of the mixing tank 1. The input end of the circulation pump 18 is connected to the lower right side of the mixing tank 1 through the first connecting pipe 19, and the output end of the circulation pump 18 is connected to the top of the mixing tank 1 through the second connecting pipe 20.

[0029] As a technical optimization of this utility model, by setting up a circulation pump 18 and connecting it to the mixing tank 1 via a first connecting pipe 19 and a second connecting pipe 20, the emulsion at the bottom of the mixing tank 1 can be extracted and transported to the top, realizing the circulation of the emulsion within the mixing tank 1; this further enhances the mixing effect of the materials, allowing the emulsion to be more fully stirred and mixed during the circulation process, compensating for the areas of insufficient mixing that may exist when relying solely on the stirring components, improving the uniformity and efficiency of emulsion mixing, and helping to produce radiation emulsions of higher quality.

[0030] refer to Figure 1The front of the mixing box 1 is provided with an observation slot, and the inside of the observation slot is provided with transparent explosion-proof glass 21. The transparent explosion-proof glass 21 is fixedly connected with sealing strips 22 on all four sides, and the surface of the sealing strips 22 is fixedly connected to the inner wall of the observation slot.

[0031] As a technical optimization of this utility model, by setting an observation slot and a transparent explosion-proof glass 21 on the front of the mixing tank 1, the operator can easily observe the mixing state of the emulsion inside the mixing tank 1 at any time and keep track of the mixing process and effect. The setting of the sealing strip 22 ensures the sealing of the observation slot, preventing emulsion leakage and external impurities from entering the mixing tank 1. This not only ensures the safety of the operator, but also ensures that the mixing process is not disturbed by the outside world, thus guaranteeing the quality of emulsion mixing and the cleanliness of the environment.

[0032] The working principle and usage process of this utility model are as follows: During use, check whether the mixing tank 1, drive motor 2, circulating pump 18, and other components are securely installed, and whether the sealing components such as the sealing bearing 16 and sealing strip 22 are intact. Add various raw materials required for radiation emulsion processing to the mixing tank 1 through the feeding valve pipe 11. Turn on the drive motor 2. After the drive motor 2 starts, its output end drives the conveying fan blade rod 3 to rotate. During the rotation of the fan blades on the surface of the conveying fan blade rod 3, the material located at the bottom inlet 5 of the conveying cylinder 4 is conveyed upwards using centrifugal force and the pushing action of the blades, thus achieving upward material conveying. The lower circulation motion is simultaneously controlled by the follower rod 6, which is fixedly connected to the conveying fan blade rod 3. The horizontal rod 7 on the follower rod 6 drives the outer swing rod 8 and the mixing fan blade 9 to horizontally agitate the material outside the conveying cylinder 4. Meanwhile, the agitator fan blade 10 above the surface of the follower rod 6 stirs the material at the top of the mixing tank 1. At the same time, the circulation pump 18 is started to circulate the emulsion in the mixing tank 1, which enhances the mixing effect. The operator can observe the mixing state of the emulsion in the mixing tank 1 in real time through the transparent explosion-proof glass 21 in the front of the mixing tank 1, and judge the degree and uniformity of the emulsion mixing. If any abnormalities are found, such as shaking of the stirring components or uneven mixing of the emulsion, stop the machine immediately for inspection and adjustment. Once the emulsion reaches the required level of uniformity, turn off the drive motor 2 and the circulation pump 18 to stop stirring and circulation. Open the discharge valve pipe 12 to discharge the mixed radiant emulsion from the mixing tank 1 for subsequent production of self-regulating heating cables. After the mixing process is completed, clean the inside of the mixing tank 1 to remove any residual emulsion and check all components for damage or wear. If necessary, repair or replace them promptly to prepare for the next use.
