Technical Field

[0001] The utility model relates to the field of thermoplastic marking paint constant temperature tanks, and particularly relates to an automatic constant temperature tank for thermoplastic marking paint. Background Technique

[0002] The thermoplastic marking paint constant temperature tank, a storage and heating device designed specifically for thermoplastic road marking paint, has the ability to precisely control the internal temperature. It ensures that the paint remains in a liquid state at the optimal temperature, facilitating the smooth progress of construction operations. To achieve this goal, the constant temperature tank uses internal heating elements or external heat sources to ensure uniform heating of the paint, effectively preventing local overheating and caking.

[0003] However, in the actual use process, the automatic constant temperature tank for thermoplastic marking paint faces a challenge: the heat preservation performance of the tank body has limitations. Although equipped with a heat preservation sleeve to assist in maintaining temperature stability, after long-term use, the temperature still inevitably drops slowly, thereby affecting the constant temperature effect and making it difficult to reach the ideal state. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an automatic constant temperature tank for thermoplastic marking paint, which can effectively solve the problems raised in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] Heat preservation filler is injected into the clamping cavity, and the heat preservation filler realizes the heat preservation of the tank body.

[0009] As a further preferred scheme of the utility model, the constant temperature heat preservation cover is divided into two half covers. Installation blocks are arranged at the edges of the half covers, and installation holes are formed on the installation blocks.

[0016] The design of the two semi-cover structures of the constant temperature heat preservation cover makes the fixing and disassembly of the heat preservation cover simple through the installation blocks and installation holes, improving the flexibility and applicability of the heat preservation cover. The split design and easily detachable structure of the constant temperature heat preservation cover enable convenient cleaning and maintenance after the coating is used up, ensuring the long-term stable operation of the equipment.

Specific implementation mode

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific implementation modes.

[0025] Embodiment 1

[0026] As Figures 1 to 5 shown, we introduced an automatic constant temperature tank for paint designed specifically for hot melt road markings, with a detailed structure and perfect functions. The constant temperature tank mainly consists of the following key parts, and corresponding numerical markings are attached for easy identification: tank body 1, tank cover 2, auxiliary material adding pipe 3, sealing cover 4, constant temperature heating component 5, feeding pipeline 6, and an external constant temperature insulation cover 7.

[0027] The tank body 1, as the main structure, is provided with tank covers 2 at both ends, facilitating the closing and opening of the paint. On the tank cover 2, we cleverly installed an auxiliary material adding pipe 3 to add auxiliary materials into the tank when needed. At the same time, a feeding pipeline 6 and a sealing cover 4 are provided on the side wall of the tank body 1. The feeding pipeline 6 is responsible for the input of the paint, while the sealing cover 4 ensures the sealing of the tank body 1 during the heating process.

[0028] In order to achieve the constant temperature heating of the paint, we installed a constant temperature heating component 5 on the sealing cover 4. This component can precisely control the temperature inside the tank body 1 to ensure that the paint is always in the best working state.

[0029] To further improve the heat preservation effect, we sleeved a constant temperature insulation cover 7 on the outer wall of the tank body 1. An clamping cavity 10 is formed on the inner wall of the insulation cover. A spiral pipeline 9 is installed in the clamping cavity 10. Both ends of the spiral pipeline 9 are connected to the hot water inlet and outlet pipeline 8. These pipelines pass through the insulation cover and are connected to an external hot water circulation device. When hot water flows through the spiral pipeline 9, it can effectively heat the insulation cover, thereby realizing the constant temperature heat preservation of the tank body 1.

[0030] In addition, a heat-insulating filler 11 is injected into the sandwich cavity 10. This filler has good heat-insulating performance and can further reduce heat dissipation. The heat-insulating filler 11 can be selected from high-quality materials such as polyurethane foaming agent, molded polystyrene foam, extruded polystyrene foam or expanded perlite.

[0031] The sealing cover 4 and the tank body 1 are integrally designed to ensure the structural stability. The constant-temperature heating component 5 is installed on the sealing cover 4 by bolts, which is convenient for installation and disassembly. The constant-temperature heat-insulating cover 7 is adapted to the sealing cover 4 and the feeding pipeline 6, and a heat-insulating rubber ring is provided at the connection to enhance the sealing performance and heat-insulating effect.

[0032] The spiral pipeline 9 and the hot water inlet and outlet pipeline 8 are integrally designed to ensure the smooth flow of hot water. The spiral design of the spiral pipeline 9 increases the contact area with the inner wall of the sandwich cavity 10, improving the heating efficiency. At the same time, rubber strips are provided on the pipeline surface, and the rubber strips are pressed against the inner wall of the sandwich cavity 10 to further enhance the heat-insulating effect.

[0033] The constant-temperature heat-insulating cover 7 is divided into an inner cover and an outer cover. The inner cover is made of heat-conducting material and is closely attached to the tank body 1, which can quickly transfer heat to the tank body 1. The outer cover plays a role in protecting the inner cover and enhancing the heat-insulating effect. The two form a closed cover structure through the rings at both ends, ensuring the effective transfer of heat and the durability of the heat-insulating effect.

[0034] Embodiment 2

[0035] In Embodiment 2, we also introduce a coating automatic constant-temperature tank for hot-melt road markings, whose structure is basically the same as that in Embodiment 1. However, there is an innovation in the design of the constant-temperature heat-insulating cover 7. Specifically, the constant-temperature heat-insulating cover 7 is divided into two half-cover structures, and installation blocks 12 are provided at the edges of each half-cover. Installation holes 13 are provided on the installation blocks 12. By inserting bolts into these holes and sleeving nuts, the fixation and disassembly of the two half-covers can be easily achieved. This design not only facilitates installation and maintenance but also improves the flexibility and applicability of the constant-temperature heat-insulating cover 7.

[0036] The coating automatic constant-temperature tank provided in this embodiment has the characteristics of compact structure, perfect functions, excellent heat-insulating effect, etc., and can effectively meet the constant-temperature requirements of hot-melt road marking coatings during the heating process.

[0037] Usage process: Ensure that components such as the tank body 1, tank cover 2, constant-temperature heating component 5, and constant-temperature heat-insulating cover 7 of the hot-melt road marking coating automatic constant-temperature tank are in good condition. Check whether the sealing cover 4 is tightly closed to ensure that the coating does not leak during the heating process. Inject the hot-melt road marking coating into the tank body 1 through the feeding pipeline 6. During the input process, pay attention to controlling the flow rate and speed of the coating to avoid the coating from overflowing or splashing.

[0038] Through the auxiliary material adding pipe 3 on the tank cover 2, the required auxiliary materials are added into the tank. These auxiliary materials may include pigments, thickeners, desiccants, etc., which are used to improve the performance of the coating. Start the constant temperature heating component 5 to heat the coating in the tank body 1. The constant temperature heating component 5 can accurately control the temperature in the tank to ensure that the coating remains at a constant temperature at the optimal working temperature.

[0039] At the same time, start the external hot water circulation device to make the hot water flow through the spiral pipeline 9 in the constant temperature heat preservation cover 7. When the hot water circulates in the spiral pipeline 9, it will heat the heat preservation cover, and then keep the tank body 1 at a constant temperature. The spiral design of the spiral pipeline 9 increases the contact area with the inner wall of the clamping cavity 10, improving the heating efficiency. The clamping cavity 10 in the constant temperature heat preservation cover 7 is also filled with heat preservation filling materials 11, such as polyurethane foaming agent, molded polystyrene foam, etc. These materials have good heat preservation performance and can further reduce the heat loss.

[0040] During the heating and heat preservation process of the coating, continuously monitor the temperature in the tank body 1. If it is found that the temperature deviates from the set value, adjust the power of the constant temperature heating component 5 or the flow rate of the hot water circulation device in time to ensure that the coating remains within the optimal working temperature range. Through the synergistic effect of the above steps, the automatic constant temperature tank for hot melt marking paint can achieve continuous constant temperature heating and heat preservation of the paint. This helps to maintain the fluidity and construction performance of the paint, ensuring the quality and efficiency of hot melt marking construction. When the paint is used up, turn off the constant temperature heating component 5 and the hot water circulation device. Open the tank cover 2 and the sealing cover 4, and clean the residual paint in the tank body 1 and the feeding pipeline 6. At the same time, conduct necessary maintenance on the constant temperature heat preservation cover 7 to ensure its long-term stable operation.
