Description

Technical Field

[0001] The invention relates to the technical field of road marking construction equipment, and in particular to a reaction kettle assembly for a concrete placing machine. Background Art

[0003] Road marking is an indispensable and important facility in modern traffic management. It is used to guide, warn and regulate traffic behavior by drawing lines, arrows, text and other signs on the road surface. As an efficient and durable construction method, hot melt road marking technology has been widely used in road construction. This technology heats the hot melt paint to a molten state and uses a feeding mechanism to evenly transport the paint to the construction equipment, thereby forming a road marking with high adhesion and durability.

[0004] In the prior art, hot melt road marking construction equipment usually uses flames to directly heat the outer wall of the paint tank. Although this heating method has a simple structure, the single and uneven heating path causes the paint to be in an unstable molten state. The paint is prone to quality deterioration in the case of local overheating or insufficient heating, which affects the adhesion and durability of the marking. In addition, the heating efficiency is low, the heat loss is serious, the construction time is prolonged, and the energy consumption is high. In the actual construction process, due to the uneven heating of the paint, the thickness and width of the marking are difficult to maintain consistency, which directly affects the clarity and service life of the marking.

[0005] The existing technology lacks a device that can evenly heat the paint tank, and cannot effectively solve the problem of unstable molten state of the paint. This technical problem leads to a decline in the quality of road marking construction, which is manifested in inconsistent thickness and width of the road marking, insufficient adhesion and reduced durability, making it difficult to meet the requirements of high-precision and high-efficiency construction.

[0028] Reference below Figure 1-Figure 4 A reactor assembly for a material distribution machine provided according to an embodiment of the present invention is described. The reactor assembly for the material distribution machine includes: a coating tank 100, which is used to place hot melt coating, and the coating tank 100 is connected to the material distribution machine; a heat transfer oil chamber 200, which is wrapped and arranged at the bottom and side walls of the coating tank 100; a heat transfer structure 500, which is connected to the heat transfer oil chamber 200 and forms a circulation passage; a heating structure, which is used to heat the heat transfer structure 500; an outer wall 600, which forms an internal installation space, and is used to install the coating tank 100, the heat transfer oil chamber 200, the heat transfer structure 500 and the heating structure; wherein the interior of the heat transfer oil chamber 200 and the heat transfer structure 500 are filled with heat transfer oil, and the heat transfer oil flows between the heat transfer structure 500 and the heat transfer oil chamber 200 through the circulation passage. The structure includes a heat transfer oil chamber 200 wrapped around the bottom and side walls of the coating tank 100. The heat transfer oil chamber 200 is connected to the heat transfer structure 500 to form a closed-loop circulation path, and the heat transfer oil is heated by the heating structure to evenly transfer heat to various parts of the coating tank 100. The heat transfer oil is continuously heated by the heating structure, so that the heat transfer oil circulates in the closed-loop path, and the heat is evenly distributed to various areas of the coating tank 100 by utilizing the efficient heat transfer characteristics of the heat transfer oil, while dynamically balancing the overall temperature of the coating tank 100, thereby achieving the effect of uniform heating and stable temperature control.

[0029] Through the above structure, the invention provided by this application effectively solves the problem of coating melting quality caused by local overheating or insufficient heating in the traditional flame direct heating method, ensuring that the coating maintains optimal fluidity and temperature uniformity during the melting process. The uniform heat distribution not only improves the consistency of coating thickness and width during the marking construction process, but also enhances the adhesion and durability of the marking line, significantly improving the construction quality. In addition, the thermal oil circulation system reduces heat waste through efficient heat transfer, greatly reduces energy consumption compared to the traditional flame heating method, and further improves the operating economy and energy-saving and environmental protection performance of the equipment.

[0030] Please continue to participate Figure 4 As shown, according to one embodiment of the present invention, the heating structure includes: a heating baffle 300, which is composed of a top plate 310, a bottom plate 320 and a plurality of side plates 330, and the top plate 310 is in close contact with the heat-conducting structure 500; and a heating device 400, which is used to heat the top plate 310. The heating structure transfers heat to the top plate 310 of the heating baffle 300 through the heating device 400. The top plate 310 is in close contact with the heat-conducting structure 500, and the heat is further transferred to the heat-conducting oil through the heat-conducting structure 500, ensuring that the heat-conducting oil is heated and maintains efficient circulation in the circulation passage. The heat-conducting oil transfers heat evenly to the bottom and side walls of the coating tank 100, thereby achieving temperature-controlled heating of the hot-melt coating. By adopting the structural design of the heating baffle 300, the heat of the heating device 400 can be evenly distributed on the top plate 310, avoiding local overheating and improving the overall heat transfer efficiency.

[0031] This embodiment achieves indirect heating through the heating baffle 300, avoiding direct contact between the heating device 400 and the heat transfer oil, thereby reducing temperature fluctuations and the loss of the heating device 400, and improving the stability and service life of the equipment. In addition, the multi-plate structure design of the heating baffle 300 ensures uniform distribution of heat, effectively improving thermal efficiency and heating uniformity. This design also simplifies the maintenance requirements of the heating device 400, reduces the operating cost of the equipment, and improves the overall heating performance of the paint tank 100.

[0032] It should be noted that the material of the heating baffle 300 can be selected according to actual needs. Metal materials with excellent thermal conductivity, such as copper, stainless steel or aluminum alloy. The close-fitting design between the top plate 310 and the heat-conducting structure 500 can improve the heat transfer efficiency by applying thermal paste or using mechanical fixing methods. The form of the heating device 400 can be selected according to the energy supply conditions. Electric heaters, gas heaters or infrared heaters can be selected to adapt to different usage environments. The shape and size of the baffle can be adjusted according to the specific needs of the paint tank 100 to ensure that the coverage of the heat transfer is maximized and meet the structural requirements of the equipment.

[0033] Please continue to see Figure 1 , Figure 3As shown, according to one embodiment of the present invention, the heating baffle 300 is detachably mounted on the bottom of the heat-conducting structure 500. It is convenient to quickly install or replace when needed. The heating baffle 300 is directly mounted on the bottom of the heat-conducting structure 500, and its top plate 310 is in close contact with the heat-conducting structure 500 to achieve efficient heat transfer. The detachable design is not only convenient for daily cleaning and maintenance of the equipment, but also can be quickly replaced when the heating baffle 300 or the heating device 400 is damaged, reducing downtime and improving the operating efficiency of the equipment.

[0034] Specifically, the above structure improves the maintenance convenience and flexibility of the device. Through the detachable installation design, the user can quickly replace or adjust the heating baffle 300, extending the service life of the entire device. In addition, the structure is easy to clean and can effectively prevent the problem of reduced heat transfer efficiency due to dust and impurities accumulation between the heat-conducting baffle and the heat-conducting structure 500, while further optimizing the working performance and long-term stability of the device.

[0035] It should be noted that the heating baffle 300 can be fixed in a variety of ways, such as bolt fixing, snap-on installation or magnetic adsorption fixing, to adapt to different usage scenarios and maintenance requirements. In addition, the disassembly form of the heating baffle 300 can be achieved by designing modular components, which is convenient for quick disassembly and installation. For special working environments, the heating baffle 300 can be manufactured with materials with better corrosion resistance and high temperature resistance to improve its service life and applicability. The connection method between the heat-conducting structure 500 and the heating baffle 300 can also be adjusted, such as adding flexible gaskets or heat-conducting materials to further improve the heat conduction efficiency and stability.

[0036] Please continue to see Figure 1-3 As shown, according to another embodiment of the present invention, the heat-conducting structure 500 includes: a heat-conducting coil 510, which is arranged on the upper part of the top plate 310, closely attached to the top plate 310, and coiled on the bottom of the heat-conducting oil chamber 200; a connecting pipe 520, which is used to connect the heat-conducting coil 510 and the heat-conducting oil chamber 200; and a circulation pump 530, which is connected to the heat-conducting coil 510 and the connecting pipe 520, and is used to drive the circulation of the heat-conducting oil.

[0037] Specifically, the heat conducting coil 510 is arranged at the bottom of the thermal oil chamber 200, and is designed to be in close contact with the top plate 310 to achieve efficient heat transfer. The circulation pump 530 is responsible for driving the thermal oil to circulate along the connecting pipe 520 and the heat conducting coil 510 to form a closed heat conduction system. After the heating structure transfers the heat to the top plate 310, the heat is evenly distributed to the thermal oil through the closely attached heat conducting coil 510, and then the heat is transferred to the bottom and side walls of the paint tank 100 by the thermal oil. The entire system ensures heat circulation distribution, avoids local overheating or cooling, and maintains a constant heating state of the paint.

[0038] This embodiment significantly improves the efficiency of thermal oil circulation and the uniformity of heat transfer by providing a thermal coil 510 and connecting it to the thermal oil chamber 200. The arrangement of the thermal coil 510 optimizes the heating area, effectively reduces heat loss, and improves the overall thermal efficiency of the equipment. The use of the circulation pump 530 further enhances the fluidity of the thermal oil, ensuring that the system remains stable under high power operating conditions, and avoiding the problem of reduced thermal efficiency or equipment loss caused by thermal oil retention.

[0039] Please continue to see Figure 3 As shown, according to another embodiment of the present invention, the side wall size of the outer wall 600 is larger than the side wall size of the heat-conducting structure 500, the side wall size of the heating structure is smaller than the side wall size of the outer wall 600, and a smoke exhaust port is provided on the outer wall 600 to form a smoke exhaust channel between the outer wall 600 and the heat-conducting structure 500 and the heating structure.

[0040] Specifically, the outer wall 600 is designed as a closed installation space, and its side wall size is larger than the side wall size of the heat-conducting structure 500 and the heating structure, forming a smoke exhaust channel for the flow of smoke. The smoke exhaust port is set at an appropriate position of the outer wall 600. When the smoke flows in the smoke exhaust channel, it contacts the surface of the heat-conducting structure 500, and transfers part of the heat to the heat-conducting structure 500, thereby achieving auxiliary heating of the heat-conducting structure 500. This secondary utilization method not only reduces the waste heat loss of the smoke, but also improves the overall thermal energy utilization efficiency of the system. At the same time, the orderly discharge of smoke in the channel prevents the high temperature or corrosion caused by smoke accumulation on the internal components of the equipment, thereby ensuring the stability of the equipment operation.

[0041] It should be noted that the smoke exhaust channel realizes the rapid exhaust of smoke, avoids its direct impact on the equipment, and improves the safety and operating environment of the equipment. In addition, the significant advantage of this embodiment is that the auxiliary heating of the heat-conducting structure 500 during the smoke exhaust process achieves the secondary utilization of thermal energy. Through this design, the system's demand for external heating energy is reduced, the overall energy utilization rate is improved, and the operating cost is reduced. At the same time, the design makes the temperature control of the equipment more efficient, further optimizes the uniformity of the coating heating and the heat transfer performance of the system.

[0042] Please continue to see Figure 1-3As shown, according to an optional embodiment of the present invention, the heat-conducting structure 500 also includes an anti-overflow structure 700, and the anti-overflow structure 700 is connected to the heat-conducting structure 500. The anti-overflow structure 700 is an important auxiliary part of the heat-conducting oil system, which is used to prevent the heat-conducting oil from overflowing due to temperature fluctuations or pressure changes during the circulation process. The anti-overflow structure 700 is connected to the heat-conducting structure 500, and can provide a temporary storage space when the heat-conducting oil is excessive, avoiding the loss and pollution caused by the overflow of the heat-conducting oil. At the same time, the anti-overflow structure 700 can also serve as a buffer device to adjust the pressure balance inside the system and reduce the liquid level fluctuation caused by the operation of the circulating pump 530 or thermal expansion. By being connected to the heat-conducting structure 500, the anti-overflow structure 700 ensures the safe flow of the heat-conducting oil and the stable operation of the system.

[0043] Specifically, by adding the anti-overflow structure 700, the problem of thermal oil overflowing due to pressure or temperature changes during operation is effectively avoided, reducing the risk of oil loss and equipment pollution. In addition, the buffering function of the anti-overflow structure 700 further improves the stability of system operation, ensures the balance of the liquid level and smooth flow of the thermal oil during the circulation process, and extends the service life of the equipment. This design also simplifies the replenishment and management of thermal oil and reduces the difficulty of system maintenance.

[0044] Please continue to see Figure 1-3 As shown, according to a further embodiment of the present invention, the overflow prevention structure 700 includes: an expansion oil pipe 710, which is connected to the thermal oil chamber 200; a high-level tank 720, which is connected to the expansion oil pipe 710, and a vent 721 is provided on the high-level tank 720, and the height of the high-level tank 720 is higher than the top of the thermal oil chamber 200. The expansion oil pipe 710, as the core channel of the overflow prevention structure 700, is connected to the thermal oil chamber 200 and is used to guide the flow of excess liquid generated by thermal expansion of the thermal oil. The high-level tank 720 is located above the thermal oil chamber 200, and its height is set higher than the top of the thermal oil chamber 200, so as to accommodate and store excess thermal oil generated by thermal expansion. The design of the vent 721 ensures that the pressure inside the high-level tank 720 is balanced with the outside world, avoiding oil overflow or leakage problems caused by pressure accumulation in the system. This structure not only realizes expansion compensation of the heat transfer oil through the combination of the expansion oil pipe 710 and the high-level tank 720, but also ensures the safety and stability of the entire heat transfer system.

[0045] Specifically, by providing the expansion oil pipe 710 and the high-level tank 720, the problem of liquid level fluctuation caused by thermal expansion of the heat transfer oil during operation is effectively solved, and the risk of heat transfer oil overflow and equipment pollution is avoided. The ventilation design of the high-level tank 720 further improves the system pressure regulation capability and ensures the stability and safety of equipment operation. In addition, this structure makes the replenishment and management of the heat transfer oil easier, reduces the maintenance cost of the system, and prolongs the service life of the equipment.

[0046] It is worth noting that the arrangement of the expansion oil pipe 710 can be optimized according to the equipment layout, for example, a spiral winding design can be used to save space or increase the heat transfer area. The material of the high-level tank 720 can be selected from transparent high-temperature resistant materials, such as high-temperature resistant glass or polyester resin, so as to visually observe the liquid level changes of the thermal oil. The vent 721 can be designed as a vent valve with a filter device to prevent external dust or foreign matter from entering the system. In addition, the position and size of the high-level tank 720 can be adjusted according to the expansion characteristics of the thermal oil to meet the design requirements of different systems. At the same time, an overflow protection device can be added to further improve safety and reliability.

[0047] Please continue to see Figure 1-3 As shown, in an optional manner of the present invention, the expansion oil pipe 710 is coiled around the side wall of the outer wall 600. The above structure not only increases the length and capacity of the expansion oil pipe 710, provides sufficient buffer space for the thermal expansion of the heat transfer oil, but also utilizes the heat dissipation performance of the outer wall 600 to further assist in controlling the temperature of the heat transfer oil. The coiling design of the expansion oil pipe 710 effectively utilizes the space of the outer wall 600, avoids the problem that other components in the system are limited due to insufficient installation space, and at the same time maintains the flow stability of the heat transfer oil in the pipeline, providing a good passage for the subsequent heat transfer oil flowing to the high-level tank 720.

[0048] Specifically, this embodiment optimizes the space utilization of the expansion oil pipe 710 and improves the structural compactness of the system by coiling the expansion oil pipe 710 around the side wall of the outer wall 600. In addition, this arrangement makes the expansion oil pipe 710 contact the outer wall 600, which helps to assist in heat dissipation and stabilize the temperature of the thermal oil, further improving the safety and efficiency of the system operation. The coiling design also increases the oil storage capacity of the pipeline, can better adapt to the thermal expansion characteristics of the thermal oil, reduce the risk of oil spills, and extend the continuity and stability of the equipment operation.

[0049] It should be noted that the winding method of the expansion oil pipe 710 can be adjusted according to the specific shape of the outer wall 600, for example, a spiral, serpentine or ring layout is adopted to further optimize space utilization and heat transfer effect.

[0050] Please continue to see Figure 1-3 As shown, in some examples of the present invention, an overflow pipe 800 is provided on the side wall of the high-level tank 720, and the other end of the overflow pipe 800 is vertically downward; and an oil receiving container 900 is provided below the high-level tank 720, and the opening of the oil receiving container 900 is directly opposite to the other end of the overflow pipe 800.

[0051] Specifically, the high-level tank 720 guides the excess thermal oil to the oil receiving container 900 through the overflow pipe 800, avoiding the oil overflow problem caused by the expansion of the thermal oil or the fluctuation of the liquid level. One end of the overflow pipe 800 is connected to the side wall of the high-level tank 720, and the other end is vertically downward to ensure that the thermal oil can flow smoothly into the oil receiving container 900. The oil receiving container 900 is located directly below the outlet of the overflow pipe 800, and its opening design is aligned with the outlet of the overflow pipe 800 to receive and temporarily store excess thermal oil to prevent the oil from leaking to the outside of the equipment or the working environment. This design ensures the safety of the system operation and simplifies the recovery and reuse of the thermal oil.

[0052] This embodiment completely solves the pollution and loss problems that may be caused by oil overflow from the high-level tank 720 by providing a combined structure of an overflow pipe 800 and an oil receiving container 900. The vertical design of the overflow pipe 800 makes the flow of the thermal oil smoother and avoids the safety hazards caused by pipeline blockage. The design of the oil receiving container 900 facilitates the collection and management of excess thermal oil, realizes the recycling of thermal oil, and reduces the operating cost of the system. In addition, the structure can also effectively prevent the adverse effects of thermal oil leakage on the equipment or the environment, and improve the stability and safety of equipment operation.

[0053] Please continue to see Figure 2 As shown, in some examples of the present invention, the heat-conducting structure 500 further includes a thermometer 540, which is used to detect the temperature of the heat-conducting oil. Through the temperature data obtained by the thermometer 540, the user can monitor the temperature change of the heat-conducting oil to ensure that it is always within the predetermined heating range, thereby avoiding the problem of heat-conducting oil degradation due to excessively high temperature or affecting the heating efficiency due to excessively low temperature.

[0054] This embodiment realizes real-time monitoring and control of the temperature of the heat transfer oil by providing a thermometer 540 in the heat transfer structure 500. The use of the thermometer 540 improves the safety of the equipment operation and avoids damage to the equipment and coating performance caused by abnormal temperature.
