[0021] like Figures 1 to 3 As shown, one embodiment of this application provides a heating device for a water tank 9 of a mixer truck, including a medium tank 2 for storing a heat exchange medium, a diesel heating component 4 fluidly connected to the medium tank 2 for heating the heat exchange medium and driving the flow of the heat exchange medium, and a heating pipe 1 fluidly connected to the medium tank 2 and the diesel heating component 4. The heating pipe 1 is used to adhere to the outer surface of the water tank 9, and the diesel heating component 4 is used to drive the heated heat exchange medium to flow through the heating pipe 1 across the outer surface of the water tank 9 to heat the water tank 9.

[0022] The heating device includes a medium tank 2, a diesel heating assembly 4, and a heating pipe 1. The medium tank 2 stores a heat exchange medium, preferably a refrigerant at -40°C, capable of operating in extremely cold weather (-40°C to -20°C) to ensure the normal operation of the diesel heating assembly 4. The diesel heating assembly 4, including a water pump, oil pump, ignition coil, and combustion chamber, heats the heat exchange medium in the medium tank 2 and drives its flow. The heating pipe 1 is a bendable copper pipe, with both ends connected to the medium tank 2 and the diesel heating assembly 4, respectively. It can be U-shaped and fitted to the outer surface of the water tank 9 according to its size, allowing for greater contact between the heating pipe 1 and the water tank 9, thus improving heating efficiency. The medium tank 2 is connected to the diesel heating assembly 4 via an inlet pipe 3. The diesel heating assembly 4 drives the heat exchange medium to flow through the heating pipe 1, where it exchanges heat with the water inside the water tank 9, thereby heating the water tank and maintaining its temperature. In a further embodiment, in order to adapt to use in different climate regions, the number of diesel heating components 4 can be increased or diesel heating components 4 with different power can be selected to increase the applicability and competitiveness of the mixer truck.

[0023] The heating device further comprises a temperature sensing device for sensing the temperature of the heat exchange medium, which is arranged in the medium tank 2 and is in communication connection with the diesel heating assembly 4, and when the temperature sensing device senses that the temperature of the heat exchange medium exceeds a preset high temperature threshold, a signal is sent to the diesel heating assembly 4, and the diesel heating assembly 4 stops heating the heat exchange medium. In a further embodiment, the preset temperature range of the temperature sensing device is 50-80℃.

[0024] The heating device further comprises a water inlet pipe 3, a water return pipe 6 and a heat insulation structure. The water inlet pipe 3 connects the medium tank 2 with the heating pipe 1, and the water return pipe 6 connects the other end of the heating pipe 1 with the medium tank 2, so that after the heat exchange medium is heated by the diesel heating assembly 4, it enters the heating pipe 1 to exchange heat with the water tank 9, and finally returns to the medium tank 2, and the process is repeated, so as to heat the liquid water in the water tank 9. The heat insulation structure comprises self-adhesive heat insulation cotton 7, which is used to wrap and fix the bendable heating pipe 1 and prevent heat in the heating pipe 1 from being dissipated to the atmosphere, thereby improving the heating efficiency and stability of the heating device.

At the same time, the heat exchange medium uses cooling liquid that can adapt to -40℃, which ensures that the heating device can cope with extremely cold weather of -40℃ to -20℃, and meets the needs of the concrete construction site. In addition, the diesel heating assembly can select different power assemblies or set multiple assemblies according to regional conditions, so as to quickly achieve the purpose of heating and increase the applicability and competitiveness of the mixing truck.

The diesel heating assembly (4) rapidly heats the heat exchange medium in the medium tank (2) to 70°C-80°C, and continuously delivers the heat exchange medium into the heating pipe (1). The heat exchange medium is cooled after heat exchange with the inside of the water tank (9) in the heating pipe (1), and is returned to the medium tank (2) through the water return pipe (6). The process is repeated to heat the water tank (9) and maintain the water temperature.

[0028] According to calculation, if the heating device provided by the embodiment is used to heat 1000L water to increase the temperature by 20°C-25°C in 1 hour, the heating power needs to be 36KW according to 80% heat efficiency, so as to achieve the core purpose of the scheme. Therefore, the diesel heating assembly (4) with corresponding power can be selected according to the actual conditions of the construction site to meet the needs of concrete construction.

The heating device is used for heating water in the water tank (9). The diesel heating assembly (4) of the heating device adopts electronic ignition, and the ignition coil of the diesel heating assembly (4) is connected to the storage battery of the mixer truck. This ignition mode can eliminate external interference and ensure power stability of the diesel heating assembly (4), so that the heating efficiency of the heating device is not affected by the driving state of the mixer truck, and the purpose of heating the water tank is achieved in a short time. In addition, the diesel heating assembly (4) with required power can be selected according to the actual conditions of the construction site, so that the water tank (9) can be rapidly heated in extremely cold weather conditions.
