[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figure 1-Figure 4 As shown, the utility model is a device for recovering residual heat from melting aluminum ingots, comprising

[0030] The fixing mechanism 1 is used to fix the device and maintain the stability of operation;

[0031] The inner frame mechanism 2 acts on the water circulation process to heat the water;

[0032] An inner frame mechanism 2 is fixedly inserted into the inner surface wall of the fixing mechanism 1;

[0033] The inner frame mechanism 2 includes an isolation box 201, and a plurality of partitions 205 are fixedly inserted into the inner wall of the isolation box 201, and the plurality of partitions 205 form an annular circulation channel inside the isolation box 201. A group of temperature detectors 202 are fixedly inserted into the inner wall of the isolation box 201. One side of the outer wall of the isolation box 201 is fixedly connected to a switch valve A203, and the output end of the switch valve A203 is fixedly connected to an output pipe 204. The other side of the outer wall of the isolation box 201 is fixedly connected to a switch valve B206, and the input end of the switch valve B206 is fixedly connected to an input pipe 207.

[0034] The effect achieved by the entire embodiment 1 is that, first, a ring-shaped circulation channel is formed inside the isolation box 201 through multiple partitions 205, and then when the switch valve B206 is in the open state, the external low-temperature liquid can be transferred to the interior of the isolation box 201 through the input pipe 207, and then the liquid in the low-temperature state is kept filling the interior of the isolation box 201, and finally the gas with residual heat enters the interior of the chamber through the input end of the external pipe 103.

[0035] Example 2, as Figure 2-Figure 4 As shown, the fixing mechanism 1 includes an installation outer frame 101, a fixing seat 102 is fixedly installed on the top of the installation outer frame 101, an external tube 103 is fixedly inserted inside the fixing seat 102, and the output end of the external tube 103 is fixedly connected to an internal circulation tube 104, a group of anti-slip pads 105 are fixedly installed on the bottom of the installation outer frame 101, one side of the outer wall of the internal circulation tube 104 is fixedly connected to a solenoid valve 106, and the output end of the solenoid valve 106 is fixedly connected to a discharge pipe 107, the outer wall of the isolation box 201 is fixedly inserted inside the installation outer frame 101, and the outer walls of the internal circulation tube 104 are fixedly inserted inside the isolation box 201 and a group of partitions 205.

[0036] The effect achieved by the entire embodiment 2 is that the waste heat can be transferred to the inside of the internal circulation pipe 104 through the external pipe 103, and then the heat can be transferred to the water with lower temperature through the outer wall of the internal circulation pipe 104, thereby achieving effective heating treatment of the water. When the water is heated to a certain degree and the temperature reaches a certain value, the water temperature can be detected by the temperature detector 202 and transferred to the inside of the external control system, and then the switch valve A203 is kept in the open state to discharge the heated liquid and achieve water replacement treatment.

[0037] Working principle: First, a ring-shaped circulation channel is cleverly constructed inside the isolation box 201 using multiple partitions 205. Then, when the switch valve B206 is activated to the open state, the external low-temperature treated liquid smoothly enters the isolation box 201 through the input pipe 207, ensuring that the box is filled with low-temperature liquid. Then, the gas containing residual heat enters its interior through the input end of the external pipe 103. In this process, the external pipe 103 acts as a bridge for heat transfer, introducing the residual heat into the inner circulation pipe 104. In the inner circulation pipe 104, the heat is effectively transferred to the surrounding water with lower temperature through its outer wall, realizing the water heating process. As the water temperature gradually rises to the preset temperature threshold, the temperature detector 202 accurately captures this change and transmits the water temperature information to the external control system. At this time, the control system responds to the instruction to open the switch valve A203, allowing the heated liquid to be discharged from the isolation box 201, and at the same time making room for the entry of a new batch of low-temperature liquid, thereby realizing the replacement of heated water and ensuring the continuous and efficient operation of the system.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
