Description

Technical Field

[0001] This utility model relates to the field of heat energy recovery and utilization technology, and in particular to a heat energy recovery and utilization device for a heat exchanger used in the production of gold substitutes. Background Technology

[0002] Gold substitutes are a class of functional materials that use copper alloys as the core substrate (such as copper-zinc alloys, copper-nickel-zinc alloys, etc.) or simulate the color and appearance of the precious metal gold through surface treatment technologies (such as chemical plating, vacuum coating), and have a significantly lower cost than pure gold. They are widely used in jewelry manufacturing, electronic component plating, craft decoration, anti-counterfeiting labels and other fields.

[0003] However, the alloy melt after gold smelting and the reaction liquid after chemical plating are both at extremely high temperatures. They need to be cooled down by heat exchangers before the next process can proceed. Traditional heat exchangers rely on tubes for heat transfer. The medium flows slowly in the tubes and is prone to stagnation, so the heat cannot be dissipated sufficiently. Sometimes, the medium is still hot to the touch after cooling, so it can only be discharged directly. Not only is the heat wasted, but the cooling pump and cooling water also need to be turned on to cool it down. This wastes the heat that could have been reused and incurs additional electricity and water bills. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat energy recovery and utilization device for a heat exchanger used in the production of substitute gold. This solves the problem that the alloy melt after smelting substitute gold and the reaction liquid after chemical plating are at high temperatures and need to be cooled by a heat exchanger before entering subsequent processes. However, traditional bare tube heat exchangers are prone to stagnation due to the low flow velocity of the medium inside the tubes, resulting in insufficient heat dissipation. The cooled medium still maintains a high temperature and can only be directly discharged, which not only wastes waste heat but also requires the additional startup of a cooling pump to run cooling water for secondary cooling, increasing water and electricity costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat energy recovery and utilization device for a heat exchanger used in the production of gold substitutes includes a heat exchanger body. A bracket is symmetrically fixedly installed at the lower end of the heat exchanger body. A low-temperature medium inlet pipe and a low-temperature medium outlet pipe are symmetrically installed at the upper end of the heat exchanger body. A high-temperature medium inlet pipe and a high-temperature medium outlet pipe are symmetrically installed on the side wall of the heat exchanger body. An electronic valve is installed on the high-temperature medium outlet pipe. An inner groove is formed on the side wall of the high-temperature medium outlet pipe, and a sealing ring is inserted into the inner groove. A filter screen is fixedly installed inside the sealing ring. A heat energy recovery structure is installed at the end of the high-temperature medium outlet pipe away from the heat exchanger body. The heat energy recovery structure includes a heat exchange cylinder, which is fixedly connected to the high-temperature medium outlet pipe. A drain pipe is installed at the end of the heat exchange cylinder away from the high-temperature medium outlet pipe. A bracket provides stable support. The high and low temperature medium pipes form a heat exchange cycle. The electronic valve controls the flow rate of the high-temperature medium. The sealing ring and filter screen prevent leakage and clogging. The outlet pipe connects to the heat energy recovery structure, realizing the integration of heat exchange and waste heat utilization.

[0007] Preferably, a first sealing ring is symmetrically fixedly installed on the heat exchange cylinder, and heat dissipation fins are arrayed on the heat exchange cylinder. The heat exchange cylinder provides a space for the release of residual heat for the high-temperature medium, and the drain pipe discharges the medium after the release of residual heat in an orderly manner to avoid stagnation that affects efficiency.

[0008] Preferably, both ends of the heat exchange cylinder are threaded with threaded rings, and water pipes are installed on both threaded rings. A cylinder body is installed between the two threaded rings. Spring pieces are symmetrically and equidistantly fixed in the inner wall of the cylinder. Annular grooves are opened on the opposite ends of the two threaded rings. The threaded rings are detachable for easy maintenance, and the water pipes form a closed-loop water circulation. The cylinder body forms a closed water circulation space, the spring pieces provide a deformation basis for sealing, and the annular grooves are adapted to the first sealing ring to improve sealing stability.

[0009] Preferably, a second sealing ring is fixedly installed on each of the two threaded rings at their opposite ends, and a turbulence generator is fixedly installed inside the heat exchange cylinder. The second sealing ring and the spring plate cooperate to form an adaptive seal to prevent medium crossflow and leakage. The turbulence generator forces the medium to turbulent flow, improves the heat transfer coefficient, and ensures that heat is fully released.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Through a synergistic design of enhanced heat transfer, reliable sealing, and recycling, efficient and stable recovery of waste heat from the high-temperature medium in the production of substitute gold is achieved. On the one hand, the turbulence generator inside the heat exchange cylinder forces the high-temperature medium to generate turbulence, which, combined with the array-type heat dissipation fins, double-enhances the waste heat extraction efficiency, increasing the high-temperature medium waste heat recovery rate to over 75%, significantly reducing heat waste in processes such as substitute gold smelting and reaction. On the other hand, by using a threaded ring assembly to drive the deformation of the spring sheet to compress the second sealing ring, an adaptive sealing structure is formed, effectively preventing high-temperature medium leakage and cross-flow in the water circulation system. Combined with the closed-loop water circulation design of the water pipe, the recovered waste heat can be directed for auxiliary processes in substitute gold production such as raw material preheating and cleaning water heating, directly reducing production energy consumption costs by 30%-40%, while ensuring the continuous stability of the waste heat recovery process, adapting to the needs of large-scale substitute gold production.

[0020] This application provides a heat energy recovery and utilization device for a heat exchanger used in the production of substitute gold. It effectively solves the problem that the alloy melt after smelting substitute gold and the reaction liquid after chemical plating are at high temperatures and need to be cooled by a heat exchanger before entering subsequent processes. However, traditional bare tube heat exchangers are prone to stagnation due to the low flow velocity of the medium inside the tube, resulting in insufficient heat dissipation. The medium remains at a high temperature after cooling and can only be discharged directly, which not only wastes waste heat but also requires the additional startup of a cooling pump to run cooling water for secondary cooling, increasing water and electricity costs. This equipment achieves efficient and stable recovery of waste heat from the high-temperature medium in the production of substitute gold through the synergistic design of enhanced heat transfer, reliable sealing, and circulation recovery. The recovery rate exceeds 75%, which can utilize waste heat in a targeted manner, reduce energy consumption by 30%-40%, and prevent leakage and crossflow, making it suitable for large-scale production.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application effectively solves the problem that the alloy melt after gold substitute smelting and the reaction liquid after electroless plating are at high temperatures and need to be cooled by a heat exchanger before entering subsequent processes. However, traditional bare tube heat exchangers suffer from insufficient heat dissipation due to the low flow velocity of the medium inside the tubes, which easily leads to stagnation. The cooled medium still maintains a high temperature and can only be directly discharged, resulting in waste of waste heat and requiring an additional cooling pump to run cooling water for secondary cooling, increasing water and electricity costs. The overall idea is as follows: A heat energy recovery and utilization device for a heat exchanger used in gold substitute production, including a heat exchanger... The heat exchanger body 1 has a bracket 2 symmetrically fixedly installed at the lower end of the heat exchanger body 1. A low-temperature medium inlet pipe 3 and a low-temperature medium outlet pipe 4 are symmetrically installed at the upper end of the heat exchanger body 1. A high-temperature medium inlet pipe 5 and a high-temperature medium outlet pipe 6 are symmetrically installed on the side wall of the heat exchanger body 1. An electronic valve 7 is installed on the high-temperature medium outlet pipe 6. An inner groove 8 is opened on the side wall of the high-temperature medium outlet pipe 6. A sealing ring 9 is inserted into the inner groove 8. A filter screen 10 is fixedly installed inside the sealing ring 9. A heat recovery structure is installed at the end of the high-temperature medium outlet pipe 6 away from the heat exchanger body 1.

[0023] The heat recovery structure includes a heat exchange cylinder 11, which is fixedly connected to a high-temperature medium outlet pipe 6. A drain pipe 14 is installed on the end of the heat exchange cylinder 11 away from the high-temperature medium outlet pipe 6.

[0024] A first sealing ring 12 is symmetrically fixedly installed on the heat exchange cylinder 11, and heat dissipation fins 13 are arrayed on the heat exchange cylinder 11.

[0025] Both ends of the heat exchange cylinder 11 are threaded with threaded rings 15, and water pipes 16 are installed on both threaded rings 15.

[0026] A cylinder 17 is installed between two threaded rings 15. Spring pieces 18 are symmetrically and equidistantly fixed in the inner wall of the cylinder 17. Annular grooves 19 are opened on the opposite ends of the two threaded rings 15.

[0027] A second sealing ring 20 is fixedly installed on each of the two threaded rings 15 at their opposite ends, and a turbulence generator 21 is fixedly installed inside the heat exchange cylinder 11.

[0028] To address the problems existing in the prior art, this utility model provides a heat energy recovery and utilization device for a heat exchanger used in the production of substitute gold. This device achieves efficient and stable recovery of waste heat from the high-temperature medium in the production of substitute gold through the synergistic design of enhanced heat transfer, reliable sealing and circulation recovery, with a recovery rate of over 75%. It can utilize waste heat in a targeted manner, reduce energy consumption by 30%-40%, and also prevent leakage and crossflow, making it suitable for large-scale production.

[0029] Working principle:

[0030] In the first step, during use, the low-temperature medium enters and exits through the low-temperature medium inlet pipe 3 and the low-temperature medium outlet pipe 4, circulating inside the heat exchanger body 1. The gold substitute raw material enters and exits through the high-temperature medium inlet pipe 5 and the high-temperature medium outlet pipe 6, circulating inside the heat exchanger body 1 for heat exchange. After heat exchange, the high-temperature medium flows into the heat exchange cylinder 11 through the high-temperature medium outlet pipe 6, and then dissipates heat in the heat exchange cylinder 11. The turbulence generator 21 inside the heat exchange cylinder 11 can force the fluid to generate turbulence, increasing the heat transfer coefficient by 30%-50% and preventing the fluid from stagnating in the pipe, which would prevent heat from being released. The heat is transferred through the heat exchange cylinder 11 to the heat dissipation fins 13. The heat dissipation fins 13 are 10-20mm high and 5-10mm apart. This structure can increase the heat exchange area by 2-5 times. This equipment can quickly release the waste heat of the gold substitute raw material, shorten the heat exchange cycle, and greatly enhance the extraction capacity of the waste heat of the high-temperature medium.

[0031] The second step involves placing the cylinder 17 on the heat exchange cylinder 11, then threaded rings 15 are installed at both ends of the heat exchange cylinder 11. As the two threaded rings 15 rotate, the two first sealing rings 12 will be inserted into the two annular grooves 19 respectively. At the same time, the two second sealing rings 20 will also be inserted into the spring 18. At this time, the spring 18 will be slightly deformed after being subjected to the compressive force, which will then press the second sealing rings 20 in the opposite direction to make them fit tightly against the inner wall of the cylinder 17, thus achieving a seal. Then, water can be injected and discharged from the water pipe 16 to form a circulation, and the heat of the substitute gold raw material will be absorbed and utilized by the water.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
