Description

Technical Field

[0001] This utility model belongs to the technical field of energy recovery devices, specifically relating to a heat source energy recovery device. Background Technology

[0002] In daily life and industrial production, hot water becomes wastewater after use, carrying away a large amount of heat energy and being discharged into the sewer system. To save energy, it is necessary to recover and reuse the heat energy from this wastewater to save heating energy for boilers and water heaters.

[0003] Existing technologies, during recycling, control the inflow directions of hot and cold water to quickly transfer heat from wastewater to cold water. However, due to the rapid flow of hot water, the contact time between hot water and cold water pipes is short, and the poor thermal conductivity of cold water pipes results in a large amount of heat dissipating into the cold water, leading to low water temperature. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat source energy recovery device. This heat source energy recovery device aims to solve the technical problems of low water temperature caused by the rapid flow rate of hot water, short contact time between hot water and cold water pipes, poor heat conduction of cold water pipes, and the dissipation of heat from wastewater into a large amount of cold water.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a heat source energy recovery device, which includes an energy recovery box and hot water inlet pipe and hot water outlet pipe installed at both ends of the energy recovery box. Both ends of the energy recovery box are rotatably clamped with fastening pipes, and sealing plates are detachably installed on the side wall of the energy recovery box. A heat absorption circulation pipe is embedded in the energy recovery box, and both ends of the heat absorption circulation pipe are threaded into the two fastening pipes respectively. Multiple heat-conducting copper plates are embedded and fixed at the center of the heat absorption circulation pipe.

[0008] When using this technical solution, a hot water inlet pipe and a hot water outlet pipe are respectively installed at both ends of the energy recovery box. The hot water inlet pipe is located at the bottom of the energy recovery box. After the hot water inlet pipe at the bottom fully fills the energy recovery box with water, it is discharged from the hot water outlet pipe. The hot water is stored in the energy recovery box, so that the heat absorption circulation pipe is always in contact with hot water. At the same time, the coiled heat absorption circulation pipe increases the contact time with hot water. A heat-conducting copper plate is embedded and fixed in the heat absorption circulation pipe. After absorbing heat, the heat-conducting copper plate can heat the cold water inside the heat absorption circulation pipe. The heat-conducting copper plate and the heat absorption plate installed on it improve the heat absorption efficiency. Fastening pipes are rotated and clamped at both ends of the energy recovery box. The cold water inlet pipe and cold water outlet pipe at both ends of the fastening pipe are unscrewed, and the fastening pipe is rotated to bend the heat absorption circulation pipe and separate it. After unscrewing the fastening bolts and removing the sealing plate, the heat absorption circulation pipe can be taken out of the energy recovery box, which improves the convenience of pipe disassembly and replacement.

[0009] Preferably, the energy recovery box is provided with a cold water inlet pipe and a cold water outlet pipe at both ends, and the cold water inlet pipe and the cold water outlet pipe are respectively threaded into two fastening pipes.

[0010] Furthermore, the two fastening pipes are respectively sealed to the energy recovery box, the cold water inlet pipe, and the cold water outlet pipe, and a thermometer is installed at the top of the cold water outlet pipe.

[0011] Furthermore, damping grooves are equally spaced at both ends of the heat-conducting copper plate, and heat-absorbing plates are tightly inserted between multiple damping grooves on the same side.

[0012] Furthermore, a positioning plate is embedded in the side wall of the energy recovery box, and a rubber sealing plate is embedded in the positioning plate.

[0013] Furthermore, the rubber sealing plate has multiple grooves, and the side wall of the positioning plate has screw holes corresponding to the grooves.

[0014] Furthermore, the sidewalls of the sealing plate are fitted with fastening bolts in a rectangular array, and the fastening bolts are threaded through grooves and inserted into screw holes.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model has a hot water inlet pipe and a hot water outlet pipe installed at both ends of the energy recovery box. The hot water inlet pipe is located at the bottom of the energy recovery box. After the hot water inlet pipe at the bottom is fully filled with water, it is discharged from the hot water outlet pipe. The hot water is stored in the energy recovery box, so that the heat absorption circulation pipe is always in contact with the hot water. At the same time, the coiled heat absorption circulation pipe increases the contact time with the hot water.

[0018] By embedding a heat-conducting copper plate inside the heat-absorbing circulation pipe, the copper plate can heat the cold water inside the pipe after absorbing heat. The copper plate and the heat-absorbing plate installed on it improve the heat absorption efficiency. By rotating and clamping fastening pipes at both ends of the energy recovery box, the cold water inlet and outlet pipes at both ends of the fastening pipes can be unscrewed, and the fastening pipes can be rotated to bend the heat-absorbing circulation pipe and separate it. After unscrewing the fastening bolts and removing the sealing plate, the heat-absorbing circulation pipe can be taken out of the energy recovery box, which improves the convenience of pipe disassembly and replacement.

[0026] This specific embodiment is a heat source energy recovery device, the structural schematic diagram of which is shown below. Figure 1 and Figure 2 As shown, the heat source energy recovery device includes an energy recovery box 1 and hot water inlet pipe 6 and hot water outlet pipe 2 installed at both ends of the energy recovery box 1. Both ends of the energy recovery box 1 are rotatably clamped with fastening pipes 12, and sealing plates 4 are detachably installed on the side wall of the energy recovery box 1. A heat absorption circulation pipe 9 is embedded in the energy recovery box 1. Both ends of the heat absorption circulation pipe 9 are threaded into the two fastening pipes 12, and multiple heat-conducting copper plates 11 are embedded and fixed at the center of the heat absorption circulation pipe 9.

[0027] The energy recovery box 1 is equipped with a cold water inlet pipe 3 and a cold water outlet pipe 7 at both ends. The cold water inlet pipe 3 and the cold water outlet pipe 7 are threaded into two fastening pipes 12. The two fastening pipes 12 are sealed to the energy recovery box 1, the cold water inlet pipe 3 and the cold water outlet pipe 7 respectively. A thermometer 8 is installed at the top of the cold water outlet pipe 7. Damping grooves 13 are equally spaced at both ends of the heat-conducting copper plate 11. Heat-absorbing plates 10 are tightly inserted between multiple damping grooves 13 on the same side. The hot water inlet pipe 6 is located at the bottom of the energy recovery box 1. The hot water inlet pipe 6 at the bottom fills the energy recovery box 1 with water and then discharges it from the hot water outlet pipe 2. The hot water is stored in the energy recovery box 1, so that the heat-absorbing circulation pipe 9 is always in contact with the hot water. At the same time, the coiled heat-absorbing circulation pipe 9 increases the contact time with the hot water.

[0028] A positioning plate 14 is embedded in the side wall of the energy recovery box 1. A rubber sealing plate 16 is embedded in the positioning plate 14. Multiple grooves 15 are provided on the rubber sealing plate 16. The side wall of the positioning plate 14 is provided with screw holes 17 corresponding to the grooves 15. Fastening bolts 5 are installed in a rectangular array on the side wall of the sealing plate 4. The fastening bolts 5 pass through the grooves 15 and are threaded into the screw holes 17. After absorbing heat, the heat-conducting copper plate 11 can heat the cold water inside the heat absorption circulation pipe 9. The heat-conducting copper plate 11 and the heat absorption plate 10 installed on it improve the heat absorption efficiency. By rotating and clamping the fastening pipes 12 at both ends of the energy recovery box 1, the cold water inlet pipe 3 and the cold water outlet pipe 7 at both ends of the fastening pipe 12 are unscrewed. The fastening pipe 12 is rotated to bend the heat absorption circulation pipe 9 and separate it from the fastening pipe. After unscrewing the fastening bolts 5 and removing the sealing plate 4, the heat absorption circulation pipe 9 is taken out of the energy recovery box 1.

[0029] Working principle: When using the device of this technical solution, the hot water inlet pipe 6 is located at the bottom of the energy recovery box 1. The hot water inlet pipe 6 at the bottom fills the energy recovery box 1 with water and then discharges it from the hot water outlet pipe 2. The hot water is stored in the energy recovery box 1, so that the heat absorption circulation pipe 9 is always in contact with the hot water. At the same time, the coiled heat absorption circulation pipe 9 increases the contact time with the hot water. After absorbing heat, the heat-conducting copper plate 11 can heat the cold water inside the heat absorption circulation pipe 9. The heat-conducting copper plate 11 and the heat absorption plate 10 installed on it improve the heat absorption efficiency. When disassembling the pipe in the energy recovery box 1, after unscrewing the fastening bolt 5 and removing the sealing plate 4, unscrew the cold water inlet pipe 3 and cold water outlet pipe 7 at both ends of the fastening pipe 12, and rotate the fastening pipe 12 to bend the heat absorption circulation pipe 9 and separate it. The heat absorption circulation pipe 9 can then be taken out of the energy recovery box 1, which improves the convenience of pipe disassembly and replacement.
