[0028] Example 1

[0029] This embodiment proposes a domestic hot water heat recovery device, such as Figure 1As shown, the collecting box 1 includes a collection box 1, which is fixed with a pipe at the bottom, and a dirt removal component is provided on the pipe. The dirt removal component includes a filter 2 and a dirt remover 3. The filter 2 and the dirt remover 3 are both provided on the pipe at the bottom of the collecting box 1. The domestic hot wastewater is coarsely filtered by the filter 2, and then the domestic hot wastewater is finely filtered by the dirt remover 3 to avoid impurities in the domestic hot wastewater and to prevent the impurities from adhering to the inside of the pipe.

[0030] like Figure 1 As shown, the heat recovery component includes a stainless steel heat sink 4, a hot-dip galvanized pipe 5, a solenoid valve 6, and a temperature sensor 7. The side of the stainless steel heat sink 4 is connected to the pipe at the bottom of the collection box 1. The collection box 1 collects domestic hot wastewater. The domestic wastewater flows out of the collection box 1, passes through the filter 2 and the decontaminant remover 3, and finally enters the interior of the stainless steel heat sink 4. The heat is dissipated into the room through the stainless steel heat sink 4, providing heating for people's daily life in winter.

[0031] A temperature sensor 7 is fixedly installed inside the stainless steel heat sink 4, a hot-dip galvanized pipe 5 is fixedly installed on the bottom of the stainless steel heat sink 4, and a solenoid valve 6 is fixedly installed on the hot-dip galvanized pipe 5. The temperature sensor 7 is electrically connected to the solenoid valve 6, and the solenoid valve 6 is electrically connected to the controller through a signal transmission line, and the controller is electrically connected to the temperature sensor 7.

[0032] The temperature of the domestic hot wastewater inside the stainless steel heat sink 4 is monitored by temperature sensor 7. When the temperature of the domestic hot wastewater inside the stainless steel heat sink 4 falls below a set value, the temperature sensor 7 transmits a signal to the controller, which opens the solenoid valve 6 to discharge the low-temperature domestic hot wastewater. At the same time, the electric check valve opens to re-supply hot water into the stainless steel heat sink 4, ensuring uninterrupted heating.

[0033] In this embodiment, domestic hot wastewater is collected by a collection box 1, and the domestic hot wastewater inside the collection box 1 is introduced into the stainless steel heat dissipation box 4. The stainless steel heat dissipation box 4 is used to dissipate the heat of the domestic hot wastewater into the room for heating. When the temperature of the domestic hot wastewater inside the stainless steel heat dissipation box 4 is lower than the set value, the water inside the stainless steel heat dissipation box 4 is first completely drained, and then the domestic hot wastewater inside the collection box 1 is added to the stainless steel heat dissipation box 4 to avoid heating interruption.

[0034] Example 2

[0035] Based on Example 1, this example proposes a domestic hot water heat recovery device, such as Figure 2 and 3As shown, the filter element 2 includes a hot-dip galvanized steel pipe 21, a sealing cylinder 22, a circular filter screen 23, a return spring 24 and a push rod 25. The inner wall of the hot-dip galvanized steel pipe 21 is slidingly connected to the sealing cylinder 22, the hot-dip galvanized steel pipe 21 is fixedly connected to the pipeline, the middle part of the inner wall of the sealing cylinder 22 is rotatably connected to the circular filter screen 23, and the top of the sealing cylinder 22 is fixedly installed with a return spring 24 installed on the inner wall of the hot-dip galvanized steel pipe 21. The push rod 25 is fixedly installed on the inner wall of the hot-dip galvanized steel pipe 21 and directly below the circular filter screen 23. The push rod 25 is located on the moving path of the circular filter screen 23.

[0036] A torque spring 27 is elastically connected to the rotational connection between the blocking cylinder 22 and the circular filter screen 23 , and the blocking cylinder 22 completely covers the inlet of the dirt remover 3 .

[0037] After impurities accumulate on the circular filter 23, the water flow rate of the circular filter 23 decreases, and the circular filter 23 and the blocking cylinder 22 are washed underwater. The blocking cylinder 22 moves, causing the return spring 24 to deform. When the blocking cylinder 22 moves to the water inlet of the dirt remover 3, the blocking cylinder 22 blocks the water inlet of the dirt remover 3, preventing impurities on the circular filter 23 from entering the dirt remover 3. At this time, the circular filter 23 is lifted and rotated by the push rod 25. The rotation of the circular filter 23 compresses the torque spring 27, and the circular filter 23 tilts. The falling water inside the collection box 1 washes off the impurities on the circular filter 23, and then the water flow rate of the circular filter 23 is restored. The circular filter 23 and the blocking cylinder 22 are reset under the action of the return spring 24, and then the torque spring 27 returns the circular filter 23 to its initial state.

[0038] The push rod 25 adopts an L-shaped structure, and the vertical portion of the push rod 25 is misaligned with the blocking tube 22. This prevents the push rod 25 from hindering the movement of the blocking tube 22.

[0039] like Figure 4 As shown, the circular filter screen 23 is in an inclined state, and a pad is fixedly installed on the inner wall of the sealing cylinder 22 and below the circular filter screen 23. The circular filter screen 23 is divided into two parts, left and right, along the axis of the torque spring 27. The area of ​​the right part of the circular filter screen 23 is larger than that of the left part. Therefore, when the circular filter screen 23 is impacted by water, the force on the right part of the circular filter screen 23 is greater than that on the left part. Therefore, when the water impacts the circular filter screen 23, the right part thereof deflects downward. However, since the pad limits the circular filter screen 23, the circular filter screen 23 will not be directly opened by the water impact.

[0040] The bottom of the sealing cylinder 22 is fixedly connected to a sealing plug 26 via a straight rod. The top of the sealing plug 26 adopts a truncated cone structure. The bottom of the hot-dip galvanized steel pipe 21 is fixedly mounted with a sewage tank 8. During normal water flow, the sealing plug 26 blocks the sewage tank 8, and water enters from the water inlet of the sludge separator 3. When flushing the circular filter 23, the sealing cylinder 22 blocks the water inlet of the sludge separator 3, and the sealing plug 26 opens the sewage tank 8, directing impurities intercepted by the filter element 2 into the sewage tank 8.

[0041] In this embodiment, the circular filter 23 is blocked and subjected to a strong impact force from the water. The circular filter 23 and the blocking cylinder 22 are washed underwater by the water. The blocking cylinder 22 moves, causing the return spring 24 to deform. When the blocking cylinder 22 moves to the water inlet of the dirt remover 3, the blocking cylinder 22 blocks the water inlet of the dirt remover 3, preventing impurities on the circular filter 23 from entering the dirt remover 3. At this time, the circular filter 23 is lifted and rotated by the push rod 25. The rotation of the circular filter 23 compresses the torque spring 27, causing the circular filter 23 to tilt, and the falling water inside the collection box 1 washes away the impurities on the circular filter 23.

[0042] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
