DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-4The utility model provides a technical solution: a sewage heat recovery treatment device, comprising: a bottom plate 1, a controller 2 is connected to the left side of the upper surface of the bottom plate 1, a heating chamber 3 is connected to the right side of the upper surface of the bottom plate 1 and located at the right end of the controller 2, a water inlet pipe 4 is connected to the left side of the heating chamber 3, the left side of the water inlet pipe 4 is connected to the tap water pipe, a water outlet 5 is connected to the lower side of the heating chamber 3, the right side of the water outlet 5 extends to the right side of the lower end bracket of the heating chamber 3, the water outlet 5 is connected to the tap water pipe, a sewage chamber 6 is connected to the front end of the upper surface of the bottom plate 1, a sewage inlet 7 is connected to the inside of the upper left side of the sewage chamber 6, a sewage outlet 8 is connected to the upper right side of the sewage chamber 6, and the right side of the upper surface of the bottom plate 1 is connected to the sewage outlet 8. The end of the bottom plate 1 is connected to a compressor 9 at the lower end of the sewage chamber 6, and the heating chamber 3 and the sewage chamber 6 are both connected with a heat-conducting coil 10, and the heating coil 10 in the heating chamber 3 is connected to the output end of the compressor 9. A capillary 11 is provided on the left side of the upper end of the bottom plate 1 and on the left side of the compressor 9, and the heating coil 10 in the heating chamber 3 is communicated with the capillary 11, and the other end of the capillary 11 is communicated with the left side of the heat-conducting coil 10 in the sewage chamber 6, and the right side of the heat-conducting coil 10 in the sewage chamber 6 is connected to the input port of the compressor 9, and the heating chamber 3 and the sewage chamber 6 are both connected with a temperature detector, and the controller 2 is electrically connected to the temperature detector and the compressor 9, and the heat-conducting coil 10 is filled with refrigerant.
[0024] When in use, the water inlet pipe 4 is connected to the tap water pipe, the water outlet 5 is connected to the water pipe, the sewage inlet 7 is connected to the sewage discharge pipe, the sewage discharge port 8 is connected to the sewage pipe, and the compressor 9 is started. The compressor 9 will extract and pressurize the refrigerant inside the heat-conducting coil 10, and then discharge it through the output end of the compressor 9. At this time, the refrigerant is a high-temperature and high-pressure gas. At this time, it enters the inside of the heat-conducting coil 10 inside the heating chamber 3. The heat-conducting coil 10 inside the heating chamber 3 contacts the tap water with a lower temperature inside the heating chamber 3. At this time, the refrigerant is cold. The gas condenses into liquid and releases heat, thereby heating the tap water inside the heating chamber 3. The refrigerant then enters the capillary 11, and after passing through the capillary 11, enters the heat transfer coil 10 inside the sewage chamber 6, and becomes a low-temperature and low-pressure liquid. There is sewage with a higher temperature inside the sewage chamber 6. The refrigerant then evaporates again into a higher-temperature gas. The higher-temperature refrigerant gas is then pumped into the compressor 9, becoming a high-temperature and high-pressure gas, and enters the heating coil 10 inside the heating chamber 3, and so on.
[0025] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a safety valve 21 is connected to the right side of the upper end of the heating chamber 3.
[0026] From the analysis of the above structure, it can be known that when the temperature of the water inside the heating chamber 3 is too high, causing the pressure inside the heating chamber 3 to be too high, the pressure will be discharged through the safety valve 21.
[0027] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the heating chamber 3, the sewage chamber 6 and the external leakage position of the heating coil 10 are all wrapped with an insulation layer.
[0028] From the analysis of the above structure, it can be seen that the heat preservation layer wrapped around the outer surface of the heating chamber 3, the sewage chamber 6 and the heating coil 10 prevents the internal heat from being lost and reduces the energy loss.
[0029] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer surface of the capillary 11 is provided with a protective shell 22.
[0030] From the analysis of the above structure, it can be known that the protective shell 22 sleeved on the outer surface of the capillary 11 prevents the capillary 11 from being hit during movement or transportation, thereby preventing the capillary 11 from bending and deforming.
[0031] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the lower right end of the sewage chamber 6 is connected to an adjustment water outlet 23, and a water pump 24 is connected to the pipeline of the adjustment water outlet 23. The controller 2 is electrically connected to the water pump 24.
[0032] From the analysis of the above structure, it can be seen that the outlet water temperature inside the sewage chamber 6 is set by the controller 2. When the temperature inside the sewage chamber 6 is lower than the set temperature, the water pump 24 will be started to quickly pump out the water inside the sewage chamber 6.
[0033] like Figure 1-4 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a stop valve 25 is provided at the connection between the heat-conducting coil 10 and the capillary 11 inside the heating chamber 3 and at the connection between the compressor 9 and the heat-conducting coil 10 inside the heating chamber 3.
[0034] From the analysis of the above structure, it can be known that the required temperature inside the heating chamber 3 is set by the controller 2. When the temperature detector inside the heating chamber 3 detects that the temperature reaches the set temperature, the stop valve 25 at the connection of the heat transfer coil 10 inside the heating chamber 3 will be closed first. When the compressor 9 extracts the refrigerant inside the heat transfer coil 10 in the heating chamber 3, the other stop valve 25 will be closed, and then the compressor 9 will be turned off to complete the shutdown.
[0035] like Figure 1-4As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the heating chamber 3 and the sewage chamber 6 are both made of stainless steel, and the heating coil 10 is made of copper.
[0036] From the analysis of the above structure, it can be seen that the heating chamber 3 and the sewage chamber 6 are both made of stainless steel, which can prevent the inside of the heating chamber 3 and the sewage chamber 6 from rusting and affecting the water quality. The heating coil 10 is made of copper, which has better thermal conductivity and can quickly conduct heat.
