Description

Technical Field

[0001] The present invention relates to the technical field of water source heat pumps, in particular to a high-efficiency industrial heat pump heat energy recovery device. Background Art

[0002] A water source heat pump is a device that works on the principle of reverse Carnot cycle. It can transfer heat from a low-temperature heat source to a high-temperature heat source. When the heat pump is working, the refrigerant will flow in the heat exchange tubes inside the evaporator, and the water source will flow directly in the evaporator shell outside the heat exchange tubes, so that the refrigerant absorbs heat to achieve heat energy recovery. Subsequently, the refrigerant in the evaporator will work with the compressor and condenser to send heat into the room.

[0003] When in use, water source heat pumps usually directly extract groundwater, which may pump sewage or water containing more impurities into the evaporator. After long-term use, the outer wall of the refrigerant tube of the evaporator will be scaled, reducing heat conductivity and resulting in extremely low heat transfer efficiency. Therefore, it is necessary to use hydrochloric acid and other cleaning agents to clean the inside of the evaporator. However, it is difficult to completely remove the scale by soaking in the cleaning agent alone. Disassembling the refrigerant tube will easily cause the refrigerant to flow out and cause waste, and the cleaning effect is poor. Moreover, the heat pump needs to be stopped when cleaning the inside of the evaporator, which affects the heat recovery efficiency. Summary of the Invention

[0004] The present invention provides a high-efficiency industrial heat pump heat energy recovery device, which can remove the refrigerant pipe and brush it, thereby improving the cleaning effect, and can also avoid the refrigerant in the refrigerant pipe from flowing out and causing waste.

[0009] Among them, a spring is provided on the outside of the sealing guide rod, which can push the sealing plug to slide to the right. The right side of the sealing plug is a hemispherical structure. The right end of the refrigerant tube is provided with an opening with a curved inner wall, and when the sealing plug slides to the far right, it will be tightly attached to the inner wall of the opening at the right end of the refrigerant tube.

[0019] Example 1: Please refer to Figures 1 to 8 : The present invention proposes a high-efficiency industrial heat pump heat energy recovery device, comprising: a base 1; Two evaporator shells 2 are installed on the top of the base 1 through a bracket. A water inlet pipe 3 is connected to the right side of the top of the evaporator shell 2, and a water outlet pipe 4 is connected to the left side of the top of the evaporator shell 2. The base 1 is used to support the upper part of the structure of the device. The evaporator shell 2 is used to hold groundwater and recover heat energy. The water inlet pipe 3 is used to introduce groundwater into the evaporator shell 2, and the water outlet pipe 4 is used to guide the groundwater in the evaporator shell 2 outward; an adjusting shell 5 is fixed to the top of the two water inlet pipes 3 by welding, and a water inlet cover 6 is fixed on the top of the adjusting shell 5. An adjusting disk 7 is rotatably installed on the inside of the adjusting shell 5, and the outside of the adjusting disk 7 is also connected to a A cleaning pipe 8 is provided, and the adjusting shell 5 is used to support the rotation of the adjusting dial 7. When the water pump is running, groundwater will be pumped into the cavity inside the water inlet cover 6. When in use, the cleaning pipe 8 can be held to rotate the adjusting disc 7 inside the adjusting shell 5. After rotation, one of the evaporator shells 2 can be passed through water for heat recovery, and the other evaporator shell 2 can be cleaned; a cover plate 9 is installed on the left side of the evaporator shell 2 through a nut and a screw rod, and a refrigerant pipe 10 is fixed to the right side of the cover plate 9. The cover plate 9 is used to support the refrigerant pipe 10, and the refrigerant pipe 10 is used to transport the refrigerant; two refrigerant joints 11 are also fixed on the right side of the evaporator shell 2, and the upper A refrigerant inlet pipe 12 is screwed to the outside of the refrigerant joint 11 at the top by a thread, and a refrigerant discharge pipe 13 is screwed to the outside of the refrigerant joint 11 at the bottom by a thread. When in use, the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 can be screwed to the outside of the refrigerant joint 11 on the evaporator shell 2. The refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 cooperate with the condenser and the compressor to circulate the refrigerant and recover heat energy; a sealing guide rod 14 is slidably installed on the inside of the two openings at the right end of the refrigerant conduit 10, and a sealing plug 15 is fixed on the sealing guide rod 14. A push rod 1 is also fixed to the inside of the openings at the left end of the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13. 6. During the process of screwing the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13, the left end of the push rod 16 inside will first contact the sealing guide rod 14 in the opening at the right end of the refrigerant pipe 10 and push the sealing guide rod 14 to slide to the left, thereby disengaging the sealing plug 15 from the opening at the right end of the refrigerant pipe 10, thereby connecting the cavity inside the refrigerant pipe 10 with the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13. When the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 are unscrewed, the spring outside the sealing guide rod 14 will push the sealing plug 15 back to the rightmost position, thereby sealing the opening at the right end of the refrigerant pipe 10, thereby preventing the refrigerant in the refrigerant pipe 10 from leaking out.

[0020] In this embodiment, Figure 2-Figure 4As shown, the cover plate 9 is composed of two circular plates on the left and right. The outer diameter of the right circular plate is 5 cm smaller than that of the left circular plate, and a semicircular plate is provided on the top and bottom of the left circular plate. Therefore, the cover plate 9 can be limited when installed, and the semicircular plates on the top and bottom of the left circular plate of the cover plate 9 can also achieve blind operation when the right end of the refrigerant pipe 10 is installed.

[0021] In this embodiment, Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, two annular plates are fixed to the outer wall of the right part of the refrigerant conduit 10. After the cover plate 9 is installed, the right end of the refrigerant conduit 10 will be embedded in the inner side of the refrigerant joint 11 and tightly fit against the inner wall of the refrigerant joint 11. In addition, the annular plates on the outer wall of the refrigerant conduit 10 will also be tightly fit against the right inner wall of the evaporator shell 2. Therefore, after the cover plate 9 is installed, the refrigerant conduit 10 can be connected to the refrigerant joint 11, and the annular plates on the outer wall of the refrigerant conduit 10 can play a sealing role at the joint position.

[0022] In this embodiment, Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, a cylindrical cavity is provided on the inner side of the regulating shell 5, and the outer wall of the regulating disc 7 is in close contact with the inner wall of the cylindrical cavity inside the regulating shell 5. An arc-shaped opening is also provided on the right outer wall of the regulating shell 5, and the cleaning pipe 8 can be displaced in the arc-shaped opening. When in use, the cleaning pipe 8 can be held to rotate and adjust the regulating disc 7 on the inner side of the regulating shell 5. After rotation, water can be passed through one of the evaporator shells 2 for heat recovery, and the other evaporator shell 2 can be cleaned.

[0023] In this embodiment, Figure 7 and Figure 8As shown, a spring is provided on the outside of the sealing guide rod 14, which can push the sealing plug 15 to slide to the right. The right side of the sealing plug 15 is a hemispherical structure. The right end of the refrigerant pipe 10 is provided with two openings with curved inner walls, and when the sealing plug 15 slides to the rightmost side, it will be in close contact with the inner wall of the opening at the right end of the refrigerant pipe 10. After the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 are screwed together on the outside of the refrigerant joint 11, the push rod 16 will push the sealing guide rod 14 to the left and disengage the sealing plug 15 from the opening at the right end of the refrigerant pipe 10, so as to prevent the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 from being screwed together. The left end of the push rod 16 will first contact the sealing guide rod 14 in the opening at the right end of the refrigerant pipe 10 and push the sealing guide rod 14 to slide to the left, thereby disengaging the sealing plug 15 from the opening at the right end of the refrigerant pipe 10, thereby connecting the cavity inside the refrigerant pipe 10 with the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13. When the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 are unscrewed, the spring outside the sealing guide rod 14 will push the sealing plug 15 back to the rightmost side, thereby sealing the opening at the right end of the refrigerant pipe 10, thereby preventing the refrigerant in the refrigerant pipe 10 from leaking out.

[0024] In this embodiment, Figure 5 and Figure 6 As shown, two circular holes are provided on the top and bottom of the regulating shell 5, and the two circular holes on the top of the regulating shell 5 connect the cavity inside the water inlet cover 6 with the cavity inside the regulating shell 5, and the two circular holes at the bottom of the regulating shell 5 connect the cavity inside the regulating shell 5 with the two water inlet pipes 3. During use, the groundwater in the water inlet cover 6 will flow downward into the water inlet pipe 3 through the circular holes on the top and bottom of the regulating shell 5 and the vertical hole inside the regulating disc 7, and then the groundwater will enter the evaporator shell 2 on the rear side and evenly contact the outer wall of the refrigerant conduit 10. When cleaning the inside of the evaporator shell 2, the hydrochloric acid cleaning agent can be introduced into the cleaning pipe 8. At this time, the hydrochloric acid cleaning agent will flow downward into the water inlet pipe 3 through the circular holes on the top and bottom of the regulating shell 5 and the L-shaped hole inside the regulating disc 7, and then the hydrochloric acid cleaning agent will enter the inside of the evaporator shell 2 at the rear side.

[0025] In this embodiment, Figure 5 and Figure 6As shown, a vertical circular hole and an L-shaped hole are provided inside the adjusting disc 7, the top of the L-shaped hole is connected to the cleaning pipe 8, and when the cleaning pipe 8 outside the adjusting disc 7 is rotated to the front or rear side, the bottoms of the two holes inside the adjusting disc 7 will be connected to the two water inlet pipes 3 respectively. During use, the groundwater in the water inlet cover 6 will flow downward into the water inlet pipe 3 through the circular holes at the top and bottom of the adjusting shell 5 and the vertical hole inside the adjusting disc 7, and then the groundwater will enter the evaporator shell 2 at the rear side and evenly contact the outer wall of the refrigerant conduit 10. When cleaning the inside of the evaporator shell 2, hydrochloric acid cleaning agent can be introduced into the cleaning pipe 8, and at this time, the hydrochloric acid cleaning agent will flow downward into the water inlet pipe 3 through the circular holes at the top and bottom of the adjusting shell 5 and the L-shaped hole inside the adjusting disc 7, and then the hydrochloric acid cleaning agent will enter the inside of the evaporator shell 2 at the rear side.

[0026] Example 2, based on Example 1, Figures 1-8 As shown, the top and bottom outer walls of the adjusting disc 7, the right outer wall of the cover plate 9, the outer side of the annular plate on the outer wall of the refrigerant pipe 10, and the outer wall of the sealing plug 15 are all wrapped with a layer of rubber. Therefore, the gaps at the bottom and top of the adjusting disc 7 will not leak groundwater to the outside. The sealing can be ensured after the cover plate 9 is installed. After the refrigerant pipe 10 is installed, the rubber on the outer side of the annular plate on its outer wall will also be in close contact with the right inner wall of the evaporator shell 2 to ensure sealing. The rubber on the outer side of the sealing plug 15 cooperates with the opening at the right end of the refrigerant pipe 10 to ensure sealing.

[0027] The working principle of this embodiment is as follows: during installation, the base 1 can be fixed on one side of the heat pump, and the round pipe at the top of the water inlet cover 6 can be connected to the water pump, the water outlet pipe 4 can be connected to the groundwater return pipe, the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 can be connected to the condenser and the compressor respectively, and the refrigerant can be pre-added to the refrigerant conduit 10. When the heat pump needs to be turned on, the cleaning pipe 8 can be first held and the adjusting disc 7 can be rotated and the cleaning pipe 8 can be rotated to the front. At this time, the vertical hole inside the adjusting disc 7 will be located directly above the water inlet pipe 3 at the top of the evaporator shell 2 on the rear side, and the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 can be screwed to the outside of the refrigerant joint 11 on the evaporator shell 2 on the rear side, and the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 can be screwed to the outside of the refrigerant joint 11 on the evaporator shell 2 on the rear side. During the screwing process of the discharge pipe 13, the left end of the top rod 16 inside it will first contact the sealing guide rod 14 in the opening at the right end of the refrigerant pipe 10 and push the sealing guide rod 14 to slide to the left, so that the sealing plug 15 can be disengaged from the opening at the right end of the refrigerant pipe 10, thereby connecting the cavity inside the refrigerant pipe 10 with the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13. Then the water pump and the compressor can be turned on. When the water pump is running, the groundwater will be pumped into the cavity inside the water inlet cover 6, and then the groundwater in the water inlet cover 6 will flow downward into the water inlet pipe 3 through the circular holes at the top and bottom of the regulating shell 5 and the vertical hole inside the regulating disc 7. Then the groundwater will enter the evaporator shell 2 on the rear side and evenly contact the outer wall of the refrigerant pipe 10. When the compressor is working, the refrigerant will circulate in the refrigerant pipe 10, so that the refrigerant can absorb the heat in the groundwater and transfer it to the condenser to realize heat recovery. Finally, the groundwater will be discharged outward through the outlet pipe 4 to realize circulation. When it is necessary to clean the scale inside the evaporator shell 2 on the rear side, you can hold the cleaning pipe 8 and rotate it to the rear side, and unscrew the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 and re-screw them on the outside of the refrigerant joint 11 on the evaporator shell 2 on the front side, so that heat recovery can continue through the evaporator shell 2 on the front side, and when the refrigerant inlet pipe 12 and the refrigerant discharge pipe 13 are unscrewed, the spring on the outside of the sealing guide rod 14 will push the sealing plug 15 to move back Move to the far right, so that the opening at the right end of the refrigerant conduit 10 can be closed, thereby preventing the refrigerant in the refrigerant conduit 10 from leaking outward, and then the hydrochloric acid cleaning agent can be introduced into the cleaning pipe 8. At this time, the hydrochloric acid cleaning agent will flow downward into the water inlet pipe 3 through the circular holes at the top and bottom of the adjusting shell 5 and the L-shaped hole inside the adjusting disk 7. Then the hydrochloric acid cleaning agent will enter the interior of the evaporator shell 2 at the rear side, so that the inner wall of the evaporator shell 2 and the outer wall of the refrigerant conduit 10 can be soaked to achieve descaling, and the nut on the left side of the cover plate 9 can be removed, and then the cover plate 9 can be removed and the refrigerant conduit 10 can be pulled out to the left, so that the refrigerant conduit 10 can be brushed to improve the cleaning effect.
