Description

Technical Field

[0001] This invention relates to the field of wastewater source heat pumps, and more specifically to a wastewater source heat pump device that is beneficial for energy conservation and emission reduction. Background Technology

[0002] A water source heat pump is a type of integrated water-to-water / water-to-air air conditioning unit that uses water as the medium for cooling / heating cycles. Water source heat pump units use water as the heat source during heating and water as the heat exhaust source during cooling. The advantages of using water as the heat source are: water has a large heat capacity, good heat transfer performance, requires less water to transfer a certain amount of heat, has a compact heat exchanger size, costs less per square meter of building area compared to air-to-air heat pumps, does not frost, has relatively small water temperature fluctuations, and operates stably. Wastewater source heat pump units, in particular, utilize wastewater for reuse.

[0003] Existing wastewater source heat pump equipment suffers from low efficiency due to relying solely on a single pump for water extraction. Furthermore, the inability to alternate pumps at the front end leads to prolonged operation and overheating, resulting in damage. Additionally, the system only performs filtration without timely cleaning of the filter screen, further reducing extraction efficiency. Moreover, scale buildup on the heating elements during wastewater heating deteriorates, reducing heating efficiency. Therefore, we propose a wastewater source heat pump system that promotes energy conservation and emission reduction. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a wastewater source heat pump device that is conducive to energy saving and emission reduction. It can solve the problems of low water pumping efficiency when using existing wastewater source heat pump devices, the inability of the water pumps used for front-end water pumping to operate alternately, resulting in damage due to excessive heat during long-term operation, and the inability to clean the filter screen in time when pumping wastewater, which leads to low water pumping efficiency. In addition, the scale generated on the heating pipes when heating wastewater cannot be cleaned in time, which leads to low heating efficiency.

[0013] According to another aspect of the present invention, a wastewater source heat pump system that is beneficial for energy saving and emission reduction is provided, comprising a first water pump, a controller, an evaporator, a compressor, a second water pump, a solenoid valve, a temperature sensor, and a heating plate, wherein the controller is electrically connected to the first water pump, the evaporator, the compressor, the second water pump, the solenoid valve, the temperature sensor, and the heating plate.

[0014] The beneficial effects of the wastewater source heat pump equipment of the present invention, which is conducive to energy conservation and emission reduction, are as follows:

[0015] This invention, through the arrangement of a filtration mechanism, a water pump 1, a heating mechanism, a controller, an evaporator, a compressor, a water pump 2, a heat exchanger, a T-connector 1, a T-connector 2, a solenoid valve, and a connecting pipe, allows the wastewater source to be connected to the filtration mechanism via an external pipe when the T-connector 1, T-connector 2, and connecting pipe are in operation. Then, the controller activates either of the two water pumps 1 to pump water, and then activates water pump 2 to assist in pumping. The wastewater is first drawn into the heating mechanism by the water pump 1 for heating, and then flows into the evaporator to evaporate, turning the wastewater into steam, which then enters the... The compressor increases the gas pressure, turning the steam into a high-temperature, high-pressure state to achieve a heating effect. Finally, the steam enters the heat exchanger for heat exchange. This setup allows the wastewater source heat pump equipment to use a controller to start one of the two solenoid valves during operation, thereby starting the corresponding water pump. When the water pump has been used for too long and the temperature is too high, the other solenoid valve can be opened to start the other water pump, thus achieving the effect of alternating use of the two water pumps for cooling and avoiding the problem of water pump damage due to prolonged operation.

[0016] In this invention, the filter mechanism comprises a filter box, partition, inlet, filter screen, shaft one, rotating rod one, rotating rod two, connecting rod, shaft two, sealing rotating plate one, sealing rotating plate two, spiral blades, elastic belt, and striking ball. Through rotating holes one and two, the filter box is divided into two parts. When the two water pumps start, filtration is performed through two different filter screens inside the filter box. When the water pumps start pumping water, they drive the spiral blades at the corresponding filter screens to rotate, thereby driving the striking ball at the end of the elastic belt to rotate, thus striking the filter screen and knocking off the debris adhering to the filter screen, avoiding the problem of filter screen clogging after long-term use. Furthermore, the rotation of rotating rod one will drive shaft one to rotate, and the rotation of rotating rod two will drive shaft two to rotate.

[0017] This invention, through the arrangement of a cam, drain outlet, U-shaped rod, sealing plate, movable connecting groove, fixing plate, pneumatic cylinder, piston plate, anti-detachment latch, anti-detachment block, push rod, through port, L-shaped stop rod, sealing plate, vertical rod, connecting column, spring one, hollow tube, connector, and hose, allows the L-shaped stop rod to reciprocate left and right under the action of spring one when the cam rotates. This, in turn, pushes the push rod to reciprocate left and right. When the push rod moves to the left, the connecting column at the bottom of the vertical rod first moves horizontally along the movable connecting groove. After the sealing plate comes into contact with the piston plate, the piston plate moves along the pneumatic cylinder, and then... The air pressure inside the air cylinder is filled into the hollow tube, causing the connector to descend and the right side of the sealing plate to gradually tilt downwards, making it easier for the collected garbage to be discharged from the drain. By repeatedly pulling the sealing plate, it is easier to shake off the garbage. Furthermore, due to the rotation of the cam, the rotation of the first rotating rod will drive the first shaft to rotate, and the rotation of the second rotating rod will drive the second shaft to rotate. When the water flow drives the spiral blades behind the baffle to rotate, the cam in front will rotate, which will clean up the garbage in front of the baffle. Conversely, it will clean up the garbage behind the baffle, so that the garbage cleaning process does not affect the water pumping in.

[0018] This invention utilizes an annular groove, a positioning port, a circular tube, a scraper, a circular rod, turbine blades, a transverse groove, a positioning rod, and a second spring. When water flows through the inlet pipe, the impact of the water flow causes the circular rod to slide to the right along the inside of the circular tube. This moves the positioning rod to the inside of the annular groove. The water flow impact then causes the turbine blades to rotate, which in turn causes the scraper to rotate, scraping away dirt from the heating plate surface and ensuring its heating effect. When the water flow stops, the positioning rod, pushed by the second spring, re-engages in the positioning port, preventing the turbine blades from rotating and ensuring the stability of the scraper, preventing it from easily moving.

The right side of the filter mechanism 1 is connected to the right end of the input end of the two water pumps 2 through the three-way pipe 9. The output ends of the two water pumps 2 are fixedly connected to the opposite ends of the two solenoid valves 11 through the connecting pipe 12. The opposite ends of the two solenoid valves 11 are fixedly connected to the left side of the heating mechanism 3 through the three-way pipe 10. The controller 4 is fixedly installed on the upper surface of the heating mechanism 3. The right end of the heating mechanism 3 is fixedly connected to the left end of the evaporator 5 through the connecting pipe 12. The compressor 6 and the water pump 7 are fixedly connected to the inside of the evaporator 5 through the two connecting pipes 12, respectively. The compressor 6 and the water pump 7 are respectively connected to the heat exchanger 8 through the two connecting pipes 12.

[0031] In this embodiment, the filtration mechanism 1 includes a filter box 101, a partition 102, an inlet 103, a filter screen 104, a first shaft 105, a first rotating rod 106, a second rotating rod 107, a connecting rod 108, a second shaft 109, a first sealing rotating plate 110, a second sealing rotating plate 111, a spiral blade 112, an elastic band 113, and a striking ball 114. The partition 102 is fixedly connected between the left side of the filter box 101 and the right side of the three-way pipe 9. A through-hole 14 is provided on the front surface of the partition 102. Two inlets 103 are integrally formed on the left side of the filter box 101. Filter screens 104 are fixedly installed inside the filter box 101, both in front of and behind the filter screens 104. The front surface of the filter box 101 has a second rotating hole 15. Inside the rear of the filter box 101, to the left of the filter screen 104, a shaft 105 is rotatable via a pivot. The front end of the shaft 105 passes through the first rotating hole 14 and is fixedly connected to a rotating rod 106 in front of the partition plate 102. On the rear surface of the filter box 101, outside the shaft 105, a rotating rod 107 is rotatably connected via a pivot. The front end of the rotating rod 107 is fixedly connected to a connecting rod 108. The outer wall of the connecting rod 108 is located inside the first rotating hole 14 and outside the shaft 105. A sealing rotating plate 110 is fixedly connected to the outer wall of the connecting rod 108, inside the second rotating hole 15.

A striking ball 114 is fixedly connected to the end of each elastic band 113 away from the first rotating rod 106 and the second rotating rod 107. The filter mechanism 1 in this invention comprises a filter box 101, a partition 102, an inlet 103, a filter screen 104, a shaft 105, a rotating rod 106, a second rotating rod 107, a connecting rod 108, a shaft 109, a sealing rotating plate 110, a sealing rotating plate 111, and spiral blades 112. 2. The elastic band 113 and the striking ball 114, through the rotating holes 14 and 15, divide the filter box 101 into two parts. When the two water pumps 12 are started, the filter is filtered through two different filter screens 104 inside the filter box 101. When the water pump 12 starts pumping water, it will drive the spiral blades 112 at the corresponding filter screen 104 to rotate, thereby driving the striking ball 114 at the end of the elastic band 113 to rotate, thus knocking the filter screen 104 and knocking off the debris adhering to the filter screen 104, avoiding the problem of long-term clogging of the filter screen 104. In addition, the rotation of the rotating rod 106 will drive the shaft 105 to rotate, and the rotation of the rotating rod 107 will drive the shaft 109 to rotate.

[0032] In this embodiment, cams 16 are fixedly connected to the rear end of shaft 105 and the front end of shaft 109. A through-type drain port 17 is symmetrically opened on the lower surface of the filter box 101 on the left side of the filter screen 104. U-shaped rods 18 are fixedly connected to the left side of the two drain ports 17 on the lower surface of the filter box 101. A sealing plate 19 is rotatably connected to the outer wall of the U-shaped rod 18. The upper surface of the sealing plate 19 is in contact with the lower surface of the filter box 101. Movable connecting grooves 20 are opened on the opposite sides of the two sealing plates 19. Fixing plates 21 are fixedly connected to the front and rear surfaces of the filter box 101. A pneumatic cylinder 22 is fixedly connected to the right side of the fixing plate 21. A piston plate 23 is slidably connected inside the pneumatic cylinder 22. A protective opening is opened on the left side of the piston plate 23. The anti-detachment latch 24 has an anti-detachment block 25 on its inner side. A push rod 26 is fixedly connected to the right side of the anti-detachment block 25. An opening 27 is opened on the right side of the air cylinder 22. The right end of the push rod 26 passes through the right side of the piston plate 23 and through the right side of the opening 27, and is fixedly connected to an L-shaped abutment rod 28. A sealing plate 29 is fixedly connected to the outer wall of the push rod 26. A vertical rod 30 is fixedly connected to the outer wall of the push rod 26. The bottom end of the vertical rod 30 is integrally formed with a connecting column 31 inside the movable connecting groove 20. The right end of the L-shaped abutment rod 28 contacts the outer wall of the cam 16. A spring 32 is symmetrically fixedly connected between the L-shaped abutment rod 28 and the fixed plate 21. Hollow cores are fixedly connected to the front and rear surfaces of the filter box 101 below the L-shaped abutment rod 28. The hollow tube 33 has a connector 34 slidably connected inside. The opposite sides of the two connectors 34 are rotatably connected to the opposite sides of the two sealing plates 19 via rotating shafts. A hose 48 is fixedly connected between the air cylinder 22 and the hollow tube 33. The present invention, through the arrangement of cam 16, drain port 17, U-shaped rod 18, sealing plate 19, movable connecting groove 20, fixing plate 21, air cylinder 22, piston plate 23, anti-detachment latch 24, anti-detachment block 25, push rod 26, through port 27, L-shaped abutment 28, sealing plate 29, vertical rod 30, connecting column 31, spring 32, hollow tube 33, connector 34 and hose 48, allows the L-shaped abutment 28 to move back and forth under the action of spring 32 when cam 16 rotates, thereby pushing the push rod 28. As rod 26 moves back and forth, when push rod 26 moves to the left, connecting post 31 at the bottom of vertical rod 30 moves horizontally along movable connecting groove 20. After sealing plate 29 is in contact with piston plate 23, piston plate 23 moves along air cylinder 22, and then the air pressure inside air cylinder 22 is filled into hollow tube 33, causing connector 34 to descend, making the right side of sealing plate 19 gradually tilt downward, thus facilitating the discharge of collected garbage from drain port 17. By repeatedly pulling sealing plate 19, it is easier to shake off garbage. Furthermore, due to the rotation of cam 16, the rotation of rotating rod 106 will drive shaft 105 to rotate, and the rotation of rotating rod 107 will drive shaft 109 to rotate, causing the water flow to drive the spiral blades 112 behind baffle 102 to rotate.The front cam 16 rotates, clearing debris in front of the baffle 102 and conversely, clearing debris behind the baffle 102, ensuring that the debris clearing process does not affect water pumping.

[0033] In this embodiment, a flange 35 is fixedly connected to the left end of the water inlet 103 to facilitate connection to an external water pumping pipe.

[0034] In this embodiment, a temperature sensor 13 is fixedly installed on the top of the water pump 2 to sense the temperature of the water pump 2, so that the controller 4 can control the water pump 2 to shut down when the temperature is too high.

[0035] In this embodiment, the heating mechanism 3 includes a heating box 301, a water inlet pipe 302, a drain pipe 303, and a heating plate 304. The water inlet pipe 302 and the drain pipe 303 are integrally formed on the left and right sides of the heating box 301, respectively. Multiple heating plates 304 are fixedly installed on the inner side wall of the heating box 301. The water inlet pipe 302 is a hollow cylindrical structure with an opening on the left side. Multiple water inlet holes 36 are opened on the right side of the water inlet pipe 302. Sewage enters the interior of the heating box 301 through the water inlet holes 36 of the water inlet pipe 302, and after being heated by the heating plate 304, it flows out from the drain pipe 303.

[0036] In this embodiment, the heating box 301 has an integrally formed hollow cavity 37, and the hollow cavity 37 is embedded with a heat insulation layer 38, which has a heat insulation effect and reduces heat loss.

[0037] In this embodiment, an annular groove 39 is formed on the inner wall of the water inlet pipe 302, and a positioning port 40 is integrally formed on the inner wall of the annular groove 39. A circular pipe 41 is rotatably connected to the inner right side of the water inlet pipe 302 via a rotating shaft. A scraper 42 is fixedly connected to the right end of the circular pipe 41 inside the heating box 301. A circular rod 43 is slidably connected to the inside of the circular pipe 41, and a turbine blade 44 is fixedly connected to the right end of the circular rod 43. A through transverse groove 45 is formed on the outer wall of the circular pipe 41, and a positioning rod 46 is fixedly connected to the right end of the circular rod 43 inside the transverse groove 45. A spring 47 is fixedly connected between the positioning rod 46 and the circular pipe 41. The top end of the positioning rod 46 is engaged with the inner side of the positioning port 40. The present invention utilizes the annular groove 39 and the positioning port 40 to achieve the desired effect. The components of the inlet 40, circular tube 41, scraper 42, circular rod 43, turbine blade 44, transverse groove 45, positioning rod 46, and spring 47 work together to ensure that when water flows through the inlet pipe 302, the circular rod 43 slides to the right along the inside of the circular tube 41 under the impact of the water flow. This causes the positioning rod 46 to move to the inside of the annular groove 39. At this time, the impact of the water flow causes the turbine blade 44 to drive the circular tube 41 to rotate, thereby causing the scraper 42 to rotate and scrape off the dirt on the surface of the heating plate 304, ensuring the heating effect of the heating plate 304. When the water flow stops, the positioning rod 46 will re-engage in the positioning inlet 40 under the push of spring 47, preventing the turbine blade 44 from rotating and ensuring the stability of the scraper 42, preventing it from moving easily.

[0038] According to another aspect of the present invention, a wastewater source heat pump system that is beneficial for energy saving and emission reduction is provided, including a water pump 2, a controller 4, an evaporator 5, a compressor 6, a water pump 7, a solenoid valve 11, a temperature sensor 13, and a heating plate 304. The controller 4 is electrically connected to the water pump 2, the evaporator 5, the compressor 6, the water pump 7, the solenoid valve 11, the temperature sensor 13, and the heating plate 304.

[0039] The working principle of this device is as follows: This invention, through the configuration of a filter mechanism 1, a water pump 2, a heating mechanism 3, a controller 4, an evaporator 5, a compressor 6, a water pump 7, a heat exchanger 8, a three-way pipe 9, a three-way pipe 10, a solenoid valve 11, and a connecting pipe 12, allows the wastewater source to be connected to the filter mechanism 1 via an external pipe, with the three-way pipe 9, the three-way pipe 10, and the connecting pipe 12 in operation. Then, the controller 4 starts either of the two water pumps 2 to pump water, and then the second water pump 7 is started to assist in pumping water. The wastewater is first drawn into the heating mechanism 3 by the water pump 2 for heating, and then flows into the evaporator 5 for evaporation. The process involves converting wastewater into steam, which then enters the compressor 6, increasing the gas pressure and creating a high-temperature, high-pressure steam that achieves a heating effect. Finally, the steam enters the heat exchanger 8 for heat exchange. This setup allows the wastewater source heat pump equipment to operate by controlling one of the two solenoid valves 11 via the controller 4, which in turn starts the corresponding water pump 2. When the water pump 2 has been in use for too long and its temperature is too high, the other solenoid valve 11 can be opened to start the other water pump 2, thus achieving an alternating cooling effect between the two water pumps 2 and preventing damage from prolonged operation of the water pump 2.
