Description

Technical Field

[0001] This utility model relates to ground source heat pumps, specifically a ground source heat pump circulating water continuous filtration device. Background Technology

[0002] Currently, ground source heat pumps are widely used in office buildings for summer cooling and winter heating. They are significantly more economical than central air conditioning. When a ground source heat pump is running, it needs to conduct heat through circulating water. The circulating water needs to pass through a filter screen when it flows through the water storage tank to filter out particulate impurities such as dust and rust carried in the water. Since the circulating water circulates continuously for 24 hours throughout the entire cooling or heating cycle, the filter screen is easily clogged, which reduces the filtration effect or even causes it to fail.

[0003] In addition, since the circulating water cannot be stopped, the machine is turned on when the filter screen is replaced. This makes it easy for impurities filtered out to fall into the water storage tank during the process of removing the filter screen, which will re-contaminate the circulating water. Moreover, the workers' clothes will get wet every time the filter screen is replaced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a ground source heat pump circulating water continuous filtration device. By continuously releasing the wound filter cloth, the traditional operation of replacing the filter screen is replaced. This not only eliminates the tedious steps of replacement but also achieves continuous and effective filtration throughout the entire cooling or heating cycle.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0017] like Figures 1 to 3 A ground source heat pump circulating water continuous filtration device includes a water storage tank 1. The middle of the water storage tank 1 is divided into a sedimentation chamber 8 and a filtration chamber by a longitudinal partition 15. An overflow port 19 is provided at the top of the longitudinal partition 15, and a water inlet 2 is provided in the middle of the sedimentation chamber 8.

[0018] The middle of the filter chamber is divided into an upper separation chamber 11 and a lower return water chamber 14 by a horizontal partition 13. A set of flow holes are provided on the horizontal partition 13.

[0019] The return water tank 14 is connected to an outlet 7. Both the outlet 7 and the inlet 2 are equipped with flanges at their outer edges to facilitate connection with the circulating water pipeline of the ground source heat pump unit.

[0020] The bottom sides of the separation chamber 11 are rotatably connected to limit shafts 20, and the top sides of the filter chamber are respectively provided with a first bracket group 10 and a second bracket group 9.

[0021] The first bracket group 10 is rotatably connected to a winding roller 17, and the first bracket group 10 is also equipped with a motor 4 that drives the winding roller 17 to rotate. The second bracket group 9 is rotatably connected to a release roller 18, on which a roll of filter cloth 16 is fitted. The filter cloth 16 is made of non-woven fabric, and the free end of the filter cloth 16 passes through two limiting shafts 20 and is connected to the winding roller 17.

[0022] Working principle:

[0023] When in use, connect the circulating water pipe of the ground source heat pump unit to the inlet 2 and the outlet 7 respectively;

[0024] The circulating water enters the sedimentation tank 8 through the inlet 2 and settles in the sedimentation tank 8. The water in the sedimentation tank 8 overflows through the overflow outlet 19 into the separation tank 11, then is filtered by the filter cloth 16 and falls into the return water tank 14, and then is discharged from the outlet 7 for use.

[0025] The filter cloth 16 laid at the bottom of the separation chamber 11 serves a filtering function. When a lot of impurities are attached to this part of the filter cloth 16, the motor 4 is turned on to drive the winding roller 17 to rotate, thereby winding the filter cloth 16 with the attached dirt onto the winding roller 17, and at the same time laying a new part at the bottom of the separation chamber 11 to serve a filtering function.

[0026] This utility model uses a method of winding the filter cloth 16 to collect the part of the filter cloth 16 with attached dirt, and then lays the new part of the filter cloth 16 at the bottom of the separation chamber 11 for filtration. By continuously repeating the above steps, the filtration effect is effectively guaranteed.

[0027] This design not only eliminates the tedious steps of regularly replacing the filter in traditional operations, greatly improving work efficiency, but also enables continuous and effective filtration throughout the entire cooling or heating cycle with just one roll of filter cloth. It is simpler and more convenient to use, and is more compatible with 24-hour uninterrupted water circulation.

[0028] In addition, as a further preferred embodiment, a first drain valve 3 is provided at the bottom of the sedimentation tank 8. The sediment at the bottom of the sedimentation tank 8 can be discharged by periodically opening the first drain valve 3.

[0029] The bottom of the separation chamber 11 is equipped with a second drain valve 6. By periodically opening the second drain valve 6, some large particles of impurities that are difficult to adhere to the surface of the filter cloth 16 can be discharged from the separation chamber 11. Example 2

[0030] This embodiment is a further optimization based on the above embodiment, specifically:

[0031] like Figures 1 to 3 A controller 5 is provided on the outside of the water storage tank 1. The controller 5 is electrically connected to the motor 4. A liquid level sensor 12 is installed in the filter chamber. The liquid level sensor 12 is installed at a position slightly lower than the overflow port 19. The liquid level sensor 12 is electrically connected to the controller 5.

[0032] This design enables automatic winding of the filter cloth 16. Specifically, when impurities accumulate on the portion of the filter cloth 16 laid in the filter chamber, causing some blockage, the water level in the filter chamber rises. When the water level touches the level sensor 12, the level sensor 12 transmits a signal to the controller 5, which then controls the motor 4 to rotate, thereby winding the old portion of the filter cloth 16 and laying the new portion. This increases the water permeability, causing the liquid level in the separation chamber 11 to drop. When the water level no longer touches the level sensor 12, the controller 5 controls the motor 4 to stop.

[0033] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
