Description

Technical Field

[0001] The invention relates to the technical field of pre-filtration of water source heat pumps, in particular to a water source heat pump filtering device. Background Art

[0002] Water source heat pump systems use water as a cold or heat source to provide cooling or heating for buildings through heat exchange devices. To ensure the efficient operation of the system, a pre-filter device is usually installed at the water inlet of the water source heat pump to intercept sediment, suspended matter and other impurities in the water. However, during long-term operation, traditional pre-filter devices are prone to clogging of the filter due to the continuous accumulation of impurities in the water, which in turn causes increased water flow resistance and even causes the heat pump system to shut down due to insufficient water supply. In addition, cleaning of these filter devices often requires manual removal and cleaning of the filter after shutdown, which not only increases the maintenance workload but may also affect the continuous operation and overall efficiency of the heat pump system.

[0003] The existing Chinese patent publication number CN110420491B discloses a water inlet device that facilitates filter replacement.

A rotating block 609 is inserted into the inner wall of the mounting groove, and the other end of the rotating block 609 is fixedly connected to the mounting tube 610. A sliding groove is provided on the inner wall of the mounting tube 610, and a mounting ring 611 is slidably connected to the inner wall of the sliding groove. The outer wall of the mounting ring 611 is fixedly connected to the outer wall of the filter screen 612, and the inner wall of the sliding groove provided on the mounting tube 610 contacts the outer wall of the mounting ring 611, and the inner ring of the mounting ring 611 extends to the outside of the sliding groove and is connected to the filter screen 612. A power supply mechanism 613 is also provided on the upper part of the motor 606, and a trigger mechanism 614 is also provided inside the sliding groove provided on the mounting tube 610;

[0030] The power supply mechanism 613 includes a trigger mechanism 614, which includes a DC electromagnet 401. The outer wall of the DC electromagnet 401 is fixedly connected to the side of the inner wall of the chute away from the mounting ring 611. A magnet ring 402 is provided on the upper side of the DC electromagnet 401. The outer wall of the magnet ring 402 contacts the inner wall of the chute. The side of the magnet ring 402 away from the DC electromagnet 401 is fixedly connected to the first spring 404. The other end of the first spring 404 is fixedly connected to the outer wall of the mounting ring 611. The outer wall of the mounting ring 611 away from the magnet ring 402 is also fixedly connected to a conductive sheet 405. One side of the conductive sheet 405 extends to the lower side of the mounting ring 611. The outer wall of the magnet ring 402 is fixedly connected to the third conductive contact 403. A circular hole is formed on the outer side of the mounting tube 610 away from the rotating rod 607. A second spring 408 is fixedly connected to the outer wall of the water inlet pipe 3 on the side away from the mounting tube 610. The other end of the second spring 408 is fixedly connected to the insertion rod 406. One end of the insertion rod 406 extends through the circular hole to the interior of the mounting tube 610, and a conductive rod 407 is fixedly connected to the inner wall of the insertion rod 406. Both ends of the conductive rod 407 are exposed to the outside of the insertion rod 406. The outer wall of the end of the insertion rod 406 located inside the mounting tube 610 is chamfered. Two conductive rods 407 are provided on the water inlet pipe 3. One end of the lower conductive rod 407 contacts the outer wall of the third conductive contact 403, and one end of the upper conductive rod 407 is located on the moving path of the conductive sheet 405.

[0031] During use, one end of the water supply pipe 5 is connected to the water pump, and water is transported through the water supply pipe 5 to the installation pipe 610 on the left and discharged downward. Impurities in the water are filtered and intercepted by the filter 612. The filtered water is discharged into the interior of the water bucket 1 through the water inlet pipe 3 for temporary storage, and then discharged to the water supply end of the heat pump through the exhaust pipe 2;

[0032] During use, one conductive rod 407 is electrically connected to the power supply, the other conductive rod 407 is electrically connected to the control module 7, and the other electrode of the control module 7 is electrically connected to the power supply. When water flows through the left mounting tube 610, the water is continuously filtered by the filter screen 612, which causes impurities to accumulate on the upper side of the filter screen 612, thereby reducing the amount of water passing through the filter screen 612 and increasing the thrust caused by the water flow impacting the filter screen 612. This causes the first spring 404 to be squeezed and contracted, causing the filter screen 612 to drive the mounting ring 611 downward relative to the mounting tube 610, causing the mounting ring 611 to drive the conductive sheet 405 downward to contact the upper side of the third conductive contact 403, and causing one end of the upper conductive rod 407 to contact the conductive sheet 405, thereby forming a path between the upper conductive rod 407, the conductive sheet 405, the third conductive contact 403, and the lower conductive rod 407, triggering the control module 7;

[0033] Then, the control module 7 turns off the water supply pump and starts the motor 606 to rotate the rotating rod 607 and the mounting pile 608 180 degrees, which in turn drives the two rotating blocks 609 and the mounting pipe 610 to rotate 180 degrees, so that the right mounting pipe 610 rotates to between the water inlet pipe 3 and the water supply pipe 5 on the left, so that the outer wall of the mounting pipe 610 contacts the outer wall of the water inlet pipe 3 and the water supply pipe 5 to form a channel, thereby continuing the water supply and filtration operation;

[0034] The power supply mechanism 613 includes a third bracket 301, the outer wall of the third bracket 301 is fixedly connected to the outer wall of the water inlet pipe 3, and the first gear ring 302 is fixedly connected to one side of the third bracket 301, and the first gear ring 302 is located on the lower side of the mounting pile 608. The outer wall of the rotating block 609 is fixedly connected to the second gear ring 303. Two fixing holes are provided on the side of the rotating block 609 close to the mounting pile 608. The inner walls of the two fixing holes are fixedly connected to the first conductive contacts 304. One end of the two first conductive contacts 304 is provided with a first wire 305. The two first conductive contacts 304 are respectively connected to the positive and negative poles of the DC electromagnet 401 through the first wire 305. Two second conductive contacts 306 are fixedly connected to the side of the mounting pile 608 close to the rotating block 609. The two first conductive contacts 304 are respectively connected to the positive and negative poles of the DC electromagnet 401 through the first wire 305. The two conductive contacts 306 are in contact with the two first conductive contacts 304 respectively, and the upper side of the outer wall of the rotating rod 607 is rotatably connected to the rotating rod 607 via a bearing. The two second conductive contacts 306 are electrically connected to the conductive slip ring 307 via a second wire 308. The upper right portion and rear portion of the first gear ring 302 are both provided with a toothed structure, and the outer wall of the second gear ring 303 is provided with a toothed structure. During the process of the second gear ring 303 revolving around the rotating rod 607, the toothed structure on its outer wall can engage with the toothed structure on the upper side of the first gear ring 302. The DC electromagnet 401 on the left side of the rotating rod 607 and the magnet ring 402 on the side close to each other have the same magnetic pole, and the DC electromagnet 401 on the right side of the rotating rod 607 and the magnet ring 402 on the side close to each other have opposite magnetic poles.

[0035] After the motor 606 is started, the mounting pile 608 drives the rotating block 609 to rotate. During the rotation, the second gear ring 303 engages with the first gear ring 302, causing the second gear ring 303 to drive the rotating block 609 to rotate 180 degrees. This causes the side of the filter 612 that intercepts impurities to rotate to the bottom side, causing impurities on the surface to fall off due to gravity. The cleaned filter 612, which is moving leftward on the right side, can be rotated 180 degrees to return to its original position due to the contact and rotation of the second gear ring 303 and the first gear ring 302.

[0036] When the mounting tube 610 is on the left side, the conductive slip ring 307 is connected to a power source, so that the conductive slip ring 307 supplies power to the DC electromagnet 401 via the second wire 308, the second conductive contact 306, the first conductive contact 304, and the first wire 305. This aligns the magnetic poles of the upper side of the DC electromagnet 401 with the lower side of the magnet ring 402, thereby causing the magnet ring 402 to float above the DC electromagnet 401. The filter screen 612 and the mounting ring 611, supported by the elastic force of the first spring 404 and the magnet ring 402 and the DC electromagnet 401, can be cushioned against the impact of the water flow when filtering impurities in the water, thereby preventing impurities in the water from being stuck on the filter screen 612 due to excessive impact force when impacting the upper side of the filter screen 612.

[0037] When the mounting tube 610 moves to the right, the rotating block 609 is driven by the second gear ring 303 to deflect 180 degrees, and the contact position of the two first conductive contacts 304 and the two second conductive contacts 306 changes, thereby reversing the magnetic pole of the DC electromagnet 401, causing the DC electromagnet 401 to upwardly absorb the magnet ring 402 from which impurities have fallen, causing the magnet ring 402 to move upward rapidly and produce an impact, thereby causing the filter 612 to vibrate, loosening impurities stuck on its surface. At this time, the fan 601 exhausts air through the air pipe 602 and the exhaust box 603, which can further blow impurities on the filter 612 downward, thereby completing the removal of impurities and drying the filter 612, slowing down the rusting rate of the filter 612, and increasing its service life.
