Description

Technical Field

[0002] The water source heat pump system uses water as a cold or hot source to provide cooling or heating for buildings through a heat exchange device. In order to ensure the efficient operation of the system, a pre-filter device is usually set at the water inlet end of the water source heat pump to intercept sediment, suspended matter and other impurities in the water body. However, during the long-term operation of the traditional pre-filter device, due to the continuous accumulation of impurities in the water body, it is easy to cause the filter screen to be blocked, thereby causing the water flow resistance to increase, and even causing the heat pump system to shut down due to insufficient water supply. In addition, the cleaning of these filter devices often requires manual removal and cleaning of the filter screen after shutdown, which not only increases the maintenance workload, but also may affect the continuous operation and overall efficiency of the heat pump system; The existing Chinese patent with publication number: CN110420491B discloses a water inlet device for facilitating filter replacement. The device can pull a handle to quickly take out the used filter, thereby realizing the rapid replacement of the filter.

A magnet ring 402 is arranged on the upper side of the DC electromagnet 401. The outer wall of the magnet ring 402 contacts the inner wall of the slide. A first spring 404 is fixedly connected to the side of the magnet ring 402 away from the DC electromagnet 401. The other end of the first spring 404 is fixedly connected to the outer wall of the mounting ring 611. A conductive sheet 405 is also fixedly connected to the side of the outer wall of the mounting ring 611 away from the magnet ring 402.

Impurities in the water are filtered and intercepted by the filter 612, and 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; When in 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 the water flows through the left installation tube 610, the water is continuously filtered by the filter screen 612, which will cause 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, thereby causing the first spring 404 to be squeezed and contracted, so that the filter screen 612 drives the mounting ring 611 to move downward relative to the installation tube 610, and the mounting ring 611 drives the conductive sheet 405 to move downward and contact the upper side of the third conductive contact 403, and one end of the upper conductive rod 407 contacts 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 to trigger the control module 7; Then the control module 7 turns off the water supply pump to deliver water, and then starts the motor 606 to drive the rotating rod 607 and the mounting pile 608 to rotate 180 degrees, and then drives the two rotating blocks 609 and the mounting pipe 610 to rotate 180 degrees, so that the mounting pipe 610 on the right is rotated to between the water inlet pipe 3 and the water delivery 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 delivery pipe 5 to form a channel, and then continues the water delivery and filtering operation; 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, a first gear ring 302 is fixedly connected to one side of the third bracket 301, the first gear ring 302 is located at 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 are 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, and 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 through a bearing, and the two second conductive contacts 306 are electrically connected to the conductive slip ring 307 through the second wire 308 respectively. The upper right part and the rear part of the first gear ring 302 are provided with a tooth structure, and the outer wall of the second gear ring 303 is provided with a tooth structure. During the process of the second gear ring 303 revolving around the rotating rod 607, the tooth structure of its outer wall can mesh with the tooth structure on the upper side of the first gear ring 302, and the DC electromagnet 401 located on the left side of the rotating rod 607 and the magnet ring 402 are close to each other. The side of the DC electromagnet 401 located on the right side of the rotating rod 607 and the magnet ring 402 are close to each other. The side is opposite. After the motor 606 is started, the mounting pile 608 drives the rotating block 609 to rotate. During the rotation process, the second gear ring 303 meshes with the first gear ring 302, so that the second gear ring 303 drives the rotating block 609 to rotate 180 degrees, thereby causing the side of the filter screen 612 that intercepts impurities to rotate to the lower side, so that impurities on the surface fall off due to gravity, and the cleaned filter screen 612 moving from the right side to the left can be rotated 180 degrees to reset due to the contact and rotation of the second gear ring 303 and the first gear ring 302; When the installation tube 610 is located on the left side, the conductive slip ring 307 is connected to the power supply, so that the conductive slip ring 307 supplies power to the DC electromagnet 401 through the second wire 308, the second conductive contact 306, the first conductive contact 304, and the first wire 305, so that the upper side of the DC electromagnet 401 is consistent with the magnetic pole of the lower side of the magnet ring 402, and the magnet ring 402 is suspended on the upper side of the DC electromagnet 401. The filter screen 612 and the installation ring 611 can be elastically supported by the first spring 404 and the magnet ring 402 and the DC electromagnet 401. When filtering impurities in the water, they can be buffered against the impact of the water flow, so as to prevent the 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; When the mounting tube 610 moves to the right, since the rotating block 609 is driven by the second gear ring 303 to deflect 180 degrees, 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 absorb the magnet ring 402 on which impurities have fallen from the surface, causing the magnet ring 402 to move upward quickly to produce an impact, thereby causing the filter 612 to vibrate, loosening the impurities stuck on the surface, and at this time, the fan 601 exhausts air through the air pipe 602 and the exhaust box 603, which can further blow the 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 the service life.
