[0003] The existing chiller filtration system is usually designed to be more complicated, and the installation of the filter plate or filter screen often requires fixing with multiple screws or buckles. This design not only increases the difficulty of installation, but also requires operators to spend a lot of time and energy on disassembly and assembly when cleaning or replacing the filter plate, which not only affects the maintenance efficiency of the refrigeration system, but also increases the labor intensity of operators. Since the existing filter structure is cumbersome to disassemble and assemble, operators often need to use tools to pry and twist during the disassembly and assembly process. These operations may cause damage to the filter plate or filter screen if they are not careful. Once the filter structure is damaged, its filtering effect will be greatly reduced, and may even cause the performance of the entire refrigeration system to decline. Summary of the invention

[0006] Preferably, a water tank is fixedly installed at the bottom of the filter box, and an input end of one side of the water pump is connected to a water suction pipe, and one side of the water suction pipe passes through the interior of the water tank.

[0012] A method for using a water chiller with a high-efficiency filtering function comprises the following steps:

[0013] Step 1. First, after the chiller is started, the refrigerant evaporates in the evaporator and absorbs heat, thereby lowering the water temperature around the evaporator. The evaporated low-temperature and low-pressure refrigerant vapor is sucked into the compressor and compressed into high-temperature and high-pressure refrigerant vapor. The high-temperature and high-pressure refrigerant vapor enters the condenser and condenses into high-pressure liquid refrigerant. The liquid refrigerant condensed in the condenser flows into the filter box.

[0014] Step 2: In the filter box, the liquid refrigerant passes through three filter plates in turn. Each filter plate is equipped with filter screen 1, filter screen 2 and filter screen 3 to remove impurities and particulate matter. The filtered liquid refrigerant flows into the water tank for storage. The water pump is started to extract the filtered liquid refrigerant from the water tank through the suction pipe. The extracted liquid refrigerant is throttled and reduced in pressure by the expansion valve to become a low-temperature and low-pressure liquid or a gas-liquid mixture. The low-temperature and low-pressure liquid or gas-liquid mixture enters the evaporator, evaporates again, absorbs heat, and completes the refrigeration cycle.

[0015] Step three, during the installation or maintenance process, the filter plate is fixed to the side seat through the card slot, and the push rod is driven by the electric telescopic rod to drive the fixing block to be inserted into or disengaged from the fixing slot, thereby achieving a stable installation of the filter plate. The cooperation between the arc-shaped limit block and the arc-shaped limit slot, as well as the elastic force of the return spring, further ensure the stability of the filter plate on the mounting plate.

[0016] Step 4: Sealing gasket 1 and sealing gasket 2 respectively ensure the sealing between the filter plate and the positioning frame and the mounting plate to prevent refrigerant leakage. When the filter plate needs to be replaced or cleaned, the operator can pull the pull plate to drive the external plate and the three filter plates to move together for easy disassembly and installation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The chiller with high-efficiency filtering function adopts a design that cooperates with the card slot and the side seat, so that the filter plate can be easily inserted and fixed without the use of complex fixings such as screws or buckles, which greatly simplifies the disassembly and assembly process. The push rod is driven by the electric telescopic rod to drive the fixing block to be inserted into or disengaged from the fixing slot, so that the filter plate can be quickly and firmly installed and removed, which reduces the workload of operators and improves maintenance efficiency. The flexible driving method of the electric telescopic rod avoids damage to the filter plate or filter screen caused by prying, twisting and other operations during traditional disassembly and assembly, and protects the integrity of the filter structure. The anti-slip pad on the fixing block increases the friction with the fixing slot, further ensuring the stability of the filter plate during installation and reducing the risk of damage caused by shaking or misalignment. The sealing gasket 2 ensures the sealing between the filter plate and the side seat and the mounting plate respectively, effectively preventing the leakage of refrigerant during the filtering process, and ensuring the safe and stable operation of the refrigeration system. The coordinated design of the arc limit block and the arc limit groove, as well as the elastic force of the return spring, jointly ensure the stability of the filter plate on the mounting plate, and avoid the loosening or displacement of the filter plate caused by vibration or impact, thereby ensuring the continuous stability of the filtering effect. By pulling the pull plate, the operator can easily drive the external plate and the three filter plates to move together, realizing the rapid disassembly and replacement of the filter plate, facilitating cleaning and maintenance, and reducing maintenance costs. The overall structural design of the present invention is reasonable, and the coordination of the slide groove, the support rod and the slider ensures the stable sliding of the movable plate 1, thereby improving the overall reliability and stability of the system.

The extracted liquid refrigerant passes through the expansion valve (7) to throttle and reduce the pressure, and becomes a low-temperature and low-pressure liquid or a gas-liquid mixture. The low-temperature and low-pressure liquid or gas-liquid mixture enters the evaporator (2), evaporates again, absorbs heat, and completes the refrigeration cycle. Step 3: During installation or maintenance, the filter plate (11) is fixed to the side seat (9) via the clamping groove (19), and the push rod (25) is driven by the electric telescopic rod (24) to drive the fixing block (27) to be clamped into or out of the fixing groove (21), thereby achieving a stable installation of the filter plate. The coordination between the arc-shaped limiting block (37) and the arc-shaped limiting groove (40), as well as the elastic force of the return spring (38), further ensure the stability of the filter plate on the mounting plate (17); Step 4, sealing gasket 1 (34) and sealing gasket 2 (39) respectively ensure the sealing between the filter plate and the positioning frame (20) and the mounting plate (17) to prevent refrigerant leakage. When the filter plate needs to be replaced or cleaned, the operator can pull the pull plate (16) to drive the external plate (15) and the three filter plates (11) to move together, which is convenient for disassembly and installation.
