Description

Technical Field

[0001] The present invention relates to the technical field of filters, and more particularly to a multi-channel parallel integrated filter for a refrigeration system. Background Art

[0002] Air conditioning is an air conditioner. It refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. In the refrigeration system, filters are indispensable. Filters can extend the service life of the equipment and reduce equipment maintenance.

[0003] When the existing air-conditioning coolant filter filters the filter screen, particles will appear in some of the coolant. When the particles on the filter screen accumulate to a certain value, the filtering effect of the coolant will deteriorate, resulting in the need for personnel to clean the filter screen later. However, the filters used in existing refrigeration systems are mostly integral structures and cannot be disassembled to clean the filter screen inside. After the filter has been used for a period of time, the filter needs to be replaced as a whole, and the filter is not damaged, which will cause waste of materials. In addition, when the coolant flow rate is too fast, the coolant will impact the filter screen, resulting in poor filtering effect. When the liquid level in the filter drops to a certain value, the existing filter cannot prompt personnel to add coolant. Summary of the invention

[0039] In a specific embodiment of the present invention, there are two groups of limit plates 13 and metal filters 14. The diameter of one group of metal filters 14 near the buffer component 16 is larger than the diameter of the other group of metal filters 14. The internal connecting pipe 3 near the buffer component 16 is set as a coolant inlet pipe, and the internal connecting pipe 3 near the rotor flowmeter 22 is set as a coolant outlet pipe. The buffer component 16 reduces the impact of the coolant on the metal filter 14, the isolation component 15 isolates the metal filter 14, and the cleaning component 12 cleans the metal filter 14. The impurities after cleaning flow into the filter box 8 with the coolant. The amount of coolant in the filter housing 1 is detected by the liquid level meter 23. When the coolant is less, the alarm light 7 sends a signal to remind people to add coolant. The protective housing 6 is provided with heat dissipation holes 10 to dissipate heat for the controller 11 and the motor 1201 to ensure the stable operation of the equipment.

[0040] Specifically, the cleaning component 12 includes a motor 1201, a driving pulley 1202, a driven pulley 1203, a belt 1204, a first positioning rod 1205, a screw rod 1206 and a sliding seat 1207. The motor 1201 is symmetrically arranged on one side of the filter housing 1, and the output shaft end of the motor 1201 is fixedly connected to the driving pulley 1202. The first positioning rod 1205 is symmetrically arranged inside the filter housing 1, and the screw rod 1206 is rotatably connected inside the filter housing 1. A sliding seat 1207 matching the screw rod 1206 is slidably connected to the first positioning rod 1205, and one end of the screw rod 1206 is fixedly connected to the driven pulley 1203, and the driven pulley 1203 and the driving pulley 1202 are connected through a belt 1204.

[0041] In a specific embodiment of the present invention, the motor 1201 is started to drive the driving pulley 1202 to rotate, and the rotation of the driving pulley 1202 drives the driven pulley 1203 to rotate, and the rotation of the driven pulley 1203 drives the screw rod 1206 to rotate, thereby controlling the sliding seat 1207 to move along the first positioning rod 1205, and the reciprocating movement of the sliding seat 1207 along the first positioning rod 1205 is controlled by the forward and reverse rotation of the motor 1201.

[0042] Specifically, the cleaning assembly 12 also includes a second positioning rod 1208, a sliding rod 1209, a first spring 1210 and a cleaning plate 1211. The second positioning rod 1208 is arranged at a central position on one side of the sliding seat 1207. One end of the second positioning rod 1208 is slidably connected to the sliding rod 1209. One end of the sliding rod 1209 is fixedly connected to the cleaning plate 1211. A first spring 1210 matching the first spring 1210 is arranged between the cleaning plate 1211 and the second positioning rod 1208. The surface of the cleaning plate 1211 is provided with bristles matching the cleaning plate 1211.

[0043] In a specific embodiment of the present invention, the cleaning plate 1211 maintains contact with the metal filter 14 under the action of the sliding rod 1209, so that the metal filter 14 can be better cleaned by the bristles, and the second positioning rod 1208 and the sliding rod 1209 cooperate with each other to ensure the vertical force between the cleaning plate 1211 and the metal filter 14, thereby preventing the cleaning plate 1211 from having poor cleaning effect at certain angles due to uneven force.

[0044] Specifically, the isolation component 15 includes an air pump 1501, an air pipe 1502, a pressure gauge 1503, a positioning plate 1504 and an inflatable cushion 1505. The air pump 1501 is arranged on the side of the filter housing 1 close to the controller 11. The air pipe 1502 is fixedly connected to the air pump 1501, and the air pipe 1502 is equidistantly arrayed with the pressure gauge 1503. A positioning plate 1504 is arranged inside the filter housing 1, and an inflatable cushion 1505 is arranged inside the positioning plate 1504. The inflatable cushion 1505 is fixedly connected to the air pipe 1502, the positioning plate 1504 is matched with the inflatable cushion 1505, the inflatable cushion 1505 is matched with the limiting plate 13, and the inflatable cushion 1505 is matched with the filter housing 1.

[0045] In a specific embodiment of the present invention, the air pump 1501 is started, and the inflatable cushion 1505 is inflated through the air pipe 1502. The inflatable cushion 1505 expands in the positioning plate 1504. The coolant is isolated by the inflatable cushion 1505 to avoid impurities contaminating other coolants when cleaning the metal filter 14, thereby reducing the loss of coolant. The pressure of the inflatable cushion 1505 can be monitored by the barometer 1503 to avoid insufficient pressure in the inflatable cushion 1505, which results in poor coolant isolation effect.

[0046] Specifically, the buffer assembly 16 includes a limit rod 1601, a limit block 1602, a second spring 1603, a sliding block 1604 and a buffer cover 1605.

[0047] In a specific embodiment of the present invention, the coolant flowing into the filter housing 1 generates an impact force on the buffer cover 1605 , and the buffer cover 1605 buffers the impact force under the action of the second spring 1603 to prevent the impact force from affecting the filtering effect of the metal filter 14 .

[0048] Specifically, the water filter assembly 19 includes a positioning frame 1901, a positioning groove 1902, a placement box 1903 and a connecting groove 1904.

[0049] In a specific embodiment of the present invention, the desiccant absorbs the water in the refrigerant and absorbs the excess water and acidic substances in the refrigeration system, thereby ensuring that the system operates in an optimal state. The diameter of the desiccant is larger than the connecting groove 1904, ensuring the flow of the coolant and limiting the flow of the desiccant, so that the desiccant is stable in the placement box 1903.

[0050] Specifically, the slag removal component 20 includes a filtrate hole 2001, a connecting box 2002 and a solenoid valve 2003.

[0051] In a specific embodiment of the present invention, after cleaning is completed, the solenoid valve 2003 is opened, and impurities flow into the filter box 8 along with the refrigerant. After the refrigerant flows into the filter box 8, the solenoid valve 2003 is closed to ensure that the impurities remain in the filter box 8, thereby ensuring the purity of the refrigerant in the filter housing 1.

[0052] Specifically, a mounting frame 21 is symmetrically arranged inside the filter housing 1, a rotor flowmeter 22 is arranged on the mounting frame 21, the rotor flowmeter 22 is matched with the connecting port 17, a liquid level meter 23 is arranged inside the filter housing 1, the rotor flowmeter 22 and the liquid level meter 23 are both electrically connected to the controller 11, and the mounting frame 21 is arranged on the side of the filter housing 1 away from the buffer assembly 16.

[0053] In a specific embodiment of the present invention, the flow rate of the coolant flowing back to the refrigeration system is detected by the rotor flowmeter 22. When the metal filter 14 is blocked, the flow rate of the refrigerant slows down, and the rotor flowmeter 22 sends a signal to the controller 11. The controller 11 controls the slag discharge pipe 9 to start, promptly reminding people that the metal filter 14 is blocked, and promptly shutting down the refrigeration system for self-cleaning.

The second connecting block 1806 is matched with the first connecting block 1802, and the first connecting seat 1801 is matched with the second connecting seat 1805.

[0056] Working principle: the external connecting pipe 4 is fixedly connected with the coolant infusion pipe of the refrigeration system, and the external connecting pipe 4 is fixedly connected with the internal connecting pipe 3 through the connecting component 18. The coolant flows into the filter housing 1 from the connecting port 17 on the side close to the buffer component 16. The coolant is buffered by the buffer component 16 to avoid excessive coolant flow rate affecting the filtering effect. The coolant flowing into the filter housing 1 is filtered through the metal filter mesh 14 and then returns to the refrigeration system through the internal connecting pipe 3. When the rotor flowmeter 22 detects that the refrigerant flowing back to the refrigeration system is reduced, the refrigeration system is turned off, the isolation component 15 is started, the air pump 1501 inflates the inflatable cushion 1505, and the metal filter 14 is isolated between the inflatable cushion 1505 and the inflatable cushion 1505, the cleaning component 12 is started, the cleaning plate 1211 reciprocates along the second positioning rod 1208, and the impurities on the surface of the metal filter 14 are cleaned by the bristles on the cleaning plate 1211. After the cleaning is completed, the solenoid valve 2003 is opened, and the refrigerant between the inflatable cushion 1505 and the inflatable cushion 1505 carries impurities and flows into the filter box 8. After the coolant flows into the filter box 8, the solenoid valve 2003 is closed, the gas in the inflatable cushion 1505 is discharged, and the refrigeration system is started by inflating. When the coolant in the filter box 8 is full, the refrigerant with impurities is discharged through the slag discharge pipe 9.
