[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the refrigeration unit is working, the electrostatic field generated by the ion rod will continuously purify the refrigerant in the shell, so that the refrigerant discharged through the second connecting pipe is clean, thereby achieving water purification and preventing scale and impurities from adhering to the equipment inside the shell, thereby improving the use efficiency of the refrigeration unit.

[0032] See also Figure 1-Figure 11 The present invention provides a technical solution: a high-voltage electrostatic brine purification device for a refrigerating unit, comprising a shell 1, a first connecting pipe 2 and a second connecting pipe 3 are fixedly connected to the middle of the left and right sides of the shell, respectively, an ion rod 4 is fixedly connected to the shell 1, the bottom of the shell 1 is conical, the rod of the ion rod 4 extends to the inside of the shell 1, a filter frame 5 is arranged inside the shell 1, the ion rod 4 is located inside the filter frame 5, a sewage outlet 6 is opened below the shell 1, a sewage outlet group is arranged above the sewage outlet 6, and the sewage outlet group is used to discharge impurities precipitated inside the shell 1.

[0033] When the above scheme is put into actual use, the first connecting pipe 2 and the second connecting pipe 3 are connected to the refrigerating unit. Since the refrigerant, i.e., the refrigerant, circulates when the refrigerating unit is working, the refrigerant flows from the first connecting pipe 2 to the inside of the second connecting pipe 3. Since the inside of the shell 1 is filled with the refrigerant, the refrigerant flows from the first connecting pipe 2 into the inside of the shell 1 and then flows out from the inside of the second connecting pipe 3, thereby circulating.

[0034] When the refrigerant flows from the first connecting pipe 2 into the second connecting pipe 3, the refrigerant will first contact the filter frame 5, and the rust impurities in the refrigerant can be filtered through the filter frame 5. The filtered impurities will adhere to the filter frame 5 or settle under the shell 1. When the refrigeration unit is working, the ion rod 4 is energized. After the ion rod 4 is energized, the rod alloy of the ion rod 4 in the refrigerant inside the shell 1 will produce a high-voltage electrostatic field around the probe to maintain continuous treatment of water, surround the cations and anions in the water, prevent them from chemically reacting, and generate a high-voltage electrostatic field around the water molecules. The potential difference is formed between the device and the device, and the ability of bound ions to gather toward the device is used to prevent scaling. In the high-voltage electrostatic field, the electronic binding ability between scale molecules is destroyed, and its crystal structure is changed, which makes it loose and causes the scale to gradually fall off. Under the action of the electric field, the impurities in the refrigerant inside the shell 1 are continuously decomposed and precipitated. The precipitated impurities will fall into the drain port 6, and the impurities and rust blocked by the filter frame 5 will also fall into the drain port 6, so that the refrigerant passing through the second connecting pipe 3 is clean, thereby achieving water purification and improving the use efficiency of the refrigeration unit;

[0035] When the refrigeration unit is working, the electrostatic field generated by the ion rod 4 will continuously purify the refrigerant in the shell 1, so that the refrigerant discharged through the second connecting pipe 3 is clean, thereby achieving water purification and improving the utilization efficiency of the refrigeration unit. The impurities precipitated in the sewage outlet 6 can also be discharged to the outside under the action of the sewage discharge group.

[0036] As a further solution of the present invention, the sewage discharge group includes a first seal 7 and a second seal 8, the second seal 8 is slidably connected inside the sewage discharge port 6, the first seal 7 is located above the sewage discharge port 6, and the sewage discharge group also includes a driving group, which is used to drive the first seal 7 and the second seal 8 to descend linearly.

[0037] When the sewage discharge group is working, when it is necessary to discharge the impurities inside the shell 1, the driving group is started. When the driving group is working, it will drive the first seal 7 and the second seal 8 to descend. The first seal 7 is normally located above the sewage outlet 6, and the bottom of the shell 1 is conical, which can facilitate the impurities to fall directly onto the second seal 8 in the sewage outlet 6. When the driving group is working, the first seal 7 descends to the top of the sewage outlet 6. At this time, the first seal 7 will contact the inner wall of the shell 1 and close the sewage outlet 6. At this time, there is a certain distance between the first seal 7 and the second seal 8. , and then the driving group drives the second seal 8 to slide and descend inside the sewage outlet 6. The top of the second seal 8 is the precipitation position of the impurities. The driving group will drive the second seal 8 to descend to the bottom of the shell 1, that is, the second seal 8 will be separated from the sewage outlet 6, and then the impurities and a small amount of refrigerant will directly flow out from the bottom of the shell 1, thereby discharging the impurities. A small amount of refrigerant can also flush the impurities along with the impurities, thereby facilitating the separation of all the impurities from the second seal 8, and then the driving group drives the second seal 8 to enter the sewage outlet 6, and then the first seal 7 and the second seal 8 are reset to their initial positions.

[0038] As a further solution of the present invention, the drive group includes two motors 9, a ring gear 11 and a reciprocating screw rod 12, the two motors 9 are both located inside the housing 1, the output shafts at the tops of the two motors 9 are both fixedly connected with gears 10, the ring gear 11 is fixedly connected to the top of the filter frame 5, the filter frame 5 is rotatably connected to the housing 1, the two gears 10 are meshed with the ring gear 11 together, the reciprocating screw rod 12 is fixedly connected to the bottom of the filter frame 5, the reciprocating screw rod 12 is threadedly connected with a connecting piece 13, the connecting piece 13 is fixedly connected with two limit rods 14, the two limit rods 14 are slidably connected with a sleeve rod 15 on the outside, the sleeve rod 15 is fixedly connected to the inner wall of the housing 1, and the two limit rods 14 are slidably connected to the first sealing member 7;

[0039] A first spring 32 is fixedly connected between the two limit rods 14 and the first seal 7. The first seal 7 is slidably connected to two vertical rods 16. The two vertical rods 16 are fixedly connected to the second seal 8. A second spring 17 is fixedly connected between the two vertical rods 16 and the first seal 7.

[0040] When the driving group is working and discharging sewage, the motor 9 is started first, and the motor 9 drives the gear 10 to rotate when working. When the gear 10 rotates, it drives the filter frame 5 and the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, the connecting piece 13 and the limit rod 14 are lowered. When the limit rod 14 is lowered, the sleeve rod 15 limits the limit rod 14, so that the limit rod 14 is lowered normally.

[0041] When the limiting rod 14 descends, it will drive the first sealing member 7 to descend. When the first sealing member 7 descends to contact the inner wall of the shell 1, it will be blocked by the shell 1 and cannot descend. At this time, the first sealing member 7 will close the sewage outlet 6, and then the reciprocating screw rod 12 continues to drive the limiting rod 14 to descend. When the limiting rod 14 descends at this time, it will slide downward along the first sealing member 7 and stretch the first spring 32. As the limiting rod 14 descends, the first spring 32 will also be gradually stretched. When the bottom end of the limiting rod 14 contacts the second sealing member 8, the limiting rod 14 will push the second sealing member 8 to descend inside the sewage outlet 6. When the second sealing member 8 descends, it will drive the vertical rod 16 to slide and descend along the first sealing member 7 and stretch the second spring 17, so that the second sealing member 8 descends vertically. When the reciprocating screw rod 12 drives the connecting member 13 and the limiting rod 14 to descend to the limit position, the second sealing member 8 has also moved to the bottom of the shell 1. At this time, the impurities above the second sealing member 8 also flow out to the outside, thereby realizing the sewage discharge of the impurities.

[0042] Then the reciprocating screw 12 drives the connecting piece 13 and the limiting rod 14 to rise. At this time, the second sealing piece 8 will also rise along with the limiting rod 14 under the action of the second spring 17, and the elasticity of the first spring 32 of the first sealing piece 7 will gradually be released when the limiting rod 14 rises. When the second sealing piece 8 moves to the initial position, the elasticity of the second spring 17 has been released, and then the limiting rod 14 will drive the first sealing piece 7 to rise to the initial position.

[0043] As a further solution of the present invention, a round rod 18 is fixedly connected to the bottom end of the reciprocating screw rod 12, and the round rod 18 passes through the first seal 7 and is rotatably connected to the first seal 7. A stirring blade 19 is arranged below the round rod 18, and the stirring blade 19 is rotatably connected to the second seal 8. Two connecting rods 20 are fixedly connected to the stirring blade 19, and a pressing plate 21 is slidably connected inside the two connecting rods 20. A third spring 22 is fixedly connected between the two pressing plates 21 and the two connecting rods 20, and the pressing plate 21 is used to press the round rod 18 down.

[0044] When the above scheme is working, when the limiting rod 14 drives the first sealing member 7 to descend to the position in contact with the inner wall of the shell 1, the first sealing member 7 will seal the sewage outlet 6, and then the limiting rod 14 will continue to descend until the limiting rod 14 contacts the second sealing member 8. The limiting rod 14 will push the second sealing member 8 to slide down. When the second sealing member 8 slides down, the stirring blade 19 will also follow the second sealing member 8 to descend. The height position of the round rod 18 is fixed, and the pressing piece 21 is above the bottom end of the round rod 18. Therefore, when the second sealing member 8 and the stirring blade 19 descend, the connecting rod 20 will also descend. When the connecting rod 20 descends, the pressing piece 21 will contact the bottom end of the round rod 18 and gradually compress the third spring 22 when the connecting rod 20 descends. At this time, the downward pressure and friction force of the pressing piece 21 on the round rod 18 gradually increase. Then the rotation of the reciprocating screw 12 and the round rod 18 will cause the pressing sheet 21 to drive the connecting rod 20 and the stirring blade 19 to rotate, so that when the second seal 8 is not separated from the drain outlet 6, the impurities above the second seal 8 and a small amount of refrigerant will be stirred, so that the precipitated impurities are mixed with the refrigerant, and then directly discharged to the outside when the second seal 8 is separated from the drain outlet 6, so that the impurities can be discharged quickly and cleanly;

[0045] Then the reciprocating screw 12 drives the limiting rod 14 to rise, and the second sealing member 8, the stirring blade 19 and the pressing piece 21 are reset accordingly.

[0046] As a further solution of the present invention, two airbags 23 are arranged inside the shell 1, and the two airbags 23 are glued with limiting plates 24, and the two limiting plates 24 are slidably connected with U-shaped rods 25. A fluid infusion tube 26 is arranged above the two airbags 23, and the two fluid infusion tubes 26 pass through the shell 1. The two fluid infusion tubes 26 are commonly fixedly connected with a fluid infusion cylinder 27, and the fluid infusion cylinder 27 is fixedly connected to the outside of the shell 1, and the two airbags 23 are respectively fitted with the two fluid infusion tubes 26.

[0047] When the above scheme is working, a small amount of refrigerant will be discharged each time the sewage is discharged. Each time the impurities and refrigerant are discharged, the height of the refrigerant inside the shell 1 will drop to a certain extent. When the refrigerant liquid level drops, the air bag 23 floating above the refrigerant will drive the limit plate 24 to slide down along the U-shaped rod 25. At this time, a gap will appear between the refilling tube 26 and the top of the air bag 23, and the refrigerant liquid inside the refilling cylinder 27 will be replenished into the shell 1. After the air bag 23 floats to the degree of closing the tube mouth of the refilling tube 26 again, the refilling cylinder 27 will stop working, so that the refrigerant inside the shell 1 can be automatically replenished.

[0048] As a further solution of the present invention, two support columns 33 are fixedly connected to the inner wall of the shell 1, the two support columns 33 are located between the two airbags 23, the two support columns 33 are located outside the filter frame 5, and the two motors 9 are fixedly connected to the two support columns 33 respectively.

[0049] When the above scheme is working, the inner wall of the support column 33 is in contact with the filter frame 5. When the filter frame 5 rotates, the support column 33 can scrape away impurities on the surface of the filter frame 5 to a certain extent, and can also separate the refrigerant on both sides of the support column 33, so that the refrigerant with impurities is on the left and the clean refrigerant is on the right, which is convenient for the discharge of the second connecting pipe 3 and supports the motor 9.

[0050] As a further solution of the present invention, the filter frame 5 is fixedly connected with a contact block 28, the inner wall of the shell 1 is fixedly connected with a protrusion 29, and a telescopic block 30 is slidably connected inside the protrusion 29; the telescopic block 30 is fixedly connected with a fourth spring 31 for resetting it.

[0051] When the above scheme is working, the filter frame 5 rotates and drives the contact block 28 to rotate. When the contact block 28 rotates one circle, it will contact the telescopic block 30 and make the telescopic block 30 slide toward the inside of the protrusion 29 and compress the fourth spring 31. When the contact block 28 is separated from the telescopic block 30, the telescopic block 30 will knock on the filter frame 5 under the action of the fourth spring 31, so that the impurities outside the filter frame 5 can be quickly precipitated.

[0052] As a further solution of the present invention, the second sealing member 8 is conical.

[0053] When the above solution is working, the conical second sealing member 8 can facilitate the discharge of impurities.

[0054] Working principle: The first connecting pipe 2 and the second connecting pipe 3 are connected to the refrigerating unit. Since the refrigerant, i.e. the coolant, circulates when the refrigerating unit is working, the coolant flows from the first connecting pipe 2 to the inside of the second connecting pipe 3. The inside of the shell 1 is filled with the coolant, so the coolant flows from the first connecting pipe 2 into the inside of the shell 1 and then flows out from the inside of the second connecting pipe 3, thereby circulating;

[0055] When the refrigerant flows from the first connecting pipe 2 into the second connecting pipe 3, the refrigerant will first contact the filter frame 5, and the rust impurities in the refrigerant can be filtered through the filter frame 5. The filtered impurities will adhere to the filter frame 5 or settle under the shell 1. When the refrigeration unit is working, the ion rod 4 is energized. After the ion rod 4 is energized, the rod alloy of the ion rod 4 in the refrigerant inside the shell 1 will produce a high-voltage electrostatic field around the probe to maintain continuous treatment of water, surround the cations and anions in the water, prevent them from chemically reacting, and generate a high-voltage electrostatic field around the water molecules. The potential difference is formed between the device and the device, and the ability of bound ions to gather toward the device is used to prevent scaling. In the high-voltage electrostatic field, the electronic binding ability between scale molecules is destroyed, and its crystal structure is changed, which makes it loose and causes the scale to gradually fall off. Under the action of the electric field, the impurities in the refrigerant inside the shell 1 are continuously decomposed and precipitated. The precipitated impurities will fall into the drain port 6, and the impurities and rust blocked by the filter frame 5 will also fall into the drain port 6, so that the refrigerant passing through the second connecting pipe 3 is clean, thereby achieving water purification and improving the use efficiency of the refrigeration unit;

[0056] When the refrigeration unit is working, the electrostatic field generated by the ion rod 4 will continuously purify the refrigerant in the shell 1, so that the refrigerant discharged through the second connecting pipe 3 is clean, thereby achieving water purification and improving the utilization efficiency of the refrigeration unit. The impurities precipitated in the sewage outlet 6 can also be discharged to the outside under the action of the sewage discharge group.
