Description

Technical Field

[0001] This utility model belongs to the field of antifreeze purification technology, specifically relating to a multi-gradient antifreeze purification device. Background Technology

[0002] In the cooling system of a gas generator set, antifreeze is distributed through pipes to cover high-temperature areas such as the engine block water jacket, cylinder liner, and cylinder head water jacket, maintaining the engine within its optimal operating temperature range of 85-95°C. Because antifreeze contains corrosion inhibitors, anti-boiling agents, and antifreeze components, it effectively prevents the cooling system from freezing in low-temperature environments and boiling under high-temperature conditions, playing a crucial role in ensuring the long-term reliable operation of the cooling system.

[0003] During actual operation and maintenance of the unit, prolonged high-temperature operation can cause the rust layer on the inner wall of the cooling pipes to peel off, producing metal oxide particles that enter the antifreeze. Additionally, during equipment maintenance, dust, metal shavings, and other impurities may be introduced into the antifreeze. Furthermore, minor cylinder head gasket failure or poor oil cooler sealing can cause a small amount of engine oil to seep into the antifreeze. The accumulation of these impurities reduces the thermal conductivity of the antifreeze, and oily substances can form a thermally resistive layer on the heat exchanger surface. In severe cases, this can lead to localized blockage of the cooling system, affecting the unit's operational stability.

[0004] Currently, antifreeze purification mainly employs two methods: one is to periodically replace the entire tank of antifreeze. However, this method requires draining all the old fluid and adding new fluid, which not only wastes antifreeze resources but also disrupts the pressure balance of the cooling system due to frequent replacements, increasing the risk of cavitation. The second method involves connecting a simple screen filter in series in the circuit. While this can remove particulate impurities, it lacks effective separation capabilities for emulsified engine oil and cannot solve the problems of thermal resistance and reduced corrosion inhibition caused by oily contaminants. Therefore, there is an urgent need to design a highly efficient purification device that can simultaneously remove particulate impurities, metal oxides, and oily contaminants to achieve antifreeze recycling and maintain the optimal operating condition of the cooling system. Utility Model Content

[0005] To address the problem of impurities in antifreeze in the prior art, this invention provides a multi-gradient antifreeze purification device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-gradient antifreeze purification device, comprising a workbench welded from square tubes, a purification tank and a vertical motor installed on the workbench, a centrifuge tank installed inside the purification tank, a perforated grid installed on the purification tank, an oleophilic film tightly attached to the surface of the perforated grid, a collection trough installed on the outer side wall of the purification tank, and the vertical motor driving the centrifuge tank to rotate to achieve antifreeze purification and separation by centrifugal force.

[0007] As a further supplement to the above technical solution, a stepped surface is provided on the outer side wall of the purification bucket, and the collection trough is engaged with the purification bucket through the stepped surface and is in close contact with the outer wall of the purification bucket.

[0008] As a further supplement to the above technical solution, handles are symmetrically provided on the outer wall of the collection tank, which facilitates maintenance personnel to remove the collection tank from the purification tank.

[0009] As a further explanation of the above technical solution, an oil nozzle is provided on the collection tank, which facilitates the discharge of the collected engine oil.

[0010] As a further supplement to the above technical solution, a cover plate is provided on the collection tank, and a sealing plug is provided on the cover plate to prevent splashing during the antifreeze purification process.

[0011] As a further supplement to the above technical solution, fasteners are provided on both sides of the oleophilic membrane, and matching grooves are opened on the purification tank. The oleophilic membrane is inserted into the grooves by two fasteners, so that the oleophilic membrane is stretched and adhered to the surface of the hollow grid.

[0012] As a further supplement to the above technical solution, a conical surface is provided on the inner wall of the centrifuge tank, and a retention ring is provided on the conical surface. The retention ring is used to retain rust at the bottom of the centrifuge tank during the antifreeze purification process.

[0013] As a further supplement to the above technical solution, a rotating plate is provided inside the purification tank, and the output shaft of the vertical motor is connected to the rotating shaft of the rotating plate through a pulley transmission mechanism. The centrifuge tank is mounted on the rotating plate.

[0014] As a further explanation and limitation of the above technical solution, a lifting lug is provided on the centrifuge tank, which facilitates maintenance personnel to remove the centrifuge tank from the purification tank after purification and separation.

[0015] As a further explanation and limitation of the above technical solution, a plug is fixed at the center of the rotating plate, and a corresponding insertion hole is provided at the bottom of the centrifuge barrel.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention achieves effective separation of impurities such as engine oil and rust from antifreeze through the synergistic action of the centrifuge tank, the oleophilic membrane, and the retention ring. Engine oil rises to the surface of the antifreeze under centrifugal force and then passes through the oleophilic membrane into the collection tank, while rust sinks to the bottom of the centrifuge tank under centrifugal force. When pouring the antifreeze, the angle formed by the retention ring and the conical surface effectively prevents rust from flowing out with the antifreeze, thereby improving the purification efficiency and quality of the antifreeze.

[0018] 2. This utility model adopts a split collection tank design, allowing the collection tank to rest against the outer wall of the purification tank on the stepped surface. Meanwhile, the handle design makes it easier to separate the collection tank after purification, facilitating operation by maintenance personnel, and the oil nozzle design makes it convenient to pour out the engine oil.

[0019] 3. By setting fasteners at both ends of the oleophilic membrane, this utility model enables the oleophilic membrane to be tightly attached to the surface of the perforated grid, avoiding gaps between the oleophilic membrane and the perforated grid during operation, thus ensuring that the oil can smoothly pass through the oleophilic membrane and fall into the collection tank.

Detailed Implementation

[0025] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 4 The present invention will be further described in detail through three embodiments. Example 1

[0026] This embodiment provides a multi-gradient antifreeze purification device, as shown in the attached diagram. Figures 1 to 3As shown, the device is a multi-gradient antifreeze purification device, including a workbench 1 welded from square tubes, a purification tank 2 and a vertical motor 3 installed on the workbench 1, a centrifuge tank 4 inside the purification tank 2, a perforated grid 5 on the purification tank 2, an oleophilic film 6 tightly attached to the surface of the perforated grid 5, and a collection tank 7 installed on the outer side wall of the purification tank 2. The vertical motor 3 drives the centrifuge tank 4 to rotate and uses centrifugal force to achieve antifreeze purification and separation.

[0027] It should be noted that the oleophilic film 6 is existing technology. Its purpose is to block the antifreeze inside the centrifuge tank 4, while allowing oily substances such as engine oil to pass through. No further details will be provided.

[0028] Furthermore, we provide a conical surface 401 on the inner wall of the centrifuge tank 4, and a trapping ring 402 on the conical surface 401. The trapping ring 402 is used to trap rust at the bottom of the centrifuge tank 4 during the antifreeze purification process.

[0029] Meanwhile, a rotating plate 10 is installed inside the purification tank 2. The output shaft of the vertical motor 3 is connected to the rotating shaft of the rotating plate 10 through a pulley transmission mechanism. The centrifuge tank 4 is installed on the rotating plate 10. A lifting lug 403 is provided on the centrifuge tank 4, which facilitates maintenance personnel to remove the centrifuge tank 4 from the purification tank 2 after purification and separation.

[0030] In this design, we fix a plug 1001 at the center of the rotating plate 10, and provide a corresponding socket 404 at the bottom of the centrifuge tank 4. The centrifuge tank 4 is stably connected to the rotating plate 10 through the plug 1001 and the socket 404. Example 2

[0031] Based on Example 1, to facilitate the removal of the collection tank 7 from the purification tank 2 and the cleaning of the engine oil, as shown in the attached... Figure 2 and attached Figure 3 As shown, a stepped surface 201 is provided on the outer side wall of the purification tank 2, and the collection tank 7 is engaged with the purification tank 2 via the stepped surface 201 and is tightly attached to the outer wall of the purification tank 2. Handles 701 are symmetrically provided on the outer wall of the collection tank 7 to facilitate the removal of the collection tank 7 from the purification tank 2 by maintenance personnel. An oil nozzle 702 is provided on the collection tank 7 to facilitate the drainage of collected engine oil. A cover plate 8 is fitted over the collection tank 7, and a sealing plug 801 is provided on the cover plate 8 to prevent splashing during the antifreeze purification process. Example 3

[0032] Based on Examples 1 and 2, in order to ensure that the oleophilic film 6 and the perforated grid 6 are tightly bonded, as shown in the attached... Figure 4As shown, we have fasteners 9 on both sides of the oleophilic membrane 6 and matching grooves 202 on the purification tank 2. The oleophilic membrane 6 is inserted into the grooves 202 by the two fasteners 9, so that the oleophilic membrane 6 is stretched and attached to the surface of the hollow grid 5.

[0033] Its working principle:

[0034] The maintenance personnel place the centrifuge tank 4, filled with antifreeze, into the purification tank 2 through the lifting lug 403. The centrifuge tank 4 is then inserted into the rotating plate 10 via the insertion hole 404 and the plug 1001. The cover plate 8 is then placed on the collection tank 7. The vertical motor 3 is started, driving the rotating plate 10 to rotate via a pulley drive. As the centrifuge tank 4 rotates with the rotating plate 10, centrifugal force is generated, causing the engine oil to rise to the surface of the antifreeze and pass through the oleophilic film 6, being thrown out of the centrifuge tank 4 and falling into the collection tank 7, while the rust sinks to the bottom of the centrifuge tank 4.

[0035] Turn off the vertical motor 3, open the cover plate 8, and remove the centrifuge tank 4 through the lifting lug 403. Then, pour out the antifreeze. During the pouring process, the angle formed by the intercepting ring 402 and the conical surface 401 helps to prevent the rust that has settled at the bottom of the centrifuge tank 4 from settling.

[0036] After purification, grip handle 701, lift the collection tank 7 to separate it from the purification bucket 2, and drain the oil through the oil nozzle 702. Pull the fastener 9 out of the groove 202 and remove the oleophilic film 5 for cleaning.
