Description

Technical Field

[0001] This utility model relates to the technical field of oil-water separation and recycling devices, specifically an oil-water separation and recycling device for CNC lathe cutting fluid. Background Technology

[0002] The oil-water separation and recycling device for CNC lathe cutting fluid is an environmentally friendly device that can effectively help enterprises save resources and reduce pollution. This device separates the oil and water in the CNC lathe cutting fluid and then recycles them, which not only reduces production costs for enterprises but also protects the environment and reduces water waste. For example, the utility model patent with patent authorization announcement number CN217698034U discloses a vertical automatic self-cleaning recycling and separation device for cutting fluid in machining. This device is applied in the field of cutting fluid treatment technology. The key technical points are: it includes an oil-water separation tank with an opening at the top and an oil-water separation component mounted on it. The oil-water separation tank is divided into an oil tank and a water tank by a partition. The top surface of the partition is lower than the top surface of the oil-water separation tank. The oil-water separation component includes an oil-pushing roller brush mounted in the water tank and a drive component that controls its reciprocating motion. The lowest point of the roller brush is lower than the top surface of the partition. When the liquid level in the water tank is flush with the top surface of the partition, the drive component controls the oil-pushing roller brush to move towards the oil tank. The technical effect is that after the cutting fluid enters the oil-water separation tank and remains still, floating oil floats on the surface of the cutting fluid. Through the movement of the oil-pushing roller brush, the floating oil moves and enters the oil tank, effectively improving the quality of the reused cutting fluid. In the existing technology, the device lacks a sealing mechanism, making it difficult to seal the connection between the fixed pipe and the connecting pipe. This can lead to oil and water leakage at the connection points. Furthermore, the device lacks a filtration mechanism, making it difficult to filter impurities in the oil and water, thus hindering its use. Therefore, improvements to the existing technology are needed. Utility Model Content

[0003] The purpose of this utility model is to provide an oil-water separation and recycling device for CNC lathe cutting fluid. It solves the problems of the lack of a sealing mechanism, the difficulty in sealing the connection between the fixed pipe and the connecting pipe, which may lead to oil and water leakage at the connection between the fixed pipe and the connecting pipe, and the lack of a filtration mechanism when the device is in use, which makes it difficult to filter impurities in the oil and water, making the device inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil-water separation and recycling device for CNC lathe cutting fluid, comprising a housing, a fixed pipe disposed inside the housing, a shell fixedly connected inside the housing, the shell contacting the fixed pipe, a pipe fixedly sleeved inside the shell, an oil-water separator disposed on the pipe, an oil-water separator fixedly installed inside the housing, an oil storage tank disposed at the lower end of the oil-water separator, the oil storage tank contacting the housing, a water storage tank disposed at the lower end of the oil-water separator, the water storage tank contacting the housing, a connecting pipe contacting the left end of the fixed pipe, a sealing mechanism disposed on the outside of the fixed pipe, and a filtering mechanism disposed inside the shell.

[0021] Please see Figures 1-5 A CNC lathe cutting fluid oil-water separation and recycling device includes a housing 1, a fixed pipe 2 inside the housing 1, a shell 3 fixedly connected inside the housing 1, the shell 3 contacting the fixed pipe 2, a pipe 4 fixedly sleeved inside the shell 3, an oil-water separator 5 installed on the pipe 4, an oil-water separator 5 fixedly installed inside the housing 1, an oil storage tank 6 at the lower end of the oil-water separator 5 in contact with the housing 1, a water storage tank 7 at the lower end of the oil-water separator 5 in contact with the housing 1, a connecting pipe 8 at the left end of the fixed pipe 2, a sealing mechanism 9 on the outside of the fixed pipe 2, and a filter mechanism 10 inside the shell 3.

[0022] Please see Figures 1-4The sealing mechanism 9 includes a connecting sleeve 91, which is fixedly connected to the outside of the fixed tube 2. The connecting sleeve 91 contacts the connecting tube 8. A connecting block 92 contacts the inside of the connecting sleeve 91. A handle 93 is fixedly connected to the connecting block 92. An elastic retaining sleeve 94 is snapped into the inside of the connecting sleeve 91 and is fixedly connected to the connecting block 92. The elastic retaining sleeve 94 is designed to limit the movement of the connecting block 92. A guide rod 95 is slidably connected inside the connecting sleeve 91, and a handle 93 is fixedly connected to the guide rod 95. The guide rod 95 is designed to guide the connecting block 92. A semi-circular sleeve 96 is slidably connected inside the connecting sleeve 91. The semi-circular sleeve 96 is fixedly connected to the connecting block 92. A semi-circular sealing sleeve 97 is fixedly connected to the semi-circular sleeve 96. The semi-circular sealing sleeve 97 contacts the connecting sleeve 91, the connecting pipe 8, and the fixed pipe 2. By moving the connecting block 92, the elastic sleeve 94 and the semi-circular sealing sleeve 97 move. The semi-circular sealing sleeve 97 moves and contacts the fixed pipe 2 and the connecting pipe 8. The elastic sleeve 94 moves into the connecting sleeve 91, thereby sealing the connection between the fixed pipe 2 and the connecting pipe 8 and preventing oil and water leakage at the connection between the fixed pipe 2 and the connecting pipe 8 on the device.

[0023] Please see Figure 3 , Figure 5 The filter mechanism 10 includes a filter screen 101. The filter screen 101 is in contact with the housing 3. A motor 102 is fixedly installed on the outside of the housing 3. The rotating shaft of the motor 102 is rotatably connected to the housing 3. A rotating rod 103 is fixedly connected to the lower end of the rotating shaft of the motor 102. An eccentric wheel 104 is fixedly connected to the outside of the rotating rod 103. The eccentric wheel 104 is in contact with the filter screen 101. By designing the eccentric wheel 104, the filter screen 101 can be moved. A support block 105 is fixedly connected inside the housing 3. A slide rod 106 is slidably connected inside the support block 105. A fixing block 107 is fixedly connected to the right end of the slide rod 106. A spring 108 is provided on the outside of the slide rod 106. One end of the spring 108 is fixedly connected to the support block 105, and the other end of the spring 108 is connected to the filter screen 101. 1. Fixed connection: The filter screen 101 is elastic due to the design of spring 108. The slide rod 106 is fixedly connected to the filter screen 101. The inside of the housing 3 is in contact with the cover 109. The inside of the housing 3 is connected by bolts 1010 through threads. The bolts 1010 are in contact with the cover 109. The filter screen 101 can filter oil and water, thereby filtering out impurities in the oil and water, making the device easy to use. When the motor 102 is started, the motor 102 drives the eccentric wheel 104 and other components to rotate. The rotation of the eccentric wheel 104 causes the filter screen 101 to move. When the eccentric wheel 104 moves away from the filter screen 101, the spring 108 pushes the filter screen 101 to move towards the rotating rod 103. This reciprocating motion prevents the filter screen 101 from clogging and reduces its working efficiency.

[0024] The specific implementation process of this utility model is as follows: Before the device is used, the movable connecting pipe 8 moves towards the connecting sleeve 91. After the connecting pipe 8 moves to the designated position inside the connecting sleeve 91, the movable handle 93 moves towards the connecting sleeve 91. The movement of the handle 93 drives the connecting block 92 and the guide rod 95 to move. The movement of the connecting block 92 drives the elastic sleeve 94 and the semi-circular sleeve 96 to move. The movement of the semi-circular sleeve 96 drives the semi-circular sealing sleeve 97 to move. After the semi-circular sealing sleeve 97 moves and contacts the connecting pipe 8 and the fixed pipe 2, the elastic sleeve 94 moves into the connecting sleeve 91, thereby sealing the connection between the fixed pipe 2 and the connecting pipe 8 and preventing oil and water leakage at the connection between the fixed pipe 2 and the connecting pipe 8 on the device.

[0025] When the device is in use, oil and water flow from the connecting pipe 8 through the fixed pipe 2 into the housing 3. The filter screen 101 filters the oil and water, thereby filtering out impurities and making the device easy to use. When the device is used for a long time, the motor 102 is started, and the motor 102 drives the rotating rod 103 to rotate. The rotation of the rotating rod 103 drives the eccentric wheel 104 to rotate. The rotating eccentric wheel 104 strikes the filter screen 101, causing the filter screen 101 to move towards the spring 108. The movement of the filter screen 101 drives the sliding rod 106 to move, and the movement of the sliding rod 106 drives the fixed block 107 to move. The movement of the filter screen 101 compresses the spring 108. After the eccentric wheel 104 rotates away from the filter screen 101, the elastic force of the spring 108 pushes the filter screen 101 to move towards the rotating rod 103. This process is repeated to prevent the filter screen 101 from clogging and to prevent the working efficiency of the filter screen 101 from decreasing.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
