Description

Technical Field

[0001] The utility model belongs to the field of cutting fluid treatment equipment, and particularly relates to an oil-water separation structure for chip removal of machine tools. Background Art

[0002] Cutting fluid plays a crucial role in machine tool processing. Cutting fluid can absorb and carry away the heat generated during the cutting process, effectively reducing the temperature of the workpiece and the tool, preventing workpiece deformation and tool wear, and thus improving the processing quality. By forming a lubricating film to reduce the direct contact between the metal and the tool, thereby reducing wear and heat generation, cutting fluid can also flush the cutting area, carry away impurities such as chips and metal powders, keep the cutting area clean, and contribute to improving the machining accuracy and surface quality.

[0003] A large amount of waste cutting fluid is generated during machine tool processing, which contains a large amount of metal processing debris. Water usually occupies most of the total volume of the waste cutting fluid. In addition, it contains lubricants such as mineral oil and synthetic oil, which play a role in lubricating the cutting process and reducing friction and wear.

[0004] The waste cutting fluid contains a large amount of harmful substances such as organic solvents and heavy metals. If it is discharged into the environment at will, it will seriously pollute surface water and groundwater.

[0005] To treat waste cutting fluid, oil-water separation must be carried out first. For example, the utility model patent with the publication number CN221432265U has the following content: The utility model discloses a modular cutting oil-water separator for a machining center. The utility model includes a machine body, a first drain pipe, a second drain pipe, and a filter box. A first observation window and a second observation window are sequentially arranged on the machine body. An oil suction pipe is arranged on the left side of the machine body, and a floating cylinder is arranged at the bottom of the oil suction pipe. The first drain pipe is arranged at the bottom of the machine body, and a first valve is arranged on the first drain pipe. The second drain pipe is arranged at the bottom of the machine body, and a second valve is arranged on the second drain pipe. The filter box is rotatably connected to the top of the machine body through a hinge. The first drain pipe provided by the utility model can discharge more cutting fluid, while the second drain pipe has a small diameter and is transparent, and can discharge less cutting fluid to completely separate oil and water. Then, the first observation window and the second observation window are provided so that the user can view the oil and water inside the machine body in real time for separation.

[0006] The above-mentioned utility model patent can only play a preliminary oil-water separation role for the cutting fluid that has been significantly stratified. However, in actual production, in order to improve the stability and lubricity of the waste cutting fluid, lubricants and water are often fully mixed to form an emulsion-like cutting fluid, and the emulsified cutting fluid cannot be fully separated by the above-mentioned equipment. Content of the Utility Model

[0007] To solve the above technical problems, the present utility model provides the following technical solutions: An oil-water separation structure for chip removal of a machine tool, comprising a material bin, a centrifugal motor assembly, a chip removal assembly and a chemical addition assembly.

The second cylinder is rotatably installed inside the first cylinder, and the height of the second cylinder is lower than that of the first cylinder.

[0009] Further, a sealing ring that fits the inner wall of the first cylinder is provided along the upper edge of the second cylinder.

[0010] A liquid inlet pipe is provided on the left side of the wall of the first cylinder, a chemical addition pipe is provided on the right side of the wall of the first cylinder, and an oil discharge pipe is provided on the rear side of the wall of the first cylinder. The liquid inlet pipe is connected to the chip removal assembly, the chemical addition pipe is connected to the chemical addition assembly, and the oil discharge pipe is connected to an oil absorption assembly.

[0011] Further, the chip removal assembly includes a chip removal housing. The bottom of the chip removal housing is connected to the liquid inlet pipe.

A filter basket inlet corresponding to the raw water pipe is provided on the upper side of the filter basket, and a handle is provided above the filter basket.

[0012] Further, the oil absorption assembly includes a hose. The upper end of the hose is connected to the oil discharge pipe, and a float is provided at the lower end of the hose.

[0013] The centrifugal motor assembly is connected below the first cylinder. The centrifugal motor assembly includes a centrifugal motor assembly housing. A centrifugal motor is vertically arranged upward inside the centrifugal motor assembly housing. The output shaft of the centrifugal motor passes through the bottom plate of the first cylinder, and the end of the output shaft of the centrifugal motor is fixedly connected to the bottom of the second cylinder.

[0014] Further, support feet for support are provided at the bottom of the centrifugal motor assembly housing.

[0015] Further, transparent windows are provided on the walls of the first cylinder and the second cylinder.
