Description

Technical Field

[0001] The present invention relates to the field of machine tool processing, and particularly to a waste oil recovery device for machine tool processing. Background Art

[0002] A machine tool refers to a machine that manufactures machines, also known as a working machine or a tool machine, and is commonly referred to as a machine tool for short. Generally, it is divided into metal cutting machine tools, forging machine tools, woodworking machine tools, etc. There are many methods for machining mechanical parts in modern mechanical manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and relatively fine surface roughness requirements, they generally need to be finally processed by cutting on a machine tool. When a machine tool processes parts, cutting fluid is required to cool the parts and the processing machine. After the cutting fluid is used up, it will be doped with debris during processing. After the coolant and waste chips are mixed, they form waste liquid, and this waste liquid needs to be recycled. Patent Application No.: CN201922152668.9 discloses a waste liquid recovery and treatment device for machine tool processing, including a housing. An inlet is opened at the top of the housing, and a filter box is fixedly installed inside the housing. A motor is fixedly installed on one side of the filter box. By filtering the waste liquid through the filter box, the cutting fluid and metal chips are separated. However, when recycling the cutting fluid by such a simple filtering method, a certain amount of cutting fluid will remain on the metal chips, resulting in waste of the cutting fluid.

[0003] The present invention is specifically studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a waste oil recovery device for machine tool processing.

[0005] The present invention can be realized through the following technical solutions:

[0006] The present invention discloses a waste oil recovery device for machine tool processing, which comprises a box body. Two filter barrels are symmetrically arranged in the box body. Feed inlets are arranged on the filter barrels. Both ends of the filter barrels are fixed to support plates. A separation motor is also fixed on the box body. A square shaft is fixed to the output end of the separation motor. The square shaft passes through the support plate and is slidably connected to the support plate. A positioning tube rotatably connected to the support plate is also arranged on one of the support plates. A support shaft is fixed on the positioning tube. A turntable is further arranged in the box body below the support shaft. A positioning shaft is fixed on the turntable. The positioning shaft is connected to the aforementioned support shaft through a push rod. The turntable is driven to rotate by a swing motor. A feed pipe with an open upper end is fixed to the bottom inside the box body. A feed shaft is arranged in the feed pipe. The feed shaft is driven to rotate by a feed motor. A feed spiral blade is fixed on the feed shaft. A feed port penetrating the box body is arranged on the box body at the end of the feed pipe. An aggregate box is fixed on the box body at the position of the feed port. A lifting pipe is fixed on the aggregate box. A lifting motor is fixed on the lifting pipe. A lifting shaft is fixed to the output end of the lifting motor. A lifting spiral blade is fixed on the lifting shaft. A discharge pipe is also arranged on the lifting pipe. A liquid discharge port is arranged on the box body. A separation pipe is fixed on the box body at the position of the liquid discharge port. An oil outlet pipe is fixed on the separation pipe. A hose is fixed to the end of the oil outlet pipe. A floating ball is fixed on the hose. The oil outlet at the end of the hose is fixed above the floating ball. A water outlet pipe is fixed to the bottom of the separation pipe. A water inlet pipe is also fixed on the box body.Discharge the waste liquid into the filter barrel inside the box body. Drain tap water into the box body through the water inlet pipe. After the tap water overflows the filter barrel, the cutting fluid floats on the water surface. The swing motor drives the turntable to rotate. The positioning shaft on the turntable drives the filter barrel to move on the square shaft through the push rod. The swing motor drives the filter barrel to swing back and forth on the square shaft. After the metal chips collide with the water, the cutting fluid remaining on the metal chips is washed away by the water and separated from the metal chips. The cutting fluid all floats on the water surface. Drive the square shaft to rotate through the separation motor. The filter barrel with the square shaft rotates along with the square shaft. After the filter barrel containing the debris rotates, the feeding port of the filter barrel faces downward, and the debris falls into the guide pipe. Drive the guide shaft to rotate through the guide motor. The guide spiral blade rotates along with the guide shaft. When the guide spiral blade rotates, it pushes the debris to move. After the metal debris reaches the aggregate box, the lifting motor drives the lifting shaft to rotate, and the lifting spiral blade rotates. When the lifting spiral blade rotates, the debris rises in the lifting pipe and is finally discharged and collected through the discharge pipe. Drain tap water into the box body through the water inlet pipe. After the cutting fluid overflows the liquid discharge port, it is discharged into the separation pipe through the liquid discharge port. After the cutting fluid and water are discharged into the separation pipe, due to the buoyancy effect, the floating ball floats at the stratification position of the cutting fluid and water. The cutting fluid above the floating ball is discharged into the oil outlet pipe through the oil inlet port. The cutting fluid is discharged and collected through the oil outlet pipe, and the water is discharged for treatment through the water outlet pipe. Control the flow rates of the water inlet pipe and the water outlet pipe, and continuously discharge the waste liquid into the box body, and the continuous discharge of the cutting fluid can be achieved. This device can separate the cutting fluid from the metal chips, and through the characteristic that the cutting fluid floats on the water surface, the cutting fluid on the surface of the metal chips can be completely separated by shaking the metal chips in the water, realizing the complete recovery of the cutting fluid and not wasting the cutting fluid.

[0007] Preferably, support rings are also fixed on both sides inside the box body, and the support plate is arranged inside the support rings. The support rings support the support plate to prevent the weight of the filter box from acting on the square shaft.

[0008] Preferably, guide plates are also fixed on both sides inside the box body. The waste liquid slides to the position of the feeding port through the guide plates.

[0009] The present invention has the following advantages compared with the existing technology:

[0010] This device can separate the cutting fluid from the metal chips, and through the characteristic that the cutting fluid floats on the water surface, the cutting fluid on the surface of the metal chips can be completely separated by shaking the metal chips in the water, realizing the complete recovery of the cutting fluid and not wasting the cutting fluid.
