Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid treatment, in particular to a cutting fluid purification and recovery treatment device. Background Technique

[0002] Cutting fluid has the functions of lubricating, cooling and cleaning the cut parts. Cutting fluid has become an indispensable part of the machining industry. After being used for a period of time, due to a large amount of particles generated by cutting, grinding, shearing and drilling, its oiliness will cause the growth of microorganisms, so there will be peculiar smell, or even stinking phenomenon, making the waste cutting fluid difficult to recycle and unable to be directly discharged.

[0003] When the existing cutting fluid recovery device purifies the cutting fluid, the cutting fluid after one-time purification usually still contains some impurities and needs to be purified repeatedly. Such operation has low efficiency and consumes more time, which brings certain adverse effects to the process of cutting fluid purification and recovery. In order to solve the deficiencies of the existing technology, we propose a cutting fluid purification and recovery treatment device. Content of the Utility Model

[0012] Advantageous Effects

[0013] Compared with the prior art, the present utility model has the following advantageous effects:

[0014] 1. In this utility model, through the arranged first filter screen, second filter screen, circulation cylinder and spiral blades, the device can perform circulation treatment after filtering the cutting fluid, enabling the cutting fluid that has not been completely filtered to re-enter the interior of the purification barrel through the circulation cylinder for re-filtering, making the purification treatment of the cutting fluid by the device more complete. Moreover, the process of circulation treatment is highly automated, convenient and fast. The cutting fluid enters the connecting cylinder in the middle of the purification barrel through the liquid inlet pipe and the installation pipe, flows out through the through holes on the outer wall of the connecting cylinder, and after being purified by the two layers of first filter screens, it flows into the lower layer through the liquid leakage holes. Then, after being filtered by the two groups of second filter screens, it flows into the interior of the collection barrel through the discharge cylinder in the middle of the second mounting plate. The cutting fluid that has not passed through the second filter screen will flow into the interior of the circulation cylinder through the backflow outlet pipe. The motor at the lower end of the circulation cylinder starts to drive the rotating rod to rotate. When the rotating rod rotates, it drives the spiral blades on the outer wall to rotate, transporting the cutting fluid inside the circulation cylinder upward, and then re-entering the interior of the purification barrel through the backflow inlet pipe for filtration treatment until it passes through the filtration of the second filter screen, making the purification of the cutting fluid more complete.

[0015] 2. In this utility model, through the arranged air compressor, pressure can be increased inside the purification barrel, enabling the cutting fluid to flow faster in the middle of the connecting cylinder, and also making the filtration speed between the first filter screen and the second filter screen faster, thus making the filtration treatment more efficient. After the cutting fluid enters the interior of the installation pipe from the liquid inlet pipe, the air compressor starts, intakes air from the air inlet pipe, and conveys air to the middle of the installation pipe, increasing the pressure in the middle of the installation pipe, making the liquid flow rate inside the installation pipe faster, and thus making the filtration more efficient and saving time.
