technical field

The invention relates to the technical field of industrial machinery, in particular to a cutting fluid filtration and separation device.

Background technique

Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. It is made of a variety of super functional additives through scientific compounding. Cutting fluids have a common disadvantage, that is, after a certain period of use, the cooling and lubricating effect will decline rapidly, and they will deteriorate and fail, and become industrial waste fluids. If they are directly discharged, they will pollute the environment. Therefore, it is necessary to filter and separate the cutting fluid to prolong the service life of the cutting fluid. The service life is reduced, the discharge of waste cutting fluid is reduced, and the concept of clean production and circular economy is realized.

The Chinese patent application number 201710681254.8 discloses a cutting fluid purification device and its purification process. The device includes an oil skimming settling device, a magnetic filtering device, a cyclone separation device, and an adjusting device. The fine non-metallic impurities are separated from the cutting fluid, and finally sterilized by the adjustment device. However, when the device is processing waste liquid, the first step is to wait for the floating oil in the waste liquid to be completely removed by the oil skimming and settling device before opening the second part of the switch for the next step of processing. The processing time is longer, and due to The use of the entire skimming settling device and adjustment device makes it more expensive.

For example, Yuhuan Senke Machinery Factory produces GL2 series flat screen magnetic roll paper tape filter which is composed of magnetic separator and gravity paper tape filter. After the primary filtration of magnetic separator, most of the magnetic particles are adsorbed. Gravity paper belt filter, using the gravity of the liquid to push the liquid through the filter paper and into the storage tank below the filter, debris and slick oil are deposited on the paper belt, but when the capillary pores of the filter paper are covered with debris or oil When the floating objects are clogged, the filtering capacity will drop, so new filter paper must be added to the work, and new filter paper needs to be replaced continuously. The devices using filter paper for filtering are not only a waste of resources, but also have limited filtering capacity and low working efficiency. Low, suitable for use in lower flow situations, as the flow increases, the size of the filter will increase, it will take up more space in the factory, and the larger filter tank will make cleaning work cumbersome Therefore, it is an urgent problem to provide a dynamic cutting fluid filtration and separation device capable of simultaneously and continuously separating impurities, dirty oil, and cutting fluid.

The transmission mechanism 8.11 (see Figure 15) includes a motor 8.111, a small bevel gear 8.112, and a large bevel gear 8.113; A large bevel gear 8.113 is installed on 8.10, the large bevel gear 8.113 and the small bevel gear 8.112 mesh with each other, the vertical shaft 8.10 is fixed on the bottom of the support 8.9 through the bearing 8.114 with a seat, and the motor 8.111 and the vertical shaft 8.10 realize the reversing transmission through two bevel gears , driven by the motor 8.111 to rotate the vertical shaft 8.10.

The support 8.9 supports the transmission mechanism 8.11 and the vertical shaft 8.10. The lower end surface of the drum 8.5 is installed on the inner bottom surface of the drum support box 8.12. The lower side of the drum supporting box 8.12 is fixed on the upper end face of the bearing 8.9, which can support the drum 8.5 and ensure the stability of the drum 8.5 when it rotates. The lower half of the drainage layering mechanism 8.3 is on the upper side of the drum 8.5, and the disc shaft 8.8 is on the lower side of the drum 8.5. There is a group of disc-shaped parts nested together on the disc shaft 8.8 - the disc Sheet 8.7, the lower end of disc shaft 8.8 is fixed on the inner bottom surface of rotating drum 8.5. There are uniform holes on the lower side of the disc shaft 8.8, so that the cutting fluid can flow into the drum 8.5. There is a disc-shaped oil storage plate 8.32 and a cutting fluid storage plate in the drainage layering mechanism 8.3 on the upper end of the drum 8.5. 8.32, oil storage plate 8.32 and cutting fluid storage plate 8.33 are equipped with upper cover 8.1 on the outside, which can create a closed space to prevent leakage and accumulation of cutting fluid and oil. When the cutting fluid pumped up by the water pump 7 after removing impurity particles is fed into the inside of the drum 8.5 through the feed pipe 8.31 and the disc shaft 8.8 located in the center of the drum, the transmission mechanism 8.11 is driven by the motor 8.111 to drive the vertical shaft 8.10 to rotate, and the vertical shaft 8.10 The rotation drives the drum 8.5 to rotate, and the drum 8.5 rotates to drive the disc shaft 8.8 to rotate. The disc shaft 8.8 drives the disc 8.7 to rotate at high speed with the drum 8.5. The oil is separated, so that the heavy liquid cutting fluid accumulates in the part with the largest inner diameter of the drum 8.5, that is, it is thrown to the wall of the drum 8.5, and gathers upward along the wall of the drum 8.5, and passes through the passage of the outer hollow cylinder of the feeding pipe 8.31. The hole flows into the cutting fluid storage plate 8.33, and flows out through the cutting fluid outlet 8.103 of the disc separator, and the light liquid dirty oil flows along the outer side of the disc 8.7 to the center of the inner side (there is a small hole on the cylindrical part of the disc 8.7, which is convenient The oil gathers to the upper side into the through hole of the inner hollow cylinder of the feed pipe 8.31), and converges upward through the through hole of the inner hollow cylinder of the feed pipe 8.31, flows into the oil storage plate 8.32, and exits through the disc separator The oil port 8.101 flows to the oil tank 6, so as to realize the separation of dirty oil and high-purity cutting fluid.
