It overcomes the problems of traditional soap-based emulsions being prone to odor in summer, difficult to dilute in winter, and poor rust prevention effect, and has no adverse effect on lathe paint. It is suitable for the cutting and grinding of ferrous metals and is the most advanced grinding product at present. All indicators of cutting fluid are superior to those of saponified oil. It has good cooling, cleaning, rust prevention and other characteristics, and also has the characteristics of being non-toxic, odorless, non-corrosive to the human body, non-corrosive to equipment, and non-polluting to the environment.
[0003] During the use of existing machining chip coolant filtration devices, only large-volume iron chips and small-volume iron chips can be isolated and filtered. However, as the usage time increases, under the influence of water pressure, the filter layer inside the filter element will be damaged by large-volume iron chips. At the same time, it is extremely inconvenient to clean large-volume iron chips inside the filter element. Therefore, in view of these current situations, there is an urgent need to develop a machine tool cutting fluid purification device to meet the actual usage requirements. Content of the Utility Model

Detailed implementation mode

The content mentioned in the implementation mode does not limit the present invention. The present invention will be described in detail below in conjunction with the drawings.
[0022] Please refer to Figures 1-5 , the machine tool cutting fluid purification device implemented specifically thereof includes a filtering component 1 and a waste water collecting member. The waste water collecting member is used to be conductively connected between the filtering component 1 and the machine tool. The waste water collecting member is composed of a collecting hopper 2 in a "shovel bucket" shape. A plurality of blocking inclined plates 23 are arranged in a linear array structure, and the adjacent two blocking inclined plates 23 are in a parallel structure to each other. The gaps between the adjacent two blocking inclined plates 23 are kept consistent. One side of the collecting hopper 2 is provided with a lathe connection port 21 for connecting an external machine tool, and one side of the collecting hopper 2 is provided with a connecting pipe body 22 for connecting the filtering component 1. A plurality of blocking inclined plates 23 are arranged inside the collecting hopper 2, and the upper edge of the blocking inclined plate 23 is inclined towards the side of the lathe connection port 21. The lower edge of the blocking inclined plate 23 is integrally formed with the inside of the collecting hopper 2.
[0023] By using the collecting hopper 2 in a "shovel bucket" shape as the first-layer filtering member between the filtering component 1 and the machine tool, when the cutting fluid flows through the collecting hopper 2 from top to bottom, the larger iron filings can be effectively accumulated in the gap between the blocking inclined plate 23 and the collecting hopper 2 through the blocking inclined plate 23 inclined towards the side of the lathe connection port 21. The smaller iron filings can flow to the filtering component 1 along with the cutting fluid for further filtering and purification, and the situation that the larger iron filings damage the internal filter layer of the filter element 3 can be effectively reduced.
[0024] The structure of the filtering component 1 is specifically as Figure 3As shown in the figure, the filtering component 1 includes a top cover 4, a housing 5 and a filter element 3. Inside the top cover 4, there is a diversion pipe body 41 for connecting the filter element 3 and the connecting pipe body 22. The diversion pipe body 41 is a pipe body with a tee structure. One end of the diversion pipe body 41 is an inflow pipe orifice 411, and the inflow pipe orifice 411 is conductively connected to the connecting pipe body 22. The filter element 3 is a cylindrical hollow structure, and the side wall of the filter element 3 is a porous structure with dense filter holes. One end of the filter element 3 close to the top cover 4 is provided with a protruding filter element interface 31. The bottom of the diversion pipe body 41 has two diversion pipe orifices 412, and the filter element interface 31 is conductively connected to the corresponding diversion pipe orifice 412. The housing 5 is a cylindrical structure, and the inside of the housing 5 is an inner cavity 51 with an upward opening. An internal thread 52 is provided at the top opening of the housing 5, and a matching external thread 42 is provided at the bottom of the top cover 4. The top cover 4 is threadedly connected to the top opening of the housing 5, and the filter element 3 is embedded inside the inner cavity 51.
[0025] In a further solution, as Figure 5 shown in the figure, a liquid extraction pipe body 53 is provided at the bottom of the housing 5. The top end of the liquid extraction pipe body 53 is a hollowed-out part 531 with a porous structure. The hollowed-out part 531 of the liquid extraction pipe body 53 extends into the inner cavity 51 for conductive connection. The bottom end of the liquid extraction pipe body 53 is a connection part 532, and the connection part 532 is used to connect an external water pump. The bottom end of the filter element 3 is provided with an upwardly concave positioning groove 32. The hollowed-out part 531 of the liquid extraction pipe body 53 extends upward into the positioning groove 32. Through the filter element interface 31 and the positioning groove 32, the filter element 3 can be stably arranged at the center of the inner cavity 51. Then, by providing negative pressure through an external water pump, a water pressure difference is formed inside and outside the filter element 3, so as to extract the cutting fluid inside the filter element 3 to the outside. Iron filings with a smaller volume can be filtered through the porous structure with dense filter holes on the side wall of the filter element 3.
[0026] The working process of the machine tool cutting fluid purification device: Fix the lathe connection port 21 at one end of the collection hopper 2 at the waste discharge of the machine tool. The other end of the collection hopper 2 is conductively connected to the connecting pipe body 22 through the inflow pipe orifice 411. When the cutting fluid flows through the collection hopper 2 from top to bottom, by means of a blocking inclined plate 23 inclined to one side of the lathe connection port 21, iron filings with a larger volume are accumulated in the gap between the blocking inclined plate 23 and the collection hopper 2. Then, by providing negative pressure through an external water pump, a water pressure difference is formed inside and outside the filter element 3, so as to extract the cutting fluid inside the filter element 3 to the outside. Iron filings with a smaller volume can be filtered through the porous structure with dense filter holes on the side wall of the filter element 3.
