[0058] The machine tool 200 may be a numerically controlled machine tool or a common machine tool, etc. The parts may be parts made of metal or non-metal materials, which are not limited here.

[0059] In order to reduce production costs and achieve energy conservation and emission reduction, it is usually necessary to filter the cutting fluid, and use the filtered cutting fluid as new coolant to enter the machine tool 200 for circulation.

[0060] The filter system 100 is usually used to filter the cutting fluid. With the acceleration of modern production rhythm and the improvement of machining efficiency of machine tools 200, and the rapid development of heavy equipment such as large ship engines and heavy locomotive engines, super-large parts need to be processed by large horizontal machining centers. The shapes of its parts are also varied, and the machining procedures are complex and varied. The actual needs for high-precision machining and other different needs have significantly increased the chip removal function and high-precision filtering of the filter system 100.

[0061] The filter system 100 of this embodiment is separately arranged from the machine tool 200, so that the machine tool 200 can move independently, and multiple machine tools 200 can share the filter system 100, which has a high degree of integration. At the same time, the filter system 100 is separately arranged from the machine tool 200, which facilitates the filter system 100 to be larger, meets the filtering of large flow cutting fluid of the machine tool 200, and can also reduce the frequency of cleaning and maintenance of the filter system 100 by the user, thereby improving the user experience.

[0062] Specifically, if Figure 1-Figure 3As shown, the filtering system 100 provided in this embodiment includes a chip removal device 10, a filtering device 20 and a cooling device 30. The chip removal device 10 is used to receive the cutting fluid discharged from the machine tool 200 and includes a first filtering mechanism 11. The first filtering mechanism 11 includes a plurality of filter elements 111 arranged at intervals. The cross section of the filter element 111 is in the shape of an inverted triangle. The filter element 111 is used to filter the cutting fluid once. The filtering device 20 is used to receive the cutting fluid filtered by the filter element 111 and filter the cutting fluid twice. The cooling device 30 is used to cool the cutting fluid filtered by the filtering device 20. Among them, the cooling device 30 can be any existing air cooling device or water cooling device that can achieve the above functions.

[0063] The cutting fluid is filtered once by the chip removal device 10 to filter out most of the chips in the cutting fluid, and the cutting fluid filtered by the chip removal device 10 is filtered twice by the filtering device 20, thereby improving the filtering effect and filtering accuracy of the cutting fluid, so that the cutting fluid meets the conditions for recycling and reduces the production cost; by setting a plurality of inverted triangular filter elements 111 to filter the chips in the cutting fluid, the filtering effect can be improved, and it is not easy to be blocked, which is beneficial to improving the filtering efficiency; by cooling the cutting fluid filtered by the filtering device 20 for the second time by the cooling device 30, the cutting fluid can be directly circulated to the machine tool 200 side for recycling, so as to facilitate continuous production.

[0064] Optionally, the filtration system 100 further includes a power mechanism 50, which is used to provide power to the cutting fluid so that the cutting fluid flows between the machine tool 200, the chip removal device 10, the filtering device 20, and the cooling device 30. Specifically, the power mechanism 50 can be any pump in the prior art that can achieve the above functions.

[0065] Optionally, the chip removal device 10 further includes a conveying mechanism and a supporting mechanism 14 . The conveying mechanism is disposed on the supporting mechanism 14 . The conveying mechanism is used to convey and transfer the chips filtered by the filtering mechanism. The supporting mechanism 14 is used to support the conveying mechanism.

[0066] Specifically, Figure 1 The support mechanism 14 shown includes a mounting frame 141, a conveying mechanism is arranged on the mounting frame 141, and casters 142 are arranged under the mounting frame 141 to facilitate the movement of the chip removal device 10. Furthermore, an adjustable foot cup 143 is also arranged under the mounting frame 141 to facilitate the fixing of the chip removal device 10 during operation.

[0067] Specifically, the conveying mechanism includes a first driving member 12, a conveying member and a scraper, wherein the conveying member is arranged at the output end of the driving member, the scraper is arranged outside the conveying member, the filter 111 is located between the conveying member and the scraper, and the first driving member 12 is used to drive the conveying member and the scraper thereon to move. The first driving member 12 may be a motor. The conveying member may be an existing chain plate conveying mechanism or a belt conveying mechanism.

[0068] Optionally, there are multiple scrapers, which are arranged on the transmission member at intervals along the direction of travel of the transmission member to improve the scraping effect on the chips. Optionally, at least one scraper is provided with a brush on one side facing the filter 111 to further improve the scraping effect on the chips.

[0069] Optionally, the chip removal device 10 also includes a chip removal duct, which is arranged at the end of the conveying mechanism. The chip removal duct extends in a vertical direction, and can realize centralized discharge of chips, avoiding the chips from falling due to inertia, which makes it inconvenient to collect the chips.

[0070] Optionally, the chip removal device 10 further includes a slag receiving box, which is directly opposite to the chip removal pipe and is used to receive, store and transfer the chips transported by the conveyor to achieve centralized processing of the chips.

[0071] Optionally, the first filtering mechanism 11 further includes a second filtering water tank 112 , which is disposed below the filtering element 111 and is used to receive the cutting fluid filtered by the filtering element 111 .

[0072] Optionally, the chip removal device 10 further includes a first detection member 13, which is disposed in the second filter water tank 112. The first detection member 13 is used to detect the liquid level of the cutting fluid filtered by the filter member 111 in the second filter water tank 112. When the first detection member 13 detects that the cutting fluid in the second filter water tank 112 reaches a preset height of the first detection member 13, the power mechanism 50 discharges the cutting fluid in the second filter water tank 112. Specifically, the first detection member 13 may be a liquid level sensor.

[0073] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the filtering device 20 includes a second filtering mechanism 21 and a first filtering water tank 22. The second filtering mechanism 21 is used to receive and filter the cutting fluid filtered by the filter element 111. The first filtering water tank 22 is arranged below the second filtering mechanism 21. The first filtering water tank 22 is used to receive the cutting fluid filtered by the second filtering mechanism 21.

[0074] Optionally, the filtering device 20 includes a shell 23, and the second filtering mechanism 21 includes a unwinding roller 211, a winding roller 212 and a paper pressing roller 214. The second filtering mechanism 21 includes the unwinding roller 211, the winding roller 212 and the paper pressing roller 214, which are all arranged on the shell 23. The unwinding roller 211 is used to apply filter paper 213, and the filter paper 213 is wound under the paper pressing roller 214. The winding roller 212 is used to provide traction to the filter paper 213 so that the filter paper 213 can move relative to the paper pressing roller 214.

[0075] Optionally, the paper pressing roller 214 has a filter chamber 2141. During filtering, the power mechanism 50 transfers the cutting fluid filtered once by the chip removal device 10 to the filter chamber 2141, and performs secondary filtration on the cutting fluid through the filter paper 213. The filter paper 213 has a filtration accuracy of up to 30 μm, and has high filtration accuracy. The filtered cutting fluid has high cleanliness and can be recycled.

[0076] Alternatively, if Figure 6 As shown, the first filtered water tank 22 includes a box body 221 and a flow-reducing member 222. The flow-reducing member 222 is arranged in the box body 221 and is directly opposite to the second filtering mechanism 21. The flow-reducing member 222 is arranged to be tilted downward. The flow-reducing member 222 is used to slow the flow of the cutting fluid filtered by the second filtering mechanism 21 to prevent the cutting fluid from directly falling into the box body 221 to generate foam, thereby preventing the foam from affecting the operation of the power mechanism 50 and the cleanliness of the cutting fluid.

[0077] Optionally, the filtering mechanism further includes a third detection member 224, which is configured to detect the liquid level of the filter chamber 2141. The cutting fluid penetrates through the filter paper 213 and falls into the box body 221. The filtered chips remain on the filter paper 213. As the chips on the filter paper 213 increase, the liquid level in the filter chamber 2141 rises. When the liquid level in the filter chamber 2141 reaches the preset height of the third detection member 224, the filtering effect of the filter paper 213 in the chip filtering state has been reduced and can no longer continue to perform the filtering work. After being triggered, the third detection member 224 sends a signal to start the winding roller 212, and the filter paper 213 part supporting the chips is pulled out of the filter chamber 2141. During the transmission process, the new filter paper 213 part is supplied from the unwinding roller 211 to the bottom of the paper pressing roller 214 to continue the filtering operation. Among them, the third detection member 224 is a liquid level sensor.

[0078] Optionally, the second filtering mechanism 21 further includes a second detecting member 215, which is disposed in the box body 221 and is configured to detect the liquid level of the cutting fluid in the box body 221. When the second detecting member 215 detects that the cutting fluid in the box body 221 reaches a preset height of the second detecting member 215, the power mechanism 50 discharges the cutting fluid in the box body 221. Specifically, the second detecting member 215 is a liquid level sensor.

[0079] Optionally, the filtering device 20 includes a chip box 24 , which is used to receive, store and transport the chips filtered on the filter paper 213 .

[0080] Alternatively, if Figure 6 and Figure 7 As shown, the first filtered water tank 22 includes a spacer 223, which is arranged in the box body 221 and divides the box body 221 into a first cavity 2211 and a second cavity 2212. A notch 2231 is provided on the spacer 223 to connect the first cavity 2211 with the second cavity 2212. The cutting fluid filtered by the filter paper 213 falls into the first cavity 2211 after slow flow through the slow flow member 222, and the sludge in the cutting fluid is precipitated at the bottom of the first cavity 2211. The clean water in the cutting fluid enters the second cavity 2212 through the notch 2231, thereby further improving the cleanliness of the cutting fluid.

[0081] Alternatively, if Figure 6 and Figure 7 As shown, a baffle 225 is provided in the box 221, and the baffle 225 is located in the second cavity 2212. An oil skimmer is provided above the second cavity 2212. The baffle 225 can prevent the cutting fluid from generating large fluctuations when the oil skimmer skims the oil, thereby affecting the skimming effect. It should be noted that the oil skimmer can adopt a conventional structure in the prior art, which will not be described in detail here.

[0082] The filtering system 100 further includes a control mechanism 40 , which is disposed on the filtering device 20 . The power mechanism 50 , the chip removal device 10 , the filtering device 20 and the cooling device 30 are electrically connected to the control mechanism 40 respectively to coordinate and control the mechanisms to cooperate with each other.

[0083] This embodiment also provides a method for using the filtration system, which is completed using the above-mentioned filtration system 100 and includes the following steps:

[0084] The filter system 100 is placed on one side of the machine tool 200;

[0085] The power mechanism 50 transfers the cutting fluid generated by the machine tool 200 to the chip removal device 10, and the chip removal device 10 performs a primary filtration on the cutting fluid;

[0086] The power mechanism 50 transfers the cutting fluid filtered once by the chip removal device 10 to the filtering device 20, and the filtering device 20 performs secondary filtering on the cutting fluid;

[0087] The power mechanism 50 transfers the cutting fluid after secondary filtration by the filter device 20 to the cooling device 30, and the cooling device 30 cools the cutting fluid;

[0088] The power mechanism 50 transfers the cutting fluid cooled by the cooling device 30 to the machine tool 200 .

[0089] By using the above-mentioned filtering system, the filtering effect and filtering accuracy of the cutting fluid are improved, so that the cutting fluid meets the conditions for recycling and reduces the production cost.

[0090] During the secondary filtration of the cutting fluid by the filter device 20 , the cutting fluid filtered by the second filter mechanism 21 enters the box body 221 through the slow flow member 222 to prevent the cutting fluid from mixing with air to generate bubbles and affect the operation of the power mechanism 50 .

[0091] When the cutting fluid enters the box 221, the cutting fluid first enters the first cavity 2211, where the sludge is precipitated. The precipitated cutting fluid flows through the notch 2231 to the second cavity 2212, thereby separating the sludge and improving the cleanliness of the cutting fluid.
