Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a machine tool coolant impurity filtration device. Background Technology

[0002] When a machine tool is machining parts, the temperature at the cutting edge rises. If it is not cooled in time, the tool will deform due to heat, affecting its service life. Therefore, coolant is usually sprayed onto the tool during machine operation. This reduces the temperature of both the tool and the workpiece during machining, and also improves cutting performance and the quality of the machined surface.

[0003] Currently, in order to save energy and protect the environment, the coolant used in machine tools is mostly filtered and then pumped back to the coolant tank for recycling. The filtration method is usually to add a filter screen at the return port to remove impurities. This filtration method has limited filtration effect and is not ideal, and there is a risk of damaging the coolant pump and the workpiece. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a machine tool coolant impurity filtration device, including a box with an open top. A crossbeam is fixedly installed on the box at the opening, and the crossbeam divides the opening of the box into two interconnected areas. A first filter element located in one area is detachably connected to the box for preliminary filtration of the coolant. A limiting member is provided in the box below the crossbeam, and a second filter element is slidably connected to the limiting member. A coolant pump located in the other area is fixedly installed on the box.

[0005] Furthermore, the first filter element includes a frame with a feed inlet at the top, the frame being detachably connected to the housing, and a mounting hole at the bottom of the frame, and a first filter screen located at the mounting hole is provided on the frame.

[0006] Furthermore, a support plate is fixedly installed at the opening of the box body. There are two support plates, which are arranged on the two opposite inner surfaces of the box body. Several equidistant limiting pins are provided at the bottom of the frame body. The surface of the support plate is provided with limiting holes that are adapted to the limiting pins.

[0007] Furthermore, the limiting component includes a fixing plate fixedly installed inside the box, and there are two fixing plates arranged symmetrically. A bent plate is fixedly installed on one side surface of the fixing plate, and a slide is formed between the bent plate and the adjacent fixing plate. The second filter element is slidably connected in the slide.

[0008] Furthermore, the second filter element includes a panel, which is slidably connected within the slide rail, and the panel surface has perforations, with a second filter screen located at the perforations on the panel.

[0009] Furthermore, the mesh count of the second filter screen is greater than that of the first filter screen.

[0010] Furthermore, an inclined plate is provided inside the box, and the lower end of the inclined plate abuts against one side surface of the fixed plate.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a first filter element to perform preliminary filtration of the coolant, intercepting larger impurities; and the first filter element is detachably connected to the housing, making it convenient to clean or replace the first filter screen regularly. The second filter element further filters the coolant, and the mesh size of the second filter screen is larger than that of the first filter screen, which can more finely intercept tiny impurities. Multi-stage filtration effectively improves the filtration effect of the coolant and reduces the damage of impurities to the coolant pump and the workpiece. The top opening of the housing is divided into two areas by a crossbeam, where the first filter element and the coolant pump are respectively installed. The layout is reasonable, makes full use of the housing space, and makes the device structure compact. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] In the embodiments, by Figure 1-3 Provided is a machine tool coolant impurity filtration device, comprising a housing 1 with an open top, a crossbeam 2 fixedly mounted on the housing 1 at the opening, dividing the opening of the housing 1 into two interconnected areas, a first filter element 3 detachably connected to the housing 1 in one area for preliminary filtration of the coolant, a limiting member 4 located below the crossbeam 2 inside the housing 1, and a second filter element 5 slidably connected to the limiting member 4, and a coolant pump 6 fixedly mounted on the housing 1 in the other area, the coolant flowing after machine tool use to the opening at the top of the housing 1. At this location, the crossbeam 2 divides the opening of the housing 1 into two areas. The coolant enters the area equipped with the first filter element 3. Before entering this area, the coolant undergoes preliminary filtration through the first filter element 3 to intercept larger impurities in the coolant. The two areas are interconnected, and a second filter element 5 is installed between the two areas. The coolant undergoes secondary filtration through the second filter element 5 to further intercept tiny impurities, achieving deep purification of the coolant. The clean coolant after two stages of filtration enters the other area equipped with a coolant pump 6, which pumps the filtered coolant back to the coolant tank, realizing the recycling of the coolant.

[0020] Reference Figure 1-3 The first filter element 3 includes a frame 31 with a feed inlet at the top. The frame 31 is detachably connected to the box 1, and the bottom of the frame 31 has an installation hole 32. A first filter screen 33 located at the installation hole 32 is provided on the frame 31.

[0021] With the above-described structure, the coolant accumulates inside the frame 31 and passes through the first filter screen 33 located at the mounting hole 32 at the bottom of the frame 31 under the action of gravity. The first filter screen 33 intercepts impurities in the coolant that are larger than its pore size inside the frame 31, allowing the filtered coolant to flow out of the frame 31 through the first filter screen 33, thus completing the initial filtration.

[0022] Reference Figure 1-3 In this case, a support plate 7 is fixedly installed at the opening of the box 1. There are two support plates 7, which are arranged on the two opposite inner surfaces of the box 1. A number of equidistant limiting pins 8 are provided at the bottom of the frame 31. The support plate 7 has limiting holes 9 that are adapted to the limiting pins 8.

[0023] With the above-mentioned structural design, the first filter element 3 can be limited within the limiting pin 8 and the limiting hole 9, preventing the first filter element 3 from shifting during filtration, and also facilitating the cleaning or replacement of the first filter element 3.

[0024] Reference Figure 1-3 The limiting member 4 includes a fixing plate 41 fixedly installed inside the box 1, and there are two fixing plates 41 arranged symmetrically. A bending plate 42 is fixedly installed on one side surface of the fixing plate 41, and a slide 43 is formed between the bending plate 42 and the adjacent fixing plate 41. The second filter element 5 is slidably connected in the slide 43.

[0025] With the above structural arrangement, rubber pads are provided on the opposite side surfaces of the fixing plate 41 and the bending plate 42, and the rubber pads are located on the slide 43. When the second filter element 5 is located in the slide, the rubber pads on both sides squeeze the panel 51 to prevent coolant from leaking out from the gap between the limiting member 4 and the second filter element 5, thus preventing insufficient filtration.

[0026] Reference Figure 1-3 The second filter element 5 includes a panel 51, which is slidably connected in the slide rail 43. The panel 51 has a perforation 52 on its surface, and a second filter screen 53 located at the perforation 52 is provided on the panel 51.

[0027] Reference Figure 1-3 The second filter screen 53 has a larger mesh size than the first filter screen 33.

[0028] With the above structural setup, the coolant is initially filtered by the first filter screen 33 and then flows through the second filter screen 53. The second filter screen 53, with a larger mesh size, performs a more detailed and thorough secondary filtration, thereby improving the overall filtration effect and purification level.

[0029] Reference Figure 1-3The box 1 is provided with an inclined plate 10, and the lower end of the inclined plate 10 abuts against one side surface of the fixed plate 41.

[0030] By changing the slope of the bottom of the housing 1 through the above structural design, it is ensured that the coolant completely passes through the second filter element 5.
