The bent channel has an inlet and an outlet that are opposite to each other. The inlet of the bent channel is close to the overflow plate, and the outlet of the bent channel is close to the filter plate. The distance that the liquid travels from the inlet to the outlet through the bent channel is greater than the straight distance from the inlet to the outlet.

[0007] In some feasible implementations, a mounting base is provided inside the box, and the overflow plate is detachably mounted on the mounting base; The height of the top of the overflow plate is lower than the height of the top of the tank; and / or the overflow plate is provided with an overflow hole connecting the water receiving chamber and the sedimentation chamber.

[0008] In some feasible implementations, the housing includes a first side plate and a second side plate disposed opposite to each other, the first side plate being provided with a first slot and the second side plate being provided with a second slot, and the two sides of the filter plate being detachably inserted into the first slot and the second slot.

[0010] In some feasible embodiments, a flow guide is also included that covers the top of the housing. The flow guide is inclined and has a high position and a low position, with the low position of the flow guide located above the water receiving cavity.

[0011] In some feasible implementations, the water receiving cavity is located in the middle of the box, and there are two sedimentation cavities and two water storage cavities. The two sedimentation cavities are located on both sides of the water receiving cavity, and each water storage cavity is located on the side of the corresponding sedimentation cavity away from the water receiving cavity. The flow guide includes two components, which slope downwards from both ends of the housing towards the middle of the housing.

[0012] In some feasible implementations, the system further includes a first filter element disposed on the top of the housing and at least one second filter element located above the first filter element, wherein the first filter element is detachably disposed above the housing and located above the flow guide, and the second filter element is detachably installed on the first filter element and located inside the first filter element.

[0025] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0026] Machine tool water tanks are precision subsystems integrating filtration, temperature control, and liquid supply. However, existing machine tool water tanks have poor filtration performance, and the continuous accumulation of impurities can clog the water pump, causing water supply interruptions.

[0027] To solve the above technical problems and improve the filtration effect of the machine tool water tank, please refer to... Figure 1 This utility model provides a machine tool water tank, including a tank body 100 with a chamber Q. In this embodiment, both the tank body 100 and the chamber Q are rectangular. In some other embodiments, the shapes of the tank body 100 and the chamber Q can be cube, cylinder or sphere, as long as they can hold liquid and do not leak.

[0028] To enable the machine tool water tank to achieve staged filtration and improve the filtration effect, the machine tool water tank also includes an overflow plate 200, a filter plate 300, and a bent guide component 400. The chamber Q includes a water receiving chamber Q1, a sedimentation chamber Q2, and a water storage chamber Q3. The overflow plate 200 is located between the water receiving chamber Q1 and the sedimentation chamber Q2, separating the water receiving chamber Q1 from the sedimentation chamber Q2. The filter plate 300 is located between the sedimentation chamber Q2 and the water storage chamber Q3, separating the sedimentation chamber Q2 from the water storage chamber Q3.

[0029] To facilitate the initial flow of liquid entering the tank 100 into the water receiving cavity Q1, the machine tool water tank also includes a flow guide 130 covering the top of the tank 100. The flow guide 130 is inclined and has a high position and a low position, with the low position of the flow guide 130 located above the water receiving cavity Q1. For example, there can be two flow guides 130, which are arranged opposite each other with a gap, and the water receiving cavity Q1 is located above the gap.

[0030] To improve the filtration effect of the machine tool water tank, sedimentation chambers Q2 and water storage chambers Q3 are provided on both sides of the water receiving chamber Q1. Specifically, the water receiving chamber Q1 is located in the middle of the tank body 100, and there are two sedimentation chambers Q2 and two water storage chambers Q3. The two sedimentation chambers Q2 are located on both sides of the water receiving chamber Q1, and each water storage chamber Q3 is located on the side of the corresponding sedimentation chamber Q2 away from the water receiving chamber Q1. The flow guide 130 also includes two components, which are inclined downward from both ends of the tank body 100 toward the middle of the tank body 100, thereby improving the filtration effect.

[0031] To facilitate the extraction of filtered liquid from the water storage chamber Q3 and provide clean liquid for the machine tool, the machine tool water tank also includes a pump body 800. The pump body 800 includes a mounting part and a suction part. The mounting part is fixed to the housing 100, and the suction part extends into the water storage chamber Q3.

[0032] To improve the liquid flow path within the settling chamber Q2 and enhance its settling effect, allowing more chips to settle within Q2 and preventing them from flowing into the water storage chamber Q3, a bent guide member 400 is disposed within the settling chamber Q2. The settling chamber Q2 forms a bent channel through the bent guide member 400, and this bent channel has opposite inlets (see [reference]). Figure 1 (The starting position of the dashed line bend) and the exit (please refer to) Figure 1 (The end position of the dashed bend line), the inlet of the bend channel is close to the overflow plate 200, the outlet of the bend channel is close to the filter plate 300, and the distance the liquid travels from the inlet to the outlet through the bend channel is greater than the straight distance from the inlet to the outlet.

[0033] The bent flow guide 400 is a labyrinth-shaped structure with at least one communicating channel. The labyrinth-shaped structure forms multiple bent channels by adding serpentine baffles, thereby maximizing the liquid flow path within the fixed-area sedimentation chamber Q2. The following describes a structural example of the bent flow guide 400. The bent flow guide 400 includes a first flow guide plate 410 and a second flow guide plate 420. The first flow guide plate 410 and the second flow guide plate 420 are spaced apart. The first flow guide plate 410 is fixedly connected to the first side plate 110, and a first notch K1 exists between the first flow guide plate 410 and the second side plate 120. The second flow guide plate 420 is fixedly connected to the second side plate 120, and a second notch K2 exists between the second flow guide plate 420 and the first side plate 110. The first flow guide plate 410, the second flow guide plate 420, the first notch K1, and the second notch K2 divide the sedimentation chamber Q2 into bent channels (see reference). Figure 1 (Middle dashed line with bends).

[0034] To improve the ease and stability of installation between the overflow plate 200 and the housing 100, a mounting base 101 is provided inside the housing 100, and the overflow plate 200 is detachably installed on the mounting base 101. In this embodiment, the mounting base 101 extends vertically and has a bent structure, such as a right-angle structure, which facilitates the vertical connection of the mounting base 101 with the housing 100 and the overflow plate 200. For example, the two long strip right-angled sides of the mounting base 101 are fixedly connected to the housing 100 and the overflow plate 200 by bolts.

[0035] To improve the flow path of liquid in the water receiving cavity Q1 through the overflow plate 200 to the sedimentation cavity Q2, thereby enhancing the flexibility of liquid flow within the tank 100, the top of the overflow plate 200 is lower than the top of the tank 100. This allows the liquid in the water receiving cavity Q1 to overflow the top of the overflow plate 200 before entering the sedimentation cavity Q2. Alternatively, the overflow plate 200 is provided with an overflow hole 210 connecting the water receiving cavity Q1 and the sedimentation cavity Q2. The liquid in the water receiving cavity Q1 only needs to reach the height of the overflow hole 210. The height of the overflow plate 200 can be higher than, equal to, or lower than the height of the tank 100. The overflow hole 210 is far away from the first notch K1 or the second notch K2. This way, when the liquid in the water receiving chamber Q1 reaches the sedimentation chamber Q2 through the overflow hole 210, it will flow to the first half of the sedimentation chamber Q2 (that is, the inlet of the bend channel), preventing the liquid through the overflow hole 210 from flowing directly to the second half of the sedimentation chamber Q2 (that is, the outlet of the bend channel) through the first notch K1 or the second notch K2, thus ensuring the filtration effect in the sedimentation chamber Q2.

[0036] To improve the ease and stability of installation between the filter plate 300 and the housing 100, the housing 100 includes a first side plate 110 and a second side plate 120 arranged opposite each other. The first side plate 110 has a first slot 111, and the second side plate 120 has a second slot 121. Both sides of the filter plate 300 are detachably inserted into the first slot 111 and the second slot 121. For example, both the first slot 111 and the second slot 121 extend vertically, and the cross-sections of both slots are U-shaped. The opening of the first slot 111 faces the opening of the second slot 121, facilitating the insertion of the filter plate 300 into the first slot 111 and the second slot 121. It is understood that the shapes of the first slot 111 and the second slot 121 can be adjusted according to actual conditions, as long as they can cooperate to insert the filter plate 300 into the housing 100.

[0037] To improve the filtration effect of the machine tool water tank and minimize the amount of chips entering the water receiving chamber Q1, the machine tool water tank also includes a first filter element 500 disposed on the top of the tank body 100 and at least one second filter element 600 located above the first filter element 500. The first filter element 500 is detachably disposed on the top of the tank body 100 and located above the flow guide 130, and the second filter element 600 is detachably installed on the first filter element 500 and located inside the first filter element 500. The second filter element 600 can be a coarse filter, and the first filter element 500 can be a fine filter. For example, the aperture of the sieve holes on the second filter element 600 is larger than the aperture of the first filter element 500. In this way, when the liquid first passes through the coarse filtration of the second filter element 600 and then through the fine filtration of the first filter element 500, staged filtration is achieved.

[0038] To facilitate the movement of the machine tool water tank, a plurality of rollers 700 are provided on the outer periphery of the tank body 100, and the bottom height of each roller 700 is lower than the bottom height of the tank body 100. For example, the rollers 700 are mounted on the bottom of the outer periphery of the tank body 100 via a base, and the rollers 700 support the tank body 100, thereby facilitating the movement of the tank body 100.

[0039] To improve the filtration effect of the machine tool housing 100, when the workpiece processed by the machine tool is an iron product, a magnetic attraction device is provided at the bottom of the machine tool water tank. The magnetic attraction device can be an electromagnet. When the electromagnet is energized, it has magnetism, which facilitates the attraction of iron filings. When the electromagnet is de-energized, its magnetism disappears, which facilitates the collection of iron filings attracted when it is energized.

[0040] The aforementioned machine tool water tank includes a tank body 100 with a chamber Q, and further includes an overflow plate 200, a filter plate 300, and a bent guide component 400. The chamber Q includes a water receiving chamber Q1, a sedimentation chamber Q2, and a water storage chamber Q3. The overflow plate 200 is located between the water receiving chamber Q1 and the sedimentation chamber Q2, and the filter plate 300 is located between the sedimentation chamber Q2 and the water storage chamber Q3. The bent guide component 400 is disposed within the sedimentation chamber Q2, and the sedimentation chamber Q2 forms a bent channel through the bent guide component 400. The bent channel has an inlet and an outlet that are opposite to each other. The inlet of the bent channel is close to the overflow plate 200, and the outlet of the bent channel is close to the filter plate 300. The distance that the liquid travels from the inlet to the outlet through the bent channel is greater than the straight-line distance from the inlet to the outlet.

[0041] As the liquid inside the water receiving chamber Q1 accumulates, it flows through the overflow plate 200 into the sedimentation chamber Q2 when it reaches the preset height. This way, a certain volume of liquid is retained in the water receiving chamber Q1, and some of the chips also remain in the water receiving chamber Q1 along with this liquid. This reduces the possibility of some chips flowing into the sedimentation chamber Q2 and the water storage chamber Q3, thereby improving the filtration effect of the machine tool water tank.

[0042] A second aspect of the present invention provides a machine tool, including a base and the aforementioned machine tool water tank, wherein the machine tool water tank is fixed relative to the base.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0044] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
