Their essence is still based on sedimentation filtration treatment. When the coolant flow rate is large, it is easy to re-impact the settled filter residue, resulting in low filtration efficiency and effect, which is not conducive to efficient coolant filtration treatment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0030] The following is combined with Figure 1 This application is described in further detail.

[0031] The embodiment of the present application discloses a metal processing coolant filter tank. Figure 1 The metal processing coolant filter tank includes a collection tank 1, the top of the collection tank 1 is provided with an opening, the top of one side of the collection tank 1 is provided with a liquid inlet pipe 11, and the bottom of the other side of the collection tank 1 is provided with a liquid discharge pipe 12. At least two groups of filter units 2 are provided in the collection tank 1, and the adjacent filter units 2 are arranged at intervals to divide the internal space of the collection tank 1 into multiple filter chambers. The filter unit 2 is used to allow coolant to pass through and block solid debris in the coolant in the filter chamber in front. The filter unit 2 is vertically detachable and plugged into the collection tank 1.

[0032] A plurality of baffles 4 are provided on the top of the inner wall of the collection tank 1 , and a plug-in slot is formed between two adjacent baffles 4 , and the filter unit 2 is inserted into the collection tank 1 through the plug-in slot.

[0033] The beneficial technical effects of the metalworking coolant filter tank of the embodiment of the present application are roughly as follows:

[0034] When the coolant enters the first filter chamber from the liquid inlet pipe 11 at high speed, multiple groups of filter units 2 will gradually block the solid debris in the coolant in the corresponding filter chamber. Different from the traditional precipitation treatment method, even if the coolant impacts the filter residue again, due to the blocking effect of the filter unit 2, the filter residue of the corresponding particle size will never be able to pass through the corresponding filter unit 2 smoothly, thereby significantly improving the efficiency and effect of the filtration, which is conducive to efficient coolant filtration treatment. In addition, the overall structure is simple, the production cost is relatively low, and it is convenient to disassemble the filter unit 2 for cleaning.

[0035] In order to ensure that more filter residue can be stored in each filter chamber, the spacing between adjacent filter units 2 is between 30-60 cm (the preferred spacing is 50 cm), and the number of filter units 2 can be between 3-6 groups, so as to control the production cost and ensure the filtering effect. In this embodiment, the number of filter units 2 is preferably 3 groups.

[0036] In this embodiment, the filter unit 2 includes a first mesh plate 21, a second mesh plate 22 and a filter sponge 23. The filter sponge 23 is sandwiched between the first mesh plate 21 and the second mesh plate 22. The filter sponge 23 is provided with holes 231 for increasing the flow rate of the coolant, and the first mesh plate 21 and the second mesh plate 22 are stainless steel mesh plates.

[0037] The diameters of the holes 231 on adjacent filter sponges 23 gradually decrease, with the holes 231 on the filter sponge 23 closest to the inlet pipe 11 having the largest diameter and the holes 231 on the filter sponge 23 closest to the drain pipe 12 having the smallest diameter. By controlling the size of the holes 231, the coolant's retention time within the corresponding filter chamber can be controlled, indirectly affecting the extent to which the coolant is filtered by the filter assembly. Furthermore, the closer the coolant is to the drain pipe 12, the more difficult it is for the coolant to pass through the filter assembly, resulting in a more thorough filtration effect.

[0038] The filter unit 2 designed above has a simple structure, is easy to manufacture, and has a better filtering effect on the coolant.

[0039] In this embodiment, in order to facilitate the staff to disassemble and install the filter unit 2, the filter unit 2 also includes a handle 24, which is installed on the top of the first mesh plate 21 and / or the second mesh plate 22, and the handle 24 is L-shaped.

[0040] In this embodiment, in order to improve the stability of the filter unit 2 in the collection tank 1, the filter unit 2 also includes a magnetic bottom plate 25, which is connected between the bottom of the first mesh plate 21 and the bottom of the second mesh plate 22. The inner bottom wall of the collection tank 1 is provided with a magnet bar 3, which is used to magnetically fix the magnetic bottom plate 25.

[0041] In order to ensure the flatness of the inner bottom wall of the collection tank 1, so that the staff can quickly clean the filter residue accumulated on the inner bottom wall of the collection tank 1 after all the filter units 2 are removed, the inner bottom wall of the collection tank 1 is provided with a groove 13, and the magnet bar 3 is embedded in the groove 13, and the upper surface of the magnet bar 3 is flush with the inner bottom wall of the collection tank 1.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
