Description

Technical Field

[0001] This utility model relates to the technical field of machine tool filtration equipment, and in particular to circulating filtration water tanks. Background Technology

[0002] Machine tools require cutting fluid or cleaning fluid during processing. Generally, cutting fluid or cleaning fluid needs to be recycled and reused; otherwise, it will cost more. In some application scenarios, high water pressure is also required.

[0003] Chinese Utility Model Patent Application No. 202223410092.X discloses a cutting fluid waste recovery device. This device includes a base plate, with fixed columns fixedly installed at the four corners of the top of the base plate. A top plate is fixedly installed at the top of the four fixed columns, and a filter box is fixedly installed at the top of the top plate. The filter box contains a primary filter plate, a secondary filter plate, and a tertiary filter plate. This utility model facilitates multi-stage filtration of the cutting fluid through the primary, secondary, and tertiary filter plates installed inside the filter box. The filtered cutting fluid flows into the filter cylinder, where it permeates through the permeating cotton filled inside. Simultaneously, a drive motor rotates the filter cylinder, centrifugally ejecting the permeated cutting fluid, effectively improving the cutting fluid recovery process while ensuring the treatment effect and preventing the recovered cutting fluid from containing micro-metal fragments that could affect its use.

[0004] The aforementioned existing technologies are simple and crude, many functions have not been considered, there is a lot of waste, they cannot meet the standards for reuse, they are not environmentally friendly, and the filter structure is inconvenient to remove, replace or clean.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. When the number of elements is referred to as "multiple," it can be any number of two or more. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0027] like Figure 1-3As shown, this embodiment provides a circulating filtration water tank, including a primary water tank 1 and a secondary water tank 2. The primary water tank 1 is equipped with an oil-water separator 3. Both the primary water tank 1 and the secondary water tank 2 are equipped with a primary filter tank 5 and a secondary filter tank 6, respectively. A high-pressure water pump 8 is located below the water tanks, and the water inlet 10 of the secondary water tank 2 is connected to the high-pressure water pump 8. The water flowing from the machine tool flows sequentially through the primary water tank 1 and the secondary water tank 2 before flowing into the high-pressure water pump 8. The water is filtered first by the filter tanks in each water tank before flowing into the main water tank. The two-stage design allows for the stratified filtration of waste particles of different sizes, improving filtration efficiency.

[0028] In this embodiment, a primary filter tank 5 is inserted into a primary water tank 1. The inlet of the primary filter tank 5 is connected to the outlet of the machine tool. After being filtered by the filter tank, the water flows into the primary water tank 1. An oil-water separator 3 is arranged on one side of the primary filter tank 5. A collection box 12 is also fixedly installed on the primary water tank 1. The oil outlet of the oil-water separator 3 is located above the collection box 12, which is used to collect the oil separated by the oil-water separator 3. Specifically, the oil-water separator 3 includes a belt 16 and an oil guide plate 11. The oil-water separator 3 has a rotating drive wheel and a driven wheel. The belt 16 covers the drive wheel and the driven wheel. The oil-water separator 3 is equipped with a motor, which can control the rotation of the drive wheel. The rotation of the drive wheel can control the movement of the belt 16. The oil guide plate 11 is inclinedly mounted above the collection box 12. One end of the oil guide plate 11 abuts against the belt 16. The position of the oil guide plate 11 is fixed. As the belt 16 moves continuously, the oil guide plate 11 can hang the grease on the belt 16 and let it flow into the collection box 12 under the action of gravity.

[0029] In this embodiment, water level gauges 4 are installed in both the primary water tank 1 and the secondary water tank 2. The water level gauges 4 are used to observe the water level in the primary water tank 1 and the secondary water tank 2, so that users can observe the internal water level and determine whether the filter tank or pipeline is blocked and needs to be replaced.

[0030] The primary water tank 1 is equipped with a water pump 7, which is responsible for pumping water from the primary water tank 1 into the secondary water tank 2. The inlet of the water pump 7 extends into the primary water tank 1, and the outlet of the water pump 7 is connected to the inlet of the secondary filter tank 6. After being filtered by the filter tank, the water flows into the secondary water tank 2.

[0031] In this embodiment, a heating rod 9 for heating the water in the secondary water tank 2 is inserted inside the secondary water tank 2. The secondary water tank 2 has a water inlet 10, which is located on one side of the heating rod 9. In actual use, it may be necessary to control the water temperature, so the water is heated before it is fed into the high-pressure water pump 8 from the secondary water tank 2. The secondary water tank 2 is also equipped with a high-pressure switching valve 14 and an electromagnetic control valve 15. The high-pressure switching valve 14 is used to switch between water output from the nozzle and water inlet in the water tank; the electromagnetic control valve 15 mainly controls the water pump 7 inside the machine.

[0032] The secondary water tank 2 is equipped with an overflow port 13, which is located at the top of the secondary water tank 2. The overflow port 13 is connected to one end of the primary water tank 1. When the water level in the secondary water tank 2 is too high, it will naturally flow back into the primary water tank 1.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
