Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more specifically, to a water tank for a CNC turning device. Background Technology

[0002] In CNC turning, the CNC turning machine generates a large amount of iron filings during operation. Simultaneously, to cool and lubricate the cutting tools and workpiece, cutting fluid (usually water-based or oil-based) needs to be continuously sprayed. This used cutting fluid mixes with the iron filings to form waste liquid. Direct discharge of this waste liquid not only wastes resources but also pollutes the environment. Therefore, how to effectively separate iron filings from the cutting fluid and achieve the recycling of the cutting fluid has become a critical problem that urgently needs to be solved in CNC turning.

[0003] Traditional water tanks often rely on a single filter or simple sedimentation to separate iron filings, which is insufficient for effectively separating iron filings of different sizes. This is especially true for tiny iron filings, where the separation is even less effective, resulting in a large amount of iron filings remaining in the cutting fluid, affecting the quality of the cutting fluid's reuse and machining accuracy.

[0004] When iron filings accumulate to a certain level inside the water tank, the machine needs to be stopped for cleaning. However, traditional water tank cleaning methods mostly involve manual operation inside the tank, which is limited by factors such as the tank's location and the working environment, resulting in low cleaning efficiency and being time-consuming and labor-intensive. In addition, the cleaning process can easily cause cutting fluid to splash out, polluting the working environment.

[0005] Incomplete separation of metal filings can easily clog pipes and nozzles during the cutting fluid circulation process, affecting the normal supply of cutting fluid and its cooling and lubrication effects. Furthermore, residual metal filings can accelerate the deterioration of the cutting fluid, shorten its service life, and increase operating costs. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a water tank for a CNC turning device. By incorporating a coarse filtration unit, a separation unit, and a circulating water unit, it achieves efficient separation of iron filings and cutting fluid, and enables the recycling of the cutting fluid. Furthermore, by optimizing the structural design of the separation unit, such as using a detachable housing and graded baffles, it improves cleaning efficiency and separation effect, while reducing energy consumption and maintenance costs.

[0007] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0008] The present invention discloses a water tank for a CNC turning device, comprising a tank body, wherein a coarse filtration unit, a separation unit, and a circulating water unit are provided on the tank body. The coarse filtration unit, the separation unit, and the circulating water unit are connected in sequence. The separation unit includes an inlet, an outlet, and a baffle structure. The inlet is connected to the coarse filtration unit, and the outlet is connected to the circulating water unit. The baffle structure includes multiple baffles spaced apart along the water flow direction. Through the multiple baffles, iron filings are blocked and retained, while water overflows the baffles and continues to flow, gradually separating the iron filings and water in stages to achieve complete separation of water and iron filings.

[0009] Preferably, the multiple baffles are arranged in a structural form with different heights.

[0010] Preferably, the separation unit includes a box body, the water tank includes a second collection tank, the box body is fitted into the second collection tank, and the baffle structure is located inside the box body, so that the deposited iron filings can be cleaned by replacing the box body.

[0011] Preferably, the second collection tank is provided with filter baffles corresponding to the inlet and outlet respectively; or, the box body is provided with filter baffles corresponding to the inlet and outlet respectively.

[0012] Preferably, the box body includes a drainage base plate.

[0013] Preferably, the box body is provided with a second handle.

[0014] Preferably, the box body may be provided with a cover.

[0015] Preferably, the baffle structure is located directly inside the water tank.

[0016] Preferably, the water tank has a first handle on its side wall.

[0017] Preferably, the water tank is provided with a drain outlet.

[0018] Preferably, the coarse filtration unit includes a first collection tank and a filter frame.

[0019] Preferably, the circulating water unit includes a circulating water pump.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] This invention incorporates multiple baffles, which can be configured at different heights. Increasing the baffle height near the inlet effectively deposits larger, more easily deposited iron filings; decreasing the baffle height near the outlet allows for the deposition of smaller iron filings while reducing water flow resistance and energy consumption. Alternatively, a structure with a higher center and lower sides can be adapted to water flow and turbulence conditions, further enhancing iron filings separation. The baffle height is optimized based on water flow direction and iron filings deposition characteristics, avoiding excessively high baffles that increase water flow resistance, thus reducing energy consumption and achieving effective iron filings separation while rationally controlling energy consumption.

[0022] Based on this, the separator structure of the separation unit is set on the box body, which is fitted into the collection tank. When a large amount of iron filings accumulates and needs to be cleaned, the operator can directly remove the box body and quickly replace it with a spare box body, without delaying the operation of the water tank, greatly improving cleaning efficiency and reducing downtime.

[0023] In addition, through multi-stage separation of the coarse filtration unit and the separation unit, iron filings in the cutting fluid are effectively removed, ensuring that the water entering the circulating water unit meets the standards for continued use, thus guaranteeing the quality of the circulating cutting fluid and improving the machining accuracy and tool life of the CNC turning device.

[0024] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0032] The present invention will be further explained and described below through specific embodiments. It should be understood that the purpose of the following embodiments is to make the technical solution of the present invention clearer and easier to understand, and does not limit the scope of protection of the claims.

[0033] The present invention will be further described below through specific embodiments.

[0034] Example

[0035] This embodiment provides a water tank for a CNC turning device, such as... Figure 1 , 2 As shown, the device includes a housing 10 for collecting iron filings and water from a CNC turning device. The housing 10 is equipped with a coarse filtration unit, a separation unit, and a circulating water unit, which are connected in sequence. The coarse filtration unit is used to initially separate the iron filings flowing out with water, separating larger iron filings, while smaller iron filings continue to enter the separation unit with the water flow. The separation unit is used to further separate the iron filings and water to ensure that the water can continue to enter the circulating water unit. The circulating water unit is used to reuse the separated water and return it to the CNC turning device.

[0036] Specifically, the separation unit includes a box body 20, the water tank includes a second collection tank 11, the box body 20 is fitted into the second collection tank 11, the box body 20 includes a water inlet 21, a water outlet 22, a baffle structure, and a drainage bottom plate 24, the water inlet 21 is connected to the coarse filtration unit, the water outlet 22 is connected to the circulating water unit, the baffle structure includes multiple baffles 23 spaced apart along the water flow direction, iron filings are blocked by the baffles 23 and left behind, water overflows the baffles 23 and continues to flow, through multiple baffles 23, the iron filings and water are separated in stages and gradually, to achieve the effect of thorough separation;

[0037] It should be noted that the baffle structure can also be directly installed on the second collection tank 11. The purpose of installing the baffle structure on the box 20 is that when a large amount of iron filings accumulates and needs to be cleaned, the operator can directly remove the box 20 and quickly replace it with another spare box 20 without delaying the operation of the water tank. If the baffle structure is directly installed on the second collection tank 11, the operator needs to clean the iron filings in the water tank. Due to the influence of the working environment and the location of the water tank, the efficiency is low and it is time-consuming and laborious. However, this does not mean that the baffle structure cannot be directly installed in the water tank. In this way, two boxes 20 with baffle structures are prepared. When one box 20 is in use, the iron filings in the other box 20 can be cleaned. This cycle can be repeated to improve the usage effect and cleaning efficiency.

[0038] In addition, the function of the drainage base plate 24 is to drain water when the box 20 needs to be removed to clean iron filings, thereby reducing the weight of lifting.

[0039] More specifically, the multiple baffles 23 can be configured as multiple baffles 23 of different heights. Because near the inlet, larger iron filings are more likely to settle due to their greater mass, while smaller iron filings are more likely to be carried by the water flow and overflow the baffles 23, the height of the baffles 23 near the inlet can be appropriately increased. However, excessively high baffle heights 23 increase water flow resistance and energy consumption. Therefore, near the outlet 22, which is where smaller iron filings are concentrated, the height of the baffles 23 can be lowered, which can simultaneously settle iron filings and reduce resistance and energy consumption. Alternatively, a structure with a higher height in the middle and lower heights on both sides can be configured, and the specific configuration can be adaptively adjusted according to the water flow rate and turbulence conditions.

[0040] More specifically, the second collection tank 11 is provided with filter baffles 12 corresponding to the water inlet 21 and the water outlet 22, respectively. Alternatively, the filter baffles 12 can be directly installed on the water inlet 21 and the water outlet 22. The purpose of both is to separate water and iron filings.

[0041] More specifically, the box body 20 is provided with a second handle 25 to facilitate the removal of the box body 20.

[0042] More specifically, the box body 20 may be provided with a cover plate 26. The cover plate 26 can be opened to clean iron filings, and the cover plate 26 can be closed to prevent water from splashing out and to prevent external dust from entering and causing contamination.

[0043] Specifically, the water tank is provided with a first handle 13 on its side wall, which is used to move and position the water tank.

[0044] Specifically, the water tank is provided with a drain outlet 14, which is used to discharge some water when the water flow rate is large, so as to regulate the flow rate of the circulating water.

[0045] Specifically, the coarse filtration unit includes a first collection tank 31 and a filter frame 32. Water and iron filings discharged by the CNC turning device first enter the first collection tank 31 through the filter frame 32, and then enter the separation unit from the first collection tank 31.

[0046] Specifically, the circulating water unit includes a circulating water pump 41.

[0047] This utility model has been described through embodiments, but it does not constitute a limitation on this utility model. Other variations of the disclosed embodiments, which are readily apparent to those skilled in the art, should fall within the scope of the claims of this utility model, with reference to the description of this utility model.
