Description

Technical Field

[0001] This utility model belongs to the field of machine tool equipment technology, and specifically relates to a CNC machine tool coolant recovery device. Background Technology

[0002] Machine tool coolant is a functional liquid used in metal cutting, grinding, and other machining processes. It is not an optional consumable, but rather an essential component of the machining process. Proper selection and use of coolant can comprehensively improve machining efficiency, tool life, workpiece quality, and equipment maintenance costs, and its role is becoming increasingly crucial, especially with the trend towards automation and high-precision machining.

[0003] During CNC machine tool operation, the friction between the cutting tool and the workpiece generates a large amount of iron filings that mix into the coolant, along with dust and solid particulate contaminants. Therefore, the coolant cannot be directly recycled after being collected in the coolant tank and requires further treatment. Existing coolant recovery devices filter the coolant before recycling. These devices typically use screens to filter the coolant, but the direct impact of the coolant on the screens reduces filtration efficiency and shortens their lifespan. Furthermore, replacing the filter media is inconvenient, requiring disassembly of the equipment.

[0004] Therefore, the above-mentioned problems are technical issues that urgently need to be addressed. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, this utility model provides a CNC machine tool coolant recovery device, aiming to solve the aforementioned technical problems. It offers good filtration effect, convenient maintenance, and high adaptability.

[0006] Technical solution: To achieve the above objectives, this utility model provides a CNC machine tool coolant recovery device, comprising: a machine tool coolant collection tank, a filter tank, a storage tank, and a filter. The machine tool coolant collection tank is connected to the filter tank, the filter tank is connected to the storage tank, the storage tank is connected to the filter, and the filter is connected to the machine tool coolant nozzle. The filter canister includes an outer shell, an inner cavity disposed within the outer shell, a filter element disposed within the inner cavity, and a lead screw. The lead screw is threaded onto the top of the outer shell, and the lower part of the lead screw is connected to the filter element. The filter element is a mesh bag type filter element. The liquid storage tank is equipped with a filter plate, which is inserted into the liquid storage tank through a slot.

[0007] The coolant is filtered through a filter tank, filter plate, and filter before entering the CNC machine tool for reuse, which improves the filtration effect. At the same time, the filter element can be lifted for replacement by turning the screw, and the filter plate can also be pulled out directly for easy cleaning and replacement.

[0008] Furthermore, the upper part of the inner cavity is provided with a hollow flange, the edge of the hollow flange is sealed to the inner wall of the outer shell, the hollow part of the hollow flange has the same diameter as the inner cavity and communicates with it, and the bottom of the inner cavity communicates with the chamber formed by the outer shell.

[0009] Furthermore, the upper part of the outer casing is provided with a liquid inlet, and the lower part with a liquid outlet. The liquid inlet is positioned higher than the hollow flange, and the liquid outlet is connected to the storage tank. After entering the filter tank, the coolant can only enter the inner cavity due to the action of the hollow flange. After passing through the filter element in the inner cavity, it flows out from the bottom and enters the storage tank through the liquid outlet.

[0010] Furthermore, the filter tank has a top cover, and the lead screw is threadedly connected to the top cover. The bottom of the filter tank has a drain port with a valve. The filter element can be removed for maintenance by opening the top cover, and sediment generated during long-term use of the filter tank can be discharged through the drain port.

[0011] Furthermore, the upper part of the storage tank is equipped with a movable cover, and the interior of the storage tank is also equipped with a set of liquid level sensors at different heights. The upper part of the filter plate is equipped with a set of handles. The liquid level sensors can monitor the liquid level in the storage tank, and the handles on the filter plate make it easy to pull out.

[0012] Furthermore, the machine tool coolant collection tank is equipped with a first pump, which is connected to a filter tank via a pipe, and the storage tank is equipped with a second pump, which is connected to a filter via a pipe.

[0013] Furthermore, it also includes a mobile trolley, on which the filter tank, storage tank, and filter are all mounted. The mobile trolley is equipped with a control box for controlling the first and second pumps. The mobile trolley enables the entire filtration and recovery unit to be mobile, allowing it to be moved within the site and adapted to different types of machine tools.

[0014] Furthermore, the filter is a single-core filter.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1) This utility model provides a CNC machine tool coolant recovery device, which effectively filters impurities in the coolant through triple filtration of a filter tank, a storage tank, and a filter. The filter element in the filter tank is mounted via a lead screw; rotating the lead screw allows the filter element to be lifted. The filter plate in the storage tank can be directly pulled out, facilitating maintenance of consumable filter media. 2) The filter tank is equipped with an inner cavity and a hollow flange. The hollow flange allows all the coolant to enter the inner cavity containing the filter element, ensuring filtration efficiency while preventing direct impact of the coolant on the filter element, which could affect filtration effectiveness and reduce its lifespan. 3) The filter tank, storage tank, and filter in this utility model are mounted on a mobile trolley, enabling efficient transfer of the device. Furthermore, this device is compatible with most machine tool equipment, exhibiting high adaptability. Attached Figure Description

Detailed Implementation

[0018] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] Example 1: like Figure 1-4As shown: A CNC machine tool coolant recovery device includes: a machine tool coolant collection tank 1, a filter tank 2, a storage tank 3, and a filter 4. The machine tool coolant collection tank 1 is connected to the filter tank 2, the filter tank 2 is connected to the storage tank 3, the storage tank 3 is connected to the filter 4, and the filter 4 is connected to the machine tool coolant nozzle. After passing through the nozzle, the machine tool coolant is collected by the machine tool coolant collection tank 1, and then sequentially processed through the filter tank 2, the storage tank 3, and the filter 4 before being pumped back to the nozzle, forming a cycle. The filter tank 2 includes an outer shell 21, an inner cavity 22 disposed within the outer shell, a filter element 23 disposed within the inner cavity 22, and a lead screw 24. The lead screw 24 is threaded onto the top of the outer shell 21, and the lower part of the lead screw 24 is connected to the filter element 23. The filter element 23 is a mesh bag type filter element. When the coolant passes through the filter tank 2, it first enters the inner cavity 22, is filtered by the filter element 23, and then flows out of the inner cavity 22 before flowing into the storage tank 3. To replace the filter element 23, simply rotate the lead screw 24 to lift the filter element 23. The liquid storage tank 3 is equipped with a filter plate 31, which is inserted into the liquid storage tank 3 through a slot.

[0020] The inner cavity 22 is provided with a hollow flange 221 at its upper part. The edge of the hollow flange 221 is sealed to the inner wall of the outer shell 21. The hollow part of the hollow flange 221 has the same diameter as the inner cavity 22 and communicates with it. The bottom of the inner cavity 22 is connected to the chamber formed by the outer shell 21.

[0021] The upper part of the outer casing 21 is provided with a liquid inlet 25 and the lower part is provided with a liquid outlet 26. The position of the liquid inlet 25 is higher than that of the hollow flange 221, and the liquid outlet 26 is connected to the liquid storage tank 3.

[0022] Hollow flange 221 seals the upper part of the inner cavity of housing 21, so that after the coolant enters housing 21, it can only flow into inner cavity 22, preventing the coolant from flowing out directly through outlet 26 without filtration. The coolant flows in from the inlet 25 located on the side, and after being buffered by the inner wall of housing 21 and hollow flange 221, the coolant flows from the top to filter element 23, avoiding direct impact on the filter element. At the same time, since the filter element is a mesh bag filter element, after the coolant flows in, the mesh bag expands evenly due to the impact of the liquid, so that the liquid material is evenly distributed on the entire inner surface of the filter mesh bag. The liquid that passes through the filter mesh bag flows from the bottom of inner cavity 22 into inner cavity of housing 21, and finally flows out from outlet 26.

[0023] Specifically, the filter tank 2 has a top cover 27, and the lead screw 24 is threadedly connected to the top cover 27. The bottom of the filter tank 2 has a drain port 28, and the drain port 28 is equipped with a valve. In this embodiment, the top of the lead screw 24 is equipped with a handwheel. When it is necessary to clean or replace the filter element 23, turning the handwheel drives the lead screw 24 to rotate, causing the lead screw 24 to lift the filter element 23. Then, the top cover 27 can be opened to remove the filter element 23.

[0024] In addition, the upper part of the liquid storage tank 3 is provided with a movable cover plate 32, and the interior of the liquid storage tank 3 is also provided with a set of liquid level sensors 33 at different heights. The upper part of the filter plate 31 is provided with a set of handles 311. By opening the movable cover plate 32 and pulling the handles 311, the filter plate 31 can be pulled out from its mounting slot.

[0025] Specifically, the machine tool coolant collection tank 1 is equipped with a first pump 11, which is connected to the filter tank 2 through a pipe, and the storage tank 3 is equipped with a second pump 34, which is connected to the filter 4 through a pipe.

[0026] In addition, a mobile trolley 5 is included. The filter tank 2, the storage tank 3, and the filter 4 are all mounted on the mobile trolley 5. The mobile trolley 5 is equipped with a control box 51 for controlling the first pump 11 and the second pump 34. The mobile trolley 5 gives it extremely high mobility, allowing for efficient transfer within the site. At the same time, this device is compatible with most machine tools. Simply connect the inlet 25 of the filter tank 2 to the machine tool's built-in coolant collection tank, and connect one end of the filter 4 to the machine tool's cooling nozzle to achieve coolant recovery and recycling.

[0027] In a preferred embodiment, the filter 4 is a single-core filter.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
