[0002] Metal cutting fluids are widely used in the machining and manufacturing industry. They play a role in cooling, lubrication, rust prevention and cleaning during the machining process. They are an indispensable industrial liquid in the machining process and a key factor in ensuring machining efficiency and workpiece quality.

[0003] During routine machining, cutting fluid often contains a large amount of debris, metal powder, and other impurities. These impurities not only affect the performance of the cutting fluid but may also damage the machine tool and workpiece. Furthermore, as machining continues, the temperature of the cutting fluid gradually rises. If it is not cooled in time, it will affect the cutting effect and the stability of the machine tool operation. Therefore, developing a circulation device that can effectively filter debris and cool the cutting fluid has high practical value. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] See Figure 1-2 As shown, a machine tool cutting fluid circulation device includes a base plate 1, on which a cutting fluid recovery tank 2, a plate-fin heat exchanger 3, a circulation pump 4, and a three-way solenoid valve 5 are disposed. A filter element 6 is disposed inside the cutting fluid recovery tank 2, dividing the tank into upper and lower chambers. An inlet is located in the upper chamber, and an outlet and a return outlet are located in the lower chamber. The inlet of the plate-fin heat exchanger 3 is connected to a heat exchanger-storage tank pipe 7. The outlet of the plate-fin heat exchanger 3 is connected to the outlet of the cutting fluid recovery tank 2, and the outlet of the plate-fin heat exchanger 3 is connected to the inlet of the circulating pump 4 through the heat exchanger-pump pipe 8. A fan cooling module 9 is provided on the side wall of the plate-fin heat exchanger 3 to accelerate its heat dissipation. The first port of the three-way solenoid valve 5 is connected to the outlet of the circulating pump 4 through the valve-pump pipe 10, and the second port of the three-way solenoid valve 5 is connected to the return port of the cutting fluid recovery tank 2 through the return pipe 11.

[0026] Furthermore, in this embodiment, the upper end of the upper chamber of the cutting fluid recovery tank 2 is detachably configured to form a cover 21. The cover 21 is provided with a folding handle 12, and a latch 13 is provided between the cover 21 and the outer wall of the cutting fluid recovery tank 2. The handle 12 facilitates the removal of the cover 21, while the latch 13 secures the installed cover 21 to the cutting fluid recovery tank 2. In this embodiment, a sealing strip (shown in the figure) is provided between the cover 21 and the cutting fluid recovery tank 2, and the fluid inlet of the cutting fluid recovery tank 2 is located on the cover 21.

[0027] Furthermore, in this embodiment, a liquid level sensor 14 is provided inside the lower chamber of the cutting fluid recovery tank 2; the liquid level sensor 14 includes a high liquid level switch and a low liquid level switch. During installation, the low liquid level switch is located at the lower end of the lower chamber, while the high liquid level switch is located at the upper end of the lower chamber, but the position of the high liquid level switch is lower than the return port of the cutting fluid recovery tank 2.

[0028] Furthermore, in this embodiment, a one-way valve 15 is provided at the inlet of the cutting fluid recovery tank 2. The one-way valve 15 is positioned such that the cutting fluid can flow into the upper chamber of the cutting fluid recovery tank 2 through the one-way valve 15, that is, the cutting fluid flowing into the upper chamber cannot flow out through the one-way valve 15.

[0029] Furthermore, in this embodiment, the heat exchanger-storage tank pipeline 7 is connected to the outlet of the cutting fluid recovery tank 2 via a manual three-way valve 16. Specifically, the first port of the manual three-way valve 16 is connected to the outlet of the cutting fluid recovery tank 2, the second port of the manual three-way valve 16 is connected to the heat exchanger-storage tank pipeline 7, and the third port of the manual three-way valve 16 is connected to an external pipeline. In operation, the first and second ports of the manual three-way valve 16 are kept connected.

[0030] Furthermore, in this embodiment, a temperature sensor 17 is provided at the liquid outlet of the plate-fin heat exchanger 3, and the temperature of the cutting fluid flowing out of the plate-fin heat exchanger 3 is monitored by the temperature sensor 17.

[0031] Furthermore, in this embodiment, the fan cooling module 9 consists of a fan 91 and a fan protective cover 92.

[0032] Furthermore, in this embodiment, the lower end of the substrate 1 is provided with a caster wheel 18 with support. The caster wheel 18 with support facilitates the movement of the device while also facilitating its fixation.

[0033] The working principle of this utility model is as follows:

[0034] Before use, connect the inlet of the one-way valve 15 to the outlet of the machine tool cutting fluid through a pipe, and connect the third port of the three-way solenoid valve 5 to the filling port of the machine tool cutting fluid through a pipe.

[0035] During use, the cutting fluid in the machine tool flows into the upper chamber of the cutting fluid recovery tank 2 through the one-way valve 15, and then flows into the lower chamber of the cutting fluid recovery tank 2 after being filtered by the filter element 6. At this time, the debris, metal powder and other impurities in the cutting fluid flowing into the lower chamber are filtered out by the filter element 6. The cutting fluid flowing into the lower chamber is then transported back into the machine tool for the next cycle under the action of the circulation pump 4, passing through the plate-fin heat exchanger 3, the circulation pump 4 and the three-way solenoid valve 5 in sequence.

[0036] When the cutting fluid enters the lower chamber of the cutting fluid recovery tank 2, the high level switch controls the circulation pump 4 to run when the fluid level is high, and the low level switch controls the circulation pump 4 to stop running when the fluid level is low.

[0037] Furthermore, when the temperature sensor 17 detects that the temperature of the cutting fluid flowing out of the outlet of the plate-fin heat exchanger 3 is lower than the set value, it controls the first and third ports of the three-way solenoid valve 5 to connect, so that the cutting fluid flows back into the machine tool; and when the temperature sensor 17 detects that the temperature of the cutting fluid flowing out of the outlet of the plate-fin heat exchanger 3 is higher than the set value, it controls the first and second ports of the three-way solenoid valve 5 to connect, so that the cutting fluid flows back into the lower chamber of the cutting fluid recovery tank 2 and re-enters the plate-fin heat exchanger 3 for cooling.

[0038] Additionally, it should be noted that after the device has been used for a period of time, when the filtration efficiency of the filter element 6 decreases, it can be directly replaced by removing the cover 21. When it is necessary to clean the inside of the cutting fluid recovery tank 2, the manual three-way valve 16 needs to be manually adjusted to connect the first and third ports of the manual three-way valve 16, so that the cleaning water from the cutting fluid recovery tank 2 can be discharged through the third port of the manual three-way valve 16.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
