Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting fluid processing technology, and in particular to a circulating replenishment device for automatically adjusting the concentration of cutting fluid. Background Technology
[0002] In metal cutting processes, cutting fluid plays a crucial role in cooling, lubrication, cleaning, and rust prevention. The concentration of the cutting fluid directly affects its performance. Too low a concentration leads to reduced lubrication and rust prevention, increased tool wear, and compromised workpiece quality; too high a concentration results in foaming and residue, causing waste and potentially triggering skin allergies in operators and environmental problems.
[0003] During the recycling process, the concentration of cutting fluid will decrease due to oil-water separation, fine filtration, and sterilization. Cutting fluid at this concentration is generally not usable directly and needs to be manually added and metered to adjust the concentration. This method is labor-intensive and inefficient. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the processed cutting fluid cannot be used directly and requires manual addition and metering to adjust the concentration in the existing technology. This method is labor-intensive and inefficient. Therefore, this invention proposes a circulating replenishment device for automatically adjusting the concentration of cutting fluid.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A circulating supply device for automatically adjusting the concentration of cutting fluid, comprising: The housing contains a second metering pump, and the outlet of the second metering pump is connected to an outlet pipe that extends to the outside of the housing. The liquid storage tank and the raw material tank are located on one side of the box, and both are connected to the inside of the box. The chamber also contains a testing box, a static mixer fixed by a support frame, and two first metering pumps.
[0006] In one possible design, the static mixer consists of an outer tube, a baffle, and two fixed connection heads. The baffle is fixed inside the outer tube, and one end of the outer tube is fixedly connected to the test box through a connection head. The two cutting fluids are accelerated to mix by the baffle inside the static mixer and then flow into the test box.
[0007] In one possible design, the outlet ends of the two first metering pumps are each connected to a first connecting pipe. A tee pipe is provided between the two first connecting pipes and another connector of the static mixer. The inlet end of the tee pipe is fixedly connected to the outlet ends of the two first connecting pipes, and the outlet end is fixedly connected to the inlet end of the other connector, so that the two cutting fluids enter the static mixer through the tee pipe.
[0008] In one possible design, each of the two first metering pumps is equipped with a second connecting pipe between itself and the storage tank and the raw material tank, respectively. The inlet end of each of the two second connecting pipes is connected to the storage tank and the raw material tank, respectively, and each of the two second connecting pipes is equipped with a solenoid valve. The outlet end of each of the two second connecting pipes is connected to the inlet end of the two first metering pumps. The flow of cutting fluid is controlled by the solenoid valves to achieve precise quantitative extraction.
[0009] In one possible design, liquid concentration sensors are installed on the outer walls of both the detection tank and the storage tank, with their probes extending into the storage tank and the detection tank, respectively. The liquid concentration sensor on one side of the detection tank further detects the new concentration of cutting fluid to determine whether it meets the required concentration.
[0010] In one possible design, a control platform is installed on the outer wall of the housing. The control platform is electrically connected to two liquid concentration sensors, two first metering pumps, two solenoid valves, and a second metering pump. Based on the detection data of the liquid concentration sensors, the control platform controls the operation of the first metering pumps, solenoid valves, and the second metering pump to ensure the timeliness and quality stability of the cutting fluid.
[0011] In this application, the storage tank is used to store the treated cutting fluid, and the raw material tank contains the raw cutting fluid. During use, the required cutting fluid concentration is set via a control platform, and the concentration of the treated cutting fluid inside the storage tank is detected by a liquid concentration sensor. The control platform then opens two corresponding metering pumps and solenoid valves connected in series. One set of metering pumps and solenoid valves quantitatively extracts the treated cutting fluid from the storage tank according to the required cutting fluid concentration. The other set of metering pumps and solenoid valves quantitatively extracts the raw cutting fluid from the raw material tank according to the required cutting fluid concentration. The two cutting fluids are connected via a three-way valve. The tube enters the static mixer, where the baffles inside guide the flow, accelerating the mixing of the two cutting fluids. The mixture then flows into the detection tank, where a liquid concentration sensor on one side further detects the new cutting fluid concentration and transmits the data to the control platform. The control platform processes the data to determine if the required cutting fluid concentration is met. If the concentration is not met, the control platform automatically adjusts the flow rate of the two first metering pumps. When the required cutting fluid concentration is met, the second metering pump is activated, delivering the cutting fluid of the required concentration to the machine tool through the outlet pipe.
[0012] Beneficial effects: In this utility model, the automatic adjustment and circulation replenishment device for cutting fluid concentration, through the cooperation of two sets of first metering pumps and solenoid valves, can accurately and quantitatively extract the processed cutting fluid and the original cutting fluid according to the set requirements, ensuring accurate mixing ratio and effectively meeting the diverse requirements for cutting fluid concentration under different working conditions. In this utility model, the automatic adjustment and circulation replenishment device for cutting fluid concentration has a special structure of static mixer that can accelerate the mixing of two cutting fluids, and the liquid concentration sensor on one side of the detection box can further detect the new concentration of cutting fluid. The second metering pump can deliver cutting fluid to the machine tool in a timely manner when the concentration reaches the standard, ensuring the timeliness and quality stability of cutting fluid use. This invention can accurately adjust the concentration of cutting fluid, ensure mixing efficiency and quality testing, and deliver qualified cutting fluid in a timely manner, effectively improving the efficiency of cutting fluid use and processing quality.

[0017] Reference Figures 1 to 2The storage tank 4 and the raw material tank 5 are connected to the interior of the box body 1 through pipes. The detection box 7 is fixedly installed inside the box body 1 with bolts. The detection box 7 is used to detect the concentration of the prepared cutting fluid. The static mixer 9 consists of an outer tube 16, a baffle 17 and two connectors 8. The baffle 17 is fixedly installed inside the outer tube 16 by welding. The two ends of the outer tube 16 are welded to the two connectors 8 respectively. The static mixer 9 is welded and fixed to the detection box 7 through one of the connectors 8 to ensure that the mixed cutting fluid can flow smoothly into the detection box 7.
[0018] Reference Figure 1 and Figure 2 Two first metering pumps 11 are fixedly installed inside the housing 1 by bolts. The outlet ends of the two first metering pumps 11 are welded and fixed with first connecting pipes 12. A three-way pipe 10 is installed between the two first connecting pipes 12 and another connector 8 of the static mixer 9. The inlet end of the three-way pipe 10 is welded and fixedly connected to the outlet end of the two first connecting pipes 12, and the outlet end of the three-way pipe 10 is welded and fixedly connected to the inlet end of the other connector 8, so that the cutting fluid drawn from the two first metering pumps 11 can enter the static mixer 9 through the three-way pipe 10.
[0019] Reference Figure 1 and Figure 2 Each of the two first metering pumps 11 is connected to the liquid storage tank 4 and the raw material tank 5 by a second connecting pipe 13. The inlet end of each of the two second connecting pipes 13 is welded and fixedly connected to the liquid storage tank 4 and the raw material tank 5, respectively. Solenoid valves 14 are fixedly installed on each of the two second connecting pipes 13. The outlet end of each of the two second connecting pipes 13 is welded and fixedly connected to the inlet end of each of the two first metering pumps 11, and the flow of cutting fluid is controlled by the solenoid valves 14.
[0020] Reference Figure 1 and Figure 2 Liquid concentration sensors 6 are fixedly installed on the outer walls of both the detection tank 7 and the storage tank 4 by bolts, and the detection ends of the two liquid concentration sensors 6 extend into the storage tank 4 and the detection tank 7 respectively, for detecting the concentration of cutting fluid.
[0021] Reference Figure 1 and Figure 2 The control platform 2 is bolted to the outer wall of the housing 1. The control platform 2 is electrically connected to two liquid concentration sensors 6, two first metering pumps 11, two solenoid valves 14, and a second metering pump 15 to realize data transmission and control command sending. This application can be used in the field of cutting fluid processing, or in other fields applicable to this application.
[0022] In another embodiment: Reference Figures 1 to 3A circulating replenishment device for automatically adjusting the concentration of cutting fluid is disclosed, which is applied in the field of cutting fluid processing. A storage tank 4 stores the treated cutting fluid, and a raw material tank 5 contains the raw cutting fluid. Before using the device, the required cutting fluid concentration is set via a control platform 2. After the device is started, two liquid concentration sensors 6 begin operation. One of the liquid concentration sensors 6 detects the concentration of the treated cutting fluid inside the storage tank 4 and transmits the data to the control platform 2. Based on the set cutting fluid concentration and the detected concentration in the storage tank 4, the control platform 2 calculates the amount of cutting fluid to be extracted from the storage tank 4 and the raw material tank 5 using an internally preset program. Then, it opens two corresponding metering pumps 11 and solenoid valves 14 connected in series. One set of metering pumps 11 and solenoid valves 14 quantitatively extracts the treated cutting fluid from the storage tank 4 according to the required cutting fluid concentration, while the other set of metering pumps 11 and solenoid valves 14 quantitatively extracts the raw cutting fluid from the raw material tank 5 according to the required cutting fluid concentration. Two cutting fluids enter the static mixer 9 via corresponding second connecting pipes 13, first metering pumps 11, and first connecting pipes 12, respectively, and then via a three-way pipe 10. Inside the static mixer 9, baffles 17 guide the flow of the cutting fluids, accelerating their mixing. The mixed cutting fluid then flows into the detection tank 7. A liquid concentration sensor 6 on one side of the detection tank 7 further detects the new concentration of cutting fluid and transmits the data to the control platform 2. The control platform 2 processes the received data to determine if it meets the required cutting fluid concentration. If the concentration is insufficient, the control platform 2 automatically adjusts the flow rate of the two first metering pumps 11, readjusting the amount of cutting fluid drawn from the storage tank 4 and the raw material tank 5, and repeats the mixing and detection until the required cutting fluid concentration is met. When the required cutting fluid concentration is met, the control platform 2 activates the second metering pump 15, which delivers the cutting fluid of the required concentration to the machine tool via the outlet pipe 3 for use.
