Description

Technical Field

[0001] This utility model belongs to the field of supply device technology, specifically relating to a centralized proportioning and supply device for grinding fluid. Background Technology

[0002] Currently, various types of grinding fluids are frequently required during the machining and grinding process. Cutting fluid is usually an indispensable production factor in most machining processes, enabling better machining and grinding effects. The supply of general machining and grinding fluids cannot meet the needs, and appropriate methods need to be adopted to improve the supply effect.

[0003] Chinese Patent Application No. 2015210600007 discloses a machine tool grinding fluid supply system, including a feeding tank, a distributing tank, a collecting tank, a first grinding fluid filter, and a second grinding fluid filter. One end of the distributing tank is connected to the outlet of the feeding tank, and the other end of the distributing tank is closed. The distributing tank has multiple outlets for connecting to the grinding fluid inlets of each machine tool. Both ends of the collecting tank are closed, and the collecting tank has multiple inlets for connecting to the grinding fluid outlets of each machine tool. One outlet is located at the bottom of one end of the collecting tank. The inlet of the first grinding fluid filter is connected to the outlet of the collecting tank. The inlet of the second grinding fluid filter is connected to the outlet of the first grinding fluid filter, and the outlet of the second grinding fluid filter is connected to the inlet of the feeding tank.

[0004] The above solution enables a unified supply of grinding fluid to all machine tools, ensuring a consistent concentration of grinding fluid on each machine. However, if a different concentration needs to be changed, diluent must be added manually. The drawbacks of this method are its slow processing speed and the ease with which errors can occur in the mixing ratio. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a centralized grinding fluid mixing and supply device, comprising a storage tank, a stirring vessel, and a supply pipe mechanism. The storage tank has a grinding fluid supply chamber and a diluent supply chamber above it, and a drive chamber below it. The drive chamber is equipped with a first pump and a second pump. The first pump is connected to a first suction pipe and a first discharge pipe, the first suction pipe communicating with the grinding fluid supply chamber and the first discharge pipe communicating with the stirring vessel. The second pump is connected to a second suction pipe and a second discharge pipe, the second suction pipe communicating with the diluent supply chamber and the second discharge pipe communicating with the stirring vessel. The stirring vessel contains a stirring assembly, and a connecting pipe is connected to the bottom of the stirring vessel, the connecting pipe being connected to the supply pipe mechanism.

[0006] Preferably, the stirring mechanism includes a support frame that extends directly above the mixing vessel and is connected to a stirring motor. Below the stirring motor is a stirring rod that extends into the mixing vessel and is connected to stirring blades.

[0007] Preferably, the supply pipe mechanism includes a main supply pipe and several tee pipes connected to the main supply pipe. The tee pipes are connected to a first liquid outlet port and a second liquid outlet port. The first liquid outlet port is detachably connected to a first supply pipe, and the second liquid outlet port is detachably connected to a second supply pipe. Both the first liquid outlet port and the second liquid outlet port are provided with control valves.

[0008] Preferably, both the first and second liquid outlet ports are provided with external threads, and both the first and second supply pipes are provided with connecting parts, the inner side of which is provided with internal threads.

[0009] Preferably, both the first supply pipe and the second supply pipe are provided with a filter screen at their bottom.

[0010] The advantages of this utility model are:

[0011] 1. This solution automatically extracts and mixes the grinding fluid and diluent using a first and a second pump, respectively, achieving automated mixing of the grinding fluid concentration. This significantly improves work efficiency, reduces the need for manual operation, and minimizes mixing errors caused by human factors, thus ensuring consistent and accurate grinding fluid concentration on each machine tool.

[0012] 2. This solution significantly reduces the mixing time through its stirring mechanism. This improves production efficiency, reduces waiting time, and allows the grinding fluid to reach the required concentration and be supplied to the machine tool more quickly.

[0013] 3. In this solution, if the first supply pipe becomes blocked, the control valve on the second outlet port can be opened to allow the second supply pipe to continue supplying liquid, thus ensuring continuous liquid supply. Attached Figure Description

[0023] Example 1, such as Figure 1-2As shown, a centralized grinding fluid mixing and supply device includes a storage tank 1, a stirring vessel 2, and a supply pipe mechanism. A grinding fluid supply chamber 3 and a diluent supply chamber 4 are located above the storage tank 1, and a drive chamber 5 is located below the storage tank 1. The drive chamber 5 is equipped with a first pump 6 and a second pump 7. The first pump 6 is connected to a first suction pipe 8 and a first discharge pipe 9. The first suction pipe 8 communicates with the grinding fluid supply chamber 3, and the first discharge pipe 9 passes through the grinding fluid supply chamber 3 and communicates with the stirring vessel 2. The first pump 6 quantitatively pumps the grinding fluid from the grinding fluid supply chamber 3 into the stirring vessel 2. The second pump 7 is connected to a second suction pipe 10 and a second discharge pipe 11. The second suction pipe 10 communicates with the diluent supply chamber 4, and the second discharge pipe 11 communicates with the stirring vessel 2. The second pump 7 quantitatively pumps the diluent from the diluent supply chamber 4 into the stirring vessel 2. The diluent can be any commercially available one. In this embodiment, water is used as the diluent, which can reduce the corresponding cost. The stirring vessel 2 is equipped with a stirring component to stir the mixed liquid. The bottom of the stirring vessel 2 is connected to a connecting pipe 12, which is connected to the supply pipe mechanism.

[0024] By automatically controlling the extraction and mixing of grinding fluid and diluent using the first pump 6 and the second pump 7 respectively, the grinding fluid concentration is automatically proportioned. This significantly improves work efficiency, reduces the need for manual operation, and minimizes proportioning errors caused by human factors, thus ensuring consistent and accurate grinding fluid concentration on each machine tool. Furthermore, this solution allows for easy adjustment of the operating parameters of the first pump 6 and the second pump 7 to change the mixing ratio of grinding fluid and diluent, achieving the supply of grinding fluid of different concentrations according to different processing requirements. This flexibility improves production adaptability and efficiency.

[0025] Combination Figure 2 The stirring mechanism includes a support frame 13 extending directly above the mixing vessel 2 and connected to a stirring motor 14. Below the stirring motor 14 is a stirring rod 15 extending into the mixing vessel 2 and connected to stirring blades 16-1. The stirring motor 14 drives the stirring rod 15 and stirring blades 16-1 to rotate within the mixing vessel 2, achieving thorough mixing of the grinding fluid and diluent. The stirring blades 16-1 are designed to generate strong convection and shear forces, promoting mixing and homogenization of the liquids, thus ensuring accurate and consistent grinding fluid concentration. The operation of the stirring mechanism ensures uniform mixing of the grinding fluid in all directions within the mixing vessel 2. This avoids localized over- or under-concentration, improving the overall effectiveness of the grinding fluid. The stirring mechanism significantly reduces the mixing time, improving production efficiency, reducing waiting time, and allowing the grinding fluid to reach the required concentration and be supplied to the machine tool more quickly.

[0026] Combination Figure 3-5The supply pipe mechanism includes a main supply pipe 16 and several tee pipes 17 connected to the main supply pipe. A first outlet port 18 and a second outlet port 19 are connected to the tee pipes 17. A first supply pipe 20 is detachably connected to the first outlet port 18, and a second supply pipe 21 is detachably connected to the second outlet port 19. Both the first and second outlet ports 18 and 19 are equipped with control valves 22. When the first supply pipe 20 becomes blocked, the control valve 22 on the second outlet port 19 can be opened to allow the second supply pipe 21 to continue supplying liquid, ensuring continuous liquid supply. The control valve 22 can be any structure such as a butterfly valve, ball valve, gate valve, or stop valve. The control valve 22 is a known technology in the art, and its specific structure will not be described in detail in this embodiment. Both the first outlet port 18 and the second outlet port 19 are provided with external threads 23. Both the first supply pipe 20 and the second supply pipe 21 are provided with connecting parts 24, the inner side of which is provided with internal threads. The threaded connection allows for quick disassembly of the supply pipes, facilitating the clearing of blocked pipes. Both the first supply pipe 20 and the second supply pipe 21 are provided with filter screens 25 at their bottoms. The filter screens 25 effectively block and remove solid impurities and particulate matter from the grinding fluid.
