Description

Technical Field

[0001] The utility model relates to the field of liquid supply and return of machine tools, specifically to the field of self-cleaning machine tool water tanks. Background Technique

[0002] Whether it is a lathe or a grinding machine, cutting fluid is used when processing parts. Because in addition to large chips that can be discharged by a chip conveyor in the cutting fluid, there are many small particles that will enter the machine tool water tank through the machine tool chip removal filter screen. After a long time, a layer of sludge will accumulate at the bottom of the machine tool water tank. Generally, after the machine tool has worked for a period of time, the machine tool operator will drain the cutting fluid in the water tank and open the tank cover to use tools such as a scraping shovel for cleaning. Cleaning the water tank requires the machine tool to stop, which will affect the production efficiency of the workshop. And the liquid used in machine tools is generally oily wastewater, which will breed bacteria over time and produce a liquid with an odor, which is also harmful to the human body.

[0003] At present, the machine tool water tank is provided by the machine tool equipment manufacturer and is matched with the machine tool equipment. The existing machine tool water tank does not consider the problems of particulate matter and waste liquid and miscellaneous oil treatment. Many machining workshops prefer centralized liquid supply, which automatically processes, proportions, and supplies liquid to the machine tool water tank without manual participation. The machine tool water tank is located at the machine tool end and is an important link in centralized liquid supply. How to remove particulate matter in the cutting fluid waste liquid in the water tank and treat miscellaneous oil at the machine tool end, and ensure that the cutting fluid supplied to the machine tool tool is clean liquid is an urgent problem to be solved in the centralized liquid supply project.

[0004] At present, in some centralized liquid supply projects, the particulate matter in the liquid of the machine tool water tank is precipitated and stratified, and the upper layer of liquid is pumped to the treatment equipment for oil removal. After the purified liquid is pumped into the machine tool water tank, the particulate matter precipitated at the bottom will be washed up again, resulting in the cutting fluid supplied to the tool still containing particulate matter, and the problem of particulate matter in the liquid used in the machine tool cannot be solved.

Detailed implementation mode

[0039] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation mode.

[0040] Embodiment 1:

[0041] As Figure 1 and Figure 2 shown, a machine tool water tank circulating cleaning device includes a machine tool water tank 1, and the machine tool water tank 1 includes a first chamber 10 and a second chamber 11; a baffle 12 is arranged between the first chamber 10 and the second chamber 11. The first chamber 10 is connected to a self-cleaning circulation loop, and the self-cleaning circulation loop includes: a suction mechanism 2, a precision filter 3, and a liquid spraying pipe 5 that are connected in sequence. The precision filter 3 is located outside the machine tool water tank 1. The liquid inlet end of the precision filter 3 is connected to the suction mechanism 2, and the liquid outlet end of the precision filter 3 is connected to the liquid spraying pipe 5.

[0042] The precision filter 3 can be a filter bag with an internal filter cloth or a bag filter. If it is an upper-filter type precision filter, the liquid enters the filter bag, and the powdery filter residue is intercepted inside the filter bag, and the clear liquid is discharged from below the filter tank. The lower part of the filter tank is connected to the liquid spraying pipe 5 through a pipeline. If it is a lower-filter type filter, the liquid enters from the outside of the filter bag, the filter residue is intercepted outside the filter bag, and the clear liquid comes out from inside the filter bag. In this embodiment, an upper-filter type filter is adopted. The precision filter 3 can also be a filter element filter.

[0043] As Figures 2 - 4 , the machine tool water tank 1 includes surrounding plates 15 and a bottom plate 16 around it. The bottom plate 16 is inclined towards the second chamber 11. A baffle 12 is arranged on the lower side of the inclined section. The baffle 12 is provided with a bent edge 120 above it. A filter screen plate 13 is arranged above the baffle 12, and the filter screen plate 13 enables the first chamber 10 and the second chamber 11 to communicate above the baffle 12; flow guiding members 14 are arranged on the front and back sides of the baffle 12. The area between the two flow guiding members 14 to the baffle 12 gradually decreases from large to small first and then is the same as the size of the baffle 12. The two flow guiding members 14, the bottom plate 16, the baffle 12 and the bent edge 120 enclose a collection area. The liquid suction port 20 of the suction mechanism 2 is located in the collection area. In this embodiment, the suction mechanism is a particle pump, a submersible pump or a submersible stirring pump.

[0044] As Figure 2, above the first chamber 10, there is a magnetic filter 4. The magnetic filter 4 is provided with a waste liquid inlet 40 used by the machine tool. After the waste liquid is filtered by the magnetic filter 4, it is discharged into the first chamber 10.

[0045] As Figure 3 , Figure 4 , in the second chamber 11, there are also a treatment liquid inlet 111 and an oil liquid outlet 1101. The oil liquid outlet 1101 is located on the downstream side. The oil liquid outlet 1101 is connected to an overflow tank 110. The overflow tank 110 is arranged parallel to the short side of the machine tool water tank 1. One end of the overflow tank 110 is provided with the oil liquid outlet 1101, and the other end is provided with an adjusting mechanism 1102. The adjusting mechanism 1102 adjusts the relative height between the overflow tank 110 and the machine tool water tank 1. The adjusting mechanism 1102 includes a seat plate, and a screw rod is provided on the seat plate. The screw rod passes through the oil overflow tank 110, and adjusting nuts are provided above and below the overflow tank 110. The height of the notch of the overflow tank 110 is slightly lower than the liquid level height. The overflow tank 110 is provided with a serrated notch, which can break the oil film, so that all the floating oil on the surface of the oil tank enters the overflow tank 110 and is then discharged through the oil liquid outlet 1101.

[0046] As Figure 3 , the treatment liquid inlet 111 extends from the bottom of the second chamber 11 and is located at the bottom of the second chamber. The treatment liquid inlet 111 includes a horizontal pipe 1110 and a vertical pipe 1112. A number of spray holes are provided on the horizontal pipe 1110. The liquid is fed into the second chamber 11 in multiple spray hole modes, which can agitate the original liquid in the machine tool water tank by the treatment liquid, mix the treatment liquid with the original liquid, and ensure the uniform concentration of the liquid supplied to the machine tool cutter.

[0047] As Figure 3 , the oil liquid outlet 1101 introduces the oil-containing waste liquid into the subsequent external oil removal treatment equipment. After the oil removal treatment, the clean liquid is then introduced into the second chamber 11 through the treatment liquid inlet 111. Above the second chamber 11, there is a liquid supply pump 7. The liquid suction port of the liquid supply pump 7 is located below the liquid level of the second chamber 11 and is used to supply the filtered and purified liquid to the nozzles above the cutter and workpiece on the machine tool.

[0048] As Figure 5 , the pipeline led out from the liquid outlet end of the precision filter 3 is provided with a main spray pipe around the machine tool water tank. As Figure 4, a liquid spraying main pipe is provided with liquid spraying branch pipes 51. The liquid spraying branch pipes 51 pass through the enclosure plate 15 of the machine tool water tank. Inside the enclosure plate 15, the liquid spraying branch pipes 51 are connected to each nozzle pipe 501. The liquid spraying pipes 5 are installed close to the bottom plate 16 of the machine tool water tank. The liquid spraying main pipe is connected to the liquid spraying branch pipes 51 through a tee. The liquid spraying branch pipes 51 are connected to nozzles 50 with different installation angles. The nozzles 50 are flat-shaped, which can increase the liquid outflow speed of water. The nozzles 50 are arranged on the nozzle pipes 501. The nozzle pipes are connected to each other through quick-connection devices. The quick-connection devices are quick connectors 52, such as hose clamps, etc. During installation, the installation angles of the nozzles can be adjusted according to different liquid spraying angles. A row of nozzle pipes 501 is provided on the upstream side of the water flow. Two groups of nozzles in the same direction as the water flow direction and two groups of nozzles in the opposite direction to the water flow direction are provided. One to two rows of liquid spraying pipes are respectively provided on both sides of the water flow direction, and the nozzle directions are the same as the water flow direction.

[0049] such as Figure 1 , several divided cover plates 17 are provided above the machine tool water tank 1. Outside the cover plates 17, the power part 21 of the suction mechanism is provided. The power part of the liquid supply pump 7 is also located on the cover plate 17. The suction mechanism can be a submersible mixing pump. The submersible mixing pump has a built-in mixing part at the liquid suction port, which can play a dual role of mixing and suction.

[0050] The machine tool water tank can be externally placed on the machine tool, that is, not under the machine tool. To meet the need for centralized liquid supply, a machine tool water tank externally placed outside the machine tool is configured, such as Figure 2 , four casters 8 are provided at the bottom of the machine tool water tank, which can be used for movement. The movable machine tool water tank can replace the original machine tool water tank fixed at the bottom of the machine tool. Tightening bolts are also provided outside the four casters. Move this machine tool water tank to the side of the machine tool, fix it to the workshop floor using the tightening bolts, and then connect the pipes to the machine tool. The movable machine tool water tank can replace the original machine tool water tank, and is convenient for the disassembly, repair and replacement of the machine tool water tank.

[0051] The working principle of the self-cleaning machine tool water tank of the present utility model:

[0052] The machine tool water tank 1 includes a self-cleaning circulation loop and an external circulation loop. For the external circulation loop: The liquid supply pump 7 on the second chamber pumps the liquid above the machine tool for tool use. The used waste liquid is filtered by the magnetic filter 4, and the waste liquid carrying some particulate matter enters the first chamber 10. The first chamber 10 is connected to the self-cleaning circulation loop. For the self-cleaning circulation loop: The suction mechanism 2 pumps the dirty liquid with particulate matter to the precision filter 3. The purified liquid after being filtered by the filter is sprayed out through the spray pipe 5 by the nozzle 50, and the nozzles face different directions to spray and wash the particulate matter at the bottom of the water tank. The waste liquid containing particulate matter flows along the inclined bottom plate 16 and is guided by the guide member 14 into the collection area, and is sucked away again through the liquid suction port 20 of the suction mechanism 2 for filtration. The nozzles spray and wash the bottom from different angles to remove particulate matter in all directions without dead angles. Since the liquid suction port 20 is located within the baffle 12 and the bent edge 120, the particulate matter is basically retained in the collection area and will not escape to the second chamber 11 through the filter mesh plate.

[0053] The liquid filtered from particulate matter enters the second chamber 11 through the filter mesh plate 13. There is still floating oil in the waste liquid. The floating oil moves towards the overflow tank 110 under the push of the water flow. After the floating oil passes through the serrated notch of the overflow tank and the oil film is broken, all the oil liquid enters the overflow tank 110 and is discharged through the oil liquid outlet 1101. The oil liquid discharged through the oil liquid outlet 1101 is introduced into the oil removal treatment equipment, and the treated clean liquid is introduced into the second chamber 11 through the treated liquid inlet 111. The liquid in the second chamber is pumped out by the liquid supply pump 7 for use on the machine tool.

[0054] Embodiment 2

[0055] As Figure 6 , the difference from Embodiment 1 is that the width of the second chamber 11 of the machine tool water tank is greater than that of the first chamber 10. The machine tool water tank is arranged in an L-shaped structure, and the treated liquid inlet 111 is located at the position where the second chamber 11 extends beyond the first chamber 10. The treated liquid inlet 111 is offset from the filter mesh plate 13 to minimize the pollution of the treated liquid by particulate matter.

[0056] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
