Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and more specifically relates to a cutting fluid filtering device. Background Art

[0002] When cutting metal workpieces, cutting fluid needs to be sprayed on the workpiece. These cutting fluids are mixed with the metal cutting chips generated during the cutting process. However, this cutting fluid containing cutting chips cannot be sprayed directly on the workpiece for use. A filtering device is needed to remove the cutting chips before it can be used normally.

[0003] Current filtration devices usually use single-stage or multi-stage filters for filtration, and these filters usually use positive pressure. When the filter is blocked, it is easy to cause the filter or pipeline to burst. After the filter is depressurized, the pressure of the filtered cutting fluid is low and cannot quickly remove the heat from the cutting area. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a method in which the power structure is placed after the filter, and the cutting fluid is filtered through the primary filter and the secondary filter in sequence by suction, and an overflow valve is provided on the outlet pipe to prevent the damage of the tool caused by excessive pressure of the filtered cutting fluid.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a cutting fluid filtering device, comprising a frame, on which a primary filter, a secondary filter and a high-pressure water pump connected in sequence are arranged, the high-pressure water pump is connected to a motor, the primary filter is connected to a water inlet pipe, the outlet of the high-pressure water pump is connected to a water outlet pipe, the water outlet pipe is connected to an overflow valve, the overflow valve is connected to a return pipe, and the return pipe is connected to the inlet of the primary filter.

[0006] Furthermore, the outlet of the first-level filter is connected to a sewage pipe, and a stop valve is provided on the sewage pipe.

[0007] Furthermore, a passing block is provided on the frame, and the water inlet pipe, the water outlet pipe, the return pipe and the sewage pipe are all provided on the passing block.

[0008] Furthermore, pressure gauges are provided on the crossing block at locations corresponding to the water outlet pipe, the water return pipe and the sewage pipe.

[0009] Furthermore, a universal roller is provided at the bottom of the frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the high-pressure water pump is driven by a motor, and the used cutting fluid is filtered in turn through the primary filter and the secondary filter, and then flows back to the cutting area through the outlet pipe in a high-pressure state. At this time, the cutting fluid can be sprayed directly in front of the blade accurately and in sufficient quantities to quickly take away the heat from the cutting area. At the same time, this high-pressure cooling method increases the brittleness of the chips, making it easy to cut them, thereby obtaining short chips, so that the chips no longer entangle around the workpiece, and the processing process no longer requires frequent shutdowns due to manual removal of long entangled chips. At the same time, the overflow valve and the return pipe can prevent the pressure in the outlet pipe from being too high, causing damage to the pipeline or tool. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms "first" and "second" may explicitly or implicitly refer to one or more of these features. In the description of this utility model, "several" and "a number" mean two or more, unless otherwise specifically defined.

[0019] A cutting fluid filtering device includes a frame 4, on which a primary filter 1, a secondary filter 2 and a high-pressure water pump 3 connected in sequence are provided. The high-pressure water pump 3 is connected to a motor 31. The primary filter 1 is connected to a water inlet pipe 51, and the outlet of the high-pressure water pump 3 is connected to a water outlet pipe 53. The water outlet pipe 53 is connected to an overflow valve 56, and the overflow valve 56 is connected to a return pipe 54. The return pipe 54 is connected to the inlet of the primary filter 1.

[0020] The water inlet pipe 51 is connected to the inlet of the primary filter 1 . A transition pipe 52 is provided between the outlet of the primary filter 1 and the inlet of the secondary filter 2 . The outlet of the secondary filter 2 is connected to the inlet of the high-pressure water pump 3 .

[0021] Preferably, a low-pressure lift pump 8 is provided before the water inlet pipe 51 to make it easier for the cutting fluid to enter the primary filter 1 .

[0022] In this embodiment, the first-stage filter 1 is a pre-filter, and the second-stage filter 2 is a high-pressure filter.

[0023] During operation, the cutting fluid is pumped into the pre-filter through the lifting pump for filtration. The filtered cutting fluid flows into the high-pressure filter, and then is pressurized by the high-pressure water pump 3 and sent to the required tool water outlet through the outlet pipe 53, forming high-pressure water outlet. This high-pressure water outlet can accurately reach the cutting area between the blade surface and the chips, effectively reducing the cutting heat in the cutting area.

[0024] Usually there is a pressure control valve body in front of the water outlet of the tool. When the cutting fluid pressure in the outlet pipe 53 is too high, it can flow back to the pre-filter through the overflow valve 56 and the return pipe 54. Of course, the overflow valve 56 can also directly flow the high-pressure cutting fluid to the outside for pressure relief to achieve the purpose of explosion prevention.

[0025] In this embodiment, the outlet of the primary filter 1 is preferably connected to a sewage pipe 55 , and a stop valve 551 is provided on the sewage pipe 55 .

[0026] By opening the stop valve 551, the cutting fluid in the primary filter 1 can be discharged. In this embodiment, the outlet of the primary filter 1 is at its bottom. When the stop valve 551 is opened, the cutting fluid can automatically flow out by gravity.

[0027] In this embodiment, the frame 4 is preferably provided with a passage block 6 , and the water inlet pipe 51 , the water outlet pipe 53 , the return pipe 54 , and the sewage pipe 55 are all provided on the passage block 6 .

[0028] The crossing block 6 is provided with holes for conveniently connecting the water pipes.

[0029] In this embodiment, the crossing block 6 is preferably provided with pressure gauges 7 at locations corresponding to the water outlet pipe 53 , the water return pipe 54 and the sewage pipe 55 .

[0030] The pressure state of each cutting fluid position can be monitored in real time by the pressure gauge 7.

[0031] In this embodiment, a universal roller 41 is preferably provided at the bottom of the frame 4 .

[0032] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
