Description

Technical Field

[0001] This utility model belongs to the field of wire cutting technology, and in particular relates to an anti-clogging device for a filter system of wire cutting equipment. Background Technology

[0002] In the online cutting process, cutting fluid is indispensable for lubrication and flushing away metal chips. Existing machine tools use cutting fluid equipment that only purifies and filters the fluid, playing a role in flushing away chips and lubrication. Currently, multi-stage filters are used to filter out large particles in the cutting fluid. These large particles include residual metal chips from machining, as well as cotton threads and rubber residue from the operator's gloves. Over time, the screen of the first-stage filter is prone to clogging, requiring machine shutdown for cleaning, which affects production efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a wire cutting equipment filtration system anti-clogging device that can clean the surface of the primary filter element in a timely manner.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an anti-clogging device for a wire cutting equipment filtration system, comprising a filter housing, a base, support columns, a filter tube, a filter element, a rotating shaft, an impeller, cleaning blades, a permanent magnet, a touch switch, a corrugated telescopic tube, an upper connecting plate, a bushing, a lower connecting plate, a guide rod, a support sleeve, a spring, a limit ring, and an alarm device. The filter housing is fixedly mounted on the base by four support columns. The filter element and the filter tube are integrally formed. The filter element is configured as a frustum-shaped structure. The filter element has filter holes communicating with the filter tube. The filter tube is sealed and fixedly mounted at the bottom of the filter housing. The rotating shaft is rotatably and sealedly mounted inside the filter element. The impeller is placed inside the filter tube and fixedly sleeved on the rotating shaft. Two cleaning blades are fixedly mounted on the top of the rotating shaft. Furthermore, the cleaning paddle is attached to the outer surface of the filter element, and four guide rods are distributed in a rectangle with their upper and lower ends fixedly connected to the filter box and the base, respectively. The upper connecting plate and the lower connecting plate are respectively sealed and fixedly installed at the upper and lower ends of the corrugated telescopic tube. The lower connecting plate is slidably sleeved on the guide rod, and the upper connecting plate is sealed and fixedly installed at the bottom of the filter box. The support sleeve and the spring are both sleeved on the guide rod, and the upper and lower ends of the spring act on the lower connecting plate and the support sleeve, respectively. The lower end of the bushing is fixedly installed on the lower connecting plate, and the upper end of the bushing is slidably sealed and installed on the bottom plate of the filter box. The top of the bushing has a blind hole, and the bottom of the permanent magnet is provided with a connecting rod. The connecting rod is slidably inserted into the blind hole at the top of the bushing. The touch switch is fixedly installed on the base and is connected to the alarm device through a circuit.

[0005] Furthermore, a connecting flange is provided at the bottom of the filter tube.

[0006] Furthermore, a lifting ring is fixedly installed on the top of the permanent magnet.

[0007] Furthermore, the alarm device is configured as an audible and / or visual alarm device.

[0008] Compared with the prior art, the advantages of this utility model are:

[0009] When the pump draws cutting fluid for circulation and filtration, the impeller drives two cleaning blades to rotate continuously and promptly clean the outer surface of the filter element. This prevents large particles of debris from adhering to and accumulating on the outer surface of the filter element, causing blockage and extending the maintenance and cleaning cycle of the filter element. At the same time, the permanent magnet is used to adsorb iron filings in the cutting fluid, reducing the workload of the secondary filter and extending its service life. Attached Figure Description

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figure 1 and Figure 2The wire cutting equipment filter system anti-clogging device shown includes a filter housing 1, a base 2, support columns 3, a filter tube 4, a filter element 41, a rotating shaft 5, an impeller 51, cleaning blades 52, a permanent magnet 6, a touch switch 7, a corrugated telescopic tube 8, an upper connecting plate 80, a bushing 81, a lower connecting plate 82, a guide rod 9, a support sleeve 91, a spring 92, a limit ring 93, and an alarm device. The filter housing 1 is fixedly mounted on the base 2 by four support columns 3. The filter element 41 is integrally formed with the filter tube 4. The filter element 41 is configured as a frustum-shaped structure. The filter element 41 has filter holes that communicate with the filter tube 4. The filter tube 4 is sealed and fixedly mounted at the bottom of the filter housing 1. The rotating shaft 5 is rotatably and sealedly mounted inside the filter element 41. The impeller 51 is placed inside the filter tube 4 and is fixedly sleeved on the rotating shaft 5. Two cleaning blades 52 are fixedly mounted on the top of the rotating shaft 5. Four guide rods 9 are rectangularly distributed on the outer surface of the filter element 41, with their upper and lower ends fixedly connected to the filter housing 1 and the base 2, respectively. The upper connecting plate 80 and the lower connecting plate 82 are respectively sealed and fixedly installed at the upper and lower ends of the corrugated telescopic tube 8. The lower connecting plate 82 is slidably sleeved on the guide rods 9, and the upper connecting plate 80 is sealed and fixedly installed at the bottom of the filter housing 1. The support sleeve 91 and the spring 92 are both sleeved on the guide rods 9. The upper and lower ends of the spring 92 act on the lower connecting plate 82 and the support sleeve 91, respectively. The lower end of the bushing 81 is fixedly installed on the lower connecting plate 82, and the upper end of the bushing 81 is slidably and sealedly installed on the bottom plate of the filter housing 1. The top of the bushing 81 has a blind hole. The bottom of the permanent magnet 6 is provided with a connecting rod, which is slidably inserted into the blind hole at the top of the bushing 81. The touch switch 7 is fixedly installed on the base 2 and is connected to the alarm device through a circuit. The alarm device is set as a sound and / or light alarm device.

[0015] The filter tube 4 is provided with a connecting flange at the bottom, and the filter tube 4 is sealed and fixed to the pump hose.

[0016] The permanent magnet 6 is fixedly mounted on the top of a lifting ring 61, which is attached to the lifting ring 61 by a traction rope 61, so that the permanent magnet 6 can be pulled upward and taken out.

[0017] The cutting fluid in the filter housing 1 is drawn and circulated by a pump for filtration. The filter element 41 acts as a primary filter to filter large particles in the cutting fluid of the wire cutting equipment. The large particles are adsorbed onto the filter element 41 under the action of liquid flow. The flowing cutting fluid drives the filter element 41, the rotating shaft 5 and the cleaning blades 52 to rotate synchronously. The cleaning blades 52 easily move the large particles adsorbed on the surface of the filter element 41, avoiding excessive adhesion of large particles on the surface of the filter element 41 and causing blockage. The permanent magnet 6 can adsorb iron filings in the cutting fluid. When the permanent magnet 6 adsorbs iron filings, its weight increases continuously. It overcomes the elastic force of the spring 92 and moves downward to contact the touch switch 7, which generates an electrical signal and sends it to the alarm device. The operator can then clean and replace the permanent magnet 6. The two cleaning blades 52 only block 1 / 20 of the outer surface of the filter element 41 and do not affect the flow rate of the cutting fluid through the filter element 41.
