The filter device is cleaned by the setting of the cleaning device, which reduces the number of manual disassembly of the filter device and the cleaning of the cleaning device, thereby improving work efficiency.

[0051] 2. The filter layer is driven to rotate by the driving group, so that the filter layer part at the outlet of the suction fan can be replaced with a clean part in time, and the filter layer can be disassembled and assembled during replacement without interfering with the polishing work.

[0052] 3. The drive group drives the protrusion to move the paddle plate, which drives the ring plate to move and separate the ring plate from the filter layer. When the part of the filter layer with metal dust enters the range of the ring plate, the metal dust on the filter layer will not be scraped off by the ring plate. The spring drives the ring plate to reset and close to the filter layer. When the filter layer is moved by the protrusion to drop powder, the metal dust can fall into the collection box in a relatively closed space, which effectively reduces the occurrence of metal dust flying when it falls from the filter layer.

[0076] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0077] Reference Figure 1-6The steel pipe surface polishing equipment includes: a cabinet 101, a sand grinder 102, a suction fan 103, a filter device 104, and a cleaning device 105; a drop port 101a is opened on the upper surface of the cabinet 101; the sand grinder 102 has a pair of suction fans 103 fixed on the cabinet 101 and located on both sides of the drop port 101a; the suction fan 103 is fixed in the cabinet 101, and the inlet of the suction fan 103 is connected with the drop port 101a, and a mesh plate is laid on the drop port 101a to sieve larger particles; the filter device 104 is arranged in the cabinet 101, and the outlet of the suction fan 103 faces the filter device 104 to filter the inhaled air and metal dust; the cleaning device 105 is arranged on the cabinet 101, and is used to clean the filter device 104.

[0078] When the steel pipe is surface polished, the suction fan 103 is started to suck in the metal powder and other impurities generated by the polishing, and then sprayed on the filter device 104 to separate the air from the powder impurities. The metal powder and other impurities on the filter device 104 are then cleaned by the cleaning device 105 to extend the service life of the filter device 104.

[0079] The filtering device 104 includes: a rotating rod 104a, a first winding layer 104b, a second winding layer 104c, a filtering layer 104d, and a driving group 104e; the rotating rods 104a have four, which are rotatably arranged at the four corners of the cabinet 101; the first winding layer 104b surrounds the four rotating rods 104a; the second winding layer 104c surrounds the four rotating rods 104a and is located below the first winding layer 104b; the filtering layer 104d surrounds the four rotating rods 104a, and its upper and lower ends are respectively connected to the first winding layer 104b and the second winding layer 104c; the driving group 104e is arranged on the cabinet 101, and is transmission-connected to one of the rotating rods 104a to drive the rotating rod 104a to rotate.

[0080] The rotating rod 104a is composed of a first cylinder 104f, a second cylinder 104g and a third cylinder 104h. The first cylinder 104f is rotatably arranged on the cabinet 101; the second cylinder 104g is integrally formed on the first cylinder 104f and is located at the upper end of the first cylinder 104f; the third cylinder 104h is integrally formed on the second cylinder 104g and is located at the upper end of the second cylinder 104g; the first cylinder 104f, the second cylinder 104g and the third cylinder 104h are coaxial; the circumferential surfaces of the first cylinder 104f and the third cylinder 104h are both provided with meshing grooves 104i; the first winding layer 104b and the second winding layer 104h are connected to each other. 04c has meshing teeth 104j on its inner wall; the meshing teeth 104j on the first winding layer 104b mesh with the meshing groove 104i on the third cylinder 104h; the meshing teeth 104j on the second winding layer 104c mesh with the meshing groove 104i on the first cylinder 104f; the diameter of the first cylinder 104f is the same as the diameter of the third cylinder 104h, and the diameter of the first cylinder 104f is larger than the diameter of the second cylinder 104g, forming a groove so that the inner wall of the filter layer 104d will not contact the second cylinder 104g, thereby preventing the second cylinder 104g from contacting the filter layer 104d and causing metal dust to fall directly.

[0081] The driving group 104e has two output ends, one of which is a gear 104k meshing with the meshing groove 104i of the first cylinder 104f, and the other output end is a rotating shaft 104l.

[0082] After long-term dust collection and filtration, a lot of metal dust and the like adhere to the filter layer 104d. At this time, the driving group 104e is started to drive the rotating rod 104a connected to the driving group 104e to rotate. The rotating rod 104a drives the filter layer 104d to rotate around the four rotating rods 104a, and the filter layer 104d at the air outlet is partially transferred to the position of the cleaning device 105 to clean the filter layer 104d.

[0083] The cleaning device 105 includes: a convex block 105a and a collecting group 105b; the convex block 105a is constructed in the shape of an elliptical plate and is fixed on the rotating shaft 104l. When the convex block 105a rotates, it collides with the filtering layer 104d; the collecting group 105b is arranged in the cabinet 101.

[0084] The collecting group 105b includes: a collecting box 105c, a ring plate 105d, a dial plate 105e, a guide rod 105f, and a spring 105g; the collecting box 105c is arranged on a side of the cabinet 101 close to the filter layer 104d, and the opening of the collecting box 105c faces the filter layer 104d; the ring plate 105d is horizontally slidably arranged on the collecting box 105c, and the ring plate 105d surrounds the opening of the collecting box 105c and is closely attached to the filter layer 104d; there is a slide groove 105d on the side wall of the collecting box 105c 05h, the dial plate 105e is slidably arranged in the slide groove 105h, and the dial plate 105e is fixedly connected to the ring plate 105d; the guide rod 105f is penetrated by the dial plate 105e, and the dial plate 105e is slidably connected to the guide rod 105f, and the guide rod 105f is placed horizontally; the spring 105g is sleeved on the guide rod 105f, and the two ends of the spring 105g are respectively abutted against the collection box 105c and the dial plate 105e, so as to push the dial plate 105e to slide toward the opening direction of the collection box 105c.

[0085] When the protrusion 105a rotates, it will hit the dial plate 105e, driving the dial plate 105e to move away from the opening of the collection box 105c, driving the ring plate 105d to separate from the filter layer 104d. When the protrusion 105a continues to rotate, the protrusion 105a is separated from the dial plate 105e, and the spring 105g drives the dial plate 105e and the ring plate 105d to reset, and the ring plate 105d is tightly attached to the filter layer 104d again. At this time, the gear 104k of the driving group 104e still drives the rotating rod 104a to rotate, driving the filter layer 104d to move.

[0086] The rotation ratio of the driving group 104e can be set to adjust the protrusion 105a to drive the ring plate 105d to move, so that when the ring plate 105d is separated from the filter layer 104d, the part of the filter layer 104d that was originally at the air outlet of the suction fan 103 on the filter layer 104d enters the ring plate 105d, and after the protrusion 105a rotates and hits the filter layer 104d, the filter layer 104d vibrates, and the metal dust on the filter layer 104d is shaken off into the collection box 105c. When the protrusion 105a continues to rotate, the protrusion 105a pushes the dial plate 105e and the ring plate 105d to move again, and the ring plate 105d is separated from the filter layer 104d, and the part of the filter layer 104d that was originally in the ring plate 105d is drawn out of the range of the ring plate 105d.

[0087] A turntable 106 is also fixed on the rotating shaft 104l, and the turntable 106 is located above the protrusion 105a. A pair of protrusions 107 are provided on the upper end surface of the turntable 106, and the pair of protrusions 107 are located on both sides of the turntable 106. The protrusions 107 are located on both sides of the long axis of the protrusion 105a; a push rod 108 is fixed on one side of the collection box 105c, and the lower end surface of the push rod 108 is hemispherical and abuts against the upper end surface of the turntable 106. When the turntable 106 rotates, the protrusion 107 will push up the push rod 108; a support plate 109 is fixed in the cabinet 101, and the collection box 105c is hinged to the support plate 109.

[0088] When the rotating shaft 104l rotates, it drives the turntable 106 to rotate, so that the protrusion 107 lifts the push rod 108. After the push rod 108 moves up, it drives the collecting box 105c to shake. After the shaking, the collecting box 105c shakes the dust on the inner wall of the collecting box 105c to the bottom of the collecting box 105c, which is convenient for collection and sorting, so as to avoid excessive metal dust adhering to the inner wall of the collecting box 105c and overflowing. At the same time, a magnet can be installed at the bottom of the collecting box 105c to adsorb the metal dust on the bottom of the collecting box 105c.

[0089] By arranging the protrusions 107 on both sides of the long axis of the protrusion 105a, when the protrusion 107 pushes up the push rod 108, the protrusion 105a drives the shift plate 105e to move so that the ring plate 105d is separated from the filter layer 104d, so that when the collection box 105c shakes, the ring plate 105d is separated from the filter layer 104d, thereby avoiding the problem of the ring plate 105d and the filter layer 104d being tightly attached to each other when the collection box 105c shakes, thereby protecting the filter layer 104d and extending the service life of the filter layer 104d.
