Utility model content
Technical problem to be solved in the utility model is to provide in a kind of oil pipe pipe and cleans cutter, has solved in the past cleaning oil pipe trouble, cost high and clean halfway problem.
The technical scheme in the invention for solving the above technical problem is: in oil pipe pipe, clean cutter, this cleaning cutter comprises cutter hub section, polishing section and hairbrush Duan Gongsan part from left to right successively, be provided with the scraper of multi-ring annular at cutter hub section outer circumference face, described polishing section outer circumference face is provided with one deck polishing layer, the lateral surface of described hairbrush section is coated with steel wire hairbrush, and the right-hand end of described hairbrush section is also provided with internal thread interface.
Described cutter hub section, polishing section and hairbrush intersegmental part are provided with the limbers of connection, and the middle part of front portion, middle part and the hairbrush section of described cutter hub section is provided with the weep hole that is communicated with limbers and space outerpace.
The cross section of the left end of described cutter hub section is flat mouth taper shape, and the weep hole of described cutter hub section is positioned on the conical surface of conical structure and distributes ringwise multiple.
Described polishing layer is WC hard alloy layer.
The thickness of described polishing layer is 8-12 millimeter.
Described scraper adopts high-carbon steel to make
To sum up, compared with prior art, the beneficial effects of the utility model are: in this oil pipe pipe that the utility model designs, clean cutter, not only cleaning is complete, thorough, and cost is low, easy to clean, long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in accompanying drawing: 1, weep hole; 2, scraper; 3, cutter hub section; 4, limbers; 5, polishing layer; 6, polishing section; 7, hairbrush section; 8, steel wire hairbrush; 9, internal thread interface.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
Referring to Fig. 1, in oil pipe pipe, clean cutter, this cleaning cutter comprises cutter hub section 3, polishing section 6 and hairbrush section 7 totally three parts from left to right successively, be provided with the scraper 2 of multi-ring annular at cutter hub section 3 outer circumference faces, described polishing section 6 outer circumference faces are provided with one deck polishing layer 5, the lateral surface of described hairbrush section 7 is coated with steel wire hairbrush 8, and the right-hand end of described hairbrush section 7 is also provided with internal thread interface 9.
The present embodiment in use, cutter hub section 3 first stretches in oil pipe, the internal thread interface 9 connection of rotating devices of hairbrush section 7 ends drive whole cleaning swivel to move and promote to clean cutter in oil pipes, the scraper 2 on cutter hub section 3 surface in the time rotating just carries out dirt to tube inner wall and scrapes and cut cleaning, after cleaning, polishing section 6 is polished to tube inner wall again, scraper 2 be there is no to the dirt cleaning of cleaning, finally by steel wire hairbrush 8, the dirt scraping is brushed off and tube wall carried out by steel wire hairbrush 8 again again the cleaning work of final sanding and polishing; The present embodiment is by arranging scraper 2, polishing layer 5 and steel wire hairbrush 8, makes the dirt of tube inner wall can be by from tentatively scraping dirt, middle corase grind and completely ground three cleaning processes, not only easy to clean, quick, and clean more thoroughly, clean effect is good.
Embodiment 2:
The present embodiment has done following optimization on the basis of embodiment 1: described cutter hub section 3, polishing section 6 and hairbrush section 7 inside are provided with the limbers 4 of connection, and the middle part of front portion, middle part and the hairbrush section 7 of described cutter hub section 3 is provided with the weep hole 1 that is communicated with limbers 4 and space outerpace.
The limbers 4 of the present embodiment is for passing into decontaminated water, decontaminated water is soaked into and soaks the dirt of inside pipe wall by weep hole 1, can increase cleaning performance, make to clean more complete, also can reduce the damage of structure simultaneously, increase the service life, and weep hole 1 is positioned at the front portion of cutter hub section 3, the middle part of middle part and hairbrush section 7 is can fully mix with dirt for decontaminated water, there will not be the phenomenon of local soaking, decontaminated water also can be used as temperature lowering water use simultaneously, be used for reducing cutter hub section 3, the temperature of polishing section 6 and hairbrush section 7, thereby protection scraper 2, polishing layer 5 and steel wire hairbrush 8.
As preferably, the cross section of the left end of described cutter hub section 3 is flat mouth taper shape, and the weep hole 1 of described cutter hub section 3 is positioned on the conical surface of conical structure and distributes ringwise multiple.Because scraper 2 carries out cleaning to the dirt of inside pipe wall at first, so in order to reach best cleaning performance, reduce the damage of scraper 2 simultaneously, so the left end of cutter hub section 3 arranges the weep hole 1 of multiple annulars, and weep hole 1 is positioned on the conical surface of circular cone, like this, decontaminated water just can evenly be sprayed on inside pipe wall by weep hole 1, and decontaminated water is also more from weep hole 1 amount out, can spot be well soaked into and be soaked, thereby improve cleaning performance.
