The utility model is characterized in that the drag device and the cutting tool positioner are alternately sheathed on the smutch dredger; the drag device and the cutting tool positioner are fixed on the smutch dredger by a front and a back positioning nuts; the elastic cutting tool is fixed on the cutting tool positioner by an adjusting bolt; an alloy hob is hinged with an elastic cutter frame through a pin shaft; the scale removal diameter can be adjusted through adjusting the bolt up and down. The utility model has the advantages of compact structure, reasonable arrangement of the cutting tool, no dead corner, accurate positioning in the cleanness of large foreign matters, safety, reliability, high efficiency and high speed. In the scale removal process, the scale removal diameter can be automatically adjusted, and the pipe is not clamped and blocked.
Description
The utility model belongs to industrial pig, specifically is a kind of eliminating sludge in pipe equipment.
Mostly present industrial eliminating sludge in pipe equipment is on support to install tool rest and cutter moreover is that a kind of plate-like is scraped knife milling tool.And the support front portion adds universal joint and back-moving spring again, connects resistance circle and bracing ring.The applicant improves at the structure of above descaler, and the application utility model patent, and the patent No. is: ZL98243942.3.But the apparatus for eliminating sludge of this structure is in actual applications, also has following several point defects:
1 scale removal cutter is that polygon is arranged, easily forms the scale removal dead angle, promptly has raceway groove to form.Pipeline section is the profile of tooth dirt, in the scale removal process, easily causes the large tracts of land black dirt to come off, and forms the plugging of dirt heap.
2 facts have proved that universal joint back-moving spring elastic force is added preceding resistance circle for a short time because last lower stress difference causes the offset plate distortion, cause drag device to upwarp, and locate to block at valve and threeway etc.
3 descalers are in the scale removal process, and diameter can not be adjusted.In case dislocation of pipeline counterpart and welding have big overlap, just are stuck.
4 descalers are in the scale removal process, and too big or too many as the place ahead black dirt, incrustation is in heaps, can't destroy black dirt and move ahead, and causes plugging.
The purpose of this utility model is to provide a kind of compact conformation, and the cutter connection and reasonable arrangement does not have the dead angle, the scale removal diameter can be regulated automatically in the scale removal process, does not block and manages not plugging, the accurate positioning of cleaning foreign matter, safe and reliable, scale removal is thorough, fireballing bikini elasticity descaler.
The utility model is to be achieved through the following technical solutions:
Be a kind of eliminating sludge in pipe equipment, this equipment is made up of drag device, black dirt dredge, elasticity cutter, cutter positioning device four parts.It is characterized in that drag device cushion rubber partial fixing in black dirt dredge front portion, the leather cup partial fixing is between two cutter positioning devices; The cutter positioning device is fixed on the black dirt dredge by setscrew nut is alternate with drag device; The elasticity cutter is bolted on the device of cutter positioning by adjustment.
Described drag device is made up of synthetic cushion rubber and rubber cup, and synthetic cushion rubber is preceding, rubber cup after, be installed in black dirt dredge on alternate with drag device.
Described black dirt dredge is made up of hollow shaft and universal elasticity shaft coupling.
Described elasticity cutter is made up of several pieces special alloy hobboing cutters, special type elastic knife rest, bearing pin.
Described cutter positioning device is made up of several pieces polyhedrons, setscrew nut, signal transmitter, alternate being fixed on the black dirt dredge.
The utility model is compared with prior art owing to having adopted drag device, black dirt dredge, elasticity cutter, four kinds of technical equipment of cutter positioning device, so have the following advantages:
1. the safe and reliable not plugging of scale removal snaking.
2. scale removal does not thoroughly have the dead angle, and efficient is fast at a high speed.
3. in the scale removal process, the scale removal diameter is adjusted automatically, does not block pipe.
4. the descaler translation moves ahead, and the cleaning foreign matter is thorough.
5. cutter positioning device configuration signal transmitter is cleared up large-scale foreign matter accurate positionings such as angle steel.
Be described further below in conjunction with accompanying drawing:
Fig. 1: the utility model structure chart
Fig. 2: monolithic descaler profile
Fig. 3: biplate descaler profile
Among the figure: 1 hollow shaft, 2 prelocalization nuts, 3 elasticity synthetic rubber cushion rubbers, 4 pipeline ashes
It is fixed that dirt 5 is adjusted bolt 6 front retainer 7 Elastic tool posts 8 rubber cups 9 backs
Position device 10 back descaler alloy hobboing cutters 11 back setscrew nut 12 leather cup set bolts
Descaler alloy hobboing cutter 15 universal elasticity shaft coupling 16 signals before 13 locating flanges 14
Transmitter 17, preceding descaler alloy hobboing cutter 18, bearing pin
Drag device is alternate with the cutter positioning device as shown in Figure 1 is fixed on the black dirt dredge, front retainer 6 is fixed on the hollow shaft 1, Elastic tool post 7 is fixed on the front retainer 6 by adjusting bolt 5, and preceding descaler alloy hobboing cutter 14 then passes through bearing pin 18 hinged securement with Elastic tool post 7.By universal elasticity shaft coupling 15 front retainer 6 and the back locator 9 that dislocation is fixed on the hollow shaft connected.According to the pipeline actual diameter, by adjusting the adjustment bolt 5 on the Elastic tool post 7, the upper-lower position of descaler alloy hobboing cutter 14 before can adjusting, alloy hobboing cutter scale removal diameter and pipeline actual diameter are complementary, elasticity synthetic rubber cushion rubber 3 is preceding, rubber cup 8 after, prelocalization nut 2 and back setscrew nut 11 will it with front retainer 6 with afterwards on the locator 9 alternate fixation hollow axles.So just descaler can be put into the pipeline that needs scale removal, start pump and open valve, fluid media (medium) promotes the descaler translation and moves ahead, and descaler limit motion alloy hobboing cutter edge tube wall cuts broken black dirt 4.Black dirt between elasticity synthetic rubber cushion rubber 3 and the rubber cup 8 enters hollow shaft 1 by the space of 15 of universal elasticity shaft couplings, is taken away by fluid media (medium), and black dirt can not amass between elasticity synthetic rubber cushion rubber 3 and rubber cup 8 like this.Excessive when the butt joint dislocation of pipeline the place ahead or overlap, at this moment alloy hobboing cutter 14 is subjected to centripetal force, and Elastic tool post 7 entad be out of shape, and along with the pressure increase of fluid media (medium), the scale removal diameter constantly diminishes, till descaler passes through.If there are large-scale foreign matters such as angle steel in the pipeline, scale removal diameter after Elastic tool post 7 distortion still can not pass through, and just is fixed on herein, and at this moment signal transmitter 16 sends signal, pipeline external signal monitor can be received the descaler actual position signal, can locate large-scale foreign matters such as removing angle steel.Because the descaler translation moves ahead, 3 translations of elasticity synthetic rubber cushion rubber promote the place ahead black dirt or other small-sized foreign matter, and it is cleaned out pipeline.If black dirt is piled up, the jet of hollow shaft can wash away it, can plugging.When there is crooked part in pipeline the place ahead, preceding descaler alloy hobboing cutter 14 will be subjected to the pressure of duct wall, drives universal elasticity shaft coupling 15 distortion, and till descaler passed through, bikini elasticity descaler will scale removal in pipeline smoothly like this.
The monolithic descaler has the black dirt dead angle as shown in Figure 2 in addition, and Fig. 3 descaler is the biplate structure, and this phenomenon just can be avoided in no scale removal dead angle, and scale removal forms " bikini ".Because of 3 decision planes, scale removal efficient height not only like this, and do not stay the dead angle, and do not form black dirt and cave in, avoid occurring the plugging phenomenon, safe and reliable, the efficient height.
