Abstract
The utility model discloses a heating furnace coil scale remover, which is applied to removing scales in a heating furnace coil. A scraping plate is disc-shaped; the edge of the disc is provided with a conical surface at an angle of 30-60 degrees; and file grain is processed on the conical surface. A central pipe is welded on the scraping plate; a cylindrical rubber righting sleeve is sleeved on the central pipe; the other end of the rubber righting sleeve is provided with a disc-shaped pushing plate; a nut is fixed on the end part of the central pipe; a bearing is fixed at the other end of the central pipe; a rotary cap is fixed on the outer wall of the bearing and is provided with 3-6 oblique jet holes; and the jet holes are in the same direction. The scale remover has the effects that: when power liquid is jetted out from the jet holes, the rotary cap can be pushed to rotate, and the power liquid is jetted out from the jet holes; and jet forms cutting force to smash scale blocks on the inner wall of a heating furnace coil.
Description
Technical field
The utility model relates to the heating furnace that has coil pipe, and the specific purpose tool of snaking is a kind of heating furnace coil pipe descaler in particularly a kind of heating furnace coil pipe.
Background technology
The heating furnace that has coil pipe used through the long period, in the heating furnace coil pipe, can have one deck incrustation scale.After the fouling, can cause the heating furnace coil pipe to cross the smooth or obstruction of liquid in the heating furnace coil pipe, make the thermal efficiency reduce affects safety production.The method of fouling is a lot of in the cleaning heating furnace coil pipe at present, as: pickling heating furnace coil pipe, mechanical descaling, chemical scale-inhibiting and electronics antiscale etc.Acid washing method must thoroughly be known incrustation scale, and acid solution heavy corrosion heating furnace coil pipe causes the shortening in service life of heating furnace coil pipe.Mechanical descaling's complex process, difficulty is bigger.The chemical method scale inhibition, cost is high, and effect is relatively poor.The electronic method antiscaling effect is not obvious.
The utility model content
The purpose of the utility model is: a kind of heating furnace coil pipe descaler is provided, effectively removes the fouling of heating furnace coil pipe, prolong the service life of heating furnace coil pipe.
The technical scheme that the utility model adopts is: heating furnace coil pipe descaler; Mainly form by central tube, nut, pushing plate, rubber supporting positive cover, scraper plate, turncap and bearing; It is characterized in that: scraper plate is that disc has centre bore; Along the taper seat that 30～60 degree angles are arranged, on taper seat, be processed with cut at disk border, can carry out scraping the remaining dirty piece of coil pipe inwall.Central tube passes the centre bore of scraper plate and is vertically welded on the scraper plate; On central tube, be with cylinder bodily form rubber supporting positive cover, the external diameter of rubber supporting positive cover is identical with the diameter of scraper plate, an end of rubber supporting positive cover and a contacts side surfaces of scraper plate; The other end at the rubber supporting positive cover has discoidal pushing plate, and pushing plate has centre bore, and central tube passes the centre bore of pushing plate; End at central tube is fixed with nut, the nut compressing pushing plate; The other end at central tube is fixed with bearing; On the outer wall of bearing, be fixed with turncap; Turncap is that semicircle is spherical; There is arc surface shape cavity inside; 3～6 oblique jet holes are arranged on turncap, and the direction of spray-hole is consistent, when power fluid can promote the turncap rotation when spray-hole sprays; And power fluid sprays from spray-hole, sprays the formation cutting force and smashes heating furnace coil pipe inwall dirt piece.
In order to help advancing heating furnace coil pipe descaler in coil pipe, to walk, the middle part of described rubber supporting positive cover and pushing plate contact-making surface and scraper plate is fluted.
In order to make the walking better in coil pipe of heating furnace coil pipe descaler, the height sum of the thickness of scraper plate and rubber supporting positive cover equals the diameter of rubber supporting positive cover.
The method for using of summary heating furnace coil pipe descaler.Heating furnace coil pipe descaler is put into the heating furnace coil pipe, in a side direction coil pipe of pushing plate, inject power fluid (water under high pressure), to preceding sliding, scraper plate strikes off coil pipe scaling inside piece to power fluid promotion heating furnace coil pipe descaler in coil pipe.Power fluid gets into the turncap inner chamber through central tube in addition, and from spray-hole ejection chopping coil pipe scaling inside piece, turncap rotation simultaneously, the jet face of the spray-hole ejection High-Pressure Water of expansion.
The beneficial effect of the utility model: the utility model heating furnace coil pipe descaler, can effectively remove the fouling of heating furnace coil pipe, prolong the service life of heating furnace coil pipe.This descaler cost is low, easy to operate, save time, efficiently, safety.It is on probation that No. 1, No. 2 two heating furnaces carry out scale removal, and every heating furnace handles twice, 40 minutes times spent, the heating furnace inlet outlet pressure differential by scale removal before 0.78MPa, reduce to 0.01MPa, effect is very obvious.
