Abstract
The invention discloses a special spray nozzle for a pipe external welding seam circulating sand-blasting rust removal device. The special spray nozzle comprises a body and a ring hairbrush which is connected with the body. The ring hairbrush comprises a skeleton and brush hairs which are fixedly arranged on the skeleton. A sand inlet passage and a sand return ring space are arranged in the body. A recovery pipe which is communicated with the sand return ring space is arranged on the body. The ring hairbrush is connected with the body through an elastic connecting sleeve. A foldable part is arranged on the elastic connecting sleeve. The foldable part is arranged between the body and the hairbrush. By using the elastic connecting sleeve with the foldable part to connect the ring hairbrush onto the body, the resistance of the surplus height of a welding seam can be reduced, the continuity and the stability of sand blasting are guaranteed and the rust removal efficiency is improved; by using the bell-mouth-shaped hairbrush structure and enabling the hairbrush head to have a radian matched with pipe diameter, the tightness of abrasive materials is guaranteed, the wastage of the abrasive materials is reduced, the surface cleanness is improved and the surface quality after rust removal is guaranteed.
Description
Technical field
The present invention relates to a kind of shower nozzle of derusting by sandblasting device, particularly relate to a kind of the nozzle specially used of pipeline outside weld circulation derusting by sandblasting device that be used for.
Background technology
Anticorrosive coating is one of effective method of pipeline corrosion protection, and the pipe main body anticorrosive coat is prefabricated in the factory usually, and body surface treatment, execution conditions, coating device and operating procedure etc. can both be controlled well, and the anticorrosive coat quality can be effectively guaranteed.And the preservative treatment of pipeline welding interface; Because the restriction of execution conditions; Must carry out in the open air or in the marine pipe-laying ship; The corrosion-resistanting interpolating port quality of pipeline welding interface receives influence of various factors, like operating environment, construction technology and opening-supplementing material etc., makes repaired mouth become the weakest link of pipeline corrosion protection.
Pipeline especially petroleum pipeline anticorrosion mainly is to be main with FBE, 3LPE and 3LPP anticorrosive coat, and on-the-spot repaired mouth adopts liquid epoxy priming paint, epoxy powder and shrink belt.The same with the requirement of main pipeline in work progress, the outside weld surface sand-blasting is handled, and reaches the requirement of Sa2.5 level, and depth of abrasion pattern is at 50～100 μ m, and to the overlap hacking of body anticorrosive coat, adopts hairbrush to clean out.Adopt Frequency Induction Heating or other heating means pre-heated surface then, brushing primer or dusty spray coat shrink belt at last.
The open abrasive blast equipment of the many employings of present on-the-spot interface derusting by sandblasting, abrasive material is seriously polluted, and surface cleanness does not reach requirement, has a strong impact on the performance of anticorrosive coat.For this reason, a kind of circulation spray sand type derusting device is developed out and is applied in the operation of pipeline corrosion protection field joint construction.This device is made up of two parts; A part is an environmental protection circulation abrasive blasting rust-cleaning machine; It is to utilize compressed air to form the high speed sand flow surface is handled, and utilizes the removable recovery system that reclaims head and be made up of vavuum pump, recovery chamber, cylinder, dust tube and vacuum hose simultaneously, and this system forms a sealed circuit; Can make abrasive material be recovered separation, reach the effect of cleaning surfaces and environmental protection.Another part is supporting with it automatic walking mechanism device, through automatic control system, the abrator head of two symmetries is fixed on the capable frame of U, under the effect of driving force, makes it then along steel shaft at the uniform velocity mobile with radially.In the operation process, following problem occurred: one) because abrator head moves on a circumferencial direction, and on-plane surface causes a large amount of the splashing of abrasive material.Poor sealing performance, the abrasive material rate of recovery is low, and the surface contamination degree is high, does not reach quality requirement.Two) when abrator head walks to the pipe welding seam place, because of the weld reinforcement effect, abrator head and steel tube surface gap are too small, and resistance is bigger in the traveling process, has influenced speed, and causes the overload of automatic movable motor easily, interrupt derusting by sandblasting.In order to cooperate the normal use of circulation abrasive blasting rust-cleaning machine and automatic travelling device thereof, solve above-mentioned two main problems, be badly in need of a kind of abrator head of special use, guarantee rust cleaning efficient and rust cleaning quality.
Summary of the invention
The present invention provides a kind of the nozzle specially used of pipeline outside weld circulation derusting by sandblasting device that be used for for solving the technical problem that exists in the known technology, and this shower nozzle can improve rust cleaning efficient.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind ofly be used for the nozzle specially used of pipeline outside weld circulation derusting by sandblasting device, comprise body and coupled annular hairbrush; Said annular hairbrush comprises skeleton and bristle fixed thereon; Be provided with sand filling passageway in the said body and return the sand annular space, said body is provided with the recovery tube that is connected with said time sand annular space, and said annular hairbrush is connected with said body through the elasticity adapter sleeve; Said elasticity adapter sleeve is provided with the folding part, and said folding part is between said body and said hairbrush.
The end that said elasticity adapter sleeve is connected with said annular hairbrush is a bell mouth shape, and said skeleton is nested on the said elasticity adapter sleeve, and said bristle is outside said horn mouth extends to said elasticity adapter sleeve; The brush of said hairbrush is provided with the radian adaptive with the pipeline radius.
Said elasticity adapter sleeve is processed by elastic rubber material; Said skeleton is made of plastics.
Said bristle is processed by the wear-resisting polypropene fiber.
Advantage and good effect that the present invention has are: the elasticity adapter sleeve that has the folding part through employing is connected the structure on the body with annular hairbrush, can reduce the resistance of weld reinforcement, guarantees the continuity and the stability of sandblast, improves rust cleaning efficient; Hair brush structure through adopting bell mouth shape also makes the hairbrush brush have the radian with the caliber coupling, has guaranteed the sealing of abrasive material, has reduced the waste of abrasive material, has improved surface cleanness, has guaranteed the surface quality of rust cleaning.
