Abstract
An abrasive water jet head for cleaning a rust layer on a metal surface. The main characteristic is that several nozzle holes with inclination angle and non-convergence are distributed on two concentric pitch circles with different diameters and are symmetrically arranged with the central line of the nozzle. After high-pressure water enters the spray head, water jet sprayed out through the small holes on the spray nozzle is distributed in a fan shape, and abrasive can enter the center of the water jet to be strongly mixed with water. The cleaning width of the sprayed abrasive water jet can reach more than 150 mm, the cleaning speed is more than 3 m/min, and the energy is saved by about 35%. The abrasive water jet nozzle is wear-resistant, long in service life, high in cleaning efficiency, energy-saving, capable of automatically sucking dry and wet abrasives, and widely applicable to cleaning, descaling and derusting operations of industrial departments.
Description
The utility model relates to a kind of high-pressure water jet abrasive material cleaning equipment, particularly abrasive waterjet nozzle.
In recent years, utilize the high-pressure water jet cutting metal material and remove the metal surface corrosion layer to have obtained extensive use at home and abroad, abrasive waterjet nozzle has also been carried out deep research thereupon.The notification number that Patent Office of the People's Republic of China announced on April 20th, 1988 is the high efficiency abrasive jetting shower nozzle of CN87207284U, its structure is along the even one group of aperture that distributes of the same circumference on the (operating) water nozzle, from aperture, eject several strands of water jets that the inclination angle is identical, produce negative pressure by effect in the venturi, the suction abrasive material.This nozzle structure can make water jet, and each does not converge.But the shortcoming that this shower nozzle exists is: do not converge convergent cone spray and produce vortex at minimum pitch circle place, the vortex core forms an open circles.After abrasive material sucked hybrid chamber, a part rolled out from vortex, and the abrasive material that rolls out does not mix with water jet, inefficiency; Nozzle is made with common material, under the effect of high-pressure water jet, and quick abrasion; The abrasive jet endoporus is cylindrical, and cleaning width is restricted.
The purpose of this utility model is to provide a kind of the efficient, energy-conservation of fan-shaped water jet, abrasive waterjet nozzle of long service life of producing.
The utility model is realized by following technical proposals.Abrasive waterjet nozzle mainly is made up of high-voltage tube 1, gland 2, abrasive material feed pipe 3, housing 4, (operating) water nozzle 5, adpting flange 6, mixing tube 7, abrasive jet 8, location-plate 10, clamping nut 11 and sealing ring.It is characterized in that having several nozzle bores to be distributed in two concentric pitch circle D on the boss plane of (operating) water nozzle 5
1, D
2On, nozzle bore inlet center is with respect to 1～3 millimeter of (operating) water nozzle 5 axis left and right deviation, and nozzle bore has an angle with the vertical guide of crossing (operating) water nozzle 5 axis, and there is a Long Circle through hole at (operating) water nozzle 5 centers.
The utility model compared with prior art has water jet and abrasive material good mixing effect, cleans effective width and can reach more than 150 millimeters, and cleaning speed is more than 3 meters/minute, can save energy about 35%, and anti-wear performance is good, characteristics such as long service life.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the abrasive waterjet nozzle structure chart.
Fig. 2 is the (operating) water nozzle structure chart.
Fig. 3 is how much motion diagrams of (operating) water nozzle work.
As shown in Figure 1, the utility model is made up of high-voltage tube 1, gland 2, abrasive material feed pipe 3, housing 4, (operating) water nozzle 5, adpting flange 6, mixing tube 7, abrasive jet 8, location-plate 10, clamping nut 11 and sealing ring etc.(see figure 2) is drilled with four nozzle bores on the boss plane of (operating) water nozzle 5, and they are distributed in two concentric pitch circle D that diameter is different
1, D
2On, with the center line symmetric arrangement of (operating) water nozzle 5,1～3 millimeter of aperture inlet center and (operating) water nozzle axis left and right deviation, and also the vertical guide of aperture and mistake (operating) water nozzle axis has an angle, α
1Be 18 °～25 °, α
2It is 10 °～20 °.When water under high pressure through high-voltage tube, enter nozzle cavity after, by the nozzle bore in the (operating) water nozzle 5, enter mixing tube 7 with certain pressure, cause negative pressure, utilize this negative pressure that the abrasive material in the abrasive material feed pipe 3 is sucked in the hybrid chamber 13 and mix, form defibrination through abrasive jet 8 ejections with water under high pressure.The water jet that four apertures on (operating) water nozzle 5 eject is fan-shaped distribution, and each strand jet does not converge, and does not collide, and does not disturb.Because α
1With α
2Existence, formed strong mixed zone F(in the abrasive jet and seen Fig. 3), abrasive material can enter the water jet center and fully mixes with water in the F district.Abrasive grain has been accepted the kinetic energy of water jet, has produced powerful hitting power after the injection corrosion layer of metal surface is disposed.Aperture porch on the (operating) water nozzle 5 is embedded with the ruby 12 that the aperture is 0.5～2.5 millimeter of φ, can reduce the water jet energy loss that causes because of nozzle bore is rough, and can improve 15 times the service life of (operating) water nozzle.The centre bore of (operating) water nozzle 5 is a Long Circle through hole.The endoporus of abrasive jet 8 is a rectangular through holes, and its length-width ratio is 4:1.Adopt said structure to be and cooperate fan-shaped water jet, guarantee effectively to remove width.Be inlaid with combined type hard metal tip 9 on the inner hole wall of abrasive jet 8, strengthened the wearability of abrasive jet, improved service life.
The abrasive waterjet nozzle that the utility model provides can blot certainly, the wet type abrasive material, and the cleaning efficiency height is saved energy, can be widely used in cleaning, de-scaling, the rust cleaning operation of industrial department.
