Abstract

The utility model discloses a high pressure water sand spraying nozzle which comprises a nozzle noumenon, wherein the upper part of the nozzle noumenon is provided with a sand sucking tube nozzle; the inside of the pipe of the nozzle noumenon close to the inlet end is provided with a water nozzle, an O-shaped rubber sealing ring is arranged between the nozzle noumenon and the water nozzle; the inside of the pipe of the nozzle noumenon close to the outlet end is provided with a mixing nozzle, a cavity is preserved between the mixing nozzle and the water nozzle, the cavity is communicated with the sand sucking tube nozzle, the diameter of the inner pore of the mixing nozzle is the same as the inner diameter of the sand sucking tube nozzle; the outlet end of the nozzle noumenon is provided with a press mixing nozzle nut. The nozzle spray water and sand to the metal surface with high-pressure water instead of the compressed air to fulfill the aim of rust removing and dust removing; therefore, dust pollution can not be caused to the environment, the body health of the stuff is not affected, and the wearing parts in the nozzle can be processed and changed conveniently. Moreover, the nozzle has the advantages of uneasy abrasion and long service life.

Description

The high pressure liquid sandblast nozzle
(1) technical field:
The utility model relates to a kind of nozzle, relates to a kind of high pressure liquid sandblast nozzle particularly.
(2) background technology:
The rust cleaning of existing metal surface comprises nozzle body with nozzle, adopts air sand blower to handle, and this derusting method is that pneumatically is sprayed onto metallic surface with quartz sand, reaches the purpose of removing oxidation on metal surface thing and iron rust by bump.There are several shortcomings in this method: 1, granularity, the proportion to sand has strict requirement, causes sandblast cost height.2, big for environment pollution, the sandblast dust is very big, makes the nozzleman suffer from breathing problem easily.3, sandblast speed is slow.4, nozzle weares and teares easily.
(3) summary of the invention:
Technical problem to be solved in the utility model just provides a kind of high pressure liquid sandblast nozzle, and it replaces compressed air with water under high pressure, make water and sand be sprayed onto the purpose that the metal surface reaches rust cleaning, dedusting simultaneously, and consumable accessory is changed easily.
In order to solve the problems of the technologies described above, the technical solution that the utility model high pressure liquid sandblast nozzle is adopted is such, and it comprises nozzle body, is provided with a sand suction pipe mouth above nozzle body; In the nozzle body pipeline, be provided with (operating) water nozzle, adopt O shape rubber seal between nozzle body and the (operating) water nozzle by entrance point; Be provided with mixing nozzle by the port of export in the nozzle body pipeline, leave cavity between this mixing nozzle and the (operating) water nozzle, this cavity communicates with the sand suction pipe mouth, and the mixing nozzle diameter of bore is identical with sand suction pipe mouth internal diameter; On the nozzle body port of export, also be provided with and press the mixing nozzle nut.
Adopt after the above-mentioned skill scheme, owing to leaving cavity between (operating) water nozzle that is located at two ends in the nozzle body pipeline and the mixing nozzle, this cavity communicates with the sand suction pipe mouth again, when (operating) water nozzle is mapped to mixing nozzle with high pressure water jets, because the variation of water speed and volume, cavity between (operating) water nozzle and the mixing nozzle has just formed the region of no pressure, negative pressure of vacuum is drawn onto mixing nozzle with sand grains by the sand suction pipe mouth, like this, water and sand just are sprayed onto the purpose that the metal surface reaches rust cleaning, dedusting simultaneously, and can not cause dust polluting environment, it is healthy to influence the staff.By regulating the pressure and the flow of water under high pressure, just can reach the needs of the anticorrosion surface treatment requirement of different brackets.In addition, (operating) water nozzle and mixing nozzle are processed, change all very convenient; Adopt the sealing of O shape rubber seal between nozzle body and the (operating) water nozzle, can take the hydraulic pressure self sealss, the big more sealing property of pressure is good more, and O shape rubber seal also can prevent to vacuumize effect because of the gas leakage of leaking influences.
As further improvement of the utility model, described (operating) water nozzle water side and mixing nozzle arrival end are made as mutual coupling and corresponding mutually taper shape, and its angle of taper is equal, and equals the angle of sand suction pipe mouth and nozzle body, and is not more than 45 °.Thus, sand grains directly is drawn onto mixing nozzle by the sand suction pipe mouth, and is unlikely bump cavity inwall on every side, has both increased the flow velocity of water and sand, has prolonged the service life of nozzle again.
Further improve as the utility model, the outlet of described mixing nozzle is tubaeform mouthful, thereby avoids sand impinging mixing nozzle inwall and make its wearing and tearing; In addition, the port of export of described mixing nozzle stretches out presses the outer certain-length of mixing nozzle nut, and anti-sealing and sand wash away nut.
(4) description of drawings:
Fig. 1 is the cutaway view of the utility model high pressure liquid sandblast nozzle specific embodiment.
(5) specific embodiment:
Referring to Fig. 1, the utility model high pressure liquid sandblast nozzle comprises nozzle body 1, is provided with a sand suction pipe mouth 6 above nozzle body 1.Be provided with (operating) water nozzle 2 by entrance point in nozzle body 1 pipeline, the water inlet end of this (operating) water nozzle 2 is provided with round boss, and boss is provided with O shape rubber seal 3, and the effect of sealing ring 3 guarantees the sealing between nozzle body 1 inner-walls of duct and the (operating) water nozzle 2; The end face of (operating) water nozzle 2 water sides is made as taper shape.In order to add big flood speed, the pipeline aperture in (operating) water nozzle 2 bodies dwindles gradually, forms an aperture to the water side.(operating) water nozzle 2 can also take out in the pipeline of nozzle body 1, so that change.And for example shown in Figure 1, in nozzle body 1 pipeline, be provided with mixing nozzle 4 by the port of export, be provided with a cylindrical boss around nozzle body 1 inner-walls of duct, an end of this boss can block (operating) water nozzle 2 when round boss on (operating) water nozzle 2 water inlet ends is connected; The other end can block mixing nozzle 4 when being connected with the entrance point of mixing nozzle 4, makes between (operating) water nozzle 2 and the mixing nozzle 4 and leaves cavity 7, and this cavity 7 communicates with sand suction pipe mouth 6.The arrival end inner-walls of duct of nozzle body 1 is provided with screw thread, and after high-pressure water tap was connected, (operating) water nozzle 2 just was fixed in the pipeline of nozzle body 1.Described mixing nozzle 4 diameter of bores are identical with sand suction pipe mouth 6 internal diameters, and external diameter and nozzle body 1 pipe diameter match, and can take out in the pipeline of nozzle body 1, so that change.The inlet of described mixing nozzle 4 also is made as taper shape, and is complementary with the taper shape of (operating) water nozzle 2 water sides and corresponding mutually, and its angle of taper is equal, and equals the angle between sand suction pipe mouth 6 and the nozzle body 1, and is not more than 45 °.Again as shown in Figure 1, also be provided with on nozzle body 1 port of export and press mixing nozzle nut 5, screw on and press mixing nozzle nut 5, mixing nozzle 4 just is fixed on the port of export in nozzle body 1 pipeline.Make its wearing and tearing for fear of sand impinging mixing nozzle 4 port of export inwalls, the outlet of mixing nozzle 4 is made as tubaeform mouthful.Press mixing nozzle nut 5, the port of export of mixing nozzle 4 also to stretch out pressure mixing nozzle nut 5 outer certain-lengths in order to prevent that sealing and sand wash away.
