Abstract

The utility model discloses a metallic pipeline inner-wall processing device, comprising one or a plurality of rotary spraying discs, a main shaft which is fixed at the center of the rotary spraying disc and is driven by a motor, a plurality of material spraying holes are arranged at the proper position of the edge of the rotary spraying disc, the center of the main shaft is provided with a material spraying pipeline which is communicated with a plurality of material spraying holes, the inlet of the material spraying pipeline is respectively connected with a high-pressure air pump and a sand grain supplying tank, the main shaft and a driving motor thereof can carry out reciprocating movement along the direction of the axis; the rotary spraying disc is arranged in a metal pipeline and rotates and reciprocates under the function of the main shaft, the air and sand grains provided by the high-pressure air pump and the sand grain supplying tank are mixed and are sprayed on the inner wall of the metal pipeline in a rotating way, concave and convex surfaces are beaten on a wall surface layer by thin sand grains, thereby changing the wall roughness degree in the metal pipeline.

Description

A kind of metal pipe internal wall treating apparatus

Technical field

The utility model belongs to field of metal surface treatment technology, particularly a kind of device that metal pipe internal wall is carried out the processing of application front surface.

Background technology

The water supply, fuel feeding and the steam line that use in daily life at present and the industrial production mostly are metallic conduit, after the use of long period, can produce corrosion at inner-walls of duct, it is used the very big influence of generation, in order to address this problem, normally carry out anticorrosion at present, need before the application inner-walls of duct is handled, rust staining and fouling are removed at inner-walls of duct application special coating, strengthen the roughness on surface simultaneously, improve ADHESION OF PAINTS power.Mostly the existing device that inner-walls of duct is handled is, pipe range less pipeline big at caliber, in the face of the less and pipeline of internal diameter of the pipeline when longer, just is difficult to meet the demands.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind for the treatment of apparatus that is suitable for the smaller and long metallic conduit of internal diameter.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of metal pipe internal wall treating apparatus, it comprises one or more rotation spray dishes, be fixed on rotation spray disk center and by motor-driven main shaft, the appropriate location, edge of described rotation spray dish is provided with a plurality of material spraying holes, the described alignment of shafts is provided with the material spray pipeline, this material spray pipeline and described a plurality of material spraying hole connect, this material spray entrance is connected with high-pressure pump and sand grains service tank respectively, and described main shaft and drive motors thereof can move back and forth on its axis direction.

Described main shaft is horizontal by certain angle.Be equipped with one or more supports on the described main shaft, some bearings are arranged respectively in the plane vertical with main-shaft axis on the support.

The beneficial effects of the utility model are: after rotation spray dish places in the pipeline; rotation and reciprocating under the main shaft effect; gas that high-pressure pump and sand grains service tank are provided and sand grains mix and are rotating and be ejected into inner-walls of duct; tiny sand grains impacts out male and fomale(M﹠F) with the wall top layer; the male and fomale(M﹠F) that produces is relevant with the size of sand grains; select the sand grains of different size, just can change the size of male and fomale(M﹠F), and then change the size of inner-walls of duct surface roughness.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model device.

The specific embodiment

Below in conjunction with specific embodiment the utility model is described in further detail.

With reference to shown in Figure 1, a kind of metal pipe internal wall treating apparatus, it comprises one or more rotation spray dish 1, be fixed on that 1 center is coiled in the rotation spray and by motor-driven main shaft 2, the appropriate location, edge of described rotation spray dish 1 is provided with a plurality of material spraying holes 11, described main shaft 2 centers are provided with material spray pipeline 3, this material spray pipeline 3 connects with described a plurality of material spraying holes 11, these material spray pipeline 3 inlets are connected with high-pressure pump 5 and sand grains service tank 6 respectively, and described main shaft 2 and drive motors thereof can move back and forth on its axis direction; In actual the use, after will rotating spray dish 1 and inserting in institute's metallic conduit to be processed 4, rotation and reciprocating under main shaft 2 effects, perhaps, pending metallic conduit 4 is placed outside the rotation spray dish 1, make metallic conduit 4 rotations and reciprocating, start high-pressure pump 5 and sand grains service tank 6, high-pressure pump 5 provides gases at high pressure in material spray pipeline 3, sand grains service tank 6 provides sand grains in material spray pipeline 3, after fully mixing, the gases at high pressure band the sand grains high velocity jet to metal pipe internal wall, and metal pipe internal wall is carried out surface treatment.

A kind of specific embodiment as the utility model device, described rotation spray dish 1 has three, what be parallel to each other is fixed on the main shaft 2, described main shaft 2 is horizontal by certain angle, preferably be 90 °, the sand grains that is ejected into like this after the metallic conduit just falls under the weight effect, falls into retracting device and reclaims, or carry out the circulatory system and recycle.

Further improvement as the utility model device, be equipped with one or more supports 8 on the described main shaft 2, as specific embodiment, quantity in the accompanying drawing is two, be separately positioned between two rotation spray dishes 1, on the support 8 with the plane of main shaft 2 axis normal in some bearings 81 are arranged respectively, when rotation spray dish 1 enters in the metallic conduit 4, bearing 81 outer wheel faces contact with metallic conduit 4 internal faces, 2 supporting roles of 8 pairs of main shafts of support, when pending pipeline is long, can guarantee that main shaft 2 can not depart from the pipeline main shaft, improve the effect of handling.

The foregoing description is the principle and the effect thereof of the creation of illustrative the utility model only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
