Abstract
The utility model provides a technical scheme of a sealing device of a sealed chamber of a shot blasting machine on the inner wall of a steel pipe; the device provided in the scheme comprises a fixing plate, which is circular; a fixing ring is arranged around the fixing plate; a cylinder is arranged at one side of the fixing plate; a plurality of clapboards are arranged in the cylinder; a wearable rubber layer is arranged on the clapboards. The device provided in the scheme has the advantages of being simple in structure, light in weight, good in sealing effect, easy to replace and simple to operate.
Description
Technical field
The utility model relates to a kind of steel pipe inner wall shot-blasting machine, especially a kind of steel pipe inner wall shot-blasting machine closed chamber sealing device.
Background technology
The steel pipe inner wall shot-blasting machine is the bullet of dishing out at a high speed by impeller head, strike is on the surface of steel pipe inner wall, remove the attachment such as oxide skin, welding slag, scab, dirt of inner wall surface, expose the metal true qualities, make inner wall surface present uniform roughness, improve surface corrosion-resistant erosion ability, be more suitable for the aggressive chemistry liquid such as transfer oil after japanning.The steel pipe inner wall shot-blasting machine is a kind of novel shot-blast apparatus that Disa processes for the big or small steel pipe inner wall of difference, it has superpower disposal ability. can select different shot-blasting machine equipment according to the caliber difference of steel pipe, the inner wall of steel cylinder shot-blasting machine adopts fluid motor-driven, and blast cleaning adopts starter to drive.The inner wall of steel cylinder shot-blasting machine adopts automatic ball blast to remove surface corrosion; utilize the High-velocity Projectiles a fluid stream that efficient impeller head is dished out to smash oxide skin, rusty scale and the foreign material thereof on steel pipe internal-surface; make it to obtain meticulous glossy surface; improve tension and the compression strength of workpiece; for the inner surface protection by paints and lacquers increases adhesive force, reach anticorrosion, pillar, the prolongation steel pipe purpose in service life.
During work, make the steel pipe two ends all enter closed chamber.Like this, the front and back closed chamber forms a sealing system together with steel pipe.Effectively avoid the generation of bullet and flour dust overflow phenomenon, all to use cylinder to be sealed at present, cylinder all is stuck in closed chamber, like this for the steel pipe of different tube diameters, need to change different cylinders, waste material and also strengthened cost, and because the large replacing of weight is got up and inconvenience.This is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, and a kind of technical scheme of steel pipe inner wall shot-blasting machine closed chamber sealing device is provided, the apparatus structure of this scheme is simple, and lightweight, good sealing effect, and be easy to change, simple to operate.
This programme is achieved by the following technical measures: a kind of steel pipe inner wall shot-blasting machine closed chamber sealing device, comprise fixed head, the characteristics of this programme are: described fixed head is for circular, the retainer ring that is provided with around fixed head, a side at fixed head is provided with cylinder, be provided with a plurality of dividing plates in cylinder, be provided with the abrasive rubber layer on dividing plate.
Described drum diameter is less than the diameter of fixed head.
Described fixed head is fixed on retainer ring by pressing plate.
Described dividing plate is circular.
Described dividing plate is two.
The junction of described cylinder and fixed head is provided with the ring-shaped rubber layer, and described ring-shaped rubber layer is located at the side of fixed head away from cylinder.
The beneficial effect of this programme can learn according to the narration to such scheme, and owing in this scheme, fixed head being arranged, the fixed head periphery is provided with retainer ring, fixed head can well be fixed on closed chamber like this; The front end of fixed head has cylinder, is provided with dividing plate in cylinder, and the abrasive rubber layer is arranged on dividing plate, can extend like this service life of whole device.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model specific embodiment.
In figure, 1 is fixed head, and 2 is retainer ring, and 3 is cylinder, and 4 is dividing plate, and 5 is the abrasive rubber layer, and 6 is pressing plate, and 7 is the ring-shaped rubber layer.
