Problems solved by technology

[0002] The current traditional method of protecting the inside of the tank from pills, one is to stick rubber pads on the flange of the tank to block the outlet of the branch pipe to prevent the inside of the pills from entering. However, due to the material problem of the rubber pad, the flange There is a certain possibility that the upper part will fall off, and the projectile will drill into the projectile from the gap between the rubber pad and the flange; the second is to add a blind plate (fastened with bolts) to the flange after the rubber pad is pasted on the flange of the tank body. ) protection method, although this method is effective in protecting the projectile, but because the projectile cannot be thrown to the part covered by the bolt after the bolt is installed, it will cause a local missing dead angle and affect the shot blasting effect

Embodiment Construction

[0008] The present invention will be described in detail below with reference to the accompanying drawings.

[0009] In this method, according to the inner diameter of the steel pipe at the branch pipe port, a piece of round steel is processed into the shape shown in the attached figure. The outer diameter of the round steel is 1mm smaller than the inner diameter of the steel pipe. A groove is processed in the middle of the round steel, and the groove is used to assemble the rubber O-ring. , The outer diameter of the O-ring is 1mm larger than the inner diameter of the steel pipe, and the round steel is welded with a steel pipe (2) for easy access. Make the tooling, put the tooling corresponding to the specification of the branch pipe into the inside of the branch pipe and clamp it tightly, and then paste the rubber pad on the flange. When a projectile enters the interior of the branch pipe from the flange and the rubber pad, the projectile can be sucked out with a magnet.

Abstract

The invention relates to a method for protecting the internal of a tank from pill entrance during pill blasting. The method can guarantee that the pill does not enter the internal of the tank during the pill blasting of the tank; and there is no blind angle of missed pill blasting, so the pill blasting effect is guaranteed.

Description

1. Technical field [0001] The invention relates to a method for protecting the interior of a tank from projectiles during shot blasting, specifically for preventing projectiles from remaining inside the tank (the tank is connected with multiple branch pipes welded with steel pipes and flanges) during shot blasting A protective method that affects the later use of the tank, and makes tooling and adopts it. 2. Background technology [0002] The current traditional method of protecting the inside of the tank from pills, one is to stick rubber pads on the flange of the tank to block the outlet of the branch pipe to prevent the inside of the pills from entering. However, due to the material problem of the rubber pad, the flange There is a certain possibility that the upper part will fall off, and the projectile will drill into the projectile from the gap between the rubber pad and the flange; the second is to add a blind plate (fastened with bolts) to the flange after the rubber ...
