[0002] Generally, container connecting pipe needs to be welded on cylindrical container, and the current welding method is to open a welding port on the outside of the cylindrical container, then the container connecting pipe is inserted into the welding port, and then the two are welded and fixed. However, after welding by this method, the cylindrical container will collapse at the welding port due to high temperature during welding, resulting in unevenness around the welded part. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide an anti-deformation device for container connecting pipe welding, which can prevent deformation of the container during welding of the container connecting pipe.

[0004] To solve the above technical problems, the technical scheme of the utility model is as follows: an anti-deformation device for container connecting pipe welding, comprising a support frame, two support blocks provided on the lower end of the support frame and supported on the outside of the cylindrical container, a welding port on the cylindrical container between the two support blocks, a connecting screw rod provided on the support frame and screwed, an upper end of the connecting screw rod penetrating the support frame and locked by an upper nut, a temporary connecting pipe for temporary welding of the container connecting pipe fixed on the lower end of the connecting screw rod, and a foreign matter blocking device provided in the container connecting pipe for blocking foreign matter from entering.

[0005] As a preferred scheme, the support block is an arc-shaped block adapted to the shape of the outside of the cylindrical container.

[0006] As a preferred scheme, the support frame comprises a cross beam and two support connecting plates connecting the two ends of the cross beam, the two support connecting plates are arranged in parallel and welded and fixed with the support blocks, and the connecting screw rod penetrates the cross beam and is locked by the upper nut.

[0007] As a preferred scheme, the connecting method of the connecting screw rod and the temporary connecting pipe is that a connecting plate is welded on the upper end of the temporary connecting pipe, the connecting plate is provided with a connecting hole, the connecting screw rod is a double-end screw rod, the lower end of the connecting screw rod penetrates the connecting hole and is locked and fixed by a lower nut.

[0008] As a preferred scheme, the foreign matter blocking device comprises a blocking aluminum film and an elastic snap ring, the blocking aluminum film and the elastic snap ring are arranged inside the container connecting pipe, and the edge of the blocking aluminum film is tightly fixed in the container connecting pipe by the spring snap ring.

[0009] As a preferred scheme, the welding port on the cylindrical container is provided with a 45° welding bevel.

[0010] As a preferred scheme, the outer periphery of the welding port on the cylindrical container is further provided with a reinforcing ring, and the inner hole of the reinforcing ring is also a 45° bevel matched with the welding bevel of the welding hole.

[0011] After the above technical scheme is adopted, the effect of the present application is that: since the anti-deformation device for container nozzle welding comprises a support frame, the lower end of the support frame is provided with two support blocks supported outside the cylindrical container, the welding port on the cylindrical container is between the two support blocks, a connecting screw rod is screw-mounted on the support frame, the upper end of the connecting screw rod penetrates through the support frame and is locked by an upper nut, the lower end of the connecting screw rod is fixed with a temporary nozzle used for temporary welding of the container nozzle, and a foreign matter blocking device is arranged in the container nozzle and used for blocking foreign matters from entering, therefore, when the container nozzle is welded, the container nozzle is tack-welded on the welding port first, then the support blocks on the support frame are placed outside the cylindrical container, and then the foreign matter blocking device is placed in the container nozzle, the container nozzle is temporarily welded with the temporary nozzle, after the welding, the upper nut is rotated to move the connecting screw rod upward to pull and give the welding port a reverse prestress, so that the collapse of the container nozzle and the cylindrical container during welding can be effectively prevented and the deformation of the container can be reduced.

[0012] Since the support blocks are arc-shaped blocks matched with the shape of the outer surface of the cylindrical container, the arc-shaped blocks can better support the outer surface of the cylindrical container, increase the stress area, reduce the indentation of the support blocks on the surface of the container, and support more stably.

[0013] Since the connecting mode of the connecting screw rod and the temporary nozzle is that a connecting plate is welded on the upper end of the temporary nozzle, a connecting hole is arranged on the connecting plate, and the connecting screw rod is a double-end screw rod, the lower end of the connecting screw rod penetrates through the connecting hole and is locked and fixed by a lower nut, after the above connecting mode is adopted, the temporary nozzle can be better connected with the connecting screw rod, and during use, only the lower end of the connecting screw rod needs to be connected to the connecting plate, and then the upper end is fixed on the cross beam, so that the height of the temporary nozzle can be conveniently adjusted for temporary welding with the container nozzle.

[0014] Since the foreign matter blocking device comprises a blocking aluminum film and an elastic snap ring, the blocking aluminum film and the elastic snap ring are arranged in the container nozzle, and the edge of the blocking aluminum film is tightly fixed in the container nozzle by the spring snap ring, the foreign matter blocking device can effectively block foreign matters from entering the container during welding, and of course, the foreign matter blocking device can also prevent foreign matters from entering the container when the temporary weld joint between the temporary nozzle and the container nozzle is cut off.

[0015] Since the welding port on the cylindrical container is provided with a 45° welding bevel, the welding can be more conveniently performed.

[0016] And the outer periphery of the welding joint on the cylindrical container is also provided with a reinforcing ring, the inner hole of the reinforcing ring is also a 45° bevel which is matched with the welding bevel of the welding hole, and the reinforcing ring is also welded together during welding, so that the strength of the surrounding of the welding joint is further improved by using the strength of the reinforcing ring itself, and the phenomenon of collapse of the surrounding of the welding joint of the cylindrical container is avoided.
