Problems solved by technology

[0004] When the shot blasting machine is used to derust the plate, after hitting the plate, the surface of the shot blast is adhered to rust, and the rust is closely attached to the shot blast due to the strong impact between the shot blast and the plate, which is difficult to remove
When the shot blasting with rust attached to the plate collides again, the rust on the shot blasting will adhere to the plate again, reducing the effect of rust removal

Embodiment 1

[0020] Example 1: The rust removal and screening device for recycling shot blasting in this scheme, such as figure 1 As shown, it includes a motor and a ring-shaped containment tube. The containment tube is arranged vertically, and a sieve block 7 is slidingly connected to the containment tube. The containing pipe includes two annular half pipes 4, an annular inner ring stopper 5 is arranged between the two annular half pipes 4, and the two annular half pipes 4 and the inner ring stopper 5 are in sliding connection. A sliding seal, such as a backing ring, is installed between the two annular half pipes 4 and the inner ring baffle 5.

[0021] The screening block 7 is fixed on the inner ring baffle 5, the inner ring baffle 5 is fixed with a first connecting rod 6, the first connecting rod 6 is arranged along the diameter of the receiving pipe, and the first connecting rod 6 is away from the inner ring baffle 5 One end is fixedly connected with a rotating shaft, and the rotating sha...

Embodiment 2

[0025] Example 2: Based on Example 1, such as figure 2 with image 3 As shown, an annular outer ring stopper 9 is also provided between the two annular half pipes 4', and the two annular half pipes 4'and the outer ring stopper 9 are in a sliding connection. A sliding seal, such as a backing ring, is installed between the two annular half pipes 4'and the outer ring stopper 9. The outer ring baffle 9 is fixed on the frame 8', the air outlet 1'is provided on the top of the outer ring baffle 9, and the bottom of the outer ring baffle 9 is provided with an air inlet hole. A second feed port, a second discharge port and a third discharge port are processed on the outer ring baffle 9. The third discharge port is located at the bottom of the outer ring baffle 9. A dust-retaining film is fixedly connected to the outer ring baffle 9 and the area of ​​the dust-retaining film is larger than the diameter of the accommodating pipe. There are several slits along the inner diameter of the c...

Abstract

The invention belongs to the field of auxiliary devices of shot blasting machines, and particularly discloses a rust removal and screening device for recovering blasting shot. The rust removal and screening device comprises an annular holding pipe which is arranged vertically, a screening block is slidably connected into the holding pipe, the holding pipe comprises two annular half pipes, an innerring baffle piece is arranged between two annular half pipes, and the two annular half pipes and the inner ring baffle piece are connected slidably. The screening block is fixed on the inner ring baffle piece, a first connecting rod is fixed to the inner ring baffle piece, and a rotating shaft is fixedly connected to the end, away from the inner ring baffle piece, of the first connecting rod. Therotating shaft and the holding pipe are coaxial, a second connecting rod is rotatably connected to the rotating shaft through a one-way bearing, and the end, away from the rotating shaft, of the second connecting rod is fixedly connected to the two annular half pipes. Air flow can be generated in the holding pipe when the screening block moves, and a plurality of air outlet holes are formed in the holding pipe. According to the rust removal and screening device, by removing rust dust attached to the blasting shot, the effect of removing the rust stain of a product is improved.

Description

Technical field [0001] The invention belongs to the field of auxiliary devices for shot blasting machines, and particularly relates to a shot blasting machine with a screening function. Background technique [0002] Shot blasting means that the shot material is projected onto the working surface at a high speed and at a certain angle through a mechanical method, so that the shot material impacts the working surface, and then inside the machine through the airflow cleaning effect of the matching vacuum cleaner, the shot material and The cleaned up impurities are recovered separately and the pellets can be reused. Compared with other surface treatment technologies, it is faster and more effective. At the same time, the shot blasting machine is used with a dust collector, and the smoke and attachments generated during the working process are recovered and treated in a unified manner, which is more environmentally friendly. [0003] Shot blasting machines are classified into drum type...
