Problems solved by technology
[0005] The blade-type curtain spraying machine for strip steel cleaning of the present invention overcomes the above-mentioned deficiencies in the prior art, and it can not only effectively solve the problem of uneven removal of embroidery by the existing spraying technology, but also the nozzle wears quickly and is easy to be blocked, making it difficult to realize continuous sandblasting on a large area The problem of rust removal work, and can realize the dynamic adjustment of the shape and strength of the sprayed slurry curtain, that is, the scope of the cleaning area and the size of the impact force

Embodiment Construction
[0022] The following will be combined with Figure 1-4 The present invention is described in further detail:
[0023] Such as figure 1 As shown, the right side of the bell jar 1 and the right side cover plate 6 are respectively connected to the orientation cover 4 by screws; the liquid inlet pipe 7 is fixed on the right side cover plate 6 by screws; the number of screws is set to 24, which can facilitate the adjustment of the liquid inlet The direction of the pipe outlet C, so as to adjust the direction of the maximum flow rate of the spray screen machine. The center of the liquid inlet pipe 7 is the liquid inlet A, and the outlet direction of the directional cover 4 is the liquid outlet B, so that the sprayed slurry forms a fan-shaped slurry curtain, which can spread to the entire width of the steel strip.
[0024] Such as figure 2 As shown, the blade 5 is embedded in the left hub 8 and the right hub 9; the left and right hubs are connected by connecting pins. The number...

The invention discloses a blade type curtain spraying machine for strip steel cleaning. Slurry mixed through a mixer enters a liquid inlet pipe liquid inlet A, and then is conveyed into the curtain spraying machine through a liquid inlet pipe liquid outlet C, under drive of a high-speed motor, left and right hubs and blades jointly rotate, under the effect of an orientation cover, the slurry can be thrown out at the high speed, a fan-shaped slurry curtain is formed on a fixed-direction liquid outlet B, and then acts on a steel plate, and the aim of removing a strip steel rust layer is achieved; in addition, in the operation process, through changing of the output rotating speed of the motor, the blowing angle between the slurry curtain and the strip steel is adjusted, the blowing force formed through slurry curtain jetting can be adjusted, and the needs of quality of different strip steel surfaces can be met; connecting pins are adopted to connect the left hub and the right hub, the middle-blade embedded mounting manner is adopted, the structure is exquisite and simple, maintaining is facilitated, the variable thickness structure is adopted in the blades, the serviced life of the blades can be prolonged, the jet flow speed can be increased, and work efficiency is improved.
Description
technical field [0001] The invention relates to a blade-type curtain spraying machine for strip steel cleaning, which is mainly used in the field of cleaning the surface rust layer of steel strips in steel mills. Background technique [0002] With the increasingly fierce competition in the steel market and the development of modern industry, the requirements for high-quality and high value-added steel products are becoming increasingly stringent. The surface quality of steel plates has become one of the important indicators that manufacturers and users are constantly pursuing. Abrasive water jet cleaning technology is a new strip steel rust layer cleaning technology, which is completed by adding abrasive particles into high-pressure water jet. [0003] For the working efficiency of jet crushing, cleaning and cutting, at present, domestic and foreign are mainly committed to researching new jet devices and processes; some jets, such as cavitation jet, front mixed abrasive jet,...
