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
[0025] The following will be attached Figure 1-4 To further explain the present invention in detail:
[0026] Such as figure 1 As shown, the right and right cover plates 6 of the bell 1 are respectively connected with the directional cover 4 by screws; the liquid inlet tube 7 is fixed on the right cover plate 6 by screws; the number of screws is 24, which can easily adjust the liquid inlet The direction of the liquid outlet C of the pipe, thereby adjusting the direction of the maximum flow output of the spray screen. 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 that can spread to the entire strip width.
[0027] Such as figure 2 As shown, the blade 5 is embedded in the left end hub 8 and the right end hub 9; the left and right end hubs are connected by connecting pins. The number of blades 5 and connecting pins are both 8, whic...

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 spray curtain for strip steel cleaning, which is mainly used in the field of cleaning strip steel surface rust layers in steel plants. Background technique [0002] With the increasingly fierce competition in the steel market, the development of modern industries has increasingly demanding high-quality, high-value-added steel products, and the surface quality of steel plates has become one of the important indicators that manufacturers and users continue to pursue. The abrasive water jet cleaning technology is a new type of strip steel rust layer cleaning technology, which is completed by adding abrasive particles into the high-pressure water jet. [0003] In order to achieve the efficiency of jet crushing, cleaning and cutting, the current domestic and foreign major efforts are devoted to the research of new jet devices and processes; some jets such as cavitation jets, pre-mixed abrasive jets, post-mixed abrasive jets, i...
