Conventional technology Surface cleaning of objects to be plated or sprayed with molten metal, sand removal from castings, black skin removal and scale removal of other steel plates,
Blast cleaning is preferably used for various surface treatments such as rust removal. For example, shot blasting, which is an example of blast cleaning, involves forcibly spraying fine particles such as iron particles and glass beads formed by directly pouring molten steel into water together with compressed air to clean and finish the surface. It is something to do. A sand blast that blows a mixed fumes of fine sand and compressed air from a nozzle onto an object belongs to this category.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The blast cleaning method including the above-mentioned “shot blast” and “sand blast” (hereinafter, referred to as “polishing” according to the terminology used in the field) is not suitable for iron particles and glass beads. By spraying fine particles onto an object (hereinafter, referred to as "abrasive to be ground"), surface treatment such as sand removal and scale removal is suitably performed. However, after the polishing and cleaning, the surface of the work to be polished is mixed with fine particles used for a series of cleaning work and fine particles that have been peeled off from the work to be polished due to the impact of spraying the fine particles. Adhere to. Therefore, as post-treatment, it is necessary to wipe off these deposits or wash them with water, but this is a laborious task that requires more manual labor than before, and since a large amount of dust is handled, the working environment is poor. there were.

In addition, the work of scraping off the surface of the object with a wire brush, etc., and subsequently cleaning the adhering material manually without the blast cleaning such as the blast cleaning method is also performed at the site. Depends on. For example, in a split mold consisting of an upper mold and a lower mold used in the centrifugal casting method, a coating mold (a kind of mold release material) is applied to the inner surface of the cavity of each mold to promote the mold separation of the cast product. To be done. When the object to be cast is a hollow molded product such as a ball valve, a sand-solidifying core is installed and used in a split mold. Centrifugal casting is performed using such a die, and after the die is divided and the cast product is taken out, the inner surface of the cavity of each die is cleaned for reuse. At this time, since the collapsed core sand remains on the inner surface of the cavity, it is vacuum-sucked by a vacuum cleaner, and the coating mold that is partially peeled off on the inner surface of the cavity is scratched with a wire brush. Although a series of operations for dropping and vacuum suctioning the coating powder that has been generated is required, this improvement has been an urgent need in terms of work efficiency and working environment because it conventionally relies on all manual work.

Then, the first shutter 13a of the inlet 11 is closed (the opening 10 provided in the partition wall 7 is closed by the second shutter 13b), and the polishing / cleaning chamber 8 is sealed, and the polishing / cleaning is started. That is, the mixed fumes of glass beads and high-pressure air are blown from the nozzle 16 onto the inner surface of the cavity 4a which is directed upward of the lower mold 4. At this time, the nozzle 16 is swung in the polishing and sweeping chamber 8 by the swinging mechanism described with reference to FIG. Further, the rotary table 15 is started to rotate horizontally in synchronization with the start of the cleaning, and in combination with the swinging of the nozzle 16, the spraying of the mixed fumes to the cavity 4a is made uniform. In the polishing chamber 8, a large amount of polishing shavings (core sand, coating-type debris, and other dusts) is generated by the polishing, and it is disturbed in the polishing chamber 8 while being mixed with glass beads. However, this is collected in the lower hopper 22 together with the high-pressure air, and is further separated into the fumes and abrasive shavings in the cyclone chamber 24 described above.

When the polishing and cleaning in the polishing and cleaning chamber 8 is completed, the second shutter 13b of the opening 10 provided in the partition wall 7 is opened, the second conveyor 15a in the polishing and cleaning chamber 8 is driven, and the lower mold 4 is moved downstream. Is transferred to the air blowing chamber 9 on the side. At this time, the surface of the lower mold 4 which has been subjected to the polishing is in a state in which the polishing dust composed of the core sand, the coating powder and other dusts described above is attached. Further, synchronously, the inlet 11 of the polishing / sweep chamber 8 is opened, and the next upper mold 3 waiting for the polishing / sweep on the upstream side is carried into the polishing / sweep chamber 8.

The second shutter 13b of the opening 10 is closed (the outlet 12 is the third
(Closed by the shutter 13c), high pressure air is jetted toward the lower mold 4 from the nozzle 17 arranged in the room, whereby the polishing debris and dust attached to the inner surface 4a of the cavity of the lower mold 4 and other outer peripheral surfaces. Effectively blown off. . The blown off polishing shavings and dust are collected in the lower hopper 23 together with the high-pressure air, and are further separated in the cyclone chamber 24 into fumes and polishing shavings. When high-pressure air is jetted from the nozzle 17 toward the lower mold 4 in the air blowing chamber 9, the upper mold 3 carried into the upstream cleaning chamber 8 is also ground and cleaned simultaneously. The nozzles 16 and 17 are urged to oscillate synchronously by the oscillating mechanism.

EFFECTS OF THE INVENTION As described above, in the continuous blasting / air blowing device according to the present invention, the first conveyor for loading the blasting and sweeping object toward the blasting and sweeping chamber, and the object to be wound which is disposed in the blasting and sweeping chamber A second conveyor for carrying in / stopping / carrying out, a third conveyor arranged in the air blowing chamber for carrying in / stopping / carrying out the work to be polished, and carrying out the work to be polished from the air blowing chamber. And a fourth conveyor which is installed on a rotary table horizontally rotatably provided in the second conveyor grinding / cleaning chamber, and each of these conveyor groups is independently operated at a required timing. The third shutter is also configured to be synchronized with the opening. Therefore, it is possible to carry out a series of operations to remove adhering substances by blowing high-pressure air to the adjacent air-blowing chamber and then to carry out a series of operations with high efficiency after the to-be-polished material is ground and swept in the grinding chamber. Moreover, the shutter keeps the sealed state in the polishing chamber and the air blowing chamber during the cleaning work and the high-pressure air spraying work, thereby freeing humans from this kind of complicated work and improving the production efficiency. Can be significantly improved. Moreover, the working environment, which conventionally handles a large amount of dust, can be improved to a favorable environment, and the effect is extremely large.
