Abstract
The utility model discloses a double-layer sand falling roller with an iron star circulation mechanism used for casting cleaning and cooling. The double-layer sand falling roller with an iron star circulation mechanism used for casting cleaning and cooling is characterized in that the outer wall of the roller is provided with an inner layer and an outer layer. An impeller which causes an iron star to rotate back is arranged in an interlayer, and an old sand screen hole and an iron star screen hole are arranged on the inner wall of the roller. The rapid and effective separation of a casting and old sand is realized by the utility model. The double-layer sand falling roller with an iron star circulation mechanism has good cleaning effect and quick temperature drop. A cooling water device does not need to be reused, technology cost is lowered, and the quality of the casting is stable and reliable. The utility model can be used for the sand falling cleanness of the casting.
Description
The utility model relates to the cylinder of a kind of casting cleaning, knockout, cooling, particularly a kind of double-deck knockout cylinder with iron star cycling mechanism.
Casting falling sand, cleaning, cooling are a kind of casting falling sand equipment commonly used on foundry's production line.The cylinder of this type of device is single layer enclosure in the prior art, spiral on the inner wall or charging aperture solid accumulation are higher than discharging opening, make an interior casting mold in the process of advancing while rotating, foundry goods and old sand are peeled off knockout, and foundry goods just separates with old sand up to the drum outlet place.Like this, old sand heat energy can not get effective release, be in the condition of high temperature for a long time in the tube, have to spray in cylinder cooling water, to reduce temperature, the foundry goods burnt-in sand is serious also to get rusty rapidly but the result of water spray makes for this reason, follow-up removing surface workload multiplication, and can make the part foundry goods produce local hard spot, cause the casting quality instability, the effect of knockout is undesirable.
The purpose of this utility model is to provide that a kind of casting falling sand is clean, cleaning, good cooling results, the double-deck knockout cylinder of the band iron star cycling mechanism that casting quality is reliable and stable.
The technical solution that realizes the utility model purpose is: a kind of double-deck knockout cylinder with iron star cycling mechanism, and its main body is a chewing gum and bubble gum, an end of cylinder is a charging aperture, the other end is a discharging opening, the centre is a cylindrical cavity, and cavity inner wall is provided with the guiding spiral, it is characterized in that cylinder is a double-decker, in the cavity between inwall and outer wall, be provided with the impeller that the iron star is refluxed,, be provided with the old sand sieve aperture at inner wall of rotary drum, on the inwall of discharging opening one end, be provided with iron star sieve aperture.
Principle of the present utility model is: foundry goods enters cylinder, add the iron star simultaneously, cylinder rotates, foundry goods and old sand begin to peel off, then, removing surface is carried out in foundry goods and iron star bump, friction, because inner wall of rotary drum is provided with the old sand sieve aperture, peel off on the old sand limit, and sift out on the limit, so the old sand amount is successively decreased in the cylinder, can effectively reduce the temperature in the cylinder, the sand amount reduces simultaneously, can make the bump friction better effects if of foundry goods and iron star, refluxes under the effect of the impeller of iron star in two-layer cylinder, can be recycled the service efficiency height.
The utility model compared with prior art can make foundry goods effectively separate with old sand, cast(ing) surface cleaning, good cooling results, the old sand temperature is lower than 70 ℃, needn't spray water in cylinder again, can save equipment investment greatly, and avoided foundry goods burnt-in sand and local chill, casting quality is reliable and stable.
Accompanying drawing is a kind of structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
In conjunction with the accompanying drawings, the double-deck knockout cylinder of band iron star cycling mechanism of the present utility model, its main body is two-layer cylinder (1), one end is charging aperture (2), the other end is discharging opening (3), at the inwall front end of cylinder internal cavity (4), is provided with guiding spiral (5), the rear end is provided with short spiral (12), between inner wall of rotary drum (7) and the outer wall (8), be provided with the impeller (6) that the iron star is refluxed, inwall (7) is provided with old sand sieve aperture (10) and iron star sieve aperture (11), charging aperture one end also is provided with the iron star and promotes the scraper plate (14) that returns, after casting mold (13) enters cylinder, add iron star (9) simultaneously, old sand separates with foundry goods (15), and from old sand sieve aperture (10), sift out, foundry goods moves ahead under the effect of guiding spiral (5), and clashes into the iron star, friction reaches the purpose of clearing up foundry goods, to afterbody, iron star (9) sifts out through iron star sieve aperture (11), enter in the interlayer, and be back to charging aperture, under scraper plate (14) effect through guide vane wheel (6), re-inject in the cylinder (1), enter working cycles.
Claims (2)
