Description

Double-mass vibrating mould sand boiling-cooling lathe

Technical field

The present invention relates to molding sand cooling and dedusting device, particularly double-mass vibrating mould sand boiling-cooling lathe that sand casting is used.

Background technology

But dust arrester of layout type sand cooling is all answered in modern sand casting workshop in sand preparing system.The vibration boiling is cooling bed because have the cooling and dedusting function of seething with excitement preferably, usually becomes the first-selected type in the molding sand cooling and dedusting equipment.The boiling cooling chamber is the cooling bed critical piece of vibration boiling.The internal structure of present boiling cooling chamber is: the corrosion resistant plate that the densely covered diameter of employing is the 0.5mm inclined hole is made ebullated bed, and it is horizontally disposed that ebullated bed is.Ruuning situation is: the boiling cooling chamber enters the vibrating transportation state, and molding sand enters the boiling cooling chamber from sand inlet, the displacement of above the ebullated bed of horizontal positioned, seething with excitement, and work of water sprinkling for better material moisture strengthens cooling effect simultaneously.The problem that this structure exists is: the molding sand displacement of seething with excitement above ebullated bed, work of water sprinkling for better material moisture above ebullated bed again, because gravity exists all the time, shut down, when start, shutdown or equipment fault, molding sand takes place directly to contact with the stainless steel counter direction jet trays, cause wet dust more to fill in the stainless steel counter direction jet trays, influence boiling cooling effect; Cause sand grains wearing and tearing stainless steel counter direction jet trays, influence ebullated bed service life; The processing of stainless steel counter direction jet trays is very difficult, and aperture and oblique angle are difficult to reach desirable requirement.

Summary of the invention

The purpose of this invention is to provide a kind of boiling cooling chamber, the porous body of the ebullated bed of this boiling cooling chamber and molding sand remain not contact condition, the porous body of ebullated bed can not worn and not torn by sand grains, the porous body eyelet of ebullated bed can more not filled in by wet dust, the porous body eyelet of ebullated bed is a straight hole, and is easy to process.

Technical scheme of the present invention is a kind of boiling cooling chamber, comprise chamber body, sand inlet, dedusting mouth, sand export, air inlet, its innovative point is: chamber body built-in step type ebullated bed, the cascaded surface of staged ebullated bed is separated into boiling-house and inlet plenum two parts with the chamber body.

Described staged ebullated bed is formed stairstepping by n step plate and porous body.

Described porous body is drilled with densely covered little straight hole, step plate maximum planes horizontal positioned, porous body is embedded between two step plates, when inlaying, the boring direction of porous body is parallel with the step plate maximum planes, the porous body lateral surface is parallel to the step plate vertical plane, slightly step plate vertical plane edge in the indentation

The boiling cooling chamber must dispose the conveying-type vibrational system.Boiling cooling chamber and conveying-type vibrational system have important design relation.Complete design of the present invention is that boiling cooling chamber and two plastid conveying-type vibrational system with staged ebullated bed are combined, and becomes the double-mass vibrating mould sand boiling-cooling lathe that can move.

Double-mass vibrating mould sand boiling-cooling lathe comprises boiling cooling chamber, isolation spring, spring base, vibrating body, vibrating motor, connecting rod and main vibration spring, vibrating motor is packed on the vibrating body, there is main vibration spring to connect between boiling cooling chamber and the vibrating body, also have connecting rod to connect, have isolation spring to connect between vibrating body and the spring base, spring base is installed on the basis.

The seethe with excitement running of cooling chamber of the present invention is described below: under the driving of vibrating motor, the boiling cooling chamber enters vibrational state, return sand and enter boiling-house from sand inlet, drop on the staged ebullated bed, under the vibrating transportation effect, return sand and jumps on step plate and move ahead, and fall at the step plate edge, the process of falling is as sand curtain of formation; Cold wind enters inlet plenum from air inlet, passes porous body, passes the sand curtain that falls again, enters boiling-house, and raises out heat and dust, and heat and dust are drawn boiling-house by the dedusting mouth; Molding sand repeats this process at each step, until shaking sand export.

Technical scheme and running description show: the boiling cooling chamber adopts the staged ebullated bed, and the porous body of staged ebullated bed does not reach molding sand, can not worn and not torn by sand grains, and eyelet can more not filled in by wet dust, and the eyelet of porous body is a straight hole, and boring is convenient.
