Abstract

The utility model provides a sand outlet for a vibrating screen. Sand grains can be screened, rough sand can be filtered, the sand outlet for the vibrating screen is simple and effective in structure, and the crushing and sand screening quality is effectively improved. The sand outlet for the vibrating screen comprises a bottom plate, a side plate and a front plate, and is characterized in that screen cloth is arranged on the bottom plate; a rough sand discharge pipe is arranged at the lower end of the front plate.

Description

The vibratory sieve mouth that shakes out

Technical field

The utility model relates to the sand preparing machine of casting industry, is specially the vibratory sieve mouth that shakes out.

Background technology

Casting industry can discharge a large amount of solid waste aborning, it is mainly antiquated sand, development along with industry, the extensive use of various organic and inorganic binding agents, cause the harmful components that contain in antiquated sand more and more, residual aldehyde, phenol, benzene, potassium, isocyanide, sulfide etc. in antiquated sand such as organic resin binding agent, harmful composition such as residual alkali, phenol in inorganic binder antiquated sand.The antiquated sand that contains these class harmful components, after discharge, through rainwater etch, its harmful components will be polluted rivers and lakes, even pollute life water source.Antiquated sand is carried out to regeneration; can save valuable fresh sand resource; be conducive to environmental protection; reduce old sand and abandon the environmental pollution causing; reclaimed sand also has anxious thermal expansivity little than fresh sand simultaneously; Heat stability is good; grain shape is tending towards rounding; dihedral coefficient improves, and makes to prepare sand permeability raising, reduces the generation of the casting flaws such as pore and waste product; also be beneficial to and adopt carefully surface accuracy and the quality of the sand raising foundry goods of some; can also obtain larger economic benefit, reduce casting cost, economize on resources.

Pour into a mould cooled casting mold, be transported to shakeout carry out knockout by traveling crane, after placer iron separation, foundry goods is transported to fettling shop, and old sand enters conveyer and is transported in sand storage after magnetic separation.While casting due to old sand, born high temperature, a large amount of old sands cakings, conglomeration, also comprised impurity in old sand, regenerating used is processed, and first will sieve old sand, fragmentation.Vibratory sieve is that a kind of effectively right old sand sieves, the device of fragmentation; vibrating motor produces driving torque; make the certain vibration regularity vibration of sand lump; the vibration under the effect of vibrating motor of sand group, collision, rolling, rubbing and screening; become sand grains and be pooled to the mouth discharge of shaking out; yet the sand grains after screening, fragmentation is appointed and has so been comprised a part of coarse sand, and directly entering next step operation use can affect sand grains quality.

Utility model content

For the problems referred to above, the utility model provides the vibratory sieve mouth that shakes out, and it can sieve sand grains, and coarse sand is filtered off, and it is simple in structure, effective, effectively improves broken, sieve chiltern amount.

Its technical scheme is such: it comprises base plate, side plate and header board, it is characterized in that: on described base plate, be provided with screen cloth, the bottom of described header board is provided with coarse sand discharge pipe.

It is further characterized in that: described base plate is trapezoidal, and described side plate is provided with two, and described side plate, described header board and described base plate surround dustpan shaped;

Described coarse sand discharge pipe is arranged to the semicircle pipeline of evagination on header board;

Described base plate also comprises screen cloth pressing plate and screen cloth base plate, and described screen cloth is arranged between screen cloth pressing plate and screen cloth base plate and by being arranged on the bolt on edge, surrounding and fixes.

The beneficial effects of the utility model are: the sand grains after bolting, fragmentation is pooled to the mouth place that shakes out and takes; the screen cloth of fine sand on base plate falls; coarse sand is stayed on screen cloth; under the effect of gravity, tumble to coarse sand discharge pipe and get rid of; effectively leach coarse sand; it is simple in structure, effective, effectively improves fragmentation, the sieve chiltern amount of vibratory sieve.

Accompanying drawing explanation

Fig. 1 is that master of the present utility model looks schematic diagram;

Fig. 2 is that schematic diagram is looked on a left side of the present utility model;

Fig. 3 is schematic top plan view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

See Fig. 1, Fig. 2, Fig. 3, the utility model comprises base plate 1, side plate 2 and header board 3, base plate 1 is trapezoidal, side plate 2 is provided with two, side plate 2, header board 3 and base plate 1 surround dustpan shaped, and base plate 1 comprises screen cloth pressing plate 4, screen cloth 5 and screen cloth base plate 6, and screen cloth 5 is arranged between screen cloth pressing plate 4 and screen cloth base plate 6, screen cloth pressing plate 4, screen cloth 5 and screen cloth base plate 6 are by being arranged on together with being bolted to of edge, surrounding, and header board 3 lower end evaginations form semicircular coarse sand discharge pipe 7.

Sand grains after bolting, fragmentation is pooled to the mouth place that shakes out and takes; the screen cloth 5 of fine sand on base plate falls; coarse sand is stayed on screen cloth 5; under the effect of gravity, tumble to 7 eliminatings of coarse sand discharge pipe; effectively leach coarse sand; it is simple in structure, effective, effectively improves fragmentation, the sieve chiltern amount of vibratory sieve.
