Abstract
The invention provides a small vibrating screen for recoated sand. The small vibrating screen can fragment and screen semi-finished precoated sand, and has the advantages of simple structure, good effect and efficiency improvement. The small vibrating screen comprises a machine body, a rack and a vibrating motor, and is characterized in that the machine body is fixedly installed on the rack through an elastic support part, the vibration motor is installed at the bottom of the machine body, a screen is arranged in the machine body, the bottom of the machine body is provided with an inclined base plate, and a corresponding sand mouth is arranged on the inclined lower end of the base plate.
Description
Technical field
The present invention relates to the sand preparing machine of casting industry, be specially a kind of precoated sand small vibration sieve.
Background technology
Precoated sand, namely sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, and precoated sand mainly adopts the selected natural siliceous sand of high-quality to be roughing sand, novolac resin, and methenamine and reinforcing agent are raw material.According to the different technical requirements of user, in curing rate, demoulding, mobility, collapsibility, surface finish of casting, storage etc., suitably adjust proportioning.Precoated sand moulding is used in the higher intricate casting of dimension precision requirement, one of optimum shaping materials such as automobile, tractor, hydraulic part, such as, in the casting of engine body etc., along with the development of external machinery industry especially automobile industry, require more and more higher to casting quality, the application that mould covers sand is more and more extensive.
When adopting hot method to mix precoated sand processed, first roughing sand is heated to equably and first roughing sand is heated to 120 ~ 150 DEG C equably, subsequently warmed-up roughing sand and hard resin are added in puddle mixer and mix, to remain in after resin melting on sand grains and to envelope sand grains.To add wherein as curing agent solution in next stage, the evaporation of water produced therefrom makes sand promptly cool, and prevent resin and curing agent from undesirable reaction occurring in puddle mixer, before puddle mixer discharging, calcium stearate is added in puddle mixer to increase the mobile performance of precoated sand.Now in puddle mixer, half-finished precoated sand is easy loose bulk and bulk, and need through processing that is broken, screening, more existing its vibrational power flow of equipment is unreasonable, and crushing effect is not good.
Summary of the invention
For the problems referred to above, the invention provides a kind of precoated sand small vibration sieve, its can broken, sieve half-finished precoated sand, its structure is simple, effective, improves efficiency.
Technical scheme of the present invention is such: it comprises body, frame, vibrating motor, it is characterized in that: described body is fixedly mounted in frame by elastic supporting piece, described vibrating motor is arranged on organism bottom, screen cloth is provided with in described body, described organism bottom is provided with the base plate of oblique setting, and the lower end that described base plate tilts is provided with the mouth that shakes out.
It is further characterized in that: described in the mouth that shakes out be dustpan shaped, described in the mouth that shakes out tilt to establish downward setting, described in the shake out angle of inclination of mouth consistent with the angle of inclination of base plate;
Described elastic supporting piece is stage clip;
Described body inwall surrounding is provided with screen cloth seat, described screen cloth is also provided with screen cloth pressing plate, described screen cloth pressing plate and screen cloth are fixed on screen cloth seat by screen cloth housing pin.
The invention has the beneficial effects as follows: after on knockout to screen cloth, vibrating motor produces driving torque, the vibration regularity vibration making sand lump certain, sand group is vibrated under the effect of vibrating motor, collide, roll, rubbing and screening, become sand grains to fall base plate that screen cloth prolongs inclination and be pooled to the mouth that shakes out and discharge, its structure is simple, effective, improves production efficiency.Adopt spring damping, noise is little, little to frame vibration, extends equipment life.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present invention;
Fig. 2 is schematic side view of the present invention;
Fig. 3 is schematic top plan view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
See Fig. 1, Fig. 2, Fig. 3, the present invention includes it and comprise body 1, frame 2, vibrating motor 3, the flat rectangular body shape of body 1 in opening upwards, body 1 is fixedly mounted in frame 2 by stage clip 4, vibrating motor 3 is arranged on bottom body 1, body 1 inwall surrounding is provided with screen cloth seat 5, screen cloth 6 arranges one deck screen cloth pressing plate 10, screen cloth pressing plate 10 and screen cloth 6 are fixed on screen cloth seat 5 by screen cloth housing pin 7, the base plate 8 of oblique setting is installed bottom body 1, the lower end that corresponding described base plate 8 tilts is provided with the mouth 9 that shakes out, shake out mouth 9 in dustpan shaped, the mouth 9 that shakes out tilts to establish downward setting, the shake out angle of inclination of mouth 9 is consistent with the angle of inclination of base plate 8.
After on knockout to screen cloth 6, vibrating motor 3 starts generation driving torque, the vibration regularity vibration making sand lump certain, sand group is vibrated under the effect of vibrating motor 3, collide, roll, rubbing and screening, become sand grains to fall base plate 8 that screen cloth 6 prolongs inclination and be pooled to the mouth 9 that shakes out and discharge, its structure is simple, effective, improves production efficiency.Adopt stage clip 4 vibration damping, noise is little, vibrates little, extend equipment life to frame 2.Body 1 adopts the design of flat rectangular body shape, makes sand grains expose aerial area and increases, contribute to the cooling of sand grains.
