Description

A kind of separating sieve of producing for foundry casting

Technical field

The utility model relates to a kind of automatic sorting sieve, and particularly a kind of automatic sorting sieve of producing for foundry casting, belongs to sorting machine equipment technical field.

Background technology

In foundry casting is produced, the recycling of mould quartz sand need to be made to mould, but in production or transport process, in quartz sand, can sneak into unavoidably larger other block materials or metalwork, if block material or metalwork are sneaked in Mold Making, affect the mechanical strength of mould, if be positioned at the inner surface of mould, also can cause serious quality influence to foundry goods.

Simultaneously because the quartz sand in foundry casting production has certain humidity, make to need in screening process the inclination angle of sieve nest is strengthened and is beneficial to screening, can avoid the delay on sieve nest of quartz sand after screening simultaneously, and larger inclination angle is accelerated the gliding speed of screening materials carrying, the screening time of staying at sieve nest shortens, just must be by the length prolongation of sieve nest in order to increase the time of staying, finally cause the space hold of equipment to become large.

Summary of the invention

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, a kind of automatic sorting sieve of producing for foundry casting is provided, can isolate fast block material or metalwork in Mold Making raw material quartz sand, improve the mechanical strength of mould, avoid block material or sneaking into of metalwork and affect casting quality, this separating sieve can also effectively be avoided because foundry casting quartz sand has humidity simultaneously, and the quartz sand difficult problem that glides in sieve nest after causing separating can reduce the space hold rate of separating sieve simultaneously.

The technical solution adopted in the utility model is as follows:

A kind of separating sieve of producing for foundry casting, comprise support, sieve nest and hopper, described sieve nest is obliquely installed on support, hopper is arranged at the end of the high point of sieve nest, and described sieve nest comprises chute and screen cloth, and the back of described chute is provided with chute shaking device, described screen cloth hangs and is arranged in chute, the end of screen cloth low spot is provided with the end plate of inclination, and the sidepiece of end plate low spot place screen cloth offers coarse fodder outlet, is also provided with screen vibrator on described screen cloth.

Further, described chute shaking device comprises motor, eccentric wheel and controller, and described eccentric wheel is arranged on the output shaft of motor, and described controller is connected and controls the startup of motor and stop with motor.

Described screen vibrator is Pneumatic vibration stick.

The separating sieve of producing for foundry casting of utility model, the stage casing of described screen cloth is provided with striker plate.

The separating sieve of producing for foundry casting of utility model, the inclination angle of described sieve nest is 30-40 °.

The separating sieve of producing for foundry casting of the present utility model, when casting enters after sieve nest by hopper with quartz sand, under the screen vibrator vibrations of sieve nest, realize separating of fines and coarse fodder, fines skids off from chute, and the end plate that coarse fodder is arranged by the sloped-end of screen cloth downside automatically slips into coarse fodder outlet and discharges, the quartz sand of using due to foundry casting has certain humidity, in described chute, may cause downslide difficulty and cause in chute gathering materials, in order to address this problem, the back side of described chute is also provided with chute shaking device, effectively prevent gathering materials in chute by its vibrations, described chute shaking device adopts motor, the technical scheme of eccentric wheel and controller, make the running of chute shaking device adjustable, controlled, and screen vibrator is Pneumatic vibration stick, there is volume little, be convenient to the advantage of installing, the separating sieve of producing for foundry casting of the present utility model, by the design of chute shaking device, avoid the humidity for overcoming quartz sand to cause its downslide not smooth, need to adopt increase sieve nest gradient to realize fully separating of foundry casting quartz sand and other block materials with the scheme that extends sieve nest length, and described in be arranged at the striker plate in screen cloth stage casing can be to the carrying out of sub-sieve material stopping and distributing again, improve the time of staying of raw material on sieve nest.

In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: the described separating sieve of producing for foundry casting, simplicity of design, reliable in structure, can be effectively by block material or metalwork from mould with separating quartz sand, and export in time and discharge by coarse fodder, have advantages of that separating sieve removal efficiency is high, effectively solve that block material or metalwork are sneaked into and the casting die mechanical strength that causes reduces, even affected the potential risk problem of casting quality; The chute shaking device that its chute bottom arranges simultaneously, effectively solved the quartz sand after screening glides difficult in sieve nest, avoid needing to adopt increase sieve nest gradient to realize separating of foundry casting quartz sand and other block materials with the scheme that extends sieve nest length, reduced the space hold rate of equipment.
