Abstract

The utility model relates to a regeneration treatment device for casting molding materials, which is characterized in that on the basis of the prior spiral vibratory crusher, a peripheral spiral groove is removed, and a coarse screen and a fine screen are additionally arranged below a grid plate; the coarse screen is used for screening milled coarse slag, and the fine screen is used for screening and separating dust. Because the screens and the grid plate are respectively arranged from bottom to top and can not be limited by the spiral groove, the screening area is large, and the screening process is sufficient; in addition, the regeneration treatment device has the advantages of simpler structure and convenient use and maintenance. The utility model provides an integrated multifunctional sand regenerating device which combines the functions of crushing, screening and dust removing. The whole regeneration treatment processes can be finished by one device to enable the device to have multiple functions. The treatment processes are reduced, the equipment investment is reduced, and the regeneration treatment cost of sand is reduced, thus, the regeneration treatment device can meet the production requirement for regeneration treatment of sand in small foundries.

Description

Integrate crushing and screening and remove the multi-functional sand regenerator of dust

(1) technical field:

Utility model relates to a kind of regeneration treatment facility of casting mould material.

(2) background technology:

In Foundry Production, employed water-glass sand, resin sand, fired mold sand etc., the old sand after the casting sand removal needs regeneration to handle.General in the past way is that these old sands that have piece sand and other foreign material are finished by the production line that can carry out fragmentation, screening, magnetic separation, remove operation such as dust, in processing procedure, also to carry, operation in the middle of the lifting, intermediate storage, feed etc., the equipment complexity, investment and operating cost are very high.Particularly its piece sand of water-glass sand is difficult to fragmentation, and the crushing effect of employed disintegrating machine is relatively poor in the general production line, and incompatible fragmentation regeneration to water-glass sand is produced.For the small-sized Foundry Works that has a large capacity and a wide range, complicated production line obviously is inapplicable.

Existing a kind of spiral vibrating formula disintegrating machine is better to the crushing effect of this old sand, and the efflorescence of not only crushing efficiency height, and sand grains is few.The primary structure of this equipment is that the outside of circular cylinder body that has the spiral conveying groove of rising a periphery is equipped with and is intersected the vibrating motor of installing.The vibrating motor of intersect installing provides spiral vibrating, makes the old sand fragmentation that has piece sand in the drum, and the grid grate plate at the bottom of broken good old sand passes barrel enters the helicla flute of the outer ancient piece of jade, round, flat and with a hole in its centre of staving and sends.Have in order to reduce operation, in the middle of spiral fluted, add screen cloth, so that screen out the assorted slag in the broken sand.This equipment relatively is fit to the particularly harder water-glass sand of cast used sand piece, the break process of resin sand.

But the spiral fluted conveying capacity of said apparatus, limit and hindered the raising of the productivity ratio of equipment, and at the middle Screening Network that adds of helicla flute, because it is shape in the shape of a spiral, device structure complexity not only, the maintenance of installing screen cloth and its all compare difficult, and its sieving area also is restricted, and makes screening efficiency the end of than.And the dust in the sand can not be removed, and still needs follow-up boiling sorting and cleaner to carry out dust separation and handles, and makes production equipment still huger and complicated, can not be fit to small-scale Foundry Works and use.

(3) content of utility model:

The utility model purpose: utility model provides a kind of integrated multifunction sand regenerator that integrates broken, sieves, removes dust exactly for addressing the above problem.Unit can be finished whole regeneration treatment process, one-machine-multi-function.Reduce treatment process, reduce equipment investment, reduce sand regeneration processing cost.The production requirement of handling with the sand regeneration of satisfying small-sized Foundry Works.

The scheme of utility model is: remove peripheral helicla flute on the basis of existing spiral vibrating disintegrating machine, and increase thick, thin twice screen cloth below the grid grate plate, wide-meshed screen is used for screening out broken thick slag, and fine screen mesh is used for screening and separates dust.Because screen cloth and grid grate plate arrange that up and down limited by helicla flute, sieving area is bigger, screening is abundant, and relatively simple for structure, uses easy to maintenance.Thereby can realize one-machine-multi-function.

The basic structure of utility model is: comprise a staving 1, staving is contained on the base 3 by support spring 2, the vibrating motor 4 that pair of cross is installed is housed in the outside of staving, the grid grate plate 5 of level is housed in staving, it is characterized in that: below the grid grate plate, establish wide-meshed screen 6, below wide-meshed screen, establish fine screen mesh 7.

(4) description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a front view of the present utility model.

(5) specific embodiment:

The specific embodiment below in conjunction with the description of drawings utility model, using method and effect: the old sand to be processed that will have piece sand adds in the staving 1, under the intersection vibration effect of vibrating motor, material in the bucket is beated, rotation and flip-flop movement, makes sand lump be subjected to fragmentation, rubbing and abrasive action in motion process; The sand grains that rubs scattered passes the grid grate plate, obtains screening on wide-meshed screen 6, wherein dregs are separated with coarse granule, and by cinder notch 8 eliminatings; The sand that contains dust passes scalping face 6 backs and sieves on dusting cover face 7, and to remove dust wherein, the dust that sifts out is got rid of from the dust outlet of bottom, and the sand grains that sieve is good is discharged from discharging opening 9.Thereby realized integrating broken, screening, removed dust, made the processing of old sand by an equipment just can obtain the reclaimed sand that can directly use, realized one-machine-multi-function.

Because fine screen mesh 7 is damaged easily, for convenient maintenance and replacement, these fine screen mesh 7 usefulness flanges 10 are fixedly mounted on the staving 1, and have carriage 11 to hold fine screen mesh 7 at face off the net.

In order better the dust in the sand to be removed clean and to be avoided escaping and flying upward of in processing procedure dust, can establish dedusting mouth 12 at interlude thick, fine screen mesh, can connect deduster when needed, to obtain better result of use.

Utility model is by improving spiral vibration sand regenerator rational structure, integrate broken, sieve and remove dust, make complicated reclaimed sand processing procedure can finish whole operations with an equipment, one-machine-multi-function, easy to install, for being difficult to of having a large capacity and a wide range realizes that the small-sized Foundry Works of sand reuse provides a kind of less investment, instant effect and simple sand regeneration recovery method.
