Background technology
Nice foundry sand also known as electric smelting haydite, using high-quality bauxite as raw material, through technique systems such as calcining, electric smelting, granulation, sub-sieves
Into being the senior substitute of quartz sand, with thermal coefficient of expansion is small, good fluidity, reality of easily pounding, good permeability, surface be smooth, knot
Many advantages, such as structure is fine and close.In casting technique, nice foundry sand can overcome that quartz sand thermal coefficient of expansion is big, casting accuracy is low, scab
Seriously, the shortcomings of sand removal is difficult, greatly improves the quality of casting.
The particle shape of nice foundry sand is spherical or close to spherical, because the spherical diameter of nice foundry sand is not of uniform size, to ensure casting
The close nice foundry sand particle of diameter is classified as peer, it is necessary to the granularity to nice foundry sand is sieved by the quality of part.Due to nice foundry sand
Size is small, and screening difficulty is high, and screening workload is big, and existing screening installation is difficult to accurately and efficiently sieve nice foundry sand.Institute
So that design is a kind of easily and accurately to be sieved to mound fineness of sand and the automatic sand mixing equipment with level, with very heavy
The meaning wanted.
Utility model content
To solve that nice foundry sand screening difficulty is high, screening workload is big, that existing screening installation is difficult to carry out nice foundry sand is accurate,
The problem of high efficiency screening, the purpose of this utility model is to provide a kind of mound fineness of sand with level automatic sand mixing device.
The utility model is achieved through the following technical solutions：Mound fineness of sand matches somebody with somebody level automatic sand mixing device, including
First end plate, the second end plate, the sieve plate being connected between first end plate and the second end plate, the feeding warehouse being arranged on above sieve plate,
And it is arranged on the discharging opening on end plate；At least 2 pieces of above-mentioned sieve plate, the plate face of sieve plate is obliquely installed；Vertically, each piece
Sieve plate is from top to bottom arranged in order, and is less than the sieve plate sieve diameter positioned at upper strata positioned at the sieve plate sieve diameter of lower floor, under being located at
The sieve plate sieve aperture density of layer is more than the sieve plate sieve aperture density positioned at upper strata；The both sides of above-mentioned sieve plate are provided with baffle plate.
Preferably, two pieces of vertically neighbouring above-mentioned sieve plate incline directions are opposite for the utility model；Above-mentioned sieve
Discharging opening is provided with plate low side and end plate connection, above-mentioned discharging opening and above-mentioned sieve plate low side are highly concordant；Above-mentioned feeding warehouse is set
Put in the high-end top of top layer sieve plate.
Preferably, two pieces of vertically neighbouring above-mentioned sieve plate incline directions are identical for the utility model.
Preferably, above-mentioned first end plate is fixedly installed the utility model, and above-mentioned second end plate lower end is provided with lifting platform；It is above-mentioned
Sieve plate is flexibly connected with above-mentioned first end plate by first rotating shaft, and above-mentioned sieve plate passes through the second rotating shaft activity with above-mentioned second end plate
Connection；Close to above-mentioned first end plate, above-mentioned feeding warehouse is arranged on the top of top layer sieve plate；Discharging is provided with above-mentioned second end plate
Mouthful, above-mentioned discharging opening is concordant with above-mentioned height of sieve plate.
The utility model preferably, is equipped with protective cover, above-mentioned protective cover bottom opening on each above-mentioned discharging opening.
The utility model preferably, is equipped with below conveyer belt, bottom sieve plate below each above-mentioned protective cover and is provided with conveyer belt.
Sieve plate is used to accept the nice foundry sand delivered by feeding warehouse, and nice foundry sand is sieved.End plate and baffle group
Into the closing space for surrounding sieve plate surrounding, prevent nice foundry sand from being dropped from sieve plate edge.Sieve plate is vertically arranged in order, and
Each layer sieve plate from top to bottom, its sieve diameter is gradually decreased, and sieve aperture density gradually increases.So, diameter is more than this layer of sieve plate
The nice foundry sand of sieve diameter is retained by this layer of sieve plate, and is slid along the plate face of this layer of sieve plate to discharging opening, is finally fallen from discharging opening
Go out；And diameter drops down onto next layer of sieve plate less than the nice foundry sand of this layer of sieve plate sieve diameter under sieve aperture and further sieved,
Until nice foundry sand is trapped within that layer of sieve plate of the sieve diameter less than nice foundry sand diameter.If nice foundry sand diameter is less than most bottom
Layer sieve plate sieve diameter, then nice foundry sand fallen from the sieve aperture of bottom sieve plate.Therefore, acted on by the screening of sieve plate, mound
Sand is sized multiple classifications for various grain size categories.
Protective cover is respectively provided with the discharging opening of each layer sieve plate, is bounced when preventing nice foundry sand from being dropped out from discharging opening, is deviateed
Predetermined pick-up point.Protective cover bottom opening, then nice foundry sand from discharging opening drop out after enter protective cover, in the stop of protective cover
Under, it can only vertically fall from the opening of protective cover bottom, facilitate staff in predetermined pick-up point to completing screening operation
Nice foundry sand is collected.
It is equipped with below the protective cover of each layer sieve plate below conveyer belt, the sieve plate of the bottom and also is provided with conveyer belt.Screen and be
