Description
Technical field
The present invention relates to one kind irregularly block object screening plant and multistage screening plant.
Background technology
Food service industry, according to the dimensions of product material, to product classificatin level, advantageous product is realized difference and sells,
Increase the profit of enterprise.Product material is classified according to its dimensions simultaneously, advantageous product automatization, intelligentized production, but
It is because the species of raw material is various, shape is well-regulated also irregular material, sieves present skill for regular material
Art is highly developed, but wants gradation sizing to be not easy very much for irregular material, and present traditional method still adopts
The screen cloth of regular shape material is sieved, but because screen cloth is regular shape, material in irregular shape is possible can only
Just can fall into from the mesh of screen cloth rotating to some direction, but existing screening machine is all using the side of stirring or vibrations
Formula carries out, it is impossible to ensure that each material can rotate to the angle of the mesh that just drops, having uncontrollability, therefore cannot ensure
Screening thoroughly it is impossible to ensure the precision of screening.
Content of the invention
The present invention is directed to the deficiencies in the prior art and provides a kind of screening efficiency height, screening precision height, lays occupation of land face
Long-pending little and stackable one kind irregularly block object screening plant and the multistage screening plant laying the multistage laying of formation.
The present invention adopts the following technical scheme that realization: one kind irregularly block object screening plant, parallel sets including two
The screw rod put, described screw rod is horizontally disposed with, and is provided with the baffle plate being not less than height of materials outside the two of two screw rods, described in two pieces
The space that baffle plate and two described screw rods surround constitutes material channel, described material channel along screw feeding direction be provided with import and
Outlet, is provided with the spacing matching with material size to be sieved between two described screw rods, described spacing is screening mouth, two institutes
The direction of rotation stating screw rod is contrary, and direction of rotation prevents material from screening mouth extrusion.
Described baffle plate is obliquely installed, and screw tip is close to and near the setting of screw rod axis in the lower end of described baffle plate.
Two described screw flight minute surfaces are symmetrical arranged, and described screening mouth is the distance between cylindrical for two screw rods bottom footpath.
The distance that two described screw rods spacing in material channel exit is more than screening mouth forms discharging opening.
Described screw rod passes through gear drive.
Described material channel is provided with feed hopper above import, is provided with discharge bucket, below described screening mouth below outlet
It is provided with material-falling hopper.
One kind irregularly block object multistage screening plant, multigroup described screening plant parallel laying shape at grade
Become screening layered, screening layered described in multilamellar lay up and down and upper screening layered outlet connect with the entrance of lower screening layered formed multistage
Screening plant.
On described screening layered, the baffle plate upper end of adjacent screening plant connects.
Described screening layered is fixed on support, and described support is provided with Quick Connect Kit, and adjacent described screening layered passes through
Quick Connect Kit on support connects.
Described screening layered is provided with five layers.
Due to adopting said structure, the present invention cleverly utilizes screw rod to drive material while driving irregular material conveying
Upset characteristic, due to screw rod bottom footpath tangential velocity be less than screw spiral external cylindrical surface tangential velocity, and irregularity because
Its irregular overall dimensions, touches screw rod bottom footpath and screw spiral external cylindrical surface simultaneously, so that irregular bulk
Material touches two kinds of different tangential velocities simultaneously and so that material is produced rotation and roll, and so irregular material is in screw rod
Can rotate along screw rod while upper conveying, when irregular material rotates to will be from when some angle is less than the spacing sieving mouth
Screening mouth drops thus forming screening, and the material being more than screening mouth then drops from outlet with the motion of screw rod, thus completing to sieve
Point, so substantially increase the controllability of screening it is ensured that the efficiency of screening and quality, and using screw rod as spiral shell during screening plant
The direction of bar rotation is also entirely different with the application of common screw rod, because the top of two screw rods is material channel it is ensured that spiral shell
Bar only conveys material, and not pressing materials, while controlling two screw rods to reversely rotate, direction of rotation prevents material from screening mouth
Extrusion, the irregular material being so more than screw clearance can move in material channel always, until the exit of two screw rods, this
The bright exit in two screw rods can arrange one and be more than the gap of irregular material thus facilitating the collection of unsized material,
It is provided with the baffle plate being not less than height of materials outside the two of two screw rods, so ensure that material is at fortune in the range of material channel
Dynamic, prevent material with the motion of screw rod to both sides action, baffle plate is close to screw tip and near the setting of screw rod axis, prevents thing
Material is by screw extruding.
The two screw rods of this device form one group of screening plant, can arrange multigroup screening plant composition sieve at grade
Layering, so greatly improves the efficiency of screening, and the precision that multistage screening plant can sieve as needed and step sizing are come
Set classification quantity, due to using screw rod as screening main body, multistage screening plant lay get up area occupied little, be laminated cloth
If simple and convenient.
Present invention screening driving is by meshed transmission gear, and running part can realize totally-enclosed protection.And spiral shell
Shank diameter, weight are little, and the rotary inertia of its screw rod is less, can be very good to protect motor.
