Description

A kind of vibrating screen for sawdust screening

Technical field

The present invention relates to screen screening or separating solid materials field.

Background technique

Vibrating screen be in vibrating machine it is with fastest developing speed, industry requirement amount is larger, the more complicated mechanical equipment of structure, work It is to be classified by poroid or gap-shaped working face to granular mixture material of different sizes as principle;Vibrating screen can be with By material screening at finished product (independent screening process), or classification is done for next procedure and prepares (preparation screening process), or Crushing operation provides biggish material particles (auxiliary screening process);Multistage vibration proposed by the present invention for sawdust screening Sieve, can be sieved and be collected to different size of sawdust, can greatly improve the screening efficiency of sawdust.

Summary of the invention

The present invention include motor cabinet, driving disk, pedestal, collect sieve, the sieve of 5mm mesh, 10mm mesh sieve, The sieve of 50mm mesh, slightly clean sieve, fixed baffle, handle, eccentric disc, shaft coupling, motor and rack, and rack fixation is whole Motor is fixed on motor cabinet by a device, and motor drives driving disk that eccentric disc is driven to do periodical rotation by shaft coupling Transhipment is dynamic, and driving disk is connect with pedestal, and being sequentially connected with driving disk is to collect sieve, the sieve of 5mm mesh, 10mm net The sieve in hole, 50mm mesh sieve, slightly clean sieve, and pass through the mating connection of wedge groove and wedge block between each sieve.

So that axis is made rotating motion by motor rotation, drives the biasing post of top to move in a circle around axis, while biasing post Transport motion is done in the straight trough for collecting sieve pedestal, drives sieve to do of reciprocating vibration.

Thick removing miscellany screen mesh is layering Heterogeneous Permutation mode, and effect is to screen out the biggish wooden unit of volume and non-timber impurity.5mm The arrangement mode of the mesh of sieve, 10mm sieve and 50mm sieve makes the distance between each sieve pore center of circle equal, i.e., and any 3 A sieve pore center of circle adjacent to each other is the arrangement mode of equilateral triangle, can make sawdust even drop down.

The sieve of different-diameter sieve pore sieves various sizes of sawdust respectively, if the sieve of 50mm mesh is to weed out to be less than The sawdust of 50mm simultaneously collects the sawdust for being greater than 50mm.

Baffle is fixed on using the cooperation of wedge groove and wedge block by bolt by being fixedly connected between sieve On sieve, the slot cooperation matched on fixed baffle with sieve, vibrating screen can generate a horizontal friction force to come in vibration Each sieve is overcome to want the inertia of relative motion, that is, the power produced relative sliding only has the power of horizontal direction, need to only use one Baffle blocks the movement of sieve, so that it may avoid sieve that opposite sliding occurs, device at work can be efficient, accurate, safety Operation.

It is curved surface on the inside of the handle of sieve, when portable sieve, will not generates too big because of the preponderance of sieve, opponent Load.

There is a motor cabinet between transmission device and sieve, function is the weight for undertaking sieve, passing movement With fixed sieve, does sieve in a fixed plane and vibrate.

Specific embodiment:

The present invention includes motor cabinet (1), driving disk (2), pedestal (3), sieve (5), the 10mm for collecting sieve (4), 5mm mesh The sieve (6) of mesh, the sieve (7) of 50mm mesh, slightly removal of impurities sieve (8), fixed baffle (9), handle (10), eccentric disc (11), motor (13) are fixed to motor by shaft coupling (12), motor (13) and rack (14), the fixed whole device of rack (14) On seat (1), motor (1) drives eccentric disc (11) to do periodic rotational movements by shaft coupling (12) driving driving disk (2), And driving disk (2) is connect with pedestal (3), being sequentially connected with driving disk (2) is the sieve for collecting sieve (4), 5mm mesh (5), the sieve (6) of 10mm mesh, the sieve (7) of 50mm mesh, slightly removal of impurities sieve (8), and pass through wedge groove between each sieve With the mating connection of wedge block.

In order to improve the utilization rate of compass screen surface and the screening efficiency of vibrating screen, the present invention devises a kind of with special sieve pore dress The compass screen surface set, including collect sieve (4), 5mm mesh screening media (5), 10mm mesh screening media (6), 50mm mesh screening media (7), slightly remove Miscellaneous sieve (8) has fixed baffle (9) between each sieve, in order to filter out useful sawdust, needs to clean to sawdust, Finally also the sawdust of screening is collected.

Thick removal of impurities sieve (8) is layering Heterogeneous Permutation mode, and effect is to screen out the biggish wooden unit of volume and non-timber impurity. 5mm mesh screening media (5), 10mm mesh screening media (6), 50mm mesh screening media (7) mesh arrangement mode make each sieve pore center of circle The distance between it is equal, i.e., any 3 sieve pore centers of circle adjacent to each other are the arrangement modes of equilateral triangle, and sawdust can be made equal Even whereabouts.

The sieve of different-diameter sieve pore sieves various sizes of sawdust respectively, if 50mm mesh screening media (7) is to weed out to be less than The sawdust of 50mm simultaneously collects the sawdust for being greater than 50mm.

Being fixedly connected between sieve is consolidated baffle by bolt using the cooperation of wedge groove and a wedge block It is scheduled on sieve, the slot cooperation matched on fixed baffle (9) with sieve, vibrating screen can generate rubbing for horizontal direction in vibration Power is wiped to overcome each sieve to want the inertia of relative motion, that is, the power produced relative sliding only has the power of horizontal direction, only needs The movement of sieve is blocked with a baffle, so that it may avoid sieve from occurring opposite sliding, device at work can efficiently, it is accurate, The operation of safety.

Vibrating screen does of reciprocating vibration, and the axial-rotation of motor (13) is transformed into reciprocating motion, is transported in slot with sliding block Dynamic, eccentric disc makes rotating motion, and band movable slider moves back and forth in slot.

So that axis (16) is made rotating motion by motor rotation, the biasing post (15) of top is driven to do circumference fortune around axis (16) It is dynamic, while biasing post (15) does transport motion in the straight trough for collecting sieve (4) pedestal (3), and sieve (4 ~ 8) is driven to do reciprocal vibration It is dynamic.

It is curved surface on the inside of the handle (10) of sieve, when portable sieve, will not be generated too because of the preponderance of sieve, opponent Big symbol load has added pedestal for fixing (3) to enable sieve to be preferably fixed on sieve on handle, and It is bored on pedestal (3) and has gone up bolt hole, it is corresponding with the bolt hole at sieve both ends, directly handle is bolted when fixed At the both ends of sieve.

There is a motor cabinet (1) between transmission device and sieve, for undertaking the weight of sieve, in transmission device and sieve Intermediation, passing movement are played between son, fixed sieve does sieve in a fixed plane and vibrates.Vibrating screen will be It does and vibrates on desk, is i.e. sliding relatively but also motor is fixed on rack (14) with respect to desk, holding and vibrating screen On reasonable position.
