Abstract
The utility model relates to a composite vibration mesh screen used for grading granules of material which is difficult to sieve. The utility model is characterized in that a composite vibrator is arranged on a frame in a mode of gapped loose fit, the both ends of the composite vibrator are blocked by baffle plates which are fixed on the frame, and the baffle plates and the composite vibrator are in clearance fit. The utility model has the pronounced advantages of good performance, easy production, long service life, etc. The utility model is ideal sieving equipment for grading the granules of the material which is difficult to sieve.
Description
The utility model relates to a kind of vibration screen, particularly a kind of vibration screen that is used to handle the classification of difficult screened material fine fraction.
The screen cloth that is used to handle the classification of difficult screened material fine fraction in the prior art has: 1) mesh grid: cost is lower, be easy to make, but screening efficiency is very low, and especially when the sticking humidity of the material that is sized was big, fine particle stage material was difficult to saturating sieve.2) helical screens: it is made up of some rifle bars of arranging according to certain rules, and its partition size generally can not be less than 13mm, and hour percent opening is very low in partition size, and maintenance capacity is big.3) string net: be the screen cloth of a kind of performance good treatment difficult screened material fine fraction classification, but it make difficulty, the cost height, service life is very short.4) stub bar screen cloth: the stub bar that it is installed by several rows of cantilever is formed, and its manufacture difficulty is bigger, and cost is higher, and service life is also undesirable.In sum, it is all not ideal enough to be used to handle the screen cloth of difficult screened material fine fraction classification at present.
The purpose of this utility model provides the Composite-vibrating screen-mesh that is used to handle the classification of difficult screened material fine fraction of a kind of function admirable, easy to manufacture, long service life.
The purpose of this utility model is achieved in that multiple oscillator adopts gapped loose fit mode to be installed on the framework, and the two ends of multiple oscillator are blocked by the baffle plate that is fixed on the framework, and plate washer also is a matched in clearance with multiple oscillator.
The purpose of this utility model can also realize by following mode: multiple oscillator is a cylindrical steel rods.
Also be connected with central sill on the framework, multiple oscillator and central sill also are gap loose fit mode.
The multiple installation position of oscillator on framework can be with to be sized the material movement direction parallel or with to be sized the material movement direction vertical.
The utlity model has following advantage: sieve performance is good, and is easy to manufacture, long service life.Because multiple oscillator and framework are gapped loose fit, multiple oscillator can be in the three-dimensional activity, therefore during screening machine work under the drive of screening machine, multiple oscillator both can be done once vibration with screening machine, also can produce secondary vibration, thereby sieve performance is more far better than the screen cloth that only produces once vibration with respect to screening machine.Simultaneously multiple oscillator is upspring during secondary vibration, also can avoid the problem that fractures and damage under the bump of material, thereby prolong service life greatly, and itself is relatively simple for structure, make also to be easy to, thereby cost is also very low.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the left view of Fig. 1
Fig. 3 is that Fig. 1 is along the A-A cutaway view
Form by framework 1, baffle plate 2, multiple oscillator 3, central sill 4 on the utility model structure.Framework 1 is welded into rectangular box by angle steel, and bigger framework can weld several central sills 4 in the centre.Have the hole that multiple oscillator 3 is installed on framework 1 and central sill 4, the size in hole should be slightly than multiple vibrator diameter big (concrete size should be determined according to the character of screening material), to form loosening matched in clearance.Two ends at multiple oscillator 3 has the baffle plate 2 that is fixed on the framework 1 to block, and between baffle plate 2 and the multiple oscillator 3 certain clearance is arranged also, makes multiple oscillator 3 that level of freedom axially also arranged.Multiple oscillator 3 adopts cylindrical steel rods, and the installation position on framework 1 can be with to be sized the material movement direction parallel, also can be with to be sized the material movement direction vertical.
