Abstract
A compound spiral centrifugal separator features that it has a filtrate channel consisting of spiral body, primary spiral blade, secondary spiral blade and spiral isolating blade. The settling separation time of the mixed liquid can be effectively prolonged, and the settling separation in the filtrate channel is carried out in a relatively static state and is not influenced by the speed difference between the rotary drum and the screw conveyor, so that the separation effect is greatly improved.
The method can obtain ideal effect for separating chemical sludge, activated sludge, electroplating waste liquid, monosodium glutamate waste liquid and other suspensions.
Description
The present invention relates to a kind of centrifuge that rotary rotating cylinder is arranged, be mainly used to separate the liquid mixture that has or do not have solia particle.
Existing centrifugal separator, auger conveyor is the helical blade of individual layer, the time of solution sedimentation is subjected to the restriction of conveyor screw length, and since rotating cylinder and spirochetal speed official post the fine sediment of separate and subside mixed thereby the clear liquid that makes discharge muddiness relatively still again.Existing double helix centrifugal separator is a double helix blade arranged side by side, compare with the single-screw blade, but be to add a parallel blade, a big interval two little intervals have been divided into, and two intervals are unimpeded mutually, do not play the effect that prolongs the sedimentation time, do not have creationary practical value than the single-screw blade, these two kinds of structures all can't effectively be separated suspension.
Task of the present invention is to provide a kind of compound screw centrifugal separator, the blade of auger conveyor is improved to filtrate channel, prolonged the time of liquid mixture sedimentation separation, and the sedimentation separation in the filtrate channel is carried out being under the relative static conditions, be not subjected to the influence of speed difference between rotating cylinder and the auger conveyor, separating effect is greatly improved.
The compound screw seperator, be to be provided with topped secondary helical blade on main helical blade in one side of main helical blade, the spiral isolated blade is arranged at the top of secondary helical blade, the cavity that three and conveyor screw constitute is the filtrate channel of an isolation, the cavity outside is the precipitation passage, gap between spiral isolated blade and the main helical blade is the sludge outlet of filtrate channel, and the origin or beginning of filtrate channel has the filtrate inlet, and end has purified liquor outlet.
The inlet of filtrate can directly be opened the import of system filtrate on main helical blade and secondary helical blade, also helical blade, secondary helical blade and spiral isolated blade can be positioned at uncovered inlet of filtrate channel origin or beginning place composition as filtrate, the uncovered baffle plate of establishing at the largest circumference place is made the guiding filtrate flow to usefulness, therefore baffle plate can make the U-shaped shape, to reduce sneaking into of filter residue.

Accompanying drawings most preferred embodiment of the present invention.
The compound screw centrifugal separator is to be provided with topped secondary helical blade 3 on main helical blade 1 in one side of the main helical blade 1 of columniform auger conveyor 4, spiral isolated blade 5 is arranged at the top of secondary helical blade 3, this three and the conveyor screw 23 common cavitys that constitute are filtrate channels 7, and the cavity outside is a precipitation passage 9.Gap between spiral isolated blade 5 and the main helical blade 1 is the sludge outlet 2 of filtrate channel, and the optimum value in its gap is 1～4 millimeter.The origin or beginning of filtrate channel 7 has filtrate inlet 11, and end has purified liquor outlet 13.
The origin or beginning place of filtrate channel 7, the uncovered of main helical blade 1, secondary helical blade 3 and spiral isolated blade 5 compositions is filtrate inlet 11, the uncovered baffle plate 25 of establishing at the largest circumference place, baffle plate can change the size of filtrate inlet, with play a part the guiding filtrate flow to, make filtrate when entering filtrate channel, need to enter filtrate channel to reduce residue to greatest extent through the U-shaped distance, alleviate the burden that filtrate channel separates again, baffle plate 25 can be a flat board, also can be made into the U-shaped shape.
At the most last two main helical blades of circle of filtrate channel 7 and the gap between the spiral isolated blade is zero, and the spiral isolated blade 5 of last lap is to be embedded in the maze trough of conveyor screw labyrinth sheet 21, is having purified liquor outlet 13 on the conveyor screw labyrinth sheet 21 and on the relevant position of the conveyor screw 23 that matches with it.
The opposite side of conveyor screw labyrinth sheet 21 and rear end cap labyrinth sheet 19 match, rear end cap labyrinth sheet 19 is fastened in the rotating cylinder bonnet 17, with the rotating cylinder rotation, conveyor screw labyrinth sheet 21 has speed difference with auger conveyor 6 rotations between conveyor screw labyrinth sheet 21 and rear end cap labyrinth sheet 19 adjacent surfaces.
When spiral isolated blade 5 and main helical blade 1 are perpendicular, i.e. its angle
=90 °, the external diameter of spiral isolated blade 5 is mutually stairstepping less than the external diameter of main helical blade 1.When 180 ° of angles＞
In the time of＞90 °, the external diameter of spiral isolated blade 5 is less than or equal to the maximum outside diameter of main helical blade 1, and the section of spiral isolated blade 5 can make arc shape.
The structure that increases by a filtrate channel on the spiral centrifuge of the auger conveyor that does not have taper is same as the previously described embodiments.
With prior art relatively, advantage of the present invention is:
1, is provided with filtrate channel, through the further sedimentation separation in this passage of the filtrate after the precipitate and separate.
2, the spiral centrifugal seperator with equal length compares, and has prolonged the time of mixed liquor separate and subside.
3, the separation process of filtrate is to be in static relatively state to carry out in the filtrate channel, is not subjected to fast poor influence the between rotating cylinder and the auger conveyor, and separating effect is better.
