The utility model relates to a centrifugal equipment used in the separation of solid and liquid, in particular to a plate settling type centrifuge.
Centrifuge is a machine that uses centrifugal force to separate the components of liquid and solid particles or a mixture of liquid and liquid. Centrifuge is mainly used to separate solid particles from liquid in suspension. Or to separate two different densities of non-soluble liquids in the emulsion. According to the characteristics of different density or particle size of solid particles in the liquid settlement rate, sedimentation centrifuge can classify solid particles according to the density or particle size, the particle size is very small from the liquid phase to separate the solid particles. There is no hole on the wall of the sedimentation centrifuge. By centrifugal force, the solid phase in the mixture is stratified according to density or particle size. Density or particle size is concentrated in the drum wall, density or particle size is concentrated in the center, so as to achieve the separation of materials.
However, the skimming device of the existing plate sedimentation centrifuge is controlled by the cylinder, which has complex structure, high production cost, inconvenient maintenance and unsatisfactory separation effect.
Contents of the invention:
The technical problem to be solved by the utility model is to provide a flat plate direct sedimentation centrifuge with simple skimming device structure, low production cost and convenient maintenance.
This is how it works: It includes a flat plate, a shock absorber is fixed on the bottom of the plate, the direct motor is fixed on the plate, the shell is fixed on the top of the shell drum, drum and the power output shaft of the direct motor is connected, the top of the shell is provided with a cover, the upper cover is hinged with the shell, also includes a cover balancer, the upper end of the cover balancer is connected with the upper cover, the lower end of the cover balancer is connected with the plate, The open-cover balancer is arranged outside the shell, and the upper cover is provided with a long hole, a feeding pipe and a skimming device; Its characteristics are: The skimming device comprises a skimming tube and a skimming seat, the skimming tube front end through the cover of the long hole into the drum, the back end of the skimming tube from the skimming seat, the skimming tube is fixed on the cover, the skimming tube is arranged on the outer wall between the thread, the skimming tube and the skimming seat is provided with a silk mother, the first half of the outer wall is fixed on the ring boss, that is, the first half of the diameter of the silk mother, The second half is small in diameter, the mother is installed in the skimming seat, which the ring boss on the mother and the skimming seat wall sliding contact, the lower half of the mother from the skimming seat extended, also includes the ring gland, the ring gland is fixed in the back end of the skimming seat, the ring gland wall and the lower half of the mother sliding contact, is located in the back of the ring gland on the mother is fixed on the hand wheel, The rear of the handwheel is provided with a nut, and the nut is installed with the skimmer pipe thread.
The upper end of the overflow tube extends from the plate into the housing.
The utility model has the advantages that: twist the hand wheel, drive the nut and the screw to rotate, because the ring gland is fixed on the skimming seat, the skimming seat is fixed on the top cover, so the nut and the screw can only rotate can not move axially, the screw and nut rotation drives the skimming pipe to move axially, the skimming pipe completes the process of gradually moving from the center to the drum wall. Its simple structure, low production cost, convenient maintenance, separation effect is good.
