专利摘要:
The invention relates to a semi-submergeable rotary screen for separating liquids and solids, in international class B01D 33/38. A substantially horizontal rotary screen comprises a drum formed of a plurality of spaced-apart circumferential wedge-wires and longitudinal supporting members, the supporting members being spaced longitudinally around the circumference of the drum separated by a distance of not less than 75 mm between adjacent supporting members. The circumferential wires are novel on a submerged screen and do not become blocked by fibres and neither will the longitudinal supporting members lead to blockages if sufficiently spaced. The supporting members may be fixed to the base sides of the wedge wires on the inside of the screen drum and preferably have a thickness measured radially of the drum of not less than 15 mm. Usual applications are for industrial waste recovery or separation.

专利说明:

The rotating sieve contains a drum, the horizontal cylindrical screening surface of which is made of spaced parallel wires 1 with a wedge-shaped cross section, located around the circumference of the drum with the formation of individual rings or turns of a spatial spiral. The wires 1 are fixed on the supporting elements, some of which are made in the form of the lifting bars 2, installed from the inner surface of the drum perpendicular to these wires. The drum is provided with a chute 3 for collecting solid particles falling during the rotation of the drum from the lifting bars 2. The chute 3 is installed inside the drum. The end of the drum on the side of the groove is open, and the opposite end is closed by a partition 4 The inlet end of the drum is connected to the wall 5 by means of a seal. In the wall 5 is made holes 6 and 7, limiting the maximum level of 8 sludge in the drum. The rotation of the drum around the horizontal axis 9 is carried out by means of the actuator 10.
The wires 1 with their inner surface are also fastened to the supporting elements x, made in a view; longitudinal with-11 installed between the lifting of the papa-s; 2. The distance between any - -, or HI space elements. It is no less than 75 mm and the head of 1.chuch of the supporting elements, measured on the basis of the Raban, is 15 mm to me, which is reduced by a decrease in the size of the fibers and supporting elements. With the same (the length of the base of the wedge-shaped wire snchechi is larger than the gap i between adjacent wires, and the ratio of the thickness of the wires measured on the radius of the drum and the length of the base of their wedge-shaped term is not less than 2: 1.
One and the drum supports are made in the form of an ocf Euro bearing 1 fixed to the net re, .ic 13 outside the closed end of the drum and a friend as a pair of bearings 14 and 15 fixed on the frame 13 with the possibility of contact with the upper part of the inner surface of the drum .
On the frame 13 with the possibility of contact with the outer surface of the drum is mounted bearing 16, which ensures the fixation of the drum. The bearing 16 is pressed against the drum by means of a spring device 17
The rotation of the drum is carried out from the drive 10 through a chain or belt drive 18, pulley 19, shaft 20
A flushing dispenser 21 is installed over the sieve.
Rotating sieve works as follows.
The processed sludge is introduced into the interior of the drum. When the drum rotates, the fibers in the slurry orient themselves in the direction of the wires. Due to the fact that the dimensions of the wires 1 and the supporting elements are sufficiently large, the fibers extracted from the sludge are not retained or wound on them. Moving along the inner surface of the drum, the fibers are carried upward by the lifting bars 2 and fall under the action of gravity or jets of water from the washing spray 21 to the chute 3.
Constructive execution of the drum supports ensures reliable operation of the sieve with its sufficiently deep immersion into the filtered sludge.
