SU16602A1 - Apparatus for cleaning sewer pipes and for filtering water - Google Patents

Description

 The invention is intended to clean sewers and filter water by means of an apparatus that has a centrifuge in the shape of double-cut truncated cones with walls, from a double mesh laid with filter material, and a spiral screw that removes dirt from the tubing fluid supplied to it by two propellers, mounted on a common shaft with a spiral screw. An apparatus placed to prevent the ingress of dirt into a casing with openings for withdrawing pressed water is rotated from two electric motors through a gearing system enclosed in hermetic boxes.

In the schematic drawing of FIG. 1 shows a cross section of a sewer pipe with an apparatus installed in it; FIG. 2 is a side view of the apparatus installed in the pipe, and FIG. 3 is a longitudinal section of it.

The mobility apparatus is mounted on 4 wheels, the axes of which rotate in ball bearings 23 and have the ability to move up and down and set

any angle, depending on the location of the walls 24 of the sewer pipe. The apparatus consists of a centrifugal 1 placed inside the casing 14 (Fig. 3), having the form of two truncated cones mated to their foundations and installed with their tips in ball bearings 10. The walls of the centrifuges are made of a copper double mesh fastened together, the space between the walls of which is filled It is a filtering material. Through the centrifuge passes the shaft 6, which lies in the ball-. bearings and 22 and 19 and carrying a spiral screw 2, placed inside the centrifuge, and propellers 5.5, located between the conical bottom of the hull and the iron grid 20, covering the front of the device. The end of the shaft 6 extending beyond the grid 20 is provided with a square 21 for putting on tools with steel brushes (not shown) for cleaning the pipe walls or for loosening hardened dirt. The other end of the shaft 6, which also carries the spiral screw, is enclosed in a pipe 16, flanged to the wall of the box 17 n and connected to a hose 9. intended for removal

All the devices are dirty. At the top:; The devices, above the centrifugal, are placed hermetically sealed korbbki 13, 15 with electric motors 18, rotating the shaft, installed in the bearing bearings 11, 11 and bearing the middle part of the flywheel 8.8, and at the end passed through the garden 12, L2 in the box 17, placed in the last gears 3, 4. The rotational movement is transmitted from the electric motors to the shaft and the transmission 3, and from the last gear 3, mounted on the narrow end of the centrifuge protruding into the box 17. The rotational movement through the gear train 4 is also transmitted with through-holes for the passage of dirt ejected by the coil 2 into the nozzle 16 and the phlang 9, gear 4, transmitting

revision of the shaft 6 with a spiral screw 2 and paddle-b, 5, designed to load the centrifuge sediments from the pipe being cleaned and the message to the recipient movement of the device. In box 16 there is an opening 26, which is closed by a tap and serves to remove water, which flows out of the box 17 through nickname 12. The centrifugal water is removed through openings 7 of the coder’s 14th; pipes. The wire 25 is also supplied to the eleutromotor through a hermetic nipple in the upper part of the apparatus, and in its attachment to the annapaiy it is attached to the hose with 9 special contractions. To reduce the aioinapaTa movement resistance, the hose is provided with cork floats. For the cleaning apparatus is lowered to the bottom of the 24 well, with a tripod having a hook at its apex,

which corresponds to a ring attached to the body of the apparatus.

In order to clean the sewer pipe, the annajiaT is lowered into the well when: whose, if the well is full of dirt, then the device goes down with the net 20 down and, when activated, works in that position until it is gone, B15yu to the bottom of the well, then rearranged to the wheels. If dry water is present in the well, the latter is used by water from the water supply system, and special valves are used to hold the pipe in the pipe. When working

ddparata ejected dirt enters

through P1lang.9 in a cesspool.

to which the other end is screwed. The electromotors of the azzarate, brought in from a portable power station or some other current source, begin to rotate gears 3. 3, .4, 4, and with them the centrifuge and the shaft with helical and propeller screws at a speed of about 1,500 revolutions per minute, with the rotation of the screws a few tens of turns overtakes the rotation of the centrifugal unit. The centrifugal fluid passing through the centrifugal fluid is separated by centrifugal force into water passing through the filter and collecting at the bottom of the casing 14, and the remaining intracentrifugal contaminant picked up by a helical screw, throwing it through the holes in gear 4 into the fitting. and further on the flange 9. The rotating propellers tend to move the apparatus, what power is used to move the latter as it clears the sewer pipe. In the case of clogging of the centrifuge grids, the latter is reversed, and the dirt clogged by the mesh is washed under the pressure of water admitted to the centrofuge through a grease hose. Repair of the apparatus mainly involves changing the filtering material and the internal grid of the centrifuge. The above described apparatus, in addition to demanding cleaning purposes, can, as a portable filter for purifying turbid water in the air, and so on, as well as a permanent filter for mass filtration of water into the aqueduct of the Nuh Stations.

The subject of the patent.

A device for cleaning sewer pipes and water filtration bottoms, characterized by the use of a centrifuge 1, having the form of two adjoining bases of truncated cones, the walls of which are made of double filtering material: 0m and fitted inside with a Jup imus rotation equipped with a spiral screw 2, which is removed from the centrifugal suspended matter (dirt), and the system receives rotational n transducers. a; movement from the electric motor 18 through gear gears 8 and 4, and in which gears 3 s. will rotate centrifuges part 1, a - to rotate horizontal Bajik 6, helix 2 and propellers 5--5, which have a purpose to give the machine forward motion and to load precipitates from the pipe being cleaned into the centrofuge of the pipe being cleaned, gear 4, in which the drive gear has through holes for

Passing the ejected sprinkle 2 dirt into the fitting 16 and the hose 9, and to protect the apparatus from the effects of the dirt, such is placed in the casing 14 Q with openings 7 for the release of squeezed water, while the electric motors 18 and gears 3 and 4 are sealed: If the boxes are 13, 15 and 17.
