SU1386232A1 - Filter for purifying liquid - Google Patents

Abstract

The invention relates to the purification of liquids from mechanical impurities and fine-fiber soils and reduces the consumption of washing liquid. The filter includes a horizontal cylindrical housing 1, an internal housing 2 with a vertical longitudinal partition on top, immersed with the lower end of the filter loading, nozzles for supplying and discharging the filtered into the washing liquid. When the housing is rotated, its openings are aligned with the inlet and outlet nozzles of the washing machine and mixing of the load, which intensifies its washing. 1 hp f-ly, 2 ill.

The invention relates to the field of filtration of liquids from mechanical impurities and fine-fiber soils and can be used for fine filtration of highly viscous liquid fuel (fuel oil) during its preparation before being fed to the nozzles of the boiler units.

The aim of the invention is to reduce the consumption of washing liquid.

FIG. 1 shows a filter for cleaning the liquid; general view; FIGS. cuts A-A in FIG.

The fluid cleaning filter consists of a robust cylindrical body 1 designed for maximum pressure of working fluid located horizontally, c. installed in it a thin-walled casing 2, having a longitudinal partition 3, attached along a forming shell, inside of which there is a filter filling 4. The volume of the filter filling is not more than half of the internal volume of the casing, and the height of the internal partition 3 is at least 3/4 of the casing diameter . The inner casing is rotated around its axis by means of the device 5, the drive of which is brought out through the stuffing box in the bottom of the FRTR body. On the surface of the casing there are reinforced pipes for supplying the source liquid 6 and draining filtrate 7, pipes for draining sludge and draining the body 8 and for supplying the washing liquid 9.

B. The walls of the casing have holes corresponding to the location of the nozzles and the angles of rotation of the inner casing. The casing 2 is pressed end-on to the nozzles 6 and 7 by means of a spring 1. The holes, filled in to, coincide with the corresponding nozzles of the housing in the position of washing and draining of the washing liquid. The filter works as follows. and then through the opening in the casing wall - inwards into its left part, since during the operating cycle the partition 3 is located at the top of the casing in a vertical position, immersed in the filtering bed no less than 172 of the casing radius, the volume above f ltruyuschey zastkoy into two parts.

at the same time, at the bottom of the casing on both sides of the partition 3, forming a V-shaped passage for the flow of fluid that is being cleaned, the passage through it. The filtrate from the right part of the housing through the patra - side 7 comes out of the filter. When regenerating the filter bed (Figs. 3 and 4), it is necessary to remove sludge with soil particles from the left side through the pipe 8, then, while continuing to turn the casing inside the case clockwise using the device 5, the filter bed is mechanically loosened and agitated. This process is carried out as follows.

When the casing is rotated 180 °, the opening 11 in the casing coincides with the nozzle 8 of the housing drainage and it is emptied. Then the flushing fluid is poured into the casing through the pipe 9 and the casing rotates around the axis continues in the same direction.

the filter bed is poured from the partition, it is actively washed by the washing liquid, and during mechanical collisions of particles the contaminating elements are removed from the surface, the transition is made through the slurry solution. The nozzles are switched when the casing rotates, which plays the role of a spool device. After completion of the filter washing, the inner casing is reset to its original position, at which the baffle on top is immersed in the filter casing.
