Abstract

A filter for cleaning water from bulk debris containing a filter surface in the form of a perforated incomplete cylinder, the concave side of which is facing the flow of filtered water and provided with longitudinal radial partitions evenly spaced around the cylinder circumference, forming intake pockets, as well as a suction device for removing accumulated debris, made in the form of a rotary collector placed along the axis of the specified cylinder and connected to the waste line, connected to the suction with a rectangular chamber, equal to the section of the intake pocket, characterized in that the filter surface is placed inside a separate housing having the shape of a cylinder, the axis of which has an eccentricity with respect to the cylinder axis of the filter surface in the direction of movement of the filtered water stream, and the filter surface at the ends is equipped with two lamellar rotation limiters of the suction device.

Description

 rj

partitioned, forming intake pockets, as well as a Mycopaj accumulating suction device for removing the rotary collector placed along the axis of the indicated cylinder and connected to the garbage collection line, connected to a suction chamber of rectangular cross section equal to the cross section in the-pocket, according to the useful In the model, the filtering surface is placed inside a separate housing having the shape of a cylinder, the axis of which has an eccentricity with respect to the axis C1O: Indra of the filtering surface in the direction the movement of the filtered water stream, and the filtering surface at the ends is equipped with two plate-like stoppers for turning the suction device.

Figure 1 shows a filter according to a utility model in longitudinal section, figure 2 is a side view in section along aa of figure 1.

The filter for cleaning water from bulk debris contains a filtering surface in the form of a perforated incomplete cylinder 1, the concave side of which is facing the flow of filtered water (Fig. E) and provided with longitudinal radial partitions 2 uniformly spaced around the cylinder circumference, forming pocket 3, and a suction device for removing incandescent litter litter, made in the form of a rotary collector 5 placed on the axis of the indicated incomplete cylinder 1 and connected to the garbage collection line 4. To perform the rotation, the collector 5 is mounted in bearings 6 (Fig. 1) and connected to the drive shaft 7. The internal cavity of the collector 5 is connected with a tubing of elements 8 with a suction chamber 9 of rectangular cross section equal to the cross-section 1 of the intake pocket 3. The filter surface 1 is placed inside a separate body 10, smoldering the shape of a cylinder, the axis of which smolders the eccentricity of D-50- -20 and ksh (figure 2) with respect to

axis of the incomplete cylinder of the filter surface 1 in the direction of movement of the filtered stream, water. At the ends, the filtering surface 1 is provided with two lamellar stoppers 11 for turning the suction device. The radial angle между between the indicated limiters (the opening angle of the incomplete half cylinder 1) is. The housing is equipped with a pipe 12, 13 for respectively supplying and discharging filtered water. The presence of eccentricity D allows you to simplify the mounting of the filter surface 1 to the housing 10 using the support brackets 14 and organize an intermediate chamber 15 for collecting purified water.

The filter for cleaning water from bulk debris according to a utility model works in the following 11 l manner.

Filtered water enters the filter housing 10 through the pipe IS from the side of the missing part of the incomplete cylinder 1 of the filter surface. Bulk debris is retained on the concave portion of the indicated filter surface, and purified water through the intermediate cooler 15 and the pipe 13 is discharged to the consumer. The accumulation of dirt increases the hydraulic resistance of the filter. When it reaches an unacceptable value, open the valve (not shown) on the garbage collection line 4 and turn on the electric motor (not shown) of the shaft drive 7, as a result of which the manifold 5 with the suction chamber 9 starts to make periodic turns in both directions to the limiters 11 provided with limit switches (not shown in the drawing). When the collector 5 is rotated, the suction cshler 9 continuously passes over all the intake pockets 3, in each of which at the moment of its passage a zone of reduced pressure is created. Under the influence of the resulting pressure drop, water begins to move back through the perforation holes of the filter surface 1, which entrains the contaminants located in the corresponding pocket 3 through the collector 5 and the garbage collection line to the outside, for example, into the drain pipe of the system, to cool the steam turbine condenser (in the drawing not shown).

After the pressure drop across the filter is restored, the collector drive motor 5 returns to normal and the valve on line 4 closes. The presence of intake pockets 3 leads to the fact that the accumulated debris is deprived of freedom of movement along the filter surface until one of the pockets 3 It will be combined with the input section of the mounting chamber 9. At this moment, the entire MVcop located in this intake pocket is disrupted by the reverse water flow. It is possible to rotate the collector bis using a manual drive. Sources of information: 1.
