Description

(54) FILTER

one

The invention relates to devices for the purification of liquid from impurities and can be used for the purification of natural and waste waters.

It is known a filtering device containing Kopnyd, a filtering layer and two perforated partition walls: one of which is designed to move 1. | Q

However, the free arrangement of the fibrous filter material between the partitions makes the regeneration of the filter layer unsatisfactory. In addition, the filter capacity | 5 is limited by a filtering area equal to the cross-sectional area of the filter housing.

It is also known that a filtering device 20 consisting of a rigid bottom, filtering material and a movable perforated plate, the shaft of which contains a shock absorber, the shape of which can be changed under the influence of pneumatic or hydraulic devices 2,

The disadvantage of the filter is that the filtration area is limited by the cross-sectional area of the filter. ZO

Closest to the proposed invention is a filter comprising a housing with movable and fixed partitions placed inside it along a height, filtering a LAYER of segments BojrroKOH, fixed with ends on partitions 3.

The upper partition in the apparatus is made with the movement movement, the lower one is attached to the case and the connections connected to the compressed air source are attached to it.

The cleaning of the fluid in the apparatus is carried out by passing the flow to be cleaned through a fibrous layer sandwiched with perforated partitions. The regeneration of the layer is carried out by passing a washing liquid and compressed air through it with a movable partition previously moved upwards.

The disadvantages of such an apparatus are the limited filter area. radios filter cross-sectional area, the degree of purification is low due to the passage of the purified fluid flow along the fibers.

Claims (3)

The purpose of the invention is to increase the filter performance by maximizing the use of ffOBepXHocTH filter fibers and increasing the degree of purification of impurity liquids. This is achieved by the fact that it is equipped with a casing with a pipe for discharging purified water and coaxially installed inside the case on a fixed partition with a perforated container with an upper cone, while 20-50% of the side surface of the case is perforated, around which is placed a casing with a pipe for discharging purified water . Perforated container may have different geometric shapes. So, in the filter housing with a circular cross section, the capacity of the holders is yt. in the form of a circle of perforated tube. The fluid flow in the filter has a transverse radial direction. In a filter with a rectangular cross section, the perforated container is made in the form of a box with a perforated side surface, which divides the housing into two halves and allows two filtering streams to be produced in one housing ... Using the side surface of the building as a filter and installing a perforated container inside the body allows to increase the filtration area, reduce body weight and dissipate cross-filtering, in which the filtering flow is angled to the fixed fibers. common. view cleaning status; Figure 2 is the same as the regeneration state; Figure 3 shows a circular filter with perforated section tanks; Fig. 4 shows the same, straight angle section. The filter includes a housing 1 with a side perforated container 2, a nozzle 3 for supplying the cleaned fluid, a housing with a nozzle 4 for discharging purified water, a nozzle 5 for supplying the washing liquid, a nozzle 6 for contaminating waste, a nozzle 7 for supplying compressed air. Inside the filter housing there is a fixed perforated partition 8 with a perforated pipe 9 fixed on it, a perforated partition 10 attached to a movable rod, fixed on perforated partition fibers 11. The filter works as follows In the cleaning state, the upper partition is moved to the lower position and compresses the fibers to form a coarse layer. The initial fluid is fed into the filter through the pipe 3. Next, the outflow through the perforations of the pipe 9 penetrates into the filtering layer of fibers 11, the pores of which retain the contamination and, and the cleaned liquid removes through the perforations of the lateral surface of the body and the collector with Patrubm 4. When regenerating, the partition 10 is shifted upward and through the pipes and 7, the washing liquid and compressed air are supplied to the housing. Contaminants are led through pipe 6. Thus, by supplying the filter, installed centrally inside the case on the fixed partition, with a perforated container — with a solid upper cone and a casing with a branch pipe for discharging purified water, girdling 20-50% of the side surface: the case, made perforated, an increase in the filter's productivity is achieved compared to the known 1.5-2 times and an increase in the degree of purification of liquids from impurities by 30-50%. Claims of the Invention A filter comprising a housing with movable and fixed partitions placed inside it, a filtering layer of fiber segments fixed with ends on the partitions, characterized in that, in order to increase filter performance by maximizing the use of the filtering surface of the fibers and increasing the degree of purification of liquids from impurities, it is equipped with a casing with a pipe of drainage of purified water and a perforated container coaxially installed inside the case on the fixed partition with the upper cone, while 20-50% of the lateral surface of the body is perforated, around which there is a casing with a branch pipe for drainage of purified water.
