Description

one

The invention relates to devices for cleaning liquids from impurities.

A device for cleaning a liquid is known, comprising a housing, units for introducing a liquid and for discharging purified liquid and sediment, as well as settling and filtration chambers with vertical walls and horizontal bottom 1,

The disadvantage of such structures is the low efficiency of their use, due to the presence of a sufficiently large amount of impurities in the liquid exiting the device. I The purpose of the invention is to increase the efficiency of use due to additional purification and removal of precipitates from the filtration chamber.

This goal is achieved in that the filtration chamber is supplied with a vertical partition not reaching the bottom, and the front wall of this chamber is perforated and installed at an angle to the vertical, while at the distance from the front wall the bottom of the filtration chamber is located at an angle to the horizontal.

FIG. 1 shows the device, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The device includes node 1

the input of the initial fluid, the housing 2, consisting of the loading tank 3 formed by the three walls of the housing 2 and the vertical partition 4, on which the lower part is mounted

inclined shield 5. Case 2 is made in the form of walls, the distance between which is downward reduced. : In the lower, narrow part of the device there is a sediment discharge unit, made in the form

the scraper conveyor b, with the drive 7. Behind the loading capacity 3 there is located a settling chamber 8. The filtration chamber is a container 9 located above the scraper conveyor 6. The container 9 is separated from the scraper conveyor zone by a blind oblique bottom 10. From the chamber 8 side of stand 8, the filtration chamber has a perforated oblique wall 11, and the opposite side is a blank vertical wall. Between the wall 11 and the blank vertical wall is a semi-subdivision partition 12. Between the partition

12 and a blank vertical wall

there is a discharge unit for purified liquid, consisting of two vertical overflow shafts 13, interconnected in the lower part of the device by a common chamber 14. The device has a discharge funnel 15 located above the liquid level to which the scraper conveyor 6 fits. a partition 12 and a blank vertical wall, closed with a lid to prevent foreign objects from entering the drain zone of clean liquid.

During operation, the liquid, along with impurities, enters through unit 1 into the storage tank 3 of the device. In it is the deposition of large particles of impurities. Impurities along the walls of the hull, the partition 4 and the inclined shield 5 fall on the scraper conveyor b, which carries them into the settling chamber 8. The presence of space between. by a partition 4, an inclined shield 5 and a conveyor 6, the fine particles of the impurity, which are suspended, are brought into turbulent motion and are deposited on the conveyor 6. In the settling chamber 8, the largest in volume, the flow of fluid is calmed and mainly falling on the conveyor belt b fine particles of impurity. Then go through the liquid perforated sloping wall 11 inside the filtration chamber. The inclined wall 11 serves to introduce liquid into the container 9 and separate large floating objects that have accidentally entered the device along with the liquid, as well as small particles. The above impurities are retained by the edges of the holes, and then fall down onto the scraper conveyor 6. In the filtration chamber, the liquid passes under the submerged partition wall 12 | preventing floating substances from entering the weir that are removed by a special device (not shown). The presence of the slope at the bottom

10 leads to the fact that if impurities get into the filtration tank, these impurities flow down its inclined plane into the chamber 8. Through the overflow, the clarified liquid is poured into two vertical shafts 13 connected in the lower part by the chamber

14, from where the liquid is taken for consumption. The precipitate deposited in all areas of the device is removed completely by the scraper conveyor b. Due to the low speed of the scraper and the presence of a discharge funnel

15, installed well above the liquid level, the sludge is dehydrated in the device when it is loaded into a special container or on a transport conveyor.

The application of the invention allows to simplify the design, reduce the metal consumption and increase reliability and reduce labor costs during the cleaning of waste liquids.
