Description

(54) CONTINUOUS ACTION FILTER

This invention relates to a slurry separation technique and can be used for wastewater treatment.

A continuous filter is known that includes a chamber filled with a granular charge, a vertically mounted distribution of the water to be purified, a device for washing and regeneration of the filter charge. The disadvantage of the filter is the low efficiency of washing and regeneration of the filter charge, due to the unstable operation of the system of discharge of the contaminated load, as well as a significant consumption of industrial liquid.

A continuous filter is also known, comprising a chamber filled with a filtering load, a dispenser of treated water coaxially installed inside it, a collector of purified water, a device for washing and regeneration of the filter charge. However, it is noted that the efficiency of washing and regeneration of the filter charge and the significant flow rate of the washing liquid are low.

The purpose of the invention is to increase the efficiency of washing and regenerating the filter charge and reducing the flow rate of the washing liquid. it

is achieved by the fact that the device for washing and regeneration of the filtering loading is complete in the form of serially connected to the chamber of the hydraulic capacitance and hydrocycloia, the cylinder with the radial partitions mounted on the shaft inside it rotatably

Claims (1)

Figure 1 presents the filter, a general view; Fig. 2 shows a section A-A of Fig. The filter consists of a chamber 1, a floating granular charge 2, a nozzle 3 for supplying source water with a perforated cylinder 4 of a distributor of treated water 5, a collection of clarified water 6, a nozzle 7 for draining clear water, 1C1 container 8, an outlet 9 for sampling loading, a supply pipe for washing water 10, an outlet 11 connected to the washer by a hydrocyclone 12. In one tank 8 on the axis J3 there are rational partitions 14. The edges of the partitions 14 are reinforced with sealing materials 15. Bulkheads are equipped with a drive 16. On the cyclone 12, there are fixed a pipe 17 for draining dirty BWW and a cartridge 18, connected to the pipe 19 for returning 01 the washing load to the filter. The continuous action operates as follows. The source water through the nozzle 3 enters the cylinder 4 installed inside the chamber 1, which is lightened in a floating load 2 moving upward under the action of pushing force, through the distributor of treated water 5, the collection of clarified water and the nozzle 7 is discharged to the consumer. Simultaneously with the filing process, the process of washing and regeneration of the load is carried out. Contaminated loading is continuously taken into a cylindrical tank 8 through pipe 9 and a stream of washing water supplied through pipe 10, through pipe 11 is transported to a hydrocyclone 12, where the separation of purified floating load and hazardous washing water occurs. Grun water goes to the drain through the pipe 17, and the washed load through the pipes 18 and 10 is returned to the filter. In this way, the efficiency of the application and regeneration and filtering charge is increased, and the consumption of industrial liquid is also reduced. Claims of the Continuous Filter, comprising a chamber filled with a filter charge, a dispenser of purified water installed inside it, a collector of purified water, a device for washing and regenerating the filter charge, characterized in that the purpose of increasing the efficiency of the washing and regeneration of the filter charge and reducing consumption industrial liquid, the device for washing and regeneration of the filtering stage is made in the form of a cylindrical container connected in series with the chamber STI and hydrocyclone. moreover, the cylindrical container is provided with radial partitions mounted on the shaft inside it rotatably.
