SU1472099A1 - Method of cleaning tubular filter elements - Google Patents

Abstract

The invention relates to the field of filtration and can be used both for cleaning tubular filter elements and for cleaning the external surfaces of pipes and other long products from contamination. The goal is to improve the quality of cleaning and simplify operation. The device contains brushes fixed in flanges fixed on hollow sinks having collectors divided into upper and lower sections, with the upper sections having nozzles directed upwards at an angle, and lower ones downward at an angle. The device is provided with guides with sliders having grooves communicating with pipelines for supplying the washing liquid and hollow channels through the valve. 1 hp ff, 3 ill.

Description

one

The invention relates to devices for hydromechanical cleaning and can be used to clean tubular filters of sealers, vertical filters of drainage systems of sludge pads and external surfaces of pipes and other long products from contamination.

The purpose of the invention is to increase the quality of cleaning and simplify operation.

FIG. 1 shows a device, a vertical section; in fig. 2 — node I in FIG. ; in fig. 3 shows section A-A in FIG. one.

The device contains a filtering element 1, brushes 2 installed in flanges 3 fixed on c 4, collectors 5, which are separated by a partition 6 at the top 7 and lower 8 sections, alternately communicating with the cavity 9 stoves 4, connected via an overflow valve 10 with pipelines 1 1 supply of washing liquid. Removable nozzles 12 mounted at an angle on the upper sections 7 upwards are mounted on the collector sections 5, downward on the lower 8 sections, and the outlet openings of the nozzles 12 are slotted.

The manifolds 5 with the same direction of the nozzles are interconnected as communicating vessels with pipelines 11, which are transferred to flexible pressure hoses, into which fluid flows from the supply line of the washing liquid through, for example, a valve, i.e. the direction of movement of the hydromechanical cleaner is changed by supplying then in the lower, then in the upper cavity of the collectors. The device is equipped with guides 13 with sliders 14, which are equipped with grooves 15 and connected by channel 16 with pipes 11, which communicate with each other and are connected to inlet valves 10 installed on pipelines II, providing constant lubrication of sliders 14 and guides 13, since the pressure of fluid in the pipeline opens its valve 10. The filter element 1 includes a perforated pipe 17 with a grid 18.

The nozzles 12 have slotted nozzles 19 in order to grip the larger surface of the fi-bluing element 1.

The device works as follows.

In the initial position, the device is in the extreme upper position of the filter element 1.

About WITH

;about

When the washing liquid is supplied to the pipeline connected to the upper section 7 of the collectors 5, due to the reactive force of the thrust generated by the jets of washing liquid when the nozzles 12 flow out, the device begins to move downwards, and the sediment from the filter element 1 is washed away. unwinding speed of flexible hoses. When this occurs, the adhering sediment on the filter element 1 is loosened with a brush 2 and is removed by washing water under pressure leaving the nozzles 12.

The device reaches to the extreme lower position, changes the direction of movement to the opposite by switching, for example, a three-way valve, changing the direction of supply of the washing liquid to the lower sections 8 of the collectors 5. The reactive force of the nozzles 12 raises the device upwards. However, the cleaning process can be repeated. The upward lifting speed of the device is controlled by the diameters of the nozzles 12 of the collector 5 and the pressure of the incoming washing liquid.

When the device moves both up and down, a part of the washing liquid is taken out of the pipelines by means of the inlet valve 10 and the pipelines 11 through channels 16 enters the channels 15 of the sliders 14 and lubricates the guides 13.

When the device is raised to the top position and the feed pump is turned off

The liquid device is fixed in the upper part of the filter element 1. The feasibility of introducing the proposed device is determined by eliminating manual labor during the cleaning of filter elements (pipes, columns, long items) and the elimination of the installation and disassembly of the filter. Improved working conditions, increased productivity, reduced labor intensity.
