Description

The claimed utility model relates to the field of engineering and can be used in the manufacture of water filter separators.

The known design of a self-cleaning filter type "ball in ball" [http://dspace.dstu.education:8080/jspui/bitstream/123456789/677/1/177-183%20Cheban.pdf].

In this filter, water is divided into two streams - the filtrate, which passes through the filter element to the central part of the housing and is discharged through the outlet pipe, and the concentrate, which carries small particles along the walls and discharges them through the drain pipe. The fluid moves along the spherical surface of the housing, as a result of which heavy particles are pressed against the outer edge of the channel without contacting the filter element. The disadvantage of this design is the possibility of heavy particles entering the filtrate smaller than the perforation cells during the start of work, until the movement of water around the circle is established.

The known design of the filter FSC, developed in the research and production LLC "Oceanashenergoe" [http://oceanmas.dp.ua/others/fsc.html].

In this filter, water passes through a coarse screen that traps large particles, and enters the central part of the housing, passes through a fine screen that traps small particles, and is discharged through the outlet pipe. The design of such a filter also provides for a vertical drain pipe with two nozzles located along the axis of the filter housing. When the cleaning mode is activated, the electric drive installed on the upper part of the housing rotates the drain pipe and the coarse screen, so that all particles stopped on the walls of the filter elements are removed through the drain pipes.

The described technical solution also has disadvantages. Firstly, the complexity of manufacturing this filter leads to high cost. Secondly, due to the presence of moving parts inside the filter housing, there is a likelihood of their jamming and the reliability of the cleaner.

Closest to the presented technical solution is the DF-40 dual filter manufactured by Dango & Dienenthal [http://www.dds-filter.com/en/filter/sdvoennyy-filtr-tip-df-40].

This filter consists of two symmetrical cylindrical half-shells, in each of which a filter element is installed, a separation tee at the inlet and a mixing tee at the outlet.

During operation of the filter, a three-way valve at the inlet directs the entire flow of water into one half-housing, in which the liquid is cleaned of impurities and exits through the outlet pipe into the mixing tee and then goes to consumers. In the case of severe contamination of the filter surface of the first half-housing, the three-way valve bypasses the flow to the second half-housing, in which the water continues to be purified while the filter element of the first half-housing is manually cleaned.

The disadvantage of the described technical solution is the need for constant disassembly of the housing and manual cleaning of the filter element.

The technical problem solved by the utility model is the ability to clean the filter surface without dismantling the equipment and prolonged shutdown.

This problem is solved in that the combined self-cleaning separator contains a double cylindrical body, two removable covers, two filter elements, two water inlet pipes, in front of which a three-way separation valve is installed, and in the upper part of the body there is a common output manifold on which the outlet and air nozzles equipped with valves, removable covers have drain nozzles equipped with valves, and in each half-case there is a fixed coaxial fixed coax auger.

The design of the separator is shown in FIG. 1 and FIG. 2.

In FIG. 1 and FIG. 2, the following designations are adopted: 1 - half-shell, 2 - manifold, 3 - removable cover, 4 - inlet pipe, 5 - outlet pipe, 6 - air pipe, 7 - drain pipe, 8 - screw, 9 - filter element, 10 - three-way valve.

The separator combined self-cleaning works as follows. The liquid to be cleaned enters the three-way valve 10, which directs it to one of the inlet pipes 4 located in the half-shells 1, then the liquid is lowered along the screw 8, resulting in a swirling flow, in which heavy particles are pressed against the edges of the half-shell by centrifugal force and are lowered into the cover 3 to the drain pipe 7. Next, the liquid purified from heavy particles passes through the filter element 9, which traps the lighter particles, and is directed upward into the common collector 2, from which the output flows through the outlet pipe 5, air bubbles formed during the swirling of the flow are removed through the air pipe 6. If the first filtering element 9 becomes clogged by particles stuck in it, the cleaning mode starts and switches to the second half-housing 1: the three-way valve 10 redirects the flow of the liquid to be cleaned the second inlet pipe 4, the valve on the first drain pipe 7 opens, and the valve on the outlet pipe 5 closes. In the second half-shell, the liquid is cleaned of impurities similarly to the first, but in the outlet manifold 2 it forms a reverse flow in the first half-shell, cleans the first filtering element 9 of stuck particles, rinses the half-shell and removes sludge through an open drain pipe 7. After a few seconds, the cleaning mode stops , the valve at the outlet pipe opens, and the valve at the drain pipe closes, and normal operation of the separator resumes.

Two versions of the combined self-cleaning separator are possible. In the first version, manual actuators are installed on the three-way valve 10, the valve of the outlet pipe 5 and the valves of the drain pipes 7. In the second version, electric actuators are installed on the three-way valve 10, the valve of the outlet pipe 5 and the valves of the drain pipes 7, and an automatic air vent is installed on the air pipe 6.

Thus, the claimed technical solution allows you to clean the filter surface without dismantling the equipment and prolonged shutdown, and the absence of any moving elements directly inside the housing has a beneficial effect on the reliability of the separator.
