Description

The invention relates to mechanical engineering and can be used to purify and disinfect water.

Closest to the proposed device design is a filter for cleaning fuel [1]. It includes a housing equipped with a cover, a filter element, an inlet fitting located in the cover along the axis of the housing, an outlet pipe and a settler having the shape of a funnel facing downward with a narrow part. The lid is removable in the form of a plate facing upside down. An electromagnet in the form of a truncated cone expanding upward is installed along the walls of the sump. The inlet fitting is connected to a tube mounted along the axis of the housing. At the end of the tube below the filter element in a horizontal plane there is a distributor made in the form of tubes bent in the form of semicircles, the tubes being installed symmetrically with respect to the axis of the housing. The outlet pipe is mounted tangentially to the housing in the lid in the direction of bending of the tubes relative to the axis of the housing. The sump is equipped with a plug for the discharge of impurities installed in its lower part.

The disadvantage of this device is: low quality cleaning and the inability to use for disinfection of water.

The purpose of the invention is to improve the quality of cleaning and providing the possibility of disinfection of water.

The goal is achieved by the fact that a cylindrical glass with holes is installed in the housing, which are made in its bottom along the circumference along the generatrices. A ring is installed in the upper part of the body, the outer surface of which is in contact with the inner surface of the body, and the inner surface of the ring is in contact with the outer surface of the cylindrical cup. The filter element is made in the form of a cylinder with a hole along the axis of the cylinder and is installed inside a cylindrical glass. An ultraviolet lamp is installed inside the filter element along its axis. The inlet fitting is connected to a tube curved in the form of a spiral, and placed in an annular gap between the inner surface of the housing and the outer surface of the cylindrical glass. The tube is equipped with nozzles installed at an acute angle to it in the direction of spiral winding.

Figure 1 shows a device for cleaning and disinfecting water, figure 2 is the same, a section along aa.

A device for cleaning and disinfecting water comprises a housing 1 provided with a lid 2 made removable in the form of a plate facing upside down, a filter element 3, an inlet fitting 4, an outlet pipe 5 installed in the lid 2, and a sump 6 having the shape of a funnel facing down a narrow part, equipped with a plug 7 for the discharge of contaminants installed in its lower part. A cylindrical cup 8 is installed in the housing 1 with holes made in its bottom along the circumference along the generatrices. A ring 9 is installed in the upper part of the housing, the outer surface of which contacts the inner surface of the housing 1, and the inner surface of the ring 9 contacts the outer surface of the cylindrical cup 8. The filter element 3 is made in the form of a cylinder with a hole along the axis of the cylinder and is installed inside the cylindrical cup 1. Inside the filter element 3, an ultraviolet lamp 10 is installed along its axis. The inlet fitting 4 is connected to a tube 11 curved in the form of a spiral placed in an annular gap between the inner erhnostyu body 1 and the outer surface of the cylindrical sleeve 8. The tube 11 is provided with nozzles 12 mounted at an acute angle thereto in the direction of spiral winding.

The device operates as follows.

Water through the inlet 4 enters the tube 11 and through the pipes 12 installed at an acute angle to it enters the space between the inner surface of the housing 1 and the outer surface of the cylindrical glass 8, where it is involved in rotational motion. When water rotates in the annular gap between the inner surface of the housing 1 and the outer surface of the cylindrical cup 8, the particles of dirt in the liquid are discarded under the action of centrifugal force to the inner surface of the housing 1 and then fall into the sump 6. Here, the water changes direction, loses speed and passes through filter element 3, where it is further cleaned. Then the water falls into the gap between the filter element 3 and the ultraviolet lamp 10, where it is disinfected by ultraviolet rays. After that, the water is removed to the outside through the outlet pipe 5 installed in the cover 2. The impurities present in the water accumulate in the sump 6 and in the filter element 3. Periodically, the filter element 3 is replaced, and the dirt from the sump 6 is removed through the plug 7 installed in the lower part of the sump 6.

The presence of an annular gap, a tube curved in the form of a spiral, with nozzles installed at an acute angle to it in the direction of winding the spiral, as well as a sump, imparts rotational motion to a thin layer of water, followed by a sharp decrease in its speed and a change in the direction of its movement. This ensures high-quality separation of large contaminants from the water, finer particles are captured by the filter element.

The presence of an ultraviolet lamp mounted along the axis of the filter element allows you to disinfect water.

The above features of the device allow you to clean and disinfect water efficiently.
