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 the low quality of 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 the inner surface of the body is mirrored. A hollow cylinder is installed in the housing, the outer surface of which is mirrored. 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 hollow cylinder. Inside the hollow cylinder, a removable filter element is installed. The lower edge of the hollow cylinder is provided with stops facing inside it. 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 hollow cylinder. The tube is equipped with nozzles installed at an acute angle to it in the direction of spiral winding. Ultraviolet LEDs are installed on the inner surface of the housing.

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. The inner surface of the housing 1 is made mirrored. In the housing 1, a hollow cylinder 8 is installed, the outer surface of which is made mirrored. 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 hollow cylinder 8. A filter element 3 is installed inside the hollow cylinder, which is removable. The lower edge of the hollow cylinder is provided with stops 10 directed inside it, which are designed to fix the filter element 3. The inlet fitting 4 is connected to a tube 11 curved in the form of a spiral placed in the annular gap between the inner surface of the housing 1 and the outer surface of the hollow cylinder 8. Tube 11 equipped with nozzles 12 mounted at an acute angle to it in the direction of winding the spiral. Ultraviolet LEDs 13 are installed on the inner surface of the housing.

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 hollow cylinder 8, where it is involved in rotational motion. Under the action of 13 ultraviolet rays emitted by the LEDs, which are repeatedly reflected from the internal surface of the housing 1 and the external surface of the hollow cylinder 8, the water is disinfected and then enters the internal cavity of the sump 6. When the water rotates in the annular gap between the internal surface of the housing 1 and the external surface of the hollow cylinder 8, the particles of contaminants in the liquid are discarded under the action of centrifugal force to the inner surface of the housing 1 and, further, fall into the sump 6. Referring water changes direction of movement, loses speed and passes through the filter element 3, which is further purified. Then 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 a plug 7 installed in the lower part of the sump 6 .

The presence of a hollow cylinder, a ring and a tube curved in the form of a spiral inside the body, with nozzles installed at an acute angle to it in the direction of spiral winding, allows water to be distributed in a thin layer in the annular gap between the internal surface of the body and the external surface of the hollow cylinder, which allows high-quality to disinfect it with the help of ultraviolet rays repeatedly reflected from mirror surfaces emitted by LEDs mounted on the inner surface of the housing.

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 above features of the device allow high-quality purification of water.
