RU2625958C2 - Device for cleaning water bodies from algae - Google Patents

Abstract

FIELD: transportation.

SUBSTANCE: device contains a watercraft with an appliance for taking water with algae, which feeds the mixture to pairwise counter-rotating drums with a rubberized surface installed on each side. The drums are located at an angle to the surface of the water body with the possibility of changing the position of one drum relative to the other, forming a gap between them, transferring from the transport position to the working position, and also with the possibility of making a battery of a series of pairwise counter-rotating drums.

EFFECT: simplification of the technological process of cleaning the water body from algae and reducing the energy intensity of its implementation.

Description

The invention relates to agricultural machinery, in particular to the creation of devices for cleaning water bodies from algae.

Known biological methods for cleaning water bodies from algae by introducing biological products into the water column, as well as mechanical means, by taking water with algae into the water intake. In this case, their biological ability to precipitate is used when they are cooled.

The use of biological products for cleaning water bodies from algae is an expensive process and requires special conditions for their use. In the summer, the water should warm up to a certain temperature. In this case, the dosage of the active substance should be in strictly recommended doses, otherwise the effectiveness of the use of biological products is reduced.

Known devices for cleaning water bodies from algae, the technological process of which provides for cooling a mixture of water with algae, structurally complex, energy-intensive and overall. By the totality of common essential features, the method for cleaning water bodies from algae and the device for its implementation RU No. 2068053 C1 is taken as a prototype.

The disadvantages of the known devices.

1. Cleaning water bodies from algae by biological means using biological products is an expensive process.

2. The technological process of cleaning water bodies from algae by mechanical means is multi-operational and energy-intensive.

3. The design of water purification devices from algae is complex and overall.

The objective of the invention is to simplify the process of cleaning a reservoir of algae and reduce the energy intensity of its implementation.

The task is performed by destroying the integrity of the body of algae by mechanical means, after which the algae die off and precipitate.

Moreover, the device for their destruction is made in the form of pairwise meeting drums with a rubberized surface, located at an angle to the surface of the reservoir, with the possibility of changing the position of one drum relative to another with the formation of a gap between them, as well as the possibility of compiling a battery of pairwise meeting drums.

EFFECT: technological process of cleaning a water body from algae is simplified, and its energy consumption is reduced.

The technical result is achieved through the use of a method of purification of a reservoir of algae by destroying the integrity of the organism of algae using mechanical means. In this case, a device made in the form of pairwise meeting drums is used.

Algae, along with water, falling into the space between the drums, are destroyed (crushed), then die off and precipitate. At the same time, when performing the technological process, there is no need to use expensive biological products, to provide additional devices in the device design for performing the technological process and their drive mechanisms. This allows us to simplify the design of the device, the technological process of cleaning the reservoir of algae and reduce the energy intensity of its implementation.

The noted positive aspects of the declared object will allow to obtain an economic effect and wide practical application.

The drawing schematically shows a device for cleaning water from algae.

The device comprises a watercraft 1, on each side of which counter-rotating drums 2 are installed in pairs with a device 3 for water intake with algae, inside which a grate 4 is fixed to protect against large bodies. The translation of the working bodies from the transport position to the working one and vice versa is provided by mechanism 5.

The device operates as follows.

Before starting the technological process of cleaning water bodies from algae, the necessary gap between drums 2 is established. Its optimal value depends on the biological type of algae and the phase of their development. When the vehicle 1 moves, the algae with water with the device 3 for collecting the mixture are fed to counter-rotating drums, where the algae under the influence of pressure forces of the drums are destroyed (crushed) and dumped into the water column. In this case, the algae die off and precipitate at the bottom of the reservoir. The protection of the drums from the ingress of large foreign bodies is provided by the grill 4.

Counter-rotating drums 2, installed at an angle to the surface of the reservoir, reduce the resistance to their movement of water and improve the process of the descent of the destroyed algae from the surface of the drums.
