Description

The device relates to techniques for cleaning recycled process water and can be used on horizontal sumps.

A device for dumping industrial wastewater from sedimentation tanks, including a floating water intake in the form of a tray with a flexible hose, connected to the outlet. To increase the efficiency of use by preventing the ingress of suspended matter into the discharged water, the tray is made with a sloping bottom, overflow windows and a drainage tank, and is also equipped with a turning mechanism and is located along the radius of the sump. (A.S. No. 929153. Class B01D 21/24.).

The disadvantages of the known device, is the clogging of the spillway windows floating on the surface with wood chips and other debris, as well as a significant consumption of electricity needed to rotate the tray. This leads to a decrease in the efficiency of the device.

The closest technical solution for the totality of features is a device for discharging industrial wastewater from the sump, containing a floating water receiver located in the body of the sump in the form of a tray with an inclined bottom and drainage windows, connected to the pipe and mounted to rotate around the water outlet pipe. In order to increase the efficiency of the device, the water outlet pipe is made in the form of two vertical coaxially arranged pipes, the outer one of which is made corrugated and hermetically fixed with the lower part on the inner pipe and the upper one on the tray, while the device is equipped with vertical plates mounted at diametrically located ends tray parallel to its axis, and the tray is made with a Central hole for the release of wood chips, located below the level of the drain windows. (A.S. No. 1717171 class B01D 21/24.).

A disadvantage of the known device in the complexity of the structure made of metal, due to which corrosion of the inner surface of the outlet pipe and corrugated pipe can occur.

The main objective of the utility model is to increase the efficiency of the device.

To achieve this goal, a device for cleaning industrial wastewater from a sump, containing a floating water receiver and a spillway device located in the tank of the sump, according to the technical solution, the floating water receiver is mounted on pontoons, with a squeezing roller and drums fixed on them, on which hygroscopic material is stretched, in the form endless tape, and the spillway device is made in the form of a gutter located along the entire width of the endless tape, under the squeeze roller and one of the drums.

In relation to the prototype, the proposed device has the following distinctive features: a floating water intake is mounted on pontoons, with a squeezing roller and drums fixed on them, on which hygroscopic material is stretched, in the form of an endless belt, and the spillway device is made in the form of a gutter located along the entire width endless tape, under the squeeze roller and one of the drums.

The presence of the pontoon ensures the stability of the structure on the water surface of the sump compared with the floats in the prototype.

The hygroscopic material made of geotextile, for example, zeolite fiber in the form of an endless tape, allows you to evenly adsorb fine particles on your surface.

The gutter located across the entire width of the hygroscopic endless belt under the squeeze roller and one of the drums provides the most complete collection of purified water.

The essence of the device is illustrated by graphic materials, which depict:

Figure 1 presents a General view of a utility model;

Figure 2 presents a top view.

The device located in the sump 1 consists of two pontoons 2, propulsion 3, squeezing roller 4, as well as the leading 5 and driven drums 6, on which hygroscopic material is tensioned, made in the form of an endless tape 7 and a spillway made in the form of a groove 8, located on the entire width of the hygroscopic endless tape, under the squeeze roller 4 and the drive drum 5.

A device for cleaning industrial wastewater from the sump works as follows:

Contaminated wastewater, saturated with suspended particles, enter the sump 1. The surface layer of water is absorbed by the immersed portion of the geotextile material made in the form of an endless tape 7. The device provides a surface water intake by capillary effect of the material made in the form of an endless tape. Finely dispersed soil particles of industrial stocks are adsorbed by the material at the moment of absorption, as a result of which water is purified. The smaller the diameter of the capillary channels, the more efficient the operation of the device in terms of the quality of the process water from fine particles. Using the propulsion device 3, as well as the entire structure mounted on the pontoons 2, the driving drum 5 rotates, which in turn drives the hygroscopic material, made in the form of an endless tape 7, and the driven drum 6 counterclockwise. A portion of the hygroscopic material 7 that has absorbed clarified water of the surface layer is scrolled and passes over the surface to the squeezing roller 4. In the place where the material 7 passes between the squeezing roller 4 and the driving drum 5, the material 7 is squeezed. The purified water flows into the spillway device, made in the form of a gutter 8 and is discharged outside the sump 1.

The technical result of the claimed device is as follows:

1. Improving the contact of the working body with the environment;

2. Effectively preventing mechanical impurities from entering drains;

3. Water purification from chemical elements by adsorption of the latter on a geotextile material (zeolite fibers can be used as a material).
