RU219524U1 - SLUDGE TANK WITH REPLACEABLE CONTAINER FOR HYDROCYCLONE - Google Patents

Abstract

The utility model relates to the field of mine water neutralization and can be used to release treated wastewater into natural water bodies using hydrocyclones. It consists of a sludge collector with a replaceable container for accumulation of the sludge-liquid mixture coming from the hydrocyclone; moreover, this container is equipped with handles, with the help of which, as the sludge-liquid mixture accumulates, it is removed from the sludge collector body. The body of the sludge collector is closed with a threaded lid and with an inlet for supplying the sludge-liquid mixture from the hydrocyclone.

Description

The utility model relates to the field of mine water neutralization and can be used to release treated wastewater into natural water bodies using hydrocyclones.

A well-known hydrocyclone containing a cylindrical-conical body, a pipe for supplying the initial suspension and pipes for removing clarified and thickened fractions of the suspension, characterized in that it is equipped with a device for removing the thickened fraction of the suspension, made in the form of two horizontal disks installed coaxially with the body of the hydrocyclone, the lower of which is fixed on shaft and has the ability to rotate and vertically move, and the top has the shape of a ring, the inner diameter of which is equal to the diameter of the pipe for removing the thickened fraction of the suspension and is rigidly connected to the body of the hydrocyclone, forming a radial channel, and including a container for the thickened fraction of the suspension, rigidly connected to the upper disk and forming with it a cylindrical chamber with nozzles for removing the thickened fraction of the suspension [1].

Known open hydrocyclone for wastewater treatment from suspended particles, containing a cylindrical body with a conical bottom and nozzles for supplying and discharging liquid, an inner cylinder, in the upper part of which an oil-retaining shield and a conical diaphragm are mounted, and in its lower part a conical reflector is fixed, characterized in that that it is equipped with a shell enclosing the cylindrical body, in which the steam heat exchanger is rigidly fixed, and a mechanical scraper with a rotation drive mounted above the oil-retaining shield to remove the ascending pulp flow, and a gravity sludge removal mechanism is mounted in the lower part of the conical bottom.

The closest device according to the implemented technology is a hydrocyclone containing a housing, an associated upper shell and a lower conical shell, a tangential inlet for supplying the initial product, a drain pipe for withdrawing a clarified product, equipped with a filter element with a filtering side surface, and a sand pipe for withdrawing a heavy product.

The disadvantage of this device is that the hydrocyclones have a rather complex configuration and high energy costs.

The objective of the proposed sludge collector with a replaceable container for the hydrocyclone is to simplify the design of the hydrocyclone and reduce energy costs for the removal of accumulated sludge.

This problem is solved by using a sludge collector with a replaceable container for the accumulation of a sludge-liquid mixture. The design of the device is shown in figure 1.

The sludge collector with a replaceable container for the hydrocyclone includes a cylindrical metal body (1), the volume of which is approximately equal to the volume of the sludge collector permanently attached to the hydrocyclone. From above, this body is closed with a cap (2) with a thread; a container (3) made of thin sheet material is installed inside the body (1). The container is equipped with two handles (4) for removing from the tank. The cover has an opening (5) for the inlet of the slurry-liquid mixture.

The supply of the slurry-liquid mixture is blocked (by a clamp or valve), a flexible tube is diverted from the filling hole (5). The cover (2) is unscrewed, and the container (3) filled with the sludge-liquid mixture is removed from the body (1) using the handles (4). Instead of the filled container (3), a previously prepared clean container is inserted. The cover (2) is screwed to the body (1), a flexible tube is connected to the filler hole (5) and the clamp is removed or the valve is opened. The sludge-liquid mixture is removed from the filled container. If it is not possible to completely remove the sludge-liquid mixture, then before installing it in the sludge collector, the container is washed with a small amount of water, after which it is also ready for use.

Thus, the implementation of the proposed device provides the technical result: saving energy resources, simplifying the cleaning of the sludge trap, as well as simplifying the design of the sludge trap with a replaceable container for the hydrocyclone. The resulting sludge is stored and disposed of as it accumulates (for example, it is used for sprinkling roads during icing).
