RU218467U1 - Chemical wastewater decontaminator - Google Patents

Abstract

The utility model relates to the field of chemical (reagent) disinfection of liquid waste (drainage) contaminated with pathogenic biological agents of III-IV pathogenicity groups.

The body of the unit is made as a single piece of parts cut from a sheet, with a removable cover and a level gauge. In this case, the stirrer is fixed on the lid from the outside by a handle, and from the inside - by a blade. All seams are soldered with polypropylene rod. The lid itself sits on a contour of rails soldered to the inner walls and is fixed with bolts. The entrance and exit are located on the same wall, where the top is the entrance, and the bottom is the exit.

EFFECT: simplification of the design, simplification of installation, faster and more complete dissolution of the reagent and ensuring the operability of the level gauge during long-term operation.

Description

The utility model relates to the field of chemical (reagent) disinfection of liquid waste (drainage) contaminated with pathogenic biological agents of III-IV pathogenicity groups.

From the conducted patent and information search, the closest technical solution is a plant for chemical disinfection of liquid waste (effluents) in PRC laboratories and hospital departments (RU 205482 U1), which is a rectangular plastic container with a built-in inlet and outlet, mounted on adjustable supports and having a removable cover, a float sensor of the liquid level. The lid has a hole with a lid for loading disinfectants. A manual solution mixing system is mounted on the container lid, consisting of a rod with two blades and a handle. On the front side of the container there are latches for closing the lid.

The disadvantages of the known design is the complexity of manufacturing and use, as well as lower performance.

The task to be solved by the claimed utility model is to simplify the assembly, installation and use of the installation, as well as to ensure a longer service life.

The problem is solved in the installation for decontamination of wastewater, the body of which is made of a single product from parts cut from a sheet, with a removable cover and a level gauge. In this case, the stirrer is fixed on the lid from the outside with a handle, and with an inner blade. All seams are soldered with polypropylene rod. The lid itself sits on a contour of rails soldered to the inner walls and is fixed with bolts. The entrance and exit are located on the same wall, where the top is the entrance, and the bottom is the exit.

The technical result of using the utility model is to simplify the design by reducing the number of parts and the absence of the need to install additional elements, since the design of the device supports is made as a continuation of the side walls. The input and output are on the same side of the device, which allows you to place it closer to the wall. The single plate agitator is located close to the bottom, which will allow, with little effort on the lever, to create a significant flow of liquid at the bottom of the tank to ensure faster and more complete dissolution of chemicals added in solid form. The hollow level gauge used is an inverted tube, closed at the top, which makes it possible to guarantee the draining of the level gauge when draining the treated liquid from the tank and to guarantee the performance of the level gauge during long-term operation.

Brief description of drawings:

In FIG. 1 shows a top view of the plant, FIG. 2 is a front view, in Fig. 3 is a side view, in Fig. 4 - 3D model.

Numerical designations in the drawings:

1) Stirrer;

2) Level gauge;

3) Revision;

4) Entrance of drains;

5) Effluent outlet.

The utility model works as follows. Infected wastewater enters the input 4 of the device until the level gauge 2 is raised. Reagent in the form of tablets is poured into revision 3. The agitator 1 is then driven by the handle until decontamination is complete. After that, the disinfected effluents are drained into the sewer through outlet 5 when the check valve handle is turned.

Claims (2)

1. A device for the decontamination of wastewater, the body of which is equipped with a level gauge and a removable cover with a stirrer fixed on the cover, the inlet and outlet are located on the same wall, where the upper one is the inlet and the lower one is the outlet, characterized in that the body is made of a single piece of parts cut from a sheet in which all seams are soldered with a polypropylene rod, and the lid is planted on a contour of rails soldered to the inner walls and fixed with bolts. 2. Installation according to claim 1, characterized in that the stirrer is fixed on the lid from the outside with a handle, and with the inside - with a blade.
