SU1556732A1 - Mixer-batcher for liquids and gases and method of production thereof - Google Patents

Abstract

The invention relates to hydrometallurgy, can be used in the process of pulp preparation. It provides a simplified design and proportional dosing of the component into the moving medium. The mixer - dispenser for liquids and gases contains a pipeline in which a rubber hose is installed, one end of which is fixed and through it flows the component mixed into the main medium flow, and the other is plugged and equipped with a swirling device with blades. The latter, depending on the flow rate, twist the hose relative to the longitudinal axis, which leads to a change in the cross-sectional area of the holes in the hose. The method of manufacturing the mixer - dispenser includes the operation of making holes in the hose. For this, one end of the hose is fastened and the other end is twisted around a longitudinal axis, after which holes are made. 2 sec. f-ly, 2 ill.

Description

The invention relates to hydrometallurgy and can be used in any field of national economy where automated dosing is necessary when mixing additives in moving current media.

The purpose of the invention is to simplify the design and expand the technological capabilities of the device due to proportional dispensing of the components.

FIG. 1 shows schematically a mixer-dosing unit, a section; in fig. 2 - changing the shape of the hole in the hose.

The device comprises a pipeline 1, in which a perforated hose 2 is installed, made of an elastic material. The free end 3 of the hose in the pipeline is plugged and provided with blades 4, which are a twisting device. The effective area of the holes 5 in the hose may vary (Fig. 2). The hose is connected to the source 6 supply of one of the components.

A method of manufacturing the proposed mixer includes the operation of perforating a hose. For this, one end, through which the components are fed, is fixed, and the other, muffled, is twisted around the longitudinal axis, after which the perforation is carried out, for example, with round holes. After the holes have been drilled, the hose is brought back to its original position and the effective cross-sectional area of the holes is reduced, since the perforation of the hose material was carried out in the elastic-deformed state.

The device works as follows.

With a steady-state set flow mode in the main flow pipe 1, the latter flows around the blades 4 of the swirling device and twists the hose, changing the shape and cross-sectional area of the metering holes 5 to the average value between the minimum and maximum possible (flat slot and circle B in Fig. 2) ), opening the slit-like (in the initial state) metering orifices until the total area of the orifices necessary for the passage of a given amount of the substance to be metered into the main stream is reached.

With an increase in the speed of movement (opening holes and / or the value of overpressure in the supply system, and / or diameter of the metering holes. It is possible to create conditions for proportional dosing at any flow rates, flow rate differences, and other variable factors. .
