Abstract

The utility model discloses a powdered medicine feeding device used in the field of environment-friendly water treatment. A powder and water mixing system of the powdered medicine feeding device mainly comprises a rotational flow tube (4), a jet flow tube (2), a powder supply machine (5), a three-chamber medicine melting box (6), a water inlet pipe assembly (3) and the like. The utility model effectively avoids the phenomena of conglobation and agglomeration of powdered medicine, and greatly improves the efficiency and quality of melting medicine.

Description

A kind of powder dosing device

Technical field

The utility model relates in a kind of environmental protection water treatment administration system, the dissolving dosing and the throwing device of the former medicine of dry powder.

Background technology

At present, the problem that existing powder medicine machine exists: ideal powder water mixes molten in bulk putting owing to do not have comparatively, dry powder forms caking easily or reunites in molten medicine-chest, be difficult to obtain the even soup of ideal concentration, caking or reunion simultaneously very easily stopped up and added pipeline, causes unnecessary loss for production and maintenance.

The utility model content

The purpose of this utility model is will be by a kind of novel powder dosing device of design, possess mainly and to form the doline moisture film of rotation and porous by whirl cylinder, conical hopper, jet tube, water inlet pipe assembly etc. and spray dual function and can make medicinal powder disperse to moisten molten mixing to dissolve fast, it can effectively overcome the existing molten medicine of type easily caking or reunion, very easily stops up shortcomings such as adding pipeline.

The utility model is achieved in that a kind of powder dosing device of design, mainly is made up of stirrer, jet tube, water inlet pipe, whirl cylinder, confession powder machine, the molten medicine-chest in three chambeies, spout hole, conical hopper; It is characterized in that: the powder water mixing system of this machine is to be become by the jet tube, whirl cylinder, the powder supplying mechanism that are installed on the molten medicine-chest in three chambeies; Its jet tube inner tube wall evenly is drilled with the spout hole of some amount along the circumference of a uniform section, and spout hole penetrates water (flow) direction and points to the whirl cylinder center; Water inlet pipe and whirl cylinder cylinder inboard wall are tangent, and the whirl cylinder center is provided with conical hopper; Supply medicine from whirl cylinder top for the powder machine.

Description of drawings

Fig. 1 is the front view of the utility model powder dosing device, also is summary figure.

Fig. 2 is the assembling front view of the utility model powder dosing device whirl cylinder and jet tube.

Embodiment

Describe detail and the working condition that the utility model proposes in detail below in conjunction with Figure of description.

The working condition of the utility model powder dosing device is such: shown in Figure 1, during the work of beginning preparating liquid, valve open on the dilution water pipeline, the dilution water of certain pressure enters whirl cylinder 4 respectively by water inlet pipe group 3 and jet tube 2 forms eddy flow moisture film and ring jetting curtain, start working for powder machine 5 then, supply medicine by medicine, the water proportional set, medicinal powder drops on dispersion and molten with the water profit rapidly on the eddy flow moisture film, and the powder water that flows down is subjected to encircling the injection mixing of jetting curtain again through the jet tube 2 of bottom.After the dual function of eddy flow moisture film and ring jetting curtain, the powder medicine that enters molten medicine-chest 6 is disperseed preferably and is moistened molten mixing, is easy under the effect of molten medicine-chest stirrer 1, reaches the molten pharmacy liquid of ideal.

Whirl cylinder 4 and jet tube 2 are as shown in Figure 2, the water inlet pipe and the cylinder inboard wall of whirl cylinder 4 its bottoms are tangent, water inlet utilizes tangent principle to form eddy flow, and eddy flow is waterborne to be raised to that the conical hopper 8 from the center flows down behind the certain altitude, thereby forms the doline moisture films of rotation on conical hopper 8 surfaces; Jet tube 2, its water cavity is a cylinder, on one or more cross sections of cylinder certain altitude, on a circumference, bore the equally distributed spout hole 7 of some amount along inwall, water in the water cavity penetrates from spout hole 7 with certain pressure, thereby form the jet cascade that points to the center together, the powder water that top is flowed down is subjected to spraying again and mixes.Whirl cylinder 4 and jet tube 2 are bound up up and down, make eddy flow moisture film and ring Zhou Duokong injection stream cascade moisten molten mixing effect to the dual dispersion of medicinal powder and finish continuously, effectively raise the molten medicine quality and the efficient of chemicals dosing plant.

Claims (1)

1, the utility model is a kind of powder dosing device, mainly is made up of stirrer (1), jet tube (2), water inlet pipe (3), whirl cylinder (4), confession powder machine (5), the molten medicine-chests in three chambeies (6), spout hole (7), conical hopper (8); It is characterized in that: the powder water mixing system of this machine is to be made of the jet tube (2), whirl cylinder (4), the confession powder machine (5) that are installed on the molten medicine-chests in three chambeies (6); Its jet tube (2) inner tube wall evenly is drilled with the spout hole (7) of some amount along the circumference of a uniform section, and spout hole (7) penetrates water (flow) direction and points to whirl cylinder (4) center; Water inlet pipe (3) is tangent with whirl cylinder (4) cylinder inboard wall, and whirl cylinder (4) center is provided with conical hopper (8); Supply medicine from whirl cylinder (2) top for powder machine (5).
