Abstract

The utility model discloses a spiral pipe-type liquid-liquid mixer which comprises an agitating barrel (1). The utility model is characterized in that the agitating barrel (1) is provided with an inlet support (2) and an outlet support (2') which are arranged on the two sides of the agitating barrel (1) and connected by a main shaft (3), wherein the main shaft (3) is provided with spiral guide vanes (4) and coincides with the central axis of the agitating barrel (1), the spiral guide vanes (4) are tangent with the inner wall of the agitating barrel (1). The utility model realizes completely homogeneous mixing between liquids, does not arouse liquid blocking and can prevent the short-flow phenomenon. Simultaneously, the utility model is easy to produce and convenient to disassemble and maintain.

Description

Spiral Duct Type Liquid-liquid Mixer

Technical field

The utility model belongs to a kind of mixed stirring device, specifically, is a kind of Spiral Duct Type Liquid-liquid Mixer.

Background technology

Traditional liquid liquid mixing stirring technique, often the mixing of two media is placed in the special-purpose stirring drum and is stirred, or rolled, realize mixing stirring drum, its shortcoming is: this hybrid mode is more spacious, is difficult to realize fully evenly mixing between liquid.

Also have and adopt scissor pipe-line mixer, promptly at the fixing some flow deflectors of the inwall that stirs drum, all flow deflectors are angle with the main shaft that stirs drum, being the dentation dislocation between the flow deflector arranges, its shortcoming is: when suspension concentration is higher, this pipe-line mixer stops up, causes short stream easily, and the bad processing of blender, bad dismounting, maintenance.

The utility model content

The purpose of this utility model provides a kind of Spiral Duct Type Liquid-liquid Mixer, can realize fully evenly mixing between liquid, and the liquid obstruction can not take place.

For achieving the above object, a kind of Spiral Duct Type Liquid-liquid Mixer described in the utility model includes the stirring drum, and its key is: input port support and delivery outlet support are installed in described stirring drum; Described input port support and delivery outlet support are arranged on the two ends of stirring drum, and the two connects by main shaft, and the spirality guide vane is installed on the described main shaft.

The spirality guide vane can be realized the Forced Mixing of multiple fluid medium, the fluid passage that this spirality guide vane coordinates in stirring drum, its resistance is little, mix, simultaneously, the design of spirality guide vane is installed on main shaft, can be according to mixing the length that requires to prolong or reduce helical blade.

Described main shaft overlaps with the axis of described stirring drum, and is gapped between the inwall of the outer of described guide vane and described stirring drum.

Described delivery outlet support is welded on the described stirring drum, and the center of this delivery outlet support relies on the bolting residence to state an end of main shaft, and the other end of this main shaft is welded with described input port support, the inwall matched in clearance of this input port support and described stirring drum.

Only rely on bolt just can realize the installation of main shaft and guide vane and change, make the processing of product easier, be convenient to the dismounting and the maintenance of whole device.

Two external end heads at described stirring drum are respectively arranged with sealing flange, are convenient to be connected with outside input, output pipe.

Remarkable result of the present utility model is: can realize the fully evenly mixing between liquid, and the liquid obstruction can not take place that can avoid the generation of short flow phenomenon, simultaneously, the utility model processing is easy, is convenient to dismounting and maintenance.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cross section view of Fig. 1;

Fig. 3 is a structure right view of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As Fig. 1, Fig. 2, shown in Figure 3: a kind of Spiral Duct Type Liquid-liquid Mixer includes and stirs drum 1, wherein: input port support 2 and delivery outlet support 2 ' are installed in described stirring drum 1; Described input port support 2 and delivery outlet support 2 ' are arranged on the two ends of stirring drum 1, and the two connects by main shaft 3, on the described main shaft 3 spirality guide vane 4 is installed.

Spirality guide vane 4 can be realized the Forced Mixing of multiple fluid medium, the fluid passage that this spirality guide vane 4 coordinates in stirring drum 1, its resistance is little, mix, simultaneously, 4 designs of spirality guide vane are installed on main shaft 3, can be according to mixing the length that requires to prolong or reduce guide vane 4.

Described main shaft 3 overlaps with the axis of described stirring drum 1, and is gapped between the inwall of the outer of described guide vane 4 and described stirring drum 1.

As shown in Figure 3: described delivery outlet support 2 ' is welded on the described stirring drum 1, the center of this delivery outlet support 2 ' relies on the bolting residence to state an end of main shaft 3, the other end of this main shaft 3 is welded with described input port support 2, the inwall matched in clearance of this input port support 2 and described stirring drum 1.

Only rely on bolt just can realize the installation of main shaft 3 and guide vane 4 and change, make the processing of product easier, be convenient to the dismounting and the maintenance of whole device.

The equipment requirement on machining accuracy is not high, and guide vane 4 need not be considered machine tooling.Adopt oxygen welding and common electric welding just can meet the demands, and guide vane 4 materials can adopt unlike material according to different fluid media (medium) types.

Two external end heads at described stirring drum 1 are respectively arranged with sealing flange 5, and 5 ', be convenient to stir drum 1 and be connected with input, the output pipe of outside, guarantee the sealing property of equipment.

Working condition is as follows:

As shown in Figure 1: rely on external force, different liquids is injected stirring drum 1 simultaneously, and through the spiral channel that spiral stream guidance blade 4 forms in stirring drum 1, fluid rotates along guide vane 4 direction of rotation, make the interior different fluid of pipeline form strong turbulent flow, mix mutually.
