Abstract

Disclosed is a spiral drug mixer. A hollow rotating drum (6) is fixed on a central shaft (2), and the central shaft (2) is rotatablely installed on a fixing disk (10) and connected with a power head (11). The spiral drug mixer is characterized in that a spiral vane (4) is installed on the inner wall of the rotating drum (6), four sections of baffle sheets (3) are arranged on the periphery of the spiral vane (4) on the upper portion of the rotating drum (6), the lower portion of the rotating drum (6) is cone-shaped, and filtering nets (5) are distributed around the cone-shaped lower portion of the rotating drum (6). The spiral drug mixer is open and capable of continuously mixing materials and grading products.

Description

Screw type medicine batch mixer

[technical field]

The utility model relates to composition manufacturing, the processing of explosives equipment of explosive or thermit powder, refers to a kind of screw type medicine batch mixer especially.

[background technology]

In the production process of civil explosive; Need mix medicine, mostly traditional batch mixer is to carry out at closed environment, even if can carry out open batch mixing; The uniformity coefficient that mixes is also not ideal; The more important thing is that traditional batch mixer can not effectively separate certified products and defective work mostly, qualified and defective work all gets into next process.The tradition batch mixer can not be realized continuous feeding, in order to raise the efficiency, once need mix a large amount of materials, is difficult to like this mix, and does not also meet safety requirements.For combustible and explosive articles, mixed once is too many, and personnel and property all face very big potential safety hazard.

[summary of the invention]

To the shortcoming of prior art, the purpose of the utility model be to provide a kind of open type continuous batch mixing can be to the screw type medicine batch mixer of grading.

The utility model solves the technical scheme that its technical problem adopted: a kind of screw type medicine batch mixer is provided; The rotating cylinder of hollow is fixed on the central shaft, and central shaft is rotatably mounted on the ground fixed disk, and is connected with unit head; It is characterized in that: flight is housed along said rotating cylinder inwall; Rotating cylinder top is provided with four sections catch around flight, the rotating cylinder bottom is conical, is furnished with filter screen around this circular cone.

Unit head drives the rotating cylinder rotation through central shaft during work; Spice is put in rotating cylinder in the rotating cylinder port and is mixed, and the various materials that mix is directly fallen on the flight from top, and flight by the rotating cylinder band and filter screen not stall always is moving; These materials roll downwards along flight; Heavy obstruction through catch has mixed during to screen location, and the material less than filter opening exports through the entering fines of filter screen smoothly at last.In the middle of rotating cylinder, fall down the coarse fodder outlet and cover behind the cone-type spiral sheet greater than the material of filter opening, thereby with the spice classification.

The mesh of said filter screen can be prismatic, square or circular, perhaps other shapes.Filter screen is removable, changes filter screen and can adapt to varigrained particle article mixing.

As you know, in less space, can plant very long spiral curve.Make helix into flight, so, the confined space can be settled very long flight.On flight, place material and move, can greatly prolong mixing time, strengthened mixed effect along flight.If in the material moving process, add some points barrier again, effect is just desirable more.Mix almost this discharging, let them go out from some apertures, if what can go out is fines, so more sternward, the fines on the cone-type spiral sheet is just few more.In order to improve the fines rate, can on hole shape, try every possible means, some large granular materials can be better removed in the hole of having edges and corners.Loose not really, only go to tail along flight, get into the coarse fodder outlet.

The beneficial effect of the utility model is: opens wide and continuous batch mixing, and can be to grading.

[description of drawings]

Below in conjunction with accompanying drawing the utility model is done further to describe.

Fig. 1 is the outside drawing of the utility model.

Fig. 2 is the structural representation of the utility model.

Among the figure: 1 be last rotating cylinder, 2 for central shaft, 3 for catch, 4 for straight shape flight, 5 for filter screen, 6 for rotating cylinder, 7 for following rotating cylinder, 8 for the fines outlet, 9 for coarse fodder outlet, 10 be that fixed disk, 11 is a unit head.

[specific embodiment]

Referring to accompanying drawing, a kind of screw type medicine of the utility model batch mixer, the rotating cylinder 6 of hollow is fixed on the central shaft 2; Central shaft 2 is rotatably mounted on the ground fixed disk 10; And be connected with unit head 11, it is characterized in that: along said rotating cylinder 6 inwalls flight 4 is housed, rotating cylinder 6 tops are provided with four sections catch 3 around flight 4; Rotating cylinder 6 bottoms are conical, are furnished with filter screen 5 around this circular cone.

Unit head 11 drives rotating cylinder 6 rotations through central shaft 2 during work; Spice is put in rotating cylinder 6 in rotating cylinder 6 port and is mixed, and the various materials that mix is directly fallen on the flight 4 from top, and rotating cylinder 6 is being with flight 4 and filter screen 5 not stalls always moving; These materials roll downwards along flight 4; Heavy obstruction through catch 3 has mixed during to filter screen 5 positions, and the material less than filter opening exports 8 through the entering fines of filter screen 5 smoothly at last.In the middle of rotating cylinder 6, fall down coarse fodder outlet 9 and cover cone-type spiral sheet 4 backs greater than the material of filter opening, thereby with the spice classification.

In the embodiment of the utility model, the mesh of said filter screen 5 is prismatics.

In the embodiment of the utility model, said rotating cylinder 6 is by last rotating cylinder 1, rotating cylinder 7 and conical bottom three parts are formed down.

Claims

1. screw type medicine batch mixer; The rotating cylinder of hollow (6) is fixed on the central shaft (2), and central shaft (2) is rotatably mounted on the ground fixed disk (10), and is connected with unit head (11); It is characterized in that: flight (4) is housed along said rotating cylinder (6) inwall; Rotating cylinder (6) top is provided with four sections catch (3) all around in flight (4), and rotating cylinder (6) bottom is conical, is furnished with filter screen (5) around this circular cone.
