Abstract

The utility model discloses a mixer with a coaxial double-stirrer device, which mainly consists of a motor, a speed reducer, a barrel cover, a barrel body, stirrers, a rotating arm, a framework, a hydraulic cylinder system and the like. The speed reducer is fixed on a supporting plate on the barrel cover, the motor is arranged on the speed reducer, a round head is arranged under the supporting plate, the rotating arm is fixed on the round head, the stirrers are fixed on a rotating joint, a rotating flange is arranged between the rotating joint and the round head, the motor, the speed reducer, the barrel cover, a revolution shaft, the barrel body and an autorotation shaft are connected in series integrally from top to bottom so as to be connected with the framework, the rotating shaft is the revolution shaft and rotates circumferentially along the barrel wall when in revolution, and the stirrers are double-spiral bands, rotate in a direction opposite to that of the rotating arm when in autorotation and have rotation speed higher than the revolution speed. Since the speeds of the stirrers and the rotating arm are different, mixing speed and efficiency of the mixer are higher, and sufficient mixing can be completed within 1-4min.

Summary of the invention

In order to solve deficiency of the prior art, the utility model provides a kind of coaxial double stirrer device mixer, solves existing mixer mixing speed degree, problem such as inhomogeneous,

The purpose of this utility model realizes by the following technical solutions:

A kind of coaxial double stirrer device mixer, mainly partly form by motor, reductor, bung, staving, agitator, pivoted arm, frame and cylinder device etc., be fixed with reductor on the gripper shoe on bung top, the top of reductor is motor, round end is arranged on the below of gripper shoe, pivoted arm is fixed on the round end, agitator is fixed on the swivel joint, be provided with rotary flange between swivel joint and round end, motor, reductor, bung, hollow shaft, staving and the axis of rotation order series connection up and down link to each other with frame for one.

Described pivoted arm and agitator, pivoted arm is connected with round end, be hollow shaft, during its revolution, make circular motion along the bucket wall, to separate with the bucket wall attached to the material on the bucket wall, agitator is connected with swivel joint, is the double helix band, its time rotational, the direction of rotating with pivoted arm is opposite, speed is higher than revolution speed, and under the effect of two kinds of speed, material forms powerful eddy current and convection current in the bucket, make between the full-bodied fluid and spread fully, dissolve, mix, finally reach respectively to organize between the material and evenly mix.

Because adopted above technical scheme, the present invention has following beneficial effect:

1, adopts the rotation respectively of helical form agitator and pivoted arm, revolution, rotation is opposite with the revolution direction, the material eddy motion upwards promotes, gravitate moves downward again simultaneously, scraper plate is made the circumference revolution motion along the bucket wall, will adhere to material and separate with the bucket wall, both speed differences, make that mixing velocity and efficient are higher, about 1～4min just can mix fully.

Fig. 2 is the utility model one embodiment side-looking structural representation.

Among the figure: 10 agitators, 11 pivoted arms, 12 reductors, 13 motors, 14 gripper shoes, 15 packing_seals, 16 cheese head screws, the sealing of 17 felts, 18 bungs, 19 packing seats, 20 bearing glands, 21 cheese head screws and stop washer, 22 stavings, 23 ear framves, 24 swivel joints, 25 rotary flanges, 26 round ends, 27 bung flanges.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described

With reference to accompanying drawing 1, accompanying drawing 2, a kind of coaxial double stirrer device mixer, mainly partly form by motor, reductor, bung, staving, agitator, pivoted arm, frame and cylinder device etc., be fixed with reductor on the gripper shoe on bung top, the top of reductor is motor, round end is arranged on the below of gripper shoe, pivoted arm is fixed on the round end, agitator is fixed on the swivel joint, be provided with rotary flange between swivel joint and round end, motor, reductor, bung, hollow shaft, staving and the axis of rotation order series connection up and down link to each other with frame for one.

Fixing from top to bottom between (27) three parts of the gripper shoe (14) on reductor (12) and bung (18) top and bung flange by nut, gripper shoe (14) below is provided with packing seat (19), handle through packing_seal (15) between packing seat (19) and gripper shoe (14) and round end (26), round end (26) is arranged on the below of packing seat (19), be connected with pivoted arm (11) on the round end (26), rotary flange (25) is fixed on the round end (26) by cheese head screw (16), handle through felt sealing (17) between round end (26) and bearing gland (20), rotary flange (25) passes through the interior bearing fixing of its upper bearing (metal) gland (20) on the rotating shaft of motor (12), rotary flange (25) bottom is fixedly connected with swivel joint (24) with cheese head screw and stop washer (21), swivel joint (24) lower end is fixed with two spiral helicine agitators (10), and staving (22) is provided with ear frame (23).

Further, described pivoted arm and agitator, pivoted arm is connected with round end, be hollow shaft, during its revolution, make circular motion along the bucket wall, will separate with the bucket wall attached to the material on the bucket wall, agitator is connected with swivel joint, be the double helix band, its time rotational, the direction of rotating with pivoted arm is opposite, and speed is higher than revolution speed, under the effect of two kinds of speed, material forms powerful eddy current and convection current in the bucket, makes between the full-bodied fluid and spreads fully, dissolves, mixes, and finally reaches respectively to organize between the material evenly to mix.

With reference to accompanying drawing 1, accompanying drawing 2, according to mixing the class difference that requires, when not needing to carry out mixing under the vacuum, the material that needs are mixed drops into bucket, staving is positioned on the hand frame component, rise by control system control hand frame, after staving and bung are fixing, motor and reductor are started working, spiral helicine agitator begins with the certain speed rotation, material is under the effect of agitator, material has the radial whirl campaign and upwards promotes to motion, simultaneously material when moving upward because the self gravitation effect of material and moving downward, feasible mixing is quicker, evenly, in the agitator rotation, pivoted arm moves round about with friction speed, to separate with the bucket wall attached to the material on the bucket wall, in the process of mixing, can drop into required material at any time by dog-house as required, can use reductor to regulate the speed of rotation and revolution, material has formed strong eddy current and convection current under the effect of agitator and two kinds of speed of pivoted arm, makes diffusion fully between the full-bodied fluid, mix, finally reach the mixed uniformly target of each storeroom; When needs carry out under the vacuum married operation, stirring as battery, the composition mixing of medicine etc. are high-grade to be mixed, vacuum port utilization vacuum extractor by bung top carries out vacuum pumping, drop into material from dog-house then, carry out married operation then, and can be by the state of observation panel Real Time Observation mixing, so that carry out the operations such as interpolation of material in real time.

The present invention according to the mixing principle of fluid vortex, convection current, turbulent flow, shearing with the material rapid mixing, be mainly used in pasty material, liquid mixes with the solubility powder with liquid, liquid, the mixing velocity of product of the present invention is fast, the mixture homogeneity height, the full-bodied material of suitable various differences needs.
