Abstract

The utility model relates to the field of mixing machines, in particular to a double-shaft paddle mixer, which comprises a mixing chamber, stirring shafts and paddles, wherein the stirring shafts include two parallel shafts, and are axially arranged in a cavity of the mixing chamber; the paddles are fixed on circumferential outer walls of the stirring shafts. The double-shaft paddle mixer is characterized in that the paddles are thin plates, and are fixed on the circumferential outer walls of the stirring shafts in a manner of annular arrangement with the stirring shafts as central shafts; the paddles on the two stirring shafts are in staggered arrangement at intersections; each paddle is provided with a plurality of small holes, which are arranged uniformly. The double-shaft paddle mixer obtained according to the utility model has the following beneficial effects: the thin-plate paddles increases the contact area of the paddles and a material in the mixing chamber, more material can be urged to move during rotation, thus providing a higher mixing efficiency; the small holes preset on the paddles are used for squeezing caking blocks in the material, thereby achieving more uniform mixing.

Description

Twin shaft paddle mixer

Technical field

The utility model relates to mixer field, relates in particular to twin shaft paddle mixer.

Background technology

Twin shaft paddle mixer is widely used in food, medicine, the fields such as chemical industry, its operation principle is: have two shafts that direction of rotation is contrary, on shaft, be provided with blade, and two the blade on shaft is staggered in intersection, material is done compound motion under blade stirs, thereby realize evenly, mix, the mixing efficiency of twin shaft paddle mixer is high, , but carry out in the mixed process of solid material, often run into the problem that still has caking after mixing of materials, this is due to the efficiency of only having considered how to improve stirring in twin shaft paddle mixer design process, but the function of having ignored crushing material, there is no to arrange the frame for movement of breaing up caking.

Summary of the invention

In order to address the above problem, the utility model provides twin shaft paddle mixer, comprise mixing chamber, shaft and blade, described shaft is parallel two and is axially erected in the chamber of described mixing chamber, described blade is fixed in the outer circumferential walls of described shaft, it is characterized in that, described blade is thin plate, and axle centered by described shaft, mode with annular array is fixed in the outer circumferential walls of described shaft, article two, the blade on described shaft is staggered in intersection, on described blade, be provided with a plurality of apertures, and described aperture is evenly distributed.

Mode with annular array in the outer circumferential walls of described shaft is evenly fixed with 3～6 described blades.

Described blade is fixed in the outer circumferential walls of described shaft or is directly welded in the outer circumferential walls of described shaft by screw and nut.

Described blade is rectangular thin plate or thin semicircular plate, and when described blade is rectangular thin plate, its length is less than the axial length of described shaft, and when described blade is thin semicircular plate, its diameter is less than the axial length of described shaft.

The twin shaft paddle mixer obtaining by the utility model, its beneficial effect is: laminal blade has increased the contact area of material in blade and mixing chamber, in rotary course, can drive more material movement, aperture default on blade is for squeezing the caking of broken material, in the time of near caking moves to aperture, around under the acting in conjunction of the gravity of material and blade agitation force, material caking is can be squeezed broken and converge through aperture and material around, under the continuous stirring of blade, also constantly cup is crowded broken for caking in material, thereby realized more uniformly, mix, the twin shaft paddle mixer that the utility model provides is simple and reasonable, can squeeze the caking in broken material, and the contact area of blade and material is large, thereby there is higher mixing efficiency.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

In figure: 1-mixing chamber, 2-shaft, 3-blade, 4-aperture.

Embodiment

As Figure 1-3, twin shaft paddle mixer, comprise mixing chamber 1, shaft 2 and blade 3, shaft 2 is parallel two and is axially erected in the chamber of mixing chamber 1, blade 3 is fixed in the outer circumferential walls of shaft 2, blade 3 is thin plate, and axle centered by shaft 2, mode with annular array is fixed in the outer circumferential walls of shaft 2, article two, the blade 3 on shaft 2 is staggered in intersection, on blade 3, be provided with a plurality of apertures 4, and aperture 4 is evenly distributed, mode with annular array in the outer circumferential walls of shaft 2 is evenly fixed with 3～6 blades 3, blade 3 is fixed in the outer circumferential walls of shaft 2 by screw and nut or is directly welded in the outer circumferential walls of shaft 2, blade 3 is rectangular thin plate or thin semicircular plate, and when blade 3 is rectangular thin plate, its length is less than the axial length of shaft 2, when blade 3 is thin semicircular plate, its diameter is less than the axial length of shaft 2.

Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
