Description

High-shear homogenizing machine

The utility model relates to a kind of homogenizer.

The fluid that runs in food, the light industry industry is to be grouped into by multiple one-tenth mostly, belongs to the heterogeneous body multiphase mixture, and the particle size of decentralized photo and the distribution under the stable state are the important symbols of end product quality.Though through stirring, hybrid technique, the spherical or non-spherical fiber size in the feed liquid still can not meet the demands, and is in particular in: product is fineless and smooth, system is unstable, the precipitated and separated phenomenon is serious.Utilize the homogenizer homogeneous can effectively alleviate above problem, feed liquid is fully mixed, the particulate refinement also evenly distributes, and to prevent the layering of liquid material, obtains the dispersion of height stable homogeneous.

Existing homogenizer has polytype: high pressure homogenizer, centrifugal type homogenizer, vacuum homogenizer and high-shear homogenizing machine etc.; high pressure homogenizer wherein is as a kind of traditional machinery; be widely used; but because the structure of high pressure homogenizer is unreasonable; generally also can only be used for handling all lower feed liquid of some concentration, viscosity; be not suitable for handling the liquid material that contains solid particle or fiber; so homogeneous in the market some novel foodstuffs; effect is bad; and its complex structure; the cost height, energy consumption is big, and maintenance is inconvenient.In recent years, high-shear homogenizing machine with its unique high shear mechanism and efficiently homogenizing effect just progressively substitute the conventional high-tension homogenizer, and demonstrate its superiority.

The key structure of high-shear homogenizing machine is the stator and the rotor of a pair of precision-fit, its primary structure form is that stator and rotor are pectinate texture, layer intersects mutually with interlayer during installation, under the high-speed driving of motor, high-speed motion in the slit gap of material between rotor and stator, form turbulent flow, material reaches the effect of dispersion, pulverizing under comprehensive functions such as fluid power shearing, centrifugal extruding.But in existing this class homogenizer, the broach of its stator and rotor is rectangular configuration, in case wearing and tearing can't be adjusted, in addition, a number of its pectinate texture can not be regulated by actual requirement.

The purpose of this utility model is a kind of high-shear homogenizing machine that can regulate easily of design, to improve homogenizing effect, convenient manufacturing, I﹠M.

Its main technical schemes comprises utilizes bearing to be installed on main shaft on the bearing, the pump housing is arranged on bearing, the part that is positioned at the pump housing on main shaft is installed the rotor that has axial comb halogen, tighten the stator that connection has axial broach at the pump housing, stator and the rotor cutting member that partners, import and export is set on the pump housing, the radially section configuration that it is characterized in that broach for from its root to the diminishing trapezoidal broach of head, be provided with to adjust at the end face of rotor and main shaft connecting portion and encircle.

Cutting member has at least a pair of, has a circle on the end face of each rotor and stator at least along circumferential equally distributed axial broach, and, stator staggers mutually, cooperates with epitrochanterian each circle broach, one annular cavity is arranged between inner ring broach and main shaft, and rotor is blade-carrying impeller near the root of main shaft, and this impeller is positioned at inner chamber, between rotor and another stator, exocoel is arranged, in the middle part of the end face of stator and between main shaft the circular passage is being arranged cutting member.

The pump housing can be installed on the end of bearing, and the outlet that setting is communicated with exocoel on the pump housing, stator is made of barrel-shaped body and end face, all the other several pump housing shells of body double as to cutting member, stator in a pair of cutting member of outermost is made of end cap, and at the middle part of end cap the import that is communicated with inner chamber is set.

Top at bearing is provided with porous plug.Main shaft utilizes left and right bearing to be installed on the bearing, and left and right bearing utilizes the left and right bearing (ball) cover positioning and fixing in its outside respectively, and utilizes screw to be connected and fixed lasso on the main shaft in the left bearing outside.End face outer rim at stator is provided with seal groove, places sealing ring in the groove, and the other end inboard with respect to end face on the body of stator is provided with positioning step.

The utility model has the advantages that broach is designed to stepped tooth after, can encircle the gap of regulating between broach by adjusting on request, to satisfy the homogeneous requirement of different medium, in use for some time, become big if find its gap, just can encircle and repair its gap by the adjustment of changing different in width; Secondly, because the stator design in the cutting member is become tubbiness, its body double as pump housing shell, this structure makes the number of cutting member to make up arbitrarily, to satisfy different requirements with after rotor structure combines; Behind the edge blade of the middle part of rotor, can strengthen the suction capactity and the stirring capacity of entire pump.
