Abstract
The present invention discloses a static mixer for powder granules, which is characterized in that concentric tapered pipes which internally contact an outer pipe are arranged axially at intervals according to a certain circumferential angular difference in an outer hollow pipe. The direction arrangement of a mixing unit is consistent, and a big end of the mixing unit is a material inlet. Compared with the existing powder granule mixer, the static mixer has the advantages of simple structure, high mixing efficiency, low cost, simple and direct assembly and accurate location, and the mixing unit can be replaced. The present invention is widely suitable for mixing various powder granules by the aid of gravity or pneumatic transportation, and the present invention is also suitable for powder granules with strong adhesive force and other fluid media.
Description
The present invention relates to a kind of static mixer, specifically a kind of powder body medium that can be used for acts on the static mixer that flow process carries out by gravity or strength.
Static mixer that uses in the prior art such as U.S. Luo Si ISG type blender, four holes of employing cell cube are scurried logical at a certain angle, are positioned at periphery at the inflow end, then are in the centre at outflow end and reach the mixing purpose.Toray company Hi-mixer is provided with leaf unit and medial compartment that insertion is twisted into 90 ° to the left or to the right in two passages, and staggers 90 ° to arrange and realize mixing.United States Patent (USP) then assembles in the square tube of hollow for No. 3583678 cuts apart plate and displacement plate, and their cross arrangements are vertically mixed.Chinese patent 85106712A powder-granule static mixer alternately is provided with coniform blade in vertical cylinder and truncated cone-shaped leaf reaches the mixing purpose.
Task of the present invention is to provide a kind of simple in structure, is convenient to manufacture, installation, maintenance, and is cheap, and the mixing in the time of can not only being used for the powder body and carrying by gravity effect or strength is also applicable to the static mixer of other fluid media (medium).
Task of the present invention is finished as follows, in the straight tube of a hollow, be arranged with one or more groups Concentric Reducers as the mixed cell body, every group of unit number has patterns such as three, four, eight, each adjacent cells keeps at a certain distance away vertically, and the certain angle that circumferentially staggers is connected with the outer tube inscribe.Mixed cell is connected employing after outer tube and the boring of Concentric Reducers straight section correspondence position with outer tube, passes from inside to outside outside the pipe with bolt, connects with nut; Or will connect at pipe external application screw after institute's boring difference tapping; Concentric Reducers concentric reducer direction is consistent arranges and big end is material inlet, and there are flange or screw thread in the outer tube two ends so that be installed on the conveying pipeline line.During mixing, powder body material with given proportioning enters horizontal or vertical conveying pipeline from charging gear or Pneumatic conveyer, the blender that flows through by gravity or strength generation, produce mechanism effect such as cut apart mutually, move the position, converge again through mixed cell, can obtain uniform mixture in the exit of conveying pipeline.
The present invention is applicable to the mixing of various powder bodies, and is as the mixing of the powder body medium of industries such as cement, building materials, oil, chemical industry, light industry, powder metallurgy, food, pharmacy, also applicable for medium and other fluid media (medium) that adhesion is stronger.
The present invention compared with the prior art, structure is more simple, only needs a kind of mixed cell; Adopt the outer assembling mode that connects of pipe, be easy to manufacturing, operation, the cleaning easy maintenance; And have the mixed cell accurate positioning, the advantage of automatic capturing direction, and can be changed easily; Its passage is more level and smooth, and resistance is little, the mixing efficiency height, and the scope of application is wider; Mixed process and course of conveying are carried out synchronously, realize the miniaturization that technology is continuous, efficient, laborsaving, energy-conservation and install, and eliminate unusual the delay and clogging of powder body that similar blender easily produces.
The present invention is described in further detail below with reference to accompanying drawing.
Fig. 1 is that three unit are one group mixed cell arrangement architecture pattern schematic diagram.
