Description
Technical Field
The utility model relates to a powder liquid mixing apparatus technical field, specific integrated sled dress structure of ejector blender that says so.
Background
At present, a powder and liquid mixer is widely applied to the processing and manufacturing fields of food, medicine, chemical industry, synthetic fiber, environmental protection and the like, and is used for uniformly mixing powder and liquid according to a certain proportion so as to form a homogenized solution or slurry product.
The invention with the authorization notice number of CN103432918B discloses a powder and liquid dissolving mixer, and the technical scheme and the working principle of the invention are as follows: liquid is input quantitatively at a fixed pressure through a liquid infusion pipe, the liquid rapidly enters an enlarged mixing chamber in a left/right rotating shape through a left/right spiral blade fin in a first diameter-reducing pipeline with a reduced pipe diameter, a powder pneumatic conveying pipe is inserted into the middle part of the enlarged mixing chamber, powder is quantitatively input into a squirrel cage mixing mechanism arranged in the enlarged mixing chamber through pneumatic force, and powder-containing gas in the liquid in the squirrel cage mixing mechanism is bubbled, overturned, rotated left/right, dissolved and mixed in the liquid under the double action of gas-liquid kinetic energy. The squirrel-cage mixing mechanism plays roles of retarding rotation and facilitating stirring, so that the dissolution and mixing of powder are accelerated. And the dissolved liquid enters a second reducing pipeline containing a right/left spiral blade wing, and the liquid forms baffling along the right/left spiral line to further dissolve, homogenize and mix the powder. The mixed liquid flows into a liquid storage barrel.
It can be seen that the invention has the disadvantages that ① powder is pneumatically input into the enlarged mixing chamber to be mixed with liquid, a large amount of air also enters the enlarged mixing chamber to be mixed with the liquid, so that a large amount of bubbles are generated in the liquid, gas-liquid separation is needed subsequently, ② bubbles contain dust, and bubble films separate the liquid from the dust in the bubbles, so that the powder and the liquid are not favorably mixed and dissolved, ③ the solution after the powder and the liquid are mixed possibly contains small powder clusters which are not completely dissolved, and the small powder clusters can only be dissolved in the solution by natural force in a liquid storage barrel, so that the quality of the powder and the liquid mixed and dissolved is influenced.
In order to solve the above technical problem, CN 109364776 discloses an invention patent application of a powder-liquid mixer, and the structure also has the following disadvantages: the mixed solution of the powder and the liquid probably contains small powder lumps which are not completely dissolved, and the small powder lumps can be dissolved in the solution only by natural force in the liquid storage barrel, so that the quality of the mixed solution of the powder and the liquid is influenced, the mixing time is long, and the electric energy is wasted.
Moreover, at present, the existing powder-liquid mixers are all mixed by a single circulation, and the substantial defects of the single circulation mixing are as follows: the dissolution was incomplete and mixing with high concentration and high dispersibility could not be achieved.
