Description

Technical Field

[0001] The utility model belongs to the technical field of microporous filter membrane material preparation, and particularly relates to a microporous filter membrane material preparation mixing mechanism. Background Art

[0002] Microporous membranes are widely used in scientific research, food testing, chemical industry, nanotechnology, energy and environmental protection and many other fields. Microporous membranes are mainly made of refined nitrocellulose, with appropriate amounts of cellulose acetate, acetone, n-butanol, ethanol, etc. They are hydrophilic, non-toxic and hygienic. They are a porous membrane filter material with a relatively uniform pore size distribution and penetrating micropores, and the microporosity is as high as 80‰ of the absolute pore size.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: when preparing microporous filter membrane materials, the raw materials required for preparation need to be processed into particles required for preparing microporous filter membranes through processes such as crushing and mixing. However, the current mixing facilities for preparing microporous filter membrane materials usually separate the crushing and mixing processes, that is, after the raw materials are crushed by the crushing mechanism, they need to be sent to the mixing mechanism through the intermediate conveying mechanism, and the use of the conveying mechanism leads to a waste of production time and an increase in processes, thereby reducing efficiency.

[0004] Therefore, we propose a mixing mechanism for preparing microporous filter membrane materials to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a mixing mechanism for preparing microporous filter membrane materials. Through the coordinated use of a first motor and a second motor, the two steps of crushing and mixing are completed simultaneously in a mixing box, thereby improving production efficiency and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A mixing mechanism for preparing microporous filter membrane materials, comprising a mixing box and a mixing module located on the mixing box, a feeding pipe is fixedly welded on one side of the top wall of the mixing box, a discharging pipe is welded at the center of the bottom wall of the mixing box, an inner crushing pipe connected to the feeding pipe is welded on the top wall of the inner cavity of the mixing box, a first motor is horizontally installed on one side wall of the inner crushing pipe, an output shaft of the first motor is connected to an inner shaft, a plurality of crushing blades distributed at equal intervals are welded on the inner shaft, and an oblique discharging nozzle is fixedly connected to the bottom of the inner crushing pipe;

[0008] The mixing module includes a second motor vertically installed at the center of the top wall of the mixing box, a vertical support shaft coaxially connected to the output shaft of the second motor, a plurality of sleeves welded to the vertical support shaft, and stirring blades respectively installed on the plurality of sleeves. A material tray is also fixedly welded on the vertical support shaft, wherein the material tray is rotated and cut along its axis to form an annular inner groove located below the oblique discharge nozzle, and a plurality of distribution openings distributed in a circular array along the center axis of the material tray are formed on the bottom wall of the annular inner groove. The material can be dispersed through the annular inner groove and the plurality of distribution openings, and spread more evenly throughout the inner cavity of the mixing box. Both the first motor and the second motor require power supply from external power facilities.

[0009] As a preferred embodiment, the inner shaft connected to the first motor is located in the inner crushing tube, and the inner shaft is rotatably connected to the inner crushing tube; so that when the first motor is powered on, it can drive the inner shaft and the multiple crushing blades thereon to operate stably.

[0010] As a preferred embodiment, a plurality of sleeves are evenly spaced in the vertical direction, and two stirring blades are symmetrically welded on each sleeve, so that the sleeve and stirring blade structure remain stable.

[0011] As a preferred embodiment, a bottom support rod is welded at the bottom of the inner cavity of the mixing box, wherein the vertical support shaft is rotatably connected to the bottom support rod, so that the bottom structure of the vertical support shaft remains stable and can operate stably.

[0012] As a preferred embodiment, material guide seats are welded on the four sides of the bottom wall of the inner cavity of the mixing box, and the facing ends of the four material guide seats lead to the discharge pipe; thus, the prepared material can be discharged from the discharge pipe through the four material guide seats.

[0013] As a preferred embodiment, support feet are installed at the four corners of the bottom wall of the mixing box, so that the mixing box and the structure above it remain stable.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The microporous filter membrane material preparation mixing mechanism, through the cooperation of the first motor and the second motor, completes the two steps of crushing and mixing in the mixing box at the same time, and the freshly crushed raw materials are directly and evenly scattered throughout the mixing box through the material tray and stirred by the stirring blades, thereby eliminating the intermediate conveying process and improving the production efficiency;

[0016] The microporous filter membrane material preparation mixing mechanism has a first motor that drives a plurality of crushing blades to rotate at high speed to crush the raw materials. After crushing, the raw materials fall into the annular inner groove through the inclined discharge nozzle. The operation of the second motor causes the vertical support shaft, the material plate and the plurality of stirring blades to rotate at a uniform speed. After the materials fall into the annular inner groove, they are dispersedly thrown out through the plurality of material distribution ports and fall in various places in the inner cavity of the mixing box and are evenly distributed.
