Problems solved by technology

[0004] The traditional mixing equipment can also mix the pellets by rotating the spiral blade. In addition to the dead angle, the surrounding of the rotating blade is easy to be glued by the liquid medicine and it is difficult to mix evenly.

Embodiment 1

[0028] Such as figure 1 As shown, the asymmetric double-cone quantitative jet liquid mixer includes a cylinder body 1, a main rotating shaft 2 connected to the cylinder body, and a power device 3 for driving the main rotating shaft 2 to rotate.

[0029] This embodiment also includes a support frame 7 on which both ends of the main rotating shaft are arranged. When the power unit 3 is in operation, it drives the main rotating shaft on the support frame 7 to rotate, thereby driving the cylinder 1 to rotate.

[0030] Such as figure 2 As shown, in this embodiment, the cylinder body 1 is a cavity composed of an upper cone 11 , a main body 12 , and a lower cone 13 that are connected sequentially from top to bottom and communicated internally as a whole. The top of the upper cone 11 is provided with an inlet 8 , and the bottom of the lower cone 13 is provided with an outlet 9 . Wherein, the lower bottom surface 21 of the upper cone is in contact with the upper bottom surface of t...

Embodiment 2

[0035] The present embodiment is basically the same as Embodiment 1, and its difference is only: the radius of the upper bottom surface 20 of the upper cone is defined as R1, the body cylinder (i.e. the radius of the lower bottom surface 21 of the upper cone, that is, the radius of the lower cone) The radius of the upper bottom surface 22) is defined as R2, and the radius of the lower bottom surface 23 of the lower cone is R3. The length relationship of R1, R2 and R3 satisfies the following condition: R1=R3=1 / 6R2. When R1=R3=1 / 6R2, the inventor has found through many tests that when R1=R3=1 / 6R2, the mixing effect of EVA pellets and liquid medicine is the best after the equipment is in operation. It can greatly shorten the curing time of EVA film and reduce its curing temperature.

Abstract

The invention discloses an asymmetric bipyramid mixer for quantitative liquid spray. The mixer comprises a barrel (1), a main rotary shaft (2) connected with the barrel, and a power device (3) for driving the main rotary shaft (2) to rotate. The main rotary shaft (2) is fixedly provided with a liquid medicine pipe (4) on the section in the barrel, the liquid medicine pipe is provided with a nozzle (5), and the main rotary shaft (2) is provided with an inner cavity (6) communicated with the liquid medicine pipe. For the asymmetric bipyramid mixer for quantitative liquid spray, no blind angle is left by the rotation of the whole barrel on the one hand, and on the other hand, the asymmetric design at the two ends of the barrel enables the granules in the whole barrel to be always in a flow condition and fully mixed in a full range.

Description

technical field [0001] The present invention relates to the production equipment of solar battery EVA adhesive film, specifically, the present invention relates to the production process of solar battery EVA adhesive film and is used for the granular material mixing in the production process of solar battery EVA adhesive film and is used for the non-symmetrical double-cone quantitative jet liquid mixing machine. Background technique [0002] The mixing process is the most important process in the production of EVA film for solar cells. Whether the mixing is sufficient and uniform directly affects the chemical properties of EVA, such as peel strength, cross-linking degree, aging resistance and so on. [0003] The commonly used mixing method is to add the prepared liquid medicine into the EVA pellets and stir properly so that the liquid and solid fine powder are in close contact with each other. The most commonly used mixing method is to rotate through a disc, cone or cylindric...
