Summary Box Box mixer mixer paddle mixer can be regarded as deformation, and its structure is solid, stir the material volume. Box-type agitator and vessel wall gap is small, is conducive to the heat transfer process, commonly used in heat transfer, crystallization operation and high-viscosity liquids, high concentration slurry and settling slurry mixing. Working principle and structure of the box-type agitator mixer box of larger diameter, the inner diameter of the reactor and generally 2/3 ~ 9 / 10,50 ~ 70r / min. Box-type agitator and vessel wall gap is small, is conducive to the heat transfer process, while rapidly rotating, agitator blades driven by the still liquid layer from the reactor walls brought down; slowly rotating, there scraper blender can produce good thermal conductivity. Box-type stirrer and connections similar to a paddle stirring shaft, i.e. the shaft end connected to the stirring impeller made semicircular collar, and then both sides of the two half-rings by bolts clamping the blade in the agitator shaft, while wearing a shaft with blades and bolts to secure the agitator shaft. Due to the large impeller outside dimensions, for ease of assembly and disassembly, is bolted between the blades most. Impeller with flat steel, angle, mostly manufactured in order to improve the strength of the impeller, may also reinforced steel. Stirring shaft with rungs, the assembled bars or welded connections between them, when the agitator shaft is rotatably driven gear motor to drive the material to achieve the level of the ring at different heights on the flow of rungs, the bars of the material to form an effective segmentation, reached the mandatory mixing and dispersing process results. Box mixer mixer box applications typically used in stir porridge-like material, stir revolutions in 60-130r / min is appropriate for a maximum viscosity of 200 ~ 300Pa · s. Applications box mixer typically running at low speed, low-viscosity liquid in the mixing does not produce a large shearing force, and therefore it is not suitable for liquid - liquid and gas - liquid dispersion. In another aspect, this kind of impeller flow moving in a large tank, the horizontal swirling flow dominates, does not have good mixing uniformity, but the flow rate in the vicinity of the tank wall than the other wheel, to achieve a large heat transfer film coefficient, Guchang for heat transfer, crystallization operation. In addition, due to the large diameter blade, and with the bottom of the tank close to, but also used it to stir the high concentration slurry and precipitation of slurry. There it is also commonly used in high-viscosity fluid mixing. Box mixer flow conditions at different levels on the ring height to flow. Structural frame anchor mixer with connections similar to paddle agitator shaft, impeller and agitation that connect one end of the shaft collar made semicircular, and two half-rings on both sides of the blade bolt clamping the agitator shaft while wearing a shaft with blades and bolts to secure the agitator shaft. Due to the large impeller outside dimensions, for ease of assembly and disassembly, is bolted between the blades most, only a small use of cast or welded. Impeller with flat steel, angle, mostly manufactured in order to improve the strength of the impeller, may also reinforced steel. Electrical control box mixer: Press to manually configure the control box, can interface with PLC, also be configured according to user requirements.
