The pipeline mixing device sequentially comprises a plurality of raw material input pipelines, a main pipeline and a pipeline mixer, wherein the raw material input pipelines are connected to the main pipeline respectively; the main pipeline is connected with the pipeline mixer; and a pipeline pump is arranged on the main pipeline, and is communicated with the main pipeline through a connecting pipeline. The pipeline mixing device has the advantages that the material mixing effect and the conversion rate during infancy of the polymerization reaction are improved, and the total polymerization time of the polymerization reaction and the production cost are reduced.
Description
Technical field
The utility model relates to a kind of polymkeric substance charging device, and particularly a kind of polymkeric substance feeds intake and uses pipeline mixing device.
Background technology
When existing polymkeric substance feeds intake; Only have line mixer to be used for the mixing of various materials, the mixed effect of various materials is also bad, and the transformation efficiency at polyreaction initial stage is lower; The reaction kettle transformation efficiency only has 2 ~ 5%; Cause the total polymerization time of polyreaction to increase, thereby the latex amount of producing under the same consumption energy situation reduce, and has increased unit cost.
The utility model of CN2767113Y discloses a kind of mixed with polymers device, comprises shell, connecting joint and mixtinite, and said shell inner cavity is installed mixtinite, and connecting joint is installed in the end.This mixed with polymers device still is single mixing tank setting, and the mixed effect of various materials is also bad, causes the transformation efficiency at polyreaction initial stage lower.
Summary of the invention
When the purpose of the utility model is that the existing polymkeric substance of solution feeds intake; Only there is single line mixer to be used for the mixing of various materials; The mixed effect and the transformation efficiency bad, the polyreaction initial stage of the various materials that exist is lower, the problem that the total polymerization time increases, production cost is high of polyreaction; Provide a kind of polymkeric substance to feed intake and use pipeline mixing device; Improve the mixed effect of material, improved the transformation efficiency of initial reaction stage, reduced the total polymerization time and the production cost of polyreaction.
The utility model solves the technical scheme that its technical problem adopted: a kind of polymkeric substance feeds intake and uses pipeline mixing device; Comprise the some raw material input channels, main pipe line and the line mixer that set gradually; Some raw material input channels are connected to main pipe line respectively; Main pipe line is connected with line mixer, and main pipe line is provided with in-line pump, and in-line pump is communicated with main pipe line through connecting tube.
The utility model had increased an in-line pump before line mixer; After increasing, improved by this in-line pump the mixed effect of material effectively; Make the transformation efficiency at polyreaction initial stage obviously raise (the 1st reaction kettle transformation efficiency reaches more than 10%); Thereby effectively reduce (comparing does not increase the residence time that has reduced by 1 ~ 2 reaction kettle before the in-line pump) total time that makes polyreaction, need 8 ~ 9 reaction kettles to react before increasing, and increase behind the in-line pump transformation efficiency that 7 ~ 8 reaction kettles even 6 reaction kettles reactions just can reach regulation; Unnecessary like this reaction kettle can cut out subsequent use; When polymerized unit or reclaim that the unit goes wrong and can form buffering to polymerized unit can not carry out the normal production order time, stir and also can close down, reduced power consumption; Thereby reduced unit cost, made that the economic benefit under the equal conditions improves.
As preferably, some raw material input channels are respectively de-oxygenised water input channel, divinyl input channel, vinyl cyanide input channel, concentrate water input channel and molecular weight regulator input channel.These input channels all are the raw material input channels that latex is produced.
As preferably, connecting tube is provided with ball valve, also is provided with ball valve on the main pipe line.Through ball valve is set, be convenient to when in-line pump breaks down, cut off pipeline, shift out in-line pump and keep in repair.
The beneficial effect of the utility model is: through before line mixer, having increased an in-line pump, improved the mixed effect of material, improved the transformation efficiency of initial reaction stage, reduced the total polymerization time and the production cost of polyreaction.
