Description
Technical field
The utility model relates to chemical reagent to purify filling apparatus technical field, specifically a kind of higher boiling chemistry examination
Agent purifies filling apparatus.
Background technique
The chemical reagent of domestic liquid type is mainly based on packing, strict demand due to chemical reagent to product index,
The standard of packing is not achieved in many raw materials, it is necessary to be purified.The chemical reagent of common liq class can be by way of distillation
It purifies, can but encounter problems to the purification of high boiling liquid, such as existing heating method is that steam heats, vapor (steam) temperature
It is difficult to reach the evaporating temperature of material at 120-150 DEG C, purchase equipment need to be led using electric heating, and the chemical reagent of liquid type is more
For flammable liquid, equipment safety grade need to be greatly improved;Production batch is small, so laboratory preparation can only be used, but laboratory
Preparation method yield is too low and does not catch up with the needs in market, and chemical reagent is wide in variety, it is impossible to accomplish that a set of equipment only produces a product
Kind, multi-purpose content, an object multipotency are needed, the equipment junction purchased in the market is to be fixedly connected, and dismounting is inconvenient, is not easy clear
It washes, existing production model is that workshop will be packed into big packaging after the purification of high boiling liquid chemical reagent, then send to packaging vehicle
Between carry out filling, since high boiling liquid chemical reagent freezing point is also high, has often just solidified or become when sending to packing shop
It is sticky, can only be heated to certain temperature again makes that it melts or viscosity reduction carries out filling again, reduces efficiency, increases energy
Consumption.
