Abstract
The utility model discloses a kind of trifluoroacetic ethyl acetoacetate production filter-pressing device, comprise synthesis reaction vessel, tundish and rectifying still, described synthesis reaction vessel, tundish are connected successively with rectifying still, a strainer is added with between described tundish and rectifying still, described rectifying still connects a plate and frame(type)filter press, and described plate and frame(type)filter press connects storage tank and loft drier successively.The utility model changes traditional whizzer into plate and frame(type)filter press, decreases distributing of feed liquid taste in drying process, environmental protection more, and press filtration effect is more thorough, reduces the loss of material; Set up a strainer, feed liquid, before entering rectifying still, is first filtered, and by removals such as some mechanical impuritys, improves the purity of material after rectifying.Air compressor machine passes into high-pressure air by high air pressure passages in plate and frame(type)filter press, in dry materials process, can dry up further material, improves press filtration effect, reduces the water ratio of material, can save energy during follow-up drying.
Description
Technical field
The utility model belongs to field of chemical equipment, is specifically related to a kind of trifluoroacetic ethyl acetoacetate production filter-pressing device.
Background technology
Trifluoroacetic ethyl acetoacetate is the important intermediate of the fluorochemicals such as synthetic pesticide, medicine, take trifluoroacetic ethyl acetoacetate as raw material or as key intermediate, can produce all kinds of containing ring medicine, efficient pesticides and highy potent herbicide, or obtain the important intermediate of synthesizing these products.At present, trifluoroacetic ethyl acetoacetate many employings synthetic method obtains, after synthesis reaction vessel reaction, need feed liquid to carry out drying, existing drying generally adopts whizzer, and feed liquid is carried out preliminarily dried, this method not only taste causes environmental pollution greatly, easily, and material loss is large.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of trifluoroacetic ethyl acetoacetate production filter-pressing device, can alleviate taste in drying process, material loss is few, not easily to environment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of trifluoroacetic ethyl acetoacetate production filter-pressing device, comprise synthesis reaction vessel, tundish and rectifying still, described synthesis reaction vessel, tundish are connected successively with rectifying still, a strainer is added with between described tundish and rectifying still, described rectifying still connects a plate and frame(type)filter press, and described plate and frame(type)filter press connects storage tank and loft drier successively.
Further, described rectifying still is connected a high air pressure passages with on the pipeline between plate and frame(type)filter press, described high air pressure passages is connected with an air compressor machine, and described high air pressure passages is provided with an air flow valve, for controlling the air capacity entering plate and frame(type)filter press.
Further, the liquid outlet of described plate and frame(type)filter press connects a container for storing liquid, described container for storing liquid is connected with synthesis reaction vessel, pipeline between described container for storing liquid and synthesis reaction vessel is provided with flow pump, feed liquid after plate and frame(type)filter press press filtration can be stored, and then pump into synthesis reaction vessel and react further.
The beneficial effects of the utility model are: filter-pressing device of the present utility model, change traditional whizzer into plate and frame(type)filter press, the distributing of feed liquid taste in drying process before decreasing, environmental protection more, and press filtration effect is more thorough, reduces the loss of material; Set up a strainer, feed liquid, before entering rectifying still, is first filtered, and by removals such as some mechanical impuritys, improves the purity of material after rectifying.Air compressor machine passes into high-pressure air by high air pressure passages in plate and frame(type)filter press, in dry materials process, can dry up further material, improves press filtration effect, saves the energy, reduces the water ratio of material, can save energy during follow-up drying.Feed liquid after pressure filter press filtration is first collected by hold-up vessel, then by pump, feed liquid is pumped into synthesis reaction vessel and carry out secondary response again, is recycled by mother liquor, substantially increases the utilization ratio of material.
