Description
Technical field
The utility model relates to the material handling apparatus after a kind of caffeine hydrogenation reduction, produce for chemical pharmaceutical
Field.
Background technique
Theophylline sodium salt is the important intermediate for producing theophylline and caffeine, and theophylline is to pass through condensation, cyclization, Asia by cyanoacetic acid
Change, plus hydrogen, acylation, closed loop and etc. generation, production process is cumbersome, and intermediate steps are more.Wherein hydrogenation reaction is by certain dense
The murexide of degree generates the process of DAU under the catalysis of Raney's nickel through hydrogen reducing.Since Raney's nickel is at high cost and repeatable benefit
With, in production using filtering machine with horizontal blade in material after hydrogenation reaction Raney's nickel and feed liquid separate, utilize level
Raney's nickel is retained down by leaf-type filter, and the DAU feed liquid after separating enters acylated tank and carries out next step reaction, and Raney's nickel is used
Vacuum back suction enters plus hydrogen tank continues to use.
Presently used filtering machine with horizontal blade, discharge pipe are located at the middle and lower part of body, and the DAU of last consignment of is caused to expect
Liquid can not all flow into acylated tank, remaining material can be withdrawn into Raney's nickel plus hydrogen tank in and with next group murexide
Hydrogenation reaction is carried out together, is had an adverse effect to hydrogenation reaction, so that impurity enriched, reduces and add hydrogen yield and quality.
Utility model content
The technical problem to be solved by the present invention is to provide at the material after a kind of hydrogenation reduction for caffeine
Device is managed, the material residual and time set after effectively preventing filters pressing improve thus the problem of influencing next group material hydrogenation reaction
Quality of material and yield.
In order to solve the above technical problems, technical solution adopted in the utility model is:
A kind of material handling apparatus after the hydrogenation reduction for caffeine, including there is cylindrical upper shell and back taper
The filtering machine with horizontal blade of shape lower shell；The side wall bottom end of the upper shell is equipped with feed pipe, and the bottom of the lower shell is set
There is coupled logical surge tank, the bottom of surge tank is equipped with catalyst recovery channel, the opposite end point on the side wall of surge tank
Not She You discharge pipe and flushing pipeline, and discharge pipe is also communicated with outlet conduit close to one end of surge tank.
Further, the top of the upper shell is equipped with cover.
Further, the surge tank is cylinder.
Further, the flushing pipeline is located at surge tank close on the side wall of its tank bottom, and discharge pipe is located at jet water spout
The top in road.
Further, valve is equipped on each pipeline.
The beneficial effects of adopting the technical scheme are that
On the one hand the utility model eliminates the residual of material, prevented upper batch materials to the unfavorable shadow of next batch reaction
It rings, improves product quality, increase hydrogenation reaction yield；On the other hand the cleaning and recycling of catalyst are realized, is reduced
The inactivation of catalyst, reduces the catalyst additional amount of every batch of, and catalyst 1kg, 12000 yuan/month of save the cost are added in every batch of reduction；Together
When provide the working environment of neat and tidy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, filtering machine with horizontal blade, 2, surge tank；3, feed pipe, 4, discharge pipe, 5, flushing pipeline, 6, go out
Waterpipe, 7, catalyst recovery channel.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, the utility model discloses the material handling apparatus after a kind of hydrogenation reduction for caffeine,
Including the filtering machine with horizontal blade 1 with cover, cylindrical upper shell and back taper lower shell.The side wall bottom end of upper shell is equipped with
Coupled logical feed pipe 3, the bottom of lower shell are equipped with coupled logical surge tank 2, and surge tank 2 is cylinder, delay
The bottom for rushing tank 2 is equipped with coupled logical catalyst recovery channel 7, the opposite end on the side wall of surge tank 2 be respectively equipped with
Its discharge pipe 4 and flushing pipeline 5 for being connected, and discharge pipe 4 is also communicated with outlet conduit close to one end of surge tank 2
6, valve is equipped on each pipeline.
Flushing pipeline 5 is located at surge tank 2 close on the side wall of its tank bottom, and discharge pipe 4 is located at the top of flushing pipeline 5.
The main body of the utility model include filtering machine with horizontal blade 1 and the bottom for being located at filtering machine with horizontal blade 1 and and its
The surge tank 2 being connected.Feed pipe 3 is located on the upper shell of filtering machine with horizontal blade 1, and discharge pipe 4, goes out flushing pipeline 5
Waterpipe 6 and catalyst recovery channel 7 are each provided on surge tank 2.The material that Raney's nickel and feed liquid are mixed with after hydrogenation reaction passes through
Feed pipe 3 enters filtering machine with horizontal blade 1, and the feed liquid after catalyst is trapped enters in surge tank 2 and by 2 side wall of surge tank
Discharge pipe 4 enter in acylated tank；It is rushed by flushing pipeline 5 into surge tank 2 and filtering machine with horizontal blade 1 after binder
Enter drinking water, opening compression seethes catalyst in filtering machine with horizontal blade 1, falls into catalyst in surge tank 2, another
Aspect plays the role of rinsing catalyst, and the water for finally washing catalyst is discharged through outlet conduit 6, and catalyst is anti-through catalyst recovery channel 7
It pushes up back and adds hydrogen tank, participate in next group hydrogenation reaction.
On the one hand the utility model eliminates the residual of material, prevented upper batch materials to the unfavorable shadow of next batch reaction
It rings, improves product quality, increase hydrogenation reaction yield；On the other hand the cleaning and recycling of catalyst are realized, is reduced
The inactivation of catalyst, reduces the catalyst additional amount of every batch of.In practice, catalyst 1kg, save the cost 12000 are added in every batch of reduction
Member/the moon；The working environment of neat and tidy is provided simultaneously.
