Abstract
This practicality provides a kind of process system preparing 4-hydroxyl-2-oxo-pyrrolidine acetamide, comprise reactor (1), dog-house is arranged at the top of this reactor, it is characterized in that, also comprise charging device, this charging device comprises pallet (2), infundibular body (3), batch feeding end (3), material table top (7); Described batch feeding end (3) is suitable with described dog-house.This practicality is applicable to pharmacy, cosmetics and field of fine chemical.
Description
Technical field
This practicality relates to a kind of chemical reaction equipment, is specifically related to a kind of process unit preparing chloro-3 3-hydroxyethyl butyrates of 4-.
Background technology
4-hydroxyl-2-oxo-pyrrolidine acetamide, trade name Oxiracetam is nootropic agents of new generation, belongs to novel pyrrolidinone compounds, is synthesized first by Italian SmithKline than Qie Mu company in 1974, listing in 1987.External listing formulation has capsule, powder, oral liquid, injection etc., and China succeeds in developing capsule in 1997.The dilatation of Oxiracetam market is rapid.In preparation 4-hydroxyl-2-oxo-pyrrolidine acetamide process, relate to solid-state supplementary material to feed intake problem, current feeds intake in link, directly material is dropped into from reactor feed mouth by operating personnel, when inventory is large, increases the labour intensity of operating personnel, and when feeding intake, easily cause material to scatter at reactor periphery, whether the amount fed intake accurately is impacted, affects yield and the quality of product.
Summary of the invention
In order to solve the problem, it is high that this practical purpose is to provide a kind of efficiency, the process unit of the 4-hydroxyl-2-oxo-pyrrolidine acetamide that liquid holdup few time of staying is short.
A kind of process system technical scheme preparing 4-hydroxyl-2-oxo-pyrrolidine acetamide that this practicality provides:
A kind of process system preparing 4-hydroxyl-2-oxo-pyrrolidine acetamide, comprise reactor (1), dog-house is arranged at the top of this reactor, it is characterized in that, also comprise charging device, this charging device comprises pallet (2), infundibular body (3), batch feeding end (4), material table top (7); Described batch feeding end (4) is suitable with described dog-house.
As preferably, described material table top (7) is provided with weight scale.
As preferably, described material table top (7) is equipped with side plate washer (6), also comprises scraping wings (8), this scraping wings (8) middle slip in described side shield (6); The horn mouth of described infundibular body (3) and the one side of described material table top (7) suitable.
As preferably, pulley (5) is equipped with in the bottom of described pallet (2).
The Advantageous Effects of this practicality:
This practicality adopts charging device, and the material that operating personnel will throw is placed on material table top, can human-saving, material table top has weight scale simultaneously, can accurately take thrown material, avoids throw or few throwing more; Side shield on material table top can prevent material from scattering ground, and the material on material table top can be advanced reactor from dog-house by scraping wings, avoids operating personnel directly to hold contact in hands.Pulley is equipped with in the bottom of pallet, can facilitate movement, for multiple stage reactor feed, greatly saves artificial, enhances productivity, guarantee the accuracy of inventory, guarantee processing quality, reduce material to the occupational hazards of operating personnel.
Accompanying drawing explanation
Fig. 1 is practical outside schematic diagram;
Fig. 2 charging device partial schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth this practicality further.Should be understood that these embodiments are only not used in the scope limiting this practicality for illustration of this practicality.
Embodiment 1
As shown in Figure 1, 2, a kind of process system technical scheme preparing 4-hydroxyl-2-oxo-pyrrolidine acetamide of providing of this practicality:
Prepare a process system for 4-hydroxyl-2-oxo-pyrrolidine acetamide, comprise reactor 1, dog-house is arranged at the top of this reactor, also comprises charging device, and this charging device comprises pallet 2, infundibular body 3, batch feeding end 4, material table top 7; Described batch feeding end 4 is suitable with described dog-house.In the present embodiment, material table top 7 is provided with weight scale, and material table top 7 is equipped with side plate washer 6, also comprises scraping wings 8, and this scraping wings 8 is at the middle slip of described side shield 6; The horn mouth of described infundibular body 3 and the one side of described material table top 7 suitable; As preferably, pulley 5 is equipped with in the bottom of described pallet 2.
This practicality adopts charging device, and the material that operating personnel will throw is placed on material table top 7, can human-saving, material table top 7 has weight scale simultaneously, can accurately take thrown material, avoids throw or few throwing more; Side shield 6 on material table top 7 can prevent material from scattering ground, and the material on material table top 7 can be advanced reactor 1 from dog-house by scraping wings 8, avoids operating personnel directly to hold contact in hands.Pulley is equipped with in the bottom of pallet 2, can facilitate movement, feeds intake for multiple stage reactor 1, greatly saves artificial, enhances productivity, guarantee the accuracy of inventory, guarantee processing quality, reduces material to the occupational hazards of operating personnel.
Present specification describes some embodiments, but should be understood that those skilled in the art pass through to read the various improvement that this description can know design and the scope not deviating from this practicality.Therefore, these other embodiments also should be included within the scope of appended claims.
