Abstract
The invention provides a device for feeding a solid material in a reaction kettle. The device comprises a hopper and a charging barrel positioned below the hopper, wherein a first brake valve is arranged between the hopper and the charging barrel; the lower end of the charging barrel is connected with a feeding hole formed in a kettle cover through a second brake valve, and the upper end part of the charging barrel is connected with a compressing nitrogen supply pipe which is provided with an air valve so as to blow the charging barrel; the device provided by the invention comprises the hopper, the first brake valve, the charging barrel and the second brake valve, which are sequentially connected from top to bottom, and the second brake valve is connected with the feeding hole formed in the kettle cover, the first brake valve, the second brake valve and the air valve are all in a closing state before feeding, the first brake valve is opened when feeding is performed, a pre-fed material is added into the hopper and falls in the charging barrel, and then the first brake valve is closed; the second brake valve and the air valve are opened, and the material is added in the reaction kettle through nitrogen purging, so that the feeding operation is finished. The device provided by the invention has the advantages that the space in the kettle and the space outside the kettle are isolated through the valves in a feeding process, solvent gas is avoided escaping, and safe and environment-friendly effects in feeding can be achieved.
Description
technical field
The present invention relates to a kind of device to throwing solid material in reactor.
background technology
In organic synthesis process, sometimes need to adding solid material in the reaction feed liquid under fluidized state in reactor.Current feeding mode is the dog-house of directly opening reactor, directly feeds intake.This feeding mode causes reactor and external environment to be directly communicated with, and reactor internal solvent gas is escaped into outside still by space in still, causes air pollution and affects workers ' health, and organic solvent also likely sets off an explosion, and has potential safety hazard.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of device to throwing solid material in reactor.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of device to throwing solid material in reactor, comprise hopper and the barrel that is positioned at hopper below, the first gate valve is set between hopper and barrel, barrel lower end is connected with the batching hole on kettle cover by the second gate valve, and the upper end of barrel connects compressed nitrogen supply pipe with air valve to purge barrel.
The above-mentioned device to throwing solid material in reactor, barrel outside is also provided with the vibrator that beats barrel.
The above-mentioned device to throwing solid material in reactor, vibrator is pneumatic hammer.
The above-mentioned device to throwing solid material in reactor, hopper upper end is sealed by hopper cover.
The above-mentioned device to throwing solid material in reactor, material tube inner wall polishing.
The present invention includes the hopper, the first gate valve, barrel and the second gate valve that are connected in series in turn from top to bottom, the second gate valve is connected with the batching hole on kettle cover.Feed intake before operation, the first gate valve, the second gate valve and air valve are all in closed condition, while feeding intake operation, open the first gate valve, will add in advance material and add material bin and fall into barrel, then close the first gate valve, open the second gate valve and air valve, by nitrogen blowing, material is added in reactor, complete and feed intake.In the process of feeding intake, in still, space and the still external space are isolated by valve, have avoided solvent gas effusion, and safety and environmental protection more makes to feed intake.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is schematic diagram of the present invention.
In figure: 1 hopper cover, 2 first gate valves, 3 barrels, 4 vibrators, 5 second gate valves, 6 air valves.
The specific embodiment
As shown in Figure 1, to the device of throwing solid material in reactor, comprise hopper and be positioned at the barrel 3 of hopper below, the first gate valve 2 is set between hopper and barrel, barrel lower end is connected with the batching hole on kettle cover by the second gate valve 5, and the upper end of barrel connects compressed nitrogen supply pipe with air valve 6 to purge barrel.
Barrel outside is also provided with the vibrator 4 that beats barrel, and nitrogen blowing and vibrator beat and make material noresidue in barrel.Particularly, vibrator is pneumatic hammer.
Particularly, hopper upper end is sealed by hopper cover 1.Material tube inner wall polishing.
