Abstract
The utility model discloses a kind of double valve nitrogen pressurization charge pipe, belong to feeding device field.It includes reactor, loading hopper, charge pipe, upper valve, lower valve, high pressure nitrogen air inlet pipe, air intake valve, the loading hopper is by charge pipe with being connected at the top of reactor, the charge pipe top is provided with upper valve, charge pipe bottom is provided with lower valve, high pressure nitrogen air inlet pipe is connected with charge pipe between upper valve, lower valve, the high pressure nitrogen air inlet pipe is provided with air intake valve.By setting valve, lower valve on charge pipe, first close lower valve, valve is opened again, and loading hopper starts to feed to the inside of charge pipe, is then shut off valve, lower valve is opened again, the air intake valve of high pressure nitrogen air inlet pipe is opened simultaneously, and material is pressed into reactor by the air pressure of inert nitrogen gas, the whole sealing gas-tight of charging, it ensure that production environment is cleaned, and workman's is healthy.
Description
Technical field
The utility model is related to a kind of double valve nitrogen pressurization charge pipe, belongs to feeding device field.
Background technology
In chemical process, the intermediate product of some reactions is volatile toxic and harmful gas, be it requires anti-
It is sealed to answer kettle, but during charging, always inevitably has portion gas to be emerged from the charging mouth of pipe, harm charging
Workman's is healthy, also pollutes production environment.How to prevent gas during charging in reactor from leaking, be current urgent need solution
A problem certainly.
The content of the invention
Technical problem to be solved in the utility model is：A kind of double valve nitrogen pressurization charge pipe is provided, it is solved
The problem of toxic and harmful gas during charging in reactor is leaked.
Technical problem to be solved in the utility model takes following technical scheme to realize：
A kind of double valve nitrogen pressurization charge pipe, it includes reactor, loading hopper, charge pipe, upper valve, lower valve, height
Nitrogen inlet duct, air intake valve are pressed, the loading hopper at the top of reactor by charge pipe with being connected, and the charge pipe top is provided with
Upper valve, charge pipe bottom is provided with lower valve, the charge pipe between upper valve, lower valve and is connected with high pressure nitrogen air inlet
Pipe, the high pressure nitrogen air inlet pipe is provided with air intake valve.
As preferred embodiment, the high pressure nitrogen air inlet pipe connects high pressure nitrogen tank.
As preferred embodiment, the upper valve, lower valve, air intake valve use electric control valve.
The beneficial effects of the utility model are：By setting valve, lower valve on charge pipe, lower valve is first closed,
Valve is opened again, and loading hopper starts to feed to the inside of charge pipe, is then shut off valve, then opens lower valve, opens simultaneously
Material, is pressed into reactor by the air intake valve of high pressure nitrogen air inlet pipe by the air pressure of inert nitrogen gas, and charging is whole close
Seal gas-tight, it is ensured that production environment cleaning, and workman's are healthy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Reactor 1, loading hopper 2, charge pipe 3, upper valve 4, lower valve 5, high pressure nitrogen air inlet pipe 6, air intake valve

Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of double valve nitrogen pressurization charge pipe, it includes reactor 1, loading hopper 2, charge pipe 3, upper valve
Door 4, lower valve 5, high pressure nitrogen air inlet pipe 6, air intake valve 7, loading hopper 2 are connected by charge pipe 3 with the top of reactor 1, plus
The top of expects pipe 3 is provided with upper valve 4, and the bottom of charge pipe 3 is provided with lower valve 5, the charge pipe 3 between upper valve 4, lower valve 5
High pressure nitrogen air inlet pipe 6 is connected with, high pressure nitrogen air inlet pipe 6 is provided with air intake valve 7.
High pressure nitrogen air inlet pipe 6 connects high pressure nitrogen tank（It is not drawn into figure）.
Upper valve 4, lower valve 5, air intake valve 7 use electric control valve.
By setting valve 4, lower valve 5 on charge pipe 3, lower valve 5 is first closed, then open valve 4, loading hopper
2 start to feed to the inside of charge pipe 3, are then shut off valve 4, then open lower valve 5, while opening high pressure nitrogen air inlet pipe 6
Air intake valve 7, material is pressed into reactor 1 by the air pressure of inert nitrogen gas, the whole sealing gas-tight of charging,
It ensure that production environment is cleaned, and workman's is healthy.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within the utility model will
In the range of asking protection.Scope is claimed by appended claims and its equivalent thereof in the utility model.
