Description

Catalyst tank for producing soft foam polyether

Technical Field

The utility model relates to a soft bubble polyether technical field especially relates to a catalyst jar is used in soft bubble polyether production.

Background

Polyether polyol (polyether for short) is prepared by the polyaddition reaction of an initiator (a compound containing an active hydrogen group) and Ethylene Oxide (EO), propylene oxide (P0), Butylene Oxide (BO) and the like in the presence of a catalyst, the largest polyether yield is that glycerol (glycerol) is used as the initiator and epoxide, various general polyether polyols are produced by changing the conditions of the feeding modes (mixed addition or separated addition), the feeding ratio, the feeding sequence and the like of P0 and E0, the feeding speed of the catalyst cannot be controlled by the feeding hopper of the existing catalyst tank for producing the soft foam polyether polyol, and the reaction speed cannot be controlled by the large amount of the catalyst entering the catalyst tank.

Therefore, how to design a catalyst tank for producing the soft foam polyether becomes a problem to be solved currently.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a catalyst tank for producing soft bubble polyether.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a catalyst jar is used in soft bubble polyether production, includes a jar body, the upper end fixedly connected with apron of the jar body, the lower extreme of the jar body is connected with the discharging pipe, install the solenoid valve on the discharging pipe, it has the annular gasbag of circle to go back fixed mounting on the inner wall of discharging pipe, the gasbag is located the top of solenoid valve, the one end of gasbag is connected with the compressed air storage tank through the intake pipe, the other end of gasbag is connected with the blast pipe, all install the pneumatic valve on intake pipe and the blast pipe.

Preferably, the upper end face of the airbag is obliquely arranged.

Preferably, the lower end of the inner wall of the discharge pipe is embedded with a pressure sensor.

Preferably, a single chip microcomputer is installed on the outer wall of the discharge pipe, and the single chip microcomputer is electrically connected with the pressure sensor and the pneumatic valve respectively.

Preferably, a window is arranged on the side wall of the tank body.

The utility model has the advantages that: when the device uses, with the lower extreme and the retort be sealing connection of discharging pipe earlier, open the solenoid valve, can add the retort with the internal catalyst of jar, when retort pressure is big, pressure sensor detects pressure big, pneumatic valve in the singlechip control intake pipe is opened this moment, aerify to the gasbag, the gasbag inflation this moment, the internal diameter of gasbag diminishes, the catalyst speed of dropping is slow, when retort pressure is little, pressure sensor detects pressure little, the pneumatic valve on the singlechip control blast pipe is opened this moment, the gasbag exhausts, the gasbag reduces this moment, the internal diameter grow of gasbag, the catalyst speed of dropping is fast, this device can be according to the interpolation speed of retort internal pressure automatically regulated catalyst, high durability and convenient use, can effectual improvement production efficiency.
