Abstract
The invention discloses an automatic sodium carbonate measuring and conveying device and method in lithium carbonate production. The automatic sodium carbonate measuring and conveying method includes the following steps that sodium carbonate powder is alternatively sent into two vacuum hoppers from a vacuum conveying system; when the material inlet amount of one of the vacuum hoppers reaches the set material adding amount every time, the other vacuum hopper is automatically switched to by the vacuum conveying system to start feeding operation and at the same time, the vacuum hopper finishing feeding starts to perform automatic measuring and discharging and a transition hopper is used for feeding a powder terminal reaction device. Automatic feeding and automatic measuring are alternatively performed by the vacuum hoppers. When the accumulation amount of weighed sodium carbonate powder reaches the total set value, the vacuum conveying system stops working and after the sodium carbonate powder pumped into the vacuum hoppers is discharged, the whole conveying and measuring process is completed. The method has the advantages of being short in procedure, low in energy consumption, free of powder and dust and corrosion and the like.

The present invention can be used for metallurgical and chemical industry, in obtain solution and chemical reaction process, soda ash powder is carried out to accurate measurement and Automatic continuous is carried.
Accompanying drawing explanation
Accompanying drawing is the structural representation of apparatus of the present invention.
The specific embodiment
Referring to accompanying drawing, soda ash automatic gauge and feedway in lithium carbonate production, comprise powder warehouse 1, electronic star-like feeder 2, under storehouse, receiving hopper 3, two vacuum hoppers 6, transition hopper 9, on the bottom discharge mouth of described powder warehouse 1, be provided with successively receiving hopper 3 under described electronic star-like feeder 2 and storehouse, in described vacuum hopper 6, be provided with self-measuring device as weight sensor (not shown), the discharging opening of vacuum hopper 6 bottoms is all connected with described transition hopper 9 by electronic blow-off valve 8, transition hopper 9 can be joined with powder cessation reaction equipment 10, under described storehouse, receiving hopper 3 is connected by delivery duct 4 respectively between the vacuum hopper 6 of vacuum pump and connects and composes vacuum conveying system with each, wherein vacuum hopper 6 is connected with vacuum pump by pipeline 5, in described vacuum hopper 6, be provided with the pulse clearing apparatus 7 and the arch breaking apparatus (not shown) that are connected with air plant.
Electronic star-like feeder, self-measuring device, electronic blow-off valve etc. all adopt prior art.
The inventive method utilizes said apparatus to realize.Particularly, the soda ash powder in powder warehouse 1 is first entered to receiving hopper 3 under storehouse through electronic star-like feeder 2, more alternately send into two vacuum hoppers 6 by vacuum conveying system; Inlet amount in one of them vacuum hopper 6 reaches after each feeding quantity of setting, vacuum conveying system automatically switches to another vacuum hopper 6 and starts feed operation, now, the vacuum hopper 6 that completes charging starts automatic gauges and discharge operation, by transition hopper 9 to powder cessation reaction equipment 10 feed; The Automatic feed of vacuum hopper 6 and automatic gauge blocked operation, when the soda ash powder cumulative amount weighing reaches total setting value, vacuum conveying system quits work, and after being extracted under the soda ash powder row in vacuum hopper 6, completes whole conveying and metering process.
Sodium carbonate powder is obtained by outsourcing conventionally, and is stored in 1 li of powder warehouse.Light ash material granularity is 100-400 order, the about 600Kg/m of bulk density
