Description
Technical Field
[0001] The utility model relates to the technical field of moisture discharge, in particular to a dusty moisture exhaust anti-blocking device. Background Art
[0002] At present, with the popularity of new energy vehicles, the demand for basic lithium salts has also increased. Basic lithium salts include lithium carbonate and lithium hydroxide monohydrate, which are widely used basic lithium salt products. Basic lithium salts generally need to go through unit operations such as chemical reaction → centrifugal separation → drying to obtain products with low water content. Among them, the drying process is a very important process.
[0003] The traditional drying process of basic lithium salts is to use disc dryers, fluidized beds, electric kilns and other equipment for drying. During the drying process, an induced draft fan is required to continuously discharge the moisture generated during the drying process. In the actual production process of this process, in order to ensure the continuity of the drying process, the drying equipment generally maintains a negative pressure between -1.2 and -0.2 kPa through an induced draft fan. Under this working condition, when the dust-containing moisture is discharged, the powdered material is inevitably taken away. When the dust-containing moisture condenses and the pipeline resistance increases, it will cause dust to settle and accumulate in the exhaust pipe, causing the drying process to fail due to the inability to discharge moisture, and at the same time causing material loss. When cleaning the blocked exhaust pipe, it is necessary to shut down the machine and arrange a large amount of manpower to dismantle the pipe for cleaning, which not only affects continuous production, but also increases safety hazards.

A flushing pipe is installed on the first exhaust pipe.
[0006] Flushing water is injected into the first exhaust duct through the flushing pipe, so that the flushing water is mixed with the dust-containing moisture in the first exhaust duct and flows into the liquid storage barrel, the solid particles settle in the liquid in the liquid storage barrel, and the exhaust gas is discharged to the dust collection system through the second exhaust duct.
[0007] As a further optimized solution of the utility model, the first exhaust duct has an inclined portion, and an end of the inclined portion close to the liquid storage barrel is a downward bottom end.

[0009] As a further optimized solution of the utility model, a liquid drain pipe is installed at the bottom of one end of the second air drain pipe close to the exhaust port of the liquid storage barrel.
[0010] As a further optimized solution of the utility model, an observation mirror is installed on the first exhaust duct.
[0011] As a further optimized solution of the utility model, the exhaust port of the liquid storage barrel is arranged on the side of the liquid storage barrel, and the exhaust port is higher than the liquid level in the liquid storage barrel.
