Novel chemical powder drying, sorting and packaging production line

Abstract

The invention relates to the technical field of powder production equipment, in particular to a novel chemical powder drying, sorting and packaging production line. The production line comprises a hotblast stove; the hot blast stove is connected with a dryer through a pipe; a feeding inlet of the dryer is provided with a twin-screw feeder; the dryer is connected with a first-stage dust collectorthrough a pipe; the first-stage dust collector is provided with a first-stage feeder; the first-stage feeder communicates with a negative pressure pipeline; the negative pressure pipeline is connectedwith a centrifugal fan through a flange; the centrifugal fan is in flanged joint with a sorting machine; the sorting machine is connected with a second-stage dust collector; a discharge port of the second-stage dust collector is provided with a second-stage feeder; and an automatic weighing packaging machine is arranged under the second-stage feeder. The production line has the beneficial effectsthat the process is novel, the particle size of sorted products ranges from 3 microns to 10 microns, the water content of powder is 0.02% to 0.38%, the sorting efficiency is 97.2%, the product quality is high, full sealed operation is conducted under negative pressure, dust on site is avoided, noise is low, unorganized dust is reduced, the working environment is improved, the product packaging speed is high, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of powder production equipment, in particular to a novel chemical powder drying, sorting and packaging production line. Background technique [0002] At present, the production process of chemical powder is as follows: firstly, the chemical raw materials are processed with a centrifuge or filter press after rinsing to obtain raw materials with a water content of 15%-25%, and then the chemical raw materials with a water content of 15-25% are put into Dry in the dryer, then collect the dried powder with a dust collector, and finally obtain a powder with a water content of less than 0.5%, but the above process not only cannot control the particle size of the product, but also has a high rate of defective products . In the prior art, chemical powders are mainly weighed and packaged manually, which not only has low efficiency and high labor intensity, but also easily causes dust to fly, which is not good for the...

In the prior art, chemical powders are mainly packaged by manual weighing, which not only has low efficiency and high labor intensity, but also easily causes dust to fly, which is harmful to the health of workers
