Centrifugal vacuum defoaming equipment for online continuous treatment

Abstract

The invention relates to centrifugal vacuum defoaming equipment for on-line continuous treatment. The equipment comprises a rack, a feeding pump, a discharging pump, a defoaming disc, a rotating shaft, a power device, a tank body and a transmission system, wherein the tank body and the transmission system are installed on the rack, the feeding pump communicates with the defoaming disc through a feeding pipeline, the defoaming disc is connected with the rotating shaft, the rotating shaft is connected with the power device through the transmission system, the discharging pump communicates with the discharge hole of the tank body, the defoaming disc comprises a surrounding plate, and an annular upper baffle plate, a circular web plate, an annular pressure baffle plate and an annular lower baffle plate which are sequentially connected with the surrounding plate from top to bottom, a crushing baffle ring is arranged on the circular web plate, a crushing membranization cavity, a centrifugal separation cavity, a membranization cavity and a material throwing cavity are formed in the defoaming disc, and a plurality of material throwing holes are formed in the surrounding plate of the material throwing cavity. The defoaming disc used in the equipment is simple in structure and good in defoaming effect, can realize rapid and efficient defoaming of slurry, greatly improves defoaming efficiency, and improves the defoaming consistency of slurry of different batches.

Description

technical field [0001] The invention relates to a degassing device, in particular to a centrifugal vacuum degassing device for online continuous processing of slurry. Background technique [0002] The key part of the defoaming equipment is the defoaming tray. The structure of the defoaming tray commonly used in the factory is as follows: Figure 4 shown. The existing slurry defoaming technology is mainly to cut the slurry by using the small holes on the defoaming plate in a vacuum state, and use the hydraulic impact and the baffle to break and separate the air bubbles in the slurry. The slurry is re-filmed to degas the air bubbles. The main disadvantage of the prior art is that the efficiency is low, and the stability of the defoaming effect of different batches of slurry is insufficient. [0003] Chinese patent application 202110066319.4 discloses a continuous defoaming reciprocating gravity distribution discharge tray, including a tray body, a partition cover and a parti...

AI Technical Summary

Problems solved by technology

This technical solution has the following deficiencies: 1. The slurry flows back and forth from the bottom to the top, and is discharged from the upper part, and the slurry air bubble content after discharge is relatively large; 2. The slurry directly passes through the centrifugal chamber quickly, resulting in The slurry treatment is not thorough, and the slurry direction from bottom to top will leave slurry residue at the bottom of the pan; 3. The structure is more complicated, the cost is high, and the maintenance and repair are relatively difficult
