Description

Technical Field

[0001] The utility model belongs to the field of sugar production equipment, and specifically relates to a neutralized juice sedimentation device. Background Art

[0002] In the sugar-making process of existing sugar-making enterprises, flocculants need to be added to help the neutralized juice to precipitate. Generally, the neutralized juice is first placed in a steam dissipation device to fully dissipate steam and remove bubbles. After the steam is dispersed, the neutralized juice is added with flocculants and placed in a settler to precipitate to release clear juice. Whether the flocculant and the neutralized juice are fully mixed directly affects the precipitation effect and the time required for precipitation. There are two existing methods for adding flocculants to the neutralized juice: the first is to set a flocculant addition port before the juice inlet of the settler, and directly add the flocculant without a mixing device; the second is to install a stirrer before the juice inlet, and the flocculant addition port is set in front of the stirrer, and the stirrer is used to mix the flocculant and the neutralized juice evenly.

[0003] Patent No. CN200720048895.1 discloses a settler with an automatic mixing device, which provides a settler with an automatic mixing device that can completely mix the flocculant with the neutralizing juice, quickly settle the mixed liquid, reduce the amount of mud juice, reduce the loss of sucrose conversion, improve product quality, and save the amount of flocculant. The automatic mixing device that can fully mix the neutralizing juice and the flocculant is provided at the input end of the settler. The automatic mixing device includes a mixer body, which is composed of a shell and a baffle arranged inside the shell to change the flow direction of the liquid. After the neutralizing juice and the flocculant are fully mixed, floccules will be produced. The floccules with a lighter texture float and are not easy to settle, which will affect the sedimentation effect. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, the utility model discloses a neutralization juice sedimentation device, wherein the neutralization juice heater of the neutralization juice sedimentation device is connected with a first steam dispersion box and a second steam dispersion box, and the neutralization juice enters the flocculant box and is mixed with the flocculant after two steam dispersions, and after the neutralization juice is added to the flocculant box, the flocculant is added from the flocculant inlet pipe and mixed with the neutralization juice in the flocculant box, and the mixture is stirred and mixed by a first stirring blade, and during the stirring process, the air pump takes in air and sprays it from the nozzle, and the bubbles carry the flocculants with a lighter texture.
