Problems solved by technology

[0011] The technical problem to be solved by the present invention is: aiming at the situation that the moisture content of the minerals after the dehydration of the current dehydrator is still high, the equipment is super large, the energy consumption is high, and the efficiency is low, a dehydrator with strong adaptability, good dehydration effect, and occupying an area is proposed. Small space, continuous production of low-cost, high-efficiency and energy-saving ultra-fine mineral processing and dehydration equipment

Embodiment 1

[0031] like figure 1 As shown, the dehydrator includes a casing 3 , a material inlet 1 , a spiral scraper 5 , a screen 4 and a centrifuge outlet 6 . The centrifugal dehydrator is a vertical dehydrator, the feed inlet 1 is above the dehydrator, the screen 4 and the spiral scraper 5 rotate around the vertical direction, and the ore slurry or coal slurry is poured into the feed inlet 1 from above the dehydrator. After dehydration, it will be discharged from the bottom of the dehydrator.

[0032] After the ore slurry or coal slurry is poured into the feed port 1, the ore slurry or coal slurry will be transferred to the rotating screen 4, and the screen 4 can be rotated after starting the motor, so that the ore slurry or coal slurry in the screen 4 will be processed Centrifuge to dehydrate. The dehydrated ore slurry or coal slurry is discharged from the outlet, and the water in the ore slurry or coal slurry will enter the centrifuge outlet 6 through the screen 4 under the action ...

Embodiment 2

[0039] like figure 2As shown, the difference from Embodiment 1 is that the centrifugal dehydrator in this embodiment is a horizontal dehydrator, the feed inlet 1 is on one side of the dehydrator, and the screen 4 and the spiral scraper 5 are all rotated in the horizontal direction. , The ore slurry or coal slurry is poured into the feed port 1 from one side of the dehydrator, and will be removed from the other side of the dehydrator after dehydration.

[0040] In addition, in this embodiment, the position and structure of components such as the centrifugal liquid outlet 6, the conduit 7, and the spiral scraper 5 are also different from the first embodiment, but the principle and method of vacuuming and enhancing the dehydration effect are similar.

Abstract

The invention discloses a dehydration method and device of a vacuum filtration centrifugal dehydrator. The dehydrator comprises a shell, a feed port, a conveying device, a spiral scraper, a screen and a centrifugate outlet; a vacuumizing device is arranged on the dehydrator, and is connected with the centrifugate outlet; and a sealing device is arranged in the dehydrator for sealing the dehydrator. The conveying device is used for conveying raw materials to be dehydrated into the rotating screen for centrifugal dehydration; and the dehydrator is vacuumized by the vacuumizing device while centrifugal dehydration is performed. The vacuum negative-pressure dehydration, the centrifugal dehydration and the reduction of an interception particle size through adjustment of gaps of the screen are combined to improve the vacuumizing and dehydrating effects and to reduce the loss of fine particle pulp or coal slurry; and the dehydration of fine particle raw materials on the centrifugal dehydrator is realized.

Description

technical field [0001] The invention relates to a filter centrifugal dehydrator, in particular to a centrifugal dehydrator with a vacuum device. Background technique [0002] In mineral processing and other industries, a large amount of fine ore powder is produced through crushing and grinding of minerals, and a large amount of ore pulp is produced through dense medium and flotation processes, so the ore pulp needs to be dehydrated. [0003] The invention relates to a terminal dehydrator used for flotation of clean coal, medium coal, tailing coal, primary coal slime, cyclone underflow and pipeline transportation coal. At present, domestic coal preparation plants mostly adopt two methods when dealing with fine coal slime of 0.005~1.3mm, instead of using centrifugal dehydrator: [0004] 1. Vacuum filter. Although the machine has high filtration strength, the water content of the filter cake is poor, the quality of the filtrate is not high, the price is expensive, the structu...
