20150209804 | CENTRIFUGAL SEPARATION DEVICE - The present invention relates to a centrifugal separating apparatus for separating fine particles of different densities in slurry. The existing sorting principle of the centrifugal separation apparatus for sorting the fine slurry in terms of specific weight thereof is to utilize the inertia of the slurry flowing with the rotation of a centrifugal drum, so as to keep an appropriate relative movement between the slurry and the drum, thereby producing a laminar flow with a speed gradient. The purpose of sorting in terms of specific weight thereof can be achieved by using the Bagnold's Effect produced in the laminar flow. The disadvantage of the device is that it is not easy to control the speed gradient of the relative movement of the slurry, thereby affecting an effect of separation. The present invention discloses a centrifugal device, which applies a power activation with a controllable strength onto the slurry materials in a centrifugal force field by means of a mechanical activation device, and enables the slurry materials to produce a laminar flow with an appropriate speed gradient relative to the centrifugal device, thereby promoting the Bagnold's Effect and achieving the purpose of precisely sorting. | 07-30-2015 |

20130072369 | CENTRIFUGAL SEPARATOR - A centrifugal separator includes a separation drum, a feed inlet, at least one heavy material outlet with a ring-shaped recess and at least one light material outlet. The feed inlet is located at the head of the separation drum. A feed accelerator is installed at the feed inlet. This feed accelerator cooperates with the proper form of the separation drum and the corresponding location of the material outlet to form a material differential rotation propulsion device. The material differential rotation propulsion device is capable of rotating the feed slurry material along with the separation drum in a slightly different rotation speed and forcing the processed materials to be discharged from separation drum via different outlets. The infeed flow rate is larger than or equal to the total sum of the outfeed flow rates of heavy and light materials so that the separation drum is full of materials during operation. | 03-21-2013 |
20130061516 | PREPARATION METHOD FOR ULTRA LOW ASH COAL-WATER SLURRY - A method for preparing ultra-low ash coal-water slurry includes: (A) grinding of coal to a size below the upper size limit and then making a proper concentration slurry; (B) screening coal by using the slurry particle separation device and separating them by density into tailings, middlings and clean coal, adjusting the fraction of clean coal production according to the ash content standard of final product and then producing the clean coal slurry and tailings slurry; (C) wet grinding of the middlings in step B; (D) reprocessing the product in step C by step B. The upper size limit can be 0.2 mm, 0.01 mm or 0.001 mm, and the ash content can be below 2%, 1% or 0.5%. This method can largely enhance the production rate of clean coal, improve the coal-water slurry fuel's particle size graduation, improve the fluidity and increase the particle concentration of the coal-water slurry fuel. | 03-14-2013 |
