Embodiment Construction

[0014] Attached below figure 1 Describe the working process of the ceramic filter.

[0015] a. When the work starts, the ceramic filter plate 3 submerged in the slurry tank 5 forms a thick particle accumulation layer on the surface of the ceramic filter plate 3 under the action of vacuum, and the filtrate passes through the ceramic filter plate to the distribution head to reach the filter bucket6. The filtrate in the filter bucket 6 is discharged to the filtrate pool through the height difference.

[0016] b. In the drying zone, the filter cake 4 continues to be dehydrated under vacuum.

[0017] c. After the filter cake 4 is dried, it is scraped off by a scraper in the unloading area and transported to the required place by a belt conveyor.

[0018] d. The unloaded ceramic filter plate 3 finally enters the backwashing area, and the filtrate water enters the ceramic filter plate 3 through the distribution head, and the ceramic filter plate 3 is backwashed, and the particles ...

Abstract

The invention discloses a method for enhancing filtration coefficients of ceramic filters, comprising the following steps: setting the liquid level parameter of a tank body of a ceramic filter; keeping a liquid level in an overflow state; overflowing mine pulp with low concentration continuously from the tank body; leading the overflowed mine pulp with low concentration into a thickening pool forconcentration; leading the concentrated mine pulp with high concentration into the tank body of the ceramic filter; forming a circulating system with low-concentration overflowing and high-concentration entry; and washing the ceramic filter once every 7 working hours, with the washing time of 1 hour each time. The method can enhance the filtration coefficient of the ceramic filter to more than 0.8 from 0.6 to 0.7.

Description

technical field [0001] The invention belongs to the field of long-distance pipeline transportation of ore slurry, in particular relates to the slurry-solid-liquid separation therein, and specifically relates to a process method for improving the filtration coefficient of a ceramic filter. Background technique [0002] In order to facilitate the transportation of ore, the ore is ground into a certain fineness of ore powder before transportation, and then mixed with water and other chemical solvents to form a slurry. When the pulp is transported to the destination, it is necessary to remove the water in the pulp, that is, to separate the mineral water; the basic function of the ceramic filter is to remove the water in the pulp to obtain a concentrate powder with a water content of about 9%. The filtration coefficient of the ceramic filter is related to factors such as pulp concentration, pulp characteristics, and ceramic plates. The filtration coefficient is generally around 0...
