Problems solved by technology

After a large amount of fine-grained slurry enters the ceramic filter, it will cause problems such as clogging of the pores of the ceramic filter plate and a decrease in cleaning effect, causing the output of the ceramic filter to be less than the ore delivery volume of the pipeline, and this clogging requires a longer cleaning period or replacement of ceramics The filter plate can only be restored, which has a great impact on later production and cost

Embodiment Construction

[0030] Combine below Figure 1-4 , the present invention will be further described.

[0031] figure 2 Show the ceramic filter dehydration system provided by the present invention, in figure 1 Based on the prior art shown, the figure 2 In addition, a sewage pipeline connected to the accident pool 6 from the sewage pump 9 in the bottom flow pump room 12 is used for the overflow water of the concentration pool 1 to enter the accident pool 6 for precipitation. A new slurry pump 10 and an accident pool slurry pipe 14 are added after the accident pool 6 to connect the accident pool to the overflow pipe 5, which is used to stir the fine-grained ore deposited in the accident pool with water to the concentration pool 1 during the maintenance period, and then re-enter Dehydration workshop 11 is dehydrated.

[0032] image 3 Shown in is the production process when the slurry properties are normal. After the pulp reaches the terminal dehydration station, it directly enters the dis...

Abstract

The invention discloses a ceramic filtering machine dehydrating system and a dehydration technique thereof. The system comprises a distribution barrel (3), a ceramic filtering machine (4), a concentration basin (1), an accident basin (6), a base flow pump (2) and an overflow pipe (5). The distribution barrel (3) is connected to an ore pulp pipeline through a distribution valve (7) for distributing the ore pulp to the ceramic filtering machine (4), and the overflow pipe (5) is connected with the ceramic filtering machine (4) and the concentration basin (1) for conveying the ore pulp and cleaning water overflowing from the ceramic filtering machine (4) to the concentration basin (1) to precipitate. The invention is characterized in that a pipeline is provided to connect the ore pulp pipeline and the concentration basin, and the pipeline is controlled by a concentration valve (10) and is used for concentrating the ore pulp in the concentration basin and then distributing the ore pulp to the ceramic filtering machine for carrying out solid-liquid separation. The invention can avoid mass blockage of a ceramic filtering plate and improve capacity of the ceramic filtering machine.

Description

technical field [0001] The invention belongs to the field of pipeline transportation and relates to a pulp dehydration process, in particular to a ceramic filter dehydration system and a ceramic filter dehydration process method for improving the productivity of the ceramic filter. Background technique [0002] Ceramic filter is a new type of high-efficiency and energy-saving solid-liquid separation equipment. It integrates microporous ceramics, mechanical manufacturing, ultrasonic cleaning, and microcomputer control. It uses microporous ceramics as the filter medium and applies the principle of capillary effect for solid-liquid separation. [0003] When the pipeline is normally transported, there are a small amount of free iron ions, ferrous hydroxide, ferric oxide and other iron compounds in the iron concentrate slurry. With the process change of the dressing plant, the content of this part of the compound is increasing. figure 1 discloses the existing production process ...
