Abstract

The invention relates to a device and a method for preventing a feeding valve of a ceramic filter from being blocked, which comprises a main pulp pipeline, a distribution barrel, a mixing barrel, the feeding valve and the ceramic filter. Pulp of the main pulp pipeline enters the distribution barrel which distributes the pulp to one or a plurality of mixing barrels, and each mixing barrel is connected with each ceramic filter through a pipeline. The feeding valve is disposed on the pipeline and divides the pipeline into a feeding valve front section pipeline and a feeding valve rear end pipeline. Mineral powder accumulated in the feeding valve, the feeding valve front section pipeline and the feeding valve rear end pipeline is washed and dredged through a backwash device. Due to the fact that after the backwash device and the method are arranged, the blocked valve pipeline of the ceramic filter can be directly washed without stopping other ceramic filters and mixing barrels, production efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the field of pipeline transportation of solid materials, in particular to a device and method for preventing the feed valve of a ceramic filter from being blocked. Background technique

[0002] In the prior art, after the solid material is transported to the terminal station through the pipeline, it enters the distribution tank and two mixing tanks at the top of the plant, and is distributed to 12 ceramic filters through the mixing tank. If a single ceramic filter is shut down for a long time, the feed valve and its nozzle are likely to be blocked, and it is impossible to discharge the material, so all of them need to be shut down to flush the pipeline.

[0003] Such as figure 1 As shown, after the pulp is transported to the terminal dehydration station through the main pulp pipeline 1, it enters the distribution bucket 2 at the upper end of the dehydration workshop, and is distributed to two mixing buckets 3 through the distr...
