Description

Novel plate-type closed filter with bottom filter

Technical Field

The utility model relates to a filtration equipment technical field, especially a novel board-like airtight filter of straining at bottom of taking.

Background

The plate-type closed filter is a filtering and adsorbing device used in the industrial production of electroplating, chlor-alkali industry, ceramics, pharmacy, sugar making, wine making, water treatment and the like, and mainly functions to recover and filter solid substances in liquid discharged in production (for example, diatomite impurities in beer production are filtered, and the like, but not always). The plate-type closed filter has the following advantages: the filtering capacity is high, the filtered filter cake can be washed, dried and reused, the cost is saved, and the economic benefit is good; the machine shell is sealed, safe and free of leakage, the environment is clean and free of pollution, and one-time complete filtration can be achieved.

The general structure of the existing plate-type closed filter comprises a tank body, a hollow filter plate, a drain valve, a water pump and other parts. The during operation, the water pump will need filterable sewage to take out in the sewage jar, then the pump is gone into jar internally, sewage through a plurality of filter outside micropores that parallel in jar internal upper end get into the filter, again from with a plurality of filters in the communicating clear solution pipe flow of lower extreme get into the clear solution jar, open the lower extreme blowoff valve discharge of jar body after the filtration finishes and be located jar internal lower extreme and do not have filterable clear solution to and the adhesion is at the solid matter impurity of filter outside end. After the existing plate-type closed filter stops working, liquid below the filter plate at the lower end in the tank body is not filtered, so that the unfiltered liquid is directly discharged into the sewage tank for secondary filtration, and the work efficiency is not improved. In addition, because fixed object impurities are continuously adhered to the outer side of the filter plate in the filtering process, the existing plate type closed filter cannot remove the fixed object impurities, and therefore the filtering effect of the plate type closed filter is influenced. Based on the above, the filter plate type closed filter with the bottom is provided, which not only can effectively filter impurities in liquid at the lower end in the tank body after shutdown, but also can remove impurities outside the filter plate during filtering as much as possible, and ensures the filtering effect.

SUMMERY OF THE UTILITY MODEL
