A flap limit water scraper device for belt filter press

Abstract

The invention discloses a novel flip limiting type water containing scraping knife. The novel flip limiting type water containing scraping knife has the advantages that by utilizing the self ascending and descending of press filter equipment, the scraping knife is automatically turned; by arranging a limiting sheet on a screw rod, the scraping knife is rotated and positioned, so as to scrape remained material on filter cloth at different angles; the possibility of deflection of the filter cloth and the leakage of filter liquid on containing equipment are reduced, the water content of a filter cake is reduced, and the double functions of material scraping and water containing of the scraping knife are realized; the scraping knife is made of a common material, the processing is convenient, the structure is compact, the maintenance and replacement are easy, the electrical control is not needed, and the manufacturing cost of a production factory and the use cost of a use factory are reduced.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a flap-limiting water-receiving scraper device for belt-type filter presses. Background technique [0002] The vertical filter press is a fully walking filter cloth filter equipment. The filter cloth acts as a filter medium in the filtration stage, and also has the function of conveying filter cakes in the unloading stage, and conveys the filter cakes to the hoppers at the front and rear ends respectively. When filtering and unloading the cake and washing the cloth, the seeping filtrate and washing water will flow into the hopper along the guide rollers at both ends of the filter press, resulting in a high moisture content of the filter cake and a decrease in product quality. When filtering special materials such as 4A zeolite, dye intermediates, etc., the filtrate and washing water falling into the hopper will directly change the physical and chemical properties of the fi...

Problems solved by technology

When filtering and unloading the cake to wash the cloth, the seeping filtrate and washing water will flow into the hopper along the guide rollers at both ends of the filter press, resulting in a high moisture content of the filter cake and a decrease in product quality

When filtering special materials such as 4A zeolite, dye intermediates, etc., the filtrate and washing water falling into the hopper will directly change the physical and chemical properties of the filter cake, resulting in poor product stability, and even defective and waste products, bringing economic benefits to the manufacturer. loss

[0003] Up to now, many filter press manufacturers at home and abroad have not found an effective way to solve the above problems
