Description
Technical field
The utility model relates to a kind of vacuum ceramic filter plate that is used for ceramic filter, belong to ceramic filter attachment technique field.
Background technology
Filter is to utilize the porous filter medium, holds back the solid particle in liquid and the solid particle mixture, and realizes the equipment that solid, liquid separates.Filter is widely used in departments such as chemical industry, oil, pharmacy, light industry, food, ore dressing, coal and water treatment.Filter is the core component of ceramic filter.Adopt inorganic fenestra burning process, utilize capillary theory, form vacuum in the plate, extract the energy-conservation effectively moisture content in the slurry separation, and the solid matter in the slurry is trapped on the filter, strikes off with scraper again.The international standard and the national sector standard that also do not have at present filter, the domestic industry standard that filter is only arranged, the quality of coming the standard filter.And the theoretical research aspect of designing and developing of filter relatively lags behind, and makes the performance of filter and practical effect be difficult to satisfy the more and more higher requirement of client, such as: the result of use of filter and service life.Many employings formula filtering technique in the mine ore dressing technology in the past because this process energy consumption is big, yields poorly, and water resource runs off big, and mine tailing moisture is big, takes up an area of extensively, and has caused and deposited potential safety hazard.
Summary of the invention
The utility model proposes a kind of vacuum ceramic filter plate that is used for ceramic filter, its purpose is intended to guarantee that filter continue to keep solid-liquid separation capability in its whole life cycle, increases backwash as much as possible and ultrasonic combined Chemical cleaning pressure promotes the filter cleaning performance.
Technical solution of the present utility model: it is characterized in that on face, having fenestra, the fenestra shape is the step shape, be back taper, face thickness 0.2-0.7mm, the fenestra shape is gross porosity type or middle diplodal or pore type or ultra-fine pass, establish water nozzle on the base of vacuum ceramic filter plate, the assembling circle is established in the bottom of vacuum ceramic filter plate, vacuum ceramic filter plate outer arc chord length 382-610mm, vacuum ceramic filter plate base 228-302mm, the centre-to-centre spacing 166-239mm of two assembling circles, assembling circle external diameter 38-50mm, assembling circle internal diameter 11-14mm, water nozzle external diameter 14-19mm, vacuum ceramic filter plate vertical height 316-619mm, assembling circle centre-to-centre spacing base height 34.5-37mm, vacuum ceramic filter plate thickness 25-35mm;
Advantage of the present utility model: the buying expenses of having saved the user; Reduce the frequency of changing filter, reduced unexpected plate bursting in producing and loss downtime that causes, improved production efficiency; Reduce solid useless generation in the production process, the good value of environmental protection and economic results in society are arranged.Selected the inorganic material that improves the face abrasion resistance for use, made the performance of filter be greatly improved, overall construction intensity (hygrometric state) reaches the 0.6MPa pneumatics and tests not plate bursting, and abrasion resistance exceeds conventional face more than one times.For the better The field of users lays a solid foundation.Owing to greatly improved the service life of filter, make the scrappage of filter descend at least more than 50%, reduced solid useless generation, further alleviated environmental protection pressure, have popularizing application prospect preferably.
