Description
Technical field
The present invention relates to filter field, specifically, relate to a kind of negative-pressure cyclic band filter.
Background technology
Conventional negative pressure filter adopts filter paper to use as independent filtering material, but there are certain risk factors in the independent use procedure of filter paper, therefore impact is existed on the stable operation of system, such as: 1. in filter paper use procedure because of damaged leak that filter paper sole mass problem exists; 2. filter paper is selected unreasonable, and tensile strength is not enough; 3. fail and alarm without paper alarm failure, do not change the situations such as filter paper in time.These all can cause the soiling solution in soiling solution chamber directly to enter clean liquid case, cause clean liquid to pollute, and damage water pump, user's machine tool chief axis, cutter, cause workpiece to be machined to scrap.
Because adopting filter paper as filter material in the use procedure of existing negative pressure filtration machine, therefore for there being the filter plant of consumptive material, need in user's use procedure to carry out filter material replacing according to actual beat.
Summary of the invention
The invention provides a kind of negative-pressure cyclic band filter, technical problem to be solved is tradition.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
The invention provides a kind of negative-pressure cyclic band filter, comprise housing, top in described housing is provided with dirty liquid cavity, bottom in described housing is provided with clean sap cavity body, negative pressure cavity sense switch is provided with in described clean sap cavity body, described hull outside is provided with clean liquid suction pump and fluid infusion system pipeline, described clean liquid suction pump is connected with clean sap cavity body with fluid infusion system pipeline, it is characterized in that, also comprise be arranged on enclosure interior scrape bits plate, scraper plate drive motors and enclosed endless filter belt, the bottom of described housing is fixedly connected with multiple limiting roll, described endless filter belt is set in the outside of limiting roll, the inner side of described endless filter belt is provided with endless filter belt and opens device and deadweight idler roller, described endless filter belt opens device and deadweight idler roller lays respectively at the both sides of endless filter belt, described scraper plate drive motors is fixedly installed on enclosure interior and considers plate to be worth doing and be electrically connected with scraping, described in scrape the outside that bits plate is arranged on endless filter belt.
Preferably, described housing is also fixedly connected with endless filter belt cleaning device, the inner side that described endless filter belt cleaning device is positioned at endless filter belt is connected with housing, and the position that the outside of described endless filter belt is corresponding with described endless filter belt cleaning device is provided with feeder.
Preferably, also comprise rapping apparatus, described rapping apparatus is arranged on the inner side of endless filter belt, and described rapping apparatus is fixedly connected on housing.
Preferably, in described dirty liquid cavity, be provided with dirty liquid chamber liquid level detecting switch, in order to detect the liquid level of dirty liquid intracavity liquid.
Preferably, the bottom of described housing is provided with endless filter belt liquid dish, collects in order to the dirty liquid produced by clean cycle filter bag, avoids causing secondary pollution to environment.
Preferably, described housing is provided with filter paper volume, the filter paper of described filter paper volume can together with endless filter belt filter liquor.
The invention has the beneficial effects as follows: negative-pressure cyclic band filter of the present invention uses easier, structure is more reasonable, effectively can save waste that is artificial and resource, obtain more clean free of contamination filtrate, wherein, adopt endless filter belt as basic filter material, can filter with existing filter paper overlaid simultaneously, form a kind of safer filter, avoid being used alone filter paper to occur as the accident existed in filter material process, by the mode that superposition is filtered, can improve the filtering accuracy of existing independent filter paper, be one filter safely and efficiently.And because endless filter belt reciprocally uses, Operation system setting endless filter belt cleaning device, therefore endless filter belt can maintain clean liquid throughput and filtering accuracy efficiently always, avoids filter paper regular in user's use procedure and changes installation, realizes no material consumption and filters; By arranging rapping apparatus at exfoliation end, the closely knit chip being adsorbed in circulating filtration belt surface being relaxed, being easy to be scraped bits plate and peeling off; Rely on the deadweight of deadweight idler roller, in the vertical direction falls downward vertically, and endless filter belt is carried out tensioning, in use can follow the stretching change of endless filter belt, constant tension endless filter belt, avoids in use procedure due to fault that circulating filtration belt sag causes; When endless filter belt carries out overhauling or changing, only deadweight idler roller need be packed up and be positioned over a high position, easily endless filter belt interface can be opened and carry out maintenance replacing.When endless filter belt independently uses, endless filter belt detergent line is cleaned endless filter belt, endless filter belt arranges feeder below cleaning area, the soiling solution washed down is collected, be delivered to filter soiling solution cavity, carry out recirculation to filter, avoid the soiling solution washed down to carry out secondary pollution to clean liquid water tank.
