Full automatic pressure filter scrape mud and filter cloth cleaning device automatically
The utility model relates to a kind of filter press, and what especially relate to a kind of filter press scrapes mud and filter cloth cleaning device automatically.
Filter press is mainly used in the sewage disposal in mine, metallurgy, chemical industry, electron trade and the environment-friendly engineering, is a kind of application solid-liquid separating equipment very widely.Some operation of the filter press of prior art also relies on manual finishing, following bricklayer's preface, and what have still continues to use handwork, and the concussion of employing mud is down also arranged, and concussion mud down exists down the unclean problem of mud, and it is bigger to shake noise.
Summary of the invention
The utility model main purpose is: for the deficiency that overcomes on the above-mentioned prior art provides a kind of mud-scraping apparatus and corresponding filter cloth cleaning device that adopts atmospheric control and PLC technology.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: have mud-scraping apparatus, cleaning device and atmospheric control, water system, electric control system, it is characterized in that, mud-scraping apparatus is: have two pairs of guide pillars that are installed in symmetric arrangement on the device, connecting plate is arranged below every pair of guide pillar, be connected with symmetric arrangement and scraper plate that can convergent-divergent below the connecting plate; Be provided with cylinder in the middle of the guide pillar of described symmetric arrangement, cylinder and guide pin bushing are fixed on the base plate, and cylinder piston rod is connected with connecting plate; Described scraper plate joins by scraper plate railway carriage or compartment and connecting plate, and links to each other with cylinder.
Filter cloth cleaning device is: press water links to each other with sparge pipe under being installed in every pair of guide pillar by tube connector, and a plurality of water spouts are housed on the sparge pipe.
Technique scheme of the present utility model can also be further perfect, and as preferably, described device adopts four wheels to be installed on the track girder at filter press top.
As preferably, described device links to each other with chain, and the sprocket wheel that matches with it is driven by the drive motors after slowing down.
The beneficial effects of the utility model are: owing to created the brand-new mud system of scraping, adopted pneumatic, hydraulic pressure and PLC technology, have reasonable in design, reliable in structure, the production efficiency height, it is clean to scrape mud, uses characteristics such as very convenient.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as Fig. 1-shown in Figure 4, mud-scraping apparatus is: two pairs of guide pillars 1 that are installed in symmetric arrangement on the device, be provided with cylinder 2 in the middle of the guide pillar, cylinder 2 is fixed on the base plate 18 jointly with guide pin bushing 17, be connected with connecting plate 4 between every pair of guide pillar 1 lower surface, the scraper plate railway carriage or compartment 5 of symmetric arrangement is arranged on the connecting plate 4, scraper plate 6 is arranged in the scraper plate railway carriage or compartment 5, scraper plate 6 links to each other with cylinder 7.Filter cloth cleaning device is: press water links to each other with sparge pipe 8 under being installed in every pair of guide pillar 1 by tube connector, and a plurality of water spouts 9 are housed on the sparge pipe 8.Whole device is installed on the track girder 10 at filter press top with four wheels 3, and reaches chain 11 drivings that are connected with dolly with drive motors 15 by sprocket wheel 12, and described motor slows down through frequency converter frequency conversion and decelerator 16.The atmospheric control of present embodiment is: control two cylinders 2 respectively by two two-position five-way electromagnetic gas valves, to implement moving up and down of scraper plate railway carriage or compartment 5, with two cylinders 7 of two two-position three way electromagnetic gas valve control, open and shrink to implement scraper plate 6.The water system of present embodiment is: be made up of water tank, centrifugal pump, bi-bit bi-pass normally closed solenoid valve, aciculiform pressure regulator valve and two jet pipes 8 that a plurality of nozzles 9 are housed; When magnetic valve cuts off the power supply (normally closed), start water pump, regulate the aciculiform pressure regulator valve water pump is worked under certain pressure, at this moment, the liquid of pump output is by aciculiform pressure regulator valve reflow tank, when needing to clean filter cloth, magnetic valve gets electric, and water under high pressure enters jet pipe by magnetic valve filter cloth is carried out washing and cleaning operation.Present embodiment adopts programmable controller (PLC) technology, and configuration pressure transmitter, liquid level sensor, near sensing elements such as switch, time controllers, realize scraping the automatic control of mud and filter cloth matting.The utility model is applicable to using on various plate and frames, van-type and the press type filter press.
