Wherein, 1-cylinder, 2-scraper plate, 3-screen cloth, 4-connector, 5-nut, 6-screen frame, 7-bearing pin, 8-flexible pipe; A, B are hose connection; In Fig. 1,2, the direction of arrow is the direction of motion; In Fig. 3, from left to right the model of 3 valves is followed successively by 3A310-08-NC, 4A320-08, S3Y-08.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Water sieve machine automatic scraper of the present utility model, comprises cylinder 1, scraper plate 2, connector 4, nut 5, bearing pin 7, flexible pipe 8;
Cylinder 1 is positioned on the screen cloth 3 of water sieve machine; Connector 4 one end is U-shaped structure, and the other end has screw thread, and the piston rod head of cylinder 1 stretches in the middle of the U-shaped structure of connector 4, and bearing pin 7 passes two straight flanges of piston rod head and U-shaped structure simultaneously, and piston rod can be rotated around bearing pin 7.The end of thread of connector 4 passes the screen frame edge (on the sidewall of screen frame) of water sieve machine screen end, and is fixed on screen frame edge by nut 5.
Two panels scraper plate 2 is arranged on the bottom at cylinder 1 two ends, the end face of two panels scraper plate 2 and the axes normal of cylinder 1, and bottom contact screen cloth 3; Two panels scraper plate 2 plays the support of cylinder 1 and the effect of cleaning screen cloth, and two panels scraper plate 2 can carry out automatic rotation adjustment according to screen cloth 3 surface undulation, to ensure same screen cloth 3 close contact.Scraper plate 2 can be copper.The width (width in the direction vertical with scraper plate 2 direction of motion) of scraper plate 2 is suitable with the width of screen cloth.Two panels scraper plate 2 have several holes, for reducing its resistance of motion in water.
Two flexible pipes 8, respectively as gas intake and exhaust path, are communicated with the inside of cylinder respectively.
During work, cylinder 1 urceolus drives scraper plate to do reciprocating linear motion.Two panels scraper plate 2 scrapes back and forth on screen cloth 3 surface, and the powder blocked in sieve aperture applies external force, makes powder by sieve aperture or the powder of elongate in shape is scraped the particle be broken into as less.Thus reach minimizing sieve pore blockade, the object of cleaning screen cloth.Scraper plate is close to screen surface and is scraped back and forth, clears up the powder be clipped in sieve screen apertures.The powder that scraper plate also can stir loose raft promotes that it is evenly distributed.
This device can also comprise Pneumatic control circuit;
Cylinder is controlled automatically by a set of pneumatic circuit.Cylinder is connected with pneumatic circuit flexible pipe.
Automatic control system is subject to the restriction of worker-house anti-explosion safety, can not adopt conventional electric control system, but adopts the motion of pneumatic circuit to cylinder to control.This control system such as can be arranged in scene or control room at the place of convenient operation.Pneumatic circuit is that 4A320-08,3A310-08-NC, S3Y-08 tri-pneumatic control valves form by model, and annexation as shown in Figure 3.During work, can do to move back and forth continuously by control cylinder.Regulate the stop valve at air inlet and blast pipe place in pneumatic circuit can regulate cylinder moving speed.Closedown stop valve or the switch pulled on S3Y-08 can make cylinder out of service.Cylinder specification is MAL32*200mm, and pipeline specification is 8mm.Pneumatic control circuit does not use stroke valve, makes exterior line very simple, and installation, the dismounting of whole device are all very convenient.
