Description
Technical field
The utility model relates to the reducing mechanism of the remaining filter cake of a kind of scraper centrifugal machine.
Background technology
Filter residue on bowl wall usually forms abundant bulk due to centrifugal action, and needs between scraper edge and filter bag to retain certain interval in case scratch filter bag, and the simple scraper that uses is difficult to its scraped clean, and the efficiency that scraper is removed is not high yet.More existing band rollers roll the doctor blade device of broken filter cake, although certain fragmentation can be played to filter cake, but the filter residue of wheel bottom part can be pressed on filter bag more securely when roller is blocked up and form some circle skims, roller is crossed Bao Shiyi and is cut bad filter bag, and result of use is not good.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of reducing mechanism that filter cake can be made to know the remaining filter cake of clean scraper centrifugal machine thoroughly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the reducing mechanism of the remaining filter cake of a kind of scraper centrifugal machine, comprise the cylinder body be arranged on scraper support, piston is provided with in cylinder body, piston is provided with push rod, push rod one end passes cylinder body, and push rod flushes with scraper edge position its end when ejecting substantially, part on push rod between inboard wall of cylinder block and piston is arranged with spring, one end away from spring on cylinder body is provided with medium channel, medium channel is connected with delivery hose, delivery hose is provided with the reversal valve controlling delivery hose interval break-make.
As the preferred scheme of one, the import of described medium channel is positioned at just to the position of scraper support, and described scraper support is provided with the sprocket hole be communicated with medium channel, and described delivery hose is connected to sprocket hole place.
As the preferred scheme of one, described piston side is provided with locating slot, and described spring one end is arranged in locating slot.
As the preferred scheme of one, described piston is just provided with locating ring on the surface to medium channel side.
As the preferred scheme of one, the end that described push rod stretches out cylinder body is taper.
The beneficial effects of the utility model are: the reducing mechanism structure of the remaining filter cake of this scraper centrifugal machine is simple, easy to use, Compressed Gas or liquid driven piston driving push rod is adopted to carry out fragmentation to filter cake off and on, filter cake is made to be block protuberance, the adhesion of filter residue on filter bag can not be caused, be convenient to scraper filter cake and remove thoroughly clean.
The import of described medium channel is positioned at just to the position of scraper support, and described scraper support is provided with the sprocket hole be communicated with medium channel, and described delivery hose is connected to sprocket hole place, and delivery hose is connected to inside scraper support, is not easy impaired at work.
Because piston side is provided with locating slot, described spring one end is arranged in locating slot, avoids spring and drives the double swerve of push rod when moving, make the sealing between push rod and cylinder body not fragile, the service life of extension fixture.
Because piston is just provided with locating ring on the surface to medium channel side, piston after retracting completely again air inlet time, gas active area is increased to locating ring inner circle area by gas channel cross-sectional area, relatively easily can promote piston movement.
The end of stretching out cylinder body due to push rod is taper, filter cake fragmentation of being more convenient for.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1. scraper support, 11. sprocket holes, 2. cylinder body, 21. medium channels, 3. piston, 4. push rod, 5. spring, 6. delivery hose, 7. reversal valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, the reducing mechanism of the remaining filter cake of a kind of scraper centrifugal machine, comprise the cylinder body 2 be arranged on scraper support 1, piston 3 is provided with in cylinder body 2, piston 3 is provided with push rod 4, push rod 4 one end passes cylinder body 2, and when push rod 4 ejects, its end flushes substantially with scraper edge position, and push rod 4 end is taper.Part on push rod 4 between cylinder body 2 inwall and piston 3 is arranged with spring 5, piston 3 side is provided with locating slot, and described spring 5 one end is arranged in locating slot.
Cylinder body 2 is provided with medium channel 21 away from one end of spring 5, and medium channel 21 is connected with delivery hose 6, and delivery hose 6 is provided with the reversal valve 7 controlling delivery hose 6 interval break-make.Piston 3 is just provided with locating ring on the surface to medium channel 21 side.The import of medium channel 21 is positioned at just to the position of scraper support 1, and described scraper support 1 is provided with the sprocket hole 11 be communicated with medium channel 21, and described delivery hose 6 is connected to sprocket hole 11 place.
Take medium as gases at high pressure be example, the operation principle of this device is: after scraper tentatively strikes off the filter cake on filter bag, gases at high pressure in delivery hose 6 are by the sprocket hole 11 on scraper support 1, enter cylinder body 2, promote the feed motion of piston 3 and push rod 4, delivery hose 6 controls to supply gas to interval in cylinder body 2 via reversal valve 7 simultaneously, when stopping air feed, piston 3 due to spring 5 elastic force effect drive push rod 4 bounce back, thus realize push rod 4 move back and forth act on remaining filter cake, make remaining filter cake loose, and under the follow-up cutting of scraper, remaining filter cake is made to fall into hopper.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
