Abstract
The utility model discloses a deslagging device used for cleaning the residue on the centrifuge filter screen centrifuge. The structure is that a scraping cutter which is arranged in the a rotating drum is connected with a scraping cutter arm which is connected with a scraping cutter driving device. The utility model is characterized in that the external side of the rotating drum is provided with a gas-blowing apparatus which can blow air to the rotating drum. After the gas-blowing apparatus is arranged, high pressure draught enables the filter screen to generate slight oscillation. Thus, on one hand, the filter cake can be directly blown off the filter screen and on the other hand, the scraping cutter can clean the filter cake thoroughly so that the filter screen can obtain regeneration. The waste of material is reduced and the separating effect and the manufacturing capacity of the centrifuge are enhanced.
Description
Technical field
The utility model relates to centrifuge, refers more particularly to be used for removing in the centrifuge deslagging device of residue on the filter screen.
Background technology
Centrifuge is widely used in the industries such as pharmacy, chemical industry, and its effect is: be mainly used to separate and dry the liquid composition in the material.The primary structure of centrifuge is: damping base, casing is installed on the damping base, be provided with rotary drum in the casing, the top of casing is provided with cover, on the sidewall of rotary drum, offer a lot of through holes, the inwall of rotary drum is provided with filter screen, and rotary drum is driven by drive unit and runs up, and feed arrangement also is installed on cover.During work, the material of need being sloughed the liquid composition by feed arrangement imports in the rotary drum, and the rotary drum of high speed rotating throws away rotary drum with the liquid composition in the material, reaches the purpose of Separation of Solid and Liquid.The liquid composition is separated later material residue (being commonly called as filter cake) will be attached on the filter screen, in order to remove the filter cake on the filter screen, recovered material, in centrifuge, also be provided with deslagging device usually, the structure of traditional deslagging device is: be provided with scraper in rotary drum, scraper is connected with scraper arm, scraper arm with scrape driving device for cutter and be connected; When needs removed the gred work, drive unit drove scraper near filter screen by scraper arm, and scraper is rotated to an angle, and will be removed down attached to the filter cake on the filter screen by scraper.The shortcoming of above-mentioned deslagging device is: owing to always there is the 3-5 mm clearance between scraper and the filter screen, again because the viscosity of material, thereby after the scraper slagging-off, the remaining a lot of filter cakes of past contact meeting on filter screen, usually can only water flushing remain in filter cake on the filter screen with elimination, will cause the waste of material like this; If but non-flushing washing can be stopped up effect and the production capacity that influences the centrifuge Separation of Solid and Liquid because of filter screen again.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of filter screen deslagging device that can thoroughly remove filter cake.
For achieving the above object, the technical solution adopted in the utility model is: the filter screen deslagging device in the described centrifuge mainly comprises: be arranged on the scraper in the rotary drum, scraper is connected with scraper arm, scraper arm with scrape driving device for cutter and be connected; Be characterized in: the air jet system that can blow in rotary drum is arranged in the rotary drum arranged outside.
Above-mentioned air jet system mainly comprises: the gas box, and the gas box is provided with air inlet and air nozzle, and air inlet is fixed on the casing of centrifuge, and air nozzle is facing to the through hole on the rotatory drum wall.
The utility model further technical scheme is: auxiliary air nozzle also is installed on scraper, and auxiliary air nozzle is connected with air inlet pipe by auxiliary gas box.
The utility model has the advantages that: after being provided with air jet system, high pressure draught can make filter screen produce slight vibration, like this, filter screen on the one hand can directly blow off filter cake, help scraper on the other hand more filter cake is thoroughly removed, thereby make filter screen obtain regeneration, not only reduced the waste of material, and improved the separating effect of centrifuge, also improved the production capacity of centrifuge.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
Filter screen deslagging device in the centrifuge described in the utility model, as Fig. 1, shown in Figure 5, mainly comprise: be arranged on the scraper 8 in the rotary drum 2, rotary drum 2 is arranged in the casing 1, the inwall of rotary drum 2 is provided with filter screen 4, scraper 8 is connected with scraper arm 14, scraper arm 14 with scrape driving device for cutter 6 and be connected; The air jet system that can blow in rotary drum 2 is arranged in rotary drum 2 arranged outside.As Fig. 1, Fig. 2, shown in Figure 3, described air jet system mainly comprises: gas box 9, gas box 9 are provided with two air inlets 10 and some air nozzles 11, and air inlet 10 is fixed on the casing 1 of centrifuge, and air nozzle 11 is facing to the through hole on rotary drum 2 sidewalls.In the present embodiment, as Fig. 1, Fig. 4, Fig. 5, shown in Figure 6, auxiliary air nozzle 7 also is installed on scraper 8, auxiliary air nozzle 7 is fixedly mounted on the scraper 8 by fixed block 12, auxiliary air nozzle 7 is connected with air inlet pipe 5 by auxiliary gas box 13, and air inlet pipe 5 is coiled in scrapes on the driving device for cutter 6.
The operation principle of the filter screen deslagging device of said structure is: the slagging-off course of action of scraper 8 is identical with the slagging-off course of action described in the background technology, repeats no more.Its difference is: when needs remove the gred work, in gas box 9, feed the gas of certain pressure by air inlet 10, gas sprays to filter screen 4 by the through hole on air nozzle 11 and rotary drum 2 sidewalls, under the effect of this high pressure draught, filter screen 4 can produce slight vibration, and like this, filter screen 4 on the one hand can directly blow off filter cake 15, help scraper 8 on the other hand more filter cake 15 is thoroughly removed, the process of its slagging-off as shown in Figure 7.After being provided with auxiliary air nozzle 7 on the scraper 8, in scraper 8 slagging-off, gases at high pressure can be ejected on the filter screen 4 by air inlet pipe 5, auxiliary gas box 13 and auxiliary air nozzle 7, can with scraper 8 not the residue of scraping blow and wipe off.From the above mentioned as can be known, use above-mentioned filter screen deslagging device, can make filter screen obtain regeneration better, not only reduced the waste of material, and improved the separating effect and the production capacity of centrifuge.
