Description

Full-automatic suspended centrifuge scraper discharging device

Technical field

The utility model relates to full-automatic suspended centrifuge, designs the scraper discharging device of the full-automatic suspended centrifuge of a kind of novel cylindrical rotary drum especially.

Background technology

Full-automatic suspended centrifuge is a kind of rotary drum to be suspended on perforated wall centrifuge on the bracket supporting seat by the main shaft upper end, machine is by circuit, gas circuit, mechanically combining Automatic Control, under full-automatic programme-control, separated suspension material is injected in the rotary drum, when rotating at a high speed, utilize centrifugal force field effect liquid is discharged outside the rotary drum, the filter screen that solid particle then is laid in the rotary drum dams, and finishes solid and fluid separation applications.At present, the drum structure of suspended centrifuge has two kinds, and a kind of is conical structure, and another kind is a cylindrical structural.Its discharge way of the rotary drum of conical structure has three kinds: first kind is manual cleaning's mode, and second kind is the gravity self-tipping type, and the third is mechanical scraper formula.Its discharge way of the rotary drum of cylindrical structural scrapes material from drum inner wall by the radial and axial motion of mechanical type scraper, present existing doctor blade device, be to lean on the promotion of a cover hydraulic system or pneumatic system to realize scraping about the cutter hub and the action of rotation, owing to be not provided with protection interlocking positioner, easily cause scrape cutter hub cut off the power supply suddenly or the snap action of dying malfunctioning and cause mechanical breakdown.

The utility model content

A technical problem to be solved in the utility model is: a kind of novel structure is provided, can regulates, machining accuracy height, automation control and be provided with the scraper discharging device of the full-automatic suspended centrifuge of protection interlocking positioner.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the mechanical type scraper discharging device of full-automatic suspended centrifuge, comprise: be arranged on the guide rail pillar on the centrifuge machine seat surface plate, be arranged on the lift cylinder on the guide rail pillar, rotary cylinder, upper limit is regulated bolt, lower limit is regulated bolt, regulate backstay, limiting plate, line slideway, the blade shaft bearing, be arranged on the one-way throttle valve at lift cylinder and rotary cylinder two ends, be arranged on the pilot-operated type check-valves of lift cylinder lower end, be arranged on the spherical bearing on the centrifuge working panel, be fixed on the blade shaft bearing and be located in rotation driving shaft on the spherical bearing, be fixed on the cutter hub of scraping that rotates driving shaft and be arranged on bowl inside, the described cutter hub of scraping comprises: be fixed on the scraper body on the rotation driving shaft, be arranged on the blade on the scraper body, be arranged on the stock guide on the scraper body.

The effect that the utility model is realized is: under the control of full-automatic control system, when bowl rotating speed during at discharge rate 80rpm, send the discharging instruction by signal transducer, simultaneously rotary drum be locked in alignment of shafts position by centring means can not beat, the driving of this scraper discharging device by lift cylinder and rotary cylinder drives the scraper body and carries out up and down and rotatablely move along guide rail, the solid particle that has separated on the drum inner wall is forced to scrape to draw off outside the rotary drum, after finishing along former route return, thereby realize automatic discharging.Regulate and scrape the stroke that cutter hub moves up and down by regulating the spacing adjusting bolt of lifting, guarantee to scrape the coverage that cutter hub moves up and down in rotary drum, avoid scraping cutter hub and in rotary drum, do not collide low head on the rotary drum; Regulate bolt and backstay and regulate and scrape the stroke that cutter hub rotatablely moves by regulating rotary stopper; Regulate the speed of scraping the cutter hub rotation and moving up and down by the current limliting screw on the unidirectional shutoff valve of regulating the cylinder two ends, obtain buffering in the time of making cylinder run to end of travel, avoid impingement phenomenon; Regulate the depth of parallelism of scraping cutter hub blade and drum inner wall by the level of regulating the guide rail pillar; Scrape adjusting bolt on the cutter hub blade by adjusting and finely tune distance with drum inner wall, guarantee that solid particle thoroughly scrapes totally; Can limit by limiting plate and to scrape cutter hub and cut off the power supply suddenly or the track route of the moment of dying, avoid the scraper body action malfunctioning and cause mechanical breakdown.
