Figure 1 shows that the structural representation of horizontal scraper discharging centrifuge in the utility model specific embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.

Described in ginseng Fig. 1, horizontal scraper discharging centrifuge, comprise revolving body assembly 10, frame component 20 and motor 30, revolving body assembly 10 is installed on frame component 20.Revolving body assembly 10 comprises main shaft 11, rotary drum 12 and big belt pulley 13, and rotary drum 12 and big belt pulley 13 are individually fixed in the two ends of main shaft 11, and the output of motor 30 is provided with small belt pulley 31, is in transmission connection between small belt pulley 31 and big belt pulley 13.

The surface of rotary drum 12 is distributed with number row aperture 121, the inwall of rotary drum 12 is equipped with one deck spacer screen 122, spacer screen 122 steel wire is pricked with it the rotary drum, spacer screen 122 need by the auxiliary upper lining net of different material and veil 123, veil 123 interface steel wire fastens, two ends cushion rubber compresses, and whole rotary drum is through dynamic balancing.

Main shaft 11 is made up of No. 45 steel, and through modifier treatment and scratch.Coordinate with taper seat between rotary drum 12 with main shaft 11, whole revolving body assembly passes through 14, two rolling bearings on frame component 20 with cantilevered.

Further, the diameter of aperture is 0.01m.

Further, motor 30 drives revolving body assembly 10 to rotate by six D type triangular form belts 32, and the small belt pulley on motor 32, built with slip clutch, makes machine start steady.

Further, big belt pulley 13 there is belt mechanical brake 131.

Frame component 20 comprises casing 21, chassis block 22, bearing housing 23 and base plate 24, casing 21 hides the outside in rotary drum 12, the end of casing 21 is removably fixed on chassis block 22 by bolt, the end of chassis block 22 is removably fixed on bearing housing 23 by bolt, and bearing housing 23 hides the outside in rolling bearing 14.

Further, casing 21 is formed by clad steel plate assembly welding, has tapping valve below frame component 20, is made up of two hydraulic valves, and the mother liquor of separation is washed net liquid and discharged through this valve respectively.Integration machine and motor are placed on base plate, place 10 rubber blankets 25, can absorb the vibrational energy of machine, motor cabinet bolt and bottom plate connecting below base plate.

The end cover of casing 21 has door closure 40, is connected with rocking arm articulated mounting, and configures rolling bearing between door closure 40 and casing 21, light to make door closure open and close.When closing door closure, ten eyelet bolts of available apparatus on body lock door closure and body, and its binding face acid and alkali-resistance rubber 41 seals.

Door closure 40 outer surface is equipped with doctor blade device 42 and scraper oil cylinder 43 etc., and inner surface is equipped with hopper 44, stretches out outside by door closure 40.The solid material that scraper scrapes slides along hopper, is discharged to outside through door closure.

Scraper oil cylinder 43 is connected in doctor blade device 42 by pin, doctor blade device 42 comprises knife rest and blade, and blade is wide formula, and stainless steel is made.With bolted on connection on knife rest.

Further, the ultimate position that scraper rotates, is collided by connecting rod and the travel switch be loaded on door closure and limits, and make machine insurance by colliding at the bottom of scraper cylinder piston rod and oil cylinder.

When machine operation, the full-speed operation of idle running drum, washes net liquid and enters rotary drum, cleaning screen cloth, and wash net liquid and discharge through washing net liquid outlet, after screen cloth cleans a period of time, inlet valve is opened automatically, and suspension enters in the rotary drum of full-speed operation along feed pipe.Under centrifugal action, in the middle part of suspension, most of liquid is through filter screen, lining net and the aperture roused on wall are thrown out of, tangential leakage fluid dram through casing flows to tapping valve, when inlet valve is opened, the valve of the mother liquor outlet of tapping valve is opened simultaneously, and will wash the valve closing of net liquid outlet, and mother liquor is discharged along mother liquor pipeline.Solid is then stayed in rotary drum, after charging valve is opened to the regular hour, automatically closes, and stop charging, material is dried in rotary drum.When drying to a certain extent, washing lotion valve is opened automatically, washing lotion sprays on solid material through cleaning hose, after washing certain hour, washing lotion valve cuts out automatically, now rotary drum continues under full-speed operation, after running to certain hour, material obtains sufficient drying, the knife rest automatic rotation that broad knife is now housed rises, solid material is scraped falls into inclination hopper, slide along hopper inclined-plane, outside discharge machine, when scraper rises to a certain distance from filter screen, connecting rod on doctor blade device brushes up against travel switch, scraper stops rising, and oppositely return origin-location immediately, enter next cycle, renew eventually like this, complete the Separation of Solid and Liquid of suspension.

It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ...
