[0002] When the fully automatic centrifuge is in use, the mixed solution is passed through the rotation of the centrifuge inner tank to effectively separate the solid and liquid materials in the mixed solution, and the assembled scraper is used to discharge the solid after solid-liquid separation, which is convenient for subsequent centrifugal discharge. However, there are still some problems when using the scraper discharge device of the existing fully automatic centrifuge.

[0003] In the prior art, the authorized publication (announcement) number: CN110773335A, "An automatic sedimentation scraper unloading device for a centrifuge", includes a pneumatic mechanism and a scraper mechanism, wherein the scraper mechanism is fixedly mounted on the pneumatic mechanism. By connecting the scraper mechanism and the pneumatic mechanism, the air pressure is used to drive the lifting rod to move, so that the scraper mechanism can move up and down in the centrifuge drum. Compared with manual scraper unloading, it is safer and more efficient.

[0004] During the operation of the above-mentioned device, an elastic scraper fixing mechanism is provided in the scraper assembly, and the first scraper blade, the second scraper blade and the third scraper blade are all installed in the scraper mounting groove through the elastic scraper fixing mechanism, so that the scraper blades are protected and the side walls of the drum are not scratched. However, when in use, the scraper is not convenient to adjust to different angles according to the rotation direction of the inner tank, which has certain limitations during use and is not convenient for quick replacement of the scraper.

[0005] In the prior art, the authorized disclosure (announcement) number: CN220111339U in "A scraper-feeding automatic slag discharge centrifuge" includes a lower support frame, the upper surface of the lower support frame is fixedly connected to the upper support frame, the interior of the upper support frame is fixedly installed with a main motor, and the output end of the main motor is connected to a driving wheel; the water inlet and the water outlet are merged to leave more space for the design of the rotating rod, the design of the rotating rod is simpler, the assembly is more convenient, the bag-free design has a lower overall use cost, and when the drum rotates at high speed, the suspension is separated into solid and liquid. At this time, the solid particles are in the drum, and the liquid moves upward along the water inlet under the action of centrifugation and is discharged outward from the water outlet;

[0006] In the prior art, the "scraper bottom discharge fully automatic sedimentation centrifuge" in the authorization publication (announcement) number: CN206009010U includes a frame, on which a motor, a transmission assembly, a rotating drum, a cover, a scraper drive device, a feed pipe and a discharge port are provided; at least one spacer is provided in the rotating drum, and at least one connecting port is provided on the spacer; the spacer divides the rotating drum into at least two cavities, each cavity is provided with a scraper, and the scraper is driven by a scraper drive device;

[0007] During the operation of the above-mentioned device, the rotation of the scraper is likely to occupy the internal use space of the centrifuge and affect the normal centrifugal effect. In addition, when multiple sets of scrapers are set up, it is inconvenient to adjust the scraper height according to the usage situation. At the same time, when scraping the inner surface of the liner at the same time, it is likely to generate a large extrusion force, which affects the stability of the scraper bracket.

[0038] 3. The sedimentation fully automatic centrifuge with scraper unloading and the method thereof are provided with a support ring and a slider for stable support, which improves the stability of the connection between the second telescopic rod and the rotating seat, and cooperates with the base assembled with the rotating seat to effectively form a stable assembly for the scraper body, and the scraper body can be conveniently disassembled, and different scraper bodies can be effectively replaced according to usage.

[0068] The third step: when controlling the internal telescopic adjustment of the scraper assembly 10, the motor in the second telescopic rod 20 can be controlled to start first, and the rotating seat 22 connected to the output shaft is adjusted to cooperate with the support ring 21 and the slider 24 to rotate stably, so as to promote the base 25 connected under the rotating seat 22 and the scraper body 32 installed on the base 25 to contact the inner liner 2, so as to clean the solids adsorbed on the inner liner 2. During cleaning, the elastic adjustment between the paddle 33 and the return spring 34 on the base 25 and the use of the pressure rod 35 can be coordinated to control the base 25 to adjust a certain angle when it is over-pressurized and reset it when it is not pressurized. In addition, the use of the cleaning pipe 36 can be coordinated to blow the solids downward during the unloading process to reduce the flying adsorption on the scraper body 32.

[0069] Step 4: When the scraper body 32 is in use, the scraper body 32 can be replaced according to the use requirements, and the base 25 connected to the scraper body 32 and the extrusion block 28 assembled by the extrusion rod 26 assembled inside the base 25 can be used to extrude and limit the limiting component 29, thereby controlling the nested card block 31 to prevent it from falling off, and when disassembling, the extrusion block 28 is controlled to unlock and squeeze the limiting component 29, and through the elastic push of the extrusion spring 30, the limiting component 29 can be controlled to disengage from the extrusion of the card block 31, and the scraper body 32 can be removed and replaced, thereby controlling the disassembly and assembly stability of the scraper body 32 when in use.

[0070] When the scraper body 32 contacts the inner pot 2 for cutting, the base 25 assembled with the scraper body 32 and the rotating seat 22 can be controlled to rotate elastically. In order to prevent hard contact between the scraper body 32 and the inner pot 2, the dial plate 33 on the base 25 and the return springs 34 on both sides can be controlled to form mutual extrusion, and the pressure rod 35 assembled and rotated between the base 25 and the rotating seat 22 can effectively form constant pressure control, thereby preventing the scraper body 32 from being excessively squeezed when contacting the inner pot 2. When the pressure is too large, it can be deflected, and the dial plate 33 can be controlled to rotate, squeezing the return spring 34 on one side of the dial plate 33, and through the control of the elastic force, the protection of the contact between the scraper body 32 and the inner pot 2 is improved. When cutting, the return spring 34 on the other side can be used to reset the center. When a different scraper body 32 needs to be replaced for work, the built-in electric The control screw 27 threadedly adjusts the extrusion rod 26 to move upward, and when it moves upward, the extrusion block 28 installed on the extrusion rod 26 can be controlled to disengage the extrusion control of the limit assembly 29, and the limit assembly 29 can cooperate with the extrusion spring 30 connected on the upper side to control it to slide elastically toward the side of the extrusion rod 26, and after sliding to the end, the limit assembly 29 will be disengaged from the control of the clamping block 31, and the scraper body 32 can be held by hand to disengage the clamping block 31 installed by the base 25, and the force applied is small, which can reduce the use of force when installing a new scraper body 32, facilitates quick assembly and positioning, and avoids scratching the assembler caused by slipping when applying force, and reverse assembly can be used, so that the scraper body 32 can be stably assembled, and in the later use, the nested cleaning pipe 36 can be used in conjunction with blanking to reduce material flying and reduce the amount of material remaining on the scraper body 32.
