Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge technology, and in particular to a flat-plate scraper-type centrifuge for unloading material. Background Technology
[0002] The scraper centrifuge is a type of machine with low energy consumption, stable performance, and good separation effect. It is widely used in the separation process of chemical, food, salt, mining, pharmaceutical and other industries to continuously complete processes such as feeding, dewatering, washing and unloading. It has high production efficiency and a high degree of automation. The scraper centrifuge is an advanced separation equipment.
[0003] A search revealed that Chinese Patent Publication No. CN216826720U discloses a flat-plate scraper-type automatic centrifuge with bottom discharge, comprising a housing, a drain pipe, and a motor. The features include: a drain pipe on the left side of the housing for discharging the liquid phase separated within the drum; a bearing at the center of the upper part of the housing; a feed pipe within the bearing; a pulley on the feed pipe; a motor on the housing; an output shaft on the motor; a pulley on the output shaft; a belt between the pulley and the pulley; when the motor is started, the output shaft rotates, causing the pulley to rotate, which in turn drives the pulley to rotate, thus causing the feed pipe to rotate within the bearing; a drum within the housing; and a stirring rod within the drum.
[0004] In order to solve the problem that the filter holes on the drum are easily blocked by materials, the above-mentioned patent sets scrapers and brushes at both ends of the top wall of the shell. The brushes clean the inner wall of the drum that is not completely scraped after the scraper removes the solid phase in time.
[0005] However, since the brushes are always placed inside the drum, they block the separation holes on the drum. During the centrifugal separation of raw materials, the brush bristles not only affect the centrifugal separation effect of the raw materials, but also adhere to some raw materials. With prolonged use, the material adhering to the brushes accumulates more and more, which affects the cleaning effect on the inner wall of the drum, indicating room for improvement.

[0039] In this embodiment, a sealed bearing is fixedly sleeved on the centrifuge cylinder 3.

The top of the shell 2 is provided with a feed pipe for conveying raw materials into the centrifuge cylinder 3. The bottom of the centrifuge cylinder 3 is rotatably connected with a discharge pipe. One end of the discharge pipe is fixedly sleeved with a sealed bearing, and the outer wall of the sealed bearing is fixedly connected to the centrifuge cylinder 3 for discharging the material inside the centrifuge cylinder 3. The shell 2 is provided with a discharge pipe for discharging the separated material. Both the discharge pipe and the discharge pipe are provided with valves.
[0040] Working principle: During use, the control panel 13 is used to drive and control cylinder 4, cylinder 6, liquid pump 11, air pump 12, solenoid valve and motor 14.
[0041] First, the raw materials are fed into the centrifuge cylinder 3 through the feed pipe. Then, the gear 15 is rotated by the motor 14 and drives the gear ring 16, which in turn drives the centrifuge cylinder 3 to rotate on the shell 2, thereby achieving the effect of centrifugal separation of the raw materials.
[0042] During the centrifugal separation of raw materials, the cylinder 4 can be extended and driven according to the user's needs, so that the output end of the cylinder 4 drives the flat scraper 5 to move downward a certain distance and make the flat scraper 5 contact the inner wall of the centrifuge cylinder 3, thereby achieving the effect of scraping and cleaning the inner wall of the centrifuge cylinder 3 and improving the effect of centrifugal separation of raw materials.
[0043] When the centrifuge drum 3 needs to be cleaned, the flat scraper 5 is driven by cylinder 4 to contact the inner wall of the centrifuge drum 3, and the cleaning plate 7 is moved downward a certain distance by the extension drive of cylinder 6, so that the brush and multiple through holes on the cleaning plate 7 correspond to the outer wall of the centrifuge drum 3. Then, the centrifuge drum 3 is rotated by the drive of motor 14, so that the flat scraper 5 can scrape and clean the raw materials inside the centrifuge drum 3. At the same time, the brush can clean the outer wall of the centrifuge drum 3.
[0044] Meanwhile, during the cleaning process of the centrifuge drum 3, the air pump 12 and the liquid pump 11 can be controlled and driven according to the user's needs. When the air pump 12 is driven, the solenoid valve at one end of the corresponding three-way pipe 10 is opened, and the gas is delivered to the cavity on the cleaning plate 7 through the action of the hose 9 and the round pipe 8, and sprayed out through multiple through holes 17. At this time, the generated airflow can not only act on the brush, but also act on the centrifuge drum 3, thereby achieving a further cleaning effect on the raw materials.
[0045] When the liquid pump 11 is driven, the solenoid valve at one end of the corresponding three-way pipe 10 is opened, and the liquid is transported to the cavity on the cleaning plate 7 through the action of the hose 9 and the round pipe 8. The liquid is sprayed out through multiple through holes 17 and acts on the brush and centrifuge cylinder 3, thereby achieving the effect of rinsing the brush and centrifuge cylinder 3, and thus achieving the effect of further cleaning the raw materials.
[0046] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can a composite scraping and cleaning effect be achieved on the raw materials after centrifugal separation, but also the effect of avoiding the adhesion of raw materials to the brush can be achieved, thereby improving the centrifugal separation and cleaning effect of the raw materials. Moreover, the structure is simpler, more convenient, and more practical.
