Description

Technical Field

[0001] This application relates to the field of centrifuge technology, specifically a centrifuge cleaning device. Background Technology

[0002] A centrifuge is a mechanical device that uses centrifugal force to separate the components in a mixture of liquids and solid particles, or liquids and liquids. Its core principle is to generate centrifugal force (which can be thousands of times the acceleration of gravity) through high-speed rotation, thereby separating substances of different densities in the mixture.

[0003] Currently, centrifuge cleaning devices generally use scrapers and brushes for cleaning. The scrapers and brushes are positioned using positioning rods, and the brushes and scrapers are usually bolted to the outer wall of the positioning rods, making it convenient for operators to replace them. However, during use, the cleaning ends of the scrapers and brushes will wear down. When the scrapers and brushes are worn, their cleaning effect will decrease, requiring replacement. Replacing the scrapers and brushes only when they are worn down, and frequent shutdowns for replacement may reduce centrifugation efficiency and increase the replacement cost of the scrapers and brushes. Utility Model Content

[0004] The purpose of this application is to provide a centrifuge cleaning device that solves the problems of the centrifuge cleaning devices proposed in the background art, which generally use scrapers and brushes for cleaning. The scrapers and brushes are positioned by positioning rods, and the brushes and scrapers are generally fixed to the outer wall of the positioning rods with bolts, which facilitates the replacement of scrapers and brushes by the staff. However, during use, the cleaning ends of the scrapers and brushes will wear down, and when the scrapers and brushes are worn, their cleaning effect will decrease, thus requiring the replacement of scrapers and brushes. Replacing scrapers and brushes only when they are worn down, and frequent shutdowns for replacement may reduce centrifugation efficiency and increase the replacement cost of scrapers and brushes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a centrifuge cleaning device, including an outer cylinder. A rotating main shaft is rotatably mounted on the inner top wall of the outer cylinder. A rotating drum is fixedly mounted on the upper end of the rotating main shaft. A bearing seat is mounted on the lower end of the rotating drum, located outside the rotating main shaft. The lower end of the bearing seat is fixedly mounted to the inner bottom wall of the outer cylinder. A cylinder cover is hinged to the upper outer wall of the outer cylinder. An electric push rod is fixedly mounted on the upper end of the cylinder cover. A connecting plate is fixedly mounted on the telescopic end of the electric push rod. A connecting column is fixedly mounted on the lower end of the connecting plate. Connecting rods are fixedly installed on the outer walls of both sides. A storage shell is fixedly installed on the outer wall of each connecting rod. A scraper and a brush are slidably connected to the inner walls of the two storage shells. A set of telescopic rods is fixedly installed on the inner walls of the two storage shells. The telescopic ends of each set of telescopic rods are fixedly installed with the corresponding scraper and brush. A spring is sleeved on the outer wall of each telescopic rod. The two ends of each spring abut against the inner walls of the corresponding storage shell, scraper, and brush. A rotating mechanism for rotating the outer cylinder is provided on the outer wall of the outer cylinder.

[0007] By adopting the above technical solution, when the main shaft rotates, the drum can be driven to rotate with the cooperation of the bearing seat. The electric push rod drives the connecting plate, connecting column, connecting rod and receiving shell to move vertically, which in turn drives the corresponding scraper and brush to move vertically. When the drum rotates, it can play a cleaning role with the fixed scraper and brush. When the scraper and brush wear down, they can be pushed outward with the cooperation of the telescopic rod and spring, so that the brush and scraper can better clean the drum. When the rotating mechanism drives the outer cylinder to rotate and tilt, it can facilitate the unloading of cleaned materials, reduce the replacement cost of brush and scraper, and enhance the cleaning efficiency of brush and scraper.

[0008] Optionally, the rotating mechanism includes bases fixedly installed on the outer walls of both sides of the outer cylinder, with a rotating column fixedly installed on the outer wall of each base, and the same U-shaped frame rotatably passing through the outer wall of each rotating column.

[0009] By adopting the above technical solution, the U-shaped frame can provide rotational support for the rotating column, while the rotating column can fix the base. Then, when the rotating column rotates, it can drive the outer cylinder to rotate with the cooperation of the base.

[0010] Optionally, a reciprocating motor is installed on the outer wall of one side of the U-shaped frame, and the output shaft of the reciprocating motor is fixedly installed with one of the rotating columns.

[0011] By adopting the above technical solution, the U-shaped frame can fix the reciprocating motor, which can drive the rotating column to rotate, thereby facilitating the rotation and tilting of the outer cylinder, making it convenient for workers to tilt and pour out the material inside the drum.

[0012] Optionally, lugs are welded to the outer walls on both sides of the cylinder cover, and a cylinder is rotatably installed on the lower end of each lug and the outer wall of the corresponding base.

[0013] By adopting the above technical solution, the cylinder cover can fix the lug, and the lug and the base can respectively provide rotational support for both ends of the cylinder. Then, when the cylinder extends or retracts, it can drive the cylinder cover to flip open and close along the hinge between the cylinder cover and the outer cylinder.

[0014] Optionally, a stepper motor is installed at the lower end of the outer cylinder, and the output shaft of the stepper motor is fixedly installed with the rotating main shaft.

[0015] By adopting the above technical solution, the outer cylinder can fix the stepper motor, and the stepper motor can drive the rotating spindle to achieve variable speed rotation.

[0016] Optionally, a discharge pipe is fixedly installed at the lower end of the outer cylinder, and a valve is installed on the outer wall of the discharge pipe.

[0017] By adopting the above technical solution, the valve can be used to open and close the discharge pipe, which can discharge the centrifugally separated liquid inside the drum.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application utilizes a rotating main shaft. With the cooperation of the bearing housing, the rotating drum can be driven to rotate. An electric push rod drives the connecting plate, connecting column, connecting rod, and receiving shell to move vertically, which in turn drives the corresponding scraper and brush to move vertically. When the drum rotates, the fixed scraper and brush perform a cleaning function. When the scraper and brush wear down, they can be pushed outwards with the cooperation of the telescopic rod and spring, thus better enabling the brush and scraper to clean the drum. When the rotating mechanism drives the outer cylinder to rotate and tilt, it facilitates material unloading, reduces the replacement cost of the brush and scraper, and enhances the cleaning efficiency of the brush and scraper.

[0027] Please see Figure 1-4 This application provides a technical solution: a centrifuge cleaning device, including an outer cylinder 1, a rotating main shaft 14 rotatably mounted on the inner top wall of the outer cylinder 1, a rotating drum 2 fixedly mounted on the upper end of the rotating main shaft 14, a bearing seat 15 mounted on the lower end of the rotating drum 2 located outside the rotating main shaft 14, the lower end of the bearing seat 15 fixedly mounted to the inner bottom wall of the outer cylinder 1, a cylinder cover 3 hinged to the upper outer wall of the outer cylinder 1, an electric push rod 4 fixedly mounted on the upper end of the cylinder cover 3, a connecting plate 5 fixedly mounted on the telescopic end of the electric push rod 4, a connecting column 6 fixedly mounted on the lower end of the connecting plate 5, and two connecting columns 6... Connecting rods 7 are fixedly installed on the outer walls of the sides. A storage shell 8 is fixedly installed on the outer wall of each connecting rod 7. A scraper 11 and a brush 12 are slidably connected to the inner walls of the two storage shells 8. A set of telescopic rods 9 are fixedly installed on the inner walls of the two storage shells 8. The telescopic ends of each set of telescopic rods 9 are fixedly installed with the corresponding scraper 11 and brush 12. A spring 10 is sleeved on the outer wall of each telescopic rod 9. The two ends of each spring 10 abut against the inner walls of the corresponding storage shell 8, scraper 11 and brush 12. A rotating mechanism for rotating the outer cylinder 1 is provided on the outer wall of the outer cylinder 1.

[0028] In the technical solution of this application, when the main shaft 14 rotates, the drum 2 can be driven to rotate with the cooperation of the bearing seat 15. The electric push rod 4 drives the connecting plate 5, connecting column 6, connecting rod 7 and receiving shell 8 to move vertically, which in turn drives the corresponding scraper 11 and brush 12 to move vertically. When the drum 2 rotates, it can play a cleaning role by fixing the scraper 11 and brush 12. When the scraper 11 and brush 12 are worn, they can be pushed outward with the cooperation of the telescopic rod 9 and spring 10, so that the brush 12 and scraper 11 can better clean the drum 2. When the rotating mechanism drives the outer cylinder 1 to rotate and tilt, it can facilitate the cleaning and unloading of materials, reduce the replacement cost of brush 12 and scraper 11, and enhance the cleaning efficiency of brush 12 and scraper 11.

[0029] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, a stepper motor 13 is installed at the lower end of the outer cylinder 1. The output shaft of the stepper motor 13 is fixedly installed with the rotating main shaft 14. The outer cylinder 1 can fix the stepper motor 13, and the stepper motor 13 can drive the rotating main shaft 14 to rotate at different speeds. A discharge pipe 16 is fixedly installed at the lower end of the outer cylinder 1. A valve 17 is installed on the outer wall of the discharge pipe 16. The valve 17 can open and close the discharge pipe 16, and the discharge pipe 16 can discharge the centrifugally separated liquid inside the drum 2.

[0030] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, the rotating mechanism includes bases 23 fixedly installed on the outer walls of both sides of the outer cylinder 1. Each base 23 has a rotating column 18 fixedly installed on its outer wall. The same U-shaped frame 20 is rotatably inserted through the outer wall of each rotating column 18. The U-shaped frame 20 can provide rotational support for the rotating column 18, and the rotating column 18 can fix the base 23. When the rotating column 18 rotates, it can drive the outer cylinder 1 to rotate with the cooperation of the base 23. A reciprocating motor 19 is installed on the outer wall of one side of the U-shaped frame 20. The output shaft of the reciprocating motor 19 is fixedly installed with one of the rotating columns 18. The U-shaped frame 20 can fix the reciprocating motor 19, and the reciprocating motor 19 can drive the rotating column 18 to rotate, which facilitates the rotation and tilting of the outer cylinder 1, making it convenient for the staff to tilt and pour out the material inside the drum 2.

[0031] In the technical solution of this application, such as Figure 1 and Figure 2As shown, lugs 21 are welded to the outer walls on both sides of the cylinder cover 3. A cylinder 22 is rotatably installed on the lower end of each lug 21 and the outer wall of the corresponding base 23. The cylinder cover 3 can fix the lugs 21, while the lugs 21 and the base 23 can provide rotational support for the two ends of the cylinder 22. When the cylinder 22 extends or retracts, it can drive the cylinder cover 3 to flip open and close along the hinge between the cylinder cover 3 and the outer cylinder 1.

[0032] In use, the cylinder 22 opens and closes the cylinder cover 3, facilitating the loading of materials into the inner drying cylinder. When the cylinder cover 3 is closed, the stepper motor 13 drives the rotating main shaft 14 to rotate. The rotating main shaft 14, with the cooperation of the bearing seat 15, drives the drum 2 to rotate, thus centrifugally rotating the materials and facilitating solid-liquid separation. The liquid can be discharged from the discharge pipe 16. When it is necessary to clean the solids inside the drum 2, the drum 2 continues to rotate, and the electric push rod 4 drives the connecting plate 5, connecting column 6, connecting rod 7, and receiving shell 8 to rotate vertically. The vertical movement of the drum 2 can then drive the corresponding scraper 11 and brush 12 to move vertically. When the drum 2 rotates, it can clean the fixed scraper 11 and brush 12. When the scraper 11 and brush 12 are worn, they can be pushed outward with the cooperation of the telescopic rod 9 and spring 10, so that the brush 12 and scraper 11 can better clean the drum 2. When the reciprocating motor 19 drives the rotating column 18 and the outer cylinder 1 to rotate and tilt, it can facilitate the cleaning and unloading of materials, reduce the replacement cost of brush 12 and scraper 11, and enhance the cleaning efficiency of brush 12 and scraper 11.
