Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge with convenient discharging. Background Art

[0002] Plate centrifuges are widely used in the pharmaceutical and chemical industries to separate solids from liquids. They primarily consist of a housing, a drum housed within the housing, and a drive mechanism. After a solid-liquid mixture enters the drum through the feed inlet, the drive mechanism rotates the drum, generating centrifugal force. This forces the liquid portion of the mixture through the filter holes in the drum's sidewalls and into the space between the housing and the drum. The liquid is then discharged through the liquid outlet at the bottom of the housing to a liquid storage tank outside the housing, while the solid portion is retained in the drum, achieving solid-liquid separation.

[0003] Due to the action of centrifugal force, solids usually adhere to the side wall of the inner cylinder of the centrifuge. Especially after compaction occurs, manual unloading is more difficult, resulting in low unloading efficiency. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects described in the background technology, thereby realizing a centrifuge with convenient discharging, using a scraper and a centrifuge to cooperate with each other to fully crush the solid material, greatly reducing the difficulty of unloading, and assisting workers to unload quickly.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution of the utility model is: a centrifuge with convenient discharging, comprising a cylinder and a drum arranged in the cylinder, a transmission shaft is provided in the center of the drum, the transmission shaft is powered by a drive motor, a support frame is provided on the base on the right side of the cylinder, a rotating shaft is installed on the support frame, a support plate is provided on the top of the rotating shaft, a scraper is provided below the support plate through a lifting assembly, and a rotating assembly is provided above the support plate.

[0006] Furthermore, a cylinder cover is hingedly connected to the top of the cylinder, a flip-cover oil cylinder is provided on the side of the cylinder, and the free end of the flip-cover oil cylinder is connected to the cylinder cover.

[0007] Furthermore, the rotating shaft is rotationally connected to the support frame through a bearing, and the rotating shaft is driven to rotate by a gear set and a rotating motor at the lower end.

[0008] Furthermore, a counterweight is provided below the support plate on the outer side of the rotating shaft, and the lifting assembly and the rotating assembly are provided on the support plate on the inner side of the rotating shaft.

[0009] Furthermore, the lifting component is a lifting cylinder or a lifting cylinder or a threaded screw combination, and the rotating component includes a motor and a gear set, and the motor drives the gear set to drive the lifting component to rotate.

[0010] Furthermore, the scraper is mounted on the free end of the lifting assembly via an L-shaped rod.

[0011] The beneficial effects of the centrifuge with convenient discharging of the utility model are:

[0012] The centrifuge of the utility model is convenient for discharging, and the scraper cooperates with the solid material rotating with the centrifuge to gradually break up the solid material into small pieces, thereby fully crushing the compacted solid material, effectively reducing the difficulty of discharging, and greatly improving the discharging efficiency.

[0013] The drive of the scraper is set on the outside of the centrifuge to minimize the impact on the normal operation of the centrifuge. The scraper is installed through an L-shaped rod. In conjunction with the rotating assembly, the contact force between the scraper and the fixed material can be freely adjusted to ensure safety during scraping. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they should not be understood as limitations on the present invention.

[0018] See also Figure 1 The centrifuge of this embodiment is convenient for discharging. The scraper and the centrifuge cooperate with each other to fully crush the solid material, greatly reducing the difficulty of unloading and assisting workers to unload quickly. It mainly includes a cylinder 1 and a drum 7 arranged in the cylinder 1. The top of the cylinder 1 is hinged with a cylinder cover 2, and the side of the cylinder 1 is provided with a flip cylinder 3. The free end of the flip cylinder 3 is connected to the cylinder cover 2. A transmission shaft 6 is provided in the center of the drum 7, and the transmission shaft 6 is powered by a drive motor 5.

[0019] A support frame 8 is provided on the base on the right side of the cylinder 1, and a rotating shaft 9 is installed on the support frame 8. The rotating shaft 9 is connected to the center of the support frame 8 through a bearing, and the support frame provides support for the rotating shaft to ensure the safety of the rotating shaft during operation. The rotating shaft 9 is driven to rotate by the gear set 10 and the rotating motor at the lower end. A support plate 12 is provided on the top of the rotating shaft 9, and a scraper 17 is provided below the support plate 12 through a lifting assembly 14. A rotating assembly 13 is provided above the support plate 12, and a counterweight block 11 is provided below the support plate 12 outside the rotating shaft 9. The lifting assembly 14 and the rotating assembly 13 are arranged on the support plate 12 inside the rotating shaft 9.

[0020] The lifting assembly 14 is a lifting cylinder or a lifting cylinder or a threaded screw combination, which is used to adjust the height of the scraper 17. The rotating assembly 13 includes a motor and a gear set. The motor drives the gear set to drive the lifting assembly 14 to rotate, thereby driving the scraper to rotate and adjust the contact force between the scraper and the solid material. The scraper 17 is installed at the free end of the lifting assembly 14 by an L-shaped rod 16 to increase the adjustment range of the scraper.

[0021] After the centrifuge is finished filtering, open the flip cover of the small window, and the rotating motor drives the gear group to rotate the shaft, rotate the scraper to the top of the small window, and the lifting assembly controls the scraper to move down to the appropriate height in the cylinder. Start the drive motor, and the drum drives the fixed material to rotate. The rotating assembly controls the lifting assembly to rotate, driving the scraper to rotate until it contacts the fixed material and maintains a certain force to gradually scrape off the compacted fixed material. After scraping is completed, the lifting assembly, rotating assembly and rotating motor cooperate to control the scraper to reset, and then the cylinder cover can be opened for workers to unload.
