Description

A horizontal centrifuge with a residual material cleaning structure Technical Field

[0001] This utility model belongs to the field of centrifuge technology, specifically relating to a horizontal centrifuge with a residual material cleaning structure. Background Technology

[0002] During the production of protein peptides, operators use horizontal centrifuges to separate the solid and liquid components of the mixture containing protein peptides, such as fermentation broth and extract, in order to obtain protein peptide products with high purity.

[0003] A horizontal centrifuge, as disclosed in publication number "CN204974216U", includes a spiral, a drum, a casing, and a differential. The spiral is installed inside the drum, and the casing is installed outside the drum. The spiral is divided into a straight section and a conical section. The spiral blades include a pushing surface and a non-pushing surface. The pushing surface is welded with a tungsten carbide layer. A fan-shaped inclined plate of a certain height is spirally arranged between the spiral blades of the straight section spiral. The material enters the centrifuge through the feed inlet in the middle of the spiral for separation. The solid phase outlet is located on one side of the conical section spiral. A solid phase discharge device, a squirrel-cage type rotary drum structure, is installed on the drum at the solid phase outlet. The differential is located on the conical section of the spiral. The fan-shaped inclined plate structure on the straight section of the spiral effectively allows the solid phase to quickly reach the inner wall of the drum. The entire device is rationally designed, easy to use and process, and achieves effective separation, making it suitable for further widespread application.

[0004] The inventors believe that the above-mentioned horizontal centrifuge can also be used in the production and processing of protein peptides. However, when the horizontal centrifuge is in use, the rotating drum generates a rotating airflow, which causes some residual material to adhere to the inner wall of the shell and the outer wall of the drum. When the operator cleans this residual material, the shell needs to be opened for manual cleaning, which is time-consuming and labor-intensive, thus causing inconvenience to the cleaning work of the horizontal centrifuge.

[0005] Therefore, this utility model provides a horizontal centrifuge with a residual material cleaning structure to solve the above problems. Summary of the Invention

[0006] The purpose of this utility model is to provide a horizontal centrifuge with a residual material cleaning structure, which aims to solve the problem that in the existing horizontal centrifuge, when the drum rotates in the shell, a rotating airflow is generated, which causes some residual material to adhere to the inner wall of the shell and the outer wall of the drum. When the operator cleans this residual material, it is necessary to open the shell for manual cleaning, which is time-consuming and laborious, thus causing inconvenience to the cleaning work of the horizontal centrifuge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a horizontal centrifuge with a residual material cleaning structure, comprising a frame, a shell connected to the inner surface of the top of the frame, a rotating drum disposed inside the shell, a discharge port disposed on the bottom surface of one side of the shell, and a liquid outlet disposed on the bottom surface of the other side of the shell, a through groove opened on the top surface of the shell, a protrusion connected to the top surface of the shell outside the through groove, mounting brackets connected to the top surfaces of the four corners of the frame, electric push rods symmetrically connected to the top surfaces of the mounting brackets, the movable end of the electric push rod passing through the mounting bracket and connected to the top surface of the movable plate, a through pipe embedded in the bottom surface of the movable plate, and nozzles connected in a horizontal array on the bottom surface of the through pipe.

[0008] In order to achieve the delivery of cleaning water, as a preferred embodiment of the horizontal centrifuge with residual material cleaning structure of this utility model, a telescopic hose is connected to the top surface of the middle position of the through pipe. The other end of the telescopic hose passes through the movable plate and the mounting frame and is connected to the output end of the water pump. The input end of the water pump is connected to the liquid extraction pipe, and the other end of the liquid extraction pipe extends into the water tank.

[0009] In order to achieve normal operation control of the electric push rod and water pump, as a preferred embodiment of the horizontal centrifuge with residual material cleaning structure of this utility model, the electric push rod and water pump are electrically connected through a control switch and an external power supply.

[0010] In order to enable the movable plate to move into the inside of the protrusion, in a preferred embodiment of the horizontal centrifuge with a residual material cleaning structure of this utility model, the position and size of the movable plate are matched with the position and size of the protrusion, and a sliding connection is formed between the movable plate and the protrusion.

[0011] To achieve the rotation and fixation of the baffle, in a preferred embodiment of the horizontal centrifuge with a residual material cleaning structure of this utility model, a hinge is connected to the front surface of the protrusion, the movable end of the hinge is connected to the front surface of the baffle, and a butterfly bolt is connected through the rear surface of the baffle, the other end of the butterfly bolt is threadedly connected to a fixing hole opened on the rear surface of the protrusion.

[0012] In order to achieve a seal between the baffle and the protrusion, in a preferred embodiment of the horizontal centrifuge with a residual material cleaning structure of the present invention, a sealing ring is connected to the bottom surface of the baffle, one end of the sealing ring extends into a groove opened on the top surface of the protrusion, and the sealing ring and the protrusion form an engaging structure through the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes an electric push rod to move a movable plate, allowing it to slide inside the protrusion. At this point, a nozzle at the bottom of the movable plate can pass through a groove and extend into the housing. Then, a water pump is activated, drawing cleaning water from the tank via a suction pipe and delivering it into the connecting pipe via a flexible hose. The nozzle at the bottom of the connecting pipe can then spray water into the housing, effectively cleaning the inner wall of the housing and the outer wall of the drum. This eliminates the need for manual cleaning by operators, simplifying the cleaning process for horizontal centrifuges.

[0015] This utility model uses a baffle that is rotated by a hinge so that the bottom of the baffle comes into contact with the top of the protrusion. At this time, the sealing ring at the bottom of the baffle will engage in the slot. Then, a butterfly bolt is used to screw the baffle into the fixing hole, so that the position of the baffle is fixed on the protrusion. This allows the baffle to cover and protect the opening at the top of the protrusion, preventing debris from entering the housing through the protrusion. Attached Figure Description

[0024] Please refer to Figures 1-5. This utility model provides the following technical solution: A horizontal centrifuge with a residual material cleaning structure includes a frame 1. A shell 2 is connected to the inner surface of the top of the frame 1. A drum 3 is provided inside the shell 2. A discharge port 4 is provided on the bottom surface of one side of the shell 2, and a liquid outlet 5 is provided on the bottom surface of the other side of the shell 2. A through groove 6 is opened on the top surface of the shell 2. A protrusion 7 is connected to the top surface of the shell 2 outside the through groove 6. Mounting brackets 8 are connected to the top surfaces of the four corners of the frame 1. Electric push rods 9 are symmetrically connected to the top surface of the mounting brackets 8. The movable end of the electric push rod 9 passes through the mounting brackets 8 and is connected to the top surface of the movable plate 10. A through pipe 11 is embedded on the bottom surface of the movable plate 10. Nozzles 12 are connected in a horizontal array on the bottom surface of the through pipe 11.

[0025] Preferably, a telescopic hose 13 is connected to the top surface of the middle position of the pipe 11. The other end of the telescopic hose 13 passes through the movable plate 10 and the mounting bracket 8 and is connected to the output end of the water pump 14. The input end of the water pump 14 is connected to a liquid extraction pipe 15, and the other end of the liquid extraction pipe 15 extends into the water tank 16.

[0026] In practical use, the water pump 14 is connected to the top of the mounting frame 8, and the water tank 16 is connected to the top surface of the bottom end of the frame 1. By starting the water pump 14, the input end of the water pump 14 draws out the cleaning water inside the water tank 16 through the liquid extraction pipe 15, and the cleaning water is input into the through pipe 11 through the telescopic hose 13. In this way, the nozzle 12 at the bottom of the through pipe 11 will flush the residual material on the inner wall of the housing 2 and the outer wall of the drum 3.

[0027] Preferably, the electric push rod 9 and the water pump 14 are electrically connected via a control switch and an external power source.

[0028] In practical use, the water pump 14 can be a high-pressure water pump, and the electric push rod 9 and the water pump 14 can be controlled by a switch.

[0029] Preferably, the position and size of the movable plate 10 match the position and size of the protrusion 7, and a sliding connection is formed between the movable plate 10 and the protrusion 7.

[0030] In actual use, the movable plate 10 can slide up and down inside the protrusion 7.

[0031] Preferably, a hinge 17 is connected to the front surface of the protrusion 7, the movable end of the hinge 17 is connected to the front surface of the baffle 18, a butterfly bolt 19 is connected through the rear surface of the baffle 18, and the other end of the butterfly bolt 19 is threadedly connected to the fixing hole 20 opened on the rear surface of the protrusion 7.

[0032] In practical use, the baffle 18 can be rotated by the hinge 17, so that the baffle 18 can be in an open or closed state on the protrusion 7. When the baffle 18 is in the closed state, the butterfly bolt 19 is inserted through the baffle 18 and screwed into the fixing hole 20, so that the position of the baffle 18 can be fixed on the protrusion 7.

[0033] Preferably, a sealing ring 21 is connected to the bottom surface of the baffle 18, and one end of the sealing ring 21 extends into the groove 22 opened on the top surface of the protrusion 7. The sealing ring 21 and the protrusion 7 form an engaging structure through the groove 22.

[0034] In actual use, when the bottom surface of the baffle 18 contacts the top surface of the protrusion 7, the sealing ring 21 at the bottom of the baffle 18 will move and engage in the slot 22, thereby increasing the sealing between the baffle 18 and the protrusion 7.

[0035] Working principle: When using this horizontal centrifuge with a residual material cleaning structure, the materials to be separated in protein peptide production are fed into the rotating drum 3 through the feed inlet. The drive device drives the rotating drum 3 to rotate, allowing the protein peptide production materials to undergo solid-liquid separation under the action of the spiral inside the rotating drum 3. The solid material of the protein peptide production materials is discharged through the discharge port 4, while the liquid material of the protein peptide production materials is discharged through the liquid outlet 5, thus achieving solid-liquid separation. The rotating drum 3 operates within the shell 2. During rotation, some residual material adheres to the inner wall of the housing 2 and the outer wall of the drum 3. When the operator needs to clean this residual material, first unscrew the butterfly bolt 19, allowing the baffle 18 to rotate via the hinge 17. At this time, the opening at the top of the protrusion 7 will be exposed. Then, start the electric push rod 9, causing the movable end of the electric push rod 9 to move the movable plate 10, allowing the movable plate 10 to slide into the inside of the protrusion 7. At this time, the nozzle 12 on the bottom pipe 11 of the movable plate 10 will pass through the through groove 6 and enter the interior of the housing 2. Then, start the water pump 1. 4. Pump 14 draws cleaning water from the water tank 16 through the suction pipe 15. The cleaning water is then introduced into the connecting pipe 11 through the telescopic hose 13. The nozzle 12 at the bottom of the connecting pipe 11 flushes the remaining material on the inner wall of the housing 2 and the outer wall of the drum 3, thus cleaning the remaining material and preventing manual cleaning by the operator, facilitating the cleaning of the horizontal centrifuge. After cleaning, the cleaning water is discharged through the drain port at the bottom of the housing 2. At this point, the electric push... The rod 9 will then reset the nozzle 12, and the baffle 18 will be rotated by the hinge 17 so that the bottom surface of the baffle 18 contacts the top surface of the protrusion 7. At this time, the sealing ring 21 at the bottom of the baffle 18 will move and engage in the slot 22, thereby increasing the sealing between the baffle 18 and the protrusion 7. Then, the butterfly bolt 19 will be used to screw the baffle 18 into the fixing hole 20, so that the position of the baffle 18 is fixed on the protrusion 7, so that the baffle 18 can block and protect the opening at the top of the protrusion 7, preventing debris from entering the interior of the housing 2 through the protrusion 7.
