A butterfly centrifuge

Abstract

This invention belongs to the field of centrifuge technology, specifically a disc centrifuge, comprising a motor, a vertical shaft mounted on the motor, a rotating drum mounted on the vertical shaft, a piston installed inside the rotating drum, a nylon sealing ring installed inside the rotating drum, the piston connected to the nylon sealing ring, and a nylon valve installed on one side of the inside of the rotating drum. This invention, through a control system, activates the solenoid valve of the water distribution device, instantly opening the discharge channel of the operating water. The pressure in the operating water chamber drops rapidly. Under the action of the hydrostatic pressure of the liquid inside the rotating drum, the piston moves rapidly downward, opening the slag discharge port. At this time, the solid material deposited on the drum wall is thrown out at high speed under the action of centrifugal force, avoiding the loss of clarified liquid, improving material yield, and allowing slag discharge without interrupting the feed, greatly improving the continuity of production and processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a butterfly centrifuge. Background Technology

[0002] Disc separators are precision equipment that separate mixtures by using the centrifugal force field generated by the high-speed rotation of a drum. They are widely used in industries such as chemical, pharmaceutical, and food processing.

[0003] Traditional centrifuge slag discharge methods are mostly "full discharge," meaning that all the solid material and some liquid accumulated in the drum are discharged at once. This method has a large impact force, which can cause instantaneous vibration and speed fluctuations in the equipment, affecting the separation effect. In addition, some clarified liquid is carried away during slag discharge, resulting in material loss, and the feeding must be interrupted, reducing the continuity and efficiency of production. Although some existing technologies attempt partial slag discharge, their control mechanisms are simple, lack precision, and are difficult to adjust accurately according to the solid content of the material, resulting in poor applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a disc centrifuge that solves the problem of current centrifuges' "full discharge" method, which involves discharging all solid material and some liquid accumulated in the drum at once. This method generates significant impact, causing instantaneous vibration and speed fluctuations in the equipment, affecting separation efficiency. Furthermore, discharge carries away some clarified liquid, resulting in material loss and necessitating interruption of feeding, reducing production continuity and efficiency. While some existing technologies attempt partial discharge, their control mechanisms are simple, lack precision, and are difficult to adjust accurately according to the solid content of the material, resulting in poor applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a butterfly centrifuge, including a motor, a vertical shaft mounted on the motor, a rotating drum mounted on the vertical shaft, a piston mounted inside the rotating drum, a nylon sealing ring mounted inside the rotating drum, the piston being connected to the nylon sealing ring, and a nylon valve mounted on one side inside the rotating drum.

[0006] As a preferred embodiment of this utility model, the upper part of the drum is provided with a feed inlet and the upper part of the drum is provided with a light phase outlet.

[0007] As a preferred embodiment of this utility model, a large pulley is fixedly connected to the output end of the motor, a small pulley is fixedly connected to the lower part of the vertical shaft, a belt is installed on the outer wall of the large pulley, and the inner side of the belt is connected to the small pulley.

[0008] As a preferred embodiment of this utility model, a buffer device is installed on the outer wall of the vertical shaft.

[0009] Compared with the prior art, the present invention provides a butterfly centrifuge with the following advantages: This type of disc centrifuge, when slag discharge is required, issues a command through the control system to activate the solenoid valve of the water distribution device, instantly opening the discharge channel of the operating water. The pressure in the operating water chamber drops rapidly, and under the action of the static pressure of the liquid inside the drum, the piston moves down quickly, opening the slag discharge port. At this time, the solid material deposited on the drum wall is thrown out at high speed under the action of centrifugal force, avoiding the loss of clarified liquid, improving the material yield, and allowing slag discharge without interrupting the feeding, greatly improving the continuity of production and processing efficiency.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example 1 Please see Figure 1-2 In this embodiment: a butterfly centrifuge includes a motor 1, a vertical shaft 2 mounted on the motor 1, a rotating drum 3 mounted on the vertical shaft 2, a piston 4 mounted inside the rotating drum 3, a nylon sealing ring 5 mounted inside the rotating drum 3, the piston 4 being connected to the nylon sealing ring 5, and a nylon valve 7 mounted on one side inside the rotating drum 3; a feed inlet 8 is provided at the top of the rotating drum 3, and a light phase outlet 9 is provided at the top of the rotating drum 3; In this embodiment, the material enters the distributor through the feed pipe from the upper feed inlet 8 and is then distributed to the disc group for separation. Solid particles move along the discs towards the wall of the drum 3 and are discharged from the sludge outlet during slag removal. The clear liquid phase moves along the discs towards the center of the drum 3 and enters the clear liquid phase pump chamber. It is then discharged from the machine through the clear liquid phase outlet by the clear liquid phase centrifugal pump. When slag removal is required, valve V1 is opened, filling the bottom of piston 4 with water. Due to centrifugal force, the water at the bottom of piston 4 generates a huge hydraulic pressure F2 on piston 4, which is greater than the pressure generated by the material inside the drum. The hydraulic pressure F1 is such that piston 4 is supported, pressing against the nylon sealing ring 5, ensuring separation within the drum 3 under sealed conditions. Valve core 6 uses its own centrifugal force F to prevent leakage from the nylon valve 7. The feed valve opens, and the separating liquid continuously enters the drum 3 for separation. Solid particles are separated from the separating liquid and accumulate on the wall of the drum 3. The clear liquid phase is discharged by the centrifugal pump. When valve V2 is opened, the cavity between valve core 6 and the valve body is filled with slag discharge water. The resulting centrifugal force F3 exceeds the centrifugal force F of valve core 6, causing valve core 6 to... As the piston moves downwards, nylon valve 7 opens, discharging the water at the bottom of piston 4. The hydraulic pressure F2 gradually decreases, and part of the discharge water is discharged from drum 3 through the drain hole, while the other part fills the cavity between valve core 6 and valve body. The water at the bottom of piston 4 is gradually emptied, and hydraulic pressure F2 gradually becomes less than hydraulic pressure F1. Under the action of hydraulic pressure F1, piston 4 moves downwards, and drum 3 discharges slag. Solid particles are discharged from drum 3 through the slag discharge groove on the drum wall. Valve V2 is closed, and the discharge water in the cavity between valve core 6 and valve body flows through the drain hole. As the discharge gradually occurs, the centrifugal force F3 gradually decreases. The centrifugal force F of valve core 6 is greater than the centrifugal force F3, so valve core 6 moves outward and closes nylon valve 7. At the same time, operating water gradually fills the bottom of piston 4 through the sealed water channel, and the hydraulic pressure F2 gradually increases, closing the separation space above piston 4. When the hydraulic pressure F2 exceeds the hydraulic pressure F1 generated by the material in the inner cavity of drum 3, piston 4 returns to the closed position. Both the upper and lower chambers of piston 4 are filled with liquid, and the interface position returns to normal working state, thus ending the entire slag discharge process.

[0014] Furthermore, a large pulley 10 is fixedly connected to the output end of the motor 1, and a small pulley 11 is fixedly connected to the lower part of the vertical shaft 2. A belt 12 is installed on the outer wall of the large pulley 10, and the inner side of the belt 12 is connected to the small pulley 11. The motor 1 starts the large pulley 10 to rotate, which in turn drives the belt 12 connected to it to move. The belt 12 drives the small pulley 11 to rotate, and then transmits the rotation to the vertical shaft 2 to drive the drum 3 to rotate.

[0015] Preferably, a buffer device 13 is installed on the outer wall of the vertical shaft 2; In order to reduce wear and reduce the impact of drum 3 vibration on the whole machine, a buffer support structure is adopted in vertical shaft 2.

[0016] The working principle and usage process of this utility model: The material enters the distributor through the feed pipe from the upper feed port 8 and is then distributed to the disc group for separation. Solid particles move along the discs towards the wall of the rotating drum 3 and are discharged from the sludge outlet during sludge discharge. The clear liquid phase moves along the discs towards the center of the rotating drum 3 and enters the clear liquid phase pump chamber. It is then discharged from the machine through the clear liquid phase outlet by the clear liquid phase centrifugal pump. When sludge discharge is required, valve V1 is opened, filling the bottom of piston 4 with water. Due to the centrifugal force, the water at the bottom of piston 4 generates a huge hydraulic pressure F2 on piston 4, which is greater than the rotational pressure. The hydraulic pressure F1 generated by the material inside the drum supports piston 4, which in turn holds the nylon sealing ring 5, ensuring separation within the drum 3 under sealed conditions. Valve core 6 uses its own centrifugal force F to prevent leakage from the nylon valve 7. When the feed valve opens, the separating liquid continuously enters the drum 3 for separation. Solid particles are separated from the separating liquid and accumulate on the wall of the drum 3. The clear liquid phase is discharged by a centrifugal pump. When valve V2 is opened, the cavity between valve core 6 and the valve body is filled with slag discharge water, generating a centrifugal force F3 that exceeds the centrifugal force F of valve core 6. As valve core 6 moves inward, nylon valve 7 opens, and the water at the bottom of piston 4 is discharged. Hydraulic pressure F2 gradually decreases. Part of the discharge water is discharged from drum 3 through the drain hole, while the other part fills the cavity between valve core 6 and valve body. The water at the bottom of piston 4 is gradually emptied, and hydraulic pressure F2 gradually becomes less than hydraulic pressure F1. Under the action of hydraulic pressure F1, piston 4 moves downward, and drum 3 discharges slag. Solid particles are discharged from drum 3 through the slag discharge groove on the drum wall. Valve V2 is closed, and the slag discharge water in the cavity between valve core 6 and valve body flows... As water is gradually discharged through the drain hole, the centrifugal force F3 gradually decreases. The centrifugal force F of valve core 6 is greater than the centrifugal force F3, so valve core 6 moves outward and closes nylon valve 7. At the same time, operating water gradually fills the bottom of piston 4 through the sealed water channel, and the hydraulic pressure F2 gradually increases, closing the separation space above piston 4. When the hydraulic pressure F2 exceeds the hydraulic pressure F1 generated by the material in the inner cavity of drum 3, piston 4 returns to the closed position. Both the upper and lower chambers of piston 4 are filled with liquid, and the interface position returns to normal working state, thus ending the entire slag discharge process.
