Description

Technical Field

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

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquids and solid particles or liquids and liquids.

[0003] Centrifuges are commonly used for solid-liquid separation operations and are widely used in industries such as pharmaceuticals, chemicals, and food. For example, during the brewing process of alcoholic beverages, distiller's grains are produced. As a direct byproduct of the brewing process, distiller's grains not only contain a certain proportion of grains, which can save on the concentrate feed for cattle, but also contain a variety of trace elements, vitamins, yeast, etc., and are also high in lysine, methionine, and tryptophan. When preparing distiller's grains from the lees liquid, a centrifuge is needed to separate the water and alcohol from the lees liquid.

[0004] However, in the process of solid-liquid separation, if the internal pores of existing centrifuges are not cleaned in time, they can easily become clogged, which will affect the subsequent solid-liquid separation process.

[0005] Therefore, it is essential to design a centrifuge with strong practicality. Summary of the Invention

[0006] The purpose of this invention is to provide a centrifuge to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a centrifuge, comprising: case; A centrifugal assembly is disposed within a housing, and the centrifugal assembly is connected to the inner wall of the housing; The reciprocating component is connected to the centrifugal component. Cleaning components are connected to the reciprocating components.

[0008] According to the above technical solution, a drain groove is provided at the bottom of the inner wall of the shell, and a drain pipe is connected to the bottom of the shell. The drain pipe is connected to the drain groove, and the drain groove and the drain pipe facilitate the discharge of the separated liquid.

[0009] According to the above technical solution, a bracket is fixedly installed on the bottom surface of the shell. The number of brackets is four, and the four brackets are evenly distributed on the bottom surface of the shell. The four brackets installed on the bottom surface of the shell can provide stable support for the entire shell.

[0010] According to the above technical solution, the centrifuge assembly includes: The motor is housed inside the housing, with its bottom fixedly installed to the bottom of the inner wall of the housing, and a connecting shaft fixedly installed at the output end of the motor. A porous conical cylinder is fixedly sleeved on the outer wall of the connecting shaft. The porous outer wall of the cylinder is made of rubber. A motor can be installed to drive the connecting shaft to rotate the porous conical cylinder, generating centrifugal force to achieve solid-liquid separation.

[0011] According to the above technical solution, a conical hopper is provided above the porous conical cylinder, and the outer wall of the upper end of the conical hopper is fixedly installed with the inner wall of the shell. An auxiliary hopper is provided below the porous conical cylinder, and the auxiliary hopper is movably sleeved on the outer wall of the connecting shaft. The bottom of the auxiliary hopper is fixedly installed with the bottom of the inner wall of the shell. The conical hopper facilitates the concentration of solid and liquid entering the porous conical cylinder, and the auxiliary hopper prevents the liquid from contacting the motor and facilitates the discharge of liquid.

[0012] According to the above technical solution, the centrifuge assembly further includes: An outer annular plate is slidably disposed on the inner wall of a large annular groove opened in the inner wall of the shell, and the inner wall of the annular plate is in contact with the outer wall of the upper end of the porous conical cylinder. A small annular groove is opened on the inner wall of the outer annular plate, and an inner annular block is slidably disposed on the inner wall of the small annular groove. Multiple equally spaced obstruction blocks are fixedly installed on the inner wall of the small annular groove. The inner annular block is fixedly installed on the outer wall of the upper end of the porous conical cylinder. The first spring is installed inside the large annular groove. The top end of the first spring is fixedly installed to the bottom surface of the outer annular plate, and the bottom end of the first spring is fixedly installed to the bottom of the inner wall of the large annular groove. The inner annular block and the obstruction block can squeeze the multi-hole conical cylinder as it rotates, thereby deforming the multi-hole conical cylinder. Finally, with the cooperation of the first spring, the deformed part of the multi-hole conical cylinder can vibrate, thus preventing blockage and affecting the separation effect.

[0013] According to the above technical solution, the reciprocating component includes: A conical cylinder is disposed inside a porous conical cylinder. A shrinkable elastic rubber ring is fixedly installed at the bottom of the cylindrical cylinder. An I-shaped annular plate is fixedly installed at the bottom of the shrinkable elastic rubber ring. The I-shaped annular plate is slidably disposed with an inner T-shaped annular groove opened at the bottom of the inner wall of the porous conical cylinder. The bottom surface of the first wedge-shaped column is fixedly installed with the top surface of the connecting shaft. The top surface of the first wedge-shaped column is in contact with the second wedge-shaped column, and the top surface of the second wedge-shaped column is fixedly installed with the top surface of the inner wall of the conical cylinder. The surfaces of the first and second wedges that come into contact with each other are both inclined. By making the surfaces of the first and second wedges inclined, the second wedge can be squeezed when the first wedge rotates, so that the second wedge has an upward tendency.

[0014] According to the above technical solution, the size of the inner T-shaped annular groove is larger than the size of the lower end of the I-shaped annular plate, so as to avoid the T-shaped annular groove from being stuck with the I-shaped annular plate and to avoid large-scale rotation.

[0015] According to the above technical solution, the cleaning component includes: The connecting rod has a slidable connection between its outer wall and the outer wall of the conical cylinder, and a second spring is fixedly installed between the connecting rod and the inner wall of the connection. A rubber body is disposed between the first wedge-shaped post and the connecting rod. One end of the rubber body is fixedly installed to the outer wall of the first wedge-shaped post, and the other end of the rubber body is fixedly installed to one end of the connecting rod. The cleaning plate is fixedly installed on the side and at the other end of the connecting rod.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention uses a motor to drive the connecting shaft to rotate a porous conical cylinder. The rotation of the porous conical cylinder generates centrifugal force, which throws the liquid out from the pores of the porous conical cylinder, thus achieving solid-liquid separation.

[0017] 2. In this invention, the inner annular block, the obstruction block, and the first spring can achieve deformation and vibration of the porous conical cylinder under the operation of the centrifugal assembly, thus avoiding clogging of the porous parts of the porous conical cylinder and affecting the centrifugal filtration effect.

[0018] 3. In this invention, by setting the first wedge and the second wedge, especially by setting the contact surfaces of the first wedge and the second wedge as inclined surfaces, and then by setting the elastic rubber ring, the conical cylinder can be made to move up and down in a reciprocating motion under the rotation of the connecting shaft, which enhances the cleaning force of the cleaning plate on the inner wall of the porous conical cylinder.

[0019] 4. In this invention, the rubber body can drive the connecting rod to move back and forth during the reciprocating motion of the second wedge column. The second spring can enhance the vibration performance of the cleaning plate and prevent impurities from adhering to the surface of the cleaning plate, thus affecting the cleaning effect of the cleaning plate.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0023] Please see Figure 1-7 The present invention provides a technical solution: a centrifuge, comprising: The shell 1 has a drainage groove 8 at the bottom of its inner wall, and a drainage pipe 3 is connected to the bottom of the shell 1. The drainage pipe 3 is connected to the drainage groove 8. The drainage groove 8 and the drainage pipe 3 facilitate the discharge of the separated liquid. Four supports 2 are fixedly installed on the bottom surface of the shell 1. The four supports 2 are evenly distributed on the bottom surface of the shell 1. The four supports 2 installed on the bottom surface of the shell 1 can provide stable support for the entire shell 1. Centrifugal assembly 71 is disposed inside housing 1, and the centrifugal assembly 71 is connected to the inner wall of housing 1; The reciprocating component 9 is connected to the centrifugal component 71. The cleaning component 10 is connected to the reciprocating component 9.

[0024] Centrifuge assembly 7 includes: Motor 71 is disposed inside housing 1. The bottom of motor 71 is fixedly installed to the bottom of the inner wall of housing 1. A connecting shaft 72 is fixedly installed at the output end of motor 71. The porous conical cylinder 73 is fixedly sleeved on the outer wall of the connecting shaft 72. The porous outer wall of the porous conical cylinder 73 is made of rubber, which makes it easy to deform when the porous conical cylinder 73 is subjected to external force.

[0025] In the specific implementation process, starting the motor 71 can make the connecting shaft 72 rotate. Since the porous conical cylinder 73 is installed on the outer wall of the connecting shaft 72, the rotation of the connecting shaft 72 can make the porous conical cylinder 73 rotate together, forming centrifugal force and achieving the purpose of solid-liquid separation.

[0026] In this embodiment, a conical hopper 4 is provided above the porous conical cylinder 73. The outer wall of the upper end of the conical hopper 4 is fixedly installed with the inner wall of the housing 1. An auxiliary hopper 6 is provided below the porous conical cylinder 73. The auxiliary hopper 6 is movably sleeved on the outer wall of the connecting shaft 72, and the bottom of the auxiliary hopper 6 is fixedly installed with the bottom of the inner wall of the housing 1. The conical hopper 4 facilitates the concentration of solid and liquid entering the porous conical cylinder 73. The auxiliary hopper 6 prevents the liquid from contacting the motor 71 and facilitates the discharge of the liquid.

[0027] Furthermore, the centrifuge assembly 7 also includes: The outer annular plate 74 is slidably disposed with the inner wall of the large annular groove 5 opened in the inner wall of the housing 1, and the inner wall of the annular plate 74 is in contact with the outer wall of the upper end of the porous conical cylinder 73. The inner wall of the outer annular plate 74 is provided with a small annular groove 76, and an inner annular block 77 is slidably disposed on the inner wall of the small annular groove 76. Multiple equally spaced obstruction blocks 78 are fixedly installed on the inner wall of the small annular groove 76. The inner annular block 77 is fixedly installed with the outer wall of the upper end of the porous conical cylinder 73. A first spring 75 is disposed in the large annular groove 5. The top end of the first spring 75 is fixedly installed to the bottom surface of the outer annular plate 74, and the bottom end of the first spring 75 is fixedly installed to the bottom of the inner wall of the large annular groove 76.

[0028] When the porous conical cylinder 73 rotates, the inner annular block 77 can rotate along with it. During the rotation of the inner annular block 77, it will be squeezed against the obstruction block 78. At this time, the rubber material of the porous conical cylinder 73 will be deformed in some places. Then, under the action of the first spring 75, the vibration performance of the deformed part of the porous conical cylinder 73 can be increased to prevent it from being blocked and to shake off solid impurities. Example 2

[0029] Based on the above implementation scheme, the reciprocating component 9 includes: A conical cylinder 91 is disposed inside a porous conical cylinder 73. A shrinkable elastic rubber ring 92 is fixedly installed at the bottom of the cylindrical cylinder 91. An I-shaped annular plate 94 is fixedly installed at the bottom of the shrinkable elastic rubber ring 92. The I-shaped annular plate 94 is slidably disposed with an inner T-shaped annular groove 93 opened at the bottom of the inner wall of the porous conical cylinder 73. Here, the size of the inner T-shaped annular groove 93 is larger than the size of the lower end of the I-shaped annular plate 94, so as to avoid the T-shaped annular groove 93 and the I-shaped annular plate 94 from being stuck together and to avoid large-scale rotation. The bottom surface of the first wedge post 95 is fixedly installed with the top surface of the connecting shaft 72, and the top surface of the first wedge post 95 is in contact with the second wedge post 96, and the top of the second wedge post 96 is fixedly installed with the top of the inner wall of the conical cylinder 91. The surfaces of the first wedge 95 and the second wedge 96 that come into contact with each other are both inclined surfaces. This allows for compression between the first wedge 95 and the second wedge 96 during rotation, giving the second wedge 96 an upward tendency.

[0030] In the specific implementation process, the first wedge post 95 can rotate during the rotation of the connecting shaft 72. Since the contact surfaces of the first wedge post 95 and the second wedge post 96 are set as inclined surfaces, the rotation of the first wedge post 95 can squeeze the second wedge post 96, causing the second wedge post 96 to drive the conical cylinder 91 to move upward. Due to the provided shrinkage elastic rubber ring 92, the conical cylinder 91 can move up and down reciprocally. The up and down reciprocating motion of the conical cylinder 91 can enable the cleaning component 10 to clean the inner wall of the porous conical cylinder 73. Example 3

[0031] Based on the above implementation scheme, the cleaning component 10 includes: The connecting rod 1002 is slidably disposed between its outer wall and the communication port 1003 opened on the outer wall of the conical cylinder 91, and a second spring 1004 is fixedly installed between the connecting rod 1002 and the inner wall of the communication port 1003. A rubber body 1001 is disposed between the first wedge-shaped post 95 and the connecting rod 1002. One end of the rubber body 1001 is fixedly installed to the outer wall of the first wedge-shaped post 95, and the other end of the rubber body 1001 is fixedly installed to one end of the connecting rod 1002. The cleaning plate 1005 is fixedly installed on the side and at the other end of the connecting rod 1002.

[0032] In the specific implementation process, as the second wedge column 96 moves upward, the rubber body 1001 can move upward together, and then squeeze the connecting rod 1002, causing the connecting rod 1002 to drive the cleaning plate 1005 to move and contact the inner wall of the porous conical cylinder 73 to achieve the cleaning work. Under the action of the second spring 1004, the connecting rod 1002 can reciprocate, causing the impurities on the cleaning plate 1005 to fall off, avoiding affecting the subsequent cleaning effect.

[0033] Working principle: The solid and liquid to be separated are poured into the porous conical cylinder 73. Before this, the motor 71 is started to rotate the connecting shaft 72. The rotation of the connecting shaft 72 causes the porous conical cylinder 73, which is mounted on the outer wall of the connecting shaft 72, to rotate. The rotation of the porous conical cylinder 73 generates centrifugal force, which finally throws the liquid out, achieving the purpose of solid-liquid separation. At the same time, the rotation of the porous conical cylinder 73 causes the inner annular block 77 to rotate within the large annular groove 5 opened in the outer annular plate 74. Due to the obstruction block 78, the liquid is separated from the liquid. The rotation of the inner annular block 77 generates a compressive force, causing deformation of the rubber portion of the porous conical cylinder 73. The first spring 75 then vibrates the rubber portion of the porous conical cylinder 73, preventing blockage of the porous parts and ensuring efficient solid-liquid separation. The rotation of the connecting shaft 72 causes the first wedge-shaped column 95 to rotate. Since the first wedge-shaped column 95 contacts the second wedge-shaped column 96, its rotation compresses the second wedge-shaped column 96. The second wedge-shaped column 96 presses upward against the conical cylinder 91. Due to the provided elastic rubber ring 92, the conical cylinder 91 can reciprocate up and down. This reciprocating motion of the conical cylinder 91 allows the cleaning plate 1005 to clean the inner wall of the porous conical cylinder 73, removing impurities and enhancing the cleaning force. During the up-and-down movement of the second wedge-shaped column 96, the rubber body 1001 mounted on its surface can move. The colloid 1001, with its upward tendency, can squeeze the connecting rod 1002, ultimately causing the connecting rod 1002 to move the cleaning plate 1005, which then contacts the inner wall of the porous conical cylinder 73, achieving the cleaning purpose. The second spring 1004 enables the connecting rod 1002 to reciprocate, which in turn causes the cleaning plate 1005 to vibrate. This vibration can dislodge impurities from the cleaning plate 1005, preventing subsequent cleaning issues.
