DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0023] See also Figure 1-7 The present invention provides a technical solution: a centrifuge, comprising: The shell 1 has a row groove 8 at the bottom of the inner wall of the shell 1, and a row pipe 3 is connected to the bottom of the shell 1, and the row pipe 3 is connected to the row groove 8. The row groove 8 and the row pipe 3 can facilitate the discharge of the separated liquid. The bottom surface of the shell 1 is fixedly installed with a bracket 2. The number of the brackets 2 is four, and the four brackets 2 are evenly spaced on the bottom surface of the shell 1. The four brackets 2 installed on the bottom surface of the shell 1 can play a role in firmly supporting the entire shell 1; The centrifugal assembly 71 is disposed in the housing 1, and the centrifugal assembly 71 is connected to the inner wall of the housing 1; The up and down reciprocating assembly 9 is connected to the centrifugal assembly 71; The cleaning assembly 10 is connected to the up and down reciprocating assembly 9.

[0024] The centrifugal assembly 7 comprises: The motor 71 is disposed in the housing 1. The bottom of the motor 71 is fixedly mounted to the bottom of the inner wall of the housing 1. The output end of the motor 71 is fixedly mounted with a connecting shaft 72. The porous conical cylinder 73 is fixedly sleeved on the outer wall of the connecting shaft 72. The porous outer walls of the porous conical cylinder 73 are all made of rubber material, so that the porous conical cylinder 73 can be easily deformed when subjected to external force.

[0025] In the specific implementation process, the connecting shaft 72 can be rotated by starting the motor 71. Since the porous conical cylinder 73 is installed on the outer wall of the connecting shaft 72, the porous conical cylinder 73 can be rotated together when the connecting shaft 72 rotates, forming centrifugal force to achieve the purpose of solid-liquid separation.

[0026] In this embodiment, a conical bucket 4 is arranged above the porous conical cylinder 73, and the outer wall of the upper end of the conical bucket 4 is fixedly installed on the inner wall of the shell 1. An auxiliary bucket 6 is arranged below the porous conical cylinder 73. The auxiliary bucket 6 is movably sleeved on the outer wall of the connecting shaft 72, and the bottom of the auxiliary bucket 6 is fixedly installed on the bottom of the inner wall of the shell 1. The conical bucket 4 is arranged to facilitate the concentrated entry of solid and liquid into the porous conical cylinder 73. The auxiliary bucket 6 is arranged to prevent the liquid from contacting the motor 71 and facilitate the discharge of the liquid.

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

[0028] As 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 with the obstruction block 78, at which time the rubber material part of the porous conical cylinder 73 will be deformed. 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 avoid its blockage and shake off the solid impurities. Example 2

[0029] On the basis of the above embodiment, the up and down reciprocating assembly 9 comprises: The conical cylinder 91 is arranged in the porous conical cylinder 73. A shrinking 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 shrinking elastic rubber ring 92. The I-shaped annular plate 94 is slidably arranged 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 clamped and the large-scale rotation phenomenon is avoided; The first wedge-shaped column 95 has a bottom surface fixedly mounted on the top of the connecting shaft 72, and the top surface of the first wedge-shaped column 95 is contacted with a second wedge-shaped column 96, and the top of the second wedge-shaped column 96 is fixedly mounted on the top of the inner wall of the conical cylinder 91; The surfaces where the first wedge-shaped column 95 and the second wedge-shaped column 96 contact each other are both inclined surfaces, so that during the rotation of the first wedge-shaped column 95 , extrusion can be formed between the first wedge-shaped column 95 and the second wedge-shaped column 96 , so that the second wedge-shaped column 96 has a tendency to move upward.

[0030] In the specific implementation process, the first wedge column 95 can be rotated during the rotation of the connecting shaft 72. Since the contact surface between the first wedge column 95 and the second wedge column 96 is set as an inclined surface, the second wedge column 96 can be squeezed when the first wedge column 95 rotates, so that the second wedge column 96 drives the conical cylinder 91 to move upward. Due to the setting of the shrinkage elastic rubber ring 92, the conical cylinder 91 can be reciprocated up and down. When the conical cylinder 91 reciprocates up and down, the cleaning component 10 can clean the inner wall of the porous conical cylinder 73. Example 3

[0031] Based on the above embodiment, the cleaning component 10 includes: The connecting rod 1002 is slidably arranged with its outer wall and the communication port 1003 provided 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; The rubber body 1001 is disposed between the first wedge-shaped column 95 and the connecting rod 1002, one end of the rubber body 1001 is fixedly mounted to the outer wall of the first wedge-shaped column 95, and the other end of the rubber body 1001 is fixedly mounted to one end of the connecting rod 1002; The cleaning plate 1005 is fixedly mounted on its side with the other end of the connecting rod 1002 .

[0032] In the specific implementation process, as the second wedge-shaped column 96 moves upward, the rubber body 1001 can move upward together, and then squeeze the connecting rod 1002, so that the connecting rod 1002 drives the cleaning plate 1005 to move and contact the inner wall of the porous conical cylinder 73 to achieve cleaning. Under the action of the second spring 1004, the connecting rod 1002 can be reciprocated to vibrate, so that impurities on the cleaning plate 1005 can be shaken off to avoid affecting the subsequent cleaning effect.

[0033] Working principle: Pour the solid and liquid to be separated into the porous conical cylinder 73. Before that, start the motor 71 to rotate the connecting shaft 72. The rotation of the connecting shaft 72 can make the porous conical cylinder 73 installed on the outer wall of the connecting shaft 72 rotate. The rotation of the porous conical cylinder 73 can form centrifugal force, and finally the liquid can be thrown out to achieve the purpose of solid-liquid separation. At the same time, the rotation of the porous conical cylinder 73 can make the inner annular block 77 rotate in the large annular groove 5 opened in the outer annular plate 74. Due to the setting of the obstruction block 78, The inner annular block 77 rotates to form an extrusion force, causing the rubber material part of the porous conical cylinder 73 to deform, and then the first spring 75 can achieve the vibration of the rubber material part of the porous conical cylinder 73, and finally, the porous part of the porous conical cylinder 73 can be prevented from being blocked, thereby preventing the subsequent solid-liquid separation efficiency from being affected. The first wedge column 95 can be rotated when the connecting shaft 72 rotates. Since the first wedge column 95 is in contact with the second wedge column 96, the second wedge column 96 can be squeezed when the first wedge column 95 rotates, and The second wedge-shaped column 96 presses the conical cylinder 91 upward. Due to the shrinkage elastic rubber ring 92, the conical cylinder 91 can reciprocate up and down. Under the reciprocating up and down movement of the conical cylinder 91, the cleaning plate 1005 can clean the inner wall of the porous conical cylinder 73 up and down, and remove the impurities on the inner wall of the porous conical cylinder 73, thereby strengthening the cleaning force on the inner wall of the porous conical cylinder 73. During the up and down movement of the second wedge-shaped column 96, the rubber body 1001 installed on the surface of the second wedge-shaped column 96 can be driven to move. The colloid 1001 has an upward movement tendency and can squeeze the connecting rod 1002, and finally the connecting rod 1002 drives the cleaning plate 1005 to move, and is in contact with the inner wall of the porous conical cylinder 73 to achieve the cleaning purpose. Since the second spring 1004 is set, the reciprocating vibration of the connecting rod 1002 can be realized, and the cleaning plate 1005 can be vibrated under the reciprocating vibration of the connecting rod 1002. Under the vibration, impurities attached to the cleaning plate 1005 can be shaken off, avoiding the cleaning effect of the cleaning plate 1005 in the later stage.
