Description

Technical Field

[0001] This invention belongs to the field of centrifuge technology, and specifically relates to a high-temperature centrifuge. Background Technology

[0002] High-temperature centrifuges are a special type of centrifuge. During operation, their internal temperature needs to reach hundreds or even thousands of degrees Celsius to achieve solid-liquid separation of materials such as coal gangue, fly ash, and waste lithium battery raw materials. Due to the extremely high internal temperature, these centrifuges present problems such as difficult loading and unloading operations, long downtime during loading and unloading, low efficiency, and high energy consumption, which urgently need to be improved. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention provides a high-temperature centrifuge that can perform loading and unloading without cooling. It can open only a small loading and unloading port to unload and load materials into the compartments separately, avoiding the need to open the entire cover, effectively reducing heat loss in the centrifuge chamber, shortening loading and unloading time, and improving efficiency.

[0004] The technical solution adopted in this invention is as follows:

[0005] A high-temperature centrifuge, comprising:

[0006] Base;

[0007] A housing is mounted on the base, the housing contains a centrifuge chamber, and has an opening at the top;

[0008] A cover, which can be opened and closed, is provided at the opening of the housing and can seal the opening of the housing.

[0009] The main shaft is rotatably and sealed through the bottom of the housing via a bearing assembly, with its upper end located inside the centrifuge chamber and its lower end located outside the housing;

[0010] A rotating drum is located inside the centrifuge chamber and is coaxially connected to the upper end of the main shaft.

[0011] A drive assembly is connected to the lower end of the main shaft to drive the main shaft to rotate;

[0012] The material frame assembly is detachably mounted on the rotating drum;

[0013] in,

[0014] The material frame assembly includes a material frame and several material frames. The material frame is detachably and positionably installed inside the drum. Several partition frames are evenly distributed circumferentially inside the material frame, and the material frames are adapted to be placed inside the partition frames.

[0015] The cover is provided with a loading and unloading port, which corresponds to the position of the partition frame and is adapted to the size of the material frame. The material frame can pass vertically through the loading and unloading port for loading and unloading. The loading and unloading port is provided with an openable and closable loading and unloading cover.

[0016] In one embodiment of this application, the drum is provided with a first positioning part, and the material frame is provided with a second positioning part. The material frame is positioned and installed inside the drum by the vertical cooperation of the first positioning part and the second positioning part.

[0017] The sidewall of the drum is provided with several first liquid outlet holes;

[0018] The material frame has several second liquid outlet holes on its outer side facing the side wall of the drum, and several vertical protrusions on its outer side.

[0019] When this high-temperature centrifuge is in use, the material to be centrifuged is a solid material. After being heated in the centrifuge chamber, part of the material is liquefied. Then, under the action of centrifugal force, it is centrifuged and thrown out through the first liquid outlet and the second liquid outlet. The convex ridge is set to create a gap between the outer side of the material frame and the side wall of the drum, so as to avoid sticking and facilitate dehydration.

[0020] In one embodiment of this application, the cover is a heat-insulating cover; the shell is provided with a heat-insulating layer; a heating component is provided on the inner wall of the shell, and the heating component includes an electric heating wire.

[0021] In one embodiment of this application, the housing includes a separately configured heat-insulating base and a heat-insulating sidewall, which are flexibly and sealed together.

[0022] The base includes a first base and a second base that are independent of each other. The heat-insulating base is disposed on the first base, and the heat-insulating sidewall is disposed on the second base.

[0023] The first and second bases support the insulation base and insulation sidewall of the casing respectively, preventing the vibration generated by the main shaft during high-speed operation of the centrifuge from affecting the insulation sidewall and heating components, and effectively extending the service life of the heating components.

[0030] The drum and the material frame are hollowed out along the axial direction in the middle, and the hollowed-out part corresponds to the air outlet of the circulating fan.

[0031] The upper side wall of the liquid-blocking cylinder is provided with a circulating air inlet;

[0032] When the circulating fan is running, it draws in the hot air between the side wall of the housing and the outside of the baffle cylinder, and sends the air downward through the hollowed-out part in the middle of the drum and the material frame, into the lower part of the centrifugal chamber, and then upward into the upper part of the centrifugal chamber from the inner side of the baffle cylinder and the outer side of the drum and the outer side of the baffle cylinder and the side wall of the housing, forming a hot air circulation.

[0033] In one embodiment of this application, the driving component includes a centrifugal driving component and a material frame positioning driving component;

[0034] The centrifugal drive assembly includes a centrifugal drive motor and a first transmission component. The output end of the centrifugal drive motor is connected to the lower end of the main shaft via the first transmission component, and is used to drive the main shaft and the drum to rotate.

[0035] The material frame positioning drive assembly includes an indexing plate, a detector, a positioning drive component, and a second transmission component. The indexing plate is coaxially fixedly installed on the lower part of the main shaft, and the number of equal divisions and the installation position of the indexing plate correspond to the partition frame of the material frame. The detector is installed on the bottom of the housing and corresponds to the indexing plate. The output end of the positioning drive component is connected to the main shaft or the first transmission component via the second transmission component.

[0036] In one embodiment of this application, the first transmission component includes a first pulley mounted on the main shaft, a second pulley mounted on the output end of the centrifugal drive motor, and a first belt connecting the first pulley and the second pulley;

[0037] The positioning drive component includes a hand crank, a first bevel gear, a second bevel gear, a worm, a worm wheel, and a lifting connecting rod; one end of the hand crank is a handle, and the other end is provided with a first bevel gear. The second bevel gear is coaxially fixed on the worm. The worm wheel is circumferentially limited and sleeved on the lifting connecting rod. The first bevel gear meshes with the second bevel gear, and the worm meshes with the worm wheel.

[0038] The second transmission component includes a third pulley, a fourth pulley, and a second belt; the third pulley engages with the end of the lifting connecting rod, and the axial movement of the lifting connecting rod allows it to engage with the third pulley for circumferential locking or unlocking; the fourth pulley is coaxially connected to the second pulley, and the second belt connects the third pulley and the fourth pulley.

[0039] In one embodiment of this application, the bearing assembly includes a bearing housing, a bearing, an upper bearing housing cover, and a lower bearing housing cover; the bearing housing is partially embedded in the housing, and the main shaft is rotatably mounted in the bearing housing via the bearing; the upper bearing housing cover and the lower bearing housing cover are respectively installed at the upper and lower ends of the bearing housing;

[0040] The bearing housing has a cylindrical first cooling chamber with a spiral guide vane inside; the upper bearing housing cover has a second cooling chamber; the main shaft has an axially oriented third cooling chamber, and the lower end of the main shaft is connected to a coolant inlet / outlet connector, with the inlet pipe of the coolant inlet / outlet connector extending into the top of the third cooling chamber.

[0041] In one embodiment of this application, a hoisting mechanism is also included, which is adapted to the loading and unloading port and can load and unload the material frame from the loading and unloading port.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] 1. The high-temperature centrifuge of the present invention sets the material frame into several partitioned frames, and provides several partitioned material frames for loading materials. The cover is provided with loading and unloading ports that are adapted to the position of the partitioned frames and the size of the material frames. After centrifugation, it is not necessary to open the entire cover. The partitioned material frames can be taken out and loaded through the loading and unloading ports, which can realize rapid unloading and loading operations. It can effectively reduce the heat loss in the centrifuge chamber, eliminate the need to wait for cooling before loading and unloading operations, shorten the processing time, reduce energy consumption, improve work efficiency, and make it safer.

[0044] 2. By combining the configuration of a circulating fan, a rotating drum, a hollowed-out section in the middle of the material frame, a suspended lower part of the liquid baffle, and a circulating air vent at the top, the heat generated by the heating components on the inner wall of the shell can be drawn into other parts of the centrifugal chamber, forming a heat circulation loop from the outside to the inside and from the bottom to the top within the centrifugal chamber. This ensures that the heat generated by the heating components is evenly distributed within the centrifugal chamber, accelerating the heating of the material and resulting in more uniform heating and higher thermal energy utilization.

[0045] 3. Set up a centrifugal drive component and a material frame positioning drive component, respectively to drive high-speed centrifugation and drive the material frame's partition frame to correspond with the loading and unloading port, so as to facilitate the accurate removal and placement of the material frame.

[0046] 4. The bearing assembly is equipped with a first cooling chamber, a second cooling chamber, and a third cooling chamber. By connecting the cooling medium, the spindle and bearing assembly can be kept at a stable operating temperature, avoiding problems such as unstable centrifugal operation and accelerated wear of the spindle and bearing assembly due to overheating. This ensures stable operation of the centrifuge and extends its service life. Attached Figure Description

[0070] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention.

[0071] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0072] like Figures 1 to 8 As shown, an embodiment of the present invention provides a high-temperature centrifuge, which includes a base 1, a shell 2, a cover 20, a main shaft 3, a rotating drum 41, a drive assembly, and a material frame assembly, etc.

[0073] The base 1 is used for support, and the housing 2 is mounted on the base 1. The housing 2 contains a centrifuge chamber, and the top of the housing 2 has an opening. The cover 20 is adapted to the opening at the top of the housing 2, and is closable at the opening of the housing 2 to seal the opening.

[0074] The main shaft 3 is rotatably sealed and mounted on the bottom of the housing 2 via a bearing assembly, and can rotate relative to the housing 2. The upper end of the main shaft 3 is inserted into the centrifuge chamber, and the lower end is located on the outer side of the bottom of the housing 2.

[0075] The drum 41 is a cylindrical structure and is located in the centrifugal chamber of the housing 2. Its bottom is coaxially fixedly connected to the upper end of the main shaft 3. The drum 41 can be driven to rotate by the main shaft 3.

[0076] The drive assembly is located outside the housing 2 and is connected to the lower end of the main shaft 3. The drive assembly drives the main shaft 3 to rotate, thereby driving the drum 41 to rotate.

[0077] The material frame assembly is detachably mounted on the rotating drum 41 and is driven to rotate by the rotating drum 41. The material frame assembly is used to load materials so that the materials are heated and centrifugally separated in the material frame assembly.

[0078] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the material frame assembly includes a material frame 42 and several material frames 43. The material frame 42 is adapted to the rotating drum 41 and is detachably positioned inside the rotating drum 41, providing circumferential restraint. The rotation of the rotating drum 41 drives the material frame 42 to rotate synchronously. Several partition frames 421 are evenly distributed circumferentially inside the material frame 42. The material frames 43 are used to hold materials and are adapted to the partition frames 421. They can be removed or placed from the top of the partition frames 421; they are positioned within the partition frames 421 and rotate synchronously with the rotating drum 41 and the material frame 42 for centrifugal rotation.

[0079] like Figure 1 and Figure 2As shown, the cover 20 has a loading / unloading port 201, which corresponds to the position of the partition frame 421 on the material frame 42 when it is placed on the rotating drum 41. Rotation of the rotating drum 41 and the material frame 42 allows each partition frame 421 to be positioned directly below the loading / unloading port 201. Furthermore, the size of the loading / unloading port 201 is adapted to the size of the material frame 43, being slightly larger, so that the material frame 43 can pass vertically through the loading / unloading port 201 for loading and unloading. The loading / unloading port 201 is equipped with an openable and closable loading / unloading cover 202, which can seal the loading / unloading port 201.

[0080] The material frame 42 is equipped with a partition frame 421, and the material frame 43 is divided into several compartments, so that each compartment of the material frame 43 can be loaded and unloaded separately. At the same time, a small loading and unloading port 201 is opened on the cover 20 to correspond and match the partition frame 421 and the material frame 43. This allows the high-temperature centrifuge to not open the cover 20 after centrifugation, but only open the loading and unloading cover 202. The loading and unloading operations of each compartment of the material frame 43 can be carried out through the loading and unloading port 201, which can effectively reduce the heat loss in the centrifuge chamber. There is no need to wait for cooling between the loading and unloading operations, which shortens the processing time, improves the production efficiency, and makes the operation safer by only opening the loading and unloading port 201.

[0081] In one embodiment, the drum 41 is provided with a first positioning part 411, and the material frame 42 is provided with a second positioning part 422 corresponding to and adapted to the first positioning part 411. The material frame 42 is positioned and installed inside the drum 41 through the vertical cooperation of the first positioning part 411 and the second positioning part 422, and can rotate synchronously with the drum 41. This vertical cooperation facilitates the quick loading and unloading of the material frame 42. Specifically, as... Figure 4 and Figure 5 As shown, the first positioning part 411 can be a protrusion or groove provided on the upper side wall of the drum 41, and the second positioning part 422 is a groove or protrusion provided on the upper outer edge of the material frame 42. The positioning and installation of the drum 41 and the material frame 42 are achieved by the matching and engagement of the protrusion and groove in the vertical direction.

[0082] Multiple first liquid outlet holes 412 are distributed on the side wall of the drum 41; several second liquid outlet holes 431 are provided on the outer side of the material frame 43 facing the side wall of the drum 41; the material frame 42 is a frame structure without side walls. During centrifugation, the liquid thrown out of the material frame 43 is discharged from the drum 41 through the second liquid outlet holes 431 and the first liquid outlet holes 412 to achieve solid-liquid separation.

[0083] When this high-temperature centrifuge is in use, the material to be centrifuged is usually a solid material. After being heated in the centrifuge chamber, part of the material is liquefied and then centrifuged out through the first liquid outlet 412 and the second liquid outlet 431 under the action of centrifugal force.

[0084] Preferably, such as Figure 1 and Figure 6 As shown, the outer surface of the material frame 43 facing the side wall of the drum 41 is also provided with several vertical protrusions 432. The protrusions 432 are provided to create a gap between the outer surface of the material frame 43 and the side wall of the drum 41, preventing the two side walls from sticking together and facilitating liquid removal. Furthermore, the upper and lower parts of the protrusions 432 are provided with thinner beveled parts, which serve as guides to facilitate the removal and placement of the material frame 43 into the separator frame 421.

[0085] The cover 20 of this high-temperature centrifuge is a heat-insulating cover, and the shell 2 is provided with a heat-insulating layer. A heating component 211 is provided on the inner wall of the shell 2. This heating component 211 preferably includes electric heating wires evenly distributed on the inner wall of the shell 2, achieving rapid heating of the centrifuge chamber and the centrifuged material through electric heating. Furthermore, the electric heating wires of the heating component 211 are located on the inner wall of the shell 2 (rather than inside the side wall), facilitating inspection and maintenance, and resulting in higher heating efficiency.

[0086] Furthermore, such as Figures 1 to 4 As shown, the preferred housing 2 includes a separately configured heat-insulating base 22 and a heat-insulating sidewall 21, and the connection between the heat-insulating base 22 and the heat-insulating sidewall 21 is flexibly sealed through the heat-insulating layer.

[0087] The base 1 includes a first base 11 and a second base 12 that are independent of each other. The heat-insulating base 22 is disposed on the first base 11, and the heat-insulating sidewall 21 is disposed on the second base 12. Specifically, the platform of the first base 12 supports the heat-insulating base 22 at the bottom, and the column of the second base 12 passes through the platform of the first base 12. An annular platform is disposed on the platform of the first base 12 to support the heat-insulating sidewall 21, bypassing the heat-insulating base 22.

[0088] The insulation base 22 and the insulation sidewall 21 are supported by the first base 11 and the second base 12 respectively. The first base 11 and the second base 12 are relatively independent, which can effectively prevent the vibration generated by the main shaft when the centrifuge is running at high speed from affecting the insulation sidewall and the heating component, and effectively extend the service life of the heating component.

[0089] like Figure 1 and Figure 4 As shown, it also includes a liquid collection tank 221 and a liquid baffle 5.

[0090] The liquid collection tank 221 is an annular groove, which is arranged in a ring on the bottom wall of the housing 2 (i.e., on the heat preservation base 22) and is coaxial with the main shaft 3, the rotating drum 41, etc. The bottom of the liquid collection tank 221 is provided with a liquid outlet 222 connected to the outside of the housing 2 for discharging the liquid separated by centrifugation.

[0091] The liquid-retaining cylinder 5 is coaxially disposed on the outer periphery of the rotating drum 41, with a certain gap between the inner side of the liquid-retaining cylinder 5 and the rotating drum 41, and between the outer side of the liquid-retaining cylinder 5 and the side wall of the housing 2. The upper part of the rotating drum 41 is connected to the top of the housing 2, and the lower part is suspended above the liquid collection tank 221, that is, the size and installation position of the liquid-retaining cylinder 5 are adapted to the liquid collection tank 221. Specifically, on the projection surface, the annular outer edge of the liquid collection tank 221 is located outside the liquid-retaining cylinder 5 (that is, the diameter of the annular outer edge of the liquid collection tank 221 is larger than the outer diameter of the liquid-retaining cylinder 5), and the annular outer edge of the liquid collection tank 221 is higher than the lower edge of the liquid-retaining cylinder 5; at the same time, the annular inner edge of the liquid collection tank 221 is located below the rotating drum 41, and the diameter of the annular inner edge of the liquid collection tank 221 is smaller than the outer diameter of the rotating drum 42. The liquid collection tank 221 is designed to work in conjunction with the liquid baffle 5 so that the liquid thrown out by the drum 41 during centrifugation is thrown onto the liquid baffle 5 and collected and flowed downwards into the liquid collection tank 221 for collection and discharge. This effectively prevents the liquid from being thrown onto the side wall of the shell 2 and contaminating the side wall and the heating component 211, ensuring the heating efficiency and service life of the heating component 211. In addition, the centrifugal components in the centrifugal chamber are easy to clean and maintain.

[0092] Further preferred, such as Figure 1 As shown, it also includes a circulating fan 6, which is located in the middle of the inner side of the cover 20 and can be driven by an external motor.

[0093] The middle part of the rotating drum 41 and the material frame 42 is hollowed out along the axial direction. The hollowed-out part corresponds to the air outlet of the circulating fan 6. When the circulating fan 6 is running, its air outlet can blow downward into the hollowed-out part of the rotating drum 41 and the material frame 42 and into the lower part of the centrifugal chamber.

[0094] Meanwhile, a circulating air inlet 51 is provided on the upper side wall of the liquid-blocking cylinder 5. The circulating air inlet 51 is arranged circumferentially and connects the inside and outside of the liquid-blocking cylinder 5.

[0095] When the centrifuge is heated, the circulating fan 6 is turned on, which can draw the hot air (especially the heat generated by the heating component 211) between the side wall of the shell 2 and the outside of the baffle cylinder 5 through the circulating air port 51, into the circulating fan 6, and then into the lower part of the centrifuge chamber through the hollow part in the middle of the drum 41 and the material frame 42. Then, under the diversion and guidance of the bottom of the suspended baffle cylinder 5, it is divided into two streams, which flow upward through the gap between the inner side of the baffle cylinder 5 and the outer side of the drum 41 and the gap between the outer side of the baffle cylinder 5 and the side wall of the shell 2, respectively, and return to the upper part of the centrifuge chamber, thus forming a hot air circulation.

[0096] The combination of a circulating fan 6, a rotating drum 41, a material frame 42 with a hollowed-out middle section, a liquid baffle 5 with a suspended lower section and a circulating air vent 51 at the top, etc., can draw the heat generated by the heating component 211 on the inner wall of the shell 2 into other parts of the centrifugal chamber, and form a heat circulation loop from the outside to the inside and from the bottom to the top in the centrifugal chamber. This allows the heat generated by the heating component 211 to be evenly distributed in the centrifugal chamber, accelerating the heating of the material and making the material heating more uniform and with high thermal energy utilization.

[0097] See Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the drive assembly includes a centrifugal drive assembly and a material frame positioning drive assembly.

[0098] The centrifugal drive assembly includes a centrifugal drive motor 71 and a first transmission component. The centrifugal drive motor 71 is mounted on the base 1, and its output end is connected to the lower end of the main shaft 3 via the first transmission component. It drives the main shaft 3 and the drum 41 to rotate, thereby causing the material frame 42 and the material box 43 to rotate, achieving solid-liquid centrifugal separation of the material within the material box 43. That is, the centrifugal drive motor 71 is a high-speed motor, mainly used to drive the centrifuge.

[0099] The material frame positioning drive assembly includes an indexing plate 741, a detector 742, a positioning drive component 73, and a second transmission component. The indexing plate 741 is coaxially fixedly mounted on the lower part of the main shaft 3, rotating synchronously with the main shaft 3. The number of equal divisions and the installation position of the indexing plate correspond to the partitions 421 of the material frame 42; that is, each equal division of the indexing plate 741 corresponds to one partition 421. The detector 742 is fixedly mounted on the bottom of the housing 2, corresponding to the indexing plate 741, and can detect each equal division of the indexing plate 741. The detector 742 can be a signal detection switch; when aligned with any equal division of the indexing plate 741, it can emit a detection signal. Preferably, the detector 742 is connected to an acoustic / photoelectric indicator, a display, a controller, etc., to convert the detection signal for prompting or control.

[0100] The output end of the positioning drive 73 is connected to the main shaft 3 or the first drive via the second transmission component. When the centrifugal force stops, it is used to drive the material frame 42 to rotate to the required position at a low speed so that the separator frame 421 corresponds to the loading and unloading port 201 in sequence, which facilitates the unloading and loading of the material frame 43 from the loading and unloading port 201.

[0101] Furthermore, the first transmission component includes a first pulley 721, a second pulley 722, and a first belt 723. The first pulley 721 is coaxially fixedly installed on the lower part of the main shaft 3, the second pulley 722 is installed on the output end of the centrifugal drive motor 71, and the first belt 723 connects the first pulley 721 and the second pulley 722 to realize transmission.

[0102] like Figure 1 and Figure 7 As shown, the positioning drive 73 is preferably a manual drive, which rotates the drum 41 at low speed by manual control to rotate the material frame 42 to the corresponding position.

[0103] The positioning drive component 73 includes a hand crank 731, a first bevel gear 732, a second bevel gear 733, a worm gear 734, a worm wheel 735, and a lifting connecting rod 736. The hand crank 731 is rotatably mounted on the housing of the positioning drive component 73. One end (outer end) serves as a handle, while the other end (inner end) is coaxially fixed with a first bevel gear 732. The first bevel gear 732 meshes with a second bevel gear 733, which is coaxially fixed to one end of a worm gear 734. The worm gear 734 is perpendicular to the hand crank 731. The worm gear 734 meshes with a worm wheel 735, which is sleeved onto a vertically positioned lifting connecting rod 736 via a sleeve portion. The worm wheel 735 is circumferentially limited by a guide key and rotatably mounted inside the housing via the sleeve portion. Rotation of the worm wheel 735 drives the lifting connecting rod 736 to rotate, and the lifting connecting rod 736 can move axially up and down relative to the worm wheel 735. In other words, rotation of the hand crank 731 drives the lifting connecting rod 736 to rotate.

[0104] The second transmission component includes a third pulley 752, a fourth pulley 751, and a second belt 753. The third pulley 752 engages with the lower end of the lifting connecting rod 736. The axial movement of the lifting connecting rod 736 allows it to engage with the third pulley 752 for circumferential locking, or to disengage. Preferably, as shown... Figure 7 As shown, the lifting connecting rod 736 is a lead screw with a handwheel on the upper part. Rotating the handwheel can drive the lifting connecting rod 736 to rise or fall. When the lifting connecting rod 736 descends, it can be coaxially engaged with the upper part of the third pulley 752. At this time, the rotation of the lifting connecting rod 736 can drive the third pulley 752 to rotate. When the lifting connecting rod 736 rises, the engagement with the third pulley 752 can be released.

[0105] The fourth pulley 751 is either driven or coaxially fixedly connected to the second pulley 722. Rotation of the fourth pulley 751 can drive the second pulley 722 to rotate. The second belt 753 connects the third pulley 752 and the fourth pulley 751. Therefore, when centrifugation stops, the lifting connecting rod 736 is engaged with the third pulley 752. Rotation of the hand crank 731 drives the lifting connecting rod 736 to rotate. Then, through the second transmission component and the first transmission component, the main shaft 3, the drum 41, and the material frame 42 can be driven to rotate at low speed. Combined with the detection of the indexing plate 741 by the detector 742, the material frame 42 can be rotated to the position corresponding to the partition frame 421 and the loading and unloading port 201, thereby achieving accurate loading and unloading of the material frame 43.

[0106] In one implementation, such as Figure 1and Figure 8 As shown, the bearing assembly includes a bearing housing 31, a bearing 32, an upper bearing housing cover 33, and a lower bearing housing cover 34. The bearing housing 31 is partially embedded in the heat-insulating base 22 of the housing 2, providing an installation position for the spindle 3. The spindle 3 is rotatably mounted in the bearing housing 31 via the bearing 32. The upper bearing housing cover 33 is installed at the upper end of the bearing housing 31, and the lower bearing housing cover 34 is installed at the lower end of the bearing housing 31, thereby enabling the spindle 3 to be rotated and axially limited within the bearing housing 31.

[0107] Preferably, the bearing housing 31 has a cylindrical first cooling chamber 311, which is equipped with spiral guide vanes. The upper and lower ends of the first cooling chamber 311 are respectively provided with cooling medium inlets or outlets, so that the cooling medium can be evenly distributed and flow through the first cooling chamber 311. The upper bearing housing cover 33 has a second cooling chamber 331. The main shaft 3 is a hollow shaft, and a third cooling chamber 301 is provided axially inside. The lower end of the main shaft 3 is open, and the upper end is blind. The lower end of the main shaft 3 is connected to the coolant inlet / outlet connector 35. The inlet pipe of the coolant inlet / outlet connector 35 extends into the top of the third cooling chamber 301, and the coolant is sent into the top of the third cooling chamber 301 and then discharged from the lower end opening and the outlet channel of the coolant inlet / outlet connector 35.

[0108] Preferably, a cooling medium circulation device is also provided, which is connected to the first cooling chamber 311, the second cooling chamber 331, and the third cooling chamber 301 respectively, to provide a stable cooling medium for the first cooling chamber 311, the second cooling chamber 331, and the third cooling chamber 301. The first cooling chamber 311, the second cooling chamber 331, and the third cooling chamber 301 are set in the bearing assembly to cool different parts of the main shaft 3, so that the main shaft 3 and the bearing assembly can be maintained at a stable operating temperature. This effectively avoids unstable centrifugal operation and accelerated wear of the main shaft 3 and the bearing assembly due to overheating, ensuring stable operation of the centrifuge and extending the service life of the centrifuge.

[0109] like Figure 2 and Figure 3 As shown, preferably, the high-temperature centrifuge also includes a hoisting mechanism 8, which can be a robotic arm, suspension arm, etc., movable to match the position of the loading / unloading port 201 when the cover 20 is closed. The material frame 43 can be loaded or unloaded through the loading / unloading port 201, realizing mechanical loading and unloading. The hoisting mechanism 8 reduces manual operation, especially enabling loading and unloading without cooling, shortening loading and unloading time and improving centrifugation efficiency.
