Wherein the dispersing barrel 101 has a barrel inner space 1010 for containing the slurry to be dispersion-treated. The dispersing wheel 102 is rotatably arranged in the barrel inner space 1010, and the dispersing wheel 102 is driven by the driving motor 103 to rotate around a central axis S at a high speed, so that the slurry in the dispersing barrel 101 is dispersed; the central axis S here corresponds to the axis of the dispersing wheel 102 or the barrel space 1010. The driving spindle 104 is used for transmission between the driving motor 103 and the dispersing wheel 102, and specifically, one end of the driving spindle 104 is connected to the dispersing wheel 102 in a rotation-stopping manner, and the other end is connected to an output shaft of the driving motor 103 through a coupling. The bearing housing 105 is used to mount a plurality of bearings 106 through which the drive shaft 104 passes, and the bearing housing 105 is formed with a housing space 1050 that accommodates the bearings 106.

The high-speed rotation of the dispersing wheel 102 generates a large amount of heat, and the slurry collides during dispersion to generate heat, which needs to be dissipated in time, so that once the heat is accumulated, the heat has great influence on the quality of the slurry and great damage to equipment.

Referring to fig. 4 to 8, the high-speed disperser 100 preferably further includes a first cooling system 20 for cooling the dispersing barrel 101, and the first cooling system 20 includes a first interlayer space formed or disposed on the dispersing barrel 101. Wherein the first interlayer space is distributed around the barrel space 1010, the first interlayer space being configured to have: a first liquid inlet 21, a first liquid outlet 22 and a first cooling channel 23. Wherein, the first liquid inlet 21 is formed or arranged outside the dispersion barrel 101 and is used for allowing the cooling liquid to flow into the first interlayer space; a first liquid outlet 22 is formed or arranged outside the dispersion barrel 101 and used for allowing the cooling liquid to flow out of the first interlayer space; the first cooling flow passage 23 extends from the first liquid inlet 21 to the first liquid outlet 22 so that the flow of the cooling liquid in the first cooling flow passage 23 has at least motion components in a first direction, a second direction and a third direction perpendicular to each other. Specifically, the first direction may be defined as a direction parallel to the central axis S, and the second direction and the third direction are configured as two mutually perpendicular directions on a plane perpendicular to the central axis S.

As shown in fig. 4 to 8, as a concrete scheme, the first cooling flow passage 23 includes a circulation flow passage 231 and a communication flow passage 232. The plurality of circulation flow paths 231 are provided, and the plurality of circulation flow paths 231 are formed at different axial positions (the axial positions are in a direction parallel to the central axis S) of the first interlayer space and extend so as to surround the barrel space 1010. Specifically, the plurality of circulation flow channels 231 are partitioned by a plurality of first partition plates 24 axially spaced apart in the sandwiched space. The number of the communication flow passages 232 is plural, and the plural communication flow passages 232 are formed between two adjacent circulation flow passages 231 in the axial direction to communicate the two circulation flow passages 231. Specifically, the communication flow passage 232 is formed in the first partition plate 24 in the axial direction. By providing the circulation flow channel 231 and the communication flow channel 232 so that the cooling liquid flows in the cooling flow channel in a spatially folded manner, heat generated when the slurry in the dispersing barrel 101 is dispersed is absorbed.

Referring to fig. 5 and 6, as a preferable mode, the two communication flow passages 232 are provided at different circumferential positions (the circumferential positions are in a direction around the central axis S).

As a further alternative, as shown in fig. 5 and 6, two opposing circumferential positions are provided in two communication flow passages 232 adjacent in the axial direction, so that the circulation flow passage 231 has the longest stroke in the circumferential direction through which the cooling liquid can flow, whereby the cooling liquid absorbs the heat in the dispersion barrel 101 to the greatest extent. Wherein "relative position" is specifically interpreted as: with a plane perpendicular to the central axis S as a reference plane, an included angle between the center of the projection of the two axially adjacent communicating flow channels 232 on the reference plane and a connecting line of the projection points of the central axis S on the reference plane is 180 °.

As shown in fig. 7 and 8, the communication flow passage 232 may preferably be formed in one of a circular hole shape and a kidney-shaped hole shape according to a design flow rate of the coolant.

As shown in fig. 5 and 6, the first inlet port 21 and the first outlet port 22 are preferably provided at different axial positions.

Preferably, the flow path cross section of the annular flow path 231 has at least one linear cross sectional profile, where the "flow path cross section" is a cross section formed by cutting the annular flow path 231 in a plane passing through and coinciding with the central axis S. The cross-sectional profile is parallel to the central axis S and is located on the side of the flow passage cross section close to the central axis S, so that the maximum area surrounding the barrel inner space 1010 is provided in the circumferential direction of the annular flow passage while the safe wall thickness of the dispersion barrel 101 is ensured, and the cooling area is large, so that the heat generated in the barrel inner space 1010 can be sufficiently absorbed by the cooling liquid in the annular flow passage.

As a further alternative, as shown in fig. 4, the cross-sectional profiles of the flow passage sections of the circulation flow passage 231 in the axial direction are all straight lines parallel to the central axis S, and the cross-sectional profiles of the flow passage sections of the circulation flow passage 231 in the radial positions (in any direction perpendicular to the central axis S) are all straight lines perpendicular to the central axis S, and at this time, the cross-sectional shape of the annular flow passage is rectangular, so as to ensure the flow rate of the cooling liquid in the annular flow passage.

Referring to fig. 4, 9 and 10, as a preferable scheme, a plurality of flow guiding members 25 are further disposed in the interlayer space of the dispersing barrel 101, the flow guiding members 25 are disposed at least in the circulation flow channel 231, and the flow guiding members 25 guide the passing cooling liquid to prolong the heat absorption time of the flow in the circulation flow channel 231. Specifically, one circulation flow channel (defined as a sub-flow channel 233) axially distant from the first liquid outlet 22 is located at one end of the barrel space 1010, a communication flow channel 232a close to the first liquid inlet 21 and a communication flow channel 232b distant from the first liquid inlet 21 are formed in the first partition plate 24 adjacent to the sub-flow channel 233, and the cooling liquid flowing from the first liquid outlet 22 first enters the sub-flow channel 233 through the communication flow channel 232a and then enters the next circulation flow channel 231 through the communication flow channel 232b to cool the end region of the barrel space 1010.

The flow guiding elements 25 are formed in the secondary flow channel 233, a connecting line between the center of the communicating flow channel 232a and the center of the communicating flow channel 232b is perpendicular to at least one flow guiding element 25, and the extension lines of the plurality of flow guiding elements 25 are sequentially intersected end to form a polygon. The cooling liquid is fully diffused in the auxiliary flow channel 233 by the guiding function of the flow guide 25, and the heat absorption effect is improved.

As a further alternative, as shown in fig. 11 to 13, the dispersing barrel 101 includes a feeding barrel body 1011, a discharging barrel body 1012, and a partition 1013; wherein the feeding barrel body 1011 is provided with a feeding port 1014 of the dispersing barrel 101, and the feeding barrel body 1011 forms a first interlayer space, so that the first cooling system 20 mainly cools the feeding barrel body 1011; the discharging barrel body 1012 is provided with a discharging hole 1015 of the dispersing barrel 101. The partition 1013 is provided between the feed barrel 1011 and the discharge barrel 1012 and is provided with a central hole through which at least the driving main shaft 104 passes. The dispersing wheel 102 is disposed at the inter-barrel space formed by the feeding barrel body 1011 and at a side of the partition 1013 near the feed port 1014. The inner diameter of the central hole is larger than the outer diameter of the driving main shaft 104, so that the dispersed slurry can enter the discharging barrel body 1012 from the feeding barrel body 1011 through the space between the driving main shaft 104 and the central hole.

Referring to fig. 11 to 13, the high-speed disperser 100 preferably further includes a second cooling system 30 for cooling the discharging barrel body 1012, and the second cooling system 30 includes a second interlayer space formed or disposed on the discharging barrel body 1012. Wherein the second interlayer space is distributed around the space inside the tub, the second interlayer space being configured to have: a second inlet port 31, a second outlet port 32, and a second cooling channel 33. The second liquid inlet 31 is formed on or arranged outside the material storage barrel body and is used for allowing cooling liquid to flow into the second interlayer space; the second liquid outlet 32 is formed or arranged outside the discharging barrel body 1012 and is used for allowing the cooling liquid to flow out of the second interlayer space; the second cooling flow passage 33 extends from the second inlet port 31 to the second outlet port 32 so that the flow of the cooling liquid in the second cooling flow passage 33 has at least motion components in a first direction, a second direction and a third direction perpendicular to each other. Specifically, the first direction may be a direction parallel to the central axis S, and the second direction and the third direction may be configured as two mutually perpendicular directions on a plane perpendicular to the central axis S.

As shown in fig. 11 to 13, as a concrete configuration, the second cooling flow passage 33 includes a circulation flow passage 331 and a communication flow passage 332. The number of the circulation flow paths 331 is plural, and the plural circulation flow paths 331 are formed at different axial positions (the axial positions are directions parallel to the central axis S) of the second interlayer space and extend so as to surround the space in the tub. Specifically, the plurality of circulation flow paths 331 are partitioned by a plurality of second partition plates 34 axially spaced apart in the sandwiched space. The communication flow path 332 is provided with a plurality of communication flow paths 332, and the plurality of communication flow paths 332 are formed between two adjacent circulation flow paths 331 in the axial direction to communicate the two circulation flow paths 331. Specifically, the communication flow passage 332 is formed in the second partition plate 34 in the axial direction. By providing the circulation flow path 331 and the communication flow path 332, the cooling liquid flows in the second cooling flow path in a spatially returning manner, thereby absorbing the heat of the slurry in the discharge bucket and preventing the slurry from being overheated to affect the characteristics of the slurry.

Referring to fig. 11 to 13, an axis of the discharge hole 1015 of the dispersing barrel 101 is disposed perpendicular to the central axis S, and the discharge hole 1015 passes through the second cooling flow passage 33 so that the slurry passing through the discharge hole 1015 may be further cooled. One of the second partitions 34 at least partially overlaps the outlet 1015 in the axial direction, so that the outlet 1015 is in contact with the cooling fluid in at least two adjacent circulation channels, thereby prolonging the cooling time. The second partition 34 has a notch for the discharge opening 1015 to pass through, and a partially circular communication flow passage 332 is formed at the notch.

Referring to fig. 14 to 17, the high speed disperser 100 preferably further includes a third cooling system 40 for cooling the bearing housing 105, and the third cooling system 40 includes a third sandwiched space formed or provided on the bearing housing 105. Wherein the third interlayer space is distributed around the seat space 1050, the third interlayer space being configured to have: a third liquid inlet 41, a third liquid outlet 42 and a third cooling channel 43. The third liquid inlet 41 is formed on or arranged outside the bearing seat 105 and is used for allowing cooling liquid to flow into the third interlayer space; a third liquid outlet 42 is formed on or arranged outside the bearing seat 105, and is used for allowing the cooling liquid to flow out of the third interlayer space; the third cooling flow channel 43 extends from the third liquid inlet 41 to the third liquid outlet 42 so that the flow of the cooling liquid in the third cooling flow channel 43 has at least motion components in a first direction, a second direction and a third direction perpendicular to each other. Specifically, the first direction may be a direction parallel to the central axis S, and the second direction and the third direction are configured as two mutually perpendicular directions on a plane perpendicular to the central axis S.

As shown in fig. 14 to 17, as a concrete configuration, the third cooling flow passage 43 includes a circulation flow passage 431 and a communication flow passage 432. The circulation flow passages 431 are provided in plural, and the plural circulation flow passages 431 are formed at different axial positions (the axial positions are directions parallel to the central axis S, which is equivalent to the axis of the drive spindle 104 or the seat space 1050) of the third sandwiched space and extend so as to surround the seat space 1050. Specifically, the plurality of circulation flow passages 431 are partitioned by a plurality of third partition plates 44 axially spaced apart in the sandwiched space. The plurality of communication flow passages 432 are provided, and the plurality of communication flow passages 432 are formed between two adjacent circulation flow passages 431 in the axial direction to communicate the two circulation flow passages 431. Specifically, the communication flow passage 432 is formed in the axial direction on the third partition plate 44. By providing the circulation flow passage 431 and the communication flow passage 432, the cooling liquid flows in the third cooling flow passage in a spatially returning manner, and heat generated in the seat space 1050 is absorbed, thereby achieving rapid heat dissipation of the bearing 106.

As shown in fig. 16 and 17, the communication flow path 432 may be preferably formed in one of a circular hole shape and a kidney-shaped hole shape according to a designed flow rate of the coolant.

Referring to fig. 18, as an alternative, a longitudinal partition plate 45 is formed in the third sandwiched space in a direction parallel to the central axis S, and the communication flow passages 432a of the axially adjacent third partition plates 44 are located on both sides of the longitudinal partition plate 45, so that the path taken by the cooling liquid on one circulation passage is almost a full circle, and the heat of the seat space 1050 can be diffused into the cooling liquid for a long time.

In the scheme, the cooling flow channel is formed into the circulation flow channel and the communication flow channel, so that the flowing time of the cooling liquid in the cooling flow channel is prolonged to improve the heat dissipation effect, however, compared with the traditional cooling mode, the radial multilayer circulation flow channel has the advantage that the residence time of the cooling liquid absorbed in the cooling flow channel under the same cooling liquid flow speed is not particularly obvious.

As a further alternative, as shown in fig. 19 and 20, a plurality of layers of circulation passages 433a are provided in the radial direction of the central axis S, the circulation passages of two radially adjacent layers are connected by the transfer passages 434, and the two radially adjacent transfer passages 434 are provided at different axial positions. For example, in one embodiment of the present application, the interlayer space is formed with an inner flow path 4331, a middle flow path 4332 and an outer flow path 4333. By arranging the multilayer circulation channels, the flowing time of the cooling liquid in the cooling flow channel is further prolonged, and the heat dissipation effect is improved.

An inter-wall space 46 which is through in the axial direction and the circumferential direction is arranged between the two adjacent layers of circulation channels, and the inter-wall space 46 is filled with phase change materials. By utilizing the characteristics of the phase-change material, when the temperature of the circulation channel reaches the phase-change temperature, the phase-change material absorbs heat without increasing the temperature, and the temperature of the heat-generating part of the dispersion machine is ensured not to be increased too much in a short time. Meanwhile, when the high-speed dispersion machine stops, heat absorbed by the phase-change material is diffused to cooling liquid in the circulation channel, and quick heat dissipation to room temperature is achieved.

In order to adapt to the temperature of the cooling liquid in each layer of the circulation flow passage 431 in the radial direction, the phase transition temperature of the phase change material in the inner-layer wall space 46 is higher than that of the phase change material in the outer-layer wall space 46.

Referring to fig. 21 to 24, when a heat generating portion of the high speed disperser is overheated, and the coolant may reach the highest temperature through the inner layer flow channel 4331, the outer layer flow channel cannot achieve the effect of auxiliary heat dissipation, and the coolant needs to be rapidly discharged. As a further proposal, a temporary water outlet point 436 is further provided between the inner layer flow channel 4331 and the liquid outlet 42a, the temporary water outlet point 436 is provided with a flexible bag 51 near one side of the inner layer flow channel 4331, the inner space of the flexible bag 51 is communicated with an in-wall space 46 near the central axis S, the phase change material in the in-wall space is partially filled into the flexible bag 51, and the temporary water outlet point 436 is blocked when the flexible bag 51 is filled with the phase change material. An arc-shaped limiting part 437 is formed on the inner wall of the middle flow channel 4332 close to the central flexible bag 51, so as to limit the shape of the flexible bag 51 filled with the phase change material. The phase change temperature of the inner layer phase change material is designed to be the safe temperature of the heat generating part of the dispersion machine (when the temperature is higher than the safe temperature, the temperature is regarded as overheating), when the temperature of the inner layer circulation flow channel 431 reaches the safe temperature, the phase change material of the inner layer is changed from a solid phase to a liquid phase, the flexible bag 51 is extruded into the inner wall space under the action of the cooling hydraulic pressure in the inner layer flow channel 4331, so that the temporary water outlet point 436 is opened, and the overheated cooling liquid in the inner layer flow channel 4331 directly flows out through the temporary water outlet point 436 and the liquid outlet 42 a.

Referring to fig. 25, as an alternative, a plurality of circulation passages 433b are provided in the radial direction of the central axis S, an inter-wall space 46 that penetrates in the circumferential direction is provided between the circulation passages 433b of adjacent two layers, and the inter-wall space 46 is filled with a phase change material. The phase transition temperature of the phase change material in the in-wall space 46 gradually decreases from the inlet 41 toward the outlet 42.

It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above.
