Description

An integrated mixing and grinding machine Technical Field

[0001] The present invention relates to the technical field of grinding equipment, in particular to an integrated stirring grinder. Background Art

[0002] Fine grinding of macromolecular particles in slurry is one of the key research directions in the field of grinding. Existing pin-type grinding machines generally fix the pin on the main shaft. When the main shaft rotates, the pin drives the grinding balls (also known as zirconia balls, zirconium balls) to collide with each other, thereby grinding the macromolecular particles in the slurry. However, the defect of the pin-type grinding machine is that the movement trajectory of the grinding balls inside the traditional pin-type grinding machine is irregular. The grinding of the slurry can only rely on the random grinding of the grinding balls. The slurry is not processed in stages of coarse grinding and fine grinding, which results in some slurry not being fully ground. filtration, and the grinding fineness is not high enough; on the other hand, when the main shaft rotates, each rod pin needs to stir between the grinding balls, resulting in a large resistance between multiple groups of rod pins and the grinding balls, and the rotation speed of the main shaft cannot be increased. Although the grinding force between the grinding balls is large, the movement of the grinding balls is not active enough, resulting in insufficient grinding of the slurry. In this context, the applicant is committed to developing an integrated stirring grinder to achieve staged processing of coarse grinding and fine grinding of the slurry, further improve the fineness of the grinding, and further improve the movement activity of the grinding balls, so that the slurry is more fully ground.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] As shown in Figures 1 to 6, an integrated stirring grinder includes a driving mechanism 1, a grinding cylinder 2, a main shaft 3, a turbine 4, a rotating seat 5, a plurality of rod pins 6, a filter cylinder 7, a feed pipe 8, a discharge pipe 9, a plurality of grinding balls, a fixed seat 10, a vibrator 11, a bead feed pipe 12, a cooling mechanism,

[0025] The feed pipe 8 and the discharge pipe 9 are respectively arranged at the two ends of the grinding cylinder 2. The more specific structure is: the feed pipe 8 is fixedly set at one end of the grinding cylinder 2, and the discharge pipe 9 is located at the other end of the grinding cylinder 2. The fixing seat 10 is fixedly set on the end of the grinding cylinder 2 close to the discharge pipe 9, and the vibrator 11 is fixedly set on the fixing seat 10. The end of the filter cylinder 7 close to the discharge pipe 9 is also fixedly set on the fixing seat 10, and the vibrating end of the vibrator 11 extends into the filter cylinder 7. When the vibrator 11 vibrates at high frequency, the high-frequency vibration is transmitted to the filter cylinder 7 through the fixing seat 10, thereby shaking off the large particles in the slurry from the filter cylinder 7, avoiding clogging of the filter cylinder 7 to a certain extent.

[0026] The driving mechanism 1 drives the main shaft 3 to rotate. One end of the main shaft 3 extends into the grinding cylinder 2 from the end of the grinding cylinder 2 close to the feed pipe 8, and is fixedly connected to the rotating seat 5. The filter cylinder 7 is fixedly arranged inside the grinding cylinder 2 at one end close to the discharge pipe 9. The discharge pipe 9 is connected to the inside of the filter cylinder 7, and the end of the filter cylinder 7 away from the discharge pipe 9 extends into the rotating seat 5.

[0027] When the slurry enters the interior of the grinding cylinder 2 from the feed pipe 8 until it reaches the discharge pipe 9, it needs to flow from one end of the grinding cylinder 2 to the other end. While flowing, the grinding time of the slurry is also greatly prolonged, thereby extending the time for the slurry to be ground, making the grinding more sufficient and thorough, greatly reducing large particles, and to a certain extent reducing the frequency of cleaning or replacement of the filter cylinder 7, thereby improving the grinding efficiency.

[0028] The turbine 4 is fixedly arranged on the main shaft 3, and a through groove 41 is formed through the end face of the turbine 4. A centrifugal groove 42 is formed on the wheel surface of the turbine 4, and the through groove 41 is connected to the centrifugal groove 42. A plurality of rod pins 6 are evenly distributed on the circumferential surface of the rotating seat 5, and a flow groove 51 is formed on the circumferential surface of the rotating seat 5. The grinding balls are placed inside the grinding cylinder 2, and the central axes of the grinding cylinder 2, the main shaft 3, the turbine 4, the rotating seat 5, and the filter cylinder 7 are all collinear.

[0029] The present invention fixes the turbine 4 on the main shaft 3. When the turbine 4 rotates, the resistance of the wheel surface of the turbine 4 in its rotation direction from the grinding balls will be greatly reduced. At the same time, the present invention arranges the rod pins 6 on the rotating seat 5. Compared with the traditional technology, the number and length of the rod pins 6 used in the present invention are greatly reduced, thereby greatly reducing the resistance between the rod pins 6 and the grinding balls, so that the main shaft 3 can rotate at a high speed. In addition, the present invention has a through groove 41 running through the end face of the turbine 4, and a centrifugal groove 42 is opened on the wheel surface of the turbine 4. The through groove 41 is connected to the centrifugal groove 42, and the side of the turbine 4 is connected to the centrifugal groove 42. The grinding balls on the surface can squeeze into each other's grooves 41, and the rotation of the turbine 4 generates centrifugal force, which throws the grinding balls in the grooves 41 out of the centrifugal grooves 42, thereby making the movement of the grinding balls more active and the mutual collision and extrusion between the grinding balls more frequent; on the other hand, the present invention provides flow grooves 51 on the circumferential surface of the rotating seat 5, and the flow grooves 51 are conducive to the flow of the grinding balls from the inside of the rotating seat 5 to the grinding cylinder 2, and cooperates with the stirring effect of the rod pin 6 to make the movement of the grinding balls more active, thereby more fully grinding the large particles in the slurry, and making the slurry more fully ground.

[0030] The bead inlet tube 12 is fixedly arranged on the grinding cylinder 2 and is communicated with the inner space of the grinding cylinder 2 . Grinding balls can be added into the grinding cylinder 2 through the bead inlet tube 12 .

[0031] The cooling mechanism includes a liquid inlet pipe 131, a liquid outlet pipe 132, an external cooling cylinder 133, a coolant, a feed cooling tank 134, a heat exchange tank 135, a heat exchange pipe 136, a circulation pipe 137, a circulating liquid and a pump. The external cooling cylinder 133 is fixedly arranged on the outer surface of the grinding cylinder 2, and an accommodating space is formed between the external cooling cylinder 133 and the grinding cylinder 2. The liquid inlet pipe 131 and the liquid outlet pipe 132 are both connected to the inside of the accommodating space, and the coolant circulates in the liquid inlet pipe 131, the liquid outlet pipe 132 and the accommodating space.

[0032] When the grinding balls collide with each other, a large amount of heat is generated. At this time, the grinding cylinder 2 needs to be cooled. The coolant in the liquid inlet pipe 131 flows into the accommodating space under the drive of external equipment, and finally flows out from the liquid outlet pipe 132 to other heat dissipation equipment, thereby taking away the heat of the grinding cylinder 2 and achieving cooling.

[0033] The liquid inlet pipe 131 and the liquid outlet pipe 132 are respectively connected to the upper and lower parts of the feed cooling tank 134. The feed pipe 8 runs through the feed cooling tank 134. When the coolant in the liquid inlet pipe 131 and the liquid outlet pipe 132 flows through the feed cooling tank 134, it contacts the feed pipe 8 and exchanges heat, bringing the heat of the feed pipe 8 into the feed pipe 8, thereby cooling the feed in the feed pipe 8.

[0034] Both ends of the circulation pipe 137 are connected to the interior of the heat exchange tank 135. The pump pumps the circulating liquid to circulate in the circulation pipe 137. The circulation pipe 137 cooperates with the driving mechanism 1. The heat exchange pipe 136 is located in the heat exchange tank 135, and the two ends of the heat exchange pipe 136 are respectively connected to the liquid inlet pipe 131 and the liquid outlet pipe 132.

[0035] The circulation pipe 137 is wound around the driving mechanism 1 and is used to conduct the heat generated by the driving mechanism 1 when it is working. When the pump pumps the circulating fluid to circulate in the circulation pipe 137, the heat generated by the driving mechanism 1 when it is working is taken away. When the circulating fluid flows through the heat exchange tank 135, the heat is conducted to the heat exchange pipe 136. When the coolant in the liquid inlet pipe 131 flows through the heat exchange pipe 136, the heat is taken away from the heat exchange pipe 136. The coolant finally flows out from the liquid outlet pipe 132 and takes the heat to other heat dissipation mechanisms for dissipation.

[0036] The grinding cylinder 2 and the driving mechanism 1 are both fixedly arranged on the frame.

[0037] The working principle of the present invention is as follows: the driving mechanism 1 drives the main shaft 3 to rotate, the main shaft 3 drives the turbine 4 and the rotating seat 5 to rotate at high speed, the grinding balls on the side of the turbine 4 squeeze each other and squeeze into the through groove 41, the rotation of the turbine 4 generates centrifugal force, and the grinding balls in the through groove 41 are thrown out from the centrifugal groove 42. At the same time, the grinding balls in the rotating seat 5 flow between the rotating seat 5 and the grinding cylinder 2 through the flow groove 51, and cooperate with the stirring effect of the rod pin 6, so that the movement of the grinding balls is more active, and the mutual collision and extrusion between the grinding balls are also more frequent, so that the large particles in the slurry are more fully ground, and the grinding accuracy is improved.

[0038] When the slurry enters the interior of the grinding cylinder 2 from the feed pipe 8 until it reaches the discharge pipe 9, it needs to flow from one end of the grinding cylinder 2 to the other end. While flowing, the grinding time of the slurry is greatly extended, further improving the fineness of the grinding.

[0039] When the grinding balls collide with each other, a large amount of heat is generated. The coolant in the liquid inlet pipe 131 flows into the accommodating space under the drive of external equipment, and finally flows out from the liquid outlet pipe 132 to other heat dissipation equipment, thereby taking away the heat of the grinding cylinder 2 and cooling the grinding cylinder 2.

[0040] When the coolant in the liquid inlet pipe 131 and the liquid outlet pipe 132 flows through the feed cooling tank 134, it contacts the feed pipe 8 and exchanges heat, bringing the heat of the feed pipe 8 into the feed pipe 8 to cool the feed in the feed pipe 8.

[0041] When the pump pumps the circulating fluid to circulate in the circulating pipe 137, the heat generated by the driving mechanism 1 during operation is taken away. When the circulating fluid flows through the heat exchange tank 135, the heat is transferred to the heat exchange pipe 136. When the coolant in the liquid inlet pipe 131 flows through the heat exchange pipe 136, the heat of the heat exchange pipe 136 is taken away. Finally, the coolant flows out from the liquid outlet pipe 132 and takes the heat to other heat dissipation mechanisms for dissipation, thereby achieving cooling of the driving mechanism 1.

[0042] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention. The above does not impose any limitation on the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
