[0001] The invention relates to the technical field of stirring devices, in particular to a stirring device for impregnated pulp processing. Background Art

[0002] A pulp stirring device is usually a device used in the pulp production process. Its main function is to mix raw materials such as cellulose with water and keep them in a suspended state to facilitate the subsequent paper making process.

[0003] For example, Chinese patent CN108889184B discloses an anti-sedimentation efficient pulp stirring device, which efficiently stirs the pulp through a stirring mechanism, and pushes the settled pulp up from the bottom of the stirring tank through the pulp pushing arc plate in the anti-sedimentation mechanism, so that the settled pulp is fully stirred.

[0004] However, during the use of the above-mentioned anti-sedimentation high-efficiency pulp stirring device, the settled pulp is pushed up and randomly dispersed outward, resulting in uneven distribution of pulp concentration in the stirring device, affecting the stirring effect. At the same time, as the stirring time increases, the flow rate of the pulp driven by the stirring mechanism gradually tends to the rotation speed of the stirring mechanism, resulting in poor stirring effect of the stirring mechanism on the pulp.

[0011] A driving mechanism is located on the shell, and is used to drive the first stirring shaft and the second stirring shaft to rotate.

[0012] Furthermore, the driving mechanism includes a first driving motor and a second driving motor, the first driving motor is located at the bottom of the shell, the rotating shaft of the first driving motor is fixedly connected to the first stirring shaft, the second driving motor is located above the shell, and the second driving motor drives multiple second stirring shafts to revolve around the first stirring shaft.

[0013] Furthermore, a rotating ring is provided in the shell, and the lower end surface of the rotating ring is fixedly connected to multiple second stirring shafts. The inner circumference of the rotating ring has teeth, and the rotating shaft of the second drive motor is engaged with the teeth. The rotation of the rotating ring drives the multiple second stirring shafts to revolve around the first stirring shaft.

[0014] Furthermore, the rotation speeds of the first drive motor and the second drive motor are adjustable. When the rotation speed of the first stirring shaft is greater than the revolution speed of the second stirring shaft, the area of ​​the pulp pushed upward by the first stirring shaft increases; when the rotation speed of the first stirring shaft is less than the revolution speed of the second stirring shaft, the area of ​​the pulp pushed upward by the second stirring shaft increases.

[0015] Furthermore, several first stirring blades on the first stirring shaft can move radially along the first stirring shaft, and the distance between the several first stirring blades and the first stirring shaft gradually increases from bottom to top; several second stirring blades on the second stirring shaft can move radially along the second stirring shaft, and the distance between the several second stirring blades and the second stirring shaft gradually increases from bottom to top, and the pulp moves in a direction away from the first stirring shaft or the second stirring shaft.

[0016] Furthermore, the first stirring shaft is hollow inside, and a first conical rod is provided in the first stirring shaft, the tip of the first conical rod faces downward, and the first conical rod moves downward along the axial direction of the first stirring shaft to push a plurality of first stirring blades to move along the radial direction of the first stirring shaft away from the first stirring shaft; a plurality of second stirring shafts are hollow inside, and a second conical rod is provided in each of the second stirring shafts, the tip of the second conical rod faces downward, and the second conical rod moves downward along the axial direction of the second stirring shaft to push a plurality of second stirring blades to move along the radial direction of the second stirring shaft away from the second stirring shaft.

[0017] Furthermore, a first telescopic member is provided on the shell, and the first telescopic member controls the axial movement of the first conical rod along the first stirring shaft.

[0018] Furthermore, a second telescopic member is provided on the shell, and the second telescopic member controls the axial movement of the second tapered rod along the second stirring shaft.

[0022] The present invention provides a first stirring shaft and a second stirring shaft, and the first stirring shaft and the second stirring shaft are provided with a first stirring blade and a second stirring blade with opposite inclination directions, so that the stirring and mixing effect of the pulp is better. When the first stirring shaft and the second stirring shaft rotate, the pulp at the bottom is pushed upward at the same time to avoid the pulp from being deposited at the bottom of the shell. The rotation directions of the first stirring shaft and the second stirring shaft are opposite, thereby avoiding the situation where the stirring and mixing effect is poor due to the speed of the pulp flow being close to the rotation speed of the first stirring shaft and the second stirring shaft.

[0023] The present invention arranges a first driving motor and a second driving motor with adjustable speeds so that the speeds of the first stirring shaft's rotation and the second stirring shaft's revolution are different, thereby causing the critical point of the pulp to reciprocate in the radial direction within the shell, further improving the stirring and mixing of the pulp by the first stirring shaft and the second stirring shaft, and making the mixing of the pulp more uniform.

[0044] Refer to the following Figure 1-Figure 11 To describe an impregnated pulp processing stirring device provided by the present application.

[0045] A soaked paper pulp processing stirring device is suitable for stirring soaked paper pulp, comprising a shell 100, a bracket 110 is arranged below the shell 100, a feed port 120 and a discharge port 130 are opened on the shell 100, the feed port 120 is located above the shell 100, pulp raw material and water enter the shell 100 through the feed port 120, and the discharge port 130 is located below the shell 100. When the pulp is stirred and mixed evenly, it is discharged from the shell 100 through the discharge port 130. A first stirring shaft 200 is arranged in the shell 100. The first stirring shaft 200 is located at the center of the shell 100, that is, the first stirring shaft 200 is located at the axis of the shell 100. A plurality of first stirring blades 210 are arranged on the first stirring shaft 200. The plurality of first stirring blades 210 are evenly distributed along the axial direction and circumferential direction of the first stirring shaft 200. The plurality of first stirring blades 210 are inclined and have the same inclination angle and direction. When the first stirring shaft 200 rotates around its own axis, the first stirring blades 210 push the pulp in the shell 100 upward. Thereby, pulp is prevented from being deposited at the bottom of the shell 100; a plurality of second stirring shafts 300 are also arranged in the shell 100, and the plurality of second stirring shafts 300 are distributed in a circle and on the outside of the first stirring shaft 200, and a plurality of second stirring blades 310 are arranged on each second stirring shaft 300, and the plurality of second stirring blades 310 are axially distributed on the second stirring shaft 300, and the second stirring blades 310 are all inclined, and the inclination angle and direction are the same, but the inclination direction of the second stirring blades 310 is opposite to the inclination direction of the first stirring blades 210. The multiple second stirring shafts 300 do not rotate around their own axes but revolve around the axis of the first stirring shaft 200, and the direction of revolution is opposite to the direction of rotation of the first stirring shaft 200. The second stirring shaft 300 can also push the pulp upward. Since the inclination directions of the first stirring blade 210 and the second stirring blade 310 are opposite, the stirring and mixing effect of the pulp is enhanced when the pulp is stirred. Since the directions of rotation of the first stirring shaft 200 and the revolution of the second stirring shaft 300 are opposite, the flow speed of the pulp driven by the first stirring shaft 200 and the second stirring shaft 300 is avoided to be the same as the rotation speed of the first stirring shaft 200 and the second stirring shaft 300, so that the flow speed of the pulp is greatly different from the rotation speed of the first stirring shaft 200 and the second stirring shaft 300, thereby enhancing the stirring and mixing effect of the pulp and making the mixing of the pulp more uniform.

[0046] like Figure 3 , Figure 4 and Figure 5As shown, viewed from top to bottom, the first stirring shaft 200 in this embodiment rotates counterclockwise. In the direction of the counterclockwise rotation of the first stirring shaft 200, the bottom of the first stirring blade 210 is located in front of the first stirring blade 210. The inclination direction of the first stirring blade 210 enables the first stirring blade 210 to push the pulp at the bottom of the shell 100 toward the upper part of the shell 100 when the first stirring shaft 200 rotates counterclockwise. The inclination direction of the second stirring blade 310 is opposite to that of the first stirring blade 210. The plurality of second stirring shafts 300 are arranged around the first stirring shaft 200. 00 rotates clockwise, thereby also pushing the pulp at the bottom of the shell 100 to the top of the shell 100. The main stirring position of the first stirring shaft 200 is close to the center of the shell 100, and the main stirring position of the second stirring shaft 300 is close to the edge of the shell 100, so that the pulp at the bottom can be pushed to the top of the shell 100 more thoroughly, and the pulp deposition at the bottom is better avoided. At the same time, when the first stirring shaft 200 and the second stirring shaft 300 start to rotate, the first stirring blade 210 and the second stirring blade 310 can break up the pulp, further enhancing the stirring effect of the pulp.

[0047] By setting the first stirring shaft 200 and the second stirring shaft 300, and providing the first stirring blade 210 and the second stirring blade 310 with opposite inclination directions on the first stirring shaft 200 and the second stirring shaft 300, the stirring and mixing effect of the pulp is better. When the first stirring shaft 200 and the second stirring shaft 300 rotate, the pulp at the bottom is pushed upward at the same time to avoid the pulp from being deposited at the bottom of the shell 100. The rotation directions of the first stirring shaft 200 and the second stirring shaft 300 are opposite, thereby avoiding the situation where the stirring and mixing effect is poor due to the flow speed of the pulp being close to the rotation speed of the first stirring shaft 200 and the second stirring shaft 300.

[0048] In a further embodiment, a driving mechanism is disposed on the housing 100 , and the driving mechanism is used to drive the first stirring shaft 200 to rotate and the plurality of second stirring shafts 300 to revolve.

[0049] Specifically, the driving mechanism includes a first driving motor 220 and a second driving motor 320. The first driving motor 220 is fixedly arranged at the bottom of the shell 100. The rotating shaft of the first driving motor 220 is fixedly connected to the first stirring shaft 200. The first driving motor 220 drives the first stirring shaft 200 to rotate. The second driving motor 320 is located above the shell 100. The second driving motor 320 drives multiple second stirring shafts 300 to revolve around the first stirring shaft 200.

[0050] Specifically, a rotating ring 301 is provided in the shell 100, and the rotating ring 301 is connected to multiple second stirring shafts 300. Teeth 304 are provided on the inner circumferential surface of the rotating ring 301. The rotating ring 301 is rotatably set in the shell 100. An annular limit strip 302 is provided on the outer circumference of the rotating ring 301. An annular groove 303 is opened on the inner circumferential wall of the shell 100. The annular limit strip 302 is located in the annular groove 303, so that the rotating ring 301 is rotatably set in the shell 100. A gear 321 is fixedly provided on the rotating shaft of the second drive motor 320, and the gear 321 is meshed with the teeth 304. When the second drive motor 320 rotates, it drives the rotating ring 301 to rotate, thereby driving the multiple second stirring shafts 300 to revolve around the first stirring shaft 200.

[0051] In a further embodiment, the rotational speeds of the first drive motor 220 and the second drive motor 320 are adjustable, so that the speeds of the rotation of the first stirring shaft 200 and the revolution of the second stirring shaft 300 are different. When the rotation speed of the first stirring shaft 200 and the revolution speed of the second stirring shaft 300 are different, the area in which the first stirring shaft 200 and the second stirring shaft 300 push the pulp to move upward will change. For example, when the rotation speed of the first stirring shaft 200 increases and the revolution speed of the second stirring shaft 300 decreases, the area where the pulp is driven to rise from the bottom by the first stirring blade 210 on the first stirring shaft 200 increases, and the area where the pulp is driven to rise from the bottom by the second stirring blade 310 decreases, that is, the area where the pulp is driven to rise on the bottom surface by the first stirring shaft 200 is a circular area, and after the rotation speed increases, the radius of the circular area increases, while the area where the pulp is driven to rise on the bottom surface by the second stirring shaft 300 is an annular area, and after the rotation speed decreases, the radius of the annular area decreases, thereby causing the critical point of the pulp driven by the first stirring shaft 200 and the pulp driven by the second stirring shaft 300 to move in the radial direction within the shell 100 toward the direction close to the second stirring shaft 300.

[0052] Similarly, the rotation speed of the first stirring shaft 200 decreases, while the revolution speed of the second stirring shaft 300 increases, the area where the pulp is driven to rise from the bottom by the first stirring blade 210 on the first stirring shaft 200 decreases, and the area where the pulp is driven to rise from the bottom by the second stirring blade 310 increases, so that the critical point of the pulp moves in the radial direction of the shell 100 toward the first stirring shaft 200. Therefore, multiple time intervals can be set, and the rotation speed of the first drive motor 220 and the second drive motor 320 is adjusted in each time interval, so that the critical point of the pulp reciprocates in the radial direction of the shell 100, further improving the stirring and mixing of the pulp by the first stirring shaft 200 and the second stirring shaft 300, so that the mixing of the pulp is more uniform.

[0053] In a further embodiment, the first stirring blades 210 on the first stirring shaft 200 can move along the radial direction of the first stirring shaft 200, so that the distance between the first stirring blades 210 and the axis of the first stirring shaft 200 gradually increases from bottom to top on the first stirring shaft 200, forming a cone-like shape with the small end facing downward, so that the first stirring shaft 200 can gradually push the pulp toward the edge of the shell 100 when rotating; and the plurality of second stirring blades 310 on the second stirring shaft 300 can move along the radial direction of the second stirring shaft 300, so that the distance between the second stirring blades 310 and the axis of the second stirring shaft 300 gradually increases from bottom to top on the first stirring shaft 200. When the second stirring shaft 300 revolves, the pulp stirred by the second stirring blades 310 forms a similar cone, and the second stirring blades 310 can push the pulp obliquely upward, that is, the pulp gradually tilts toward the direction close to the first stirring shaft 200.

[0054] The first stirring blade 210 and the second stirring blade 310 are both provided with pressure sensors. When the mixture in the shell 100 is uniform, the pressures of the pulp received by the pressure sensors on the first stirring blade 210 and the second stirring blade 310 are the same. If the pressures of the pulp received by the pressure sensors on the first stirring blade 210 and the second stirring blade 310 are different, for example, the pressure of the pulp received by the first stirring blade 210 increases, while the pressure of the pulp received by the second stirring blade 310 decreases, it means that the pulp concentration near the center of the shell 100 is larger, while the pulp concentration near the edge of the shell 100 is smaller. At this time, the first stirring blade 210 on the first stirring shaft 200 starts to move along the radial direction of the first stirring shaft 200, so that the first stirring blade 210 forms a cone-like shape. When the first stirring shaft 200 rotates, the pulp with a larger concentration near the center of the shell 100 can be pushed obliquely upward, and the inclination direction is from the shell 10 0 is inclined from the bottom center to the edge close to the top of the shell 100, so that the pulp can flow toward the edge of the shell 100, thereby making the pulp concentration at the edge and the center of the shell 100 uniform; similarly, if the pressure of the pulp received by the pressure sensor on the second stirring blade 310 increases, while the pressure of the pulp received by the first stirring blade 210 decreases, it means that the pulp concentration at the edge of the shell 100 is greater than the pulp concentration at the center of the shell 100. At this time, the second stirring blade 310 on the second stirring shaft 300 will move along the radial direction of the second stirring shaft 300, and the second stirring shaft 300 will push the pulp at the edge of the shell 100 obliquely upward when it revolves. The inclination direction is from the bottom edge of the shell 100 to the center close to the top of the shell 100, so that the pulp with a higher concentration at the edge of the shell 100 can flow to the center of the shell 100, thereby making the pulp concentration at the edge and the center of the shell 100 uniform, thereby ensuring uniform mixing of the pulp.

[0055] Specifically, the first stirring shaft 200 and the second stirring shaft 300 are both hollow inside, a first tapered rod 240 is provided in the first stirring shaft 200, and a second tapered rod 340 is provided in the second stirring shaft 300, the tips of the first tapered rod 240 and the second tapered rod 340 are both facing downward, and the first tapered rod 240 can move along the axial direction of the first stirring shaft 200 so that the conical surface of the first tapered rod 240 contacts with a plurality of first stirring blades 210, thereby pushing the first stirring blades 210 to move radially along the first stirring shaft 200. The conical surface of the conical rod makes the first stirring blades 210 gradually move away from the axis of the first stirring shaft 200 from bottom to top; and the second conical rod 340 can move along the axial direction of the second stirring shaft 300 so that the conical surface of the second conical rod 340 contacts the second stirring blades 310, thereby pushing the second stirring blades 310 to move radially along the second stirring shaft 300, and the conical surface of the second conical rod 340 makes the second stirring blades 310 gradually move away from the axis of the second stirring shaft 300 from bottom to top.

[0056] It should be noted that the structure for realizing the above functions is not limited to the structure in the present embodiment, and other structures may be used, for example, a telescopic rod is provided on each of the first stirring blades 210 and the second stirring blades 310, and the radial movement of the first stirring blades 210 and the second stirring blades 310 on the first stirring shaft 200 and the second stirring shaft 300 is controlled by the telescopic rod. Of course, other structures may also be used, which will not be described in detail here.

[0057] Specifically, a first telescopic member 230 is provided on the shell 100, and the first telescopic member 230 controls the first conical rod 240 to move axially within the first stirring shaft 200. The fixed end of the first telescopic member 230 is connected to the shell 100, and the telescopic end of the first telescopic member 230 is connected to the first conical rod 240. When the first telescopic member 230 is extended, it pushes the first conical rod 240 to move axially along the first stirring shaft 200, and the first telescopic member 230 is reset when it is shortened.

[0058] Specifically, a second telescopic member 330 is also provided on the shell 100, and the second telescopic member 330 is used to control the axial movement of the second conical rod 340 in the second stirring shaft 300. A connecting ring 341 is provided in the shell 100, and an annular limiting groove 342 is provided on the lower end surface of the connecting ring 341, and multiple second conical rods 340 are slidably set in the annular limiting groove 342. Multiple second conical rods 340 can slide in the annular limiting groove 342 but do not separate from the annular limiting groove 342. The upper end surface of the connecting ring 341 is connected to the second telescopic member 330. When the second telescopic member 330 is extended or retracted, it drives the connecting ring 341 to move axially along the second stirring shaft 300, that is, the connecting ring 341 drives the multiple second conical rods 340 to move synchronously so that the multiple second conical rods 340 move axially along the second stirring shaft 300.

[0059] It should be noted that the first telescopic member 230 and the second telescopic member 330 mentioned above can be telescopic cylinders, hydraulic cylinders, electrically controlled push rods, etc., which are not specifically limited here.

[0060] Specifically, Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, an elastic member 430 is provided at the connection between the first stirring blade 210 and the second stirring blade 310 and the first stirring shaft 200 and the second stirring shaft 300 , and the elastic member 430 can reset the first stirring blade 210 and the second stirring blade 310 .

[0061] To facilitate connection, the first stirring blade 210 and the second stirring blade 310 are both provided with a connecting shaft 410, and a limiting block 420 is provided on the connecting shaft 410. The first stirring shaft 200 and the second stirring shaft 300 are both provided with a connecting hole 400, and a strip limiting groove 440 is provided on the inner circumference of the connecting hole 400. The connecting shaft 410 of the first stirring blade 210 and the second stirring blade 310 is slidingly sealed and arranged in the connecting hole 400. The limiting block 420 and the strip limiting groove 440 limit the first stirring blade. The first stirring blade 210 and the second stirring blade 310 rotate, but the limit block 420 does not limit the radial movement of the first stirring blade 210 and the second stirring blade 310 along the first stirring shaft 200 and the second stirring shaft 300, and the elastic member 430 is sleeved on the connecting shaft 410, so that when the first stirring blade 210 and the second stirring blade 310 are separated from the conical surface of the first conical rod 240 and the second conical rod 340, the first stirring blade 210 and the second stirring blade 310 can be reset under the action of the elastic member 430.

[0062] It can be understood that the elastic member 430 mentioned above can be an elastic component such as a spring.

[0063] The specific working process of the impregnated pulp processing stirring device provided by the present application is described below in combination with the above embodiments:

[0064] Feed:

[0065] Water and pulp stock are added into the housing 100 from the feed port 120 .

[0066] start up:

[0067] The first drive motor 220 and the second drive motor 320 are started. The first drive motor 220 directly drives the first stirring shaft 200 to rotate. The second drive motor 320 drives the rotating ring 301 to rotate. The rotating ring 301 drives multiple second stirring shafts 300 to revolve around the first stirring shaft 200. The first stirring blade 210 on the first stirring shaft 200 and the second stirring blade 310 on the second stirring shaft 300 both push the pulp at the bottom upward. Since the first stirring blade 210 on the first stirring shaft 200 and the second stirring blade 310 on the second stirring shaft 300 are inclined in opposite directions, the stirring and mixing effect of the pulp is better. The rotation directions of the first stirring shaft 200 and the second stirring shaft 300 are opposite, so that the flow speed of the pulp is greatly different from the rotation speed of the first stirring shaft 200 and the second stirring shaft 300. The pulp is broken up by the first stirring blade 210 and the second stirring blade 310, and the mixing degree of the pulp is more uniform.

[0068] The rotation speed of the first drive motor 220 and the second drive motor 320 are adjusted regularly to change the speed of rotation of the first stirring shaft 200 and the revolution of the second stirring shaft 300, so that the critical points of the pulp driven by the first stirring shaft 200 and the pulp driven by the second stirring shaft 300 continuously move in the radial direction of the shell 100, thereby further improving the stirring and mixing degree of the pulp. If the pulp is unevenly mixed during the stirring and mixing process, the pressure sensors on the first stirring blade 210 and the second stirring blade 310 can sense the uneven mixing.

[0069] When the pulp concentration at the edge of the shell 100 is greater than the pulp concentration at the center of the shell 100:

[0070] The force of the pulp on the pressure sensor of the second stirring blade 310 increases, indicating that the pulp concentration at the edge of the shell 100 is greater than the pulp concentration at the center of the shell 100, and the second telescopic member 330 begins to extend. The extension of the second telescopic member 330 drives the connecting ring 341 to move downward in the shell 100, and the connecting ring 341 drives the plurality of second tapered rods 340 to move downward along the axial direction in the second stirring shaft 300. The tapered surface of the second tapered rod 340 is in contact with the connection of the plurality of second stirring blades 310 to push the plurality of second stirring blades 310, so that The plurality of second stirring blades 310 move radially along the second stirring shaft 300, and the distance between the second stirring blades 310 and the axis of the second stirring shaft 300 increases gradually from bottom to top, thereby forming a cone-like shape with the small end facing downward, so that when the second stirring shaft 300 revolves, the second stirring blades 310 push the pulp with a higher concentration at the edge of the shell 100 obliquely upward, so that the pulp with a higher concentration at the edge of the shell 100 gradually flows toward the center of the shell 100 so that the pulp concentration distribution in the shell 100 gradually becomes uniform, thereby improving the mixing efficiency of the pulp. After the pulp concentration is uniformly distributed, the second telescopic member 330 is reset and then drives the plurality of second tapered rods 340 to reset. After the second tapered rods 340 are reset, the connecting shafts 410 of the plurality of second stirring blades 310 are separated from the tapered surface of the second tapered rod 340, and the plurality of second stirring blades 310 are reset under the action of the elastic member 430.

[0071] When the pulp concentration at the edge of the shell 100 is less than the pulp concentration at the center of the shell 100:

[0072] The force exerted by the pulp on the pressure sensor of the first stirring blade 210 increases, indicating that the pulp concentration at the center of the shell 100 is greater than the pulp concentration at the edge of the shell 100, and the first telescopic member 230 begins to extend, and the first telescopic member 230 drives the first conical rod 240 to move downward along the axial direction of the first stirring shaft 200 so that the conical surface of the first conical rod 240 contacts the connecting shafts 410 of the first stirring blades 210, thereby causing the first stirring blades 210 to move radially along the first stirring shaft 200, and the distance of the first stirring blades 210 from the axis of the first stirring shaft 200 gradually increases from bottom to top, forming a cone-like shape with the small end facing downward. When the first stirring shaft 200 rotates, the first stirring blades 210 push the pulp at the center of the shell 100 obliquely upward, and gradually flow toward the edge of the shell 100, thereby making the pulp concentration inside the shell 100 evenly distributed, thereby improving the stirring and mixing efficiency of the pulp. After the pulp concentration is evenly distributed, the first telescopic member 230 is reset and then drives the first conical rod 240 to reset. After the first conical rod 240 is reset, the connecting shafts 410 of the first mixing blades 210 are separated from the conical surface of the first conical rod 240, and the first mixing blades 210 are reset under the action of the elastic member 430.

[0073] Nesting:

[0074] After the pulp is evenly mixed, the discharge port 130 is opened, and the pulp is discharged from the housing 100 through the discharge port 130 .
