[0032] Compared with the prior art, the beneficial effects of this application are:
[0033] When preparing slurry through the slurry making equipment, since a raw material inlet connected to the dispersive stirring chamber is provided on the barrel wall of the mixing barrel, the raw material can be firstly added into the dispersive stirring chamber through the raw material inlet, and after the raw material enters the dispersive stirring chamber, since the front push component and the rear push component are both provided in the dispersive stirring chamber, the raw material can be pushed toward the direction close to the rear push component by the front push component, and at the same time, the raw material can be pushed toward the front push component by the rear push component, so that a strong collision can occur between the raw material pushed by the front push component and the raw material pushed by the rear push component, and in the process of continuous collision of the raw materials, the raw materials can be crushed, dispersedly mixed to form slurry, thereby achieving the purpose of preparing slurry through raw materials.

[0056] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.
[0057] See also Figure 1 and Figure 2 The pulping equipment 100 comprises: a stirring barrel 1 and a dispersive stirring assembly 2, wherein Figure 2 , Figure 3 and Figure 4The mixing barrel 1 has a dispersive mixing chamber 11. A raw material inlet 12 connected to the dispersive mixing chamber 11 is arranged on the barrel wall of the mixing barrel 1. The raw material inlet 12 is used to supply raw materials into the dispersive mixing chamber 11 through the raw material inlet 12. Figure 2 The dispersive stirring assembly 2 is disposed in the dispersive stirring chamber 11, and includes a forward pushing assembly 21 and a rearward pushing assembly 22. The forward pushing assembly 21 is used to move toward the direction close to the rearward pushing assembly 22 ( Figure 2 The negative direction of the X-axis) pushes the raw material, and the rear push component 22 is used to move toward the direction close to the front push component 21 ( Figure 2 The raw materials are pushed in the positive direction of the X-axis to make them collide and mix to form a slurry.
[0058] In this embodiment, when preparing slurry through the pulping equipment 100, since a raw material inlet 12 connected to the dispersive stirring chamber 11 is provided on the barrel wall of the mixing barrel 1, the raw material can be first added into the dispersive stirring chamber 11 through the raw material inlet 12. After the raw material enters the dispersive stirring chamber 11, since the front push component 21 and the rear push component 22 are both provided in the dispersive stirring chamber 11, the raw material can be pushed toward the direction of the rear push component 22 by the front push component 21. At the same time, the raw material can be pushed toward the front push component 21 by the rear push component 22. In this way, a strong collision can occur between the raw material pushed by the front push component 21 and the raw material pushed by the rear push component 22. In the process of continuous collision of the raw materials, the raw materials can be crushed, dispersedly mixed to form slurry, thereby achieving the purpose of preparing slurry through raw materials.
[0059] It can be seen that the raw materials are mixed to form slurry by pushing the raw materials in the direction close to each other by the forward push component 21 and the rear push component 22, so that the raw materials collide with each other and mix evenly, thereby achieving the purpose of preparing slurry. The entire raw material mixing process is not carried out by stirring, but by collision dispersion mixing. Compared with the mixing method by stirring in the related art, since the collision dispersion mixing method does not have a stirring dead angle, the uniformity of the raw material mixing can be improved to a certain extent.
[0060] In addition, the collision dispersive mixing method does not require friction between screws to achieve mixing of raw materials. Therefore, compared with the screw mixing method, the collision dispersive mixing method does not require friction between screws. Therefore, on the one hand, the heat generated by the pulping equipment 100 during the pulping process can be reduced. On the other hand, since the screws require precise matching and are relatively expensive, the cost of the pulping equipment 100 can be reduced.
[0061] Among them, the above-mentioned raw materials may refer to one or more of active substances, conductive agents, dispersants, binders, additives, etc. Of course, based on different application scenarios, the above-mentioned raw materials may also be other possible substances. This embodiment does not limit the raw materials.
[0062] In some embodiments, see Figure 2 and Figure 4 A slurry outlet 13 connected to the dispersive stirring chamber 11 is also provided on the barrel wall of the mixing barrel 1. The raw material inlet 12 and the slurry outlet 13 are located at both ends of the mixing barrel 1 along the first direction F1. The front push component 21 and the rear push component 22 are arranged along the first direction F1 and are located between the slurry outlet 13 and the raw material inlet 12 along the first direction F1. The forward thrust of the front push component 21 on the raw material is greater than the rear thrust of the rear push component 22 on the raw material, so as to push the slurry out of the dispersive stirring chamber 11 through the slurry outlet 13.
[0063] Since the forward thrust of the front push component 21 on the raw material is greater than the backward thrust of the rear push component 22 on the raw material, although the rear push component 22 can push the raw material in the direction close to the front push component 21, the raw material as a whole still flows in the direction from the front push component 21 to the rear push component 22. On this basis, since the raw material inlet 12 and the slurry outlet 13 are located at both ends of the mixing barrel 1 along the first direction F1, the front push component 21 and the rear push component 22 are arranged along the first direction F1 and are located between the slurry outlet 13 and the raw material inlet 12 along the first direction F1. Therefore, under the action of the front push component 21 and the rear push component 22, the raw material as a whole will flow from the raw material inlet 12 to the slurry outlet 13. Directional flow allows the raw material to flow smoothly from the raw material inlet 12 to the slurry outlet 13 under the pushing action of the forward pushing component 21, thereby allowing the slurry to be pushed out of the dispersive stirring chamber 11 more smoothly through the slurry outlet 13. The forward pushing force of the forward pushing component 21 on the raw material can be fully utilized to push the slurry out of the dispersive stirring chamber 11, thereby avoiding the need to set up a structure specifically for pushing the slurry out of the dispersive stirring chamber 11. In addition to causing the raw materials to collide and mix, the forward pushing component 21 can also push the slurry out of the dispersive stirring chamber 11, making the structure of the entire pulping equipment 100 more concise.
[0064] In some embodiments, see Figure 4 , the volume of the dispersive stirring chamber 11 gradually decreases along the first direction F1. By gradually decreasing the volume of the dispersive stirring chamber 11 along the first direction F1, the flow rate of the raw material along the first direction F1 can be gradually increased. As the flow rate gradually increases, the frequency of the raw materials colliding with each other can be made higher and higher, so that the raw materials can be better dispersed, and the raw materials can be mixed more evenly.
[0065] The annular shape of the dispersive stirring chamber 11 may be an annular structure or other possible shapes. The present embodiment does not limit the shape of the dispersive stirring chamber 11.
[0066] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The dispersive stirring component 2 also includes: a first rotating driving member 23 and a first rotating member 24, wherein the first rotating member 24 is rotatably disposed in the dispersive stirring chamber 11, the front pushing component 21 and the rear pushing component 22 are both disposed on the first rotating member 24, the first rotating driving member 23 is used to drive the first rotating member 24 to rotate, and when the first rotating member 24 drives the front pushing component 21 to rotate, it pushes the raw material toward the direction of the rear pushing component 22, and when the first rotating member 24 drives the rear pushing component 22 to rotate, it pushes the raw material toward the direction of the front pushing component 21.
[0067] Since the first rotating member 24 is rotatably disposed in the dispersive stirring chamber 11, and the front push assembly 21 and the rear push assembly 22 are both disposed on the first rotating member 24, when the first rotating driving member 23 drives the first rotating member 24 to rotate, the front push assembly 21 and the rear push assembly 22 disposed on the first rotating member 24 can be synchronously driven to rotate synchronously. When the front push assembly 21 rotates, it can play a role in pushing the raw material in the direction close to the rear push assembly 22, and when the rear push assembly 22 rotates, it can play a role in pushing the raw material in the direction close to the front push assembly 21. The way in which the front push assembly 21 pushes the raw material in the direction close to the rear push assembly 22 is very simple, and the way in which the rear push assembly 22 pushes the raw material in the direction close to the front push assembly 21 is also very simple. Therefore, it can simplify the structure of the dispersive stirring assembly 2 and reduce the cost of the dispersive stirring assembly 2.
[0068] In addition, it can be understood that the front push component 21 can also play a role in stirring the raw materials during the process of following the rotation of the first rotating member 24, and the rear push component 22 can also play a role in stirring the raw materials during the process of following the rotation of the first rotating member 24. That is, in addition to causing the raw materials to collide with each other and dispersedly mix the raw materials, the front push component 21 and the rear push component 22 can also play a role in stirring and mixing the raw materials, thereby making the raw materials mixed more evenly.
[0069] It should be noted that the first rotating drive member 23 may include but is not limited to a motor, and the first rotating member 24 may include but is not limited to a barrel-shaped structure. This embodiment does not limit the first rotating drive member 23 and the first rotating member 24.
[0070] In some embodiments, see Figure 2 and Figure 6The number of the front push assembly 21 and the number of the rear push assembly 22 are both multiple, and the multiple front push assemblies 21 and the multiple rear push assemblies 22 are all along the axial direction of the first rotating member 24 ( Figure 2 The front push assembly 21 and the rear push assembly 22 are arranged in an array in sequence along the axial direction ( Figure 6 The X-axis direction) is staggered.
[0071] By making the number of the front push components 21 and the rear push components 22 both multiple and making the front push components 21 and the rear push components 22 staggered along the axial direction of the first rotating member 24, the raw materials can be subjected to multiple collisions under the action of the multiple front push components 21 and the multiple rear push components 22, so that the raw materials can be better collided and mixed evenly.
[0072] Specifically, the number of the front push components 21 can be eight. Of course, the number of the front push components 21 can also be other numbers, for example, the number of the front push components 21 can also be six or seven, etc., and this embodiment does not limit the number of the front push components 21. Correspondingly, the number of the rear push components 22 can also be six, seven or eight, etc., and this embodiment does not limit the number of the rear push components 22.
[0073] In some embodiments, see Figure 2 and Figure 6 The forward push component 21 includes a plurality of first flat blades 211, and the plurality of first flat blades 211 are arranged in an array spaced apart along the circumference of the first rotating member 24. Since the plurality of first flat blades 211 are arranged in an array spaced apart along the circumference of the first rotating member 24, when the first rotating member 24 rotates around its own axial direction, the plurality of first flat blades 211 can be synchronously driven to rotate around the axial direction of the first rotating member 24. During the rotation of the plurality of first flat blades 211, the raw materials can be stirred and pushed toward the direction close to the backward push component 22.
[0074] Since the first flat blade 211 has a simple structure and is easy to process, the cost of the forward push assembly 21 can be reduced.
[0075] At the same time, during the rotation of the plurality of first flat blades 211 , the raw materials between the first flat blades 211 and the cavity wall of the dispersive stirring cavity 11 can be subjected to a strong shear force, thereby further mixing the raw materials more evenly.
[0076] Similarly, the rear push assembly 22 includes a plurality of second flat blades 221, and the plurality of second flat blades 221 are arranged in an array along the circumferential direction of the first rotating member 24. When the rear push assembly 22 includes a plurality of second flat blades 221, its structure may be the same or similar to the structure of the front push assembly 21 including a plurality of first flat blades 211, and may bring the same or similar beneficial effects. For details, reference may be made to the description of the front push assembly 21 in the above embodiment, and this embodiment will not be repeated here.
[0077] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The width direction of the first flat blade 211 is perpendicular to the peripheral wall of the first rotating member 24, and the angle between the extension direction of the first flat blade 211 and the circumference of the first rotating member 24 is a first angle a1. The width direction of the second flat blade 221 is perpendicular to the peripheral wall of the first rotating member 24, and the angle between the extension direction of the second flat blade 221 and the circumference of the first rotating member 24 is a second angle a2. The first angle a1 is greater than the second angle a2 and the length of the first flat blade 211 is greater than the length of the second flat blade 221.
[0078] Since the first angle a1 is greater than the second angle a2 and the length of the first flat blade 211 is greater than the length of the second flat blade 221, the forward thrust of the first flat blade 211 pushing the raw material toward the second flat blade 221 can be greater than the backward thrust of the second flat blade 221 pushing the raw material toward the first flat blade 211, thereby achieving the purpose of allowing the raw material as a whole to flow in the direction pointed by the forward push component 21 to the backward push component 22.
[0079] Of course, the purpose of making the forward thrust of the first flat blade 211 pushing the raw material toward the second flat blade 221 greater than the backward thrust of the second flat blade 221 pushing the raw material toward the first flat blade 211 can also be achieved in other ways. For example, it can also be achieved by making the width of the first flat blade 211 greater than the width of the second flat blade 221. This embodiment is not limited to this.
[0080] In some embodiments, see Figure 7 , the projection of the first flat blade 211 along its own extension direction ( Figure 7 The projection of the first flat blade 211 along its extension direction is located on the second flat blade 221, so that the first flat blade 211 can guide the raw material to the second flat blade 221 and collide with the second flat blade 221, so that large particles in the raw material can be crushed, and the raw material can be mixed more evenly.
[0081] Further, in some embodiments, see Figure 7 , the projection of the second flat blade 221 along its own extension direction ( Figure 7 The projection of the second flat blade 221 along its extension direction is located on the first flat blade 211, so that the second flat blade 221 can guide the raw material to the first flat blade 211 and collide with the first flat blade 211, so that large particles in the raw material can be crushed, and the raw material can be mixed more evenly.
[0082] In some embodiments, see Figure 6 and Figure 7 The dispersive stirring component 2 also includes: an annular blade 25, which is annularly mounted on the first rotating member 24 and has a gap 251 between the annular blade 25 and the peripheral wall of the first rotating member 24; a first flat blade 211 is located on both sides of the annular blade 25 along the width direction of the first flat blade 211, so that part of the structure of the first flat blade 211 is located in the gap 251 and the remaining part of the structure extends out of the gap 251 along the width direction of the first flat blade 211; and a second flat blade 221 is located on both sides of the annular blade 25 along the width direction of the second flat blade 221, so that part of the structure of the second flat blade 221 is located in the gap 251 and the remaining part of the structure extends out of the gap 251 along the width direction of the second flat blade 221.
[0083] Since the annular blade 25 is sleeved on the first rotating member 24, when the first rotating member 24 rotates, the annular blade 25 can be driven to rotate together. When the annular blade 25 rotates, the speed difference between the annular blade 25 and the cavity wall of the dispersive stirring chamber 11 causes the raw materials to be subjected to a strong shearing effect, so that the raw materials can be mixed more evenly.
[0084] In addition, since the annular blade 25 is ringed on the first rotating member 24 and has a gap 251 between the annular blade 25 and the peripheral wall of the first rotating member 24, the annular blade 25 can divide the dispersive stirring chamber 11 into a space on the side close to the peripheral wall of the first rotating member 24 and a space on the side close to the chamber wall of the dispersive stirring chamber 11, so that the dispersive stirring chamber 11 is divided into smaller parts, thereby preventing large pieces of raw materials from passing through the dispersive stirring chamber 11 and flowing out of the dispersive stirring chamber 11 through the slurry outlet 13.
[0085] In addition, by locating the first flat blade 211 on both sides of the annular blade 25 along the width direction of the first flat blade 211, the upper first flat blade 211 can play a role in stirring the raw materials on both sides of the annular blade 25 along the width direction of the first flat blade 211, thereby making the raw materials mixed more evenly.
[0086] Similarly, by locating the second flat blade 221 on both sides of the annular blade 25 along the width direction of the second flat blade 221, the upper second flat blade 221 can play a role in stirring the raw materials on both sides of the annular blade 25 along the width direction of the second flat blade 221, thereby making the raw materials mixed more evenly.
[0087] In some embodiments, see Figure 2 and Figure 4 The mixing barrel 1 also has a pre-mixing chamber 14 connected to the dispersive mixing chamber 11. The pulping equipment 100 also includes a pre-mixing component 3, which is located in the pre-mixing chamber 14. The pre-mixing component 3 is used to pre-mix the raw materials entering the pre-mixing chamber 14 through the raw material inlet 12 and then push them into the dispersive mixing chamber 11.
[0088] Since the pre-stirring chamber 14 is connected with the dispersive stirring chamber 11, and the pre-stirring assembly 3 is located in the pre-stirring chamber 14, after the raw materials enter the pre-stirring chamber 14 through the raw material inlet 12, the pre-stirring assembly 3 can pre-mix the raw materials in the pre-stirring chamber 14, and push the raw materials into the dispersive stirring chamber 11 after pre-mixing. In this way, the raw materials can be pre-mixed before entering the dispersive stirring chamber 11, so that the raw materials can be collided and dispersedly mixed more evenly when entering the dispersive stirring chamber 11.
[0089] In some embodiments, see Figure 1 and Figure 2 The pre-stirring assembly 3 includes: a second rotating driving member 31, a second rotating member 32, a first blade 33, a second blade 34 and a third blade 35, wherein the second rotating member 32 is rotatably disposed in the pre-stirring chamber 14, and the first blade 33, the second blade 34 and the third blade 35 are arranged along the axial direction of the second rotating member 32 ( Figure 2 The second rotating member 32 is sequentially arranged in the X-axis direction, and the second rotating driving member 31 is used to drive the second rotating member 32 to rotate. When the second rotating member 32 drives the first blade 33 to rotate, it moves toward the direction close to the second blade 34 ( Figure 2 The second rotating member 32 drives the second blade 34 to rotate in a direction close to the third blade 35 ( Figure 2 The second rotating member 32 drives the third blade 35 to rotate to push the raw material into the dispersive stirring chamber 11.
[0090] Since the second rotating member 32 is rotatably arranged in the pre-mixing chamber 14, the first blade 33, the second blade 34 and the third blade 35 are sequentially arranged on the second rotating member 32 along the axial direction of the second rotating member 32. Therefore, when the second rotating driving member 31 drives the second rotating member 32 to rotate, the second rotating member 32 can synchronously drive the first blade 33, the second blade 34 and the third blade 35 arranged thereon to rotate. During the rotation of the first blade 33, the purpose of pushing the raw material toward the direction close to the second blade 34 can be achieved. During the rotation of the second blade 34, the purpose of pushing the raw material toward the direction close to the third blade 35 can be achieved. During the rotation of the third blade 35, the purpose of pushing the raw material into the dispersive mixing chamber 11 can be achieved.
[0091] It can be seen that the raw materials are pushed into the dispersive stirring chamber 11 after passing through the first blade 33, the second blade 34 and the third blade 35 in sequence. In the process of passing through the first blade 33, the second blade 34 and the third blade 35, the raw materials will be stirred by the first blade 33, the second blade 34 and the third blade 35, so that the raw materials are pre-mixed, and the raw materials pushed into the dispersive stirring chamber 11 can be mixed more evenly.
[0092] The second rotating driving member 31 may include but is not limited to a motor, which is not limited in this embodiment.
[0093] In some instances, see Figure 2 , the blade extension direction of the first blade 33 is in line with the axial direction of the second rotating member 32 ( Figure 2 The third blade 35 has an angle with the axial direction of the second rotating member 32, the blade extension direction of the third blade 35 has an angle with the axial direction of the second rotating member 32, and the blade extension direction of the second blade 34 is parallel to the axial direction of the second rotating member 32. In this way, when the raw material flows from the first blade 33 to the second blade 34 and then to the third blade 35, the raw material will be subjected to collision, shearing and friction from blades with different inclination angles. In this way, on the one hand, large particles in the raw material can be better crushed, and on the other hand, the raw material can be better mixed.
[0094] The angle between the blade extension direction of the first blade 33 and the axial direction of the second rotating member 32 may be 30°, 35° or 40°, etc., which is not limited in this embodiment. Similarly, the angle between the blade extension direction of the third blade 35 and the axial direction of the second rotating member 32 may also be 30°, 35° or 40°, etc., which is not limited in this embodiment.
[0095] In some embodiments, see Figure 2, the blade of the second blade 34 is a grille-shaped blade. When the blade of the second blade 34 is a grille-shaped blade, during the rotation of the second blade 34, the raw material can also flow from one side of the blade of the second blade 34 to the other side through the grille holes on the grille-shaped blade. During the flow of the raw material, the raw material can further collide and rub with the blade, thereby making the raw material mixed more evenly.
[0096] The shape of the grille holes may be rectangular, circular or any other possible shape, and the shape of the grille holes is not limited in this embodiment.
[0097] In some embodiments, see Figure 2 , Figure 4 and Figure 8 The mixing barrel 1 also has a cross flow channel 15, the pre-mixing chamber 14 is connected to the dispersive mixing chamber 11 through the cross flow channel 15, and the extension directions of the individual flow channels in the cross flow channel 15 are different from each other. The pre-mixing component 3 is used to pre-mix the raw materials entering the pre-mixing chamber 14 through the raw material inlet 12 and then push them into the dispersive mixing chamber 11 through the cross flow channel 15.
[0098] Since the cross flow channel 15 has a flow channel intersection position, and the extension directions of individual flow channels in the cross flow channel 15 are different from each other, in the process of the raw materials passing through the cross flow channel 15, the raw materials in different individual flow channels will form strong collisions and impacts at the flow channel intersection position. Such collisions and impacts will cause the raw materials to form a strong turbulence effect in the cross flow channel 15, thereby allowing the raw materials to be further distributed and mixed.
[0099] In some embodiments, the dispersive stirring chamber 11 is arranged closer to the barrel wall of the stirring barrel 1 than the center of the stirring barrel 1, and / or the pre-stirring chamber 14 is arranged closer to the barrel wall of the stirring barrel 1 than the center of the stirring barrel 1, and / or the cross flow channel 15 is arranged closer to the barrel wall of the stirring barrel 1 than the center of the stirring barrel 1.
[0100] By arranging the dispersive stirring chamber 11 close to the barrel wall of the mixing barrel 1, the heat generated by pulping in the dispersive stirring chamber 11 can be easily transferred out of the dispersive stirring chamber 11 through the barrel wall, thereby avoiding overheating of the pulping equipment 100.
[0101] Similarly, by arranging the pre-mixing chamber 14 and the cross flow channel 15 close to the barrel wall of the mixing barrel 1, the heat in the pre-mixing chamber 14 and the cross flow channel 15 can be quickly transferred out of the mixing barrel 1, thereby avoiding overheating of the pulping equipment 100.
