Description

Technical Field

[0001] The utility model belongs to the technical field of solid-liquid mixing devices, and particularly relates to a horizontal pulping device. Background Art

[0002] Existing pulping machines have a mixing chamber, a liquid material chamber, and a powder material chamber. The powder enters the mixing chamber from the powder material chamber, and the liquid enters the mixing chamber from the liquid material chamber. The powder and the liquid are finally mixed in the mixing chamber to form a slurry. At present, the powder entering the mixing chamber is not fine enough, and caking is likely to occur. Not only in the mixing chamber, a greater shearing force is required to break up the caked powder, but also when the caked powder is mixed with the liquid during the powder-liquid mixing process, a colloidal kneaded product is easily formed.

[0003] Due to the fact that in the prior art, the powder is prone to form a colloidal kneaded product in the powder material chamber, resulting in accumulation and caking, which affects the uniformity of the slurry and also prolongs the powder-liquid mixing time. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: aiming at the problem that the existing pulping machine is prone to form a colloidal kneaded product in the powder material chamber, resulting in accumulation and caking, affecting the uniformity of the slurry and prolonging the powder-liquid mixing time, a horizontal pulping device is provided.

[0005] To solve the above technical problem, an embodiment of the utility model provides a horizontal pulping device, which includes a housing, a rotating shaft, a rotor, a rod pin dispersing group, and a stator. The housing is provided with an inner cavity, the stator is fixed in the inner cavity, the rotor is arranged inside the stator in the radial direction, an inner wall of the stator, an end face of the rotor along a first direction, and an inner wall of the housing enclose a powder material chamber, and the rotating shaft is connected to the rotor;

[0006] The rod pin dispersing group is arranged at one end of the rotor along the first direction, the rod pin dispersing group can extend into the powder material chamber along the first direction, and the rod pin dispersing group is used for dispersing the materials in the powder material chamber; the first direction is parallel to the central axis of the stator.

[0007] Optionally, a plurality of rod pin dispersing groups are provided, and the plurality of rod pin dispersing groups are spaced apart from inside to outside along the radial direction of the rotor.

[0008] Optionally, the rod pin dispersing group includes a plurality of rod pins, one end of each rod pin is fixed on the rotor, the other end of each rod pin extends into the powder material chamber along the first direction, and the plurality of rod pins are uniformly arranged around the central axis of the rotor.

[0009] Optionally, all the rod pins in the rod pin breaking group that are located at the same radial dimension on the rotor have the same length, and the lengths of the rod pins in the rod pin breaking group that are located at different radial dimensions on the rotor decrease from the inside to the outside along the radial direction of the rotor.

[0010] Optionally, the pins in the pin-scrambling group that are located on the rotor in different radial sizes are staggered in both the radial and circumferential directions of the end surface of the rotor.

[0011] Optionally, the number of rod pins contained in the rod pin breaking group at different radial dimensions on the rotor is different, and the number of the rod pins gradually increases from the inside to the outside along the radial direction of the rotor.

[0012] Optionally, the rod pin is cylindrical, and is cut to form two oppositely disposed notches, and the two notches are used for a wrench to clamp the rod pin.

[0016] According to the horizontal pulping device of the embodiment of the utility model, a rod pin is arranged on the rotor. When the rotating shaft drives the rotor to rotate relative to the stator, a negative pressure is formed in the gap between the rotor and the stator, that is, a negative pressure is formed in the mixing chamber. The negative pressure sucks the liquid in the liquid material chamber toward the mixing chamber, and also sucks the powder in the powder material chamber into the mixing chamber. The rotating shaft also drives the rod pin to rotate, and the powder is broken up and crushed before entering the mixing chamber, and the agglomerated powder is broken in advance before mixing with the liquid, so as to improve the quality of the powder entering the mixing chamber. In this embodiment, the colloid at the junction of the mixing chamber and the powder material chamber is still broken up by the rod pin, and because the crushing effect of the rod pin is better at the high rotation speed of the pulping machine, the agglomerates are broken into powder as much as possible, and the broken materials continue to enter the mixing chamber, thereby reducing the occurrence of blockage of the colloid at the connection between the powder material chamber and the mixing chamber.

Detailed implementation manners

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] As Figures 1 to 4 shown, an embodiment of the present utility model provides a horizontal pulping device, which includes a housing 1, a rotating shaft 2, a rotor 3, a pin dispersing group 5 and a stator 4. The housing 1 is provided with an inner cavity, and the rotating shaft 2, the rotor 3, the pin dispersing group 5 and the stator 4 are all arranged in the housing 1. The rotor 3 is arranged on the inner side in the radial direction of the stator 4, and the rotor 3 and the stator 4 are coaxially arranged. The housing 1 is provided with a discharge port 16, a powder chamber 11, a liquid material chamber 13 and a mixing chamber 12. Among them, the powder chamber 11 is formed by enclosing the inner wall of the stator 4, one end face of the rotor 3 along the first direction and the inner wall of the housing 1. The powder chamber 11 is provided with a powder inlet, and the powder inlet communicates with the outside and the powder chamber 11. The liquid material chamber 13 is provided with a liquid inlet, and the liquid inlet communicates with the outside and the liquid material chamber 13. The powder inlet and the liquid inlet are both arranged on the housing 1. The rotating shaft 2 is coaxially connected to the rotor 3.

[0024] The pin dispersing group 5 is arranged at one end of the rotor 3 along the first direction. The pin dispersing group 5 can extend into the powder chamber 11 along the first direction. The pin dispersing group 5 is used to disperse the materials in the powder chamber 11; the first direction is parallel to the central axis of the stator 4.

[0025] In the prior art, before the powder flows into the mixing chamber 12, caking or granulation may occur. After entering the mixing chamber 12, during the mixing process with the liquid, a colloidal kneaded product is likely to appear, which is not conducive to the mixing of the powder and the liquid. On the one hand, the caked or granular powder will reduce the flow rate of the powder. On the other hand, the colloidal kneaded product is prone to blockage, reducing the mixing efficiency of the powder and the liquid, thus affecting the mixing effect of the slurry. In this embodiment, the rod pin dispersing group 5 is arranged on the rotor 3 and is located on the side of the rotor 3 close to the powder chamber 11. The rod pin dispersing group 5 rotates at a high speed with the rotor 3 and can stir, break and disperse all the powder entering the powder chamber 11 before the powder enters the mixing chamber 12. The pulverized powder can easily enter the mixing chamber 12. By arranging the rod pin dispersing group 5 on the rotor 3, the quality of the powder entering the mixing chamber 12 is improved, the phenomenon of colloid appearing in the mixing chamber 12 is minimized, and the occurrence of colloid blockage in the flow channel is also avoided as much as possible.

[0026] Moreover, the rod pin dispersing group 5 of this embodiment also has a stirring effect, which can stir the powder in the powder chamber 11, drive the movement of the powder in the powder chamber 11, make the powder evenly distributed before entering the mixing chamber 12, reduce the phenomenon of powder bridging, and has a certain effect of guiding the material.

[0027] As an example, a plurality of the rod pin dispersing groups 5 are arranged, and the plurality of rod pin dispersing groups 5 are spaced apart from the inside to the outside along the radial direction of the rotor 3. More specifically, the rod pin dispersing group 5 includes a plurality of rod pins (51, 52), one end of the rod pins (51, 52) is fixed on the rotor 3, the other end of the rod pins (51, 52) extends into the powder chamber 11 along the first direction, and the plurality of rod pins (51, 52) are evenly arranged around the central axis of the rotor 3.

[0028] In this embodiment, the powder chamber 11 is in a conical or frustum shape, the bottom end of the powder chamber 11 is close to the rotor 3, and the top end of the powder chamber 11 is far from the rotor 3, so that the cross-section of the powder chamber 11 gradually increases in the opposite direction of the first direction. In this embodiment, the powder inlet is arranged at the top of the housing 1 or near the top. Under the action of its own weight, the powder moves towards the end face of the rotor 3 through the conical or frustum-shaped powder chamber 11, so that the rod pin dispersing group 5 can fully stir and break the powder in the powder chamber 11 when the rotor 3 rotates at a high speed.

[0029] Further, referring to Figure 2 and Figure 4, all the pin lengths in the pin dispersion group 5 on the rotor 3 at the same radial dimension are the same, that is, on the rotor 3, all the pins 51 have the same radial dimension on the rotor 3. That is to say, for each pin 51 on the rotor 3, the distance from the center of the rotor 3 is the same. All the pins 51 on the rotor 3 have the same length extending along the first direction towards the powder chamber 11. Similarly, on the rotor 3, all the pins 52 also have the same radial dimension on the rotor 3, and the pins 52 also have the same length extending along the first direction. The lengths of the pins in the pin dispersion group 5 on the rotor 3 at different radial dimensions decrease from the inside to the outside along the radius of the rotor 3. That is to say, on the rotor 3, the radial dimensions of the pin 51 and the pin 52 are different. As Figure 4 shown, the radial dimension of the pin 51 from the center of the rotor 3 on the rotor 3 is smaller than that of the pin 52 from the center of the rotor 3 on the rotor 3. The pin 51 is located on the inner side close to the center of the rotor 3, and the pin 52 is located on the outer side far from the center of the rotor 3, so that the length of the pin 51 extending along the first direction is greater than the length of the pin 52 extending along the first direction. In other words, in the pin dispersion group 5, there are multiple pins 51 with relatively long lengths, and the pins 51 are arranged on the inner circle in the radial direction of the rotor 3, and there are multiple pins 52 with relatively short lengths, and the pins 52 are on the outer periphery in the radial direction of the rotor 3. In this embodiment, the pin dispersion group 5 is arranged such that the lengths of all pins follow a decreasing pattern from the inside to the outside along the radius of the rotor 3. Multiple pins 51 (or pins 52) of the same length are evenly distributed around the central axis of the rotor 3, and the lengths of the pins with different lengths gradually decrease from the inside to the outside along the radius of the rotor 3.

[0030] In this embodiment, the lengths of the pins (51, 52) are mainly set to adapt to the conical or frustum-shaped powder chamber 11. The length of the pin 51 closer to the central axis of the rotor 3 can extend as far as possible along the first direction into the powder chamber 11, while the length of the pin 52 located on the outer periphery of the rotor 3 is shorter to avoid interference with the inner wall of the housing 1.

[0031] As an example, in this embodiment, the pins (51, 52) can be cylindrical. The pins (51, 52) are connected to the rotor 3 in a detachable manner. For example, a thread is provided at one end of the pins (51, 52), and a threaded hole is provided on the rotor 3, and the rotor 3 and the pins (51, 52) are connected by means of the thread. The length direction (axial direction) of the pins (51, 52) is parallel to the axial direction of the rotor 3.

[0032] Notches are provided on the outer peripheral surfaces of the rod pins (51, 52). The notches are formed by cutting a part of the outer peripheral surfaces of the rod pins (51, 52). There are two notches, which are arranged oppositely. The two notches are used for wrench clamping. Without the notches, it is inconvenient for the wrench to clamp the rod pins (51, 52) and tighten the rod pins (51, 52) on the rotor 3.

[0033] In other embodiments, the rod pins (51, 52) can also be square rods.

[0034] In other embodiments, the rod pins (51, 52) are frustum-shaped. The bottoms of the rod pins (51, 52) are mounted on the rotor 3, and the tops of the rod pins (51, 52) have a smaller diameter than their bottoms.

[0035] In other embodiments, a plurality of protrusions can also be provided on the surfaces of the rod pins (51, 52). The protrusions can be fixed on the rod pins (51, 52) by welding or integrally molding. The protrusions can increase the contact surface between the rod pins (51, 52) and the object. Due to the presence of the protrusions, when the protrusions break up the caked material, they can act as sharp objects to split the material, thereby accelerating the crushing efficiency and crushing effect.

[0036] Specifically, as Figure 4 shown, the rod pins 51 (rod pins 52) at different radial dimensions on the rotor 3 in the rod pin dispersing group 5 are misaligned both radially and circumferentially on the end face of the rotor 3. That is to say, all the rod pins 51 are located at the same radial dimension on the rotor 3 and are evenly distributed along the circumferential direction, and all the rod pins 52 are located at the same radial dimension on the rotor 3 and are evenly distributed along the circumferential direction. At the same time, between the rod pins 51 and rod pins 52 of different radial dimensions, they are staggered with each other on the end face of the rotor 3, so that the rod pins 51 and rod pins 52 are not located on the same radius line. In this embodiment, the rod pins 51 with longer lengths and the rod pins 52 with shorter lengths are not on the same radius line of the common mounting surface. When pulverizing the powder material, if all the rod pins in the rod pin dispersing group 5 are arranged in a straight line according to the radius of the rotor (not shown in the figure), then a situation may occur: a plurality of rod pins are respectively arranged along two radii, and a part of the powder material will be accommodated in the fan-shaped space formed between the two radii of the rotor 3. These powder materials will rotate synchronously with the rod pins 51 (rod pins 52) on the two radii, and the powder materials in the fan-shaped space will not be broken. In this embodiment, as Figure 4 shown, the misaligned rod pins 51 (rod pins 52) do not form such a fan-shaped space, thereby reducing the probability of the powder material being clamped between two adjacent rod pins 51 (rod pins 52), and thus improving the crushing effect.

[0037] The number of the rod pins 51 (rod pins 52) contained on the rotor 3 at different radial dimensions in each of the rod pin dispersion groups 5 is different, and the number of the rod pins 51 (rod pins 52) gradually increases from the inside to the outside along the radial direction of the rotor 3. In this embodiment, as Figure 4 shown, there are a total of 2 rod pins 51 located at the same radial dimension, and there are a total of 4 rod pins 52 located at the same radial dimension. Along the radial direction of the rotor 3 from the inside to the outside, the number of the rod pins 51 (rod pins 52) gradually increases. If the number of the rod pins 51 (rod pins 52) contained in each rod pin dispersion group 5 is the same (not shown in the figure), then the interval between two adjacent rod pins 52 in the rod pin group closer to the outer edge of the rotor 3 is larger. Therefore, in order to reduce this phenomenon, the number of the rod pins 52 closer to the outer edge of the rotor 3 is greater than the number of the rod pins 51 closer to the center of the rotor 3.

[0038] For the convenience of understanding, in this embodiment, taking the rod pins 51 and rod pins 52 of two lengths as an example, the rod pin with a longer length is called the rod pin 51, and the rod pin with a shorter length is called the rod pin 52. One end face of the rotor 3 is the installation surface. The number of the rod pins 51 is a, and the a rod pins 51 are arranged around the center of the installation surface. The number of the rod pins 52 is b, b > a, and the b rod pins 52 are arranged around the center of the installation surface. The rod pins 52 are arranged on the outer ring of the installation surface, and the rod pins 51 are arranged on the inner ring of the installation surface. Although the rod pins 51 and rod pins 52 are on the same installation surface, the radius of the circle surrounded by the rod pins 51 is smaller than the radius of the circle surrounded by the rod pins 52.

[0039] In addition, the closer the rod pin 52 is to the outer ring, the larger the diameter of the circle it surrounds. Therefore, the number of the rod pins 52 closer to the outer ring of the installation surface can be more than the number of the rod pins 51 closer to the inner ring of the installation surface.

[0040] And the radius line of the rotor 3 where the rod pin 51 is located and the radius line of the rotor 3 where the rod pin 52 is located are not collinear, and the rod pins 51 and rod pins 52 are not collinear in the radial direction of the rotor 3.

[0041] In the first direction, a clearance is provided between the end of the rod pin 51 (rod pin 52) extending into the powder chamber 11 and the inner wall of the housing 1, and the clearance is 0.5 mm - 5 mm. This improves the smooth rotation of the rod pin dispersion group 5 in the housing 1. The clearance can be, but is not limited to, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm, etc.

[0042] In this embodiment, the housing 1 includes a cylinder 15 and an end cap 14 which are detachably connected. The end cap 14 is arranged at one end of the cylinder 15. The inner side of the end cap 14 has a cavity with a one-way opening, and the opening of this cavity faces the housing 1. The inner cavity of the cylinder 15 and the cavity of the end cap 14 together form the inner cavity of the housing 1. The inner cavity of the cylinder 15 and the end face of the rotor 3 away from the rod pin dispersion group 5 form a liquid material cavity 13. In this embodiment, a mixing cavity 12 is formed between the outer wall of the dispersion cylinder 32 and the inner wall of the housing 1. The powder and the liquid are mixed in the mixing cavity 12 to finally form a slurry.

[0043] A first mixing cavity 121 is formed by arranging the outer wall of the rotor 3 and the inner wall of the stator 4 at intervals. A second mixing cavity 122 is formed by arranging the stator 4 and the inner wall of the housing 1 at intervals. The first mixing cavity 121 and the second mixing cavity 122 together form the mixing cavity 12. A first through hole 35 is arranged on the rotor 3, and the first through hole 35 communicates the liquid material cavity 13 and the first mixing cavity 121. Second through holes and third through holes are arranged on the side wall of the stator 4. The second through holes and the third through holes are arranged at intervals along the axial direction of the stator 4. The second through hole communicates the first mixing cavity 121 and the second mixing cavity 122, and the third through hole communicates the second mixing cavity 122 and the powder material cavity 11. The powder material cavity 11 and the liquid material cavity 13 are arranged on both sides of the rotor 3 in the axial direction. The end face of the rotor 3, the inner wall of the stator 4, the end cap 14 and the housing 1 together form the powder material cavity 11.

[0044] Specifically, in this embodiment, the rotor 3 includes a fixed seat 31 fixedly connected to the rotating shaft 2, a dispersion cylinder 32 arranged on the side of the fixed seat 31 facing away from the powder crushing and dispersing mechanism, an extension plate 36 connected to one end of the dispersion cylinder 32 facing away from the fixed seat 31, and a guide strip 33. In the radial direction of the rotor 3, the dispersion cylinder 32 is arranged outside the fixed seat 31. A first through hole 35 is arranged on the dispersion cylinder 32, and the first through hole 35 communicates the inner cavity of the dispersion cylinder 32 and the first mixing cavity 121. The fixed seat 31 and the dispersion cylinder 32 are arranged at intervals in the radial direction of the rotor 3 to form a channel through which the liquid can flow. The extension plate 36 extends towards the inner wall side of the housing 1, that is, the extension plate 36 extends radially outward of the rotor 3. A first mixing cavity 121 is formed by arranging the outer wall of the dispersion cylinder 32 and the inner wall of the stator 4 at intervals.

[0045] In this embodiment, one end of the stator 4 extends radially outward to form a flange, and the stator 4 is connected to the end cap 14 through this flange. The other end of the stator 4 extends along its axis in the direction away from the end cap 14 until it is arranged at intervals from the extension plate 36. An annular groove is arranged on the extension plate 36 in this embodiment. One end of the stator 4 away from the end cap 14 is inserted into the groove, and the end face of the stator 4 is arranged at intervals from the bottom wall of the groove. Second through holes and third through holes are arranged in the middle of the stator 4. The second through hole communicates the first mixing cavity 121 and the second mixing cavity 122, and the third through hole communicates the powder material cavity 11 and the first mixing cavity 121.

[0046] The rotor 3 further includes a plurality of flow guiding bars 33 and shear bumps 34. The plurality of flow guiding bars 33 are arranged on the extension plate 36. The plurality of flow guiding bars 33 are evenly arranged around the axis of the rotor 3. Along the radial direction of the rotor 3, one end of the length direction of the flow guiding bar 33 is located inside the inner circle of the extension plate 36, and the other end of the length direction of the flow guiding bar 33 is located outside the outer circle of the extension plate 36. A plurality of first through holes 35 are provided. A flow guiding space for guiding the flow of liquid is formed between every two flow guiding bars 33. The inner end of the flow guiding bar 33 close to the central axis of the rotor 3 and the outer wall of the dispersion cylinder 32 are spaced apart. This space is for the stator 4 to be inserted. A gap is provided between the inner end of the flow guiding bar 33 close to the central axis of the rotor 3 and the outer wall of the stator 4. This gap is for shearing the liquid and powder to achieve the effect of dispersing the slurry.

[0047] The shear bumps 34 are arranged on the end face of the rotor 3 close to the powder chamber 11, that is, the shear bumps 34 are arranged on the surface of the fixed seat 31 close to the powder chamber 11. A plurality of shear bumps 34 are provided. The plurality of shear bumps 34 are evenly arranged around the central axis of the rotor 3. The shear bumps 34 are arranged on the outer edge of the fixed seat 31. The shear bumps 34 extend towards the inner wall of the stator 4. A gap is provided between one end of the shear bump 34 and the inner wall of the stator 4. This gap is also for shearing the liquid and powder to achieve the effect of dispersing the slurry.

[0048] The working principle of this embodiment is as follows:

[0049] The powder enters the powder chamber 11 from the powder inlet, and the liquid enters the liquid chamber 13 from the liquid inlet. The high-speed rotation of the rotor 3 drives the rod pin dispersion group 5 to rotate at a high speed. The rod pin dispersion group 5 extending into the powder chamber 11 breaks up the agglomerated powder.

[0050] The dispersed powder and liquid both enter the first mixing chamber 121, and after being sheared by the high-speed rotation of the stator 4 and the rotor 3, they enter the second mixing chamber 122 and are discharged from the discharge port 16 out of the housing. The liquid and powder are mixed in the first mixing chamber 121 and the second mixing chamber 122. During the mixing process, the high-speed rotating rotor 3 also drives the shear bumps 34 and the flow guiding bars 33 to rotate, so that the slurry mixed in the first mixing chamber 121 and the second mixing chamber 122 is sheared and dispersed multiple times by the cooperation of the shear bumps 34 and the inner wall of the stator 4, and is also sheared and dispersed multiple times by the cooperation of the flow guiding bars 33 and the outer wall of the stator 4, thereby improving the uniformity of the slurry.

[0051] At the same time, the mixed slurry can enter the housing 1 again through the liquid chamber 13 for circulating mixing. After repeating many times, the uniformity of the slurry is greatly improved.

[0052] In other embodiments, a plurality of rod pins 51 (rod pins 52) are provided in the rod pin dispersion group 5. The rod pins 51 (rod pins 52) are arranged around the center of the rotor 3, and the rod pins 51 (rod pins 52) in the rod pin dispersion group 5 are arranged at intervals from the inside to the outside along the radial direction of the rotor 3.

[0053] In other embodiments, eight rod pins 52 are provided, that is, b is 8. The eight rod pins 52 are divided into four groups. Two rod pins 52 are adjacent and arranged side by side. The eight rod pins 52 are evenly arranged in four groups, rather than directly evenly arranged with the center of the mounting surface as the center of the eight rod pins 52.

[0054] In other embodiments, three rod pins 51 can be provided. The three rod pins 51 are evenly arranged around the rotor, that is, the interval between two adjacent rod pins 51 is 120 degrees.

[0055] In other embodiments, along the axial direction of the rotor 3 and in the direction in which the powder chamber 11 gradually approaches the rotor 3, the cross-sectional area of the powder chamber 11 gradually increases. In this embodiment, it is not necessary to define the shape of the powder chamber 11 as a frustum or a cone, and it can also be an inner cavity with other special-shaped shapes that meet the above conditions.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
