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 powder material chamber often has phenomena such as caking. After caking, it is difficult for the liquid to wet the inside of the massive powder when it enters the mixing chamber, thus affecting the finished product effect of the slurry.

[0009] Optionally, one end face of the shear rib plate away from the rotor includes a parallel plane and an inclined plane. The parallel plane is parallel to the end face of the rotor. The outer side of the parallel plane is connected to the inclined plane.

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 accompanying 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 machine, which includes a housing 1, a rotating shaft 2, a rotor 3, an impeller dispersion part 6 and a stator 5. The housing 1 is provided with an inner cavity, and the housing 1 is provided with a discharge port 16, a powder inlet and a liquid inlet. The stator 5 is fixed in the inner cavity of the housing 1. The rotor 3 is arranged inside the stator 5 in the radial direction. The rotating shaft 2 is connected to the rotor 3. The rotor 3, the rotating shaft 2 and the stator 5 are coaxially arranged. The inner cavity of the housing 1 includes a powder chamber 11 and a liquid material chamber 13. The powder chamber 11 is jointly enclosed by the inner wall of the stator 5, one end face of the rotor 3 along the first direction and the inner wall of the housing 1. The powder chamber 11 and the liquid material chamber 13 are arranged at opposite ends of the rotor 3. The powder inlet communicates with the outside and the powder chamber 11, and the liquid inlet communicates with the outside and the liquid material chamber 13. The impeller dispersion part 6 is arranged at one end of the rotor 3 along the first direction. The impeller dispersion part 6 can extend into the powder chamber 11 along the first direction. The first direction is parallel to the central axis of the stator 5. In this embodiment, the impeller dispersion part 6 is used to disperse the powder in the powder chamber 11. By inputting powder into the housing 1 through the powder inlet, after the powder enters the powder chamber 11, the high-speed rotating rotor 3 drives the impeller dispersion part 6 thereon to break the powder in the powder chamber 11, thereby reducing the phenomenon of powder accumulation and powder caking and granulation when entering the mixing chamber 12 in the prior art.

[0024] Specifically, the impeller dispersion part 6 in this embodiment includes a base and a plurality of shear rib plates 63 fixed on the base. The base is arranged at one end of the rotor 3 close to the powder chamber 11, and each shear rib plate 63 extends into the powder chamber 11 along the first direction. The powder chamber 11 is arranged at one end of the rotor 3 in the first direction, and the liquid material chamber 13 is arranged at one end of the rotor 3 in the opposite direction of the first direction.

[0025] In this embodiment, the base of the impeller dispersion part 6 and the rotor 3 are detachably connected by bolts. Specifically, the base of the impeller dispersion part 6 and the rotor 3 are synchronously rotated through bolt connection. During pulping, the rotor 3 rotates at a high speed, driving the impeller dispersion part 6 to rotate at a high speed, and the impeller dispersion part 6 disperses the powder in the powder chamber 11.

[0026] As an example, the powder chamber 11 is conical or frustum-shaped. The bottom end of the powder chamber 11 is arranged close to the rotor 3, and the top end of the powder chamber 11 is arranged away from the rotor 3, so that the cross-section of the powder chamber 11 gradually increases in the opposite direction of the first direction. The side of the shear rib plate 63 away from the rotor 3 extends into the powder chamber 11 from the bottom end of the powder chamber 11.

[0027] Specifically, one end of the stator 5 in the first direction in this embodiment is fixed on the housing 1. A part of the housing 1 extends into the inner cavity of the stator 5. The housing 1 extending into the stator 5 is arranged at an interval from the rotor 3. A conical or frustum-shaped cavity is arranged on the housing 1 extending into the inner cavity of the stator 5. The cavity on the housing 1, the end face of the rotor 3, and the inner wall of the stator 5 enclose a conical or frustum-shaped powder chamber 11. The powder chamber 11 in this embodiment is frustum-shaped. The central axis of the frustum-shaped powder chamber 11 is coaxial with the central axis of the rotor 3. The diameter of the frustum-shaped powder chamber 11 gradually increases from its top end to its bottom end. The powder inlet is communicated with the powder chamber 11. Since the powder chamber 11 is frustum-shaped, in the radial direction of the rotor 3 from inside to outside, the depth of the powder chamber 11 gradually decreases.

[0028] As an example, the surface of the side of the shear rib plate 63 away from the rotor 3 includes a parallel surface 631 and an inclined surface 632. The outer side of the parallel surface 631 is connected to the inclined surface 632. The parallel surface 631 is parallel to the end face of the rotor 3. Along the radial direction of the rotor 3 and from inside to outside, the inclined surface 632 gradually approaches the end face of the rotor 3. The inclined surface 632 gradually approaches from inside to outside on the end face of the rotor 3, so that the height by which the inclined surface 632 protrudes from the rotor 3 along the axial direction of the rotor 3 is less than the height by which the parallel surface 631 protrudes from the rotor 3 along the axial direction of the rotor 3, thereby being able to adapt to the frustum-shaped powder chamber 11. It is convenient to assemble the shear rib plate 63 into the powder chamber 11 and be able to rotate in the powder chamber 11, and the shear rib plate 63 adapted to the powder chamber 11 can extend towards the inclined surface of the powder chamber 11 to the greatest extent, thus ensuring the effect of pulverizing the powder.

[0029] Preferably, the inclined surface 632 is parallel to the inclined surface of the powder chamber 11.

[0030] In other embodiments, the shear rib plate 63 is slightly deformed (not shown in the figure). For example, the surface of the shear rib plate 63 away from the rotor 3 includes a first parallel surface, an inclined surface, and a second parallel surface that are sequentially connected in the radial direction of the rotor 3 from inside to outside. Both the first parallel surface and the second parallel surface are parallel to the end surface of the rotor 3. The height by which the first parallel surface protrudes from the end surface of the rotor 3 along the axial direction of the rotor 3 is greater than the height by which the second parallel surface protrudes from the end surface of the rotor 3 along the axial direction of the rotor 3. The two opposite sides of the inclined surface are respectively connected to the first parallel surface and the second parallel surface.

[0031] In this embodiment, in the first direction, there is a clearance interval between the side of the shear rib plate 63 extending into the powder chamber 11 and the inner wall of the housing 1, and the clearance interval is 0.5 mm - 5 mm. On the one hand, the smooth rotation of the impeller dispersing part 6 in the housing 1 is improved. The clearance interval 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.

[0032] As an example, in the radial direction of the rotor 3, the clearance interval gradually increases from inside to outside, so as to avoid the phenomenon of material accumulation and blockage at the powder inlet, and the larger the blanking space for the powder is closer to the mixing chamber 12, the powder can be discharged evenly, and thus the powder feeding efficiency is improved.

[0033] As an example, the base includes a bottom plate 61 and a boss 62. The boss 62 is fixed on the bottom plate 61. The bottom plate 61 is in the shape of a circular plate and is coaxial with the rotor 3. The boss 62 can rotate stably around its own first axis, and the first axis coincides with the central axis of the bottom plate 61. The boss 62 protrudes from one side plate surface of the bottom plate 61 in the first direction. The boss 62 and the shear rib plate 63 are arranged on the same side of the bottom plate 61. The cross-section of the boss 62 gradually decreases in the direction away from the bottom plate 61. One surface of the shear rib plate 63 along the radial direction of the bottom plate 61 extends in the direction towards the boss 62 and is fixed on the boss 62. One surface of the shear rib plate 63 in the opposite direction of the first direction is fixed on the bottom plate 61. A plurality of shear rib plates 63 are uniformly arranged around the central axis of the bottom plate 61. In this embodiment, the boss 62 is in the shape of a frustum of a cone and is coaxial with the rotor 3. A plurality of shear rib plates 63 are arranged around the boss 62.

[0034] 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 impeller dispersion group 6 form a liquid material chamber 13. In this embodiment, between the outer wall of the dispersion cylinder 34 and the inner wall of the housing 1 is a mixing chamber 12, where powder and liquid are mixed to finally form a slurry.

[0035] A first mixing chamber 121 is formed by arranging the outer wall of the rotor 3 and the inner wall of the stator 5 at intervals. A second mixing chamber 122 is formed by arranging the stator 5 and the inner wall of the housing 1 at intervals. The rotor 3 is provided with a first through hole 32, and the first through hole 32 communicates the liquid material chamber 13 and the first mixing chamber 121. On the side wall of the stator 5 are provided a second through hole 51 and a third through hole 52, and the second through hole 51 and the third through hole 52 are arranged at intervals along the axial direction of the stator 5. The second through hole 51 communicates the first mixing chamber 121 and the second mixing chamber 122, and the third through hole 52 communicates the second mixing chamber 122 and the powder chamber 11. The powder chamber 11 and the liquid material chamber 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 5, the end cap 14 and the housing 1 together form the powder chamber 11.

[0036] The impeller dispersion part 6 is fixed on the surface of the fixed seat 33 close to the powder chamber 11. Since the edge of the impeller dispersion part 6 is close to the junction of the powder chamber 11 and the mixing chamber 12, it can disperse the powder before the powder enters the mixing chamber 12, which can improve the quality of the powder entering the mixing chamber 12, thereby reducing the caking or accumulation of the powder at the junction of the powder chamber 11 and the mixing chamber 12. Moreover, since the volume of the powder entering the mixing chamber 12 is small, it is easily completely wetted by the liquid, thus improving the powder wetting and mixing effect and ensuring the uniformity of the slurry.

[0037] Specifically, in this embodiment, the rotor 3 includes a fixed seat 33 fixedly connected to the rotating shaft 2, a dispersion cylinder 34 arranged on the side of the fixed seat 33 facing away from the powder crushing and dispersing mechanism, an extension plate 35 connected to one end of the dispersion cylinder 34 facing away from the fixed seat 33, and a guide strip 36. In the radial direction of the rotor 3, the dispersion cylinder 34 is arranged outside the fixed seat 33. The dispersion cylinder 34 is provided with a first through hole 32, and the first through hole 32 communicates the inner cavity of the dispersion cylinder 34 and the first mixing chamber 121. The fixed seat 33 and the dispersion cylinder 34 are arranged at intervals in the radial direction of the rotor 3 to form a channel through which liquid can flow. The extension plate 35 extends towards the inner wall side of the housing 1, that is, the extension plate 35 extends radially outwards along the rotor 3. A first mixing chamber 121 is formed by arranging the outer wall of the dispersion cylinder 34 and the inner wall of the stator 5 at intervals.

[0038] In this embodiment, one end of the stator 5 extends radially outward to form a flange, which is connected to the end cover 14 through the flange. The other end of the stator 5 extends along its axis in a direction away from the end cover 14 until it is spaced apart from the extension plate 35. An annular groove is provided on the extension plate 35 in this embodiment. One end of the stator 5 away from the end cover 14 is inserted into the groove, and the end of the stator 5 is spaced apart from the bottom wall of the groove. A second through hole 51 and a third through hole 52 are provided in the middle of the stator 5. The second through hole 51 communicates with the first mixing chamber 121 and the second mixing chamber 122, and the third through hole 52 communicates with the powder chamber 11 and the first mixing chamber 121.

[0039] The rotor 3 further includes a guide strip 36 and a shear bump 31. A plurality of guide strips 36 are provided. The plurality of guide strips 36 are arranged on the extension plate 35. The plurality of guide strips 36 are evenly arranged around the axis of the rotor 3. Along the radial direction of the rotor 3, one end of the guide strip 36 in the length direction is located inside the inner circle of the extension plate 35, and the other end of the guide strip 36 in the length direction is located outside the outer circle of the extension plate 35. A plurality of first through holes 32 are provided. A flow guiding space for guiding the flow of liquid is formed between every two guide strips 36. The inner end of the guide strip 36 close to the central axis of the rotor 3 and the outer wall of the dispersion cylinder 34 are spaced apart. This space is for the insertion of the stator 5. A gap is provided between the inner end of the guide strip 36 close to the central axis of the rotor 3 and the outer wall of the stator 5. This gap is used to shear the liquid and powder to achieve the effect of dispersing the slurry.

[0040] The shear bumps 31 are provided on the end face of the rotor 3 close to the powder chamber 11, that is, the shear bumps 31 are provided on the surface of the fixed seat 33 close to the powder chamber 11. A plurality of shear bumps 31 are provided. The plurality of shear bumps 31 are evenly arranged around the central axis of the rotor 3. The shear bumps 31 are provided on the outer edge of the fixed seat 33. The shear bumps 31 extend towards the inner wall of the stator 5. A gap is provided between one end of the shear bump 31 and the inner wall of the stator 5. This gap is also used to shear the liquid and powder to achieve the effect of dispersing the slurry.

[0041] The working principle of this embodiment is as follows:

[0042] 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 impeller dispersing part 6 to rotate at a high speed. The impeller dispersing part 6 extending into the powder chamber 11 breaks up the agglomerated powder.

[0043] The broken powder and liquid both enter the first mixing chamber 121, and then enter the second mixing chamber 122 through the second through hole 51. The liquid and powder are mixed in the first mixing chamber 121 and the second mixing chamber 122, and finally discharged from the housing 1 through the discharge port 16. During the mixing process, the high-speed rotating rotor 3 also drives the shearing protrusion 31 and the guide bar 36 to rotate, so that the slurry mixed in the first mixing chamber 121 and the second mixing chamber 122 is sheared and broken up by the cooperation of the shearing protrusion 31 and the inner wall of the stator 5 for many times, and is also sheared and broken up by the cooperation of the guide bar 36 and the outer wall of the stator 5 for many times, thereby improving the uniformity of the slurry.

[0044] At the same time, the mixed slurry can enter the shell 1 again through the liquid material chamber 13 for cyclic mixing. After repeated mixing for many times, the uniformity of the slurry is greatly improved.

[0045] In other embodiments, the outer peripheral surface of the boss 62 is formed by an arc rotating 360 degrees around the central axis of the base plate 61, the end of the arc located at the top of the boss 62 is closer to the central axis of the base plate 61 than the end of the arc located at the bottom of the boss 62, and the cross-section of the boss 62 gradually decreases along the axis of the base plate 61.

[0046] In other embodiments, the boss 62 may also be a cylinder, a pyramid, a prism, a prism, etc. It is only necessary to ensure that when the boss 62 rotates at high speed with the rotor 3, there will be no radial jumping along the rotor 3 and lateral shaking along the rotor 3. In other words, the boss 62 can maintain dynamic balance during rotation.

[0047] In other embodiments, the shear rib 63 may also be arranged as follows: inclined from inside to outside along the radial direction of the rotor 3, that is, the side surface of the shear rib 63 away from the rotor 3 is inclined to gradually approach the rotor 3. In other words, the side of the shear rib 63 away from the rotor 3 is an inclined slope, and the inclination direction gradually approaches the end surface of the rotor 3 from inside to outside.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
