Description

[0003] The tumbling plasticizing mixer is a device used to increase the plasticity of mixed materials after tumbling and crushing them.

[0004] In the prior art, the crushing and screening of materials are generally achieved through the coordinated design of a horizontal crushing wheel and a drum screen. The crushing wheel relies on continuous high-speed rotation to generate a large kinetic energy to achieve efficient crushing. This method requires a large driving force due to the need to maintain high-speed rotation, so the energy consumption is high. At the same time, the discharge method also relies on the inertia generated by the high speed of the crushed mixed material, which makes it difficult to control the discharge rate. In addition, the crushing effect for harder materials does not meet expectations, and the crushing efficiency is low. Moreover, due to the complex design of the crushing wheel and the drum screen, it is difficult to clean up the internal residues. Summary of the invention

[0032] The present invention has at least the following beneficial effects:

[0033] Traditional roller milling plasticizing mixers rely on high-speed rotation to achieve crushing, which requires a large driving force. In contrast, the present invention adopts a vertical rotating shaft design, and achieves roller milling crushing and screening through the cooperation of the roller milling crushing device and the cylindrical screen shell. Compared with relying only on the high-speed rotation of the rotating shaft, this design allows the roller milling rotating body to still work efficiently at a lower speed, thereby reducing energy loss and thus reducing energy consumption.

[0034] The present invention drives a plurality of roller grinding rotating bodies centered on the vertical rotating shaft to rotate along the inner wall of the cylindrical screen shell while the roller grinding rotating bodies can roll themselves. This dual motion mode can crush materials from multiple angles, thereby improving the crushing efficiency and crushing quality.

[0035] Moreover, the rolling of the roller mill rotor helps to disperse the force applied to the material, making it more evenly distributed in different parts of the material, reducing the risk of local over-crushing;

[0036] In addition, since the roller mill itself can also roll, the sliding friction between it and the inner wall of the cylindrical screen shell is reduced, thereby reducing wear and extending the service life of the equipment;

[0037] In addition, for materials of different hardness and particle size, the rolling of the rolling mill rotor can better adapt to the material characteristics. Because the combination of rolling mill and extrusion is adopted, the crushing effect of harder materials is better, and hard materials can be better processed and the crushing efficiency is improved.

[0038] At the same time, the rolling of the roller mill rotor helps to push the crushed material through the discharge holes on the cylindrical screen shell, thereby improving the screening efficiency and ensuring that fine particles can be screened out of the screen faster.

[0039] The design of the roller grinding and crushing device of the present invention simplifies the internal structure and reduces the possibility of material residue. At the same time, due to the large space design of the present invention, personnel can directly enter therein for maintenance, making cleaning work easier and more convenient than traditional designs.

[0040] The present invention controls the discharging of materials by rotating the discharging turntable. Specifically, the discharging rate can be adjusted according to actual needs by adjusting the transmission ratio, thereby improving the accuracy of discharging control.

[0050] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0051] Figures 1 to 7 A disc type roller mill plasticizing mixer is shown, comprising a base 1, in which a reducer 2 is installed; a vertical rotating shaft 21 is provided on the top of the base 1 and is drivingly connected to the output shaft of the reducer 2;

[0052] A mounting cylinder seat is fixedly installed above the base 1, and a vertical cylindrical screen shell 7 with a plurality of discharge holes 71 is fixedly installed above the mounting cylinder seat, and a rotatable rolling mill crushing device 9 is arranged inside the vertical cylindrical screen shell 7;

[0053] The vertical rotating shaft 21 passes through the mounting barrel seat along the central axis of the mounting barrel seat, and is in transmission connection with the rolling mill and crushing device 9, driving the rolling mill and crushing device 9 to rotate around the vertical rotating shaft 21;

[0054] The rolling mill crushing device 9 includes a rolling mill frame and two or more rolling mill rotating bodies 95;

[0055] The roller grinding frame includes an upper end plate 91, a lower end cover 92 and a plurality of connecting columns 93 for connecting and fixing the upper end plate 91 and the lower end cover 92. The mounting shafts 951 at the upper and lower ends of the roller grinding rotating body 95 are rotatably mounted on the upper end plate 91 and the lower end cover 92 respectively.

[0056] A central installation cylinder 921 is provided at the center between the upper end plate 91 and the lower end cover 92, the vertical rotating shaft 21 is fixedly installed in the central installation cylinder 921, and the rolling mill rotating bodies 95 are all installed between the upper end plate 91 and the lower end cover 92 with the central installation cylinder 921 as the center and in contact with the inner side wall of the vertical cylindrical screen housing 7;

[0057] The upper end plate 91 plays a role in dispersing the mixed material onto the inner side wall of the vertical cylindrical screen shell 7 when the rolling mill and crushing device 9 rotates as a whole, so as to cooperate with the rolling mill and crushing and discharging efficiency of the rolling mill rotating body 95 to prevent the mixed material from accumulating at the center of the vertical cylindrical screen shell 7. At the same time, it ensures that the mixed material is rolled and crushed smoothly, and the mixed material is smoothly discharged from the discharge hole 71 of the vertical cylindrical screen shell 7 after rolling and extrusion crushing;

[0058] A rotatable discharge turntable 5 is installed on the outer side wall of the mounting cylinder seat, and an inner vertical cylinder 51 located below the vertical cylindrical screen shell 7 is arranged on the upper side of the discharge turntable 5. An outer cylinder 4 fixedly installed on the base 1 is provided in a closed cooperation with the outer edge of the discharge turntable 5, and the outer cylinder 4 and the inner vertical cylinder 51 form a discharge ring groove, and the outer cylinder 4 is provided with a discharge port of the discharge ring groove, and the discharge port is provided with a guide plate 6 tangent to the outer wall of the inner vertical cylinder 51 along the discharge direction; the discharge turntable 5 rotates under the drive of the vertical rotating shaft 21, so that the crushed mixed material is discharged under the guidance of the discharge ring groove and the guide plate 6.

[0059] The mounting shaft 951 of the rolling mill rotating body 95 is sleeved with a limiting inner sleeve 9511 above the upper end plate 91, and a limiting outer sleeve 952 is sleeved on the outer side of the limiting inner sleeve. The limiting inner sleeve 9511 and the limiting outer sleeve 952 are limitedly engaged with each other. Specifically, the limiting inner sleeve 9511 can be a limiting block 953 or a limiting gear with a limiting protrusion, and the limiting outer sleeve 952 can be a limiting sleeve or a limiting gear sleeve with a limiting groove. In this embodiment, a limiting gear and a limiting gear sleeve are used because the limiting torque distribution of the two is better; the limiting outer sleeve 952 is fixed to the upper end plate 91 by a fixing component, and a protective cover (not shown in the figure) can also be provided here to cover the matching structures such as the limiting outer sleeve 952 and the limiting inner sleeve 9511 for protection; the rolling body 950 of each rolling mill rotating body 95 is provided with a plurality of rolling mill crushing teeth 9501 to enhance the rolling mill crushing effect.

[0060] Specifically, the fixing assembly includes a limit block 953 and a threaded fixing piece; the limit block 953 is fixedly arranged on the upper end plate 91, the limit sleeve 952 is limited by the limit block 953, and is fixed by setting a fixing hole 9521 in cooperation with the threaded fixing piece.

[0061] Each of the connecting columns 93 is provided with an adaptive auxiliary reinforcing rib 94 to assist in enhancing the load bearing capacity and impact resistance of the connecting column 93 in the up and down directions, so as to avoid the impact on the rolling mill crushing device 9 during unloading and thus affect the overall stable operation of the device;

[0062] One end of the auxiliary reinforcing rib 94 is hingedly mounted on the lower end cover 92 or the upper end plate 91 , and the other end contacts and cooperates with the upper end plate 91 or the lower end cover 92 , and is sleeved on one end of the corresponding connecting column 93 through a sleeve ring 941 .

[0063] Each discharge hole 71 is arranged in an inclined shape with the inner end higher than the outer end. Such arrangement is conducive to the mixed material after roller grinding and crushing to be discharged through the discharge hole 71, thereby improving the crushing and screening efficiency;

[0064] The specific fixing method of the guide plate 6 is as follows: the two ends of the guide plate 6 are respectively fixedly mounted on the mounting cylinder seat and the outer cylinder 4, and a small gap is provided between the bottom side of the guide plate 6 and the discharge turntable 5, so that the two can move relative to each other, and at the same time, the mixed material in the discharge ring groove is prevented from passing through the gap, but is discharged from the discharge port by the guiding effect of the guide plate 6;

[0065] The discharging turntable 5 is fixed on the base 1 by a plurality of mounting seat plates 3. The mounting seat plates 3 are all provided with vertical mounting plates 31 for fixing the outer wall of the outer tube 4. While playing a fixing role, they also act as reinforcement ribs of the outer tube 4, which is conducive to maintaining the outer tube 4 in a uniform cylindrical shape.

[0066] The central mounting cylinder 921 is integrally arranged with the lower end cover 92 , which is beneficial to the stable driving of the roller grinding and crushing device 9 ; the discharging turntable 5 is integrally arranged with the inner vertical cylinder 51 , which is beneficial to the stable operation of the discharging turntable 5 .

[0067] A guide limit groove may also be provided in the central mounting cylinder 921, and a guide block 211 adapted to the guide limit groove may be provided on the side of the vertical rotating shaft 21; the cooperation between the guide limit groove and the guide block 211 may play a role in guiding positioning and limiting relative rotation, which may greatly enhance the stability of the rotation drive and further reduce the adverse effects of the shear force on the vertical rotating shaft 21 and the central mounting cylinder 921.

[0068] Regarding balancing the driving of the vertical rotating shaft 21 on the roller grinding and crushing device 9 and reducing the space occupied, a more specific explanation is as follows: the central mounting cylinder 921 is a raised end sleeve integrally arranged on the lower end cover 92, and the vertical rotating shaft 21 is sleeved in the raised end sleeve and fixed on the top of the raised end sleeve by more than two bolts; such a setting can be used to reduce space occupied, and the space above the central mounting cylinder 921 expands the capacity of the vertical cylindrical screen shell 7, thereby improving the roller grinding and crushing processing efficiency.

[0069] Based on the above reasons, the central mounting cylinder 921 is not configured with its two ends fixedly connected to the upper end plate 91 and the lower end cover 92 respectively, but is configured as a raised end sleeve integrally provided with the lower end cover 92. However, the vertical rotating shaft 21 cannot be directly connected to the bottom side of the lower end cover 92. This is because in the present design, the vertical rotating shaft 21 not only drives the rolling mill and crushing device 9 to rotate, but also completes the rolling mill and crushing of the mixture through the rotation of the rolling mill and crushing device 9 in cooperation with the vertical cylindrical screen shell 7. Therefore, the vertical rotating shaft 21 and the rolling mill and crushing device 9 will be subjected to greater shear forces. The provision of raised end sleeves can well solve this problem, which not only meets the requirements of reducing space occupancy, but also overcomes the shear forces borne during the rolling mill and crushing process, thereby ensuring that the vertical rotating shaft 21 stably and reliably drives the rolling mill and crushing device 9 to complete the rolling mill and crushing of the mixture.

[0070] At the same time, since the force arm of the vertical rotating shaft 21 is relatively long, how to ensure the stable rotation of the rolling mill crushing device 9 during the rotation drive is also a problem that needs to be solved. In the present design, the rolling rotating body 95 contacts the inner wall of the cylindrical screen shell 7, and the vertical rotating shaft 21 is concentrically arranged with the cylindrical screen shell 7, so that the cylindrical screen shell 7 can provide guidance for the rolling mill crushing device 9 to achieve the balance of centrifugal force, thereby ensuring the smooth rotation of the vertically arranged rolling mill crushing device 9, and then realizing stable rolling crushing of the mixture.

[0071] In order to further achieve the smooth rotation of the roller mill crushing device 9, the present application also installs and fixes a guide limit ring 72 on the inner wall of the cylindrical screen housing 7 above the roller mill rotating body 95, which is used for guiding and limiting, so as to further ensure the smooth rotation of the roller mill crushing device 9. In order to prevent the fixing part from interfering with the roller mill rotating body 95, the guide limit ring 72 is fixedly installed by opening a countersunk hole 721 and cooperating with a countersunk thread fixing part.

[0072] The mounting cylinder seat is provided with an upper cover plate, which is beneficial to the installation of the cylindrical screen shell 7, the installation of the discharge turntable 5 and the seating of the lower end cover 92; the lower end cover 92 is rotatably seated on the upper cover plate, the cylindrical screen shell 7 is fixedly mounted on the upper cover plate, and the inner vertical cylinder 51 is arranged below the upper cover plate, which is beneficial to isolating the mixed material, thereby preventing the crushed mixed material in the discharge ring groove from affecting the vertical rotating shaft 21.

[0073] A hopper 8 is fixedly mounted on the top of the cylindrical screen housing 7 to facilitate the discharge of the mixed material;

[0074] A protective cover 922 is installed on the top of the raised end sleeve to protect the bolt connection and prevent the bolt connection from being loosened due to impact, thereby affecting the rotation driving effect of the roller grinding and crushing device 9 and further affecting the stable operation of the entire device;

[0075] The base 1 includes an upper shell 12 and a lower shell 11, and the mounting cylinder seat is fixedly mounted on the upper shell 12, so that it is easy to disassemble and install.

[0076] A driving sprocket 52 is provided on the bottom side of the discharging turntable 5, and a rotatable transmission shaft 54 ​​is installed on the upper shell 12, and a transmission gear 53 adapted to mesh with the driving sprocket 52 is installed on the transmission shaft 54. A first transmission wheel 55 is also installed on the transmission shaft 54, and a corresponding second transmission wheel 56 is installed on the vertical rotating shaft 21. The first transmission wheel 55 and the second transmission wheel 56 are connected by a belt or chain. The speed of the discharging turntable 5 can be adjusted by changing the transmission ratio between the first transmission wheel 55 and the second transmission wheel 56 and the transmission wheel and the driving sprocket 52, thereby controlling the discharging speed.

[0077] The first bearing and the second bearing are respectively installed between the vertical rotating shaft 21 and the mounting holes of the mounting cylinder seat and the base 1, and the third bearing and the fourth bearing are respectively installed between the discharge turntable 5 and the inner vertical cylinder 51 and the outer side wall of the mounting cylinder seat from the upper side and the lower side.

[0078] The lower end cover 92 is rotatably mounted on the mounting cylinder seat, and the lower end cover 92 and the vertical cylinder screen housing 7 are precisely matched, so that the lower end cover 92 can remain closed while rotating to prevent material leakage;

[0079] The working process is as follows: a plurality of rolling rotors 95 are arranged in a fixed vertical cylindrical screen shell 7, which can rotate around the central axis of the cylindrical screen shell 7 along with the center frame to achieve rolling and screening, and the fine mixed material after rolling and crushing is screened out along with the rotation of the center frame.

[0080] As the rotation speed of the center frame increases, the centrifugal force generated causes the remaining larger materials to move upward along the side wall of the vertical cylindrical shell screen, and then under the rolling and crushing action of the rolling rotating body 95, they are rolled and screened again, and this cycle repeats.

[0081] In short, after the mixed material is rolled and crushed by the rolling rotating body 95 of the rolling crushing device 9 in the cylindrical screen shell 7, it is squeezed and screened out from the discharge hole 71, and the crushed mixed material falls into the discharge ring groove. When the discharge turntable 5 is driven by the vertical rotating shaft 21 to rotate, the mixed material is transported to the discharge port along with the discharge turntable 5, and the discharge is achieved under the guidance of the guide plate 6.

[0082] This design has a large space, which allows personnel to enter directly and is easy to maintain; the material throughput is large and the processing efficiency is high. Because it uses a combination of tumbling and extrusion crushing and screening, it can better process hard materials.

[0083] In summary, the disc-type roller mill plasticizing mixer not only has improvements in energy saving, but also brings significant improvements in improving crushing efficiency, optimizing discharge control, simplifying maintenance work, etc.
