[0003] like Figure 1 As shown, the rotor device in the existing impurity removal pulping machine includes a main shaft 1', a fixed disk 2' and a hammer 3'. Several fixed disks 2' are evenly fixed on the main shaft 1'. Each fixed disk 2' is provided with several pin holes. Two adjacent fixed disks 2' are connected by a pin. The hammer 3' is mounted on the pin. The hammer 3' is spirally distributed along the axis of the main shaft. This results in that the outer edge of some fixed disks 2' is not covered by the hammer 3' and is exposed to the outside (such as Figure 2 As shown in the figure, during the working process, this part of the fixed disk 2' will contact with the garbage, which may easily cause the fixed disk 2' to wear, increasing the labor and production time cost of maintaining and replacing the fixed disk 2'. In addition, since the hammer heads 3' are distributed in a spiral shape, the positions of the pin holes between two adjacent fixed disks 2' are also distributed in a spiral shape, which requires a high processing accuracy of the pin hole positions during the processing of the fixed disk 2', otherwise it is easy to cause the pin holes of the two adjacent fixed disks 2' to be misaligned, and the hammer heads 3' cannot be further assembled.

[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] like Figure 3 to Figure 5 As shown, the impurity removal pulping machine rotor device provided in this embodiment includes a main shaft 1, a plurality of mounting plates 2 and a plurality of hammer heads 3.

[0049] The mounting plate 2 is fixedly connected to the outer peripheral surface of the spindle 1 and extends in a direction away from the central axis of the spindle 1. A plurality of mounting plates 2 are distributed on the spindle 1 in a spiral shape along the axial direction of the spindle 1. A plurality of hammer heads 3 correspond to a plurality of mounting plates 2 one by one. The hammer heads 3 are arranged at one end of the mounting plate 2 away from the spindle 1. The hammer heads 3 include a mutually connected working portion 31 and two connecting portions 32. The two connecting portions 32 are connected to the end of the mounting plate 2 away from the spindle 1. The end of the mounting plate 2 away from the spindle 1 is located between the two connecting portions 32. The working portion 31 extends in a direction away from the central axis of the spindle 1. That is, the working portion 31 is located at the outermost periphery away from the spindle 1, and the end of the mounting plate 2 away from the spindle 1 is sandwiched by the two connecting portions 32.

[0050] During specific implementation, the impurity removal pulping machine rotor device rotates at a high speed inside the working chamber, and the garbage to be processed rotates together with the impurity removal pulping machine rotor device in the working chamber. Under the action of centrifugal force, the garbage moves away from the rotation center and clings to the inner wall of the working chamber. Since the working part 31 is located at the outermost periphery away from the main shaft 1, the component that mainly contacts the garbage is the working part 31 of the hammer head 3. In addition, since the end of the mounting plate 2 away from the main shaft 1 is sandwiched by the two connecting parts 32, the contact between the mounting plate 2 and the garbage can be reduced or avoided.

[0051] The impurity removal pulping machine rotor device provided in the present embodiment realizes the installation of the hammer head 3 by setting up a plurality of independent mounting plates 2, and the working part 31 of the hammer head 3 is set at the outermost periphery away from the main shaft 1, and the two connecting parts 32 of the hammer head 3 clamp the end of the mounting plate 2 away from the main shaft 1, so that the direct contact between the mounting plate 2 and the garbage can be reduced or avoided, so that the mounting plate 2 is not easy to wear, thereby reducing the frequency and cost of maintenance and replacement of the mounting plate 2; in addition, each hammer head 3 is individually installed on a mounting plate 2 in a one-to-one correspondence, so there is no mutual assembly connection relationship between the mounting plates 2, which is conducive to reducing the processing accuracy requirements and assembly difficulty.

[0052] like Figure 4 As shown, in some embodiments, the outer surface of the mounting plate 2 is provided with a wear-resistant protective plate 4 , which is detachably connected to the mounting plate 2 and covers the outer surface of the mounting plate 2 .

[0053] In the special case where the amount of waste to be processed increases dramatically, the rotation resistance of the hammer head 3 increases, and the hammer head 3 may tilt and fall. At this time, the waste in the working chamber will approach the axis of the main shaft 1, causing the mounting plate 2 to contact the waste. Therefore, the wear-resistant guard plate 4 provided on the outer surface of the mounting plate 2 can protect the mounting plate 2 and prevent the mounting plate 2 from being worn. Even if the wear of the wear-resistant guard plate 4 is serious after long-term use, it can be removed from the mounting plate 2 and easily replaced.

[0054] Optionally, the wear-resistant guard plate 4 is connected to the outer surface of the mounting plate 2 by screws. In this way, the installation and disassembly of the wear-resistant guard plate 4 is simple, and the screws can still maintain good connection performance during multiple assembly and disassembly processes and can be reused.

[0055] like Figure 4 As shown, in some embodiments, the wear-resistant guard plate 4 is provided in parts.

[0056] For example, the mounting plate 2 in this embodiment includes a square body part and a semicircular body part, and the wear-resistant guard plate 4 is arranged in a split body, that is, the wear-resistant guard plate 4 includes several pieces, such as four wear-resistant guard plates 4 respectively connected to the four exposed surfaces of the square body part, and one wear-resistant guard plate 4 connected to the arc surface of the semicircular body part. Through such an arrangement, when a certain wear-resistant guard plate 4 needs to be replaced after being worn, only the wear-resistant guard plate 4 needs to be disassembled and replaced, and the remaining wear-resistant guard plates 4 and the hammer head 3 connected to the mounting plate 2 are not affected.

[0057] like Figure 3 and Figure 5 As shown, in some embodiments, multiple mounting plates 2 are arranged on the outer peripheral surface of the main shaft 1 in the shape of multiple spiral lines to improve the dispersion and crushing effect of garbage. For example, they are distributed in two spiral lines, or three spiral lines, which are not specifically limited here. In addition, the spiral line can be left-handed or right-handed, which is not specifically limited here.

[0058] Alternatively, if Figure 4 As shown, the two connection parts 32 are connected to the mounting plate 2 through the pin shaft 7, and the pin shaft 7 passes through the two connection parts 32 and the mounting plate 2. In this way, the connection method through the pin shaft 7 is simple and fast, and the pin shaft 7 can allow the hammer head 3 to have a certain rotation and adjustment space, thereby reducing the damage to the hammer head 3 and the mounting plate 2 caused by the impact force generated by the material processed during the working process.

[0059] Alternatively, if Figure 4 As shown, the working part 31 is in the form of a sheet. That is, the hammer head 3 is in the form of a hammer sheet, which has a simple shape and is easy to process and manufacture.

[0060] Furthermore, if Figure 4 As shown, the working portion 31 has a working surface 311, which is the largest surface on the working portion 31, and the working surface 311 is arranged at an angle relative to the central axis of the spindle 1. That is, the working surface 311 is not parallel or coplanar with the central axis of the spindle 1, and there is a certain angle between the two, and the angle of the angle is not specifically limited here.

[0061] With such an arrangement, the working surface 311 of the working part 31 is arranged at an angle relative to the central axis of the main shaft 1, so that a shearing effect can be generated when the hammer head 3 contacts the material, which helps to cut and crush the material more effectively. In addition, the inclination angle of the working surface 311 can also make the material easier to discharge and reduce blockage.

[0062] In other embodiments, the working part 31 may also be hammer-shaped. The hammer-shaped working part 31 can quickly and effectively crush materials with higher hardness.

[0063] like Figure 3As shown, in some embodiments, the outer circumference of the main shaft 1 is sleeved with a sleeve 5, and the mounting plate 2 is fixedly connected to the outer circumference of the sleeve 5. By providing the sleeve 5, the mounting plate 2 can be connected to the sleeve 5, so that direct grooving on the main shaft 1 is avoided, which is conducive to improving the structural strength of the main shaft 1 itself.

[0064] like Figure 3 and Figure 5 As shown, in some embodiments, the sleeve 5 has a plurality of independent segments 51, which are sequentially sleeved on the outer peripheral surface of the main shaft 1 along the axial direction of the main shaft 1, and the main shaft 1 is provided with a shoulder 11, and one end of the sleeve 5 along the axial direction of the main shaft 1 abuts against the shoulder 11. The main shaft 1 is also sleeved with a locking nut 6, which is provided at one end of the sleeve 5 away from the shoulder 11 along the axial direction of the main shaft 1, and the locking nut 6 is configured to apply an axial pressing force to the segments 51 on the sleeve 5 away from the shoulder 11. That is, the plurality of segments 51 are located between the locking nut 6 and the shoulder 11, and the plurality of segments 51 are clamped and locked by the cooperation of the locking nut 6 and the shoulder 11.

[0065] By setting the shaft sleeve 5 to have a structure with multiple segments 51, compared with the shaft sleeve 5 being an integral form, it is more convenient to process the groove or hole for positioning and installing the mounting plate 2 on a single segment 51, the processing amount of one-time processing is small, and the processing cost is low. In addition, the multiple segments 51 are pressed and fixed by the cooperation of the locking nut 6 and the shaft shoulder 11, and this method will not cause damage to the main shaft 1. If other methods are used to fix each segment 51, such as welding the segment 51 to the main shaft 1, it is easy to cause deformation of the main shaft 1.

[0066] Specifically, the number of the multiple segments 51 may be determined according to actual conditions. Figure 3 and Figure 5 As shown, in the present embodiment, three spiral lines are distributed on the main shaft 1, and for each spiral line, a mounting plate 2 is fixed on a segment 51. In other embodiments, for each spiral line, multiple mounting plates 2 can be fixed on a segment 51. At this time, when the total length of the sleeve 5 and the number of mounting plates 2 are constant, the number of segments 51 is reduced accordingly.

[0067] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
