DETAILED DESCRIPTION
[0018] In order to better understand the purpose, structure and function of the present invention, the present invention is described clearly and completely below in conjunction with the accompanying drawings.
[0019] like Figure 1-Figure 3A papermaking crushing and refining machine shown in the figure comprises: a housing 1 and a plurality of support columns 2 arranged at the lower part of the housing 1. A feed port 3 is arranged at the top of the housing 1, and the feed port 3 is arranged in the middle of the housing 1 with a width at the top and a narrowness at the bottom, and the length of the feed port 3 is slightly smaller than the length of the housing 1; a crushing device, a filter screen 1 4, a collecting bin 5, a filter screen 2 6 and a grinding device are arranged in sequence from top to bottom inside the housing 1, wherein the feed port 3 corresponds to the crushing device, ensuring that all materials entering the feed port 3 enter the crushing device for crushing. The filter screen 14 is tilted downward, and there is a gap between its lower end and the inner wall of the housing 1, and the lower part of its bottom end is provided with the collecting drawer 5. The filter screen 14 screens the raw materials crushed by the crushing device, and the fragments of the same size fall into the grinding device below through the filter screen, and the larger fragments slide downward along the filter screen 14 and fall into the collecting drawer 5 through the gap. The larger fragments in the collecting drawer 5 are taken out from the collecting drawer 5 at regular intervals and put into the crushing again. In order to facilitate the removal of the collecting drawer 5, a handle 21 is provided on the side wall of the collecting drawer 5; a notch for inserting the collecting drawer 5 is provided on the side wall of the housing 1, and the notch is located below the lower end of the filter screen 14. The sieved fragments fall into the grinding mechanism through the filter screen 26, and the mesh diameter of the filter screen 26 is greater than or equal to the mesh diameter of the filter screen 14, so as to ensure that the sieved fragments can smoothly enter the grinding mechanism for grinding. The side wall of the housing 1 is also provided with a water inlet 8 to provide water for the grinding process; the bottom of the housing 1 is provided with a discharge port 7 for discharging the pulp water after grinding, and a valve is provided on the discharge port 7. In this embodiment, the pulverizing device is driven by a driving mechanism, and the driving mechanism is arranged on the side wall of the housing 1 .
[0020] In addition, the shell 1 includes an upper shell 9, a middle shell 10 and a lower shell 11 from top to bottom; the upper shell 9 is square, with a feed port 3 on the top, and the crushing device, the filter screen 1 4 and the filter screen 2 6 are arranged inside; the lower shell 11 is cylindrical, with the grinding device inside, and the water inlet 8 is arranged on the side wall. The shape of the upper shell 9 can ensure that the raw materials are completely ground by the crushing device to a greater extent, and compared with the circular shape, it can effectively prevent the raw materials from falling into the gap between the crushing device and the inner wall of the shell 1, resulting in incomplete crushing; the shape of the lower shell 11 can utilize the inner wall of the lower shell 11 for grinding, increase the grinding area, and improve the grinding efficiency.
[0021] like Figure 2 and Figure 3As shown, the pulverizing device includes two horizontally arranged rollers 12 rotatably connected to the upper shell 9, and the rollers 12 are connected to the driving mechanism; a plurality of cutters 13 are arranged along the axial direction of the rollers 12, and the cutters 13 on the two rollers 12 are arranged staggered along the axial direction without gaps, so as to ensure that all raw materials can be cut. The driving mechanism drives the rollers 12 to rotate relative to each other, that is, they both rotate toward the middle of the shell 1, and the cutters 13 are used to chop the raw materials. In a possible implementation, the driving mechanism includes two motors of the same model, the two motors are respectively connected to the two rollers 12, and the two motors rotate in opposite directions, driving the two rollers 12 to rotate relative to each other. In another possible implementation, the driving mechanism includes a gear 14 and a gear 2 15 which are coaxially connected to the two roller shafts 12, respectively, and a driving motor 16; the driving motor 16 is connected to the outer wall of the shell 1 through a motor seat, and its output shaft is connected to the gear 14, which is used to drive the gear 14 to rotate, and the gear 14 is meshed with the gear 2 15; the driving motor 16 can be directly connected to one of the roller shafts 12 through a coupling, or can be connected through a transmission belt to drive the roller shaft 12 and gear 14 to rotate.
[0022] Furthermore, the grinding device includes a grinding motor 17, a connecting shaft 18 and a grinding hammer 19; the grinding motor 17 is installed in the middle position of the upper part of the filter screen 6, and its output shaft is connected downward to the upper end of the connecting shaft 18, and the lower end of the connecting shaft 18 is connected to the grinding hammer 19; the grinding motor 17 drives the connecting shaft 18 and the grinding hammer 19 to rotate to grind the raw materials. In this device, a plurality of grinding heads are provided on the bottom and side walls of the grinding hammer 19, and the raw materials on the bottom and side walls of the shell 1 are all subjected to pulping. In order to prevent the raw materials from falling on the grinding motor 17 and being unable to be ground, a conical protective cover 20 is provided on the outer wall of the grinding motor 17, and the open end of the protective cover 20 is connected to the upper part of the filter screen 6; that is, the fragments falling on the protective cover 20 will slide along the outer wall of the protective cover 20 and fall onto the filter screen 6, and then fall into the lower shell 11. In order to facilitate the fragments on the grinding hammer 19 to fall to the bottom of the lower shell 11, the grinding hammer 19 is arc-shaped at the top and cylindrical at the bottom. The arc shape facilitates the fragments to fall, and the grinding hammer 19 can also be provided with a through groove running through from top to bottom.
