[0034] As Figure 9As shown, the slurry stabilizing unit 70 includes a slurry stabilizing tank 71. A vertically arranged slurry stabilizing baffle 72 is provided at the bottom of the slurry stabilizing tank 71. A slurry stabilizing feed pipe is arranged in the slurry stabilizing tank 71 on one outer side of the slurry stabilizing baffle 72. The discharging section of the slurry stabilizing feed pipe extends vertically downward. A slurry stabilizing discharge port is provided at the bottom of the slurry stabilizing tank 71 on the other outer side of the slurry stabilizing baffle 72. The slurry stabilizing feed port is connected to the slurry discharging port 19 on the sizing tank 10. The height of the slurry stabilizing tank 71 is less than the height of the sizing tank 10 and greater than the height of the slurry distributing tank 21. A slurry stabilizing discharge pipe is provided at the slurry stabilizing discharge port and is connected to the bottom of the slurry distributing tank 21 through the slurry stabilizing discharge pipe. During specific operation, the slurry stabilizing tank 71 can be separately provided to achieve the transitional connection between the sizing tank 10 and the liquid distributing tank. Or the sizing tank 10 and the liquid distributing tank can be directly connected. Or both can be provided at the same time, that is, a slurry discharging pipe is provided at the slurry discharging port 19, and the slurry stabilizing feed pipe and the sizing slurry feed pipe 18 are connected to the slurry discharging pipe through a three-way joint. A regulating valve for regulating the connection state of each path is provided at the three-way joint, and different conveying paths are selected for use according to specific situations. Selecting the slurry stabilizing tank 71 can further buffer and mix the cotton slurry, and the concentration of the cotton slurry is more stable and reliable.

[0035] As Figure 6 , 7, as shown in Fig. 8, the fine material mechanism 40 includes a mounting housing which is composed of a trough-shaped mounting groove 41. The length direction of the mounting groove 41 is consistent with the bandwidth direction of the filter conveyor belt 31, and the length dimension of the mounting groove 41 matches the bandwidth dimension of the filter conveyor belt 31. The bottom of the mounting groove 41 is semicircular, the depth direction of the mounting groove 41 is arranged obliquely, and the height of the groove opening of the mounting groove 41 is greater than the height of the groove bottom. The groove opening of the mounting groove 41 is closer to the filter conveyor belt 31 than the groove bottom, and the groove opening of the mounting groove 41 corresponds to the discharge end of the filter conveyor belt 31 for receiving the unloaded wet cotton material. A rotatably assembled upper shaft body 42 and a lower shaft body 43 are installed in the mounting housing. The upper shaft body 42 is located above the lower shaft body 43. On the shaft body of the upper shaft body 42 located in the mounting housing, there are radially arranged dispersing spike teeth 44 for dispersing the wet cotton material. The shaft body of the lower shaft body 43 located in the mounting housing consists of a first shaft section and a second shaft section. Aggregating spike teeth 45 are arranged radially on both the first shaft section and the second shaft section. The dispersing spike teeth 44 are arranged in multiple columns at intervals along the circumferential direction of the upper shaft body 42. Each column of dispersing spike teeth 44 is arranged at intervals along the length direction of the upper shaft body 42, and the adjacent columns of dispersing spike teeth 44 are arranged at intervals and staggered along the length direction of the upper shaft body 42. Specifically, 4 columns of dispersing spike teeth 44 can be set. The aggregating spike teeth 45 are respectively arranged at intervals in a spiral shape on the first shaft section and the second shaft section, and the spiral directions (helical directions) are opposite. The overhanging end of the dispersing spike teeth 44 is set to a conical tip shape, and the overhanging end of the aggregating spike teeth 45 is set to a flat-shaped part, and the width of the flat-shaped part gradually increases along the A direction, where the A direction is the direction from the fixed end of the aggregating spike teeth 45 to the overhanging end. A discharge port for discharging the collected and dispersed wet cotton material is arranged in the middle of the bottom of the mounting groove 41, and the discharge port corresponds to the junction of the first shaft section and the second shaft section. Denote the aggregating spike teeth 45 arranged at the junction of the first shaft section and the second shaft section as M aggregating spike teeth 46. The aggregating spike teeth 45 on both outer sides of the M aggregating spike teeth 46 are respectively arranged at intervals on the first shaft section and the second shaft section according to two opposite spiral directions. The width direction of the flat-shaped part on the M aggregating spike teeth 46 is consistent with the length direction of the lower shaft body 43, and the width directions of the flat-shaped parts on the aggregating spike teeth 45 on both outer sides of the M aggregating spike teeth 46 are arranged in an intersecting shape (perpendicular shape) with the length direction of the lower shaft body 43. The flat-shaped part can be specifically formed by hammering or forging the overhanging end of the aggregating spike teeth 45. The flat shape here does not refer to a standard flat shape, but refers to a structure similar to a flat shape. The overhanging end of the dispersing spike teeth 44 is set to a conical tip shape, so as to reliably disperse the strip-shaped wet cotton material unloaded from the filter conveyor belt 31 and improve the dispersing effect. And the aggregating spike teeth 45 with a flat-shaped lower end can well guide the dispersed wet cotton material to the discharge port in the middle of the bottom of the mounting groove 41 and further disperse it, ensuring that the wet cotton material can be reliably concentrated and discharged, and improving the material transfer efficiency and reliability.Set the width direction of the flat part of the M aggregate tooth nail 46 in the middle to be consistent with the axial length direction of the lower shaft body 43, and the width direction of the flat parts of the other aggregate tooth nails 45 is perpendicular to the length direction of the lower shaft body 43, which is the key to ensuring stable collection and reliable unloading of wet cotton materials. The above arrangement can increase the contact surface between the aggregate tooth nail 45 and the wet cotton material and the aggregate tooth nail 45, ensure the effect of collecting and dispersing the wet cotton materials on both sides to the middle of the installation groove 41, and at the same time ensure that the wet cotton materials concentrated in the middle can be reliably unloaded, thereby improving the dispersing effect, the reliability of aggregation and feeding. Thus, it ensures the reliable dispersing treatment of wet materials and the requirement of transfer and conveying. During specific operation, the distance (axial length distance) between two adjacent aggregate tooth nails 45 along the length direction of the lower shaft body 43 can be set to be smaller than or approximately equal to the distance (axial length distance) between two adjacent dispersing tooth nails 44 along the length direction of the upper shaft body 42. In addition, a guiding plate 47 can be provided at the notch of the installation groove 41, and the wet cotton belt unloaded from the filtering conveyor belt 31 is guided into the installation groove 41 through the guiding plate 47.

[0036] The transfer mechanism 50 includes a transfer conveying pipe, and the transfer conveying pipe is respectively connected with a hot air device and a drying device. The hot air device is used to blow hot air into the transfer conveying pipe to pneumatically convey the wet cotton material into the drying device for drying treatment. The transfer conveying pipe has a feed pipe section 61, the feed pipe section 61 is arranged horizontally on the lower side of the installation groove 41, a feed port is provided on the feed pipe section 61, and the discharge port on the installation groove 41 and the feed port are connected through a feeding connecting pipe. A drum-shaped transfer housing 51 is provided on the feeding connecting pipe, and a transfer assembly is arranged in the transfer housing 51. The transfer assembly includes a transfer shaft 52 rotatably installed horizontally, the transfer shaft 52 is arranged parallel to the upper shaft body 42, and transfer plate members 53 arranged radially are provided on the transfer shaft 52. The transfer plate members 53 are arranged at intervals along the circumferential direction of the transfer shaft 52. During specific operation, 3 to 6 transfer plate members 53 can be set, and the transfer plate members 53 and the transfer housing 51 are in clearance fit or rotational sealing fit, so as to avoid the influence of the hot air flow in the lower transfer conveying pipeline on the normal dispersion and conveying of the wet cotton material in the fine material mechanism 40, and avoid the loss of the hot air flow, improve the reliability of wet cotton material conveying and reduce energy consumption. The drying device can specifically be an existing hot air drying device, such as a cyclone (air flow) dryer, and more specifically, a multi-stage drying method can be adopted for drying.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
