[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0024] like Figures 1 to 6 In the embodiment of the screening device for extracting kudzu root powder of the utility model shown in the figure, the screening device for extracting kudzu root powder comprises a screening assembly 1 and a housing 2, the screening assembly 1 comprises a truncated cone-shaped drum 13 and a cylindrical drum 14 fixedly arranged on the upper side of the truncated cone-shaped drum 13; the truncated cone-shaped drum 13 and the cylindrical drum 14 are arranged in two groups so as to fully screen the kudzu root slurry; the maximum diameter of the truncated cone-shaped drum 13 is equal to the diameter of the cylindrical drum 14 so that the two can be smoothly connected; a spray pipe 15 is fixedly arranged on the side wall of the truncated cone-shaped drum 13, and the distance between the spray pipe 15 and the conveying surface of the spiral blade 16 closest to it is equal to the distance between the spray pipe 15 and the conveying surface of the spiral blade 16 closest to it is equal to the distance between the spray pipe 15 and the conveying surface of the spiral blade 16 closest to it. etc., the spacing between adjacent spray pipes 15 is equal, so that the spray pipes 15 can smoothly mix the kudzu root slurry on the spiral blades 16; the side walls of the truncated cone drum 13 and the cylindrical drum 14 are fixedly provided with spiral blades 16 for conveying the kudzu root slurry from bottom to top, and the bottom end of the spiral blades 16 is provided with a feeding shovel 161 to smoothly shovel the material onto the spiral blades 16; the spiral blades 16 are in conflict with the inner wall of the shell 2; the shell 2 is provided with a filter hole 201 penetrating the side wall of the shell 2 at the side wall corresponding to the cylindrical drum 14, and a filter plate 21 is fixedly provided in the filter hole 201, and the filter plate 21 is made of hard material.

[0025] In the process of the spiral blades 16 transporting the kudzu root slurry from the truncated cone drum 13 to the cylindrical drum 14, the kudzu root slurry will be fully sprayed by the spray pipe 15. After fully absorbing water, the kudzu root slurry will be transported to the gap between the cylindrical drum 14 and the shell 2. At this time, the cylindrical drum 14, the spiral blades 16 and the filter plate 21 cooperate with each other, and the liquid in the kudzu root slurry is squeezed out through the filter plate 21 in the gap between the cylindrical drum 14 and the shell 2 to complete the screening process; the above process is repeated twice through two groups of truncated cone drums 13 and cylindrical drums 14, and the second process is consistent with the first process. The kudzu root residue screened for the first time will be fully sprayed by the spray pipe 15 again on the spiral blades 16 on the rotating shaft drum 14, and will be squeezed and screened again to fully complete the work of screening and extracting kudzu root powder; of course, the above process can also be repeated only once or more than twice.

[0026] In one embodiment of the present application, preferably, a drainage channel 3 is fixedly provided on the periphery of the filter hole 201, the bottom surface of the drainage channel 3 is inclined, and the bottom surface of the drainage channel 3 is fixed on a fixing ring 22 on the outer wall of the shell to smoothly collect the screened kudzu root powder liquid.

[0027] In one embodiment of the present application, preferably, a drainage pipe 26 parallel to the bottom surface of the inner cavity of the shell 2 is provided on the shell 2, and a filter plate 21 is also provided in the drainage pipe 26. If the water content in the kudzu root slurry is high, the water cannot be directly transported through the spiral blades 16, and therefore the drainage pipe 26 is required to remove the liquid on the bottom surface of the shell 2.

[0028] In one embodiment of the present application, preferably, a feed port 23 and a slag discharge port 24 are provided on the shell 2. The feed port 23 is located on the bottom surface of the inner cavity of the shell 2. The feed port 23 can be tilted to feed the material through a pipeline or a screw conveyor to ensure smooth feeding of the kudzu slurry; the slag discharge port 24 is located on the outer periphery of the side wall of the corresponding cylindrical drum 14 at the top of the shell 2, and the filtered kudzu slag will be driven by the spiral blades 16 to be discharged from the slag discharge port 24.

[0029] In one embodiment of the present application, preferably, a base 25 is provided on the shell 2 for rotationally connecting to the rotating shaft of the screening assembly 1, and a motor capable of driving the screening assembly 1 to rotate is provided in the base 25; a rotating shaft through hole 202 for passing the rotating shaft is provided at the top of the shell 2, and bearings are provided in the base 25 and the rotating shaft through hole 202; a pipeline capable of providing water for spraying to the spray pipe 15 is also provided in the base 25, and because the screening assembly 1 is in a rotating state, a rotatable pipe joint is required in the pipeline for spraying water.

[0030] In one embodiment of the present application, preferably, the pitch of the spiral blade 16 on the truncated cone drum 13 is smaller than the pitch on the cylindrical drum 14, because the channel of the kudzu root slurry is gradually narrowed during the process of being transported upward by the spiral blade 16, so setting different pitches can prevent the spiral blade 16 or other parts from being damaged due to excessive extrusion pressure.

[0031] In one embodiment of the present application, preferably, the screening assembly 1 includes a first screening assembly 11 and a second screening assembly 12, the first screening assembly 11 and the second screening assembly 12 are coaxially arranged, the second screening assembly 12 is arranged at the top of the first screening assembly 11, and the rotation speed of the first screening assembly 11 is greater than the rotation speed of the second screening assembly 12, which can be specifically achieved by a reducer, a reduction gear set or the second screening assembly 12 not giving up the power source (that is, the second screening assembly 12 does not rotate); there is a relative rotation speed between the first screening assembly 11 and the second screening assembly 12, so that the kudzu root slurry screened by the first screening assembly 11 can be smoothly scooped by the spiral blades 16 of the second screening assembly 12; the first screening assembly 11 and the second screening assembly 12 both include a truncated cone drum 13 and a cylindrical drum 14. The minimum diameter of the truncated cone drum 13 on the first screening component 11 is smaller than the minimum diameter of the truncated cone drum 13 on the second screening component 12. Since the first screening component 11 and the second screening component 12 have a relative rotation speed, and the volume of the kudzu root slurry after the first screening becomes smaller, the second screening component 12 does not need a smaller bottom diameter; the height of the cylindrical drum 14 on the first screening component 11 is smaller than the height of the cylindrical drum 14 on the second screening component 12, and the raised part is used for slag discharge. The top end surface of the cylindrical drum 14 on the first screening component 11 is provided with a bearing hole 1101 that is rotatably connected to the second rotating shaft of the second screening component 12, and the outer periphery of the bearing hole 1101 is provided with an isolation ring 111 that can be embedded in the second screening component 12, and the isolation ring 111 prevents liquid from entering the bearing hole 1101.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
