DETAILED DESCRIPTION

[0017] 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.

[0018] like Figures 1 to 4In one embodiment of the kudzu root powder sedimentation centrifugal device of the utility model, the device comprises a sedimentation tank 1, a slurry centrifugal drum 2, a pumping device 4 for pumping the slurry from the sedimentation tank 1 to the slurry centrifugal drum 2, a pumping pipe disposed near the bottom plate of the sedimentation tank 1 is disposed on the pumping device 4, and at least two filter devices 3 are disposed at intervals in the sedimentation tank 1; the filter device 3 comprises two filter racks 31 disposed at intervals and both hinged on the side wall of the sedimentation tank 1, a driving device 32 for driving the two filter racks 31 to swing at the same time, and a blocking filter plate 39 fixed on the side wall of the sedimentation tank 1; the blocking filter plate 39 is vertically disposed between the filter rack 31 and the pumping pipe; the planes where the two adjacent filter racks 31 are located are always intersecting. By designing two filter racks disposed at intervals and two synchronously swinging filter racks whose planes are not parallel, the slurry is fully filtered, and the filter plate can be swung through the slurry to flush the filter plate, thereby reducing the risk of the fiber in the slurry blocking the filter hole and affecting the service life of the filter plate, and the deposited slurry is driven to be quickly transmitted toward the direction close to the slurry centrifugal drum, thereby ensuring the full collection of the slurry and improving the utilization rate of the slurry.

[0019] Specifically, the driving device 32 includes an electric actuator 33 that drives a filter frame 31 to swing back and forth around its hinge axis, and a connecting rod device 34 that drives the adjacent filter frame 31 to swing simultaneously; the top ends of both sides of the filter frame 31 are provided with guide rods 35 that protrude outward; the connecting rod device 34 includes two bent rods 36 whose bent ends are respectively hinged on the opposite side walls of the sedimentation tank 1; the bent rod 36 includes a first connecting rod 361 connected to one filter frame 31 and a second connecting rod 362 connected to another filter frame 31; the first connecting rod 361 is provided with a first slideway 37 for the guide rod 35 to pass through; the second connecting rod 362 is provided with a second slideway 38 for the guide rod 35 of another filter frame 31 to pass through. Through the connecting rod device connecting the two filter plates, the two filter plates are driven to swing simultaneously and in opposite directions, so that the filter plates are flushed and the filtered slurry is alternately blocked at the same time, so as to fully filter the slurry.

[0020] Specifically, a stopper 11 for blocking and positioning the filter frame 31 is provided inside the side wall of the sedimentation tank 1 .

[0021] Specifically, the bottom plate of the sedimentation tank 1 is tilted downwardly in the direction close to the slurry centrifuge cylinder 2 .

[0022] Specifically, the filter frame 31 includes a detachable filter plate 311 and a first insertion channel 312 for inserting and installing the filter plate 311 ; a first handle hole 313 is provided on the top of the filter plate 311 .

[0023] Specifically, the blocking filter plate 39 includes a detachable second filter plate 391 and a second insertion channel 392 for the second filter plate 391 to be inserted and installed; a second handle hole 393 is provided on the top of the second filter plate 391 .

[0024] The slurry centrifuge cylinder 2 is a centrifugal device in existing design, which can adopt the centrifugal filter cylinder disclosed in the background art CN219111077U, or other common liquid centrifuges in existing design.

[0025] Working principle: The staff guides the slurry to the sedimentation tank 1. After being filtered and blocked by multiple filter plates 311, the slurry gathers and settles at the bottom of the sedimentation tank 1 and flows along the inclined bottom plate toward the slurry centrifuge cylinder 2. After being filtered by multiple filter plates 311 and finally filtered by the blocking filter plate 39, it is pumped into the slurry centrifuge cylinder 2 through the pumping pipe for centrifugation. After a period of use, the electric actuator 33 is started to drive the filter frame 31 to reciprocate. The filter frame 31 swings around its hinge axis away from the block 11 and drives another adjacent filter frame through the connecting rod device 34. 31 performs reverse swing. When one filter frame 31 is placed on a vertical plane, the other filter frame 31 linked with it by the connecting rod device 34 is at the position with the maximum swing inclination angle. The filter frame 31 swings to the highest position and then drops and swings to the vertical position for one round trip. During the swinging process, the slurry flushes the filter holes of the filter plate 311, cleans the filter holes blocked during filtration, and ensures the use effect of the filter plate 311. When the filter frame 31 swings from the highest point of the swing to the vertical position, it pushes the sedimentation liquid deposited near it to start pushing in the direction close to the slurry centrifuge cylinder 2, thereby improving the movement efficiency of the deposited slurry and ensuring that the slurry is fully transmitted.

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.
