In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The utility model provides a material dewatering device, such as Figure 1 and Figure 2 As shown, the material dewatering device includes a dewatering unit and a self-adjusting unit. The dewatering unit includes a driving mechanism 1 and a material draining cylinder 2. The driving mechanism 1 is transmission-connected to the material draining cylinder 2 and can drive the material draining cylinder 2 to rotate around its own central axis. The material draining cylinder 2 is provided with a draining hole 21 connected to its own interior; the self-adjusting unit includes a moisture detector, which can monitor the moisture value of the material in the material draining cylinder 2, and the driving mechanism 1 can adjust the speed according to the moisture value monitored by the moisture detector.

[0035] like Figure 1 and Figure 2 As shown, when the moisture content of the material needs to be reduced, the material is transported to the material drainage barrel 2, and the control driving mechanism 1 drives the material drainage barrel 2 to rotate around its own central axis. The moisture in the material is drained out through the material drainage barrel 2 under the action of centrifugal force. In this process, the moisture detector monitors the moisture value of the material in the material drainage barrel 2, and adaptively and dynamically adjusts the rotation speed of the material drainage barrel 2 according to the target moisture value and the moisture value of the monitored material, so that the moisture value of the material can be quickly and efficiently stabilized near the target moisture value. It can be understood that when it is monitored that the moisture value of the material in the material drainage barrel 2 is large, the rotation speed of the material drainage barrel 2 can be controlled to increase to improve the drainage efficiency. When it is monitored that the moisture value of the material in the material drainage barrel 2 is small, the rotation speed of the material drainage barrel 2 can be controlled to decrease to ensure that the moisture value of the material obtained by drainage is more accurate. When it is monitored that the moisture value of the material in the material drainage barrel 2 reaches the target moisture value, the control driving mechanism 1 stops driving the material drainage barrel 2, and transfers the material in the material drainage barrel 2 to the next process. Compared with the existing technology, the moisture value of the material can be effectively controlled to be adjusted to the target moisture value during drainage, and the moisture value of the material can be adjusted to the target moisture value at one time, which effectively improves the processing efficiency and ensures the quality of the material.

[0036] Specifically, the self-regulating unit also includes a controller, which is electrically connected to the driving mechanism 1 and the moisture detector, and the controller can control the driving mechanism 1 according to the moisture value monitored by the moisture detector. Specifically, the moisture detector monitors the moisture value of the material in the material draining cylinder 2 and feeds it back to the controller, and the controller compares the target moisture value and the moisture value of the material obtained by monitoring, and dynamically adjusts the operation of the driving mechanism 1 according to the target moisture value and the moisture value of the material obtained by monitoring, and controls the rotation speed of the material draining cylinder 2 through the driving mechanism 1.

[0037] Specifically, for different types of materials, a table of material moisture values ​​and target rotation speeds of the material drain drum 2 can be obtained through a large number of experiments in the early stage. The target rotation speed of the corresponding material drain drum 2 is obtained from the table according to the moisture value of the material, and then the controller controls the driving mechanism 1 so that the rotation speed of the material drain drum 2 is adjusted to the target rotation speed.

[0038] In this embodiment, the exemplary material is stems. After the stems are drained, they are stored in a cabinet for about 3 to 72 hours. It can be understood that the material dewatering device can also be used to drain other types of materials.

[0039] Specifically, Figure 2As shown, there are multiple drain holes 21, and the multiple drain holes 21 are scattered and arranged along the circumference and axial direction of the material drain cylinder 2. To improve the drainage effect. In this embodiment, the exemplary arrangement of multiple drain holes 21 is a mesh distribution. It can be understood that the aperture of the drain hole 21 is set according to the actual type of material, and the material can be prevented from flowing out of the drain hole 21.

[0040] Preferably, if Figure 1 As shown, the driving mechanism 1 includes a fixed driving member 11 and a transmission assembly. The outer peripheral wall of the material draining barrel 2 is provided with a gear ring 12, and the output shaft of the driving member 11 and the gear ring 12 are connected by the transmission assembly. The driving member 11 is electrically connected to the controller. Such a configuration, compared with the prior art in which the driving shaft that drives the material draining barrel 2 to rotate around its own central axis is extended into the material draining barrel 2 and connected to the material draining barrel 2, can avoid direct contact between the driving shaft and the material to affect the quality of the material, the drainage effect and the service life of the driving shaft, and can maximize the volume of the material draining barrel 2, thereby further improving the processing efficiency and further ensuring the quality of the material.

[0041] Specifically, in this embodiment, Figure 1 As shown, the exemplary drive member 11 is a motor, and the transmission assembly is a gear transmission assembly, which includes a transmission gear 13, which meshes with the ring gear 12 and is connected to the output shaft of the motor. So that the material drain barrel 2 can be driven to rotate around its own central axis. It can be understood that the transmission assembly can also adaptively increase or decrease the number and specifications of gears according to actual working conditions, so as to adjust the rotation speed of the material drain barrel 2. In other embodiments, the transmission assembly can also be replaced by a turbine worm assembly, etc., which can achieve the effect of driving the material drain barrel 2 to rotate around its own central axis.

[0042] Preferably, if Figure 1 As shown, the material draining cylinder 2 is inclined relative to the horizontal plane, and the inlet end 22 of the material draining cylinder 2 is higher than the outlet end 23 of the material draining cylinder 2. With such arrangement, in the process of reducing the moisture content of the material, the material moves toward the outlet end 23 of the material draining cylinder 2 while draining under the action of centrifugal force, so that when it is monitored that the moisture value of the material in the material draining cylinder 2 reaches the target moisture value, most of the material can be concentrated at the outlet end 23 of the material draining cylinder 2, thereby facilitating the transfer of the material from the outlet end 23 of the material draining cylinder 2 to the next process.

[0043] Further preferably, in this embodiment, the moisture detector is arranged in the material drain cylinder 2 and distributed on one side of the material drain cylinder 2 close to the outlet end 23. The accuracy of the moisture value monitored by the moisture detector can be further improved.

[0044] Specifically, the angle between the central axis of the material draining cylinder 2 and the horizontal plane is in the range of 2° to 10°. It is understandable that the value of the angle between the central axis of the material draining cylinder 2 and the horizontal plane can be adaptively adjusted according to actual working conditions. For example, for stems, the angle between the central axis of the material draining cylinder 2 and the horizontal plane is preferably in the range of 2° to 3°.

[0045] Among them, Figure 1 , Figure 3 and Figure 4 As shown, the water removal unit also includes a fixed outer cylinder 3, which is sleeved on the material drain cylinder 2 and distributed on the outer periphery of the drain hole 21, and a drain port is provided at the bottom of the outer cylinder 3. By arranging the outer cylinder 3 on the material drain cylinder 2 and providing the outer cylinder 3 with a drain port, the water drained from the material drain cylinder 2 can be collected to avoid splashing of the water drained from the material drain cylinder 2, thereby further improving the performance of the material water removal device; secondly, the outer cylinder 3 is distributed on the outer periphery of the drain hole 21, and it can be understood that the inlet end 22 and the outlet end 23 of the material drain cylinder 2 extend out of the two ends of the outer cylinder 3 respectively, so as to facilitate the addition of materials into the material drain cylinder 2 through the inlet end 22, and also facilitate the transfer of materials in the material drain cylinder 2 from the outlet end 23 to the next process.

[0046] Preferably, if Figure 1 , Figure 3 and Figure 4 As shown, the central axis of the outer cylinder 3 is colinear with the central axis of the material drain cylinder 2. That is, the outer cylinder 3 is also inclined relative to the horizontal plane. The drain ports are distributed at the bottom of the outer cylinder 3, and along the axial direction of the outer cylinder 3, the drain ports are distributed on one side of the outer cylinder 3 close to the outlet end 23 of the material drain cylinder 2. It can be understood that the water drained from the material drain cylinder 2 flows along the inner circumferential wall of the outer cylinder 3 and gathers on one side of the outer cylinder 3 close to the outlet end 23 of the material drain cylinder 2, and finally flows out from the drain port. It can improve the drainage efficiency and drainage reliability.

[0047] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the outer wall of the outer cylinder 3 is also provided with a drain pipe 31, which is connected to the drain port for drainage.

[0048] Specifically, the water removal unit also includes two groups of seals, which are arranged one by one corresponding to the two ends of the outer cylinder 3 along the axial direction. The seals are used to seal the gap between the end of the outer cylinder 3 and the sleeve of the material drainage cylinder 2. Under the centrifugal force of the material drainage cylinder 2, the moisture in the material is thrown to the inner wall of the outer cylinder 3, and the moisture flows to the drain outlet along the inner wall of the outer cylinder 3 under the action of its own gravity. Therefore, the amount of moisture splashed to and / or flowing to the end of the outer cylinder 3 and the sleeve of the material drainage cylinder 2 is less. The use of seals is sufficient to seal the gap between the end of the outer cylinder 3 and the sleeve of the material drainage cylinder 2, thereby preventing moisture from flowing out from the gap between the end of the outer cylinder 3 and the sleeve of the material drainage cylinder 2, so as to further improve the performance of the material water removal device.

[0049] Exemplarily, in this embodiment, the preferred sealing member is felt. Felt is a flexible material, which can ensure that the material drain cylinder 2 can rotate well around its own central axis relative to the outer cylinder 3, and the felt is water-absorbent and can absorb moisture splashed to and / or flowing to the end of the outer cylinder 3 and the sleeve of the material drain cylinder 2. In other embodiments, the sealing member can also be set to a rubber sealing ring or the like. It can ensure that the material drain cylinder 2 can rotate well around its own central axis relative to the outer cylinder 3, and can prevent moisture from flowing out of the gap between the end of the outer cylinder 3 and the sleeve of the material drain cylinder 2.

[0050] The material dewatering device further includes a cleaning unit, which includes a flushing nozzle, which is arranged on the inner circumferential wall of the outer cylinder 3, and is used to spray water to flush the material drain cylinder 2 and the outer cylinder 3. After the material is drained, the flushing nozzle can be used to flush the material drain cylinder 2 and the outer cylinder 3, and the flushing nozzle can also be used to regularly flush the material drain cylinder 2 and the outer cylinder 3 to ensure the cleanliness of the material drain cylinder 2 and the outer cylinder 3, thereby avoiding secondary contamination of the material, and can further improve the processing efficiency and further ensure the quality of the material.

[0051] Specifically, the cleaning unit also includes a cleaning water source and a water pump distributed outside the outer cylinder 3, and the water pump can pump the water from the cleaning water source to the flushing nozzle. The water pump is electrically connected to the controller. It is configured in this way to supply water to the flushing nozzle, and the water supplied to the flushing nozzle can be pressurized to enhance the flushing effect of the flushing nozzle. Among them, structures such as a filter and / or a heater can be provided on the pipeline connecting the cleaning water source and the water pump, as well as on the pipeline connecting the water pump and the flushing nozzle. It can further enhance the cleaning effect and cleaning efficiency of the material drain cylinder 2 and the outer cylinder 3 cleaned by the cleaning unit.

[0052] Preferably, there are multiple flushing nozzles, and the multiple flushing nozzles are all arranged on the inner circumferential wall of the outer cylinder 3, and the flushing nozzles can be rotatably connected to the inner circumferential wall of the outer cylinder 3; or, the flushing nozzles are fixedly connected to the inner circumferential wall of the outer cylinder 3. It can further improve the cleaning effect and cleaning efficiency of cleaning the material drain cylinder 2 and the outer cylinder 3. Specifically, when the flushing nozzle is rotatably connected to the inner circumferential wall of the outer cylinder 3, the flushing nozzle can rotate under the action of pressurized water, so that it can not only flush the material drain cylinder 2, but also flush the outer cylinder 3. When the flushing nozzle is fixedly connected to the inner circumferential wall of the outer cylinder 3, the nozzles of part of the multiple flushing nozzles are directed toward the material drain cylinder 2, and the nozzles of the remaining part are directed toward the outer cylinder 3, so that the material drain cylinder 2 and the outer cylinder 3 can also be flushed. Among them, the connection method of the flushing nozzle rotatably connected to the inner circumferential wall of the outer cylinder 3 belongs to the prior art, which will not be repeated here. The connection method of the flushing nozzle fixedly connected to the inner circumferential wall of the outer cylinder 3 also belongs to the prior art, which will not be repeated here.

[0053] Further preferably, the drain pipe 31 is also connected to the input end of the purified water system, and the washing water source is also connected to the output end of the purified water system. The water discharged from the drain pipe 31 can be reused after being purified by filtering, settling, purifying and other processes, so as to improve the utilization rate of water. Among them, the specific structure of the purified water system belongs to the prior art and will not be repeated here.

[0054] Among them, Figure 1 and Figure 3 As shown, the water removal unit further includes a support assembly 4, which includes a fixed bearing seat 41 and a bearing 42, the inner ring of the bearing 42 is fixedly sleeved on the outer periphery of the material draining barrel 2, and the bearing seat 41 is fixedly sleeved on the outer ring of the bearing 42. Such an arrangement can further improve the smoothness of the rotation of the material draining barrel 2 around its own central axis.

[0055] Preferably, if Figure 1 and Figure 3 As shown, there are two support assemblies 4, and the two support assemblies 4 are spaced apart along the axial direction of the material drain cylinder 2. The two support assemblies 4 are respectively distributed near the inlet end 22 and the outlet end 23 of the material drain cylinder 2. The supporting performance of the material drain cylinder 2 can be improved, and the smoothness of the rotation of the material drain cylinder 2 around its own central axis can be further improved. In this embodiment, along the axial direction of the material drain cylinder 2, the driving mechanism 1 is exemplarily arranged near the inlet end 22 of the material drain cylinder 2, one of the support assemblies 4 is distributed between one end of the outer cylinder 3 and the driving mechanism 1, and the other is distributed between the other end of the outer cylinder 3 and the outlet end 23 of the material drain cylinder 2. It can be understood that the number of support assemblies 4 and the relative positions of the support assemblies 4 and the driving mechanism 1 can be adaptively adjusted according to the actual situation of the site.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
