[0032] As described in the background, in the extraction process of the components of traditional Chinese medicine, there are solid impurities in the liquid of traditional Chinese medicine, such as original plant tissues, so it has an impact on the purity of traditional Chinese medicine extraction. In the existing scheme, a simple standing filtration method is usually used to complete the filtration and purification of traditional Chinese medicine liquid, and this method affects the purification efficiency. In order to better solve this problem, the researchers in the present application put forward a kind of filtering device, in the filtering device, first, the traditional Chinese medicine liquid is centrifuged and filtered, and then the traditional Chinese medicine liquid obtained after centrifugal filtration is filtered again by extrusion filtration. The researchers plan to improve the filtration efficiency of traditional Chinese medicine liquid by this way, and also ensure the purity of traditional Chinese medicine liquid after extraction.

[0033] Referring to Figure 1 , Figure 1The utility model discloses an embodiment of the utility model provides a filter device, which comprises a box body 100, a first filter unit 200 and a second filter unit 300. The box body 100 is used for accommodating the first filter unit 200 and the second filter unit 300, and collecting the traditional Chinese medicine liquid filtered by the second filter unit 300. The first filter unit 200 is used for centrifugal filtration of the filter unit. The traditional Chinese medicine liquid flowing out of the first filter unit 200 enters the second filter unit 300, and the traditional Chinese medicine liquid is squeezed and filtered in the second filter unit 300.

[0034] Specifically, the filter device comprises a first filter unit 200 arranged in the box body 100. The first filter unit 200 comprises a centrifugal module 210. The traditional Chinese medicine liquid enters the centrifugal module 210 and is separated by the centrifugal module 210. The second filter unit 300 is in communication with the first filter unit 200. The second filter unit 300 is used for receiving the traditional Chinese medicine liquid separated by the centrifugal module 210. The second filter unit 300 comprises a filter layer 320 and a squeezing module 310. The squeezing module 310 is used for applying a force to the traditional Chinese medicine liquid so that the traditional Chinese medicine liquid is filtered again in the filter layer 320.

[0035] In the embodiment, when the traditional Chinese medicine liquid needs to be filtered, the traditional Chinese medicine liquid is delivered to the first filter unit 200. The traditional Chinese medicine liquid is subjected to the first solid-liquid separation in the centrifugal module 210 of the first filter unit 200, so that the solid impurities, such as tissue parts, in the traditional Chinese medicine liquid are removed. It should be noted that under the centrifugal action of the centrifugal module 210, the liquid part is separated and delivered to the second filter unit 300. In the second filter unit 300, the liquid part is subjected to the second separation from the filter layer 320 under the squeezing action of the squeezing module 310, so that the fine impurity part in the traditional Chinese medicine liquid is removed again. Through the separation of the traditional Chinese medicine liquid by the centrifugal module 210 in the first filter unit 200 and the secondary filtration of the traditional Chinese medicine liquid by the squeezing module 310 and the filter layer 320 in the second filter unit 300, the efficiency of filtering the traditional Chinese medicine liquid is improved, and the purity of the filtered traditional Chinese medicine liquid is improved. It should be noted that the size of the plant tissue during the filtration in the centrifugal filter module is greater than the size of the plant tissue during the filtration in the filter layer 320.

[0036] In an embodiment, referring to Figure 2 The centrifugal module 210 comprises a barrel 211 and a first driving element 212. The sidewall of the barrel 211 is provided with a through hole 213. The through hole 213 is located in the middle of the barrel 211 and is deviated upward. The first driving element 212 drives the barrel 211 to rotate when rotating. The first driving element 212 can be a servo motor.

[0037] In the embodiment, the output end of the first driving element 212 can drive the rotation of the barrel 211, and the centrifugal force is generated during the rotation of the barrel 211. The Chinese medicine liquid can rotate upward from the bottom of the barrel 211 and flow out along the through hole 213 during the rotation of the barrel 211. Specifically, since the density of the impurities such as plant tissues is generally larger than that of the liquid, the impurities are more significantly affected by the centrifugal force, and thus the centrifugal force pushes the impurities to the outer wall of the barrel 211. When the impurities reach the outer wall of the barrel 211, the gravity starts to play a major role, and the impurities are accumulated at the bottom of the barrel 211. The liquid is also affected by the centrifugal force during the rotation of the barrel 211. However, the density of the liquid is relatively small, and thus the centrifugal force has a relatively weak effect on the liquid. The centrifugal force makes the liquid move outward as a whole. Since the barrel 211 rotates and the through hole 213 exists, the liquid is not only affected by the radial centrifugal force, but also affected by the axial pressure gradient. Specifically, the liquid flows outward in the radial direction, and at the same time, the liquid is pushed upward in the axial direction, and finally flows out through the through hole 213. The reason is that the position of the through hole 213 is in the middle upper part, and thus the pressure of the liquid near the through hole 213 is relatively low. The pressure difference promotes the liquid to flow from the area with high pressure to the area with low pressure, that is, to move from the bottom of the barrel 211 to the through hole 213. In the embodiment, the output end of the first driving element 212 can be connected to the bottom of the barrel 211, so as to drive the rotation of the barrel 211 through the rotation of the first driving element 212.

[0038] Further, in an embodiment, the through hole 213 is annularly distributed on the side of the barrel 211; and / or, the through hole 213 is provided with a detachable filter screen.

[0039] In the embodiment, the through hole 213 is annularly distributed on the side of the barrel 211, because the annular design can ensure that the discharge paths of the Chinese medicine liquid after centrifugal separation from all directions are balanced, which helps to reduce the phenomenon that the Chinese medicine liquid flows irregularly or accumulates on one side of the barrel 211. In addition, the detachable filter screen arranged at the through hole 213 can reduce the blockage of plant tissues and the like in the Chinese medicine liquid at the through hole 213.

[0040] In an embodiment, referring to Figure 2 The inner wall of the barrel 211 is further provided with a flow guide structure 214 extending upward along the bottom of the inner wall of the barrel 211. The width of the flow guide structure 214 gradually decreases from the bottom of the barrel 211 to the upper part of the barrel 211. The flow guide structure 214 is close to the through hole 213, and the flow guide structure 214 guides the Chinese medicine liquid to enter the through hole 213.

[0041] In the embodiment, firstly, under the action of centrifugal force, the liquid is pushed to the outer wall of the barrel 211, and meanwhile, under the guidance of the spiral flow guide structure 214, the liquid can gradually move upward along the spiral path, effectively avoiding the radial rotation or local retention of the liquid on the inner wall of the barrel 211. Through the arrangement of the flow guide structure 214, the liquid is guided to the position close to the through hole 213 after being subjected to the sufficient action of the centrifugal force, thereby realizing the uniform flow of the liquid and the effective separation from the impurities, and finally improving the discharge efficiency and separation effect of the liquid.

[0042] In addition, the width of the flow guide structure 214 is wider at the bottom, which can provide a larger contact surface to guide the initial flow of the liquid. As the liquid gradually rises, the width of the flow guide structure 214 gradually decreases, which can reduce the resistance of the liquid flow and avoid the stagnation or backflow phenomenon of the liquid during the rising process. In addition, by gradually reducing the width of the flow guide structure 214, the lateral constraint on the liquid can be gradually reduced, so that the liquid can flow upward more smoothly. In addition, the gradually decreasing width of the flow guide structure 214 can also provide a gradually decreasing guide path during the rising of the liquid, so that the impurities and the liquid are gradually separated during the flow process, and the liquid can be smoothly guided to the vicinity of the through hole 213 for discharge. On the contrary, if the width of the flow guide structure 214 remains unchanged, it may cause the liquid to slow down or the impurities to accumulate in the middle and rear sections of the flow path, thereby reducing the separation efficiency. Finally, the design of the gradually decreasing width of the flow guide structure 214 also helps to continuously maintain a high flow speed and kinetic energy during the rising of the liquid, ensuring that the liquid still has sufficient kinetic energy for effective separation and discharge when approaching the through hole 213.

[0043] In an embodiment, the first driving element 212 is a servo motor; and / or, the cross-sectional area of the through hole 213 gradually decreases from the inner wall of the barrel 211 to the outer wall of the barrel 211.

[0044] In the embodiment, the through hole 213 is designed as a tapered hole that gradually narrows from the inner wall to the outer wall of the barrel 211. This design helps the liquid to be smoothly discharged under the action of centrifugal force, while reducing the resistance at the through hole 213. The tapered hole can ensure that the liquid can be quickly thrown out without being retained on the inner wall of the barrel 211 when rotating at high speed.

[0045] In an embodiment, referring to Figure 2 As shown in the figure, the bottom of the first filter unit 200 is provided with an accumulated liquid groove 220, and the side of the accumulated liquid groove 220 close to the second filter unit 300 is an inclined surface. The accumulated liquid groove 220 is in communication with the second filter unit 300.

[0046] In this embodiment, by setting the liquid accumulation groove 220, the liquid discharged from the first filtering unit 200 can be effectively collected and temporarily stored, and through the communication with the second filtering unit 300, the liquid is further guided into the second filtering unit 300 for secondary filtering treatment. This structural design not only optimizes the flow path of the liquid, reduces the possible stagnation problem of the liquid during the filtering process, and improves the filtering efficiency, ensuring that the filtering system can continuously and efficiently operate. In addition, the side of the liquid accumulation groove 220 facing the second filtering unit 300 is inclined, which can better converge the separated traditional Chinese medicine liquid, reduce the dispersion of the traditional Chinese medicine liquid in the liquid accumulation groove 220, and reduce the loss caused by the adhesion of traditional Chinese medicine in the liquid accumulation groove 220.

[0047] In an embodiment, referring to Figure 2 The extrusion module 310 includes an extrusion plate 311 and a second driving element 312, and the second driving element 312 is used to drive the extrusion plate 311 to move to apply force to the traditional Chinese medicine liquid.

[0048] In this embodiment, when the traditional Chinese medicine liquid enters the second filtering unit 300, the second driving element 312 can drive the extrusion plate 311 to move downward, and the extrusion plate 311 can contact and press the traditional Chinese medicine liquid, so as to extrude the traditional Chinese medicine liquid through the filter layer 320, thereby realizing the second filtering of the traditional Chinese medicine liquid.

[0049] In an embodiment, the side of the extrusion plate 311 facing the filter layer 320 is arched.

[0050] In this embodiment, the extrusion plate 311 is arched, which aims to better concentrate the force when the extrusion plate 311 applies pressure to the traditional Chinese medicine liquid, so that the liquid is more uniformly stressed and the pressure is greater. The arched structure can effectively reduce the possibility of the traditional Chinese medicine liquid scattering during extrusion, thereby improving the extrusion efficiency.

[0051] In an embodiment, referring to Figure 3 The filtering device further includes a backwashing unit 400, which is arranged on the lower side of the filter layer 320, and the backwashing unit 400 is used to spray water flow to the side of the filter layer 320 away from the first filtering unit 200. The backwashing unit 400 includes a pressurizing module and a pipeline, and the water flow flowing out of the pipeline is pressurized by the pressurizing module and then sprayed to the filter layer 320.

[0052] In the embodiment, when the pressing plate 311 presses the liquid to the filter layer 320, part of the tissue impurities can be blocked in the filter layer 320, which affects the filtering efficiency of the filter layer 320, therefore, in the embodiment, a backwashing unit 400 is arranged at the lower side of the filter layer 320, and water flow is sprayed into the first filtering unit 200 through the backwashing unit 400, so as to blow out the impurities blocked in the filter layer 320.

[0053] Further, in an embodiment, referring to Figure 3 As shown in the figure, the filter layer 320 is also connected with a third driving element 330, the third driving element 330 is used to drive the filter layer 320 to rotate, the side of the filter layer 320 is provided with a recovery box 110, the recovery box 110 is used to recover the impurities blocked in the filter layer 320. The third driving element 330 can also be a servo motor.

[0054] In the embodiment, the filter layer 320 is driven to rotate by the third driving element 330, so that in the process of backwashing, the filter layer 320 can be rotated by a certain angle, for example, the filter layer 320 is rotated from the horizontal state to the inclined state, so that the impurities blown out of the filter layer 320 can flow into the recovery box 110; when the filter layer 320 is backwashed, the third driving element 330 rotates the filter layer 320 to the horizontal direction again.

[0055] The technical features of the above embodiments can be combined arbitrarily, in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered that it is within the scope of the present application.
