[0002] In the field of pharmaceutical processing, the performance of filtration equipment is directly related to production efficiency and product quality. However, traditional filtration equipment often faces the problem of low efficiency when processing large quantities of medicinal materials. These problems are mainly manifested in the following aspects: First, the design of traditional filtration equipment often adopts a fixed structure, which cannot achieve continuous production, resulting in frequent shutdowns to clean the filter screen when processing large quantities of medicinal materials, which seriously reduces production efficiency. Secondly, the screening accuracy of traditional filtration equipment is limited, and it is difficult to effectively remove impurities in medicinal material particles, affecting the quality of the final product. In addition, traditional filtration equipment is prone to filter clogging during operation, especially when processing medicinal materials containing more impurities, the clogging phenomenon is particularly serious, further reducing the filtration efficiency.

[0022] 1. High-efficiency filtration improves production efficiency: When processing large quantities of medicinal materials, traditional filtration equipment often needs to be frequently shut down to clean the filter screen, which seriously reduces production efficiency. However, this equipment realizes the directional reciprocating motion of the filter component by adopting a combined design of the transmission component and the filter component. The motor rotates coaxially with the driving shaft through the traction pulley, driving the filter component to perform continuous cyclic motion, thereby realizing continuous production. This design not only reduces downtime, but also significantly increases the filtration speed, greatly improving production efficiency.

[0023] 2. Accurate screening to ensure product quality: The filter component of the equipment adopts an oblique design and has a filter chamber inside, which can achieve directional screening and filtration with the reciprocating motion of the transmission component. This design allows the medicinal material particles to contact the filter more evenly and accurately during the filtration process, thereby effectively removing impurities. At the same time, the angle and movement trajectory of the filter component are precisely designed to ensure the accuracy of the screening and avoid product quality problems caused by inaccurate screening in traditional equipment.

[0024] 3. Reduce filter clogging and reduce maintenance costs: When traditional filtration equipment processes medicinal materials containing a lot of impurities, the filter is prone to clogging, resulting in frequent equipment shutdowns for cleaning and increased maintenance costs. This equipment reduces the occurrence of filter clogging by optimizing the structural design and movement of the filter components. The cyclic movement and oblique design of the filter components allow medicinal material particles and impurities to pass through the filter more smoothly, reducing the possibility of clogging and thus reducing the maintenance cost of the equipment.

[0025] 4. Instant filtration and differentiated feeding to improve the convenience of operation: The equipment is equipped with a square upward feeding port at the left end of the filter component, and guides the medicinal materials to the filter chamber through the L-shaped drainage chamber, realizing instant filtration. At the same time, the discharge chamber is located at the right end of the filter component, and multiple outlets on the edge can differentiate the feeding as the filter component circulates. This design not only improves the timeliness of filtration, but also makes the feeding process more convenient and orderly, reducing the need for manual intervention.

[0026] 5. Wide application range and strong flexibility: The design of this equipment is highly flexible and adaptable, and can be applied to different types of medicinal material particle filtering needs. By adjusting the movement speed of the transmission component and the angle of the filter component, accurate filtering of different particle sizes and impurity contents can be achieved. This flexibility makes this equipment have a wide range of application prospects in the field of pharmaceutical processing.

[0027] In summary, this filtration equipment realizes an efficient, continuous and precise filtration process through innovative design and structural optimization, significantly improving the production efficiency and product quality in pharmaceutical processing, while reducing maintenance costs, eliminating the filter structure that is easily clogged, and improving operational convenience. It has important practical significance and broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] Embodiment 1

[0044] To solve the technical problems in the background art, the following filtering equipment is provided:

[0045] Combined with Figures 1-7As shown in the figure, the filtering device includes a chassis 1 that bears the filtering component 3, a transmission component 2 is supported therebetween, and a feed hopper 4 and a discharge chamber 5 are installed at the front and rear ends of the filtering component 3. It can filter out impurities in the medicinal material particles. The transmission component 2 includes a motor 21 seated on the chassis 1, and a traction pulley 22 is connected to the power output end thereof. It rotates coaxially with the driving shaft 23 and can rotate to drive the filtering component 3 thereon to perform a reciprocating motion in a fixed direction, so as to realize the separation of impurities in the medicinal material particles;

[0046] The filtering component 3 includes an inclined filter box frame 31 mounted on the transmission component 2. A filter cavity 32 is arranged inside the filter box frame 31, and it can perform directional screening and filtering as it reciprocates with the transmission component 2;

[0047] The feeding port 41 includes a square upward feeding port 41, which turns to form an L-shaped diversion cavity 44 communicating with the left end of the filtering component 3, and can feed materials to guide them into the filter cavity 32 to achieve immediate filtering;

[0048] The discharge chamber 5 includes a hollow chamber body 57 connected to the right end of the filtering component 3, and a plurality of outlets are provided at its edge, and it can perform differential discharging as it circulates with the filtering component 3.

[0049] Please refer to the attached instruction manual Figures 1-7 This invention provides a first embodiment of a filtering device. In this embodiment, the filtering device mainly consists of parts such as a chassis 1, a transmission component 2, a filtering component 3, a feed hopper 4 and a discharge chamber 5. Through ingenious design and structural arrangement, this device realizes the efficient filtering of medicinal material particles. Specifically, the chassis 1 provides a solid support for the whole device, and a transmission component 2 is supported thereon, including a motor 21 seated on the chassis 1. A traction pulley 22 is connected to the power output end thereof and rotates coaxially with the driving shaft 23. This design enables the motor 21 to drive the driving shaft 23 to rotate through the traction pulley 22, thereby driving the filtering component 3 thereon to perform a reciprocating motion in a fixed direction, ensuring that impurities in the medicinal material particles can be effectively separated.

[0050] The filtering component 3 is one of the core parts of this device. It is mounted on the transmission component 2 and is arranged obliquely. A filter cavity 32 is arranged inside the filtering component 3, and it can perform directional screening and filtering as it reciprocates with the transmission component 2. This oblique design not only enhances the stability of filtering, but also enables the medicinal material particles to be more evenly distributed on the surface of the filter cavity 32, thereby improving the efficiency and accuracy of filtering.

[0051] In terms of the input and discharge of medicinal materials, the equipment is designed with a feed hopper 4 and a discharge chamber 5. The feed hopper 4 includes a feeding opening 41 facing upward in a square shape, which turns to form an L-shaped drainage cavity 44 and is connected to the left end of the filtering component 3. This design enables the medicinal materials to be smoothly guided to the filtering cavity 32 for immediate filtration. The discharge chamber 5 is connected to the right end of the filtering component 3 and is a hollow chamber body 57 with multiple outlets provided at the edge. These outlets can discharge materials differently along with the cyclic movement of the filtering component 3, ensuring that the filtered medicinal material particles can be discharged orderly along the preset path.

[0052] Through the reasonable design and coordinated operation of the above structure, the filtering equipment can effectively achieve efficient filtration of medicinal material particles. The driving component 2 driven by the motor 21 drives the filtering component 3 to perform a reciprocating movement in a fixed direction. Combining with the obliquely designed filtering box frame 31 and the carefully designed filtering cavity 32, the effective separation of impurities is ensured. At the same time, the ingenious design of the feed hopper 4 and the discharge chamber 5 makes the input and discharge of medicinal materials more convenient and efficient.

[0053] Embodiment Two

[0054] As Figures 3-6 and Figure 13 shown, on the basis of the above embodiment, the present embodiment further gives the following content:

[0055] In the present embodiment, a plurality of filtering cavities 32 are inserted in the filtering box frame 31. A material receiving port 321 adapted to the drainage cavity 44 is provided at the left end of the filtering cavity 32. The filtering cavities 32 are arranged vertically, forming multiple independent channels for filtering medicinal material impurities.

[0056] The feed hopper 4 includes a plurality of shunt gates 42 inserted at the front end of the drainage cavity 44, and a bent partition 43 corresponding to the shunt gates 42 is arranged in the drainage cavity 44. The bent partition 43 is connected to the same number of filtering cavities 32 as the shunt gates 42, and can guide a large number of medicinal material particles to enter the filtering component 3 synchronously in batches.

[0057] Please refer to the accompanying Figures 3-6 and Figure 13 , the present invention provides a second embodiment of a filtering device. In the present embodiment, the specific implementation manner of the filtering device is mainly reflected in the design of the filtering box frame 31 and the feed hopper 4. A plurality of filtering cavities 32 are inserted in the filtering box frame 31, and these filtering cavities 32 are arranged vertically. A material receiving port 321 adapted to the drainage cavity 44 is provided at the left end of the filtering cavity 32. The filtering cavities 32 are arranged vertically, forming multiple independent channels for filtering medicinal material impurities. This arrangement enables the medicinal material particles to flow between multiple filtering cavities 32, thereby achieving effective filtration and separation of impurities.

[0058] The design of the feed hopper 4 further optimizes the guiding and distribution process of the medicinal materials. The feed hopper 4 is inserted into the front end of the diversion cavity 44 and is provided with a plurality of diversion gates 42. These diversion gates 42 correspond to the curved partition plates 43 arranged in the diversion cavity 44, ensuring that a large number of medicinal material particles can enter the filtering component 3 in batches synchronously. Specifically, the number and positions of the diversion gates 42 are adapted to the number of filter cavities 32, so that the medicinal material particles can be evenly distributed in each filter cavity 32, avoiding the situation of overloading a single filter cavity 32.

[0059] Through this design, when the medicinal material particles enter the filtering component 3, they will be guided by the diversion gates 42 and the curved partition plates 43 to different filter cavities 32. The up-and-down arrangement between the filter cavities 32 enables the medicinal material particles to be screened directionally during the flowing process, thereby effectively removing impurities. At the same time, the parallel operation of multiple filter cavities 32 improves the overall filtering capacity of the equipment, making the processing of a large number of medicinal materials more efficient.

[0060] In addition, the connection design between the feed hopper 4 and the diversion cavity 44 also ensures smoother guiding of the medicinal materials. The L-shaped turn of the diversion cavity 44 enables the medicinal material particles to flow naturally towards the filter cavity 32, while the cooperation of the diversion gates 42 and the curved partition plates 43 makes the distribution of the medicinal materials more uniform and orderly. This design not only improves the filtering efficiency but also reduces the blockage and accumulation of the medicinal materials during the flowing process, ensuring the continuous operation of the equipment.

[0061] In summary, through the setting of multiple filter cavities 32 on the filter box frame 31 and the combination of the diversion gates 42 and the curved partition plates 43 in the feed hopper 4, this filtering equipment realizes the efficient filtering and batch processing of a large number of medicinal material particles. This design enables the medicinal material particles to be evenly distributed in multiple filter cavities 32, ensuring the high efficiency and continuity of the filtering process, and at the same time improving the overall processing capacity and operation stability of the equipment.

[0062] Embodiment Three

[0063] As Figures 7-11 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0064] In this embodiment, as a preferred technical solution of the present invention, a small crank 231 is sleeved on the driving shaft 23, and a long connecting rod 26 is arranged on the outer circumference of the small crank 231. The small crank 231 is circumferentially wrapped with a crank sleeve 261, and a bearing 262 is arranged therebetween. The end of the crank sleeve 261 is inserted with a telescopic connecting rod shaft 263. The head end of the connecting rod shaft 263 extends upward with a rotating shaft 27 and abuts against the front end of the filter box frame 31, and can drive the front end of the filter box frame 31 to lift and cycle along with the rotation of the crank.

[0065] A square hollow steel frame 6 is sandwiched between the filter box frame 31 and the rotating shaft 27, and a sleeve hole 61 is attached to the front end of the steel frame 6 and is hinged to the rotating shaft 27. A front fulcrum 62 and a rear fulcrum 63 are symmetrically arranged at the bottom of the steel frame 6, and a front swing arm 24 and a rear swing arm 25 are hinged downward through the front fulcrum 62 and the rear fulcrum 63. The front swing arm 24 and the rear swing arm 25 are connected and fixed by a connecting rod, and a swing shaft 241 is sleeved at the bottom, which can drive the filter box frame 31 to swing back and forth with the rotation of the crank to screen out impurities.

[0066] The base frame 1 is symmetrically provided with a front hook 28, and a corresponding rear hook 64 is provided at the rear end of the steel frame 6. A locking spring 29 is hung between the front hook 28 and the rear hook 64, which can rebound with the reciprocating screening movement of the filter box.

[0067] Please refer to the instruction manual Figures 7-11 The present invention provides a third embodiment of a filtering device. In this embodiment, the filtering device is mainly composed of a driving shaft 23, a small crank 231, a crank sleeve 261, a connecting rod shaft 263, a rotating shaft 27, a square hollow steel frame 6, a front fulcrum 62, a rear fulcrum 63, a front swing arm 24, a rear swing arm 25, a swing shaft 241, a bottom frame 1, a front hook 28, a rear hook 64, and a lock spring 29 hung therebetween. The specific implementation is as follows. In this embodiment, a small crank 231 is sleeved on the driving shaft 23, and a crank sleeve 261 is circumferentially wrapped around the outer periphery of the small crank 231, with a bearing 262 disposed therebetween. A retractable connecting rod shaft 263 is inserted at the end of the crank sleeve 261, and the head end of the connecting rod shaft 263 extends upward with a rotating shaft 27, and is top-connected with the front end of the filter box frame 31. When the crank rotates, the connecting rod shaft 263 can be extended and retracted accordingly, driving the rotating shaft 27 and the front end of the filter box frame 31 to perform lifting and lowering circulation movements.

[0068] A square hollow steel frame 6 is sandwiched between the filter box frame 31 and the rotating shaft 27, and a sleeve hole 61 is attached to the front end of the steel frame 6 and is hinged to the rotating shaft 27. The front fulcrum 62 and the rear fulcrum 63 are symmetrically arranged at the bottom of the steel frame 6, and the front swing arm 24 and the rear swing arm 25 are hinged downward through the front fulcrum 62 and the rear fulcrum 63. The front swing arm 24 and the rear swing arm 25 are connected and fixed by a connecting rod, and a swing shaft 241 is sleeved at the bottom. This design allows the connecting rod shaft 263 and the rotating shaft 27 to drive the front end of the filter box frame 31 to move up and down when the crank rotates. At the same time, the front swing arm 24 and the rear swing arm 25 are connected by the connecting rod and the swing shaft 241, driving the entire filter box frame 31 to swing back and forth from front to back in a directional manner. This swinging motion enables the filter chamber 32 of the filter box frame 31 to effectively screen out impurities in the medicinal material particles.

[0069] The front hooks 28 are symmetrically arranged on the chassis 1, and the corresponding rear hooks 64 are arranged at the rear end of the steel frame 6. A locking spring 29 is hung between the front hook 28 and the rear hook 64, which can perform insurance rebound along with the reciprocating sifting of the filter box body. The setting of the locking spring 29 ensures that the filter box frame 31 can smoothly return to the initial position during the swinging process, avoiding the problem that it is difficult to retract due to excessive swinging caused by external forces.

[0070] Furthermore, in this embodiment, the coordinated work of components such as the driving shaft 23, small crank 231, crank sleeve 261, connecting rod shaft 263, rotating shaft 27, square hollow steel frame 6, front fulcrum 62, rear fulcrum 63, front swing arm 24, rear swing arm 25, swing shaft 241, chassis 1, front hook 28, rear hook 64, and the locking spring 29 hung therebetween ensures that the filter box frame 31 can achieve the lifting cyclic motion at the front end and the reciprocating swing of the entire box frame under the drive of the crank. This motion mode enables the medicinal material particles to be evenly distributed in the filter box frame 31 and sift in multiple filter cavities 32, thereby realizing the effective filtration and separation of impurities.

[0071] To sum up, in this embodiment, through the reasonable design and coordinated work of components such as the driving shaft 23, small crank 231, crank sleeve 261, connecting rod shaft 263, rotating shaft 27, square hollow steel frame 6, front fulcrum 62, rear fulcrum 63, front swing arm 24, rear swing arm 25, swing shaft 241, chassis 1, front hook 28, rear hook 64, and the locking spring 29 hung therebetween, the lifting cyclic motion and reciprocating swing of the filter box frame 31 are realized. This design enables the medicinal material particles to be evenly distributed in multiple filter cavities 32, ensuring the high efficiency and continuity of the filtration process, and at the same time improving the overall stability and operation efficiency of the equipment.

[0073] As Figure 2 and Figure 10 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0074] In this embodiment, the discharge bin 5 includes a first outlet 51, a second outlet 52, and a third outlet 53 that are sequentially opened downward from front to back at the bottom. The front bevel angle of the first outlet 51 is smaller than that of the second outlet 52, and there is an upward fork between the second outlet 52 and the third outlet 53. The medicinal material particles fall into the first outlet 51 and the second outlet 52 after jitter screening, and the impurities fall into the third outlet 53.

[0075] A first deflector 55 is inserted into the side wall of the discharge bin 5 between the first outlet 51 and the second outlet 52, and a second deflector 56 is arranged in parallel between the second outlet 52 and the third outlet 53. Both the first deflector 55 and the second deflector 56 can move parallel along the edge of the filter cavity 32. They are in a human-shaped structure and can be independently adjusted according to the different specific gravities of the medicinal material particles and impurities.

[0076] A rotatable precision pointer 54 is inserted into the side wall of the first outlet 51. It penetrates the discharge bin 5 and is coaxially connected with a rotating plate 541, which can rotate and open / close to control the passing size of the first outlet 51 for high-precision screening of medicinal material particles.

[0077] Please refer to the attached Figure 2 and Figure 10 , The present invention provides a fourth embodiment of the filtering device. In this embodiment, the design of the discharge bin 5 mainly consists of a bottom outlet, deflectors, and a precision pointer 54, etc. The specific implementation is as follows.

[0078] In this embodiment, the discharge bin 5 includes a first outlet 51, a second outlet 52, and a third outlet 53 that are sequentially opened downward from front to back at the bottom. The front bevel angle of the first outlet 51 is smaller than that of the second outlet 52, and there is an upward fork between the second outlet 52 and the third outlet 53. This design enables the medicinal material particles to be separated according to the size and weight of the particles after jitter screening. The medicinal material particles fall into the first outlet 51 and the second outlet 52, while the impurities fall into the third outlet 53. This separation method ensures high-precision screening of the medicinal material particles.

[0079] A first deflector 55 is inserted into the side wall of the discharge bin 5 between the first outlet 51 and the second outlet 52, and a second deflector 56 is arranged in parallel between the second outlet 52 and the third outlet 53. Both the first deflector 55 and the second deflector 56 can move parallel along the edge of the filter cavity 32. They are in a human-shaped structure and can be independently adjusted according to the different specific gravities of the medicinal material particles and impurities. This design enables the deflectors to be flexibly adjusted according to actual needs, ensuring that the medicinal material particles and impurities can be accurately separated and fall into the corresponding outlets.

[0080] Furthermore, in this embodiment, a rotatable precision pointer 54 is inserted into the side wall of the first outlet 51. It penetrates the discharge bin 5 and is coaxially connected with a rotating plate 541. The precision pointer 54 can rotate and open / close to control the passing size of the first outlet 51. The design of the precision pointer 54 enables the opening degree of the first outlet 51 to be precisely adjusted, thereby achieving high-precision screening of the medicinal material particles.

[0081] In summary, through the reasonable design of the first outlet 51, the second outlet 52, and the third outlet 53 at the bottom of the discharge chamber 5 in this embodiment, combined with the flexible adjustment of the first deflector 55, the second deflector 56, and the precision pointer 54, it is ensured that the medicinal material particles and impurities can be separated according to their sizes and weights and fall into the corresponding outlets. This design makes the screening of medicinal material particles more accurate, and at the same time improves the overall efficiency and flexibility of the equipment.

[0082] Working principle and usage process of the present invention:

[0083] First, a large quantity of medicinal material particles are put into the equipment through the square feeding port 41. After the medicinal materials enter, they advance along the L-shaped diversion cavity 44. A plurality of diversion gates 42 are inserted at the front end of the diversion cavity 44, and curved partition plates 43 corresponding to the diversion gates 42 are provided. These diversion gates 42 and curved partition plates 43 guide the medicinal material particles in batches and evenly to the independent filter cavities 32, ensuring that a large quantity of medicinal materials can enter the filtering assembly 3 for processing synchronously.

[0084] Next, start the motor 21. The power output end of the motor 21 is connected with a traction pulley 22, and this pulley rotates coaxially with the driving shaft 23. When the driving shaft 23 rotates, the small crank 231 rotates accordingly, driving the telescopic movement of the crank sleeve 261. A telescopic connecting rod shaft 263 is inserted at the end of the crank sleeve 261. The head end of the connecting rod shaft 263 extends upward with a rotating shaft 27, which abuts against the front end of the filter box frame 31. As the crank rotates, the connecting rod shaft 263 and the rotating shaft 27 drive the front end of the filter box frame 31 to perform a lifting cyclic motion.

[0085] With the reciprocating motion of the transmission assembly 2, the filter box frame 31 performs directional screening and filtering accordingly. When the crank rotates, the front swing arm 24 and the rear swing arm 25 drive the entire filter box frame 31 to perform successive reciprocating directional swings from front to back, further realizing the screening of medicinal material particles and the separation of impurities.

[0086] During the filtering process, the medicinal material particles move along with the movement of the filter box frame 31 and roll and separate along the inclined filter cavity 32 according to their specific gravities and particle sizes. The screened medicinal material particles and impurities fall into different sections of the discharge chamber 5 along with the swing of the filter box frame 31. After the medicinal material particles are screened by jittering, they fall into the first outlet 51 and the second outlet 52 according to their particle sizes and weights, while the impurities fall into the third outlet 53.

[0087] During the discharging process, both the first deflector 55 and the second deflector 56 can move parallel to the edge of the filter cavity 32 and are independently adjusted according to the different specific gravities of different medicinal material particles and impurities. At the same time, in cooperation with the precision pointer 54, the turning plate 541 is flipped. The passing size of the first outlet 51 is controlled, thereby realizing the high-precision screening of medicinal material particles.

[0088] Through the above process, different medicinal material particles enter from the feeding port 41, and after shunting, filtering, and screening, they are finally separated and discharged from the first outlet 51 and the second outlet 52 of the discharge chamber 5, and the impurities are separated and discharged from the third outlet 53, completing the entire filtering process.

[0089] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
