Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, and more specifically, to a medicine filtration machine. Background Technology

[0002] In the process of decocting traditional Chinese medicine, filtration devices for the decoction liquid are widely used. Currently, most filtration devices on the market use manual or semi-automatic methods to complete the filtration and cleaning operations. While these devices can meet basic filtration needs to a certain extent, the process of disassembling and assembling the filter screen is cumbersome, often leading to low cleaning efficiency. Furthermore, frequent disassembly and assembly of the filter screen can easily damage it, while also increasing the workload of the operators. Utility Model Content

[0003] The main objective of this invention is to provide a medicine filter to solve the problem of low cleaning efficiency of the filter device in existing medicine filters.

[0004] To achieve the above objectives, according to one aspect of the present invention, a drug filtration machine is provided, comprising a frame, a drug filtration device, and a cleaning device. The drug filtration device is connected to the frame and includes a filter element for filtering the drug solution. The filter element is rotatable relative to the frame so that the filter surface of the filter element flips from facing upwards to facing downwards. The cleaning device is connected to the drug filtration device and is located above the filter element. When the filter surface is facing downwards, the cleaning device sprays cleaning liquid downwards to clean the filter element.

[0005] Furthermore, the cleaning device includes a first cleaning component, which is connected to the filter device and located at the inlet of the filter device. The first cleaning component has a first spray nozzle, through which the first cleaning component sprays cleaning liquid into the filter device and cleans the filter device.

[0006] Furthermore, the cleaning device also includes a second cleaning element, which is located between the first cleaning element and the filter element and is used to clean the filter element. When the second cleaning element sprays, it forms a spray area covering the filter element.

[0007] Furthermore, the second cleaning component has multiple second spray nozzles, which together form a spray area when spraying.

[0008] Furthermore, the second cleaning element has a curved surface that protrudes away from the filter element, and each second spray nozzle is distributed on the curved surface.

[0009] Furthermore, the filtration device also includes a rotary drive component, which is connected to the frame and driven by the filter element, and drives the filter element to rotate up and down.

[0010] Furthermore, the filtration device also includes: a drug storage space and a drug leakage port. The drug storage space is connected to the frame, and the filter element and cleaning device are located inside the drug storage space. The drug leakage port is located at the entrance of the drug storage space and above the filter element. The drug solution enters the drug storage space through the drug leakage port, and the first cleaning element is located between the inner wall of the drug storage space and the drug leakage port.

[0011] Furthermore, the filter also includes a discharge channel, a wastewater discharge channel, and a control component. The discharge channel is connected to the filter and is used to discharge the liquid medicine inside the filter. The wastewater discharge channel is connected to the discharge channel and is used to discharge wastewater. A connection position is formed between the discharge channel and the wastewater discharge channel. The control component is located on the discharge channel and / or the wastewater discharge channel and is located downstream of the connection position along the flow direction of the liquid medicine or wastewater.

[0012] Furthermore, the sewage discharge channel extends longitudinally, and the medicine discharge channel is bent and connected to the sewage discharge channel. The control component is located on the sewage discharge channel. The medicine filter also includes a medicine discharge drive component, which is located on the medicine discharge channel and drives the medicine liquid in the medicine discharge channel to flow out.

[0013] Furthermore, the filter also includes a drug inlet pipe, which is connected to the frame and delivers the drug solution to the filter device.

[0014] By employing the technical solution of this utility model, a flip-up filter element is designed so that the filter surface faces upwards when filtering the medicinal liquid and downwards when cleaning. This allows the residue on the filter surface to be washed away by gravity and the cleaning action of the cleaning liquid during cleaning, thus achieving automatic cleaning of the filter element and improving its cleaning efficiency and effectiveness. Specifically, when filtering the medicinal liquid, the liquid flows through the filter surface, leaving residue. After filtration, when cleaning is required, the filter element flips upside down so that the filter surface faces downwards, meaning the residue faces downwards. This downward orientation facilitates the residue falling off the filter surface. Combined with the cleaning device above the filter element spraying cleaning liquid, the residue is further dislodged by the cleaning liquid's impact, achieving automatic cleaning of the filter element. This improves cleaning efficiency and ensures effective cleaning, avoiding the low cleaning efficiency caused by disassembling the filter element for cleaning. It also reduces manual intervention and the workload of operators. Attached Figure Description

[0020] To address the problem of low cleaning efficiency of the filtration device in existing drug filter machines, this invention provides a drug filter machine.

[0021] like Figures 1 to 3 The illustrated drug filtration machine includes a frame 10, a drug filtration device 20, and a cleaning device 30. The drug filtration device 20 is connected to the frame 10 and includes a filter element 21 for filtering the drug solution. The filter element 21 can be flipped up and down relative to the frame 10 so that the filter surface of the filter element 21 flips from facing up to facing down. The cleaning device 30 is connected to the drug filtration device 20 and is located above the filter element 21. When the filter surface is facing down, the cleaning device 30 sprays cleaning liquid downward to clean the filter element 21.

[0022] This embodiment features a flip-up filter element 21, allowing the filter element 21 to face upwards when filtering the medicine and downwards when cleaning. This enables the medicine residue on the filter surface to be washed off by gravity and the cleaning action of the cleaning liquid during cleaning, thereby achieving automatic cleaning of the filter element 21 and improving its cleaning efficiency and effectiveness. Specifically, when filtering the medicinal liquid, the liquid flows through the filter surface, leaving residue on the filter surface. After filtration, when the filter element 21 needs to be cleaned, it flips upside down so that the filter surface faces downwards, meaning the residue on the filter surface faces downwards. This downward orientation of the residue facilitates its falling away from the filter surface. Combined with the cleaning device 30 above the filter element 21 spraying cleaning liquid onto it, the residue is dislodged from the filter surface by the cleaning impact of the cleaning liquid, thus achieving automatic cleaning of the filter element 21. This improves the cleaning efficiency of the filter element 21 and ensures its cleaning effect, avoiding the problem of low cleaning efficiency caused by disassembling the filter element 21 for cleaning. It also reduces manual intervention and the workload of operators.

[0023] like Figure 2 As shown, the filter element 21 in this embodiment is shaped like a bottle cap, meaning that the filter element 21 includes a bottom and a periphery. With the filter surface facing upwards, the periphery of the filter element 21 is located above the bottom, thus retaining the residue on the upper surface of the bottom when filtering the medicine. With the filter surface facing downwards, the bottom of the filter element 21 is located above the periphery, thus ensuring that the residue is located below the bottom of the filter element 21 during cleaning, facilitating its fall. Optionally, the filter element 21 can be configured as a filter screen.

[0024] It should be noted that the filter element 21 described in this embodiment can be flipped up and down, but this does not mean that the filter element 21 can only be flipped 180°. The filter surface can be set at the bottom and the periphery of the filter element 21, or it can be set at one of the bottom and the periphery of the filter element 21. For example... Figure 2 As shown, in this embodiment, the filter surface is located at the bottom of the filter element 21. When filtering the medicine, the filter surface can be set completely horizontally. When the filter element 21 is flipped up and down, it can be flipped at an angle greater than 90° and less than 270°, so that the filter surface faces downward. Preferably, when the filter element 21 filters the medicine, the filter surface of the filter element 21 is horizontal and facing upward. After flipping up and down, the filter surface is also horizontal and facing downward. That is, the filter element 21 is flipped up and down 180°, which facilitates the falling of the medicine residue, allowing the cleaning device 30 to thoroughly clean the filter element 21 and prevent medicine residue from remaining at the bottom and peripheral joints of the filter element 21.

[0025] In this embodiment, the cleaning device 30 includes a first cleaning component 31, which is connected to the filter device 20 and located at the inlet of the filter device 20. The first cleaning component 31 has a first spray nozzle, through which the first cleaning component 31 sprays cleaning liquid into the filter device 20, cleaning the filter device 20 and effectively removing residues from the filter device 20. This ensures that the filter device 20 is free of residues from the previous filtration, thus guaranteeing the quality of the filtration solution. Specifically, in this embodiment, the filter device 20 is placed vertically, with its inlet located at the top. This allows the first spray nozzle to spray cleaning liquid downwards, into the filter device 20, thereby cleaning any residues on the inner wall of the filter device 20.

[0026] It should be noted that spraying the cleaning fluid downwards from the first nozzle does not mean that the spray direction of the first nozzle can only be vertically downwards. The spray direction of the first nozzle can also form an angle of less than 90° with the vertically downward direction. When the spray direction of the first nozzle is vertically downwards, the first nozzle can form a spray area of ​​a certain size, which can cover the inner wall of the filter device 20, thereby cleaning the inner wall of the filter device 20. When the spray direction of the first nozzle forms an angle of less than 90° with the vertically downward direction, the spray direction of the first nozzle can be set to be directly towards the side wall of the filter device 20, thereby increasing the impact force on the side wall of the filter device 20 to ensure the cleaning effect. The specific adjustment can be made according to the actual situation.

[0027] Optionally, multiple first spray nozzles can be provided. Depending on the actual situation, the spraying direction of each first spray nozzle can be the same or different. For example, the spraying direction of each first spray nozzle can be vertically downward, or it can be that each first spray nozzle forms an angle of no more than 90° with the vertically downward direction. Alternatively, the spraying direction of the first spray nozzle can be partially vertically downward and partially form an angle of no more than 90° with the vertically downward direction.

[0028] like Figure 2As shown, in this embodiment, the cleaning device 30 further includes a second cleaning component 32, which is located between the first cleaning component 31 and the filter component 21, and is used to clean the filter component 21. When the second cleaning component 32 sprays, it forms a spray area covering the filter component 21, thereby achieving comprehensive cleaning of the filter component 21 and improving the cleaning efficiency and effect of the filter component 21. Specifically, in this embodiment, the second cleaning component 32 is disposed inside the filter device 20 and sprays cleaning liquid downwards. The spray area has a certain coverage range in the horizontal range, so that the horizontal area where the filter component 21 is located can be covered. That is, the projection of the filter component 21 on the horizontal plane is located within the projection range of the spray area on the horizontal plane, so that when the second cleaning component 32 sprays cleaning liquid, it can comprehensively clean the filter component 21, thereby ensuring the cleaning effect and cleaning efficiency of the filter component 21 and avoiding rework caused by incomplete cleaning.

[0029] like Figure 3 As shown, in this embodiment, the second cleaning component 32 has multiple second spray nozzles 321. When spraying, each second spray nozzle 321 collectively forms a spray area, thereby improving the uniformity of the cleaning fluid distribution within the spray area and enhancing the cleaning effect. Specifically, the second spray nozzles 321 are located on the side of the second cleaning component 32 closest to the filter element 21, allowing the spray direction of the second spray nozzles 321 to face the filter element 21 and form a spray area below the second cleaning component 32. Preferably, the second spray nozzles 321 are evenly distributed on the side of the second cleaning component 32 closest to the filter element 21 to ensure uniform distribution of the cleaning fluid. It should be noted that the cleaning fluid in this embodiment can be clean water or a liquid with added organic solvents for cleaning. Adjustments can be made according to actual needs to ensure the cleaning effect on the filter element 21. When using a liquid with added organic solvents as the cleaning fluid, it is important to rinse the filter device with clean water at the end to ensure no residue remains on the filter device.

[0030] In this embodiment, the second cleaning element 32 has a curved surface that protrudes away from the filter element 21, and each second spray nozzle 321 is distributed on the curved surface, thereby adjusting the spray direction of the second spray nozzle 321, thereby adjusting the angle of action when the cleaning liquid impacts the filter element 21, thereby generating a more effective coverage area and a stronger impact force, thereby improving the cleaning effect on the filter element 21, and at the same time increasing the distribution area of ​​the second spray nozzle 321 to facilitate the setting of more second spray nozzles 321. Specifically, in this embodiment, the side of the second cleaning element 32 closest to the filter element 21 is configured as a curved surface, and the curved surface is configured such that the middle region of the curved surface is farther away from the filter element 21 than the surrounding region. The spraying direction of the second spray nozzles 321 is perpendicular to the tangent of the local region of the curved surface, so that the spraying direction of the second spray nozzles 321 distributed at different positions on the curved surface is different. When the second spray nozzles 321 spray and clean the filter element 21, the second spray nozzles 321 together form a spray area that gradually shrinks from top to bottom, so that the filter element 21 can be rinsed by cleaning liquid from different directions, which is beneficial to improving the cleaning effect of the filter element 21. At the same time, within the same horizontal area, the curved surface is more advantageous than the flat surface in increasing the surface area, thereby providing a larger distribution area for the second spray nozzles 321, which is beneficial to the uniform and dense arrangement of the second spray nozzles 321, and further beneficial to improving the cleaning effect of the filter element 21. Moreover, the guidance of the spraying direction of the cleaning liquid by the curved surface can avoid the splashing and waste phenomena commonly seen in flat cleaning. Preferably, the curved surface is part of a sphere, and the sphere protrudes away from the filter element 21. This allows the cleaning liquid to be directed towards the location of the filter element 21 when the second spray nozzles 321 spray the cleaning liquid, ensuring that every corner of the filter element 21 is effectively cleaned. Of course, the specific shape of the curved surface can be adjusted according to the different shapes of the filter element 21 to ensure the cleaning effect of the filter element 21.

[0031] In this embodiment, the second cleaning component 32 further includes an inlet pipe and a storage cavity for storing cleaning fluid. A curved surface is disposed on the side of the storage cavity near the filter component 21, and the inlet pipe is disposed on the side of the storage cavity away from the filter component 21. This allows cleaning fluid to be injected into the top of the storage cavity and sprayed from the second spray port 321 at the bottom of the storage cavity. Optionally, multiple inlet pipes can be evenly arranged along the circumference of the storage cavity to improve the uniformity of cleaning fluid distribution within the storage cavity. The first cleaning component 31 is provided with an inlet for the entry of cleaning fluid. The inlet pipe of the second cleaning component 32 and the inlet of the first cleaning component 31 can be connected or independently configured.

[0032] In this embodiment, the filtration device 20 further includes a rotary drive 22, which is connected to the frame 10 and driven by the filter element 21. The rotary drive 22 drives the filter element 21 to rotate up and down, thereby achieving automatic rotation of the filter element 21, improving the cleaning effect of the filter element 21, and enhancing the automation level and ease of operation of the filtration machine. Specifically, a connecting bracket is provided on the frame 10, located around the filter element 21. The rotary drive 22 is fixed on the connecting bracket, enabling the rotary drive 22 to drive the filter element 21 to rotate around a horizontal axis of rotation, thereby achieving up and down rotation of the filter element 21. Optionally, the rotary drive 22 can be a rotary cylinder, servo motor, etc., to transmit power to the filter element 21, allowing the filter element 21 to automatically switch between filtering liquid and cleaning states.

[0033] In this embodiment, the filtration device 20 further includes a drug storage space 23 and a drug outlet 24. The drug storage space 23 is connected to the frame 10, and the filter element 21 and the cleaning device 30 are located within the drug storage space 23. The drug outlet 24 is located at the entrance of the drug storage space 23 and above the filter element 21. The medicine enters the drug storage space 23 through the drug outlet 24. The first cleaning element 31 is located between the inner wall of the drug storage space 23 and the drug outlet 24. Thus, the drug storage space 23 provides a temporary storage space for the medicine, facilitating the filtration operation within the drug storage space 23 and subsequent medicine processing. Simultaneously, the drug storage space 23 provides a cleaning space for the filter element 21 during cleaning. Specifically, in this embodiment, the drug storage space 23 is cylindrical and extends axially along the height direction. The bottom of the drug storage space 23 is funnel-shaped to facilitate the discharge of subsequent medicine or cleaning solution. The drug outlet 24 is also funnel-shaped and located at the top of the drug storage space 23 to facilitate the entry of medicine. The first cleaning component 31 is annular and fits around the outer periphery of the medicine leakage port 24, while being located on the inner periphery of the medicine storage space 23. This means there is an annular gap between the medicine leakage port 24 and the inner wall of the medicine storage space 23, and the first cleaning component 31 is positioned within this annular gap, allowing it to clean the inner wall of the medicine storage space 23. The first cleaning component 31 can be connected to the medicine leakage port 24, and its top has an annular overlap portion larger than the top diameter of the medicine storage space 23. This allows the first cleaning component 31 to overlap with the medicine leakage port 24 on the inner wall of the top of the medicine storage space 23, preventing both from falling into the medicine storage space 23. A through-hole can be provided in the central area of ​​the second cleaning component 32, allowing the bottom of the medicine leakage port 24 to pass through, preventing the second cleaning component 32 from obstructing the flow of the medicine through the filter element 21 during filtration.

[0034] like Figure 2As shown, in this embodiment, the filter machine further includes a discharge channel 40, a wastewater discharge channel 50, and a control component 80. The discharge channel 40 is connected to the filter device 20 and is used to discharge the liquid medicine inside the filter device 20. The wastewater discharge channel 50 is connected to the discharge channel 40 and is used to discharge wastewater. A connection position 41 is formed between the discharge channel 40 and the wastewater discharge channel 50. The control component 80 is located on the discharge channel 40 and / or the wastewater discharge channel 50, and is located downstream of the connection position 41 along the flow direction of the liquid medicine or wastewater. In this way, the arrangement of the discharge channel 40 and the wastewater discharge channel 50 realizes the separate discharge of liquid medicine and wastewater, thereby improving the cleanliness of the filter machine. Through the control of the control component 80, the orderly discharge of liquid medicine and wastewater can be achieved, avoiding cross-contamination. Optionally, the control component 80 can be set as a solenoid valve.

[0035] In this embodiment, the sewage discharge channel 50 extends longitudinally, and the medicine discharge channel 40 is bent and connected to the sewage discharge channel 50. The control component 80 is located on the sewage discharge channel 50. The filter also includes a medicine discharge drive component 60, which is located on the medicine discharge channel 40 and drives the medicine liquid in the medicine discharge channel 40 to flow out. In this way, through the coordinated cooperation of the control component 80 and the medicine discharge drive component 60, the medicine liquid and sewage are discharged in an orderly manner. Specifically, in this embodiment, the medicine discharge channel 40 is connected to the bottom of the filter device 20 and extends downward in a vertical direction, thereby facilitating the discharge of sewage containing medicine residue, cleaning fluid, etc. Compared with the sewage discharge channel 50 that is bent or extends in other directions, the sewage discharge channel 50 that is set in a vertical direction can reduce the residue of medicine residue on the inner wall of the channel. The discharge channel 40 can bend upwards at the connection point 41, meaning that the end of the discharge channel 40 near the sewage discharge channel 50 forms an angle greater than 90° with the vertically downward direction. This prevents sewage from entering the discharge channel 40 and causing contamination. The discharge drive component 60 can be used in conjunction with the control component 80, such as... Figure 2 As shown, in this embodiment, the control component 80 is installed on the sewage discharge channel 50. When discharging the liquid medicine, the control component 80 closes to prevent the liquid medicine from entering the sewage discharge channel 50, while the discharging drive component 60 opens to allow the liquid medicine to flow out of the discharging channel 40. When discharging wastewater, the discharging drive component closes, thereby closing the discharging channel 40, and the control component 80 opens to facilitate the wastewater to flow out of the sewage discharge channel 50. Optionally, the end of the discharging channel 40 away from the sewage discharge channel 50 can extend horizontally to reduce the difficulty of discharging the liquid medicine, or it can extend in other directions to facilitate guiding the liquid medicine to the next process. The end of the sewage discharge channel 50 away from the discharging channel 40 can be provided with a bent sewage outlet to guide the wastewater to a designated location. Optionally, the discharging drive component 60 can be a pump.

[0036] In this embodiment, the filter machine also includes a drug inlet pipe 70, which is connected to the frame 10 and transports the liquid medicine to the filter device 20, thereby realizing automatic delivery of the liquid medicine and improving the automation level and ease of operation of the equipment. The drug inlet channel can be set at the top of the frame 10, and the end of the drug inlet channel near the drug outlet 24 is located directly above the drug outlet 24, so that the liquid medicine containing the residue is pumped out directly above the drug outlet 24, and then the liquid medicine containing the residue can enter the filter device 20 from the drug outlet 24. After the residue is filtered out by the filter element 21, it enters the bottom of the storage space 23. At this time, the control element 80 on the drain channel 50 is in the closed state. After the filtration is completed, the drain channel 40 pumps out the filtered liquid medicine through the drain drive 60. At this time, the filter element 21 is rotated 180° under the drive of the rotation drive 22. The first cleaning component 31 sprays cleaning liquid through the gap between the inner wall of the medicine storage space 23 and the periphery of the medicine leakage port 24, thereby cleaning the inner wall of the medicine storage space 23. The second cleaning component 32 sprays cleaning liquid through the second spray port 321, thereby cleaning the filter device 20 in all directions. During cleaning, the control component 80 on the sewage discharge channel 50 is in the open state, and the sewage is directly discharged through the sewage discharge channel 50. Optionally, an air source can be provided on the side of the medicine discharge drive component 60 away from the sewage discharge channel 50. Air is blown into the medicine discharge channel 40 through the air source to drain the medicine liquid in the medicine discharge channel 40, avoiding the medicine liquid residue from affecting the cleanliness of the medicine liquid filtered on the next side. In this way, the filter machine can realize automatic filtration of Chinese medicine liquid, uninterrupted operation, and automatic cleaning.

[0037] It should be noted that "multiple" in the above embodiments refers to at least two.

[0038] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: 1. This invention solves the problem of low cleaning efficiency of the filter device in existing drug filter machines; 2. By setting a flip-up filter element, the filter element can face upwards when filtering the medicine and downwards when cleaning. This allows the medicine residue on the filter surface to be washed off due to gravity and the cleaning action of the cleaning liquid, thereby achieving automatic cleaning of the filter element and improving the cleaning efficiency and cleaning effect. 3. With the dregs facing downwards, they can fall off the filter surface. Combined with the cleaning device above the filter element spraying cleaning liquid onto the filter element, the dregs are removed from the filter surface by the cleaning impact of the cleaning liquid, thus achieving automatic cleaning of the filter element. This improves the cleaning efficiency of the filter element and ensures the cleaning effect. It avoids the problem of low cleaning efficiency caused by disassembling the filter element for cleaning, and at the same time reduces manual intervention and the workload of operators.
