Description

Technical Field

[0001] The present invention relates to the technical field of filtering equipment, and particularly to a fine processing filter for veterinary drug stock solution. Background Art

[0002] The fine processing filter for veterinary drug stock solution is a key equipment in the veterinary drug production process to ensure the product purity and quality safety. Its core lies in removing particles, microorganisms and macromolecular impurities in the stock solution through fine filtration. As the mainstream technical form, membrane filtration occupies an important position in the fine processing of veterinary drugs by virtue of its high-efficiency separation characteristics. This technology mainly relies on polymer membranes with different pore sizes and materials to achieve selective permeation. Among them, microfiltration (MF) intercepts suspended particles and microorganisms with pore sizes of 0.1 - 10 microns, ultrafiltration (UF) further separates impurities such as proteins and colloids through pore sizes in the range of 1 - 100 nanometers, while nanofiltration (NF) and reverse osmosis (RO) are used for precise regulation of smaller molecules. Membrane materials are often selected as polymers such as polyethersulfone and polyvinylidene fluoride, which are resistant to chemical corrosion and high temperature, to adapt to the complex components of veterinary drug stock solution.

[0003] For the existing fine processing filters for veterinary drug stock solution, during use, the filter element usually needs to be cleaned to improve the filtration effect and efficiency. However, different cleaning methods usually have problems such as inconvenient cleaning and insufficient cleaning. Especially when the filter element is severely dirty, it is more difficult to clean thoroughly, which affects the filtration effect and even causes secondary pollution, making it inconvenient to use. Therefore, in view of the above current situation, there is an urgent need to develop a fine processing filter for veterinary drug stock solution to overcome the deficiencies in current practical applications.

Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0054] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0055] Please refer to Figures 1 - 12 , a veterinary drug stock solution fine processing filter provided by an embodiment of the present invention, the filter includes a filter element frame 3, and an adjustment chamber 2 and a mounting base plate 6 are respectively fixedly installed at both ends of the filter element frame 3;

[0056] Moreover, a plurality of flip filter ports 5 are also opened on the filter element frame 3, and a filter membrane 4 is arranged in each flip filter port 5, and a positioning baffle 8 is arranged on the filter membrane 4;

[0057] Wherein, a sealing assembly is further arranged on the filter membrane 4 when the edge of the filter membrane 4 abuts against the filter element frame 3, and the filter element frame 3, the filter membrane 4 and the sealing assembly can form a stock solution filtering space;

[0058] and a flipping control component, which is located in the adjustment chamber 2 and is connected to a plurality of the positioning baffles 8. The flipping control is used to drive a plurality of filter membranes 4 to rotate in the flipping filter openings 5 for replacing the filtering surface, and the positioning baffle 8 is used to position the filter membrane 4 after the filtering surface is replaced.

[0059] In an embodiment of the present invention, please refer to Figures 1 - 12 , the filter further includes: a cover plate 1, which is detachably connected to the adjustment chamber 2;

[0060] and a liquid inlet pipe 7, one end of the liquid inlet pipe 7 is connected to the mounting base plate 6 and is communicated with the raw liquid filtration space.

[0061] When filtering the veterinary drug stock solution, first install the entire filter element on the filtering device and connect it to the external stock solution to be filtered through the liquid inlet pipe 7. After the stock solution enters the stock solution filtering space through the liquid inlet pipe 7, under the filtering action of multiple filter membranes 4, the stock solution can be fully filtered. When the filter membrane 4 becomes blocked, especially severely blocked, the continuous supply of the stock solution can be stopped and the flipping control assembly can be activated, enabling multiple filter membranes 4 to rotate 180° around the central axis of the filter membrane 4 simultaneously in multiple flipping filter ports 5, so that the filtering surface originally located inside the stock solution filtering space is flipped to the outside. At this time, the flipped filter membrane 4 is positioned by the positioning baffle 8 to prevent shaking during subsequent cleaning and filtering operations. The sealing assembly contacts the wall surface of the filter element frame 3 again after flipping, thereby forming a new stock solution filtering space again. Then, clean water or cleaning agent is introduced into the new stock solution filtering space through the liquid inlet pipe 7 to perform a backwashing effect on multiple filter membranes 4. At the same time, according to the blocking situation of the filter membrane 4 and the cleaning situation, while backwashing multiple filter membranes 4, external conventional wiping supplies such as a soft brush or a sponge can also be used to wipe and clean the flipped filtering surface. Among them, the soft brush is located outside the filter membrane 4 and can be reciprocally wiped and cleaned on the outer surface of the filter membrane 4 in a pneumatic or electric lifting manner. During normal cleaning, the soft brush is stored in the upper part of the adjustment chamber 2 to avoid secondary pollution of the filtered liquid (for example, one connection method that the soft brush can adopt is: a guide rail is provided at the outer side part of the filter element, and the soft brush is slidably connected to the guide rail through a sliding seat. During normal filtering, the brush shrinks to a position near the top of the adjustment chamber 2, and during cleaning, it is driven by a cylinder to descend along the guide rail to the outer surface of the filter membrane). The above are all existing products and existing technologies, and will not be elaborated here. By combining the two cleaning methods of backwashing and wiping, it can ensure that the original filtering surface of the filter membrane 4 is fully cleaned. For example, after the filter membrane 4 is flipped, high-pressure clean water (0.3 - 0.5 MPa) is introduced through the liquid inlet pipe 7 for backwashing, and at the same time, the external soft brush reciprocally wipes the outer surface of the filter membrane at a frequency of 30 - 60 times per minute. Backwashing and wiping are carried out simultaneously for 3 - 5 minutes to restore the membrane flux and improve the filtering efficiency. Moreover, by combining internal flushing and external wiping, the cleaning agent can be used more efficiently, the cleaning cost can be reduced, the cleaning efficiency can be improved, and the cleaning time can be shortened. In addition, through the flipping cleaning method, the inner and outer surfaces of the filter membrane 4 can alternately bear the pressure of filtering and cleaning, avoiding excessive unilateral wear, extending the overall service life, and preventing the long-term accumulation of pollutants from causing membrane material aging or performance degradation. Especially for high-viscosity liquids, flipping the membrane surface for cleaning can effectively prevent the rapid accumulation of pollutants on the membrane surface. The operation is simple and does not require disassembly and assembly for cleaning, providing convenience for the staff.

[0062] In an embodiment of the present invention, please refer to Figures 1 - 12 , the flipping control assembly includes:

[0063] A first rotation shaft 9 is fixedly installed at the end of the filter membrane 4;

[0064] One end of the first rotation shaft 9 penetrates through the adjustment chamber 2 and extends into the adjustment chamber 2. An adjustment gear 18 is fixedly installed on one end of the first rotation shaft 9, and the first rotation shaft 9 is connected to the sealing assembly;

[0065] And a driving member 11, the driving member 11 is located in the adjustment chamber 2, and a rotating shaft 17 is fixedly installed on the output end of the driving member 11. The rotating shaft 17 is rotatably connected to the adjustment chamber 2;

[0066] A driving gear 22 is fixedly installed on the rotating shaft 17, and the driving gear 22 is connected to a plurality of the adjustment gears 18.

[0067] It further includes: a rotation angle detector 20, the rotation angle detector 20 is fixedly installed in the adjustment chamber 2 and is connected to the rotating shaft 17.

[0068] When the filter membrane 4 needs to be flipped, the driving member 11 is started, which can drive the rotating shaft 17 and the driving gear 22 to rotate. Under the action of meshing transmission, a plurality of adjustment gears 18 are driven to rotate simultaneously, so as to drive the filter membrane 4 to rotate in the flipping filter opening 5, realizing the flipping of the filtering surface on the filter membrane 4. In addition, through the provided rotation angle detector 20, the rotation angle and speed of the rotating shaft 17 can be detected, so as to ensure the accuracy of the flipping position, and when jamming occurs, the driving member 11 can be controlled to stop in time, thus ensuring the smooth flipping of the filter membrane 4. Among them, the rotation angle detector can adopt the form of a high-precision photoelectric encoder, be directly connected to the rotating shaft 17 through a flange, and transmit real-time angle data to the PLC controller through the CAN bus, which will not be elaborated here.

[0069] In an embodiment of the present invention, please refer to Figures 1 - 12 , the sealing assembly includes:

[0070] A flexible sealing strip 26, the flexible sealing strip 26 is sleeved on the filter membrane 4 and the positioning baffle 8. When normal filtering work is carried out, the flexible sealing strip 26 abuts against the wall surface of the filter element frame 3;

[0071] And an elastic sealing ring 28, the elastic sealing ring 28 is detachably connected to the first rotation shaft 9, and the elastic sealing ring 28 is also connected to the flexible sealing strip 26.

[0072] A support 24 is fixedly installed on the filter membrane 4, and the support 24 is rotatably connected to the installation base plate 6 through a second rotation shaft 27;

[0073] Among them, an elastic sealing ring 28 is also arranged on the second rotation shaft 27. During normal filtration work, the support 24 and the second rotation shaft 27 are respectively in contact with the filter element frame 3 through a flexible sealing strip 26 and an elastic sealing ring 28.

[0074] During the rotation of the filter membrane 4, through the arranged support 24 and the second rotation shaft 27, the smooth rotation of the filter membrane 4 can be ensured. After the flipping is completed and just reaches the flipping position, the flexible sealing strip 26 and the elastic sealing ring 28 will contact the wall surface of the filter element frame 3. Under the extrusion effect, the flexible sealing strip 26 and the elastic sealing ring 28 will produce certain deformation. Thus, under the elastic action of the flexible sealing strip 26 and the elastic sealing ring 28 themselves, the sealing effect at the connection between the filter membrane 4 and the filter element frame 3 is ensured. Of course, other existing sealing technologies can also be adopted, as long as the sealing function after the flipping of the filter membrane 4 can be realized, and specific limitations are not made here.

[0075] In an embodiment of the present invention, please refer to Figures 1 - 12 , four positioning sockets 25 are arranged on the positioning baffle 8. During normal filtration work, a lifting drive assembly for positioning two of the positioning sockets 25 is further arranged on the adjustment bin 2;

[0076] The lifting drive assembly is also connected to the flipping control assembly. Among them, before the flipping control assembly drives the filter membrane 4 to rotate around the central axis of the filter membrane 4 in the flipping filter opening 5, it will drive the lifting drive assembly to act and release the positioning effect on the positioning socket 25.

[0077] The lifting drive assembly includes:

[0078] Non-engaging notches 23, the number of the non-engaging notches 23 is multiple, and multiple non-engaging notches 23 are all located on the drive gear 22. At the initial stage of the start of the driving member 11, multiple adjusting gears 18 are respectively arranged opposite to multiple non-engaging notches 23;

[0079] A boss 21, the boss 21 is fixedly connected to the rotating shaft 17 and the drive gear 22 respectively, and a rotating seat 12 is fixedly installed on the boss 21;

[0080] An annular convex portion 13, the annular convex portion 13 is fixedly installed on the rotating seat 12, and multiple guiding grooves 14 are arranged on the annular convex portion 13;

[0081] And a positioning and inserting unit, the positioning and inserting unit is connected to the adjustment bin 2 and is respectively slidably connected to the annular convex portion 13 and the guiding grooves 14;

[0082] And during normal filtration operation, the positioning and inserting unit is inserted and connected to the positioning socket 25. At this time, the positioning and inserting unit contacts the guiding groove 14.

[0083] The positioning and inserting unit includes:

[0084] A positioning insert piece 10, which penetrates through the adjustment bin 2 and is slidably connected to the adjustment bin 2. And during normal filtration operation, the positioning insert piece 10 is inserted into the positioning socket 25;

[0085] And a smooth rod 15, one end of the smooth rod 15 is connected to the positioning insert piece 10, and the other end of the smooth rod 15 is slidably connected to the annular convex portion 13 and the guiding groove 14 respectively. During normal filtration operation, the smooth rod 15 is located in the guiding groove 14;

[0086] And a pressure sensor and a position sensor are further arranged on the smooth rod 15.

[0087] It further includes: an adsorbing member 19, which is fixedly installed in the adjustment bin 2;

[0088] And a magnetic connecting plate 16, which is respectively connected to the positioning insert piece 10 and the smooth rod 15, and a magnetic attraction force can be generated between the magnetic connecting plate 16 and the adsorbing member 19.

[0089] After the driving member 11 is started, where the driving member 11 can be in the form of a motor, while the driving member 11 drives the rotating shaft 17 and the driving gear 22 to rotate, it also drives the rotating seat 12 and the annular convex portion 13 to rotate. Due to the non-engaging notch 23 provided on the driving gear 22, at the initial stage of the rotation of the driving gear 22, since the non-engaging notch 23 contacts the adjusting gear 18, the adjusting gear 18 will not rotate at this time. During the rotation of the rotating seat 12 and the annular convex portion 13, a thrusting action will be exerted on the smooth rod 15 through the guiding groove 14, so that the smooth rod 15 generates an upward sliding action in the guiding groove 14 and finally slides from the bottom of the guiding groove 14 to the upper surface of the annular convex portion 13. During this process, the smooth rod 15 will drive the positioning insert 10 to move upward and immediately separate from the positioning socket 25 on the positioning baffle 8. Among them, the upward movement of the positioning insert 10 is realized by the thrusting action of the guiding groove 14, and the downward movement of the positioning insert 10 in the guiding groove 14 (realizing the insertion of the positioning insert 10 into the positioning socket 25) can be realized by the gravity and other actions of the positioning insert 10 itself. In addition, a position sensor is provided on the smooth rod 15. When in the low position, that is, at the bottom of the guiding groove 14, the driving member 11 can be controlled to start with a large torque and speed, so as to smoothly push the smooth rod 15 from the guiding groove 14 to the upper surface of the annular convex portion 13. When the smooth rod 15 reaches the upper surface of the annular convex portion 13, that is, in the high position, the position sensor will reduce the torque and speed of the driving member 11, so that the filter membrane 4 rotates with a relatively slow and stable movement, avoiding impurities being thrown to other positions of the equipment during the rotation process, increasing the cleaning difficulty. At the same time, the number of positioning sockets 25 on each positioning baffle 8 is four. The positioning sockets 25 symmetrically arranged on both sides of the first turning shaft 9 are in a group. During normal filtration operation, the positioning insert 10 will be inserted into the two positioning sockets 25 located on the inner side of the positioning baffle 8, that is, the two positioning sockets 25 located in the raw liquid filtration space, so as to avoid the rapid accumulation of impurities in the positioning sockets 25 and ensure subsequent positioning work. Then, the insertion fit between the positioning insert 10 and the positioning socket 25 can prevent the filter membrane 4 from rotating or slightly shaking due to the pressure during filtration, flushing or wiping;

[0090] Moreover, under the positioning effect between the positioning insert 10 and the positioning socket 25, it can ensure that the filter membrane 4 rotates to the optimal position. On the one hand, it can ensure that the filtration surface evenly filters the stock solution. On the other hand, it can ensure that the flexible sealing strip 26 works in the best sealing state, thus ensuring the sealing performance during the filtration process. In addition, through the provided magnetic connecting plate 16 and the attracting member 19, wherein both the magnetic connecting plate 16 and the attracting member 19 can be in the form of magnets. Under the action of the magnetic attraction force between the two and in cooperation with the gravity of the positioning insert 10, it can ensure the stability of the positioning insert 10 inserted in the positioning socket 25, thereby further ensuring the positioning effect. And since the smooth rod 15 is located in the guiding groove 14, the magnetic connecting plate 16 and the attracting member 19 are closest in position and the magnetic attraction force is the strongest, the positioning effect can be fully ensured. On the other hand, through the pressure sensor provided on the smooth rod 15, when the smooth rod 15 is located in the guiding groove 14, the distance between the magnetic connecting plate 16 and the attracting member 19 is the closest and the magnetic attraction force is the strongest, then the pressure of the smooth rod 15 on the wall surface of the guiding groove 14 is the largest, thus reaching the set value. At this time, subsequent filtration or cleaning operations can be carried out. When the smooth rod 15 is located on the upper surface of the annular convex portion 13, the pressure value detected by the pressure detector is smaller, so that the relevant equipment for filtration or cleaning will not be started, thus achieving the purpose of precise control. At the same time, it can also be judged whether the smooth rod 15 reaches the specified position, that is, whether the positioning insert 10 is normally inserted into the positioning socket 25 according to the detected value, so as to facilitate the staff to check and troubleshoot in time.
