Description

Technical Field

[0001] This application relates to the field of filtration technology in veterinary drug production, and specifically discloses a filtration device for veterinary drug production. Background Technology

[0002] Veterinary drugs refer to substances used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. Veterinary drugs mainly include serum products, vaccines, diagnostic products, microecological products, Chinese medicinal materials, prepared Chinese medicines, chemical drugs, antibiotics, biochemical drugs, radioactive drugs, and external insecticides and disinfectants.

[0003] Veterinary drug filtration is an important step in ensuring the quality of veterinary drug products. During the production process, veterinary drugs need to be filtered to remove raw material residues from the extract in order to ensure the purity and efficacy of the final product. In other words, it is necessary to separate the solid and liquid components of the veterinary drug and prioritize the removal of raw material residues from the extract.

[0004] The current problem is:

[0005] Impurities in the extract can easily clog the filter screen, causing a sharp drop in the extract's throughput and consequently affecting subsequent processing efficiency. Currently, there are many filtration devices to ensure that the extract's throughput does not drop sharply. This measure is effective, but it only addresses the symptoms, not the root cause.

[0006] Because the impurities in the extract only change position on the filter screen, but do not change the nature of the impurities in the extract remaining on the filter screen;

[0007] Therefore, utilizing downtime to quickly replace the filter screen, thereby increasing the replacement time and reducing the residence time of impurities in the extract on the filter screen, is the fundamental solution to ensure the efficient operation of veterinary drug production filtration equipment. However, the replacement of filter screens in existing veterinary drug production filtration equipment is too cumbersome and lacks quick disassembly and assembly capabilities. In view of this, this utility model provides a veterinary drug production filtration equipment to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to solve the problem that the replacement of filters in existing veterinary drug production filtration equipment is too troublesome and lacks quick disassembly and assembly functions, which leads to the inability of the filters to operate efficiently for a long time.

[0009] To achieve the above objectives, this utility model provides the following basic solution:

[0010] A veterinary drug production filtration device includes a housing, an end cap detachably connected to the housing, a drive assembly mounted on the end cap, a plurality of discharge ports disposed at the bottom of the housing, a rotating assembly disposed inside the housing and detachably connected to the drive assembly, a filter assembly mounted on the rotating assembly that does not rotate with the rotating assembly, and a contact assembly on the filter assembly for impurity agitation based on the rotation of the rotating assembly.

[0011] Furthermore, the drive assembly includes a motor, a mounting hole on the end cover, and a first bearing installed in the mounting hole. The output shaft of the motor passes through the first bearing and is connected to a rotating assembly inside the housing.

[0012] Furthermore, an annular locking block is fixedly connected to the bottom of the end cap, and an annular locking groove is provided on the top of the box body to cooperate with the annular locking block, and the annular locking groove engages with the annular locking block.

[0013] Furthermore, the rotating assembly includes a main shaft and a secondary shaft. The secondary shaft is sleeved on the main shaft, and a third bearing is provided between the secondary shaft and the main shaft. One end of the main shaft is detachably connected to the output shaft of the motor, and the other end of the main shaft is placed at the inner bottom of the housing and is sleeved with a second bearing. An installation sleeve is provided at the inner bottom of the housing, and the end of the main shaft sleeved with the second bearing is installed in the installation sleeve.

[0014] Furthermore, the external dimensions of the secondary shaft are larger than those of the main shaft, and several protrusions are fixedly attached to the outside of the secondary shaft. The filter assembly is detachably connected to the secondary shaft.

[0015] Furthermore, the filter assembly includes an outer frame, an inner frame, and a filter screen disposed between the outer frame and the inner frame. The inner frame has grooves with a number and position corresponding to the protrusions. The outer frame is fixedly connected to a plurality of hollow pull-up posts, which are in communication with the outer frame. The housing is fixedly connected to a snap-fit ​​post at the position corresponding to the hollow pull-up post, and the snap-fit ​​post is connected to the hollow pull-up post.

[0016] Furthermore, when the snap-fit ​​post is connected to the hollow pull-up post, the groove and the protrusion are misaligned.

[0017] Furthermore, the contact assembly includes a connecting shaft fixed to the main shaft below the filter assembly and a contact rod fixed perpendicularly to the connecting shaft, the contact rod contacting the lower surface of the filter screen.

[0018] Furthermore, several support columns are fixedly connected to the bottom of the box, and rubber anti-slip pads are fixedly connected to the free ends of the support columns.

[0019] Furthermore, a feed pipe is threadedly connected to the feed inlet, and the contact surface between the discharge outlet and the bottom of the box is an inclined surface, with the inclined direction of the inclined surface facing the center of the discharge outlet. A discharge pipe is threadedly connected to the discharge outlet.

[0020] The principle and effect of this solution are as follows:

[0021] 1. Compared with the prior art, the present invention has a new filter component. This filter component can not only realize the basic filtration function of veterinary drug filtration, but also has a quick-disassembly and quick-installation function compared with the traditional filter component. This solves the problem that the filter replacement in the existing veterinary drug production filtration equipment is too troublesome and does not have a quick-disassembly and quick-installation function, which leads to the filter not being able to operate efficiently for a long time.

[0022] 2. Compared with the prior art, this utility model is equipped with a driving component, and based on the driving component, a contact component is set to act under the filter component. By using the contact component, the impurities on the filter component are in dynamic condition, which avoids the filter component from clogging and ensures the pass rate of liquid effective veterinary drugs.

[0023] 3. Compared with the prior art, in order to avoid the influence of the drive component on the filter component, this device places the contact component at the bottom, which ensures the pass rate of liquid effective veterinary drugs while also ensuring the quick-release and quick-installation function of the filter component.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Implementation, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0031] A veterinary drug production filtration device includes a housing 1, an end cover 19 detachably connected to the housing 1, an inlet 23 disposed on the end cover 19, a drive assembly mounted on the end cover 19, a plurality of outlets 2 disposed at the bottom of the housing 1, a rotating assembly disposed inside the housing 1 and detachably connected to the drive assembly, a filter assembly mounted on the rotating assembly that does not rotate with the rotating assembly, and a contact assembly on the filter assembly for impurity sloshing based on the rotation of the rotating assembly.

[0032] The drive assembly includes a motor 21, a mounting hole on the end cover 19, and a first bearing 20 installed in the mounting hole. The output shaft of the motor 21 passes through the first bearing 20 and is connected to the rotating assembly inside the housing 1.

[0033] The rotating assembly is driven to rotate by the output shaft of motor 21;

[0034] An annular locking block 22 is fixedly connected to the bottom of the end cap 19, and an annular locking groove 6 is provided on the top of the box body 1 to cooperate with the annular locking block 22. The annular locking groove 6 is engaged with the annular locking block 22.

[0035] The rotating assembly includes a main shaft 7 and a secondary shaft 14. The secondary shaft 14 is sleeved on the main shaft 7, and a third bearing 18 is provided between the secondary shaft 14 and the main shaft 7. One end of the main shaft 7 is detachably connected to the output shaft of the motor 21, and the other end of the main shaft 7 is placed at the inner bottom of the housing 1 and is sleeved with a second bearing 8. An installation sleeve 3 is provided at the inner bottom of the housing 1, and the end of the main shaft 7 sleeved with the second bearing 8 is installed in the installation sleeve 3.

[0036] Specifically:

[0037] A third bearing 18 is provided between the secondary shaft 14 and the main shaft 7, so that the main shaft 7 rotates while the secondary shaft 14 does not rotate. The external dimensions of the secondary shaft 14 are larger than the external dimensions of the main shaft 7. Several protrusions 16 are fixed to the outside of the secondary shaft 14. The filter assembly is detachably connected to the secondary shaft 14.

[0038] Regarding the filtering components:

[0039] The filter assembly includes an outer frame 11, an inner frame 15, and a filter screen 12 disposed between the outer frame 11 and the inner frame 15. The inner frame 15 has grooves 17 in number and position that correspond one-to-one with the protrusions 16. Several hollow pull-up posts 13 are fixedly connected to the outer frame 11. The hollow pull-up posts 13 are in communication with the outer frame 11. The housing 1 is fixedly connected with snap-fit ​​posts 5 at the positions corresponding to the hollow pull-up posts 13. The snap-fit ​​posts 5 are connected to the hollow pull-up posts 13.

[0040] Specifically: When the snap-fit ​​post 5 is connected to the hollow pull-up post 13, the groove 17 and the protrusion 16 are misaligned.

[0041] The contact assembly includes a connecting shaft 9 fixed to the main shaft 7 below the filter assembly and a contact rod 10 fixed perpendicularly to the connecting shaft 9. The contact rod 10 contacts the lower surface of the filter screen 12. Several support columns 4 are fixed to the bottom of the housing 1, and rubber anti-slip pads are fixed to the free ends of the support columns 4.

[0042] A feed pipe is threaded onto the feed inlet 23. The contact surface between the discharge outlet 2 and the bottom of the box 1 is an inclined surface. The inclined direction of the inclined surface is towards the center of the discharge outlet 2. A discharge pipe is threaded onto the discharge outlet 2.

[0043] Specific implementation process:

[0044] The first step, just like Figure 1 and Figure 2 and Figure 3 As shown, when this device is installed, liquid veterinary drugs enter the housing 1 through the feed pipe and first fall onto the filter screen 12. The motor 21 is started, and the motor 21 drives the main shaft 7 to rotate. The rotation of the main shaft 7 causes the connecting shaft 9 on the main shaft 7 and the contact rod 10 fixed perpendicularly to the connecting shaft 9 to rotate. Since the contact rod 10 contacts the lower surface of the filter screen 12, the filter screen 12 undulates up and down, thereby keeping the impurities that cannot pass through the filter screen 12 in a dynamic state and preventing the filter screen 12 from clogging.

[0045] The second step is to remove the end cap 19 when the device has been filtering for a period of time or when waiting for the midday shutdown process. As the end cap 19 is removed, the motor 21 is also removed. Manually pull the hollow lifting column 13. After the hollow lifting column 13 is pulled up from the locking column 5, remove the filter assembly. The reason why the groove 17 and the protrusion 16 are misaligned is that the locking column 5 and the groove 17 and the protrusion 16 need to share the weight of the filter assembly.

[0046] The groove 17 and the protrusion 16 are misaligned. When the groove 17 and the protrusion 16 are installed in a misaligned manner, the snap-fit ​​post 5 and the hollow pull-up post 13 cannot be connected.

[0047] Specifically: the groove 17 and the protrusion 16 are to ensure that the hollow pull-up column 13 and the snap-fit ​​column 5 are connected when the staff installs the filter components, which is a foolproof measure.

[0048] The third step is to reinstall the filter assembly after cleaning, which completes the connection between the hollow pull-up column 13 and the snap-fit ​​column 5. If the inner frame 15 is simply placed on the secondary shaft 14, the groove 17 and the protrusion 16 may not be misaligned. In this case, the filter assembly will slide on the secondary shaft 14, and it can be seen that the hollow pull-up column 13 and the snap-fit ​​column 5 are not connected. This reminds the staff to reinstall the filter assembly.

[0049] This device solves the problem that the replacement of filters in existing veterinary drug production filtration equipment is too cumbersome and lacks quick disassembly and assembly functions, which leads to the filters not being able to operate efficiently for a long time.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
