Technical Field
[0001] This utility model relates to the technical field of impurity filtration devices, specifically an impurity filtration device for pharmaceuticals. Background Technology
[0002] Drug impurities are a critical factor that must be strictly controlled in drug research and development and production. They come from a variety of sources and are diverse in type, and can seriously affect the safety, efficacy and stability of drugs. Among them, drug impurity filtration devices are essential equipment in the pharmaceutical process, used to remove impurities, particles, microorganisms and other substances from drugs to ensure the purity and safety of drugs.
[0003] There are various impurity filtration devices available today. Some of these devices have filter bags inside their filter chambers. During use, water flow impacts the inside of the filter bags to achieve filtration. However, in actual use, because the water pumps in these devices are mostly pressurized (to ensure extraction efficiency), the retaining devices on the filter bags may loosen and fall off under the continuous impact of high-pressure fluid on the surface of the filter bags, thus affecting the subsequent filtration effect. Therefore, a new type of impurity filtration device for pharmaceuticals is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the problem that while there are various impurity filtration devices available, portable mobile filtration devices are the most common. However, although these portable filtration devices are easy to move, removing the filtered impurities is quite troublesome. This utility model provides an impurity filtration device.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] An impurity filtration device for pharmaceuticals includes: a fixed frame, a filtration space formed on the inner wall of the fixed frame, a liquid outlet formed on the inner wall of the filtration space, a first solenoid valve provided at the liquid outlet, the first solenoid valve being electrically connected to a controller fixedly mounted on the surface of the fixed frame, a liquid pump fixedly mounted on the surface of the fixed frame, the liquid pump being electrically connected to the controller, a rotating tube provided at the liquid outlet end of the liquid pump, a liquid outlet plate provided at the other end of the rotating tube, and an installation unit for rotating one end of the rotating tube to connect to the liquid outlet end of the liquid pump.
[0007] The other end of the rotating tube is connected to the surface of the liquid outlet tray. A filter bag is provided inside the filtration space. The filtration space also includes a first limiting unit and a second limiting unit. The first limiting unit is used to restrict the position of the liquid outlet tray above the filtration space. The second limiting unit is attached to the bottom of the liquid outlet tray and is used to restrict the position of the filter bag inside the filtration space.
[0008] Furthermore, the installation unit includes an adjusting tube rotatably mounted on the outlet end of the liquid pump. Several mounting bolts are threaded onto the surface of the rotating tube, and the surfaces of the mounting bolts are sequentially threaded onto the surface of the adjusting tube and the surface of the outlet plate.
[0009] Furthermore, the first limiting unit includes several rotating rods that are rotatably mounted on the surface of the fixed frame. The surface of the liquid outlet plate is provided with several through grooves. The surfaces of the several rotating rods are slidably inserted into the inner walls of the several through grooves and are all threaded with abutting nuts.
[0010] Furthermore, the second limiting unit includes a limiting groove formed in the inner wall of the filter space, a limiting disc is slidably inserted into the inner wall of the limiting groove, and one end of the filter bag is fixedly installed on the surface of the limiting disc.
[0011] Furthermore, the filter space is provided with a filter chamber inside, the surface of the filter chamber is provided with a plurality of filter holes, the surface of the filter chamber is provided with a limiting edge, and the surface of the limiting edge is slidably inserted into the inner wall of the limiting groove.
[0012] Furthermore, the surface of the fixing frame is provided with a push groove.
[0013] Furthermore, the rotating tube is equipped with a flow meter and a second solenoid valve, both of which are electrically connected to the controller.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, a filtration space is opened in the inner wall of the fixed frame. During use, the user controls the liquid pump to draw the liquid into the rotating tube through the controller. Then, the liquid enters the filtration space through the liquid outlet plate and is finally filtered by the filter bag and discharged from the outlet. After a period of use, the user can release the limit on the liquid outlet plate through the first limiting unit, and then hold the rotating tube to rotate it to move the liquid outlet plate and remove the filter bag for replacement. This design makes it convenient and quick to remove impurities and ensures the filtration effect. At the same time, during use, the liquid outlet plate is attached to the surface of the second limiting unit, which can limit the second limiting unit and ensure the stability of the filter bag during use (that is, when the high-pressure water flow impacts the surface of the filter bag, the impact force will be transmitted to the bottom of the liquid outlet plate through the second limiting unit).
[0016] 2. In this utility model, by rotating several rotating rods on the surface of the fixed frame and simultaneously opening several through grooves on the surface of the liquid outlet tray, the user can rotate several rotating rods in sequence during use, causing the surfaces of the rotating rods to slide into the inner walls of the through grooves respectively. Finally, abutment nuts are threaded onto the surfaces of several rotating rods, so that one end of each abuts against the surface of the liquid outlet tray, thus achieving a relatively stable limit on the liquid outlet tray. When it is necessary to move the liquid outlet tray later, simply rotate several abutment nuts in sequence to rotate several rotating rods and release the limit on the liquid outlet tray. This limiting method is convenient and quick, improving the efficiency of filter bag replacement. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0024] This embodiment provides an impurity filtration device for pharmaceuticals, mainly addressing the problem that while various impurity filtration devices exist, with portable mobile filtration devices being common, removing the filtered impurities is cumbersome. The following technical solution is provided in conjunction with... Figures 1-5 Please provide a detailed explanation:
[0025] A pharmaceutical impurity filtration device includes: a fixed frame 1 with a filtration space 2 on its inner wall; a liquid pump 6 fixedly mounted on the surface of the fixed frame 1; and a rotating tube 7 rotatably mounted at the outlet end of the liquid pump 6 under the action of a mounting unit 9. Therefore, during use, the user controls the liquid pump 6 via a controller 5 fixedly mounted on the surface of the fixed frame 1 to draw the pharmaceutical solution into the rotating tube 7, then into the outlet plate 8 fixedly fitted onto the surface of the rotating tube 7, and finally into the filtration space 2, thus completing the extraction of the pharmaceutical solution. Furthermore, the position of the filter bag 10 is restricted within the filtration space 2 by the action of a second limiting unit 12. Therefore, impurities inside the liquid medicine are filtered by the filter bag 10, and after filtration, they are discharged from the outlet 3 opened on the inner wall of the filtration space 2 (the outlet 3 is equipped with a first solenoid valve 4, and the controller 5 can control the conduction state of the outlet 3 by controlling the first solenoid valve 4). After filtration, the user can release the restriction on the outlet plate 8 above the filtration space 2 by using the first limiting unit 11, and then rotate the rotating tube 7 to drive the outlet plate 8 away from the top of the filtration space 2, releasing the downward pressure restriction effect of the second limiting unit 12. Finally, the filter bag 10 can be removed and replaced by using the second limiting unit 12. The main components of the installation unit 9 are: rotating... The adjusting pipe 91 installed at the outlet end of the pump 6 is used by the user to thread several mounting bolts 92 into the surface of the rotating pipe 7, so that the surfaces of the mounting bolts 92 are sequentially threaded into the surfaces of the adjusting pipe 91 and the outlet plate 8, thereby connecting the two ends of the rotating pipe 7 to the adjusting pipe 91 and the outlet plate 8 respectively. The main components of the first limiting unit 11 are several through grooves 112 all opened on the surface of the outlet plate 8. In use, the user attaches the outlet plate 8 to the surface of the fixing frame 1, and then rotates several rotating rods 111 all rotatably installed on the surface of the fixing frame 1, so that the surfaces of the several rotating rods 111 slide into the adjusting pipe 91 and the outlet plate 8 respectively. The inner walls of several through grooves 112 are connected, and finally, contact nuts 113 are threaded onto the surfaces of several rotating rods 111, so that the surfaces of several contact nuts 113 all abut against the surface of the liquid outlet plate 8, thereby limiting the liquid outlet plate 8 above the filter space 2. The main components of the second limiting unit 12 are: a limiting plate 122 fixedly installed on the top of the filter bag 10. In use, the user slides the surface of the limiting plate 122 into the inner wall of the limiting groove 121 opened in the inner wall of the filter space 2, and then limits the position of the liquid outlet plate 8 to the surface of the limiting plate 122, thereby achieving a stable limiting of the limiting plate 122 on the inner wall of the limiting groove 121.
[0026] By creating a filtration space 2 on the inner wall of the fixed frame 1, the user can control the liquid pump 6 via the controller 5 to draw the liquid into the rotating tube 7, and then through the liquid outlet plate 8 into the filtration space 2. Finally, the liquid is filtered by the filter bag 10 and discharged from the liquid outlet 3. After a period of use, the user can release the limit on the liquid outlet plate 8 via the first limiting unit 11, and then hold the rotating tube 7 to rotate it to move the liquid outlet plate 8 and remove the filter bag 10 for replacement. This design makes it convenient and quick to remove impurities and ensures the filtration effect. At the same time, during use, the liquid outlet plate 8 is attached to the surface of the second limiting unit 12, which can limit the second limiting unit 12 and ensure the stability of the filter bag 10 during use (that is, when the high-pressure water flow impacts the surface of the filter bag 10, the impact force will be transmitted to the bottom of the liquid outlet plate 8 through the second limiting unit 12).
[0027] By rotating several rotating rods 111 on the surface of the fixed frame 1, and simultaneously opening several through grooves 112 on the surface of the liquid outlet plate 8, the user can rotate several rotating rods 111 in sequence during use, causing the surfaces of the rotating rods 111 to slide into the inner walls of the through grooves 112 respectively. Finally, abutment nuts 113 are threaded onto the surfaces of several rotating rods 111, so that one end of each abutment nut 113 abuts against the surface of the liquid outlet plate 8, thus achieving a relatively stable limit on the liquid outlet plate 8. When it is necessary to move the liquid outlet plate 8 later, it is only necessary to rotate several abutment nuts 113 in sequence, which will rotate several rotating rods 111 to release the limit on the liquid outlet plate 8. This limiting method is convenient and quick, improving the efficiency of replacing the filter bag 10.
[0028] like Figure 1 As shown, in some embodiments, a filter chamber 13 is provided inside the filter space 2 (with several filter holes on the surface of the filter chamber 13). In use, the user slides the limiting edge 14 on the surface of the filter chamber 13 into the inner wall of the limiting groove 121. After the medicine enters the filter space 2, it will fall into the filter bag 10 and the filter chamber 13 in sequence, thereby achieving a more thorough filtration of the medicine. When moving this device, the user can hold the push groove 15 on the surface of the fixed frame 1 to push the fixed frame 1. Since a flow meter 16 and a second solenoid valve 17 are provided in the rotating tube 7, the user can control the second solenoid valve 17 to control the rotation of the rotating tube 7 through the controller 5 (the flow meter 16 can monitor the real-time flow, and the controller 5 can receive the data from the flow meter 16 to calculate the total flow of the medicine).
[0029] The working process of this utility model:
[0030] First, the user needs to hold the pusher 15 to push the fixed frame 1 to move, and then the external medicine liquid is introduced into the inside of the liquid pump 6. Then, the liquid pump 6 is controlled by the controller 5 to draw the medicine liquid into the inside of the filter space 2. After being filtered by the filter bag 10 and the filter chamber 13, it is discharged from the outlet 3.
[0031] Secondly, after filtration is completed, the user needs to screw on several contact nuts 113, then rotate several rotating rods 111 and rotate the rotating tube 7 to adjust the position of the liquid outlet plate 8. Finally, the filter bag 10 is taken out for cleaning and replacement, which can quickly remove impurities.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
