Specific embodiments

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with 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.

[0029] Referring to Figures 1 to 7 , the present invention provides a technical solution: a liquid preparation filtering device, including a support frame body, which is the support structure of the whole device, and its specific composition is as Figure 4 shown. The support frame body includes four supports 6 vertically arranged on the support 1. The four supports 6 form a frame structure, and the supports 6 are connected by a plurality of connection seats 7.

[0030] As Figure 1 and Figure 2 shown, a filtering device is provided on at least one side surface of the support frame body. The filtering device is in two groups and is symmetrically installed on the two side surfaces of the support frame body, which can increase the number of filtering devices and improve the filtering efficiency. The filtering device includes filters distributed in multiple layers, and the filters are detachably connected to the support frame body;

[0031] Since there are many filters distributed up and down, and the structure of each filter is the same, that is, each filter includes an installation cylinder 2. One end of the installation cylinder 2 is detachably provided with a first end cover 23, and the other end is detachably provided with a second end cover 14. The second end cover 14 and the first end cover 23 are respectively connected to the installation cylinder 2 by means of threads. Socket joints 13 are coaxially provided at the centers of the first end cover 23 and the second end cover 14 respectively;

[0032] As Figure 7As shown in the figure, in the middle of the side of the first end cover 23 close to the installation cylinder 2, a liquid passing pipe 27 communicating with the socket 13 is coaxially provided. The liquid passing pipe 27 is placed inside the end of the installation cylinder 2. The end of the liquid passing pipe 27 is sealed and there are a plurality of circulation ports 15 on its side. A limiting ring 28 is coaxially provided at one end of the liquid passing pipe 27 away from the first end cover 23. Immediately afterwards, a support plate 25 is coaxially provided at one end of the installation cylinder 2 close to the second end cover 14. There is a certain distance between the support plate 25 and the second end cover 14. An annular seat 26 is coaxially provided in the middle of the support plate 25. The annular seat 26 communicates with the support plate 25;

[0033] A filter element 24 is provided inside the installation cylinder 2. The two ends of the filter element 24 are respectively placed on the annular seat 26 and the liquid passing pipe 27, and the two ends of the filter element 24 are respectively abutted against the support plate 25 and the limiting ring 28. Sealing rings are provided on the surfaces of the support plate 25 and the limiting ring 28, which can achieve a better sealing effect;

[0034] The working process of the filter is that the external preparation flows into the liquid passing pipe 27 from the socket 13 on the first end cover 23, and then flows through each circulation port 15 into the installation cylinder 2. After passing through the outside of the filter element 24, the preparation enters the inside of the filter element 24, so that the preparation is filtered. The filtered preparation flows from the filter element 24 to the annular seat 26, and finally flows from the annular seat 26 to the second end cover 14, and finally flows out from the socket 13 located on the second end cover 14.

[0035] Based on the above embodiments, in order to facilitate the disassembly of each filter, multiple layers of first brackets 9 are provided on the side of the support frame body. Specifically, the first brackets 9 are installed on the bracket 6. There are two first brackets 9 on each layer and they are symmetrically arranged. Each first bracket 9 is provided with a groove matching the installation cylinder 2. As Figure 1 shown, each installation cylinder 2 is placed inside the first bracket 9. In order to fix the installation cylinder 2, two annular grooves 21 corresponding to the first bracket 9 are symmetrically provided on the installation cylinder 2. The first bracket 9 is placed inside the annular groove 21, so that the installation cylinder 2 is limited;

[0036] The cooperation of the annular groove 21 and the first bracket 9 can prevent the installation cylinder from moving along its axial direction. In order to prevent the installation cylinder 2 from falling out of the first bracket 9, at least one second bracket 17 is provided in the middle below the installation cylinder 2. The second bracket 17 is provided with a groove matching the installation cylinder 2. The installation cylinder 2 is placed inside the second bracket 17. A clamping seat 16 is provided above the second bracket 17. The clamping seat 16 is stuck on the installation cylinder 2. One end of the clamping seat 16 is rotatably connected to the second bracket 17, and the other end is connected to the second bracket 17 through a lock. After the clamping seat 16 is stuck on the installation cylinder 2 and locked, the installation cylinder 2 can be firmly fixed at this time.

[0037] Furthermore, as Figure 5As shown, since socket joints 13 are provided in the filter, the socket joints 13 serve to connect the external pipes, allowing the external preparations to flow into the interior of the filter. That is, a sealing sleeve 12 is sleeved on each socket joint 13, and each sealing sleeve 12 is installed on the screw linear drive device. Driven by the screw linear drive device, the sealing sleeve 12 is tightly pressed against the socket joint 13, as Figure 7 shown, the contact surface between the sealing sleeve 12 and the socket joint 13 is a conical surface. A sealing component is provided on the surface of the socket joint 13. The sealing component is a groove provided on the surface of the socket joint 13, and a sealing ring is provided in the groove;

[0038] It should be emphasized that both ends of the connecting pipe 10 are detachably installed on the pipe joints 22, and the pipe joints 22 are respectively provided on the collecting pipe 5, the liquid inlet pipe 8 and the sealing sleeve 12, which facilitates the replacement of the connecting pipe 10;

[0039] As Figure 5 and Figure 6 shown, the screw linear drive device includes L-shaped arms 4 symmetrically distributed at both ends of each mounting cylinder 2. One end of each L-shaped arm 4 is connected to the support frame body. Specifically, the L-shaped arm 4 is connected to the support 6. A transmission screw 11 coaxial with the sealing sleeve 12 is threadedly installed inside each end of the L-shaped arm 4 away from the support frame body. One end of the transmission screw 11 close to the sealing sleeve 12 is rotatably installed in the mounting seat 18, and the mounting seat 18 is coaxially connected to the sealing sleeve 12 respectively. At least one guide shaft 20 parallel to the transmission screw 11 is installed on the side of each mounting seat 18 through a support 19, and the guide shaft 20 is movably connected to the L-shaped arm 4. Specifically, the guide shaft 20 is placed in the guide seat, and the guide seat is then installed below the L-shaped arm 4;

[0040] The specific operation process is as follows. As Figure 1 and Figure 4 shown, in order to facilitate the rotation of the transmission screw 11, a handwheel 3 is installed at the end of each transmission screw 11, which facilitates the rotation of the transmission screw 11 by hand. When the transmission screw 11 is rotated, it can drive the sealing sleeve 12 to move closer to or away from the socket joint 13. Since the socket joint 13 and the sealing sleeve 12 can be in close contact, when the sealing sleeve 12 is sleeved on the socket joint 13, complete sealing can be achieved. At the same time, the transmission screw 11 can generate a certain pressure between the sealing sleeve 12 and the socket joint 13, effectively preventing the sealing sleeve 12 from loosening.

[0041] Furthermore, a connecting pipe 10 is provided at one end of each sealing sleeve 12 away from the socket joint 13. The connecting pipes 10 at both ends of the filter are respectively connected to the liquid inlet pipe 8 and the collecting pipe 5. Specifically, the liquid inlet pipe 8 and the collecting pipe 5 are installed on the connecting seat 7, so that the liquid inlet pipe 8 and the collecting pipe 5 can be fixed.

[0042] The present invention also provides a method for using a liquid preparation filtering device, which includes the following steps:

[0043] Step 1: Pass the liquid preparation into the liquid inlet pipe through an infusion pump, and connect the collection pipe to the collection device of the liquid preparation.

[0044] Step 2: Start the infusion pump to pass the liquid preparation into the liquid inlet pipe 8, so that the liquid preparation in the liquid inlet pipe 8 enters each filter, and the liquid preparation filtered by the filter is recycled through the collection pipe 5.

[0045] Step 3: When the filter needs to be replaced after being used for a preset time, only rotate the transmission screw 11 to drive the sealing sleeve 12 to separate from the socket joint 13, and then the filter can be removed.

[0046] Step 4: When installing the filter, only reinstall the new filter, and then rotate the transmission screw 11 in the reverse direction to drive the sealing sleeve 12 to tightly sleeve on the socket joint 13 again, and then filtration can be restarted.

[0047] In summary, the liquid preparation filtering device proposed by the present invention is convenient for replacing the filter, and is also convenient for installing each filter. Moreover, the number of filters is large, which can filter and produce liquid preparations for a long time and quickly.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
