Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an improved filter. Background Technology

[0002] A filter is a device or equipment used to separate and remove impurities, particles, contaminants, etc., from a fluid. A water-for-injection filter is a device or equipment used to filter water for injection. It utilizes the pore size of the filter medium (such as a microporous membrane or filter cartridge) to block and retain impurities, microorganisms, pyrogens, and other harmful substances in the water for injection, purifying the water to meet the quality standards for water for injection. Currently, filters need to be imported, resulting in long purchase cycles and high prices, causing significant inconvenience to production. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model provides a technical solution: an improved filter, comprising: a mounting frame 1, a mounting plate 2 mounted on the top of the surface of the mounting frame 1, a mounting plate 3 mounted on the bottom of the surface of the mounting frame 1, filters 4 mounted at equal intervals on the surface of the mounting plate 2, filters 5 mounted at equal intervals on the surface of the mounting plate 3, filters 4 and filters 5 connected by a pipe 6, an inlet pipe 7 mounted on the bottom of the mounting frame 1, an outlet pipe 8 mounted on the top of the mounting frame 1, filters 5 and the inlet pipe 7 connected by a pipe 9, filters 4 and the outlet pipe 8 connected by a pipe 9, and a stabilizing plate 10 mounted on the surface of the mounting frame 1.

[0025] Specifically: When the device is first put into use, water from the inlet pipe 7 enters each filter 5 through pipe 29 and is filtered by filter 25. The filter material inside filter 25 is polypropylene, which can filter large particulate impurities in the water, such as silt and rust. The filtered water then enters filter 4 through pipe 16 for further filtration. The filter material inside filter 4 is hollow fiber bundles. Water enters filter 4 through pipe 16 and flows from bottom to top, passing through the micropores of the hollow fiber membrane into the fiber interior, while impurities, bacteria, viruses, etc. are trapped outside the membrane, thus achieving water filtration and purification. Then, the water is discharged through pipe 29 into the outlet pipe 8. The use of filter 4 makes the device more affordable, simplifies the purchase of spare parts, and more effectively improves the quality of water for injection, making the device more complete.

[0026] In one embodiment, mounting shells 201 are installed at equal intervals on the surface of mounting plate 2, friction plates 202 are installed on the inner wall of mounting shell 201, the surface of filter 4 is embedded in the inner wall of mounting shell 201, mounting shells 301 are installed at equal intervals on the surface of mounting plate 3, friction plates 302 are installed on the inner wall of mounting shell 301, and the surface of filter 5 is embedded in the inner wall of mounting shell 301.

[0027] Specifically: Multiple mounting shells 201, equidistantly mounted on the surface of mounting plate 2, are used to mount filter 4. Friction plates 202 mounted on the inner wall of mounting shell 201 increase the friction of filter 4 inside the mounting shell 201, preventing it from falling off. Multiple mounting shells 301, equidistantly mounted on the surface of mounting plate 3, are used to mount filter 5. Friction plates 302 mounted on the inner wall of mounting shell 301 increase the friction of filter 5 inside the mounting shell 301, preventing it from falling off, thus making the device more complete.

[0028] In one embodiment, bolts 11 are threaded into both ends of the stabilizing plate 10, and the surface threads of the bolts 11 are embedded inside the mounting bracket 1. Grooves 12 are equally spaced on one side of the stabilizing plate 10, and the inner wall of the grooves 12 is fitted onto the surface of the pipe 6.

[0029] Specifically: The bolts 11 threaded at both ends of the stabilizing plate 10 are threaded into the inside of the mounting frame 1, so that the stabilizing plate 10 is installed on the mounting frame 1. The surface of the pipe 6 is embedded in the grooves 12 that are equally spaced on one side of the stabilizing plate 10, so that the pipe 6 connecting the filter 4 and the filter 5 is restricted, so that the pipe 6 can be more neat and the device is more perfect.

[0030] In one embodiment, connector 13 is installed at both ends of filter 4 and filter 5, connector 24 is installed at both ends of pipe 6, and connector 315 is installed at one end of bolt 11.

[0031] Specifically: After installing filters 4 and 5 on the device, connect filters 4 and 5 together by screwing connector 14 (installed at one end of pipe 6) onto connector 13 (installed at one end of filter 4) and the other end onto connector 13 (installed at one end of filter 5). Install the other end of pipe 9 onto inlet pipe 7, screw connector 315 (installed at one end of pipe 9) onto connector 13 (installed at the other end of filter 5), and install the other end of pipe 9 onto outlet pipe 8. Screw connector 315 (installed at one end of pipe 9) onto connector 13 (installed at the other end of filter 4). By unscrewing all connectors 14 and 315, filters 4 and 5 can be removed and replaced, making the device more complete.

[0032] In one embodiment, a pressure regulating valve 16 is installed on the surface of the water inlet pipe 7, a pressure gauge 17 is installed on the surface of the water inlet pipe 7, and a flow meter 18 is installed on the surface of the water inlet pipe 7.

[0033] Specifically: The water pressure can be controlled by rotating the pressure regulating valve 16 installed on the surface of the water inlet pipe 7, the water pressure can be seen through the pressure gauge 17, and the flow rate can be seen through the flow meter 18, making the device more complete.

[0034] Working Principle: When the device is first used, the water pressure can be controlled by rotating the pressure regulating valve 16 installed on the surface of the inlet pipe 7. The water pressure can be viewed through the pressure gauge 17. The water inside the inlet pipe 7 enters the interior of each filter 5 through pipe 2 9 and is filtered by the filter material inside filter 2 5. The filter material inside filter 2 5 is polypropylene, which can filter large particles of impurities in the water, such as silt and rust. The filtered water then enters the interior of filter 4 through pipe 1 6 for further filtration. The filter material inside filter 4 is hollow fiber bundles. Water enters the interior of filter 4 through pipe 1 6 and flows from bottom to top, passing through the micropores of the hollow fiber membrane into the fiber interior. Impurities, bacteria, and viruses are trapped outside the membrane, thus achieving water filtration and purification. The water is then discharged through pipe 29 into the interior of outlet pipe 8. The use of filter 4 makes the device more affordable, simplifies spare parts procurement, and effectively improves the quality of water for injection, making the device more complete. The surface threads of bolts 11, which are threaded at both ends of the stabilizing plate 10, are embedded inside the mounting bracket 1, allowing the stabilizing plate 10 to be installed on the mounting bracket 1. The surface of pipe 6 is embedded in the grooves 12 that are equally spaced on one side of the stabilizing plate 10, restricting the pipe 6 that connects filter 4 and filter 25, making pipe 6 neater and the device more complete.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
