Description

Technical Field

[0001] This utility model belongs to the field of disinfectant processing technology, specifically referring to a composite filtration device for disinfectant processing. Background Technology

[0002] Disinfectants are chemical agents used to eliminate pathogenic microorganisms (bacteria, viruses, fungi, etc.) in the environment. They achieve the purpose of "cutting off the transmission route and preventing infection" by destroying the cell structure, enzyme system, or genetic material of microorganisms. Filtration is a key purification step in the production of disinfectants. Its core purpose is to remove impurities, which may come from raw materials, the production process, or equipment. If these impurities are not removed, they will directly affect the quality, safety, and effectiveness of the disinfectant.

[0003] Existing disinfectant filtration devices separate unfiltered and filtered disinfectant using filter plates, but the fixed size of the filter pores makes adjustment inconvenient. The filter plates trap suspended and deposited particles from the disinfectant, causing blockage of the filter pores and affecting the filtration efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a composite filtration device for disinfectant processing, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: A composite filtration device for disinfectant processing is proposed, including at least two filtration sections. Each filtration section includes a first filter cylinder and a second filter cylinder arranged in a stacked manner, with the first filter cylinder sleeved outside the second filter cylinder. The filter holes of the first filter cylinder and the second filter cylinder overlap to form a filtration area. A collection section includes a collecting base disposed at the bottom of the outside of the first filter cylinder. The collecting base has an annular collecting cavity inside, which gradually narrows from the bottom to the top. The filtration section is configured to allow relative rotation between the first filter cylinder and the second filter cylinder to adjust the pore size of the filtration area. A conical guide is provided at the bottom of the inside of the second filter cylinder. The inside of the collecting cavity and the inside of the second filter cylinder are connected through the pores on the edge of the guide.

[0006] Furthermore, a barrel shell is fitted around the outside of the first filter cartridge, and there is a gap between the inner wall of the barrel shell and the outer wall of the first filter cartridge.

[0007] Furthermore, the upper outer end of the first filter cartridge is fixedly connected to the inner wall of the barrel shell by a connecting ring, the top of the first filter cartridge is fixedly connected to a feed pipe, and the bottom outer end of the barrel shell is fixedly connected to a discharge pipe.

[0008] Furthermore, the feed pipes are connected by a splitter pipe, and the splitter pipe is equipped with a valve body that adjusts the liquid flow to any of the feed pipes.

[0009] Furthermore, the other end of the discharge pipe connected to the barrel shell is rotatably connected to a connector.

[0010] Furthermore, a limiting protrusion is provided in several filter holes of the second filter cartridge, and the limiting protrusion slides within the filter holes of the first filter cartridge. Beneficial effects

[0011] The filtration area formed by the overlapping of the first and second filter cartridges can be adjusted as the two cartridges rotate relative to each other, allowing for the discharge of filtration sections arranged in descending order of filtration area size. The filtration area can also be adjusted to a specified size to filter the disinfectant. A guide at the bottom of the second filter cartridge guides impurities inside the disinfectant towards the edge, and the collection chamber in the collecting base collects the deposited impurities.

[0014] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0016] As mentioned earlier, existing disinfectant filtration devices separate unfiltered and filtered disinfectant through filter plates, but the fixed size of the filter pores makes adjustment inconvenient. Due to the filter plate's interception, suspended solids and sediments in the disinfectant mix together, easily causing clogging of the filter pores and affecting the disinfectant's filtration efficiency.

[0017] To address this issue, this utility model provides a composite filtration device for disinfectant processing. It utilizes the stacking of a first filter cartridge 101 and a second filter cartridge 102. The filtration area 3 formed by the overlapping filter holes of the two cartridges can be adjusted as the two cartridges rotate relative to each other. This allows for the discharge of the filter section 1, with the filtration areas 3 arranged in descending order of size to filter the disinfectant. A guide 4 at the bottom of the second filter cartridge 102 guides impurities inside the disinfectant towards the edge, and the collection chamber 202 in the collecting base 201 collects the deposited impurities. At least two filter sections 1 can be used interchangeably, facilitating the replacement, disassembly, and maintenance of one of the filter sections 1. The descending arrangement of the filtration areas 3 effectively reduces clogging and improves filtration efficiency.

[0018] like Figures 1-6 As shown in the figure, this utility model provides a composite filtration device, particularly a composite filtration device for disinfectant processing, including at least two filtration sections 1, a collection section 2, a filtration area 3, a guide member 4, and a shell 5. The filtration section 1 includes two first filter cylinders 101 and second filter cylinders 102 stacked together. The first filter cylinder 101 is fitted over the second filter cylinder 102, and the outer wall of the second filter cylinder 102 is in close contact with the inner wall of the first filter cylinder 101. The filter holes of the two filter cylinders are distributed identically and can overlap each other. The overlapping filter holes of the two filter cylinders form the filtration area 3 of the filtration section 1. Because the two filter cylinders are stacked and can rotate relative to each other, the size of the filtration area 3 formed by the overlapping filter holes can be adjusted.

[0019] A conical guide 4 is provided at the bottom of the second filter cartridge 102. The bottom edge of the guide 4 is open at both ends, facilitating the downward leakage of the liquid to be filtered inside the second filter cartridge 102. The top of the guide 4 slopes towards the edge, guiding impurities deposited at the bottom of the second filter cartridge 102 towards the edge, and then leaking downward through the leakage holes at the bottom edge of the guide 4. A collecting base 201 is detachably provided at the bottom outer end of the first filter cartridge 101 via a nut. The collecting base 201 is composed of two half-shells joined together, and an annular collecting cavity 202 is formed at the bottom inner end of the collecting base 201. Figure 3 As shown, the opening formed on the inner wall of the collection chamber 202 is narrower at the top but wider at the bottom, which can effectively reduce the impact caused by the new disinfectant entering the interior of the second filter cartridge 102 and flush out the impurities collected inside the collection chamber 202.

[0020] A casing 5 is fitted over the two stacked filter cartridges. There is a space between the inner wall of the casing 5 and the outer wall of the first filter cartridge 101 for temporary storage of the filtered disinfectant. Figure 1 As shown, taking two sets of filter sections 1 as an example, the two barrel shells 5 need to be assembled into one set. The outer top of the first filter cylinder 101 is fixedly connected to the inner wall of the barrel shell 5 by a connecting ring 6, while the top of the inner second filter cylinder 102 extends upward through a conical inner shell and fits tightly against the inner wall of the barrel shell 5. A feed pipe 7 extends from the top of the barrel shell 5, and the feed pipe 7 is connected to the interior of the second filter cylinder 102. At the bottom of the barrel shell 5, an inverted conical half-shell is connected by bolts, and this half-shell is connected to a discharge pipe 8. The discharge pipe 8 and the feed pipe 7 are connected to different shells, so the barrel shell 5 can rotate relative to the second filter cylinder 102 to adjust the pore size of the filtration area 3.

[0021] The feed pipe 7 is connected to the distribution fork pipe 9. A valve body 10 is installed on the distribution fork pipe 9 to control which filter section 1 the disinfectant to be filtered flows into, so that one filter section 1 is used while the other is not, facilitating timely cleaning of the filter cartridge. A limiting protrusion 12 is installed inside a portion of the filter holes of the second filter cartridge 102. The other end of the limiting protrusion 12 extends into the filter holes of the first filter cartridge 101. The limiting protrusion 12 limits the rotation between the two filter cartridges by limiting the filter holes of the two filter cartridges from complete overlap to partial overlap. A connector 11 is installed at the end of each discharge pipe 8, which connects to other pipes, allowing rotation between the shell 5 and the second filter cartridge 102. All rotating connections are sealed.

[0022] When using this filtration device, the casing 5 is placed vertically with the inlet pipe 7 facing upwards and the outlet pipe 8 facing downwards. Unfiltered disinfectant is injected into the inlet pipe 7. Impurities inside the disinfectant are guided by the inclined surface on the guide 4, and fall into the collection chamber 202 of the collecting base 201 through the holes at the bottom edge of the guide 4. The shape of the collection chamber 202 is narrower at the top and wider at the bottom to prevent the disinfectant from entering the interior of the second filter cartridge 102 and flushing out the impurities inside the collection chamber 202. After being filtered by the filtration area 3 formed by the overlapping part of the filter holes of the two filter cartridges, the filtered disinfectant flows between the first filter cartridge 101 and the casing 5, and is discharged outwards from the outlet pipe 8. By rotating the casing 5, the size of the filtration areas 3 can be arranged in descending order to filter the disinfectant step by step, which can effectively reduce the occurrence of clogging during filtration.

[0023] In summary, this invention, through the nesting of the first filter cartridge 101 and the second filter cartridge 102, utilizes the adjustable filtration area 3 formed by the overlapping portion of the filter holes of the two filter cartridges, which can be adjusted as the two filter cartridges rotate relative to each other. This allows for the discharge of the filter section 1, with the filtration areas 3 arranged in descending order of size to filter the disinfectant. The guide 4 at the bottom of the second filter cartridge 102 guides impurities inside the disinfectant towards the edge, and the collection chamber 202 in the collecting base 201 collects the deposited impurities.

In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
