Description

Technical Field

[0001] This utility model relates to the technical field of air filtration and sterilization devices, and in particular to a multi-stage air filtration and sterilization device. Background Technology

[0002] Currently, air sterilization filters are filters connected to fermentation equipment boxes. They mainly filter the air flowing out of the fermentation equipment through cotton cores installed inside the equipment. As the air moves, microorganisms in the fermentation equipment are attached to the cotton cores. During the process of adsorbing and filtering the air, moisture and fungi contained in the air are also drawn into the filter cores of the sterilization equipment. When the temperature inside the equipment drops to a level suitable for bacterial growth, the fungi intercepted in the filter cores will form colonies within the filter cores with the support of moisture, thus affecting the sterilization effect of the sterilization equipment.

[0003] The prior art CN112957884A provides a bio-fermentation air multi-stage filtration and sterilization device, the structure of which includes a sterilization device, a support, and a connecting pipe. The sterilization device is embedded and fixedly installed on the top of the support, and the support is fixedly installed on the bottom of the connecting pipe by welding. The connecting pipe is symmetrically installed on the left and right sides of the lower end of the sterilization device. The sterilization device includes a filter mechanism, a connecting pipe, and a nested shell. The nested shell is nested and installed on the outer end face of the filter mechanism, and the connecting pipe is embedded and engaged on the outer side of the lower end of the sterilization device. The nested shell is located on the top of the connecting pipe.

[0004] However, in existing technologies, the sterilization devices only filter a single number of times, and their cleaning and maintenance processes are too cumbersome. Utility Model Content

Detailed Implementation

[0017] Please see Figures 1 to 3This utility model provides a multi-stage air filtration and sterilization device, including a connecting pipe and a sterilization mechanism. The sterilization mechanism includes a first sterilization chamber 101, a second sterilization chamber 102, a filtration and sterilization assembly, a first flange 103, and a second flange 104. The first flange 103 is fixedly connected to the first sterilization chamber 101 and is fitted onto the outer wall of the first sterilization chamber 101. The second flange 104 is fixedly connected to the second sterilization chamber 102 and is fitted onto the outer wall of the second sterilization chamber 102. The first flange 103 and the second flange 104 are detachably connected by bolts. The filtration and sterilization assembly consists of multiple sets, each set of which is embedded inside the first sterilization chamber 101 and the second sterilization chamber 102. The connecting pipe is detachably connected to the first flange 103 and the second flange 104 by bolts and is located at one end of the first flange 103 and the second flange 104.

[0018] In this embodiment, the connecting pipe serves as the base for the first sterilization chamber 101 and the second sterilization chamber 102, supporting and fixing them. The first sterilization chamber 101 and the second sterilization chamber 102 are connected and fixed through the first flange 103 and the second flange 104. Multiple sets of the filter sterilization components are embedded inside the first sterilization chamber 101 and the second sterilization chamber 102 to achieve multi-stage filtration and sterilization. The first sterilization chamber 101 and the second sterilization chamber 102 are respectively connected to the connecting pipe, through which air is introduced and discharged. The multiple sets of filter sterilization components inside the first sterilization chamber 101 and the second sterilization chamber 102 achieve multiple sterilization of the air.

[0019] Furthermore, each set of the filtration and sterilization components includes an air filter element 105, an insulating support column 106, and an electric grid 107. There are multiple sets of insulating support columns 106. Each set of insulating support columns 106 is fixedly connected to the air filter element 105 and is located at one end of the air filter element 105. The electric grid 107 is fixedly connected to multiple sets of insulating support columns 106 and is located at one end of multiple sets of insulating support columns 106.

[0020] In this embodiment, the air filter element 105 filters and intercepts suspended particles and dust in the air, while the insulating support column 106 supports the electrified grid 107. The electrified grid 107 is located at one end of the air filter element 105. The incoming air is filtered by the air filter element 105 and then comes into contact with the electrified grid 107. The electrified grid 107 is energized, and a high voltage is applied to it, generating an electrostatic field around it. When bacteria, viruses, and other microorganisms, as well as dust particles, pass through the electrified grid 107 with the airflow, they are charged by the electric field and then adsorbed under the action of the electric field force. The electricity is applied to the energized grid 107 to achieve dust removal and sterilization. Under specific conditions, the energized grid 107 generates ozone. Ozone has strong oxidizing properties and can destroy the cell walls and cell membranes of bacteria and viruses, thereby killing microorganisms. When the voltage between the energized grids 107 is high enough, the generated strong electric field can break down the cell walls of bacteria, viruses and microorganisms attached to the surface of particulate matter, thus killing them. The air filter cores 105 in the multiple sets of filtration and sterilization components can have a uniform diameter or different diameters. The diameter of the air filter cores 105 can gradually decrease along the air filtration path, thereby achieving step-by-step filtration and sterilization.

[0021] Furthermore, the connecting pipe includes a connecting seat 108, a connecting flange 109, an air inlet pipe 110, and an exhaust pipe 111. The air inlet pipe 110 communicates with the connecting seat 108 and is located on the outer wall of the connecting seat 108. The exhaust pipe 111 communicates with the connecting seat 108 and is located on the outer wall of the connecting seat 108. The connecting flange 109 communicates with the connecting seat 108 and is sleeved on the outer wall of the connecting seat 108. The connecting flange 109 is compatible with the first flange 103 and the second flange 104.

[0022] In this embodiment, the air inlet pipe 110 is used to introduce air, the exhaust pipe 111 is used to discharge the filtered and sterilized air, the connecting seat 108 is used to connect the air inlet pipe 110 and the exhaust pipe 111, and the connecting flange 109 is used to connect the connecting seat 108 to the first sterilization chamber 101 and the second sterilization chamber 102.

[0023] Furthermore, the connecting pipe also includes a pressure sensor 112. There are two sets of pressure sensors 112. Each set of pressure sensors 112 is connected to the intake pipe 110 and the exhaust pipe 111 respectively, and is located on the outer wall of the intake pipe 110 and the exhaust pipe 111 respectively.

[0024] In this embodiment, by detecting the air pressure of the air intake pipe 110 and the exhaust pipe 111, the dust accumulation in the multiple sets of filter and sterilization components is determined by their air pressure ratio, thereby facilitating the determination of whether the multiple sets of filter and sterilization components can be replaced or cleaned.

[0025] Furthermore, the sterilization mechanism also includes a sealing ring 113, which is embedded between the first sterilization chamber 101 and the second sterilization chamber 102.

[0026] In this embodiment, the sealing ring 113 can improve the sealing between the first sterilization chamber 101 and the second sterilization chamber 102, and prevent gas leakage during the air filtration and sterilization process from affecting the air treatment efficiency.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
