[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0024] like Figure 1-3 As shown in some illustrative embodiments, a production device for VOC-processing bio-catalyst is provided, which fully mixes and synergistically combines microbial strains, bio-enzymes, and activated carbon to form a bio-catalyst capable of processing VOCs. The device is highly efficient, stable, reduces human intervention, and is targeted. Specifically, it includes: a housing 100, a material mixing device 200, a screening and drying device 300, and a base 400.
[0025] The housing 100 is mounted on the base 400, providing a closed operating environment for the material mixing device 200 and the screening and drying device 300. The base 400 provides support and is equipped with adjusting bolts to adjust the level of the equipment. The material mixing device 200 and the screening and drying device 300 are housed within the housing 100, with the screening and drying device 300 located on the discharge side of the material mixing device 200.
[0026] Microbial inoculum, bio-enzymes, and activated carbon are thoroughly mixed in a material mixing device 200. The resulting bio-catalyst complex then enters a sieving and drying device 300. During the drying process, smaller particles fall through the holes in the screen trays and enter the next layer of screen trays, while larger particles remain on the upper screen trays, achieving automatic sieving. This embodiment achieves rapid mixing, drying, and sieving of microbial inoculum, bio-enzymes, and activated carbon, improving production efficiency, reducing manual operation, and ensuring product quality.
[0027] The material mixing device 200 includes: a mixing container 210, a mixing outlet 220, a stirring assembly, a star-shaped discharge valve 240, a bacterial liquid inlet 250, a biological enzyme inlet 260, and an activated carbon inlet 270.
[0028] The mixing container 210 is located inside the housing 100, the screening and drying device 300 is located below the mixing container 210, the mixing outlet 220 is located at the bottom of the mixing container 210 and is the channel for the mixed material to flow to the screening and drying device 300, and the star-shaped discharge valve 240 is located inside the mixing outlet 220.
[0029] The rotary valve 240 is a commonly used material conveying control device. When closed, it provides a good seal to prevent material leakage. Simultaneously, the opening degree of the rotating blades controls the material discharge speed and output. After the mixing process of the microbial inoculum, bio-enzymes, and activated carbon is completed, the rotary valve 240 is opened. By controlling the opening and closing of the rotary valve 240, the discharge speed and output of the mixture can be precisely controlled, ensuring that the mixture enters the screening and drying device 300 uniformly and stably.
[0030] The bacterial solution inlet 250, the bio-enzyme inlet 260, and the activated carbon inlet 270 are all located on the housing 100 and are all connected to the mixing container 210. The activated carbon inlet 270 is funnel-shaped. An appropriate amount of bacterial solution containing specific microorganisms is added to the mixing container 210 through the bacterial solution inlet 250, the required bio-enzyme is added through the bio-enzyme inlet 260, and pretreated activated carbon is added through the activated carbon inlet 270. Because the activated carbon inlet 270 is funnel-shaped, the activated carbon can flow quickly and smoothly into the mixing container 210, avoiding accumulation and blockage.
[0031] Activated carbon, with its abundant porous structure and large specific surface area, can adsorb VOC molecules onto its surface through superior physical adsorption. Microorganisms and bio-enzymes can then attach to activated carbon, forming bio-catalysts capable of treating VOCs, thus combining the advantages of physical adsorption and biodegradation. Bio-catalysts can biodegrade adsorbed VOCs. Microorganisms can use VOCs as a carbon source to grow and reproduce, breaking them down into harmless substances such as carbon dioxide and water during metabolism. Bio-enzymes can accelerate the degradation reaction of VOCs through catalysis, improving degradation efficiency. Through the synergistic effect of these three factors, bio-catalysts can both rapidly adsorb VOCs to reduce pollutant concentrations and achieve complete decomposition of VOCs.
[0032] The stirring assembly includes: a motor 231, a stirring shaft 232, and a propeller blade 233.
[0033] A motor 231 is mounted on top of the mixing container 210. A stirring shaft 232 is connected to the power output end of the motor 231 and located inside the mixing container 210. A propeller blade 233 is mounted on the stirring shaft 232. When the motor 231 starts, it drives the stirring shaft 232 and the propeller blade 233 to rotate, thus slowly stirring the bacterial solution, enzymes, and activated carbon within the mixing container 210. During the stirring process, the directional stirring force generated by the propeller blade 233 causes the raw materials to circulate within the mixing container 210. After a period of stirring, all the raw materials are thoroughly and evenly mixed.
[0034] The screening and drying device 300 includes: a housing 310, a ventilation mechanism 320, a fan 330, several screen trays 340, a drain outlet 350, a drain pipe 360, and a valve 370.
[0035] The top of the housing 310 is connected to the rotary valve 240 to ensure that the mixed material can smoothly enter the screening and drying device 300 and fall onto the first layer of screen trays 340, and then fall down layer by layer to achieve screening. Slots 311 are opened on the inner wall of the housing 310. The slots 311 are used to fix and support the screen trays 340. Each screen tray 340 is arranged in sequence from top to bottom inside the housing 310.
[0036] The screen tray 340 includes a tray frame 341 and a main screen 342. The main screen 342 is disposed within the tray frame 341 and is used to hold the mixed materials while allowing air to pass through for drying. The side of the tray frame 341 has a plug 343 that fits into a slot 311; fitting means that the plug 343 can be inserted into the slot 311, allowing the screen tray 340 to be securely placed inside the machine housing.
[0037] The aperture of the upper main screen 342 is larger than that of the lower main screen 342. The mixed material enters the screening and drying device 300 through the star-shaped discharge valve 240, first contacting the uppermost main screen 342. Due to the larger aperture of the upper main screen 342, larger particles are screened out first and fall through the holes to the next layer. As the material progresses through the screen trays 340, the aperture becomes smaller, and finer particles are gradually screened out. At the bottom main screen 342, with the smallest aperture, the finest particle size can be screened.
[0038] The multi-pore screen design of the multi-layer screen tray 340 not only allows the material to be evenly distributed on the screen tray 340, increasing the contact area between the material and the air and improving the drying effect, but also plays a screening role, leaving materials of different particle sizes on the screen tray 340, providing convenience for further processing or use.
[0039] A blower 330 is located on top of the casing 310, and a ventilation mechanism 320 is connected to the blower 330. Through holes are opened on the side wall of the casing 310 at positions corresponding to the screen trays 340, and the outlet pipe of the ventilation mechanism 320 is embedded in these through holes. When the blower 330 is started, outside air is drawn into the ventilation mechanism 320. The ventilation mechanism 320 heats and dehumidifies the air to achieve suitable temperature (25-35℃) and humidity (40-60%) conditions for material drying. The treated air enters the interior of the casing 310 through the outlet pipe, making full contact with the material on the multi-layer screen trays 340, removing moisture from the material, and controlling the moisture content of the activated carbon to 10%-15%.
[0040] The ventilation system 320 includes: a dehumidifier 321, a heater 322, and a delivery pipe 323.
[0041] The dehumidifier 321 reduces the humidity in the airflow to ensure drying efficiency, while the heater 322 increases the airflow temperature to accelerate the drying process. The conveying pipe 323 transports the heated airflow to various parts of the screening and drying device. The inlet of the dehumidifier 321 is connected to the outlet of the fan 330, the inlet of the heater 322 is connected to the outlet of the dehumidifier 321, and the outlet of the heater 322 is connected to the conveying pipe 323. Several sets of outlet pipes are installed on the conveying pipe 323 to evenly distribute the hot airflow onto the screen tray 340.
[0042] The inner wall of the housing 310 has a slot 311 with a through hole above and below it, denoted as upper through hole 312 and lower through hole 313. Each set of air outlet ducts consists of a first air guide duct 324 and a second air guide duct 325. The first air guide duct 324 is embedded in the upper through hole 312 to guide the hot airflow to the top of the screen tray 340, and the second air guide duct 325 is embedded in the lower through hole 313 to guide the hot airflow to the bottom of the screen tray 340. This design ensures that the hot airflow can be blown evenly across the screen tray 340 from two different directions, thereby improving drying efficiency. It also ensures uniform drying of the material during the screening process. The airflow in both the upper and lower directions effectively prevents the material from accumulating on the screen, improving the drying effect.
[0043] Larger particles are screened onto higher screen trays 340. As the material decreases with each layer of screen trays 340, the diameter of the screened particles becomes smaller and smaller. In this embodiment, the higher screen trays 340 are closer to the fan 330, resulting in a higher temperature and faster flow rate of the hot air entering the first layer of screen trays 340, which is more suitable for drying larger particles. As the hot air flows through the conveying pipe 323, the temperature and pressure gradually decrease, making it more suitable for drying smaller particles. The structural design of this embodiment allows for targeted control of the wind speed and temperature at each screen tray 340, adapting to the drying needs of different layers of bio-catalysts, thereby ensuring product quality.
[0044] A drain port 350 is located at the bottom of the casing 310. One end of a drain pipe 360 is connected to the drain port 350, and the other end passes through the housing 100 and is equipped with a valve 370. As the drying process proceeds, moisture in the material evaporates, and some of the moisture collects at the bottom of the casing 310 under gravity. Opening the valve 370 of the drain port 350 discharges the collected moisture outside the equipment, preventing moisture from accumulating inside the casing 310 and affecting the drying effect.
[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
