Description

Technical Field

[0001] This utility model relates to a material handling device, specifically to a technology that can uniformly spray microbial agents in a vacuum environment. Background Technology

[0002] Based on the porous characteristics of coal gangue, fly ash and other coal-based solid wastes after being crushed and granulated, it is planned to be used as a soil structure improver, which can prevent soil compaction, store moisture and provide a living environment for microorganisms.

[0003] For example, prior art patent document CN202311187218.8 discloses a method for preparing artificial soil mainly composed of coal gangue. In addition, prior art CN202311430660.9 also discloses a method for preparing a soil conditioner containing coal gangue.

[0004] In the preparation of this type of artificial soil, adding suitable microorganisms is a crucial step. Microorganisms play a vital role in the input and output of matter and energy in soil, activating organic and inorganic nutrients, decomposing organic matter, releasing nutrients, and increasing nutrient availability. However, in existing technologies, when adding microbial agents to this coal-based artificial soil, it is usually done by simple spraying, resulting in a slow dispersion rate of the microorganisms into the soil. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, thereby providing a technology that facilitates the provision of a vacuum environment and the spraying of microbial agents.

[0006] To achieve the above objectives, this utility model provides a vacuum material microbial agent physical reaction device, which includes a material reaction chamber, an air inlet assembly, a material nozzle, and a vacuum pump; the material reaction chamber has a top cover; the air inlet assembly has an air inlet valve, a portion of which is inserted into the material reaction chamber; the material nozzle is located below the center of the top cover and is used to spray liquid into the material reaction chamber;

[0007] A vacuum pump is connected to the material reaction chamber via a connecting pipe, and an air filter is installed on the connecting pipe.

[0008] Preferably, a material tilting drum is located at the bottom of the material reaction chamber. The design of the material tilting drum ensures that the material is constantly rotating, thereby achieving more thorough mixing with the microorganisms.

[0009] Preferably, the air filter uses a 0.22µm filter element to filter particulate matter in the air. This serves to filter particulate matter in the air and protect the equipment.

[0010] Preferably, the inner wall of the material reaction chamber has a ceramic coating or a Teflon coating. This coating is heat-resistant, easy to clean, and prevents residue buildup, making it very convenient to use.

[0011] Preferably, the vacuum pump has a control panel, which includes a switch, an indicator light, a pressure adjustment knob, and a vacuum pressure gauge. The switch is used to start and stop the vacuum pump, the indicator light is used to indicate the start / stop status, the pressure adjustment knob is used to adjust the power of the vacuum pump, and the vacuum pressure gauge is used to monitor the air pressure.

[0012] Preferably, the material nozzle sprays out a microbial agent.

[0013] Preferably, when the porosity of the material in the material reaction chamber is >35%, the material nozzle is selected from DN50 large-diameter valves, and the flow rate of the DN50 large-diameter valve is ≥300L / min.

[0014] Preferably, when the viscosity of the microbial agent is >500 cP, a heating layer is provided in the interlayer of the material reaction chamber.

[0015] Preferably, the system further includes an isolation assembly, which includes a drive motor, a rotating lead screw, a fixed slide rod, a lifting block, a protective isolation plate cover, and a rotating motor. The drive motor is connected to the rotating lead screw, which is arranged parallel to the fixed slide rod. The lifting block cooperates with the rotating lead screw and is slidably cooperates with the fixed slide rod. The rotating motor is mounted on the lifting block and is connected to the protective isolation plate cover.

[0016] The beneficial effects of this invention are as follows: Coal gangue, fly ash, and other coal-based solid waste powders are placed in the material reaction chamber, and then microbial agents are sprayed through a material nozzle at the top center. These microorganisms can evenly adhere to the surface of the material. Furthermore, a vacuum environment is provided by a vacuum pump to allow the microbial agents to enter the porous material more quickly. During operation, the gas valve must be closed, and at the end of the reaction, the gas valve must be opened to restore atmospheric pressure.

[0017] The principle that adding microbial agents requires a vacuum environment:

[0018] (1) Enhanced pore permeation: The vacuum pump removes air from the pores of the material through negative pressure, which significantly reduces gas resistance. According to Darcy's law, the permeation rate of a fluid in a porous medium is proportional to the pressure gradient. A vacuum environment can establish a pressure difference of 10^3-10^4 Pa, which increases the permeation rate of the bacterial solution by 3-5 times.

[0019] (2) Oxygen environment regulation: For facultative / obligatory anaerobic bacteria (such as Bacillus mucilaginosus), a vacuum environment can reduce the oxygen partial pressure to <5 kPa, which is more in line with their optimal metabolic conditions. Experimental data show that the ATP synthesis efficiency of bacteria can be increased by 40-60% under these conditions.

[0020] (3) Dispersion and homogenization: The microbubble bursting effect generated by vacuum (when the pressure drops suddenly, the bubble radius R and the pressure P satisfy the relationship PV=nRT) can break the bacterial agent agglomerates. Laser particle size analysis shows that the particle size distribution D50 can be reduced from 50μm to below 10μm. Attached Figure Description

[0037] Preferably, the inner wall of the material reaction chamber 1 has a ceramic coating or a Teflon coating. This coating is heat-resistant, easy to clean, and prevents residue buildup, making it very convenient to use.

[0038] Preferably, the vacuum pump 4 has a control panel 42, which has a switch 421, an indicator light 422, a pressure adjustment knob 423, and a vacuum pressure gauge 424.

[0039] Preferably, the material nozzle 3 sprays out a microbial agent.

[0041] Preferably, when the viscosity of the bacterial agent is >500 cP, a heating layer is provided in the interlayer of the material reaction chamber 1.

[0042] The beneficial effects of this invention are as follows: Coal gangue, fly ash, and other coal-based solid waste powders are placed in the material reaction chamber, and then microbial agents are sprayed through a material nozzle at the top center. These microorganisms can evenly adhere to the surface of the material. Furthermore, a vacuum environment is provided by a vacuum pump to allow the microbial agents to enter the porous material more quickly. During operation, the gas valve must be closed, and at the end of the reaction, the gas valve must be opened to restore atmospheric pressure.

[0043] The principle that adding microbial agents requires a vacuum environment:

[0044] (1) Enhanced pore permeation: The vacuum pump removes air from the pores of the material through negative pressure, which significantly reduces gas resistance. According to Darcy's law, the permeation rate of a fluid in a porous medium is proportional to the pressure gradient. A vacuum environment can establish a pressure difference of 10^3-10^4 Pa, which increases the permeation rate of the bacterial solution by 3-5 times.

[0045] (2) Oxygen environment regulation: For facultative / obligatory anaerobic bacteria (such as Bacillus mucilaginosus), a vacuum environment can reduce the oxygen partial pressure to <5 kPa, which is more in line with their optimal metabolic conditions. Experimental data show that the ATP synthesis efficiency of bacteria can be increased by 40-60% under these conditions.

[0046] (3) Dispersion and homogenization: The microbubble bursting effect generated by vacuum (when the pressure drops suddenly, the bubble radius R and the pressure P satisfy the relationship PV=nRT) can break the bacterial agent agglomerates. Laser particle size analysis shows that the particle size distribution D50 can be reduced from 50μm to below 10μm.

The drive motor 51 is connected to the rotating lead screw 52, ​​and the rotating lead screw 52 is arranged parallel to the fixed slide rod 53. The lifting block 54 cooperates with the rotating lead screw 52, ​​and the lifting block 54 is slidably cooperates with the fixed slide rod 53. The rotating motor 56 is mounted on the lifting block 54 and is connected to the protective isolation plate cover 55.

[0049] During the mixing process, in order to prevent coal dust from adhering to the nozzle and causing blockage, an isolation plate cover 55 is installed here. When it is necessary to close and protect the material nozzle, it is lowered below the material nozzle, and the isolation plate cover 55 is rotated to the bottom of the material nozzle by rotating the motor. Then, by adjusting the height, the isolation plate cover 55 is placed under the material nozzle to play a protective and isolation role and prevent coal dust from clogging the material nozzle.

[0051] Typical representatives: Arbuscular mycorrhizal fungi (AMF), Trichoderma harzianum and Bacillus mucilaginosus. (2) Functional subdivision: AMF: increases phosphorus absorption efficiency by 300% by forming a hyphal network (hyphal length density can reach 20 m / cm³). Trichoderma harzianum: secretes chitinase (activity > 50 U / mL) to prevent soil-borne diseases. Bacillus mucilaginosus: produces organic acids (oxalic acid / citric acid concentration up to 15 mM) to dissolve mineral potassium. (3) Other common species: including nitrogen-fixing bacteria (such as Azospirillum brasiliensis, nitrogenase activity ≥ 200 nmol C2H4 / mg protein / h), photosynthetic bacteria (such as Rhodopseudomonas palustris, chlorophyll synthesis up to 5 mg / g DCW), etc. The specific selection needs to be adapted according to the target material pH (recommended range 5.5-8.0) and C / N ratio (optimal 25-30).
