Description

Technical Field

[0001] This utility model relates to a microbial propagation device, and more particularly to an incubation and propagation device suitable for use with environmental microorganisms, belonging to the field of environmental protection equipment technology. Background Technology

[0002] In the fields of industrial wastewater treatment and ecological restoration of rivers, lakes, and landscape water, microorganisms are increasingly being used for pollution control. However, due to the large demand for microorganisms (i.e., strains) in the treatment process, purchasing finished strains directly from the market is often costly. Furthermore, due to the tight timeframes required for the restoration of certain systems, it is not feasible to purchase or produce large quantities of microbial agents. Therefore, using biogenerators to expand and cultivate strains on-site has become an effective method to reduce water treatment costs and facilitate emergency system restoration.

[0003] Existing biological agent propagation devices are usually quite simple in structure. The large bubbles generated by the oxygen supply mean that most of the oxygen in the bubbles is not provided to the inoculum. In addition, due to the relatively simple stirring method, the inoculum raw material generates vortices in the same direction as the stirring blades, which reduces the stirring effect of the inoculum raw material and also reduces the contact rate between the inoculum raw material and oxygen, resulting in an incomplete propagation process. Utility Model Content

[0004] This invention addresses the shortcomings of existing biological agent propagation devices by providing a microbial propagation device with diversified stirring methods and improved efficiency of contact between the bacterial raw materials and oxygen.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A microbial culture device includes a box, the interior of which is divided into an equipment area, a culture area and a drug dissolution area, the equipment area and the culture area are separated by a partition, and the culture area and the drug dissolution area are connected.

[0007] The expansion zone is fixed at the top with a first vertical mixer. Multiple rotating blades are evenly distributed on the downward-extending mixing shaft of the first vertical mixer. The top of the expansion zone is also provided with a feeding hole, an inspection hole, and an exhaust hole. An exhaust solenoid valve is provided at the exhaust hole. A pH sensor, a DO sensor, a liquid level sensor, and a temperature sensor are respectively provided in the middle part of the expansion zone. Multiple swirling aeration discs are provided at the bottom of the expansion zone. The swirling aeration discs are connected to the aeration riser through pipelines.

[0008] A second vertical mixer is fixed at the top of the drug dissolving zone. Multiple rotating blades are evenly distributed on the downward-extending stirring shaft of the second vertical mixer. At the same time, a drug addition hole is also provided at the top of the drug dissolving zone.

[0009] The equipment area is equipped with an electromagnetic air pump, a dosing metering pump and a control module. The electromagnetic air pump is connected to the aeration riser through a pipeline, and the dosing metering pump is connected to the dosing hole through a pipeline.

[0010] Both the expansion zone and the dissolving zone are equipped with overflow pipes at the top that communicate with the outside, and discharge pipes at the bottom, with discharge solenoid valves installed on the discharge pipes.

[0011] The first vertical mixer, the second vertical mixer, the exhaust solenoid valve, the pH sensor, the DO sensor, the liquid level sensor, the temperature sensor, the dosing metering pump, the electromagnetic air pump, and the discharge solenoid valve are all connected to the control module.

[0012] The beneficial effects of this utility model are:

[0013] (1) This device uses a swirling aeration method for aeration. The airflow is cut in multiple layers by a spiral cutting system, which cuts the bubbles into microbubbles. This makes the aeration uniform and the oxygenation efficiency high, which greatly improves the utilization rate of oxygen and allows oxygen to fully promote the metabolism and growth of the bacteria.

[0014] (2) This device adopts a mixing method that combines swirling aeration with vertical mixer. The upward flow generated by aeration in the expansion zone and the vortex generated by the rotation direction of the rotating blades are combined to form a relatively disordered liquid turbulence, which allows the strain to fully contact dissolved oxygen and greatly improves the efficiency of strain expansion.

[0015] Furthermore, a solar power supply module is installed above the expansion cultivation area.

[0016] Preferably, the solar power supply module includes a bracket, a solar panel, and a solar controller. The solar panel is installed at an angle on the bracket, the solar controller is electrically connected to the solar panel, and the solar controller is communicatively connected to the control module.

[0017] The beneficial effects of adopting the above-mentioned further technical solution are that the solar power panel is used to convert solar energy into electrical energy to power the various electrical devices of the microbial culture device, and the solar controller is used to control the operation of the solar power panel, so that the various electrical devices of the microbial culture device of this utility model can be used normally without being connected to the mains power and are not limited by the site, which is energy-saving, environmentally friendly and has low investment and operating costs.

[0018] Furthermore, temperature-regulating jackets are provided on the outer walls of the expansion zone and the dissolution zone.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that when the temperature at the application site is too low or too high and does not meet the suitable temperature required for the propagation of the strain, fluid can be conveniently introduced into the temperature control jacket to adjust the actual operating temperature of the propagation zone in order to achieve the best propagation effect.

[0020] Furthermore, a cleaning module is provided at the top of the expansion zone and the dissolving zone. The cleaning module includes a water supply hose, an annular pipe and multiple nozzles. The annular pipe is fixed to the inner wall of the top of the expansion zone and the dissolving zone. The water inlet end of the annular pipe is connected to the water supply hose, and the nozzles are evenly distributed on the annular pipe.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that after the expansion device is used up, it can be connected to an external water pump through a water supply hose, and cleaning water or cleaning agent can be sprayed into the expansion area and the dissolving area through the nozzle on the annular pipe to clean the device, which is convenient for subsequent use.

[0022] Furthermore, the expansion zone and the drug dissolving zone are equipped with ultraviolet disinfection lamps.

[0023] The beneficial effect of adopting the above-mentioned further technical solution is that, before and after the use of the expansion device, ultraviolet disinfection lamps can be used to sterilize and disinfect the expansion area and the drug dissolving area, so as to avoid contamination by miscellaneous bacteria and affect the effect of strain expansion.
