Description

Technical Field

[0001] The invention relates to the technical field of river pollution control equipment, and in particular to a microbial agent expansion and addition device for river pollution control. Background Art

[0002] As an important carrier of water resources, the quality of river water is directly related to ecological balance and human health. Among the many pollution control methods, bioremediation technology has attracted widespread attention due to its advantages of environmental protection, high efficiency and low cost. Among them, the application of microbial agents is an important direction in bioremediation technology.

[0003] Existing microbial inoculants usually need to be propagated in onshore laboratories or specific propagation facilities. These facilities provide controlled temperature, nutrient content and other conditions to ensure that the microorganisms can multiply rapidly and reach the required concentration. However, this process has some obvious limitations. First, since the propagation is completed at a fixed location, when the inoculants need to be placed in rivers at different locations, a large amount of propagated inoculants must be manually transported from land to ships. This process not only increases transportation costs, but may also reduce the activity of the inoculants due to improper handling, affecting the treatment effect.

[0004] Secondly, the actual dosing process is also highly dependent on manual operation. Specifically, the staff needs to first move the container of the bacterial agent onto the ship, and then slowly sail to the target waters according to the pre-set dosing point. After arriving at the designated location, workers need to evenly disperse the bacterial agent into the water by manual sprinkling or simple pouring. For large-scale river management projects, such a huge workload makes it difficult to ensure that the dosage is accurate each time, which may lead to insufficient management in some areas and excessive dosing in other areas, thus affecting the overall pollution control efficiency and effectiveness.

[0005] To this end, the present application specifically proposes a device for expanding and adding microbial agents for river pollution control to solve the above-mentioned technical problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0031] like Figure 1-9 As shown, the present invention provides a device for expanding and adding microbial agents for river pollution control, comprising:

[0032] A power hull 1, with a portable generator 2 arranged in the cabin;

[0033] The expansion and cultivation tank body 3 is arranged in the cabin of the power hull 1, and includes an expansion and cultivation inner tank 31, an insulation outer tank 32 sleeved on the outside of the expansion and cultivation inner tank 31, a water bath cavity 33 arranged between the expansion and cultivation inner tank 31 and the insulation outer tank 32, an upper cover 34 arranged on the top of the expansion and cultivation inner tank 31, and a feed hopper 35 for adding microbial agents and nutrient bases to the expansion and cultivation inner tank 31, and the feed hopper 35 is equipped with a plugging cover 36;

[0034] The water inlet filter assembly 4 is arranged on the outer wall of the heat-insulating outer tank 32 and one end of the water extends into the river channel and the other end is connected to the expansion tank 31, and is used to extract water from the river channel and inject it into the expansion tank 31 after filtering;

[0035] The jet dosing assembly 5 includes a liquid outlet valve pipeline 51 connected to the bottom of the expansion tank 31, a metering diaphragm pump 52 whose liquid inlet is connected to the liquid outlet valve pipeline 51, and a jet tube assembly 53 fixedly arranged on the power hull 1 and connected to the liquid outlet of the metering diaphragm pump 52. The metering diaphragm pump 52 is electrically connected to the portable generator 2.

[0036] Before use, the microbial agent and the nutrient medium are first poured from the feed hopper 35 into the inner tank 31 for expansion and cultivation, and then the water in the river is extracted by the water inlet filter assembly 4, and the water is filtered to remove the miscellaneous bacteria, viruses, etc., and then injected into the inner tank 31 for expansion and cultivation to provide a clean liquid environment for the expansion and cultivation of the microbial agent. After the appropriate amount of water is injected, the mixture in the inner tank 31 for expansion and cultivation is stirred to make the microbial agent and the nutrient medium evenly mixed in the water body, and the expansion and cultivation can be carried out after the plugging cover 36 is covered. After the expansion and cultivation is completed, the liquid outlet valve pipeline 51 is opened, and the metering diaphragm pump 52 is started, and the pumping rate of the metering diaphragm pump 52 is adjusted as needed. The metering diaphragm pump 52 pumps the microbial agent after expansion and cultivation into the jet tube assembly 53 and further injects it into the water body of the river, completing the addition of the microbial agent, and the portable generator 2 supplies power to the metering diaphragm pump 52 and the electrical appliances in the water inlet filter assembly 4. The device realizes the direct expansion and cultivation of microbial agents on the power hull 1, reducing the transportation cost of the agents, and utilizes the jet dosing component 5 instead of manual dosing, thereby ensuring dosing uniformity and reducing the labor intensity of manual labor.

[0037] In one embodiment, the jet tube assembly 53 includes two cantilevers 531 symmetrically fixedly arranged on the clamping plate of the power hull 1, a flow equalizer 532 fixedly arranged at one end of the cantilever 531 extending into the river channel, and jet ports 533 evenly arranged and connected along the axial direction of the flow equalizer 532, and the flow equalizer 532 is connected to the liquid outlet of the metering diaphragm pump 52.

[0038] With this design, the cantilever 531 provides good support for the flow-leveling pipe 532, so that it can be firmly extended into the water of the river. The expanded microbial agent pumped out from the metering diaphragm pump 52 enters the flow-leveling pipe 532 and is sprayed out from each jet port 533 into the water of the river. Compared with manual addition, it saves time and effort and the addition is more uniform.

[0039] In one embodiment, the water inlet filter assembly 4 includes a water pump 41 fixedly arranged on the outer wall of the insulation outer tank 32, an activated carbon filter element 42, a reverse osmosis membrane filter element 43, and a coarse filtration anti-blocking assembly 44 connected to the water pump end of the water pump 41 and placed in the river channel, the water outlet end of the water pump 41 is connected to the water inlet end of the activated carbon filter element 42, the water outlet end of the activated carbon filter element 42 is connected to the water inlet end of the reverse osmosis membrane filter element 43, the pure water outlet of the reverse osmosis membrane filter element 43 is connected to the expansion inner tank 31, and the wastewater outlet is connected to the sewage pipe 45 and discharged to the river channel.

[0040] Designed in this way, the water pump 41 draws water from the river channel through the coarse filtration anti-blocking component 44, and uses the coarse filtration anti-blocking component 44 to filter out large-volume and large-particle impurities therein, and then pumps the water into the activated carbon filter element 42 and the reverse osmosis membrane filter element 43 in sequence. After fine filtration by the two filter elements, impurities such as bacteria, viruses, suspended sediment, heavy metal ions, etc. in the river water that affect the expansion of microbial agents are filtered out, and the obtained pure water is injected into the expansion tank 31, and the waste water is discharged back to the river channel from the sewage pipe 45.

[0041] In one embodiment, the coarse filtration anti-blocking assembly 44 includes a disc-shaped filter housing 441, a filter screen 442 arranged at the hollow part of the side wall of the disc-shaped filter housing 441, a cylinder 443 fixedly arranged at the top of the disc-shaped filter housing 441, a cylindrical filter cage 444 arranged in the inner cavity of the cylinder 443, and an adapter 445 connected to the top of the filter cage 444 and passing through the top of the cylinder 443. The water pumping end of the water pump 41 is connected to the adapter 445 using a water pipe.

[0042] With this design, the filter screen 442 on the disc-shaped filter housing 441 performs preliminary filtration of garbage and large particles of debris in the water body, while the filter cage 444 has smaller filtration particles, which can further filter the above impurities and reduce the filtration pressure of the activated carbon filter element 42 and the reverse osmosis membrane filter element 43.

[0043] In one embodiment, a water bath heating assembly 6 is provided in the water bath cavity 33 for heating the inner expansion tank 31. The water bath heating assembly 6 includes a water injection port 61 and a drainage valve pipeline 62 respectively arranged at the top and bottom of the outer wall of the insulation outer tank 32, a plurality of electric heating tubes 63 fixedly arranged in the water bath cavity 33, and a temperature sensor 64 arranged in the inner expansion tank 31.

[0044] With this design, after clean water is injected into the water bath cavity 33 through the water inlet 61, the electric heating tube 63 is used to heat the water in the water bath cavity 33. After the water is heated, the heat is evenly transferred to the expansion and cultivation inner tank 31, and the mixture of the microbial agent, the water and the nutrient medium in the expansion and cultivation inner tank 31 can be evenly heated to prevent the inactivation of the microbial agent due to local high temperature, and the temperature sensor 64 can detect the temperature in the expansion and cultivation inner tank 31 in real time, so as to regulate the heating effect of the electric heating tube 63 with the help of the control element, and ensure the stability and duration of the heating temperature. When the water in the water bath cavity 33 needs to be replaced, the drain valve pipeline 62 is opened, and the water therein is automatically discharged under its own water pressure.

[0045] In one embodiment, an air intake filter assembly 7 is provided on the outer wall of the thermal insulation outer tank 32, including an air pump 71 and an air filter element 72 fixedly arranged on the outer wall of the thermal insulation outer tank 32, and an air supply hose 73 with one end connected to the air outlet end of the air filter element 72 and the other end connected to the top of the upper cover 34. The exhaust end of the air pump 71 is connected to the air outlet end of the air filter element 72.

[0046] With this design, the air pump 71 draws air and pumps it into the air filter element 72 for filtration, thereby removing substances that affect the effect and efficiency of the expansion of the microbial inoculant. The filtered clean air is transported by the air hose 73 into the expansion inner tank 31, providing a clean air source for subsequent aeration.

[0047] In one embodiment, the inner cavity of the expansion tank 31 is provided with an aeration stirring assembly 8, including an air inlet pipe 81 fixedly arranged on the upper cover 34 and connected to the air supply hose 73, a first rotary joint 82 threadedly arranged at the bottom of the air inlet pipe 81, a stirring blade assembly 83 threadedly arranged at the bottom of the first rotary joint 82, a second rotary joint 84 threadedly arranged at the bottom of the stirring blade assembly 83, and an aeration plate 85 fixedly arranged at the bottom of the second rotary joint 84.

[0048] With this design, clean air is transported through the air inlet pipe 81 and flows into the aeration plate 85 and the stirring blade assembly 83. The aeration plate 85 starts to aerate, and the stirring blade assembly 83 starts to rotate around the axis of the first rotary joint 82 and the second rotary joint 84, stirring the liquid in the expansion tank 31. Under the joint action of the two, the expansion effect and efficiency are improved.

[0049] In one embodiment, the stirring blade assembly 83 includes a hollow two-way joint 831, two stirring paddles 832 symmetrically arranged on the outer wall of the two-way joint 831, an air duct hole 833 opened in the axial direction of the stirring paddle 832 and connected to the inner cavity of the two-way joint 831, and a plurality of injection holes 834 opened on the side walls of the stirring paddle 832 and connected to the air duct hole 833, and the injection holes 834 on the two stirring paddles 832 face opposite directions.

[0050] With this design, the clean air entering the two-way joint 831 is further transported to the air inlet 833 and ejected from the air jet hole 834, driving the stirring paddle 832 to rotate, thereby achieving the stirring effect of the stirring blade assembly 83 without the need for additional power input.

[0051] It should be noted that in order to prevent the liquid in the expansion tank 31 from entering the air inlet hole 833 through the jet hole 834 and finally entering the aeration plate 85, thereby affecting the aeration effect of the aeration plate 85, the diameter of the jet hole 834 should not be too large, and the air pump 71 should be kept in an open state to maintain the gas pressure at the jet hole 834 to prevent liquid from entering.

[0052] In one embodiment, a control panel 9 is fixedly installed on the outer wall of the heat-insulating outer tank 32, and the metering diaphragm pump 52, the water pump 41, the electric heating tube 63, the temperature sensor 64, and the air pump 71 are electrically connected to the control panel 9 and are also electrically connected to the portable generator 2.

[0053] With this design, the control circuit in the control panel 9 provides support for the temperature sensor 64 to regulate the electric heating tube 63, and the control panel 9 can control the on / off start / stop of the above-mentioned electrical components and electrical appliances, and the portable generator 2 supplies power.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
