Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide degradation technology, specifically to a pesticide degradation device. Background Technology
[0002] With the rapid development of modern agriculture and industry, pesticides play a vital role in ensuring crop yields and controlling pests and diseases. However, the widespread use of pesticides has also brought serious environmental problems, especially the pollution of water bodies caused by excessive pesticide residues, which directly threatens human health and ecological balance.
[0003] In agricultural production, irrigation water is crucial for crop growth, but it may contain pesticide residues from various sources, including surrounding pesticide use and soil seepage. After use, pesticide spraying equipment often leaves significant residues; direct discharge without proper treatment can pollute surrounding soil and water bodies. In industrial settings, pesticide factories generate large amounts of wastewater containing high concentrations of pesticides during production; direct discharge of this wastewater poses a significant environmental hazard. In residential and commercial settings, tap water or groundwater may be contaminated by the surrounding environment, resulting in residues of organophosphates, pyrethroids, and other pesticides. These residues can damage the nervous, immune, and reproductive systems, and long-term ingestion may increase the risk of cancer.
[0004] Given the severity of pesticide residue problems in water under various scenarios, the effective degradation and purification of pesticides in water has become an urgent task. Currently, existing pesticide degradation devices on the market mainly employ technologies such as electrolysis, deep oxidation, ultrasound, or photocatalysis to achieve pesticide degradation. These existing pesticide degradation devices mostly suffer from high investment and operating costs, which greatly limits their applicability. They are more suitable for applications such as pesticide factories that need to treat large volumes of pesticide production wastewater. However, for small-volume treatment scenarios such as farmland irrigation water treatment, pesticide spraying equipment residue treatment, and small-volume pesticide residue removal in household and commercial settings, they cannot meet practical needs due to excessive costs and operational complexity.
[0005] In conclusion, developing a pesticide degrader that can be applied to multiple scenarios and has a relatively low cost is of great practical significance. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] This invention provides a pesticide degrader, which can at least solve the technical problem of how to expand its applicable scope.
[0008] (II) Technical Solution
[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pesticide degradation device, comprising a catalytic module, a delivery pump and a multi-stage filtration module connected in sequence;
[0010] The inlet end of the catalytic module is connected to an inlet pipe, which is used to connect to an external water source to supply raw water to the pesticide degrader. The catalytic module is used to add catalyst to the raw water.
[0011] The delivery pump is used to deliver raw water, allowing it to flow sequentially through the catalytic module and the multi-stage filtration module.
[0012] The multi-stage filtration module includes a PP cotton filter tank, a granular activated carbon filter tank, and a compressed activated carbon filter tank connected in sequence along the water delivery direction. The PP cotton filter tank, granular activated carbon filter tank, and compressed activated carbon filter tank are used to filter raw water mixed with catalyst in sequence. The outlet end of the compressed activated carbon filter tank is connected to an outlet pipe, which is used to discharge the filtered purified water.
[0013] In a further configuration, the aforementioned catalytic module includes at least two catalyst containers connected in sequence, each used to store the catalyst and mix it into the raw water.
[0014] Furthermore, the aforementioned pesticide degradation device also includes:
[0015] The mounting frame has two placement spaces on each side. The multi-stage filter module is installed in one of the placement spaces, and the delivery pump is installed in the other placement space. The PP cotton filter canister, granular activated carbon filter canister and compressed activated carbon filter canister are arranged alternately on the same straight line.
[0016] The limiting seat is fixed at the top of the mounting frame. The number of limiting seats is the same as that of the catalyst containers and they are set one-to-one. The limiting seat is used to place and limit the corresponding catalyst container.
[0017] In a further configuration, the aforementioned catalyst container is cylindrical, and the limiting seat has an arc-shaped concave surface for contacting the surface of the catalyst container.
[0018] Furthermore, the aforementioned catalyst container is provided in two parts, and correspondingly, two limiting seats are provided. The two limiting seats are at different heights, so that the downstream catalyst container is higher than the upstream catalyst container.
[0019] Furthermore, the aforementioned pesticide degrader also includes a chassis, with a mounting bracket fixed inside the chassis. The chassis has a transparent viewing window at the position corresponding to the multi-stage filtration module. The PP cotton filter canister, granular activated carbon filter canister, and compressed activated carbon filter canister all include a transparent outer shell and a filter element, with the filter element being detachably installed inside the transparent outer shell.
[0020] Further configuration: the aforementioned delivery pump is a high-pressure pump, and the outlet end of the water pipe is connected to a pure water tank, which is used to hold the filtered purified water.
[0021] The pesticide degrader also includes a pressure sensing device and a high-pressure switch. The pressure sensing device is located inside the pure water tank and is used to sense the water pressure inside the pure water tank. The high-pressure switch is electrically connected to both the pressure sensing device and the high-pressure pump. The high-pressure switch is used to control the high-pressure pump to start or stop based on the water pressure value sensed by the pressure sensing device.
[0022] Furthermore, the aforementioned pesticide degrader also includes a pressure tank, which is connected to the catalytic module and is used to stabilize the water pressure inside the pesticide degrader.
[0023] (III) Beneficial Effects
[0024] Compared with the prior art, the pesticide degrader provided by this utility model has the following beneficial effects:
[0025] When using the pesticide degradation device provided by this utility model, firstly, raw water containing pesticide residues is introduced into the device through the inlet pipe. Then, a delivery pump provides power, driving the raw water from the inlet pipe into the catalytic module. The catalytic module adds catalyst to the raw water. Subsequently, the delivery pump drives the raw water mixed with catalyst to flow sequentially into a PP cotton filter tank, a granular activated carbon filter tank, and a compressed activated carbon filter tank for filtration. The PP cotton filter tank can filter out large particulate impurities in the water, such as silt, rust, and suspended solids. The granular activated carbon filter tank has a porous structure, which can effectively adsorb odors and discoloration in the water, adsorb organic matter such as pesticide residues and fertilizers, and intercept fine particles. The compressed activated carbon filter tank has a finer porous structure than granular activated carbon, which can intercept even finer particles in the raw water, further adsorbing organic matter and odors in the raw water, and improving the taste of the water. Finally, the delivery pump drives the filtered purified water to flow out of the pesticide degradation device through the outlet pipe for discharge or use.
[0026] As can be seen, this invention, through the combination of a catalytic module and a multi-stage filtration module, can rapidly degrade pesticide residues in water. Compared with traditional pesticide degradation methods such as electrolysis, deep oxidation, ultrasound, or photocatalysis, the catalyst used in the catalytic module of this invention is relatively inexpensive. Furthermore, the filter materials used in the multi-stage filtration module, such as PP cotton, granular activated carbon, and compressed activated carbon, are affordable and have a long replacement cycle, significantly reducing material costs. Simultaneously, the equipment does not consume large amounts of energy during operation, is simple to operate, and requires no complex maintenance or management by professional technicians, further reducing labor and operating costs. Therefore, this invention is not only suitable for large-scale wastewater treatment plants such as pesticide factories, but also for applications such as farmland irrigation water treatment, pesticide spraying equipment residue treatment, and small-volume pesticide residue removal in household and commercial settings. It supports filtration of different water sources, including tap water, well water, and river water, effectively expanding its applicability. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] This invention provides a pesticide degradation device to address the problem of expanding its applicability.
[0038] See Figure 1 and Figure 2 As shown, Figure 1 This is a first-view perspective perspective view of the pesticide degrader in the embodiment. Figure 2 The pesticide degrader in the embodiment is a perspective view from a second angle. The pesticide degrader includes a catalytic module 1, a delivery pump 2, and a multi-stage filtration module 3 connected in sequence.
[0039] The inlet of the catalytic module 1 is connected to an inlet pipe 11, which is used to connect to an external water source to supply raw water to the pesticide degrader. The catalytic module 1 is used to add catalyst to the raw water.
[0040] Pump 2 is used to transport raw water, which flows sequentially through catalytic module 1 and multi-stage filtration module 3. Multi-stage filtration module 3 includes a PP cotton filter tank 31, a granular activated carbon filter tank 32, and a compressed activated carbon filter tank 33 connected sequentially along the water delivery direction. The PP cotton filter tank 31, granular activated carbon filter tank 32, and compressed activated carbon filter tank 33 are used to sequentially filter the raw water mixed with the catalyst. The outlet end of the compressed activated carbon filter tank 33 is connected to an outlet pipe 34, which allows the filtered purified water to flow out.
[0041] When using the pesticide degradation device described above, firstly, raw water containing pesticide residues is introduced into the device through the inlet pipe 11. Then, the delivery pump 2 provides power, driving the raw water from the inlet pipe 11 into the catalytic module 1. The catalytic module 1 adds catalyst to the raw water. Subsequently, the delivery pump 2 drives the raw water mixed with catalyst to flow sequentially into the PP cotton filter tank 31, the granular activated carbon filter tank 32, and the compressed activated carbon filter tank 33 for filtration. The PP cotton filter tank 31 can filter large particulate impurities in the water, such as silt, rust, and suspended solids. The granular activated carbon filter tank 32 has a porous structure, which can effectively adsorb odors and discoloration in the water, adsorb organic matter such as pesticide residues and fertilizers, and intercept fine particles. The compressed activated carbon filter tank 33 has a finer porous structure than granular activated carbon, which can intercept even finer particles in the raw water, further adsorbing organic matter and odors in the raw water, and improving the taste of the water. Finally, the delivery pump 2 drives the filtered purified water to flow out of the pesticide degradation device through the outlet pipe 34 for discharge or use. As can be seen, this invention, through the combination of catalytic module 1 and multi-stage filtration module 3, can rapidly degrade pesticide residues in water. Compared with traditional pesticide degradation methods such as electrolysis, deep oxidation, ultrasound, or photocatalysis, the catalyst used in catalytic module 1 of this invention has a relatively low cost. Moreover, the filter materials used in multi-stage filtration module 3, such as PP cotton, granular activated carbon, and compressed activated carbon, are affordable and have a long replacement cycle, greatly reducing material costs. Simultaneously, the equipment does not consume a large amount of energy during operation, is simple to operate, and requires no complex maintenance and management by professional technicians, further reducing labor and operating costs. Therefore, this invention is not only suitable for large-scale wastewater treatment plants such as pesticide factories, but also for applications such as farmland irrigation water treatment, pesticide spraying equipment residue treatment, and small-volume pesticide residue removal in household and commercial settings. It supports filtration of different water sources such as tap water, well water, and river water, effectively expanding its applicability.
[0042] The inlet of the aforementioned water inlet pipe 11 can be adapted to a faucet interface for quick connection to an external water source.
[0043] Furthermore, the bottom of this pesticide degrader can be fitted with feet or wheels to better adapt to muddy field environments, thereby further expanding its applicability. If the pesticide degrader is used in home / commercial settings, all materials in contact with water must be water-resistant and chemically resistant, making it food-grade. This not only extends the device's lifespan but also ensures the safety of the purified water it produces for drinking.
[0044] See Figure 2As shown, in one embodiment of the catalytic module 1, the catalytic module 1 includes at least two catalyst containers 12 connected in sequence. Both catalyst containers 12 are used to store catalysts and mix them into the raw water. Thus, when the raw water flows through the catalyst containers 12, it can mix with the catalysts within the catalyst containers 12, simultaneously carrying the catalysts into the multi-stage filtration module 3, thereby achieving the effect of adding catalysts to the raw water.
[0045] The aforementioned catalytic module 1 may also include a catalyst addition device connected to the catalyst container 12. The catalyst addition device may use a metering pump to control the amount of catalyst added.
[0046] The above-mentioned at least two catalyst containers 12 can be used to store the same catalyst or different catalysts, and can be adjusted according to the actual degradation of pesticides.
[0047] See Figure 1 and Figure 2 As shown, based on the above embodiment, the pesticide degrader also includes a mounting frame 4 and a limiting seat 5. Two placement spaces 41 are provided on each side of the mounting frame 4. The multi-stage filtration module 3 is installed in one placement space 41, and the delivery pump 2 is installed in the other placement space 41. PP cotton filter canisters 31, granular activated carbon filter canisters 32, and compressed activated carbon filter canisters 33 are arranged at intervals along a straight line. The limiting seat 5 is fixed to the top of the mounting frame 4 by welding or screwing. The number of limiting seats 5 is the same as the number of catalyst containers 12, and they are arranged in a one-to-one correspondence. The limiting seat 5 is used to place and limit the corresponding catalyst container 12. Thus, the mounting frame 4 and the limiting seat 5 allow for a reasonable layout of the various components of the pesticide degrader, keeping them in a fixed position to maintain overall stability and facilitating disassembly, assembly, and maintenance.
[0048] See Figure 1 and Figure 2 As shown, in one embodiment of the catalyst container 12, the catalyst container 12 is cylindrical. The limiting seat 5 has an arc-shaped concave surface 51, which is used to contact the surface of the catalyst container 12. In this way, the limiting seat 5 can limit the position of the catalyst container 12 through the concave surface 51 and stably support the catalyst container 12, thereby improving the installation stability of the catalyst container 12.
[0049] See Figure 1 and Figure 2As shown, based on the above embodiment, two catalyst containers 12 are provided, and two corresponding limiting seats 5 are provided. The two limiting seats 5 have different heights, so that the downstream catalyst container 12 is higher than the upstream catalyst container 12. In this way, this design of different heights allows the raw water to fully contact and mix with the catalyst in the upstream catalyst container 12 before flowing into the downstream catalyst container 12 for further mixing, effectively enhancing the contact and mixing effect between water and catalyst.
[0050] Based on the above embodiments, the pesticide degrader may also include a chassis (not shown in the figure). A transparent viewing window (not shown in the figure) is installed on the chassis corresponding to the position of the multi-stage filtration module 3. The PP cotton filter tank 31, granular activated carbon filter tank 32, and compressed activated carbon filter tank 33 each include a transparent outer shell 35 and a filter element (not shown in the figure). The filter element is detachably installed inside the transparent outer shell 35 by magnetic attraction or screwing, facilitating user replacement. The mounting bracket 4 is fixed inside the chassis by screwing or welding. In this way, the chassis can protect the catalytic module 1, the delivery pump 2, and the multi-stage filtration module 3, and the combination of the transparent outer shell 35 and the transparent viewing window allows the user to directly observe the purification process of the multi-stage filtration module 3, such as the water gradually becoming clearer after flowing through the filter element. The transparent viewing window also allows the user to directly observe the degree of contamination of the filter element, facilitating timely replacement or maintenance.
[0051] Based on the above embodiments, the pesticide degrader may also include a filter cartridge life warning device (not shown in the figure). The filter cartridge life warning device can use a timer to calculate the usage time of the filter cartridge, and when it is about to expire, it can automatically remind the user to replace it through APP push or indicator light on the machine.
[0052] See Figure 2As shown, in one embodiment of the delivery pump 2, the delivery pump 2 is a high-pressure pump. The outlet end of the outlet pipe 34 is connected to a pure water tank (not shown in the figure), which is used to hold the filtered purified water. The pesticide degrader also includes a pressure sensing device (not shown in the figure) and a high-pressure switch 6. The pressure sensing device is installed inside the pure water tank and is used to sense the water pressure inside the tank. The high-pressure switch 6 is electrically connected to both the pressure sensing device and the high-pressure pump, and is used to control the high-pressure pump to start or stop based on the water pressure value sensed by the pressure sensing device. Thus, the high-pressure pump pressurizes the raw water to a pressure higher than the osmotic pressure, thereby providing a stable pressure that allows the water to flow into the pure water tank at a stable flow rate after being filtered through the multi-stage filtration module 3. When the water pressure in the pure water tank reaches or exceeds the upper limit of the high-pressure switch 6, the high-pressure switch 6 will automatically cut off the power supply to control the high-pressure pump to shut down, preventing mechanical damage or energy waste caused by the high-pressure pump continuing to run. When the water level in the pure water tank drops and the water pressure is lower than the upper limit of the high-pressure switch 6, the high-pressure switch 6 will automatically turn on the power supply to control the high-pressure pump to start and continue working. In addition, this utility model can collect filtered water through the pure water tank for convenient use.
[0053] The pressure sensing device described above can use existing pressure sensors, the high-pressure switch 6 can use existing high-pressure control switches, and the high-pressure pump can use existing booster pumps.
[0054] See Figure 2 As shown, based on the above embodiment, the pesticide degrader also includes a pressure tank 7. The pressure tank 7 is connected to the catalytic module 1. The pressure tank 7 is used to stabilize the water pressure inside the pesticide degrader so that the water flow does not fluctuate, and assists the high-pressure pump in further stabilizing the water flow rate.
[0055] The pesticide degradation device can also be equipped with a water quality monitoring system and a display screen. The water quality monitoring system can monitor the pesticide concentration in the raw water in real time, thus monitoring water quality. It can also monitor key parameters such as catalyst activity in real time, allowing for automatic adjustment of reaction conditions based on this data feedback. This makes the pesticide degradation device more flexible in treating raw water, thereby improving the degradation effect. The display screen can show users the impurity levels in the water in real time, directly providing feedback on the filtration process and results.
[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
