Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, and specifically relates to a plasma effect device for killing insect eggs. Background Technology

[0002] Throughout the entire process of grain harvesting, drying, and storage, some pest eggs are easily trapped inside the grain. These eggs are highly resilient and difficult to conceal, and will hatch once environmental conditions are suitable, leading to a cycle of pest infestation. Therefore, in order to prevent damage to stored grain, it is necessary to regularly kill the insect eggs inside the grain.

[0003] Currently, the control of stored grain pests and their eggs mainly relies on chemical fumigants and protective agents. While these chemical methods can quickly kill insect eggs, these pesticide molecules can easily remain in the grain. When people consume grain containing pesticide molecules over a long period, these molecules can increase the metabolic burden on the human body and pose a potential risk of inducing chronic diseases and even cancer. These risks compromise the green storage of grain. Utility Model Content

[0004] To address the problem that chemical residues can easily remain in grain when insect eggs are killed using chemical methods, this invention proposes a plasma effect device for killing insect eggs, thereby overcoming the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a plasma effect device for killing insect eggs, comprising a movable frame, a mounting frame on the top of the movable frame, a plasma field effect device fixedly mounted on the top of the mounting frame, an electrode assembly at the bottom of the plasma field effect device, a rotating assembly inside the mounting frame and being poweredly connected to the electrode assembly, a gas transport assembly at the bottom of the mounting frame and being connected to the electrode assembly, and a lifting assembly on the outside of the movable frame and being connected to the mounting frame. The lifting assembly is used to drive the mounting frame to move downward so that the electrode assembly and the gas transport assembly are inserted into the grain pile to a predetermined depth. The plasma field effect device establishes an ionizing electric field inside the grain pile through the electrode assembly. The gas transport assembly is used to transport gas to the ionizing electric field so that the ionizing electric field ionizes the gas, thereby generating high-energy free electrons and low-temperature ions. At the same time, ultraviolet radiation is generated during the low-temperature plasma generation process.

[0006] Furthermore, the electrode assembly includes a high-voltage conductive slip ring, which is fixedly installed at the bottom of the plasma field effect device. The high-voltage conductive slip ring extends into the interior of the mounting frame. An electrode spindle is fixedly installed at the rotating end of the high-voltage conductive slip ring. The electrode spindle passes through the mounting frame, and several electrode rods are fixedly connected to the outer surface of the electrode spindle.

[0007] Furthermore, the rotating assembly includes an insulating sleeve, which is fixedly connected to the outer surface of the electrode spindle and rotatably connected to the mounting bracket. A driven gear is fixedly connected to the outer surface of the insulating sleeve, and a driving gear meshes with the outer surface of the driven gear. A shielding box is fixedly installed at the bottom of the inner wall of the mounting bracket, and a rotary motor is fixedly installed at the top of the shielding box. The output end of the rotary motor is fixedly connected to the driving gear.

[0008] Furthermore, the gas transport assembly includes a gas transfer box, which is fixedly installed at the bottom of the mounting frame. A shielding ring is rotatably connected to the opening of the gas transfer box, and a transport main pipe is fixedly connected to the bottom of the shielding ring. A transport branch pipe is fixedly connected to the outer surface of the transport main pipe. Air holes are opened on the outer surfaces of both the transport main pipe and the transport branch pipe. A connecting plate is fixedly connected to the outer surface of the transport main pipe and the electrode spindle. An air inlet pipe is fixedly connected to the outer surface of the gas transfer box.

[0009] Furthermore, the inner wall of the gas transfer box is provided with a sealing groove, and a sealing ring is movably connected inside the sealing groove. The sealing ring is fixedly connected to the shielding ring.

[0010] Furthermore, the lifting assembly includes a C-shaped lifting plate, two of which are fixedly connected to the mounting frame. A lifting screw is rotatably connected inside the movable frame, and the lifting screw is threadedly connected to the corresponding C-shaped lifting plate. A guide rod is fixedly connected inside the movable frame, and the guide rod is movably connected to the corresponding C-shaped lifting plate. A lifting motor is fixedly installed at the bottom of the movable frame, and the output end of the lifting motor is fixedly connected to the lifting screw.

[0011] Furthermore, several casters are fixedly installed at the bottom of the mobile frame.

[0012] This utility model has the following beneficial effects: This invention uses a lifting assembly to insert the electrode assembly and gas transport assembly into the grain pile at a predetermined depth. The plasma field effect device then establishes an ionization field inside the grain pile through the electrode assembly, while the gas transport assembly transports gas into the ionization field. This causes the gas to ionize and generate a low-temperature plasma containing high-energy free electrons, low-temperature ions, and ultraviolet radiation. Under the synergistic effect of the active components in the plasma and ultraviolet radiation, insect eggs inside the grain pile can be killed. Since the entire process does not require the participation of any chemical agents, the green and healthy storage of grain can be guaranteed.

[0013] This invention drives a rotary motor, causing the drive gear to rotate the electrode spindle and electrode rod inside the grain pile via the driven gear and insulating sleeve. Simultaneously, the transport main pipe rotates synchronously inside the grain pile along with the electrode spindle. In this configuration, the transport main pipe and transport branch pipe can continuously transport gas to the ionization field generated at the electrode spindle and electrode rod. This allows the high-energy free electrons and low-temperature ions produced by the gas ionization to be evenly distributed inside the grain pile, thereby further improving the effectiveness in killing insect eggs.

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figure 1 - Figure 6 As shown, this utility model is a plasma effect device for killing insect eggs, including a movable frame 1, a mounting frame 2 on the top of the movable frame 1, a plasma field effect device 3 fixedly mounted on the top of the mounting frame 2, an electrode assembly 4 at the bottom of the plasma field effect device 3, a rotating assembly 5 inside the mounting frame 2, the rotating assembly 5 being poweredly connected to the electrode assembly 4, a gas transport assembly 6 at the bottom of the mounting frame 2 being connected to the electrode assembly 4, and a lifting assembly 7 on the outside of the movable frame 1 being connected to the mounting frame 2. The lifting assembly 7 is used to drive the mounting frame 2 to move downwards so that the electrode assembly 4 and the gas transport assembly 6 are inserted into the grain pile to a predetermined depth. The plasma field effect device 3 establishes an ionizing electric field inside the grain pile through the electrode assembly 4. The gas transport assembly 6 is used to transport gas to the ionizing electric field so that the ionizing electric field ionizes the gas, thereby generating high-energy free electrons and low-temperature ions. At the same time, ultraviolet radiation is generated during the low-temperature plasma generation process.

[0021] The mounting frame 2 is moved to the upper part of the grain pile by the moving frame 1. Then, the lifting component 7 moves the electrode assembly 4 and the gas transport assembly 6 downward through the mounting frame 2, so that the electrode assembly 4 and the gas transport assembly 6 are inserted into the grain pile to a predetermined depth. Then, the rotating component 5 is driven so that the electrode assembly 4 and the gas transport assembly 6 can rotate slowly inside the grain pile. During this process, the plasma field effect device 3 establishes an ionizing electric field inside the grain pile through the electrode assembly 4, and the gas transport assembly 6 transports gas into the ionizing electric field, so that the gas is ionized in the ionizing electric field, thereby generating high-energy free electrons and low-temperature ions, and at the same time generating ultraviolet radiation. At this time, the active particles in the plasma and the ultraviolet radiation work together to kill the insect eggs inside the grain pile.

[0022] After the electrode assembly 4 and the gas transport assembly 6 are inserted into the grain pile to a predetermined depth by the lifting assembly 7, the plasma field effect device 3 establishes an ionization electric field inside the grain pile through the electrode assembly 4, while the gas transport assembly 6 transports the gas into the ionization electric field, thereby causing the gas to ionize and generate a low-temperature plasma containing high-energy free electrons, low-temperature ions and ultraviolet radiation. Under the synergistic effect of the active ingredients in the plasma and ultraviolet radiation, insect eggs inside the grain pile can be killed. Since the whole process does not require the participation of any chemical agents, the green and healthy storage of grain can be guaranteed.

[0023] In one embodiment, the electrode assembly 4 includes a high-voltage conductive slip ring 401, which is fixedly installed at the bottom of the plasma field effect device 3. The high-voltage conductive slip ring 401 extends into the interior of the mounting frame 2. An electrode spindle 402 is fixedly installed at the rotating end of the high-voltage conductive slip ring 401. The electrode spindle 402 passes through the mounting frame 2, and a plurality of electrode rods 403 are fixedly connected to the outer surface of the electrode spindle 402.

[0024] The plasma field effect device 3 is essentially a high-voltage power source. The thousands of volts of AC high-voltage electricity it generates is continuously supplied to the electrode spindle 402 via the high-voltage conductive slip ring 401, and then conducted to all the electrode rods 403. At this time, a strong alternating electric field is established between the tips and surfaces of each electrode rod 403. This configuration allows the electrode spindle 402 to drive several electrode rods 403 into the interior of the grain pile, creating distributed ionization regions between the particles within the grain pile. When the rotating assembly 5 drives the electrode spindle 402 and the electrode rods 403 to rotate inside the grain pile, the connection between the electrode spindle 402 and the plasma field effect device 3 remains normal with the assistance of the high-voltage conductive slip ring 401.

[0025] In one embodiment, the rotating assembly 5 includes an insulating sleeve 501, which is fixedly connected to the outer surface of the electrode spindle 402. The insulating sleeve 501 is rotatably connected to the mounting bracket 2. A driven gear 502 is fixedly connected to the outer surface of the insulating sleeve 501, and a driving gear 503 meshes with the outer surface of the driven gear 502. A shielding box 504 is fixedly installed at the bottom of the inner wall of the mounting bracket 2, and a rotary motor 505 is fixedly installed at the top of the shielding box 504. The output end of the rotary motor 505 is fixedly connected to the driving gear 503.

[0026] The rotating motor 505 drives the drive gear 503, which in turn drives the electrode spindle 402 to rotate via the driven gear 502 and the insulating sleeve 501. This arrangement allows the electrode spindle 402 and several electrode rods 403 to rotate inside the grain pile, thereby ensuring that the ionizing electric field generated by both can be evenly distributed inside the grain pile, and also providing a good environment for the subsequent killing of insect eggs. In the above arrangement, the insulating sleeve 501 prevents the high-voltage current flowing on the electrode spindle 402 from flowing to the two gears, and also avoids damage to the rotating motor 505 due to the high-voltage current.

[0027] In one embodiment, the gas transport assembly 6 includes a gas transfer box 601, which is fixedly installed at the bottom of the mounting frame 2. A shielding ring 602 is rotatably connected to the opening of the gas transfer box 601. A transport main pipe 603 is fixedly connected to the bottom of the shielding ring 602. A transport branch pipe 604 is fixedly connected to the outer surface of the transport main pipe 603. Both the outer surfaces of the transport main pipe 603 and the transport branch pipe 604 are provided with air holes 605. A connecting plate 606 is fixedly connected to the outer surface of the transport main pipe 603 and the electrode spindle 402. An air inlet pipe 607 is fixedly connected to the outer surface of the gas transfer box 601.

[0028] The air inlet pipe 607 is connected to an external air source, and the diameter of the air hole 605 is smaller than the diameter of the grain particles. When the main transport pipe 603 moves several transport branch pipes 604 into the grain pile, the air source transports the airflow to the inside of the gas transfer box 601 through the air inlet pipe 607. At this time, the airflow inside the gas transfer box 601 can flow directly into the inside of the main transport pipe 603 and the transport branch pipes 604, and the airflow inside both is sprayed into the inside of the grain pile through several air holes 605.

[0029] The airflow inside the grain pile, under the ionization of the electric field, generates high-energy free electrons and lower-temperature ions. The lower ion temperature keeps the entire reaction system at a low temperature, which greatly reduces energy consumption. Due to the significant mass difference between electrons and ions, the energy flow direction of the plasma can be well controlled by applying an external electric field. The etching effect of plasma utilizes this characteristic, which creates depressions and cracks on the surface of whole grain samples, facilitating moisture penetration and improving eating quality. Low-temperature plasma generates active ingredients. The inelastic collisions between particles in the plasma system provide excitation energy for chemical reactions, producing unique, highly reactive active particles, mainly including excited-state particles, reactive oxygen species (ROS), reactive nitrogen species (RNS), and OH radicals. These active ingredients play an important role in the sterilization process of whole grains and can also undergo physicochemical reactions with molecules on the surface of whole grains, causing them to be degraded or modified. Ultraviolet radiation is generated during the low-temperature plasma generation process, and ionized ultraviolet light can be used for grain surface treatment and the control of stored grain pests.

[0030] In one embodiment, for the gas transfer box 601, a sealing groove 608 is provided on the inner wall of the gas transfer box 601, and a sealing ring 609 is movably connected inside the sealing groove 608. The sealing ring 609 is fixedly connected to the shielding ring 602.

[0031] When the electrode spindle 402 drives the transport pipe 603 to rotate via the connecting plate 606, the transport pipe 603 can drive the shielding ring 602 to rotate inside the gas transfer box 601. The rotating shielding ring 602 can then drive the sealing ring 609 to rotate inside the sealing groove 608. In the above configuration, since the transport pipe 603 can rotate synchronously with the electrode spindle 402 inside the grain pile, this configuration allows the transport pipe 603 and the transport branch pipe 604 to continuously transport gas to the ionization electric field generated at the electrode spindle 402 and the electrode rod 403. At the same time, the high-energy free electrons and low-temperature ions generated by gas ionization can be evenly distributed inside the grain pile, thereby further improving the effect of killing insect eggs.

[0032] The sealing ring 609 and the sealing groove 608 ensure that the sealing effect of the shielding ring 602 can be guaranteed while the shielding ring 602 can rotate inside the gas transfer box 601.

[0033] In one embodiment, the lifting assembly 7 includes a U-shaped lifting plate 701. Two U-shaped lifting plates 701 are fixedly connected to the mounting frame 2. A lifting screw 702 is rotatably connected inside the movable frame 1. The lifting screw 702 is threadedly connected to the corresponding U-shaped lifting plate 701. A guide rod 703 is fixedly connected inside the movable frame 1. The guide rod 703 is movably connected to the corresponding U-shaped lifting plate 701. A lifting motor 704 is fixedly installed at the bottom of the movable frame 1. The output end of the lifting motor 704 is fixedly connected to the lifting screw 702.

[0034] When the moving frame 1 moves the mounting frame 2 to the upper side of the grain pile, the lifting motor 704 drives the lifting screw 702. At this time, the rotating lifting screw 702 can drive the mounting frame 2 to move downward through the C-shaped lifting plate 701, so that the electrode spindle 402, electrode rod 403, transport main pipe 603 and transport branch pipe 604 at the bottom of the mounting frame 2 can be inserted into the interior of the grain pile. During the above process, the guide rod 703 can guide the mounting frame 2 through the corresponding C-shaped lifting plate 701, so that the overall stability of the mounting frame 2 can be guaranteed when it is raised and lowered.

[0035] In one embodiment, for the aforementioned movable frame 1, a plurality of omnidirectional wheels 8 are fixedly installed at the bottom end of the movable frame 1.

[0036] The casters 8 can move the mounting frame 2 via the movable frame 1, which makes it convenient to transport the device.

[0037] Through the above technical solution, 1. After the electrode assembly 4 and the gas transport assembly 6 are inserted into the grain pile to a predetermined depth by the lifting assembly 7, the plasma field effect device 3 establishes an ionization electric field inside the grain pile through the electrode assembly 4, while the gas transport assembly 6 transports the gas into the ionization electric field, thereby causing the gas to ionize and generate a low-temperature plasma containing high-energy free electrons, low-temperature ions, and ultraviolet radiation; under the synergistic effect of the active components in the plasma and ultraviolet radiation, insect eggs inside the grain pile can be killed, and since the entire process does not require the participation of any chemical agents, the green and healthy storage of grain can be guaranteed; 2. By rotating the electric field... The machine 505 drives the main shaft 402 and electrode rod 403 to rotate inside the grain pile via the driven gear 502 and insulating sleeve 501. At the same time, the transport main pipe 603 can rotate synchronously inside the grain pile along with the main shaft 402. In the above configuration, the transport main pipe 603 and transport branch pipe 604 can continuously transport gas to the ionization field generated at the main shaft 402 and electrode rod 403. This allows the high-energy free electrons and low-temperature ions generated after gas ionization to be evenly distributed inside the grain pile, thereby further improving the effect of killing insect eggs.
