Description

Technical Field

[0001] This utility model relates to the field of low-oxygen insecticidal disinfection technology, specifically a low-oxygen insecticidal disinfection device with a base that can be assembled on-site at normal pressure. Background Technology

[0002] Atmospheric pressure low-oxygen insecticidal disinfection technology is an environmentally friendly treatment method that kills pests and microorganisms by reducing the oxygen concentration in the environment due to lack of oxygen. Compared with traditional chemical fumigation methods, it has significant advantages such as no chemical residue, minimal damage to items, and environmental safety, and is widely used in grain storage, preservation of traditional Chinese medicine, and protection of cultural relics.

[0003] Existing atmospheric pressure low-oxygen insecticidal and disinfection equipment is mostly designed as a single unit, which is large in size and lacks modular disassembly capabilities. In scenarios involving complex warehouse layouts, narrow door and window passages, or internal obstacles, the main body of the equipment cannot be easily transported into the work area via conventional channels. Deployment requires the removal of parts of the building structure or complex spatial modifications, significantly increasing implementation costs and reducing operational efficiency. Furthermore, the single-unit design occupies a large space during long-distance transportation, resulting in high transportation costs, and cannot be flexibly adjusted according to different warehouse sizes and usage needs, greatly limiting the widespread adoption of this technology in diverse application scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a base-mounted, on-site assembled, normal-pressure, low-oxygen insecticidal and disinfection device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A field-assembled, atmospheric pressure, low-oxygen insecticidal and disinfection device with a base includes a base, a back plate, a pair of side plates, a top plate, and a cover plate. The top surface of the base has three sets of sliding grooves. Sliding strips are installed on the bottom surfaces of the back plate, the pair of side plates, and the cover plate, and these sliding strips slide within the grooves. The inner side of the back plate has a pair of first sealing grooves. First sealing strips are installed on the sides of each pair of side plates, and the first sealing strips and first sealing grooves are interference-fitted. Sealing plates are installed on both sides of the back plate. Sealing openings are opened on the sides of each pair of side plates near the first sealing strips, and the sealing plates and sealing openings are fixedly connected by screws. Four sets of uprights are installed on the top surface of the base. The cover plate covers the top surface of the back plate and the pair of side plates and is fixedly connected to the four sets of uprights. A sealing strip is installed on the bottom surface of the cover plate. The sealing ring is pressed against the top surface of the back plate and a pair of side plates. Second sealing grooves are provided on the sides of both the side plates and the top plate. Three sets of second sealing strips are installed on the side of the cover plate, and the second sealing strips and second sealing grooves are interference-fitted. Fixing members are installed on the outer sides of the pair of side plates, pressing against the outer side of the cover plate. A nitrogen generator is provided on the side of the base, and its output end is connected to the back plate. A one-way valve is connected to the top surface of the top plate. Through modular design, the equipment can be disassembled into multiple independent components, facilitating transportation and on-site assembly, solving the problem of traditional integrated equipment being unable to pass through narrow passages. The sliding groove and sliding strip cooperate to achieve rapid positioning, and the interference-fitted connection between the sealing strip and the sealing groove ensures high airtightness, guaranteeing stability in a low-oxygen environment.

[0007] Furthermore, the fastener includes a connecting frame rotatably mounted on the side of the side plate via a pin. A pressure roller is rotatably connected inside the connecting frame. The pressure roller presses against the outer side of the cover plate. The pressure roller can rotate to press the cover plate, providing uniform pressure without damaging the surface of the cover plate, ensuring the sealing reliability between the cover plate and the side plate, and facilitating the rotation of the connecting frame to loosen the pressure roller during disassembly.

[0008] Furthermore, the slide groove includes a trapezoidal groove formed on the side of the base and a limiting groove formed on the top surface of the base. The trapezoidal groove and the limiting groove are connected. The slide bar includes a connected trapezoidal strip and a limiting strip. The limiting strip is installed on the bottom surface of the back plate, a pair of side plates, and a cover plate. The trapezoidal strip slides in the trapezoidal groove, and the limiting strip slides in the limiting groove. A third sealing strip is installed in the limiting groove. The third sealing strip compresses the limiting strip. The cooperation between the trapezoidal groove and the trapezoidal strip can limit the vertical displacement of the component. The limiting groove and the limiting strip guide each other to ensure assembly accuracy. The third sealing strip compresses the limiting strip to prevent gas leakage between the base and the component and improve the overall sealing performance.

[0009] Furthermore, a pair of fixing blocks are installed on both sides of the top plate, and the fixing blocks and the columns are fixedly connected by screws. Positioning rods are installed on the top surface of the back plate and the pair of side plates. Positioning holes are opened on the bottom surface of the top plate, and the positioning rods slide in the positioning holes. The positioning rods cooperate with the positioning holes to achieve quick positioning of the top plate. The screw connection between the fixing blocks and the columns ensures the stability of the top plate and avoids the top plate from shifting due to vibration, which would affect the sealing performance.

[0010] Furthermore, the nitrogen generator includes a base, on the top surface of which a nitrogen generator is mounted. A pipe connects the output end of the nitrogen generator to the back plate. The base supports the nitrogen generator, and the pipe connects to the back plate, allowing nitrogen to be evenly injected into the equipment to create a low-oxygen environment that meets the needs of insecticidal disinfection.

[0011] Furthermore, flanges are installed at the free ends of both the back plate and the pipe, and the flanges are fixedly connected by screws. The flange connection facilitates the disassembly and assembly of the pipe and the back plate, and the pipe can be quickly disassembled during maintenance. At the same time, the flange gasket ensures that there is no gas leakage at the connection.

[0012] Furthermore, the surface of the cover is embedded with an observation window, which allows operators to view the status of internal files and materials in real time without opening the equipment, thus avoiding frequent opening of the cover and disrupting the low-oxygen environment.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the on-site assembly atmospheric pressure low oxygen insecticidal and disinfection equipment with base can be disassembled into multiple independent parts through modular disassembly design, which is convenient for transportation and on-site assembly, and solves the problem that traditional integrated equipment is difficult to pass through narrow passages; the sliding groove and sliding strip cooperate to achieve rapid positioning, and the interference connection between the sealing strip and the sealing groove ensures high airtightness and ensures the stability of the low oxygen environment.

[0021] 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.

[0022] Please see Figures 1-6This utility model provides a technical solution: a field-assembled, atmospheric pressure, low-oxygen insecticidal and disinfection device with a base, comprising a base 1, a back plate 2, a pair of side plates 3, a top plate 4, and a cover plate 5. The top surface of the base 1 has three sets of sliding grooves. Sliding strips are installed on the bottom surfaces of the back plate 2, the pair of side plates 3, and the cover plate 5, sliding within the grooves. A pair of first sealing grooves 17 are provided on the inner side of the back plate 2. First sealing strips 13 are installed on the sides of the pair of side plates 3, with the first sealing strips 13 and the first sealing grooves 17 being interference-fitted. Sealing plates 18 are installed on both sides of the back plate 2. Sealing openings 12 are opened on the sides of the pair of side plates 3 near the first sealing strips 13. The sealing plates 18 and the sealing openings 12 are fixedly connected by screws. Four sets of uprights 9 are installed on the top surface of the base 1. The cover plate 5 covers the back plate 2, the pair of side plates 3, and the top surface of the back plate 1. The top surface of plate 3 is fixedly connected to four sets of columns 9. A sealing ring is installed on the bottom surface of cover plate 5. The sealing ring is pressed against the top surface of back plate 2 and a pair of side plates 3. The sides of the pair of side plates 3 and top plate 4 are provided with second sealing grooves 16. Three sets of second sealing strips are installed on the side of cover plate 5. The second sealing strips and the second sealing grooves 16 are interference-fitted. Fixing members are installed on the outside of the pair of side plates 3. The fixing members press against the outside of cover plate 5. A nitrogen generator is provided on the side of base 1. The output end of the nitrogen generator is connected to back plate 2. A one-way valve 21 is connected to the top surface of top plate 4. During assembly, the sliding strips of back plate 2 and side plate 3 are inserted into the sliding groove of base 1 for sliding positioning. The first sealing strip 13 is embedded in the first sealing groove 17 to form a seal. The sealing plate 18 and the sealing port 12 are fixed with screws to enhance the sealing performance. The top plate 4 is fixed to the top by the column 9. Its bottom sealing ring is pressed against the top surface of the back plate 2 and a pair of side plates 3. The second sealing strip on the side of the cover plate 5 is embedded in the second sealing groove 16, and the cover plate 5 is fixed by the fastener. The nitrogen generated by the nitrogen generator enters the back plate 2 through the pipe 8 and fills the inside of the equipment to form a low-oxygen environment. The one-way valve 21 maintains the pressure inside the cavity and prevents the outside air from flowing back in.

[0023] As an embodiment of this utility model, the fixing member further includes a connecting frame 14 rotatably mounted on the side of the side plate 3 via a pin shaft. A pressure roller 15 is rotatably connected inside the connecting frame 14. The pressure roller 15 presses against the outer side of the cover plate 5. Rotating the connecting frame 14 causes the pressure roller 15 to fit against the outer side of the cover plate 5. The rolling friction characteristics of the pressure roller are used to evenly press the cover plate to enhance the sealing of the connection between the cover plate and the side plate and prevent nitrogen leakage.

[0024] In one embodiment of this utility model, the sliding groove further includes a trapezoidal groove 10 formed on the side of the base 1 and a limiting groove 11 formed on the top surface of the base 1. The trapezoidal groove 10 and the limiting groove 11 are connected. The sliding strip includes a connected trapezoidal strip 22 and a limiting strip. The limiting strip is installed on the bottom surface of the back plate 2, a pair of side plates 3, and the cover plate 5. The trapezoidal strip 22 slides in the trapezoidal groove 10, and the limiting strip slides in the limiting groove 11. A third sealing strip is installed in the limiting groove 11. The third sealing strip squeezes the limiting strip, the trapezoidal strip 22 is inserted into the trapezoidal groove 10, and the limiting strip is embedded in the limiting groove 11. When sliding, the trapezoidal structure restricts the component from shaking up and down, and the limiting groove guides the sliding direction. The third sealing strip is deformed by the limiting strip, filling the gap and preventing gas from leaking from the connection between the base and the component.

[0025] As an embodiment of this utility model, a pair of fixing blocks 20 are installed on both sides of the top plate 4. The fixing blocks 20 and the column 9 are fixedly connected by screws.
