[0019] like Figures 1-8 As shown, a quarantine and pest control device for invasive foreign insects includes a shell 1. A tunnel 2 is provided inside the shell 1. The density of the fumigant is greater than the density of air, so that it can move downward under its own gravity. The outer surface of the tunnel 2 is provided with an inclined partition 3. The partition 3 has an inclination angle of less than 30 degrees to prevent materials from sliding under the weight and accumulating at the lower end. The surface of the partition 3 is provided with a plurality of through holes for discharging the fumigant. The surface of the partition 3 is roughened so that the goods accumulated on the surface of the partition 3 can form an inclined pile of goods (most of the goods are granular or block-shaped), and the bottom surface of the goods is inclined so that the thickness of the accumulated goods gradually becomes thicker along the direction of the partition 3. The upper end of the goods is thin and the lower end is thick. The fumigant is discharged from the upper end, so that part of the fumigant can quickly pass through the goods at the upper end to avoid residue.

[0020] The partition 3 and the corridor 2 form a pest control area A15. The triangular configuration of this area uses an inclined surface to guide the natural stacking of goods. The bottom relies on the partition 3 to form a stable support, and the top gradually narrows with the inclination angle of the partition 3, so that the thickness of the cargo stacking decreases linearly from the bottom end to the top end of the partition 3. A support frame 4 is provided on the surface of the corridor 2. The cross-section of the support frame 4 is triangular. The inclined surface of the support frame 4 is provided with a number of through holes, which are used for the discharge of fumigants. The grid structure of the support frame 4 not only bears the weight of the goods, but also reserves a channel for the flow of the fumigant. The support frame 4 and the partition 3 form a pest control area B5. The inclined surface structure enables the fumigant to flow along the inclined surface to the through holes at the bottom of the device after completing the pest control effect, thereby reducing the retention in the depressions of the goods. At the same time, the grid gap of the support frame 4 is cooperated with to accelerate the discharge efficiency of the residual fumigant.

[0021] The fumigation area A15 makes the piled goods in a triangular shape, and the thickness of the goods gradually decreases along the partition 3. When the fumigant passes through the treatment area A, a gas mass with a certain pressure is formed, which enhances the penetration of the deep gaps of the goods.

[0022] The fumigation area B5 makes the upper surface of the piled goods in a slope shape, so that the fumigant is discharged along the slope.

[0023] The space volume at the upper end of the fumigation area B5 is greater than that at the lower end, so that the fumigant diffused from the fumigation area A15 flows along the slope to the lower end with a smaller space under the dual action of gravity and pressure difference, and then gradually converges in the space at the lower end of the fumigation area B5. This not only adapts to the more compact shape of the goods stacked at the lower end, but also ensures that the deep goods contact sufficient fumigant through the gas aggregation effect, thereby improving the thoroughness of fumigation.

[0024] The middle part of the shell 1 is provided with a column 6, and the inside of the column 6 is provided with a plurality of air suction machines. The upper end of the column 6 is provided with a plurality of exhaust ports 7, and each exhaust port 7 is inclined. Each exhaust port 7 is a horn-shaped structure, and the port is inclined by twenty to thirty degrees away from the central axis of the column 6. This makes the spraying range of the circulating fumigant wider.

[0025] The middle part of the outer surface of the column 6 is provided with a restraint block 8, which is in contact with the upper end of the partition 3 and is used to support the upper end of the partition 3.

[0026] The inside of the duct 2 is respectively provided with an air suction pipe A9 and an air suction pipe B10. One end of the air suction pipe A9 is connected with one side of the duct 2 close to the fumigation area A15, and one end of the air suction pipe B10 is connected with one side of the duct 2 close to the fumigation area B5. The other ends of the air suction pipe A9 and the air suction pipe B10 are connected with the column 6, thereby forming two groups of fumigant circulation channels. The fumigant is made to penetrate the goods by suction force to reduce residue, and then the used fumigant is transported to a high place to be mixed with new fumigant for reuse, thereby reducing waste.

[0027] The size of the air suction pipe A9 is smaller than that of the air suction pipe B10, so that the flow rate of the fumigant in the air suction pipe A9 is greater than that of the fumigant in the air suction pipe B10. Under the same negative pressure condition, the flow rate of the fumigant in the air suction pipe A9 can be multiple times that in the air suction pipe B10. This makes the air suction pipe A9 quickly extract the fumigant in the triangular space of the fumigation area A15, and the dense air suction holes thereof enhance the suction and penetration effect on the deep gaps of the goods. The air suction pipe B10 is adapted to the open space of the fumigation area B5 with a larger flow rate to realize efficient circulation of the gas.

[0028] The upper surface of the shell 1 is provided with a cover plate 13, and the cover plate 13 and the shell 1 are directly provided with a sealing gasket. The upper surface of the cover plate 13 is provided with a gas chamber 14 for accommodating fumigants. The gas chamber 14 is fixedly installed on the upper surface of the cover plate 13 through a support. The bottom of the gas chamber 14 is communicated with the shell 1 through a pipeline provided with a solenoid valve, which is used for storing and quantitatively releasing fumigants. The amount of drug delivery is controlled by the pulse opening and closing of the solenoid valve, which is suitable for the pest control needs of different goods. One side of the gas chamber 14 is provided with an air inlet pipe for connecting external fumigants to supplement the gas chamber 14. One side of the shell 1 is provided with an air outlet pipe for discharging the internal fumigants, which is convenient for subsequent addition of goods and avoids poisoning. The air inlet pipe and the air outlet pipe are both provided with valves which can be freely opened according to needs.

[0029] A through slot is formed at the edge of the upper surface of the cover plate 13. A sealing plug is arranged in the through slot. The surface of the sealing plug is provided with anti-skid lines. One end of the sealing plug extends out a pull ring for easy insertion and pulling. The through slot can be flexibly opened according to the amount of goods, which is used to supplement the stacked goods in the pest control areas A15 and B5. After filling, the sealing plug is inserted to restore the air tightness of the device to avoid leakage of fumigants.

[0030] The cross section of the duct 2 is in the shape of "L". An arc-shaped groove 11 is formed at the bending part of the duct 2. A rotating shaft 12 is rotatably connected in the arc-shaped groove 11. The outer surface of the rotating shaft 12 is fixedly connected with the lower end of the partition plate 3, so that the partition plate 3 can adjust the inclination angle within the range of ten to sixty degrees around the rotating shaft 12, to adapt to the stacking needs of goods of different heights. The partition plate 3 can also be inclined to the maximum angle to fill the material downward.

[0031] In use, the fumigants stored in the gas chamber 14 have a density greater than that of air, which is quantitatively released into the shell 1 through the pipeline provided with the solenoid valve. Due to its own gravity, the fumigants move downward along the duct 2 to provide power for penetrating the goods.

[0032] In the pest control area A15, the surface of the partition plate 3 is roughened to prevent the goods from sliding off. The duct 2 is arranged to form a stacking shape with the bottom surface inclined and the upper end thin and the lower end thick. The duct 2 and the partition plate 3 form a triangular configuration. The bottom is stably supported, and the top is narrowed with the inclination of the partition plate 3. The thickness of the goods linearly decreases from the bottom end to the top end. The fumigants are discharged from the through holes on the surface of the partition plate 3. Since the upper end of the goods is thin, part of the fumigants can quickly pass through, reducing the residue. At the same time, the triangular space compresses the gas flow path, so that the fumigants form a gas mass with pressure, enhancing the penetration force on the deep gaps of the goods. The restraint block 8 on the outer surface of the stand 6 supports the upper end of the partition plate 3 to ensure the stability of the structure of the pest control area A15.

[0033] The pest control area B5 is formed by the triangular cross-section of the support frame 4 and the partition 3. The support frame 4 releases fumigant through the inclined holes, and the grid structure not only bears the goods but also leaves a passage for gas flow. The space volume at the upper end is larger than that at the lower end, and the fumigant diffused from the pest control area A15 flows along the inclined surface to the narrow lower end under the action of gravity and pressure difference, and converges at the lower end, which is suitable for dense goods. Through the aggregation effect, it ensures that the deep goods are in contact with sufficient fumigant. After the pest control is completed, the fumigant flows along the inclined surface of the support frame 4 and the inclined surface of the upper surface of the goods, and cooperates with the gap between the grids to flow to the hole at the bottom of the device, which reduces the retention and accelerates the discharge of the residual fumigant.

[0034] The negative pressure generated by the exhaust fan in the column 6 extracts the residual fumigant from the pest control area A15 and the pest control area B5 through the small-diameter exhaust pipe A9 and the large-diameter exhaust pipe B10, respectively.

[0035] The high flow rate of the exhaust pipe A9 enhances the suction and penetration of the triangular space of the pest control area A15, and the large flow rate of the exhaust pipe B10 is suitable for the open space of the pest control area B5, realizing efficient circulation. The recovered fumigant is transported to a high place by the column 6, mixed with new fumigant in the air tank 14, and then reused, reducing waste. The horn-shaped exhaust port 7 at the upper end of the column 6 is inclined by 20-30 degrees, which expands the spraying range of the circulating fumigant.

[0036] Further, when the exhaust pipe A9 sucks the fumigant in the pest control area A15, it can guide the fumigant in the area to flow along the partition 3 as a directional flow path. The fumigant that originally penetrates to the lowermost layer of the goods and contacts the surface of the partition 3 under the action of gravity changes its direction of motion from vertical downward to inclined flow along the inclined angle of the partition 3 under the traction of the suction force, forming an inclined penetration power. The change of flow direction can make the fumigant more efficiently penetrate into the gap between the goods in the deep area of the pest control area A15 with thickly accumulated goods, avoiding the penetration blind area formed by the dense accumulation of goods.

[0037] The exhaust pipe B10 is provided with dense air inlet holes on the side close to the column 6. When the exhaust pipe B10 starts to exhaust, the high-speed airflow formed inside the pipe due to the design of the pipe diameter will generate a local negative pressure, which actively absorbs the residual fumigant inside the shell 1 through the air inlet holes, including the fumigant attached to the surface of the goods and floating in the space gap, significantly reducing the probability of residual fumigant in the device and further improving the cleanliness of the pest control process.

[0038] The arc-shaped groove 11 and the rotating shaft 12 at the bend of the duct 2 allow the partition 3 to adjust the inclination angle within 10-60 degrees, which is suitable for different stacking requirements of goods and facilitates the filling of materials to the lower layer. The sealing gasket between the cover plate 13 and the shell 1 and the sealing plug in the through groove ensure the air tightness of the device to prevent the leakage of fumigant. The gas tank 14 supplies fumigant through the inlet pipe, and the shell 1 discharges the internal fumigant through the exhaust pipe before adding goods. The valves of the inlet pipe and the exhaust pipe can be opened and closed as needed. Through these designs, the device realizes efficient penetration, uniform distribution and low residue treatment of fumigant, and is suitable for quarantine and pest control of goods in different stacking forms.
