Description

Technical Field

[0001] The utility model relates to the technical field of insecticide equipment, in particular to a carbon dioxide-nitrogen mixed gas extremely fast insecticide device. Background Art

[0002] Tobacco storage generally uses sealed warehouses to ensure appropriate temperature, humidity, ventilation, and light protection conditions. However, the tobacco leaves inside the warehouses are easily affected by some insect pests, which causes the storage quality of the tobacco leaves to decline, and frequent insecticide treatment is required.

[0003] Currently, the conventional fumigation method using 56% aluminum phosphide tablets is commonly used to control stored tobacco leaf pests. The conventional dosage of aluminum phosphide is 6 to 9 g / m3. This method is simple to operate, but the dosage is large, there may be safety hazards, and there is also the problem of difficult cleaning of drug residues. Compared with conventional fumigation, mixed fumigation improves the dosing process, relocates the source of danger, and greatly reduces the safety risks of the operation process. However, long-term fumigation causes pest resistance to continue to increase, which will lead to fumigation failure, and there are safety and environmental issues, such as gas leakage due to poor sealing. Utility Model Content

[0004] The purpose of the utility model is to provide a carbon dioxide-nitrogen mixed gas extremely fast insecticidal device to solve the problems of the conventional fumigation method and the mixed fumigation method for preventing and controlling stored tobacco leaf pests proposed in the above-mentioned background technology, which result in poor insecticidal effect. In addition, the sealing ring is prone to aging and cracking after long-term use, which affects the sealing effect.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The present application provides a carbon dioxide-nitrogen mixed gas rapid insecticide device, comprising a sealed chamber, wherein the right side of the sealed chamber is connected to a carbon dioxide inlet pipe and a nitrogen inlet pipe, the carbon dioxide inlet pipe is located at the bottom of the sealed chamber, the nitrogen inlet pipe is located above the carbon dioxide inlet pipe, and the top of the sealed chamber is connected to an exhaust structure;

[0007] A sealing groove is provided on the left side of the sealing bin body, a feed port is provided through the sealing groove, and a sealing door adapted to the sealing groove is covered on the sealing groove; a sealing ring is provided on the inner side of the sealing door, and the sealing door is connected to the sealing groove through the sealing ring; a sealing detection device is provided on the sealing door, and the sealing detection device is connected to an alarm.

[0008] As an improvement to the above solution, the sealing detection device includes a clamping seat, a pressure sensor located inside the clamping seat, a telescopic cylinder connected to the clamping seat, the pressure sensor is electrically connected to the alarm, and the alarm is installed on the sealing chamber body;

[0009] The clamping seat is located above the sealing door, the pressure sensor is embedded in the upper part of the clamping seat, the inner side surface of the lower part of the clamping seat is inclined downward, and the telescopic cylinder extends downward to push the clamping seat downward.

[0010] As an improvement to the above solution, the nitrogen inlet pipe is located at one-half to one-third of the height of the sealed chamber.

[0011] As an improvement of the above solution, the exhaust structure includes an exhaust plate located at the top of the sealed warehouse body, and an exhaust pipe provided with an air pump connected to the exhaust plate, and the air pump is fixedly installed on the sealed warehouse body through a base.

[0012] As an improvement of the above solution, one side of the sealing door is movably connected to the sealing warehouse body through a hinge, and the other side of the sealing door is fixed to the sealing warehouse body through a lock, and a handle is also provided on the sealing door.

[0013] As an improvement to the above solution, the telescopic cylinder and the sealing chamber body are fixedly installed via a mounting sleeve, and the telescopic cylinder and the clamping seat are fixedly installed via bolts.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] First, the utility model sets a carbon dioxide inlet pipe, a nitrogen inlet pipe and an exhaust structure. The carbon dioxide inlet pipe is set at the bottom of the right side of the sealed warehouse body, and the nitrogen inlet pipe is set at a height of one-half to two-thirds of the right side of the sealed warehouse body. The density of carbon dioxide is greater than that of air and is deposited at the bottom, while the density of nitrogen is less than that of air, and it will slowly diffuse from the middle to the top. The exhaust structure can quickly extract the gas with high oxygen concentration inside the sealed warehouse body, thereby achieving the purpose of rapid oxygen reduction and extremely fast gas fumigation and insecticide.

[0016] Second, the utility model blocks the gap by fitting the sealing ring on the inner wall of the sealing door with the inner wall of the sealing groove. At this time, the telescopic cylinder is controlled to operate to drive the clamping seat to move downward. After the clamping seat moves downward, it is squeezed with the top of the sealing door through its inclined surface, forming a clamping pressure, so that the sealing door and the sealing groove fit tightly, improving the sealing. After the sealing ring is aged and worn, the thickness gradually decreases, so that the contact area between the sealing door and the sealing groove increases, and the outer wall of the sealing door is gradually aligned with the left side of the sealing warehouse body. When the sealing ring is severely worn, the sealing door completely coincides with the sealing groove and is aligned with the outer wall of the sealing warehouse body. At this time, the clamping seat moves completely downward, and the pressure sensor on the inner wall of the clamping seat begins to contact the outer wall of the sealing door. The pressure generated by the contact is detected by the pressure sensor, and the alarm sounds an alarm to prompt the information that the sealing ring is severely worn and needs to be replaced, thereby ensuring the sealing of the sealing warehouse body and improving the insecticide efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 This embodiment provides a carbon dioxide-nitrogen mixed gas rapid insect killing device, including a sealed chamber body 1, the right side of which is connected to a carbon dioxide inlet pipe 2 and a nitrogen inlet pipe 3, the carbon dioxide inlet pipe 2 is located at the bottom of the sealed chamber body 1, and the nitrogen inlet pipe 3 is located above the carbon dioxide inlet pipe 2, and the nitrogen inlet pipe 3 is located at a height of one-half to two-thirds of the sealed chamber body 1. The density of carbon dioxide is greater than that of air and is deposited at the bottom, while the density of nitrogen is less than that of air, and it will slowly diffuse from the middle to the top.

[0026] The top of sealed chamber 1 is connected to an exhaust structure 400. This exhaust structure 400 includes an exhaust plate 401 located at the top of sealed chamber 1, and an exhaust pipe 402 connected to exhaust plate 401 and equipped with an air pump 403. Air pump 403 is fixed to sealed chamber 1 via a base. Exhaust structure 400 quickly removes the high-oxygen-concentration gas within sealed chamber 1, thereby rapidly reducing oxygen levels and achieving rapid gas fumigation. This design reduces pest control time to within 15 days, reducing the frequency of pest control from once every six months to once a year. Compared to conventional nitrogen pest control, it increases tobacco aging time by 30-45 days per year. This pest control process can effectively reduce pest control costs and fully replace existing phosphine fumigation technology, completely eliminating safety and environmental risks.

[0027] During use, the carbon dioxide inlet pipe 2 is arranged at the bottom of the right side of the sealed warehouse body 1, and the nitrogen inlet pipe 3 is arranged at a position between one-half and two-thirds of the right side of the sealed warehouse body 1. The density of carbon dioxide is greater than that of air and is deposited at the bottom, while the density of nitrogen is less than that of air, so it will slowly diffuse from the middle to the top. The exhaust structure 400 can quickly extract the gas with high oxygen concentration inside the sealed warehouse body 1, thereby achieving the purpose of rapid oxygen reduction and extremely fast gas fumigation and insecticide.

[0028] A sealing groove 4 is formed on the left side of the sealed bin body 1, through which a feed port 5 is formed. Tobacco leaves are stored in the sealed bin body 1 through the feed port 5. A sealing door 6 is fitted over the sealing groove 4. A sealing ring 7 is glued to the inside of the sealing door 6, which is connected to the sealing groove 4 via the sealing ring 7. A sealing detection device 8 is provided on the sealing door 6, which is connected to an alarm 9.

[0029] The sealing detection device 8 includes a clamping seat 801 and a pressure sensor 802 located inside the clamping seat 801. The clamping seat 801 is installed above the sealing door 6. The top of the clamping seat 801 is connected to a telescopic cylinder 803. The pressure sensor 802 is electrically connected to the alarm 9, and the alarm 9 is installed at the top of the sealing chamber body 1.

[0030] The clamping seat 801 is located above the sealing door 6, and the pressure sensor 802 is embedded in the upper part of the clamping seat 801. The inner side surface of the lower part of the clamping seat 801 is inclined downward to form an inclined surface 804. The telescopic cylinder 803 extends downward to push the clamping seat 801 to abut against the outer side of the sealing door 6, thereby improving the sealing effect.

[0031] When the sealing door 6 is engaged in the sealing groove 4, the sealing ring 7 on the inner wall of the sealing door 6 fits with the inner wall of the sealing groove 4 to block the gap. At this time, the telescopic cylinder 803 is controlled to extend downward to push the clamping seat 801 to move downward. The inclined surface 804 of the clamping seat 801 is squeezed with the top of the sealing door 6 to form a clamping pressure, so that the sealing door 6 fits tightly with the sealing groove 4 to improve the sealing performance. After the sealing ring 7 ages and wears, its thickness gradually decreases, which increases the contact area between the sealing door 6 and the sealing groove 4, and the outer wall of the sealing door 6 and the sealing groove 4 are The left side of the bin body 1 is gradually aligned. When the sealing ring 7 is severely worn, the sealing door 6 completely overlaps with the sealing groove 4 and is aligned with the outer wall of the sealed bin body 1. At this time, the clamping seat 801 is completely moved down, and the inner wall of its upper part contacts the outer wall of the sealing door 6. At the same time, the pressure sensor 802 on the inner wall of the clamping seat 801 begins to contact the outer wall of the sealing door 6. The pressure generated by the contact is detected by the pressure sensor 802, and the pressure sensor 802 controls the alarm 9 through the PLC controller to sound an alarm, indicating that the sealing ring 7 is severely worn and needs to be replaced.

[0032] One side of the sealing door 6 is movably connected to the sealing chamber body 1 by a hinge. When the sealing door 6 is closed, the other side of the sealing door 6 is fixed to the sealing chamber body 1 by a lock 10. A handle 11 is also provided on the sealing door 6 to facilitate the opening and closing of the sealing door 6.

[0033] The telescopic cylinder 803 is fixedly mounted to the sealing chamber body 1 via a mounting sleeve, and the telescopic cylinder 803 is fixedly mounted to the clamping seat 801 via bolts.
