Description

Technical Field

[0001] The invention relates to the technical field of stored-grain pest control, in particular to a cold-smoking fumigation tank. Background Art

[0002] During the storage of bulk grain, storage pests are an important factor endangering the safety of bulk grain. Therefore, to ensure the safety of bulk grain storage, it is necessary to do a good job in preventing and controlling storage pests.

[0003] Traditional pest control methods include trapping pests with traps, which are only suitable for pest control when the number of pests is small; another method is to decompose solid aerosols to produce fumigant gas, which quickly maintains a fumigation environment of a certain concentration in the warehouse, thereby killing the pests.

[0004] Existing solid aerosols, such as the "fumigant insecticide, fumigation insecticide device, and insecticide method" disclosed in Chinese patent CN102754644A, are solid as a whole and include a non-self-reactive exothermic matrix, in which insecticide components are mixed. When used, the fumigant insecticide is heated to 150-450°C, and the matrix and insecticide form smoke that evaporates throughout the space.

[0005] The existing fumigant insecticide has the following problems: 1. It lacks a corresponding reaction device and cannot effectively gather and disperse the smoke; 2. When the fumigant insecticide is used in a granary, since the granary is a dusty space, an open flame cannot be used to heat the fumigant insecticide. Summary of the invention

[0006] The object of the present invention is to provide a cold-smoking fumigation pot which can facilitate the reaction of fumigation insecticide.

[0007] In order to solve the above technical problems, a technical solution of a cold-smoking fumigation tank in the present invention is as follows: A cold-smoking fumigation tank comprises a fumigant insecticide and a tank body. The fumigant insecticide is arranged at the bottom of the inner cavity of the tank body, a cigarette lighting hole is provided in the middle of the fumigant insecticide, a reaction chamber is provided on the upper side of the fumigant insecticide in the inner cavity of the tank body, a spring is provided in the reaction chamber, the upper end of the spring cooperates with the top of the tank body, the lower end of the spring cooperates with the upper end of the fumigant insecticide, and a tank body smoke outlet is provided on the top of the tank body.

[0008] Furthermore, the cigarette ignition hole is arranged at the center of the fumigant, and the cigarette ignition hole penetrates the fumigant in the up-down direction.

[0009] Furthermore, a top inverted edge is provided on the top of the tank body, and the smoke outlet of the tank body is composed of a space surrounded by the top inverted edge. A spring top plate is provided between the top of the spring and the top inverted edge, and a plurality of top plate smoke outlet holes arranged at intervals along the circumferential direction are provided on the spring top plate, and the top plate smoke outlet holes are communicated with the smoke outlet of the tank body.

[0010] Furthermore, an intermediate plate is arranged between the spring and the fumigant, a middle plate perforation connecting the cigarette ignition hole and the reaction chamber is arranged in the middle of the intermediate plate, a lower positioning plate extending downward and located at the periphery of the fumigant is arranged on the periphery of the intermediate plate, and an upper positioning plate extending upward and located at the periphery of the spring is arranged on the periphery of the intermediate plate.

[0011] Furthermore, there are multiple lower positioning plates, which are spaced apart circumferentially along the middle plate; there are multiple upper positioning plates, which are spaced apart circumferentially along the middle plate, and each upper positioning plate is staggered with the corresponding lower positioning plate in the circumferential direction of the middle plate.

[0012] Furthermore, it also includes an igniter, which includes an ignition cable, the upper end of the ignition cable is connected to a power connector, the lower end of the ignition cable is electrically connected to a resistance wire, the resistance wire is wrapped with an ignition wire skin, gunpowder is arranged between the ignition wire skin and the resistance wire, and the ignition wire skin extends into the cigarette lighting hole.

[0013] Furthermore, at least two positioning wire skins spaced apart along the circumferential direction are fixed on the ignition cable, and the outer ends of the positioning wire skins are clamped between the middle plate and the fumigant insecticide, and the positioning wire skins perforate the middle plate to separate it into at least two smoke passages.

[0014] The beneficial effects of the present invention are as follows: the spring plays a role in limiting the upward and downward movement of the fumigant insecticide, thereby preventing the fumigant insecticide from shaking up and down during transportation and colliding with the tank body, thereby causing the fumigant insecticide to break. When used on site, the cigarette ignition hole in the middle of the fumigant insecticide is heated, and the fumigant insecticide forms smoke that first enters the reaction chamber. The function of the reaction chamber is to gather and pressurize the smoke, so that when the smoke is discharged through the smoke outlet of the tank body, it has a certain initial velocity, so that the smoke can quickly climb to the top of the space, forming a mushroom cloud-shaped volatilized smoke, thereby ensuring the insecticidal effect.

[0015] Furthermore, when faced with a dusty space such as a granary, the power connector of the ignition cable is connected to a power bank, the resistor wire is heated, the gunpowder is ignited, and the heating reaction of the fumigant insecticide is completed in the cigarette ignition hole, avoiding the occurrence of open flames on the outside of the tank and the possibility of safety hazards.

[0017] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0019] An embodiment of a cold-smoking fumigation tank of the present invention is as follows: Figures 1 to 8 As shown: The tank body 1 includes a tank body 1, and two fumigants 13 are arranged in sequence in the up-down direction at the bottom of the inner cavity of the tank body 1. The fumigant 13 includes a matrix mixed with an insecticide component and a foaming agent. The insecticide component in this embodiment is cypermethrin. The fumigant is a hollow cylindrical block as a whole, and the inner hole of the fumigant constitutes a cigarette lighting hole 14.

[0020] The inner cavity of the tank body and the upper side of the fumigant are reaction chambers 10, in which springs 2 are arranged, the inner hole of which is larger than the aperture of the cigarette-lighting hole, the upper end of the spring cooperates with the top of the tank body, the lower end of the spring cooperates with the upper end of the fumigant, and a tank smoke outlet 5 is arranged on the top of the tank body.

[0021] In this embodiment, the cigarette ignition hole 14 is arranged at the center of the fumigant, and the cigarette ignition hole penetrates the fumigant in the vertical direction. The top of the tank body is provided with a top inverted edge 4, and the tank body smoke outlet 5 is formed by the space surrounded by the top inverted edge. A spring top plate 3 is arranged between the top of the spring and the top inverted edge. The spring top plate 3 is provided with a plurality of top plate smoke outlet holes 9 arranged at intervals along the circumferential direction. The top plate smoke outlet holes 9 are connected to the tank body smoke outlet 5. The plurality of top smoke outlet holes help to make the smoke outlet more uniform.

[0022] An intermediate plate 12 is provided between the spring and the fumigant, and an intermediate plate through hole 18 connecting the cigarette ignition hole and the reaction chamber is provided in the middle of the intermediate plate 12. A lower positioning plate 16 extending downward and located at the outer periphery of the fumigant is provided on the outer periphery of the intermediate plate, and an upper positioning plate 11 extending upward and located at the outer periphery of the spring is provided on the outer periphery of the intermediate plate. In this embodiment, there are three lower positioning plates 16, which are arranged at intervals along the circumference of the intermediate plate, and the three lower positioning plates are integrally formed with the intermediate plate, and the upper end of the fumigant is positioned and matched with the three lower positioning plates; there are three upper positioning plates 11, which are arranged at intervals along the circumference of the intermediate plate, and the three upper positioning plates are integrally formed with the intermediate plate, and the lower end of the spring is positioned and matched with the three upper positioning plates, and each upper positioning plate is staggered with the corresponding lower positioning plate in the circumferential direction of the intermediate plate.

[0023] The cold-smoking fumigation tank also includes an igniter 8, which includes an ignition cable 6, the upper end of which is connected to a power connector 7, the lower end of which is electrically connected to a resistance wire 19, the outer periphery of which is wrapped with an ignition wire skin 15, gunpowder 20 is arranged between the ignition wire skin 15 and the resistance wire, the ignition wire skin 15 extends into the lower end of the cigarette-lighting hole 14, and there is nano powder 21 between the gunpowder and the ignition wire skin, and the nano powder 21 helps to miniaturize the smoke particles when the fumigant insecticide is dispersed. In other embodiments of the present invention, the nano powder 21 may not be provided.

[0024] Two circumferentially spaced positioning wire skins 17 are fixed to the ignition cable. The width of the positioning wire skins is 5 mm to 15 mm. The outer ends of the positioning wire skins 17 are clamped between the middle plate and the fumigant. The positioning wire skins perforate the middle plate to separate it into two smoke passages.

[0025] The spring 2 plays a role in positioning the fumigant insecticide to prevent the fumigant insecticide from shaking during transportation and breaking. At the same time, the spring can also use its own elasticity to adapt to the height of the fumigant insecticide 13. Because different space sizes require different numbers or sizes of fumigants, the spring can use its own elasticity to match fumigants of different heights; the positioning wire skin can locate the position and height of the ignition wire skin. When the power connector is electrically connected to the power bank, the resistance wire heats up and ignites the gunpowder. The gunpowder heats the fumigant insecticide to the volatilization temperature. The positioning wire skin also has another function, which is to reduce the cross-sectional area of ​​the middle plate perforation that can pass smoke in the early stage of the fumigant insecticide reaction. This can reduce the amount of oxygen entering the cigarette ignition hole from top to bottom, and avoid excessive oxygen content in the cigarette ignition hole in the early stage of cigarette ignition. If the oxygen content is too high, the fumigant insecticide will not be in a state of emitting smoke particles, but in a ignited state, which is very dangerous. As the fumigant insecticide continues to evaporate, it evaporates from bottom to top, and the positioning wire skin shrinks or breaks due to the high temperature baking effect. At this time, the cross-sectional area of ​​the middle plate perforation that can pass smoke increases, and more oxygen enters the cigarette hole from top to bottom to ensure the fumigant insecticide's volatilization effect; after the fumigant insecticide is gathered and pressurized in the reaction chamber, it flows upward evenly through the smoke outlet holes on the top plate of the spring, and quickly forms Figure 8 In the mushroom cloud state shown, the smoke spreads in the sky and covers the entire roof of the warehouse, and then sinks naturally, achieving full coverage of the insecticide ingredients in the warehouse, thereby ensuring the insecticide effect.
