Description

TECHNICAL FIELD

[0001] The utility model belongs to the grain storage fumigation equipment technical field, concretely relates to a kind of grain storehouse circulation fumigation system outside warehouse medicine supplement pendant. BACKGROUND

[0002] As the key facility of grain depot insecticide, the importance of circulation fumigation is self-evident. It is through the medicine of warehouse gas generator, and with the help of the circulation pipeline system in the warehouse, the volatile gas of medicine is evenly dispersed to each layer of the grain storehouse, so as to effectively kill insects. This technology not only improves the diffusion speed of toxic gas in grain pile, makes distribution more uniform, but also significantly reduces the labor intensity of medicine, and reduces the time of personnel exposure to toxic gas, ensures good insecticide effect.

[0003] At present, circulation fumigation technology has been widely recognized in the application of newly-built high and large flat warehouse, but the current circulation fumigation technology still has the following technical problems:

[0004] In the design specification of modern high-standard grain storehouse in national standard, the structure of warehouse gas generator usually includes circulation fan and gas generating device connected with circulation fan pipeline. These gas generating devices are mainly used to generate phosphine fumigation gas (PH3), and transport these gases into the warehouse through pipeline, gas distribution valve and circulation fan. However, the commonly used gas generating device in the market, such as CFY8-IV / CFY8-V type phosphine gas generator, usually costs about 50W, and can only support single warehouse operation. For enterprises, there is a problem of high equipment cost, which not only increases the operation cost of grain depot, but also may cause certain pressure on the financial situation of grain depot, directly affects the storage benefit ratio, and further affects the safety of grain storage.

[0005] More seriously, these gas generating devices may have safety hazards in use. Phosphine is slightly heavier than air, and usually aluminum phosphide tablets or medicine bag is placed on the surface of grain in the warehouse, which slowly releases highly toxic phosphine gas by reacting with moisture in the air. When high concentration is gathered, there is a certain risk. There are many reports of grain fumigation explosion accidents on the Internet, which can be summarized as follows:

[0006] Improper placement of fumigant in the warehouse may cause fire / explosion;

[0007] Improper handling of fumigant residue collection may cause poisoning and fire or even explosion.

Obviously, the described embodiments are only part of the embodiments of the present application and are not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of the present application.

[0031] Embodiment 1

[0032] This embodiment introduces a newly designed medicine supplementing pendant for the ring flow fumigation system outside the granary, aiming to optimize and simplify the process of supplementing the concentration of medicaments in the fumigation process of the granary. Please refer to ​ The medicine supplementing pendant specifically includes the following key components:

[0033] Supporting rod assembly 1: This assembly is carefully laid out at the top inside the box 2 of the ring flow fan 3. The highlight of its design is that the length of the supporting rod can be flexibly adjusted according to actual installation needs, ensuring that the two ends of the supporting rod can closely fit the inner wall of the box 2 during installation, achieving stable support. Such a design not only enhances the stability of the pendant, but also improves the convenience and adaptability of installation.

[0034] Medicine bag pendant 4: At least one is equipped to hold medicaments. The supporting rod assembly 1 is ingeniously provided with multiple hanging holes 18, facilitating easy hanging of the medicine bag pendant 4. The medicine bag pendant 4 is filled with volatile medicaments that can undergo natural deliquescence under certain conditions, fully releasing PH3 phosphine gas. In this embodiment, the selected volatile medicament is mainly aluminum phosphide, which can be in the form of powder or solid to meet the use needs in different scenarios.

[0035] The working principle of the medicine supplementing pendant outside the granary is very efficient and environmentally friendly. When the aluminum phosphide medicament in the medicine bag pendant 4 undergoes natural deliquescence, it will release PH3 gas. These gases will enter the inside of the grain pile along the gas path of the ring flow pipeline under the action of the ring flow fan, supplementing the PH3 gas concentration inside the grain pile. This process not only prolongs the time of effective PH3 in the fumigated grain pile, but also greatly simplifies the process of secondary medicine supplementing in the granary.

[0036] Compared with the traditional gas generating device, the medicine replenishing pendant outside the warehouse provided by the embodiment has significant advantages. It is not only convenient to install and low in cost, but also makes full use of the space inside the lower air duct box 2, avoiding complex and expensive equipment investment. More importantly, there is no risk of personnel safety in the use of the pendant, effectively ensuring the safety of the operating personnel.

[0037] In summary, the medicine replenishing pendant outside the warehouse of the grain warehouse circulating fumigation system in the embodiment provides a new solution for the replenishment of the concentration of the medicine in the fumigation process of the grain warehouse with its unique design concept and excellent practical performance.

[0038] Embodiment 2

[0039] The embodiment further elaborates the specific implementation of the support rod assembly 1 in detail, aiming to provide a more comprehensive and in-depth understanding. Please refer to ​ The support rod assembly 1 is composed of symmetrically arranged support rod I 5 and support rod II 6. Both of the two support rods are hollow pipe structures, which are designed ingeniously to reduce the overall weight. The two ends of the support rod I 5 and the support rod II 6 are ingeniously provided with internal threads, which enables them to achieve stable threaded connection with other components.

[0040] Between the support rod I 5 and the support rod II 6, a length adjusting piece 7 is connected. This length adjusting piece 7 not only has a compact structure, but also has powerful functions. It allows users to adjust the distance between the two support rods according to actual needs, thereby achieving flexible adjustment of the overall length of the support rod assembly 1. This design enables the support rod assembly 1 to adapt to different sizes of the box 2, greatly enhancing its practicality and flexibility.

[0041] On the other end of the support rod I 5 and the support rod II 6 away from the length adjusting piece 7, there is a non-slip foot prop 8 threaded respectively. These non-slip foot props 8 not only can effectively prevent the support rod from sliding inside the box 2, but also can realize the close fitting of the inner wall of the box 2 through its unique structure. The contact surface of the non-slip foot prop 8 and the box 2 is specially provided with a layer of silica gel. This layer of silica gel not only has good wear resistance and corrosion resistance, but also can provide excellent anti-skid effect, thereby further enhancing the fixing effect of the support rod assembly 1.

[0042] Further, please refer to ​The length adjusting member 7 includes a knurled nut disc 9 and threaded rods I 10 and II 11 fixed on both sides of the knurled nut disc 9, respectively. The two threaded rods are coaxial with the knurled nut disc 9, and their thread directions are arranged in opposite directions. This design enables the threaded rods I 10 and II 11 to simultaneously realize relative or opposite movement when the knurled nut disc 9 rotates, thereby driving the support rods I 5 and II 6 to elongate or shorten accordingly. This adjustment method is not only simple and easy to understand, but also convenient to operate, greatly improving work efficiency.

[0043] Further, the structure of the anti-skid foot support 8 includes a base 12 and a connecting rod 13. The connecting rod 13 is provided with external threads, one end of which is threadedly connected with the support rod I 5 or II 6, and the other end is perpendicular to the axis of the base 12 and fixedly connected with the base 12. This design enables the anti-skid foot support 8 to be firmly installed on the support rod and to realize close fitting to the inner wall of the box 2 by adjusting the length of the connecting rod 13 extending outward. This fine-tuning pre-tightening method not only improves the stability of the support rod assembly 1, but also ensures its reliable use in various complex environments.

[0044] In addition, the support rods I 5 and II 6 are also provided with a plurality of hanging holes 18 at equal intervals along the axial direction. The design of these hanging holes 18 enables users to select the number and position of the medicine bag hanger 4 according to actual needs, thereby realizing precise dispensing and flexible management of the fumigating agent. This design not only improves the efficiency of fumigating secondary medicine, but also greatly enhances the flexibility and customizability of the system.

[0045] Example 3

[0046] This embodiment introduces the specific implementation details of the medicine bag hanger 4, aiming to provide users with more detailed and practical information. As a key component in the secondary medicine supplement system for the grain warehouse circulating fumigation outside the warehouse, the design of the medicine bag hanger 4 is directly related to the fumigation effect and the utilization rate of the agent.

[0047] Please refer to ​ The medicine bag hanger 4 is mainly composed of a hook 14 and a medicine bag 15. The hook 14 is ingeniously arranged at the top of the medicine bag 15, which not only facilitates users to quickly and stably connect the medicine bag hanger 4 with the support rod, but also ensures the stability and reliability of the medicine bag hanger 4 during the fumigation process. At the same time, the material and shape of the hook 14 have also been carefully selected and optimized to ensure that it can withstand the weight of the medicine bag 15 and its internal agent, and maintain good durability and corrosion resistance during long-term use.

[0048] The design of the fumigating agent bag 15 as a container for loading fumigating agent is also crucial. The fumigating agent bag 15 is carefully provided with a plurality of volatile micro-holes 16. The size, shape and distribution of these micro-holes are strictly calculated and tested to ensure that the fumigating agent can be uniformly and stably volatilized and fully mixed with the air in the warehouse, thereby achieving the best fumigation effect. At the same time, the design of the volatile micro-holes 16 can effectively prevent excessive volatilization and waste of the fumigating agent, improve the utilization rate of the fumigating agent and the economy of fumigation, and the efficient recycling of fumigating agent residues is environmentally friendly.

[0049] In order to further improve the fumigation effect and the utilization rate of the fumigating agent, the embodiment also proposes an innovative structure of the fumigating agent bag 15. The fumigating agent bag 15 is composed of at least one bag unit 17, which is arranged in a rectangular array along the vertical direction. The adjacent bag units 17 are connected by firm fixing connectors to ensure the stability and integrity of the entire fumigating agent bag 15 during fumigation. This design not only enables the fumigating agent volatilization gas to be more uniformly distributed in the warehouse, but also improves the volatilization efficiency of the fumigating agent and the fumigation effect.

[0050] In addition, the material of the fumigating agent bag 15 is also carefully selected. It is made of a material with good air permeability and corrosion resistance to ensure that the fumigating agent can be smoothly volatilized and prevent the fumigating agent bag 15 from being damaged or deformed during long-term use.
