Description

Technical Field

[0001] The utility model belongs to the technical field of grain storage, and more specifically, particularly relates to a device for applying a grain storage protective agent. Background Art

[0002] At present, with the improvement of people's environmental awareness and the high attention paid to healthy consumption, highly toxic fumigant insecticides with great environmental impact are gradually withdrawing from the grain storage pest control market, and low-toxic and high-efficiency grain storage protective agents are becoming more and more widely used. There are generally two ways to use grain storage protective agents: full warehouse application and surface application. Since grain storage pests mainly occur in the upper layer of grain piles, and surface application is better than full warehouse application in terms of dosage, cost and ease of use, surface application is the most widely used method.

[0003] Based on the above, the inventors found that the following problems exist: the traditional protective agent application device cannot form an aerosol, the electric sprayer relies on a motor to pressurize the emulsifiable protective agent, the pressure is relatively low, and the general working pressure is 0.0-2.5MPa, which has a greater impact on the relative humidity of the space in the closed warehouse. The electric sprayer generally has a capacity of about 16L and a water content of 15L. When the local spraying volume is large, the moisture content of the grain is significantly increased, which endangers the safety of grain storage, and a positive pressure air respirator cannot be worn at the same time. A protective mask is generally worn during the application process, and effective safety protection cannot be carried out, which poses a safety hazard.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a grain storage protective agent application device is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a grain storage protective agent application device to solve the current problems that aerosol cannot be formed, the moisture content of grain is significantly increased when the local spraying amount is large, which endangers the safety of grain storage, and a positive pressure air respirator cannot be worn at the same time.

[0006] The utility model provides a device for applying a grain storage protective agent, which is achieved by the following specific technical means:

[0007] A device for applying a grain storage protective agent comprises a gas cylinder, wherein an air outlet joint is arranged on the top of the gas cylinder, one end of the air outlet joint is sealedly connected to a connector, one side of the connector is penetrated by a second conduit sealedly connected, the other side of the connector is penetrated by a first conduit and a breathing tube, one end of the first conduit is fixed with a pressure gauge, one end of the second conduit is sealedly fixed with a handle, one end of the handle is provided with a nozzle, the bottom of one side of the handle is threadedly connected to a capacity pot, the middle of the handle is provided with a spray switch, and the top of the other end of the handle is provided with a liquid valve and an air valve.

[0008] Furthermore, the interior of the handle is hollow, and the second conduit and the nozzle are interconnected.

[0009] Furthermore, the gas cylinder is a positive pressure air respirator with a pressure of 30 MPa inside the cylinder, the nozzle diameter is 1.0 mm, and the capacity of the capacity pot is 1 L.

[0010] Furthermore, a breathing mask is fixed to one end of the breathing tube, and a headband is fixed to one side of the breathing mask.

[0011] Furthermore, a bottom pocket is sleeved on the bottom of the gas cylinder, a back rod is fixed on one side of the bottom pocket, and straps are fixed on the top and middle of the back rod.

[0012] Furthermore, the two straps are wrapped around the outer wall of the gas cylinder, and shoulder straps are fixed on both sides of the back rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the gas cylinder is filled to 30MPa of the positive pressure air respirator, and then the air outlet joint is opened, and the compressed air enters the second conduit through the connector, and the high-pressure air enters the grip from the second conduit, and the liquid in the capacity pot is atomized by the gas of the gas cylinder. The greater the gas valve adjustment, the better the atomization degree, and the greater the liquid valve adjustment, the faster the application speed. The emulsifiable protective agent mixed with 10% water is added to the capacity pot. The emulsifiable protective agent has a large viscosity, and a small amount of water is added to dilute it, which is more conducive to atomization and formation of aerosol, thereby achieving a better atomization effect.

[0015] 2. In the utility model, personal safety protection and the spraying device are integrated into one, and the safety protection level is higher. A breathing mask must be worn during the spraying process. Safety protection and spraying are synchronized, protection is more convenient, and the protection level is higher.

[0028] Among them, the gas cylinder 5 is a positive pressure air respirator with an internal pressure of 30MPa, the nozzle 16 has a diameter of 1.0mm, and the capacity of the capacity pot 15 is 1L. The internal pressure of the gas cylinder can be filled to 30MPa through external pressure charging.

[0032] Among them, the following table shows the specific experimental conditions when the device is used.

[0033]

[0034]

[0035] Experimental data using the device: Basic warehouse conditions: warehouse capacity 5,800 tons, central reserve wheat 5,800 tons, grain loading height 6.37 meters, grain pile volume 7018m 3 , space volume 5626m 3 . Pests: 1 head / ㎡ (moth larvae and adults).

[0036] Application process: three cylinders of gas were used (cylinder model: FQL157-6.8-B; working pressure: 30 MPa; medium: compressed air; volume: 6.8 L). After the application was completed at 10:29 am, the doors and windows were closed and a mixture of 2200 ml of methyl pirimiphos emulsifiable concentrate (active ingredient 55%) and water was atomized. The application time in the warehouse was 10 minutes at a rate of 220 ml / min. After the application, there were obvious atomized drug attachments on the respirator and mask.

[0037] Pesticide application monitoring: The on-site inspection and the surveillance video in the warehouse recorded the entire process of the atomization process. It was found that there was obvious fog of the protective agent. The protective personnel wearing protective masks were stimulated by the smell of the medicine and coughed violently (the instructions of the medicine require wearing protective masks) and wore respirators for protection. After the atomization was completed, the video surveillance found that at 10:32, the warehouse was covered with atomized EC protective agent, like a heavy fog. Subsequently, at 11:24, 12:24, 13:18, 14:20, 15:19, 16:22, and 17:17, the warehouse video found that there was EC protective agent mist floating in the warehouse, and the fog in the warehouse gradually faded as time went on. At 17:17, only extremely weak fog could be found, which could not be found without careful comparison of the picture. Check the grain one week later: the grain temperature was normal, the grain condition was stable, and no pest activity was found. The experimental conclusion: The device has a significant effect on the atomization of EC protective agent, and aerosol has been formed, which lasts for about 6 hours. Due to the micro-airflow in the warehouse, the aerosol can be evenly distributed on the grain surface, warehouse wall and warehouse roof, playing the role of "contact killing, fumigation and stomach killing" of pests. The protection effect is good this time. In view of the experimental effect of this warehouse, it is recommended that it can be used for grain surface protection agent application and empty warehouse disinfection, and the effect is better than traditional sprayers.

[0038] Experimental data 2 using the device: 6,000 tons of storage capacity, 5,700 tons of imported regulated corn reserves, 4.66 meters of grain pile height, and 7,500 m3 of grain pile volume in the warehouse 3 , space volume 6950m 3 , 1 pest / ㎡ (moth larvae and adults).

[0039] Experimental process: Protective equipment: positive pressure air respirator, emulsifiable concentrate protective agent application device, application began at 9:05 am, using 1.5 liters of methyl pirimiphos emulsifiable concentrate with 300 ml of water, a total of 3 cylinders of gas, application time in the warehouse for 8 minutes, application rate of 225 ml / min, after the application, there were obvious atomized agent attachments on the respirator and mask.

[0040] Pesticide monitoring: Since the warehouse had no monitoring equipment, the methyl pyriphos emulsifiable concentrate was well atomized in the warehouse after the pesticide was applied, and an aerosol was formed in the warehouse. Visually, the warehouse looked like a thick fog. A week later, people wore protective masks to enter the warehouse to check the grain. Due to the strong smell of methyl pyriphos, people could not enter. Later, they wore positive pressure air respirators to enter the warehouse for inspection. The grain situation was stable and no abnormalities were found. Two days later, they wore positive pressure air respirators and opened windows to diffuse the air, and no pest activity was found.

[0041] Experimental conclusion: The device has obvious atomization effect on emulsifiable protective agent and has formed aerosol. The protective effect is good this time.

[0042] Suggestion: This device can be used for spraying protective agents on imported regulated reserve corn

[0043] The specific usage and function of this embodiment are as follows:

[0044] In the utility model, firstly, the gas cylinder 5 is filled to a 30MPa positive pressure air respirator, and then the pressure reducing valve outlet joint 6 is opened, and the compressed air enters the second conduit 13 through the connector 7, and the high-pressure air enters the grip 14 from the second conduit 13, and the liquid in the capacity pot 15 is atomized by the gas of the gas cylinder 5, and a part of it forms an "aerosol" and is suspended in the space after being sprayed on the grain surface (the actual warehouse experiment is suspended in the warehouse space for about 5-7 hours), and the size of the flow rate and the degree of atomization of the emulsifiable concentrate protective agent are adjusted by two regulating valves behind the grip 14. The larger the adjustment of the gas valve 18, the better the atomization degree, the larger the adjustment of the liquid valve 17, the faster the application speed, and the smaller the adjustment of the liquid valve 17, the better the atomization degree. The emulsifiable concentrate protective agent mixed with 10% water is added into the capacity pot 15. The viscosity of the emulsifiable concentrate is relatively large, and a small amount of water is added to dilute it, which is more conducive to atomization and aerosol formation, thereby accelerating the application speed.
