Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material warehouse equipment, specifically a nitrogen insecticide machine for medicinal material warehouses. Background Technology

[0002] In medicinal herb warehouses, medicinal herbs are easily affected by pests during storage, leading to a decline in quality and even loss of medicinal value. Currently, common pest control methods include chemical fumigation and physical methods. While chemical fumigation is effective, it can leave harmful residues on the herbs, posing a potential threat to human health. Physical methods, such as high temperature and freezing, are complex to operate and may also affect the quality of the herbs. Nitrogen gas pest control, as a green and environmentally friendly method, is gradually being adopted. It utilizes the inertness of nitrogen to reduce the oxygen content in the warehouse, causing pests to die from lack of oxygen and avoiding the problem of chemical residues.

[0003] Existing nitrogen insecticide equipment has some shortcomings in use. For example, the automation level of nitrogen insecticide equipment is low, requiring frequent manual operation. At the same time, the medicinal materials in the medicine warehouse are generally placed on shelves, and the density of nitrogen is lower than that of air. The nitrogen inlet is usually fixed at the top of the medicine warehouse. After the nitrogen is sprayed out, it first floats at the top of the medicine warehouse and gradually spreads downward as the nitrogen concentration increases. It cannot quickly kill insects at the place where the medicinal materials are placed, thus reducing the insecticidal effect.

[0028] Example:

[0029] Please see Figure 1-5 A nitrogen insecticide for medicinal herb storage includes a chamber 1 and a nitrogen storage tank 2. A controller 3 is fixedly installed on the surface of the chamber 1. A nitrogen filling pipe 4 is fixedly connected to the outlet end of the controller 3. One end of the nitrogen filling pipe 4 extends into the interior of the chamber 1. A flow control valve 5 is fixedly installed on the nitrogen filling pipe 4. A connecting mechanism 6 is provided at the top of the inner cavity of the chamber 1 relative to the nitrogen filling pipe 4. An outlet mechanism 7 is provided at the bottom of the connecting mechanism 6. An adjustment mechanism 8 is provided at the connection between the connecting mechanism 6 and the outlet mechanism 7. A return gas mechanism 9 is provided at the bottom of the chamber 1. An air pump 10 is installed on the chamber 1. Multiple oxygen concentration sensors 11 are equidistantly arranged on the inner wall of the chamber 1. The nitrogen storage tank 2 is used to store nitrogen and is connected to the interior of the chamber 1 through the nitrogen filling pipe 4. A flow control valve 5 is provided on the nitrogen filling pipe 4. A control valve 5 is used to control the flow rate of nitrogen gas. A connecting mechanism 6 is installed on the top inside the medicinal herb warehouse and is connected to the nitrogen filling pipe 4 to directly apply nitrogen gas to the medicinal herbs on the shelves for rapid insecticidal treatment. An oxygen concentration sensor 11 is installed at different locations inside the chamber 1 to detect the oxygen concentration in the chamber 1 in real time and transmit the detection signal to the controller 3. The controller 3 is electrically connected to the oxygen concentration sensor 11, the flow control valve 5, and the air pump 10. It receives the signal from the oxygen concentration sensor 11 and controls the opening of the flow control valve 5 and the working state of the air pump 10 according to the preset oxygen concentration value. The air pump 10 is connected to the nitrogen filling pipe 4 to provide power for nitrogen gas filling, thereby automating the operation of the equipment and avoiding frequent manual operation.

The top of the connecting plate 61 has a fixing groove 62 that is fixedly connected to the nitrogen filling pipe 4. The bottom of the inner cavity of the fixing groove 62 has a cavity groove 63, and the bottom of the cavity groove 63 has multiple air outlet grooves 64. Nitrogen gas is transported to the cavity groove 63 through the nitrogen filling pipe 4, and then quickly transported to various positions in the chamber 1 through the multiple air outlet grooves 64, so as to avoid uneven distribution of nitrogen gas in the chamber 1.

[0031] Furthermore, the air outlet mechanism 7 includes a first air outlet plate 71 fixedly sleeved on the inner wall of the air outlet groove 64, and a second air outlet plate 72 movably sleeved on the inner wall of the first air outlet plate 71.

The limiting frame 74 is fixedly connected to the top of the second air outlet plate 72. By sliding the second air outlet plate 72 within the first air outlet plate 71, the height of the air outlet mechanism 7 can be adjusted, thereby allowing direct insecticidal treatment of the medicinal materials on the shelf. By setting the limiting groove 73 and the limiting frame 74, the first air outlet plate 71 and the second air outlet plate 72 can be prevented from detaching from each other.

[0032] The limiting frame 74 has a sealing ring 75 embedded in its surface, and springs 76 are fixedly connected to the four corners of the top of the limiting frame 74. One end of the spring 76 is fixedly connected to the top of the inner cavity of the limiting groove 73. By setting the sealing ring 75, the sealing between the first air outlet plate 71 and the second air outlet plate 72 can be increased. By setting the spring 76, the stability between the first air outlet plate 71 and the second air outlet plate 72 can be increased, and their shaking can be prevented.

A linkage groove 83 is formed on the top of the linkage plate 82 relative to the position of the second air outlet plate 72. The second air outlet plate 72 is fixedly sleeved inside the linkage groove 83. By driving the linkage plate 82 downward by the electric actuator 81, the limiting groove 73 installed in the linkage groove 83 can be moved downward synchronously. The electric actuator 81 and the controller 3 are electrically connected.

[0034] It should also be noted that the return gas mechanism 9 includes a return gas pipe 91 fixedly connected to the bottom of the chamber 1, and a return gas valve 92 installed on the return gas pipe 91. One end of the return gas pipe 91 is fixedly connected to the gas inlet end of the nitrogen storage tank 2; the end of the return gas pipe 91 away from the nitrogen storage tank 2 is connected to the inner cavity of the chamber 1; the return gas pipe 91 is equipped with a return gas valve 92 and a gas purification device. The gas purification device is used to purify the return gas, remove impurities and moisture, so that the nitrogen can be recycled and the operating cost can be reduced.
