Description

Technical Field

[0001] This utility model belongs to the field of salt-alkali tolerant seedling detoxification technology, specifically relating to a hot air circulation type salt-alkali tolerant seedling detoxification device. Background Technology

[0002] Virus removal from salt-tolerant seedlings aims to eliminate pathogens such as viruses, viroids, and bacteria that may be present in the seedlings. These pathogens can weaken seedling growth, causing problems such as yellowing, stunting, and reduced yield and quality. After virus removal, seedlings grow more robustly, with enhanced salt and alkali tolerance and stress resistance, resulting in significantly improved yield and quality. This is of great significance for greening saline-alkali land, ecological restoration, and agricultural production. A hot air circulation device ensures uniform heating of all parts of the seedlings by circulating hot air. It utilizes hot air to inactivate viruses, which are then eliminated by the plant itself, resulting in excellent virus removal effects. The device is simple to operate, requiring only the placement of seedlings and setting the temperature and time. It is safe, pollution-free, and harmless to the seedlings, making it suitable for virus removal in salt-tolerant seedlings.

[0003] Chinese utility model patent CN216853166U discloses a hot air circulation type grape seedling detoxification device, including a detoxification chamber, a holding rack, and a hot air circulation device. The bottom of the detoxification chamber is equipped with a guide positioning device, which includes a guide rail and a positioning component. The hot air circulation device includes a hot air conveying component, an air heating device, and a hot air return component. The hot air conveying component is connected to the air heating device, and its outlet extends from the top of the detoxification chamber into the interior. The inlet of the hot air return component extends from the bottom of the detoxification chamber into the interior, and is connected to the air heating device. In use, workers push the holding rack into the detoxification chamber and fix it using the guide rail and positioning component, placing the rack sequentially along the guide rail. Hot air is input from the top of the detoxification chamber using the hot air conveying component, while the hot air return component draws back air to ensure the hot air inside the detoxification chamber is in a flowing state, thus maintaining uniformity.

[0004] However, in the process of using the above-mentioned patent, since the outlet end of the hot air conveying component extends from the top of the detoxification chamber to the inside of the detoxification chamber, and the inlet end of the return component extends from the bottom of the detoxification chamber to the inside of the detoxification chamber, due to the principle that hot air rises when heated, this setting method cannot make the hot air in the detoxification chamber flow better. Moreover, the hot air enters the detoxification chamber from the top, which inevitably blows directly onto the seedlings and affects them. Secondly, it cannot monitor the situation inside the detoxification chamber in real time, and the design of the guide rail is too complicated. It can be simplified. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, this utility model provides a hot air circulation type detoxification device for salt-alkali tolerant seedlings to solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A hot air circulation type detoxification device for salt-alkali tolerant seedlings includes a base and a main body shell installed on the base. A PLC controller is installed on the main body shell. A chamber door is provided on the front side. The inside is a detoxification chamber and an air circulation device. The top of the detoxification chamber is provided with a return hole, the bottom is equipped with guide rails, and air inlets are provided between the guide rails.

[0008] Furthermore, the door is connected to the detoxification chamber, and the door is equipped with a handle.

[0009] The above structural design facilitates the opening of the storage door, allowing for the placement and retrieval of seedlings.

[0010] Furthermore, a humidifier is installed on the top of the detoxification chamber, and a temperature and humidity sensor is installed on the side wall. The output of the temperature and humidity sensor is connected to a PLC controller, and the output of the PLC controller is connected to the humidifier.

[0011] By adopting the above structural design, the temperature and humidity sensor monitors the temperature and humidity inside the detoxification chamber and transmits the data to the PLC controller in a timely manner for easy monitoring and adjustment of the air heater and humidifier settings according to the temperature and humidity.

[0012] Furthermore, the detoxification chamber is equipped with a shelf, and a daylight lamp is installed on the side wall according to the shelf. A tray is placed on the shelf, and casters are installed at the bottom. The casters can move along the guide rail, and brake pads are installed on the casters.

[0013] By adopting the above structural design, when placing or taking seedlings, only the shelf needs to be moved. The design of casters and guide rails facilitates the movement of the shelf and prevents it from shifting. Brake pads fix the shelf in place, and the installation of daylight lamps is beneficial to the growth of seedlings.

[0014] Furthermore, the air circulation device includes an air heater, an air pump, and an air storage chamber. One end of the air pump is connected to the return hole at the top of the detoxification chamber through a return pipe, and the other end is connected to the bottom of the air heater through a first conduit. The top of the air heater at the end away from the first conduit is connected to the air storage chamber through a second conduit.

[0015] Furthermore, the gas storage chamber is installed below the detoxification chamber, is hollow inside, and has its top sides connected to the second conduit, with an air inlet at the top.

[0016] By adopting the above structural design, hot air enters the detoxification chamber from the bottom and moves upward. Through the pumping of the air pump, the gas in the detoxification chamber enters the bottom of the air heater through the return hole, return pipe, air pump, and first conduit. After being heated by the air heater, the hot air rises and enters the gas storage chamber through the second conduit at the top. The hot air accumulates in the gas storage chamber and enters the detoxification chamber through the air inlet at the top to complete the circulation.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. By setting up an air storage chamber, hot air is accumulated and then enters the detoxification chamber through the air inlet, avoiding direct hot air blowing on the seedlings on the shelf. The air inlet is installed at the bottom of the detoxification chamber, and the principle of air rising when heated is used to make the detoxification chamber evenly heated.

[0019] 2. Install temperature and humidity detectors in the detoxification chamber and transmit the data to the PLC controller in a timely manner for easy monitoring. Adjust the settings of the air heater and humidifier according to the temperature and humidity. In addition, the use of a daylight lamp can help the seedlings grow better in the detoxification chamber.

[0020] 3. By installing swivel casters with brake pads at the bottom of the shelf, the design of the guide rail and shelf is simplified, preventing the shelf from shifting while facilitating the pushing and placing of the shelf. Attached Figure Description

[0032] Example 1:

[0033] like Figure 1-5As shown, this utility model specifically includes a hot air circulation type detoxification device for salt-tolerant seedlings, comprising a base 1, a main body shell 2 mounted on the base 1, a PLC controller 3 mounted on the main body shell 2, a door 4 on the front, a detoxification chamber 5 inside, and an air circulation device 6. The detoxification chamber 5 has a return hole 63 at the top and guide rails 54 at the bottom, with air inlets 641 between the guide rails 54. The door 4 is connected to the detoxification chamber 5 and has a handle 41.

[0034] The handle 41 makes it easy to open the door 4, allowing for the placement and removal of seedlings. The bottom of the virus-free chamber 5 has multiple sets of guide rails 54, each set of guide rails 54 is arranged in parallel opposite directions, and air inlets 641 are evenly distributed between the guide rails to facilitate the entry of hot air and prevent hot air from blowing directly on the seedlings, which would affect their growth.

[0035] In this example, a humidifier 51 is installed on the top of the detoxification chamber 5, and a temperature and humidity sensor 53 is installed on the side wall. The output of the temperature and humidity sensor 53 is connected to the PLC controller 3, and the output of the PLC controller 3 is connected to the humidifier 51. The temperature and humidity sensor 53 monitors the temperature and humidity inside the detoxification chamber 5 and transmits the data to the PLC controller 3 in a timely manner for easy monitoring and adjustment of the settings of the air heater 61 and the humidifier 51 according to the temperature and humidity.

[0036] In this example, a shelf 7 is installed inside the detoxification chamber 5, and a daylight lamp 52 is installed on the side wall of the shelf 7. A tray 71 is placed on the shelf 7, and casters 72 are installed at the bottom. The casters 72 can move along the guide rail 54, and brake pads 721 are installed on the casters 72. When placing or taking seedlings, only the shelf 7 needs to be moved. The design of the casters 72 and the guide rail 54 facilitates the movement of the shelf 7 and prevents it from shifting. The brake pads 721 fix the shelf 7 in place, and the daylight lamp 52 is beneficial to the growth of the seedlings.

[0037] In this example, the air circulation device 6 includes an air heater 61, an air pump 62, and an air storage chamber 64. One end of the air pump 62 is connected to the return hole 63 at the top of the detoxification chamber 5 via a return pipe 631, and the other end is connected to the bottom of the air heater 61 via a first conduit 611. The top of the end of the air heater 61 away from the first conduit 611 is connected to the air storage chamber 64 via a second conduit 612. The air storage chamber 64 is installed below the detoxification chamber 5, is hollow inside, and its tops on both sides are connected to the second conduit 612. An air inlet 641 is provided at the top. Hot air enters the detoxification chamber 5 from the bottom and moves upward. Through the pump 62, the gas in the detoxification chamber 5 enters the bottom of the air heater 61 through the return hole 63, return pipe 631, air pump 62, and first conduit 611. After being heated by the air heater 61, the hot air rises and enters the gas storage chamber 64 through the second conduit 612 at the top. The hot air accumulates in the gas storage chamber 64 and enters the detoxification chamber 5 through the air inlet 641 at the top to complete the circulation.

[0038] When using this invention, operators need to set the temperature and humidity ranges according to the actual situation, and set the corresponding settings for the air heater 61 and humidifier 51 based on these ranges. Furthermore, the main body shell 2, the door 4, and the detoxification chamber 5 of this invention can be made of insulating materials.

[0039] Working principle: When the seedlings need to be detoxified, the staff needs to pull handle 41 to open the door 4, pull out the required shelf 7, put in the seedlings, push the shelf 7 along the guide rail 54 to the appropriate position, fix the shelf 7 with brake pad 721, close the door 4, turn on the air circulation device 6, and turn on the daylight lamp 52 as needed. According to the data sensed by the temperature and humidity sensor 53, the PLC controller 3 adjusts the speed of the air heater 61 and humidifier 51 according to the preset speed. When the seedlings need to be taken out, turn off the power, pull handle 41 to open the door 4, pull out the shelf 7, and take out the seedlings.
