Description

Technical Field

[0001] This utility model relates to the field of seed sterilization technology, specifically to a plasma sterilization device for sterilizing chili seeds. Background Technology

[0002] Sterilization of chili seeds is a crucial step in agricultural production. Its purpose is to eliminate pathogenic microorganisms (such as fungi, bacteria, and viruses) that may be present on or inside the seeds, ensuring healthy germination, reducing seedling diseases, and improving crop yield and quality. Plasma sterilization devices utilize ionized gas to generate active particles, such as free radicals, ultraviolet light, and charged particles, which can disrupt the structure of microorganisms, achieving highly efficient and broad-spectrum sterilization while avoiding chemical residues.

[0003] Currently, most methods involve spreading the seeds flat on the surface of a conveyor mechanism, allowing them to be sterilized under a sterilization lamp or in a soaking tank. For example, utility model CN221178377U discloses a rice seed sterilization device, including a sterilization box with a partition fixedly connected inside, dividing the box into a sterilization chamber and a cleaning chamber. Sealing devices are installed at both ends of the sterilization box, and sealing plates are connected to the inner surfaces of both sides of the box via hinges. The other end of each sealing plate abuts against the upper end of the partition. A lifting device is also provided inside the sterilization box. This utility model utilizes the rotation of a second coil to control the lifting and lowering of a frame containing rice seeds, allowing it to move within the sterilization and cleaning chambers, reducing intermediate transport paths and improving work efficiency.

[0004] However, existing technology 1 cannot turn the seeds during the sterilization process, which prevents the seeds from fully contacting the sterilization medium and results in incomplete sterilization of the seeds. Utility Model Content

[0005] The purpose of this invention is to provide a plasma sterilization device for sterilizing chili seeds. In practical use, it can solve the problem in the prior art where the sterilization box cannot turn the seeds during the sterilization process, resulting in the seeds not being able to fully contact the sterilization medium and thus the sterilization treatment of the seeds being incomplete.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A plasma sterilization device for sterilizing chili seeds includes a sterilization chamber and a support frame, wherein an elastic element is connected to the support frame, and the sterilization chamber is connected to the support frame through the elastic element.

[0008] The sterilization chamber is tilted downwards, and a plasma disinfection module is installed on the sterilization chamber. The plasma disinfection module is used to input plasma into the sterilization chamber. Several baffle blocks are installed on the sterilization chamber, and the baffle blocks are provided with a guiding arc surface. A vibration motor is installed on the sterilization chamber.

[0009] The sterilization chamber is equipped with an air outlet system, and the air outlet of the air outlet system is tilted upward.

[0010] Preferably, the material stop blocks are arranged alternately from top to bottom.

[0011] Preferably, the feeding end of the sterilization chamber is provided with a baffle plate, and a feeding area is formed between the baffle plate and the sterilization chamber.

[0012] Preferably, filters are installed at the air outlets of the plasma disinfection module and the air outlet system.

[0013] Preferably, the baffle plate is slidably mounted on the sterilization chamber, the baffle plate is provided with fixing holes, and the sterilization chamber is equipped with a fixing mechanism for fixing the baffle plate by cooperating with the fixing holes.

[0014] Preferably, the fixing mechanism includes a connecting block and a fixing bolt threadedly connected to the connecting block, the fixing bolt being used to cooperate with the fixing hole to fix the baffle plate.

[0015] Preferably, the sterilization chamber is provided with a collection box at the discharge end, and the collection box is detachably connected to the sterilization chamber.

[0016] Preferably, a baffle is slidably installed on the collection box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, the movement direction and path of the chili seeds within the sterilization chamber can be altered by the baffles installed inside. When the seeds encounter the baffles, they are forced to change their trajectory, resulting in more complex motion. This helps improve the turning and tossing effect of the seeds, allowing the plasma sprayed by the plasma disinfection module to thoroughly sterilize and disinfect them.

[0019] The guide arc surface set on the baffle block can change the material movement trajectory and extend the path of the material moving in the sterilization chamber, thereby increasing the sterilization time of the plasma disinfection module and achieving a better sterilization effect; the guide arc surface can also guide the material and prevent the material from accumulating in large quantities at the baffle block.

[0020] The air outlet system installed on the sterilization chamber blows air in the opposite direction to the material movement, which generates an upward force on the material. This force can overcome part of the material's weight, making it easier to toss the material up and improving the tossing effect. Attached Figure Description

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] See Figures 1-4 This embodiment discloses a disinfection device for sterilizing seeds, specifically a plasma disinfection device for sterilizing chili seeds, including a sterilization chamber 101 and a support frame 102. An elastic element 103 is connected to the support frame 102, and the sterilization chamber 101 is connected to the support frame 102 through the elastic element 103.

[0036] The sterilization chamber 101 is inclined downwards, and a plasma disinfection module 104 is installed on the sterilization chamber 101. The plasma disinfection module 104 is used to input plasma into the sterilization chamber 101. A plurality of baffle blocks 105 are installed on the sterilization chamber 101, and the baffle blocks 105 are provided with a guide arc surface 106.

[0037] The sterilization chamber 101 is equipped with an air outlet system 108, and the air outlet of the air outlet system 108 is inclined upward.

[0038] In this embodiment, the elastic element 103 is a spring. After the vibration motor 107 is started, the elastic element 103 provides elastic support, allowing the sterilization box 101 to vibrate under the drive of the vibration motor 107. The seeds inside the sterilization box 101 bounce and slide as the sterilization box 101 vibrates. The tilted sterilization box 101 allows the material to be conveyed forward at a suitable speed and trajectory with the help of gravity while vibrating. During the conveying process, the plasma disinfection module 104 installed on the sterilization box 101 can spray plasma onto the material to achieve disinfection. The elastic element 103 also acts as a buffer to prevent collisions between the vibrating sterilization box 101 and the support frame 102. The stop block installed inside the sterilization box 101 can change the movement direction and path of the chili seeds inside the sterilization box 101. When the material encounters the baffle, it is forced to change its trajectory, resulting in more complex motion. This helps improve the tumbling effect, allowing the plasma sprayed by the plasma sterilization module 104 to thoroughly sterilize and disinfect the seeds. The guide arc surface 106 on the baffle block 105 changes the material's trajectory and extends its path within the sterilization chamber 101, thereby increasing the sterilization time of the plasma sterilization module 104 and achieving a better sterilization effect. The guide arc surface also guides the material, allowing it to slide down the arc surface from the top of the baffle block 105, preventing excessive accumulation at the baffle block 105. The air outlet system 108 on the sterilization chamber 101, when blowing air in the opposite direction to the material's movement, generates an upward force on the material. This force overcomes part of the material's gravity, making it easier to toss and improve the tumbling effect. Simultaneously, the horizontal component of the wind can also propel the seeds to move on the sterilization chamber 101. Combined with the vibration of the sterilization chamber 101 itself, this alters the seed trajectory, increasing collisions and friction between seeds and between seeds and the surface of the sterilization chamber 101, thereby improving the turning effect. In this embodiment, the airflow from the air outlet system 108 only slows down the movement speed of the material and increases the sterilization time, without causing the material to move in the opposite direction, thus avoiding affecting the normal feeding of the material. The air outlet system 108 is a conventional air outlet device in the prior art that can adjust the airflow rate. The airflow blown out by the air outlet system 108 is filtered and purified airflow, which will not contaminate the chili seeds. The structure and function of the air outlet device will not be described in detail here.

[0039] In some embodiments, the air outlet of the air outlet system 108 emits air intermittently. In this embodiment, the air outlet system 108 is an existing air outlet device capable of controlling the airflow rate and frequency. The structure and function of the air outlet device will be described in detail here. By making the air outlet of the air outlet system 108 emit air intermittently, the movement speed of the material can be slowed down, the sterilization time of the material can be increased, and the air outlet system 108 can avoid causing excessive obstruction to the movement of the material, thus preventing the material from accumulating in the sterilization chamber 101.

[0040] In some embodiments, the air inlet of the air outlet system 108 is used to connect to a plasma-containing air source device. In this embodiment, the air outlet system 108 can blow a plasma-containing airflow into the sterilization chamber 101, which improves the seed turning effect while disinfecting the seed surface; the cooperation between the plasma disinfection module 104 and the air outlet system 108 can improve the disinfection effect on the seeds; the air source device is a conventional plasma-containing air source device in the prior art, and its structure and function will not be described in detail here.

[0041] In some embodiments, the baffle blocks 105 are staggered from top to bottom. The staggered arrangement of the baffle blocks 105 allows the material to be acted upon at different positions and times, achieving intermittent blocking and pushing, giving the material more opportunities to tumble and scatter under the action of the vibrating motor 107, thus helping to further optimize the tumbling and scattering effect and making the material tumbling more thorough; moreover, the staggered arrangement of the baffle blocks can prevent material from accumulating at the same baffle position. The staggered arrangement of the baffle blocks is relatively dispersed, and the material is guided in a dispersed manner during its forward movement, thereby ensuring the smoothness of material movement and reducing the risk of blockage.

[0042] In some embodiments, a baffle plate 109 is provided at the feed end of the sterilization chamber 101, forming a feed area between the baffle plate 109 and the sterilization chamber 101. By setting the baffle plate 109, the amount of material entering the sterilization chamber 101 is controlled, avoiding a large amount of material from rushing into the sterilization chamber 101 at once and causing material accumulation, which would affect the sterilization effect of the plasma disinfection module 104 on the material.

[0043] In some embodiments, filters are installed at the air outlets of the plasma sterilization module 104 and the air outlet system 108. By setting the filters, it is possible to prevent seeds from entering the air outlets of the plasma sterilization module 104 and the air outlet system 108 when they are turned and thrown up in the sterilization chamber 101, thus preventing them from affecting the use of the plasma sterilization module 104 and the air outlet system 108.

[0044] In some embodiments, the baffle plate 109 is slidably mounted on the sterilization chamber 101. The baffle plate 109 is provided with fixing holes 110, and the sterilization chamber 101 is equipped with a fixing mechanism 111 for fixing the baffle plate 109 by cooperating with the fixing holes 110. By allowing the baffle plate 109 to slide on the sterilization chamber 101, the size of the feeding area formed between the baffle plate 109 and the sterilization chamber 101 can be adjusted to meet the needs of different production processes according to actual conditions. The baffle plate 109, adjusted to a predetermined position, can be fixed by the cooperation of the fixing holes 110 and the fixing mechanism 111. In this embodiment, there are two fixing mechanisms 111, which are arranged on the front and rear sides of the baffle plate 109.

[0045] In some embodiments, the fixing mechanism 111 includes a connecting block 112 and a fixing bolt 113 threadedly connected to the connecting block 112. The fixing bolt 113 is used to cooperate with the fixing hole 110 to fix the baffle plate 109. When it is necessary to move the baffle plate 109, rotating the fixing bolt 113 so that the fixing bolt 113 moves outside the fixing hole 110 can pull the baffle plate 109 to adjust the size of the feeding area formed between the baffle plate 109 and the sterilization chamber 101. After the baffle plate 109 is adjusted to a predetermined position, rotating the fixing bolt 113 in the opposite direction can move the fixing bolt 113 into the fixing hole 110 to fix the baffle plate 109.

[0046] In some embodiments, a collection box 114 is provided at the discharge end of the sterilization chamber 101, and the collection box 114 is detachably connected to the sterilization chamber 101. The collection box 114 is used to collect the sterilized seed material. The discharge end of the sterilization chamber 101 is provided with a chute, and a slide rail for cooperating with the chute is connected to the collection box 114. The collection box 114 is slidably installed in the chute via the slide rail, which facilitates the operator to remove the collection box 114 and transfer the sterilized material.

[0047] In some embodiments, a baffle 115 is slidably mounted on the collection box 114. The collection box 114 is provided with a clearance groove, and the baffle 115 is slidably mounted in the clearance groove. Before transferring the collection box 114, the baffle 115 is pushed to block the opening of the collection box 114, preventing external impurities and bacteria from contaminating the sterilized seeds inside the collection box 114 during the transfer process. In this embodiment, a sealing strip is installed on the baffle 115 to seal the gap between the baffle 115 and the collection box 114, preventing external impurities and bacteria from entering the collection box 114 through the gap between the baffle 115 and the collection box 114.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
