Description

Technical Field

[0001] This utility model relates to the field of seedling substrate production technology, specifically a high-temperature drying and sterilization device for seedling substrate production. Background Technology

[0002] Seedling substrate is a synthetic or natural material used to cultivate seedlings. It provides a good environment and necessary nutrients for seed germination and seedling growth. High-temperature drying and sterilization equipment is required when producing seedling substrate.

[0003] A search revealed that the patent, CN222723364U, entitled "Utility Model of a Seedling Substrate Sterilization Device," includes a box. Research and analysis revealed that although it can ensure the temperature uniformity of various parts within the box during use, thus guaranteeing the sterilization effect, it also has the following disadvantages to a certain extent.

[0004] For example, if the equipment lacks a tapping function, during the feeding stage, the mixing tank cannot be tapped, causing a large amount of seedling substrate to adhere to the surface of the mixing rod, which is difficult to remove. This not only affects the normal mixing effect of the mixing rod but also increases the difficulty of cleaning and reduces the working efficiency of the equipment. At the same time, it lacks a waste heat utilization function. After the equipment generates steam during operation, the waste heat carried by the steam cannot be recovered and utilized, resulting in energy waste. In order to solve the above technical problems, we have designed a high-temperature drying and sterilization equipment for seedling substrate production. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature drying and sterilization device for seedling substrate production, which has the advantages of a tapping function and waste heat recovery and utilization function. It solves the problem that existing high-temperature drying and sterilization devices cannot tap the mixing box during use, resulting in a large amount of seedling substrate that is difficult to fall off easily adhering to the surface of the mixing rod, and cannot recover and utilize the waste heat carried by the steam.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature drying and sterilization device for seedling substrate production, comprising a box body, a partition fixedly connected to the inner cavity of the box body, a heat-conducting cylinder fixedly connected through the top of the inner cavity of the box body, heat-conducting plates fixedly connected to the surface of the heat-conducting cylinder, fans fixedly connected through the top of both sides of the box body, ventilation holes provided at the top of the partition plate, and electric push rods bolted to both sides of the box body. The output end of the electric push rod extends through the inner cavity of the box body and is bolted to an infrared microwave heating component. The front and rear sides of both sides of the internal cavity are riveted with first support plates. The top of the first support plate is bolted to a spring. The top of the spring is bolted to a second support plate. A stirring hopper is riveted to the opposite side of the second support plate. A drive motor is bolted to the right side of the stirring hopper. The output end of the drive motor passes through the internal cavity of the stirring hopper and is bolted to a rotating rod. A stirring rod is fixedly installed on the surface of the rotating rod. A cylinder is bolted to the right side of the box. The output end of the cylinder passes through the internal cavity of the box and is bolted to a striking block.

[0007] Preferably, air inlets are provided on the top of both sides of the box, and an observation window is installed on the top of the front side of the box.

[0008] Preferably, the bottom of the heat-conducting cylinder is connected to a discharge valve, and the bottom end of the discharge valve is connected to a partition.

[0009] Preferably, an iron block is riveted to the top right side of the mixing hopper, and the striking block is located to the right of the iron block.

[0010] Preferably, the front side of the box is movably connected to a box door via a hinge, and the four corners of the bottom of the box are riveted with support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has the advantage of a striking function through the cooperation of a first support plate, a spring, a second support plate, a mixing hopper, a cylinder, and a striking block. When feeding, the external controller controls the cylinder to work, and the output end of the cylinder drives the striking block to move quickly. The striking block hits the surface of the iron block, at which time the mixing hopper and the mixing rod begin to vibrate, thereby shaking off the attached seedling substrate and preventing it from adhering to the surface of the mixing hopper and the mixing rod.

[0015] 2. This utility model has the advantage of waste heat reuse function through the combination of partition, heat conduction cylinder, heat conduction plate, fan and ventilation hole. The external controller controls the operation of the fan. The water vapor generated during heating and drying is transported to the top of the partition through the ventilation hole. The heat of the steam is transferred to the heat conduction cylinder through the heat conduction plate. The heat conduction cylinder transfers the heat to the seedling substrate inside, thereby preheating the seedling substrate. Attached Figure Description

[0022] Please see Figures 1-5A high-temperature drying and sterilization device for seedling substrate production includes a box body 1. A partition 2 is fixedly connected to the inner cavity of the box body 1, dividing the inner cavity into different areas. Combined with ventilation holes 6, the steam generated during heating and drying can be transported to specific areas, facilitating the reuse of waste heat. A heat-conducting cylinder 3 is fixedly connected through the top of the inner cavity of the box body 1. The heat-conducting cylinder 3 serves two purposes: storing the seedling substrate and absorbing heat from the steam through heat-conducting plates 4, transferring the heat to the seedling substrate inside for preheating and improving energy efficiency. Heat-conducting plates 4 are fixedly connected to the surface of the heat-conducting cylinder 3. Fans 5 are fixedly connected through the top of the box body 1 on both sides. Ventilation holes 6 are provided at the top of the partition 2. Electric push rods 7 are bolted to both sides of the box body 1, with the output end of the electric push rod 7 extending through to... The inner cavity of the box 1 is connected to an infrared microwave heating component 8 by bolts. By setting the infrared microwave heating component 8, the seedling substrate inside the mixing hopper 12 can be heated, dried and sterilized. The front and rear sides of both sides of the inner cavity of the box 1 are riveted with first support plates 9. The top of the first support plate 9 is connected to a spring 10 by bolts. The top of the spring 10 is connected to a second support plate 11 by bolts. The mixing hopper 12 is riveted to the opposite side of the second support plate 11. The right side of the mixing hopper 12 is connected to a drive motor 13 by bolts. The output end of the drive motor 13 passes through the inner cavity of the mixing hopper 12 and is connected to a rotating rod 14 by bolts. A stirring rod 15 is fixedly installed on the surface of the rotating rod 14. The right side of the box 1 is connected to a cylinder 16 by bolts. The output end of the cylinder 16 passes through the inner cavity of the box 1 and is connected to a striking block 17 by bolts.

[0023] Please see Figure 1 and Figure 2 Air inlets 18 are provided on the top of both sides of the box 1, and observation windows 19 are installed on the top of the front side of the box 1.

[0024] Please see Figure 1 The bottom of the heat-conducting cylinder 3 is connected to a discharge valve 20. By setting the discharge valve 20, the flow rate and time of the seedling substrate entering the mixing hopper 12 from the heat-conducting cylinder 3 can be controlled. At the same time, after the preheating is completed, the discharge valve 20 is closed, and new seedling substrate can be added into the heat-conducting cylinder 3. The bottom end of the discharge valve 20 is connected to the partition plate 2.

[0025] Please see Figure 3 An iron block 21 is riveted to the top right side of the mixing hopper 12. By setting the iron block 21, it can cooperate with the striking block 17. When the striking block 17 strikes, it transmits the vibration to the mixing hopper 12 and the mixing rod 15. The striking block 17 is located to the right of the iron block 21.

[0026] Please see Figure 2 The front of the box 1 is connected to the door 22 by a hinge, and the four corners of the bottom of the box 1 are riveted with support legs.

[0027] Please see Figure 3 The front and rear sides of the bottom of the mixing hopper 12 are riveted with guide plates 23. By setting the guide plates 23, it is helpful for the seedling substrate to be discharged smoothly through the electric valve 24 after mixing. The left end of the rotating rod 14 is movably connected to the mixing hopper 12 through a bearing.

[0028] Please see Figure 5 The bottom of the mixing hopper 12 is connected to an electric valve 24. By setting the electric valve 24, the sterilized and dried seedling substrate can be discharged. The bottom of the electric valve 24 is connected to a telescopic pipe 25, and the bottom end of the telescopic pipe 25 penetrates the box body 1.

[0029] In use, connect an external power supply and controller to the device. The external controller opens the discharge valve 20, allowing the seedling substrate to be transported into the mixing hopper 12 via the heat-conducting cylinder 3 and discharge valve 20. The external controller then closes the discharge valve 20 and adds new seedling substrate into the heat-conducting cylinder 3. The external controller then controls the drive motor 13 to operate, and the output of the drive motor 13 drives the rotating rod 14 and the stirring rod 15 to rotate. Subsequently, the external controller controls the electric push rod 7 and the infrared microwave heating component 8 to operate. The infrared microwave heating component 8 heats, dries, and sterilizes the seedling substrate inside the mixing hopper 12. The output of the electric push rod 7 drives the infrared microwave heating component 8 to move back and forth, generating a large amount of water vapor during the heating process. The external controller controls the operation of the fan 5. The water vapor generated during heating and drying is transported to the top of the partition 2 through the ventilation hole 6. The heat of the steam is transferred to the heat-conducting cylinder 3 through the heat-conducting plate 4. The heat-conducting cylinder 3 transfers the heat to the seedling substrate inside, thereby preheating the seedling substrate. When feeding, the external controller controls the cylinder 16 to work. The output end of the cylinder 16 drives the striking block 17 to move quickly. The striking block 17 hits the surface of the iron block 21. At this time, the mixing hopper 12 and the mixing rod 15 begin to vibrate, thereby shaking off the attached seedling substrate and preventing it from adhering to the surface of the mixing hopper 12 and the mixing rod 15. The dried and sterilized seedling substrate is discharged to the bottom of the box 1 through the electric valve 24 and the telescopic pipe 25.

[0030] In summary, this high-temperature drying and sterilization equipment for seedling substrate production, through the coordination of the first support plate 9, spring 10, second support plate 11, mixing hopper 12, cylinder 16, striking block 17, partition plate 2, heat-conducting cylinder 3, heat-conducting plate 4, fan 5, and ventilation hole 6, solves the problems of existing high-temperature drying and sterilization equipment that cannot be used to strike the mixing box during operation, resulting in a large amount of seedling substrate that is difficult to fall off easily adhering to the surface of the mixing rod, and the inability to recover and utilize the residual heat carried by the steam.
