Description

Technical Field

[0001] This utility model relates to the field of specimen drying technology, and in particular to a specimen drying device. Background Technology

[0002] Specimens are physical objects used for learning, research, or reference. After processing, they can be preserved for a long time while maintaining their original appearance as much as possible for exhibitions, education, identification, verification, and various research purposes. After collecting plant, fungal, and algal specimens outdoors, they need to be dried promptly. Timely drying reduces the risk of damage caused by moisture during storage and helps prevent moisture regain. However, existing specimen drying equipment, when drying plant, fungal, and algal specimens, results in uneven drying due to the upward flow of hot air, leading to unsatisfactory drying results. Utility Model Content

[0003] The technical problem to be solved by this invention is to provide a specimen drying device that can achieve uniform drying.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A specimen drying device includes a drying body, a hot air pipe connected to the hot air outlet of the drying body, a frame fixed to the drying body, several grids fixed in the frame, and several hot air branch pipes connected to the hot air pipes and located below the grids; several drying boxes are evenly placed on each layer of the grids; several air holes are opened on the hot air branch pipes.

[0006] Furthermore, several hot air pipes located below each layer of the grid are arranged in a divergent pattern, and the diameter of the air vents decreases sequentially from bottom to top according to the grid arrangement direction.

[0007] Furthermore, the hot air duct is arranged vertically and coaxially with the frame.

[0008] Furthermore, several dividing strips are evenly fixed on the grid; the drying box is placed between the spaces separated by the dividing strips and can be pulled out of the space composed of the grid and the frame.

[0009] Furthermore, the drying box includes a frame and a breathable mesh located at the bottom of the frame.

[0010] Furthermore, a handle is fixed to the frame of the drying box on the side away from the hot air pipe.

[0011] Furthermore, a sterilization cover is detachably connected to the drying body; the sterilization cover is electrically connected to a controller located inside the drying body.

[0012] Furthermore, the disinfection and sterilization cover includes a cover body with a hot air passage at the upper end and several ultraviolet lamps fixed inside the cover body and arranged vertically in an axial direction, and two clips symmetrically arranged at the lower end of the ultraviolet lamps; the drying body is provided with a clip sleeve that matches the clips.

[0013] Furthermore, one of the card blocks is provided with a first contact point; the drying body below one of the card sleeves is provided with a second contact point; the ultraviolet lamp is electrically connected to the controller after contacting the first contact point and the second contact point.

[0014] The beneficial effects of this utility model are:

[0015] (1) The hot air is generated by the hot air blower on the drying body controlled by the controller. The hot air flows through the hot air pipe to the hot air branch pipe and flows out from the air hole to dry the specimen placed in the drying box. By setting the air hole diameter to gradually decrease from bottom to top, energy can be effectively saved. Since the hot air will flow upward, the specimen located at the bottom can be dried by the hot air flowing out through the large hole diameter. The hole diameter decreases from top to bottom, but the hot air at the bottom can also dry the specimen at the top, ensuring the uniformity of drying. Compared with the same hole diameter, the hot air at the top will over-dry the specimen or the bottom will not dry enough. This has a better drying effect.

[0016] (2) By setting up a frame and grid, the drying box can be pulled out and arranged in a ring around the hot air pipe on the grid, making it more convenient to take out the drying box. Attached Figure Description

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] A specimen drying apparatus, as described above Figure 1-9 As shown, it includes a drying body 1, a hot air pipe 3 connected to the hot air outlet of the drying body 1, a frame 4 fixed to the drying body 1, several grids 5 fixed inside the frame 4, and several hot air branch pipes 6 connected to the hot air pipe 3 and located below the grids 5; several drying boxes 7 are evenly placed on each grid 5; several air holes 8 are opened on the hot air branch pipes 6.

[0031] It should be noted that the drying body 1 is the control device and the main body for generating hot air in the existing specimen drying device. The hot air pipe 3 can be connected to the hot air outlet of the hot air blower inside the drying body 1 to facilitate the outflow of hot air. The frame 4 is used to support the drying box 7 and the specimen in the drying box 7 and is transparent, so that the drying process can be easily observed. The materials of the frame 4, the drying box 7 and other parts that come into contact with high temperature are all made of materials that can withstand a certain temperature. The upper part of the frame 4 is open, and a screen can also be set to ensure that the specimen on the upper part is not damaged. The frame 4 and the drying box 7 in this application are made of medium heat-resistant PC plastic. The grid 5 can facilitate the passage of hot air from the air holes 8 opened on the hot air branch pipe 6. The hot air branch pipe 6 and the air holes 8 can facilitate the outflow of hot air. The hot air branch pipe 6 is fixed to the grid by a fastener to ensure stability. The fastener can be made of materials such as iron wire. And the air hole 8 is opened vertically upward. The drying box 7 is a box with a breathable bottom, which can accommodate the specimen.

[0032] To facilitate uniform hot air distribution, several hot air pipes 6 located below each layer of the grid 5 are arranged in a divergent pattern, and the apertures of the air holes 8 decrease in size from bottom to top along the grid 5 arrangement. Since hot air flows upwards, the specimens on the lower grid 5 are dried by the hot air flowing out through the larger apertures. As the apertures decrease upwards, the hot air from below can still dry the specimens above, ensuring uniform drying. This method achieves better drying results compared to using the same aperture, which can lead to over-drying of the specimens above or under-drying below. In this application, the hot air pipes 3 are vertically aligned coaxially with the frame 4 to ensure smooth airflow.

[0033] In this application, there are 5 grids 5, with a spacing of 15-18cm between the two layers of grids 5. In this application, the spacing is 16cm. Each layer of grids 5 has 6 equally distributed drying boxes 7 that are easy to remove. To ensure the drying of the specimens in the drying boxes 7, at least 6 hot air pipes 6 are set under each layer of grids 5. In this application, the number is 12. Several dividing strips 51 are evenly fixed on the grids 5, and the number of dividing strips 51 matches the number of drying boxes 7. The drying boxes 7 are placed between the spaces separated by the dividing strips 51 and can be removed from the space consisting of the grids 5 and the frame 4.

[0034] To facilitate the entry of hot air into the drying box 7 from below, the drying box 7 includes a frame 71 and a breathable mesh 72 located at the bottom of the frame 71. A handle 73 is fixedly connected to the frame 71 on the side of the drying box 7 away from the hot air pipe 3, and the handle 73 can be used to easily remove the drying box 7.

[0035] After the specimens are dried, they need to be disinfected with ultraviolet light to ensure long-term preservation. Therefore, a disinfection and sterilization cover 10 is detachably connected to the drying body 1. The disinfection and sterilization cover 10 is electrically connected to the controller 2 located inside the drying body 1. The controller 2 can control the opening and closing of the disinfection and sterilization cover 10 and the duration of the disinfection and sterilization. The controller 2 is a controller in the prior art. The principle of the controller 2 is easy to understand for those who frequently use it in the field. Those skilled in the art can also choose according to their own needs.

[0036] After drying, the specimens need to be disinfected. The disinfection and sterilization hood 10 includes a hood body 101 with a hot air vent at the top, several ultraviolet lamps 102 fixed inside the hood body 101 and arranged vertically along the axis, and two locking blocks 103 symmetrically arranged at the lower ends of the ultraviolet lamps 102; the drying body 1 is provided with a locking sleeve 11 that fits the locking blocks 103. When the disinfection and sterilization hood 10 is connected to the drying body 1, the locking blocks 103 and the locking sleeve 11 are first misaligned and released so that the lower end of the disinfection and sterilization hood 10 contacts the drying body 1, and then... Figure 1The disinfection and sterilization cover 10 is rotated counterclockwise in the direction of the middle, so that the locking block 103 is locked into the locking sleeve 11. At this time, the first contact point 104 and the second contact point 12 make the disinfection and sterilization cover 10 electrically connected to the controller 2. The cover body 101 is made of an opaque material, such as opaque plastic. The ultraviolet lamp tube 102 is a product in the prior art. This application uses a commercially available product with the model number ZW10S15W.

[0037] To facilitate the removal and attachment of the sterilization cover 10 to the drying body 1, one of the clips 103 has a first contact point 104; the drying body 1 below one of the clips 11 has a second contact point 12; the ultraviolet lamp 102 is electrically connected to the controller 2 after contacting the first contact point 104 and the second contact point 12. This method allows the sterilization cover 10 to be attached to the drying body 1 when specimen sterilization is required.

[0038] The working principle of this utility model:

[0039] During specimen drying, the hot air is generated by the hot air blower on the drying body 1 controlled by the controller 2. The hot air flows through the hot air pipe 3 to the hot air branch pipe 6 and flows out from the air hole 8 to dry the specimen placed in the drying box 7. By setting the diameter of the air hole 8 to gradually decrease from bottom to top, energy can be effectively saved. Since the hot air will flow upward, the specimen located at the bottom can be dried by the hot air flowing out through the large diameter hole. As the diameter decreases upward, the hot air at the bottom can also dry the specimen at the top, ensuring the uniformity of drying. Compared with the same hole diameter, which leads to the hot air at the top over-drying the specimen or the bottom under-drying, this method has a better drying effect.

[0040] By setting the frame 4 and the grid 5, the drying box 7 can be pulled out and arranged in a ring around the hot air pipe 3 on the grid 5, which makes it more convenient to take out the drying box 7 compared to the stacked arrangement.

[0041] The drying device of this application is suitable for biological specimens such as plant specimens, fungal specimens and algal specimens, enabling them to remove moisture and facilitate preservation.

[0042] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
