Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of freeze drying devices, in particular to a freeze drying device. Background Art
[0002] Soil is composed of various granular minerals, organic matter, water, air, and microorganisms. The soil has a high internal water content. At present, soil freeze-drying technology requires multiple processing steps such as low-temperature pre-freezing, dehydration and drying, and vacuum sealing to finally obtain soil freeze-dried material. Because soil freeze-dried material has the characteristics of unchanged biological activity, uniform appearance and color, firm structure, and easy storage, it is often used in soil organic matter detection.
[0003] At present, most of the soil freeze dryers on the market are independently set up. The soil treated by the freeze dryer is placed in another instrument for grinding, mixing, standard screening, sampling (optional quartering method), weighing, loading and other operations. On the one hand, this method may cause cross contamination when transferring the dried soil to another instrument, and requires manpower for transfer, and is not fully automated. On the other hand, it requires the configuration of two instruments, which is costly and occupies a large area. Utility Model Content
[0004] In order to solve the above problems, the utility model provides the following technical solutions:
[0005] The utility model provides a freeze drying device, which is arranged in a soil particle size preparation instrument. The freeze drying device includes a freeze drying main unit and a vacuum box, wherein the freeze drying main unit is connected to the vacuum box through a pipeline, and at least one drying placement position is provided in the horizontal direction of the vacuum box, and at least one tray for holding soil samples is placed vertically at each drying placement position. By integrating the freeze drying device into the soil particle size preparation instrument, after drying, the dried soil is directly moved to the next process by a manipulator, and the whole process is completed in the soil particle size preparation instrument, without manual participation and exposure to the external environment, thereby avoiding cross contamination; in addition, at least one drying placement position is provided in the horizontal direction of the vacuum box, and at least one tray is placed vertically at each drying placement position, so that multiple samples can be dried simultaneously, thereby improving the efficiency of sample drying, and at the same time, the overall efficiency of sample preparation is also improved under the action of the manipulator.
[0006] Furthermore, a water catching port is provided on the tray.
[0007] Furthermore, a reverse osmosis membrane is provided in the water collection port, and the reverse osmosis membrane can prevent water or water vapor outside the tray from reverse osmosis into the tray.
[0008] Furthermore, the water collection port is arranged around the opening of the tray.
[0009] Further, at the dry placement position, the trays are stacked.
[0010] Furthermore, a robot is provided on the outside of the vacuum box, and the robot is configured to clamp the tray. When the vacuum cover is raised to the top, the tray with the sample is directly clamped to the next work station by the robot.
[0011] Furthermore, a clamping portion is provided on the tray to facilitate a robot to clamp the tray.
[0012] Furthermore, the vacuum box includes a vacuum cover and a vacuum box bottom, and the vacuum cover is configured to cover the vacuum box bottom so that the vacuum box as a whole forms a closed space.
[0013] Furthermore, the freeze-drying device also includes a box opening device, which is configured to move the vacuum cover away from the bottom of the vacuum box.
[0014] Furthermore, the vacuum box is arranged at the opening of the soil particle size preparation instrument, so that the staff can put the sample to be processed into the vacuum box conveniently.
[0015] The utility model has the following beneficial effects:
[0016] (1) The freeze-drying device of the utility model is directly arranged in the soil particle size preparation instrument. After drying, the dried soil is directly moved to the next process by a manipulator. The whole process is completed in the soil particle size preparation instrument, without manual participation and exposure to the external environment, thus avoiding cross contamination;
[0017] (2) The utility model integrates the freeze drying device into the soil particle size preparation instrument, realizes the fully automatic preparation of soil samples, speeds up the automation process, and greatly reduces the cost compared with the original two devices;
[0018] (3) The vacuum box of the utility model is provided with at least one drying position in the horizontal direction, and each drying position is provided with a plurality of trays for holding soil samples in the vertical direction, so that a large amount of soil can be dried at one time, thereby improving the working material efficiency.
