Description

Technical Field

[0001] The present application relates to the technical field of soil detection, and in particular to a sample pretreatment device for soil detection and analysis. Background Art

[0002] In soil science research and environmental testing, soil sample pretreatment is a key step in obtaining accurate analytical data. Drying, as an important method for removing excess water from soil samples, has a direct impact on subsequent chemical analysis and physical property determination.

[0003] Specifically, most soil drying equipment uses fixed drying containers, requiring manual loading and unloading of soil samples before and after drying. This process is particularly time-consuming and laborious due to the elevated temperature of the dried samples, which can form lumps and soil particles. This undoubtedly increases workload and reduces efficiency, particularly for laboratories that frequently process samples.

[0004] More importantly, static heating of the sample after placement in the drying container often results in uneven heat distribution between the inner and outer layers of the sample. This uneven heat distribution directly affects the evaporation rate of the sample's internal moisture, resulting in inconsistent drying results. This can, to a certain extent, reduce the accuracy of subsequent analytical results.

[0005] In addition, the static heating method also means that the drying process takes a long time to complete, which further extends the sample processing cycle.

[0006] In view of the above problems, a sample pretreatment device for soil detection and analysis is now designed. Utility Model Content

[0007] The embodiment of the present application provides a sample pretreatment device for soil detection and analysis to solve the problems in the related art of inconvenient material removal from soil drying containers and uneven drying.

[0014] In some embodiments, the support seat includes mounting plates relatively arranged inside the chamber, a support block is arranged between the two mounting plates, the support block is U-shaped, and the rotating shaft is rotatably arranged inside the support block.

[0015] In some embodiments, the driving member includes a reducer provided on the processing box, and a driving motor provided on the reducer, wherein an output shaft of the driving motor is connected to an input shaft of the reducer;

[0016] The output shaft of the reducer extends to the inside of the chamber, and one end of the rotating shaft on one side passes through the mounting plate and extends outward. The output shaft of the reducer and the end of the rotating shaft on one side extending outward are both provided with transmission wheels, and the two transmission wheels fit together.

[0017] In some embodiments, two supporting plates are disposed opposite to each other inside the chamber, and the supporting plates are L-shaped, and the tray is arranged above the two supporting plates.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] The embodiment of the present application provides a sample pretreatment device for soil detection and analysis, which can solve the problems in the related art of inconvenient material removal from soil drying containers and uneven drying.

[0031] See also Figure 1-Figure 3 A sample pretreatment device for soil detection and analysis includes: a processing box 1, a drying cage 2 and a flip cover 3 hinged on the processing box 1; the processing box 1 is provided with a chamber 4 for soil drying, the upper part of the chamber 4 is open, and support seats 5 are relatively arranged inside the chamber 4; the drying cage 2 is rotatably arranged between the two support seats 5, and a mesh cover 21 is hinged on the drying cage 2; the processing box 1 is also provided with a driving member 6, and the driving member 6 is used to drive the drying cage 2 to rotate; a plurality of fans 7 and a plurality of groups of electric heating rods 8 are arranged from bottom to top inside the chamber 4; a tray 11 is also provided inside the chamber 4, and the tray 11 is located between the electric heating rod 8 and the drying cage 2 and is used to receive the liquid dripping from the drying cage 2; a stirring rod 12 is provided inside the drying cage 2.

[0032] In view of the above-cited background technology, the following is a detailed description of the working principle and beneficial effects of the sample pretreatment device for soil detection and analysis, wherein the beneficial effects closely correspond to the technical problems raised in the background technology.

[0033] First, open the hinged cover 3 on the processing box 1, put the soil sample to be dried into the drying cage 2, and cover the drying cage with the mesh cover 21 to prevent the sample from scattering during the rotation process. Then close the hinged cover 3 to ensure that the interior of the processing box 1 is sealed.

[0034] The driver 6 built into the processing box 1 is activated, causing the drying cage 2 to rotate between the two support bases 5. The rotating drying cage 2 helps break down the thermal barrier within the sample, promoting the even distribution of heat and air within the sample. Simultaneously, multiple sets of electric heating rods 8 within the chamber 4 begin operating, releasing heat to heat the sample. To accelerate the evaporation and discharge of moisture, multiple fans 7 are arranged from bottom to top within the chamber 4. These fans form a bottom-up hot air flow, further enhancing the drying effect.

[0035] During the drying process, the moisture in the soil sample gradually evaporates, and some liquid may drip to the bottom of the drying cage 2 or through the pores in the mesh cover 21. At this point, the tray 11 located between the electric heating rod 8 and the drying cage 2 acts as a catch, preventing the liquid from dripping downward and effectively collecting any liquid that does drip from the bottom of the drying cage 2 or through the pores in the mesh cover 21. As the drying cage 2 turns, the stirring rod 12 inside it gently stirs the sample, further improving drying uniformity.

[0036] By combining the rotating drying cage 2 with a multi-dimensional heating and ventilation system, the device can significantly shorten the drying time of soil samples and improve drying efficiency. The rotational motion promotes even distribution of heat and air, accelerating water evaporation.

[0037] The rotating drying cage 2 and stirring rod 12 help to break the heat barrier inside the sample and achieve uniform distribution of heat and air in the sample, thereby ensuring drying uniformity and avoiding the uneven drying problem caused by traditional static heating methods.

[0038] The drying cage 2 adopts an integrated design and can be taken out separately. The staff only needs to put the sample into the drying cage 2, close the flip cover 3 and start the device, which is convenient for the staff to load and unload materials, and at the same time, it is easy for the staff to clean and replace it.

[0039] Specifically, in this embodiment, the drying cage 2 is a prismatic mesh cage or a cylindrical mesh, an opening is provided on one side of the drying cage 2, the mesh cover 21 is hinged at the opening of the drying cage 2, and the other side of the mesh cover 21 is connected to the drying cage 2 by a lock; rotating shafts 22 are provided at both ends of the drying cage 2.

[0040] The drying cage 2 is designed as a prismatic mesh cage or a cylindrical mesh, which is conducive to the free circulation of hot air in the sample and improves the drying efficiency. At the same time, the mesh structure also facilitates the rapid discharge of evaporated water in the sample, reducing the drying time.

[0041] Drying cage 2 has an opening on one side to facilitate sample loading and unloading. A mesh cover 21 is hinged to the opening, allowing for easy opening and closing. A lock latch secures the mesh cover 21 to the drying cage 2 on the other side, ensuring it remains closed during the drying process to prevent sample spillage.

[0042] Rotating shafts 22 are provided at opposite ends of the drying cage 2 , and the rotating shafts cooperate with the supporting base 5 inside the processing box 1 , so that the drying cage 2 can rotate under the drive of the driving member 6 .

[0043] The combination of the mesh structure and the rotating motion enables the hot air to fully contact the sample and remove moisture, thereby significantly improving the drying efficiency.

[0044] The mesh structure and removable parts make cleaning and maintenance easier and more efficient.

[0045] like Figure 2 and 3 As shown, the support seat 5 in this embodiment includes a mounting plate 51 relatively arranged inside the chamber 4, and a support block 52 is arranged between the two mounting plates 51. The support block 52 is U-shaped, and the rotating shaft 22 is rotatably arranged inside the support block 52.

[0046] The mounting plate 51 provides a stable mounting base for the support block 52 and the rotating shaft 22. The U-shaped design of the support block 52 provides the necessary support for the rotating shaft 22 while allowing it to rotate freely within the U-shaped groove. The rotating shaft 22 is a key component connecting the drying cage 2 and the support base 5. It is rotatably mounted within the support block 52, ensuring smooth rotation with the support block 52.

[0047] Parameters such as the diameter, material, and surface treatment of the rotating shaft 22 need to be determined according to the weight, rotation speed, and load requirements of the drying cage 2 .

[0048] In one embodiment, Figure 2 and Figure 4 As shown, the drive member 6 includes a reducer 61 mounted on the processing box 1 and a drive motor 62 mounted on the reducer 61. The output shaft of the drive motor 62 is connected to the input shaft of the reducer 61. The output shaft of the reducer 61 extends into the interior of the chamber 4. One end of the rotating shaft 22 on one side passes through the mounting plate 51 and extends outward. The output shaft of the reducer 61 and the end of the rotating shaft 22 on one side that extends outward are both provided with a transmission wheel 63. The two transmission wheels 63 are in contact with each other. The mounting plate 51 is provided with a groove for the extension of the rotating shaft 22.

[0049] The reducer is used to reduce the output speed of the drive motor 62 and increase the torque to meet the rotation requirements of the drying cage 2. The drive motor 62 provides the rotational power. The output shaft of the reducer 61 extends into the chamber 4 to establish a transmission connection with the rotating shaft 22. The two transmission wheels 63 fit together, transmitting power through friction. The mounting plate 51 has a groove for the rotating shaft 22 to extend, ensuring smooth and unimpeded rotation.

[0050] When the drive motor 62 is started, its power is transmitted to the output shaft through the reducer 61. The transmission wheel 63 on the output shaft rotates accordingly, and the transmission wheel 63 on the rotating shaft 22 transmits power by abutting against the transmission wheel 63. The rotating shaft 22 rotates under the drive of the transmission wheel 63, which in turn drives the drying cage 2 to rotate.

[0051] In another embodiment, the output shaft of the reducer 61 and one end of the rotating shaft 22 extending outward are provided with gears that mesh with each other.

[0052] When the drive motor 62 is started, power is transmitted to the gear on the output shaft through the reducer 61. The gear on the output shaft meshes with the gear on the rotating shaft 22, accurately transmitting power to the rotating shaft 22. Driven by the gear, the rotating shaft 22 rotates, which in turn drives the drying cage 2 to rotate.

[0053] The intermeshing gears can ensure the synchronization and stability of rotation, reducing vibration and noise.

[0054] Specifically, in this embodiment, two supporting plates 9 are relatively provided inside the chamber 4 , and the supporting plates 9 are L-shaped. The tray 11 is arranged above the two supporting plates 9 .

[0055] The design of the L-shaped support plate 9 provides a stable support base for the tray 11, effectively preventing the tray from shaking and tilting during the drying process.

[0056] The tray 11 can be used to receive and dry scattered soil samples and liquids.

[0057] Preferably, in this embodiment, a detachable filter screen 10 is further provided inside the chamber 4, and the filter screen 10 is located above the fan 7. Two blocks are relatively provided inside the chamber 4, and the filter screen 10 is plugged into the two blocks.

[0058] The filter 10 is arranged inside the chamber 4 and above the fan 7. It can effectively prevent dust, impurities and other particles from being sucked into the drying cage 2 by the fan, thereby protecting the soil sample from contamination.

[0059] Specifically, if Figure 5 As shown, the stirring rod 12 in this embodiment includes a second rotating shaft arranged inside the drying cage 2, and a plurality of round rods arranged on the second rotating shaft.

[0060] Rotating shaft 2 is located inside drying cage 2. Rotating shaft 2 rotates with drying cage 2, driving the rods on it to stir the soil sample. During rotation, these rods come into contact with the soil sample inside drying cage 2, stirring it and maintaining a uniform mixture throughout the drying process. This helps improve drying efficiency and ensures uniform heating of the soil sample.

[0061] It should be noted that an air inlet is provided at the bottom of the processing box 1, an exhaust net is provided on the flip cover 3, and the flip cover 3 is made of transparent plastic material.

[0062] An air inlet is provided at the bottom of the processing box 1 for introducing outside air to support the drying process. Fresh air can be drawn into the processing box through the air inlet, and after heat exchange with the soil sample, it removes moisture from the sample and is finally discharged through the exhaust system.

[0063] The flap 3 is provided with an exhaust net, which allows the hot and humid air in the processing box to be discharged. The design of the exhaust net should ensure that it can effectively discharge the gas while preventing external impurities such as dust and insects from entering the processing box.

[0064] The flip cover 3 is made of transparent plastic. This allows workers to visually observe the conditions inside the processing chamber, such as the drying status of the soil sample and the working condition of the stirring rod, without opening the cover. This is important for monitoring the drying process and ensuring safe operation of the equipment.
