Description

Technical Field

[0001] This utility model relates to the field of soil sample drying technology, and in particular to a hot air drying device for soil samples. Background Technology

[0002] In the field of environmental monitoring, the moisture content of soil samples is a test item. Removing excess moisture from soil samples is a crucial pretreatment step. Oven drying can quickly and effectively remove moisture under well-controlled temperature conditions and ensure the consistency of experimental conditions, so it is widely used in laboratories.

[0003] A soil sample drying device with publication number CN219121863U includes a main body. Three sets of sliding grooves are symmetrically fixed to both sides inside the main body. Sliding blocks are slidably connected inside the sliding grooves. A drying trough is fixed to one side of two sets of sliding blocks that are close to each other. A turning component that can turn the soil during the drying process is installed on the top of one side of the main body. A drying component that can dry the soil is installed in the middle of the top of the main body. The device can simultaneously dehumidify the soil by blowing hot air and dehumidifying air, which reduces the time required for dehumidification and thus improves the drying efficiency of the device.

[0004] The aforementioned soil sample drying device can turn the soil during the dehumidification process, making the dehumidification more uniform and thus improving the drying effect of the device. However, the turning of the soil by rotating the rotating rod and driving the turning plate is not thorough and comprehensive, which affects the drying efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient and incomplete soil turning, which affects drying efficiency, and to propose a hot air drying device for soil samples.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a hot air drying device for soil samples, including a box body. The front end of the box body has several slots. The inside of the slots is equipped with a frame through a guide component. A sealing cover is installed on the top of the frame. An elastic membrane is fixedly installed inside the frame. A tapping component is installed at the bottom of the elastic membrane. Ventilation slots are provided on both sides of the frame, and filter plates are fixedly installed inside the ventilation slots. A drying component connected to the ventilation slots is installed on the top of the box.

[0007] Furthermore, the guide assembly includes a pair of trays fixedly installed on the inner wall of the box, and the top of the trays is slidably connected to the frame. Each of the pair of trays is fixedly connected to a vertical plate, and the pair of vertical plates are located on both sides of the frame.

[0008] Furthermore, the striking assembly includes a mounting plate fixedly installed on the inner wall of the housing, a rotating shaft rotatably mounted on the top of the mounting plate via a pair of bearing seats, a plurality of striking plates fixedly installed on the outer wall of the rotating shaft, and a drive assembly connected to the rear end of the rotating shaft.

[0009] Furthermore, the drive assembly includes a motor fixedly mounted on a mounting plate, pulleys fixedly mounted at the rear ends of two adjacent rotating shafts, and belts fitted on the outer walls of the two pulleys. The output shaft of the motor is connected to a rotating shaft via a coupling.

[0010] Furthermore, the drying assembly includes a hot air blower fixedly installed on the top of the housing, with both ends of the hot air blower connected to pipes via connecting pipes; Both sides of the frame are slidably connected to a connecting pipe aligned with the ventilation slot, and the two connecting pipes are respectively fixedly connected to a pipeline.

[0011] Furthermore, several horizontal plates corresponding to the striking plate are adhered to the bottom of the elastic membrane, and sliders are fixedly connected to both ends of the horizontal plates. A groove is provided on the inner wall of the frame, and the slider is slidably installed inside the groove.

[0012] The present invention provides a soil sample hot air drying device with the following advantages: An elastic membrane is installed inside the frame to support the soil sample. While the soil sample is being dried by circulating hot air generated by a hot air blower, a motor drives several rotating shafts and striking plates on them to strike the horizontal plates. This causes the elastic membranes on the two sets of horizontal plates to alternately bulge upwards, lifting the soil onto them into the air. This process mixes and agitates the soil sample, ensuring more uniform and thorough contact with the hot air, resulting in more even and comprehensive drying, and higher efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 As an embodiment of this utility model, a hot air drying device for soil samples is disclosed, including a box body 1. The front end of the box body 1 is provided with a plurality of slots 11. A frame 3 is installed inside the slots 11 through a guide component 2. A sealing cover 4 is installed on the top of the frame 3. An elastic membrane 5 is fixedly installed inside the frame 3. A striking component 6 is installed at the bottom of the elastic membrane 5. Preferably, a sealing ring is installed on the outer wall of the front end and the top of the frame 3. The front end of the sealing cover 4 is fixedly connected to the box body 1. Ventilation slots 31 are provided on both sides of the frame 3, and a filter plate 7 is fixedly installed inside the ventilation slots 31. A drying component 8 communicating with the ventilation slots 31 is installed on the top of the box 1. Soil samples are poured onto the elastic membrane 5 inside the frame 3, and then the frame 3 is inserted into the box 1 through the slot 11. The upper end of the frame 3 is attached to the sealing cover 4 and sealed by the sealing cover 4, effectively preventing the leakage of hot air and soil. By striking the bottom of the elastic membrane 5 upwards with the striking component 6, the elastic membrane 5 at the striking point deforms and bulges upwards, thereby lifting the soil on the upper surface and briefly suspending it in the air, so that the soil can be mixed and turned over in the process. Hot air is injected into the frame 3 through the drying component 8, so that the hot air comes into full contact with the soil on the elastic membrane 5 and dries the soil.

[0017] For example, the guide assembly 2 includes a pair of trays 21 fixedly installed on the inner wall of the housing 1, and the top of the trays 21 is slidably connected to the frame 3. The top of each pair of trays 21 is fixedly connected to a vertical plate 22, and the pair of vertical plates 22 are respectively located on both sides of the frame 3. When the frame 3 is inserted into the housing 1 through the slot 11, the frame 3 is inserted between the two upright plates 22 and on a pair of support plates 21. The pair of upright plates 22 guide the frame 3 in the left and right directions, and the pair of support plates 21, together with the sealing cover 4, guide and install the frame 3 in the up and down directions.

[0018] It should be noted that the striking component 6 includes a mounting plate 61 fixedly installed on the inner wall of the housing 1. A rotating shaft 64 is rotatably mounted on the top of the mounting plate 61 via a pair of bearing seats 63. A plurality of striking plates 65 are fixedly installed on the outer wall of the rotating shaft 64. A driving component 9 is connected to the rear end of the rotating shaft 64. Preferably, the plurality of striking plates 65 are divided into two groups, and the two groups of striking plates 65 are symmetrically and alternately mounted on the rotating shaft 64. The drive component 9 drives the rotating shaft 64 to rotate, thereby driving the two sets of striking plates 65 to rotate, so that the two sets of striking plates 65 alternately strike the elastic membrane 5, causing the elastic membrane 5 to deform and bulge upward.

[0019] Furthermore, the drive assembly 9 includes a motor 91 fixedly mounted on the mounting plate 61, pulleys 92 fixedly mounted on the rear ends of two adjacent rotating shafts 64, and belts 93 sleeved on the outer walls of the two pulleys 92. The output shaft of the motor 91 is connected to a rotating shaft 64 through a coupling. Preferably, the upper end face of the mounting plate 61 is provided with a through hole for the belt 93 to pass through. Motor 91 drives a rotating shaft 64 to rotate via a coupling. The rotating shaft 64 drives other rotating shafts 64 to rotate in sequence via belt 93 and pulley 92, thereby improving the efficiency of one motor 91 driving all rotating shafts 64 to rotate.

[0020] It should be noted that the drying assembly 8 includes a hot air blower 81 fixedly installed on the top of the housing 1, and both ends of the hot air blower 81 are connected to the pipe 83 through the connecting pipe 82. Both sides of the frame 3 are slidably connected to a connecting pipe 84 aligned with the ventilation slot 31, and the two connecting pipes 84 are respectively fixedly connected to the pipe 83. Preferably, a sealing ring is installed at the end of the connecting pipe 84 near the frame 3. After the frame 3 is inserted, the ventilation slot 31 is aligned with the connecting pipe 84. The hot air is heated and transported by the hot air blower 81. The generated hot air is injected into the pipe 83 through the connecting pipe 82. The hot air then passes through several connecting pipes 84, enters the frame 3 through the ventilation slot 31, dries the soil sample, and carries away the moisture. It passes through the filter plate 7 in the ventilation slot 31 on the other side. After the soil particles are filtered out, they enter the pipe 83 on the other side through the connecting pipe 84 on the other side, and then return to the hot air blower 81 through the connecting pipe 82 on the other side for reheating to restore stability and drying effect.

[0021] In some embodiments, a plurality of horizontal plates 10 corresponding to the striking plate are bonded to the bottom of the elastic membrane 5, and sliders 13 are fixedly connected to both ends of the horizontal plates 10. A groove 12 is provided on the inner wall of the frame 3, and the slider 13 is slidably installed inside the groove 12. Preferably, the groove 12 is a dovetail groove. By attaching a horizontal plate 10 to the bottom of the elastic membrane 5, the striking plate 65 strikes the horizontal plate 10, causing the slider 13 to slide upward in the groove 12, which in turn pushes the horizontal plate 10 upward, thereby pushing the elastic membrane 5 above the horizontal plate 10, which is the same width as the elastic membrane 5, upward and increasing the soil turning area.

[0022] Working method: Pour the soil sample onto the elastic membrane 5 inside the frame 3, and then insert the frame 3 into the box 1 through the slot 11; The motor 91 drives several rotating shafts 64 to rotate via belt 93 and pulley 92, thereby driving two sets of striking plates 65 at the bottom of several frame 3 to rotate upward and strike the horizontal plate 10. This causes the two sets of alternately arranged horizontal plates 10 located on the two sets of striking plates 65 to deform and bulge the elastic membrane 5 upward, thereby lifting the soil on the upper surface and briefly suspending it in the air, so that the soil can be mixed and turned over in this process. The hot air is heated and transported by the hot air blower 81. The generated hot air is injected into the pipe 83 through the connecting pipe 82. The hot air then passes through several connecting pipes 84, passes through the ventilation slot 31, and enters the frame 3 to dry the soil sample. The air also carries away the moisture and passes through the filter plate 7 in the ventilation slot 31 on the other side. After the soil particles are filtered out, they enter the pipe 83 on the other side through the connecting pipe 84 on the other side, and then return to the hot air blower 81 through the connecting pipe 82 on the other side for reheating to restore stability and drying effect.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
