Technical Field

[0001] The utility model relates to the technical field of soil detection auxiliary equipment, in particular to an adjustable electric sand bath device. Background Art

[0002] The organic matter content in the soil is one of the important indicators to measure the fertility of the soil. To understand the fertility of the soil, the soil organic matter content must be determined. The existing soil organic matter determination method mainly uses oil bath and sand bath as digestion devices. The sand bath heating method is to move the digestion bottle with the soil sample and reagent solution to the preheated electric sand bath for heating, digest the sample, and then remove the digestion bottle from the electric sand bath. The end point is determined by observing the color change during the titration process, and then the experimental data is calculated by the formula to obtain the soil organic matter content.

[0003] In the prior art, a utility model patent with publication number CN220304969U discloses an organic sand bath heating device, which supports and limits the bottle body by setting a limit assembly so that the bottle body is not easy to tip over when heated in the sand bath furnace. A screw rod is set to drive the limit assembly to rise and fall, so that the bottle body can be easily placed in and removed from the sand bath furnace, so that the staff will not be scalded when the heated bottle body is removed. The device has the effects of easy operation and strong practicality.

[0004] However, when the above device is in use, there is a serious heating imbalance phenomenon after the temperature of the sand bath rises. The temperature of the sand at the bottom of the sand bath is too high, while the temperature of the sand on the surface of the sand bath is still very low. The temperature difference between the two parts is too large, resulting in very uneven heating of the specific gravity bottle during the test, and the sample with a high liquid level in the higher bottle cannot be heated evenly, affecting the test effect. Therefore, it does not meet the existing needs. We have proposed an adjustable electric sand bath device. Utility Model Content

On both sides inside the sand bath furnace 1, a flipping mechanism 2 is provided. In the middle inside the sand bath furnace 1, a sand piling mechanism 3 is provided. The sand piling mechanism 3 includes four lead screws 306. Threaded blocks 307 are sleeved on the outer surfaces of the lead screws 306. An arc-shaped plate 301 is arranged above the threaded blocks 307. An arc-shaped bent plate 302 is installed on the upper end surface of the arc-shaped plate 301. A baffle 305 is installed on one side of the outer surface of the arc-shaped plate 301. On the opposite sides of the outer surfaces of the four arc-shaped plates 301, heat conducting rods B304 are provided. A heat conducting rod A303 is arranged on the upper end surface of the heat conducting rod B304. Heat conducting layers 309 are arranged on the inner sides of the heat conducting rod A303 and the heat conducting rod B304.

[0024] As Figure 2 and Figure 3 As shown in the figure, further, on the opposite sides of the outer surfaces of the four lead screws 306, a limiting plate 308 is rotatably connected through bearings. The limiting plate 308 is connected to the bottom surface of the sand bath furnace 1 through a vertical rod. A through groove is arranged on the lower end surface of the arc-shaped plate 301. The inner wall of the through groove is fixedly connected to the outer surface of the threaded block 307. Motors A are installed in the front, rear, left, and right inside the sand bath furnace 1 through motor cavities. The output end of the motor A is fixedly connected to a short shaft. The other end of the short shaft is fixedly connected to one end of the lead screw 306. The thread directions of the front-rear and left-right two lead screws 306 are opposite. When the motor A works, it can drive the short shaft to rotate, thereby driving the lead screw 306 to rotate, driving the four threaded blocks 307 to move simultaneously in the direction of approaching or separating, thereby driving the four arc-shaped plates 301 to move simultaneously in the direction of approaching or separating.

[0025] The flipping mechanism 2 includes a stirring shaft 202. Four sand turning blades 201 are evenly installed on the outer surface of the stirring shaft 202. Motors B are installed on both sides in the front of the inside of the sand bath furnace 1 through cavities. The output end of the motor B is fixedly connected to the front end surface of the stirring shaft 202 through a coupling. The rear end surface of the stirring shaft 202 is rotatably connected to the inner wall of the sand bath furnace 1 through a bearing. When the motor B works, it can drive the stirring shaft 202 to rotate, thereby driving the sand turning blades 201 to drive the surrounding sand to flip, so that the sand can be evenly heated.

[0026] As Figure 4 As shown in the figure, the heat conducting rod A303 and the heat conducting rod B304 are of an integral structure.

Graphene has a very high thermal conductivity and heat conducting performance, and can transfer the heat of the sand with a higher temperature at the bottom to the upper part, shortening the heating time.

[0027] Working principle: When in use, first connect the power supply. By turning on motor B, the rotation of motor B can drive the stirring shaft 202 to rotate, thereby driving the foundry blades 201 to drive the surrounding sand to flip, turning the hotter sand below to the upper part, so that the sand is evenly heated. When the bottle to be heated is relatively tall and the liquid level of the sample in the bottle is relatively high, after the bottle is placed in the middle inside the sand bath furnace 1, the switch of motor A can be controlled. The operation of motor A drives the short shaft to rotate, thereby driving the lead screw 306 to rotate, driving the four threaded blocks 307 to move towards each other at the same time, thereby driving the four arc-shaped plates 301 to move towards each other at the same time, pushing the sand towards the bottle. And the baffle 305 will block the gap between every two adjacent arc-shaped plates 301 to prevent the sand from slipping through the gap. And by providing the heat conducting rod A 303 and the heat conducting rod B 304, graphene has very high thermal conductivity and heat conduction performance. The heat conducting rod B 304 can transfer the heat of the hotter sand at the bottom to the heat conducting rod A 303, and the heat conducting rod A 303 then transfers the heat to the sand above, increasing the temperature of the sand above, making the bottle evenly heated, and shortening the heating time. This utility model can flip the sand to make the sand evenly heated, and by providing the sand stacking mechanism 3, it can evenly heat samples with different liquid levels, improving the applicability.
