The pre-evaporation area 220 and the dehumidification evaporation area 240 are both provided with There is an electric heating evaporation plate 250 and a water immersion cylinder 260 is set at the test area 230. The side wall of the circular cover 100 is provided with a discharge port 110 corresponding to the loading and unloading area 210. The rotating conveying mechanism 300 includes a supporting rotating shaft 500, a supporting component 700, a pressing component 800 and a downward cylinder part 900. The supporting rotating shaft 500 is rotatably arranged at the center of the circular cover 100 and the top of the supporting rotating shaft 500 is connected to the conveying motor 510 arranged at the top of the circular cover 100. The supporting component 700 is slidably arranged on the supporting rotating shaft 500 and a plurality of material placing cylinder assemblies 400 are circumferentially mounted on the supporting component 700. The material placing cylinder assemblies 400 rotate with the supporting component 700 and sequentially pass through the loading and unloading area 210, the pre-evaporation area 220, the testing area 230 and the dehumidification evaporation area 240; the pressing component 800 is located on the upper side of the supporting component 700 and is connected to the downward moving cylinder part 900 arranged on the top of the circular cover shell 100; the pre-evaporation area An upper pressure cover component 600 is arranged on the upper side of 220, the test area 230 and the dehumidification evaporation area 240, and the upper pressure cover component 600 can cover the top port of the material placing cylinder assembly 400, and the upper pressure cover component 600 is connected to the lower pressure component 800; a water accumulation condenser 270 is arranged at the bottom of the test table 200, and the water accumulation condenser 270 has a plurality of condensation liquid accumulation cavities, and the plurality of condensation liquid accumulation cavities are respectively connected with the immersion cylinder 260 and the two upper pressure cover components 600 located on the upper side of the electric heating evaporation plate 250.

[0027] In the embodiment of the present invention, the geological sample block to be tested can be placed in the material placement barrel assembly 400 at the loading and unloading area 210 from the placement port 110, the conveying motor 510 works and drives the supporting rotating shaft 500 to rotate, the supporting rotating shaft 500 drives the supporting component 700 to rotate, and the supporting component 700 drives the material placement barrel assembly 400 to rotate, and the material placement barrel assembly 400 rotates intermittently in turn through the loading and unloading area 210, the pre-evaporation area 220, the test area 230 and the dehumidification evaporation area 240; when the material placement barrel assembly 400 rotates to the pre-evaporation area 220, the test area 230 and the dehumidification evaporation area 2 40, the conveying motor 510 stops working and the downward cylinder part 900 starts working, the downward cylinder part 900 drives the downward pressure component 800 to move downward, and the upper pressure cover component 600 connected to the downward pressure component 800 gradually covers the top port of the material placing cylinder assembly 400. After the upper pressure cover component 600 covers the top port of the material placing cylinder assembly 400, the downward pressure component 800 continues to move downward and the downward pressure component 800 pushes the supporting component 700 to move downward, and the material placing cylinder assembly 400 moves downward with the supporting component 700; the bottom port of the material placing cylinder assembly 400 on the upper side of the pre-evaporation area 220 is covered on the electric heating evaporation plate 250, and the electric heating evaporation plate 250 is covered. The evaporation plate 250 starts to work and generate heat. The electric heating evaporation plate 250 heats the geological sample block inside the placing cylinder assembly 400 and the temperature of the geological sample block increases. The geological moisture in the pores inside the geological sample block evaporates, so that the geological moisture is introduced into the condensation liquid cavity inside the water accumulation condenser 270 through the upper pressure cover component 600. In this way, the moisture contained in the geological sample block can be measured; when the placing cylinder assembly 400 on the upper side of the test area 230 gradually moves downward, the bottom of the placing cylinder assembly 400 gradually covers the outside of the immersion cylinder 260 and the geological sample block inside the placing cylinder assembly 400 is immersed in the immersion cylinder 260. In the water of the immersion cylinder 260, the initial liquid level of the immersion cylinder 260, the liquid level when the geological sample block is completely immersed in the water, and the liquid level inside the immersion cylinder 260 after the geological sample block is removed from the water are measured. The difference between the initial liquid level of the immersion cylinder 260 and the liquid level inside the immersion cylinder 260 after the geological sample block is removed from the water represents the volume of water taken away by the geological sample block, which can roughly represent the pore volume inside the geological sample block. The difference between the liquid level inside the immersion cylinder 260 after the geological sample block is removed from the water and the liquid level when the geological sample block is completely immersed in the water represents the surface volume of the entire geological sample block.The bottom port of the material placement cylinder assembly 400 in the dehumidification evaporation area 240 is covered on the electric heating evaporation plate 250, and the electric heating evaporation plate 250 starts to work and generates heat. The electric heating evaporation plate 250 heats the geological sample block inside the material placement cylinder assembly 400, and the temperature of the geological sample block increases. The test water in the pores inside the geological sample block evaporates by heat, so that the test water is introduced into the condensation liquid cavity inside the water accumulation condenser 270 through the upper pressure cover component 600. The water accumulation condenser 270 liquefies the water in the condensation liquid cavity and re-introduces it into the immersion cylinder 260, so that it can be reused; in this way, the volume of the geological sample block, the comprehensive volume of the internal pores, and the geological water contained in the geological sample block can be effectively tested, and the test is accurate and easy to operate. ;
