Embodiment Construction
[0014] Such as figure 1 , 2 As shown, the self-cleaning automatic rock freeze-thaw test device of the present invention includes a cabinet with a liquid crystal control panel, and a freeze-thaw test chamber 1, a refrigeration system, a heating system and a control system are arranged in the cabinet.
[0015] The stainless steel freeze-thaw test chamber 1 is equipped with a temperature sensor 2. In order to grasp the temperature conditions in the freeze-thaw test chamber in multiple directions and accurately control the temperature change of the freeze-thaw test chamber, the temperature sensor 2 includes a rock specimen temperature sensor and a freeze-thaw test chamber. Space temperature sensor and freeze-thaw chamber wall temperature sensor. The refrigeration system includes a compressor, an evaporator, a fan, etc., and its cold air outlet 3 is located above the freeze-thaw test chamber 1, and is used to reduce the temperature of the freeze-thaw test chamber 1 to -20±2°C for ...

The invention discloses a self-cleaning rock freezing-thawing automated testing apparatus. The apparatus comprises a box provided with a freezing-thawing testing box body, a refrigerating system, a heating system and a controlling system. A temperature sensor is arranged in the box, a cold air outlet of the refrigerating system is located above the freezing-thawing testing box body. The heating system comprises a water storage tank located below the freezing-thawing testing box body and provided with a first heater. A water inlet and outlet pipeline between the water storage tank and the freezing-thawing testing box body is communicated correspondingly with a water injection pump and a water drainage pump, and a self-cleaning rinsing device is arranged at the bottom of the freezing-thawing testing box body. The apparatus is simple in structure, convenient to use, testing conditions of freezing and thawing in the box are automatically controlled, and personal errors are reduced; heating and cooling are fast, energy consumption for testing is greatly lowered, and testing accuracy is improved; meanwhile, the self-cleaning rinsing device is arranged, water quality and cleanliness of hot water are improved, blocking and damage of a water pump are prevented, and the service life of equipment is prolonged.
Description
technical field [0001] The invention relates to the technical field of rock and soil testing equipment, in particular to a self-cleaning automatic rock freeze-thaw test device. Background technique [0002] The rock freeze-thaw test is mainly used to determine the performance of the rock. Usually, the rock specimen is placed in the "freezing-thawing" temperature cycle change mode that simulates the external environment. After the test, the mass loss rate of the specimen, uniaxial compression resistance The strength and freeze-thaw coefficient are used to evaluate rock properties. The specific steps of the freeze-thaw experiment are: freeze the iron container containing the test piece at -20±2°C for four hours, then take out the iron container, pour water into the iron container to immerse the test piece, and keep the water temperature at 20±2°C. 2°C, continuous thawing for four hours is a freeze-thaw cycle; every time a cycle is performed, check whether there are pieces or ...
