Embodiment Construction
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0025] The invention is a large-capacity energy-saving and environmental-friendly equipment suitable for drying soil samples of geochemical tests. Large volume oven based on air energy heat pump as heat source blasting. The soil is dried at low temperature at a temperature of 45±5°C. The oven is divided into multiple drying chambers, and the drying chambers are connected by switchable air ducts. It solves the problems of large energy waste and high cost in the natural air drying process of large quantities of soil samples;

The invention relates to a high-capacity low-temperature soil drying box which solves the problems of long time consumption, large energy waste and high cost in the natural air drying process of a large batch of soil samples in the prior art. The heat pump chamber and the drying chamber are communicated through an air inlet and an air outlet, the lower left portion of the heat pump chamber is divided into a compressor chamber through a partition plate, a layer of partition plate is arranged in the middle of the heat pump chamber, and the left end of the middle partition plate is divided into a temperature control chamber through a partition plate; the upper section of the air duct is provided with a fan, the upper section of the air duct is connected with the air inlet of the drying chamber, the lower section of the air duct is connected with the air outlet of the drying chamber, the evaporator is arranged at the lower section of the air duct, and the right side of the evaporator is provided with the air outlet of the drying chamber; the compressor is connected with a condenser inlet; a condenser outlet is connected with an expansion valve and an evaporator inlet; the drying chamber is composed of a plurality of small drying chambers.
Description
Technical field: [0001] The invention belongs to the technical field of railway engineering survey and test equipment, and relates to a large-capacity low-temperature soil drying box. Background technique: [0002] With the continuous improvement and advancement of the national railway network planning, there are more and more railway survey projects, and the number of geochemical tests in the survey test has also increased accordingly. However, with the improvement of various survey techniques and the accumulation of experience, the survey cycle is also continuously reduced. In the process of exploration, the test period of geotechnical chemistry is also required to be shorter and shorter. In the course of geochemical testing, air-dried samples are required for the analysis of the samples. It takes a long time for the sample to air-dry. There are two drying methods in the test specification, one is to dry in a cool and ventilated place; the other is to dry in an oven at ...
