TECHNICAL FIELD
[0001] The utility model relates to core drying technical field, specifically, relate to an intelligent core drying device. BACKGROUND
[0002] Core sampling, also known as core drilling sampling, is a sampling work performed on cores or mineral cores obtained by drilling. It generally splits the core into two halves or four parts along the long axis according to a certain sampling length by manual or mechanical method, and then takes one half or one quarter as a sample.
[0003] In the determination experiment of physical parameters such as porosity, permeability and particle size of rock sample, core cleaning and core drying must be performed on the core to remove crude oil, water and their solubles in the core, and to reduce their influence on the determination of physical parameters. Core drying is performed by a core dryer. The common core dryer usually places the core on a placing plate, generates heat through a heating pipe, and cooperates with a wind guide device to keep the temperature of the dryer below 105 DEG C for about 8 hours. However, the common dryer causes the bottom of the core to contact the placing plate, and cannot uniformly heat the core. At the same time, the core dryer cannot accurately control the drying time. If the drying time is insufficient, water still exists in the core. If the drying time is too long, power and time are consumed, and certain safety hazards may be caused due to the long-time overload operation of the dryer.

The signal transmission line 6 serves two purposes: firstly, it transmits the humidity value collected by the humidity sensor 9 to the external computer control device 7 to determine whether drying is complete; secondly, it transmits the control command signal issued by the computer control device 7 to the drying chamber 5 to complete the start and stop operation of the drying chamber. The drying mechanism 11 consists of two layers: the lower layer is a base plate with an air duct 16 arranged on top to generate airflow and deliver heat; the upper layer is a fixed frame with heating pipes 17 arranged on it to generate heat, which is then evenly delivered into the chamber through the lower air duct 16.
