Description

Technical Field

[0001] This utility model relates to the field of rock powder drying technology in hydrogeological exploration, specifically to a device for rapidly drying rock powder. Background Technology

[0002] During the grouting treatment and modification of specific aquifers, it is often necessary to analyze the composition of the rock powder generated from the borehole to accurately determine whether the current drilling layer is the target limestone stratum. Rock powder extracted from the borehole usually carries a large amount of moisture. If it is not dried effectively and promptly, it will clump together, increasing the error in composition analysis. This is especially true in thin limestone layers, where, due to the thinness of the limestone layer, delayed or inaccurate rock powder analysis can easily cause the borehole to deviate from the target layer, entering coal seams or mudstone / sandstone strata, thus affecting the treatment effect.

[0003] In current rock powder processing, natural air drying or simple heating drying methods are commonly used. Natural air drying is greatly affected by the weather; in rainy weather, the rock powder drying cycle is significantly extended, severely slowing down the construction progress. Simple heating drying equipment often lacks temperature and humidity control; excessively high temperatures can easily cause some components in the rock powder to deteriorate, affecting the accuracy of subsequent analysis, while excessively low temperatures result in low drying efficiency.

[0034] Specifically:

[0035] like Figure 1 As shown, in the above embodiment, preferably, the chamber body 1 is cylindrical and the chamber cover 2 is conical, with the larger diameter end of the chamber cover 2 matching the outer diameter of the chamber body 1; a handle 2-1 is provided on the top of the chamber cover 2. To achieve a seal between the chamber cover 2 and the chamber body 1, a sealing element is provided at the contact point between the chamber body 1 and the chamber cover 2. In this embodiment, the sealing element is a sealing strip 13 with an H-shaped cross-section, which is arranged around the upper edge of the chamber body 1 or around the lower edge of the chamber cover 2. Taking the sealing strip 13 being arranged around the upper edge of the chamber body 1 as an example, the lower groove of the H-shaped sealing strip 13 is arranged around the upper edge of the chamber body 1. When the chamber cover 2 is placed over the upper part of the chamber body 1, the lower edge of the chamber cover 2 is fitted into the upper groove of the H-shaped sealing strip 13, thereby achieving a sealed connection between the chamber cover 2 and the chamber body 1.
