Description

Technical Field

[0001] This utility model relates to the field of rock salt production technology, specifically to a rock salt spiral conveying and metering device. Background Technology

[0002] Rock salt, chemically composed of sodium chloride, is a halide belonging to the isometric crystal system, specifically the hexahedral class. Single crystals are cubic, often with step-like depressions on the cubic crystal faces. Aggregates are usually granular or massive. Pure rock salt is colorless and transparent, while impurities result in light gray, yellow, red, or black colors, with a vitreous luster. It has a Mohs hardness of 2-2.5 and a specific gravity of 2.1-2.2. It is readily soluble in water and has a salty taste. Its melting point is 804 degrees Celsius, and its flame test is yellow. Rock salt is a typical chemically sedimentary mineral. Currently, rock salt mining primarily utilizes the water injection dissolution method. After the well is put into operation, water is injected to dissolve the rock salt near the well, forming a brine-filled rock salt cavity. The brine is then pumped to the surface for further treatment, completing one mining cycle.

[0003] For example, CN213711050U discloses a rock salt mining device, including a well pipe and a central pipe. A cover plate is fixedly installed at the top opening of the well pipe, and the surface of the cover plate has a through hole. One end of the central pipe passes through the through hole and is connected to the central pipe. A ring plate is sleeved and fixedly installed on the outer wall of the central pipe near its bottom end. One end of a support rod is fixedly installed on both sides of the lower surface of the ring plate on both sides of the central pipe. A support plate is fixedly installed on the other end of the two support rods. A mechanical box is fixedly installed on the upper surface of the support plate between the two support rods. A drive motor is provided on one side of the lower inner surface of the mechanical box, and the output end of the drive motor is fixedly connected to a first... At one end of the linkage rod, this invention can break up undissolved large chunks of salt or other lumpy impurities through the crushing teeth on the two rods, thereby improving the smoothness of the central tube and the main body and increasing the efficiency of salt mining. However, after rock salt is mined, it is difficult to accurately measure the rock salt during the transportation process, which cannot meet the requirements for precise control of production materials. Some simple metering devices, such as volumetric metering devices, only determine the amount of rock salt by roughly estimating its volume. However, the particle size and bulk density of rock salt are not uniform, which leads to large measurement errors and seriously affects the stability of product quality and the precise control of the production process. Therefore, it is urgent to design a rock salt spiral conveying metering device to solve the above problems. Utility Model Content
