Description

Technical Field

[0001] The invention belongs to the field of ore dressing, and in particular relates to an unpowered sand-water separation river sand iron separation device. Background Art

[0002] Chinese Patent 2016213724951 was applied for by Zhu Jinyan (legal representative of the applicant) on December 14, 2016, which discloses a river sand magnetic separator, including a platform, a magnetic separation device arranged on the platform and a turbine device, wherein the turbine device includes a housing, a turbine shaft arranged in the housing, turbine blades arranged on the turbine shaft, a river sand inlet arranged at the upper part of the housing, and a river sand outlet arranged at the lower part of the housing, and the magnetic separation device includes a drive shaft, and the turbine shaft and the drive shaft are connected by a transmission mechanism. The sand pump outlet pipe is connected to the river sand inlet, and the river sand enters the turbine device to impact the turbine blades, and the turbine blades drive the turbine shaft to rotate, and the turbine shaft drives the drive shaft to rotate through the transmission mechanism, and the drive shaft drives the permanent magnetic turntable to rotate, and the river sand flows out from the river sand outlet and passes through the magnetic separation device, and the magnetic separation device recovers the iron therein. Using sand extraction from the sand field as a power source, no additional power is required, energy saving and environmental protection can be achieved, and good economic benefits can be generated.

[0003] However, the conditions of sand fields are different across the country. Some sand fields have a lot of large impurities in the river sand. The applicant has added the impurity removal function based on the above patent technology, forming the technical content recorded in Chinese patents 201921589155.8 and 201910902391.9. Some sand fields have a lot of mud in the river sand, and it is necessary to separate the mud and water in the river sand. At present, sand fields usually pump sand and water onto the screen plate to separate sand and mud and water. If these sand fields directly use the above patent technology for iron selection, the subsequent sand and mud cannot be separated by the current method. Some sand fields have large sand grains, and iron ore is combined with sand grains. The iron ore grade obtained by iron selection using the above patent is very low, and further crushing and iron selection are required to obtain iron concentrate. The water content of the sand extracted from some sand fields is very high. The impact formed by directly entering the magnetic separation equipment is large, which will cause partial loss of iron ore, and it is not easy to separate sand and water later. Summary of the invention

[0004] The technical problem to be solved by the present invention is the separation of sand and water and the adaptation of unpowered river sand iron selection to sand fields with different conditions.
