Description
Technical Field
The utility model belongs to the technical field of ore dressing screening machinery, concretely relates to can be in multistage water sieve screening machine of a plurality of size fraction products of aquatic screening and output.
Background
The screening equipment such as the fine screen and the linear vibrating screen is used as the grading equipment and is widely applied to the mineral separation industry. When fine sieves are used for screening, ore pulp is fed to the surface of the sieve, and ideally, particles larger than the sieve mesh are discharged from the tail end of the surface of the sieve on the sieve to become oversize products, and particles smaller than the sieve mesh are discharged from the undersize products through the surface of the sieve to become undersize products. However, in practice, because the screening process is performed in an air medium, and due to the ore pulp concentration, the installation angle of the screen surface, the size of the screen holes and the like, the product on the screen usually contains a lot of particles smaller than the size of the screen holes, and the particles are remained on the screen due to the failure of effective screening, so that the product on the screen becomes the product on the screen, and the screening efficiency is affected.

The existing water sieve equipment is named as the invention patent application of a water sieve screening machine with the application number of CN201710750688.9 and the invention patent application of a multilayer water sieve screening machine with the application number of CN201710749978.1, and although the two types of fine sieve equipment realize the screening process of ore pulp in a water medium, the screening efficiency is improved. However, the integrated ore feeding and discharging pipes of the two types of fine screening equipment are of a double-pipe sleeved structure, ore is fed through the inner pipe, ore is discharged through the annular cavity between the outer pipe and the inner pipe, and the annular cavity is also internally provided with the small ore feeding pipes of four layers, so that the problem of ore pulp blockage is easily caused by the structure, especially when the impurity content in the ore pulp is high, the normal work of the equipment is influenced, and the maintenance is inconvenient.
In addition, the fine screening and water screening devices can only separate the particles in the ore pulp into two grades of products with the granularity of the upper screen and the lower screen during operation, and cannot obtain the products with multiple granularity grades. Therefore, in a concentrating mill, products with a plurality of granularity levels are needed so as to meet the requirements of grading and optimizing materials with a plurality of levels, screening equipment with different screen hole sizes needs to be arranged, and a large amount of factory building area needs to be occupied. Therefore, it is necessary to develop a fine screening apparatus which has high screening efficiency, small floor space and can produce products of various grain size grades.
