Description

TECHNICAL FIELD

[0001] The utility model relates to sandstone dewatering and impurity removal production technical field, especially to a dewatering screen. BACKGROUND

[0002] The dewatering screen is mainly used for dewatering, desliming and medium removal, and can be used for washing sand in sandstone plants, coal slime recovery in coal preparation plants, tailing dry discharge in ore dressing plants and the like, and is also called sandstone dewatering screen, mine dewatering screen, coal slime dewatering screen and tailing dewatering screen. The tailing dewatering screen is also called tailing dry discharge screen. In addition to various excellent performances and functions of the ordinary dewatering screen, the tailing dry discharge screen is matched with a thickener for tailing dry discharge, and is the best dewatering screen and tailing dry discharge equipment at present. Although they belong to the same dewatering equipment, the structures of the dewatering screens are different when they are used for different materials. For example, the sandstone dewatering screen on the sand washing production line and the tailing dewatering screen commonly used in ore dressing plants are different equipment. The dewatering screens on the market at present mainly use the vibration of the vibration motor to make the dewatering screen move at high frequency, so that the water leaks from the screen plate. However, some small particles are difficult to remove. The screen plate is directly in contact with the sandstone, and is seriously worn after a long time of operation. The surface is slippery, and it is difficult to form a friction force on the surface of the sandstone, so that the sandstone cannot be turned over, and the effect is not good. The screen plate is generally fixedly installed in the vibrating screen seat and cannot be taken out for reprocessing.

[0003] The prior art patent CN209033905U discloses a dewatering screen used in sandstone plants, which comprises a supporting leg, a bottom plate fixedly installed at the top of the supporting leg, a fixed column fixedly connected to the top of the bottom plate, a spring movably sleeved on the outer side of the fixed column, an active column movably sleeved at the other end of the spring, a supporting seat fixedly installed at the top of the active column, a vibrating screen seat fixedly installed at the top of the supporting seat, and a fixed plate fixedly installed at the bottom of the vibrating screen seat. The feeding plate extends into the circular screen mesh without contacting, so that the material can be fed into the circular screen mesh during the rotation of the circular screen mesh. The rotation of the circular screen mesh can make the water and small particles in the sandstone flow out of the circular screen mesh. The water flows downward to the sewer and then flows out of the dewatering cylinder due to the inclined state of the dewatering cylinder. The other large particles of sandstone material enter the next process through the discharge port.

[0004] However, in the above structure, the circular screen mesh has a long filtering channel, which can easily cause blockage, thereby affecting the filtering effect. In addition, the circular screen mesh is not convenient to disassemble, which affects the subsequent cleaning. UTILITY MODEL CONTENTS
