Abstract

The invention discloses an efficient low-amplitude energy-saving dewatering screen which comprises supporting legs, a screen body with a screen mesh at the bottom is elastically supported on the supporting legs, a primary recycling water tank connected to the supporting legs is arranged below the screen body, two sets of water-cooling shock excitation units arranged side by side are arranged on the screen body, and one side of the primary recycling water tank is connected with a slurry pump driven by a motor. The slurry pump is connected with a cyclone arranged above the screen body through a pipeline, an overflow port of the cyclone is communicated with a secondary recovery water tank fixed on the screen body through a pipeline, the bottom of the secondary recovery water tank is communicated with a blow-off pipe leading to the primary recovery water tank, and the outer wall of the upper end of the secondary recovery water tank is communicated with a clear water pipe; according to the invention, the overall treatment efficiency is improved; and meanwhile, the service life of the water-cooled vibration exciter is prolonged, and the maintenance frequency is reduced.

Description

technical field [0001] The invention belongs to the technical field of dewatering screens, and relates to a high-efficiency, low-amplitude, energy-saving dewatering screen. Background technique [0002] Dewatering screen is a kind of vibrating screen. Its main functions are dehydration, desliming and de-intermediation. It can be used for sand washing in sand and gravel plants, coal slime recovery in coal preparation plants, and dry discharge of tailings in mineral processing plants. Therefore, it is also called sand dewatering screen. , Mine dewatering screen, coal slime dewatering screen, tailings dry discharge screen, high frequency dewatering screen, etc. [0003] The existing dewatering screen consists of a screen box, a vibration exciter, a support system and a motor. The two unconnected exciters are driven by the tape coupling to run synchronously and reversely. The centrifugal force generated by the two sets of eccentric masses along the vibration direction is superi...
