Full automatic vibrating fine screen allowing water spraying

Abstract

The invention relates to a full automatic vibrating fine screen allowing water spraying. A screen body is formed by a left end plate, a right end plate and a middle plate; the screen body is fixed on a supporting frame through a support and a drawing arm; an upper hopper is fixed on the screen body; a screen mesh is fixed on an excitation system which is installed on bilateral sides of the screen body; a transmission device is fixed on the middle plate which is arranged at a middle position of the screen body; the transmission device is formed by a cycloidal pin gear speed reducer, a sliding plate, a screw rod, a nut, a sliding bar, a bearing base and a coupler; the cycloidal pin gear speed reducer drives the screw rod to rotate through the coupler; two ends of the screw rod are fixed through the bearing seat to drive the nut to horizontally move; the sliding plate is installed at the lower end of the screw rod; the bearing seat is fixed on the sliding plate; the sliding bar is installed at the bottom of the nut; a water spraying pipe is connected with the nut; a protective cover is installed at a position from the water spraying pipe bottom to the nut upper portion. The full automatic vibrating fine screen allowing water spraying has the advantages of enabling a screen to vibrate due to the excitation system, enabling the water spraying pipe to perform circulating or discontinuous linear water spraying motions due to the transmission device, being convenient to operate, low in cost and water saving, enabling materials not to block holes and being applied to mine material fine screen industries.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing for screening materials, and relates to a fully automatic water-spraying vibrating fine screen, which is especially suitable for the classification, dehydration, and desliming of fine-grained materials in industries such as ore dressing, coal, building materials, and chemical industry. Background technique [0002] Because many iron ore factories are built in water-poor areas, it is difficult to get water. Generally, vibrating screens consume a lot of water. Generally, high-frequency screens often cause the problem of screen material plugging, which requires a large amount of water for washing, resulting in high production costs. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fully automatic water spray vibrating fine screen, which uses an excitation system to promote the vibration of the ...
