Independent air chamber jigger

Abstract

The invention discloses an independent air chamber jigger which comprises a compressed air source, an air box and a jigging chamber with a screening groove in the top. An air inlet end, an air outletend and an air supply end are arranged on the air box, an air inlet valve is arranged at the air inlet end, an air outlet valve is arranged at the air outlet end, and the compressed air source is connected with the air inlet end through an air pipe. A ventilating pipeline is arranged in the jigging chamber, one end of the ventilating pipeline is blocked, and the other end of the ventilating pipeline extends out of the jigging chamber and is connected with the air supply end through an air pipe. A plurality of independent air chambers are further evenly distributed in the jigging chamber, the tops of the independent air chambers are closed, the bottoms of the independent air chambers are open, deformation diaphragms dividing the independent air chambers into inner air chambers and outer airchambers are arranged in the independent air chambers, and the inner air chambers are communicated with the ventilating pipeline in parallel. According to the independent air chamber jigger, no contact between air and water is realized, water is prevented from being discharged during exhaust to influence the action of the valves, the equipment reliability is improved, the water leakage phenomenonis avoided, the problem of non-uniform transverse pulsating water flow after the equipment is large-scale is solved, and the sorting effect is improved.

Description

technical field [0001] The invention relates to a jig, in particular to a jig with an independent air chamber. Background technique [0002] At present, jig machines used at home and abroad generally use fixed air chambers, which are divided into screen side air chambers, under-screen air chambers and compound air chambers. They all use the principle of U-shaped tubes. figure 1 The sieve side (side drum type) air chamber jig machine air exerts pulsating pressure from one side of the U-shaped pipe (air chamber side) on one side of the U-shaped pipe, and obtains pulsating rising water flow on the other side (jigging chamber side) , The rising water flow passes through the sieve plate agitating sieve, so that the materials on the sieve plate agitating sieve are loosened, so that the materials are layered according to the density, so as to achieve the purpose of separation. figure 2 The under-screen air chamber jig machine deforms the U-shaped tube, and the air chamber is inst...

Problems solved by technology

If the height of the air chamber is too small, the longitudinal wave height distribution of the sieve plate will be uneven, and the air pressure will be too high, and the air will burst out of the air chamber to destroy the bed layer; if the height of the air chamber is too high, the static pressure loss of the water flow will also increase, which will affect the stratification effect ;When the air chamber is exhausted for too long, the air chamber will be submerged or even the water will be discharged. Therefore, the common disadvantage of ordinary jigs is that there must be air and water in contact to form an interface between water and air, so that the air discharged through the exhaust valve Inevitably, there will be water, causing the air valve to spray water, affecting the action of the valve, reducing the reliability of the equipment, and at the same time, water leakage occurs, resulting in waste of water resources; in addition, when the equipment is large-scale, the horizontal pulsation in the jigging chamber Uneven water flow affects the sorting effect
