Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mine equipment, and particularly relates to a diaphragm type mineral separation jig. BACKGROUND

[0002] The diaphragm type jig mainly generates pulsating water flow through the reciprocating movement of the diaphragm to separate minerals. In the diaphragm type jig, the reciprocating movement of the diaphragm generates pulsating water flow, so that mineral particles are layered according to density: large particles and high-density materials sink to the bottom, while light particles float on the upper layer.

[0003] A Chinese invention patent with the authorized announcement number CN112317119B discloses an independent air chamber jig, which comprises a compressed air source, a wind box and a jigging chamber with a screening groove at the top. The wind box is provided with an air inlet end, an air outlet end and an air supply end. An air inlet valve is arranged on the air inlet end, and an air outlet valve is arranged on the air outlet end. The compressed air source is connected to the air inlet end through an air pipe. A ventilation pipeline is arranged in the jigging chamber, one end of the ventilation pipeline is blocked, the other end of the ventilation pipeline extends out of the jigging chamber and is connected to the air supply end through an air pipe. A plurality of independent air chambers are uniformly distributed in the jigging chamber. The top of each independent air chamber is closed, the bottom of each independent air chamber is open, a deformation diaphragm is arranged in each independent air chamber to separate the independent air chamber into an inner air chamber and an outer air chamber, and each inner air chamber is connected in parallel with the ventilation pipeline. The above scheme realizes air and water contact-free, avoids the influence of water carried out by exhaust gas on the valve action, improves the reliability of the equipment, avoids the phenomenon of water running, solves the problem of uneven transverse pulsating water flow after the large-scale of the equipment, and relies on the delivery of multiple air sources for multiple independent air chambers. The intensity of jigging vibration depends on the pressure control of the air source. When it is necessary to increase or reduce the intensity of jigging vibration, the pressure adjustment of the air source often has a certain hysteresis, which cannot meet the demand in time. Since multiple air chambers work independently, the pressure distribution between the air chambers may be uneven, which further affects the uniformity and stability of the jigging vibration. Therefore, the air source has poor adjustability when driving large water flow, and there is room for improvement. SUMMARY
