Problems solved by technology

The disadvantage of this method is that the scope of the overhaul process is too large, interrupting the continuity of production and reducing economic benefits
This structure still has the following disadvantages: the scope of influence of the maintenance process is relatively large, which reduces the output and economic benefits
The former has huge impact and loss, while the latter has a large number of equipment, and the workload of management and maintenance is very heavy

Embodiment Construction

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] see figure 1 and 2 , The shielding device for the pulp outlet of the mineral processing system includes a joystick 10 with a large dead weight, and the joystick is a steel joystick.

[0023] The lower end of the joystick 10 is provided with a plugging piece for blocking the pulp outlet, and the plugging piece includes a conical rubber plug 21 with a large upper part and a smaller lower part. The conical rubber plug is clamped by upper and lower gaskets (22, 23). Gaskets (22, 23) are steel gaskets. Joystick runs through upper gasket 22, rubber plug 21, lower gasket 23, and the end of lower gasket 23 is tightened by a pair of locknuts (not marked in the figure), keeps certain pretightening force, prevents from coming off. A 10x10mm ch...

Abstract

The invention discloses a shielding device for an ore pulp outlet of a mineral separation system. The shielding device comprises a control rod with high self-weight. A blocking piece used for blocking the ore pulp outlet is arranged at the lower end of the control rod and comprises a big-end-up truncated-cone-type rubber plug. The truncated-cone-type rubber plug is clamped by an upper gasket and a lower gasket. The control rod penetrates the upper gasket, the rubber plug and the lower gasket. The tail end of the lower gasket is screwed down by a pair of anti-loosening nuts. When being used, the shielding device is manually taken down by operators, the specified ore pulp outlet is plugged by the blocking piece at the lower end, and when the ore pulp outlet is plugged, the posture of the shielding device is adjusted, and the control rod is perpendicular to the bottom plane of an ore distribution cylinder bottom. As the self-weight of the control rod is high, the rubber plug can be well attached to the upper edge of the ore pulp outlet, so that ore pulp is blocked, and overhauling of downstream equipment is facilitated.

Description

technical field [0001] The invention relates to the field of mineral processing equipment, in particular to a shielding device for the pulp outlet of the mineral processing system, which can be used in the mineral processing system of an integrated ship for mining and mineral processing, an offshore mineral processing platform or a mineral processing ship, or a mineral processing system of a land mineral processing project. Background technique [0002] Some small-scale mineral processing systems only have 20 to 30 spiral chutes. Once a major fault occurs and needs to be overhauled, the entire mineral processing system can only be stopped. The disadvantage of this method is that the scope of the overhaul process is too large, which interrupts the continuity of production and reduces economic benefits. In order to reduce the failure rate and reduce the number of inspections, it is necessary to arrange a long-term inspection before starting the operation or after stopping the ...
