Arc-shaped grid bar valve device of chute

Abstract

The invention relates to an arc-shaped grid bar valve device of a chute. The arc-shaped grid bar valve device comprises the chute. The arc-shaped grid bar valve device is characterized in that the arc-shaped grid bar valve device is arranged at the lower part of the chute, an arc-shaped claw drill rod passage is formed, the device comprises an arc-shaped grid bar valve and a hydraulic system, thearc-shaped grid bar valve includes an arc-shaped claw drill rod, a transverse beam and two triangular swing arms, the arc-shaped claw drill rod is fixedly connected to the transverse beam, two shaft sleeves at the upper ends of the two triangular swing arms are rotationally connected with lug shafts on front and rear side plates of the chute, and the lower ends of the two triangular swing arms arein bolted connection to the two ends of the transverse beam; and the hydraulic system includes a hydraulic station, two hydraulic oil cylinders and a fixed bracket, the two hydraulic oil cylinders are hinged to the fixed bracket, and telescopic rods of the two hydraulic oil cylinders are hinged to the lower ends of the two triangular swing arms. The arc-shaped grid bar valve device has the advantages that a switch of the valve is hydraulically driven, the efficiency is high, time and labor are saved, the structure is simple, space is saved, installation is facilitated, and operation is quick.

Description

technical field [0001] The invention belongs to the technical field of valves used for flow control of a chute, in particular to an arc-shaped grid rod valve device for a chute. Background technique [0002] In metallurgy, mining and other industries, chutes are often used to divert or transfer bulk materials, and sometimes it is necessary to cut off or control the flow of bulk materials. Therefore, it is necessary to install a valve device in the middle of the chute. At present, in the practical application of production, the widely used valve device is the flat gate. The problem existing in the use of the flat gate is that the resistance to be overcome when the flat gate is closed is very large, and sometimes it cannot be closed due to blockage of block materials. In order to overcome this deficiency, combined with the characteristics of bulk materials, rod valves will be used instead of flat gates in production. The rod valve has the advantages of simple structure, small...

Problems solved by technology

At present, in the practical application of production, the widely used valve device is the flat gate. The problem existing in the use of the flat gate is that the resistance to be overcome when the flat gate is closed is very large, and sometimes it cannot be closed due to blockage of block materials.

However, the rod valve needs to be manually operated. It is time-consuming and labor-intensive to knock the rods into the chute one by one or pull them out from the chute, and the material cannot be cut off and flow controlled in time, which affects production.
