Installation of new structure for air-gun combined dredging machine

Abstract

The invention discloses an installation of a new structure of an air-gun combined dredging machine, comprising a conical stock bin with larger upper part and smaller lower part, an air gun is arranged outside the stock bin, the air nozzle of the air gun is obliquely arranged downwards in the stock bin, the inner wall of the stock bin is provided with a dredger and a hydraulic cylinder which is arranged above the dredger, and the piston of the hydraulic cylinder and the top end of the dredger are connected in a driving mode; the air gun and the dredger are installed in the same stock bin and share one control cabinet; when the stock bin is blocked, a feed breaking signal displays, the air gun begins to work, and the dredger begins to carry out cyclic motion up and down after one second, until the feed breaking signal disappears; thus, the optimum blockage cleaning and dredging effect is performed on blocking phenomenon, such as materials jamming, bin wall bonding, bridging and the like; the effect of the invention is multiplied many times over that of single operation for the air gun or the dredging machine, and the invention is especially suitable for the dredging operation for blockage of damp or easily-bonding materials.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a new installation structure of an air cannon combined dredge machine. Background technique [0002] Both the air cannon and the dredger are special devices for preventing and eliminating material arching, silo blockage, wall sticking, and retention at various types of silos, hoppers, and pipeline bifurcations. They are widely used in electric power, coal, chemical, Metallurgy, building materials and other important occasions for storage and transportation of bulk materials. The silos containing materials are generally square cones and cones with a large top and a small bottom. The air cannon is especially effective for dredging the blockage of materials with little moisture and relatively dry materials. If it encounters wet and easily sticky materials, it can be cleared The role of dredger is not great, dredge machine is not only suitable for clearing dry m...

AI Technical Summary

Problems solved by technology

At present, many domestic manufacturers of electric power, coal, chemical industry, metallurgy, building materials, etc. have only installed one type of air cannon and dredge machine in their silos, especially the silos with only air cannons installed, many materials have relatively high moisture content Or viscous, the problem of material clogging the silo often occurs, and the effect of unclogging and dredging is not good, which seriously affects the normal and continuous production operations

In addition, there is a deformation angle on the gate of many silos, and the dredger can only be installed at a higher distance from the gate, so that the dredge cannot be pushed down properly, causing material blockage at the gate

[0003] The existing dredging machine includes a dredging device installed in the silo, and the existing dredging device has the following disadvantages. The dredging device includes a vertically arranged pull rod, and several scrapers are arranged on the pull rod, and a limit card is arranged outside the pull rod The ring and clasp are welded to the pre-set embedded parts on the inner wall of the silo. When the tie rod moves up and down, the whole tie rod directly rubs against the wall of the silo, and the friction is very large, which increases the wear of the tie rod; the existing tie rod adopts Channel steel has limited bending resistance and is not very durable; and because the transverse lengths of all scrapers are equal, the hydraulic power is large when starting, and it is not easy to start, and when the scrapers move downward, the resistance is very large, and the load on the hydraulic device is relatively large , power consumption also increases, virtually reducing the service life of hydraulic cylinders, oil pumps, electromagnetic reversing valves, motors, electronic components and other components
