Description

A kind of diagrid

Technical field

The utility model relates to ore reduction field, is specifically related to a kind of diagrid.

Background technology

In ore processing field; first operation is mostly ore reduction; general Ge great disintegrating machine manufacturer is when disintegrating machine designs; the Utopian ore source considered; do not consider the inhomogeneities of ore explosion, the ore exceeding disintegrating machine process maximum particle size occasionally occurs, after entering disintegrating machine; very easily cause disintegrating machine to increase instantaneously because of electric current, exceed overcurrent protection threshold value and shut down.But, due to the ore that broken feed bin is piled up after your shutdown of disintegrating machine, for most disintegrating machine, directly restart out of the question often, this adds increased the time of process this kind of problem, greatly reduce production efficiency, likely damage disintegrating machine especially.In order to stop the variety of problems that lump ore brings, we need a kind of can by this minute quantity but once occur bring the lump ore of significant damage to filter again the device of secondary blasting.

Utility model content

The purpose of this utility model is to provide a kind of diagrid, and the super lump ore occurred because explosion is uneven was separated secondary blasting again before entering disintegrating machine, reduces disintegrating machine card and stops, enhance productivity, extend the disintegrating machine life-span.

For realizing the purpose of this utility model, the technical scheme adopted is: a kind of diagrid, it is characterized in that, comprise sieve nest muscle, gusset plate, described sieve nest muscle comprises horizontal bar and longitudinal rib, described horizontal bar and longitudinal rib mutually vertically arrange and be fixedly connected with, longitudinally muscle direction by charge level, gusset plate is set, described gusset plate is fixedly connected with sieve nest muscle.

Further, the connected mode between described horizontal bar and longitudinal rib is bayonet coupling and reinforcement of weld.

Further, the width of described gusset plate is greater than the thickness of sieve nest muscle.

Further, described sieve nest muscle adopts low-carbon (LC) steel to make.

The beneficial effects of the utility model:

The purpose of this utility model is to provide a kind of diagrid, be arranged on the broken feed bin of disintegrating machine, when loading machine or truck material loading, ore is first through diagrid, and the ore meeting disintegrating machine maximum process granularity can enter broken feed bin smoothly, and the super lump ore occurred because explosion is uneven then can not enter above diagrid, take measures in time to be separated secondary blasting again, reduce disintegrating machine card to stop, enhance productivity, extend the disintegrating machine life-span.The utility model adopts the thick low carbon steel plate of 40mm, and sieve nest bayonet type is installed and also formed by reinforcement of weld, compares the high-carbon steel such as rail steel, has more excellent toughness, intensity and impact resistance have one preferably comprehensive; The gusset plate by charge level employing strip of diagrid is reinforced; bayonet socket junction can be protected, make bayonet socket junction not fragile, be more cleverly; adopt this width to be greater than the gusset plate of sieve nest muscle thickness, make sieve aperture to be blocked by lump ore and to increase intractability.

Accompanying drawing explanation

Fig. 1 is a kind of diagrid upward view that the utility model provides;

Fig. 2 is bayonet socket syndeton schematic diagram.

Detailed description of the invention

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

Fig. 1 shows a kind of diagrid that the utility model provides, and comprises longitudinal sieve nest muscle 1, horizontal sieve nest muscle 2, gusset plate 3, and longitudinal sieve nest muscle 1 and horizontal sieve nest muscle 2 are connected by bayonet socket 4 is mutually vertical, is fixedly installed gusset plate 3 at longitudinal sieve nest muscle 1 by charge level.Good combination property is had in order to make the toughness of sieve nest entirety, resistance to impact, intensity, as preferably, longitudinal sieve nest muscle 1, horizontal sieve nest muscle 2 and gusset plate 3 all adopt low-carbon (LC) steel, diagrid is not easily frequently ruptured under huge ore impacts, alleviates maintenance load; Gusset plate 3 be arranged on longitudinal sieve nest muscle 1 by charge level, one makes bayonet socket position avoid directly being subject to ore impacts, life-span is extended, two, the width of gusset plate 3 is greater than the thickness of longitudinal sieve nest muscle 1, obviously make the shape of sieve aperture be up-small and down-big, avoid the ore suitable with sieve diameter and be stuck in sieve aperture, convenient process.

Fig. 2 shows the schematic diagram that bayonet socket connects 4, and as preferably, the bayonet socket degree of depth on longitudinal sieve nest muscle 1 and horizontal sieve nest muscle 2 is 1/2nd of respective width respectively, the even intensity of whole sieve nest is distributed, is conducive to increasing the service life; Connect 4 places at bayonet socket, reinforcement of weld, make sieve nest have good rigidity to resist elastic deformation.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
