Generally, a large-scale pellet mill is provided with a plurality of ore bins, three ore bins form a group, each ore bin is provided with a single grate, the existing protective grate is circular, the diameter of the grate is larger than that of the top of the ore bin, the grate is arranged at the top of the ore bin, and a certain gap is reserved between the edge of the grate and the ground and a retaining wall around the ore bin. The material loading operation in iron ore concentrate powder storehouse is accomplished by bridge type grab bucket machine, the straight line distance of grab bucket machine operation panel distance ore bin top is 30 meters, so distance, including the site environment dust is big, light is not enough, only rely on operating personnel's eyes to judge, there is great error, cause the grab bucket machine often to scrape, hit the edge of ore bin top protection grate, and the grab bucket machine still frequently strikes the barricade in the ore bin outside, this kind is scraped, hit and causes very big destruction to protection grate and barricade, it is serious to cause protection grate and the barricade at ore bin top to damage, there is great potential safety hazard.
The invention content is as follows:
the utility model discloses a solve the problem that above-mentioned exists, provide a protector suitable for ore bin top, this protector can reduce the grab bucket machine to the scraping and striking at protection grate edge to can avoid the barricade by direct striking, reduce the repair time of ore bin protection grate and barricade, realize cost reduction and efficiency improvement.
The utility model discloses a realize through following technical scheme:
the utility model discloses a mining storehouse top protector, including mining storehouse, spandrel girder, barricade and protection grate, its characterized in that: the ore bin is the three ore bin of vertical sitting in ground, establishes between 2 adjacent vertical spandrel girders, the barricade is transversely established in the feeding side in three ore bin be equipped with L shape barricade guard plate on the barricade, the protection grate is the rectangle structure, establishes at three ore bin top, protection grate and L shape barricade guard plate fixed connection.
Preferably, the ore bin protection grate is formed by embedding and fixedly connecting mutually parallel transverse thick iron plate strips and mutually parallel vertical thin iron plate strips, wherein the thick iron plate strips are 30mm thick, 100mm wide and 6m long, and the thin iron plate strips are 20mm thick, 150mm wide and 6m long.
Preferably, the ore bin protection grate is vertically provided with 70mm deep grooves at intervals of 400mm in the length direction of the thin iron plate strips, the thick iron plate strips are vertically inserted into the deep grooves of the thin iron plate strips and welded together, and the thick iron plate strips are arranged higher than the thin iron plate strips.
Preferably, the L-shaped protection plate hangs down for 2 meters along the retaining wall.
The utility model has the advantages that:
because the utility model discloses having changed into holistic rectangle structure with a plurality of ore storehouse protection combs, and set up the L shape barricade guard plate that is connected with rectangle protection comb on the barricade, not only filtered debris and the bold in the material effectively, but also played the effect of buffering material falling speed, reduced grab bucket machine to the scraping and striking at protection comb edge to can avoid the barricade to be strikeed by direct, reduce the repair time of ore storehouse protection comb and barricade, realize cost reduction and efficiency improvement.
Drawings
Fig. 1 is a top view of the present invention.
Fig. 2 is a left side view of fig. 1.
Fig. 3 is a schematic view of a rectangular protective grate on the top of the ore bin.
In the figure, 1, a retaining wall, 2, an ore bin, 3, a bearing beam, 4, an L-shaped protective iron plate, 5, a rectangular protective grate, 6, a thick iron plate strip, 7 and a thin iron plate strip are arranged.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, a top protection device for an ore bin comprises an ore bin 2, a bearing beam 3, a retaining wall 1 and a protection grate 5, and is characterized in that: ore bin 2 is the three ore bin of vertical sitting in ground, establishes between 2 adjacent vertical spandrel girder 3, barricade 1 transversely establishes in the feed side of three ore bin 2 be equipped with L shape barricade guard plate 4 on the barricade 1, protection grate 5 is the rectangle structure, establishes at three ore bin top, protection grate 5 and L shape barricade guard plate 4 fixed connection. The protective grate 5 and the L-shaped retaining wall protective plate 4 can be welded or in threaded connection, for example, the protective grate and the L-shaped retaining wall protective plate are connected through bolts, and when parts are damaged, the protective grate and the L-shaped retaining wall protective plate are convenient to disassemble and repair. Because the utility model discloses having changed into holistic rectangle structure with a plurality of ore bins protection combs, and having set up the L shape barricade guard plate that is connected with rectangle protection comb on the barricade, not only filtered debris and the bold in the material effectively, but also played the effect of buffering material falling speed, reduced the scratch and the striking of grab bucket machine to protection comb edge.
Ore bin protection grate 5 inlays the rigid coupling mutually by horizontal thick iron plate strip 6 that is parallel to each other and vertical thin iron plate strip 7 that is parallel to each other and forms, and thick iron plate strip 6 size is 30mm thick, 100mm is wide and 6m is long, and thin iron plate strip 7 size is 20mm thick, 150mm is wide and 6m is long.
The ore bin protection grate 5 is characterized in that a 70mm deep groove is vertically formed in the length direction of each thin iron plate strip 7 at intervals of 400mm, thick iron plate strips 6 are vertically inserted into the deep grooves of the thin iron plate strips 7 and welded together, and the thick iron plate strips 6 are higher than the thin iron plate strips 7. The L-shaped protection plate 4 is hung 2 meters along the retaining wall. The design is to only enable the thick iron plate strips 6 to be in contact with the grab bucket, the thin iron plate strips 7 are not in contact with the grab bucket, and the opening and closing directions of the thick iron plate strips 6 and the grab bucket are consistent, so that the possibility of scraping and colliding the protective grate by the grab bucket is reduced.
When the protective grate and the L-shaped iron plate are preferably connected through bolts, the protective grate is convenient to disassemble and repair when part of the protective grate is damaged.
