Abstract
The utility model belongs to the mining machinery field discloses a novel raw ore bin lattice screen. The raw ore bin lattice sieve comprises a lattice sieve frame and a protective funnel, wherein the lattice sieve frame is formed by welding H-shaped steel and a steel plate; the protective funnel is arranged in each grid frame hole, so that a new grid structure is formed; the protective funnel is processed by adopting an integral casting process; the two right side inner walls of the protection funnel are provided with semicircular hoisting holes, so that the protection funnel can be conveniently hoisted by using a steel wire rope or other hoists. The utility model discloses installing protection funnel in the lattice sieve frame, playing the guard action to the lattice sieve frame, extension lattice sieve life reduces down time and maintenance work load, reduces the lattice sieve maintenance cost.
Description
Technical Field
The utility model belongs to the mining machinery field relates to a novel raw ore storehouse check sieve, mainly is applied to the raw ore storehouse upper portion in the ore crushing stage for the bold ore that the screening surpasss the granularity scope.
Background
The existing raw ore bin frame is formed by assembling and welding H-shaped steel with the size of 140 x 406mm, Q235 steel plates with the thickness of 10mm are welded with the H-shaped steel around a frame hole, a guard plate is welded above the frame, and the guard plate is a whole Q345B steel plate with the thickness of 40mm and the opening size of which is slightly smaller than that of the grid screen frame hole. In the production, use mining truck to fall down the ore on check sieve frame, be less than the ore of sieve mesh size and fall into the ore deposit storehouse, be greater than the ore deposit storehouse of sieve mesh size in can't fall into the ore deposit storehouse, hit with the help of the hydraulic pressure quartering hammer and hit and beat into the rubble and fall into the ore deposit storehouse after. The raw ore of the whole vehicle is poured onto the lattice screen frame, and then the lattice screen frame is impacted to a great extent by the impact of the breaking hammer, and the guard plate above the frame and the steel plates around the H-shaped steel are frequently broken, welded and deformed. Under the current technical condition, the service life of the raw ore bin screen is short, the maintenance amount is large, the cutting amount and the welding amount are extremely large during maintenance, the maintenance workload and the maintenance cost are increased, and meanwhile, the continuity of production is influenced.
SUMMERY OF THE UTILITY MODEL
In view of above-mentioned technical problem, the utility model provides a novel former ore bin grizzly installs the protection funnel of the high manganese steel casting structure of design in the grizzly frame, plays the guard action to the grizzly frame, extension grizzly life reduces down time and maintenance work load, reduces grizzly maintenance cost.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts as follows:
a novel raw ore bin grid screen comprises a grid screen frame and a protective funnel. The lattice frame is formed by assembling and welding H-shaped steel and steel plates; the protective funnel is processed by adopting an integral casting process, is made of ZGMn13Cr2 material, has strong impact resistance and wear resistance, and is widely applied to the crushing and grinding fields of toothed plates of crushers, lining plates of ball mills and the like; meanwhile, semicircular hoisting holes are designed in the inner walls of the two sides, which are just opposite to the protection funnel, so that the protection funnel can be conveniently hoisted by using a steel wire rope or other hoists when being replaced. The protection funnel install in every check sieve frame hole to form a new check sieve structure, this novel check sieve shock resistance, wearability are strong, frame construction is stable, difficult wearing and tearing, newly-designed check sieve life prolongs greatly, and overhauls conveniently save time, has guaranteed the equipment rate of perfectness.
Effect of the utility model
Newly-designed former ore bin lattice sieve life prolongs greatly, prolongs the maintenance cycle of three months to two years, and newly-designed lattice sieve overhauls conveniently, if appear wearing and tearing only need change protection funnel can, overhaul safety, swift, improved equipment availability factor, reduced the daily maintenance cost, guaranteed the continuity of production.

fig. 2 is a three-dimensional schematic view of the protection funnel of the present invention;
in the figure: 1-protective funnel, 2-grizzly frame, 3-H shaped steel, 4-steel plate.
Detailed Description
Referring to fig. 1 and 2, the novel raw ore bin grid screen provided by the utility model comprises a grid screen frame and a protective funnel, wherein the grid screen frame 2 is formed by welding H-shaped steel 3 and steel plates 4; protection funnel 1 install in every check sieve frame hole to form a new check sieve structure, protection funnel plays the guard action to check sieve frame, prolongs the life of check sieve frame. The protective funnel is processed by adopting an integral casting process, is made of ZGMn13Cr2 material, has strong impact resistance and wear resistance, and is widely applied to the crushing and grinding fields of toothed plates of crushers, lining plates of ball mills and the like; meanwhile, semicircular hoisting holes are designed in the inner walls of the two sides, which are just opposite to the protection funnel, so that the protection funnel can be conveniently hoisted by using a steel wire rope or other hoists when being replaced.
The simple and easy stock limited company of the kemi ka mining industry can use 3 months after laying the whole 40mm thick backplate behind the former ore bin lattice screen frame of ore dressing plant, and the later stage all needs to weld repair monthly, and the maintenance volume is big and overhaul frequently, causes certain restriction to production continuity. Adopt the utility model provides a novel former ore bin lattice screen to installed and used ZGMn13Cr2 cast lattice screen protection funnel, used more than one year, no any maintenance volume, expected life can reach two years, excellent in use effect. The service life of the newly designed grid sieve is greatly prolonged, the daily maintenance is reduced, the production cost is reduced, and the production continuity is ensured.
