Description
Technical Field
The utility model relates to a protection device for a receiving surface of an inner wall of a head hopper of a coal conveying system.
Background
The belt conveyor (for short, the belt conveyor) has the advantages of large conveying capacity, small power consumption, high efficiency, strong adaptability to materials and the like, so that the belt conveyor is widely applied to the fields of coal mines, steel plants, power plants and the like.
In a coal conveying system of a thermal power plant, a head hopper is one of important equipment, and has the function of collecting and turning coal conveyed by a coal conveying belt, and conveying the coal to the next coal conveying belt after passing through a coal dropping pipe. The head hopper is generally of the open type, and also of the closed type. The coal is washed by the coal conveying belt for a long time, the position of the material receiving surface on the inner wall of the head hopper is extremely easy to damage and wear thoroughly, and although the head hopper of the coal conveying system is modified into a lining plate type or a wall plate is directly manufactured by a build-up welding lining plate in the prior thermal power plant of a large department, the wear resistance of the wall plate is only increased, the essence of hard washing of the wall plate by the coal is not changed, and moreover, the wear-resistant lining plate is expensive in cost and is very troublesome to replace. When the novel lining plate is replaced, the belt operation is stopped, the damaged lining plate is cut off by oxygen or plasma, and the novel lining plate is fixedly fixed by bolts or welding after being replaced, so that the novel lining plate is time-consuming, labor-consuming and fund-consuming in work, and potential safety hazards such as fire, object striking, burns, scalds, crush injury, falling and the like are also present in the replacement process.
Disclosure of Invention
The utility model aims to provide a protection device for the receiving surface of the inner wall of a head hopper of a coal conveying system.
The above object is achieved by the following technical scheme:
the utility model provides a coal conveying system head funnel inner wall receiving face protection device which constitutes and includes: the coal conveying belt is arranged on one side of the head funnel, the bottom of the head funnel is connected with the coal dropping pipe, the material receiving surface protection device is arranged on the inner inclined wall of the head funnel and consists of an alloy grid plate and a hook, the hook is fixedly connected with the alloy grid plate, the grid plate consists of a group of small grids which are uniformly arranged, and the small grids are of square structures.
The coal conveying system head hopper inner wall receiving surface protection device is characterized in that one end of a hook is connected with the top of a grid plate, and the other end of the hook is connected with the inner wall of the head hopper.
The coal conveying system head hopper inner wall receiving surface protection device is characterized in that the hooks are of steel bars or flat steel structures.
The device for protecting the receiving surface of the inner wall of the head hopper of the coal conveying system is characterized in that the size of each small grid on the grid plate is 100mm x 50mm, and the size of each small grid is 100mm x 50mm.
The utility model has the beneficial effects that:
1. the utility model has reasonable design, simple structure, quick replacement, strong practicability and low production cost, and can effectively avoid the hidden trouble of equipment which is worn by scouring the inner wall of the receiving surface of the head funnel, thereby saving the overhaul operation cost of enterprises.
2. The head funnel inner wall receiving surface protection device is simple in structure, quick to replace and high in practicability, is low in production cost, and can effectively avoid equipment hidden trouble caused by abrasion due to scouring of the head funnel inner wall receiving surface, so that the overhaul operation cost of enterprises is saved.
3. The alloy grid plate is made of wear-resistant alloy and paved on the receiving surface of the inner wall of the head funnel, the overall size of the grid plate is matched with the size of the receiving surface of the head funnel, the grid plate consists of a plurality of small grids which are uniformly arranged, the small grids are of square structures, and the sizes of length, width and thickness are 100mm, 100mm and 50mm; the grid plate hook is made of steel bars or flat steel, one end of the grid plate hook is welded at the top of the grid plate, and the other end of the grid plate hook can be firmly hung on the inner side wall of the head funnel.
4. The utility model has the following advantages:
(1) Reasonable design and extremely simple and convenient manufacture. According to the field size, welding the wear-resistant alloy plates into a grid shape;
(2) The installation is convenient and the replacement is quick. When the protective device is installed and replaced, the protective device is only required to be lifted out of the funnel, and a new protective device is put in and hung;
(3) Long service life, economy and practicality. The working principle of the protection device is that coal and coal impact, only the vertical face of the grid plate is washed, and the grid plate is made of wear-resistant alloy, so that the protection device can be used for a long time;
(4) The labor intensity can be reduced to the greatest extent, and the labor investment is reduced. The original replacement of a funnel lining plate or a surfacing wall plate is completed by 3 persons and 6 hours, the protection device is replaced now, and the labor is completed by 2 persons and 1 hour;
(5) The potential safety hazard is reduced. In the replacement process of the protection device, the potential safety hazards of fire, object striking, burns, scalds, squeezing injuries, falling and the like can be effectively avoided;
(6) The utility model has wide application range, easy popularization and implementation and obvious economic benefit. When the coal conveying belt runs, part of coal falls into the grid of the protection device, after the grid is filled with the coal, the falling coal impacts the coal in the grid, and then potential energy is discharged, the direction is changed, and the falling coal falls into the coal dropping pipe. The impact between coal and coal is formed instead of flushing the receiving surface of the inner wall of the hopper, so that the damage to the wall plate is avoided.
