Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical roasting equipment, in particular to a sample placing rack for roasting pellet ore in a furnace. Background Art

[0002] The sample placing rack is applied to roasting pellet ore in a high-temperature furnace in a laboratory. The existing sample placing rack for pellet ore in a furnace is generally a single-layer trough-shaped with gas circulation pores at the bottom. The sample placing rack is heavy and inconvenient to take from the furnace chamber, with a single function. Moreover, under specific atmosphere conditions, the gas does not contact the pellet ore sample sufficiently. In addition, the ordinary single-layer sample placing rack cannot conveniently and effectively roast different groups of test samples in a single experiment, and the thickness of the placed pellet ore samples cannot be too high, otherwise, during the heating process, the pellet ore will be unevenly heated and affected by the atmosphere, which will affect the experimental results. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sample placing rack for roasting pellet ore in a furnace, so that the pellet ore is more evenly affected by gas, has multiple functions, and can roast different groups of test samples simultaneously.

[0004] The purpose of the utility model can be realized by the following technical solutions:

[0005] A sample placing rack for roasting pellet ore in a furnace, the sample placing rack includes a bearing plate, and a plurality of Y-shaped through grooves are formed in the bearing plate, and a raised structure is arranged between adjacent Y-shaped through grooves.

[0006] In a further solution, the bottom surface of the bearing plate is flat.

[0007] In a further solution, support walls are arranged at both ends of the bearing plate, the bearing plate is located below the support walls, a plurality of ventilation openings are arranged in the middle of the support walls, and the distance between the bottom surface of the support walls and the bottom surface of the bearing plate allows a forklift to pass through.

[0008] In a further solution, baffles are arranged on both sides of the sample placing rack, and the baffles are arranged between the two support walls.

[0009] In a further solution, a gap for ventilation is arranged between the baffle and the upper surface of the bearing plate, and the size of the gap is not enough for the pellet ore to pass through.

[0010] In a further solution, assembly grooves that can cooperate with each other are arranged at the upper and lower ends of the support walls, and the assembly grooves are used to prevent the sample placing racks from sliding to one end when two sample placing racks are stacked.

[0011] In a further solution, the raised structure is in the shape of a frustum of a pyramid.

[0012] In a further solution, the cross section of the raised structure is an isosceles trapezoid.

[0013] In a further embodiment, the length of the bottom opening of the Y-shaped through groove is not sufficient for the furnace pellets to fall out therefrom.

[0014] In a further embodiment, the length of the upper opening of the Y-shaped through groove is less than the average diameter of the furnace pellets.

[0015] Advantages of the present utility model:

[0016] By means of the Y-shaped through groove and the raised structure, the present utility model can provide a surface on the upper surface of the sample placement rack that is more conducive to the stable placement of the furnace pellets without sliding. The furnace pellets can be stacked in the Y-shaped through groove and the raised structure, allowing more furnace pellets to be placed at one time, and increasing the ventilation volume of the bottom furnace pellets, thereby making the overall air intake more sufficient, the air intake range wider, and more uniform.

[0017] Inverting the above-mentioned sample placement rack through the flat bottom surface can facilitate the placement of samples such as crucibles used in the roasting process, improving its functionality.

[0018] Designing an installation groove structure that facilitates the stacking of the sample placement racks allows different groups of test samples to be placed on the sample placement racks in different up-and-down directions for simultaneous experiments.

[0019] The entire sample placement rack can be ventilated from all four sides, improving the uniformity of heat reception. Description of the drawings

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 shown, a sample placing rack for roasting pellet ore of a furnace includes a bearing plate 1. A plurality of Y-shaped through grooves 101 are formed in the bearing plate 1, and a raised structure 102 is arranged between adjacent Y-shaped through grooves 101. Through the Y-shaped through grooves 101 and the raised structure, a surface that is more conducive to the stable placement of the pellet ore of the furnace without sliding can be provided on the upper surface of the sample placing rack. The pellet ore of the furnace is stacked in the Y-shaped through grooves 101 and the raised structure, and more pellet ore of the furnace can be placed at one time, and the ventilation volume of the pellet ore at the bottom can be increased, so that the overall air intake is more sufficient, the air intake range is wider, and it is more uniform.

[0026] As Figure 2 shown, the bottom surface of the bearing plate 1 is flat. The flat surface can be used to place samples such as crucibles used in the roasting process when inverted.

[0027] As Figure 1 shown, support walls 2 are arranged at both ends of the bearing plate 1. The bearing plate 1 is located below the support walls 2. A plurality of ventilation openings 201 are arranged in the middle of the support walls 2. The distance h between the bottom surface of the support walls 2 and the bottom surface of the bearing plate 1 allows a forklift fork to pass through. This facilitates the handling of the sample placing rack by the forklift fork and specific tools, and solves the problem that it is inconvenient to pick up the heavy sample placing rack.

[0028] Baffles 3 are arranged on both sides of the sample placing rack, and the baffles 3 are arranged between the two support walls 2. This can prevent the pellets from falling from the side and improve the strength between the support walls 2.

[0029] A gap d for ventilation is arranged between the baffle 3 and the upper surface of the bearing plate 1, and the size of the gap d is not enough for the pellet ore of the furnace to pass through. This not only facilitates side ventilation but also prevents the pellets from falling.

[0030] Fitting grooves 202 that can cooperate with each other are arranged at the upper and lower ends of the support walls 2, and the fitting grooves 202 are used to prevent sliding to one end when two sample placing racks are stacked. It is convenient to limit the position of the stacked sample placing racks.

[0031] The raised structure 102 is in the shape of a frustum of a pyramid. The frustum-shaped surface can be used to carry the pellets, and the edges can separate adjacent pellets.

[0032] The cross-section of the raised structure 102 is an isosceles trapezoid. In this way, the force at each Y-shaped through groove 101 is more uniform and the ventilation is more uniform.

[0033] The bottom opening length of the Y-shaped through groove 101 is not sufficient for the furnace pellet ore to fall out therefrom. This can prevent the furnace pellet ore from falling during roasting.

[0034] The upper opening length of the Y-shaped through groove 101 is smaller than the average diameter of the furnace pellet ore. This can accommodate as many furnace pellet ores of the existing size as possible and prevent the furnace pellet ore from blocking the Y-shaped through groove 101, resulting in insufficient ventilation.

[0035] In actual use, the overall dimensions of the sample placement rack can be made 250*160*100 mm. The furnace pellet ore is placed in the Y-shaped through groove 101 and stacked along both sides of the Y-shaped through groove 101. The sample placement rack filled with furnace pellet ore is placed in a high-temperature furnace and roasted through the air in three layers.
