Abstract
The utility model provides a sintering machine platform truck grid section, it is including the main part, and the outside below of main part bottom both sides direction extends and forms the base arm, and the main part both ends are the contact arm, and two relative one sides of base arm form "eight" font, and the outside level extension in base arm bottom forms and strengthens the seat, and the contact arm bottom is the arc, and its extrados is downward. Ventilation area grow behind this scheme of adoption, the radiating effect is good.
Description
Technical Field
The utility model belongs to the technical field of sintering machine platform truck technique and specifically relates to indicate a sintering machine platform truck grid section.
Background
Because the grate bars of the original sintering machine trolley are in surface contact with the heat insulation sleeve, most of heat of the grate bars is transferred to the heat insulation sleeve, so that the temperature of the heat insulation sleeve is high, and the temperature of the trolley body is also high. The heat radiation condition of the heat insulation sleeve is not good, so that the heat insulation part is relatively consumed, and the trolleys cracked due to high temperature are relatively more. And the grate bar is also consumed greatly due to poor heat dissipation. Because the heat insulation sleeve and the grate bar are consumed greatly and need to be replaced frequently, the normal operation of production and equipment is influenced, and the quality and the yield of the sinter are also influenced.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide a sintering machine platform truck grid section that draught area grow, radiating effect are good.
In order to achieve the above object, the present invention provides a technical solution: the utility model provides a sintering machine platform truck grid section, it includes the main part, and main part bottom both sides outside below extends and forms the base arm, and the main part both ends are the contact arm, and two opposite sides of base arm form "eight" font, and the base arm bottom outwards extends horizontally and forms the reinforcing seat, and the contact arm bottom is the arc, and its outer cambered surface is downwards.
The contact arm and the base arm are in arc smooth transition.
The vertical section of the main body is in a trapezoid shape with a large upper part and a small lower part, the section of the contact arm is in a square shape, and a stepped limiting step is formed between the contact arm and the main body.
The upper part of the contact arm protruding out of the main body is provided with an inclined transition surface, and the lower end of the transition surface is positioned on one side of the main body.
By adopting the above technical scheme, the contact surface between contact arm and the outside radiation shield changes into the arcwall face by original plane, and therefore, contact arm is line contact with the contact of outside radiation shield, changes the grid section heat radiating area grow behind the line contact into, and the draught area grow, the radiating effect is good.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic diagram of the structure of the limiting step of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to fig. 1 and 2, the sintering machine trolley grate bar according to the embodiment includes a main body 1, two sides of the bottom of the main body 1 extend outwards and downwards to form base arms 2, two ends of the main body 1 are contact arms 4, opposite sides of the two base arms 2 form a shape like a Chinese character 'ba', the bottom of each base arm 2 extends outwards and horizontally to form a reinforcing seat 3, the bottom of each contact arm 4 is arc-shaped, the outer arc surface of each contact arm faces downwards, the contact arms 4 and the base arms 2 are in smooth arc transition, the vertical section of the main body 1 is trapezoid with a large top and a small bottom, the section of each contact arm 4 is square, a stepped limiting step 5 is formed between each contact arm 4 and the main body 1, an inclined transition surface is arranged at the upper part of each contact arm 4 protruding out of the main body 1.
The inclined transition surface is adopted, the weight of the contact arm can be effectively reduced under the condition that the rigidity of the contact arm is not influenced, the bearing capacity of the external heat insulation sleeve is reduced, meanwhile, the contact surface between the contact arm and the external heat insulation sleeve is changed into an arc-shaped surface from an original plane, therefore, the contact of the contact arm and the external heat insulation sleeve is line contact, the heat dissipation area of the grate bar is enlarged after the line contact is changed into the line contact, the ventilation area is enlarged, and the heat dissipation effect is good. After transforming, this utility model sintering machine platform truck grid section result of use is fine. The use is verified, the bogie grate is saved by about 16% in one year; the trolley heat insulation sleeve is saved by about 19 percent, the times of replacing the trolley grate and the heat insulation sleeve are reduced, the production operation rate of the sintering machine is improved, the equipment faults and the labor intensity of production workers are reduced, the production cost is saved, and the trolley heat insulation sleeve has high economic benefit.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
