Description

Technical Field

[0001] The invention relates to the technical field of sintering machine trolleys, in particular to a trolley sealing device. Background Art

[0002] The sintering machine trolley is the main operating component of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine. It receives the sintering mixed materials in the upper horizontal section. After preheating, ignition, sintering, cooling and turning, it returns to the head wheel to form a transmission cycle to achieve the purpose of sintering materials. In the existing sintering system, the sintering machine bellows is arranged under the sintering machine trolley. After the sintering machine trolley is filled with mixed materials, it runs on the trolley tracks on both sides of the bellows. The ignition furnace ignites the top of the mixed materials, and the bellows exhaust air at the bottom of the sintering machine trolley, so that the mixed materials are sintered from the top of the sintering machine trolley to the bottom. In order to make the bellows achieve a good exhaust effect, it is necessary to ensure that there is a reliable seal between the sintering machine bellows and the sintering machine trolley, and no air leakage occurs or the air leakage is as little as possible.

[0003] A patent application with the publication number CN103353228A discloses a sintering trolley sealing device, which is provided with a positioning screw, a spring, a sliding plate groove, a sliding plate, and a cushion. The positioning screw in the sealing device suspends the sliding plate in the sliding plate groove, and a cushion and a spring are installed between the sliding plate and the sliding plate groove. The top of the positioning screw is fixed on the trolley body. Under the influence of different external forces, the cushion contacts the sliding plate groove, so that the cushion becomes U-shaped, and the two end faces of the opening end of the cushion contact the two sides of the sliding plate groove respectively. Since the cushion isolates the two sides of the sliding plate groove, it plays a role in preventing air leakage, which greatly saves energy.

[0004] Although the above technical scheme solves the problem that the free movable gaps on both sides of the swimming plate formed in the swimming plate groove of the traditional sintering machine trolley and sintering bellows sealing device are prone to form air leakage points, its sealing mostly adopts the method of contacting the elastic swimming plate arranged at the bottom of the trolley with the slideways arranged on both sides of the bellows to seal the two sides of the trolley. The contact surface of the swimming plate-slideway seal is mostly flat. Relying on the pressure of the spring above the swimming plate, the upper and lower planes are in contact with each other during relative sliding to achieve sealing. Since the slideway seal adopts the form of hard seal, during the operation of the trolley machine or chain belt machine, the running resistance is increased, the wear of the elastic slideway is accelerated, and the possibility of air leakage is increased. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0059] like Figures 1 to 11 As shown, in one embodiment of the present invention, a plurality of gratings 33 are installed inside the trolley body 1, a plurality of ventilation slots 34 are opened at the bottom of the trolley body 1, and two limit pins 35 are detachably and snap-fittedly installed on opposite sides of the trolley guardrail 29, and the bottom of the limit pins 35 is in contact with the top of the grating 33.

[0060] The provided grate bars 33 are used to support and separate the sintering materials, and the provided ventilation slots 34 can ensure the uniformity and air permeability of the materials during the sintering process. The provided limit pins 35 can limit the grate bars 33 at both ends of the top of the trolley body 1, thereby preventing the grate bars 33 from escaping from the inside of the trolley body 1 during operation, thereby ensuring the normal operation of the sintering trolley during the sintering process.

[0061] like Figures 1 to 11 As shown, in one embodiment of the present invention, two moving wheels 36 are installed on opposite sides of the trolley guardrail 2 in a symmetrical rotation manner.

[0062] The carriage body 1 can be moved by the provided moving wheels 36 .

[0063] Working principle: First, install the lower sealing component to the position of the sintering fan. Through the cooperation of the upper sealing component and the lower sealing component, the sealing contact strip 3 and the sealing contact belt 4 can be in close contact when the trolley body 1 of the sintering machine trolley passes through the sintering fan, so as to achieve sealing between the sintering machine trolley and the sintering fan, forming a nearly leak-free sealing environment, effectively preventing exhaust and side leakage, which not only significantly reduces the heat and material loss caused by exhaust, but also reduces the adverse effects of cold air introduced due to side leakage on the sintering process, ensuring the sintering temperature, and can ensure the effective increase of sintering output.

[0064] When the trolley body 1 of the sintering machine trolley passes through the sintering fan, the sealing contact strip 3 will move downward, thereby pulling the movable vertical plate 11 through the connecting block 10 to move inside the movable groove 29 inside the connecting shell 6, and making the movable pressure plate 12 move downward inside the movable groove 18 inside the upper sealing seat 5, and squeezing the reset spring 13, so that the bottom of the sealing contact strip 3 contacts the top of the sealing contact belt 4, thereby achieving sealing between the sintering machine trolley and the sintering fan, and after the trolley body 1 of the sintering machine trolley is away from the sintering fan, under the action of the elastic force of the reset spring 13, the movable pressure plate 12 will move upward inside the movable groove 8 for reset, thereby pulling the sealing contact strip 3 upward and reset through the movable vertical plate 11 and the connecting block 10, which is convenient for next use, and can make the sealing contact strip 3 in a safe position to prevent the sealing contact strip 3 from touching and being damaged by other components of the sintering machine when the sealing action is not needed.

[0065] When the trolley body 1 of the sintering machine trolley passes through the sintering fan, the second magnet strip 37 will generate suction on the first magnet strip 15, so that the sealing contact strip 3 moves downward, so that the bottom of the sealing contact strip 3 contacts the top of the sealing contact belt 4, and the sintering machine trolley and the sintering fan are sealed. When the trolley body 1 drives the sealing contact strip 3 to move, the sealing contact belt 4 moves on the outside of the rotating column 19. The sealing contact strip 3 and the sealing contact belt 4 will not move relative to each other, and will not generate friction, thereby reducing the wear between the sealing surfaces and enhancing the reliability and durability of the seal. In the form of contact sealing, during the operation of the trolley or chain conveyor, the operating resistance is reduced, the wear of the seal is delayed, and the possibility of air leakage is reduced. In addition, the sealing contact strip 3 and the sealing contact belt 4 are made of high-performance materials that are wear-resistant, high-temperature resistant, and corrosion-resistant, such as special alloys, polymer composite materials, or specially treated rubber products. They can maintain stable sealing performance in harsh working environments, greatly delay the wear rate of the seal, and extend the maintenance cycle and service life of the equipment.

[0066] When the trolley body 1 of the sintering machine trolley passes through the sintering fan, the top of the sealing arc block 24 will contact the bottom of the sealing arc strip 7, thereby cooperating with the shielding of the sealing baffle 23 to achieve sealing between the sintering machine trolley and the sintering fan, thereby improving the sealing effect. In addition, when the sealing arc block 24 is worn, it can be replaced to improve the use effect of the device. In addition, the limiting push plate 22 and the sealing baffle 23 can be released by the set mounting bolts 25, so as to facilitate the replacement of the sealing baffle 23. The replacement is simple, the structural design is reasonable, and it is easy to disassemble and install, and the maintenance is convenient. In addition, the sealing arc strip 7 and the sealing arc block 24 are made of high-performance materials that are wear-resistant, high-temperature resistant, and corrosion-resistant, such as special alloys, polymer composite materials or specially treated rubber products, which can maintain stable sealing performance in harsh working environments, greatly slow down the wear rate of the seals, and extend the maintenance cycle and service life of the equipment.

[0067] The two sealing blocks 27 can be set to seal the gap between the mounting shell 17 and the sealing contact band 4, thereby improving the sealing effect. In addition, the top of the sealing contact band 4, the top of the mounting shell 17 and the top of the sealing block 27 are all located on the same horizontal plane, which can make the contact between the sealing contact strip 3 and the sealing contact band 4 more closely fitted, ensuring that the sealing contact strip 3 and the sealing contact band 4 have a very high degree of fit, effectively reducing the existence of tiny gaps, and significantly improving the tightness of the seal.

[0068] By providing the trolley guard plate 1 2, the assembly side plate 28 and the trolley guard plate 2 29, the original integrated sintering machine trolley guard plate can be changed into a split type, which accelerates the restoration of the guard plate and saves time and labor.

[0069] The assembly side panel 28 can be installed on both sides of the trolley guardrail 2 by means of the cooperation of the assembly threaded hole 2 and the assembly bolt 1, and the assembly side panel 28 can be fixed on the top of the trolley guardrail 2, and then the trolley guardrail 3 30 can be installed on the top of the trolley guardrail 2 29 by means of the cooperation of the assembly threaded hole 2 32 and the assembly bolt 2. The structural design is reasonable, and it is easy to disassemble and install, and convenient to maintain.

[0070] The provided grate bars 33 are used to support and separate the sintering materials, and the provided ventilation slots 34 can ensure the uniformity and air permeability of the materials during the sintering process.

[0071] The limiting pins 35 can limit the grating bars 33 at both ends of the top of the trolley body 1, thereby preventing the grating bars 33 from escaping from the inside of the trolley body 1 during operation, thereby ensuring the normal operation of the sintering trolley in the sintering process.

[0072] The carriage body 1 can be moved by the provided moving wheels 36 .

[0073] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
