Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a rod-dropping sealing device and equipment suitable for use between a furnace hood and a trolley railing. Background Art

[0002] The furnace hood is an important component of hot air system equipment. The sealing between the furnace hood and the pallet is one of the main factors affecting the efficiency of the hot air circulation system. Reasonable control of the sealing between the furnace hood and the pallet and reducing its air leakage rate are the basis for ensuring the utilization efficiency of the equipment's hot air system and for reducing fuel consumption and carbon emissions. Taking the sintering process as an example, the equipment used is a sintering machine. The furnace hood, trolley and bellows form the hot air system of the sintering machine. The entire system is in a negative pressure state. Only the air that enters through the surface of the material on the trolley is effective air, and the air that does not pass through the surface of the material is invalid air and leaks. The external environment inevitably leaks air into the system, which not only wastes the power consumption of the main exhaust fan, but also causes a decrease in productivity. The rod drop seal is a way to solve the sealing problem between the furnace hood and the trolley. The sealing plate of the existing rod drop seal is set on the trolley end beam, so that the part where the rod is dropped cannot be directly connected to the furnace hood frame, but is indirectly connected to the furnace hood frame through a connecting frame, resulting in reduced reliability of the rod drop seal, especially under high negative pressure conditions, the reliability of the rod drop seal is even lower, which ultimately leads to low utilization efficiency of the equipment's hot air system, or the part where the rod is dropped is set longer to connect to the furnace hood frame. The longer the part where the rod is dropped is, the more complex the structure is, and the greater the manufacturing and installation errors are, resulting in multiple trolleys being poorly sealed during travel or the dropped rods touching the rod drop sealing plate, which ultimately leads to low utilization efficiency of the equipment's hot air system.

[0003] For example, in the utility model patent with announcement number CN210464031U and titled "A New Type of Sealing Device for a Roaster Rod Dropping", a new type of sealing device for a rod dropping of a roasting machine is disclosed, which includes a rod dropper corresponding to a sealing plate of a trolley, wherein the upper part of the rod dropper is connected to a rod dropper frame through a positioning block with an impact buffering function and a positioning pin, and a wear-resistant strip is installed at the bottom of the rod dropper. Figure 1 It can be seen that a longer rod-dropping rack is provided at the rod-dropping portion to be connected to the furnace cover frame. For example, in the utility model patent with announcement number CN207066130U, entitled a rod-dropping sealing device and a roasting machine comprising the above-mentioned device, a rod-dropping sealing device is disclosed, which includes a rod-dropping, and a chamfer is provided at one end of the bottom of the rod-dropping that faces the movement direction of the trolley. The rod-dropping sealing device also includes a protective cover for blocking air leakage from the chamfer. The protective cover is an L-shaped structure, and the transverse portion of the L-shaped structure is in contact with the top of the rod-dropping, and the longitudinal portion of the L-shaped structure is in contact with the side of the rod-dropping away from the bracket, and is attached thereto. Figure 1It can be seen that the rod drop portion is elongated by setting an L-shaped protective cover, and finally connected to the furnace cover frame. By setting the rod drop portion longer to be directly connected to the furnace cover frame, the manufacturing and installation errors are large, and multiple trolleys are prone to poor sealing or rod drop contacting the rod drop sealing plate during the movement process. Figure 1 As shown, one end of the existing rod drop seal is indirectly connected to the furnace hood frame through a connecting frame, which reduces the reliability of the rod drop seal. Under high negative pressure conditions, the reliability of the rod drop seal is even lower. The other end of the existing rod drop seal is connected to the trolley end beam, and the trolley end beam and the trolley body thereunder are both provided with an extension portion extending in the direction of the trolley wheels, which increases the manufacturing cost of the trolley.

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0034] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0037] The rod drop sealing assembly 18 is arranged on one side of the trolley guardrail 17 close to the trolley wheel. The rod drop sealing assembly 18 has at least a connecting portion directly connected to the furnace hood frame 16 and a movable portion in contact with the rod drop sealing plate 2 to seal the gap between the furnace hood and the trolley guardrail 17.
