Description

Technical Field

[0001] The utility model relates to the technical field of steel strip production equipment, in particular to a broken strip cooling mechanism of a horizontal annealing furnace. Background Art

[0002] When the strip breaks in the annealing furnace, the use of existing technologies has the following deficiencies: There are safety hazards. During processing, the strip remaining in the furnace needs to be pulled out from the furnace entrance and exit respectively. However, due to the extremely high temperature of the strip, if the subsequent broken strip is directly pulled out from the entrance, it will be affected by the heating section, which will not only cause burns to personnel, but also damage the entrance rollers. The processing time is too long, resulting in great waste. The existing conventional technology first turns off the annealing furnace and cools it to 100°C before pulling the broken strip in the furnace out from the furnace entrance and exit respectively. This operation method makes the entire processing time as long as dozens of hours, which causes great waste of unit production capacity and energy consumption.

[0003] Through searching, it is found that the prior art with patent number: CN202530125U and patent number: CN112159894A, although both can cool the steel strip, but when the steel strip passes through the prior art before breaking, the prior art does not provide a function of tensioning the steel strip.

DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a horizontal annealing furnace broken belt cooling mechanism, comprising a box body 1, on which a belt pressing mechanism 3 is rotatably installed; the belt pressing mechanism 3 comprises a support frame 30, one end of the support frame 30 is rotatably connected to the box body 1, and the other end of the support frame 30 is connected to the box body 1 through a fastener 32; the support frame 30 is connected to a roller frame 31, and the upper part of the roller frame 31 passes through the support frame 30 through a screw 33 provided and is connected to a first nut 34 provided; the lower part of the roller frame 31 is rotatably connected to a roller 36 provided, and a spring 35 is provided between the support frame 30 and the roller frame 31, and the spring 35 is sleeved on the outside of the screw 33.

[0021] In summary, when the equipment is installed at the inlet end of the steel strip of the annealing furnace, the steel strip enters the interior of the box 1. At this time, the roller 36 tensions the steel strip under the action of the spring 35 to ensure the continuous input of the steel strip; when the steel strip breaks, the coolant is filled into the interior of the box 1, and the steel strip is pulled outward from the inlet end so that the steel strip is immersed in the coolant to cool the steel strip; and during the cooling process, the roller 36 is always pressed on the steel strip under the action of the spring 35 so that the steel strip can fully contact with the coolant to improve the cooling efficiency of the equipment and prevent the steel strip from being thrown out of the annealing furnace due to instantaneous breaking.

[0022] Furthermore, since the box body 1 is connected to the axle pin at one end of the support frame 30 through the axle pin seat 5, the belt pressing mechanism 3 can be flipped on the box body 1, so it is possible to choose whether to press the belt pressing mechanism 3 on the moving steel belt according to the needs of the user; at the same time, when the steel belt breaks, the belt pressing mechanism 3 can be rotated downward to use the belt pressing mechanism 3 to press the steel belt into the box body 1, so that the coolant in the box body 1 can cool the steel belt.

[0023] At the same time, since the box body 1 is connected to the fastener 32 through the fixed seat 9, the fastener 32 can be used to connect to the fixed seat 9 to fix the other end of the belt pressing mechanism 3 on the box body 1, so that the two ends of the belt pressing mechanism 3 are reliably fixed to ensure the roller 36's ability to press the steel belt; wherein an internal threaded hole is provided on the fixed seat 9, and the fastener 32 is preferably a bolt.

[0024] On the basis of the above scheme, since a feed port 6 is provided on one side of the box body 1, and a discharge port 7 is provided on the other side of the box body 1, and rollers 4 are rotatably installed in the discharge port 7 and the feed port 6, the rollers 4 are utilized to contact the steel belt so that the steel belt can smoothly enter and exit the box body 1.

[0025] Specifically, mounting seats 8 are provided at both ends of the feed port 6 and the discharge port 7, and the roller 4 is assembled into the feed port 6 by passing an axial pin rod 10 through the mounting seat 8. Therefore, the roller 4 can be easily disassembled and assembled by disassembling the axial pin rod 10.

[0026] At the same time, the shaft pin 10 penetrates the box body 1 and is threadedly matched with the second nut 11, so that the shaft pin 10 can be stably and reliably installed on the box body 1, thereby ensuring the stability and reliability of the roller 4 when working.

[0027] In order to improve the cooling effect of the equipment, a liquid inlet 2 is also provided on the side of the box body 1, and a liquid outlet is provided at the bottom of the box body 1. Therefore, when the liquid inlet 2 is connected to an external pump body, the coolant can be continuously pumped into the box body 1 through the pump body. At the same time, the liquid outlet provided at the bottom of the box body 1 transports the coolant to the pump body through a pipeline, so that the coolant can circulate in the box body 1 to enhance the cooling effect of the equipment.

[0028] In addition, since there are two rollers 36 and the two rollers 36 are arranged side by side on the roller frame 31, the contact area between the belt pressing mechanism 3 and the steel belt can be enlarged to ensure that the belt pressing mechanism 3 can reliably press the steel belt into the box 1. At the same time, the steel belt can also be wound around the two rollers 36, and the rolling of the rollers 36 is used to facilitate the steel belt to smoothly enter the annealing furnace. At the same time, when the steel belt breaks, since the steel belt is wound around the rollers 36, the two rollers 36 can prevent the steel belt from rebounding, and the spring 35 extends downward to reliably press the steel belt into the box 1 to avoid the steel belt being thrown out instantly due to the breakage, which may cause injuries.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
