Description

Technical Field

[0001] This utility model relates to the field of steel bar production equipment technology, and more specifically, to a cooling device for a steel bar production line. Background Technology

[0002] Reinforcing bars are strip-shaped products, usually made of low-carbon steel, used to reinforce concrete structures. They bear tensile forces in the concrete and, together with other reinforcing bars, form a skeleton to increase the strength and stability of the structure. Reinforcing bars are weldable, allowing them to be connected and arranged when constructing large projects such as bridges and skyscrapers. They are also used to manufacture various types of reinforcing mesh and reinforcing cages to meet the needs of different buildings and projects. During the production process of reinforcing bars, cooling devices are required to cool them.

[0003] For example, Chinese Patent Publication No. CN201921174201.8 discloses a cooling device for a coated steel bar production line. The device includes a cooling tank with a conveying device located below the water level. The cooling tank is connected to a circulating water cooling system, which cools the coated steel bars using circulating water. The cooling tank comprises a central section and a return water section. Multiple water inlets are spaced apart at the bottom of the central section. Each return water section has a first return water inlet at its bottom. The sidewalls of the central section are higher than those of the return water section to facilitate the flow of circulating water from the central section to the return water section. The coated steel bars exchange heat through contact with water, resulting in a large contact area. The return water at both ends of the cooling tank ensures sufficient contact between the circulating water and the coated steel bars, guaranteeing effective cooling and facilitating continuous production.

[0004] However, in the above technical solutions, the cooling process in the steel bar production line is crucial to the performance and surface quality of the steel bars. Traditional cooling devices mostly use spraying or immersion to achieve cooling, but after cooling, moisture and oxide slag are easily left on the surface of the steel bars. The retention of moisture not only causes the risk of rust, but the damp surface may also adhere to impurities during subsequent transportation or processing, increasing the probability of secondary pollution. If oxide slag (such as iron oxide scale generated during rolling) is not removed in time, it may fall off onto the production line or the surface of the finished product, affecting the processing accuracy and product appearance, and even polluting the environment. Utility Model Content

[0005] The main purpose of this utility model is to provide a cooling device for a steel bar production line, which can effectively solve the problem in the background art where the cooling process in the steel bar production line is crucial to the performance and surface quality of the steel bars. Traditional cooling devices mostly use spraying or immersion to achieve cooling, but after cooling, moisture and oxide slag are easily left on the surface of the steel bars. The retention of moisture not only causes the risk of rust, but the damp surface may also adhere to impurities during subsequent transportation or processing, increasing the probability of secondary pollution. If oxide slag (such as iron oxide scale generated during rolling) is not removed in time, it may fall off onto the production line or the surface of the finished product, affecting the processing accuracy and product appearance, and even polluting the environment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cooling device for a steel bar production line, comprising a base, a first groove provided on the base, an installation block and several conveying rollers provided in the first groove, a second groove provided on the installation block, a cleaning component provided in the second groove, an annular air conveying groove provided on the inner wall of the second groove, an air pump provided on one side of the annular air conveying groove, a motor fixedly installed on one side of the installation block, a gear provided on the rotating output part of the motor, several water spray pipes provided on one side of the base, and several sealing layers provided on the inner wall surface of the second groove.

[0007] Preferably, the air pump is fixedly mounted on the mounting block.

[0008] Preferably, the cleaning component includes a component base, on which a through groove is provided, and a plurality of cleaning brushes are fixedly disposed on the inner wall surface of the through groove.

[0009] Preferably, the component base is provided with an annular toothed groove and several air supply grooves on one side, and an air outlet is provided on one side of the air supply grooves.

[0010] Preferably, the component base is rotatably disposed in the second groove, the gear meshes with the annular tooth groove, and the air outlet is inclined.

[0011] Preferably, the two sides of the air outlet are connected to the air delivery channel and the through channel, respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) After cooling the steel bars, the cooled steel bars are sent into the through groove. At this time, the air is input into the annular air conveying groove by the air pump. Then, the air in the annular air conveying groove is transported to the air outlet through the air conveying groove. The air outlet guides the air to the surface of the steel bars, blows away the water droplets on the surface of the steel bars, and dries the surface of the steel bars quickly, which facilitates the subsequent processing of the steel bars. Then, the motor drives the gear to rotate, and the gear and the annular tooth groove drive the component base to rotate. The air outlet and the cleaning brush follow the rotation of the component base. The rotating air outlets are used to thoroughly dry the surface of the steel bars. Then, the rotating cleaning brush is used to clean the oxide residue attached to the surface of the steel bars, reducing secondary pollution in subsequent processes. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2As shown, a cooling device for a steel bar production line includes a base 1, a first groove 2 on the base 1, an mounting block 3 and several conveying rollers 4 inside the first groove 2, a second groove 5 on the mounting block 3, a cleaning component 6 inside the second groove 5, an annular air conveying groove 7 on the inner wall of the second groove 5, an air pump 8 on one side of the annular air conveying groove 7, a motor 9 fixedly mounted on one side of the mounting block 3, a gear 10 on the rotation output part of the motor 9, several water spray pipes 11 on one side of the base 1, and several sealing layers 12 on the inner wall surface of the second groove 5.

[0020] like Figure 3 As shown, in another embodiment of the present invention, the cleaning component 6 includes a component base 601, a through groove 602 is provided on the component base 601, and a plurality of cleaning brushes 603 are fixedly provided on the inner wall surface of the through groove 602.

[0021] The component base 601 is provided with an annular toothed groove 604 and several air supply grooves 605 on one side, and an air outlet 606 is provided on one side of the air supply grooves 605.

[0022] When cleaning the surface of the reinforcing steel is required, the airflow in the annular air delivery channel 7 is first delivered to the air outlet 606 through the air delivery channel 605. Then, the water-cooled reinforcing steel passes through the through channel 602, and the air outlet 606 guides the airflow to the surface of the reinforcing steel, blowing away the water droplets on the surface of the reinforcing steel and quickly drying the surface of the reinforcing steel, which is convenient for subsequent processing of the reinforcing steel. At the same time, the inclined air outlet 606 blows the water droplets on the surface of the reinforcing steel away from the cleaning brush 603, preventing water droplets from splashing onto the cleaning brush 603 and affecting it. Meanwhile, the component base 601 is rotated by the gear 10 and the annular toothed groove 604. The air outlet 606 and the cleaning brush 603 rotate with the component base 601. The rotating air outlets 606 thoroughly dry the surface of the reinforcing steel. Then, the rotating cleaning brush 603 cleans the oxide residue attached to the surface of the reinforcing steel, reducing secondary pollution in subsequent processes.

[0023] The working principle of a cooling device for a steel bar production line:

[0024] In use, the reinforcing bars are placed on the conveying roller 4 for transport, and the surface of the reinforcing bars is sprayed with cooling water by the water spray pipe 11 to cool them. The cooled reinforcing bars are then sent into the through groove 602. At this time, the air pump 8 inputs air into the annular air conveying groove 7, and then the air in the annular air conveying groove 7 is delivered to the air outlet 606 through the air conveying groove 605. The air outlet 606 guides the air to the surface of the reinforcing bars, blowing away the water droplets on the surface of the reinforcing bars and quickly drying the surface of the reinforcing bars, which is convenient for subsequent processing. Then, the motor 9 drives the gear 10 to rotate, and the gear 10 and the annular tooth groove 604 drive the component base 601 to rotate. The air outlet 606 and the cleaning brush 603 rotate with the component base 601, and the rotating air outlets 606 thoroughly dry the surface of the reinforcing bars. Then, the rotating cleaning brush 603 cleans the oxide residue attached to the surface of the reinforcing bars, reducing secondary pollution in subsequent processes.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
