Description

Technical Field

[0001] This utility model relates to the field of steel rolling equipment technology, and in particular to a cooling device with adjustable air volume. Background Technology

[0002] With increased government attention and policy support, the cold heading steel market is expected to continue its growth. Depending on the needs of different customers, certain niche products have specific requirements for plastic deformation, emphasizing excellent ductility. Therefore, temperature control in the latter part of product development, specifically the cooling process for finished products, becomes crucial.

[0003] Currently, steel companies use an air-cooling method where a fan forces cool air through an air duct, which then blows it directly onto the hot wire rods from nozzles at the end of the duct, thus cooling the rods. The fan is installed inside a fan chamber. When the fan is running, outside cool air enters the fan chamber through the inlet, is then blown into the air duct, and exits from the end of the duct. Because the fan's airflow is fixed, it is only suitable for cooling wire rods of one material.

[0004] If the material of the wire rod changes, the required cooling rate also needs to be changed according to the production process requirements; otherwise, it will affect the product quality. Therefore, this constant air volume cooling method cannot meet the requirements.

[0005] Patent CN211437494U discloses a rapid cooling device for high-speed wire rods, including a pneumatic atomizing nozzle assembly, a fan, and a mist suction hood; the pneumatic atomizing nozzle assembly is used to spray water onto the wire rod. Because the fan's airflow is not adjustable, the flow rate of the water mist blown onto the wire rod is also fixed. Since different wire materials have different process requirements for cooling speed, this device can only be used to produce wire rods of one material. Patent CN204817495U discloses a controlled cooling device for high-carbon steel wire rods after rolling, which uses a fan to blow air mist onto the wire rod to cool it. However, because the fan's airflow is uncontrollable, it also suffers from the problem of being applicable only to wire rods of one material. Utility Model Content

[0006] The purpose of this invention is to provide a cooling device with adjustable airflow, which adjusts the airflow according to the cooling rate required by different materials of the coil, thereby meeting the cooling process requirements of the corresponding material of the coil and ensuring product quality.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An adjustable cooling device includes a fan chamber, an air duct connected to the top of the fan chamber, and an air outlet provided at the air outlet of the air duct. A fan is installed in the fan chamber, and an air inlet is provided on the fan chamber. At least two baffles are provided on the air inlet to change the flow area of ​​the air inlet. The baffles are all connected to the fan chamber.

[0009] Furthermore, the air inlet is circular, and the fan chamber is provided with an air inlet ring that fits around the air inlet. The air inlet ring is fixedly connected to the fan chamber, and a central tube is provided at the center of the air inlet ring. The baffles are all fan-shaped and are evenly distributed between the air inlet ring and the central tube along the circumference. The two ends of the baffles are rotatably connected to the air inlet ring and the central tube, respectively. The fan chamber is provided with an adjustment unit for adjusting the tilt angle of each baffle.

[0010] Furthermore, each wind deflector is fixedly connected to a rotating shaft at its outer end. The rotating shaft is rotatably connected to the air inlet ring. Each rotating shaft is equipped with a swing arm, which is evenly distributed along the circumference. The inner end of the swing arm is fixedly connected to the rotating shaft. A tension member is connected between the outer ends of adjacent swing arms. The fan chamber is equipped with a drive mechanism for driving one of the swing arms to swing.

[0011] Furthermore, the supporting component is a cable, which is wound around the outside of the air inlet ring, and the outer ends of the swing arms are all fixedly connected to the cable.

[0012] Furthermore, the driving mechanism is a rotary motor, and the output shaft of the rotary motor is connected to one of the rotary shafts in a transmission connection.

[0013] Furthermore, the wind deflector consists of two interlocking semicircles that block the air inlet, and the wind deflector is detachably connected to the fan chamber.

[0014] Furthermore, ventilation holes are provided between the wind deflectors, and the ventilation holes are located at the center of the air inlet.

[0015] Furthermore, a mesh cover is fixedly connected to the fan chamber, and the baffle plate, air inlet ring and central tube are all covered inside the mesh cover.

[0016] The positive effects of this utility model are:

[0017] This invention features an air inlet ring on the fan chamber, within which fan-shaped baffles are distributed circumferentially. The fan chamber is equipped with a drive mechanism to change the angle of the baffles. By changing the angle of the baffles through the drive mechanism, the flow area of ​​the air inlet in the fan chamber is altered, thereby changing the fan's airflow. This allows the fan's airflow to be adapted to different materials and materials requiring varying airflow volumes, ensuring the quality of the coiled wire. Attached Figure Description

[0025] Example 1

[0026] like Figures 1 to 4 As shown, a cooling device with adjustable airflow includes a rectangular fan chamber 1, an air duct 6 inclinedly connected to the top of the fan chamber 1, and air outlets 7 located at the air outlet at the top of the air duct 6. The air outlets 7 are five slits located at the top of the air duct 6. A fan is installed inside the fan chamber 1, and an air inlet is provided on the front side of the fan chamber 1. Twenty-four baffles 3 are covered in front of the air inlet, and all the baffles 3 are connected to the fan chamber 1.

[0027] The fan's air intake is connected to the air inlet. When the fan is running, cold air from the outside enters the fan through the air inlet, and then is blown out through the air outlet 7 through the air duct 6, blowing towards the high-temperature coils to cool them down.

[0028] The air inlet is circular. A circular air inlet ring 4, fitted around the air inlet, is located on the front side of the fan chamber 1. The air inlet ring 4 is fixedly connected to the fan chamber 1. A central tube 5, coaxial with the air inlet ring 4, is located at the center of the ring. Ventilation holes 12 are located inside the central tube 5. The rear side of the central tube 5 is fixedly connected to the air inlet ring 4 via a reinforcing rib. All the baffle plates 3 are fan-shaped. The air inlet ring 4 and the central tube 5 are fitted with the baffle plates 3 with clearance. Twenty-four baffle plates 3 are evenly distributed circumferentially between the air inlet ring 4 and the central tube 5. The rotation axis of each baffle plate 3 passes through the center of the air inlet ring 4. Both ends of each baffle plate 3 are rotatably connected to the air inlet ring 4 and the central tube 5, respectively. The fan chamber 1 is equipped with an adjustment unit for adjusting the tilt angle of each baffle plate 3.

[0029] The adjustment unit can adjust the flow area of ​​the air inlet ring 4 by adjusting the angle of the baffle plate 3, thereby adjusting the air intake of the fan and adjusting the air volume blown onto the wire rod, thus making it suitable for wire rods of different materials.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that:

[0032] Each wind deflector 3 has a fixedly connected rotating shaft 11 at its outer end. Each rotating shaft 11 is rotatably connected to the air inlet ring 4. Each rotating shaft 11 is equipped with a swing arm 10, which is evenly distributed along the circumference of the air inlet ring 4. The inner end of each swing arm 10 is fixedly connected to the outer end of the rotating shaft 11. A tension member 9, which is a flexible cable such as a steel wire rope, is connected between the outer ends of adjacent swing arms 10. The steel wire rope is wrapped in a closed loop around the air inlet ring 4, and the outer ends of each swing arm 10 are fixedly connected to the cable. The fan chamber 1 is equipped with a drive mechanism 8 for swinging one of the swing arms 10. The drive mechanism 8 is a rotary motor fixedly connected to the front side of the fan chamber 1, and the output shaft of the rotary motor is connected to one of the rotating shafts 11 via a coupling.

[0033] When the angle motor is working, it drives the corresponding swing arm 10 to swing through the rotating shaft 11, and then pulls the wire rope, causing the wire rope to rotate around the air intake ring 4, driving each swing arm 10 to swing synchronously, so that the swing arm 10 moves from... Figure 3 The tilted state shown swings 90 degrees to reach Figure 4 As shown, the wind deflector 3 is in the state indicated. Figure 3 As shown, it reaches perpendicularly to the axis of the air inlet ring 4. Figure 4 As shown, the air inlet ring 4 is parallel to the fan, and during this process, the fan's airflow increases from minimum to maximum. During this process, the tilt angle of the baffle 3 can be controlled by controlling the rotary motor, thereby allowing for stepless adjustment of the fan's airflow to suit different materials of wire rod.

[0034] A circular mesh cover 2 is fixedly connected to the fan chamber 1. The wind baffle 3, the air inlet ring 4 and the central tube 5 are all covered inside the mesh cover 2, and the corner motor is located outside the mesh cover 2.

[0035] In addition, the swing arm 10 can be made of elastic steel, so that the wire rope is always kept taut, preventing the wind deflector 3 from swaying or vibrating due to wind force, thus generating excessive noise.

[0036] Example 3

[0037] like Figure 5 As shown, an adjustable airflow cooling device includes a rectangular fan chamber 1, an air duct 6 inclinedly connected to the top of the fan chamber 1, and air outlets 7 located at the air outlet at the top of the air duct 6. The air outlets 7 are five slits located at the top of the air duct 6. A fan is installed inside the fan chamber 1, and an air inlet is provided on the front side of the fan chamber 1. The front cover of the air inlet has two baffles 3 for changing the flow area of ​​the air inlet, and the baffles 3 are connected to the fan chamber 1.

[0038] The two wind deflectors 3 are interlocking semicircles, which block the air inlet. Each wind deflector 3 is detachably connected to the fan chamber 1 by four buckles 13. After the two wind deflectors 3 are fastened together, the center of the two wind deflectors 3 is the ventilation hole 12.

[0039] After unfastening the pull tab 13, the baffle plate 3 can be removed, thereby changing the flow area of ​​the air inlet and thus changing the air volume of the fan.
