[0002] In the firing process of ceramic brick products, the kiln is used to sinter the ceramic brick blanks at high temperature. The kiln is equipped with an air duct system to control the temperature, atmosphere and heat exchange efficiency inside the kiln. The air ducts are arranged around the kiln and the air volume entering the kiln is regulated by the air damper device.

[0003] In the existing technology, because the kiln is actively set in the boundary area of ​​the plant, the installation position of some air ducts and air dampers is close to the side columns or side walls of the plant, resulting in narrow operating space. This leads to problems such as inconvenience in adjusting the air dampers and difficulty in manual operation, thus affecting the timeliness of air volume control. In addition, the existing air damper devices have a single adjustment method and cannot flexibly switch between manual and automatic control modes. When electrical control failure occurs or on-site manual operation is required, it is often difficult to adjust the air volume in a timely manner, thus affecting the operational stability of the kiln.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0012] Using the above technical solution, in the air damper device with easily adjustable duct opening, the tension adjustment mechanism includes a fixed base, a second handwheel, a second lead screw shaft, a threaded sleeve, and a third pulley;

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 4 As shown, this utility model embodiment provides an air damper device for easily adjusting the opening of an air duct, including a valve housing 1, a mounting bracket 2, a gate plate 3, a first lead screw shaft 4, a first handwheel 5, a drive motor 6, a transmission belt 7, and a tension adjustment mechanism 8. The valve housing 1 is used to connect to the air duct, and the valve housing 1 is provided with a ventilation opening 10. The mounting bracket 2 is disposed on the valve housing 1, and the mounting bracket 2 has first slide rails 21 on both sides. The side end of the gate plate 3 abuts against the first slide rails 21 and can move up and down along the extension direction of the first slide rails 21 to adjust the opening size of the ventilation opening 10. The first lead screw shaft 4 is rotatably mounted on the mounting bracket 2, and the first lead screw shaft 4 is connected to the gate plate 3 through the threaded seat 41. The gate plate 3 is used to move along the first slide rail 21 as the first lead screw shaft 4 rotates. When it is necessary to adjust the airflow in the duct, the operator can drive the first lead screw shaft 4 to rotate, thereby converting its rotational motion into the linear motion of the threaded seat 41, which in turn drives the gate plate 3 connected to it to move in the up and down direction. Specifically, as the gate plate 3 rises, the opening of the vent 10 gradually increases, and the airflow increases accordingly; conversely, when the gate plate 3 falls, it can gradually block the vent 10, and the airflow decreases accordingly.

[0032] The first lead screw shaft 4 is provided with a first bevel gear 42 at its top, and the first handwheel 5 is provided at the top of the mounting bracket 2. The output shaft of the first handwheel 5 is provided with a second bevel gear 43. The first bevel gear 42 and the second bevel gear 43 are meshed and connected. The first handwheel 5 is used to drive the first lead screw shaft 4 to rotate. When the operator rotates the first handwheel 5 clockwise, the second bevel gear 43 can drive the first bevel gear 42, which meshes with it, to rotate, thereby driving the first lead screw shaft 4 to rotate. Since the first lead screw shaft 4 is connected to the gate plate 3 through the threaded seat 41, the gate plate 3 is driven to move linearly along the direction of the first slide rail 21, thereby realizing manual adjustment of the opening of the ventilation port 10.

[0033] The drive motor 6 is located on the side of the mounting bracket 2. The output shaft of the drive motor 6 has a first pulley 61, and the bottom of the first bevel gear 42 has a second pulley 62. The first pulley 61 and the second pulley 62 are connected by the transmission belt 7. The drive motor 6 drives the first lead screw shaft 4 to rotate. The tension adjustment mechanism 8 is connected to the transmission belt 7 and is used to adjust the tension of the transmission belt 7. The tension adjustment mechanism 8 can switch between manual and automatic operation by adjusting the tension of the transmission belt 7. Specifically, when the tension adjustment mechanism 8 is in the tensioned state, the transmission belt 7 maintains tension. At this time, when the drive motor 6 rotates, it can drive the first lead screw shaft 4 to rotate, thereby realizing the automatic adjustment of the gate 3. When the tension adjustment mechanism 8 is released, and the transmission belt 7 is in the slack state, the first lead screw shaft 4 is no longer driven by the drive motor 6. At this time, the gate 3 can be manually adjusted by manually operating the first handwheel 5. This setting allows the windshield device to have flexible switching and adjustment capabilities when used under abnormal power supply conditions.

[0034] like Figure 4As shown, the tension adjustment mechanism 8 further includes a fixed base 81, a second handwheel 82, a second lead screw shaft 83, a threaded sleeve 84, and a third pulley 85. The fixed base 81 is located on the top of the mounting frame 2, and the threaded sleeve 84 is located on the fixed base 81. The second lead screw shaft 83 and the threaded sleeve 84 are connected by threads. The second handwheel 82 is located at one end of the second lead screw shaft 83 and is used to drive the second lead screw shaft 83 to move telescopically along the threaded sleeve 84. The other end of the second lead screw shaft 83 is provided with a fixed bracket 86, and the third pulley 85 is located on the fixed bracket 86. The third pulley 85 is sleeved on the third pulley 85 and is used to tighten or release the transmission belt 7 as the second lead screw shaft 83 moves telescopically. When the operator turns the second handwheel 82, the second lead screw shaft 83 moves forward or backward along the thread direction, thereby driving the third pulley 85 to move as well, thus adjusting the tension of the transmission belt 7. Specifically, when the second lead screw shaft 83 drives the third pulley 85 to move outward, the transmission belt 7 is tightened, and the power output by the drive motor 6 can be transmitted to the first lead screw shaft 4 to achieve automatic adjustment of the air damper. When the second lead screw shaft 83 rotates in the opposite direction, causing the third pulley 85 to retract inward, the transmission belt 7 becomes loose, and the power of the drive motor 6 cannot be transmitted to the first lead screw shaft 4. The operator can manually adjust the opening of the gate 3 through the first handwheel 5.

[0035] like Figure 4 As shown, the tension adjustment mechanism 8 further includes a second slide rail 87, which is mounted on the fixed base 81. The bottom of the fixed bracket 86 is provided with a slide groove that is slidably connected to the second slide rail 87. This arrangement can improve the movement accuracy of the third pulley 85 and prevent the third pulley 85 from being unbalanced or shaking during telescopic movement.

[0036] like Figure 3 As shown, it further includes a bearing seat 44, which is sleeved and connected to the end of the first lead screw shaft 4. The bearing seat 44 can improve the rotational stability of the first lead screw shaft 4.

[0037] like Figure 1 and Figure 2 As shown, the valve housing 1 is further provided with a plurality of connecting through holes 11 along the axial direction, and the connecting through holes 11 are used to be connected to the flange of the air duct by bolts.

[0038] Furthermore, the drive motor 6 is a servo motor.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
