Description

Technical Field

[0001] The present application relates to the technical field of concrete curing, and specifically to an air supply duct for a concrete curing kiln. Background Art

[0002] When a concrete curing kiln is in use, generally, concrete cured products are placed in the front curing chamber of the curing kiln. After the front curing chamber is full, they are then placed in the subsequent curing chamber. This results in the number of concrete products to be cured in the front curing chamber being greater than that in the rear curing chamber.

[0003] Traditional concrete curing kilns generally consist of multiple sequentially connected curing chambers, a main air duct, and branch ducts communicating with the main air duct and the curing chambers. Although the main air duct and the branch ducts can send hot air into the curing chambers to cure the concrete products, it is difficult to control the air intake volume of the front curing chamber, which affects the curing efficiency and product quality of the concrete products.

[0004] Therefore, the present application provides an air supply duct for a concrete curing kiln to solve the above problems. Utility Model Content

[0005] The present application provides an air supply duct for a concrete curing kiln, aiming to solve the problem in the background art that the existing air supply duct of the concrete curing kiln is difficult to control the air intake volume of the front curing chamber, which affects the curing efficiency and product quality of the concrete products.

[0006] To achieve the above object, the present application provides the following technical solution: An air supply duct for a concrete curing kiln includes a main air duct and at least two branch ducts provided on the main air duct for communicating with the curing chambers of the curing kiln. One end of the main air duct has an air inlet; it further includes a rotating shaft rotatably provided inside the main air duct at a position corresponding to the side of the branch duct away from the air inlet, a wind deflector provided on the rotating shaft, and a driving mechanism provided on the main air duct for driving the rotating shaft to rotate. In this way, by driving the rotating shaft to rotate through the driving mechanism and adjusting the angle of the wind deflector, the air intake volume of the front curing chamber can be changed, realizing the air intake adjustment of the front curing chamber. Furthermore, the air intake volume of the front curing chamber can be adjusted according to the curing requirements, improving the curing efficiency and product quality of the concrete products.

[0007] Preferably, the areas of several wind deflectors increase sequentially from the end of the main air duct close to the air inlet to the end of the main air duct away from the air inlet.

[0008] Preferably, the driving mechanism includes a connecting rod provided on one side of the main air duct, a connecting piece fixedly provided at one end of the rotating shaft and hinged to the connecting rod, and a driving member provided on the main air duct for driving the connecting rod to float along the length direction of the main air duct.

[0009] Preferably, the driving member includes a servo motor fixedly installed on the main air duct and an eccentric rod fixedly installed on the output shaft of the servo motor for floating the connecting rod along the length direction of the main air duct.

[0010] Preferably, one end of the eccentric rod away from the servo motor has a pin shaft penetrating through the connecting rod, and a long waist hole adapted to the pin shaft is formed on the connecting rod.

[0011] The air supply duct structure of the concrete curing kiln is simple and convenient to use. By arranging a wind baffle on the side of the main air duct corresponding to the branch duct away from the air inlet, and adjusting the angle of the wind baffle by controlling the driving structure, the incoming air enters the front curing chamber from the air inlet of the branch duct, so as to ensure the air intake volume of the curing chamber connected to the branch duct, and further improve the curing efficiency and product quality of the concrete products in the front curing chamber.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The present application provides an air supply duct for a concrete curing kiln, as Figure 1 and Figure 2 shown. The air supply duct includes a main air duct 1 and at least two branch ducts 2 disposed on the main air duct 1 and communicating with the curing chamber of the curing kiln. One end of the main air duct 1 has an air inlet 11; it further includes a rotating shaft 3 rotatably disposed inside the main air duct 1 at a position corresponding to the side of the branch duct 2 away from the air inlet 11, a wind deflector 4 disposed on the rotating shaft 3, and a driving mechanism 5 disposed on the main air duct 1 for driving the rotating shaft 3 to rotate.

[0032] During use, according to the curing needs of the front curing chamber, the angle of the wind deflector 4 can be adjusted through the driving mechanism 5. Under the action of the wind deflector 4, the hot air entering from the air inlet 11 is blocked. When the wind deflector 4 contacts the incoming air, the hot air enters the front curing chamber from the air inlet of the branch duct 2 under the action of the wind deflector 4, ensuring the air intake volume entering the front curing chamber and improving the curing efficiency and product quality of the front curing chamber.

[0033] It can be understood that the larger the angle between the wind deflector 4 and the incoming air direction of the main air duct 1, the larger the air intake volume at the air inlet port of the branch duct 2 at the front end of the wind deflector 4. When the wind deflector 4 is perpendicular to the incoming air direction, the contact area between the wind deflector 4 and the incoming air is the largest. At this time, the air intake volume entering the curing chamber through the air inlet of the branch duct 2 is the largest.

[0034] It is worth mentioning that due to the action of the wind deflector 4, the air intake volume of the front curing chamber increases. Under the same air supply pressure, the air supply pressure at the rear end of the curing chamber is reduced due to the action of the wind deflector 4, resulting in a decrease in the air supply pressure at the rear end. To ensure the air intake volume of the rear curing chamber, the areas of several wind deflectors 4 increase in sequence from the end of the main air duct 1 close to the air inlet 11 to the end of the main air duct 1 far from the air inlet 11; by increasing the area of the subsequent wind deflectors 4, the rear-end air supply pressure is compensated to compensate for the air supply pressure at the rear curing chamber, thereby ensuring the air intake volume of the subsequent curing chambers.

[0035] Specifically, as Figure 1 and Figure 2 and Figure 3As shown in the figure, the driving mechanism 5 includes a connecting rod 51 disposed on one side of the main air duct 1, a connecting piece 52 fixedly arranged at one end of the rotating shaft 3 and hinged to the connecting rod 51, and a driving member 53 disposed on the main air duct 1 for driving the connecting rod 51 to float along the length direction of the main air duct 1.

[0036] When adjusting the air intake volume of the curing chamber, the driving member 53 drives the connecting rod 51 to float along the length direction of the main air duct 1, thereby pushing or pulling the connecting piece 52 to rotate on the main air duct 1, driving the rotating shaft 3 to rotate, and enabling the wind deflector 4 to rotate inside the main air duct 1 along with the rotating shaft 3, adjusting the angle between the wind deflector 4 and the air inlet direction of the main air duct 1, changing the contact pressure between the hot air and the wind deflector 4, and thus realizing the adjustment of the air intake volume of the branch pipe 1.

[0037] More specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the driving member 53 includes a servo motor 531 fixedly installed on the main air duct 1 and an eccentric rod 532 fixedly installed on the output shaft of the servo motor 531 for enabling the connecting rod 51 to float along the length direction of the main air duct 1. Among them, one end of the eccentric rod 532 away from the servo motor 531 has a pin shaft 533 passing through the connecting rod 51, and a long waist hole 511 adapted to the pin shaft 533 is formed on the connecting rod 51.

[0038] When driving the connecting rod 51 to float, the servo motor 531 drives the eccentric rod 532 to rotate, first driving the connecting rod 51 to float in the height direction of the main air duct 1, and then under the action of the pin shaft 533 and the inner wall of the long waist hole 511, enabling the connecting rod 51 to move along the length direction of the main air duct 1 under the action of the eccentric rod 532, thereby pushing or pulling the connecting piece 52 to rotate, driving the rotating shaft 3 to rotate, and driving the wind deflector 4 to rotate, realizing the adjustment of the wind deflector 4.

[0039] As mentioned above, the above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present application.
