Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, specifically to a grate cooler air outlet device with controllable air volume. Background Technology

[0002] A grate cooler is a type of rapid cooling cooler. After the clinker enters the cooler from the kiln, it is laid in a layer of a certain thickness on the grate. Cold air is blown in and passes through the moving material layer on the grate in a direction perpendicular to each other, thus rapidly cooling the clinker.

[0003] The existing Chinese utility model patent with publication number CN222211288U discloses an adjustable exhaust volume grate cooler, relating to the field of grate cooler technology. It includes a grate bed with an air-adjusting mechanism on its upper surface. The mechanism includes ventilation slots formed on the upper surface of the grate bed. A fixed chamber is fixedly connected to the upper surface of the grate bed, and a threaded rod is rotatably connected to the inner wall of the chamber. Four threaded rings are threaded onto the outer surface of the threaded rod, and an inclined plate is fixedly connected to the outer surface of each threaded ring. This utility model uses a servo motor to drive the threaded rod to rotate. During rotation, the threaded rod interacts with the four threaded rings, causing the rings to move left and right via the inclined plates, which in turn move the baffles. This left-right movement of the inclined plates partially or completely obstructs the ventilation slots, thus changing their size. This adjustable ventilation slot size allows for regulation of the cold air passing through it, enabling the overall airflow of the grate cooler to be adjusted according to the actual cooling needs of cement raw materials, facilitating its use.

[0004] Existing grate coolers typically adjust the airflow by tilting the baffles. Due to the influence of air pressure, the baffle structure may bend under the influence of pressure difference. Furthermore, the existing adjustment structure can only be adjusted synchronously and cannot finely adjust the airflow of each area according to usage requirements. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a grate cooler air outlet device with controllable air volume, which has the advantages of multi-level zone adjustment and prevention of baffle deformation, thus solving the above-mentioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a grate cooler air outlet device with controllable airflow, comprising: a diversion chamber, air inlets on both sides of the diversion chamber, a limiting frame fixedly installed above the diversion chamber, a connecting shaft inserted inside the limiting frame, a baffle movably installed above the connecting shaft, a reinforcing rib above the baffle, a reinforcing plate fixedly installed inside the baffle, a connecting block fixedly installed below the baffle, a transmission rod movably installed below the connecting block, a transmission frame movably installed at the bottom end of the transmission rod, a support block movably installed below the transmission frame, and a hydraulic cylinder fixedly installed below the support block; the diversion chamber can restrict airflow from passing between the baffles.

[0009] As a preferred technical solution of this utility model, the air inlet is equidistant from the center of the diversion chamber and is symmetrically arranged on the left and right sides of the diversion chamber; the air inlet facilitates the connection between the diversion chamber and the fan.

[0010] As a preferred technical solution of this utility model, the bottom of the limiting frame is provided with rod-shaped structures with equal spacing, and the left and right sides of the limiting frame are provided with cylindrical openings that fit into the connecting shaft; the limiting frame can limit the distance between the connecting shafts.

[0011] As a preferred embodiment of this utility model, the connecting shaft is installed equidistantly in the cylindrical opening of the limiting frame, and the connecting shaft and the limiting frame are fixedly connected, while the baffle and the connecting shaft are rotatably connected; the connecting shaft facilitates the rotation of the baffle.

[0012] As a preferred embodiment of this utility model, the reinforcing ribs are equidistantly arranged on the upper and lower sides of the baffle, and the reinforcing plate is fixed to the inside of the baffle by welding at equidistant intervals; the reinforcing ribs can increase the strength of the baffle.

[0013] As a preferred embodiment of this utility model, the connecting block is installed at equal intervals on the left and right ends of the front side of the bottom of the baffle, with the center of the baffle as the reference. Columnar protrusions are provided on the left and right sides of both ends of the transmission rod. The connecting block facilitates the connection between the baffle and the transmission rod.

[0014] As a preferred embodiment of this utility model, the transmission rod is rotatably connected to the upper connecting block and the lower transmission frame, and the bottom end of the hydraulic cylinder is fixedly connected to the bottom surface of the diversion chamber; the hydraulic cylinder can drive the transmission frame to move.

[0015] Compared with the prior art, this utility model provides a grate cooler outlet device with controllable air volume, which has the following beneficial effects:

[0016] 1. This utility model increases the thickness of the baffle by setting a baffle and opening a hole in the center of the baffle, so that the reinforcing plate can be fixed inside the baffle by welding. At the same time, the reinforcing ribs are set at equal intervals on the left and right sides of the baffle center. When the fan blows air into the distribution chamber, the force generated by the air pressure difference will be transmitted to the internal reinforcing plate and the upper reinforcing ribs, thereby increasing the rigidity of the baffle and preventing the baffle from deforming under the action of air pressure difference, causing the baffle to bend upward and affecting the control of gas flow.

[0017] 2. This utility model uses a hydraulic cylinder to connect the transmission rod to the baffle via a connecting block. Since the bottom end of the transmission rod is rotatably connected to the transmission frame, and the transmission frame is fixedly connected to the movable end of the hydraulic cylinder via a support block, the transmission frame moves up and down during the extension and retraction of the hydraulic cylinder. This allows the transmission rod to adjust the opening and closing angle of the baffle. The transmission rod will tilt during this adjustment process, and the baffle is controlled by the corresponding hydraulic cylinder below. By adjusting the extension of a single hydraulic cylinder, the opening and closing angle of a single baffle is controlled, achieving precise adjustment of the airflow in each area.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a grate cooler air outlet device with controllable air volume includes: a diversion chamber 1, air inlets 11 on both sides of the diversion chamber 1, a limit frame 12 fixedly installed above the diversion chamber 1, a connecting shaft 13 inserted inside the limit frame 12, a baffle 14 movably installed above the connecting shaft 13, a reinforcing rib 15 above the baffle 14, a reinforcing plate 16 fixedly installed inside the baffle 14, a connecting block 17 fixedly installed below the baffle 14, a transmission rod 18 movably installed below the connecting block 17, a transmission frame 19 movably installed at the bottom end of the transmission rod 18, a support block 110 movably installed below the transmission frame 19, and a hydraulic cylinder 111 fixedly installed below the support block 110.

[0027] The air inlet 11 is equidistant from the center of the diversion chamber 1 and symmetrically mirrored on the left and right sides of the diversion chamber 1. The bottom of the limiting frame 12 is provided with rod-shaped structures with equal spacing. The left and right sides of the limiting frame 12 are provided with cylindrical openings that fit into the connecting shaft 13. The connecting shaft 13 is installed equidistantly inside the cylindrical openings of the limiting frame 12, and the connecting shaft 13 and the limiting frame 12 are fixedly connected. The baffle 14 is rotatably connected to the connecting shaft 13. The reinforcing ribs 15 are equidistantly arranged on the upper and lower sides of the baffle 14. The reinforcing plate 16 is fixedly fixed to the inside of the baffle 14 by welding. The connecting block 17 is equidistantly installed on the left and right ends of the bottom front of the baffle 14 with the center of the baffle 14 as the reference. The left and right sides of the two ends of the transmission rod 18 are provided with cylindrical protrusions. The transmission rod 18 is rotatably connected to the upper connecting block 17 and the bottom transmission frame 19. The bottom end of the hydraulic cylinder 111 is fixedly connected to the bottom surface of the diversion chamber 1.

[0028] Specifically, the hydraulic cylinder 111 is model JYG70 / 50. The diversion chamber 1 facilitates the upward movement of gas between the baffles 14. The distance between the connecting shafts 13 is limited by the limit bracket 12 to ensure that the spacing between the baffles 14 remains consistent. Since the baffles 14 and the connecting shafts 13 form a rotatable connection, the gas flow rate is limited by adjusting the rotation angle of the baffles 14. The reinforcing ribs 15 and the reinforcing plates 16 increase the rigidity of the baffles 14. The transmission rod 18 is connected to the baffles 14 by the connecting block 17. The bottom end of the transmission frame 19 is rotatably connected to the transmission frame 19. The transmission frame 19 is fixedly connected to the movable end of the hydraulic cylinder 111 via the support block 110. During the extension and retraction of the hydraulic cylinder 111, the transmission frame 19 will move up and down, thereby adjusting the opening and closing angle of the baffle 14 via the transmission rod 18. The transmission rod 18 will tilt during the adjustment of the opening and closing angle of the baffle 14 to accommodate the situation where the connecting block 17 moves during the rotation of the baffle 14, causing the position between the connecting block 17 and the hydraulic cylinder 111 to change.

[0029] In use, the thickness of the baffle 14 is increased by opening a hole in the center of the baffle 14, so that the reinforcing plate 16 can be fixed to the inside of the baffle 14 by welding. At the same time, the reinforcing ribs 15 are equidistantly arranged above the baffle 14 with the center of the baffle 14 as the reference. When the fan blows air into the diversion chamber 1, the force generated by the air pressure difference will be transmitted to the internal reinforcing plate 16 and the upper reinforcing ribs 15, thereby increasing the rigidity of the baffle 14 and preventing the baffle 14 from deforming under the action of air pressure difference, causing the baffle 14 to bend upward and affecting the control of gas flow. The transmission rod 18 is connected to the baffle 14 by the connecting block 17. Next, since the bottom end of the transmission rod 18 is rotatably connected to the transmission frame 19, and the transmission frame 19 is fixedly connected to the movable end of the hydraulic cylinder 111 through the support block 110, the transmission frame 19 will move up and down during the extension and retraction of the hydraulic cylinder 111, thereby adjusting the opening and closing angle of the baffle 14 through the transmission rod 18. The transmission rod 18 will tilt during the adjustment of the opening and closing angle of the baffle 14, and the baffle 14 is controlled by the corresponding hydraulic cylinder 111 below. By adjusting the extension of a single hydraulic cylinder 111, the opening and closing angle of a single baffle 14 is controlled, so as to achieve the effect of fine adjustment of the air volume of each area.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
