Technical Field

[0001] The utility model belongs to the technical field related to material screening, and particularly relates to a heat-resistant flip grate plate. Background Art

[0002] Grate cooler is a quenching cooler. After the clinker enters the cooler from the kiln, it forms a layer of material with a certain thickness on the grate plate. The cold air blown in passes through the material layer moving on the grate bed in a perpendicular direction to cool the clinker rapidly. The clinker can be cooled from 1300-1400℃ to below 100℃ in a few minutes. Grate cooler is a quenching cooler. After the clinker enters the cooler from the kiln, it forms a layer of material with a certain thickness on the grate plate. The cold air blown in passes through the material layer moving on the grate bed in a perpendicular direction to cool the clinker rapidly. The grate plate is a commonly used device in grate cooler production, especially in cement production. It is the core component of the grate cooler and is mainly used for cooling and conveying clinker. The design and performance of the grate plate directly affect the working efficiency of the grate cooler and the cooling effect of the clinker. However, it still has the following disadvantages in actual use:

[0003] When the grate plate is working, it directly supports the material. However, during the grate plate operation, the material is directly supported on it and the cooled material is screened out by vibration. However, after screening out, the operator needs to clean the remaining material impurities on it, which is not convenient to operate during the working process.

[0004] When the grate plate is working, in order to transport the material, the material needs to be supported in a suitable position and vibrated by the exciter under the drive of the motor. However, during the vibration process, the heat on the material is directly transferred to the motor, causing the motor to overheat and shut down, affecting the use of the motor.

By arranging a movable frame, a support assembly, a heat-resistant grate plate body, a support bar and a heat insulation cover, the problem that it is inconvenient to clean the retained impurities when the grate plate is working and the motor is prone to overheating and shutting down when working is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a heat-resistant flip grate plate, comprising a movable frame, a support assembly, a heat-resistant grate plate body, a support bar and a heat insulation cover, wherein the heat-resistant grate plate body is provided on the top of the movable frame, three equidistant lifting rings are fixed at a short side of the top of the heat-resistant grate plate body, a connecting shaft is fixed on one end of the heat-resistant grate plate body away from the lifting ring, a guide plate is fixed on the circumferential side of the connecting shaft at a position symmetrical to the heat-resistant grate plate body, a support bar is provided below the connecting shaft, a heat insulation cover is provided on one side of the heat-resistant grate plate body, one end of the heat insulation cover is fixedly connected to an air inlet duct, and an opening is provided on the side of the heat insulation cover close to the heat-resistant grate plate body. A driving motor and two vibrators are provided in the heat insulation cover, and support assemblies are fixed to the bottom of the driving motor and the two vibrators, and the support assemblies at the bottom of the driving motor and the two vibrators are fixed to the inner bottom of the heat insulation cover. Three equidistant support assemblies are fixed to the lower parts of both sides of the movable frame, and support assemblies are fixed to the two short sides of the bottom of the support bar. When working, the heat-resistant grate plate body is supported on it by the movable frame, and when it vibrates, it drives the heat-resistant grate plate body to vibrate. The movable frame and the support bar are supported on the external support structure by the support assembly, and the driving motor and the two vibrators in the heat insulation cover are supported therein.

[0008] Furthermore, the support assembly includes a fixed platform, a vibration-damping spring and a fixed block. A vibration-damping spring is fixed to the top center of the fixed platform, and a fixed block is fixed to the top of the vibration-damping spring. When the support assembly is working, it is fixed to the supporting structure through the fixed platform and vibration is reduced by the vibration-damping spring.

[0009] Furthermore, an external fixed frame is fixed to the top of the heat-resistant grate plate body between the connecting shaft and the lifting ring, and movable openings are evenly opened in the heat-resistant grate plate body within the external fixed frame.

[0011] Furthermore, a rotating shaft is fixed to the output end of the driving motor, an end of the rotating shaft away from the driving motor is fixed to the input end of an exciter, a transmission shaft is fixed to the output end of the exciter close to the driving motor, an end of the transmission shaft away from the driving motor is fixed to the input end of the exciter away from the driving motor. When the driving motor is working, it drives the exciter to work by driving the rotating shaft to rotate, and drives the transmission shaft to drive another exciter to work, so that when working, the two exciters work synchronously.

[0012] Furthermore, a connecting plate is fixed to the lower part of one side of the two vibrators close to the movable frame, and the connecting plate is movably arranged in the opening. One end of the two connecting plates away from the vibrator is fixed to the side of the movable frame close to the heat insulation cover. When the vibrator is working, the vibration is transmitted to the movable frame through the connecting plate.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that it is inconvenient to clean the retained impurities when the grate plate is working by arranging the movable frame, the supporting assembly, the heat-resistant grate plate main body and the supporting bars. The materials are placed on the external fixed frame and supported by the heat-resistant grate plate main body, and driven by the vibrator to drive the heat-resistant grate plate main body to vibrate. During the vibration, the materials on the heat-resistant grate plate main body are screened through the movable opening and fall into the movable frame, and then fall into the collecting device below it through the movable frame. When a certain amount of screened materials remain in the external fixed frame, the materials are hooked to the lifting ring through the lifting hook of the factory area lifting equipment, and then the lifting equipment is started. The lifting equipment pulls the heat-resistant grate plate main body, so that the materials on the heat-resistant grate plate main body are dumped and output through the material guide plate, and then the heat-resistant grate plate main body is put back to its original position by the lifting equipment, and the hook is separated from the lifting ring to complete the work, making it more convenient to clean the retained impurities when the grate plate is working.

[0015] The utility model solves the problem that the motor is prone to overheating and shutting down when the grate plate is working by arranging a movable frame and a heat insulation cover. When the driving motor is working, the driving shaft rotates to drive the vibrator to work. The power is transmitted between the two vibrators through the transmission shaft. In the process of the vibrator working, the connecting plate is driven to vibrate. When the connecting plate vibrates, the movable frame and the fixed block are driven to vibrate. While the driving motor is working, the external air conveying equipment is started, and the air is conveyed to the air inlet duct through the external air conveying equipment, and then to the heat insulation cover through the air inlet duct, so as to dissipate the heat of the driving motor. After the heat is dissipated, the air is discharged through the opening. During operation, the heat insulation cover blocks heat radiation and actively cools the air, which effectively prevents the motor from overheating and shutting down when the grate plate is working, thereby increasing the smoothness of the work.

An opening 501 is provided on the side of the heat insulation cover 5 close to the heat-resistant grate plate body 3, and the air in the movable frame 1 is discharged through the opening 501. A drive motor 503 and two vibrators 505 are provided in the heat insulation cover 5. The vibrators 505 are driven by the driven motor 503.
