Description

Technical Field

[0001] The utility model relates to the technical field of cement clinker processing, in particular to a cement clinker cooling device. Background Art

[0002] Cement clinker is the main raw material of cement, which needs to be fired in a clinker kiln and then cooled during the production process. Traditional cement clinker cooling devices usually use grate coolers for cooling. Cement clinker enters the grate cooler entrance and is cooled by cold air during the process of being transported by the conveying device. However, the cooling devices in the prior art still have certain defects when used and need to be improved.

[0003] When the cooling device in the prior art is in use, since cement clinker enters the grate cooler from the discharge port of the rotary kiln for cooling, it falls onto the conveying device after entering and causes stacking. The stacked cement clinker is difficult to be cooled by cold air and cannot be cooled evenly, resulting in reduced cooling efficiency. Therefore, a cement clinker cooling device is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the disadvantage of uneven cooling of cement clinker in the grate cooler in the prior art, and proposes a cement clinker cooling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cement clinker cooling device comprises a grate cooler body, a second motor is installed on the grate cooler body, and a half-tooth gear is installed at the output end of the second motor.

[0007] Two limit frames are installed on the inner wall of the grate cooler body, springs are connected in the two limit frames, one end of the two springs is connected to connecting rods, and the bottom ends of the two connecting rods are connected to the bottom frame.

[0008] Both sides of the bottom frame are connected with a plurality of wedge blocks, and each wedge block is connected with a partition plate.

[0009] A U-shaped frame is installed on the top of the bottom frame, a rack is connected to one side of the U-shaped frame, and the rack is meshed with the half-tooth gear.

[0010] Preferably, a conveying device is provided inside the grate cooler body.

[0011] Preferably, a first motor is installed on one side of the grate cooler body, and a spiral rod is installed on the output end of the first motor.

[0012] Preferably, the end of the conveying device is located on the screw rod.

[0013] Preferably, a sliding frame is installed inside the grate cooler body, and the rack is slidably fitted in the sliding frame.

[0014] Preferably, a plurality of wedge-shaped grooves are formed on the bottom frame, and directions of the plurality of wedge-shaped grooves correspond to the wedge-shaped blocks.

[0015] The utility model has the following beneficial effects:

[0016] 1. With the cooperation of the wedge block and the partition, the cement clinker falls onto the conveying device and is transported to the tail through the conveying device. During the process, the second motor is started to move the wedge block to guide the cement clinker, and the cement clinker is separated by the partition and falls from the tail of the wedge block, so that there are gaps between the cement clinker to supply cold air to cool it evenly and avoid stacking, so that the cement clinker can be cooled more evenly when it is cooled inside the grate cooler, thereby improving the cooling efficiency;

[0017] 2. With the cooperation of the spring and the half-toothed gear, the rack can drive the wedge block to move through the half-toothed gear, and push the wedge block back to its original position through the spring, and push the wedge block and the cement clinker behind the bottom frame away, thereby accelerating the transportation of the cement clinker. After the half-toothed gear rotates one circle, the toothed part of the half-toothed gear continues to mesh with the rack and drives the rack again to move the wedge block, and the reciprocating cycle further increases the efficiency of cooling the cement clinker.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4A cement clinker cooling device comprises a grate cooler body 1, a conveying device 101 is arranged inside the grate cooler body 1, and the conveying device 101 is composed of a drive, a frame, a conveyor belt and other structures, wherein a wedge block 8 is located on the conveying device 101 and contacts the conveyor belt, a first motor 102 is installed on one side of the grate cooler body 1, a screw rod 103 is installed at the output end of the first motor 102, and the discharge of the conveying device 101 is located on the screw rod 103, and the cement clinker enters from the feeding port of the grate cooler body 1 and falls onto the conveying device 101 The cement clinker is transported to the end through the conveying device 101. During the transportation process, the cement clinker is cooled by the cold air. After reaching the end, the first motor 102 is started to drive the screw rod 103 to rotate to crush the cement clinker. A sliding frame 12 is installed inside the grate cooler body 1. The rack 11 slides in the sliding frame 12. The rack 11 slides in the sliding frame 12 to limit the movement of the rack 11 to prevent the rack 11 from shifting. A second motor 2 is installed on the grate cooler body 1, and a half-tooth gear 3 is installed at the output end of the second motor 2.

[0025] Two limit frames 4 are installed on the inner wall of the grate cooler body 1, and springs 5 ​​are connected to the two limit frames 4. One end of the two springs 5 ​​is connected to a connecting rod 6, and the bottom ends of the two connecting rods 6 are connected to a bottom frame 7. The other end of the spring 5 is connected to the inner wall of one side of the limit frame 4, and the top end of the connecting rod 6 slides in the limit frame 4. A plurality of wedge-shaped grooves 701 are opened on the bottom frame 7, and the directions of the plurality of wedge-shaped grooves 701 correspond to the wedge blocks 8. The wedge-shaped grooves 701 are set to facilitate the export of cement clinker between two adjacent wedge blocks 8.

[0026] Both sides of the bottom frame 7 are connected to a plurality of wedge blocks 8, each of which is connected to a partition 9. When the cement clinker is guided onto the wedge blocks 8, the partitions 9 separate the cement clinker, and when the cement clinker is guided to the end of the wedge blocks 8, the gap between the cement clinkers is increased, thereby increasing the cooling effect.

[0027] A U-shaped frame 10 is installed on the top of the bottom frame 7, and a rack 11 is connected to one side of the U-shaped frame 10. The rack 11 is meshed with the half-toothed gear 3. By starting the second motor 2 to drive the half-toothed gear 3 to rotate, the rack 11 moves and drives the wedge block 8 to move. During the movement of the wedge block 8, the conveying device 101 is cooperated to guide the cement clinker and drop it from the end of the wedge block 8. At this time, there are gaps between the cement clinker, and the cold air cools the cement clinker evenly. At this time, the spring 5 is compressed. When the half-toothed gear 3 rotates half a circle, the toothless part of the half-toothed gear 3 contacts the rack 11, so that the spring 5 pushes the connecting rod 6 to push the wedge block 8 back to its original position, and pushes the wedge block 8 away from the cement clinker behind the bottom frame 7, thereby accelerating the transportation of the cement clinker. After the half-toothed gear 3 rotates one circle, the toothed part of the half-toothed gear 3 continues to mesh with the rack 11 and drives the rack 11 again to move the wedge block 8, and the cycle is repeated, so that the cooling efficiency of the cement clinker is accelerated.
