Description

Technical Field

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

[0002] The clinker fired from the rotary kiln is cooled by a grate cooler before being crushed. In the early stage, hammer crushers were generally used because of the loud crushing noise, severe wear and leakage of the crusher. In recent years, new roller crushers have gradually replaced hammer crushers. When the clinker temperature remains normal, roller crushers do have stronger comprehensive applicability, no crushing noise, and no shell leakage.

[0003] Chinese utility model patent: Announcement number CN214234258U discloses a power base, one side of the power base is provided with a mounting base, and a roller crushing shaft is installed on the inner side of the power base and the mounting base, a shaft sleeve is provided at the connection between the roller crushing shaft and the shaft sleeve, a centrifugal fan is provided on the other side of the power base, and the output end of the centrifugal fan is connected with a D tube, one side of the D tube is connected with a D tube, and the other side of the D tube is connected with a No. 2 D tube, a wall panel is fixed to the top of the power base and the mounting base, and one end of the wall panel is located on the outer wall of the No. 2 D tube and a cooling pipe is provided, a nozzle is installed at the bottom end of the No. 2 D tube, a connecting pipe is connected to the bottom of the roller crushing shaft, and an air outlet is opened on one side of the power base, and a scraper is provided on the outer wall of the roller crushing shaft.

[0004] In the prior art, when CN214234258U is in use, a centrifugal fan, a D150 tube, a D100 tube, a No. 2 D100 tube, a cooling tube, a nozzle, a connecting tube and an air outlet are arranged. When the roller crushing shaft is started, the centrifugal fan is started, and the output end of the centrifugal fan outputs cold air through the D150 tube to the D100 tube and the No. 2 D100 tube on both sides. The D100 tube extends into the power seat to cool the shaft sleeve to avoid lubrication failure of the shaft sleeve, thereby causing damage. The No. 2 D100 tube further cools the cold air through the cooling tube wrapped by the outer wall, and then sprays it to the end face of the roller crushing shaft through the nozzle. Since the nozzle is a duckbill type, so the wind pressure sprayed by the nozzle is stronger and the wind speed is faster, so that the air output per unit time is the highest, and the end surface of the roller crusher shaft is quickly cooled down, which effectively solves the problem that the roller crusher shaft lacks a cooling device, resulting in the roller crusher shaft being at high temperature for a long time and being easy to be damaged; by arranging a scraper and a fixing rod, the scraper is fixed to the power seat and the mounting seat by the fixing rod. Since the inner wall of the scraper fits with the outer wall of the roller crusher shaft, when the roller crusher shaft crushes the material, the material residue remaining on the outer wall of the roller crusher shaft will fall off due to the friction between the scraper and the roller crusher shaft when it rotates to contact the scraper, which effectively solves the problem of cross contamination of materials and waste of resources.

[0005] However, in actual operation, the temperature of the roller crusher shaft increases very quickly when it rotates for a long time. If the roller crusher shaft cannot be cooled quickly, the service life of the roller crusher shaft will be reduced. Therefore, a roller crusher clinker rapid cooling device is needed to solve the above problem. Utility Model Content

[0013] Preferably, the number of the rib teeth is eighteen, and the size of the rib teeth is smaller than the size of the tooth grooves.

[0014] By setting the tooth size to be smaller than the tooth groove size, a gap can be left between the tooth and the tooth groove, and the gap between the tooth and the tooth groove can be used for the circulation of coolant, thereby quickly cooling the roller sleeve body and the broken roller shaft body through the coolant.

[0015] Preferably, the tooth grooves are arranged in a ring array on the inner side of the roller sleeve body, and the number of the tooth grooves is eighteen.

[0016] By arranging the teeth and grooves on the inner side of the roller sleeve body, the broken roller shaft body can be positioned and installed on the inner side of the roller sleeve body through the fit between the ridge teeth and the teeth and grooves during use.

[0017] Preferably, the diameter of the roller sleeve body matches the diameter of the sealing shell, and sliding grooves are provided at both ends of the roller sleeve body.

[0018] By matching the diameter of the roller sleeve body with the diameter of the sealing shell, the outer wall of the roller sleeve body and the outer wall of the sealing shell can be located in the same plane during use.

[0019] Preferably, the movable card in the limit slot is equipped with a limit card, and the limit card is designed with carbon steel material.

At this time, the sealing shell is sleeved on both ends of the broken roller shaft body, and the limiting card is clamped in the limiting groove of the broken roller shaft body, so as to realize the operation of movably installing the sealing shell on the broken roller shaft body. At the same time, the sealing shell is slidably installed in the slide groove, so that when the broken roller shaft body rotates, the sealing shell will not rotate synchronously. When the roller crushing operation is carried out for a long time, a coolant circulation mechanism can be installed at the end of the connecting pipe away from the sealing shell, so that the coolant can circulate on the opposite side of the roller sleeve body and the broken roller shaft body, thereby achieving the effect of quickly cooling the roller crushing shaft.
