Description

Technical Field

[0001] This utility model relates to the field of cooling machine mechanical technology, specifically a rapid hollow shaft cooling device. Background Technology

[0002] A grate cooler is a device used to cool high-temperature clinker. It utilizes a fan and water pump to circulate a cooling medium (usually water or an aqueous glycol solution) across a radiator, reducing the temperature through heat exchange between the water and air. A hollow shaft is a common shaft structure used in mechanical equipment; its interior is empty. It offers advantages such as reduced weight, increased structural strength, and reduced load on the outer casing material.

[0003] The existing Chinese utility model patent with publication number CN209512530U discloses a cooling device for a hollow shaft of a centrally located roller crusher in a grate cooler. The device includes a body, a drive motor mounted at the front end of the body, and a combined reducer connected to the bottom end of the drive motor via a connecting shaft. The output end of the combined reducer is connected to a transmission shaft via a coupling. An exhaust port is provided inside the body. A roller crusher housing is mounted at the bottom of the body, and a roller is mounted at the upper end of the roller crusher housing. The interior of the body is connected to a driven shaft via a multi-threaded hollow shaft. An air inlet is provided at one end of the body. A roller crusher housing seal is provided at the hinge point between the roller crusher housing and the multi-threaded hollow shaft. A baffle is installed on one side of the roller crusher housing. The multi-threaded hollow shaft is fixed to the driven shaft via a slot. This utility model uses an internal multi-threaded spiral structure for the hollow shaft, allowing direct exhaust of cooling air, increasing the heat exchange area by more than 140%, and increasing structural strength by 30%, resulting in better cooling performance.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, the hollow shaft cooling device is a specially designed cooling device, mainly used to reduce the working temperature of the hollow shaft of the central roller crusher. Traditional cooling devices have poor cooling effects, which prevents the internal temperature of the hollow shaft from being reduced quickly, affecting the subsequent use of the hollow shaft. The existence of these problems affects the use of the device. Utility Model Content
