Medium and high temperature roller crusher with high efficiency composite cooling system

Abstract

The invention relates to a medium and high temperature roller crusher with a high efficiency composite cooling system. The medium and high temperature roller crusher with the high efficiency compositecooling system comprises a transmission device, a crushing unit, a miniature heat pipe cooling system, a water cooling system, a driven end sealing system and a measurement and control system, wherein the miniature heat pipe cooling system efficiently dissipates heat to a cavity of a roller through a miniature heat pipe, and symmetric fluid grooves of a micropore accelerate the cooling of the roller; in the water cooling system, a part of high pressure water is sprayed onto the inner wall of the upper part of the cavity of a roller shaft and a condensation section of the heat pipe for heat transfer through a high pressure cooling water spray head, and a part of high pressure water is sprayed out through axial small spray pipes and a radial small spray pipes of an immersion type spray headto generate high-speed jet flow and rotational flow which are in opposite directions, so that accumulated water highly forms turbulence flow; recesses of the inner surface of the roller shaft strengthens the surface heat dissipation; the cooling systems endow the medium and high temperature roller crusher with high efficiency cooling performance; and the driven end sealing system is provided witha reverse thread groove seal, an air cavity seal, and a ring-shaped air bag air seal, so that the good shaft end seal can be realized. The high efficiency cooling sealing characteristic of the mediumand high temperature roller crusher can ensure the safe and reliable operation of the medium and high temperature roller crusher in the medium and high temperature region of a grate cooler.

Description

technical field [0001] The invention belongs to the field of production equipment in the cement industry, in particular to a high-temperature roller crusher with a high-efficiency composite cooling system. Background technique [0002] The grate cooler is an important equipment in the clinker burning system of the new dry process cement decomposition kiln. Power generation from waste heat. In the grate cooler, by installing a clinker crusher to break large pieces of clinker into small pieces of clinker, the cooling speed of clinker can be greatly accelerated, the temperature of clinker discharge can be reduced, and the heat recovery efficiency of the grate cooler can be improved. With the development of large-scale new grate coolers and the further improvement of waste heat recovery efficiency requirements, the hammer crusher as a traditional crushing equipment has been difficult to meet the new production technology requirements, and the roll crusher has good adaptability ...
