Embodiment 1

[0043]The roller crusher high temperature blocking system provided by the present invention includes a cooling air chamber 1, a fan 2 is connected to the cooling air chamber 1, and the cooling air chamber 1 is arranged on the shell 3 of the roller crusher, and The cooling air chamber 1 is arranged coaxially with the roller shaft 4 of the roller crusher,

[0044] A ventilation gap 5 is formed between the roller shaft 4 of the roller crusher and the housing 3 of the roller crusher, the cooling air chamber 1 communicates with the ventilation gap 5, and the cold air of the fan 2 passes through the cooling air. The chamber 1 enters the roller chamber crusher from said ventilation gap 5 in order to reduce the temperature of the roller shaft 4 of the roller chamber crusher.

[0045] Specifically, the cooling air chamber 1 includes an air chamber body 11. The air chamber body 11 is a cylindrical structure with an opening on one side, and the side is sealed with the shell 3 of the roll...

Embodiment 2

[0048] The difference between this embodiment 2 and embodiment 1 is that the cooling air chamber 1 has a ring structure, and the cooling air chamber 1 of the ring structure is set on the roller shaft 4 of the roller chamber crusher, and is connected with the roller chamber crusher. The shell 3 of the roller chamber crusher is connected, and an air outlet 13 is provided on the side where the cooling air chamber 1 is in contact with the shell 3 of the roller chamber crusher, and the air outlet 13 communicates with the ventilation gap 5 .

Abstract

The invention provides a high-temperature blocking system of a roller crusher, and relates to the technical field of crushers. The technical problem that the temperature of a high-temperature material in the roller crusher in the prior art is conducted to a bearing or a speed reducer, so that the speed reducer or the bearing breaks down is solved. The high-temperature blocking system of the roller crusher comprises a cooling air chamber, a fan is connected to the cooling air chamber, the cooling air chamber is arranged on a shell of the roller crusher, the cooling air chamber and a roller shaft of the roller crusher are coaxially arranged, a ventilation gap is formed between the roller shaft of the roller crusher and the shell of the roller crusher, the cooling air chamber communicates with the ventilation gap, and cold air of the fan passes through the cooling air chamber and enters the roller crusher from the ventilation gap, so that the temperature of the roller shaft of the roller crusher is reduced. The high-temperature blocking system of the roll crusher can effectively block the roll shaft of the crusher from conducting high temperature to the bearing and the speed reducer.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a high temperature blocking system of a roller crusher. Background technique [0002] In the cement kiln system, the roller crusher installed at the outlet of the grate cooler is the equipment responsible for crushing the cooled clinker. If there is a problem with this equipment, it will directly affect the normal operation of the cement kiln. Due to the particularity of its operating environment, the temperature of the cooled clinker is still high, and the temperature of the high-temperature clinker is transmitted to the support bearing through the rollers, which even causes the temperature of the reducer to rise and cannot operate normally. [0003] The applicant found that the prior art has at least the following technical problems: the temperature of the high-temperature material in the existing roller crusher will be transmitted to the bearing or the reducer, thus causing t...
