Problems solved by technology

[0004] In order to solve the problem of air pollution caused by the leakage of powder in the material and the energy consumption of the cooling fan caused by the application of the cooling device in the prior art, the present invention provides a cooling device for an annular cooler, the cooling device uses air in whole or in part. As a cold air source, energy saving, and at the same time, the external pressure of the annular cooler is lower than the internal pressure, that is, negative pressure operation, which effectively solves the problem of powder leakage in the material

Embodiment 1

[0041] reference figure 1 with figure 2 , Respectively are the structural schematic diagram and the top view of the annular cooler with cooling device of the present invention. The annular cooler includes a feeding device 1, an annular material channel 2, a discharging device 3 and a cooling device 4. The material enters from the feeding device 1, and is discharged from the discharging device 3 after passing through the annular material channel 2. The cooling device 4 is used for Cool the material in the annular material channel 2.

[0042] The feeding device 1 includes a hollow structure and the top sealed end of the inner cylinder. The upper end of the hollow structure 11 is the upper open end for material entry, the lower end of the hollow structure and the top end of the outer cylinder 22 are along the circumferential direction. Fixed connection. The sealed end of the top of the inner cylinder 21 can be a flat structure; or a conical side surface of a conical structure, whe...

Embodiment 2

[0055] The difference between the second embodiment and the first embodiment is that the sealed suction chamber at the upper part of the outer cylinder 22 is replaced by a sealed air supply chamber. The sealed air supply chamber is an annular closed space covering the ventilation holes of the outer cylinder. The air chamber is provided with an air inlet, which is connected with a cold air source (air cooler). The cold air source enters the annular material passage through the air inlet and the vent on the outer cylinder. The hot air after heat exchange with the material can pass through the upper part of the annular material passage. The opening is returned to the upper level device (for example: rotary kiln) for reuse, the generated dust can also be returned to the upper level device (for example: rotary kiln) with the hot air, and the dust entering the inner cavity of the inner cylinder 21 can be opened from the bottom of the inner lower hopper End 34 is discharged.

Embodiment 3

[0057] The difference between Embodiment 3 and Embodiments 1 and 2 is that for each sealed suction chamber, more than one suction opening can be provided, and each suction opening is connected with a suction fan to draw air from different suction openings. Preferably, for a sealed suction chamber, a plurality of suction openings are evenly distributed along the circumferential direction to ensure uniform cooling of the material. Another preference is that all the air extraction openings of each sealed air extraction chamber are evenly distributed in the circumferential direction, which also ensures uniform cooling of the material.

Abstract

To solve the problems that when cooling devices in the prior art are used, powder in materials leaks to cause air pollution and air coolers consume energy, the invention provides a cooling device for an annular cooling machine. The cooling device comprises one or more sealed air suction chambers which are arranged outside an outer cylinder body, each sealed air suction chamber comprises a side wall, an upper cover and a lower cover, all ventilation holes or the ventilation holes in the lower portion of the outer cylinder body are covered with annular sealed spaces formed by the upper covers, the lower covers, the side walls and the outer cylinder body, the side wall of each sealed air suction chamber is provided with one or more air suction openings, and the air suction openings are used for being communicated with a suction fan in a sealed mode. The whole or part of the cooling device uses air as a cold air source, and energy is saved; meanwhile, the intensity of external pressure of the annular cooling machine is less than the intensity of internal pressure of the annular cooling machine, namely negative pressure operation is conducted, and the problem that the powder in the materials leaks is solved effectively.

Description

Technical field [0001] The invention relates to a material cooling device, in particular to a cooling device for an annular cooling machine and an annular cooling machine adopting the cooling device. Background technique [0002] Cooler is an indispensable important equipment in metallurgy, chemical industry, cement building material calcination system. Its main function is to cool the hot materials to the temperature allowed by the subsequent transportation, storage and grinding processes according to the process requirements to ensure normal continuous production; at the same time, the cooler is also a heat exchange device, which requires The heat content is recovered and utilized to the maximum extent to improve the thermal efficiency of the system. [0003] The cooling method of the existing annular cooler is to blow cold air into the material layer of the annular cooler by a cooling fan, and cool the material through heat exchange between the cold air and the material, and th...
