Example Embodiment

[0013] The present invention will be further described below in conjunction with the examples, but it is not intended to limit the present invention.

[0014] See figure 1 , figure 2 , the pressureless water-cooled grid beam of the ring cooler includes the support 2, the screen beam 3 and the beam 4 located in the kiln head cover 1, and also includes the water inlet pipe 5 and the water outlet pipe 6, and the screen beam 3 and the beam 4 are at least equipped with Two screen caps, the device is a water-cooled grid beam device, which takes away heat through water flow to achieve cooling effect. The two ends of the beam 4 of the device are arranged on the support 2, the beam 4 and the screen beam 3 are both hollow beams with one end closed, the closed end 31 of the screen beam 3 is arranged on the beam 4, and the other end 32 is arranged on the support 2. , forming a tilted state where one head is high and the other is low. The structure of hollow beam is as image 3 Said, ...

Abstract

The invention discloses an annular-cooler non-pressure water-cooling grating beam which comprises supporting bases, screening beams and a cross beam, wherein the supporting bases, the screening beams and the cross beam are located in a kiln head cover. The annular-cooler non-pressure water-cooling grating beam further comprises a water inlet pipe and a water outlet pipe, the two ends of the cross beam are installed on the supporting bases, the cross beam and the screening beams are all hollow beams with one sealed ends, the sealed ends of the screening beams are installed on the cross beam, and the other ends of the screening beams are installed on one supporting base. The interior of each hollow beam is divided into an upper water chamber and a lower water chamber through a supporting and partitioning plate, each upper water chamber is communicated with each lower water chamber at the sealed end of each hollow beam, the open ends of the upper water chambers are communicated with the water inlet pipe, and the open ends of the lower water chambers are communicated with the water outlet pipe. According to the annular-cooler non-pressure water-cooling grating beam, frequent changes of temperature are prevented from leading to strength reduction of the hollow beams, effective cooling is achieved to maintain strength of the cross beam and the screening beams, and service life is prolonged.

Description

technical field [0001] The invention relates to a grid beam of a ring cooler, in particular to a pressureless water-cooled grid beam of a ring cooler, which is suitable for the technical fields of metallurgy and chemical engineering. Background technique [0002] The ring cooler is an important thermal equipment in the process of pellet cooling and consolidation on the grate machine-rotary kiln production line. Its main function is to air-cool the oxidized pellets roasted at high temperature in the machine to remove heat. The grid beam is located at the feeding place of the ring cooler, which is used to slow down the falling speed of the pellets, and filter the high-temperature pellets with too large volume to avoid excessive impact on the rotating trolley and damage the equipment. After the high-temperature pellets are roasted, the temperature can usually reach It can reach above 1200°C. Therefore, under the continuous working state of the ring cooler, the grid beam must ha...
