Embodiment Construction

[0010] See accompanying drawing, the present invention has a rectangular beam 1, is constructed with a triangular beam 2 on the top of rectangular beam 1, and the upper wing plate 21 of rectangular beam 1 extends widening to both sides, uses it as the base of upper triangular beam 2, in Rectangular holes 24 are opened on the hypotenuse steel plate 23 of the two waists of the triangular beam 2, and the grate bar 25 is welded into a fixed grate plate with round steel in the rectangular hole 24, and ventilation holes are arranged on the edge extension of the upper wing plate 21 of the rectangular beam 1 22. The side plate 11 of the rectangular beam 1 is used as an integral part of the static seal of the trolley.

[0011] When the structure of the present invention is working, the cold wind enters the material layer A area from under the trolley grate plate through the grate plate 3 according to the front direction, and also enters the abdomen of the triangular beam 2 through the v...

Abstract

The present invention discloses a bearing beam structure for a circular cooling trolley. The present invention is based on a rectangular beam, and a triangle beam is designed at the upper part of the rectangular beam, the upper plate of the rectangular beam is extended and broadened to the both sides to form an upper cross section which is a bottom edge of the triangle beam, a plurality of ventilation channels are arranged on the bevel edge steel plates at the both waists, an air ventilating channel is arranged on the bottom edge of the triangle beam, and the side plate of the rectangular beam is a component element of the trolley static seal. The present invention is used on a water seal circular cooling machine, has the main structure character that the trolley loading is supported by the rectangular beam, the triangle beam is used to discharge and guide, through ventilating with the air ventilating channel of three edges of the triangle beam, cold air under the grid plate of the trolley can be led to the both sides and upper material layers of the triangle beam, not only the cooling dead zone is eliminated, but also the total ventilating area of the trolley can be increased about 16 percent. As a component element of the trolley static seal, the side plate of the rectangular beam can prefect the sealing of the bearing beam structure bottom part and the trolley.

Description

technical field [0001] The invention belongs to a blast ring cooler used for cooling sintered pellets in the metallurgical and mining industry, and in particular relates to a supporting beam structure of a trolley of the ring cooler. Background technique [0002] The supporting beam of the trolley of the existing annular cooler is a beam with a triangular cross section, and the three sides of the beam are all blind plates, which only play the role of supporting the trolley. When working, the trolley grate plate and the inclined surface of the triangular beam are filled with mineral materials, and the cold air is forced to blow into the material layer from under the trolley grate plate for heat exchange. Because the wind always follows the area with the least resistance and the shortest distance Passing through both sides of the beam, after exchanging heat with the mineral material, it is discharged into the atmosphere from the top surface of the material layer. Since the tri...
