Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the diameter of the air supply hole of the disc groove is small, which easily causes the blockage of the air hole; the single-layer air chamber causes obvious vortex phenomenon, which affects the operation stability of the whole system

Embodiment Construction

[0027] The present invention will be further described in conjunction with accompanying drawings.

[0028] A double air chamber box for suspended material transfer, such as figure 2 As shown, it includes: an air chamber box 2, an airflow partition 5, a disc groove 9, a first arc body 10, a second arc body 13, a protective cover 11, and a rubber sealing tape 12.

[0029] First and second arc-shaped bodies 10, 13 are welded on both sides of the concave arc surface of the disc groove 9, forming a combination of the disc groove and the arc-shaped body; a disc groove air gap 8 is opened in the middle of the disc groove 9, such as Figure 7 , 8 , as shown in 9.

[0030] Compared with the air hole opening of the disc groove in the traditional material conveying system, the pan groove air slot 8 generates less eddy current and has less impact on the air cushion layer. The width of the slot air slot 8 on the disc slot 9 is twice the diameter of the through hole on the existing disc...

Abstract

The invention discloses a double-air-chamber box body for transmitting suspended materials, and relates to a transmission system for long-distance materials transmission. The problem of low running stability of a material transmission system is solved. According to the double-air-chamber box body, a first cambered body (10) and a second cambered body (13) are welded on two sides of a concave cambered surface of a disk slot (9) to form a combined body of the disk slot and the cambered bodies; a disk slot air gap (8) is formed in the middle of the disk slot (9); a rubber seal belt (2) is paved on the end face of an upper opening of an air chamber box (2); the combined body of the cambered bodies is arranged on the rubber seal belt (2); an air flow partition plate (5) is welded in the air chamber body, and divides the air chamber box into an upper small air chamber (6) and a lower large air chamber (3) which have different volumes; an air inlet (1) is formed in a side wall of the air chamber box; reinforcement ribs (7) are uniformly distributed on two side walls of the air chamber box; and an air flow partition plate air gap (4) is formed in the middle of the air flow partition plate (5). A plurality of double-air-chamber box bodies are connected in series with one another; and the conveyer belts are paved on the upper surface of the combined body of the disk slot and the cambered bodies, so that the material transmission system is formed.

Description

technical field [0001] The invention relates to a transmission system for transporting materials over a long distance, which is suitable for transporting coal and other materials in large coal mines. Background technique [0002] The disc groove structure of the existing air-film type suspension material transmission system is an open structure. After the airflow is ejected from the air hole, it flows out from both sides of the conveyor belt. The gas pressure drops to zero at the edge of the conveyor belt. Here the gas The energy loss is the largest, so the fan is used less efficiently. A row of small-diameter through-holes are evenly distributed on the disk grooves in the existing material transmission system, which are easily blocked by dust, causing the air cushion layer to be unstable and the transmission belt to fail to operate normally. The air box of the traditional material conveying system is a single layer, which will cause the vortex phenomenon of the air flow, r...
