The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. In the present disclosure, the terms "include", "arrange", "disposed" and "disposed" are used to mean open-ended inclusion, and mean that there may be additional elements/components/etc. in addition to the listed elements/components/etc.; the terms "first," "second," and the like are used merely as labels, and are not limiting as to the number or order of their objects; the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention.

Unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are intended to be inclusive and mean, for example, that they may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 is the structure schematic diagram of the dust collecting device of the concentrating mill of the utility model. As shown in fig. 1, in this embodiment, a dust collecting device of a concentrating mill is disclosed, which is applied to the discharge end of a belt conveyor and comprises a dust cage 1, a flexible sleeve 2 and a flexible dust curtain 3. Specifically, the dust collecting cover 1 is a hollow cavity with an open lower end, and the upper end of the dust collecting cover is provided with a dust collecting hole which is fixedly connected with the lower end of the reducing head 4, and the upper end of the reducing head 4 is fixedly connected with the dust remover pipeline 5. In this embodiment, the diameter of the dust catcher tube 5 is smaller than the diameter of the dust suction opening, so that the communication between the dust catcher tube 5 and the dust cage 1 is achieved via the reducer 4. Therefore, the cross-sectional dimension of the lower port of the reducer head 4 is larger than that of the upper port thereof.

In addition, in this embodiment, the dust cage 1 has a rectangular cross section, and a mounting hole is opened in one side wall thereof, through which the discharge end of the belt conveyor 6 penetrates into the dust cage 1. The flexible sleeve 2 is a cylindrical structure made of flexible materials, the upper end of the flexible sleeve is fixedly connected to the lower end of the dust collection cover 1, and the lower end of the flexible sleeve is arranged in a material collection bin for storing mineral materials transported by the belt conveyor 6. The effect is that when mineral aggregate falls into the aggregate bin from the discharge end of the belt conveyor 6, the generated raised dust cannot leak, only exists in a cavity formed by the dust collection cover 1 and the flexible sleeve 2, and is then sucked and processed by the dust remover, so that the working environment is improved.

In addition, because the discharge end of the belt conveyor 6 is arranged in the mounting hole in a penetrating manner and mineral aggregate needs to be conveyed, a larger gap exists between the mounting hole and the belt conveyor 6. In order to prevent the dust from leaking out, a flexible dust curtain 3 is arranged between the gaps. The flexible dustproof curtain 3 is also made of flexible materials, one end of the flexible dustproof curtain is fixedly connected to the hole wall of the mounting hole, the other end of the flexible dustproof curtain abuts against the belt conveyer 6, and the flexible dustproof curtain can swing to one side of the discharge end along with the belt conveyer 6 when the belt conveyer 6 runs, so that the transportation operation of mineral aggregate is not influenced, and meanwhile, the dust in the dust collection cover 1 can be prevented from leaking out through the mounting hole. In addition, when the dust collector sucks the raised dust in the dust collection cover 1, negative pressure is generated in the dust collection cover 1, and the flexible dustproof curtain 3 can also play a role in air intake, so that the air pressure in the dust collection cover 1 is prevented from being too low.

Specifically, the flexible dustproof curtain 3 can be composed of a plurality of rubber door curtains, one end of the flexible dustproof curtain is fixed on the inner wall of the mounting hole, and the other end of the flexible dustproof curtain is abutted against the belt conveyor 6 and can swing along with the belt conveyor; in addition, the flexible dustproof curtain 3 can also be composed of a brush, the width of the brush along the length direction of the belt conveyer 6 is not less than 5cm, one end of the brush is fixedly connected to the inner wall of the mounting hole, and the other end of the brush abuts against the belt conveyer 6 and can swing along with the belt conveyer. The flexible dustproof curtains 3 with the two structural forms can play the functions of ventilating and preventing the dust from leaking.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
