Referring to fig. 1 to 5, a blanking funnel with a dustproof structure according to an embodiment of the present invention includes: the funnel body 100, the first bracket ring 200, the second bracket ring 300, the support rod 400, the tapered plate 500. The funnel body 100 is a vertically arranged inverted cone, the inner wall has a conical surface, the funnel body 100 can be directly fixed with the ground or can be installed on other material containers, the first support ring 200 is horizontally embedded into the funnel body 100 and attached to the conical surface, the second support ring 300 is horizontally embedded into the funnel body 100 and attached to the conical surface, the diameter of the second support ring 300 is larger than that of the first support ring 200, the support rod 400 is used for connecting the first support ring 200 and the second support ring 300, the length of the support rod 400 is matched with the sizes of the first support ring 200 and the second support ring 300, so that the first support ring 200 and the second support ring 300 can be abutted to the funnel body 100, and the funnel body 100 can be installed by only placing the first support ring 200 and the second support ring 300 into the funnel body 100, the installation is completed and the tapered plate 500 is connected to the upper end of the support rod 400 and is located in the funnel body 100. The conical plate 500 is disposed coaxially with the funnel body 100. The diameter of the bottom end of the conical plate 500 is smaller than that of the second support ring 300, the support rod 400 is welded on the first support ring 200 and the conical plate 500, the connecting rod 310 is welded on the inner side of the second support ring 300, the connecting rod 310 is welded on the support rod 400, when materials move at a certain speed in the air, the materials can drive the surrounding air to flow together with the materials, the air is called induced air, the induced air can suck a part of dust in a rolling mode, the air flows together, the falling speed of the materials is higher, the induced airflow is higher, and the sucked dust is more. After the material falls to conical plate 500 in funnel body 100, conical plate 500 can effectual reduction material falling speed to the material water conservancy diversion to reduce the production of dust.

According to the blanking funnel with the dustproof structure, the first support ring 200 and the second support ring 300 are abutted against the funnel body 100, the conical plate 500 is fixed with the first support ring 200 and the second support ring 300 through the support rod 400, after a material in the funnel body 100 falls to the conical plate 500, the conical plate 500 guides the material, the falling speed of the material can be effectively reduced, and therefore the generation of dust is reduced. Utilize self shape spacing, simple structure need not to install complicated electric system, and investment and working costs are few, can be fast effectual reform transform current unloading funnel.

In some embodiments of the present invention, the upper end of the funnel body 100 is provided with an upper cover 600, a first inlet pipe 610 for passing the material is centrally arranged through the upper cover 600, and the first inlet pipe 610 is welded in the upper cover 600. When the material falls into the funnel body 100, the material occupies a certain space, so that the air in the funnel body 100 is compressed, and the compressed air must flow outwards through the opening above the funnel body 100, thereby bringing the dust out of the funnel body 100. The upper cover 600 serves to prevent dust from overflowing the funnel body 100.

In some embodiments of the utility model, the first inlet tube 610 has a lower end with a smaller diameter than the upper end of the funnel 100, and the first inlet tube 610 narrows at its lower end. The narrowing of the lower end of the first inlet tube 610 facilitates reducing dust passing through the first inlet tube 610. The smaller the opening at the upper end of the funnel body 100, the less the amount of dust spilled, compared to the funnel body 100 having its upper end directly opened.

In some embodiments of the present invention, the positioning tube 620 is welded at the center of the lower end of the upper cover 600, the positioning tube 620 is embedded into the upper end of the funnel body 100, and when the upper cover 600 is installed, only the positioning tube 620 is embedded into the funnel body 100, so that the connection is firm and the installation is convenient.

In some embodiments of the present invention, the funnel body 100 is welded with the second inlet pipe 110 at the upper end thereof, in which the positioning cylinder 620 is inserted, and the diameter of the second inlet pipe 110 is equal to the diameter of the upper end of the funnel body 100. The upper end of the funnel body 100 is conical, which is not beneficial to the embedding of the positioning cylinder 620, and the diameter of the second inlet pipe 110 is matched with that of the positioning cylinder 620, so that the positioning cylinder 620 can be embedded conveniently.

In some embodiments of the present invention, a sealing ring 621 is sleeved on the positioning cylinder 620, the sealing ring 621 abuts against the second inlet pipe 110, the sealing ring 621 is made of rubber and is fixed on the positioning cylinder 620 by its own elasticity, and after the positioning cylinder 620 is embedded in the second inlet pipe 110, the sealing ring 621 can prevent dust leakage.

In some embodiments of the present invention, the upper cover 600 is a hollow cylinder, a dust outlet 630 communicated to the inside of the upper cover 600 is opened between the positioning cylinder 620 and the first inlet pipe 610, and since the area of the dust outlet 630 is much larger than that of the first inlet pipe 610, most of the dust carried in the air enters the inside of the upper cover 600 through the dust outlet 630.

In some embodiments of the present invention, the side wall of the upper cover 600 is provided with a filter screen 640, and the filter screen 640 is used for filtering dust in air, and the air and the dust pass through the filter screen 640 on the side wall of the upper cover 600 after entering the interior of the upper cover 600, so as to filter the dust.
