Problems solved by technology

[0003] Based on above-mentioned inventor's discovery, existing a kind of screw feeder for steel preparation mainly has the following deficiencies, for example: when iron ore is fed through screw feeder through pulverization, screw rod rotates with iron ore Stone friction will produce a large amount of mineral debris. Since the volume of mineral debris is smaller than the gap between the screw rod and the pipeline, the mineral debris will be concentrated at the bottom of the pipeline under the influence of its own gravity, resulting in iron ore entering the pipeline through the feed port. Blockage by ore cuttings, causing interruption of iron ore feeding

Embodiment 1

[0028] Example 1: Please refer to Figure 1-Figure 6 , the specific embodiments of the present invention are as follows:

[0029] Its structure includes a main body 1, a supporting foot 2, and a feeding box 3. The bottom end of the main body 1 is provided with a supporting foot 2, and the feeding box 3 is located at the front end of the main body 1. The main body 1 includes a feeding pipe 11, Discharge pipe 12, threaded rod 13, feed port 14, chip storage block 15, the top rear end of the feed pipe 11 is provided with a discharge pipe 12, and the threaded rod 13 is installed inside the feed pipe 11, The material opening 14 is located at the connection between the feeding box 3 and the feeding pipe 11 , and the chip storage block 15 is engaged with the bottom end of the feeding pipe 11 .

[0030] The threaded rod 13 includes a threaded body 131, a material guiding device 132, and a screening device 133. The threaded body 131 is arranged inside the feeding pipe 11, and the descr...

Embodiment 2

[0035] Example 2: Please refer to Figure 7-Figure 9 , the specific embodiments of the present invention are as follows:

[0036] The screening material device 133 includes a connecting rod c1, a supporting rod c2, a fixed frame c3, an engaging groove c4, and a filter material plate c5. The connecting rod c1 is embedded in the bottom end of the material guide device 132, and the supporting rod c2 There are four, arranged around the side end of the connecting rod c1, the inner side of the fixed frame c3 is connected with the end of the support rod c2, the engaging groove c4 is located outside the fixed frame c3, the filter material The plate c5 is engaged between two support rods c2, and the engaging groove c4 is engaged with the bottom end of the feed pipe 11, which is beneficial to connect with the bottom end of the material guide device 132 through the connecting rod c1, thereby driving The sieving device 133 rotates, so that the mineral debris placed on the end face of the...

Abstract

The invention discloses a screw feeder for steel preparation. The spiral feeder structurally comprises a main body, supporting legs and a feeding box, wherein the supporting legs are arranged at the bottom end of the main body, the feeding box is located at the front end of the main body, the main body comprises a feeding pipe, a discharging pipe, a threaded rod, a material passing opening and a scrap storage block, the threaded rod comprises a threaded body, a material guiding device and a material screening device, the material guiding device comprises a bottom plate, a frame, a partition plate and material filtering holes, the partition plate comprises a plate body, a rebounding groove, a rebounding piece and an elastic strip, and the rebounding groove comprises a concave groove, an elastic plate, a supporting strip and a cavity. The partition plate is utilized to rotate along with the material guiding device, so that iron ore with large size is driven to move upwards for feeding; and the small-size ore scraps can fall into the scrap storage block from the material filtering holes to be concentrated, all the ore scraps at the bottom end of the feeding pipe can be discharged, and the situation that the ore scraps block the iron ore material is avoided.

Description

technical field [0001] The invention relates to the technical field of steel preparation, in particular to a screw feeder for steel preparation. Background technique [0002] The screw feeder is reliable in the production process of the enterprise. It is especially suitable for continuous batching of materials in the building materials, metallurgy, electric power, chemical industry and other industries. It can effectively help the enterprise improve the production efficiency. In the process of steel preparation, it needs The iron ore is transported to the high-temperature furnace for melting, so the iron ore needs to be transported through the screw feeder to reduce the working intensity of the staff. [0003] Based on above-mentioned inventor's discovery, existing a kind of screw feeder for steel preparation mainly has the following deficiencies, for example: when iron ore is fed through screw feeder through pulverization, screw rod rotates with iron ore Stone friction wil...
