Description

Technical Field

[0001] This utility model relates to the field of metallurgical feeding, and in particular to a device for preventing the escape of dusty materials. Background Technology

[0002] Metallurgical materials include ordinary granular materials and powdery materials. During smelting, various materials need to be transported to a mixing device in a certain proportion to be mixed into a homogeneous ore. Different materials are fed into the conveyor trough on the belt conveyor through different silos. When the powdery material silo is conveying the powdery material, whether it is fed first or last, it will scatter on the top layer. During the conveying process, the powdery material is easily blown away and escapes, causing deviations in the amount of powdery material added, deteriorating the working environment, increasing the workload, and even endangering human health. Summary of the Invention

[0003] To address the problem of powdery material scattering during the feeding and conveying process, this utility model provides a device to prevent the scattering of powdery materials. When powdery materials are fed onto ordinary materials, the ordinary materials can be used to bury the powdery materials under them, thus preventing the powdery materials from escaping during the conveying process.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: a device for preventing the dispersion of dusty materials, comprising a conveyor belt, a powdery material hopper, and a feeder, characterized in that: it further comprises a plow head device and a leveling device, the conveyor belt having both sides bent upward to form concave grooves, the powdery material hopper being located above the conveyor belt, the feeder being connected to the powdery material hopper and used to feed the powdery material in the powdery material hopper into the concave grooves of the conveyor belt, one end of the plow head device being connected to the feeder, and the other end extending into the concave groove, the plow head device comprising a pointed end and an open end, and the leveling device being disposed on one side of the open end of the plow head device.

[0005] Specifically, the concave groove is formed by bending the two sides of the conveyor belt upwards using a roller.

[0006] Furthermore, the tip of the plowshare faces upstream of the material flow, and the open end of the plowshare faces downstream of the material flow.

[0007] Furthermore, the leveling device consists of two leveling plates, with one end of the two leveling plates fixedly connected and the other end connected to both sides of the opening end of the plow head device.

[0008] Furthermore, the width of the leveling device on both sides of the opening end of the plow head device is greater than the width of the opening end of the plow head device.

[0009] The width of the leveling device is greater than the width of the opening end of the plow head device but less than the width of the material surface in the concave groove. The purpose is that when the plow head device plows a groove into the material, the plowed material will turn over to both sides. The width of the material turned over on both sides will be greater than the width of the plow head device. Only when the width of the leveling device is greater than the width of the turned-over material can the turned-over material be leveled.

[0010] Furthermore, it also includes a dust collection and buffer silo, a dust cover, and a feeding pipeline. One end of the dust collection and buffer silo is connected to a feeder, and the other end is connected to the feeding pipeline. The dust cover is located above the dust collection and buffer silo to prevent powdery materials from being thrown out. The lower end of the feeding pipeline is connected to a plow head device.

[0011] Furthermore, the plow head device extends deep into the material in the concave groove, and the bottom of the leveling device is flush with the upper surface of the material in the concave groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. When powdery materials are fed, they fall into the furrows plowed by the plow and leveling device. The leveling device then scrapes and covers the powdery materials, preventing them from scattering during transport. This ensures the accuracy of the material composition ratio, maintains the working environment for employees, and reduces labor intensity.

[0014] 2. Dust covers can prevent powdery materials from escaping during the feeding process and causing environmental pollution. Attached Figure Description

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] refer to Figure 1 As shown, the device for preventing the scattering of powdery materials includes a conveyor belt 1, a powdery material hopper 2, a feeder 3, a dust cover 4, a dust collection buffer hopper 5, a feeding pipeline 6, a plow head device 7, and a leveling device 8. The powdery material hopper 2 is connected to the feeder 3. The dust collection buffer hopper 5 is located below the feeder 3. The dust cover 4 is installed in the open space between the feeder 3 and the dust collection buffer hopper 5. The feeding pipeline 6 is connected below the dust collection buffer hopper 5. The plow head device 7 is connected to the lower end of the feeding pipeline 6. The plow head device 7 is fixedly connected to the leveling device 8.

[0023] In this embodiment, the powder material hopper 2 is located downstream of the ordinary hopper 9. The mixed material 12 in the ordinary hopper is discharged first, and the mixed material 12 is transported in the concave groove 11 formed by the conveyor belt 1. Then, the powder material in the powder material hopper 2 is discharged.

[0024] Reference Figure 2 As shown, in this embodiment, the concave groove 11 is an arc-shaped groove surface formed by the roller 13 lifting and bending the two sides of the conveyor belt upwards.

[0025] In this embodiment, both the conveyor belt 1 and the roller 13 are structural components of the belt conveyor, and the conveyor belt 1 drives on the support surface formed by the roller 13.

[0026] In other embodiments, the concave groove 11 can also be formed by fixing baffles on both sides of the conveyor belt to form a groove.

[0027] During the discharge of powdery materials, the dust cover 4 can prevent the powdery materials from escaping into the surrounding environment.

[0028] refer to Figures 1 to 4As shown, the tip 71 of the plow head device 7 faces the direction of the ordinary material bin 9, that is, the upstream direction of the conveying of the mixed material 12, and the opening end 72 of the plow head device 7 faces the downstream direction of the conveying of the mixed material 12. That is, when the mixed material 12 flows, it first passes through the tip 71 of the plow head device 7, and then passes through the opening end 72 of the plow head device 7. When the mixed material 12 passes through the plow head device 7, a furrow is plowed out.

[0029] The leveling device 8 consists of two leveling plates, one end of which is fixedly connected, and the other end is connected to both sides of the opening end 72 of the plow head device 7. The leveling device 8 is roughly triangular with three hollow parts. The width of the leveling device 8 at the widest point on both sides of the opening end 72 is greater than the width of the opening end 72, and also greater than the width of the material turned out on both sides of the plow head device 7, but must be less than the width of the material surface in the concave groove 11.

[0030] The specific operation process of this utility model is as follows:

[0031] like Figure 1 As shown, the ordinary silo 9 is located upstream of the material flow, and the powder material silo 2 is located downstream of the material flow. The ordinary silo 9 continuously feeds the mixed material 12 into the concave trough 11 formed by the conveyor belt 1. The belt conveyor drives the mixed material 12 to be conveyed. When it passes through the plowing device 7, the mixed material 12 is plowed into a trench. At this time, the powder material silo 2 feeds the powder material into the plowed trench through the feeder 3. As the mixed material 12 continues to be conveyed, the turned-up mixed material 12 is scraped flat by the leveling device 8, and the powder material is buried under the mixed material 12. If the conveying continues, the powder material will not be blown away and escape.
