Description

Technical Field

[0001] This utility model relates to the field of powder silo cone bucket technology, and in particular to a corrosion-resistant reinforcement mechanism for the weld seam of a powder silo cone bucket. Background Technology

[0002] Powder silos are widely used storage devices in industries such as metallurgy, chemicals, building materials, and grain. Before use, powder silos need to be welded and secured to ensure their integrity. In the prior art, when powder, especially high-hardness material, is subjected to gravity, it continuously impacts the weld area inside the cone hopper, which can easily cause severe erosion and wear inside the cone hopper. The weld area does not have further protection, which seriously affects the service life of the cone hopper. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where powder materials under gravity easily cause severe erosion and wear inside the cone hopper, reducing the service life of the cone hopper. Therefore, this invention proposes a corrosion-resistant reinforcement mechanism for the weld seam of the powder hopper cone hopper.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A corrosion-resistant reinforcement mechanism for the weld seam of a powder silo cone bucket includes: The cone-shaped bucket body and the reinforcing frame are arranged inside the reinforcing frame. The cone-shaped bucket body is composed of multiple iron plates spliced ​​together, with a connecting section between two adjacent iron plates. The connecting section includes a weld and an isolation layer sprayed on the outside of the weld. The reinforcing frame is welded and fixed to the outer wall of the cone-shaped bucket body. The isolation layer isolates the corrosive medium from direct contact with the weld, while the reinforcing frame enhances the structural strength of the cone-shaped bucket body.

[0005] In one possible design, the reinforcing frame includes multiple vertical plates and multiple inclined plates, the bottom ends of the multiple vertical plates are fixedly connected to the top ends of the multiple inclined plates, and the inner walls of the vertical plates and inclined plates are attached to and welded to the outer wall of the cone-shaped body.

[0006] In one possible design, the reinforcing frame further includes two top rings, which are respectively fixedly connected to the top and bottom of the plurality of vertical plates.

[0007] In one possible design, the reinforcing frame further includes a bottom ring and at least one protective frame, the bottom ring being fixedly connected to the bottom end of the plurality of inclined plates, and the protective frame being fixedly connected to the outer wall of the plurality of inclined plates.

[0008] In one possible design, the joints between the vertical plate, the inclined plate, and the outer wall of the cone-shaped body are all fixed by welding, so that the stress can be effectively distributed.

[0009] In one possible design, a guide pipe is fixedly connected to the bottom end of the cone-shaped hopper body.

[0010] In this application, the main body of the cone bucket is welded together from multiple iron plates, leaving a connecting section at the weld. The connecting section consists of an insulating layer and a weld. The weld is located between two iron plates, and the insulating layer is attached to the outside of the weld. The welded main body of the cone bucket is placed inside a reinforcing frame. The upper half of the reinforcing frame is fixed by welding two top rings to the top and bottom of four vertical plates respectively. The lower half of the reinforcing frame is fixed by welding four inclined plates and two protective frames. The bottom ring is fixedly welded to the bottom of the four inclined plates, and the top of the four inclined plates is welded to the bottom of the four vertical plates. After the main body of the cone bucket is placed inside the reinforcing frame, the joints between the vertical plates, inclined plates and the outside of the main body of the cone bucket are welded and fixed, thereby further increasing the strength of the main body of the cone bucket.

[0011] Beneficial effects: In this utility model, the anti-corrosion reinforcement mechanism for the weld of the powder silo cone bucket consists of a connecting section composed of an isolation layer and a weld. The weld is located between iron plates, and the isolation layer is sprayed on the outside of the weld, which effectively isolates the direct contact between the corrosive medium and the weld, forming a reliable anti-corrosion barrier, greatly enhancing the anti-corrosion capability of the weld of the powder silo cone bucket, and extending the service life of the equipment. In this utility model, the anti-corrosion reinforcement mechanism for the weld seam of the powder silo cone bucket consists of a cone bucket body made of multiple iron plates welded together and placed inside a reinforcing frame. The reinforcing frame is fixed by welding multiple components. After the cone bucket body is placed in, it is welded and fixed at the joint where it fits with the vertical plate and the inclined plate of the reinforcing frame. This structural design makes the overall structure more stable, effectively disperses stress, and significantly improves the structural strength of the weld seam of the powder silo cone bucket. This invention not only enhances corrosion resistance through a unique anti-corrosion design, reducing the risk of equipment damage caused by corrosion, but also strengthens the structure through a reasonable structural layout, ensuring stable operation of the equipment. The two complement each other, effectively improving the reliability and durability of the cone hopper weld of the powder silo and reducing maintenance costs. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one embodiment: Refer to Figure 1 and Figure 2 A weld corrosion protection and reinforcement mechanism is mainly composed of a cone-shaped body 1 and a reinforcing frame 2, with the cone-shaped body 1 located inside the reinforcing frame 2. The cone-shaped body 1 is composed of four iron plates spliced ​​together, with a connecting section 4 reserved between two adjacent iron plates. This connecting section 4 is used for welding two adjacent iron plates.

[0016] Reference Figure 3 The connecting section 4 consists of an insulating layer 5 and a weld 6. The weld 6 is located between two adjacent iron plates. After the iron plates are welded, the insulating layer 5 is evenly sprayed onto the outside of the weld 6. The insulating layer 5 is made of a material with good corrosion resistance, such as epoxy resin coating. The spraying thickness is controlled between 0.5 and 1 mm to ensure effective isolation of corrosive media from direct contact with the weld 6, forming a reliable anti-corrosion barrier and enhancing the corrosion resistance of the powder silo cone hopper weld.

[0017] Reference Figure 4 The reinforcing frame 2 consists of four vertical plates 8, four inclined plates 11, two top rings 7, and two protective frames 10. The four vertical plates 8 are arranged in a circle, and the two top rings 7 are fixedly connected to the top and bottom of the four vertical plates 8 respectively by welding. During welding, it is ensured that the top rings 7 are perpendicular to the vertical plates 8 and that the weld is firm and seamless. The bottom ends of the four vertical plates 8 and the top ends of the four inclined plates 11 are fixed by welding. Before welding, the contact surfaces need to be ground to remove oxide layers and impurities to ensure welding quality.

[0018] Reference Figure 4 The bottom ends of the four inclined plates 11 are fixedly connected to a bottom ring 9 by welding. The bottom ring 9 is perpendicular to the inclined plate 11. After welding, a visual inspection is performed to ensure that there are no missing welds or incomplete welds. The outer walls of the four inclined plates 11 are fixedly connected to two protective frames 10. The two protective frames 10 are placed vertically and are located above the bottom ring 9. The protective frames 10 are fixed to the inclined plates 11 by welding. During the welding process, care should be taken to control welding deformation to ensure the fit between the protective frames 10 and the inclined plates 11.

[0019] Reference Figure 1 and Figure 4The welded cone-shaped body 1 is placed inside the reinforcing frame 2, and its position is adjusted so that it fits against the vertical plate 8 and the inclined plate 11 of the reinforcing frame 2. Then, the vertical plate 8 and the inclined plate 11 are welded and fixed to the outside of the cone-shaped body 1. During welding, a layered and segmented welding method is used to control the welding current and voltage to avoid generating excessive thermal stress and further enhance the strength of the cone-shaped body 1.

[0020] This application can be used in the field of powder silo cone buckets, or in other fields applicable to this application.

[0021] In another embodiment: Reference Figure 1 A corrosion-resistant reinforcement mechanism for the weld seam of a powder silo cone bucket is applied to the field of powder silo cone buckets. A guide pipe 3 is fixedly connected to the bottom end of the cone bucket body 1. The guide pipe 3 is connected to the cone bucket body 1 by welding. Before welding, the connection part is preheated to reduce the generation of welding cracks. After welding, a sealing test is performed to ensure that the guide pipe 3 is tightly connected to the cone bucket body 1 and there is no leakage.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
