Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, to a dust removal frame with anti-corrosion coating. Background Technology

[0002] In industrial dust removal systems, the dust collector frame is a key component that supports the dust collector filter bag, and its performance directly affects the dust removal efficiency and the service life of the filter bag.

[0003] Currently, conventional dust collector frames are mostly made of metal. In complex industrial environments, especially in conditions containing corrosive gases such as acids and alkalis or high humidity, metal frames are highly susceptible to corrosion, leading to decreased frame strength, deformation, or even breakage. This, in turn, affects the normal operation of the dust collection system, increasing maintenance costs and equipment downtime. Although some dust collector frames use a single coating for corrosion protection, this single coating is prone to peeling and wear during long-term use, making it difficult to meet the requirements of industrial production for the corrosion resistance and durability of dust collector frames. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a dust collector frame with anti-corrosion coating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant coated dust collector frame, comprising a fixed frame, wherein a frame support strip is fixedly connected to the inner side of the fixed frame, and the fixed frame and the frame support strip are provided with a bottom protective layer, a first intermediate protective layer, a second intermediate protective layer, and an outer anti-fouling layer from the inside out. The fixed frame and the frame support strip are both made of stainless steel, the bottom protective layer is made of zinc-aluminum alloy, the first intermediate protective layer is made of ceramic fiber, the second intermediate protective layer is made of graphene-modified resin, and the outer anti-fouling layer is made of titanium dioxide nanoparticles.

[0006] As a preferred technical solution of this utility model, the bottom protective layer is coated on the surface of the fixing frame or skeleton support strip by hot-dip galvanizing process, and its thickness is 0.1-0.3mm.

[0007] As a preferred embodiment of this utility model, the first intermediate protective layer is coated onto the surface of the bottom protective layer with an adhesive, the thickness of the first intermediate protective layer is 0.2-0.5mm, and the adhesive is epoxy resin glue.

[0008] As a preferred embodiment of this utility model, the second intermediate protective layer is coated onto the surface of the first intermediate protective layer using a spraying process, and the thickness is 0.1-0.2 mm.

[0009] As a preferred embodiment of this invention, the outer anti-fouling layer is coated onto the surface of the second intermediate protective layer by a sol-gel method, with a thickness of 0.05-0.1 mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model improves the corrosion resistance of the dust collector frame from multiple aspects, such as electrochemical protection, physical isolation, chemical protection and self-cleaning, through the synergistic effect of the bottom protective layer, the first intermediate protective layer, the second intermediate protective layer and the outer anti-fouling layer, and effectively extends the service life of the dust collector frame.

[0011] 2. This utility model utilizes the complementary properties of different materials. The bottom protective layer provides electrochemical protection, the first intermediate protective layer enhances high temperature resistance and wear resistance, the second intermediate protective layer forms a dense barrier, and the outer anti-fouling layer achieves self-cleaning. This enables the dust collector frame to adapt to complex industrial environments. The layers are tightly bonded and have good flexibility and buffering properties, which can resist the impact of external mechanical forces to a certain extent, prevent frame deformation and damage, and improve the stability of the dust collection system.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1 to 2 As shown, this utility model provides a corrosion-resistant coated dust collector frame, including a fixed frame 1, with a frame support strip 2 fixedly connected to the inner side of the fixed frame 1. The fixed frame 1 and the frame support strip 2 are provided with a bottom protective layer 3, a first intermediate protective layer 4, a second intermediate protective layer 5, and an outer anti-fouling layer 6 from the inside out. The fixed frame 1 and the frame support strip 2 are both made of stainless steel, the bottom protective layer 3 is made of zinc-aluminum alloy, the first intermediate protective layer 4 is made of ceramic fiber, the second intermediate protective layer 5 is made of graphene-modified resin, and the outer anti-fouling layer 6 is made of titanium dioxide nanoparticles.

[0015] The bottom protective layer 3 is coated onto the surface of the fixing frame 1 or the skeleton support strip 2 by hot-dip galvanizing. Its thickness is 0.1-0.3mm. Zinc-aluminum alloy has good electrochemical protection performance. Zinc is more reactive than iron. When the coating surface is damaged, the bottom protective layer 3 can be preferentially corroded, thereby protecting the metal substrate of the dust collector skeleton and playing the role of sacrificial anode protection, effectively preventing electrochemical corrosion of the dust collector skeleton. At the same time, the bottom protective layer 3 has good bonding force with the dust collector skeleton and can be tightly attached to the skeleton surface, improving the stability of the entire composite structure.

[0016] The first intermediate protective layer 4 is coated onto the surface of the bottom protective layer 3 with an adhesive. The thickness of the first intermediate protective layer 4 is 0.2-0.5mm. The adhesive is epoxy resin glue. Ceramic fiber has excellent high temperature resistance, corrosion resistance and wear resistance, which can effectively resist the erosion of the dust collector frame by high temperature, acid and alkali and other corrosive media, and further enhance the corrosion resistance of the dust collector frame. In addition, the first intermediate protective layer 4 has a loose texture and a certain buffering effect, which can reduce the impact of external mechanical force on the frame and protect the frame structure from damage.

[0017] The second intermediate protective layer 5 is coated onto the surface of the first intermediate protective layer 4 using a spraying process, with a thickness of 0.1-0.2 mm. Graphene possesses extremely high mechanical strength and chemical stability; when combined with resin, it significantly improves the resin's strength, hardness, and impermeability. The second intermediate protective layer 5 effectively prevents the penetration of corrosive media, forming a dense protective barrier. Simultaneously, this protective layer exhibits good flexibility and adhesion, allowing it to adhere tightly to the surface of the first intermediate protective layer 4. Even with slight deformation of the framework, cracking and peeling are unlikely to occur.

[0018] The outer antifouling layer 6 is coated onto the surface of the second intermediate protective layer 5 using a sol-gel method, with a thickness of 0.05-0.1 mm. The titanium dioxide nanoparticles have photocatalytic self-cleaning properties. Under light conditions, they can decompose organic pollutants and dust adsorbed on the surface of the dust collector frame, making them easy to remove. This keeps the surface of the dust collector frame clean, reduces dust accumulation on the frame surface, and lowers the risk of wear and corrosion caused by dust accumulation. In addition, the outer antifouling layer 6 also has a certain degree of hydrophobicity, which can reduce the adhesion of water on the frame surface and further improve the corrosion resistance of the dust collector frame.

[0019] Working principle and usage process of this utility model: Through the synergistic effect of the bottom protective layer 3, the first intermediate protective layer 4, the second intermediate protective layer 5, and the outer anti-fouling layer 6, the corrosion resistance of the dust collector frame is improved from multiple aspects such as electrochemical protection, physical isolation, chemical protection and self-cleaning, effectively extending the service life of the dust collector frame. The properties of different materials complement each other. The bottom protective layer 3 provides electrochemical protection, the first intermediate protective layer 4 enhances high temperature resistance and wear resistance, the second intermediate protective layer 5 forms a dense barrier, and the outer anti-fouling layer 6 achieves self-cleaning, enabling the dust collector frame to adapt to complex industrial environments. The layers are tightly bonded and have good flexibility and buffering properties, which can resist the impact of external mechanical forces to a certain extent, prevent the frame from deforming and being damaged, and improve the stability of the dust collection system. The photocatalytic self-cleaning properties of the external anti-fouling layer 6 can reduce the accumulation of dust and contaminants on the surface of the skeleton, reduce maintenance costs, and improve dust removal efficiency.
