Description

Technical Field

[0001] This utility model relates to the field of rust prevention technology, and in particular to a rust prevention device for metal frames. Background Technology

[0002] In the metal products processing industry, metal frames are highly susceptible to corrosion due to long-term exposure to air, moisture, and various corrosive environments. This not only affects their appearance but also weakens their structural strength and shortens their service life. Therefore, effective rust prevention treatment of metal frames is a crucial step in the production process. Currently, rust prevention of metal frames is mostly achieved through manual spraying of rust inhibitors. However, this method has several drawbacks: Firstly, manual spraying is extremely inefficient, requiring workers to operate on each metal frame individually, making it difficult to meet the needs of large-scale production. Secondly, manual spraying results in poor uniformity; due to differences in workers' techniques and experience, the rust inhibitor is easily unevenly distributed on the metal frame surface, with some areas being over-sprayed, leading to waste, while other areas are under-sprayed, failing to form an effective rust-proof protective layer, thus affecting the rust prevention effect. Furthermore, manual operation is also affected by factors such as worker labor intensity and fatigue, further reducing the stability of the treatment quality. Therefore, there is an urgent need for a rust prevention device that can overcome the shortcomings of manual spraying and improve the efficiency and quality of rust prevention treatment for metal frames. Utility Model Content

[0003] The purpose of this invention is to provide a metal frame rust prevention treatment device that can overcome the defects of manual spraying, improve the efficiency and quality of metal frame rust prevention treatment, and reduce the waste caused by manual spraying.

[0004] The present invention adopts the following technical solution: A rust prevention treatment device for metal frames includes a treatment tank containing rust removal liquid, and a reciprocating conveyor installed on the treatment tank. The reciprocating conveyor enters from one end of the treatment tank and exits from the other end. Multiple hanging parts are spaced apart on the side of the reciprocating conveyor along its running direction.

[0005] Preferably, after one end of the reciprocating conveyor exits from the treatment pool, it runs through the bottom of the treatment pool to the initial position.

[0006] Preferably, the reciprocating conveyor includes horizontal sections located on both sides of the upper part of the treatment pool and inside the treatment pool, and the horizontal sections inside the treatment pool are connected to the horizontal sections located on both sides of the upper part of the treatment pool by inclined sections.

[0007] Preferably, the bottom of the treatment pool is provided with a receiving cavity with two open ends, and the reciprocating conveyor running to the bottom of the treatment pool passes through the receiving cavity.

[0008] Preferably, the mounting parts are located on both sides of the reciprocating conveyor.

[0009] Preferably, the hanging part is a rod-shaped structure, and a baffle is provided at the end away from the reciprocating conveyor.

[0010] Preferably, the hanging part is provided with a top plate at one end near the reciprocating circulating conveyor, the top plate extending towards the baffle, wherein a slot for placing a metal frame is formed between the top plate and the baffle.

[0011] Preferably, the bottom of the hanging part is provided with a mesh structure.

[0012] Preferably, the mounting part is detachably connected to the reciprocating conveyor.

[0013] Preferably, the treatment tank is provided with a discharge port and a supply port, the supply port is connected to a supply pump, and the discharge port is provided with a valve.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes a reciprocating conveyor to transport the metal frames suspended on the mounting section, achieving automated and continuous rust prevention treatment of the metal frames. It eliminates the need for manual operation, allowing multiple metal frames to be processed simultaneously, effectively adapting to large-scale production needs and significantly improving the overall efficiency of rust prevention treatment. The metal frames enter the treatment tank via the reciprocating conveyor, ensuring full contact with the rust-removing liquid, which evenly covers the surface of the metal frames. This avoids the problem of uneven distribution of rust inhibitor caused by differences in operating techniques and experience during manual spraying, ensuring that each metal frame receives consistent and effective rust prevention treatment, thus improving the stability and reliability of the rust prevention effect.

[0015] This invention's automated processing reduces reliance on manual labor, thus lowering labor costs. Simultaneously, it eliminates the need for workers to perform tedious spraying operations, reducing labor intensity and improving the working environment. Furthermore, the rust-removing liquid in the treatment tank can be recycled, effectively reducing rust-removing liquid consumption compared to the tendency for excessive use of rust inhibitors in manual spraying, saving resources and lowering production costs.

[0016] Figure 1 This is a front view of an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the mounting part in an embodiment of this application. Detailed Implementation

[0017] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 2 As shown, the rust prevention treatment device for metal frames according to this utility model includes a treatment tank 1, with a discharge port 2 and a replenishment port on the treatment tank 1. The replenishment port is connected to a replenishment pump 3, and a valve is installed at the discharge port 2. The treatment tank 1 contains a rust-removing liquid, which typically uses a formula commonly found in existing technologies, including acids, corrosion inhibitors, surfactants, and additives. A reciprocating conveyor 4 is installed on the treatment tank 1, entering from one end of the treatment tank 1 and exiting from the other end. Multiple hanging parts 5 are spaced along the side of the reciprocating conveyor 4 along its running direction for hanging the metal frame. In this embodiment, the reciprocating conveyor 4 preferably uses a conveyor chain plate, which can be made of stainless steel or corrosion-resistant engineering plastics, with a flat surface, strong load-bearing capacity, and can have hanging parts 5 on the side for secure connection. The small gap between the chain plates effectively prevents the metal frame from shaking, and it has excellent corrosion resistance and wear resistance, making it suitable for long-term contact with the rust-removing liquid.

[0018] Furthermore, after exiting from the treatment tank 1 at one end, the reciprocating conveyor 4 runs through the bottom of the treatment tank 1 back to its initial position. This arrangement allows the reciprocating conveyor 4 to effectively avoid contact with the rust-preventive liquid during its downward return. Since some structures come into contact with the rust-preventive liquid when the conveyor transports the metal frame into the treatment tank 1, running through the bottom during the return phase reduces additional contact with the rust-preventive liquid, especially preventing excessive residue or accumulation of the rust-preventive liquid on the conveyor components due to gravity during the downward movement. This not only reduces the risk of corrosion from the rust-preventive liquid on unnecessary contact parts of the conveyor, but also reduces dripping and loss of the rust-preventive liquid during conveyor operation, extending the service life of the conveyor and reducing equipment maintenance costs. In addition, this arrangement successfully prevents the hanging part 5 on the reciprocating conveyor 4 from obstructing the metal frame during its downward movement. If the conveyor uses other return paths, such as descending above or to the side of the treatment tank 1, the hanging part 5 may spatially intersect or interfere with the metal frame being transported within the treatment tank 1. When running through the bottom, the hanging part 5 is located in an independent space at the bottom of the treatment pool 1, completely separated from the conveying path of the metal frame undergoing rust prevention treatment above. This does not affect the normal operating trajectory of the metal frame in the treatment pool 1, ensuring the continuity and stability of the entire conveying and processing process and improving the safety of equipment operation.

[0019] Furthermore, the reciprocating conveyor 4 includes horizontal sections located on both sides of the upper part of the treatment pool 1 and inside the treatment pool 1. The horizontal sections inside the treatment pool 1 are connected to the horizontal sections on both sides of the upper part of the treatment pool 1 via inclined sections. The setting of the upper horizontal section of the treatment pool 1 facilitates the placement of the metal frame onto the hanging part 5, while also ensuring the consistency of the hanging position, laying a good foundation for the subsequent rust prevention treatment of the metal frame in the treatment pool 1. The setting of the inclined section realizes a smooth transition of the metal frame from the upper horizontal section to the horizontal section inside the treatment pool 1. If a direct vertical drop connection is used, the metal frame may be displaced or even damaged due to severe impact during the transfer process, and it will also put a large load on the structure of the conveyor. The inclined section guides the metal frame into the treatment pool 1 gradually through a gentle slope, allowing the metal frame to be immersed in the rust removal liquid in a stable posture, avoiding component damage or affecting the treatment effect due to instantaneous force, and ensuring the continuity and safety of the entire conveying process. The horizontal section inside the treatment tank allows the metal frame to remain horizontal for a period of time within the treatment tank 1, ensuring that all parts of the metal frame can fully and evenly contact the rust removal liquid. Compared to an inclined state or a brief passage, horizontal residence allows the rust removal liquid sufficient time to react with the rust products on the surface of the metal frame, thoroughly removing the rust. This ensures the depth and uniformity of the rust prevention treatment, meeting the stringent requirements of production for rust removal effectiveness.

[0020] In this embodiment, a receiving cavity with open ends is also provided at the bottom of the treatment pool 1, through which the reciprocating conveyor 4, running to the bottom of the treatment pool 1, passes. The receiving cavity provides structural protection for the reciprocating conveyor 4, reducing damage from external collisions. In the production environment surrounding the treatment pool 1, there may be operations involving the handling of metal frames or other equipment. The receiving cavity can provide physical protection for the descending conveyor, preventing problems such as conveyor deformation and component damage due to accidental collisions, extending the service life of the conveyor, and reducing equipment maintenance costs.

[0021] Furthermore, in this embodiment, the hanging part 5 is arranged on both sides of the reciprocating conveyor 4 to increase the number of hanging stations for the metal frame and improve work efficiency. The hanging part 5 is a rod-shaped structure, with a baffle 6 at the end furthest from the reciprocating conveyor. The baffle 6 prevents the metal frame from being buoyed out of the hanging part 5 after entering the treatment tank 1. In addition, a top plate 7 is provided at the end of the hanging part 5 closest to the reciprocating conveyor, extending towards the baffle 6, forming a slot 8 for placing the metal frame between the top plate 7 and the baffle 6. The baffle 6 further prevents the metal frame from being buoyed out of the hanging part 5 after entering the treatment tank 1. The metal frame is fitted onto the hanging part 5 through the slot 8, and the top of the metal frame is moved below the top plate 7, thus limiting the vertical position of the metal frame. Preferably, the bottom of the hanging part 5 is designed with a mesh structure. This design helps the rust-preventive liquid to flow through the mesh and contact the end face of the metal frame that contacts the hanging part 5, thereby ensuring the rust removal effect. In this embodiment, the hanging part 5 is detachably connected to the reciprocating conveyor to facilitate subsequent targeted replacement and maintenance. Preferably, a threaded rod is provided on the hanging part 5, and a threaded hole for air supply installation is provided on the reciprocating conveyor.

[0022] In operation, this invention simply requires hanging the metal frame on the hanging part 5 at the initial end of the reciprocating circulating conveyor. As the reciprocating circulating conveyor carries the metal frame gradually into the treatment tank 1, it comes into contact with the rust-preventive liquid. The rust-preventive liquid can evenly cover the surface of the metal frame, avoiding the problem of uneven distribution of rust inhibitor caused by differences in operation techniques and experience during manual spraying. This ensures that each metal frame receives consistent and effective rust prevention treatment, improving the stability and reliability of the rust prevention effect. After the rust-preventive treatment, the metal frame is removed from the treatment tank 1 by the reciprocating circulating conveyor and can then be removed.
