Description

Technical Field

[0001] This utility model relates to the field of metal product processing equipment technology, and more specifically, to a high-efficiency drying equipment for surface treatment of metal products. Background Technology

[0002] In the production of metal products, especially tubular metal products (such as steel pipes and metal fittings), surface treatment (such as cleaning, spraying, and electroplating) is a crucial process. Liquid residue may remain on the surface of the treated workpiece, necessitating effective drying to prevent rusting, uneven coating, or disruption of subsequent processing.

[0003] Currently, for tubular and hollow metal products, the feeding components of existing drying equipment are mostly fixed or have a simple flipping structure. This results in uneven heating areas on the inner wall, outer wall, and ends of the tubular products, easily leading to incomplete drying in certain areas and residual moisture on the surface. Furthermore, traditional flipping mechanisms cannot achieve coordinated "revolutionary conveying + self-rotation drying" actions, preventing the tubular products from fully contacting the heat source. Improving the uniformity and thoroughness of drying tubular metal products is a key technical challenge faced by existing equipment. Therefore, we propose a high-efficiency drying device for metal product surface treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-efficiency drying equipment for surface treatment of metal products, so as to solve the technical problem of the single function of the current drying equipment.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a high-efficiency drying equipment for surface treatment of metal products, comprising a base consisting of a base plate and two supports, a feeding component and a drying device disposed on the top of the base, a first toothed ring for driving the feeding component to rotate on one side of the support of the base, and a power generation component that generates electricity in coordination with the rotation of the feeding component on the top of the base. The feeding assembly includes a water wheel, and the inner side of the water wheel is provided with several sets of partition plates and several flipping parts for placing tubular products. The base has two brackets with first toothed rings on their outer walls that cooperate with the flipping component, and the cooperation between the first toothed rings and the flipping component can control the rotation of the tubular product.

[0006] This invention utilizes the overall revolution of the water wheel, combined with the independent rotation of the tilting component, to allow tubular products to both circulate with the water wheel and rotate 360° around the drive rod during the drying process. This "revolution + rotation" motion mode effectively solves the drying dead zones caused by partial obstruction of tubular products, ensuring that the inner and outer walls, as well as the front and rear ends, of the products are evenly contacted by the drying airflow. This addresses the pain point of traditional drying equipment, which results in "partial over-drying and partial under-drying," significantly improving the drying qualification rate.

[0007] Preferably, the flipping component includes a drive rod that is rotatably connected to the water wheel. A bearing box that fits against the inner wall of the water wheel is provided on the rod wall of the drive rod, and the bearing box rotates around the rod wall of the drive rod. The cross-section of the bearing box is C-shaped, and the end of the drive rod is provided with a driven tooth that meshes with the drying equipment.

[0008] Preferably, the outer wall of the carrier box is provided with ventilation holes, and the top of the carrier box is provided with a weighing block to increase the weight of the bottom, and the weight of the weighing block is greater than the weight of the tubular product.

[0009] Preferably, the power generation component includes a generator, the output end of the generator is provided with a gearbox, the connecting part of the gearbox is provided with a drive tooth, and a second toothed ring that is connected to the outer wall of the water turbine is engaged on the outer side of the drive tooth.

[0010] Preferably, a battery is electrically connected to the top of the generator, and the battery is electrically connected to the drying equipment and the motor, and the stored energy in the battery can be used to start the motor.

[0011] Preferably, the inner wall of the carrier box is smooth, and the rod wall of the drive rod is provided with a rubber sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the overall revolution of the water wheel, combined with the independent rotation of the tilting component, to enable tubular products to both circulate with the water wheel and rotate 360° around the drive rod during the drying process. This "revolution + rotation" motion mode effectively solves the drying dead zones caused by partial obstruction of tubular products, ensuring that the inner and outer walls, front and rear ends of the product are evenly contacted by the drying airflow. This addresses the pain point of "partial over-drying and partial under-drying" in traditional drying equipment, significantly improving the drying qualification rate.

[0013] 2. This invention also converts the mechanical energy of the water turbine's revolution into electrical energy through a power generation component. When the water turbine rotates, it drives the second gear ring to engage the drive teeth. After adjustment by the gearbox, the drive generator generates electricity, which is stored in a battery and then used to power the drying equipment and drive motor. This design significantly reduces dependence on the external power grid, especially during continuous batch operations, thus reducing operating costs. Attached Figure Description

[0016] like Figures 1 to 6 As shown, this utility model relates to a high-efficiency drying device for surface treatment of metal products, including a base 1 consisting of a base plate and two supports. A feeding assembly 2 and a drying device 3 are arranged on the top of the base 1. A first toothed ring 4 that drives the feeding assembly 2 to rotate is arranged on one side of the support of the base 1. A power generation assembly 6 that works with the rotation of the feeding assembly 2 to generate electricity is also arranged on the top of the base 1. The main structure of the drying device 3 includes a fan and an electric heating structure, which are existing technologies and will not be described in detail here. The tubular products in the covered area can be dried by blowing hot air downwards through the drying device 3. The design of the power generation assembly 6 can achieve self-powered operation and reduce energy consumption.

[0017] The feeding assembly 2 includes a water wheel 201. The inner side of the water wheel 201 is provided with several sets of partition plates 202 and several flipping parts 7 for placing tubular products. The water wheel 201 can be easily rotated and circulated, while the partition plates 202 can divide the drying area and improve the drying effect of individual tubular products.

[0018] The outer walls of the two supports of the base 1 are provided with first toothed rings 4 that cooperate with the flipping component 7, and the cooperation between the first toothed rings 4 and the flipping component 7 can control the rotation of the tubular product; the rotation of the tubular product can improve the overall drying and reduce the existence of dead corners.

[0019] In an embodiment of this utility model, the flipping component 7 includes a drive rod 701 rotatably connected to the water wheel 201. A support box 702 that fits against the inner wall of the water wheel 201 is provided on the rod wall of the drive rod 701, and the support box 702 rotates around the rod wall of the drive rod 701. The cross-section of the support box 702 is C-shaped, and the end of the drive rod 701 is provided with a driven tooth 704 that meshes with the drying equipment 3. The position of the support box 702 can be restricted by the support of the drive rod 701, the C-shaped design can restrict the placement position of the tubular product, and the rotation design ensures that the rotation of the drive rod 701 will not cause the support box 702 to rotate synchronously. The engagement of the driven tooth 704 with the first toothed ring 4 achieves the effect of driving the rotation.

[0020] In an embodiment of this utility model, a vent hole 703 is provided on the outer wall of the carrier box 702, and a weighing block 705 is provided on the top of the carrier box 702 to increase the weight of the bottom, and the weight of the weighing block 705 is greater than the weight of the tubular product; the vent hole 703 is provided on the outer wall of the carrier box 702 to enhance the contact efficiency between the hot airflow generated by the drying equipment 3 and the surface of the tubular product, avoid the formation of "thermal barrier" inside the carrier box 702, and improve the drying speed. The weighing block 705 is provided on the top of the carrier box 702, and its weight is greater than that of the tubular product. By utilizing the principle of gravity balance, it ensures that the carrier box 702 always maintains a stable "opening upward" posture during its rotation, while not affecting the overall rotation.

[0021] In an embodiment of this utility model, the power generation component 6 includes a generator 601. The output end of the generator 601 is provided with a gearbox 602. The connecting part of the gearbox 602 is provided with a drive tooth 603. A second toothed ring 604 connected to the outer wall of the water turbine 201 is meshed on the outer side of the drive tooth 603. When the water turbine 201 rotates, the second toothed ring 604 connected to its outer wall rotates synchronously. By meshing with the drive tooth 603, the speed is adjusted by the gearbox 602 and then drives the generator 601 to generate electricity, converting the mechanical energy of the water turbine 201 into electrical energy, thereby realizing energy recovery.

[0022] In this embodiment of the invention, a storage battery 605 is electrically connected to the top of the generator 601, and the storage battery 605 is electrically connected to the drying equipment 3 and the motor 5. The stored electrical energy in the storage battery 605 can be used to start the motor 5. The electrical energy generated by the generator 601 is stored in the storage battery 605, and the storage battery 605 is electrically connected to the drying equipment 3 and the drive motor 5 (presumably the power source that drives the water turbine 201 to rotate), forming a "self-sufficient energy" auxiliary system. It is particularly noteworthy that "the stored electrical energy in the storage battery 605 can be used to start the motor 5," meaning that the equipment can utilize recovered energy to assist in starting, reducing the instantaneous load on the external power supply and improving energy efficiency.

[0023] In the embodiments of this utility model, the inner wall of the carrier box 702 is smooth, and the rod wall of the drive rod 701 is provided with a rubber sleeve. The smooth surface design reduces the frictional force in contact with the tubular product, while the rubber sleeve design increases the frictional resistance between the tubular product and the tubular product, thereby driving the tubular product to rotate synchronously when rotating.

[0024] Working principle: This embodiment provides a high-efficiency drying equipment for surface treatment of metal products. Before the equipment is started, the battery 605 stores sufficient electrical energy in advance. When the equipment is started, it directly supplies power to the drive motor 5. The motor 5 outputs power to drive the water wheel 201 of the feeding component 2 to start rotating, completing the initial start of the equipment. When the water wheel 201 keeps rotating at a low speed, the second toothed ring 604 connected to its outer wall synchronously meshes with the drive tooth 603 of the power generation component 6, driving the generator 601 to operate and generate electrical energy. Electrical energy is transmitted and stored in battery 605, forming a cycle of "water turbine 201 rotation - power generation - energy storage - power supply". Battery 605 can continuously power the drying equipment 3 and motor 5, reducing external energy consumption. The stored energy also ensures the motor 5 can start up next time. The tubular metal products to be dried are placed one by one into the flipping component 7 of the feeding assembly 2. The bearing box 702 of the flipping component 7 has a C-shaped cross-section, which stably supports the tubular products. The inner wall of the bearing box 702 is smooth to avoid scratching the product surface and reduce friction. The rubber sleeve on the drive rod 701 increases the friction between the product and the tubular product. Driven by motor 5, water turbine 201 continuously rotates. The partition plate 202 on its inner side evenly separates the multiple flipping components 7, forming independent material conveying units. As water turbine 201 rotates, the flipping components 7 carry the tubular products along the circumferential trajectory of water turbine 201, sequentially passing through the drying area of ​​the drying equipment 3, achieving continuous feeding and conveying. The water wheel 201 rotates around its own axis, driving all the flipping parts 7 and tubular products to move synchronously in a circular motion. This ensures that each product enters the effective heating range of the drying equipment 3 in sequence, avoiding insufficient drying in certain areas. As the flipping parts 7 move with the water wheel 201, the driven teeth 704 at the end of the drive rod 701 continuously mesh with the first toothed ring 4 on the outer wall of the base 1 support. The relative displacement generated by the revolution of the water wheel 201 is converted into the rotational power of the drive rod 701 through tooth meshing. This, in turn, drives the tubular products to rotate synchronously with the drive rod 701, achieving automatic face-changing drying. The weighing block 705 on the top of the support box 702 is heavier than the tubular products. Utilizing the principle of gravity balance, it ensures that the support box 702 always keeps its opening facing upwards during rotation, preventing the tubular products from falling. At the same time, the ventilation holes 703 on the outer wall of the support box 702 allow the hot airflow generated by the drying equipment 3 to fully penetrate and make full contact with the surface of the products. Combined with the rotation, this achieves drying without dead angles, significantly improving drying uniformity and efficiency.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
