Description

Technical Field

[0001] This utility model belongs to the field of linear aluminum conductor processing technology, and specifically relates to a drying device for the production of linear aluminum conductors. Background Technology

[0002] Wire aluminum conductors are wire-shaped metal materials made of pure aluminum or aluminum alloys, primarily used for power transmission, and are characterized by their light weight and low cost. In the continuous extrusion production process of wire aluminum conductors, the straightened aluminum rods are typically cleaned to remove impurities such as oil and oxide scale from their surface. After cleaning, the aluminum rods are dried to prevent moisture from being carried into the subsequent extrusion cavity, which could lead to defects such as bubbles in the extruded products.

[0003] Existing continuous aluminum rod drying equipment generally uses a circular integral or square split cavity connected to a blower to dry the aluminum rods that pass axially through the cavity. However, in actual use, the aluminum rods often rub against the inner wall of the cavity, resulting in cavity wear and affecting the service life of the drying equipment. In addition, the moisture and impurities blown out of the cavity are not easy to collect and will fall onto the workshop floor, increasing the workload of subsequent processing. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a drying device for the production of linear aluminum conductors. The specific technical solution is as follows: This utility model provides a drying device for producing linear aluminum conductors, including a support platform with a groove on the top surface of the support platform. U-shaped openings are vertically and symmetrically formed on both ends of the groove. Lugs are vertically and symmetrically connected to the bottom sides of the outer surfaces of the U-shaped openings. A guide wheel is rotatably connected between the two lugs, and an aluminum rod to be dried is continuously supported between the two guide wheels. A water-blowing assembly is provided on the bottom surface of the groove. The water blowing assembly includes a main air duct suspended parallel to the aluminum rod directly below it. Both ends of the main air duct are fixedly supported by brackets fixed to the bottom surface of the box groove. An L-shaped air inlet pipe is connected to the middle of the bottom surface of the main air duct. The horizontal part of the air inlet pipe passes through the corresponding side of the box groove and is connected to the air outlet of the blower suspended on the corresponding outer side of the box groove. Multiple branch air ducts are symmetrically connected at equal intervals along the direction of the aluminum rod on both sides of the main air duct. The top opening of each branch air duct is detachably connected to an air outlet, and the air outlet is tilted downward and radially aligned with the aluminum rod.

[0005] As a preferred technical solution of this utility model, the support platform includes a bracket that is interference-fitted with the bottom of the box groove. Angle steel legs are vertically and symmetrically connected to the four corners of the bottom surface of the bracket, and a pad is vertically connected to the bottom end of the four angle steel legs.

[0006] As a preferred technical solution of this utility model, a straight water pipe is vertically connected to a corner of the bottom surface of the tank, and the gap of the straight water pipe passes through the bottom surface of the tray. The bottom end of the water tray is detachably connected to a water bend, and the bottom opening of the water bend is aligned with the opening of the water receiving trough placed on the top surface of the pad.

[0007] As a preferred technical solution of this utility model, a pair of protrusions are vertically and symmetrically connected to the top inner sides of the two U-shaped openings, and a guide roller is longitudinally rotatably connected between each protrusion and the inner bottom surface of the U-shaped opening, with an aluminum rod passing through the gap between the two pairs of guide rollers.

[0008] As a preferred technical solution of this utility model, the bracket includes a circular hoop that is axially interference-fitted with the end of the corresponding main air duct. The bottom of the circular hoop is radially symmetrically connected to two diagonal braces forming an inverted V-shaped structure. Each diagonal brace has a horizontally set foot block fixed to its bottom end. The foot block is connected to the bottom surface of the box groove by a matching bolt.

[0009] As a preferred technical solution of this utility model, the bottom opening of the air outlet is connected to an inverted isosceles trapezoidal air knife.

[0010] As a preferred embodiment of this utility model, the top edge of the groove opening of the box is higher than the top of the branch duct.

[0011] The beneficial effects of this utility model are: 1. This invention effectively avoids friction between the aluminum rod and the equipment, extending the equipment's service life. The equipment adopts an open design, with the water-blowing assembly suspended directly below the aluminum rod, unlike existing technologies that use a closed cavity. The aluminum rod passes through U-shaped openings at both ends of the slot and is supported by guide wheels, continuously passing through the slot and only contacting the guide wheels, without direct contact with any part of the water-blowing assembly. Because there is no physical contact between the aluminum rod and the water-blowing assembly, wear and tear caused by friction is prevented. This improves the durability of the drying equipment, reduces maintenance requirements, and extends its overall service life.

[0012] 2. This invention improves drying efficiency and uniformity, ensuring the surface treatment quality of the aluminum rod. In the water-blowing assembly, the blower supplies air to the main air duct through the air inlet pipe, and the airflow continuously blows out from multiple air outlets through the branch air ducts. The multiple air outlets are arranged side-by-side, forming a continuous and uniform air curtain covering the aluminum rod surface, effectively blowing away moisture, oil, and oxide scale. The downward-sloping design allows the airflow to directly impact the aluminum rod surface, enhancing the blowing force and preventing moisture residue.

[0013] 3. This invention enables centralized water collection, improving the workshop environment and reducing subsequent processing. The trough is positioned on the top surface of the support platform; as the aluminum rod passes through it, the blown-off water drips or splashes directly into the trough. The U-shaped openings at both ends of the trough allow the aluminum rod to pass through while effectively limiting water overflow. Water, oil, and other impurities that fall during the drying process are trapped within the trough, preventing them from falling onto the workshop floor; this avoids slippery and contaminated floors, improves the working environment, and reduces cleaning and maintenance workload. The trough can also serve as a temporary water collection container for convenient subsequent centralized treatment or discharge. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0017] Example To address the technical problems in the background section, a drying device for producing linear aluminum conductors is provided as follows: Combination Figures 1-5As shown, a drying device for producing linear aluminum conductors includes a support platform 1. The top surface of the support platform 1 is provided with a trough 2. The two ends of the trough 2 are vertically and symmetrically provided with U-shaped openings 21. The bottom sides of the outer surface of the U-shaped openings 21 are vertically and symmetrically connected with lugs 41. The two lugs 41 are rotatably supported by guide wheels 4. The aluminum rod 8 to be dried is continuously supported by the two guide wheels 4. A water blowing assembly 3 is provided on the bottom surface of the trough 2. The water blowing assembly 3 includes a main air duct 31 suspended parallel to the aluminum rod 8 directly below it. Both ends of the main air duct 31 are fixedly supported by brackets 35 fixed to the bottom surface of the box trough 2. An L-shaped air inlet duct 32 is connected to the middle of the bottom surface of the main air duct 31. The horizontal part of the air inlet duct 32 passes through the corresponding side of the box trough 2 and is connected to the air outlet of the blower 6 suspended on the corresponding outer side of the box trough 2. Multiple branch air ducts 33 are symmetrically connected at equal intervals on both sides of the main air duct 31 along the direction of the aluminum rod 8. The top opening of the branch air duct 33 is detachably connected to an air outlet 34, and the air outlet 34 is tilted downward and radially aligned with the aluminum rod 8.

[0018] In the above technical solution, the drying equipment effectively avoids friction between the aluminum rod 8 and the equipment, extending its service life. The equipment adopts an open design, with the water-blowing assembly 3 suspended directly below the aluminum rod 8, unlike the closed cavity used in existing technologies. The aluminum rod 8 passes through the U-shaped openings 21 at both ends of the slot 2 and is supported by the guide wheels 4. As it continuously passes through the slot 2, it only contacts the guide wheels 4 and does not directly contact any part of the water-blowing assembly 3. Because there is no physical contact between the aluminum rod 8 and the water-blowing assembly 3, wear caused by friction is prevented. This improves the durability of the drying equipment, reduces maintenance requirements, and extends its overall service life.

[0019] This drying equipment improves drying efficiency and uniformity, ensuring the surface treatment quality of the aluminum rod 8. In the water-blowing assembly 3, the blower 6 supplies air to the main air duct 31 through the air inlet duct 32, and the airflow is continuously blown out from multiple air outlets 34 through the branch air ducts 33. The multiple air outlets 34 are arranged side-by-side, forming a continuous and uniform air curtain covering the surface of the aluminum rod 8, effectively blowing away moisture, oil, and oxide scale. The downward-sloping design allows the airflow to directly impact the surface of the aluminum rod 8, enhancing the blowing force and preventing moisture residue.

[0020] This drying equipment enables centralized water collection, improving the workshop environment and reducing subsequent processing. The trough 2 is located on the top surface of the support platform 1. When the aluminum rod 8 passes through the trough 2, the blown-off water drips or splashes directly into the trough 2. The U-shaped openings 21 at both ends of the trough 2 allow the aluminum rod 8 to pass through while effectively limiting water overflow. Water, oil, and other impurities that fall off during the drying process are trapped inside the trough 2 and will not be blown onto the workshop floor; this avoids slippery and contaminated workshop floors, improves the working environment, and reduces cleaning and maintenance workload. The trough 2 can also serve as a temporary water collection container for convenient subsequent centralized treatment or discharge.

[0021] like Figures 1-3 As shown, the support platform 1 includes a bracket 11 that is interference-fitted with the bottom of the box groove 2. Angle steel legs 12 are vertically and symmetrically connected to the four corners of the bottom surface of the bracket 11, and the bottom ends of the four angle steel legs 12 are vertically connected to a pad 13.

[0022] like Figure 2 and Figure 3 As shown, a straight water pipe 22 is vertically connected to a corner of the bottom surface of the tank 2, and the straight water pipe 22 passes through the bottom surface of the support 11 with a gap. The bottom end of the water support 11 is detachably connected to a water bend 23, and the bottom opening of the water bend 23 is aligned with the opening of the water receiving trough 7 placed on the top surface of the pad 13.

[0023] In the above technical solution, the support platform 1 adopts a modular design, consisting of a bracket 11, angle steel legs 12, and a base plate 13. The tank 2 is interlocked with the bracket 11 via an interference fit. Simultaneously, a straight water pipe 22 is installed at the bottom of the tank 2, and water flow is guided to the water receiving trough 7 placed on the base plate 13 via a water bend 23. The tank 2 and the bracket 11 of the support platform 1 are detachably interlocked, which allows the tank 2 to be easily lifted as a whole when cleaning accumulated impurities inside, simplifying maintenance operations.

[0024] The straight water inlet pipe 22 and the bend in the water inlet pipe 23 constitute an organized drainage system. The mixture of water and oil that is blown down and accumulated in the tank 2 can be centrally and controllably guided into the water receiving tank 7 through this system, which prevents the liquid from overflowing in the tank and further ensures the dryness and cleanliness of the workshop floor, and realizes centralized management of waste liquid.

[0025] like Figure 1 and Figure 2 As shown, a pair of protrusions 51 are vertically and symmetrically connected to the top inner sides of the two U-shaped openings 21. Each protrusion 51 is longitudinally rotatably connected to the bottom surface of the U-shaped opening 21 with a guide roller 5. The gap between the two pairs of guide rollers 5 passes through the aluminum rod 8.

[0026] In the above technical solution, two pairs of rotatable guide rollers 5 are added to the inner top of the U-shaped openings 21 at both ends of the trough 2, forming a channel together with the bottom guide support wheels 4. The guide rollers 5 form a constraint from above the aluminum rod 8, cooperating with the guide support wheels 4 below to restrict the displacement of the aluminum rod 8 in the vertical and lateral directions; ensuring that the aluminum rod 8 is always on a preset, stable central path when passing through the drying area. Even if the aluminum rod 8 has a slight tendency to bounce up and down during its movement, it will be guided by the rotatable guide rollers 5, converting sliding friction into rolling friction, effectively preventing the aluminum rod 8 from scratching the edge of the U-shaped opening 21 or the trough 2 itself, thus protecting both the surface of the aluminum rod 8 and the equipment.

[0027] like Figure 4 and Figure 5 As shown, the bracket 35 includes a circular hoop 351 that is axially interference-fitted with the end of the corresponding main air duct 31. The bottom of the circular hoop 351 is radially symmetrically connected to two diagonal bracing rods 352 that form an inverted V-shaped structure. The bottom end of each diagonal bracing rod 352 is fixed with a horizontally arranged foot block 353. The foot block 353 is connected to the bottom surface of the box groove 2 by a matching bolt.

[0028] In the above technical solution, the bracket 35 adopts a composite structure consisting of a circular hoop 351, an inverted V-shaped diagonal brace 352, and a foot block 353, and is fixed to the inner bottom surface of the box groove 2 by bolts. The inverted V-shaped structure has mechanical stability, which can effectively resist the airflow reaction force from the main air duct 31 and multiple branch air ducts 33 as well as the vibration generated by the operation of the equipment, preventing the water blowing assembly 3 from shaking or shifting during operation, ensuring that the relative position between the air outlet 34 and the aluminum rod 8 is constant, thereby ensuring the stability of the drying effect. The interference fit between the circular hoop 351 and the end of the main air duct 31 provides a firm clamping fixation, while the bolt connection at the bottom facilitates fine adjustment of the position of the bracket 35 and even the entire water blowing assembly 3 during installation, ensuring its alignment with the aluminum rod.

[0029] like Figure 4 and Figure 5 As shown, the bottom opening of the air outlet 34 is connected to an inverted isosceles trapezoidal air knife 341.

[0030] In the above technical solution, the core function of the air knife 341 is to gather and accelerate the relatively divergent airflow delivered by the air outlet 34 into a narrow, uniform, high-speed linear air curtain. This air-gathering effect makes the airflow impact force stronger and the energy more concentrated, which can more effectively cut and blow away the water film attached to the surface of the aluminum rod 8, thereby improving the drying efficiency and cleanliness of the unit airflow.

[0031] like Figure 1 As shown, the top edge of the slot opening of the box trough 2 is higher than the top of the branch duct 33.

[0032] In the above technical solution, the edge of the trough 2 is higher than the highest point of all the internal branch air ducts 33, and this height difference forms a protective dike. When the high-speed airflow blows towards the aluminum rod, some droplets will inevitably splash. The higher sidewall of the trough 2 can successfully intercept these splashing water droplets and impurities, preventing them from splashing over the trough into the external environment and keeping the working area clean.

[0033] Working principle and usage process of this utility model: When using this utility model, firstly, the operator connects the blower 6 to the power supply and ensures that the water tank 7 is properly placed on the pad 13, and that the outlet of the water inlet bend 23 is directly connected to the opening of the water tank 7.

[0034] Once preparations are complete, the production line is started. The aluminum rods 8, awaiting drying, begin to move along their axial direction under the drive of the external traction device. The aluminum rods 8 first approach the tank 2 from one end of the equipment. Before entering the tank 2, the aluminum rods 8 pass through a guide channel formed by a U-shaped opening 21, guide wheels 4, and guide rollers 5. Specifically, the aluminum rods 8 are supported by two guide wheels 4 rolling from the bottom, while they are constrained and guided by two pairs of guide rollers 5 from the top and sides.

[0035] As the aluminum rod 8 passes through the slot 2, the drying process starts simultaneously. The high-speed airflow generated by the blower 6 is delivered to the main air duct 31 via the air inlet duct 32. The airflow is distributed axially within the main air duct 31 and then branched to multiple branch air ducts 33 that are symmetrically connected at equal intervals on both sides. The air outlet 34 at the top of each branch air duct 33 directs the airflow, which is further concentrated and accelerated by the air knife 341 connected to its bottom opening, forming a series of strong, concentrated linear air curtains. These air knives 341 are set to be tilted downwards and radially aligned with the aluminum rod 8 passing above them.

[0036] High-speed airflow continuously impacts the lower surface and sides of the aluminum rod 8, efficiently blowing away and peeling off moisture, oil, and other impurities adhering to the surface of the aluminum rod 8. Because multiple air nozzles 34 and air knives 341 are continuously arranged along the traveling direction of the aluminum rod 8, an air curtain area is formed to continuously and uniformly blow on the surface of the aluminum rod 8, effectively ensuring thorough drying.

[0037] The blown-off moisture and impurities naturally drip or splash downwards under the influence of gravity and airflow. Since the top edge of the tank 2 is higher than the top of the branch duct 33, it forms an effective protective dike, reliably intercepting all splashed liquid and impurities inside the tank 2. Waste liquid collected at the bottom of the tank 2 is guided to the receiving tank 7 for centralized collection via the straight water pipe 22 and the bend in the water pipe 23, facilitating subsequent treatment.

[0038] Finally, the dried and cleaned aluminum rod 8 is smoothly delivered from the guide channel at the other end of the box trough 2 and directly enters the subsequent extrusion process.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
