Description

Technical Field

[0001] This utility model specifically relates to a drying and screening device for water-quenched alloys, belonging to the field of water-quenched alloy processing technology. Background Technology

[0002] In the field of metal processing, the drying and screening of water-quenched alloys is a critical step affecting product quality. Traditional equipment often uses separate drying and screening devices, which suffer from drawbacks such as fragmented process flow, high energy consumption, and large footprint. Although existing drum screens can achieve continuous operation, the static drying method results in insufficient contact between hot air and materials, easily leading to surface crusting and internal dampness. During screening, due to the adhesive properties of alloy particles, screen hole clogging is frequent, requiring machine shutdown for manual cleaning, which seriously affects the continuity of the production line. Material classification and collection systems generally adopt a single outlet structure, resulting in the mixing of alloys of different particle sizes, making it difficult to meet the classification requirements of precision casting for raw material particle size. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel drying and screening device for water-quenched alloys, thereby achieving rapid drying and screening of water-quenched alloys.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drying and screening device for water-quenched alloys includes a drying support placed on the ground or a table. A limiting groove is formed in the inner wall of the drying support. An annular connecting block is fixedly engaged inside the limiting groove. A rapid drying and screening component for drying and screening water-quenched alloys is installed on the inner wall of the annular connecting block. A drying component is fixedly installed on the top of the drying support. A first discharge port and a second discharge port are formed at the bottom of the drying support. The first discharge port is located upstream of the second discharge port.

[0005] The rapid drying and screening assembly includes a rotating motor for driving and a screening cylinder for screening. The rotating motor is fixedly installed on one side of the drying support, and both ends of the screening cylinder are respectively engaged and fixed to the inner wall of an annular connecting block. Screening holes are provided on the outer side of the screening cylinder, and a connecting pipe passes through the center of the screening cylinder along its axis. The connecting pipe is rotatably connected to the screening cylinder, and a spiral conveying blade is welded to the inner surface of the connecting pipe. A flow-guiding cavity is formed inside the connecting pipe and the spiral conveying blade, and an air outlet is provided on the spiral conveying blade.

[0006] One end of the connecting pipe is connected to the drying component via a pipe, and a second gear is provided on the outside of the connecting pipe. The second gear meshes with a first gear fixed on the output shaft of the rotating motor.

[0007] The drying unit consists of an induced draft fan, a heating chamber, heating wires, and an air outlet pipe. The induced draft fan can introduce outside air into the heating chamber, and then the heating wires are used to heat the air inside the heating chamber. Finally, the hot air flow inside the heating chamber flows into the rapid drying screening component through the air outlet pipe, thereby enabling the water-quenched alloy to be dried.

[0008] The screening cylinder has a feed inlet at one end and a notch at the bottom on the other side, which is connected to the second discharge outlet.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model adopts a linkage structure of a screening cylinder with screening holes and an internal spiral conveying blade, combined with the meshing transmission of gear one and gear two. While the spiral conveying blade rotates and conveys, the material is screened through the screening holes, realizing synchronous operation of screening and conveying, improving processing efficiency. At the same time, a guide cavity and an air outlet of the conveying blade are set up so that the hot air flow generated by the drying component can penetrate the material layer for three-dimensional drying, and the stirring of the spiral conveying blade enhances the drying effect. 2. This utility model achieves graded collection of water-quenched alloys through a first and second discharge port with layered arrangement, meeting the separation requirements of products with different particle sizes, and the overall structure has a high degree of integration.

[0012] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be noted that these embodiments are only for explaining this utility model and do not limit the scope of protection.

[0013] 1. Overall Structure Description ( Figure 1-3 ) Drying support 1: Fixed to the ground, with an annular limiting groove on its inner wall for engaging the annular connecting block 2. The bottom of the support has a first discharge port 5 and a second discharge port 6, wherein the first discharge port 5 is located upstream (near the feed end) in the material flow direction, and the second discharge port 6 is located downstream.

[0014] Annular connecting block 2: It is fixed to the inner wall of the drying bracket 1 through the limiting groove and is used to support the screening component 3.

[0015] Drying component 4: Installed on top of drying bracket 1, it consists of an exhaust fan, a heating box, an electric heating wire, and an air outlet duct. Working process: The exhaust fan draws in air → the electric heating wire heats the air (temperature range 80-120℃) → the hot air is delivered to the connecting pipe 305 through the air outlet duct.

[0016] 2. Structure and connection of the rapid drying screening component 3 ( Figure 4 ) Rotary motor 301: fixed to the side of drying bracket 1, with gear 302 mounted on the output shaft.

[0017] Screening cylinder 303: Both ends are fixed by annular connecting blocks 2. Screening holes 304 are evenly opened on the cylinder wall (the hole diameter is customized according to the alloy particle size). One end is provided with a feed inlet, and the bottom of the other end is provided with a notch that connects to the second discharge port 6.

[0018] Connecting pipe 305: runs along the axis of the screening cylinder and is rotatably connected to the screening cylinder 303 via a bearing. Gear 2 306 is installed on its outer side and meshes with gear 1 302; one end of the outer side is connected to the air outlet pipe of the drying component 4 via a pipe.

[0019] Spiral conveyor blade 307: welded to one end of the connecting pipe 305 and rotates synchronously with the connecting pipe. A flow guide cavity is opened inside the blade and the connecting pipe, and air outlets 308 are evenly distributed on the surface of the blade.

[0020] 3. Work Process ① Feeding and conveying: Water-quenched alloy is fed into the 303 feed inlet of the screening cylinder; The rotating motor 301 drives gear 1 302 → gear 2 306, which in turn drives the connecting pipe 305 and the spiral conveying blades 307 to rotate, pushing the material towards the discharge end.

[0021] ② Simultaneous drying and sieving: Drying: The hot air generated by the drying unit 4 is guided into the inner cavity through the connecting pipe 305 and sprayed out from the air outlet 308 of the spiral blade, penetrating the material layer to achieve three-dimensional heating; Screening: Small-diameter alloy particles fall through the screening hole 304 into the bottom of the drying support 1 and are discharged through the first discharge port 5; large-diameter alloy particles are pushed to the end of the screening cylinder by the spiral blades and fall into the second discharge port 6 through the bottom notch.

[0022] The above embodiments are only for clearly illustrating the technical solution of this utility model. Any structural changes based on the same principle (such as the tilt angle adjustment of the screening cylinder, the adaptive control of hot air temperature, etc.) shall fall within the protection scope of the claims of this utility model.
