Description

Technical Field

[0001] This utility model relates to the field of feeding and distributing technology, specifically a feeding device for a spiral separator. Background Technology

[0002] Spiral separators are widely used material sorting equipment in mining, metallurgy, and environmental protection fields, primarily for separating materials based on their density, particle size, and other characteristics. Traditional spiral separators often suffer from low sorting efficiency, incomplete separation of waste and qualified materials, and susceptibility to clogging. Especially when sorting materials containing light impurities (such as waste and dust), conventional equipment struggles to achieve efficient coordination between pneumatic separation and mechanical conveying, resulting in poor sorting performance. Furthermore, material residue easily remains on the conveyor belt, affecting the stability and hygiene of continuous operation. In addition, the discharge section of existing sorting devices often lacks effective material guidance and collection mechanisms, easily leading to material accumulation or spillage, increasing the difficulty of subsequent processing.

[0003] Therefore, there is an urgent need for a material distribution device for spiral separators that can improve sorting efficiency, ensure sorting quality, facilitate cleaning and maintenance, and has a reasonable structure. Utility Model Content

[0014] 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.

[0015] Example: Please refer to Figure 1-3A material distribution device for a spiral separator includes a material distribution box 1 and a conveying track 5 located at the bottom of the material distribution box 1. The conveying track 5 has a discharge chute 6 on its lower side. The top of the material distribution box 1 has a feed inlet 2. The inner wall of the material distribution box 1 has a first branch pipe 17 and a second branch pipe 18 arranged in a herringbone pattern. One end of the first branch pipe 17 has a waste pipe 3. The top of the material distribution box 1 has a blower 4. The output end of the blower 4 is located on the inner wall of the feed inlet 2 and above the first branch pipe 17 and the second branch pipe 18. The inner wall of the conveying track 5 has a conveyor belt 20 located at the bottom of the material distribution box 1. A cleaning brush 13 is located on the upper side of the conveyor belt 20.

[0016] The distribution box 1 is the main body and separation chamber of the entire device. Its interior is designed as a closed or semi-closed space to control the airflow direction. The feed inlet 2, located at the top of the distribution box, receives the mixed materials conveyed from the upstream spiral separator. The herringbone-shaped arrangement of the first and second branch pipes 17 and 18 is a key structure for material separation. The "herringbone" arrangement means that the two pipes are close to the feed inlet and the blower at the top, then separate downwards and outwards at an angle. This design effectively guides the airflow and material in two different directions. Typically, the first branch pipe connects to the waste pipe to discharge light waste, while the second branch pipe allows qualified materials to pass through and fall onto the conveyor belt. This structure utilizes a combination of gravity and airflow for separation. The blower provides a horizontal or slightly downward-sloping airflow. Its function is not to blow away the material, but to "air-sort" the falling material. The conveyor belt is used to receive and horizontally transport qualified materials falling from the second branch pipe. The cleaning brush is an important improvement. It is set to be able to contact the surface of the conveyor belt to remove dust and fine particles adhering to the conveyor belt, prevent belt slippage and deviation, and reduce cross-contamination and dust caused by material residue, thus maintaining a clean production environment.

[0017] Waste slag pipe 3 penetrates the inner wall of the distribution box 1 and is connected to the interior of the first branch pipe 17. The output end of the blower 4 is provided with a protective net 19, which is located inside the distribution box 1.

[0018] Among them, the protective net 16 is crucial for the blower 4, as it prevents falling lumpy materials from entering the blower and causing damage or blockage to the blower blades, thus ensuring the safe operation of the equipment. The waste residue pipe 3, as an extension of the first branch pipe, guides lightweight waste residue to a dedicated collection container or subsequent treatment system.

[0019] The inner wall of the conveying track 5 is provided with a pair of conveying rollers 21, and the conveying rollers 21 are rotatably connected to the inner wall of the conveying track 5. The conveyor belt 20 is installed on the outside of the conveying rollers 21. The outer side of the conveying track 5 is provided with a motor bracket 8, and a conveying motor 9 is installed inside the motor bracket 8. The output end of the conveying motor 9 is fixedly connected to one end of the conveying rollers 21.

[0020] The conveyor roller 21 and the conveyor motor 9 describe the driving method of the conveyor belt. The motor drives the conveyor roller to rotate, thereby driving the conveyor belt to perform stable cyclical motion and realizing automated continuous material conveying.

[0021] The bottom of the conveying track 5 is provided with a support column 7, and the support column 7 is located at one end of the conveying track 5. A triangular bracket 14 is installed at the connection between the conveying track 5 and the discharge trough 6. The discharge end of the conveying track 5 is provided with an inclined plate 23, and the inclined plate 23 is located on the inner wall of the discharge trough 6.

[0022] The support column 7 and the triangular bracket 14 provide the mechanical stability and structural strength of the entire device, ensuring that the conveyor track will not deform under load. The inclined plate 23 is installed on the inner wall of the discharge chute, and its function is to smoothly guide the material falling from the end of the conveyor belt, so that it falls in a concentrated manner and reduces impact and splashing.

[0023] A mounting bracket 15 is installed at one end of the discharge trough 6, and an electric push rod 16 is provided inside the mounting bracket 15. The output end of the electric push rod 16 passes through the inner wall of the discharge trough 6. A push plate 22 is provided at the output end of the electric push rod 16, and the push plate 22 is slidably connected to the inner wall of the discharge trough 6. The push plate 22 is located on the lower side of the inclined plate 23.

[0024] Among them, the electric push rod 16 and the push plate 22 are an automatic unloading or sorting collection mechanism. The electric push rod periodically or continuously pushes the push plate to slide in the discharge trough, which can push the material accumulated in the discharge trough into the designated collection bin, avoiding material accumulation and blockage. If the discharge trough is divided into multiple compartments by the partition, the push plate can push the material into different compartments in sequence to achieve batch collection based on time or output.

[0025] A support frame 10 is provided on the upper side of the conveying track 5, and a pneumatic cylinder 11 is installed on the upper side of the support frame 10. A movable plate 12 is installed at the output end of the pneumatic cylinder 11, and both ends of the movable plate 12 are slidably connected to the inner wall of the support frame 10. A cleaning brush 13 is installed on the lower side of the movable plate 12.

[0026] The support frame 10, pneumatic cylinder 11, and movable plate 12 enable the cleaning brush to move up and down, rather than being fixed. The pneumatic cylinder pushes the movable plate downward, pressing the cleaning brush against the conveyor belt surface to improve cleaning efficiency. The pneumatic cylinder also lifts the movable plate and cleaning brush, separating them from the conveyor belt for easy unloaded operation or brush replacement and maintenance.

[0027] Working Principle: The mixed material from the spiral separator enters the distribution box 1 through the feed inlet 2. The material falls naturally under gravity. During this fall, the blower 4 starts, generating a controllable airflow that passes through the falling material layer. Low-density, lightweight waste (such as sawdust, paper scraps, and plastic film) is blown into the first branch pipe 17 by the force of the airflow, exceeding its own weight. It is then discharged through the waste pipe 3 and enters the waste collection system. High-density, heavy qualified materials (such as metal particles and heavy minerals) have sufficient weight to overcome the airflow's thrust and continue falling vertically through the channel of the second branch pipe 18. The qualified material, after air separation, falls onto the conveyor belt 20. The conveyor motor 9 drives the conveyor belt 20 to horizontally transport the material to the discharge chute 6 at the end of the device. The material slides into the discharge chute 6 through the inclined plate 23 at the end of the conveyor belt. The electric push rod 16 operates according to a set program, pushing the push plate 22 to push the material in the discharge chute into the designated collection container, realizing automated and batch collection. Throughout the conveying process, the pneumatic cylinder 11 presses down the moving plate 12, causing the cleaning brush 13 mounted on it to adhere closely to the surface of the conveyor belt. As the conveyor belt moves, the cleaning brush continuously scrapes, removing residual dust and fine particles adhering to the belt surface, keeping the conveyor belt clean, and ensuring stable and efficient operation of the equipment.

[0028] This material sorting device integrates air separation, conveying, cleaning and automatic unloading functions through ingenious structural design. It effectively solves problems such as incomplete separation of light waste residue, easy dirt on the conveyor belt and need for manual intervention in unloading in spiral separators. It significantly improves sorting efficiency and automation level and is suitable for industrial applications that require fine sorting.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
