Description

Technical Field

[0001] This utility model belongs to the field of powder recycling technology, specifically a waste powder recycling system. Background Technology

[0002] In industrial powder coating processes (such as electrostatic spraying and powder metallurgy), to improve material utilization and reduce production costs, the waste powder scattered during the powder coating process is usually recycled and reused. Currently, the industry commonly uses powder recovery towers to recover powder. Among them, the core equipment of the powder recovery tower mainly uses a cyclone separator as the core equipment for waste powder recovery. It uses the centrifugal force generated by high-speed airflow to separate the powder from the air and collect the powder in a recovery bin at the bottom.

[0003] However, in continuous, high-volume powder spraying operations, the amount of scattered powder is enormous, while the physical volume of the recycling bin is limited. This causes the recycling bin to fill up in a short time. Once the recycling bin is full, the production line must be stopped, and the recycling bin must be manually disassembled, the powder poured out, and reinstalled before the system can resume operation. Frequent shutdowns not only significantly reduce the continuous operating time of the equipment but also increase the cost of manual intervention, severely restricting overall production efficiency. Utility Model Content

[0004] This invention provides a waste powder recycling system to address the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A waste powder recycling system includes a powder recycling tower, which includes a cyclone separator and a receiving box located below the cyclone separator and communicating with the discharge port of the cyclone separator. A circular shaft is longitudinally arranged inside the receiving box. One end of the circular shaft passes through the receiving box and is coaxially and fixedly connected to the rotating shaft of a fixedly installed motor. The motor is controlled by a timer and rotates at the same angle each time. Several baffles are evenly arranged along the circumference of the circular shaft. Adjacent baffles form a receiving groove. The front and rear end faces of the baffles are in contact with the front and rear inner walls of the receiving box. The lower part of the receiving box has a discharge port opposite to the receiving groove, and a receiving bucket is located below the discharge port.

[0007] In use, the dust collected by the cyclone separator falls into the receiving box, where it settles into a receiving trough formed between two baffles. After a period of time, a timer controls a motor to rotate the receiving trough at a certain angle, aligning the opening of the next receiving trough with the discharge port of the cyclone separator, allowing for continued dust collection. The rotation of the baffles moves the dust, which is then pushed to the discharge port and into the receiving bucket. When the receiving bucket is full, the dust can be directly poured into the desired accumulation location without stopping the cyclone separator, thus ensuring overall production efficiency.

[0008] Preferably, a feeding hopper is fixedly installed on the upper part of the receiving box. The feeding hopper is wider at the top and narrower at the bottom, and its two sides are located on the same inclined plane as the corresponding side baffles. The lower part of the feeding hopper has an upwardly convex arc-shaped structure, and its lower end face fits against the outer end face of the baffle. The feeding hopper can play a guiding role, ensuring that the material can accurately enter the receiving trough.

[0009] Preferably, the discharge port is located on the bottom surface of the receiving box, and a limiting block is fixedly connected to the lower right side of the receiving box. The top surface of the limiting block is arc-shaped and fits against the end face of the baffle. The discharge port being on the bottom surface of the receiving box allows for better material discharge, while the limiting block ensures that the powder moves to the discharge port within its limits.

[0010] Preferably, the front side of the receiving box is inlaid with a circular transparent plate, and the extension line of the circular shaft passes through the center of the circle containing the transparent plate. The transparent plate allows observation of the amount of material in the receiving trough, so that the motor can be started in advance to rotate if the trough is full before the predetermined time has elapsed, thus avoiding excessive powder accumulation.

[0011] Preferably, the baffle includes a rotating plate and a scraper extending forward from the front of the rotating plate. The scraper contacts and cooperates with the transparent plate, and the scraper can scrape the transparent plate to ensure that the transparent plate is clean and facilitate the staff to observe the receiving trough.

[0012] The beneficial effects of this utility model are as follows: The use of this application can utilize a motor to drive the rotating shaft, thereby driving the baffle to rotate and realize the rotation of the receiving trough. This ensures that the receiving trough moves the powder to the discharge port and falls into the receiving bucket after a certain period of time, so that the powder can be recovered without stopping the machine, thus ensuring the overall production efficiency.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] A waste powder recycling system, such as Figure 1 As shown. It includes a powder recovery tower, which comprises a cyclone separator 1 and a receiving box 2 located below the cyclone separator 1. The top surface of the receiving box 2 is vertically connected to and communicates with a discharge pipe 8. The upper end of the discharge pipe 8 is fixedly connected to and communicates with the discharge port of the cyclone separator 1. A circular shaft 4 is longitudinally arranged inside the receiving box 2. One end of the circular shaft 4 extends out of the receiving box 2 and is coaxially connected to and fixedly connected to the rotating shaft of a fixedly installed motor. The motor is controlled by a timer and rotates at the same angle each time. Several baffles 5 are evenly arranged along the circumference of the circular shaft 4. Adjacent baffles 5 form a receiving groove 9. The front and rear end faces of the baffles 5 are in contact with the front and rear inner walls of the receiving box 2. The lower part of the receiving box 2 has a discharge port opposite to the receiving groove 9, and a receiving bucket 3 is located below the discharge port.

[0019] In use, the dust collected by the cyclone separator 1 falls into the receiving box 2. After entering the receiving box 2, the dust falls into the receiving trough 9 formed between the two baffles 5. After receiving the dust for a period of time, the timer controls the motor to rotate the receiving trough 9 by a certain angle, so that the opening of the next receiving trough 9 is opposite to the discharge port of the cyclone separator 1, and the dust continues to be received. When the baffles 5 rotate, they drive the dust to move, and the dust can be pushed by the baffles 5 to the discharge port, and then enter the receiving bucket 3. When the receiving bucket 3 is full, the dust can be directly poured into the place where it is to be piled up, and there is no need to stop the cyclone separator 1, thus ensuring the overall production efficiency.

[0020] The receiving box 2 is fixedly equipped with a feeding hopper 6 at its upper part. The feeding hopper 6 is wider at the top and narrower at the bottom, and its two sides are located on the same inclined plane as the corresponding side baffles 5. The lower part of the feeding hopper 6 has an upwardly convex arc-shaped structure, and its lower end face is in contact with the outer end face of the baffle 5. The feeding hopper 6 can play a guiding role, ensuring that the material can accurately enter the receiving trough 9.

[0021] The discharge port is located on the bottom surface of the receiving box 2, and a limiting block 7 is fixedly connected to the lower right side of the receiving box 2. The top surface of the limiting block 7 is arc-shaped and fits against the end face of the baffle 5. The discharge port being on the bottom surface of the receiving box 2 allows for better material discharge, while the limiting block 7 ensures that the powder moves to the discharge port under the constraint of the limiting block 7.

[0022] The front side of the receiving box 2 is inlaid with a circular transparent plate 10, and the extension line of the circular shaft 4 passes through the center of the circle containing the transparent plate 10. The transparent plate 10 allows observation of the amount of material in the receiving trough 9, so that the motor can be started in advance to avoid excessive powder accumulation if the trough is full before the predetermined time.

[0023] The baffle 5 includes a rotating plate and a scraper extending forward from the front of the rotating plate. The scraper contacts and cooperates with the transparent plate 10, and the scraper can scrape the transparent plate 10 to ensure that the transparent plate 10 is clean and facilitate the staff to observe the receiving trough 9.

[0024] The use of this application allows the motor to drive the circular shaft 4 to rotate, thereby driving the baffle 5 to rotate, realizing the rotation of the receiving trough 9. This ensures that the receiving trough 9 moves the powder to the discharge port and falls into the receiving bucket 3 after a certain period of time, so that the powder can be recovered without stopping the machine, thus ensuring the overall production efficiency.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
