Description

Technical Field

[0001] This utility model relates to the field of powder conveying equipment technology, and in particular to a powder airlock and flow stabilization device. Background Technology

[0002] In powder material conveying systems, airlocking and flow stabilization are crucial. This mainly refers to preventing unnecessary exchange between the powder and the outside air during the conveying process, thus avoiding moisture, oxidation, or contamination of the powder. It also ensures that the powder maintains a stable flow rate during conveying, avoiding sudden fluctuations, thereby guaranteeing the stability of subsequent processes and product quality.

[0003] A powder airlock and flow stabilizing device, application number CN201821305842.8, includes a feeding hopper, a rotary feeding system, a connector, and a conveying pipe. The feeding hopper has a feed inlet and a cleaning inlet at its top, an objective lens on its side wall, and a cleaning door at its bottom. The rotary feeding system includes a first rotary feeder and a second rotary feeder. The first rotary feeder consists of a first housing and a first impeller, which is connected to a first power system via a first chain. The second rotary feeder consists of a second housing and a second impeller, which is connected to a second power system via a second chain. A conveying pipe is located below the second rotary feeder. This invention solves the problem of airflow blockage during powder material feeding and conveying by setting up dual rotary feeders, resulting in more uniform feeding and reducing the impact and wear of powder on the internal structure of the conveying pipe, thus extending the service life of the equipment. However, powder can adhere to the surface of the blades during the conveying process, which reduces the conveying efficiency and affects the service life. Furthermore, during feeding, the powder may accumulate in the feed hopper and be difficult to fall, thus affecting the feeding speed and conveying efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a powder airlock and flow stabilization device.

[0005] An embodiment of this utility model provides a powder airlock and flow stabilization device, comprising:

[0006] Two upright frames are provided, with a screw conveyor fixedly installed between them. A feeding hopper is fixedly connected to the feed inlet of the screw conveyor. Two rotating rods are rotatably connected to the inner wall of the feeding hopper, and multiple distributing blades are fixedly connected to each of the two rotating rods. Two scraping components are installed on the inner wall of the feeding hopper, each including two annular guide grooves on the inner wall. Sliding grooves are formed on both sides of each of the multiple distributing blades, and scrapers are slidably connected within each of the multiple sliding grooves. Each scraper slides within the two annular guide grooves. A servo motor is fixedly installed on the side wall of the feeding hopper, with its rotating end fixedly connected to one of the rotating rods. Two sprockets are rotatably connected to the side wall of the feeding hopper, and the two sprockets are driven by a chain. Each of the two sprockets is fixedly connected to one of the rotating rods. A material feeding component is installed on the feeding hopper, and a funnel is connected to the upper surface of the feeding hopper.

[0007] Furthermore, the material feeding assembly includes a vertical plate fixedly connected to the upper end face of the feeding bin, a plurality of springs fixedly connected to the side wall of the vertical plate, a connecting plate fixedly connected between the plurality of springs, a plurality of connecting rods fixedly connected to the connecting plate, the plurality of connecting rods slidingly penetrating the feeding bin, a plurality of fixing plates fixedly connected between the plurality of connecting rods, a toggle plate fixedly connected between the plurality of connecting rods, and a plurality of toggle levers fixedly connected to the upper end face of the plurality of fixing plates and the toggle plate.

[0008] Furthermore, two support frames are fixedly connected to the upper end face of the screw conveyor, and both support frames are fixedly connected to the side wall of the discharge hopper.

[0009] Furthermore, a protective shell is fixedly connected to the side wall of the feeding hopper, and the protective shell is matched with the servo motor.

[0010] Furthermore, an observation window is installed on the feeding hopper.

[0011] Furthermore, both of the lower end faces of the uprights are provided with anti-slip textures.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the rotating rod rotates, the distributing blades begin to rotate, and the scraper slides along the annular guide groove. At the same time, the scraper moves along the sliding groove to scrape off the powder on the surface of the distributing blades, thus preventing the powder from adhering to the surface of the distributing blades and ensuring the conveying efficiency of the distributing blades.

[0014] 2. When the dispensing blades rotate, they will continuously contact the actuating plate. Under the limit of the spring, the actuating rod will reciprocate, which can prevent the powder from accumulating in the funnel, facilitate the feeding, and ensure that the powder feeding speed is more uniform.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a powder airlock and flow stabilization device, comprising:

[0021] Two uprights 1 are provided with anti-slip textures on the lower end face of both uprights 1 to improve the stability of the device. A screw conveyor 2 is fixedly installed between the two uprights 1. The screw conveyor 2 is existing technology and is a device that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. It will not be described in detail here. The feed inlet of the screw conveyor 2 is fixedly connected to the discharge bin 3. The discharge bin 3 is equipped with an observation window 18 to facilitate the user to observe the condition inside the discharge bin 3. Two support frames 16 are fixedly connected to the upper end face of the screw conveyor 2. Both support frames 16 are fixedly connected to the side wall of the discharge bin 3. The support frames 16 support the discharge bin 3 and improve the stability of the discharge bin 3. Two rotating rods are rotatably connected to the inner wall of the discharge bin 3. Multiple material distribution blades 4 are fixedly connected to the two rotating rods. Two scraping components are installed on the inner wall of the discharge bin 3.

[0022] The scraping assembly includes two annular guide grooves 5 on the inner wall of the feeding bin 3, multiple distributing blades 4 with sliding grooves 6 on both sides, and scrapers 7 slidably connected in the multiple sliding grooves 6. Each scraper 7 slides in the two annular guide grooves 5. A servo motor 8 is fixedly installed on the side wall of the feeding bin 3. A protective shell 17 is fixedly connected to the side wall of the feeding bin 3. The protective shell 17 matches the servo motor 8 and can protect the servo motor 8 from damage caused by external interference. The rotating end of the servo motor 8 is fixedly connected to one of the rotating rods. Two sprockets 9 are rotatably connected to the side wall of the feeding bin 3. The two sprockets 9 are driven by a chain 10. The two sprockets 9 are fixedly connected to the two rotating rods respectively. A feeding assembly is installed on the feeding bin 3. A funnel 15 is connected to the upper end face of the feeding bin 3.

[0023] The material feeding assembly includes a vertical plate fixedly connected to the upper end face of the feeding bin 3. Multiple springs 11 are fixedly connected to the side wall of the vertical plate. A connecting plate is fixedly connected between the multiple springs 11.

[0024] The detailed working process of this utility model is as follows:

[0025] The device is placed in the designated position, and then powder is added into the funnel 15. At the same time, the servo motor 8 starts working, causing the rotating rod to rotate and the distributing blade 4 to start rotating. Through double-rotation feeding, the problem of easy air leakage and blockage of powder materials during the feeding process is solved, making the feeding speed more uniform. During the feeding process, the scraper 7 slides along the annular guide groove 5 and moves along the sliding groove 6, so that the scraper 7 can slide on the distributing blade 4 to scrape off the powder on the surface of the distributing blade 4, avoiding the powder from adhering and accumulating on the surface of the distributing blade 4, thereby ensuring the conveying efficiency of the distributing blade 4. When the distributing blade 4 rotates, it will continuously contact the actuating plate 13. Under the limit of the spring 11, the connecting rod will slide on the feeding bin 3, causing the actuating rod 14 to reciprocate, which can prevent the powder from accumulating in the funnel 15, facilitate feeding, and ensure that the powder feeding speed is more uniform.
