Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a rotary feeder for chemical safety. Background Technology

[0002] Chemical production refers to the process of converting one or more raw materials into useful chemical products or substances using chemical principles and technologies. Chemical production typically includes processes such as raw material preparation, reaction processing, separation and purification, and product preparation. Among these processes, mixing, heating, and stirring the raw materials cause chemical changes; therefore, the raw material mixing stage requires the feeding of raw materials.

[0003] In existing technologies, traditional feeding methods mostly rely on manual operation, such as manual pouring, open-top feeding, or simple mechanical conveying, which have many limitations. Chemical raw materials often have flammable, explosive, toxic, or corrosive properties (such as organic solvents, strong acids, and dust). Open-top feeding can easily lead to material leakage, causing fires, explosions, or personnel poisoning accidents. For example, when dust reaches its explosive limit in air, it can be ignited by a static spark. Intermittent manual operation leads to discontinuous production, and frequent start-ups and shutdowns increase energy consumption and reduce production capacity. Therefore, we propose a rotary feeder for chemical safety to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary feeder for chemical safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A circular plate is rotatably connected to the top of the circular partition. Two material cylinders are fixedly interconnected at the top of the circular plate. A circular frame is fixedly connected to the bottom of the circular partition. A first servo motor is fixedly connected inside the circular frame. The top of the output shaft of the first servo motor is fixedly connected to the bottom of the circular plate. A rectangular feeding tube is fixedly interconnected at the bottom of the circular partition. Two arc-shaped rubber guide plates are fixedly connected inside the rectangular feeding tube. A rotating roller is rotatably connected inside the rectangular feeding tube. Multiple feeding grooves are evenly formed on the outer wall of the rotating roller. A drive assembly is provided on the outer wall of the rectangular feeding tube.

By setting the driving component, the rotating roller is driven to rotate, and the chemical raw materials are fed.

[0008] Preferably, the bottom of the feeding hopper is fixedly connected to a connecting pipe, and the outer wall of the feeding hopper is fixedly connected to two legs to support the feeding hopper.

[0009] Preferably, the top of the feeding hopper is hinged with a sealing cover to seal the top of the feeding hopper.

[0010] Preferably, the bottom of the circular partition has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the first servo motor. By setting the first servo motor to drive the circular partition to rotate, the two material cylinders will rotate.

[0011] Preferably, the tops of the two arc-shaped rubber guide plates are in contact with the bottom of the circular partition, and the two arc-shaped rubber guide plates assist the chemical raw materials to enter the arc-shaped groove.

[0012] Preferably, the outer wall of the rectangular feed tube has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the second servo motor.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution achieves uninterrupted automated feeding through alternating dual-cylinder feeding and quantitative feeding with rotating rollers, significantly improving production efficiency. Multiple arc-shaped grooves on the rotating rollers ensure quantitative conveying, guaranteeing feeding accuracy and process stability.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-5 As shown, a rotary feeder for chemical safety is disclosed, comprising a feeding bin 1, a connecting pipe 2 fixedly connected to the bottom of the feeding bin 1, an existing flange installed at the bottom of the connecting pipe 2, which can be connected to an existing reactor or screw conveyor, two legs 3 fixedly connected to the outer wall of the feeding bin 1, a sealing cover 4 hinged to the top of the feeding bin 1, the sealing cover 4 sealing the top of the feeding bin 1, a circular partition 5 fixedly connected inside the feeding bin 1, a circular plate 6 rotatably connected to the top of the circular partition 5, two material cylinders 7 fixedly connected to the top of the circular plate 6, the circular plate 6 supporting the two material cylinders 7, and multiple material cylinders 7 can be added to the circular plate 6 to meet the feeding of different raw materials.

[0024] A circular frame 8 is fixedly connected to the bottom of the circular partition 5. A first servo motor 9 is fixedly connected inside the circular frame 8. The circular frame 8 protects the first servo motor 9. A circular hole is opened at the bottom of the circular partition 5. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the first servo motor 9. The top of the output shaft of the first servo motor 9 is fixedly connected to the bottom of the circular plate 6.

[0025] A rectangular feed pipe 10 is fixedly connected to the bottom of the circular partition 5. Two arc-shaped rubber guide plates 11 are fixedly connected inside the rectangular feed pipe 10. The two arc-shaped rubber guide plates 11 assist the feed cylinder 7 to drop material downwards, and at the same time assist the chemical raw materials to rotate and be discharged downwards. The tops of the two arc-shaped rubber guide plates 11 are in contact with the bottom of the circular partition 5. A rotating roller 12 is rotatably connected inside the rectangular feed pipe 10. Multiple feed grooves 13 are evenly opened on the outer wall of the rotating roller 12. The rotation of the rotating roller 12 causes the multiple feed grooves 13 to rotate, realizing intermittent feeding.

[0026] The outer wall of the rectangular feed tube 10 is provided with a drive assembly, which includes a second servo motor 14. The outer wall of the rectangular feed tube 10 has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the second servo motor 14. Existing encoders are installed on the outer walls of the output shafts of the first servo motor 9 and the second servo motor 14. The encoders can accurately measure the position, angle or linear displacement of the object being measured and provide accurate position feedback signals, thereby achieving high-precision positioning control. A bracket is fixedly connected to the outer wall of the rectangular feed tube 10, and the top of the bracket is fixedly connected to the outer wall of the second servo motor 14. The outer wall of the output shaft of the second servo motor 14 is fixedly connected to the outer wall of the rotating roller 12.

[0027] Working principle: During use, two chemical raw materials are placed inside the two material cylinders 7. The sealing cover 4 is rotated to seal the top of the feeding bin 1. When feeding is required, the first servo motor 9 drives the circular plate 6 to rotate. The rotation of the circular plate 6 causes the two material cylinders 7 to rotate. When one of the material cylinders 7 is at the top of the rectangular feeding pipe 10, the material cylinder 7 and the rectangular feeding pipe 10 are interconnected. The chemical raw materials in the material cylinder 7 enter one of the feeding grooves 13 of the rotating roller 12 along the two arc-shaped rubber guide plates 11. The second servo motor 14 drives the rotating roller 12 to rotate. The rotation of the rotating roller 12 causes multiple feeding grooves 13 to rotate, so that the subsequent feeding grooves 13 continue to be filled with chemical raw materials. After the chemical raw materials face downward, they fall downward by their own weight and are discharged along the inner wall of the feeding bin 1 and the connecting pipe 2. The connecting pipe 2 can be connected to an existing reactor or to a screw conveyor for transportation.
