Description

Technical Field

[0001] This utility model relates to the field of feeding hopper technology, and in particular to an activated carbon recovery feeding hopper with adjustable feed rate. Background Technology

[0002] Activated carbon is a specially treated carbon material with a highly developed pore structure and a huge specific surface area, giving it excellent adsorption performance. Activated carbon recovery feeding hopper is a special device used in the process of activated carbon recovery, regeneration or reuse, and is usually used for feeding activated carbon in industrial production.

[0003] In traditional technology, activated carbon material is typically poured directly into the feeding hopper and allowed to flow naturally under gravity. This method is prone to blockage at the feeding port, hindering material flow and making it difficult to adjust the feeding rate. Furthermore, as the activated carbon flows from the feeding hopper into the transfer pipe, its blocky and granular form easily adheres to the inner wall, causing adhesion. This adhered activated carbon is difficult to discharge, and the deep inner wall of the transfer pipe makes cleaning difficult, further contributing to blockages and reducing the flowability of the activated carbon. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable feed rate activated carbon recovery hopper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable feed rate activated carbon recovery feeding hopper, including a feeding hopper, a transmission pipe being connected through the lower surface of the feeding hopper, two ball valves being connected through the lower surface of the transmission pipe, a rotating ring being rotatably connected to one end of each ball valve, a feeding pipe being rotatably connected to the lower surface of the rotating ring, a bracket being fixedly connected to one side of each of the two feeding pipes, the two brackets being fixedly connected to the lower surface of the transmission pipe, a feeding shell being connected through the two feeding pipes, and a wall scraping assembly being provided inside the transmission pipe;

[0006] The scraping assembly includes two rotating rods, which are rotatably connected to the two ends inside the transmission tube.

[0007] As a further description of the above technical solution:

[0008] The two rotating rods are rotatably connected, and both ends of the transmission tube are fixedly equipped with variable speed motors.

[0009] As a further description of the above technical solution:

[0010] The rotating rod is fixedly connected to the output end of the variable speed motor. A spiral blade is fixedly connected to the outside of the rotating rod, and a first scraper is fixedly connected to one side of the spiral blade.

[0011] As a further description of the above technical solution:

[0012] A gear ring is fixedly connected to the outside of the rotating ring, a drive bevel gear is fixedly connected to one end of the rotating rod, and mounting sleeves are fixedly connected to both ends of the transmission tube. A connecting rod is rotatably connected inside the mounting sleeve.

[0013] As a further description of the above technical solution:

[0014] One end of the connecting rod is fixedly connected to a connecting gear, which is meshed with the gear ring. The other end of the connecting rod is fixedly connected to a driven bevel gear, which is meshed with the driving bevel gear. A second scraper is fixedly connected to the inner wall of the rotating ring.

[0015] As a further description of the above technical solution:

[0016] A heightening assembly is provided on one side of the transmission tube. The heightening assembly includes a fixing plate, which is fixedly connected to one side of the transmission tube. A stepper motor is fixedly installed on the lower surface of the fixing plate, and a lead screw is fixedly connected to the output end of the stepper motor.

[0017] As a further description of the above technical solution:

[0018] The lead screw is externally threaded with a connecting block, and a heightening frame is fixedly connected to one side of the connecting block. A frame cover is hinged to the upper surface of the heightening frame. A columnar groove is opened inside the heightening frame, and a long rod is slidably connected inside the columnar groove. The long rod is fixedly connected to the upper surface of the fixing plate. A sealing ring is provided on the outside of the feed hopper. The sealing ring is made of rubber, and the heightening frame is slidably connected to the outside of the sealing ring.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the wall scraping component, utilizes the different rotation speeds of the spiral blades on both sides of the activated carbon recovery feeding hopper to facilitate the conveying of activated carbon material at different speeds, thereby controlling the feeding amount. The ball valve's on / off function also facilitates the adjustment of the activated carbon feeding amount. Furthermore, the scraping of the inner wall of the transmission pipe by the first scraper and the scraping of the inner wall of the feeding pipe by the second scraper helps reduce the adhesion of activated carbon material inside the transmission pipe and the feeding pipe, which helps reduce the pipe blockage caused by material adhesion and thus improves the fluidity of the activated carbon material during conveying.

[0021] 2. By setting up a heightening component, the height of the feed hopper can be easily adjusted using a heightening frame. When the heightening frame is raised, more activated carbon material can be accommodated inside the feed hopper. When the heightening frame is retracted, less material can be added inside the feed hopper. This allows for easy adjustment of the height of the heightening frame according to the amount of activated carbon material to be conveyed, thus improving the flexibility of the present invention in use.

[0030] 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.

[0031] As attached Figure 1-6As shown, one embodiment of this utility model is provided: an adjustable feed rate activated carbon recovery feeding hopper, including a feeding hopper 1, a transmission pipe 2 is connected through the lower surface of the feeding hopper 1, two ball valves 3 are connected through the lower surface of the transmission pipe 2, a rotating ring 4 is rotatably connected to one end of the ball valve 3, a feeding pipe 5 is rotatably connected to the lower surface of the rotating ring 4, a bracket is fixedly connected to one side of the two feeding pipes 5, the two brackets are fixedly connected to the lower surface of the transmission pipe 2, a feeding shell 6 is connected through the two feeding pipes 5, a wall scraping assembly is provided inside the transmission pipe 2, the rotating ring 4 is used to install a toothed ring 11, and the feeding shell 6 is used for feeding activated carbon material;

[0032] The wall scraping assembly includes two rotating rods 7, which are rotatably connected to the two ends inside the transmission pipe 2. The rotating rods 7 are used to install the spiral blades 9 and drive them to rotate.

[0033] As attached Figure 3 As shown, the two rotating rods 7 are rotatably connected. Both ends of the transmission pipe 2 are fixedly installed with variable speed motors 8. The rotating rods 7 are fixedly connected to the output end of the variable speed motors 8. The outside of the rotating rods 7 is fixedly connected with spiral blades 9. A first scraper 10 is fixedly connected to one side of the spiral blades 9. A toothed ring 11 is fixedly connected to the outside of the rotating ring 4. When the rotation speeds of the spiral blades 9 on both sides are different, the feeding speed of the material will be different, which makes it easy to adjust the feed rate. The first scraper 10 is in contact with the inner wall of the transmission pipe 2, which makes it easy to scrape the inner wall.

[0034] As attached Figure 4 As shown, a driving bevel gear 12 is fixedly connected to one end of the rotating rod 7. Both ends of the transmission pipe 2 are fixedly connected to mounting sleeves 13. A connecting rod 14 is rotatably connected inside the mounting sleeve 13. The connecting rod 14 is rotatably connected inside the mounting sleeve 13. A connecting gear 16 is fixedly connected to one end of the connecting rod 14. The connecting gear 16 is meshed with the gear ring 11. A driven bevel gear 17 is fixedly connected to the other end of the connecting rod 14. The driven bevel gear 17 is meshed with the driving bevel gear 12. A second scraper 18 is fixedly connected to the inner wall of the rotating ring 4. The mounting sleeve 13 facilitates the installation of the connecting rod 14. The second scraper 18 can rotate with the rotation of the rotating ring 4, so that the second scraper 18 scrapes the inner wall of the feed pipe 5.

[0035] As attached Figure 1 As shown, a heightening assembly is provided on one side of the transmission pipe 2. The heightening assembly includes a fixing plate 19, which is fixedly connected to one side of the transmission pipe 2. A stepper motor 20 is fixedly installed on the lower surface of the fixing plate 19. A lead screw 21 is fixedly connected to the output end of the stepper motor 20. A connecting block 22 is threadedly connected to the external thread of the lead screw 21. A heightening frame 23 is fixedly connected to one side of the connecting block 22. A frame cover 24 is hinged to the upper surface of the heightening frame 23. With the connection of the lead screw 21, the connecting block 22 can easily drive the heightening frame 23 to move up and down.

[0036] As attached Figure 6 As shown, the interior of the heightened frame 23 has a columnar groove 25 that matches the length of the long rod 15.

[0037] As attached Figure 1 As shown, a long rod 15 is slidably connected inside the columnar groove 25. The long rod 15 is fixedly connected to the upper surface of the fixed plate 19. A sealing ring 26 is provided on the outside of the feed hopper 1. The sealing ring 26 is made of rubber. The lifting frame 23 is slidably connected to the outside of the sealing ring 26. The length of the long rod 15 matches that of the columnar groove 25 and is cylindrical. The sealing ring 26 improves the sealing performance of the connection between the lifting frame 23 and the feed hopper 1.

[0038] Working Principle: When conveying activated carbon material, the activated carbon material is first poured into the feed hopper 1. Then, the variable speed motors 8 on both sides are turned on. When the variable speed motors 8 drive the rotating rods 7 to rotate, the rotating rods 7 on both sides rotate in opposite directions, thereby driving the spiral blades 9 to rotate. Then, the speed of the variable speed motors 8 on both sides is adjusted according to the required feed rate. When the speed is slowed down, it is convenient to convey small amounts of material. When the speed is increased, it is suitable for conveying large amounts of material. At the same time, the ball valves 3 on both sides are opened according to the usage requirements. If a small amount of material needs to enter, only one ball valve 3 needs to be opened. If a large amount of material needs to flow, both ball valves 3 are opened to convey the material. When the rotating rod 7 rotates, it drives the active bevel gear 12 to rotate, which in turn drives the driven bevel gear 17 to rotate. The driven bevel gear 17 then drives the connecting rod 14 to rotate inside the mounting sleeve 13, which in turn drives the connecting gear 16 to rotate. Under the action of the connecting gear 16 meshing with the gear ring 11, the gear ring 11 rotates, which in turn drives the rotating ring 4 to rotate. This, in turn, drives the second scraper 18 to revolve, scraping the inner wall of the feed pipe 5. When the spiral blade 9 rotates, it drives the first scraper 10 to rotate, causing the first scraper 10 to scrape the inner wall of the transmission pipe 2, thereby scraping and cleaning the material adhering to the inner wall of the transmission pipe 2.

[0039] When a large amount of material needs to be added, the stepper motor 20 is turned on, and its output end drives the lead screw 21 to rotate. When the lead screw 21 rotates, the long rod 15 slides inside the columnar groove 25, which drives the connecting block 22 to move upward. This causes the connecting block 22 to drive the heightening frame 23 to slide upward outside the sealing ring 26, thereby making it easier to raise the feed hopper 1 and add more material.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
