These machines and equipment play a vital role in chemical production, and are used to realize a series of chemical processes such as raw material pretreatment, chemical reactions, and the separation and purification of reaction products.
[0003] In chemical production, especially in the production of liquid materials, two liquids need to be mixed in a 1:1 ratio to obtain the target liquid. Existing equipment requires precise proportioning before the two liquids are mixed, and most of these proportions are done manually, which is slow and inefficient. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated quantitative feeding device for chemical machinery.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated quantitative feeding device for chemical machinery, comprising a mixing tank, wherein a float plate is provided inside the mixing tank, and a positioning rod is fixedly connected to the top of the float plate, and there are two positioning rods. The outer walls of the two positioning rods are provided with grooves, and the tops of the two positioning rods are fixedly connected with top plates. The bottom of the top plates is fixedly connected with wedge blocks. The top of the mixing tank is connected to a top cover by bolts, and the top of the top cover is fixedly connected with a feed pipe, and there are two feed pipes. The outer walls of the two feed pipes are fixedly connected with baffles, and there are two baffles in each case. The baffles are provided with limiting grooves inside, and a partition is provided between two adjacent baffles. One end of the partition is located inside the feed pipe, and the outer walls of both sides of the other end of the partition are fixedly connected with limiting posts. The limiting posts penetrate the interior of the limiting grooves. The top of the top cover is provided with through grooves, and there are two through grooves. The two positioning rods are respectively located inside the two through grooves. The inner walls of the two feed pipes (8) are fixedly connected with blocks (14).
[0006] As a further description of the above technical solution:
[0007] The tops of both positioning rods penetrate the top cover, and both top plates are located on top of the top cover.
[0008] As a further description of the above technical solution:
[0009] A motor is fixedly connected to the top of the top cover, and a rotating shaft is fixedly connected to the output end of the motor. The floating plate is sleeved on the outside of the rotating shaft, and a horizontal plate is fixedly connected to the outer wall of the rotating shaft. There are multiple horizontal plates, and a vertical plate is fixedly connected to the other end of each of the multiple horizontal plates.
[0010] As a further description of the above technical solution:
[0011] The bottom of the rotating shaft extends into the interior of the mixing tank, and the plurality of vertical plates are in contact with the inner wall of the mixing tank.
[0012] As a further description of the above technical solution:
[0013] A guide pipe is fixedly connected to the bottom of the mixing tank, and a solenoid valve is installed on the upper outer wall of the guide pipe. Support legs are fixedly connected to the bottom edge of the mixing tank, and there are multiple support legs. Each of the multiple support legs has a buffer pad at its bottom.
[0014] As a further description of the above technical solution:
[0015] The bottom of the inner wall of the groove is inclined, and the distance between two adjacent wedges is greater than the distance between two adjacent baffles.
[0016] This utility model has the following beneficial effects:
[0017] 1. Two liquids to be mixed enter the mixing tank through two separate feed pipes. At this time, one end of each of the two baffles extends out of the feed pipes. The float moves upward as liquid is added. As the float rises, the two positioning rods connected to its top, along with the top plate connected to the top of the positioning rods, move upward together. During the upward movement of the positioning rods, the inclined side of the bottom of the inner wall of the groove squeezes the baffle, pushing it into the feed pipe. The baffle, once inside the feed pipe, blocks the connection between the baffle and the mixing tank, preventing liquid from entering. The liquid in the mixing tank is then discharged after further mixing. During the discharge process, the float descends as the liquid in the mixing tank decreases. When the float descends close to the bottom of the inner wall of the mixing tank, a wedge-shaped block squeezes the limiting post, causing the limiting post and the baffle to move outward from the feed pipe. The feed pipe then reconnects with the mixing tank, allowing the liquid to re-enter the mixing tank. This achieves the function of quantitative feeding, which is fast, efficient, and improves production efficiency.
[0018] 2. After the two baffles block the connection between the two feed pipes and the mixing tank, the motor drives the rotating shaft to rotate, which in turn causes the multiple horizontal and vertical plates connected to the rotating shaft to rotate, stirring and mixing the liquid in the mixing tank. After the stirring and mixing is completed, the solenoid valve operates, allowing the mixed liquid to flow out through the guide pipe. When the float plate approaches the bottom of the inner wall of the mixing tank, the solenoid valve closes. After the float plate fully contacts the bottom of the inner wall of the mixing tank, the liquid continues to enter the mixing tank through the feed pipe. The above process is repeated when the device is running. Attached Figure Description

[0029] Reference Figure 1-7This utility model provides an automated quantitative feeding device for chemical machinery, comprising a mixing tank 1, wherein a float plate 2 is provided inside the mixing tank 1, and two positioning rods 3 are fixedly connected to the top of the float plate 2. The outer walls of both positioning rods 3 are provided with grooves 4, the bottom of the inner walls of the grooves 4 being inclined. A top plate 5 is fixedly connected to the top of both positioning rods 3, and a wedge block 6 is fixedly connected to the bottom of the top plate 5. A top cover 7 is bolted to the top of the mixing tank 1, and the tops of both positioning rods 3 penetrate the top cover 7. Both top plates 5 are located on top of the top cover 7, and two feed pipes 8 are fixedly connected to the top of the top cover 7. Two feed pipes 8 are fixedly connected to the outer walls of two baffles 9, and there are two baffles 9 in each case. The distance between two adjacent wedge blocks 6 is greater than the distance between two adjacent baffles 9. A limiting groove 10 is opened inside the baffle 9. A partition 11 is set between two adjacent baffles 9. One end of the partition 11 is located inside the feed pipe 8. The other end of the partition 11 is fixedly connected to the outer walls on both sides of the partition 11. The limiting post 12 penetrates the inside of the limiting groove 10. A through groove 13 is opened on the top of the top cover 7, and there are two through grooves 13. Two positioning rods 3 are located inside the two through grooves 13 respectively. A stop block 14 is fixedly connected to the inner walls of the two feed pipes 8.
[0030] Two liquids to be mixed enter the mixing tank 1 through two feed pipes 8. At this time, one end of each of the two baffles 11 extends out of the two feed pipes 8. The float 2 moves upward as the liquid is added. When the float 2 moves upward, the two positioning rods 3 connected to its top and the top plate 5 connected to the top of the positioning rods 3 move upward together. During the upward movement of the positioning rods 3, the inclined side of the bottom of the inner wall of the groove 4 squeezes the baffle 11, pushing the baffle 11 into the feed pipe 8. The baffle 11 enters the feed pipe 8 and blocks its connection with the mixing tank 1, preventing the liquid from entering the mixing tank 1. The liquid in the mixing tank 1 is discharged after subsequent stirring and mixing. During the discharge process, the float 2 descends as the liquid in the mixing tank 1 decreases. When the float 2 descends close to the bottom of the inner wall of the mixing tank 1, the wedge block 6 squeezes the limiting post 12, causing the limiting post 12 and the baffle 11 to move out of the feed pipe 8. The feed pipe 8 is connected to the mixing tank 1 again, and the liquid re-enters the mixing tank 1, realizing the function of quantitative addition of materials. It is fast and efficient.
[0031] A motor 15 is fixedly connected to the top of the top cover 7. A rotating shaft 16 is fixedly connected to the output end of the motor 15. A float 2 is sleeved on the outside of the rotating shaft 16. A horizontal plate 17 is fixedly connected to the outer wall of the rotating shaft 16. There are multiple horizontal plates 17. A vertical plate 18 is fixedly connected to the other end of each horizontal plate 17. The bottom of the rotating shaft 16 extends into the interior of the mixing tank 1. The multiple vertical plates 18 are in contact with the inner wall of the mixing tank 1. A guide pipe 19 is fixedly connected to the bottom of the mixing tank 1. A solenoid valve 20 is installed on the upper outer wall of the guide pipe 19. A support foot 21 is fixedly connected to the bottom edge of the mixing tank 1. There are multiple support feet 21. A buffer pad 22 is provided at the bottom of each support foot 21.
[0032] After the two baffles 11 block the connection between the two feed pipes 8 and the mixing tank 1, the motor 15 drives the rotating shaft 16 to rotate, which in turn causes the multiple horizontal plates 17 and vertical plates 18 connected to the rotating shaft 16 to rotate, stirring and mixing the liquid in the mixing tank 1. After the stirring and mixing is completed, the solenoid valve 20 is activated, allowing the mixed liquid to flow out through the guide pipe 19. When the float plate 2 approaches the bottom of the inner wall of the mixing tank 1, the solenoid valve 20 closes. After the float plate 2 fully contacts the bottom of the inner wall of the mixing tank 1, the liquid continues to enter the mixing tank 1 through the feed pipe 8. The above process is repeated when the device is running.
[0033] Working principle: Two liquids to be mixed enter the mixing tank 1 through two feed pipes 8, respectively. At this time, one end of each of the two baffles 11 extends out of the two feed pipes 8. The float 2 moves upward as the liquid is added. When the float 2 moves upward, the two positioning rods 3 connected to its top and the top plate 5 connected to the top of the positioning rods 3 also move upward. During the upward movement of the positioning rods 3, the inclined side of the bottom of the inner wall of the groove 4 squeezes the baffle 11, pushing the baffle 11 into the feed pipe 8. The baffle 11 entering the feed pipe 8 blocks its connection with the mixing tank 1, preventing the liquid from entering the mixing tank. Tank 1 is then started. Subsequently, motor 15 drives shaft 16 to rotate, which in turn causes multiple horizontal plates 17 and vertical plates 18 connected to shaft 16 to rotate, stirring and mixing the liquid in mixing tank 1. After stirring and mixing is completed, solenoid valve 20 is activated, allowing the mixed liquid to flow out through guide pipe 19. During this process, the liquid in mixing tank 1 decreases slowly, and float 2 descends accordingly. When float 2 approaches the bottom of the inner wall of mixing tank 1, solenoid valve 20 closes. After float 2 fully contacts the bottom of the inner wall of mixing tank 1, the liquid continues to enter mixing tank 1 through feed pipe 8. The above process is repeated during device operation.
