Description

Technical Field

[0001] This utility model relates to the field of drug delivery technology, and in particular to a drug delivery device for accurately dispensing liquid drugs. Background Technology

[0002] During operation, aeration tanks often require the addition of chemicals to improve their efficiency. However, directly pouring chemicals into the aeration tank makes it impossible to accurately control the dosage, resulting in either too much or too little chemicals being added, which affects the efficiency of the aeration tank. Furthermore, wastewater treatment plants have a large demand for chemicals, and existing technologies mostly use stirred tanks to prepare the chemical solutions. However, using large stirred tanks results in high production costs, while using small stirred tanks cannot meet the needs of wastewater treatment plants.

[0003] A search revealed that utility model CN217627778U discloses a chemical dosing device for an aeration tank. However, this device has the following drawbacks during use:

[0004] The use of gas to deliver the medicine during the process makes it difficult to control the dosage, which can easily lead to too much or too little medicine.

[0005] It is inconvenient to administer multiple agents simultaneously during use, making it difficult to use.

[0006] Therefore, those skilled in the art provide a dosing device for accurately adding liquid drugs to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precise liquid drug dosing device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A dosing device for precisely adding liquid agents includes an aeration tank, a connecting tank, and multiple adjusting mechanisms. Two connecting plates are snapped onto the top of the aeration tank, and the connecting plates are fixedly connected to the aeration tank by locking components. The connecting tank is fixedly disposed between the two connecting plates, and a partition is fixedly provided on the inner wall of the connecting tank. Multiple retaining rings are fixedly provided on the top of the partition, and multiple storage tanks for storing agents are formed between the multiple retaining rings and the connecting tank.

[0010] The bottom of the partition is provided with a first row of medicine holes corresponding to the medicine storage tank. The top of the partition is provided with a rotating plate. The top of the rotating plate is fixedly provided with a metering tank that works in conjunction with the first row of medicine holes. When the metering tank is aligned with the first row of medicine holes, the medicine in the medicine storage tank flows into the metering tank. The bottom of the connecting bucket is provided with a second row of medicine holes that works in conjunction with the metering tank. When the metering tank is aligned with the second row of medicine holes, the medicine in the metering tank is discharged.

[0011] A motor is fixedly installed on the top of the partition, and the output end of the motor is fixedly connected to the rotating plate to provide power to the rotating plate.

[0012] The regulating mechanism is installed inside the metering tank and is used to adjust the volume of the metering tank.

[0013] As a further embodiment of this utility model, the fixing member includes a bolt with a through thread on one end of the connecting plate, one end of which abuts against the outside of the aeration tank, for fixing the connecting plate to the aeration tank.

[0014] As a further improvement of this invention, the height of the multiple retaining rings increases sequentially from the outside to the inside, serving to isolate multiple drug storage tanks.

[0015] As a further embodiment of this utility model, the top of the partition is provided with a rotating shaft that rotatably extends through it, the bottom of the rotating shaft is rotatably connected to the bottom wall of the connecting barrel, the rotating plate is fixedly sleeved on the rotating shaft, and the output end of the motor is fixedly connected to the rotating shaft.

[0016] As a further embodiment of this utility model, the motor is located inside the middle retaining ring, and the top of the middle retaining ring is sealed to protect the motor.

[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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0031] Reference Figures 1-5 A precise liquid dosing device includes an aeration tank 1, a connecting tank 4, and multiple adjusting mechanisms. The top of the aeration tank 1 has two connecting plates 2, which are fixedly connected to the aeration tank 1 by locking components. Specifically, the locking component is a bolt 3, which is threaded through one end of the connecting plate 2, and one end of the bolt 3 abuts against the outside of the aeration tank 1, thus firmly fixing the connecting plate 2 to the aeration tank 1.

[0032] The connecting barrel 4 is fixedly installed between two connecting plates 2, and a partition 5 is fixed to the inner wall of the connecting barrel 4. The top of the partition 5 is designed with multiple retaining rings 6, which form multiple medicine storage tanks 7. The height of these retaining rings 6 increases from the outside to the inside, and are used to isolate the multiple medicine storage tanks 7.

[0033] At the bottom of the partition 5, a first row of medicine holes 11 corresponding to the medicine storage tank 7 is provided. Simultaneously, a rotating plate 12 is rotatably mounted on the top of the partition 5. The rotation of the rotating plate 12 is achieved via a rotating shaft 10, the bottom of which is rotatably connected to the bottom wall of the connecting tank 4, while the rotating plate 12 is fixedly sleeved on the rotating shaft 10. A metering container 13, which mates with the first row of medicine holes 11, is fixedly fixed through the top of the rotating plate 12. When the metering container 13 aligns with the first row of medicine holes 11, the medicine in the medicine storage tank 7 flows into the metering container 13.

[0034] To drive the rotating plate 12 to rotate, a motor 15 is fixedly installed on the top of the partition 5. The output end of the motor 15 is fixedly connected to the rotating shaft 10, thereby providing power to the rotating plate 12. It is worth noting that the motor 15 is located inside the middle retaining ring 6, and the top of the middle retaining ring 6 is sealed to protect the motor 15.

[0035] The bottom of the connecting tank 4 is provided with a second row of medicine holes 14 that cooperate with the metering tank 13. When the metering tank 13 is aligned with the second row of medicine holes 14, the medicine in the metering tank 13 will be discharged. In order to ensure that the metering tank 13 does not leak during rotation, the positions of the first row of medicine holes 11 and the second row of medicine holes 14 are designed to be staggered, so that both ends of the metering tank 13 can be sealed.

[0036] To adjust the volume of the metering containers 13, each container 13 is equipped with an adjustment mechanism. The adjustment mechanism includes an adjustment cylinder 19 slidably disposed within the container 13. Multiple first support rods 16 are fixed to the inner wall of the top of the container 13, and a common fixing ring 17 is fixed to the adjacent sides of these first support rods 16. A screw 18 is rotatably mounted through the top of the fixing ring 17. A nut ring 21 is threaded onto the outer wall of the screw 18, and multiple second support rods 20 are fixed to the outer wall of the nut ring 21. The outer ends of these second support rods 20 are all fixedly connected to the inner wall of the adjustment cylinder 19. By rotating the screw 18, the position of the nut ring 21 can be adjusted, thereby adjusting the position of the adjustment cylinder 19, thus achieving the adjustment of the volume of the metering container 13.

[0037] In addition, to accelerate the discharge of the reagent in the metering tank 13, multiple fixed pipes 8 are installed through the top of the baffle 5. The tops of these fixed pipes 8 are connected to the same connecting pipe 9, and the other end of the connecting pipe 9 is connected to the aeration pipe. The bottom end of the fixed pipe 8 corresponds to the second row of reagent holes 14. When the metering tank 13 is aligned with the second row of reagent holes 14, the reagent can not only be discharged through the second row of reagent holes 14, but also enter the fixed pipes 8 and the connecting pipe 9 through the gas in the aeration pipe, and finally be sprayed into the metering tank 13, thus accelerating the discharge of the reagent.

[0038] Working principle: During installation, the two connecting plates 2 are clamped on the edge of the aeration tank 1, and the bolts 3 are tightened so that the top end of the bolts 3 abuts against the outside of the aeration tank 1 to fix the connecting plates 2. Then, one end of the connecting pipe 9 is connected to the aeration pipe.

[0039] When in use, different medicines are poured into the corresponding medicine storage tank 7, and then the motor 15 is started to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 can drive the rotating plate 12 to rotate. When the metering tank 13 corresponds to the first row of medicine holes 11, the medicine in the medicine storage tank 7 flows back into the corresponding metering tank 13. At the same time, the bottom of the metering tank 13 and the bottom of the connecting bucket 4 cooperate to form a sealed space.

[0040] As the rotation continues, the metering tank 13 is misaligned with the first row of medicine holes 11 during the rotation process. The first row of medicine holes 11 can be sealed by the rotating plate 12. When the metering tank 13 corresponds to the second row of medicine holes 14, the medicine in the metering tank 13 will be discharged into the aeration tank 1 through the second row of medicine holes 14. At the same time, the gas in the aeration pipe will enter the fixed pipe 8 through the connecting pipe 9, and then be blown towards the metering tank 13 through the fixed pipe 8 to accelerate the discharge of the medicine in the metering tank 13.

[0041] When it is necessary to adjust the volume of the metering tank 13, start the motor 15 to drive the rotating plate 12 to rotate, so that the metering tank 13 corresponds to the second dispensing hole 14. Then, turn the screw 18 with a wrench. Since the adjusting cylinder 19 slides inside the metering tank 13, and the nut ring 21 is fixed inside the adjusting cylinder 19 by the second support rod 20, the rotation of the screw 18 can drive the nut ring 21 to move upward. The upward movement of the nut ring 21 can drive the adjusting cylinder 19 to move upward. The upward movement of the adjusting cylinder 19 can change the volume of the metering tank 13, so that the drug can be accurately dispensed according to different drug ratios.

[0042] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
