Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, specifically a wastewater treatment dosing device. Background Technology
[0002] Wastewater refers to water that has been used and polluted during human life, industrial production, and other activities. Wastewater treatment utilizes physical, chemical, and biological methods to treat wastewater to meet certain water quality standards for reuse or discharge. The purpose is to remove or reduce various pollutants in dissolved, colloidal, and suspended states in wastewater to prevent harm to the ecological environment and human health. The addition of chemicals is indispensable in the wastewater treatment process. By adding different chemicals, impurities in the wastewater can be accelerated to settle or be purified.
[0003] The current method of adding chemicals to wastewater is generally by manual sprinkling. However, manual sprinkling makes it difficult to control the placement of the chemicals, which can easily lead to overly concentrated application. Furthermore, when chemicals accumulate, they are less likely to mix with the wastewater, reducing the reaction rate between the chemicals and the wastewater. Therefore, a wastewater treatment dosing device is proposed to solve the above problems. Utility Model Content

This solves the problem that existing methods of adding agents to wastewater are generally done manually by throwing the agent, which makes it difficult to control the placement of the agent, easily leading to overly concentrated agent dosing. Furthermore, when the agent is piled up, it is difficult to mix with the wastewater, thus reducing the reaction rate between the agent and the wastewater.

[0027] 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.
[0028] In the embodiments, by Figure 1-5 This invention discloses a wastewater treatment dosing device, comprising a base 1, a first support frame 2 fixedly connected to the top of the base 1, a lifting device 3 disposed inside the first support frame 2, a connecting frame 4 fixedly connected to the outside of the lifting device 3, a second motor 5 fixedly connected to the outside of the connecting frame 4, a fixed shaft 6 rotatably connected to the output shaft of the second motor 5 fixedly connected to the outside of the output shaft of the second motor 5, a fixed frame 7 slidably connected to the bottom of the fixed shaft 6, a plurality of drug storage cylinders 8 slidably connected inside the fixed frame 7, each of the plurality of drug storage cylinders 8 having a drug outlet hole inside, each of the plurality of drug storage cylinders 8 being fixedly connected to a connecting plate 9 on the outside of the plurality of drug storage cylinders 8, an electric push rod 10 slidably connected to the outside of the connecting frame 4 and the connecting plate 9, a second support frame 11 fixedly connected to the top of the base 1, a mixing tank 12 fixedly connected to the outside of the second support frame 11, a stirring device 13 disposed inside the mixing tank 12, and a discharge pipe 14 fixedly connected to the bottom of the mixing tank 12.
[0029] The lifting device 3 includes a first motor 31 fixedly connected to the outside of the first support frame 2. The output shaft of the first motor 31 is fixedly connected to a threaded rod 32 rotatably connected to the inside of the first support frame 2. The outside of the threaded rod 32 is connected to a transmission block 33 fixedly connected to the connecting frame 4 via a threaded transmission. The inside of the first support frame 2 is fixedly connected to a limiting rod 34 slidably connected to the transmission block 33.
[0030] In this embodiment, during actual use, the start of the first motor 31 will drive the threaded rod 32 to rotate, and under the action of the thread, the transmission block 33 will move in the direction of the thread. The limiting rod 34 is set parallel to the threaded rod 32, which stabilizes the direction of movement of the connecting frame 4.
[0031] The stirring device 13 includes a third motor 131 fixedly connected to the top of the stirring tank 12. The output shaft of the third motor 131 is fixedly connected to a stirring shaft 132 rotatably connected to the stirring tank 12. A plurality of stirring rods 133 are fixedly connected to the outside of the stirring shaft 132.
[0032] In this embodiment, during actual use, the start of the third motor 131 will drive the stirring shaft 132 to rotate, and cause the multiple stirring rods 133 on the outside of the stirring shaft 132 to rotate, so as to stir the mixture of the medicine and the liquid, making it convenient to sprinkle it and mix it with wastewater, thereby accelerating the reaction rate between the medicine and the wastewater.
[0033] The discharge pipe 14 is located above the single medicine storage cylinder 8. An electric valve is installed on the outside of the discharge pipe 14, and multiple medicine outlets are far away from the center of the connecting plate 9.
[0034] In this embodiment, during actual use, the electric valve can control the discharge of the liquid medicine. The liquid medicine can be discharged into the storage cylinder 8 through the discharge pipe 14. The discharge hole provides the position for the liquid medicine to be discharged from the storage cylinder 8. The position is relatively dispersed, which makes it more convenient for the liquid medicine to mix with the wastewater.
[0035] The fixed frame 7 has a first groove inside, and the connecting frame 4 has a first slider 15 that is slidably connected to the first groove on the outside.
[0036] In this embodiment, during actual use, as the second motor 5 drives the fixed frame 7 to rotate via the fixed shaft 6, the first slider 15 slides within the first groove to provide support for the fixed frame 7 and stabilize its rotation direction, preventing it from shifting and falling.
[0037] The connecting plate 9 has a second sliding groove inside, and the bottom of the electric push rod 10 is fixedly connected to a second slider 16 that is slidably connected to the second sliding groove.
[0038] In this embodiment, during actual use, the connecting plate 9 will also rotate during the rotation of the fixed frame 7. Since the electric push rod 10 is in a fixed state, the second slider 16 below it will slide relative to the connecting plate 9. Under the action of the electric push rod 10, the connecting plate 9 can also move up and down to expose the medicine outlet of the medicine storage cylinder 8.
[0039] Working principle:
[0040] When adding chemicals to wastewater, the chemicals are first placed in the mixing tank 12. The third motor 131 is then started to mix the chemicals with water or other chemicals. The mixed solution is then discharged from the discharge pipe 14 through the electric valve and flows into the storage tank 8 below. At the same time, the second motor 5 starts, causing the fixed frame 7 to rotate the storage tank 8, thus filling the multiple storage tanks 8 with chemicals. The electric valves and motors are connected to the programmable logic controller (PLC) distributed control system and other control equipment in the control room via a fieldbus, sending open / close or... The opening is adjusted to maintain stable or accurate drug delivery. After delivery, the first motor 31 can be started to lower the connecting frame 4 and submerge the lower end of the fixed frame 7 into the wastewater. When the drug outlet is inside the fixed frame 7, a rubber pad is installed inside the fixed frame 7 to prevent the drug from flowing out. At this time, the lower half of the drug storage cylinder 8 is also in the wastewater. Activating the electric push rod 10 can move the drug outlet of the drug storage cylinder 8 connected to the connecting plate 9 out of the fixed frame 7 and make it extend into the wastewater. The drug then diffuses in the wastewater. The drug diffuses to the surrounding area through multiple drug outlets, further accelerating the dissolution rate of the drug or its reaction with the wastewater.
