Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an automated quantitative dosing device for water treatment. Background Technology

[0002] In wastewater treatment processes, solid or powdered agents such as flocculants and disinfectants are added to the wastewater to achieve purification. Because solid and powdered agents are prone to clumping and bridging, uneven feeding can occur, making it difficult to accurately control the dosage per application. Furthermore, the dosage is easily affected by the material accumulation in the storage tank; excessive dosage leads to waste and secondary pollution, while insufficient dosage fails to meet discharge standards. These problems severely restrict the efficiency and quality of wastewater treatment. Therefore, this application proposes an automated quantitative dosing device for water treatment to solve these problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: an automated quantitative dosing device for water treatment, including a storage tank 1. The bottom of the storage tank 1 is concave, and a dosing tank 2 is fixedly connected to the bottom of the concave portion. A conical box 3 is fixedly installed inside the dosing tank 2. A shaft 4 is mounted on the conical box 3 via bearings. Multiple vertically distributed rotating plates 5 are fixedly connected to the top of the shaft 4 via a linkage rod. The rotating plates 5 are evenly distributed around the shaft 4, and the height of the rotating plates 5 is higher than that of the dosing tank 2. The rotating plates 5 are in contact with the dosing tank. The inner wall of the storage box 2 is equipped with a shaft 4 driven by a motor 6. The motor 6 is a low-speed motor and is fixedly installed on the outer wall of the storage box 1. The output shaft of the motor 6 is fixedly connected to the shaft 4 via a coupling. Several sets of dosing holes 7 are opened on the side wall of the dosing box 2. Multiple vertically distributed rotating plates 5 correspond one-to-one with the sets of dosing holes 7. The motor 6 is equipped with a control switch. The motor 6, which is fixedly installed on the outer wall of the storage box 1, is started by the control switch. The output shaft of the motor 6 drives the conical box 3 assembled on it via a coupling. The shaft 4 rotates and pauses continuously. Multiple rotating plates 5, connected to the top of the shaft 4 via a linkage rod, rotate and pause along with the shaft 4. During low-speed rotation, the rotating plates 5 agitate the pesticide inside the dosing tank 2, breaking up any clumps or bridging. This agitation is intermittently initiated during pesticide dispensing. When the rotating plates 5 pause rotation and are misaligned with the dosing holes 7 on the side wall of the dosing tank 2, the pesticide is discharged through multiple rows of dosing holes 7. The agent falls onto the inclined guide plate 8 at the bottom of the outer wall of the dosing tank 2. The agent flows along the guide plate 8 to the lower side away from the dosing tank 2 and finally falls into the sewage treatment tank to complete a single agent dosing action. When the rotating plate 5 stops rotating and the rotating plate 5 corresponds to the dosing hole 7 on the side wall of the dosing tank 2, the dosing hole 7 is blocked. This effectively breaks up the clumping and bridging of solid and powdered agents, ensuring smooth material feeding. It also allows for quantitative control of the agent dosage by combining the one-to-one correspondence between the dosing hole 7 and the guide plate 5.

[0021] Multiple guide plates 8 are installed at the bottom of the outer wall of the dosing tank 2. Dosing holes 7 are arranged in multiple rows along the vertical direction of the side wall of the dosing tank 2, and there is a one-to-one correspondence between the multiple sets of dosing holes 7 and the multiple guide plates 8. The guide plates 8 are set at an angle, and the side of the guide plate 8 away from the dosing tank 2 is the lower side. The agent is discharged through the multiple rows of dosing holes 7. The agent discharged from the dosing holes 7 falls onto the corresponding inclined guide plate 8 at the bottom of the outer wall of the dosing tank 2. The agent flows along the guide plate 8 to the lower side away from the dosing tank 2 and finally falls into the sewage treatment tank to complete the single agent dosing action. Small holes are opened on the guide plate, which can be used to release some agents through the small holes during the sliding process on the guide plate 8, thereby improving the dispersion of the agent.

[0022] The storage tank 1 is equipped with a dosing pipe 9, a sealing cap, and a mounting frame at its top. The mounting frame is used to install the storage tank 1 on the upper side of the water treatment tank and is connected to the frame on the upper side of the water treatment tank. The dosing pipe 9 is connected to the interior of the storage tank 1 and is inclined. The side of the dosing pipe 9 away from the storage tank 1 is the lower side. Open the sealing cap at the top of the dosing pipe 9 and pour the solid or powdered agent to be added into the storage tank 1 through the inclined dosing pipe 9. Under the action of gravity, the agent flows naturally into the dosing tank 2 below through the constricted part at the bottom of the storage tank 1. The inclination angle of the dosing pipe 9 is thirty degrees.

[0023] The operational steps for this application are as follows:

[0024] Open the sealing cap at the top of the dosing tube 9, and pour the solid or powdered agent to be added into the storage tank 1 through the inclined dosing tube 9. Under the action of gravity, the agent flows naturally into the dosing tank 2 below through the constricted part at the bottom of the storage tank 1.

[0025] The motor 6, which is fixedly installed on the outer wall of the storage box 1, is started. The output shaft of the motor 6 drives the shaft 4 mounted on the conical box 3 to rotate at low speed through the coupling. Multiple rotating plates 5, which are connected to the top of the shaft 4 through the linkage rod, rotate at low speed with the shaft 4.

[0026] During the low-speed rotation of the rotating plate 5, it agitates the agent inside the dosing tank 2 by adhering to the inner wall, breaking up any agglomeration or bridging of the agent. During this process, when the rotating plate 5 is misaligned with the dosing holes 7 on the side wall of the dosing tank 2, the agent is discharged through multiple rows of dosing holes 7. The agent discharged from the dosing holes 7 falls onto the inclined guide plate 8 corresponding to the bottom of the outer wall of the dosing tank 2. The agent flows along the guide plate 8 to the lower side away from the dosing tank 2 and finally falls into the sewage treatment tank to complete a single agent dosing action. When the rotating plate 5 stops rotating and the rotating plate 5 is aligned with the dosing holes 7 on the side wall of the dosing tank 2, the dosing holes 7 are sealed.

[0027] If the dosage of the pesticide needs to be adjusted, the time that the rotating plate 5 is offset from the dosing hole 7 can be controlled by adjusting the motor 6. The longer the rotating plate 5 is paused and the longer it is offset from the dosing hole 7, the greater the dosage of the pesticide will be, and vice versa.
