[0002] CN202222848166.1 discloses a dosing device for river sewage treatment, including a tank, a box, a float, and an assembly cover. A stud is fixed to the upper end of the tank, and the stud is threaded onto the lower end of the float. Hanging rings are fixed to both sides of the float, and a traction rope is snapped onto the hanging rings. Sleeves are fixed to both sides of the inside of the float. The assembly cover is snapped and fixed to the upper opening of the float. Inserts are fixed to both sides of the lower end face of the assembly cover, and the inserts are inserted into the corresponding sleeves. A storage battery is fixed to the top of the inside of the tank. A liquid meter is provided at the bottom of the inside of the tank. The lower end of the tank is fixed to the box. A suction pump is fixed to the bottom of the inside of the box. A pipe is fixed to the upper end of the inside of the box.

[0003] The aforementioned prior art utilizes the buoyancy of a float to make the device float, and adjusts the device's position by pulling on tow ropes on both sides. After the tow ropes are fixed to the riverbank, a suction pump draws river water into the tank during the river's flow. The liquid metering device is then activated to introduce the drug solution from the tank into the tank through a drip pipe. At this point, the river water and drug solution in the tank mix and enter the pipe from the mixing tank. However, this dosing method can only be used on the water surface, and the mixing of the drug and water relies on the water flow. This dosing method tends to result in a higher concentration of drug closer to the water surface, which is not conducive to the mixing of water and drug. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example:

[0025] Please see Figures 1 to 5 This utility model provides a technical solution:

[0026] A dosing device for wastewater treatment includes a mounting frame 1, a storage tank 2, a connecting assembly 3, a buoyancy adjustment assembly 4, and a centrifugal dosing assembly 5, wherein:

[0027] The storage box 2 is movably installed in the mounting frame 1. The storage box 2 is vertically movable in the mounting frame 1. The connecting component 3 is located on the mounting frame 1. The centrifugal dosing component 5 is located on the lower side of the mounting frame 1. The storage box 2 is connected to the centrifugal dosing component 5 through the connecting component 3.

[0028] The buoyancy adjustment assembly 4 includes an elastic telescopic component 41, a connecting rod 42, and a float 43. The elastic telescopic component 41 is vertically and movably installed within the mounting frame 1, forming a vertically movable joint within the mounting frame 1. The actuating end of the elastic telescopic component 41 is connected to the storage tank 2. One end of the connecting rod 42 is hinged to the float 43, and the other end is hinged to the actuating end of the elastic telescopic component 41. The float 43 is horizontally and movably installed on the side of the storage tank 2. The buoyancy of the mounting frame 1 is controlled by changing the contact area between the float 43 and the water.

[0029] In a preferred embodiment, the connecting component 3 includes a fixed pipe 31 and a movable pipe 32. The fixed pipe 31 passes through the mounting frame 1 and is fixedly connected to it. The movable pipe 32 is movably installed inside the fixed pipe 31 and communicates with the storage bin 2. One end of the movable pipe 32 is fixedly mounted on the storage bin 2, and the other end is vertically movable within the movable pipe 32.

[0030] In a preferred embodiment, the elastic telescopic component 41 includes a movable sleeve 411 and a spring 412. The movable sleeve 411 is movably fitted onto the fixed tube 31, forming a vertical sliding joint on the fixed tube 31. The spring 412 is vertically positioned, with one end attached to the mounting bracket 1 and the other end connected to the movable sleeve 411. When the storage bin 2 is filled with material, the movable sleeve 411 moves downward and compresses the spring 412 under the weight of the storage bin 2 and the material. The greater the weight of the storage bin 2 and the material, the greater the compression.

[0031] In a preferred embodiment, the centrifugal dosing assembly 5 includes a rotating disk 51, a discharge pipe 52, a return spring 53, and a one-way valve 54. The rotating disk 51 is rotatably mounted on the fixed pipe 31 and the two are connected. The motor drives the rotating disk 51 to rotate, thereby generating centrifugal force. The discharge pipe 52 is located inside the mounting hole on the side of the rotating disk 51 through the return spring 53. The discharge pipe 52 is a horizontally moving pair in the mounting hole on the side of the rotating disk 51, and the discharge pipe 52 is connected to the mounting hole on the side of the rotating disk 51. One end of the discharge pipe 52 near the center of the rotating disk 51 is the feed end, and the other end is sealed. The discharge port is on the side of the discharge pipe 52. When the discharge pipe 52 is located in the mounting hole on the side of the rotating disk 51, the inner wall of the mounting hole on the side of the rotating disk 51 will abut against the discharge port, so that the discharge pipe 52 will not discharge at this time. When the discharge port of the discharge pipe 52 leaves the mounting hole on the side of the rotating disk 51 under the centrifugal force generated by the rotation of the rotating disk 51, the material will enter the connecting component 3 from the storage box 2 under the action of gravity, and then reach the mounting hole on the side of the rotating disk 51. Under the centrifugal force generated by the rotation of the rotating disk 51, the material will be discharged from the discharge port. A one-way valve 54 for discharging is provided on the side of the discharge end of the discharge pipe 52.

[0032] In a preferred embodiment, the storage tank 2 is mounted on the movable sleeve 411, and the connecting rod 42 is hinged to the side of the movable sleeve 411. When the movable sleeve 411 moves vertically on the fixed tube 31, it changes the area of ​​the float 43 extending out of the mounting frame 1 through the connecting rod 42, thereby changing the magnitude of the buoyancy.

[0033] In a preferred embodiment, the connecting component 3 further includes an L-shaped tube 33, and the fixing tube 31 is connected to the side mounting hole of the rotating disk 51 through the L-shaped tube 33.

[0034] The working principle of this utility model:

[0035] When using this device, first fill the storage tank 2 with material. At this time, under the gravity of the storage tank 2 and the material, the movable sleeve 411 moves downward and compresses the spring 412. At this time, the movable sleeve 411 will push the float 43 out of the mounting frame 1 through the connecting rod 42. Then, place the device into the water pool where the medicine needs to be added. At this time, the weight of the device is greater than the buoyancy of the device, and the device sinks to the bottom. Then, start the motor to drive the rotating disk 51 to rotate. At this time, the discharge pipe 52 will extend outward under the centrifugal force generated by the rotation of the rotating disk 51, so that the discharge hole of the discharge pipe 52 leaves the mounting hole on the side of the rotating disk 51. Under the gravity of the material, the material will enter the connecting component 3 from the storage tank 2, and then reach the mounting hole on the side of the rotating disk 51. Under the centrifugal force generated by the rotation of the rotating disk 51, the material will be discharged from the discharge hole.

[0036] As material is continuously discharged, the weight of the device decreases, making the device's gravity less than the buoyancy it experiences. As a result, the device floats up. As the material in the storage tank 2 decreases, the movable sleeve 411 moves upward under the elastic force of the spring 412. This, in turn, pulls the float plate 43 back to the mounting frame 1 via the connecting rod 42, further reducing the buoyancy of the device. Consequently, the device does not rise faster as its weight decreases, thus ensuring the efficiency of drug dosing.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
