[0033] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0034] Example 1:

[0035] like Figures 1 to 4 As shown, this utility model provides a lime dosing device for sewage treatment, specifically including:

[0036] The material rack 1 has a connecting end 11 and a supporting end;

[0037] Material box 2 is connected to the connecting end 11; material box 2 has a bucket-shaped structure; it can be equipped with an opening and closing cover to close the material box 2, and the opening and closing cover can be equipped with an opening and closing material port;

[0038] The stirring shaft 3 is rotatably mounted inside the material box 2 via bearings;

[0039] The conveying pipe 4 has a channel opening 41 that communicates with the bottom of the material box 2, and one end of the conveying pipe 4 is provided with at least one discharge port 42;

[0040] The material conveying component 5 is rotatably disposed inside the material conveying pipe 4;

[0041] The transmission assembly 6 is connected to the stirring shaft 3 and the material conveying component 5 so that the stirring shaft 3 and the material conveying component 5 rotate synchronously;

[0042] The drive component 7 is fixedly installed at one end of the material rack 1 and is connected to the material conveying component 5 or the stirring shaft 3 for transmission.

[0043] See Figure 1 The stirring shaft 3 is provided with several stirring rods 31 or stirring blades. When it is a stirring rod 31, the stirring rod 31 is a straight rod structure and the stirring rods 31 are evenly distributed on the stirring shaft 3 along the circumferential and axial directions.

[0044] When it is a stirring plate, the stirring plate has an L-shaped structure and the stirring plates are evenly distributed on the stirring shaft 3 along the circumferential and axial directions.

[0045] See Figure 1 The drive component 7 is a drive motor connected to a reducer. The drive motor transmits power to the material conveying component 5 or the stirring shaft 3 through the reducer.

[0046] The conveying component 5 is a rotating shaft equipped with spiral conveying blades, which conveys lime located at the bottom of the material box 2, entering the conveying pipe 4 through the channel port 41, to the discharge port 42 via a spiral conveying method. The output end of the reducer is coaxially connected to the conveying component 5 via a coupling. Alternatively, the output shaft of the reducer can be detachably inserted into the conveying component 5 via a bushing, with the bushing fixed to the end of the conveying component 5.

[0047] The working principle of this utility model is as follows: When in use, the drive motor drives the reducer to rotate the conveying component 5. The transmission component 6 rotates synchronously with the stirring shaft 3 of the conveying component 5 to stir the lime raw material in the material box 2. The conveying component 5 located at the bottom of the material box 2 rotates to spirally push the lime from the discharge port 42 into the sewage tank.

[0048] Example 2:

[0049] As another embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the transmission assembly 6 includes a first transmission sprocket, a second transmission sprocket, and a transmission chain.

The transmission chain is sleeved on the first and second transmission sprockets. The diameter of the first transmission sprocket is larger than the diameter of the second transmission sprocket, so that the rotational speed of the material conveying component 5 is greater than the rotational speed of the stirring shaft 3.

[0050] As an alternative, the transmission assembly 6 includes a first transmission pulley, a second transmission pulley, and a transmission belt. The first transmission pulley is coaxially connected to one end of the material conveying component 5, the second transmission pulley is coaxially connected to one end of the stirring shaft 3, and the transmission belt is sleeved on the first transmission pulley and the second transmission pulley.

[0051] Furthermore, as above, the diameter of the first transmission pulley is larger than the diameter of the second transmission pulley, so that the rotational speed of the material conveying component 5 is greater than the rotational speed of the stirring shaft 3.

[0052] This invention can use either sprocket drive or belt drive to make the stirring shaft 3 and the material conveying component 5 rotate synchronously.

[0053] Furthermore, this utility model can be equipped with an openable and closable protective cover to seal the transmission component 6, and can also seal the reducer.

[0054] Example 3:

[0055] As another embodiment of this utility model, such as Figure 5 As shown, there are two discharge ports 42, each equipped with an opening and closing cover. A sleeve 8 is rotatably mounted on the conveying pipe 4, and the discharge ports 42 are located on the sleeve 8. The two discharge ports 42 are arranged in opposite directions along the vertical direction.

[0056] When this utility model has two discharge ports 42, either discharge port 42 can be closed by rotating the threaded opening and closing cover. Additionally, this utility model can switch the direction of the distal and proximal discharge ports 42 by using a sleeve 8, thus enabling material discharge from different positions.

[0057] Furthermore, a pre-tightening bolt can be installed on the sleeve 8. The pre-tightening bolt abuts against the outer wall of the conveying pipe 4 by rotating to pre-tighten the sleeve 8.

[0058] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
