[0005] 2. Traditional mixing devices usually do not take into account the situation that some flocculants will settle to the bottom during the mixing process of wastewater treatment agents. This situation results in poor mixing effect of the equipment and makes it impossible to fully stir and mix the settled agents. Utility Model Content

[0006] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a wastewater treatment agent addition and mixing device to solve the problems existing in the prior art.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A wastewater treatment agent addition and mixing device includes a primary stirring tank and a mixing tank. The primary stirring tank is equipped with a first cover plate, and a first motor is installed on the first cover plate. A first rotating shaft is installed on the power output end of the first motor, and stirring blades are installed on the first rotating shaft. The primary stirring tank is connected to a connecting pipe, and the mixing tank is equipped with a second cover plate. The connecting pipe is connected to the second cover plate, and a first valve is installed on the connecting pipe.

[0009] The mixing tank is equipped with a support base, the support base is equipped with a support frame, the support frame is equipped with a second motor, the power output end of the second motor is equipped with a first linkage rod, the first linkage rod is fixedly equipped with a second rotating shaft, the second rotating shaft is equipped with an upward auger, the mixing tank is equipped with a discharge pipe, and the discharge pipe is matched with a second valve.

[0010] Further specifying, the first linkage rod is equipped with a drive gear, which is matched with a transmission chain. The mixing tank is equipped with a second linkage rod, which is matched with a driven gear that matches the transmission chain. The second linkage rod is fixedly equipped with a third rotating shaft, which is equipped with a downward-pressing auger. This structural design enables a counter-clockwise liquid flow and mixing effect within the mixing tank, pushing the settled reagent to the top for mixing, resulting in better mixing performance.

[0011] Furthermore, the first cover plate is provided with a feed inlet, and a third cover plate is installed on the feed inlet. This structural design allows the primary mixing tank to add reagents through the feed inlet without removing the first cover plate, preventing dust and other contaminants from entering the primary mixing tank. The third cover plate further enhances the dustproof effect.

[0012] The present invention has the following advantages:

[0013] This invention, by setting up a primary stirring tank and a mixing tank, enables the agent to be mixed multiple times through the primary stirring tank and the mixing tank, thus improving the mixing effect of the equipment.

[0014] This invention, by setting up an upward-pushing auger, enables the medicine that has sunk to the bottom to be pushed up, thus avoiding the situation where the medicine sinks to the bottom and the stirring effect is poor.

[0015] This invention, by setting up an upward-pushing auger and a downward-pressing auger, enables the mixing tank to achieve a counter-clockwise liquid flow and mixing effect, pushing the settled reagent to the top for better mixing. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, a wastewater treatment agent addition and mixing device includes a primary mixing tank 1 and a mixing tank 2. The primary mixing tank 1 is equipped with a first cover plate 3, the first cover plate 3 is equipped with a first motor 4, the power output end of the first motor 4 is equipped with a first rotating shaft 5, the first rotating shaft 5 is equipped with a stirring blade 6, the primary mixing tank 1 is connected to a connecting pipe 7, the mixing tank 2 is equipped with a second cover plate 25, the connecting pipe 7 is connected to the second cover plate 25, and the connecting pipe 7 is matched with a first valve 8.

[0024] The mixing tank 2 is equipped with a support base 9, the support base 9 is equipped with a support frame 10, the support frame 10 is equipped with a second motor 11, the power output end of the second motor 11 is equipped with a first linkage rod 12, the first linkage rod 12 is fixedly equipped with a second rotating shaft 13, the second rotating shaft 13 is equipped with an upward auger 14, the mixing tank 2 is equipped with a discharge pipe 15, and the discharge pipe 15 is matched with a second valve 16.

[0025] Working principle explanation:

[0026] Example 1, as Figure 1 , Figure 2 and Figure 3As shown, the reagents to be mixed are stirred and mixed through the primary stirring tank 1 and the mixing tank 2. It is worth noting that the reagents first enter the primary stirring tank 1, the first motor 4 is started, the power output end of the first motor 4 drives the first rotating shaft 5 to rotate, the rotation of the first rotating shaft 5 drives the stirring fan blades 6 to move and mix the reagents. Then the first valve 8 is opened to allow the pre-mixed reagents to enter the mixing tank 2 through the connecting pipe 7. The second motor 11 is started, the power output end of the second motor 11 drives the first linkage rod 12 to rotate, the rotation of the first linkage rod 12 drives the second rotating shaft 13 to rotate, which in turn drives the upward auger 14 to operate. The upward auger 14 creates an upward thrust in the mixing tank 2, pushing the reagents at the bottom to enhance the mixing effect and make the equipment mix better. Finally, the second valve 16 is opened to allow the mixed reagents to be discharged through the discharge pipe 15.

[0027] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: A drive gear 17 is installed on the first linkage 12, and a transmission chain 18 is matched and installed on the drive gear 17; a second linkage 19 is installed on the mixing tank 2, and a driven gear 20 matching the transmission chain 18 is installed on the second linkage 19; a third rotating shaft 21 is fixedly installed on the second linkage 19, and a downward auger 22 is installed on the third rotating shaft 21. It is worth noting that when the medicine enters the mixing tank 2 and the second motor 11 is started, the power output end of the second motor 11 drives the first linkage 12 to rotate. The rotation of rod 12 drives the second rotating shaft 13 to rotate, which in turn drives the upward auger 14 to operate. The rotation of the first linkage rod 12 drives the drive gear 17 installed on it to rotate. The rotation of the drive gear 17 drives the transmission chain 18 to move, which in turn drives the driven gear 20 to rotate. The rotation of the driven gear 20 drives the second linkage rod 19 to rotate. The third rotating shaft 21, which is fixedly installed on the second linkage rod 19, follows the rotation, which in turn drives the downward auger 22 to operate. This structural design can create a counterclockwise liquid flow rotation mixing effect in the mixing tank 2, pushing the settled reagent to rise and mix, making the equipment mix better.

[0028] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment adds the following structure to the original embodiment 1: the first cover plate 3 is provided with a feed inlet 23, and a third cover plate 24 is installed on the feed inlet 23. It is worth noting that when it is necessary to add the medicine into the primary mixing tank 1, the third cover plate 24 is opened to allow the medicine to enter the primary mixing tank 1 through the feed inlet 23, and then the third cover plate 24 is closed. This structural design allows the primary mixing tank 1 to add medicine through the feed inlet 23 without removing the first cover plate 3, preventing dust and other particles from entering the primary mixing tank 1. The third cover plate 24 further achieves the effect of dust prevention.
