[0002] In the mixing room for water-based and powdered chemicals, a water treatment chemical mixing device is used.
[0003] Existing water treatment chemical mixing devices cannot scrape off residual chemical clumps on the side walls of the mixing chamber during use, making it difficult to clean the mixing chamber. Secondly, relying on a single impeller can easily create dead zones in the liquid flow, resulting in insufficient chemical dispersion. Therefore, there is an urgent need for a water treatment chemical mixing device to solve the above technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a water treatment agent mixing device to solve the problems mentioned in the background art. In use, the existing water treatment agent mixing devices cannot scrape off the residual agent clumps on the side wall of the mixing chamber, which makes it difficult to clean the mixing chamber. Secondly, relying on a single blade can easily create dead zones in the liquid flow, resulting in insufficient agent dispersion.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A water treatment agent mixing device includes a support frame with feet connected to both sides of its bottom. A mixing chamber is located inside the support frame, with its top extending upwards through the top of the support frame. A first inlet is located at the upper left end of the mixing chamber, and a second inlet is located at the upper right end. A discharge port is located at the bottom of the mixing chamber, with its lower end extending downwards through the bottom of the support frame. A valve is installed on the discharge port. A motor is installed at the center of the top of the mixing chamber, with its output shaft passing through the top of the mixing chamber and connected to a stirring shaft via a coupling. A left scraper and a right scraper are respectively installed on the left and right side walls of the mixing chamber. Spiral blades and turbine blades are alternately arranged from top to bottom on the stirring shaft. A top support rod is installed near the upper end of the stirring shaft, and a bottom support rod is connected to the bottom of the stirring shaft. The left and right ends of the top and bottom support rods are connected to the left and right scrapers, respectively.
[0007] In a preferred embodiment of this invention, the right scraper is in contact with the inner wall of the mixing chamber, but not connected to it.
[0008] In a preferred embodiment of this invention, the left scraper is in contact with the inner wall of the mixing chamber, but not connected to it.
[0009] In a preferred embodiment of this invention, the top support rod is fixedly connected to the stirring shaft.
[0010] In a preferred embodiment of this invention, the bottom support rod is fixedly connected to the stirring shaft.
[0011] As a preferred embodiment of this utility model, the left scraper and the right scraper are arranged symmetrically about the stirring shaft.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, by setting up a left scraper, a right scraper, a top support rod, and a bottom support rod, allows the motor to be started when the mixing chamber needs to be cleaned. The motor then drives the left and right scrapers to rotate via the top and bottom support rods, thereby scraping off residual drug clumps on the side walls of the mixing chamber and reducing the difficulty of cleaning the interior of the mixing chamber.
[0014] 2. This utility model uses alternating spiral blades and turbine blades arranged from top to bottom on the stirring shaft, so that the spiral blades drive the liquid to circulate up and down, and the turbine blades generate radial shear force, thereby eliminating the mixing dead zone through the bidirectional flow field.

[0021] Please see Figure 1-3 A water treatment agent mixing device includes a support frame 1, with feet 2 connected to both sides of the bottom of the support frame 1. A mixing chamber 3 is disposed inside the support frame 1. The top of the mixing chamber 3 passes through the top of the support frame 1 and extends upwards. A first inlet 4 is opened at the upper left end of the mixing chamber 3, a second inlet 5 is opened at the upper right end of the mixing chamber 3, and a discharge port 6 is opened at the bottom of the mixing chamber 3. The lower end of the discharge port 6 passes through the bottom of the support frame 1 and extends downwards. A valve 7 is installed on the discharge port 6. A valve 7 is installed at the middle of the top of the mixing chamber 3. The mixing chamber is equipped with a motor 8. The output shaft of the motor 8 passes through the top of the mixing chamber 3 and is connected to a stirring shaft 10 via a coupling 9. A left scraper 16 and a right scraper 13 are respectively installed on the left and right side walls of the mixing chamber 3. Spiral blades 11 and turbine blades 12 are alternately arranged from top to bottom on the stirring shaft 10. A top support rod 14 is installed at the upper end of the stirring shaft 10, and a bottom support rod 15 is connected to the bottom of the stirring shaft 10. The left and right ends of the top support rod 14 and the bottom support rod 15 are respectively connected to the left scraper 16 and the right scraper 13.
[0022] The right scraper 13 is in contact with the inner wall of the mixing chamber 3, but not connected to it.
[0023] The left scraper 16 is in contact with the inner wall of the mixing chamber 3, but not connected to it.

[0027] The working principle and usage process of this utility model are as follows: First, the liquid medicine and the powder medicine are poured into the mixing chamber 3 from the first inlet 4 and the second inlet 5 respectively. Then, the motor 8 is started to drive the stirring shaft 10 on the coupling 9 to rotate. The rotating stirring shaft 10 drives the spiral blade 11 and the turbine blade 12 on it to rotate, so that the spiral blade 11 pushes the liquid up and down to circulate, and the turbine blade 12 generates radial shear force. The mixing dead zone is eliminated through the bidirectional flow field. When it is necessary to discharge the mixed medicine after the mixing is completed, the valve 7 on the discharge port 6 is opened and the medicine is discharged through the discharge port 6.
[0028] When it is necessary to clean the mixing chamber 3, the motor 8 is started and the left scraper 16 and right scraper 13 are rotated through the top support rod 14 and the bottom support rod 15, thereby scraping off the residual drug clumps on the inner wall of the mixing chamber 3, reducing the difficulty of cleaning the inside of the mixing chamber 3.
