Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an automatic mixing and dosing device of a coagulation test mixer. Background Art

[0002] The coagulation test is a classic verification test for "water pollution control testing" and is also used to evaluate the flocculation effect of water treatment agents. The principle is to add chemicals to the sewage and continuously stir it to destabilize the colloidal pollutants and suspended matter in the sewage. These particles then aggregate into micro-flocs during Brownian motion. This process involves two steps, coagulation and flocculation, collectively referred to as coagulation. Coagulation tests are typically conducted in a coagulation test mixer, which consists of several separate beakers. After adding the raw water for the test to the beakers, different proportions of water treatment agents are added. After periodic stirring, the amount of flocculent matter and the color of the water are observed, and water samples are taken to test turbidity.

[0003] The utility model patent with authorization announcement number CN215996520U discloses a coagulation test mixer, including a body, a stirring device and several test containers. The stirring device is provided on the body, and a cavity for accommodating the test container is also provided on the body. The stirring device includes a driving motor and several stirring paddles, and the stirring paddles are inserted into the test container. Transparent covers are provided on both sides of the cavity. An exhaust device is provided on the body, and the exhaust device is used to extract the gas in the cavity. A filtering device is provided at the connection between the exhaust device and the body. A control switch is provided on the body, and the control switch, stirring motor and exhaust device are electrically connected. The utility model is used for performance evaluation of water treatment agents, and can prevent sewage in the test container from emitting irritating gases during the test, thereby avoiding pollution of the surrounding environment.

The output end of the dosing cylinder 462 passes through the limit ring 471 and is fixedly connected to the piston plate 461. The area of the limit ring 471 is smaller than that of the piston plate 461. The top of the limit ring 471 is fixedly connected to an L-shaped rod 472. The L-shaped rod 472 passes through the top of the injection cylinder 43. The inside of the box body 1 A circular ring 473 is slidably connected along the vertical direction. A plurality of strip plates 474 are evenly arranged on the circular ring 473 along its circumference. The interior of the strip plates 474 is hollow.
