Technical Field

[0001] The utility model relates to the technical field of water supply plant detection, in particular to a coagulation test auxiliary device capable of realizing temperature regulation. Background Art

[0002] In the water treatment process of water supply plants, the amount of coagulant, the type of coagulant and the ratio of different coagulants have always been important factors affecting the water treatment effect and the quality of water leaving the water supply plant. In order to achieve more accurate and efficient coagulant addition, water plants usually conduct small coagulation tests to guide the actual coagulant addition value. In recent years, with the continuous development of the drinking water industry, the country's requirements for the quality of water leaving the water supply plant have been continuously improved, and the latest "Sanitary Standards for Drinking Water" has put forward further requirements for the quality of water leaving the water supply plant.

[0003] In the face of the ever-changing era, the challenges faced by water treatment in water plants are increasing. Due to the water volume restrictions of the South-to-North Water Diversion Project, water treatment plants in the north can only switch to the Luanhe River water source in winter. The resulting low temperature and low turbidity problems have plagued water plants for many years. Considering that coagulation tests in water plants are usually conducted indoors, it is difficult to truly simulate the coagulation effects in different seasons, especially in winter, due to the influence of room temperature. In addition, most of the six-unit mixers used for coagulation tests on the market do not have temperature control functions, or only have warm water bath functions. Utility Model Content

The test cups 5 are provided with a sampling port 51 and an emptying port 52. The emptying port 52 is arranged at the bottom of the side of the test cup 5. The sampling port 51 is arranged above the emptying port 52 and is in the same straight line as the emptying port 52. The sampling port 51 and the emptying port 52 make the inside and outside of the test cup 5 communicate with each other. The test cup 5 is also provided with an output tube, which includes a first output tube 53 and a second output tube 54. One end of the first output tube 53 and the second output tube 54 are connected to the sampling port 51 and the emptying port 52 respectively.

[0027] In this embodiment, six test cups 5 are provided as six control groups. Each test cup 5 is set to 1000 mL. The test cup 5 is fixed inside the storage cylinder 1 through the first output tube 53 and the second output tube 54. Even if excess water is placed in the storage cylinder 1, the test cup 5 will not float up and down due to buoyancy or move in the cylinder.

[0028] Specifically, a heating rod 6 is provided inside the storage cylinder 1 and is fixed at the left side inside the storage cylinder 1 by a fixing buckle, so as to increase the water temperature inside the storage cylinder 1 .

[0031] The working principle of this embodiment:

[0032] First, water is poured into the storage cylinder 1. The water level does not exceed the height of the cup mouth of each test cup 5 to prevent the water in the storage cylinder 1 from flowing into the test cup 5. The heating rod 6 is turned on to increase the temperature of the water in the storage cylinder 1. When the temperature is too high, the peristaltic pump 8 is turned on to suck the water in the storage cylinder 1 into the chiller 7 through the first connecting pipe 9. The cooled water flows from the chiller 7 to the storage cylinder 1 through the second connecting pipe 10. The water temperature in the storage cylinder 1 can be observed through a display screen 12 connected to a temperature sensor 11. This process completes the water heating and cooling cycle. The water temperature control range is between 0℃-30℃, and the coagulation test is carried out within this temperature range.
