Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality acidity and alkalinity detection device. Background Art

[0002] Industrial wastewater contains a variety of hazardous substances. The components in the wastewater need to be tested before discharge. Water quality testing includes many items, with pH testing being the most common. Commonly used pH testing equipment uses a burette to absorb the water to be collected and then drops it on a pH test paper for display. However, this practice often results in wastewater dripping onto the hands of the tester.

[0003] To this end, we have developed a new water pH testing equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a water quality pH detection device.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a water quality pH detection equipment, including a catheter, one end of the catheter is connected to a sampling bucket, the other end of the catheter is connected to a tee, one end of the tee is equipped with a first spiral valve, the end of the first spiral valve away from the tee is connected to a liquid collecting catheter; the bottom end of the tee is connected to a connecting pipe, the top end of the connecting pipe is equipped with a second spiral valve; the bottom end of the connecting pipe is connected to a test paper positioning mechanism, and the bottom end of the test paper positioning mechanism is equipped with a liquid collecting bottle.

[0006] Furthermore, one end of the liquid collecting conduit is connected to one end of the first spiral valve, and the bottom end of the liquid collecting conduit is connected to a sampling bag.

[0007] Furthermore, the test paper positioning mechanism includes a locator body, a top connecting seat and a bottom connecting seat are respectively provided at the center of the top and bottom of the locator body, a test paper plug-in slot is opened at the center of the front end of the locator body, and a silicone sealing ring is provided at the front end opening of the locator body.

[0008] Furthermore, the locator body is an elongated block structure as a whole, and the top connecting seat and the bottom connecting seat are both connected to the test paper insertion slot.

[0009] Furthermore, the width of the center of the test paper insertion slot is greater than the width of the test paper.

[0010] The utility model has the following beneficial effects:

[0011] The utility model provides a water quality pH detection device, in which a test paper positioning mechanism is used for the insertion and positioning of the test paper, and an interference fit is adopted between the test paper and the test paper insertion slot, which can ensure the stability of the test paper in the inserted state and prevent it from automatically slipping off, so as to facilitate subsequent detection. The silicone sealing ring arranged at the front end opening of the locator body can realize an auxiliary sealing effect to prevent the sampled water from overflowing along the front end opening of the test paper insertion slot.
