Potassium permanganate index analyzer

Abstract

The embodiment of the invention discloses a potassium permanganate index analyzer. The potassium permanganate index analyzer comprises a digestion cup body, a heating module arranged on the outer sideof the digestion cup body, and a temperature controller connected with the heating module. The heating module comprises a heating belt which is attached to and wound on the outer side of the digestion cup body at equal intervals, a plurality of convex points which are used for fixing the heating belt and are arranged on the outer side of the digestion cup body, and two wrapping posts. The starting end and the terminal end of the heating belt are respectively connected with the corresponding wrapping posts through wiring terminals; the first type of convex points are arranged on the left sideand the right side of the digestion cup body, the convex points on the same side are distributed at equal intervals, the second type of convex points are arranged below a starting winding ring and a stopping winding ring of the heating belt, the convex points on the same horizontal plane are symmetrically distributed on the front side and the rear side of the digestion cup body, and the number ofthe convex points is determined by the length and width of the heating belt. And the temperature controller controls the heating power of the heating module according to a real-time temperature of a reaction solution and a standard temperature curve. According to the invention, high-efficiency and accurate water quality detection can be realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of surface water quality detection, in particular to a potassium permanganate index analyzer. Background technique [0002] With the rapid development of industry, more and more industrial water and industrial waste are discharged, rivers and lakes are polluted frequently, and the water quality of daily life is gradually deteriorating. How to monitor water quality in a safe, reliable and easy-to-operate manner has become an urgent problem to be solved. . [0003] As one of the main indicators of surface water quality, permanganate index can effectively characterize the degree of organic pollution in water. The water quality permanganate index is measured by adding 100mL sample + 5mL sulfuric acid + 10mL potassium permanganate into a 250mL conical flask, putting the conical flask into a water bath for 30 minutes, adding 10mL sodium oxalate, and then using high Potassium manganate w...

Problems solved by technology

However, the heating mode of the digestion cup in the related art has a poor temperature control effect, and the water quality is heated unevenly. For example, aluminum blocks or heating wires are used, the processing technology is complicated, the safety and reliability are not high, and the oxidation rate of organic matter is different from the national standard. rate, resulting in unstable or inaccurate instrument measurements
