Description

(54) МУТНОМЕР(54) MUTNOMER

1one

Изобретение относитс  к исследованию физических свойств веществ и может быть использовано, например, дл  фотометрического контрол  зольности отходов флотации угл  при измерении содержани  твердой фазы в диапазоне от 10 до 50 г/л.The invention relates to the study of the physical properties of substances and can be used, for example, for photometric control of the ash content of coal flotation waste when measuring the solids content in the range from 10 to 50 g / l.

Известен мутномер, содержащий источник излучени , кювету и два фотоприемника, св занных со входами измерительного блока 1.A turbidity meter is known which contains a radiation source, a cuvette and two photodetectors associated with the inputs of the measuring unit 1.

Наиболее близким техническим решением к предлагаемому  вл етс  мутномер, содержащий источник излучени , установленные по ход5 излучени  оптическую систему, кювету и два фотоприемника, св занных со входами измерительного блока 2.The closest technical solution to the present invention is a turbidity meter containing a radiation source, an optical system installed along the radiation path5, a cuvette and two photodetectors connected to the inputs of the measuring unit 2.

Недостатокизвестного устройства состоит в высокой погрещности измерени  зольности отходов флотации в разбавленных пульпах с высоким коэффициентом поглощени , так как между отраженным световым потоком и содержанием твердой фазы при посто нной зольности существует нелинейна  св зь, котора  особенно сильно прот  вл етс  при изменении содержани  твердой фазы от 10 до 50 г/л, что обусловливает неоднозначность измерений зольности непосредственно в потоке пульп.A disadvantage of the known device is the high accuracy of measuring the ash content of flotation waste in diluted pulps with a high absorption coefficient, since there is a non-linear relationship between the reflected luminous flux and the solids content at a constant ash content, which is particularly pronounced when the solids content varies from 10 up to 50 g / l, which causes the ambiguity of ash measurements directly in the pulp stream.

Цель изобретени  - повышение точности .The purpose of the invention is to improve accuracy.

Поставленна  цель достигаетс  тем, что в мутномере, содержащем источник излучени , установленные по ходу излучени  Оптическую систему, кювету и два фотоприемника , св занных со входами измерительного блока, задн   стенка кюветы выполнена в виде матированной пластины, в центре коfQ торой на оптической оси источника излучени  расположен один фотоприемник, а другой фотоприемник расположен под углом к передней стенке кюветы.The goal is achieved by the fact that in a turbidity meter containing a radiation source, installed along the optical path, the optical system, the cuvette and two photodetectors connected to the inputs of the measuring unit, the back wall of the cuvette is made in the form of a matted plate, in the center of the cavity on the optical axis of the radiation source one photodetector is located, and the other photodetector is located at an angle to the front wall of the cuvette.

На чертеже изображена функциональна  схема предлагаемого мутномера.The drawing shows the functional diagram of the proposed mutomer.

Мутномер содержит источник 1 излуче15 ни , формирующую оптическую систему 2, например конденсорную линзу, фотоприемник 3, расположенный под углом к передней стенке кюветы 4, за которой расположена контролируема  среда 5, и матированную Mutnomer contains a source of radiation 1, which forms the optical system 2, for example, a condenser lens, a photodetector 3 located at an angle to the front wall of the cuvette 4, behind which the controlled medium 5 is located, and matted

20 пластину б, установленную параллельно передней стенке кюветы 4, в центре которой находитс  второй фотоприемник 7. Измерительный усилитель 8, усилитель 9 с регули20 plate b, mounted parallel to the front wall of the cuvette 4, in the center of which is the second photodetector 7.
