Clear liquid turbidity detection equipment

Abstract

The invention discloses clear liquid turbidity detection equipment which is used for a ceramic fiber board preparation flocculation process and comprises: a net front box used for containing cotton pulp, wherein a light source used for emitting light to the inner wall of the opposite side is arranged on the inner wall of one side of the net front box, a light filtering assembly used for filtering light to obtain light with specific wavelength is arranged at the front end of the light source, a first photoelectric receiver and a second photoelectric receiver which are used for receiving light rays with specific wavelengths are arranged on the inner wall of the net front box, a first included angle is formed between the incident direction of the first photoelectric receiver and the emitting direction of the light source, and a second included angle is formed between the incident direction of the second photoelectric receiver and the emitting direction of the light source; and a processing device which is used for obtaining turbidity according to the optical signal and is in signal connection with the first photoelectric receiver and the second photoelectric receiver. The online detection of the flocculation state of the ceramic fiberboard preparation is realized, the detection period is shortened, the turbid phenomenon of the cotton pulp supernatant can be found in time, the influence on the forming is avoided, and the product production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of turbidity detection, in particular to a detection device for clear liquid turbidity. Background technique [0002] Ceramic fiber board is a new type of light-weight heat-insulating refractory product with excellent strength and heat-insulating performance, and is suitable for heat-insulation and heat-insulation in industries such as petrochemical, metallurgy, electric power and household appliances. [0003] At present, the production process of ceramic fiber boards usually uses organic binders, inorganic binders, ceramic fibers, and fillers to flocculate into cotton balls under the action of flocculants, which are formed by vacuum suction filtration or fourdrinier netting and then dried. A ceramic fiber board is produced. [0004] The main problem of this process is that the flocculated cotton mass will undergo irreversible depolymerization under continuous long-term stirring in the pulp storage tank, a...

Problems solved by technology

[0005] The existing supernatant turbidity detection method in the ceramic fiberboard molding process is to take the supernatant from the cotton pulp and put it into a turbidimeter for detection. It usually takes 0.5 to 1 hour from sampling to detection results, and the detection cycle is relatively short. Long, time-wasting; and the turbidity of the cotton pulp supernatant cannot be detected in time, which will affect the molding and cause great passiveness to continuous production.
