Embodiment 1

[0151] Initialize the measuring device for the concentration of tobacco sheet slurry, check whether the test components and filter press components are reset normally, whether there is a material cup left inside the movable platform, whether the waste liquid level in the waste liquid component exceeds the limit, and the pressure sensor and power switch. Whether the output is normal, whether the weighing balance is cleared, and whether the active platform is in the weighing station. After the measuring device is reset, everything is normal, and the measuring device will prompt "ready, ready to inject and measure" on the touch screen through the control part.

[0152] Open the safety cover, place an empty material cup on a rotating station of the movable plate of the movable platform, install a 600-mesh filter in the empty material cup, and cover the sealing piston pressure head, and send command signals to the control through the touch screen The control part sends a rotation s...

Embodiment 2

[0158] Take a certain amount of samples and divide them into 8 sub-samples, the weight of each sub-sample is M 0 , when the process value of the slurry concentration is 3.0%, the weight M after pressure filtration and dehydration is measured by this method. 1 , then these sub-samples are dried with an oven method to obtain the weight M after drying 2 , the correction coefficient A obtained by calculation is 0.471, and the specific data results are shown in Table 1.

[0159] Table 1

[0160]

[0161] Then, the oven method is used to obtain the weight M after drying 2 , and the slurry weight of the sub-sample is M 0 , through the slurry concentration W=M 2 / M 0 ×100%, the slurry concentration of the oven method was obtained by calculation. At the same time, the calculation formula of the correction coefficient A in the present invention is used to obtain the results of the slurry concentration. The specific results are shown in Table 2. It can be seen from Table 2 that...

Abstract

The invention provides a device for measuring the concentration of tobacco sheet pulp. The device comprises a testing part, a pressing and filtering part, a waste liquid part and a control part. The invention further provides a method for measuring the concentration of the tobacco sheet pulp by adopting the measuring device. According to the method and the device for measuring the concentration ofthe tobacco sheet pulp, on the basis of ensuring the measurement accuracy, the measurement time is greatly shortened, the measurement efficiency is improved, the blank of the industry in a tobacco sheet pulp concentration detection method is filled, and the method and the device have very important industrial popularization value.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet detection, relates to a method for measuring the pulp concentration of tobacco sheets and a measuring device thereof, and particularly relates to a method for rapidly measuring the pulp concentration of tobacco sheets and a measuring device thereof. Background technique [0002] In the process of manufacturing tobacco sheets by papermaking, the pulp concentration after pulping tobacco fibers is a key process parameter that affects the quality of the sheet. At present, there is no technical standard for measuring the pulp concentration of tobacco sheets in the tobacco industry, usually referring to the standards of the papermaking industry (" Determination of pulp slurry concentration "GB / T 5399-2004) to measure. According to the provisions of this standard document, the main steps for measuring pulp concentration are: ① sampling; ② pretreatment; ③ filter paper drying (to constant weight); ④ ...
