Description
Technical field
The utility model belongs to reconstituted tobacoo production online detection and control technical field, is specifically related to a kind of device that wet end one way retention is detected and controls that is used for tobacco sheets by paper making method production.
Background technology
The tobacco sheets by paper making method production process comprises that mainly extraction concentrates, slurrying is manufactured paper with pulp and be coated with dry three parts.Wherein the section of manufacturing paper with pulp is the most serious operation of significant loss, this mainly is that (mainly be that offal, cigarette are broken, offal and add string) contains a large amount of fiber fines and heteroproteose cell because the reconstituted tobacoo slurry, but also added a certain amount of filler, thereby cause these tiny components when net part forming, to be easy to run off by mesh.A large amount of losses of tobacco sheets by paper making method slurry can cause following problem: 1, substrate ash content and brightness are on the low side, and fluctuation is big, and then have influence on the inherent sucking quality and the presentation quality of final products-thin slice; 2, machine water concentration is higher, and the cost of material load is big; 3, influence the runnability of paper machine.
Therefore, in view of the tiny component of tobacco sheets by paper making method slurry is many, easy characteristics that run off by the network of rivers detect the retention of slurry aborning and control is very important.The percentage of the inventory that adds during the retention of slurry is meant the inventory stayed in the paper web and produces.Various components in the paper making pulp can be calculated retention, but at the slurry compositing characteristic of reconstituted tobacoo and the specific (special) requirements on paper properties and the suction flavor, factory normally controls the total retention of one way and the one way ash retention of slurry.
As follows, formula (1) and formula (2) are the computing formula of total retention of slurry one way and one way ash retention:
The total retention of one way (FPOR)={ (C
h-C
w)/C
h} * 100%... ... .. (1)
One way ash retention (FPAR)={ (C
hA
h-C
wA
w)/C
hA
h} * 100% ... (2)
In the formula: C
hAnd C
wRepresent the concentration of solid content in head box and the white water chest respectively;
A
hAnd A
wRepresent the content of ashes of solid content in head box and the white water chest respectively.
At present, domestic tobacco sheets by paper making method producer normally adopts traditional off-line checking method, be that oven for drying method and high temperature sintering method are measured online concentration, white water consistency and content of ashes, and then calculate total retention of one way (FPOR) and one way ash retention (FPAR).These methods have following shortcoming: 1, the testing time is long.Testing time reaches several hours, and efficient is low, and data lag behind, and is difficult in time instruct produce; 2, poor accuracy.Because test process is more loaded down with trivial details, the manual operation error is difficult to avoid, thereby causes the accuracy of measurement data lower.
In addition, in the production of tobacco sheets by paper making method, in slurry, add electropositive macromolecule retention agent such as guar gum usually and improve retention.If fluctuation has taken place the retention of slurry in producing, the consumption of retention agent also should be done corresponding adjustment so, to guarantee the stable of retention.But, in actual production, the consumption of retention agent is generally regulated with flowmeter, when the retention fluctuation occurring, owing to be difficult in time know the definite numerical value and the scope (as mentioned above, the calculating of retention is to need the long period) of retention fluctuation, thereby can be more passive when regulating the flowmeter of retention agent, mainly go by rule of thumb to regulate, the accuracy of adjusting is difficult to guarantee, sometimes even can delay the best opportunity and production caused have a strong impact on.
The utility model content
Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of tobacco sheets by paper making method wet end one way retention online detection and control device, realize online timely detection and control, make and in time add retention agent in the production process, the stable retention that improves is guaranteed product quality.
The technical solution of the utility model is: a kind of host computer of tobacco sheets by paper making method wet end one way retention online detection and control device links to each other with the output of online flow sensor that is arranged on head box exit port place and online concentration sensor, host computer also be arranged on the plain boiled water conveyance conduit in online flow sensor and the output of online concentration sensor link to each other; The output of host computer links to each other with the input of the online volume control device of retention agent; The output that is arranged on the online flow sensor in the retention agent conveyance conduit links to each other with the input of the online volume control device of retention agent, and the output of the online volume control device of retention agent links to each other with the control end of Electromagnetic Flow control valve in being arranged on the retention agent conveyance conduit.Described online concentration sensor is a cutter formula concentration sensor.
The utility model is reasonable in design, and is simple in structure, implements easily, easy to operate, produces and stablizes, and can in time detect online data, and in time control improves retention, and product quality is improved.
