The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is that the utility model is for the rotary concentration control system structural representation of paper pulp.
Refer to Fig. 1, the rotary concentration control system for paper pulp that the utility model provides comprises paper pulp pond 1, described paper pulp pond 1 is connected with disc mill 3 by fluffer 2, described paper pulp pond 1 is provided with concentration detection sensor 4 and PID adjusting apparatus 5, described concentration detection sensor 4 is positioned at slurry valve place, and described PID adjusting apparatus 5 is connected with the dilution water valve on paper pulp pond 1 by executing agency.
The rotary concentration control system for paper pulp that the utility model provides, the course of work is as follows: according to force balance principle, by labour, measure the concentration of slurry.Concentration detection sensor 4, as the detection means of adjuster, is converted to the signal of telecommunication pulp density data, supplies with PID adjusting apparatus 5, and described PID adjusting apparatus 5 passes through 0.3mm
2～1.5mm
2shielded multiconductor cable is connected with executing agency and exports 4～20mA conditioning signal.Concentration and valve position logger show the signal of telecommunication of concentration record, compare, and carry out computing through PID adjusting apparatus 5, and output 4-20MA conditioning signal is commanded executing agency's action, and realizes by DCS system.Executing agency regulates the aperture of dilution water valve, completes automatic adjusting task.
The rotary concentration control system for paper pulp that the utility model provides, the quality of raising paper product, meets the requirement that market and client are more and more higher, and optimized production process, improves paper machine efficiency simultaneously, reduces production costs.1, concentration detection sensor 4 is preferably mounted at pump, valve or elbow downstream, straight tube short distance (D is slurry pipe diameter for min=1m, many days 3D); 2, transmitter is in slurry valve or elbow upstream, straight length beeline (min=0.5m, many days 1.5D); 3, signal cable must be 0.3mm
2～1.5mm
2shielded multiconductor cable.4, alternating voltage scope is 90-130VAC or 190-260VAC.5, upper and lower limit concentration is: 4MA/00.00%-20MA/0.00%.6, signal stabilization damping time: 2～10s.Adopt of the present utility model as follows for the technique effect comparison before and after the rotary concentration control system of paper pulp:
1, making beating in early stage adds water and adds pulpboard beating in hydrabrusher, and initial stage beating well rear blowing, to paper pulp pond 1, is pumped to fluffer 2 by stock pump, and disc mill 3 carries out the use of beating paper supplying machine.Be subject to the water pump water yield, the impact of discharge time and operating personnel's sense of responsibility, the interior concentration in paper pulp pond 1 is extremely unstable, and then causes that slurry quality is unstable, and the detection data variation of the paper internal performance of producing is large.After the rotary concentration control system for paper pulp that employing the utility model provides, refining concentration is controlled, guaranteed the stable of refining concentration, the quality of defibrination is much improved, and the detection data trend of the paper internal performance of producing is stable.
2, starching in early stage, because being subject to the restriction of beating consistency, causes that the product that paper machine is produced quantitatively fluctuates large.After the rotary concentration control system for paper pulp that employing the utility model provides, in starching place, concentration is controlled, concentration stabilize, quantitatively also having stablized of product, be conducive to paper machine and produce normal and stablize, improved the efficiency of paper machine, promoted the quality of paper.
3, the water that concentration is controlled is that the plain boiled water to producing in paper machine production process utilizes again, energy-conservation, water saving, environmental protection.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; within not departing from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
