Abstract
The utility model relates to a drying device of a papermaking machine. The drying device comprises a box body with a closed periphery, a plurality of hot air rollers arranged in the box body, an air blower which is arranged at the bottom of one side of the box body and is connected to a hot air pipeline and an air pump arranged above the other side of the box body, wherein a variable frequency motor I for driving the air pump to rotate is arranged on the air pump; a variable frequency motor II for driving the air blower to rotate is arranged on the air blower; a humidity sensor is arranged at a joint of the air pump and the box body; the variable frequency motor I and the variable frequency motor II are respectively connected to a singlechip through a frequency converter I and a frequency converter II; the humidity sensor is connected to the singlechip. The humidity sensor monitors a humidity value at an outlet end in real time and feeds back the humidity value to the singlechip; the singlechip adjusts the rotating speeds of the variable frequency motor I and the variable frequency motor II through the frequency converter I and the frequency converter II according to the humidity, thus controlling the air pumping amount and the air blowing amount of the air pump and the air blower; therefore, effects of saving energy and reducing power consumption are achieved.
Description
Technical field
The utility model relates to pulp technology for making paper, is specifically related to a kind of drying unit.
Background technology
As everyone knows, paper is after the squeezer dehydration, the moisture of 60%-70% is approximately still arranged, the drying device reaches the finished product of the mass dryness fraction of 92%-95% after drying afterwards. and drying unit is that the moisture that utilizes dry hot blast to make to be attached to the paper on hot air roll becomes steam and extracts out by air exhauster, but the invariablenes turning speed of its air exhauster of existing drying unit and air blast is speed change as requested, cause the unnecessary consumption of electric weight.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of energy-conservation drying device of paper machine.
The utility model overcomes the technical scheme that its technical problem adopts:
This drying device of paper machine, comprise the casing that surrounding is airtight, be installed on the some hot air rolls in casing, the air exhauster that is installed on casing one side bottom and is connected in the air blast of hot air duct and is installed on casing opposite side top, variable-frequency motor I for driving air exhauster to rotate is installed on described air exhauster, the variable-frequency motor II of rotating for blower is installed on described air blast, described air exhauster and casing connecting portion are provided with humidity sensor, described variable-frequency motor I and variable-frequency motor II are connected in single-chip microcomputer by frequency converter I and frequency converter II respectively, described humidity sensor is connected in single-chip microcomputer.
In order to realize controlling the hot blast air inflow, on above-mentioned hot air duct, electrically-controlled valve is installed, described electrically-controlled valve is connected in single-chip microcomputer.
The beneficial effects of the utility model are: the dry-heat air that air blast is carried hot air duct is sent in casing, the lip-deep paper of hot air roll produces steam under the effect of hot blast, steam is because temperature is high, thereby upwards floating, and extract out by the air exhauster of top, the humidity value of the humidity sensor Real-Time Monitoring port of export, and feed back to single-chip microcomputer, single-chip microcomputer is regulated the rotating speed of variable-frequency motor I and variable-frequency motor II by frequency converter I and frequency converter II according to humidity, thereby control rate of air sucked in required and the blow rate required of air exhauster and air blast, thereby reach energy-conservation, reduce the effect of power consumption.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is control system theory diagram of the present utility model;
In figure, 1. casing 2. hot air roll 3. humidity sensor 4. air exhauster 5. variable-frequency motor I 6. air blast 7. variable-frequency motor II 8. electrically-controlled valve 9. hot air ducts.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing, be described further.
This drying device of paper machine, comprise the casing 1 that surrounding is airtight, be installed on the some hot air rolls 2 in casing 1, the air exhauster 4 that is installed on casing 1 one side bottoms and is connected in the air blast 6 of hot air duct 9 and is installed on casing 1 opposite side top, variable-frequency motor I 5 for driving air exhauster 4 to rotate is installed on described air exhauster 4, the variable-frequency motor II 7 of rotating for blower 6 is installed on described air blast 6, described air exhauster 4 is provided with humidity sensor 3 with casing 1 connecting portion, described variable-frequency motor I 5 and variable-frequency motor II 7 are connected in single-chip microcomputer by frequency converter I and frequency converter II respectively, described humidity sensor 3 is connected in single-chip microcomputer.The dry-heat air that air blast 6 is carried hot air duct 9 is sent in casing 1, the lip-deep paper of hot air roll 2 produces steam under the effect of hot blast, steam is because temperature is high, thereby upwards floating, and extract out by the air exhauster 4 of top, the humidity value of the humidity sensor 3 Real-Time Monitoring ports of export, and feed back to single-chip microcomputer, single-chip microcomputer is regulated the rotating speed of variable-frequency motor I 5 and variable-frequency motor II 7 by frequency converter I and frequency converter II according to humidity, thereby control rate of air sucked in required and the blow rate required of air exhauster 4 and air blast 6, thereby reach energy-conservation, reduce the effect of power consumption.
On above-mentioned hot air duct 9, electrically-controlled valve 8 is installed, described electrically-controlled valve 8 is connected in single-chip microcomputer.The humidity value of measuring according to humidity sensor 3, the unlatching amplitude of Single-chip Controlling electrically-controlled valve 8, to control the air inflow of dry-heat air, avoid the unnecessary waste of dry-heat air, further improved energy-saving effect.
