Description
Technical field
The present invention relates to wood-based plate manufacturing technology field, especially a kind of heat energy blower unit on staple fibre board assembly line.
Background technology
Staple fibre board production technology comprises raw material → chip → screen → wash → fiber preparation → dry → mat formation → precompressed → multi hot press → turnover panel cooling → saw sanction → centre to be deposited → sanding → warehouse-in etc., wet fiber wherein after fiber preparation will carry out drying, the thermal source that drying process needs is that the high-temperature gas introducing that heating center produces by the main induced draft fan by being located at heating center realizes, current main induced draft fan is by an Electric Machine Control, by two feeding fans, dried fiber is transported to A respectively respectively after fiber drying selection by winnowing, B two main lines are produced, there are the following problems for this Equipments Setting form: 1, when the market demand is not enough, when adopting single line to produce, obviously there is surplus in the energy of main induced draft fan conveying, cause the wasting of resources, 2, the Operational preparation phase before whole production line start, now heating center is in the temperature rise period, main induced draft fan is owing to can not start (if excess load is understood in main induced draft fan operation when temperature is low, easy burning motor and waste energy), therefore, when main induced draft fan cannot be opened, the heating-up time of heating center can be very long, wastes energy and affect production.
Summary of the invention
The object of this invention is to provide a kind of fibreboard production line heat energy blower unit, when it can solve heat energy surplus when current single line is produced, two-wire production, improve the problem of heating center's heating-up time length when output heat energy undersupply and Operational preparation.
In order to solve the problem, the technical solution used in the present invention is:
This fibreboard production line heat energy blower unit, comprise main induced draft fan, first motor, described main induced draft fan is connected by the first linkage unit with described first motor, also comprise the second motor, described second motor is variable-frequency motor, and described main induced draft fan is connected by the second gear unit with described second motor.
In above technical scheme, further scheme can be: described first linkage unit and the second linkage unit are that belt is connected.
Further: the rotating shaft of described main induced draft fan to be connected with vibration monitoring device and to rotate protection switch.
Further: described first motor is connected with the first current sensing means, described second motor is connected with the second current sensing means.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is when original motor drives main induced draft fan, increases a small-sized variable-frequency motor and jointly drives main induced draft fan, provide different drive arrangements according to the different conditions of production, thus the effect reaching saving production cost, raise the efficiency; 2, the present invention also increases current sensing means, installs vibration monitoring device and rotate protection switch at main induced draft fan shaft on every platform motor, improves the safety and reliability of whole dry blower unit.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Fibreboard production line heat energy blower unit as shown in Figure 1, comprise main induced draft fan 1 and the first motor 7, the rated power of the first motor 7 is 315KW, main induced draft fan 1 is fixed on support 13 by rotating shaft 10 and bearing block 2, the output shaft of the first motor 7 and rotating shaft 10 are fixed with belt pulley, and belt pulley is connected by belt; The rated power comprising the second motor 3, second motor 3 is 55KW, and the second motor 3 is variable-frequency motor, the second motor 3 and rotating shaft 10 is fixed with belt pulley, is connected between belt pulley by belt.
Owing to adding the second motor 3, main induced draft fan conveying capacity is increased, large problem is vibrated in the rotating shaft 10 that may there is main induced draft fan 1, the rotating shaft 10 of main induced draft fan 1 is connected with vibration monitoring device 8, and when vibration values is greater than 18mm/s, main induced draft fan closes setting shuts down; In addition, rotating shaft 10 is also provided with and rotates protection switch 9, when occurring that belt breaks, the situation such as the rotating shaft of main induced draft fan 1 10 disconnected or stall time, time delay setting in 5 seconds is shut down.
Owing to adding other second motor 3 in rotating shaft 10; motor is caused to burn out for preventing motor overload; the first current sensing means 12 is connected with at the first motor 7; second motor 3 is connected with the second current sensing means 11; and current of electric peak is set, when the electric current of the first motor 7, second motor 3 exceed the highest setting value time, time delay 1 second motor stopping; in addition, the excessive corresponding motor air switch of electric current also can trip protection.
After the drive unit of main induced draft fan 1 is born by the first motor 7 and the second motor 3, main induced draft fan 1 can realize following form control:
One, the temperature rise period: selection control mode is single action, drive main induced draft fan separately by the second motor 3, owing to being Frequency Converter Control, therefore this stage motor can adjust main induced draft fan rotating speed according to the anterior temperature of main induced draft fan 1 and reaches intensification object; Very large owing to running main induced draft fan 1 load when cold conditions, the second motor 3 easily overloads, and therefore must limit highest frequency when single action and prevent motor overload, and the highest frequency according to reality debugging this stage of setting is 23.5%.
Two, when single line is produced, use the incompatible reduction rotation speed of fan of middle low speed belt pulley set, select the second motor 3 single action to control, then operation main induced draft fan 1, then single action runs the first motor 7 and can achieve the goal;
Three, when two-wire is produced, because needs improve hot gas conveying capacity, select the second motor 3 coordinated signals, run the first motor 7, program setting first motor 7 start after time delay after 15 seconds the second motor 3 from motion tracking rotation speed of fan start, then according to the automatic tracing control of the magnitude of current after starting.
