Abstract
The invention discloses a variable frequency control dryer which comprises a heater, a drying tunnel and a blower. The dryer also comprises a temperature sensor and a frequency converter, wherein the temperature sensor is arranged in the drying tunnel and is electrically connected with the frequency converter, and the frequency converter is also electrically connected with the blower. Through the mode, the variable frequency control dryer disclosed by the invention can realize the variable frequency control, the blower has no need of being started frequently, the running current is effectively reduced, the electricity and energy are saved, and the temperature control is accurate.
Description
Technical field
The present invention relates to a kind of VFC dryer.
Background technology
Dryer is used in the typing workshop, is mainly used in the oven dry of workshop lining.Mainly comprise heater, drying tunnel and one group of circulating fan; Circulating fan is sent into the heat that heater produces in the drying tunnel; Existing dryer mainly adopts the mode of direct start-up control, promptly reaches certain temperature in the drying tunnel, promptly stops the blower fan running; When the temperature in the drying tunnel is reduced to below the limit value, restart the blower fan running.Such control mode has following defective: a blower fan frequent starting, and starting current and revolution electric current are all bigger, influence equipment life; Temperature control inaccuracy in two drying tunnels.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of VFC dryer, the power and energy saving, and control is precisely.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of VFC dryer is provided; Comprise: heater, drying tunnel and blower fan; Said dryer also comprises temperature sensor and frequency converter, and said temperature sensor is positioned in the drying tunnel and with frequency converter and electrically connects, and said frequency converter also electrically connects with said blower fan.
In preferred embodiment of the present invention, said blower fan has two or more.
The invention has the beneficial effects as follows: VFC dryer of the present invention, realize VFC, blower fan need not frequent starting, effectively reduces revolution electric current, the power and energy saving, temperature control is precisely.
Description of drawings
Fig. 1 is the structural representation of VFC dryer one preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of VFC dryer; Comprise: heater, drying tunnel and blower fan; Said dryer also comprises temperature sensor and frequency converter; Said temperature sensor is positioned in the drying tunnel and with frequency converter and electrically connects, and temperature sensor converts the real-time temperature in the drying tunnel to the signal of telecommunication, and is transferred to frequency converter to above-said current signal; Said frequency converter also electrically connects with said blower fan, and frequency converter is handled calculating to the signal of telecommunication of temperature sensor input, according to result of calculation the rotating speed of blower fan is controlled.
With the dryer that 12 7.5KW blower fans are arranged is example, adopts traditional direct start-up control mode, and revolution electric current reaches 140A; Adopt VFC, revolution electric current is reduced to 100A, annual about 120,000 degree that can economize on electricity.
VFC dryer of the present invention is realized VFC, and blower fan need not frequent starting, effectively reduces revolution electric current, the power and energy saving, and temperature control is precisely.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
Claims (2)
1. VFC dryer; Comprise: heater, drying tunnel and blower fan is characterized in that said dryer also comprises temperature sensor and frequency converter; Said temperature sensor is positioned in the drying tunnel and with frequency converter and electrically connects, and said frequency converter also electrically connects with said blower fan.
2. VFC dryer according to claim 1 is characterized in that said blower fan has two or more.
