Abstract
The utility model discloses a frequency conversion control dryer, which comprises a heater, a drying tunnel and a fan and further comprises a temperature sensor and a frequency converter, wherein the temperature sensor is located inside the drying tunnel and is electrically connected with the frequency converter, and the frequency converter is electrically connected with the fan. According to the mode, the frequency conversion control dryer can achieve frequency conversion control, the fan is not required to be started frequently, the running current can be effectively reduced, energy can be saved, and the temperature control can be precise.
Description
Technical field
The utility model 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.
The utility model content
The technical problem that the utility model 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 utility model 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 utility model, said blower fan has two or more.
The beneficial effect of the utility model is: the utility model VFC dryer, realize VFC, and 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 the utility model VFC dryer one preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model embodiment 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.
The utility model VFC dryer 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 the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification 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 utility model.
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.
