Abstract
The utility model discloses an exhaust device which aims at providing an energy-saving wind exhausting device and comprises an electric motor (1), a draught fan (2), a wind inlet tube (4), a wind outlet tube (5), a frequency conversion speed regulator (6), an I sealed strobe (7), an exhausting main tube (8), an II sealed strobe (9) and a plurality of wind transporting branch tubes (10, 11, 12) communicated with the wind transporting main tube (8). The utility model can be applied to the exhausting system of the clean and caloric exhaust.
Description
Technical field
The utility model relates to a kind of air exhausting device.
Background technology
An exhaust emissions operation is all arranged in the system that utilizes the steam indirect, finish this work by an air exhausting device as the starch drying machine of starch factory.Existing air exhausting device is made up of motor, air-introduced machine, blast pipe, exhaust duct and the valve for air exhaust that is arranged in the exhaust duct, described blast pipe and exhaust duct are arranged at the import and the outlet of described air-introduced machine respectively, tail gas after the motor-driven air-introduced machine separates drying materials in the starch drying machine sucks air-introduced machine by blast pipe, be discharged in the atmosphere by discharge pipe again, exhaust air rate is controlled by the open degree of valve in the work, but motor with same rated power running, has caused the loss of electric energy all the time; Because the existence of valve must have resistance, there is resistance that the loss of energy just must be arranged again.In addition, the tail gas of discharging from discharge pipe also has a large amount of waste heats (being generally about 50 ℃), and in winter, northern area particularly, and a lot of space requirement electric heater, hot water pipeline wait and warm oneself, and also do not have the device that directly adopts using waste heat from tail gas to warm oneself at present.So existing air exhausting device energy loss is very big.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of energy-conservation air exhausting device is provided.
The technical scheme that the utility model adopted is: the utility model comprises motor, air-introduced machine, blast pipe, discharge pipe, variable-frequency governor, described motor is connected with described air-introduced machine, described blast pipe is connected with the air inlet of described air-introduced machine, described discharge pipe is connected with the air outlet of described air-introduced machine, and described variable-frequency governor is connected by lead with described motor.
The utility model also comprises the defeated wind arm that I sealed gate, the defeated wind person in charge, II sealed gate and the some and described defeated wind person in charge are connected, described I sealed gate is arranged at the end of described discharge pipe, described defeated wind is responsible for and is connected with described discharge pipe, and described II sealed gate is arranged at described defeated wind and is responsible for anterior.
The beneficial effects of the utility model are: the utility model is owing to adopted the variable-frequency governor that is connected with motor, can make motor export different driving powers as required, saved valve for air exhaust simultaneously, also reduced the energy loss that causes owing to the valve resistance, thereby saved a large amount of electric energy; Again owing to be provided with that the defeated wind that is connected with discharge pipe is responsible for and defeated wind arm, defeated wind arm is fed the space that room etc. needs heating, just can directly adopt using waste heat from tail gas to warm oneself, need wait the expense of warming oneself with electric heater, hot water pipeline thereby saved.
Description of drawings
Fig. 1 is the structural representation of existing air exhausting device;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, existing air exhausting device is by motor 1, air-introduced machine 2, valve for air exhaust 3, blast pipe 4, discharge pipe 5, described motor 1 is connected with described air-introduced machine 2, described blast pipe 4 and described discharge pipe 5 are connected with the air inlet and the air outlet of described air-introduced machine 2 respectively, described valve for air exhaust 3 is arranged in the described blast pipe 4, motor 1 drives air-introduced machine 2 tail gas is sucked air-introduced machine 2 by blast pipe, be discharged to atmosphere by discharge pipe 5 again, this air exhausting device in use, motor 1 turns round with same rated power all the time, thereby has caused the loss of electric energy; Because the resistance of valve for air exhaust 3 exists, make the loss of energy more again.
As shown in Figure 2, the utility model comprises that motor 1, air-introduced machine 2, blast pipe 4, discharge pipe 5, variable-frequency governor 6, I sealed gate 7, defeated wind are responsible for 8, II sealed gate 9 reaches and the described defeated wind person in charge 8 defeated wind arms 10,11,12 that are connected, described defeated wind arm can increase and decrease quantity according to the heating needs, described motor 1 is connected with described air-introduced machine 2, described blast pipe 4 is connected with the air inlet of described air-introduced machine 2, described discharge pipe 5 is connected with the air outlet of described air-introduced machine 2, and described variable-frequency governor 6 and described motor 1 are connected by lead.Described I sealed gate 7 is arranged at the end of described discharge pipe 5, and described defeated wind is responsible for 8 and is connected with described discharge pipe 5, and described II sealed gate 9 is arranged at described defeated wind and is responsible for 8 front portions.The utility model in use, motor 1 can drive air-introduced machine 2 work to export different driving powers as required under the control of variable-frequency governor 6, thereby can save a large amount of electric energy, eliminate the energy loss that causes because of the resistance existence owing to having saved valve for air exhaust 3 again simultaneously; In the time need warming oneself winter, sealing I sealed gate 7 is opened II sealed gate 9 simultaneously, the defeated wind that is connected with air outlet 5 is responsible for 8 just can lead to needed space by defeated wind arm 10,11,12 etc. with the tail gas that has a waste heat, in the time need not warming oneself hot day, open I sealed gate 7 II envelope sealing closing gate 9 simultaneously, tail gas just can directly enter atmosphere.
