Abstract
The utility model relates to an explosion-proof fan, which is characterized in that: one side of a fan cover is hinged on a case, and the other side of the fan cover is connected with a lock seat on the case through a lock catch; an air suction port on the case is connected with an air suction pipe, and an exhaust port is connected with an exhaust pipe; a motor is arranged outside the fan cover, and an impeller which is arranged at the inner side of the fan cover is connected with an output shaft of the motor; and a temperature sensor is arranged on the fan cover. The explosion-proof fan is convenient to disassemble, assemble and clean, and the working conditions of the explosion-proof fan can be monitored in real time; and the problems that the explosion-proof fan is difficult to disassemble and can not be fully cleaned, and the potential fire hazard problem can be effectively solved, and the safe and stable operation of the explosion-proof fan can be ensured.
Description
Technical field
The utility model relates to a kind of explosion-proof fan, belongs to the blower fan technical field.
Background technique
Explosion-proof fan can play the function of ventilation, smoke evacuation, blowdown.When explosion-proof fan is used in when discharging the indoor gas that has paint or a greasy dirt, having paint or greasy dirt sticks on the blade and motor of blower fan inside, if do not clear up for a long time, inner paint or greasy dirt can be long-pending more thick more, when the paint on the paint on the impeller or greasy dirt and the casing inside or greasy dirt are collided friction, will be on fire, cause fire.Common explosion-proof fan is when inner paint of cleaning or greasy dirt, and it is more time-consuming to open cover, and the cleaning space behind the apparatus lid opening is less, can't fully paint on the casing or greasy dirt be cleaned up.Common explosion-proof fan can't detect the paint that is bonded at its inside or greasy dirt temperature conditions and as when need cleaning, and can't put out burning things which may cause a fire disaster timely automatically.
Summary of the invention
The purpose of this utility model provides and a kind ofly convenient cleans, stable explosion-proof fan.
The utility model is that the technological scheme that achieves the above object is: a kind of explosion-proof fan, it is characterized in that: a side of described cover is hinged on the casing, opposite side is connected with lock on the casing by snap close, air sucking mouth on the casing is connected with suction pipe, exhaust port is connected with exhaust duct, motor is installed in the outside of cover, the impeller that is arranged on the cover inboard is connected with the output shaft of motor, and on the cover temperature transducer is installed.
Wherein: on the described exhaust duct fire extinguisher is installed.
Its cover of explosion-proof fan of the present utility model is hinged on the casing, and motor is installed in the outside of cover, impeller is arranged on the inside of cover again and is connected with the output shaft of motor, reach the effect of getting rid of oil smoke by the rotation of motor driving impeller, and when paint on the needs cleaning impeller or greasy dirt, only need easily with apparatus lid opening, make impeller exposed externally, because casing inside also has bigger space, parts such as casing and impeller can be cleaned up, motor is installed in the outside of cover simultaneously, has improved the working environment of motor, the performance that can keep the motor normal output.The utility model is installed in temperature transducer on the cover, can monitor temperature in real time attached to the paint or the greasy dirt of casing inside, when temperature raises, can in time signal be passed to fire extinguisher and put out burning things which may cause a fire disaster automatically, so just can avoid fire effectively.Explosion-proof fan of the present utility model is convenient to dismounting, cleaning, and its working condition can be monitored in real time, has solved the problem that the explosion-proof fan dismounting is difficult, clean incomplete and disaster hidden-trouble effectively, has guaranteed that it moves with security and stability.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1-casing, 2-temperature transducer, 3-cover, 4-motor, 5-impeller, 6-fire extinguisher, 7-exhaust duct, 8-suction pipe.
Embodiment
See shown in Figure 1, explosion-proof fan of the present utility model, comprise casing 1, motor 4 and impeller 5, one side of cover 3 is hinged on the casing 1, opposite side is connected with lock on the casing 1 by snap close, cover 3 and casing 1 boundary dimension sizableness, during blower fan work, the snap close of cover 3 is connected with lock on the casing 1 and is fitted in casing 1 end face, air sucking mouth on the casing 1 is connected with suction pipe 8, exhaust port is connected with exhaust duct 7, this suction pipe 8 is connected with paint chamber or oil smoke chamber and communicates, and exhaust duct 7 is connected with process chamber and communicates, or communicates with atmosphere, discharges outdoor by blower fan paint chamber or the indoor gas that has paint or greasy dirt of oil smoke.See shown in Figure 1ly, motor 4 of the present utility model is installed on the cover 3 and is positioned at the outside of cover 3, and the impeller 5 that is arranged on cover 3 inboards is connected with the output shaft of motor 4, by 5 rotations of motor 4 drives impeller, carries out exhaust.On the cover 3 of the present utility model temperature transducer 2 is installed, fire extinguisher 6 is installed on the exhaust duct 7, monitor the temperature of casing 1 inner paint or greasy dirt in real time by this temperature transducer 2, when temperature raises, can pass through temperature transducer 2 output signals, fire extinguisher 6 is opened automatically and put out a fire, in the casing 1 of explosion-proof fan, carry out sprinkling fire to exhaust duct 7 by fire extinguisher 6.
When the utility model cleans paint or greasy dirt when needs, the snap close on the cover 3 is removed from the lock on the casing 1, opened cover 3, can clean this moment to cover 3 inboards, casing 1 inside and impeller 5.
