In some dusty working environments, dust removal and ventilation are particularly important. They can reduce dust concentration, eliminate potential hazards, improve the working environment for workers, and safeguard their health.

[0003] Existing dust removal and ventilation devices need further improvement in terms of flexibility, efficiency in dust removal and ventilation, and emergency response capabilities in the event of external power outages. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof dust removal and ventilation device that can be flexibly moved, perform efficient dust removal and ventilation operations, and continue to work for a period of time in the event of an external power outage, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An explosion-proof dust removal and ventilation device includes a housing. Two inner partitions are fixedly connected to the middle of the housing's interior. Bearing seats are provided on the outer surfaces of the inner partitions, and a first linkage shaft is installed within the rotating parts of the bearing seats. A fan blade is fixedly installed at one end of the first linkage shaft, and a second bevel gear is fixedly installed at the other end of the fan blade. Both second bevel gears are located between the two inner partitions. A bearing seat is provided on the top inner surface of the housing, and a second linkage shaft is installed within the rotating parts of the bearing seats. A first bevel gear is fixedly installed at one end of the second linkage shaft, located between the two second bevel gears and meshing with them. A battery and an emergency circuit board are installed on the bottom inner surface of the housing, both located between the two inner partitions.

[0007] By adopting the above technical solution, efficient dust removal and ventilation operations can be carried out, while also possessing emergency structure and function, making it highly practical.

[0008] Furthermore, a motor is fixedly installed on the upper surface of the housing, one end of the rotating shaft of the motor is connected to one end of the second linkage shaft through a coupling, and a protective cover is fastened to the outer cover of the motor.

[0009] By adopting the above technical solutions, effective explosion-proof protection operations can be carried out.

[0010] Furthermore, an electromagnetic relay and an inverter are installed on the bottom surface inside the enclosure. A movable cover is provided inside the enclosure, and a mounting groove is provided on the outer surface of the movable cover. A speed control switch is snapped into the inside of the mounting groove. An electrical connector is installed on the back of the enclosure, and the electrical connector, the speed control switch, and the motor are connected in series.

[0011] By adopting the above technical solution, the battery can be replenished with electrical energy when external power is supplied.

[0012] Furthermore, the electrical connector, emergency circuit board, and battery are electrically connected, the output terminal of the emergency circuit board, the electromagnetic relay, and the speed control switch are connected in series, and the electrical connector is electrically connected to the control terminal of the electromagnetic relay.

[0013] By adopting the above technical solution, the device can continue to be powered even when there is an external power outage.

[0014] Furthermore, a flange is fixedly connected to the inner wall of each end of the box, and an air filter element is fixedly installed on the flange. A second end cover and a third end cover are respectively fastened to the two ends of the box. A corrugated pipe is fixedly installed on the outer surface of the third end cover. Two exhaust pipes are fixedly connected to the outer surface of one side of the box, and a first end cover is fastened to the port of the exhaust pipe.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows the device to be moved to a designated location using a handle and casters. One end of the corrugated pipe is then connected to the air supply pipe. The motor is then started, driving the second linkage shaft to rotate. Under the linkage of the first and second bevel gears, the two first linkage shafts and two fan blades begin to rotate. The rotating fan blades allow indoor air to pass through the second end cover and enter the housing. During this process, the indoor air is filtered by one of the air filters and discharged through one of the exhaust pipes. The rotation of the other fan blade allows external air to enter the housing through the corrugated pipe, be filtered by another air filter, and then be discharged through another exhaust pipe. This entire process achieves efficient dust removal and ventilation. The device is also flexible and easy to use. Furthermore, because the motor is covered with a protective cover and the transmission components are located between two inner partitions, both the drive mechanism and transmission mechanism are within a sealed space, providing excellent explosion-proof performance. This effectively improves the device's practicality and applicability.

[0020] 2. When an external power source is connected, the emergency circuit board can effectively charge the battery. At the same time, the control terminal of the electromagnetic relay is energized and the electromagnetic relay is in an open circuit state, ensuring that the external power supply to the motor is stable without affecting the emergency circuit board. When the external power is cut off, the control terminal of the electromagnetic relay is de-energized, the electromagnetic relay closes, the circuit in the emergency circuit board switches, and the battery begins to supply power to the motor. This allows the device to continue to work for a period of time in the event of an external power outage, effectively improving the emergency performance and functionality of the device.
