All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1, 2, 5 and 6, an automatic dedusting apparatus for a large-scale workshop includes an air duct 08, a motor 21 is fixedly connected to the interior of the air duct 08 through a fixing frame, fan blades 22 are fixedly connected to an output shaft of the motor 21, a filter box 03 is communicated with the air duct 08, a filter screen 24 is connected to the interior of the filter box 03 in a limiting and sliding manner, the filter screen 24 vertically penetrates through the filter box 03, a hollow ball 25 is fixedly connected to a side surface of the inner wall of the filter box 03, which is located on the filter screen 24 and close to the air duct 08, a variable frequency controller 09 for controlling the rotation speed of the motor 21 is arranged on the air duct 08, and a locking device for limiting the filter screen 24 on the filter box 03 is further arranged on the filter box 03.

The during operation of motor 21 can drive flabellum 22 through the output shaft and rotate when flabellum 22 fast turn round, can take out the air current in the dryer 08 from the direction that is close to rose box 03 towards the direction of keeping away from rose box 03 and send, thereby can take out air current in the rose box 03 in the air cylinder 08, thereby the air can flow into rose box 03 through the right side of rose box 03 in, rethread rose box 03 flows into in the dryer 08, when the air current passes through the filter screen 24 in the rose box 03, a large amount of dust and the dust that contain in the air can be filtered to filter screen 24, thereby play the function of dust fall.

Owing to be provided with inverter controller 09, inverter controller 09 can control the slew velocity of motor 21 and suddenly change, can set for one big or little two fixed values, makes inverter controller 09 control motor 21 pivoted speed work back and forth between two slew velocity numerical values to the air that the right side flowed into in rose box 03 can suddenly change greatly, no matter the flow velocity grow or reduce of air current, the filtering capability of filter screen 24 still can be going on continuously. Due to the hollow ball 25, when the air flow flows towards the air duct 08 through the filter box 03, the hollow ball 25 can be blown to float towards the air duct 08, the air flow generated by the fan blades 22 is small and large, when the air flow is large, the hollow ball 25 can obliquely float towards the air duct 08, but when the air flow is small, the power of the air flow is not enough to enable the hollow ball 25 to float, so that the hollow ball 25 can reset towards the initial position under the action of gravity, but due to the inertia effect, the hollow ball 25 cannot stop in a vertical state, so that the hollow ball can collide against the filter screen 24, the function of slightly knocking the filter screen 24 is achieved, the hollow ball 25 can be reduced along with the continuous increase of the air flow, the filter screen 24 can be continuously knocked, and the dust adsorbed on the filter screen 24 can be shaken off.

When current device carries out filterable, often can adopt invariable wind speed to induced draft and filter, but because the existence that wind-force lasts, the dust of being inhaled the device can support on the filter screen under the thrust effect of wind-force to get off the dust for a long time and can be constantly piled up on the filter screen, thereby the filtering capability of filter screen can gradual reduction. However, in the invention, the air draft is in a large and small mode, when the dust is sucked into the filter box 03 by large wind force and is attached to the filter screen 24, the wind force is reduced, so that the effect of the large wind force is lost, part of the dust loses the supporting force of the suction force, and the dust directly falls down, especially the dust with large particles, so that the filter screen 24 can continuously keep a high-efficiency filtering effect.

When wind-force reduces, some dust can drop, but still have some dust to be connected on the filter screen, but when wind-force reduces, clean shot 25 also can strike on filter screen 24 to shake a large amount of dust from filter screen 24 and shake off, thereby can play the drop that promotes the dust, thereby can further improve filter screen life.

Because the wind power is suddenly reduced, even when the wind power is small, the airflow still flows towards the inside of the filter box 03, so that the power consumption of the motor 21 can be reduced, and the airflow flowing can promote dust to quickly flow into the filter box 03 for filtering when the wind power is increased.

When the filter screen 24 is clogged with dust, its filtering function is reduced, but the wind generated by the rotation of the fan 22 driven by the motor 21 is still within the set value, so that the suction force generated by the motor is not changed in this interval at the time of the maximum value and the minimum value and at the time of the value between the maximum value and the minimum value. Therefore, when the filtering function of the filter screen 24 is reduced, the air permeability is reduced, so that the suction force of the wind generated by the fan blades 22 on the air duct 08 and the negative pressure action inside the filter box 03 is raised, so that the hollow valve 15 moves in the direction of the filter box 03 in the negative pressure cylinder 11, when the hollow valve 15 moves to the position where the negative pressure cylinder 11 is closest to the filter box 03, the lock head 19 slides in the lock seat 17 by pulling the pull rope 12 through the slide rod 14, so that the lock head 19 moves out of the first scraper 26, at this time, the limiting action of the lock head 19 is lost, under the action of gravity, the auxiliary filter plate 07 and the filter screen 24 move downwards simultaneously, the filter screen 24 moves out of the filter box 03, the auxiliary filter plate 07 moves into the filter box 03, under the action of the first spring 18, the slide rod 14 is pushed to reset, so that the pull rope 12 is released, so that the second spring rod 20 can push the lock head 19 to be clamped in the first scraper 26 of the auxiliary filter plate 07, therefore, the filter screens are switched, the filter screens 24 can be taken out for sufficient cleaning, the filter screens are inserted into the limiting plate 06 again after the cleaning is finished, and after the filtering capacity of the auxiliary filter plate 07 is reduced, the auxiliary filter plate 07 and the filter screens 24 can repeat the replacement action. Compared with the prior art, the automatic filter screen replacing device can realize the function of automatically replacing the filter screen when the filtering capacity of the filter screen is reduced to the maximum value of the load of the filter screen. The use is very convenient.
