The other end of connecting axle 9 passes the lateral wall of electrical cabinet body 1 to be connected with handle 25 respectively, be provided with stopper 26 on the lateral wall of electrical cabinet body 1, stopper 26 is located connecting axle 9 under, and be provided with the screw hole with fastening bolt 27 looks adaptation on stopper 26 and the connecting axle 9 respectively, conveniently rotate connecting axle 9 through the handle 25 that sets up, stopper 26 and fastening bolt 27's cooperation is used, and with fix connecting axle 9.

The working method of the electric appliance cabinet comprises the following steps:

s1, starting a turbo fan 23 and a motor in a driving mechanism, enabling outside air to enter the turnover dust removal mechanism through the air inlet cover 7 along the air inlet pipe 8 under the action of the turbo fan 23, and then filtering the outside air through the first filter screen 12 and the second filter screen 13 to remove impurities of large particles;

s2, a motor in the driving mechanism drives a driving belt pulley to rotate, the driving belt pulley drives a driven belt pulley 18 to rotate through a belt 19, the driven belt pulley 18 which rotates drives a bearing seat to rotate, so that the filter element 14 on the bearing seat rotates, and therefore gas filtered by the first filter screen 12 and the second filter screen 13 is filtered through three groups of filter elements 14 which rotate continuously and small-particle impurities are removed;

s3, the gas filtered by the filter element 14 sequentially enters the element chamber 3 on the electric appliance cabinet body 1 along the exhaust pipe 33 and the communicating pipe 22;

s4, when workers need to clean the turnover dust removal mechanism regularly, the fastening bolts 27 on the limiting blocks 26 are detached, then the handle 25 is rotated to drive the connecting shaft 9 to rotate, the connecting shaft 9 drives the side plates 11 and the first filter screen 12 to rotate outwards along the second filter screen 13, large-particle impurities borne on the first filter screen 12 can be cleaned, after cleaning is completed, the connecting shaft 9 is rotated to close the side plates 11 and the through holes in the side wall of the electric appliance cabinet body 1, and then the connecting shaft 9 is fixed through the fastening bolts 27;

s5, when the filter element 14 needs to be cleaned regularly, the worker connects the air pipe 21 with an external air tank, and then opens a valve on the air pipe 21, so that the air in the air tank is blown back to the filter element 14 through the air pipe 21 and the exhaust pipe 33, and then the small particles, impurities and dust on the surface of the filter element 14 can be cleaned.

In the invention, when the device works, the turbo fan 23 and the motor in the driving mechanism are started, under the action of the turbo fan 23, outside air enters the turnover dust removal mechanism through the air inlet cover 7 along the air inlet pipe 8, and then the outside air is filtered by the first filter screen 12 and the second filter screen 13, and impurities of large particles are removed; the overturning dust removal mechanism can effectively filter large-particle impurities contained in the outside air, so as to achieve the effect of preliminary dust removal and purification on the outside air, effectively relieve the working strength of the filter element 14, prolong the service life and working time of the filter element 14, and reduce the times of cleaning the filter element 14;

in addition, the connecting shaft 9 is driven to rotate by the handle 25, the connecting shaft 9 drives the side plate 11 and the first filter screen 12 to rotate outwards along the second filter screen 13, so that the first filter screen 12 bearing large particulate impurities is unfolded and displayed on the outer wall of the electric appliance cabinet body 1, workers can conveniently clean the large particulate impurities on the first filter screen 12, the cleaning of impurity dust in the later dust removal period is greatly improved, and the labor force of the workers is reduced;

a motor in the driving mechanism drives a driving belt pulley to rotate, the driving belt pulley drives a driven belt pulley 18 to rotate through a belt 19, the driven belt pulley 18 which rotates drives a bearing seat to rotate, so that the filter element 14 positioned on the bearing seat rotates, and therefore gas filtered by the first filter screen 12 and the second filter screen 13 is filtered by three groups of filter elements 14 which rotate continuously and small-particle impurities are removed; the gas filtered by the filter element 14 sequentially enters the element chamber 3 on the electric appliance cabinet body 1 along the exhaust pipe 33 and the communicating pipe 22, so that the effect of grading and dedusting the external gas can be achieved, the dust removing effect is good, the dust removal is more thorough, cleaner gas can enter the electric appliance cabinet body 1,

in addition, through being connected trachea 21 with external gas pitcher, then open the valve on the trachea 21 for gas on the gas pitcher carries out the blowback through trachea 21 and blast pipe 33 to filter core 14, can convenient and fast clear up the small particle thing impurity on the filter core 14 surface.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
