[0002] At present, the blade length of wind turbines ranges between 40 and 55 meters. They are usually made of fiberglass or carbon fiber materials, combined with resin, in a special mold. During the manufacturing process of the blades, in order to ensure the proper curing of the resin, it is necessary to maintain an environmental temperature of at least 30°C and keep the environment clean. This requires that the blade manufacturing workshop has good heat preservation and sealing characteristics. However, the curing agent used in the resin curing process usually contains amine compounds that are toxic, have a pungent odor, and are volatile.

[0032] Combined with Figures 1-5As shown in the figure, an air dust removal device for the production of wind turbine blades provided by an embodiment of the present disclosure includes a housing 1. The housing 1 is provided with an air inlet 11, and includes a purification chamber 12 and a gas collection chamber 13 that are connected and communicated. The air inlet 11 is connected and communicated with the purification chamber 12 through an air inlet channel 111. The purification chamber 12 is provided with a plurality of purification cylinders 121, and a ventilation opening 122 is provided at the top. The gas collection chamber 13 is provided with a gas collection area 131 and a gas storage area 132 that are connected and communicated. The gas collection area 131 is provided with a gas collection fan 133, and the gas storage area 132 is provided with an air outlet 134. A dust cleaning component 14 is provided outside the housing 1. The dust cleaning component 14 is provided with a jet port 141. An air ventilation pipe 142 is provided above the ventilation opening 122. One end of the air ventilation pipe 142 penetrates through the housing 1 and extends outside the housing 1 and is arranged opposite to the jet port 141. The air ventilation pipe 142 is provided with a plurality of sub-jet ports 143, and the sub-jet ports 143 are arranged opposite to the ventilation opening 122.
[0033] Using the air dust removal device for the production of wind turbine blades provided by the embodiment of the present disclosure, during the production process of wind turbine blades, glass fiber dust will be generated in the production environment. The air flow to be treated in the production environment enters the purification chamber 12 from the air inlet 11 through the air inlet channel 111, and is purified from the outside to the inside through the purification cylinder 121. The purified air flow passes out from the ventilation opening 122 at the top, and enters the gas storage area 132 of the gas collection chamber 13 under the suction of the gas collection fan 133, and then is discharged outside the device from the air outlet 134, completing the purification process, purifying the production environment, and avoiding affecting the physical health of the staff. After a long purification process, there may be residues of dust and ash on the purification cylinder 121. By setting the dust cleaning component 14, the dust cleaning component 14 sprays air flow through the jet port 141, enters the purification chamber 12 through the air ventilation pipe 142, and sprays towards the ventilation opening through a plurality of sub-jet ports 143 to clean the dust and residues on the purification cylinder 121, completing the cleaning process and improving the subsequent purification efficiency.
[0034] On the basis of the above technical solution, as Figure 1 shown, the dust cleaning component 14 includes an air bag 144 and a pulse valve 145. The air bag 144 is arranged on the outer side wall of the housing 1. The number of pulse valves 145 is multiple, and the multiple pulse valves 145 are connected and communicated with the air bag 144. The jet port 141 is arranged on the side of the pulse valve 145 facing the housing 1.
[0035] Optionally, as Figures 2-4 shown, the purification cylinder 121 is axially provided with a through purification channel 123, and the purification channel 123 extends along the height direction of the housing 1.
[0036] Specifically, as Figure 3 and Figure 4As shown, the ventilation duct 142 is provided with a plurality of sub - ducts. One ends of the plurality of sub - ducts are connected to the ventilation duct 142, and the other ends are arranged towards the purification channel 123. A plurality of sub - jet nozzles 143 are arranged at the other ends of the sub - ducts. During the cleaning process of the purification cylinder 121, the gas in the air bag 144 is sprayed into the ventilation duct 142 from the jet nozzle 141 of the pulse valve 145. Then the air flow is split into a plurality of sub - ducts and ejected from the sub - jet nozzles 143 into the purification channel 123 of the corresponding purification cylinder 121. The air flow has a certain jet force, which can impact and drop the residual dust and residues during the purification process of the purification cylinder 121, playing a role in cleaning the purification cylinder 121 and facilitating subsequent purification.
[0037] Optionally, as Figure 3 and Figure 5 shown, the plurality of purification cylinders 121 are evenly distributed along the length and width directions of the housing 1.

The connecting portion cooperates with the connecting and cooperating portion so that the fixing plate 15 is fixed to the plurality of purification cylinders 121, and the fixing plate 15 is fixedly connected to the housing 1 in the circumferential direction. Therefore, the plurality of purification cylinders 121 are fixed relative to the housing 1 through the setting of the fixing plate 15. Specifically, the connecting portion can be a screw hole, and the connecting and cooperating portion can be a mating hole. Screws pass through the mating hole and the screw hole in sequence to fix the plurality of purification cylinders 121 to the fixing plate 15.
[0040] Based on the above - mentioned technical solution, the gas - collecting fan 133 includes an inlet and an outlet. The inlet is arranged towards the purification chamber 12, and the outlet is arranged towards the gas storage area 132.
[0041] Optionally, the housing 1 is provided with heat - dissipation holes, which are arranged opposite to the gas - collecting fan 133 for dissipating heat of the gas - collecting fan 133, avoiding the temperature of the gas - collecting fan 133 being too high due to long - term operation and affecting the subsequent work efficiency.
[0042] Based on the above - mentioned technical solution, as Figure 1As shown, an air outlet pipe 16 is provided on the outer side of the housing 1 corresponding to the air storage area 132. One end of the air outlet pipe 16 is arranged opposite to the air outlet 134, and the other end extends obliquely downward in a direction away from the air outlet 134.

[0045] Based on the above technical solution, as Figure 5 shown, the dust collection chamber 17 is provided with an auxiliary dust collection structure 171. One side of the auxiliary dust collection structure 171 is connected to the housing 1, and the other side slopes downward in a direction away from the housing 1 and is connected to the dust collection chamber 17, so that the fallen dust can slide down from the auxiliary dust collection structure 171 into the dust collection chamber 17.
[0046] Optionally, as Figure 5 shown, a perspective window 191 is provided on the side of the dust collection chamber 17, facilitating the observation of the dust collection situation in the dust collection chamber 17. The number of dust collection chambers 17 can be multiple, and the number of perspective windows 191 can also be multiple.

The fire extinguishing ball 18 includes a water storage part 181 and a water spraying part 182. The water storage part 181 is communicated with the water spraying part 182, and the water spraying part 182 faces the purification cylinder 121.
[0048] Specifically, as a fire extinguishing device, the air flow that enters the purification chamber 12 through the air inlet 11 through the air inlet pipe may have a situation accompanied by sparks. At this time, the water storage part 181 of the fire extinguishing ball 18 provides water to the water spraying part 182, and the water spraying part 182 sprays water into the purification chamber 12 to extinguish the fire and avoid potential safety hazards.
[0049] Based on the above technical solutions, as Figure 2 and Figure 3 shown, a reserved air inlet 19 is provided on the side of the housing 1 adjacent to the air inlet 11, for communicating with devices arranged in different directions.
