However, during the prefabrication of angle steel tower components, due to the cutting and welding processes, burrs, unevenness, uneven welds and other problems will occur on the surface of the angle steel tower components. These positions need to be polished to ensure the flatness of the outer wall of the angle steel tower.

[0087] Embodiment 6:

[0088] like Figure 4-7 As shown, on the basis of the above-mentioned embodiment 5, an air guide plate 31 is connected to the bottom end of the air supply pipe 24, an air distributor cylinder 32 is connected to the bottom end of the air guide plate 31, a plurality of air distributor plates 33 are evenly connected to the outer wall of the air distributor cylinder 32 along the circumferential direction, a plurality of side blowing holes 34 are arranged on the air distributor plate 33, the air supply pipe 24, the air guide plate 31, the air distributor cylinder 32, the air distributor plate 33 and the side blowing holes 34 are connected; the grinding motor 13 is connected to the bottom end of the air distributor cylinder 32; the outer wall of the air distributor plate 33 is arranged as an inclined surface, the size of the bottom end of the air distributor plate 33 is smaller than the size of the top end of the air distributor plate 33, and the outlet of the side blowing hole 34 is inclined downward.

[0089] The working principle and beneficial effects of the above technical solution are:

[0090] When the air pipe 24 rotates, the air guide plate 31 is driven to rotate.

[0091] Through the above structural design, the air distributor 32 is integrated above the grinding head 11, so that the blowing airflow can be close to the position of the grinding head 11.

[0096] Embodiment 8:

[0097] like Figure 8 , 9 As shown, based on the above-mentioned embodiment 6, a cooling unit is surrounded and arranged on the gas distribution cylinder 32, and the cooling unit includes:

[0098] A cooling cover 41, which is connected to the bottom end of the air guide plate 31 and arranged outside the air distributor 32. A through groove 42 is provided on the side wall of the cooling cover 41, and the through groove 42 corresponds to the position of the air distributor plate 33;

[0099] Cold storage cylinders 43, multiple cold storage cylinders 43 are obliquely arranged at the lower part of the cooling cover 41 and located between adjacent air distribution plates 33, and the cold storage cylinders 43 are connected to the cooling equipment;

[0100] An upper air inlet pipe 44, the upper air inlet pipe 44 is connected to the top of the cooling cover 41, the top of the upper air inlet pipe 44 is communicated with the cavity of the air guide plate 31, and the first air outlet of the upper air inlet pipe 44 is communicated with the inner cavity of the air distributor 32;

[0101] The lower air inlet pipe 45, the top end of the lower air inlet pipe 45 is connected to the second air outlet of the upper air inlet pipe 44, the bottom end of the lower air inlet pipe 45 extends to the bottom end of the air dividing cylinder 32, and is connected to the lower blowing hole at the bottom end of the air dividing cylinder 32, the lower blowing hole is arranged on the outside of the grinding motor 13, and a spiral section 46 is arranged at a position of the lower air inlet pipe 45 near the cold storage cylinder 43.

[0102] The working principle and beneficial effects of the above technical solution are:

[0103] The airflow in the air distributor plate 33 enters the air distributor cylinder 32 through the first air outlet of the upper air inlet pipe 44, and then flows out through the side blowing holes 34 on the air distributor plate 33. When the airflow flows out, it contacts the cold storage cylinders 43 on both sides and performs heat exchange, so that the temperature of the outflowing airflow is reduced. The low-temperature airflow flows out through the through grooves 42 on the cooling cover 41. The through grooves 42 are arranged corresponding to the air distributor plate 33 and will not block the outflow of the low-temperature airflow; the low-temperature airflow flows downward to the grinding position, quickly reducing the surface temperature of the grinding part of the angle steel tower component, and reducing the influence of high temperature on the grinding accuracy of the angle steel tower component. The airflow enters the lower air inlet pipe 45 through the second air outlet of the upper air inlet pipe 44. When the airflow passes through the spiral section 46, the flow rate slows down, and it fully contacts the cold storage cylinder 43, so that the temperature in the lower air inlet pipe 45 is reduced. The low-temperature airflow flows downward through the lower blowing holes, and at the same time, it sprays and cools the angle steel tower component and the grinding motor 13 directly below, expanding the spray range of the angle steel tower component.

[0104] Embodiment 9:

[0105] like Figure 8 , 9 As shown, based on the above-mentioned embodiment 8, the cooling unit further includes:

[0106] The adsorption plate 47 is connected between the bottom end of the upper air inlet pipe 44 and the air distributor 32;

[0107] The water collecting bin 48 is disposed at the bottom end of the gas distribution cylinder 32 .

[0108] The working principle and beneficial effects of the above technical solution are:

[0109] Since the temperature of the cold storage cylinder 43 is relatively low, the surface temperature of the air separator 32 is relatively low. After the gas in the environment enters the air separator 32, it is easy to produce water droplets when it contacts the low-temperature air separator 32. An adsorption plate 47 is set at the top of the air separator 32. After the airflow enters the air separator 32, the adsorption plate 47 absorbs the water vapor in the airflow, so that the humidity of the airflow is reduced and the possibility of condensation of water droplets is reduced; at the same time, a water collection bin 48 is set at the bottom of the air separator 32. The water droplets generated by the contact between the airflow and the low-temperature air separator 32 flow into the water collection bin 48 through the inclined surface of the air separator plate 33. When the airflow flows through the inclined injection hole 3, it is difficult for the water droplets to flow out due to the surface tension. Through the above-mentioned structural design, the dehumidification of the injection airflow is effectively achieved, so that the water droplets condensed during the cooling process are adsorbed or collected, the moisture carried in the airflow is reduced, and the moisture is prevented from contacting the angle steel tower components during the injection process, the possibility of corrosion on the polished surface of the angle steel tower components is reduced, and the quality of the polishing of the outer wall of the angle steel tower components is improved.
