Description
Technical Field
[0001] The utility model relates to the technical field of shot blasting machines, in particular to a wind speed regulating device for a separator of a shot blasting machine. Background Art
[0002] At present, the shot blasting machines on the market use the method of ejecting projectiles to remove rust from steel, but there are certain defects in the local functions. In the shot blasting machine, there is a device called a shot sand separator. The separator fan draws air through the separator exhaust hole, and uses the principle of gravity air separation to effectively separate the projectiles from the waste materials such as metal oxide scale fragments, broken projectiles, and dust from the shot sand mixture. The lighter fragments, broken projectiles, and dust are blown into the gap between the upper and lower windshields by wind, and then flow out from the waste outlet. The heavier complete projectiles and large-particle waste fall on the isolation screen, and the large-particle waste is screened out from the isolation screen. The complete projectiles pass through the isolation screen mesh and fall into the shot bin for circulation. However, in actual operation, the shot-sand separator often lacks wind power, resulting in a large amount of dust and fine waste not being sucked away by the separator fan into the waste outlet. Instead, they are mixed with the shot and fall on the isolation screen, blocking the isolation screen. Eventually, the shot accumulates on the isolation screen and cannot enter the shot silo in time for circulating rust removal. Human power is required to pick out the waste, which not only reduces work efficiency but also increases labor costs. Utility Model Content

[0025] See also Figures 1 to 7 The utility model provides an embodiment: a wind speed regulating device for a shot blasting machine separator 1, comprising a shot blasting machine separator 1 and a wind speed adjustable component 2, wherein a feed port 3 is arranged at the top of the shot blasting machine separator 1, an air inlet 4 is opened at the front end of the shot blasting machine separator 1, an upper wind shield 5 is fixed at the upper end of the shot blasting machine separator 1, a lower wind shield 6 is fixed at the lower end of the shot blasting machine separator 1, a sieve plate 8 is fixed at the front end of the bottom of the lower wind shield 6, and multiple groups of steel bars 7 with relative positions are inherent on both sides of the wind speed adjustable component 2, and the wind speed adjustable component 2 is fixed to the lower wind shield 6 through the steel bars 7. The shot sand mixture 10 enters the shot blasting machine separator 1 from the feed port 3, and the wind 13 of the fan enters from the air inlet 4 at the front end of the shot blasting machine separator 1. By increasing the height of the lower wind shield 6, the distance between the upper and lower wind shields 6 is shortened, thereby reducing the area of the air outlet, and utilizing the principle of gravity air selection, such as Figure 6 As shown, the wind 13 of the fan enters from the air inlet 4 at the front end of the shot blasting machine separator 1, and the shot-sand mixture 10 enters the shot blasting machine separator 1 from the feed port 3. The waste 11 can be effectively blown to the waste outlet 11 of the shot blasting machine separator 1, and the fine waste 11 is separated from the shot 12. The shot 12 falls after being filtered through the screen, thereby effectively separating a large amount of dust and fine waste 11 from the shot 12, and ensuring the circulation of the shot 12.
[0026] Please continue reading Figure 1 , Figure 2As shown, in one embodiment of the present invention, the feed port 3 is in the shape of an inverted cone. The inverted cone shape allows the waste 11 and the pellets 12 to fall evenly, making it easier to separate the fine waste 11 from the pellets 12.

The first steel plate 21 is fixed to the lower wind shield 6 by the steel bars 7, and the height of the lower wind shield 6 is increased, and the distance between the upper and lower wind shields 6 is shortened, thereby reducing the area of the air outlet. Based on the air volume = wind speed × area, when the power is not variable, that is, the air volume is constant, the wind speed and the area are inversely proportional, and the area is reduced, the wind speed of the air outlet can be increased, and the principle of gravity air selection is used to effectively separate a large amount of dust and fine waste 11 from the projectile 12, so as to ensure the circulation of the projectile 12, and the wind speed can also be adjusted by setting the first steel plates 21 of different sizes.

The second steel plate 22 can be fixed on the first through holes 24 of different heights on the U-shaped fixing groove 23 to adjust the height of the second steel plate 22, thereby adjusting the wind speed.
[0029] Please continue reading Figure 3 As shown, in one embodiment of the utility model, more than three first through holes 24 are provided. The first through holes 24 can be provided with three, four, or five according to specific needs. By locking the second steel plate 22 to the first through holes 24 at different positions, the height of the second steel plate 22 can be adjusted, thereby achieving the adjustment of the wind speed.

The steel bar 7 has a certain elasticity, and the steel bar 7 is provided with a slope of 2° inwardly inclined to fix the wind speed adjustable component 2 firmly on the lower windshield 6.
[0031] Please continue reading Figure 5 , Figure 7 As shown, in one embodiment of the utility model, the lower end of the steel bar 7 facing inward is provided with a chamfer 9. The setting of the chamfer 9 enables the steel bar 7 to be easily connected to the lower wind shield 6 without having to separate the distance between the steel bars 7 fixed on both sides of the wind speed adjustable component 2.
