Embodiment
Fig. 1 ~ 4 are most preferred embodiments of the present utility model, and 1 ~ 4 pair of the utility model is done furtherly below in conjunction with the accompanying drawings It is bright.
A kind of shot pneumatic separation device, including feed bin 1, the finished bin 5 of the bottom of feed bin 1 and waste product storehouse 6 and air channel, feed bin 1 Downside be rotatablely equipped with discharge roller 9, the outer wall of discharge roller 9 is provided with multiple material stock portions, and discharge roller 9 is connected with drive its rotation Power unit, the shot in feed bin 1 enters material stock portion, and falls when material stock portion turns to 9 downside of discharge roller.This shot wind The downside of feed bin 1 of screening device is provided with discharge roller 9, and shot falls with the rotation of discharge roller 9, no matter the number of the shot in feed bin 1 How much is amount, and discharge roller 9 can control shot to fall at a same speed, it is ensured that shot falling speed is stable, so as to be formed Heavy curtain in uniform thickness, makes selection by winnowing more stablize, and can adjust the discharging speed of shot by adjusting the rotating speed of discharge roller 9 Degree, it is easy to use.
Specifically:As shown in Figure 1:Finished bin 5 is arranged on below the discharging opening of feed bin 1, and waste product storehouse 6 is arranged on feed bin 1 On the left of discharging opening, the left and right sides of finished bin 5 is gradually inside taper from top to bottom, and the right side in waste product storehouse 6 is from top to bottom Gradually inclination to the left is filled, and the left side upper end of finished bin 5 is connected with the right side upper end in waste product storehouse 6.
The downside of feed bin 1 is provided with guide plate 4, and guide plate 4 is from top to bottom arranged at intervals with 2 ~ 4 pieces, led in the present embodiment Plate 4 is provided with three pieces, the upside for being arranged on finished bin 5 and waste product storehouse 6 that guide plate 4 can horizontally slip, guide plate 4 is by a left side To right gradually upward skewed, and the angle of guide plate 4 and horizontal plane is 60 ° ± 15 °, and the right side of guide plate 4 is located at feed bin 1 The left side of discharging opening.The downside of feed bin 1 is provided with installing plate, and installing plate is corresponded with guide plate 4, and installing plate and guide plate 4 be arranged in parallel, and guide plate 4 is slidably installed on a mounting board.When shot falls, due to the effect of wind-force, solid shot weight compared with Greatly, what is offset to the left in dropping process is in small distance, can fall into finished bin 5, and the weight of hollow shot is smaller, in dropping process It is cheap in larger distance to the left, so as to can drop down onto on guide plate 4, and it is moved to the left along guide plate 4, so that by guide plate 4 Left end is fallen into waste product storehouse 6.When the position of regulation guide plate 4 in the horizontal direction, under the shot of the right-hand member of guide plate 4 and feed bin 1 The relative position of drop point changes, and needs the displacement of horizontal direction less so that shot is fallen on guide plate 4, and then It has adjusted the hollow rate of the shot fallen into finished bin 5.
Air channel is arranged on the upside of the downside of feed bin 1, finished bin 5 and waste product storehouse 6, and the right-hand member in air channel is air inlet, air channel Left end is air outlet 2.Air-flow plate 3 is rotatablely equipped with the air outlet 2 in air channel, the rotating shaft of air-flow plate 3 is horizontally disposed with, Air-flow plate 3, which is rotated, can change the cross-sectional area of air outlet 2, so as to change intake, the less of intake can cause The change of wind speed, so that the hollow rate for the shot for falling into finished bin 5 is changed, it is easy to adjust.
The air outlet 2 in air channel is connected with settling bin 7, and settling bin 7 has two, and two settling bins 7 are arranged side by side along wind direction, wind The air inlet of settling bin 7 on the right side of the connection of road air outlet 2, the air outlet connection air-suction duct of the settling bin 7 in left side.Wind is along air channel Into after settling bin 7, due to cross-sectional area increase, wind speed slows down, so that the dust being mingled in shot can sink in settling bin 7 Form sediment, set two settling bins 7 to ensure that the sedimentation effect of dust is good.
As shown in Figure 2:Feed bin 1 is cuboid cylinder, and the bottom of the left and right sides of feed bin 1 is gradually inside from top to bottom It is skewed, and form discharging opening in the downside of feed bin 1.Discharge roller 9 is rotatably installed in the discharge outlet of feed bin 1, the right side of feed bin 1 The distance of bottom and the outer wall of discharge roller 9 is less than the diameter of shot, so that shot is fallen by the right side of discharge roller 9, under the left side of feed bin 1 Portion is the baffle plate being engaged with discharge roller 9, and discharge roller 9 rotates in the counterclockwise direction, and the shot in feed bin 1 enters discharge roller 9 In material stock portion, and fallen when material stock portion turns to 9 downside of discharge roller.
The downside of discharge roller 9 is provided with horizontally movable supporting plate(It is not drawn into figure), pass through the right position of supporting plate Regulation, thus it is possible to vary the setting point of shot, so as to adjust the yield rate of the shot fallen into finished bin 5.
As shown in Fig. 3 ~ 4:Discharge roller 9 fills for cylinder, and the outer wall around discharge roller 9 is interval with multiple axial hoppers 901, storing portion is formed, the width of hopper 901 is slightly larger than the diameter of shot.The diameter at the two ends of discharge roller 9 is less than the diameter at middle part, So as to form installation portion 902 at the two ends of discharge roller 9, discharge roller 9 is rotatably installed in the downside of feed bin 1 by installation portion 902.Discharge roller 9 one end is connected with power unit, and power unit is motor, and reductor is provided between motor and discharge roller 9.
The course of work of this shot pneumatic separation device is as follows:Hollow rate as needed first is adjusted to shot pneumatic separation device Pending shot, is then put into feed bin 1 by section, then starts motor, and motor drives discharge roller 9 to rotate, so that Shot in feed bin 1 falls to forming heavy curtain, in shot dropping process, can be deviated to the left under the wind-force effect in air channel, single solid steel What is be deviated to the left in ball dropping process is in small distance, so as to fall into finished bin 5, it is in larger distance that hollow shot is deviated to the left, It can drop down onto on guide plate 4, and enter along guide plate 4 in waste product storehouse 6.When wind in air channel enters settling bin 7, due to passage cross sectional Area increases, and wind speed slows down, and dust can be precipitated in settling bin 7.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model Limitation, any those skilled in the art are changed or are modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of change.But it is every without departing from technical solutions of the utility model content, it is real according to technology of the present utility model Any simple modification, equivalent variations and remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model Protect scope.
