Description

Vibrating screen

Technical field

The utility model is related to aluminium slag ball production equipment technology more particularly to a kind of vibrating screens.

Background technology

High calcium aluminium slag ball has effects that deoxidation and synthesis refining agent, and when just producing steel, input can be used as deoxidier and remove Free oxygen in steel, after slagging absorption it is strong to be mingled with ability, steel inclusion, cleaning molten steel can be absorbed, rapid slagging is covered in liquid Face prevents molten steel from absorbing gas to completely cut off air.

After high calcium aluminium slag ball is oven-dried in dryer, wherein being also contaminated with the powder that part fails balling-up, need to use Vibrating screen detaches finished product aluminium slag ball with the powder for failing balling-up, and the vibrating screen of the prior art includes hopper, on the outer wall of hopper It is connected with vibrating motor, is connected by multiple springs between hopper and rack, hopper is equipped with for pouring into finished product and powder mixing Mixture feed inlet, hopper is equipped with far from feed inlet one end for be discharged the meal outlet of the powder screened out, feed inlet and Hopper inner wall between meal outlet is equipped with the sieve for sieving product and powder, and hopper is between feed inlet and sieve It is provided with the ball mouth for the finished product screened out to be discharged on side wall, collecting tank is equipped with below meal outlet.

Disadvantage is that when unattended, if after the powder in collecting tank is filled, powder still can going out from hopper Powder mouth is discharged so that powder is overflowed from collecting tank, causes the wasting of resources, and the powder of spilling also needs to staff and carries out clearly It sweeps, indirectly increases the amount of labour of staff.

Utility model content

The purpose of this utility model is to provide a kind of vibrating screens that can collect powder automatically, have and are collected when in collecting tank Powder when reaching default maximum weight, can no longer to arrange into collecting tank from the powder in hopper, powder does not overflow The advantages of collecting tank.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of vibrating screen, including rack and hopper, the hopper is equipped with feed inlet, sieve, meal outlet and ball mouth, described The collection device for collecting the powder screened out is connected at the meal outlet of hopper, the collection device includes for controlling powder Expect the valve member of discharging, for the control assembly of control valve component and for collecting the powder being discharged from valve member Collection assembly, the collection assembly is connected to one end of the meal outlet far from hopper on valve member by control assembly, described Control assembly includes changing with the weight change for the powder collected in collection assembly, connecting collection assembly and valve member Telescoping mechanism and valve member can be driven to open or close with the variation of telescoping mechanism retracted position, connect collection assembly with The toggle of valve member, and when the powder collected in collection assembly reaches default maximum weight or do not collect powder When, the stroke of telescoping mechanism can just make toggle driving valve member completely close or open.

Implement above-mentioned technical proposal, when not collecting powder in collection assembly, telescoping mechanism is in non-telescope amount state, not Toggle rotation is driven, valve member is opened completely, as the powder collected in collection assembly gradually increases, telescopic machine Structure gradually extends under the effect of gravity, while gradually driving toggle operating, and can open control valve component simultaneously Right, when the powder of the collection in collection assembly reaches default maximum weight, telescoping mechanism drives crank connecting link control valve Component completely closes.With when the powder collected in collecting tank reaches default maximum weight, can make from the powder in hopper The advantages of material is no longer arranged into collecting tank, and powder does not overflow collecting tank.

Further, the valve member includes perforation setting at the meal outlet for being sealedly connected on hopper, for passing through powder Valve body and for stop powder by, be rotatably connected on valve interior wall can be along the valve plate of the perforation direction overturning of valve body, institute Valve plate is stated to connect with toggle.
