Description
Technical field
Technical field of engineering machinery is the utility model is related to, especially a kind of automatic filler bin for changing screen pack.
Background technology
In concrete mixing plant, powder enters filler bin by metering, and aggregate enters aggregate bin by metering.Powder particle size
It is tiny, easily float or reveal during conveying, therefore the structure of filler bin generally use and extraneous opposing seal to prevent
Only powder flies away.
But the charging of filler bin and discharging process can cause pressure in filler bin to change, the change of pressure causes powder
Shape material into and out of mobility change, the metering of powder may be had an impact.In order to ensure that filler bin is feeding and gone out
Pressure is constant during material, and in general solution is that screen pack is set in the nacelle of filler bin to be used as ventilating opening.By
In the characteristic of powder, the screen pack of ventilating opening is very easy to obstruction, can so cause pressure change in filler bin to exceed permissible value
So that powder metering is inaccurate, serious quality accident may be caused.And the screen pack obstruction of ventilating opening is incidental, need
Personnel are wanted to inspect periodically or change, maintenance cost is high, as negligent supervision there may be the risk changed not in time.
Utility model content
The purpose of this utility model be in order to solve the screen pack of filler bin ventilating opening in background technology easily obstruction, it is necessary to
The problem of personnel inspect periodically or changed, realize a kind of filler bin that can change screen pack automatically.
In order to solve problem above, the utility model provides a kind of automatic filler bin for changing screen pack, including powder
Storehouse body, the filler bin body upper part are provided with the ventilating opening of square structure, and the opening edge edge of the ventilating opening, which is provided with, to be adapted
Frame, the right and left of the frame is provided with gap, and upper and lower both sides are provided with neck, by left and right gap and upper in the frame
One layer of screen pack is equipped with the presence of lower bayonet slot, the screen pack side is that web-like is wound on a roller bearing, opposite side connection
In a rotating shaft, the rotating shaft connects dynamical system, and pressure inductor, the dynamical system and institute are provided with the filler bin body
State pressure inductor and be all connected to control unit.Staff is in operation, can set dynamical system according to the size of ventilating opening
The work period of system, when congestion situations occurs in screen pack, the pressure inductor in filler bin will be signaled to control unit,
Control unit starts dynamical system so that axis of rotation, rotating shaft drive screen pack, and dynamical system is unified after the work period terminates, to turn
Axle also stops operating, and the screen pack covered on ventilating opening is updated to new one layer, and old screen pack is wrapped in rotating shaft, realizes
It is automatic to change screen pack, without hand inspection and change, as long as when a roll of screen pack has used, replacing once may continue to work
Make, it is simple and convenient.
Preferably, the roller bearing is externally provided with the protection cap of a cuboid, the protection cap is rotationally connected with the powder
On the body of storehouse.Because the ambient dust of concrete mixing plant is more, protection cap can protect new screen pack not by dust pollution,
Ensure the quality of screen pack.
Preferably, the lower edges of the screen pack are provided with positioning strip, the width of the neck opening is less than positioning strip
Width, the gap upper and lower ends, which are provided with, adapts to the opening of the positioning strip.Positioning strip can guarantee that up and down the two of screen pack
End is fixed in neck, prevents rotating shaft during scrolling screen pack, and the upper and lower ends of screen pack will not be run out of in neck, is ensured
Screen pack covers ventilating opening all the time.
Preferably, it is equipped with wool top in the gap of the frame and neck.Wool top can play certain sealing function, prevent
Outside only powder flies out from space, and there is airing function to a certain extent, even if being blocked on screen pack by certain dust,
Pressure in filler bin will not also change the service life that too much, can extend screen pack.
The utility model is through using proof, effect is preferable, simple and practical.

Embodiment
The automatic filler bin for changing screen pack a kind of to the utility model is described further below in conjunction with the accompanying drawings.
Shown in as shown in Figure 1, Figure 2, the utility model provides a kind of automatic filler bin for changing screen pack, including filler bin
Body 1, the top of filler bin body 1 are provided with the ventilating opening 2 of square structure, and the opening edge edge of the ventilating opening 2, which is provided with, mutually fits
The frame 3 matched somebody with somebody, the right and left of the frame 3 are provided with gap, and upper and lower both sides are provided with neck, and the frame 3 is interior in left and right gap
With one layer of screen pack 4 is equipped with the presence of upper lower bayonet slot, the lower edges of the screen pack 4 are provided with positioning strip, the neck
