Abstract
The utility model relates to a pneumatic vibration arch breaking device for powdery feed bins, which is suitable for getting rid of the phenomenon of the overhead arch action of the powdery feed bins and particularly feedstuff bins during discharging and the phenomenon of residual power adhesion on the inner walls of the powdery feed bins. The device is formed by connecting a top cover for a gas supply joint, a shell (cylinder) body, a piston, a chassis and a cabin body, wherein the top part of the piston and the chassis are provided with exhaust holes communicated with the atmosphere. When an external gas source supplies gas into the shell (cylinder) body through an electromagnetic valve, the piston travels downwards to impact and vibrate the powdery feed bin to avoid the phenomena of overhead arch action and residual feed adhesion. When gas supply is stopped, under the action of a return spring, the piston quickly travels upwards to reset. According to requirements, the utility model can automatically and continuously work, and then, the feed bins can not suffer the phenomenon of overhead arch action, or the phenomenon of overhead arch action can be quickly gotten rid of.
Description
The utility model relates to a kind of filler bin usefulness, and particularly feed bin shakes arch breaking apparatus with air pressure, makes somebody a mere figurehead the removing of adhering to remaining powder with filler bin cone inwall of abolishing of arch camber when being suitable for the discharging of powdery feed bin.
During powdery feed bin (as feed bin, flour storehouse, bulk water hopper dredger) discharging, easily form the built on stilts and inwall of arcuation on conical discharge port top and adhere to remaining powder phenomenon.Eliminate above-mentioned phenomenon, existing technology adopts the people to knock the technology of vibrations metal powder feed bin, electric and magnetic oscillation filler bin more, and Shenyang gas big gun factory produces the gas gun device that is used for cement silo, also exists the single and dust of impact direction and fills the air seriously contaminated environment.These technical measures all exist shaking force little, or impact, the vibrations orientation is limited to the filler bin part, maybe can not realize automatically, broken arch continuously, facts have proved that to abolish the effect of adhering to remaining powder phenomenon in built on stilts arch camber of powder and the storehouse bad.
The purpose of this utility model is to provide a kind of brisance strong, shaking force can involve the whole conical section of metal powder feed bin and rapidly, effectively abolish the built on stilts arch camber of powder and the filler bin inwall adheres to remaining powder phenomenon, and energy is automatic, continuous working, makes the normal discharging of filler bin.
Task of the present utility model is finished by following approach.In shell (cylinder) body of filler bin with pneumatic Arch-Breaking Device piston is arranged, when piston is subjected to external bleed pressure effect and along the impact pad of shell (cylinder) the body descending impact shell of inwall (cylinder) body inner bottom part, this impulsive force shakes in the storehouse by chassis, the warehouse connecting panel that is connected with impact pad that powder can not form or abolish rapidly built on stilts arch camber and the feed bin inwall adheres to remaining powder phenomenon, makes the normal discharging of feed bin.Because the piston head in shell (cylinder) body has an aperture and communicates with atmosphere by the deflation hole on the chassis, can impact to drain very soon at descent of piston and act on air pressure on the piston, and piston spill inner chamber has pull back spring, makes the up rapidly position that is returned to before impacting of piston under the effect of pull back spring.Because filler bin is by electric apparatus control apparatus, electromagnetic valve air feed and interrupts air feed with the external source of the gas of moving Arch-Breaking Device, and can adjust confession arbitrarily, stop the supple of gas or steam the time according to broken arch needs, powder be maked somebody a mere figurehead arch camber and removing feed bin inwall adheres to remaining powder phenomenon so can realize abolishing automatically, continuously.
The utility model is compared with the broken arch technology of existing feed bin, it is characterized in that adopting the pneumaticpiston impact structure, its operation pressure is between 0.4-0.8MPa, impulsive force can reach more than the double centner, the whole conical section of metal powder feed bin is given a shock, abolish built on stilts arch camber of powder and filler bin inwall rapidly and adhere to remaining powder phenomenon, and the aperture of piston head communicates with atmosphere, this just can guarantee piston rapid exhaust return after descending impact finishes, thereby guarantees the performance of its continuous working.
Concrete structure of the present utility model is described in detail from the following examples and accompanying drawing thereof.
Fig. 1 is a following longitudinal sectional view of the present utility model
With reference to Fig. 1, top cover (2) is tightened up a screw and is connected with air connector (1), be used for joining with external electromagnetic valve, source of the gas, top cover (2) is threaded with shell (cylinder) body (3), and there is jam nut (4) that it is fastened on shell (cylinder) body (3), shell (cylinder) body (3) lower end and chassis (5) welding, chassis (5) is connected with warehouse connecting panel (7) with 4 bolts (6), warehouse connecting panel (7) is welded on the outer wall of metal powder feed bin cone portion, rapidly the descending impact endurance test shock of piston (8) is passed to whole metal powder feed bin cone.Piston (8) is arranged in shell (cylinder) body (3), be used for bearing the now capable percussion action of external gas compacting, there is a plenum chamber (14) to hold external air pressure between piston (8) and top cover (2), plenum chamber (14) also communicates with atmosphere, piston (8) can slide up and down in shell (cylinder) body (3), its stroke is 40mm, piston (8) is very little through the lapped finish gap with shell (cylinder) body (3) inwall, can only hold the existence of lubricating oil, the outside face of piston (8) and shell (cylinder) body (3) inwall all are to handle through hardness, piston (8) inside is a re-entrant cavity (15), have a diameter at piston (8) top less than 2 millimeters deflation hole (9), having 2 or several deflation holes (13) communicates with atmosphere, be used for getting rid of the air pressure behind the impact endurance test shock, pull back spring (10) is housed in the cavity (15), can make post-decompression piston (8) go up horizontal reset rapidly, the impact pad (11) of shell (cylinder) body (3) inner bottom part is fixed on the chassis (5) with bolt (12), be used for bearing the impact of piston (8), and by chassis (5), warehouse connecting panel (7) is passed to the powder warehouse with impulsive force, cause the vibrations of the whole cone portion of filler bin, built on stilts arch camber of powder and filler bin inwall are adhered to deposit the powder phenomenon and abolish rapidly.The diameter of chassis upper air-vent (13) is greater than piston head deflation hole (9), be beneficial to rapid exhaust, the diameter dimension of piston head deflation hole (9) is less than 2 millimeters, open the moment (0.3 second) of air feed when external electromagnetic valve, have only hoot air pressure to discharge in the hole thus, a large amount of gases can make piston (8) produce enough impulsive forces (more than the double centner); When external electromagnetic valve disconnection stops air feed, air pressure behind the generation impact endurance test shock can pass through deflation hole (9) rapidly, discharge (13), shell (cylinder) body internal gas pressure is equated with ambient pressure, piston (8) is gone up horizontal reset rapidly under the effect of spring (10), to carry out the descending impact of pressurized next time.Twice descending attack time that piston (8) is adjacent can be adjusted to 12 seconds by 2.5 seconds according to the discharging situation of filler bin or the longer time by the control of external connection electrical apparatus control setup.
