Abstract
The utility model discloses a discharging device of a silo type roller-compacted sand storage hopper. An equipment vibrating feeder is arranged at the bottom of a silo and matched with a material discharge port, vibrating rod devices are evenly arranged around the material discharge port and stretch into an arch-forming harden region, and a belt conveyor is arranged below the equipment vibrating feeder. According to the silo type roller-compacted sand storage hopper, a vibrating rod group composed of the vibrating rod devices is arranged, excitation force is applied on multiple points, and the vibrating rod group is matched with the equipment vibrating feeder to break arch blocks and discharge roller-compacted sand, and therefore the material discharging problem of the silo type roller-compacted sand storage hopper is solved. Since the vibrating rod devices stretch into the arch-forming harden region, small-amplitude high-efficiency vibration is generated, under the action of the vibration, internal friction force and adhesive force among particles inside arch-shaped harden roller-compacted sand plates decrease, liquidity is increased, the particles slide among each other under the action of gravity, and therefore the arch-shaped harden roller-compacted sand plates break up, and the roller-compacted sand can be discharged from the material discharge port conveniently.
Description
Technical field
The utility model relates to a kind of drawing mechanism, and particularly a kind of vertical shaft type rolls the drawing mechanism of sand storing.
Background technology
Along with the development of dam construction technique, physical features is more and more dangerously steep, and the workyard is narrow steep.Finished product in construction rolls the storage of sand and adopts the vertical shaft storing, has characteristics such as taking up an area little, effective volume height, the relevant physical features of better adaptation.But roll in the process of sand in storage, because its aqueous ingredients, content of stone powder, arch camber causes blowing smooth or harden can't blowing easily, has a strong impact on normal production, has limited the application of the storing mode of vertical shaft.
Summary of the invention
Technical problem to be solved in the utility model provides the drawing mechanism that a kind of vertical shaft type rolls the sand storing, solution rolls in the process of sand in storage, because its aqueous ingredients, content of stone powder, easily arch camber cause blowing smooth or harden can't blowing problem.
The purpose of this utility model is achieved in that a kind of vertical shaft type rolls the drawing mechanism of sand storing, silo bottom is provided with the vibration equipment feeder, the vibration equipment feeder matches with discharge port, be evenly arranged the vibrating arm device around the discharge port, the vibrating arm device extend into the arch camber district of hardening, and is provided with sealing-tape machine below the vibration equipment feeder.
Described vibrating arm device comprises the fixed housing that is installed on the pedestal, fixed housing is connected with hard shaft vibration bar by the shell gusset piece, be provided with cushion rubber between fixed housing and the pedestal contact surface, be provided with hard shaft vibration bar in the fixed housing, hard shaft vibration bar is installed on the oscillatory system supporter, and hard shaft vibration bar is connected with motor.
On the hard shaft vibration bar addition rod is installed.
Be provided with the oscillatory system cushion rubber between hard shaft vibration bar and the oscillatory system supporter.
The vertical shaft type that the utility model provides rolls the drawing mechanism of sand storing, and a vibrating arm group who is made of the vibrating arm device is provided, and adopts the additional disturbance force of multiple spot, with the feeding device broken arch discharging of making a concerted effort, solves the discharging problem that vertical shaft type rolls the sand storing.The vibrating arm device stretches into the arch camber district of hardening, the little amplitude of generation, high-frequency vibration, arch camber is hardened roll sand under its effect of vibration, internal friction, binding force between the particle reduce, and flowing power increases, mutually slide under action of gravitation, broken arch is convenient to draw off from discharge port.Addition rod can enlarge oscillating region.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of vibrating arm device.
The specific embodiment
Structure of the present utility model as depicted in figs. 1 and 2, a kind of vertical shaft type rolls the drawing mechanism of sand storing, vertical shaft 1 bottom is provided with vibration equipment feeder 2, vibration equipment feeder 2 matches with discharge port 3, be evenly arranged vibrating arm device 4 around the discharge port 3, vibrating arm device 4 extend into arch camber harden the district 5, below vibration equipment feeder 2, be provided with sealing-tape machine 7.
Vibrating arm device 4 of the present utility model comprises the fixed housing 18 that is installed on the pedestal 10, fixed housing 18 is connected with hard shaft vibration bar 12 by shell gusset piece 13, be provided with cushion rubber 11 between fixed housing 18 and pedestal 10 contact surfaces, be provided with hard shaft vibration bar 12 in the fixed housing 9, hard shaft vibration bar 12 is installed on the oscillatory system supporter 16, and hard shaft vibration bar 12 is connected with motor 14.
On the hard shaft vibration bar 12 addition rod 15 is installed.
Be provided with oscillatory system cushion rubber 17 between hard shaft vibration bar 12 and the oscillatory system supporter 16.
Principle of work of the present utility model is as follows:
Conventional discharging method is to adopt vibrating feeder or arc door blowing.Roll sand arch camber vault position generally at discharge port upper limb 1m ~ 2m place, owing to roll sand powder content height, add the impact of aqueous ingredients, internal friction and binding force between the internal particle are large.Vibration is not enough to be applied to this part through the disturbance force of materials device itself, and after the following material vibrating discharging, an interim arch has been formed at top, hinder follow-up material to bottom discharge.Guarantee normal feed, will destroy this arch.
The utility model provides a vibrating arm group who is made of a plurality of vibrating arm devices 4, adopts the additional disturbance force of multiple spot, with the feeding device broken arch discharging of making a concerted effort, solves the discharging problem that vertical shaft type rolls the sand storing.
Under silo bottom feeding device vibrating feeder operation prerequisite, open successively behind the time-delay 1min and be arranged in discharge port vibrating arm device 4 all around, behind vibrating arm device 4 work 10S ~ 20S, again by vibrating feeder 2 separately normal feeds.Vibrating arm device 4 stretches into the arch camber district of hardening, the little amplitude that produces, the high-frequency vibration is hardened arch camber and is rolled sand under its effect of vibration, and internal friction, binding force between the particle reduce, flowing power increases, mutually slide under action of gravitation, broken arch is drawn off by discharge port 2, through vibrating feeder feed sealing-tape machine 7 in the transportation hole, send through sealing-tape machine 8 again.
Vibrating arm device 4 is arranged will avoid discharge zone, is arranged on dead band 19 or faces discharge zone 9, in order to avoid during normal discharging, material is to the abrasion of the fixed housing of vibrating arm.Addition rod 15 can enlarge oscillating region.
