Embodiment Construction

[0016] The structure of the present invention is as figure 1 and figure 2 As shown in the figure, there is a shaft-type discharge device for compacted sand storage. The bottom of shaft 1 is equipped with equipment vibrating feeder 2. The equipment vibrating feeder 2 cooperates with discharge port 3, and the surrounding area of ​​discharge port 3 is evenly arranged. A vibrating bar device 4 is arranged, and the vibrating bar device 4 extends into the arching and hardening area 5, and a tape conveyor 7 is arranged below the vibrating feeder 2 of the equipment.

[0017] The vibrating bar device 4 of the present invention includes a fixed shell 18 installed on the base 10, the fixed shell 18 is connected with the hard shaft vibrating bar 12 by the shell connecting plate 13, and a buffer pad is arranged between the fixed shell 18 and the contact surface of the base 10 11. A hard shaft vibrating rod 12 is arranged inside the fixed shell 9, and the hard shaft vibrating rod 12 is in...

Abstract

Provided are a discharge device and a discharge method for vertical shaft type rolling sand storage material. An equipment vibration feeder installed at the bottom of a vertical shaft is matched with a discharge port, vibration rod devices evenly distributed on the periphery of the discharge port are stretched into arch camber hardened areas, and a sealing-tape machine is installed below the equipment vibration feeder. The discharge device and the discharge method for the vertical shaft type rolling sand storage material provide a vibration rod group composed of the vibration rod devices, utilize multipoint additional excitation force, achieve arch breaking and discharge through resultant force with feed equipment, and solve the discharge problems of the vertical shaft type rolling sand storage material. The vibration rod devices stretched into the arch camber hardened areas generate small amplitude and achieve high-frequency vibration. Under the action of the vibration rod devices, internal friction and adhesive force among particles of arch camber hardened rolling sand are reduced, and mobility of the arch camber hardened rolling sand is increased. Under the action of force of gravity, the arch camber hardened rolling sand mutually slides, breaks arch, and is discharged from the discharge port conveniently.

Description

technical field [0001] The invention relates to a discharge device, in particular to a discharge device for shaft-type roller compacted sand storage. The invention also relates to a method for completing discharging by using the discharging device. Background technique [0002] With the development of dam-building technology, the terrain is becoming more and more steep, and the construction site is narrow and steep. The storage of the finished rolled sand during construction adopts shaft storage, which has the characteristics of small footprint, high effective volume, and better adaptability to relevant terrain. However, in the process of storing rolled sand, due to its water content and stone powder content, it is easy to arch, resulting in poor discharge or hardening, which seriously affects normal production and limits the application of shaft storage methods. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide ...
