Bagged cement automatic bag-opening and discharging device for nuclear power station

Abstract

The invention relates to a bagged cement automatic bag-opening and discharging device for a nuclear power station. The bagged cement automatic bag-opening and discharging device for the nuclear power station comprises a sealing box, a conveying mechanism, a controller and a starting button. The bagged cement automatic bag-opening and discharging device for the nuclear power station is characterized by comprising a vertical lifting door, a cement bag recycling door and a cement exit. A cutting knife is fixed on the inner surface of the vertical lifting door, and the vertical lifting door is driven by a dynamic mechanism. An unpowered roller way and a belt conveying machine are respectively arranged inside and outside the vertical lifting door, and a guide rail is arranged on the upper portion of an outer shell. A motor can move on the guide rail through that a steel wire rope drags a bag-grabbing mechanism. A fine dust collecting machine is arranged on the top of the outer shell, signal input ends of the controller are respectively connected with signal output ends of a photoelectric sensor, a limiting switch and the starting button. Output ends of the controller are respectively connected with control ends of the belt conveying machine, the dynamic mechanism and the motor. The bagged cement automatic bag-opening and discharging device for the nuclear power station is simple in structure, low in cost, small in size, reliable in sealing, safe and convenient to use and maintain, and capable of meeting requirements for environmental protection of the nuclear power station.

Description

technical field

[0001] The invention relates to a bag opening and unloading device, in particular to an automatic bag opening and unloading device for bagged cement used in nuclear power plants. Background technique

[0002] During the operation of nuclear power plant waste treatment facilities, a large amount of cement needs to be used to solidify the waste. Manually opening bags and sending the cement to the mixing station is not only labor-intensive, it is easy to cause occupational diseases such as pneumoconiosis, and the dust will be radioactive after being irradiated. Serious polluted environment. The existing mechanical bag opening device has a large volume, a large floor space, and high cost, and it cannot completely separate the dry cement material and the cement bag when it works, and some crushed cement bags will be mixed into the dry cement material, causing the cement to be polluted. Chinese patent No. 200710134438.9 discloses a device for automatically opening...
