Description

Technical Field

[0001] The utility model relates to the technical field of fly ash storage, in particular to a bagged incineration fly ash collection, storage and transportation device. Background Art

[0002] Waste incineration fly ash is a waste product generated by processes such as waste incineration, sludge incineration, and hazardous waste incineration. Fly ash is in a fine powder form and contains a variety of pollutants, including heavy metals, dioxins, and salts. Improper collection and storage can pollute the surrounding environment. After being transported in bags, fly ash often needs to be centrally stored, typically in tank-shaped silos. The collection and storage of bagged fly ash inevitably generates a large amount of dust, which not only affects the on-site environment but also the health of on-site operators, while also reducing operational efficiency.

[0003] Therefore, it is of great practical significance to develop a bagged incineration fly ash collection, storage and transportation device with high operating efficiency and low dust generation during operation. Utility Model Content

[0004] Due to the above-mentioned defects in the existing technology, the utility model provides a bagged incineration fly ash collection, storage and transportation device with high operating efficiency and low dust generation during operation, so as to solve the problems of low operating efficiency and large dust generation of the existing bagged incineration fly ash collection, storage and transportation device.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A bagged incineration fly ash collection, storage and transportation device, comprising a collection bin, a screw conveyor, a pipe chain conveyor, a silo, a dust collection hood, a dust collection air duct, a dust collector and a fan;

[0007] A bag unpacker is installed on the top of the collecting bin, the outlet of the collecting bin is connected to the screw conveyor, the discharge end of the screw conveyor is connected to the feed end of the tube chain conveyor, and the discharge end of the tube chain conveyor is connected to the top of the bin;

[0008] A dust collecting hood covering the upper portion of the collecting silo is installed above the collecting silo. The dust collecting hood is connected to the dust collector through a dust collecting air duct, and the dust collector is connected to the fan away from the end of the dust collecting air duct.

[0009] The bagged incineration fly ash collection, storage and transportation device of the utility model has a reasonable structural design. A bag unpacker is installed on the top of the collecting silo to unpack the ton bags. The incineration fly ash in the ton bags is transported to the silo through a screw conveyor and a pipe chain conveyor. The degree of automation is high and the operation efficiency is high. The dust collection hood, dust collection air duct, dust collector and fan can effectively reduce the amount of dust overflow during operation (the amount of dust generated during operation), and the utility model has great application prospects.

[0010] As the preferred technical solution:

[0011] In the bagged incineration fly ash collection, storage and transportation device as described above, high-level alarms and low-level alarms are installed at different heights in the silo. The high-level alarm and low-level alarm can indicate the amount of material in the silo, thereby avoiding excessive or insufficient material in the silo.

[0012] In the bagged incineration fly ash collection, storage and transportation device as described above, a dust collecting hole is opened on the top of the silo, and a dust collecting branch pipe connected to the dust collecting air duct is installed at the dust collecting hole, which can absorb the dust in the silo when unloading, thereby minimizing the amount of dust overflow during operation.

[0013] In the bagged incineration fly ash collection, storage and transportation device as described above, there are multiple silos, and the tube chain conveyor is connected to the tops of multiple silos at the same time.

[0014] In the bagged incineration fly ash collection, storage and transportation device as described above, the outlet of the collection bin is equipped with a collection bin discharge valve for controlling the opening and closing of the outlet.

[0015] The bagged incineration fly ash collection, storage and transportation device as described above also includes a steel frame track and a transportation device;

[0016] The steel frame track is arranged beside the aggregate bin, and a conveying device is installed on the steel frame track for transporting, fixing, and releasing bagged incineration fly ash along the steel frame track. The steel frame track and the conveying device can cyclically and quickly feed the aggregate bin, thereby improving the operation efficiency.

[0017] In the bagged incineration fly ash collection, storage, and conveying device described above, the collection bin, screw conveyor, pipe chain conveyor, and silo are all arranged within a semi-sunken foundation pit. This allows for dust to escape at a relatively low location and settle more quickly, thus minimizing the risk of dust pollution.

[0018] In the bagged incineration fly ash collection, storage and transportation device as described above, a discharge port is provided at the bottom of the silo and a silo discharge valve for controlling the opening and closing of the discharge port is installed at the discharge port.

[0019] The steps for using the bagged incineration fly ash collection, storage and transportation device are as follows:

[0020] Bagged fly ash is transported by car to the unloading warehouse. The device adopts a semi-sunken design, which can easily complete the unloading of bagged fly ash. The bagged fly ash is lifted to the aggregate silo via the steel frame track and conveying device. A bag-breaking cone is set on the top of the aggregate silo, and dust collection hoods are set around the aggregate silo. The dust collection hood is connected to the dust collector through the air duct. At the same time, the dust collection air duct is connected to the storage silo, which effectively controls the leakage of fly ash during the unloading process. The fly ash in the aggregate silo is sent by the screw conveyor to the pipe chain conveyor and then to different silos. The silo is equipped with high and low material level alarms.

[0021] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0022] Compared with the prior art, the above utility model has the following advantages or beneficial effects:
