Background
The hazardous waste is a final product of garbage treatment which can not be utilized by people, contains a large amount of heavy metals, dioxin and the like, and is conveyed by a metering and conveying mechanical device of a batching system, enters a stirrer, is added with a curing agent and a stabilizing agent to form a stable whole, so that the heavy metals, the dioxin and the like cannot be separated out, and then enters a landfill site subjected to multilayer anti-seepage treatment for landfill, thereby ensuring that the environment is not polluted.
The hazardous waste is fly ash formed after the waste incineration, and the traditional fly ash is conveyed in a pneumatic conveying mode, namely, dry fly ash is blown into a suspension shape by high-pressure air, conveyed in a closed pipeline of a screw conveyor and conveyed to a weight increasing weighing scale, and then enters a waste hazardous mixer according to the required specific weight. This transport metering system allows for transport of normal, non-moist fly ash. However, the moisture phenomenon is easy to occur for a small batch of fly ash packaged by ton bags, and the traditional conveying and metering mode cannot be used for the wet fly ash packaged by ton bags.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the problem of carry the measurement to caking or moist ton package flying dust can't be handled among the prior art because of the useless curing equipment flying dust of danger carries, provides a useless curing equipment ton bag flying dust of danger and carries measurement system.
The utility model provides a technical scheme that its technical problem adopted is: a hazardous waste curing equipment ton bag fly ash conveying and metering system comprises a bucket elevator, a weightlessness metering scale capable of realizing accumulated feeding, a weighing sensor, a discharge door, a hazardous waste mixing machine and a controller, wherein the weightlessness metering scale is arranged below a discharge port at the top of the bucket elevator, a discharge port of the bucket elevator is hermetically connected with a feed port of the weightlessness metering scale, and the bucket elevator is connected with the controller; the weighing sensor is arranged on the weightless weighing scale and is connected with the controller; a discharge door is arranged at the discharge port of the weightlessness measuring scale and connected with a controller; the feed inlet of the hazardous waste mixing machine is connected with the discharge outlet of the weightless metering scale through a pipeline.
Furthermore, the weightlessness weighing scale is in a bucket shape with a large upper part and a small lower part.
Furthermore, a feed inlet with the same size as the discharge opening of the bucket elevator is arranged at the top of the weightlessness measuring scale.
Further, the discharge opening of the bucket elevator is hermetically connected with the feed inlet of the weightless metering scale through a hose.
Further, the controller is a computer.
When the fly ash conveyor works, the computer controls the bucket elevator to start, and fly ash packaged by ton bags is conveyed to the weight-reducing weighing scale to realize the feeding function; the weighing sensor is an analog quantity signal, and the analog quantity signal is transmitted to a computer in the control system after signal conversion; the materials in the weight-reducing weighing scale are converted into digital signals through a sensor and a microcomputer and displayed; the computer controls the opening of the discharge door, and the fly ash with required weight is discharged into the mixer for physical and chemical treatment according to the decrement method metering mode.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a change measurement mode and conveying equipment structure, solve the technological problem that can't solve in the traditional flying dust mode of transportation, make the moist of ton bag packing or the flying dust of caking can carry and measure, accomplish the flow to the useless machine that mixes of danger smoothly.
