Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1 and 2, the present embodiment provides a ballast treatment apparatus, which includes a ballast scooping machine 10, a screening machine 11, a large ballast conveyor belt 12, a small ballast conveyor belt 13, a first iron remover 14, a second iron remover 15, and a washing nozzle 16. The slag scooping machine can be a scraper slag scooping machine or a spiral slag scooping machine, wherein the scraper slag scooping machine is mainly used for separating solid matters with certain granularity from a liquid and solid mixture. It is a continuous and efficient mechanical deslagging device, and is commonly used in the occasions of separation or solid-liquid separation. Such as: boiler deslagging systems, river dredging systems, and the like. The embodiment is used for conveying the ash to the screening machine. The screening machine can be a small-sized vibrating sand screening machine with the model number of SSF-80, and is manufactured by Shunchang mechanical factories in Julu county. Concretely, divide the screen (ing) machine mainly by shock dynamo, the screen cloth, a spring, base and sieve are fought, install a plurality of springs between sieve fill and base, the screen cloth is installed in the sieve fill, the sieve mesh diameter of screen cloth can be set for by oneself, the sieve mesh diameter of screen cloth is 40mm in this embodiment, install shock dynamo on the base, and shock dynamo's output is installed on the sieve fill, when consequently opening shock dynamo, the sieve fill can vibrate through the spring, make the grits that lie in the sieve fill pass through the screen cloth and divide the sieve then, reach the purpose of dividing the grits. The screening of the ash slag can facilitate the burning of different burning furnaces, thereby improving the burning efficiency.

In order to avoid the ash residue from scattering on the bottom surface when the residue scooping machine conveys the ash residue to the screening machine, the screening machine is provided with a feed hopper 111, and the ash residue can be concentrated on one end of the screening machine to be gradually screened through the feed hopper until the ash residue is discharged from the outlet at the other end of the screening machine, so that the purpose of fully screening the ash residue is achieved.

In order to fully screen and clear the sludge and/or dust on the ash, a washing spray head is arranged above the screening machine. When the ash residue is conveyed into the screening machine through the top of the screening machine by the residue scooping machine, the washing spray head is opened, so that the screening machine can wash the ash residue when vibrating and screening the ash residue. And for the washed wastewater, the wastewater is directly discharged on the ground, and the wastewater is collected by digging a ditch on the ground so as to be treated in a centralized manner. The sieved ash is output through two outlets of the sieving machine, and the larger ash blocks on the screen of the sieving machine are conveyed to a large ash conveying belt through an outlet at the end part of the sieving machine. And the smaller ash blocks after screening are directly conveyed to a small ash conveying belt from a bottom outlet of the screening machine, so that the purpose of screening the ash is realized.

And after the ash is sieved, removing the iron objects in the ash through the first iron remover and the second iron remover. The first iron remover and the second iron remover have the same structure, so the first iron remover can be described in detail, the first iron remover and the second iron remover can be self-unloading electromagnetic iron removers, the models of the first iron remover and the second iron remover can be RCDC-5 or RCDC-6, and the first iron remover and the second iron remover are manufactured by Weifang Feisite autonomous control equipment Limited. The first iron remover comprises a crane frame 141, a hanging wheel 142 and an electromagnetic iron remover 143, the crane frame is positioned at one side of the large-block ash conveying belt, the electromagnetic iron remover is suspended and fixed above the large-block ash conveying belt through the hanging wheel and a traction rope 144, and current is led into the electromagnetic iron remover, so that the electromagnetic iron remover can adsorb iron objects, the iron objects in the ash are removed, and the removed large ash blocks are conveyed into the large-block ash collecting box 121 at the tail end through the large-block ash conveying belt. Similarly, the small ballast conveyor belt conveys the screened small ballasts, the second iron remover removes the iron objects in the ballasts, and the removed small ballasts are conveyed to the small ballast collecting box 131 at the tail end through the small ballast conveyor belt. The purposes of screening the ash, clearing the iron objects and storing the iron objects are achieved, so that the damage of incineration caused by the iron objects can be effectively avoided in the subsequent incineration procedure, the problem that the bearing of the incinerator exceeds the standard is avoided, and the incineration cost is reduced.
