Description

Technical Field

[0001] The invention belongs to the technical field of dust treatment, and in particular relates to a dust removal ash treatment device. Background Art

[0002] The dust collected by dust collectors in domestic mineral processing plants is usually transported by pneumatic conveying, dust tank trucks, or by car after a humidifier.

[0003] Pneumatic conveying has the following main disadvantages: 1. High power consumption; 2. Components in contact with airflow and materials in the conveying pipeline are subject to severe wear, especially when conveying abrasive materials; 3. There are certain restrictions on the conveying materials. For example, pneumatic conveying cannot be used for brittle and fragile materials because breakage will lead to quality degradation or unqualified products; pneumatic conveying is not suitable for sticky materials or materials that are easy to absorb moisture and agglomerate because they are easy to block the pipe during the conveying process.

[0004] At the same time, the transportation of dust by tank trucks and the transportation by car after the humidifier require a lot of manpower, which is very inconvenient to operate.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

Three groups of hydraulic nozzles 8 are arranged on the clean water pipe 7 that enters the mortar tank 4. A stirring device and a mortar pump 5 are also arranged in the mortar tank 4. The mortar pump 5 is arranged in a simple pump room 12 next to the mortar tank 4, and then the slurry in the mortar tank 4 is sucked away by extending the mortar suction pipe 13 into the mortar tank 4.

[0031] In the above embodiment, the clean water pipe 7 is connected from the ore dressing plant to the slurry tank 4, and the slurry in the slurry tank 4 is connected to the concentration tank or the main plant process system by the slurry pump 5 through the mud pipe 11. In this way, the structure of the present invention is suitable for the plant area of ​​the ore dressing plant in the mining industry that needs to collect and process the dust after being processed by the dust collector, and the dust is converted into slurry and transported to the concentration tank or the main plant process system. The configuration is simple, which can reduce the secondary pollution of dust transportation, reduce the project cost, and realize automatic operation.

[0032] A preferred embodiment of the present invention provides a dust ash processing device, in which an ash discharge valve 2 is provided on the ash outlet of the dust collector ash hopper 1, and a slurry concentration sensor 16 is provided in the slurry tank 4; in the present invention, the slurry concentration sensor 16 controls the mud concentration to be about 30% to 35%. Specifically, the mud concentration is achieved within the range of 30% to 35% through the start and stop control of the ash discharge valve 2, hydraulic nozzle 8, ash conveyor 3, stirring device, and mud pump, all of which are controlled by the PLC interlock to start and stop the related motor 9.

[0033] For example, the hydraulic nozzle 8 and the ash conveyor 3 are started at the same time, and the ash conveyor 3 stops spraying water two minutes after stopping running, and the stirring device is stopped two minutes after the hydraulic nozzle 8 stops spraying water, so that no excess dust will remain. In addition, the ash conveyor 3 runs intermittently according to the ash storage capacity of the dust collector ash hopper 1.
