Description

Aggregate dust removing device for large concrete mixing plant Technical Field The invention relates to the field of dust removal devices, in particular to an aggregate dust removal device for a large-scale concrete mixing plant. Background The large concrete mixing plant is equipment for concrete construction engineering and is used for mixing mixed concrete. The concrete mixing station mainly comprises five components of a mixing host machine, a material weighing system, a material conveying system, a material storage system, a control system and other auxiliary facilities, and the main principle of the concrete mixing station is to mix and stir raw materials such as sand, lime and cinder with cement as cementing materials, and finally prepare concrete which is used as wall materials and infrastructure construction engineering. Concrete aggregate is an important component in concrete structures and is a granular loose material. They are typically made of natural sand, artificial sand, cobble, etc., for filling voids in the concrete and enhancing the strength of the concrete. The main function of concrete aggregates is to support the concrete structure and to form a strong base concrete aggregate after curing of the concrete, the classification of which is generally carried out according to their particle size, the particle diameter of coarse aggregates is generally greater than 5 mm, such as gravel, crushed stone, etc., and the particle diameter of fine aggregates is generally less than 5 mm, such as natural sand, artificial sand, etc. In addition, concrete aggregates may be classified according to their use, for example, concrete aggregates for road construction, concrete aggregates for construction engineering, and the like. Because a large amount of dust is doped in the aggregate, the aggregate needs to be dedusted through a dedusting device when the aggregate is conveyed and processed, the dedusting device is used for controlling a series of equipment and processes for dust pollution generated by a concrete mixing plant, the equipment and processes can remove the dust generated by the concrete mixing plant in different modes, including methods of gravity sedimentation, electrostatic absorption, wet dedusting, pulse blowing and the like, and the wet dedusting is to mix the dust with water and settle the dust to the bottom through water mist or water curtain, so that the method is suitable for processing a large amount of dust and can effectively remove fine dust. The Chinese patent application CN112933829A discloses a dust removing device in the aggregate screening process, which comprises a screening machine body, a feeding pipe, a feeding hopper, a cleaning cover, a disassembling bolt, a machine leg, a drainage valve, a control panel, a sealing strip, an observation window and a screening discharging pipe, wherein the feeding hopper is connected to the inlet of the left upper side of the screening machine body through the feeding pipe, the cleaning cover is arranged at the left end of the screening machine body, the cleaning cover is fixedly connected with the cleaning bolt, an aggregate inlet pipe, a splash-proof cover, a spraying box, a spraying row, a dust-falling water nozzle and a connecting pipe head are arranged, the aggregate raw materials entering the dust-falling operation is favorably sprayed, dust is prevented from flying, the aggregate raw materials are introduced into the spraying box through the splash-proof cover, and then the water pipe is connected with the connecting pipe head according to the dust quantity, so that water can be sprayed and discharged through the dust-falling water nozzle through spraying, the dust-falling effect is played, and the dust-proof effect is ensured. The above-mentioned patents and prior art also have the following drawbacks: The dust on the aggregate is flushed down through spraying, the aggregate does not move and rub each other, the cleaning effect to the dust is poor, the dust treatment effect is poor, the cleaning water mixed with the dust needs to be recycled or recycled after being separated, the mode of natural sedimentation is adopted for consuming too long, the floor area of sedimentation setting is large, the practicability is low, the filter screen cloth is easy to block by adopting the filter screen cloth filtering mode, and the continuous filtering capability is poor. Accordingly, the present application provides an aggregate dust removal device for a large concrete mixing plant to meet the needs. Disclosure of Invention The application aims to provide an aggregate dust removing device for a large concrete mixing plant, which is used for cleaning aggregate through cleaning water, so that dust on the aggregate is thoroughly treated, a large amount of dust is prevented from being raised in the subsequent conveying and treating processes of the aggregate, the cleaning water and sludge can be continuously separated, a filter cloth belt has a co
