Description
Technical Field
The utility model belongs to the technical field of concrete mixing plants, and particularly relates to a dust removal device for a mixing main building of a concrete mixing plant.
Background
The concrete mixing plant is a complete set of equipment which is used for weighing and metering raw materials such as sand, stone, cement, water, additives and the like according to a certain proportion and then putting the raw materials into a mixing host machine for mixing into uniform finished concrete. The weighed sand and stone are lifted by a lifting belt conveyor, then are discharged into a transition bin above the stirring main machine, and are put into the stirring main machine together with the weighed cement, water and additives for stirring when the stirring is needed. The stirred finished concrete is unloaded into a stirring and conveying vehicle by dead weight and is conveyed to each construction site for use. When sand and stone fall into the transition bin, a large amount of dust is generated and falls into the stirring building; when sand and stones are put into the stirring main machine from the transition bin, the closed space of the stirring main machine is compressed, and a large amount of dust is generated and drifts around.
In order to eliminate the dust, a common manufacturer installs a dust remover with a fan on a stirring main machine cover, as shown in fig. 1, negative pressure is generated in the stirring main machine due to the suction of the fan, the dust in the stirring main machine is sucked into the dust remover, the gas in the dust is cleaned and discharged into the atmosphere after the filtration of the dust remover, and the dust is blocked and falls into the stirring machine under the action of gravity.
Such a dust collector has two problems: firstly, dust generated when sand and stone are discharged to a transition bin cannot be eliminated, so that the dust in a stirring main building is scattered, and the environment is seriously polluted; second, because the tie point position of dust remover and stirring owner cover is low, the mud of raising when the stirring host computer stirs, very easy bonding is in the junction of dust remover and stirring cover, and it is more serious to amass more, blocks dust airflow channel completely at last, leads to the dust removal inefficacy.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the dust removal device for the main mixing plant of the concrete mixing plant, which removes dust caused by unloading of a lifting belt conveyor and solves the dust pollution of the main mixing plant, and has good dust removal effect and low cost.
The utility model aims to realize the dust removal device for the main mixing plant of the concrete mixing plant, which comprises a main mixing plant, a transition bin and a lifting belt conveyor.
Compared with the prior art, the utility model has the following remarkable characteristics and positive effects: the dust remover comprises a transition bin, a dust collector, a belt conveyor, a dust collecting device and a dust collecting device, wherein the top of the transition bin is provided with a negative pressure fan, a short dust collecting bag and a long dust collecting bag; meanwhile, the dust-containing air flow generated in the stirring main machine passes through the dust channel and is filtered by the long dust removal cloth bag, and is exhausted into the atmosphere from the negative pressure exhaust fan. The utility model cancels the original dust remover which only removes dust of the stirring main machine, designs the dust remover which removes dust of the stirring main machine and dust caused by unloading of the lifting belt conveyor on the transition bin cover, has almost no cost difference, removes dust of two dust sources by one set of device, solves the dust pollution generated by unloading of the lifting belt conveyor and solves the dust pollution of the stirring main building.
