The concrete mixing plant is a combined device for intensively mixing concrete, and is also called a concrete precast yard. Because of its high degree of mechanization and automation, it has high productivity, can ensure the quality of concrete and save cement, and is commonly used in large and medium-sized water conservancy projects, electric power projects, bridges and other projects with large concrete engineering quantity, long construction period and centralized construction sites. With the development of municipal construction, the mixing plant which adopts centralized mixing and provides commercial concrete has great superiority, thereby being developed rapidly and creating conditions for promoting concrete pumping construction and realizing combined operation of mixing, conveying and pouring machines. At present, cement, fly ash and gravel are generally stored in storage bins of a concrete mixing plant respectively, and the storage bins and a spiral feeder are matched for use to convey raw materials to various positions. In order to prevent the raise dust from being generated in the storage bin, a dust removal device is generally arranged on the top of the storage bin, and air in the storage bin is discharged to the atmosphere after passing through the dust removal device.

However, in the existing dust removal of the storage bin, dust passes through a filter cloth bag in a dust remover, and a vibrator shakes off the dust at intervals, so that large-particle dust and fine-particle dust cannot be screened, and the dust removal effect is poor; at present, more and more concrete mixing plants are in a loading and unloading mobile type, and the dust removal device of the concrete mixing plant also needs to be conveniently matched with the concrete mixing plant for use.

Furthermore, the water curtain filtering device comprises a reservoir, a water inlet pipeline, a water curtain, a drainage pipeline and a water pump which are sequentially and circularly communicated, wherein the water curtain completely covers the section of the tail end of the dust collection pipeline.

Further, the angle of the acute angle included angle between the dust screening pipeline and the horizontal plane is larger than that between the dust suction pipeline and the horizontal plane.

Further, the first fan and the second fan are both axial fans.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model provides a concrete mixing plant dust collector, which is provided with a fan device capable of absorbing dust, and large-particle dust is settled and screened by an inclined dust absorption pipeline with branches, fine-particle dust is removed by a water curtain type adsorption purification device, and dust discharge can be effectively treated; the device simple structure, main dust rose box and dust collection box all can install on main building, and it directly only need be connected through the pipeline with the storage silo, simple to operate is fit for portable concrete mixing plant and removes dust when arranging with the different forms in different places.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example 1, see FIGS. 1-3: the utility model relates to a concrete mixing plant dust collector, device install on storage silo 1 and main building 15, the agitated vessel in feed through feed screw 16 to main building 15 is carried out to the bottom of storage silo 1. The top of storage silo 1 is provided with dust absorption pipeline 2, dust absorption pipeline 2 the head end with storage silo 1 intercommunication, and be the slope setting that the head is high tail low, dust absorption pipeline 2 the head end be provided with be used for to produce the first fan 3 of negative pressure in the storage silo 1, the intercommunication is equipped with two dust screening pipelines 4 on the dust absorption pipeline 2.
