Description

Dust collection and recovery device for powder silo of concrete mixing plant

technical field

The utility model relates to a dust collection and recovery device, in particular to a dust collection and recovery device used in a powder silo of a concrete mixing station.

Background technique

Based on the process of transporting bulk cement trucks from concrete mixing stations to the powder silo, positive pressure and a large amount of dust will be generated in the silo. If not handled properly, it will have a serious impact on the surrounding environment. The dust collection of the traditional powder silo is to install the dust collector on the roof of the warehouse. Due to the high installation height, there are certain dangers and difficulties in maintenance and maintenance. The filter element is often blocked. When the safety valve is opened, dust from the roof of the warehouse will appear, and even a "roof fall" accident will occur.

The purpose of the utility model is to overcome the defects in the prior art, and provide a dust collection and recovery device for the powder silo of a concrete mixing station, which can effectively improve the dust collection effect of the powder silo and prevent the dust from escaping from the top of the silo.

The utility model is realized in the following way: a dust collection and recovery device for the powder silo of a concrete mixing station, which is characterized in that it includes a vertical dust collection pipeline 6, a horizontal dust collection pipeline 7, a recovery pipeline 4, a manual Plate valve 2, rotary feeder 3, Roots blower 1, powder bin 8, dust collector 5 fixed on the ground; the powder bin 8 is located above the dust collector 5, and the dust collector The dust collector 5 is connected to the powder bin 8 through the vertical dust collection pipeline 6 and the horizontal dust collection pipeline 7 connected to each other. A rotary feeder 3 is provided below the outlet of the dust collector 5. A manual flapper valve 2 is provided between the rotary feeder 3 and the outlet of the dust collector 5, and the rotary feeder 3 is connected to the Roots blower 1 and the powder silo respectively through the recovery pipeline 4. 8 connected.

The powder silo 8 includes a first cement silo 81, a second cement silo 82, a third fly ash silo 83, and a fourth mineral powder silo 84, and the dust collector 5 includes a first dust collector 51. The second dust collector 52, the first dust collector 51 is connected to the first cement silo 81 and the second cement silo 82 respectively through the vertical dust collection pipeline 6 and the horizontal dust collection pipeline 7 The second dust collector 52 is respectively connected to the third fly ash silo 83 and the fourth mineral powder silo 84 through the vertical dust collection pipeline 6 and the horizontal dust collection pipeline 7; The dust collector 51 is connected to the second dust collector 52 through the recovery pipeline 4 .

The beneficial effects of the utility model are: the dust collector of the utility model is placed on the ground, which greatly facilitates its maintenance and repair, prevents the occurrence of "roof fall" accidents, and protects personal and property safety; at the same time, the collected dust It can be recycled again to avoid the secondary pollution of dust to the environment and realize "zero" emission to the environment.

Detailed ways

According to Figures 1 to 3, the utility model includes a vertical dust collection pipeline 6, a horizontal dust collection pipeline 7, a recovery pipeline 4, a manual flapper valve 2, a rotary feeder 3, a Roots blower 1, and a powder Bin 8, dust collector 5 fixed on the ground; the powder bin 8 is located above the dust collector 5, and the dust collector 5 is connected to each other through the vertical dust collection pipeline 6 and the horizontal dust collector. The dust pipeline 7 is connected to the powder bin 8, a rotary feeder 3 is provided below the outlet of the dust collector 5, and a rotary feeder 3 is provided between the outlet of the dust collector 5 and the dust collector 5. Manual flapper valve 2, the manual flapper valve 2 is used to adjust the feeding speed of dust, the rotary feeder 3 is connected to the Roots blower 1 and the powder bin 8 respectively through the recovery pipeline 4 .

The powder silo 8 includes a first cement silo 81, a second cement silo 82, a third fly ash silo 83, and a fourth mineral powder silo 84, and the dust collector 5 includes a first dust collector 51. The second dust collector 52, the first dust collector 51 is connected to the first cement silo 81 and the second cement silo 82 respectively through the vertical dust collection pipeline 6 and the horizontal dust collection pipeline 7 The second dust collector 52 is respectively connected to the third fly ash silo 83 and the fourth mineral powder silo 84 through the vertical dust collection pipeline 6 and the horizontal dust collection pipeline 7; The dust collector 51 is connected to the second dust collector 52 through the recovery pipeline 4 .
