Abstract
The utility model provides a negative pressure dust removal system of an asphalt mixing plant, and is used for solving the problems that the existing negative pressure dust removal system of the asphalt mixing plant can not provide enough negative pressure for an asphalt mixing mainframe, the dust removal effect is not obvious and the like. The negative pressure dust removal system of the asphalt mixing plant comprises an asphalt mixing mainframe and a dust removal device, wherein the asphalt mixing mainframe comprises a vibrating screen, a hot aggregate bin, a mixing layer, a trolley bin and a finished product storage bin connected in sequence from top to bottom; the dust removal device comprises a dust removal fan, a dust removal main flue and a first negative pressure pipe; the dust removal fan is arranged at one end of the dust removal main flue, one end of the first negative pressure pipe is communicated with the vibrating screen, and the other end of the first negative pressure pipe is connected to the dust removal main flue through a circular truncated cone cylinder.
Description
Technical field
The utility model relates to a kind of dust arrester of bituminous mixing plant, particularly a kind of bituminous mixing plant depression dust-removing system.
Background technology
If it is negative pressure that asphalt concrete mixer can not ensure to stir the air pressure in each warehouse on main building in the time of work, more dust can leak in the processes such as metering stirring.Also having at present more asphalt mixing plant there is no negative pressure system, cause serious environment pollution, is also the dust pelletizing system of the equipment that is connected to of simply the place pipeline of easily revealing dust on main building being together in series and part has negative pressure system.The simple connection of this negative-pressure pipeline can not ensure in pitch main building, there are enough dedusting negative pressure.
Utility model content
The utility model proposes a kind of bituminous mixing plant depression dust-removing system, solve the problems such as existing bituminous mixing plant depression dust-removing system cannot provide enough negative pressure to asphalt mixing main building, and dust removing effects is not obvious.
The technical solution of the utility model is achieved in that
A kind of bituminous mixing plant depression dust-removing system, comprise asphalt mixing main building and dust arrester, described asphalt mixing main building comprises the vibrosieve, hot aggregate bin, stirring layer, dolly storehouse and the storage of finished products storehouse that connect successively from top to bottom, described dust arrester comprises dedusting fan, dedusting flue collector and the first negative tube, described dedusting fan is installed on one end of described dedusting flue collector, one end of described the first negative tube is communicated with described vibrosieve, and the other end is communicated in described dedusting flue collector by a round platform cylindrical shell.
Further, described dust arrester also comprises the second negative tube, and one end of described the second negative tube is connected in the top in described dolly storehouse, and the other end is communicated with described dedusting flue collector.
Further, described the first negative tube is connected to form by bend pipe by some single tubes, and the angle of bend of described bend pipe is greater than 90 °.
Further, the angle of bend of described bend pipe is 120 °.
Known by above description, the utility model compared with prior art, the utlity model has following advantage:
Negative pressure system of the present utility model, one end that the first negative tube is connected in dedusting flue collector is connected with a round platform cylindrical shell, frustum cone cylinder body can make the air quantity that enters negative tube entrance assemble, because air quantity is assembled increase, make in the time that wind enters negative tube, to form larger blast, ensureing has enough dedusting negative pressure in vibrosieve.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of bituminous mixing plant depression dust-removing system, comprise asphalt mixing main building 1 and dust arrester 2, described asphalt mixing main building comprises the vibrosieve 11, hot aggregate bin 12, stirring layer 13, dolly storehouse 14 and the storage of finished products storehouse that connect successively from top to bottom, described dust arrester 2 comprises dedusting fan (not shown), dedusting flue collector 23, the first negative tube 21 and the second negative tube 22, the first negative tube 21 is for the dedusting of vibrosieve 11, and the second negative tube 22 is for the dedusting in dolly storehouse 14.Described dedusting fan is installed on one end of described dedusting flue collector 23, and one end of described the first negative tube 21 is communicated with described vibrosieve 11, and the other end is communicated in described dedusting flue collector 23 by a round platform cylindrical shell 24.One end of described the second negative tube 22 is connected in the top in described dolly storehouse 14, and the other end is communicated with described dedusting flue collector 23.
Described the first negative tube 21 is connected to form by bend pipe 25 by some single tubes, when the less wind of the angle of turning round during through turning air loss larger, therefore the angle of bend of bend pipe of the present utility model is greater than 90 °.And the angle of working as bend pipe more approaches 90 degree, the bend pipe of the use of turning round is fewer, and in the time that the angle of bend pipe is 120 °, the bend pipe of use is less can ensure that again bend pipe is less to the resistance of blast, effectively reduces air loss.Therefore, preferred, the angle of bend of described bend pipe is 120 °.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
