Description

The concrete mixing plant dust arrester
Technical field
The utility model relates to the improvement to dust arrester in the concrete production processing.
Background technology
Along with ready-mixed concrete has obtained developing rapidly and applying in national big and medium-sized cities, concrete mixing plant has also obtained high speed development.Intellectuality, environmental protection, high precision int become the developing direction of concrete mixing plant.
Concrete mixing plant in process of production because the conveying of powder and store and can produce a large amount of dust, these dust emissions in the atmosphere after serious environment pollution.Simultaneously, dust lands the soda acid that causes underground water, brings harm for industrial production and people's lives.Traditional dedusting method is to offer ventilation tube at the container top of powder storage and powder weighing to reach the purpose that reduces dust pollution, as shown in Figure 3, ventilation tube of the prior art generally is comprised of metal framework 15 and canvas bag 16, because canvas bag easily absorbs water and pore is thick, cement forms bonding obstruction, cause pressure reduction large, dust removing effects is poor, and is unfavorable to keeping the safety in production.
The utility model content
The utility model is for above problem, and a kind of concrete mixing plant dust arrester of simple in structure, high-effective dust-removing is provided.
The technical solution of the utility model is: described concrete mixing plant comprises that conveying worm, powder weighing device, sandstone treat hopper, mixer and dust arrester, and described powder weighing device is connected that with sandstone top and bottom that hopper is located at respectively described mixer connect respectively described mixer;
Described dust arrester is located at described powder weighing device and sandstone is treated between the hopper, comprises deduster, air inlet pipe and blower fan, and described deduster one end connects described mixer, and an end connects described blower fan; Be provided with filter core in described deduster, described air inlet pipe is communicated with described deduster and between described filter core and blower fan.
Described sandstone treats that the top of hopper or side connect described deduster by dust collection pipe.
The top of described powder weighing device connects described mixer by blast pipe.
The utility model is provided with dust arrester in concrete mixing plant, the dust absorbing of effectively powder weighing device and sandstone being treated to produce in the hopper is in deduster, utilize simultaneously air inlet pipe to pass into the dust that compressed air will accumulate on the filter core and pour in the mixer, guaranteed that the dust circulation is smooth and easy.When the utility model improved the dust pollution phenomenon greatly, the running precision of equipment had had assurance, and overall performance effectively promotes.
Description of drawings

Fig. 3 is the structural representation of ventilation tube in the prior art;
1 is conveying worm among the figure, the 2nd, and powder weighing device, the 3rd, air inlet pipe, the 4th, deduster, the 5th, blower fan, the 6th, dust collection pipe, the 60th, pipe outlet, the 7th, bellows, the 8th, sandstone is treated hopper, the 9th, plaster blanking port, the 10th, mixer, the 11st, cement charging aperture, the 12nd, flyash charging aperture, the 13rd, blast pipe one, 14th, blast pipe two, the 15th, metal framework, the 16th, canvas bag.
The specific embodiment
The utility model is shown in Fig. 1-2, described concrete mixing plant comprises that conveying worm 1, powder weighing device 2, sandstone treat hopper 8, mixer 10 and dust arrester, and described powder weighing device 2 is connected that with sandstone top and bottom that hopper 8 is located at respectively described mixer 10 connect respectively described mixer 10;
Described dust arrester is located at described powder weighing device 2 and sandstone is treated between the hopper 8, comprises deduster 4, air inlet pipe 3 and blower fan 5, and described deduster 4 one ends connect described mixer 10(and connect mixer 10 by bellows 7), an end connects described blower fan 5; Be provided with filter core in described deduster 4, described air inlet pipe 3 is communicated with described dedusters 4 and between described filter core and blower fan 5.
Described sandstone treats that the top of hopper 8 or side connect described deduster 4 by dust collection pipe 6, and as shown in Figure 1, pipe outlet 60 is connected on the deduster 4 by pipeline coupling flange.
The top of described powder weighing device 2 connects described mixer 10 by blast pipe.Powder weighing device 2 comprises cement bin and fine coal ash silo, be respectively equipped with cement charging aperture 11 and flyash charging aperture 12 at cement bin and fine coal ash silo, wherein cement bin connects mixer 10 by blast pipe 1, and the fine coal ash silo connects mixer 10 by blast pipe 2 14.
Described mixer 10 is provided with blast pipe is connected the plaster blanking port 9 that is connected with bellows.
Deduster 4 preferred pulse back flushing type dedusters in the utility model.
The utility model course of work is: deduster 4 places powder weighing device 2 and sandstone to treat between the hopper 8, and sandstone treats that hopper 8 is connected to form the passage I of gathering dust by dust collection pipe 6, flange and deduster 4; Powder weighing device 2 tops are provided with blast pipe, are communicated with by blast pipe, plaster blanking port 9 and mixer 10, are connected to form the passage II of gathering dust through bellows 7 and deduster 4 again; The outlet of deduster lower taper is communicated with by bellows 7, plaster blanking port 9 and mixer 10, forms the main passage that gathers dust, and this passage also is the dust blanking channel when the cleaning filter core simultaneously.Cement, flyash are sent in the powder weighing device 2 by conveying worm 1 during mixing plant work, meanwhile sand material is knocked down sandstone by belt conveyor and is treated in the hopper 8, the a large amount of dust of middle generation of feeding intake are sucked by fan of dust remover by the passage I of gathering dust, II and are attached to cartridge surface, and its dust flow direction as shown by arrows in FIG..Cleaning blowback to filter core can be set working time and blanking time by pulse control instrument according to different dust concentrations, and the dust that cleaning falls directly falls in the agitator tank along bellows 7 and stirs with concrete.
The cleaning system of this deduster 4 adopts Pulse-jet Cleaning Controller, its operation principle is as follows: by the opening and closing of pulse control instrument automatic control electric magnet valve, compressed air is sprayed into filter core, the impulsive force that compressed air produces makes filter cloth outwards expansion and contraction of moment, thereby the broken filter core that breaks away from of the dust that cartridge surface is piled up, filter core recovers draught capacity, and the user also can set pulse backblowing blanking time as required.
