Abstract
The utility model discloses a high-efficiency dust collection device for crushing as-fired coal of a coking plant, which comprises two crushers (1), two feeding pipes (2), a main dust sucking pipe (3), a belt conveying chamber (4) and a suction hood (5). The high-efficiency dust collection device is characterized in that two ends of a circulating air channel (8) are respectively connected with the two feeding pipes (2), a dust sucking branch pipe (6) is arranged on the main dust sucking pipe (3) and connected with an auxiliary suction hood (7), and the auxiliary suction hood (7) is disposed on the belt conveying chamber (4). By the aid of the high-efficiency dust collection device, the pressure of an integral system is reduced, dust blockage in the dust sucking pipe is greatly reduced, dust escape is also remarkably decreased, accordingly, an operating environment of a belt corridor is purified, and pollution to surrounding environments is reduced.
Description
Technical field
The utility model relates to the improvement of a kind of coke-oven plant with dust arrester, and specifically go into the fragmentation of stove coal and uses the high-effective dust-removing device a kind of coke-oven plant.
Background technology
The coke-oven plant is a coal chemical industry enterprises, carries out in the broken transportation using dust arrester to carry out dedusting, the prior dedusting device going into the stove coal; As shown in Figure 1, comprise that two disintegrating machines 1, feed pipe 2, main sweep-up pipe 3, belt conveying room 4 and 5, two disintegrating machines 1 of dust shield are connected with corresponding feed pipe 2 respectively; Its discharge nozzle is connected with belt conveying room 4 respectively, and belt conveying room 4 is provided with belt housing, leaks to prevent dust; End at belt conveying room 4 is provided with dust shield 5, and dust shield 5 is connected with main sweep-up pipe 3, goes into the stove coal when carrying out fragmentation 1 pair of disintegrating machine like this; The dust and the coal dust material that produce together get into belt conveying room 4, transfer out through belt, and the dust in belt conveying room 4 is discharged through dust shield 5, main sweep-up pipe 3; Its weak point is: in running, two disintegrating machines 1 are that one of a job is subsequent use, and disintegrating machine 1 tup of rotation can produce very big air-flow at a high speed; A large amount of dust are floating in air, and most of dust can get into sack cleaner through the main sweep-up pipe 3 of dedusting fan, in this process; Wherein a part of dust deposits in main sweep-up pipe 3, and easy blocking master's sweep-up pipe 3 influences dust removing effects; And another part dust can be gone out belt housing, and dust escapes the operating environment that has both worsened belt porch, and also the atmosphere to periphery pollutes.
Summary of the invention
The purpose of the utility model be to provide a kind of simple in structure, need not to clear up dust sucting pipeline, go into the fragmentation of stove coal and use the high-effective dust-removing device and reach the good coke-oven plant of dust removing effects.
In order to reach above purpose, the technical scheme that the utility model adopted is: go into the fragmentation of stove coal and use the high-effective dust-removing device this coke-oven plant, comprises two disintegrating machines, feed pipe, main sweep-up pipe, belt conveying room and dust shield; Two disintegrating machines are connected with corresponding feed pipe respectively, and its discharge nozzle is connected with the belt conveying room respectively, and the belt conveying room is provided with belt housing; Dust shield is connected with main sweep-up pipe; On the belt conveying room, be provided with dust shield, it is characterized in that: the two ends of circulation air path are connected with two feed pipes respectively, on main sweep-up pipe, are provided with dust suction and are in charge of; Dust suction is in charge of with secondary dust shield and is connected, and secondary dust shield is located on the belt conveying room.
The utility model is also implemented through following measure: described dust shield is located at the middle part of belt conveying room, and described secondary dust shield is provided with two, and symmetry is located at the both sides of dust shield respectively.
The beneficial effect of the utility model is: compare with present dust arrester; Formed balanced pressure in the whole broken dust pelletizing system; Thereby reduced the pressure of whole system, so the dust stopping state in the sweep-up pipe has significantly reduced, dust escapes also and has obviously reduced; Thereby purified the operating environment of belt porch, reduced pollution surrounding environment.

Fig. 2 is the structural representation of the utility model;
Among the figure: 1, disintegrating machine; 2, feed pipe; 3, main sweep-up pipe; 4, belt conveying room; 5, dust shield; 6, dust suction is in charge of; 7, secondary dust shield; 8, circulation air path.
The specific embodiment
Make the utility model with reference to accompanying drawing 2.Go into the fragmentation of stove coal and use the high-effective dust-removing device this coke-oven plant, comprises that two disintegrating machines 1, feed pipe 2, main sweep-up pipe 3, belt conveying room 4 and 5, two disintegrating machines 1 of dust shield are connected with corresponding feed pipe 2 respectively; Its discharge nozzle is connected with belt conveying room 4 respectively, and belt conveying room 4 is provided with belt housing, leaks to prevent dust; Dust shield 5 is connected with main sweep-up pipe 3; On belt conveying room 4, be provided with dust shield 5, it is characterized in that: the two ends of circulation air path 8 are connected with two feed pipes 2 respectively, on main sweep-up pipe 3, are provided with dust suction and are in charge of 6; Dust suction is in charge of 6 and is connected with secondary dust shield 7; Secondary dust shield 7 is located on the belt conveying room 4, absorbs the dust of belt conveying room 4 simultaneously through dust shield 5 and secondary dust shield 7, and dedusting is not more thoroughly totally like this.
Described dust shield 5 is located at the middle part of belt conveying room 4, and described secondary dust shield 7 is provided with two, and symmetry is located at the both sides of dust shield 5 respectively.
The utility model is to be provided with circulation air path 8 through the middle part at the feed pipe 2 of two disintegrating machines 1, and air-flow formation circulated air in two disintegrating machines (opens is equipped with) that the tup of rotation is at a high speed produced makes disintegrating machine 1 dedusting fan housing internal pressure relative equilibrium; Disintegrating machine 1 tup of running produces powerful air-flow simultaneously, and air-flow is from disintegrating machine 1 most of belt conveying room 4 that gets into, and a part gets into circulation air path 8; Get into another disintegrating machine 1, get into belt conveying room 4 at last, form circulated air; And two secondary dust shields 7 setting up; With dust shield 5 balanced pressure in the belt conveying room 4, cause that outside pressure also reduces thereupon in the belt conveying room 4, stopped dust and escaped.
