Description
Technical field
This utility model relates to colliery engineering field of mechanical technique, relates in particular to a kind of spray dust remover and development machine.
Background technology
At present, in coal industry, mine laneway excavation operation uses development machine to complete in a large number, to realize the high-yield and high-efficiency of coal mining enterprise, development machine is in the process of driving, owing to broken rib can produce substantial amounts of coal dust, the healthy of working face personnel is not only caused great harm by these coal dusts, it is possible to cause the occupation disease such as anthracosis, and substantial amounts of coal dust also can bring the hidden danger of coal-dust explosion.Further, since be flooded with coal dust in the working environment of down-hole, necessarily also affecting the sight line of staff, and then affect work efficiency, therefore, development machine dedusting work in tunneling process just seems extremely important.
At present, the depositing dust mode that development machine adopts is generally divided into internal spraying depositing dust and external spraying depositing dust two kinds, and inner spraying nozzle is short due to jet length, angle of flare is little, and adopt restraints shape or sector more, acts primarily as cooling pick, pick and coal petrography is suppressed to collide the dust caused, dust controlling is limited.External spraying nozzle is generally installed in two ears of cutting units, nozzle adopts ejection type or umbrella shape injection, main in order to trap the dust flown upward, yet with dust, there is certain hydrophobicity, causing the fog screen that external spraying is formed also to be difficult to whole dust settlings, part dust escapes out fog screen to external diffusion, therefore, need a kind of new dust arrester of design badly, to overcome drawbacks described above.
Utility model content
For all deficiencies of prior art, in order to solve the problems referred to above, it is proposed that a kind of simple in construction, the spray dust remover of good dedusting effect and development machine, thus effectively reducing the Dust Concentration of development machine working space.
The technical solution adopted in the utility model is as follows:
A kind of spray dust remover, including airflow injection case, spray nozzle and blower fan, described airflow injection case is provided with air inlet and jet pipe, and described spray nozzle is arranged in jet pipe, and described blower fan is connected with airflow injection case by ventilation duct.
Further, described spray nozzle is set to fan-spray mouth, hollow cone spray nozzle or solid-cone spray nozzle.
Further, the water smoke diameter of described spray nozzle ejection is not less than the internal diameter of jet pipe.
Further, described air inlet is provided with protective cover.
Further, described protective cover is evenly distributed with air-vent.
This utility model also provides for a kind of development machine, and described development machine includes above-mentioned spray dust remover.
The beneficial effects of the utility model are:
1, this utility model is provided with airflow injection case, can be sucked from air inlet by dusty gas, make the dust of suction be subject to the shock repeatedly of water smoke in jet pipe, condense with droplet, after ejection, lose skyborne suspending power, quickly settle down, thus reaching the effect of depositing dust；
2, this utility model is provided with the blower fan being connected with airflow injection device, can make to be formed in airflow injection case negative pressure, so that in dusty gas suction airflow jet box, the dusty gas that blower fan sucks can be discharged to outside working region, has also functioned to dustproof function simultaneously.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with accompanying drawing of the present utility model; the technical solution of the utility model is carried out clear, complete description; based on the embodiment in the application; other similar embodiment that those of ordinary skill in the art obtain under the premise not making creative work, all should belong to the scope of the application protection.
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
Embodiment one:
nullAs shown in Figure 1，A kind of spray dust remover，What be arranged on development machine cuts two ears every portion，Including airflow injection case 1、Spray nozzle 4 and blower fan 6，Described airflow injection case 1 is provided with air inlet 2 and jet pipe 3，Described spray nozzle 4 is arranged in jet pipe 3，Described blower fan 6 is arranged on outside development machine working region，It is connected with airflow injection case 1 by ventilation duct 5，Dusty gas can be drawn in airflow injection case from air inlet 2 by blower fan 6 work，In Fig. 1 " → " represent dusty gas flow direction，A portion dusty gas enters in jet pipe 3，Under the shock repeatedly of the water smoke of spray nozzle 4 ejection，Condense with droplet，After ejection，Lose skyborne suspending power，Quickly settle down，Thus reaching the effect of depositing dust，Another part dusty gas is discharged to outside development machine working region by ventilation duct 5.
nullAs shown in Figure 2，Described air inlet 2 place is provided with protective cover 7，Described protective cover 7 is evenly distributed with air-vent 8，Described protective cover 7 can stop that spoil and coal enter in airflow injection case 1，Serve protective effect，Air-vent 8 can ensure that dusty gas enters in airflow injection case smoothly simultaneously，Described spray nozzle 4 is set to fan-spray mouth、Hollow cone spray nozzle or solid-cone spray nozzle，In the present embodiment，Spray nozzle 4 is set to fan-spray mouth，The water smoke diameter of described spray nozzle 4 ejection is not less than the internal diameter of jet pipe 3，When described spray nozzle 4 is to external spraying，Owing to water smoke diameter is not less than the internal diameter of jet pipe 3，Just water smoke piston is defined，The air in jet pipe 3 front is released endlessly by water smoke，Vacuum is formed in rear air-flow jet box 1，Thus form negative pressure at air inlet 2 place，Even if blower fan 6 does not work，Also can make in dusty gas suction airflow jet box.
Below this utility model is described in detail, the above, be only the preferred embodiment of this utility model, when not limiting this utility model practical range, namely all done impartial change according to the application scope and modified, all should still be belonged in this utility model covering scope.
