Description
Technical Field
The utility model relates to the field of industrial dust prevention, in particular to an unpowered point type dust removal device.
Background
In the underground coal mine, a large amount of dust is generated in the links of coal mining, tunneling, transportation and supporting, and due to the limited underground space, the dust is difficult to completely diffuse out, so that the dust concentration is too high. In the production of coal mines, besides coal mining, tunneling, transportation and supporting links, a large amount of dust is generated, in scattered operations, for example, a certain amount of dust is generated in a rock cutting gate, punching and the like, and at the moment, large-scale dust removing equipment and a large-scale dust removing system are not suitable for configuration due to space or cost reasons, so that the dust generated in the operation can cause health hazards to operating personnel, and the concentration of the dust in the coal mines and the danger of dust explosion are increased. PTFE film is adopted by the Haochao to replace the traditional fiber filter cloth, and the novel mining dry dust remover is designed, and has the advantages of high filtering precision, long service life, high dust removing efficiency and the like; patent CN208153047U discloses a portable mining dust remover, but the power of the dust remover comes from a storage battery, so that the dust remover has certain danger in the underground coal mine, and the continuous operation capability is influenced by the electric quantity of the storage battery; patent CN207871830U discloses a wet pneumatic dust collector for mining, but the dust collector has a large volume and is not suitable for dust collection in narrow space and point type dust source; therefore, a small, portable, and independent power-free dust removal device is needed to remove dust from such a point dust source.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an unpowered point type dust removal device to solve the problem of a point type dust source with a narrow space and achieve the purpose of protecting the health of operators and the safety of a coal mine.
In order to solve the problems, the utility model provides an unpowered point type dust removal device which mainly comprises a dust collection box and a dust removal box, wherein the dust collection box comprises a venturi tube, an air supply duct and a protective cover, the dust removal box comprises a nozzle, a filter screen, a corrugated plate and a sewage discharge outlet, the power of the dust remover is derived from an underground compressed air self-rescue system, and the water source of the nozzle is derived from a mine water supply rescue system.
Preferably, said venturi tubes are arranged according to a circle, six in number.
Preferably, the sewage draining outlet is installed by a quick through connector of KJ25 type.
The working principle and the process are as follows: adopt the pressure wind system in the pit as power, high-speed wind pressure passes through the venturi tube and forms the negative pressure region, collects the dust to the dust removal case through wind channel and the inlet scoop of arranging at the dust source, crosses spraying, filter screen and buckled plate through twice in the dust removal case and deposits the dust, is discharged away by the slush pump at last.
The utility model has the beneficial effects that: the utility model has simple structure, good stability, small volume, light weight, no need of an external power source, unlimited continuous operation time and capability of effectively processing point type dust sources with narrow space.
Drawings
FIG. 1 is a front view of the present invention;
FIG. 2 is a top view of the present invention;
FIG. 3 is a left side view of the present invention;
in the figure: the device comprises a venturi 1, an air supply pipe 2, a protective cover 3, a dust collection box 4, a nozzle 5, a filter screen 6, a dust removal box 7, a sewage discharge outlet 8 and a corrugated plate 9.
Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-3, the unpowered point type dust removing device of the present invention comprises a 4 dust collecting box and a 7 dust removing box, wherein the 4 dust collecting box comprises a 1 venturi tube, a 2 air supply duct and a 3 protective cover, and the 7 dust removing box comprises a 5 nozzle, a 6 filter screen, a 9 corrugated plate and an 8 sewage outlet. This device is through adopting the pressure wind system in the pit as power, and high-speed wind pressure passes through the venturi tube and forms the negative pressure region, collects the dust to the dust removal case at the inlet scoop that the dust source was arranged, deposits the dust through spraying, 6 filter screens and 9 buckled plates in the dust removal incasement, is discharged away by 8 drain at last.
Specifically, 4 dust collection box parts, 2 supply the tuber pipe to adopt the diameter to be 19mm steel pipe welding, 1 venturi tube adopts and adopts the one-time tensile preparation shaping of 1mm thick steel plate, and the microcephaly diameter is 50mm, and the major part diameter is 110mm, and length is 130mm, and input and air flue connection, output and 7 dust removal case connection. 3 the safety cover is welded by 5mm steel sheet, with diameter 12mm round steel welded fastening in circular 3 safety covers between six venturi tubes, prevents that the coal cinder from pounding badly, and 3 safety cover overall dimension do: a cylinder of diameter 400mm and length 300 mm.
Specifically, 7 dust removal case parts adopt 5mm steel sheet welding to become 600mm 500mm (length x width x height) box, install twice dustproof 6 filter screens in the box, install a dust removal spraying in the front 50mm department of 6 filter screens of each, the interval is 300mm between the filter screen, install 9 buckled plates in 7 dust removal case wind current end departments, stop the deposit with water smoke. One 8 sewage outlets are arranged at the tail end of the box body and are arranged by a KJ25 type quick straight-through connector.
