Abstract
The utility model discloses a dust collector in a tunnel, which relates to an air purifying device used for the construction site of the tunnel. The dust collector in a tunnel is composed of a filter box, a draught fan, a filter tube array, and a reverse spraying mechanism. After the air is filtered by a coarse filter plate, the draught fan can make the air which needs to be purified introduced to the filter box from the inlet of the filter box; after the air is filtered by the filter tube array which is arranged in the filter box, the air can be discharged, and the dust in the air can be retained on the external wall of the filter tube. Through the reverse spraying mechanism, after the high-pressure air is sprayed and blown into the filter tube through the reverse spraying mechanism, the dust which is retained on the external wall of the filter tube can be shaken into a dust collecting chamber on the bottom part of the filter box. The utility model which has the advantages of less occupation of land, large treated air quantity, and high dust-collecting efficiency is especially suitable for the air purifying device which is used for the construction site of the tunnel, or the mining operation surface of the coal.
Description
The utility model relates to a kind of air cleaning unit that is applicable to constructing tunnel scene or colliery digging operation face.
In the excavation explosion in tunnel with spray in the lining construction process or all have a large amount of dust to produce in the mining process of colliery, these dust not only are harmful to the operation of construction equipment, the progress and the quality of influence construction, even more serious is, a large amount of dust will endanger the healthy of constructor, the possibility that makes the personnel that are engaged in this class operation for a long time suffer from anthraco-silicosis increases greatly, in the prior art, still there is not the effectively air cleaning unit of these dust of filtering.
The purpose of this utility model promptly is a kind of air cleaning unit that is exclusively used in filtering constructing tunnel scene or the airborne dust of colliery digging operation face of design.
To achieve these goals, the utility model is arranged a chimney filter battle array in a long and narrow Rose Box, adopt centrifugal fan that dust-collecting air to be clean is introduced after coarse filtration in the Rose Box and through the chimney filter battle array by the Rose Box inlet and filter the back discharge, be trapped in dust on the chimney filter outer wall then by regurgitating in the dust storage chamber at the bottom of pressure-air makes it to expect to drop on Rose Box.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model tunnel precipitron.
Accompanying drawing 1,2 is respectively the elevation and the right view of the utility model tunnel precipitron.
With reference to the accompanying drawings 1 and accompanying drawing 2, the utility model tunnel precipitron is mainly by Rose Box, blower fan, chimney filter battle array with regurgitate mechanism and form.Rose Box 1 is narrow cuboid, the sealing of one end, the other end is air intlet and draw and insert-type coarse filtration plate 2 is installed, the Rose Box both sides have chamber door 3 to be opened/closed, the Rose Box bottom is a dust storage chamber 4, the both sides of dust storage chamber have dedusting door 5 to be opened/closed, have the dividing plate 6 that is used to hang chimney filter and Rose Box is divided into the upper and lower in the Rose Box.Blower fan 7 is a centrifugal fan, is installed in the top of Rose Box and is driven by motor 8, and its intake is communicated with Rose Box top, and dissipative muffler 9 is equipped with in its outlet.The chimney filter battle array comprises a plurality of chimney filters that are ordered in the Rose Box bottom, chimney filter 10 is a tubular, is made by felt, hangs on the Rose Box internal partition 6 by its upper end, the upper end of chimney filter is opening and is communicated with Rose Box top, the spring 11 that is used to support chimney filter is housed in the chimney filter.Regurgitate the main jet pipe 12 that mechanism comprises that radical equates with chimney filter columns in the Rose Box, one end of every main jet pipe all has a compressed air valve, prop up jet pipe 13 along what main jet length of tube direction was evenly distributed with that radical and chimney filter row number equates, each jet pipe is in chimney filter all chimney filters that stretch into same column respectively suitable for reading.
When the tunnel precipitron was worked, blower fan was introduced Rose Box by the Rose Box inlet with air to be clean after coarse filtration plate coarse filtration, discharged after the chimney filter battle array in being arranged in Rose Box is filtered again, and airborne dust then is trapped on the chimney filter outer wall.By the anti-nozzle pressure-air of in chimney filter, jetting the dust that is trapped on the chimney filter outer wall is shaken off in the dust storage chamber of Rose Box bottom, and be removed by the dedusting door.
The utility model takes up an area of less, the processing air quantity is big, dust catching efficiency is high, so be particularly suitable for the air cleaning unit as constructing tunnel scene or coal mining face.
