Description
Technical field:
The utility model relates to dust exhaust apparatus, relate to more specifically a kind of in coal, metallurgy, water power, railway and city underground, constructing tunnel, produce during industrial production such as supporting spray concrete concrete work and pottery fly upward the dust exhaust apparatus that dust absorbs.
Background technology:
Concrete sprayer is because of jet performance is stable, rebound degree is little, production efficiency is high, convenient operating maintenance, by multiple industry extensive use, but the dust-producing amount of spraying operation own is very big, during simultaneously most operation with perforating, blow out, beat anchor pole, adorn the bigger operation parallel operations of product dirt such as cash, shipment, the quantity of producing dirt like this is just more, and the dust concentration in the operating environment can reach 200～500mg/m
3, exhale dirt can reach 80～100mg/m
3, and free SiO in the dust
2Content is up to 30～35%, and operating personnel's physical and mental health in serious threat.In order to address this problem, for many years, people have taked measures such as spraying, watering, wet feed, electric fan dedusting and individual protection to reduce dust pollution, obtained certain effect, but because have easy fouling, easily stop up, difficult cleaning, operation inconvenience, the high deficiency of maintenance operating cost, progressively stop or stopping using substantially.In addition, in ceramic industry was produced, fragmentation, grinding, screening, dry body repaired biscuit, glazing and loading of kiln also produced a large amount of dust that flies upward early stage, the contaminated environment air, and the direct labor is healthy in harm.Prior art adopts dry dust removal, with cyclone dust removal and bag-type dusting, but can only purify thick or in thick dust, and bag-type dusting is easily blocked, troublesome poeration, purification efficiency is low, weak effect.
Summary of the invention:
The purpose of this utility model is intended to overcome the deficiencies in the prior art part, provide a kind of less scaling and stop up, be easy to clear up, handled easily, the maintenance operating cost is low, efficiency of dust collection is high, the effective pneumatic dust exhaust apparatus of spray concrete equipment.
The purpose of this utility model can realize by following technical measures:
This dust exhaust apparatus is communicated with the dust shield tube connector at the dust shield that is connected with several vacuum generators, be provided with the water spray thrower at the dust shield tube connector or the outside that is located at the air inlet on the dust arrester, dust arrester is connected with discharge pipe, the dirt filtrating screen that connects discharge pipe is positioned at the dust arrester inboard, and the dust shield tube connector is connected or is communicated with air inlet with the dust arrester tube connector that is connected in dust arrester.
The purpose of this utility model also can realize by following technical measures:
The dust arrester inboard is connected with the baffle plate relative with air inlet; The mouth of pipe that the mouth of pipe of dust arrester tube connector and discharge pipe are connected with dirt filtrating screen is oppositely arranged; Dust shield is tubaeform.
The utility model utilizes " Wen Qiuli " operation principle to produce-92% negative pressure of vacuum around the dust shield mouth, the dust-contained airflow of production scene is sucked by dust shield, after going out dirt, the water smoke that spray thrower sprays enters disposal box during again by the dust shield tube connector, at first bump against with baffle plate, overwhelming majority dust granules freely falls, obtain buffering owing to after dust-contained airflow is in entering dust arrester simultaneously, the dust granules that part is not fallen as yet falls, at last, the air-flow that contains micronic dust is sent by discharge pipe after dirt filtrating screen filters.
The voltage supply air that contracts is a power beyond the vacuum generator of the present utility model, the water smoke amount of spray thrower ejection is adjusted to and can all sprays dust, dust shield tube connector and dust arrester tube connector can adopt screw thread, the company of gulping down or mode such as link flexibly connects, equally, dust shield tube connector and air inlet also can adopt modes such as screw thread, the company of gulping down to flexibly connect.After the dust in the dust arrester is full, dust arrester is separated easily with the dust shield tube connector, outwell dust.
