Description

Tunnel Engineering cement fineness negative pressure screen analysis device
Technical field:
It the utility model is related to a kind of Tunnel Engineering cement fineness negative pressure screen analysis device.
Background technology:
For current screen analysis device in screening, screenings enters cyclone cylinder together with large quantity of air, is not collected by cyclone cylinder Dust laden air enters dust catcher, still compares aperture of filter screen containing part particle diameter in the air discharged after by dust catcher strainer filtering Also small ultrafine dust, the dust of this ultra-fine grain diameter is more more harmful to human body than the dust of big particle diameter in dust pollution, bears Pressure sieve is general to be all positioned over indoor use, and dust catcher directly discharges useless wind indoors, the analysis room higher to purity requirements Secondary pollution is caused in itself with operator.
Negative pressure is sieved and typically uses 0.080mm screen clothes, and screenings particle is smaller, it is easy to is blocked dust catcher screen pack, is needed Often dust catcher filter screen is cleared up, to meet the requirement of negative pressure sieve negative pressure, dust-collecting bag for dust collector and cyclone cylinder next part ash Bottle storage collected ash be all the very low powder of water content, easily flown upward in scale removal process, have to equipment and personnel compared with Big pollution, so that someone feels clean convenient not as good as water sieve using negative pressure sieve analysis.
Utility model content:
The purpose of this utility model is to provide a kind of Tunnel Engineering cement fineness negative pressure screen analysis device.
Above-mentioned purpose is realized by following technical scheme:
A kind of Tunnel Engineering cement fineness negative pressure screen analysis device, its composition include:Lower shoe, described lower shoe with it is upper Bottom plate is fixedly connected by one group of branch pipe, and analysis sieve is provided with described upper plate, and described analysis sieve passes through with cyclone cylinder Sweep-up pipe is connected, and described cyclone cylinder is fixedly connected with dust jar, and described dust jar is fixed on described upper plate, described Lower shoe on water tank is installed, water pump is installed, the upper end of described water pump and described dust jar leads on described water tank Water inlet pipe connection is crossed, the upper end of described cyclone cylinder is connected with drifting dust machine by dust outlet tube, and described drifting dust machine is fixed on described Lower shoe on, described drifting dust machine is fixedly connected with blow-off pipe, and the lower end of described dust jar passes through with described blow-off pipe Discharging tube connects.
Described Tunnel Engineering cement fineness negative pressure screen analysis device, leakage board is installed in described dust jar, it is described Leakage board on there is one group of leaking hole, the lower end of described cyclone cylinder is located at the lower end of described leakage board.
Described Tunnel Engineering cement fineness negative pressure screen analysis device, the lower end of described analysis sieve is fixed with vacuum table to be connected Connect, described vacuum table is fixedly connected with one end of negative pressure measurement pipe, the other end of described negative pressure measurement pipe and described suction Dirt pipe is fixedly connected.
Beneficial effect:
1. provided by the utility model is a kind of Tunnel Engineering cement fineness negative pressure screen analysis device, cyclone cylinder and drifting dust machine Connected by dust outlet tube, the end set of blow-off pipe instead of dust catcher, dust directly is discharged into outdoor, prevent in outdoor Secondary pollution.
The utility model uses leakage board, and the water pumped by water pump can be entered by the leaking hole on leakage board In dust jar, it can be flowed into blow-off pipe and be discharged in outdoor by discharging tube with mix dust, dust jar need not be frequent Cleared up, save the substantial amounts of time, also prevent pollution caused by cleaning dust jar.
The utility model can open water pump when not enabling, to being cleared up in dust jar, it is not necessary to and it is artificial to carry out, It is time saving and energy saving.
The end of blow-off pipe of the present utility model is in certain inclination angle, can prevent the rainwater of outside from pouring in down a chimney into blow-off pipe In, prevent from having an impact device.
Brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the sectional view in A portions of the present utility model.
