Description

A kind of negative pressure screen analyzer
Technical field
The utility model is related to cement fineness and examines equipment, more specifically, it relates to a kind of negative pressure screen analyzer.
Background technology
Negative pressure screen analyzer presses national standard T0501-94《The u m of the cement fineness method of inspection 80 sieve sieve formula》Carry out screen analysis The instrumentation of inspection.This product have it is simple in construction, it is easy to operate, be cement plant the features such as reduction energy consumption, building constructor with And possess the indispensable instrument of scientific research institutions and universities and colleges of cement specialty.
When dynamic medium of the negative pressure screen analyzer by the use of air-flow as screening works, whole system keeps negative pressure state, screen cloth In smart powder material to be measured be in fluidised form shape under the airflow function that the air nozzle of rotation sprays, and moved with air-flow, its The fine grained that middle particle diameter is less than mesh size is pumped by air-flow drive by screen cloth, and particle diameter is more than the coarse granule of sieve screen apertures then Stay in screen cloth to reach the purpose of screening.
The popular configuration of current negative pressure screen analyzer is more using vertical type high-power dust catcher as the negative pressure source of the instrument, and with small Type cyclone cylinder is used as pre-dedusting device.During screening, screenings enters cyclone cylinder together with large quantity of air, not by containing that cyclone cylinder is collected Dirt air enters dust catcher.In the air discharged after by dust catcher strainer filtering still containing part particle diameter than aperture of filter screen 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.Negative pressure Screen analyzer is typically all placed and used indoors, and dust catcher is directly discharged useless wind indoors, to analysis room and behaviour by exhaust outlet Author causes secondary pollution in itself.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of negative pressure screen analyzer, powder is prevented Dirt is got into the air by the emission by exhaust pipe of dust catcher.
Above-mentioned technical purpose of the present utility model technical scheme is that:A kind of negative pressure screen analyzer, Including analysis sieve, cyclone cylinder and dust catcher, the bottom of the analysis sieve is connected by being provided with hard tube with the upper end of cyclone cylinder, The top end opening of the cyclone cylinder is by being provided with soft pipe connection to dust catcher, and the dust catcher is provided with blast pipe, the row Tracheae side wall is connected with shower, and the shower is connected by being provided with least one shower nozzle with blast pipe, the blast pipe It is provided with check valve.
By using above-mentioned technical proposal, in the side wall connection shower of blast pipe, shower passes through shower nozzle and blast pipe Connection, shower carries out spray dust to the gas containing dust come out from dust catcher by emission by exhaust pipe, so that effectively Ground has purified the gas from emission by exhaust pipe air inlet, and dust is then integrated with water and to form muddy water from blast pipe discharge, it is to avoid Dust is discharged into air with gas and polluted;Check valve is set in blast pipe again, to avoid spray into blast pipe Water is flowed into dust catcher.
The utility model is further arranged to:Also include tank, the tank is connected by being provided with water pump To shower.
By using above-mentioned technical proposal, tank is set and spray-water is provided by water pump for shower, it is to avoid The trouble at external water source.
The utility model is further arranged to:The shower nozzle uses atomizer.
By using above-mentioned technical proposal, shower nozzle is used into atomizer, because the spray of atomization is more suitable for depositing dust, made More preferable dust-laying effect must be reached.
The utility model is further arranged to:The cyclone cylinder is provided between the air flow inlet and air stream outlet of upper end Sieve plate, the sieve aperture of the sieve plate is less than analysis and sieved.
By using above-mentioned technical proposal, a score is installed between the air flow inlet and air stream outlet of cyclone cylinder upper end The small sieve plate of the sieve aperture of sieve is analysed, so that further reducing dust enters dust catcher, which reduces discharged from blast pipe Dust Capacity.
The utility model is further arranged to:The flexible pipe outlet of the dust catcher is arranged with dust-separation bag.
By using above-mentioned technical proposal, dust-separation bag is set, to the gas entered inside dust catcher from flexible pipe, enters to advance The filtering of one step.
The utility model is further arranged to:The hard tube is connected with vacuum table.
By using above-mentioned technical proposal, vacuum table is set, when negative pressure does not reach standard, so that operating personnel can be fast Speed is observed, so as to make corresponding measure.
The utility model is further arranged to:The tank is provided with audible-visual annunciator, the tank and set It is equipped with the water level switch for controlling audible-visual annunciator.
By using above-mentioned technical proposal, audible-visual annunciator is set, and installs to control acousto-optic report in tank The water level switch of alert device, when water level is too low in tank, then water level switch will control audible-visual annunciator to send alarm signal Number, remind operating personnel's addition water.
In summary, the utility model has the advantages that:
First, in the side wall connection shower of blast pipe, shower is connected by shower nozzle with blast pipe, shower is to from suction The gas containing dust that dirt device is come out by emission by exhaust pipe carries out spray dust, so as to effectively purify from blast pipe row The gas of air inlet is put, while check valve is set in blast pipe, to avoid the water sprayed into blast pipe from flowing into dust catcher;
Second, installing the small sieve of a sieve aperture than analysis sieve between the air flow inlet and air stream outlet of cyclone cylinder upper end Plate, and dust-separation bag is arranged in the outlet of flexible pipe, so as to further be filtered to gas, to reduce the powder into dust catcher Dirt.
