Abstract
The invention discloses a spiral sand removing device. The device comprises a plurality of unit sand/dust separating devices; a sand/dust collecting chamber for collecting the separated sand/dust from the unit sand/dust separating devices is arranged under the unit sand/dust separating devices; the opening in the bottom of the sand/dust collecting chamber is provided with an automatic turnover plate, which can automatically turn over to open the opening; each unit sand/dust separating device comprises an air-intake flow-guide pipe and an air discharge pipe, wherein spiral flow-guide blades are arranged in the air-intake flow-guide pipe, one end of the air discharge pipe stretches into the air-intake flow-guide pipe; and an annular dust-removing gap is formed between the external wall of the air discharge pipe and the internal wall of the air-intake flow-guide pipe. The spiral sand removing device has the characteristics of simple structure, small volume, good dust separating and removing effect, and small wind resistance; after the assembly, the maintenance is not required, no other auxiliary machine such as suction fan is needed to discharge the sand/dust, and the device also has a certain function on draining rain water.
Description
Technical field
The present invention relates to a kind of dustproof filter equipment, relate in particular to a kind of device automatically will be separated with air containing the sand and dust in sand and dust air.
Background technology
What so-called wind-sand activity was exactly wind effect caused by the earth's surface of drying is a series of
physical phenomenon.Among the sand and dust fleet-footed runner air that normally particle is tiny, be in suspended state, be subject to the impact of the spatial movement of air simultaneously.
Chinese environmental detects the brainstrust of master station then using the concentration of suspended particulate substance in air as measurement index.During nearest Beijing Dust, suspended particulate matter concentration every cubic metre is generally no more than 1000 micrograms, and concentration during sandstorm will considerably beyond this index.
In air, sand and dust content is higher easily makes people suffer from dye respiratory tract and gastrointestinal disease, also can cause adverse influence to the normal operation of some equipment.
For the demand of anti-dust filtration in ventilating system, apparent, particularly very important in NORTHWEST CHINA portion, if the ventilating system occasion that sand and dust are larger only uses conventional intermediate effcient filter, can because of dustiness in air comparatively high-pass filter lost efficacy very soon, short a couple of days, that grows point need safeguard replacing a week.People have developed multiple deduster for this reason, conventional deduster form has at present: bag-type dusting, water film dedusting, cyclone dust removal, plasma dedusting etc., aforesaid way is all ripe and be used widely, but all there are some problems, than if any complex structure cost high, need frequent maintenance, some efficiency low power consumings are high.
Summary of the invention
For the problems referred to above, the invention provides one and have that structure is simple, cost is low, energy consumption is little, can the spiral sand cleaning machine of automatic sand discharging.
To achieve these goals, technical scheme of the present invention is as follows:
Spiral sand cleaning machine, it is characterized in that, comprise some groups of unit sand and dust separation devices, be provided with for collecting the sand and dust collecting chamber isolating sand and dust in unit sand and dust separation device in the below of unit sand and dust separation device, the bottom opening place of described sand and dust collecting chamber is provided with one can the self-action turnover panel opened of automatic turning;
Described unit sand and dust separation device comprises air intake mozzle and exhaust duct, spiral helicine guide vane is provided with in described air intake mozzle, one end of exhaust duct is stretched in air intake mozzle, and defines the dust discharge annular space of an annular between the inner tubal wall of the outer tube wall of exhaust duct and air intake mozzle.
In the present invention, one end of self-action turnover panel is provided with self gravitation by the counterweight of the other end of self-action turnover panel upwards pressing, and the other end is free end, and the position of the close counterweight of self-action turnover panel and the sidewall of sand and dust collecting chamber are rotatably connected.Further, described counterweight comprises an adjustment screw mandrel and is arranged on the weight on this adjustment screw mandrel.
In the present invention, the bottom opening of described sand and dust collecting chamber is tilting opening, and one end that itself and self-action turnover panel are rotatably connected is lower than the other end, and described counterweight is vertical with the plate face of self-action turnover panel.
In the present invention, described some groups of unit sand and dust separation devices are arranged in a casing, and sand and dust collecting chamber is arranged on the bottom of casing.
In the present invention, the other end of described exhaust duct is bell-mouth structure of air.
Operation principle is: first enter air intake mozzle containing sandy environment air, under the effect of guide vane, air produces and rotates, the air-flow Midst density particle larger than air relies on inertia force outwards to move to the upper of air intake mozzle because of centrifugal action, and separate from dust discharge annular space, enter sand and dust collecting chamber; Cleaned gas after separation is discharged from exhaust duct.The structure of this uniqueness can be arranged to multitube side by side, can meet the demand of different air quantity.
In order to ensure that enter sand and dust collecting chamber sand and dust is unlikely to again to be sucked exhaust duct by dust discharge annular space through separation, sand and dust collecting chamber is needed to keep opposing seal, its sealing is reached by self-action turnover panel and counterweight effect, when sand and dust collection accumulation gravity exceedes the active force of counterweight, self-action turnover panel is opened automatically, after sand and dust fall to discharging, under the effect of counterweight, self-action turnover panel automatically resets, sealing sand and dust collecting chamber, natural wind is prevented to be blown into, complete and once unload the husky cycle, go round and begin again work like this, realizes automatic sand discharging dirt.
Feature of the present invention has: the simple volume of structure is little, and be separated good dedusting effect, windage is little, and after once mounting, automatic sand discharging dirt is non-maintaining, do not need auxiliary blower fan sand discharge dirt of bleeding, and have certain for rainwater function.
The detailed description and obtaining that feature of the present invention can consult the graphic and following better embodiment of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the schematic diagram that the present invention collects sand and dust.
Fig. 3 is the schematic diagram of automatic sand discharging of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
See Fig. 1,2,3, spiral sand cleaning machine, comprises a casing 10, arranges some groups of unit sand and dust separation devices 20 in this casing, and the bottom of casing arranges sand and dust collecting chamber 30.
Unit sand and dust separation device 20 comprises air intake mozzle 21 and exhaust duct 22, is provided with spiral helicine guide vane 211 in air intake mozzle, so that produce spiral air flow.One end of exhaust duct 22 is stretched in air intake mozzle, and defines the dust discharge annular space 23 of an annular between the inner tubal wall of the outer tube wall of exhaust duct and air intake mozzle.The other end of exhaust duct is bell-mouth structure of air.
