Description
Technical field
The utility model relates to a kind of unloading valve, relates in particular to a kind of spiral unloading valve, belongs to sealed valve and discharge apparatus field.
Background technology
At present unloading valve has a wide range of applications in industrial enterprises such as environmental protection, metallurgy, chemical industry, grain, food, chemistry, and unloading valve can be carried conveying with various dust, also Packed effect simultaneously to granular material or granule materials.General star-like unloading valve of installation or flap valve are controlled ash discharge at the ash hole place, and all there is gas leakage in these two kinds of valves, because the cinder-discharging port place can produce certain negative pressure, make to be easy to occur reentrainment of dust.At material more and also occur easily when granule materials is arranged stuck, damage equipment.These two kinds of valves can leak air too, stuck and for the second time phenomenon of airborne dust, contaminated environment easily even load onto simultaneously on ash hole.
The Chinese patent Granted publication number is: CN2206271Y, the day for announcing is: the utility model patent in August 30 nineteen ninety-five discloses a kind of from close spiral dust unloadnig apparatus, be the equipment that is used for environmental protection dust exhaustor and dust feed bin ash discharge discharge, it is included in the lower end installing conveyor screw of cinder-discharging port hopper, transmission shaft is housed in the delivery pipe, between conveyor screw and motor, sealing arrangement is arranged, transmission shaft passes sealing arrangement and is connected on the motor shaft, on the other end of delivery pipe, rear side housing is installed, the shrimp shape pipe of discharging is housed on rear side housing, and flexible pipe is equipped with in the lower end of shrimp shape pipe.But the sealing property instability of this structure, the one, the self sealss weak effect, the discharging opening and the distance between the inlet point of delivery pipe are extremely short, helicallobe is difficult to realize sealing between the two, when the material that unloads feed bin when inlet point top is unstowed, helicallobe between discharging opening and the inlet point and the delivery pipe matching part gap that can leak air, the 2nd, the sealing effectiveness of flexible pipe is relatively poor and fragile, cause secondary dust phenomenon easily, and the screw shaft of conveyor screw is cantilevered single-point supporting construction, the moment of flexure of bearing at the discharge end screw shaft is bigger, and screw shaft easily produces off-centre, causes the wearing and tearing aggravation between helicallobe and delivery pipe inwall, gap increase, the self sealss performance descends, and reduce service life, makes manufacturing cost and accuracy requirement height.
Summary of the invention
The purpose of this utility model is to leak air easily when unloading ash and the defective and the deficiency of dust raising phenomenon for the second time at existing unloading valve, provides a kind of simple in structure, and productive costs is low, and self sealss are good, the spiral unloading valve of long service life.
For achieving the above object, technical solution of the present utility model is: a kind of spiral unloading valve, comprise motor, reductor, inlet point, discharging opening, helicallobe, sharf and transport tube, the output shaft of motor is connected with sharf through reductor, is fixed with helicallobe on the sharf, and the top of described transport tube one end offers inlet point, the bottom of the transport tube other end offers discharging opening, is provided with the seal section of length more than or equal to 0.5 helicallobe pitch between the inlet point of transport tube and discharging opening.
The length of described seal section is the pitch of 0.5-1 helicallobe.
The internal diameter of described transport tube is greater than 1 millimeter-2 millimeters of the diameters of helicallobe.
The two ends of described transport tube are provided with end cap, and the center of described end cap all is equipped with bearing seat, and the two ends of described sharf are installed in respectively on the bearing seat at two ends of transport tube.
One end of described sharf is connected with speed reducer output shaft, and the output shaft of described reductor and input shaft are on same axis, and the input shaft of reductor is connected with the output shaft of motor.
One end of described sharf is connected with speed reducer output shaft, and the input shaft of described reductor parallels with sharf, and the input shaft of reductor is connected with the output shaft of motor, and described motor is fixed on the outer round surface of transport tube.
One end of described sharf is through gear pair or sprocket wheel chain pair or pulley belt is secondary is connected with speed reducer output shaft.
The beneficial effects of the utility model are:
1, the utility model has been installed sharf and helicallobe in the axle center of cylindrical delivery tube, rotate the conveying that to finish granular material or granule materials by the driven by motor helicallobe, material can enter from the upper end inlet point of transport tube one side, export from the lower end discharging opening of transport tube opposite side again, because the transverse distance of inlet point and discharging opening is longer, material in the transport tube can form self sealss section preferably, can prevent effectively that gas leak phenomenon from taking place.
2, seal section length of the present utility model is the pitch of 0.5-1 helicallobe, self sealss are effective, the diameter of helicallobe is slightly less than the internal diameter of transport tube, there are not wearing and tearing, gap between helicallobe and transport tube inwall is less, and be easy to adhere to dust on the inwall of transport tube, can further dwindle the gap between helicallobe and the transport tube inwall, to improve self-packing air-tightness, even the material that unload in the feed bin inlet point top is unstowed, material in the seal section still gets lodged between inlet point and the discharging opening, still can make transport tube remain on the self sealss state, add that the gap between helicallobe and transport tube inwall is less, stick to dust on the inwall of transport tube and can get lodged in and form sealing between the gap, thus can not leak air and the second time airborne dust phenomenon.
3, the utility model compact conformation, easily manufactured, the transport efficiency height, because the material in the transport tube is axially to carry along helicallobe 5, even the particle of material is big or have foreign matter, can not produce valve plate stuck phenomenon as star-like unloading valve yet. not only be suitable for the discharging of granular material, also be suitable for the conveying of granular material, the frequency of operation by regulating unloading valve and the time gap of running simultaneously, can apply to extensively that dust in the environmental protection dedusting is carried and the ash discharge discharge operation of feed bin in.
