Abstract
This utility model discloses an adjustable air discharging dust remover which belongs to tower dryer dust remover field, which includes a fen connected with the falling dust room interface of main tower. The air discharging port of fan is connected with the guiding object with the guiding blade inside. The upper position of guiding object is positioned with spiral case. The spiral case includes the axial direction inlet connected with guiding object under the spiral case and the axial direction outlet connected with guiding object on the spiral case. The axial direction inlet is directly connected with the axial direction outlet. The flank side between the axial direction inlet and axial direction outlet is spiral case passage. The spiral case passage is extended in spiral from inside to outside. One end of bypass is connected with the outlet of the spiral case passage. The other end stretches into the upper position of vertical dust collecting chamber. The dust collecting chamber is equipped with the adjustable wind door. This utility model is featured with the advantages of better dust removal effect and adjustable wind door. It is applicable to apply in the various grain and feed production which needs the dust removal process.
Description
Technical field
The utility model relates to a kind of grain and oil plant processing equipment, particularly is used for the tower dryer dust arrester.
Background technology
The exhaust emission system that is used for tower dryer at present has two kinds of forms.A kind of form is that waste gas is directly entered atmosphere by the tower exhaust outlet; Also having a kind of is that expansion chamber is set, and blower fan links to each other with falling dust room's interface of king-tower, can will enter atmosphere again after big assorted separation the in the waste gas.The form of expansion chamber has and adopts and the body of the tower one, also has to separate with tower and adopt the space that links to each other with factory building.Such gas extraction system exists many problems, for example is accompanied by the oven dry production of dryer, and oven dry waste gas constantly enters atmosphere, and a large amount of scurfs that are mingled with in the waste gas, clever shell, grit etc. enter atmosphere thereupon continuously, severe contamination environment.
Because the initial aqueous rate difference of every batch of oven dry raw grain, the oven dry job parameter of dryer such as intake, temperature, row's grain speed etc. are provided with just inequality, need to regulate.And the adjusting of air quantity, for the tower dryer that adopts axial flow blower, normally control moves the quantity of blower fan.Because existing air exhauster is not provided with damper, therefore when the oven dry of dryer is produced, if the blower fan that has is work not, like this under running blower fan drives, the blower fan of not working produce backward rotation not only because of so cause wearing and tearing, and cause path short circuit to have a strong impact on the effect of oven dry.
For the tower dryer of present utilization, especially large-scale dryer mostly disposes large fan, and running noises is bigger, has a strong impact on environment.Particularly be installed near the residential block or the city, can't reach environmental requirement, have a strong impact on resident's life.Since these technical problems, the development and the range of application that have greatly hindered tower dryer.
At present, many oily factories, grain and feed-processing plant are positioned at city or suburb mostly, and environmental requirement is all very high, if the tower dryer dust removal problem does not solve, these factories just can't adopt.
The utility model content
The utility model project purpose is exactly at tower dryer exhaust emission system above shortcomings, development structure compactness, working (machining) efficiency height, noise reduction, good dedusting effect, adjustable exhausting-dusting device of energy savings.
For achieving the above object, the utility model provides a kind of adjustable exhausting-dusting device, it comprises the blower fan that links to each other with falling dust room's interface of king-tower, the air outlet upper shaft of described blower fan is to the cylindrical shape baffle that is connected with upright setting, be provided with guide vane in the baffle, the baffle top is connected with spiral case, described spiral case comprises axial inlet that is connected with baffle that is arranged on the spiral case below and the axial outlet that is arranged on the spiral case top, axial inlet and axially outlet directly connection vertically, side between axial inlet and the axial outlet is snail plume road, snail plume road outwards extends spirally from the inboard, leading to adapter one end on one side links to each other with the outlet in snail plume road, the other end of bypass connecting pipe stretches into a upright dust storage chamber top that is provided with, and is provided with in the dust storage chamber from its top to the bypass escape pipe of edgewise bend; Axially the outlet top is connected with muffler, and the muffler top is provided with the adjustable air door of aperture.
During the utility model work, the assorted waste gas that contains in the king-tower falling dust room is crossed baffle by blower fan negative pressure drag flow, waste gas forms the air-flow that moves along in the body wall rotation under the guide vane effect in baffle, when air-flow process spiral case, because being separated by spiral case, the effect of rotary centrifugal force, wherein clever shell, scurf and grit enter dust storage chamber; All the other clean waste gas upper reaches enter atmosphere by damper after reducing noise through muffler, this installs many sets in parallel operation, when air quantity is regulated in oven dry, owing to need to reduce the quantity of operation blower fan, will close down blower fan, at this moment, the damper of the blower fan that stopped can cut out, thus the path of partition atmosphere and king-tower falling dust room, avoid blower fan counter-rotating and from the reverse air inlet of air outlet, reduce wear, using electricity wisely reduces consuming.The utility model can be applicable to the place that needs dedusting in the plurality of cereals production of fodder.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model project;
Among the figure: 1 blower fan, 2 guide vanes, 3 baffles, 4 spiral cases, 5 mufflers, 6 air doors, 7 bypass connecting pipe, 8 dust storage chambers, 9 bypass escape pipes.
The specific embodiment
As figure, be the exhausting-dusting device, it comprises the blower fan 1 that links to each other with falling dust room's interface of king-tower, blower fan 1 adopts big flow, the blower fan of high blast, the air outlet upper shaft of blower fan 1 is to the cylindrical shape baffle 3 that is connected with upright setting, be provided with guide vane 2 in the baffle 3, after gas flows through guide vane 2, form the gas of eddy flow, make the trifle in the world centrifugal motion and be close to baffle 3 inwalls and advance, baffle 3 tops are connected with spiral case 4, described spiral case 4 comprises axial inlet that is connected with baffle 3 that is arranged on spiral case 4 belows and the axial outlet that is arranged on spiral case 4 tops, axial inlet and axially outlet directly connection vertically, side between axial inlet and the axial outlet is snail plume road, and snail plume road outwards extends spirally from the inboard, leads to adapter 7 one ends on one side and links to each other with the outlet in snail plume road, the other end of bypass connecting pipe 7 stretches into upright dust storage chamber 8 tops that are provided with, and is provided with in the dust storage chamber 8 from its top to the bypass escape pipe 9 of edgewise bend; Axially the outlet top is connected with muffler 5, and muffler 5 tops are provided with the adjustable air door of aperture 6, and this air door both can be designed to manual, also can be designed to electronic; When air-flow process spiral case, because the effect of rotary centrifugal force, wherein clever shell, scurf and grit are separated by spiral case and enter dust storage chamber 8, and a small amount of gas flows out from bypass escape pipe 9, a large amount of clean gas through the axial inlet of spiral cases, axially go out muffler and air door and discharge.
The utlity model has the performance of air quantity adjusting, dedusting, noise reduction; Energy savings, saving material consumption, the trifle in the world recycling; Compact conformation, easy to manufacture, processing cost is low; Can thoroughly solve the pollution difficult problem that tower dryer enters city factory.
