Background technology
Cyclone dust collectors are the centrifugal force that dusty gas produced that utilizes rotation, the gas-solid separator of a kind of dry type that dust is separated from air-flow.When dust-contained airflow gets into cyclone dust collectors by the inlet scoop, air-flow will become circular motion by rectilinear motion.Density contacts with wall greater than the grit of gas and just loses inertia force and fall along wall, gets into ash releasing tube.The outer rotational gas flow that rotation descends is when arriving cone, because of conical contraction is drawn close to the deduster center.When air-flow arrives a certain position, cone lower end, promptly with same direction of rotation from the cyclone dust collectors middle part, the shape of from bottom to top continuing to spin is flowed, final purification gas is outside the blast pipe displacer.
The cyclone dust collectors of prior art adopt the impeller feeding machine to lock wind and gather dust, and are as shown in Figure 1, comprise compositions such as blower fan 1, inlet scoop 2, air outlet 3, whirlwind tube 4, flue-dust retainer 5, lucite tube 6, impeller feeding machine 7 and ash releasing tube 8.After dust-contained airflow is got into by the inlet scoop; Air-flow will become circular motion by rectilinear motion; Density contacts with whirlwind tube 4 walls greater than the grit of gas and just loses inertia force and fall to arriving cone flue-dust retainer 5 along wall, and impeller feeding machine 7 absorbs grit in the ash releasing tube 8 as the air locking machine structure.Impeller feeding machine 7 for band lattice chamber rotary blade, body, and novel cycloidal-pin wheel decelerator etc. partly form; When impeller is rotated in body by the transmission mechanism driving; The powder grain material that top flue-dust retainer 5 falls just gets into impeller lattice chamber by charging aperture, and is sent to the discharge port discharge along with the rotation of impeller.The speed of impeller feeding machine 7 discharges must be greater than the speed of gathering dust of rotoclone collector flue-dust retainer 5, otherwise can cause the dust stratification of flue-dust retainer 5 cumulative and air channel that shape is risen is stopped up, and causes rotoclone collector to lose dust collection effect; Because when design, impeller feeding machine 7 discharge velocities were greater than control of dust speed, impeller feeding machine 7 can cause blade wear in use for some time and air leakage phenomena occur, when in a single day the airlock of negative pressure cyclone dust collection leaks out; It is outdoor with the air channel discharge just to have dust, causes reentrainment of dust, has not only wasted material; Also polluted simultaneously environment; When the airlock of rotoclone collector leaks out when reaching 15%, the effect of not gathering dust basically, promptly collected dust is all discharged outdoor with discharge pipe.The impeller feeding machine needs power to drive, and need during use and must often safeguard, its structure relative complex, the blade easy abrasion that works long hours, relative cost is higher.
The utility model content
The utility model is the shortcoming to above-mentioned existence, and existing rotoclone collector is improved, and its air locking machine structure is simple in structure, cost is low and easy to maintenance.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of rotoclone collector comprises whirlwind tube, flue-dust retainer, air locking machine structure, ash releasing tube, and the air locking machine structure is located between flue-dust retainer and the ash releasing tube, it is characterized in that the air locking machine structure is the soft cloth tube, and soft cloth tube upper end is located at below the flue-dust retainer, and soft cloth tube end is located in the ash releasing tube.Usually the soft cloth tube is made with the low cloth of gas permeability, and the soft cloth tube also can be formed with the cloth sheet of a slice or multi-disc, negative pressure on flue-dust retainer, occurs, negative-pressure sucking can occur between the cloth sheet.When rotoclone collector was started shooting, do not have material in the dust hopper this moment, and the soft cloth tube plays the lock wind action owing to the suction of negative pressure is bonded together; When in the dust hopper certain dust being arranged; Because the gravity of the quality of dust and the effect of lock wind, the soft cloth tube is because of losing suction and opened by the effect of dust gravity, and dust flow into the ash releasing tube through the soft cloth tube from flue-dust retainer; When flue-dust retainer dust gravity deficiency is locked wind to play; The soft cloth tube goes round and begins again with regard to the effect that receives negative-pressure sucking and bonding, thereby accomplishes the circulation again and again of lock wind ash discharge.
In the practical implementation, the soft cloth tube is terminal to be provided with a fixed connection point with the ash releasing tube inwall.What the soft cloth tube was terminal a bit is fixedly connected with the ash releasing tube inwall, in case negative-pressure air-flow is not drawn into flue-dust retainer to the soft cloth tube and causes ash discharge to stop up when flue-dust retainer has dust stratification.
In the practical implementation, flue-dust retainer connects lucite tube down, and soft cloth tube upper end is connected with lucite tube, and terminal a bit is connected with ash discharging hole.Lucite tube is mainly used in the convenient dust of observing and overstocks and the ash discharge situation.
In the practical implementation, be covered with the cloth cover between lucite tube and ash releasing tube, in case behind the dust that the soft cloth tube the is collected entering ash releasing tube, dust outwards flies upward.
The beneficial effect of the utility model is: the air locking machine structure of the utility model and traditional impeller feeding machine are relatively; Its advantage is less investment; Easy to make, safeguard simple, unpowered; To being applied on the dust collection device that needs negative pressure lock wind, discharge below the flue-dust retainer lower end diameter 60MM, its effect is better.
