Abstract
The utility model discloses a centrifugal dust separator, which belongs to the dedusting equipment field and comprises a spiral casing, an exhaust duct is vertically arranged in the middle of the spiral casing, a rotating flow passage which is spirally descended from outside to inside is formed between the exhaust pipe and the spiral casing, a feed inlet which is tangentially arranged on the outer wall of the spiral casing is accessed with the rotating flow passage, the lower end of the spiral casing is connected with a conical sedimentation cylinder whose upper portion is big and lower portion is small, the upper end of the inner cavity of the sedimentation cylinder is connected with the rotating flow passage, and the lower end of the inner cavity of the sedimentation cylinder is connected with a discharge hole, and the inner wall of the spiral casing is provided with a plurality of convex reinforcements which raised to the center of the spiral casing. When in work, air current gets into from the feed inlet with dust, and the convex reinforcements can prevent air current flow flowing, and particles which are blocked to collided on the convex reinforcements continuously go forward, and particles are more easily to be settled, only a little amount of very slight dust gets into a cloth bag from the exhaust duct, the settling speed of dust is fast, and the efficiency is high, and the yield of a pulverizer can be improved. The centrifugal dust separator can be used to collect disintegrated products when grain and feed stuff are disintegrated, and can be applied in other work places which need to dedusting.
Description
Technical field
The utility model relates to a kind of cleaner, particularly a kind of cyclone dust collectors.
Background technology
In the prior art, a kind of cyclone dust collectors are arranged, have another name called Asta-3746, it mainly comprises spiral case, and the spiral case center uprightly is provided with exhaust duct, forms the eddy channel that descends in the shape of a spiral from outside to inside between exhaust duct and the spiral case inwall, tangentially be provided with charging aperture on the spiral case outer wall and connect described eddy channel, the spiral case lower end is connected with the settlement barrel of up big and down small taper, and the inner chamber upper end of settlement barrel links to each other with described eddy channel, and settlement barrel inner chamber lower end is connected with discharging opening; The inner wall smooth of its spiral case.When work, charging aperture links to each other with the pulverizing chamber of pulverizer, the exhaust duct upper end connects a cloth bag, during pulverizer work, material after crushed is blown in the eddy channel under blast, attached on the spiral case inwall, and constantly to the discharging opening sedimentation, particle diameter is less in addition, the dust of lighter weight enters the sack cleaner from exhaust duct under blast drives under centrifugal action for the particle that wherein most of particle diameter is big, quality is heavier.This device can be used for the pulverizing processing of grain, feed, need higher wind speed and blast during pulverizer work, but excessive wind speed and blast (especially wind speed) has hindered the effect of settling of dust granules in cyclone dust collectors; A large amount of dust and sedimentation just enter in the cloth bag, easily stop up cloth bag, increase the live load of cloth bag, weaken it and cross wind energy power; And the mistake wind energy power of cloth bag descends, and can have a strong impact on the output of pulverizer; All the time, the effect of settling of cyclone dust collectors is not very good, sometimes often improve in order to improve effect of settling by the method that strengthens plant bulk, after strengthening, size can produce a series of unfavorable factors, as consumptive material increase, space requirement increase, blast decline, air quantity increase in demand, power of fan increase in demand etc.
The utility model content
The purpose of this utility model provides a kind of cyclone dust collectors, makes its effect of settling better, can improve the output of pulverizer.
The purpose of this utility model is achieved in that a kind of cyclone dust collectors, comprise spiral case, the spiral case center uprightly is provided with exhaust duct, form the eddy channel that descends in the shape of a spiral from outside to inside between exhaust duct and the spiral case inwall, tangentially be provided with charging aperture on the spiral case outer wall and connect described eddy channel, the spiral case lower end is connected with the settlement barrel of up big and down small taper, and the inner chamber upper end of settlement barrel links to each other with described eddy channel, and settlement barrel inner chamber lower end is connected with discharging opening; Described spiral case inwall is provided with some convex tendons to the spiral case central protuberance.
During the utility model work, charging aperture connects the discharging mechanism of pulverizer, exhaust duct connects a cloth bag, during pulverizer work, material after crushed is blown in the eddy channel under blast, wherein particle diameter is less, the dust of lighter weight under blast drives from exhaust duct separating device, the part particle diameter is bigger in addition, the heavier particle of quality under centrifugal action attached on the spiral case inwall, air-flow is subjected to the pressure beam of spiral case inwall and settlement barrel inwall, rotatablely move along spiral case inwall and the generation of settlement barrel inwall, in rotary movement, the continuous sedimentation of dust granules in the air-flow, final settlement is to discharging opening, and can have only the special calomel mercurous chloride dirt of sub-fraction to be delivered to sack cleaner by suction from the discharging opening separating device.Want to make dust granules sedimentation rapidly, key is the kinetic energy that will consume air-flow and dust granules, according to uncle captive's power principle, increase the frictional resistance of spiral case inwall, strengthen quick air-flow in Yan Bi rotatablely moves along the journey energy loss, consume air-flow and dust granules kinetic energy, thereby make air-flow stall, convex tendon also can play the dust granules in the quick air-flow simultaneously and directly block decelerating effect.The utility model is provided with convex tendon on the spiral case inwall, but convex tendon barrier air motion, simultaneously can block the particle that strikes on the convex tendon moves on, make it easier sedimentation, the sinking speed of dust granules is fast, efficient is high, can improve the output of pulverizer, the utility model can be used in the pulverizing of grain, feed the collection of crushed products also be can be used for the workplace that other need dedusting.
Described convex tendon can uprightly be provided with, and can be beneficial to the sedimentation of dust granules more, and can avoid dust to accumulate on convex tendon.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the utility model three-dimensional structure diagram.
Wherein, 1 exhaust duct, 2 convex tendons, 3 spiral cases, 4 settlement barrels, 5 discharging openings, 6 charging apertures.
The specific embodiment
As Fig. 1-3, be cyclone dust collectors, mainly comprise spiral case 3, exhaust duct 1 and settlement barrel 4, exhaust duct 1 uprightly is provided with at spiral case 3 centers, forms the eddy channel that descends in the shape of a spiral from outside to inside between exhaust duct 1 and spiral case 3 inwalls, tangentially is provided with charging aperture 6 on spiral case 3 outer walls and connects described eddy channel, the taper that settlement barrel 4 is big up and small down, settlement barrel 4 is connected spiral case 3 lower ends, and the inner chamber upper end of settlement barrel 4 links to each other with described eddy channel, and the inner chamber lower end of settlement barrel 4 is connected with discharging opening 5; Spiral case 3 inwalls are provided with some convex tendons 2 to the spiral case central protuberance, and described convex tendon 2 uprightly is provided with.
The utility model is not limited to the foregoing description, and convex tendon 2 also can be obliquely installed along the spiral case inwall, and convex tendon can be provided with from top to bottom continuously, and also space set is arranged to netted; In addition, in settlement barrel, also convex tendon can be set.
