Abstract
The utility model discloses a jet mill dust-removal bag filter, which comprises a bag filter and a baffle, wherein the baffle is arranged inside the bag filter close to a feed port of the bag filter. After the baffle is additionally arranged, a corresponding pre-sedimentation chamber is formed between the baffle and the bag filter, so that the impact of materials and hot air on the filter bag is effectively reduced, the number of maintenance of equipment is greatly reduced, and the maintenance cost is reduced, and the manpower is saved; most of the materials are sedimented in the pre-sedimentation chamber, so that the load on the filter bag is reduced, the yield of the bag filter is increased, and the labor efficiency is improved; and meanwhile, the environmental protection is facilitated.
Description
Technical field
The utility model relates to a kind of dust filtering device, in particular a kind of air-flow is pulverized the dust settling pocket filter.
Background technology
Bag hose is applied to the titanium white production post processing vapour powder stage, mainly adopts action of low-voltage pulse locellus winding-up dedusting, filter area 600m
2, filtration velocity 0.7-0.8m/min handles air quantity 25000-28800m
3/ h, operation pressure drop 350-450mmH
2O, inlet temperature 200-260 ℃, the cloth bag keel frame of outfit stainless steel.During bag hose, 230 ℃ of operating temperatures can be born transient temperature and can be reached 260 ℃.
The casing of bag hose also is a stainless steel, and the bottom of bag hose is provided with discharge with endless screw device and star-like discharge valve, and integral sealing is good.
But present this bag hose is because cloth bag often is subjected to the collision of material and hot blast, is easy to cause cloth bag to damage, and efficiency of dust collection is low, causes dust to overflow pollutant atmosphere.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of air-flow to pulverize the dust settling pocket filter, prolongs the cloth bag life-span by a baffle plate is set in bag hose, has increased the output capacity of bag hose, improves efficiency of dust collection.
Technical scheme: the utility model comprises bag hose and baffle plate, and described baffle plate is arranged at the charging aperture of the inner and close bag hose of bag hose.
For reaching better dust removing effects, the feedstock direction of described baffle plate and bag hose is perpendicular.
Described baffle plate is the stainless steel baffle plate, can increase the service life of baffle plate.
Beneficial effect: the utility model has the following advantages compared to existing technology, after the utility model has increased baffle plate, formed corresponding preliminary sedimentation chamber between baffle plate and the bag hose, reduced the impact of material and hot blast very effectively to filter bag, reduced equipment checking maintenance number of times greatly, reduce maintenance cost, saved manpower; Most of material has alleviated the load of bag hose in preliminary sedimentation chamber deposition, has increased the output capacity of bag hose, has improved production efficiency; Improved efficiency of dust collection simultaneously, very big facilitation has also been arranged aspect environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises bag hose 1 and stainless steel baffle plate 3, and baffle plate 3 is arranged at the charging aperture 2 of bag hose 1 inner and close bag hose 1, and the feedstock direction of baffle plate 3 and bag hose 1 is perpendicular, can reach better dust removing effects.Just formed the preliminary sedimentation chamber between baffle plate 3 and the bag hose 1, reduced the impact of material and hot blast very effectively filter bag.
The titanium dioxide material is after vapour powder machine is pulverized, deliver to the charging aperture 2 of bag hose 1, use air-introduced machine 4 exhausting in a side relative with charging aperture 2, make and produce negative pressure in the bag hose 1, hot blast and material directly impact on baffle plate 3, most of material directly falls owing to the gravity effect, leftover materials continue to flow in bag hose 1 with hot blast, hot blast can be discharged under the effect of air-introduced machine 4, and material is got off by the cloth bag filtration of bag hose 1, can make the dust rate of recovery reach 99.8%, uses baffle plate 3 effectively to have reduced to advance the impact to filter bag of material and hot blast, alleviate the load of bag hose, increased the output capacity of bag hose 1 effectively.Prolong the service life of filter bag, reduced maintenance frequency, reduced maintenance cost.
After using baffle plate 3, hot blast and titanium dioxide material enter bag hose 1 by charging aperture 2, directly impinge upon on the baffle plate 3, most of titanium dioxide granule (titanium dioxide) falls along with bump, and all the other are got off by the cloth bag filtration of bag hose 1, the bottom of bag hose 1 is provided with discharge with endless screw device 5 and feed bin, after material falls, enter discharge with endless screw device 5, enter feed bin through star-like discharge valve then, directly pack, be the rutile type titanium white finished product with finished bag.
Claims (3)
1. an air-flow is pulverized the dust settling pocket filter, it is characterized in that, comprises bag hose (1) and baffle plate (3), and described baffle plate (3) is arranged at the charging aperture (2) of the inner and close bag hose (1) of bag hose (1).
