Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
As shown in Figure 1, the guiding device of a kind of sack cleaner of the present invention, comprises ash bucket 2, casing 3, cloth bag 4 and n deflector 5.Ash bucket 2 is fixedly connected on the below of casing 3.The base plate of casing 3 is provided with n+1 row air vent 6.The base plate of casing 3 evenly lays multiple air vent 6, and air vent 6 is in array distribution.Cloth bag 4 is arranged in casing 3, and one end of cloth bag 4 is fixedly connected on the base plate of casing 3.The corresponding air vent 6 of each cloth bag 4, air vent 6 is communicated with ash bucket 2 and cloth bag 4.Deflector 5 is arranged in ash bucket 2, and deflector 5 is fixedly connected on the wall of ash bucket 2.Space is had between deflector 5 and casing 3 base plate.The wall of ash bucket 2 is provided with air inlet 1, and the plate face of deflector 5 is relative with air inlet 1.Gas approach axis in air inlet 1, deflector 5 is between two adjacent row air vents 6.N be more than or equal to 1 integer.
In the guiding device of said structure, deflector 5 is for shunt gas.After the gas diversed plate 5 first time shunting that air inlet 1 passes into, portion gas upwards flows along deflector 5, flow to the space between deflector 5 and casing 3 base plate.Space between each deflector 5 and casing 3 base plate communicates.Therefore, the gas flowing to the space between deflector 5 and casing 3 base plate, under the effect of respective pressure, can flow mutually, realizes second time shunting, then enters in cloth bag 4.After first time shunting and second time shunting, the speed of the gas passed into from air inlet 1 obviously declines, thus reduces the speed that air-flow enters casing, alleviates the impact of air-flow to cloth bag 4.After first time shunting, another part gas flows downward along deflector 5, is mingled with the ash particle that diversed plate 5 stops in this gas.After the diversed plate shunting of this portion gas, speed is significantly successively decreased, and arrives ash bucket 2 rear surface hourly velocity very little, is not enough to produce backflow.Therefore, this portion gas there will not be backflow in ash bucket 2.
Further, the angle between n described deflector 5 and casing 3 base plate, gas approach axis in air inlet 1, increases successively.From air inlet 1 more away from deflector 5, the angle between itself and casing 3 base plate is larger.Air-flow enters in ash bucket 2 by air inlet 1, and air-flow is jet, decrease of speed, so deflector 5 is arranged along air flow direction, and along with the reduction of air velocity, the angle between deflector 5 and casing 3 base plate increases according to this, and what make uniform stream enters each cloth bag.
As preferably, the angle between described deflector 5 and casing 3 base plate is 60 °-90 °.Angle 90 ° between air inlet 1 deflector 5 farthest and casing 3 base plate.Such as, the angle of four deflectors 5 in Fig. 1 is followed successively by 60 °, 70 °, 80 °, 90 °.Like this, the gas barrier passed into from air inlet 1 has been become 5 pieces by deflector 5, makes gas pass into cloth bag 4 more even.
Further, the top of described deflector 5 than the bottom of deflector 5 near air inlet 1.Because deflector 5 blocks the effect of air-flow, a part of big particle collision is trapped on deflector 5, and deflector 5 is tilted to down the landing contributing to particle.If deflector 5 and base plate angle are greater than 90 °, deposited particles on deflector 5 blows afloat by air-flow, produces reentrainment of dust, is unfavorable for dedusting.
Further, the height of described deflector 5, gas approach axis in air inlet 1, increases successively, and is all positioned at above air inlet 1 bottom from the bottom of nearest n-1 the deflector 5 of air inlet 1.Such as, 15-25mm is increased progressively highly successively.Air-flow enters in jet state in ash bucket 2, and impact first piece of deflector, a part of gas rises along deflector, and a part of gas produces and streams.Therefore, increased highly successively by deflector 5, rear one piece of deflector tackles streaming of last piece of deflector, enters in cloth bag 4 until all tackled by gas.
Further, from the bottom of air inlet 1 deflector farthest in described deflector 5, with the bottom of air inlet 1 in the same horizontal line, or be positioned at the below of bottom of air inlet 1.From the bottom of air inlet 1 deflector 5 farthest, with the bottom of air inlet 1 in the same horizontal line, or be positioned at the below of bottom of air inlet 1.Like this, from the gas that air inlet 1 passes into, can not directly impact on the wall of ash bucket 2.First the gas passed into from air inlet 1 can directly flow to each deflector 5.This is conducive to the generation being avoided refluxing.
Further, described deflector 5 is steel plate.The shock-resistant ability of steel plate is strong, so make deflector 5 with steel plate, can bear the gas impact that air inlet 1 passes into.
Further, the top of a described each deflector 5 row air vent 6 rearward in adjacent two row air vents 6.Air-flow is tackled by deflector 5, rises along deflector 5, and air-flow enters in the space between deflector 5 and casing 3 base plate, carries out second time shunting, and then flows in cloth bag 4.If the row air vent 6 that the top of deflector 5 is forward in adjacent two row air vents 6, the air-flow so risen along deflector 5 can directly wash away bottom cloth bag 4, produces larger load, wearing and tearing cloth bag 4.A row air vent 6 rearward in adjacent two row air vents 6, refers to the row air vent 6 away from air inlet 1 in adjacent two row air vents 6.
The course of work of the guiding device of said structure is: from the air inlet 1 of ash bucket 2, pass into gas, gas enters ash bucket 2, flows to the deflector 5 relative with air inlet 1.Air-flow is divided into n+1 region by deflector 5, enters uniformly in the cloth bag 4 of casing 3.As shown in Figure 1, air-flow is divided into five parts under the effect of deflector 5, and every part, along the deflector 5 of diverse location, is moved obliquely with different inclination angles.By arranging deflector 5 in ash bucket 2, for the feature of sack cleaner air-flow uneven distribution, the air-flow of deduster entrance is improved.Do not arrange deflector in common deduster, inlet air flow is comparatively large due to wind speed, produces strong jet effect in deduster porch.Air-flow enters in ash bucket the base plate impacting deduster, and a part of air-flow rises along base plate fast with larger speed, forms transversal flow to cloth bag.Another part air-flow flows downward along base plate, forms significantly backflow in ash bucket.And in patent of the present invention, the air-flow passed into from air inlet 1 is by after the deflector 5 of one group of differing tilt angles and differing heights, first part big particle strikes the diversed plate 5 of deflector 5 and traps, and then landing is in ash bucket, secondly air-flow enters in the gap between deflector 5 and casing 3 base plate by deflector 5 respectively, under respective gas pressure, redistribute air-flow uniformly, flow in cloth bag 4.Air-flow reduces in ash bucket the phenomenon occurring refluxing by the shunting action of deflector 5, avoid reentrainment of dust.After shunting, air velocity is relatively little, and air-flow can not produce serious impact to cloth bag after entering deduster, and deduster interior flow field is also more even, not only improves the efficiency of dust collection of deduster, also increases the service life of cloth bag.
