In order to achieve the above object, the technical scheme that the utility model adopts is: comprise delivery chute body, be provided with fluidisation cloth in delivery chute body, intrinsic delivery chute cavity isolation is become upper and lower two parts by fluidisation cloth, Wei Liao chamber, top, and bottom is air chamber; The end face of delivery chute body front end offers feeding mouth, and rear end end face is connected with exhaust duct; On the front end face of delivery chute body, be connected with the first airduct, delivery chute body is connected with the first centrifugal fan by the first airduct; On the aft end face of delivery chute body, be provided with discharging opening; The bottom surface of delivery chute body offers some breather ports, and these breather ports are connected with the second centrifugal fan by the second airduct.
Described delivery chute body comprises upper groove body and the lower groove that opening is oppositely arranged and snaps together, and the both ends of the surface sealing of upper groove body and lower groove arranges; Fluidisation cloth is arranged between upper groove body and lower groove, and the cavity between fluidisation cloth and upper groove body is material chamber, and the cavity between fluidisation cloth and lower groove is air chamber; The first airduct is connected on the front end face of upper groove body, and the second airduct is connected on the bottom surface of lower groove; Feeding mouth is opened on the end face of upper groove body front end, and discharging opening is arranged on the aft end face of upper groove body.
Described exhaust duct is connected with extraneous dust exhaustor.
The rectangular structure that described delivery chute body is hollow.
Described delivery chute body is obliquely installed, and the height of feeding mouth one side is greater than the height of discharging opening one side.
Described delivery chute body is horizontally disposed with.
Compared with prior art, the utlity model has following beneficial effect:
The utility model arranges fluidisation cloth in delivery chute, by fluidisation cloth, delivery chute inner space is divided into material chamber and air chamber, and be communicated with respectively two centrifugal fans, material can be suspended on fluidisation cloth and in the promotion current downflow of gas, the utility model overcomes conventional air and carries skewed slot in the course of conveying of powder material, powder flows by Action of Gravity Field merely, poor fluidity, the problem that transport efficiency is low, can effectively avoid skewed slot buildup, putty phenomenon, can reduce the setting angle of air conveyer flume simultaneously, when being installed, air flume further reduced by space constraint, short range also can realize powder horizontal feed.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the sectional side view of the utility model delivery chute.
Wherein, 1 is the first centrifugal fan; 2 is the first airduct; 3 is feeding mouth; 4 is upper groove body; 5 is fluidisation cloth; 6 is exhaust duct; 7 is discharging opening; 8 is lower groove; 9 is the second airduct; 10 is the second centrifugal fan.
The specific embodiment
Be described in further detail below in conjunction with accompanying drawing the utility model:
Referring to Fig. 1, the utility model comprises delivery chute body, and the rectangular structure that delivery chute body is hollow is provided with fluidisation cloth 5 in delivery chute body, and intrinsic delivery chute cavity isolation is become upper and lower two parts by fluidisation cloth 5, Wei Liao chamber, top, and bottom is air chamber; The end face of delivery chute body front end offers feeding mouth 3, and rear end end face is connected with exhaust duct 6, and exhaust duct 6 is connected with extraneous dust exhaustor; On the front end face of delivery chute body, be connected with the first airduct 2, delivery chute body is connected with the first centrifugal fan 1 by the first airduct 2; On the aft end face of delivery chute body, be provided with discharging opening 7; The bottom surface of delivery chute body offers some breather ports, and these breather ports are connected with the second centrifugal fan 10 by the second airduct 9.Delivery chute body comprises upper groove body 4 and the lower groove 8 that opening is oppositely arranged and snaps together, and the both ends of the surface sealing of upper groove body 4 and lower groove 8 arranges; Fluidisation cloth 5 is arranged between upper groove body 4 and lower groove 8, and the cavity between fluidisation cloth 5 and upper groove body 4 is material chamber, and the cavity between fluidisation cloth 5 and lower groove 8 is air chamber; The first airduct 2 is connected on the front end face of upper groove body 4, and the second airduct 8 is connected on the bottom surface of lower groove 8; Feeding mouth is opened on the end face of upper groove body 4 front ends, and discharging opening 7 is arranged on the aft end face of upper groove body 4.The high-pressure blast that the second centrifugal fan 10 produces enters air chamber, sees through fluidisation cloth 5 and makes to expect that indoor powder suspension becomes fluidised form.The high-pressure blast that the first centrifugal fan 1 produces directly enters the material that material chamber promotes to be in fluidised form and accelerates to flow to discharging opening 7.The high-pressure blast being produced by centrifugal fan 1 promotes to expect that indoor powder moves by force, the thrust that centrifugal fan 1 produces and material produce the component along skewed slot direction of tilt from the gravity of experiencing, the powder that common promotion is in fluidised form flows, and has increased the flowing velocity of material, has improved transport efficiency.
In addition, delivery chute body of the present utility model can be obliquely installed, and in the time that delivery chute body is obliquely installed, the height of feeding mouth 3 one sides is greater than the height of discharging opening 7 one sides.In addition, delivery chute body of the present utility model also can be horizontally disposed with.
Principle of the present utility model:
The high pressure air that centrifugal fan that the utility model is communicated with air chamber produces makes to expect indoor to be material suspendedly in flow-likely by fluidisation cloth, and the high pressure air promotion of the centrifugal fan generation being directly communicated with material chamber is in flow-like powder and flows downward along upper groove body.When delivery chute body tilts, the wind-force that the centrifugal fan being connected with upper groove body material chamber produces adds the gravity of powder self, accelerates the flowing velocity of material in delivery chute body, improves transport efficiency, makes to carry more unimpeded.When delivery chute body level, the gravity of powder can not impel Flow of Goods and Materials, and the high pressure air that the centrifugal blower being connected with upper groove body material chamber produces can promote material and do short range horizontal feed, reaches mass transport object.
Above content is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the protection domain of the utility model claims.
