Description

A kind of air conveying chute for powder
Technical field
The utility model relates to air conveyer flume, particularly a kind of air conveying chute for powder.
Background technology
Air conveyer flume claims again the wind groove, is a kind of pneumatic transport equipment for delivery of the dry powdery material.Air conveyer flume because there are not rotatable parts, is easy to safeguard in convey materials, good airproof performance, noiselessness, safety of operation is reliable, little power consumption, change carry convenient, and can the multiple spot feeding and multiple discharge and being widely used.
The equipment that needs powder to carry for present concrete mixing plant etc., generally all be to carry powder with conveyor screw, the characteristics of conveyor screw are that the motor and speed reducer equal power device will be arranged, consume a large amount of electric energy in the work, and the transfer unit that contacts with powder of wearing and tearing, simultaneously the conveying of spiral is the conveying of straight line, can not carry by bend, realize that bend is carried just must to make up to realize by some straight line spirals.
Just upper the wind groove all is to produce in the builder's temporary shed of small workshop mode at present, exists technique to fall behind, and equipment is poor, and production efficiency is low, yields poorly, and past-sale service such as does not catch up with at the shortcoming, has seriously restricted energy-saving powder and has carried applying of skewed slot.
Summary of the invention
Technical problem to be solved in the utility model is, and is not enough for prior art, and a kind of air conveying chute for powder is provided, and utilizes Air Flow to carry to be suspended in the powder of air conveyer flume, realizes that farthest the concrete mixing plant powder carries.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of air conveying chute for powder, comprise flange 1 and the tubulose cell body 3 that is obliquely installed, described flange 1 upper end open is communicated with the powder storehouse, described flange 1 lower end is provided with air chamber 6, be provided with ventilative canvas 2 between described air chamber 6 and described flange 1 lower ending opening, described flange 1 one sides are communicated with described cell body 3 head ends, and described cell body 3 tail ends below is provided with two discharging openings 10; Described flange 1 is provided with valve with described cell body 3 joints; Described cell body 3 belows are provided with the tracheae 4 that is connected with air engine, and described tracheae 4 is communicated with described cell body by several T-pipe joints 5, and described tracheae 4 is communicated with described air chamber 6 by two pass joints.
As preferred version, described cell body 3 comprises some joint feed channels 7, and described respectively saving between the feed channel 7 is tightly connected by flange 8, and described feed channel upper end is provided with inspection door, is fixed with loam cake 9 on the described inspection door.
As preferred version, described cell body 3 adopts steel plate to make.
Compared with prior art, the beneficial effect that the utility model has is: the utility model utilizes Air Flow to carry to be suspended in the powder of air conveyer flume, has realized that farthest the concrete mixing plant powder carries.
Description of drawings
Fig. 1 is the utility model one example structure scheme drawing.
The specific embodiment
As shown in Figure 1, the utility model one embodiment comprises flange 1 and tilted-putted tubulose cell body 3, described flange 1 upper end open is communicated with the powder storehouse, described flange 1 lower end is provided with air chamber 6, be provided with ventilative canvas 2 between described air chamber 6 and described flange 1 lower ending opening, described flange 1 one sides are communicated with described cell body 3 head ends, and described cell body 3 tail ends below is provided with two discharging openings 10; Described flange 1 is provided with valve with described cell body 3 joints; Described cell body 3 belows are provided with the tracheae 4 that is connected with air engine, and described tracheae 4 is communicated with described cell body by several T-pipe joints 5, and described tracheae 4 is communicated with described air chamber 6 by two pass joints 11.
Described cell body 3 comprises some joint feed channels 7, and described respectively saving between the feed channel 7 is tightly connected by flange 8, and described feed channel upper end is provided with inspection door, is fixed with loam cake 9 on the described inspection door.
Described cell body 3 adopts steel plate to make.
Described cell body 3 cross-sectional planes are rectangle.
Air conveyer flume is be used to the continous way pneumatic transport equipment that is tilted to lower conveying dry powdery material (as: cement, raw material, fly ash, flour, french talc, rock phosphate powder etc.).
During convey materials, material is by powder storehouse feeding flange, flow out through cell body tail end discharging opening, simultaneously be blown into pressurized air by Air compressor to the lower house air chamber, pressurized air is fluidized material by ventilative canvas, because cell body has downward gradient, fluidization material under Action of Gravity Field just along cell body to front slide, reach the conveying purpose.
Air conveyer flume skewed slot traffic capacity can be calculated as follows:
Q=0.98×3600S.v.ρ
In the formula: Q-traffic capacity, t/h; (thickness of feed layer is generally 50~80mm) m to S-material sectional area 2The flowing velocity of v-material, m/s(gradient 4% is got 1.0 m/s; 5%; Get 1.25m/s; 6%; 1.5m/s); ρ-material volume weight, t/m 3(inflation cement: 0.75~1.05t/m 3Inflation cement slurry: 0.7~1. 0t/m 3Inflation coal dust: 0.4~0.6t/m 3Inflation fly ash 0.7~1.0:t/m 3)
The air consumption of air conveyer flume can be calculated by the following formula degree:
V=60BLa
In the formula: V-air consumption, m 3/ h; B-skewed slot width, mm; L-chute length, mm;
A-unit area air consumption, m 3/ m 2Air-permeable layer min(is usually by 1.5~3 m 3/ m 2Air-permeable layer min).
The air pressure of air conveyer flume:
The blast of the required blower fan of air conveyer flume should be greater than resistance and the bed of material resistance sum of air-permeable layer.Blast is generally 4000~6000Pa.Specification is large, get high value when fed distance is long, usually presses 5000Pa.
