Abstract
The invention relates to a mechanical device for pneumatically transmitting materials, and particularly relates to a gas-solid mixing room for pneumatically transmitting flour. The gas-solid mixing room comprises a gas inlet 1, a material dropping hole 2, a mixing room 3, a reducing jetting section 4, an accelerating throat section 5, an expanding jetting section 6 and a gas-solid mixing outlet 7. The gas-solid mixing room has the characteristics that the power consumption is low and the material is carried, sucked and conveyed in an accelerating manner. The gas-solid mixing room is very simple and compact in structure, convenient to operate, easy to maintain, especially suitable for a user limited by the site to use, simple to maintain, low in maintenance cost, relatively high in conveying speed, in a disperse state and good in continuity.
Description
Technical field
The present invention relates to a kind of gas-solid mixing room of material pneumatic conveying system, be especially suitable for the Geldart-D particle of the vacuum pressure conveying dilute phase material of flour, continous way, Large Copacity, short range conveying can be carried out, belong to the technical field of air-transport system special mechanism.
Background technology
The gas-solid mixing room of the negative-pressure pneumatic conveying of traditional flour does not possess the accelerating action of high-speed jet, and therefore required fan delivery is large, power of motor is high, and integrated operation cost is high.
Summary of the invention
Object of the present invention improves the deficiencies in the prior art, a kind of accelerating action possessing high-speed jet is provided, required fan delivery is little, power of motor is little, the pneumatic transport equipment device that integrated operation cost is low, thus realize carrying out continous way, Large Copacity, short-range Geldart-D particle to dilute phase material.The object of the present invention is achieved like this: the present invention relates to a kind of material pneumatic transport equipment device, particularly relate to a kind of gas-solid mixing room of negative-pressure pneumatic conveying of flour, groove, comprise admission port 1, blanking port 2, blending box 3, convergent jet segment 4, accelerate aditus laryngis section 5, flaring jet segment 6, gas-solid mixing outlet 7 composition, after it is characterized in that material is gentle and flowing through mixing, being walked by carrying at a high speed suction after convergent jet segment 4, acceleration aditus laryngis section 5, flaring jet segment 6, being applicable to large operational throughput, short-range Geldart-D particle of dilute phase material.Described admission port 1 leads to air, is the passage of air-flow.Described blanking port 2 is positioned at below loader, is the passage of material.Described blending box 3 is handing-over area of space of blanking port 2 and admission port 1, and inner chamber is curve.Described convergent jet segment 4 is that material and air-flow are mixed by section, and inner chamber is the acceleration area of curve.Described acceleration aditus laryngis section 5 is maximum speed sections that material and air-flow accelerate, and inner chamber is straight line.Described flaring jet segment 6 be the mixed ejection of material and air-flow by section, inner chamber is the constant-speed section of curve.
the invention has the beneficial effects as follows:
1. consumption of power is low, and material is carried suction and accelerates conveying;
2, structure is very simple and compact, easy to operate, for ease of maintenaince, and is particularly suitable for those users by place restriction and uses, and safeguards simple and expense is low;
3, the speed of solid material conveying is higher, and in disperse state, continuity is good.
Accompanying drawing explanation
the gas-solid mixing room detail drawing of the Geldart-D particle of a kind of flour of Fig. 1:
1-admission port 2-blanking port 3-blending box 4-convergent jet segment 5-accelerates the outlet of aditus laryngis section 6-flaring jet segment 7-gas-solid mixing.
Detailed description of the invention
each portion composition of the gas-solid mixing room of the Geldart-D particle of embodiment 1 one kinds of flour and effect:
A kind of gas-solid mixing room of Geldart-D particle of flour, comprise admission port 1, blanking port 2, blending box 3, convergent jet segment 4, accelerate aditus laryngis section 5, flaring jet segment 6, gas-solid mixing outlet 7 composition, after it is characterized in that material is gentle and flowing through mixing, being walked by carrying at a high speed suction after convergent jet segment 4, acceleration aditus laryngis section 5, flaring jet segment 6, being applicable to large operational throughput, short-range Geldart-D particle of dilute phase material.Admission port 1 leads to air, is the passage of air-flow.Blanking port 2 is positioned at below loader, is the passage of material.Blending box 3 is handing-over area of space of blanking port 2 and admission port 1, and inner chamber is curve.Convergent jet segment 4 is that material and air-flow are mixed by section, and inner chamber is the acceleration area of curve.Accelerating aditus laryngis section 5 is maximum speed sections that material and air-flow accelerate, and inner chamber is straight line.Flaring jet segment 6 be the mixed ejection of material and air-flow by section, inner chamber is the constant-speed section of curve.A kind of gas-solid mixing room of Geldart-D particle of flour is that air-flow is entered by admission port 1, material is entered by blanking port 2, air-flow and material mix at blending box 3, export 7 high speed jets by gas-solid mixing through convergent jet segment 4, acceleration aditus laryngis section 5, flaring jet segment 6 and go out, make material be able to laminar condition conveying.
the gas-solid mixing room principle of work of the Geldart-D particle of embodiment 2 one kinds of flour:
After the working medium with certain pressure level of roots blower flows through nozzle, form high-speed jet.This jet produces the gas in blending box and entrainments and rolling action in advance process, thus in blending box 3, forms certain negative pressure.Like this, just form certain pressure reduction between hopper and blending box 3, material just enters blending box 3 under this differential pressure action, and gas jet entrainment with rolling action under enter mixation tube section.At mixation tube section, gas-solid two-phase mixes further, enters Pneumatic conveying pipeline thereafter after diffuser supercharging.
