Kinematics analysis is carried out as shown in Figure 4 to rotating brush 11.

Can be obtained by the velocity composite of particle

$\stackrel{\→}{V}={\stackrel{\→}{V}}_0+{\stackrel{\→}{V}}_r---\left(1\right)$

In formula,For brush filament 111 earth point absolute velocity (m/s)；Pace (m/s) for sweeper；For Rotate brush 11 tangential velocity (m/s) in this place,R is the radius (m) rotating brush 11；ω is for rotating brush The rotating speed (rad/s) of 11.As can be seen from Figure 4

$\mathrm{\φ}={\cos }^{-1}\left(\frac{V_0-\mathrm{r\ω}\cos \mathrm{\α}}{\sqrt{V_0+r^2{\mathrm{\ω}}^2-2V_0\mathrm{r\ω}\cos \∂}}\right)---\left(2\right)$

In formula, Φ is brush filament 111 earth pointPace with sweeperBetween angle；α is for rotating brush 11 tangential velocities in this placeWithBetween angle, and α=pi/2+β；β is at this and center, brush filament 111 ground area Line, withBetween angle.Assume the pace of sweeperConstant, it is definite value at arbitrary earth point then α.From Fig. 4 Understand, along with the increase of rotation brush 11 rotational speed omega,Increase,Increase, and Φ also increases.With Φ in certain scope In, along withIncrease, the speed that grit enters in suction channel 3 is the biggest, and the wind speed of suction channel 3 suction have to be larger than rubbish The floating velocity of rubbish, in the case of wind speed is certain,Increase be equivalent to reduce the floating velocity of rubbish, thus be conducive to Improve sweeping efficiency.Simultaneously when initial Φ is optimal value (position being inhaled into most beneficial for rubbish), now along with the increasing of Φ Greatly, sweeping efficiency can reduce.In like manner, when initial Φ is less than optimal value, along with the increase of Φ, sweeping efficiency can increase.From More than analyze and understand, after the optimal value of Φ determines, on the premise of ensureing high sweeping efficiency, if cleaning ability to be improved (improve and clean speed), then should rotate the rotational speed omega of brush 11, make Φ constant according to formula (2) coupling.WhenDuring increase, Increasing the most accordingly, guarantee Φ is constant, now the absolute velocity of brush filament 111 earth pointIncrease, beneficially sweeping efficiency Raising.

The type selecting of the blower fan that aerodynamics analysis arranges with suction channel 3:

Floating velocity general algorithmic method subregion floating velocity trial and error procedure

Trizonal R according to resistance_eNumber can obtain corresponding computing formula with resistance coefficient C relation

(a) viscous drag district R_e≤1

$V_0=\frac{{d_r}^2({\mathrm{\ρ}}_s-\mathrm{\ρ})g}{18\mathrm{\μ}}---\left(3\right)$

This formula is the Stokes formula of viscous drag district floating velocity.Corresponding particle size range:

$d_s\≤1.225{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}---\left(4\right)$

(b) transition region l≤R_e≤500

$V_0=1.195d_s{\left[\frac{{({\mathrm{\ρ}}_s-\mathrm{\ρ})}^2}{\mathrm{\μ\ρ}}\right]}^{1/3}---\left(5\right)$

This formula is the A Lian formula of transition region floating velocity.

Corresponding particle size range:

$0.915{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}\≤d_s\≤20.4{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}---\left(6\right)$

(c) pressure drag district 500≤R_e≤2×10⁵

$V_0=5.45\sqrt{\frac{d_s({\mathrm{\ρ}}_s-\mathrm{\ρ})}{\mathrm{\ρ}}}---\left(7\right)$

This formula is the Newton's formula of pressure drag district floating velocity.

Corresponding particle size range:

$20.4{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}\≤d_s\≤1100{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}---\left(8\right)$

When Practical Calculation, first go out the scope of application according to closely knit density and particle diameter tentative calculation, it is then determined that use which formula Calculate.

In formula: V₀The floating velocity of spherical object, m/s

ρ_sThe closely knit density of object, kg/m³

R_eReynolds number, in order to be different from pipe flow Reynolds number, and the turbulent flow Reynolds number of referred to as object, in air conveying The also referred to as Reynolds number of granule

The density of ρ fluid, kg/m³

The dynamic viscosity of μ fluid, N s/m²

The material particles shape of actual fed is the most irregular.Material particle in irregular shape and spheroidal particle phase Ratio, typically its resistance are relatively big, and sedimentation velocity is less, so its floating velocity can be with shape correlation coefficients Φ to the most spherical Obtain after the floating velocity correction of object:

$V_f^{\′}=\frac{V_f}{\sqrt{\mathrm{\φ}}}---\left(9\right)$

In formula: V '_fThe floating velocity of material in irregular shape

V_fThe floating velocity of globular material

Φ shape correlation coefficients

Shape correlation coefficients Φ in the middle of the calculating of table 1 floating velocity

Sequence number	Body form	Φ value
			1	Spherical	1
2	Oval	1.06
			3	Irregularly shaped object	1.17

20C⁰Time air density p=1.2kg/m³, μ=1.81 × 10^-5N·s/m²

Assume that suction channel 3 to aspirate the finger stone of an a diameter of 1cm, the density of finger stone be ρ_s=2.8×10³kg/ m³

Understand in pressure drag district, data substituted in formula (7) and obtain:

$V_0=5.45\sqrt{\frac{d_s({\mathrm{\ρ}}_s-\mathrm{\ρ})}{\mathrm{\ρ}}}=26.3m/s$

Corresponding particle size range substitutes into formula (8) and obtains:

$20.4{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}\≤d_s\≤1100{\left[\frac{{\mathrm{\μ}}^2}{\mathrm{\ρ}({\mathrm{\ρ}}_s-\mathrm{\ρ})}\right]}^{1/3}=0.0927\mathrm{cm}-5\mathrm{cm}$

So the floating velocity of the finger stone of a diameter of 1cm in irregular shape is from formula (9):

$V_f=V_f^{\′}\sqrt{\mathrm{\φ}}=28.4m/s$

Additionally list floating velocity such as following table 2V of other several materials_Outstandingm/s

Title	Floating velocity	Title	Floating velocity	Title	Floating velocity
						Semen Tritici aestivi	9—11	Rice	9—12	Semen Brassicae campestris	8
Flour	2—3	Big bran (rice husk)	2—3.5	Herba bromi japonici	8—9
						Semen arachidis hypogaeae	11—15	Semen Pisi sativi	15—17.5	Semen Maydis	10—14
Cast iron pellets	23.5	Sorghum vulgare Pers.	9.8—11.8	Semen Fagopyri Esculenti	7.5—8.7

To sum up taking floating velocity is 28.4m/s, as long as so wind speed will be drawn onto suction channel more than 28.4m/s then object Until in refuse bin in 3, so air quantity is:

Q=VS (10) (V is wind speed, and S is the sectional area of suction channel 3 air inlet)

Wind speed ν in suction channel 3, it is necessary to assure garbage energy reliably carries, the economy of work to be considered simultaneously. Wind speed is too high, and power consumption is excessive.Power consumption is almost directly proportional to the cube of wind speed.Wind speed is too low, to rubbish conveying capacity The adaptability of change is little, job insecurity, is susceptible to blocking or the situation that drops.So should ensure that transportation work stably may be used On the premise of leaning on, take low wind speed as far as possible.

Summary considers: takes V=29m/s, the cross-sectional diameter of air inlet is that 936mm obtains

Q=Q=VS=V π R²=19.94m³/s=71799m³/h

So the model of blower fan elects CBZ-120A as, flow is 72000m³/ h, total head is 320Pa, and static pressure is 150Pa, turns Speed is 150r/min, and frequency is 970Hz, power 15Kw, and engine model is YB180L-6-H.
