Firmly soil, and the dust in soil can be extracted out by negative-pressure air fan 34, be fixed with transmission device below 33 discharge port of feeder pipe
8, the soil in feeder pipe 33 is fallen on transmission device 8, and is transported at collection with transmission device 8, removes manual handling collection from
Trouble.
The sieve nest is located on 32 middle section position of sieve chamber, under being between the sieve nest and the discharge port of the sieve chamber
Expect area 35, it is goblet bottom of a cup planform, institute that the inner wall of the discharging area 35, which restrains the shape to be formed close to bottom section,
It states goblet bottom of a cup structure and converges to middle position and be provided with blanking osculum, bore is small to ensure that vacuum effect is more preferable, downward
Air pressure is bigger, and soil will not generate accumulation in sieve chamber 32, and the blanking osculum and the perforation of feeder pipe 33 connect, and sieves the soil in chamber
Earth is fallen into feeder pipe 33 by blanking osculum.
The discharging area 35 is equipped with multi-deck screen ring 36 along its inner wall, sieve ring 36 described in multilayer correspond to sieve nest it is vertical under
Direction is expected there are area of slack water 37, and area of slack water 37 is that setting sieve ring 36 provides sufficient space, it is ensured that sieve 36 reasonable layout of ring, more
Buffer function is played well, is feeder pipe 33 below the area of slack water 37；Every layer of sieve ring 36 is intended to from outer ring to inner ring
The inclination of 33 direction of feeder pipe slides the soil fallen on sieve ring 36 downwards, and upper one layer of sieve ring, 36 inner ring profile is greater than next
Layer sieve 36 outer ring profile of ring, soil can be fallen on next layer of sieve ring 36 from upper one layer of sieve ring 36.
The sieve ring 36 is the high skin-friction coefficient high resiliency material of rubber-type；32 bottom of sieve chamber is connected with vibration
Device 38 is swung, the oscillator 38 drives the sieve chamber 32 in vertical direction oscillating movement, and the sieve chamber 32 of oscillating movement drives soil
Vibration is fallen, and accumulation is avoided the formation of, and there is elastomeric sieve ring 36 vibrating effect can be made more preferable.
Sieve 36 surface of ring is provided with through-hole up and down, since the sieve ring 36 is the high mantle friction system of rubber-type
Number high resiliency material, the most of soil sieved on ring 36 can fall from through-hole with oscillation, and upper one layer of sieve, 36 through-hole of ring is big
More soil is accepted in the sieve ring 36 of next layer of sieve 36 through-hole of ring, more upper layer, bigger through-hole can be to avoid Zinc fractions heap
Product.
The driving device includes drive shaft 2 and driving motor 5, and the drive shaft 2 is fixed along 9 axis direction of side plate

Feed inlet 4 is provided on plate 9, the feed inlet 4 is equipped with removable capping, constantly opens capping in charging, completion to be fed is again
Cover capping.
The shell 3 opens up through-hole 10, the 10 inner ring upper and lower end of through-hole and the drive with 2 junction of drive shaft
The distance of moving axis 2 is all larger than the amplitude of the oscillator 38, and shell 3 is avoided to send out with when 38 oscillating movement of oscillator with drive shaft 2
Raw collision.
9 inner wall of side plate is connected with strut 6, Auxiliary support side plate along axis direction.
A kind of working method of soil remediation gravity type soil screening plant:
The wind deflector 31 is rotated far from the sieve nest direction, is formed spacious air port, is convenient for feeding operation, opens the charging
Capping on mouth 4, is added soil to be sieved, covers capping, according to required vacuum magnitude, it is close or remote to rotate the wind deflector 31
From the sieve nest direction, ventilation gap 11 or spacious air port are formed, not only vacuum effect can be made more preferable when forming ventilation gap 11,
It diffuses out prevented also from the dust in soil, if the soil does not need larger negative pressure and can fall, and does not have biggish simultaneously
Dust can also directly select spacious air port to operate, convenient for observing the case where soil sieves in sieve nest at any time；
Opening the driving motor 5 drives the drive shaft 2 to rotate, to drive the sieve nest to rotate, so that in sieve nest
Soil rolling, slide, open simultaneously the negative-pressure air fan 34, negative-pressure air fan 34 extracts the air in feeder pipe 33 out outward,
Make to form top-down air-flow in the sieve chamber 32 and the feeder pipe 33, opening the oscillator 38 makes on the shell 3
Lower vibration, part soil in the sieve nest under the action of gravity and air pressure directly by the screening of the mesh structure layer 1,
Vertical fall enters in the feeder pipe 33, and part soil passes through the sieve knot under the action of centrifugal force, gravity and air pressure
The screening of structure layer 1 is fallen on the multi-deck screen ring 36 of area of slack water 37, since the sieve ring 36 is the high skin-friction coefficient of rubber-type
High resiliency material sieves the effect of vibration that most of soil on ring 36 drives the shell 3 in gravity, air pressure and oscillator 38
Under, it is successively fallen by the through-hole on sieve ring 36, since upper one layer of sieve ring, 36 inner ring profile is greater than next layer of 36 inner ring wheel of sieve ring
Exterior feature, the upper one layer soil sieved on ring 36 can be fallen on next layer of sieve ring 36, and be eventually fallen into feeder pipe 33, simultaneously because on
Layer sieve ring 36 accepts more soil, and farther from negative-pressure air fan 34, and vacuum effect region not as good as locating for lower screen ring 36, soil is more
Accumulation is easily formed, thus 36 through-hole of upper sieve ring is greater than 36 through-hole of lower screen ring, convenient for falling, avoids blocking, small part
Soil slides along sieve 36 upper surface of ring to next layer of 36 upper surface of sieve ring, and layer-by-layer staged slides into feeder pipe 33, under described
33 internal diameter of expects pipe is corresponding with the blanking osculum internal diameter that convergence is formed, so that 33 cavity volume of feeder pipe is smaller, vacuum effect is more preferable,
Soil in the feeder pipe 33 is fallen on transmission device 8, and is transported at collection with the transmission device 8, removes manpower transport from
The operation of soil, it is high-efficient.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
