The restriction of scope.
As it is shown in figure 1, the illustrative examples of the dust collecting provided for the present invention, at this
In illustrative examples, dust collecting includes collecting tank 1, is provided with collecting board in collecting tank 1
2, collecting board 2 is for collecting the dust fallen, and the end face of collecting board 2 is provided with electrostatic attraction board 3,
Electrostatic attraction board 3 connects electric supply installation 4, and electric supply installation 4 can be located at the sidewall of collecting tank 1,
Electric supply installation 4 is for providing power supply for electrostatic attraction board 3, and electrostatic attraction board 3 is in "on" position
Under can produce electrostatic with adsorption of dust, it is possible to reach to prevent dust splashes so that dust
Enter the effect of fixing bleeding point, and as much as possible fibre dust can be collected collecting tank 1
In, improve the collection rate of dust.
In above-mentioned dust collecting, collecting board 2 is located in collecting tank 1, and can will collect
Groove 1 is divided into upper and lower two-layer, collecting board 2 to be turning plate, and the dust collected at collecting board 2 reaches
Under the state of setting weight, collecting board 2 can overturn, with the dust collected by collecting board 2
Pour the lower floor of collecting tank 1 into.After collecting board 2 upset, its another side still can continue to collect powder
Dirt.
The two sides of collecting board 2 all can be provided with electrostatic attraction board 3, along with the upset of collecting board 2,
Dust is collected alternately as end face in the two sides of collecting board 2.Electric supply installation 4 is located at collecting board 2 and is turned over
After having turned, it is positioned at the position of the electrostatic attraction board 3 of end face, is turned to end face for collecting board 2
Electrostatic attraction board 3 power, owing to collecting board 1 is turned to the electrostatic attraction board 2 of bottom surface and supplies
Electric installation 4 disconnects, and therefore, collecting board 2 is turned to electrostatic attraction board 3 power-off of bottom surface, quiet
Electricity disappears, and beneficially dust falls into the lower floor of collecting tank 1.
One, preferably or in alternative embodiment, electric supply installation 4 can be inhaled to use fast mode of inserting for electrostatic
Attached plate 3 is powered, and the plug of electric supply installation 4 can be fixedly installed on the sidewall of collecting tank 1, once
Collecting board 2 overturns, it is possible to ensures that the electrostatic attraction board 3 of side (being positioned at end face) upward is connected and supplies
Electric installation 4, and electrostatic attraction board 3 deenergization of side (being positioned at bottom surface) down, can either be just
Fall in dust, be prevented from again electrostatic attraction board 3 down and intake short circuit.
In each embodiment above-mentioned, collecting board 2 can pass through power set with connecting power device
Driving collecting board 2 to overturn, the middle part of collecting board 2 can arrange rotating shaft 5, and power set drive
Connection rotating shaft 5, collecting board 2 can rotate with rotating shaft 5.Collecting board 2 is also provided with weighing
Sensor, LOAD CELLS electrical connection power set, the dust collected at collecting board 2 reaches to claim
During the weight that weight sensor sets, LOAD CELLS is signaled to power set, power set
Collecting board 2 is driven to overturn, so that the dust that collecting board 2 is collected to be poured into the lower floor of collecting tank 1.
By arranging power set and LOAD CELLS is capable of the automatic turning of collecting board 2, it is achieved
The automatization of dust collection, improves dust collection efficiency.
Further, owing to the two sides of collecting board 2 is equipped with electrostatic attraction board 3, correspondence,
The two sides of collecting board 2 all can be provided with LOAD CELLS, in order to realizes collecting board 2 back and forth
Automatic turning.
Falling for the ease of dust, the top of collecting tank 1 is also provided with for scraping dust
Scraper 6.
In order to the dust collected in preventing collecting tank 1 further disperses everywhere, produce powder
Dustiness contaminates, and the present invention also connects in the bottom of collecting tank 1 water inlet pipe 7 and drain pipe 9, enters
Water pipe 7 is provided with inlet valve 8, and drain pipe 9 is provided with water discharging valve 10, and inlet valve 8 is opened,
For to collecting tank 1 water flowing, being beneficial to dust soluble in water, prevent dust from dispersing everywhere；?
When dust water solution in collecting tank 1 reaches a certain amount of, water discharging valve 10 can be opened, with
Dust water solution in collecting tank 1 is discharged.
Drain pipe 9 can be connected to collecting tank 11, and collecting tank 11 can be provided with draw-off pump 12,
Draw-off pump 12 provides power, is used for the dust water solution extraction in collecting tank 1 to collecting tank
In 11, preventing dust water solution overfill in collecting tank 1, the continuation affecting dust is collected.
The work process of one specific embodiment of the dust collecting that the present invention provides is:
Glutinous fiber viscous on vat 13 is scraped by scraper 6, forms fibre dust, and collecting board 2 is positioned at
The electrostatic attraction board 3 of end face is connected energising adsorbing fiber dust with electric supply installation 4, is fixed by dust
At collecting board 2；When the dust of collecting board 2 end face reaches constant weight when, trigger weighing and sensing
Device so that collecting board 2 is overturn by rotating shaft 5, inverts fibre dust from the upper strata of collecting tank 1
Lower floor to collecting tank 1；Now, the electrostatic attraction board 3 being just positioned at end face departs from electric supply installation 4,
Fibre dust power-off comes off, and the electrostatic attraction board 3 being just positioned at the collecting board 2 of bottom surface forwards top to
Face is accessed electric supply installation 4 and is proceeded the Electrostatic Absorption of dust, therefore, and will not be because of collecting board 2
Upset causes dust collection to stop；Now opening inlet valve 8, clear water is entered by water inlet pipe 7 and receives
Collection groove 1 so that dust incorporates in clear water, closes water inlet (after such as five minutes) after certain time
Valve 8, opens water discharging valve 10, and due to the effect of draw-off pump 12, collecting tank 11 is that negative pressure is true
Dummy status, once opens water discharging valve 10, the water of collecting tank 1 lower floor and fibre dust by strength
Extract out and enter collecting tank 11, after extraction certain time, close water discharging valve 10.
Work process by above-mentioned: dust collecting utilizes Electrostatic Absorption dust, when dust reaches
The when of to constant weight, collecting board 2 overturns, and dust is poured into the lower floor of collecting tank 1, adds water
Dust is entered in water, utilizes draw-off pump 12 to be extracted out by the sewage containing dust, therefore, it can
Most of fibre dust that scraper 6 is scraped enters the receipts specified by fibre dust collection device
Collection tank, without producing dispersing everywhere of dust air-flow, and then avoids dust pollution.
Present invention also offers a kind of reconstituted tobacoo production system, it includes any of the above-described embodiment
In dust collecting.
Finally should be noted that: above example only in order to technical scheme to be described and
Non-to its restriction；Although the present invention being described in detail with reference to preferred embodiment, affiliated
The those of ordinary skill in field is it is understood that still can enter the detailed description of the invention of the present invention
Row is revised or portion of techniques feature is carried out equivalent；Without deviating from technical solution of the present invention
Spirit, it all should be contained in the middle of the technical scheme scope that the present invention is claimed.
