Abstract

The invention provides a high-efficiency dry and wet dust recovering machine combining primary purification and secondary purification into a whole for manufacturers. In the machine, the upper part is a cylinder body, the lower end forms a cone, and the lower part of the cone is connected with an air sealing machine, wherein a purpose-made high-density stainless steel wire cloth filter drum is distributed on the periphery of the central axis of the cylinder body, the upper part of the filter drum is in a cylinder shape, and the lower part is in a cone shape; and a stainless steel bush used for supporting is close to the filter drum. A hollow pipe driven by a small motor to rotate is vertically erected in the center of the machine, and the upper end and the lower end of the pipe are fixed on associated components through bearings; the pipe is provided with dozens of blowing holes; an inlet at the upper end of the pipe is controlled by an electromagnetic valve to regularly inject compressed air; and a filtering net is oppositely blown to clear up adhered dust to ensure that the dust falls on the air sealing machine at the bottom of the cone and then discharged. After air containing dry and wet dust enters a circumferential space between the cylinder body and the filtering net from an air inlet of the cylinder body along a tangent line, crude dust automatically falls down, and air is exhausted into atmosphere from an air outlet on the top after very fine dust is filtered so that naked eyes cannot see the dust.

Description

Combined dust recovering machine with double purification

Technical field

The present invention for industries such as cereal processing, food in process of production, no matter the dust that various Work machines produce is dry dust, still wet dust all can be carried out the dust recovery new equipment of double purification.

Background technology

In industry production processes such as cereal processing, food, the dust that various Work machines are produced, dry dust purifies recovery easily.The cereal size reduction machinery easily produces aqueous vapor in operation process, when carrying out the double purification processing with existing pulse dust collector, because of filter bag is a fabric, there is the part aqueous vapor easily to be trapped in the fiber, stick together with fine dust, how long have more than is needed, constipation becomes the pasty state piece, have a strong impact on the air draught effect, have to filter bag is often changed cleaning.This recovery machine is succeeded in developing and has been solved a difficult problem in this respect, plays the existing irreplaceable effect of double purification cleaner.

Summary of the invention

In order to solve in the industry production processes such as cereal processing, food, the recovery difficult problem of the wet fine dust of generation the invention provides a kind of dried wet dust recovering machine, and this equipment collection just purifies, double purification is one, can all can effectively reclaim doing wet fine dust.

Recovery machine profile is a cylinder, and its lower end is a cone shape, and the cylinder side has the inlet (dust contained gas), and clean air outlet is arranged at top, and cone is that dust discharge airlock connects, and above-mentioned facility plays the function that common Asta-3746 just purifies.Establishing in cylinder inside with special special-purpose high density stainless steel wire cloth is that material adopts the folding filter cylinder of special process, and the top filter cylinder is cylindrical, and the bottom filter cylinder be a taper shape, passive stainless steel lining is arranged being close to the filter cylinder inboard.At the center of filter cylinder, stand vertically a hollow pipe, on relevant solid plate, pipe is rotated by driven by motor the pipe upper and lower end by bearing fixing.Have dozens of compressed air spraying hole on the hollow pipe, injection hole is arranged as spirality or vertical shape at the hollow pipe length direction.The inlet of pipe upper end by solenoid electric valve self-timing injecting compressed air, is cleared up the dust that is attached on the filter screen.Because the hollow pipe rotation, the dust of removing on the filter screen can not leave the dead angle.

Advantage of the present invention is simple in structure, and volume is little, and good permeability reclaims dried, wet dust efficient height.The user can be according to the recovery machine of how much matching respective model of handling air quantity.

Description of drawings

Accompanying drawing is that the present invention reclaims machine front view (broken section).

The specific embodiment

See also shown in the accompanying drawing, when dust laden air enters from tangent line inlet (dust contained gas), cylinder 8 outside 9 between cylindrical shell 8 and the high density stainless steel wire cloth filter cylinder behind the circuferential spacing, the dust of coarse size is under the effect of airflow centrifugal power and self gravitation, descend along cylinder, fall in the bottom discharging airlock 12 from cone tube 11, thereby finish the function that just purifies.

Fine dust is pressed close to the stainless steel wire cloth filter cylinder with air current flow and is carried out the double purification processing, and double purification is discharged parts combinations such as commutator, solenoid electric valve and finished by last cylindrical filtration cartridges 4, following conical filter cylinder 10, central vertical hollow pipe 6, air-flow.Filter cylinder is a filtering material with special special-purpose high density stainless steel wire cloth, adopts special process to fold and makes, and purpose is to increase a silk cloth filter area, reduces filtration velocity.The filter screen inboard has is close to the passive stainless steel lining 5 of a cloth, and cylindrical filtration cartridges 4 flanges suitable for reading are fixed by bolts on cylinder 8 loam cakes 3, and the end opening flange links to each other with lower cone shape filter cylinder 10 with bolt.Central vertical hollow pipe 6, upper and lower side are fixed on commutator 2 wallboards and conical filter cylinder 10 chassis with bearings respectively.Have dozens of compressed air spraying hole 7 on the pipe, other hollow pipe tube connectors 1 of pipe usefulness suitable for reading and solenoid electric valve join, and pipe has the driven by motor rotation.

When the air that contains fine solid particle passes filter cylinder, because of the fine dust granularity is far longer than the filter screen aperture, so fine dust can't pass through silk screen.Showing through use observing, entering the filtered air of atmosphere, the dust that the has been invisible to the naked eye phenomenon that leaks.

To filtering dust, pass through tube connector 1 injecting compressed air by the solenoid electric valve self-timing attached to the filter screen outer surface.Injection hole 7 contra-injections of compressed air from the hollow pipe 6 produce vibration to filter screen, dust are blown off, because of hollow pipe 6 rotates, so can not leave the dead angle to the cleaning of filter screen.

Fallen into dust discharge airlock 12 by the fine dust under blowing off in the lump from circular cone tube 11, and instant the discharge.

Air after filtering directly enters atmosphere with blower fan, thereby finishes the mission of double purification.
