Description
Technical field
The utility model relates to a kind of dust guard for ring-like material distributing machine, specifically a kind of for annular
The double-sealing device of material distributing machine.
Background technology
Ring-like material distributing machine is arranged on the material transfer equipment at large silo top, is storage silo and supplied materials Belt Conveying
Cloth between machine and conveying equipment.Supplied materials enters silo by top, storehouse material distributing machine, and material distributing machine realizes silo by positive and negative transferring
The uniform blanking of inner and outer ring.Material distributing machine is mainly by reversible airtight belt feeder, coal spout, travel driving unit, revolving support, current collector
The structure compositions such as actuating device, inner and outer ring sealing device, electric control system.Material is defeated by the belt feeder of trestle above silo
Delivering in coal spout, coal spout is connected with the reversible airtight belt feeder feeding mouth of lower section.In the course of the work, due to coal spout
It is relative motion with the feeding mouth at airtight belt conveyer gathering sill top, and material can produce airborne dust during declining, if
The most poorly sealed, can be excessive at its seam dust, easily cause environment pollution, bring to people healthy the biggest
Harm；Secondly, coal conveyor tool equipment works for a long time in the environment of dust concentration is higher, easily causes without planned outage and event
Barrier, brings great inconvenience to the operation of equipment.Therefore, for preventing the pollution of the environment and guarantee equipment is properly functioning, routine is
Use and coal spout is goed deep into reversible airtight belt feeder feeding mouth, or reduce material-falling hopper and reversible airtight belt feeder feeding mouth as far as possible
Gap.But after taking these measures, also have the phenomenon appearance that dust spills.
Utility model content
The technical problems to be solved in the utility model is: between existing between blanking port and the material blanking tube of annular material distributing machine
Gap, there is the phenomenon of flour dust overflow, causes environmental pollution in gap location, for solving the problems referred to above, it is provided that a kind of for annular cloth
The double-sealing device of machine.
The purpose of this utility model is achieved in that
A kind of double-sealing device for annular material distributing machine, is provided with machinery in material blanking tube and the overlapping position of blanking port close
Envelope, is provided with, in the outside of material blanking tube Yu blanking port overlapping position, the sealing that is flexible coupling.
Mechanical seal refers to arrange a circle dust board at the edge of blanking port, dust board be positioned at blanking port and material blanking tube it
Between.
Gap between dust board and material blanking tube is 3-8mm.
The described sealing that is flexible coupling refers to the outside of material blanking tube is provided with connector, and connector hangs with canvas, canvas
At least one circle outside material blanking tube, the lower end of canvas falls on the upper surface of blanking port.
Connector is steel ring, and steel ring is fastened by bolt.
Being additionally provided with a circle steel pipe on material blanking tube, steel pipe is positioned at the lower section of steel ring, and canvas rides over the outside of steel pipe, canvas
The width that lower end is laid on blanking port upper surface is 50-100mm.
Relative to prior art, this utility model arranges mechanical seal between material blanking tube and blanking port, and sets in outside
Put the sealing that is flexible coupling, between material blanking tube and blanking port during relative motion, mechanical seal and the side of the sealing dual-seal that is flexible coupling
Formula, plays good sealing effectiveness, reaches dust-proof purpose.

Detailed description of the invention
As shown in Figure 2 and Figure 3, a kind of double-sealing device for annular material distributing machine, at the weight of material blanking tube 1 with blanking port
It is provided with mechanical seal 6 at conjunction, the outside of material blanking tube 3 with blanking port overlapping position is provided with the sealing 5 that is flexible coupling.
Mechanical seal 6 refers to arrange a circle dust board 10 at the edge of blanking port, and dust board 10 is positioned at blanking port and blanking
Between pipe 3.
Gap between dust board 10 and material blanking tube 3 is 3-8mm, such as 5mm.
The described sealing 5 that is flexible coupling refers to the outside of material blanking tube 3 is provided with connector, and connector hangs with canvas, sail
Cloth is at least one circle outside material blanking tube 3, and the lower end of canvas falls on the upper surface of blanking port.
Connector is steel ring 7, and steel ring 7 is fastened by bolt fastener 8.
Being additionally provided with a circle steel pipe 9 on material blanking tube 3, steel pipe 9 is positioned at the lower section of steel ring 7, and canvas rides over the outside of steel pipe 9,
The width that the lower end of canvas is laid on blanking port upper surface is 50-100mm, such as 100mm.
This utility model includes a set of mechanical seal 6 device, a set of sealing 5 devices that are flexible coupling, first seal such as Fig. 2,
Fig. 3, at a deflector chute 2 end face blanking port circle dust board 10 weld around, blanking port one segment distance is goed deep in material blanking tube 3 lower end, and
Radial distance inside material blanking tube 3 and dust board 10 is 5mm, when material blanking tube 3 and deflector chute 2 relatively rotate around the center of circle, greatly
Avoid coal dust and spill.Second seals such as Fig. 3, at material blanking tube 3 lower end welding one circle pipe, the material blanking tube on the upside of pipe
Around circle half canvas outside 3, unnecessary half-turn repeats to be centered around on material blanking tube 3, then will with steel ring 7 and bolt fastener 8
Canvas upper end is fixed, and canvas lower end is put outside steel pipe 9, and length ensures that canvas is taped against deflector chute 2 end face and is layered on the length of end face
Reach 100mm, when material blanking tube 3 and airtight belt feeder 1 blanking port relatively rotate, after first seals, spill very
A small amount of coal dust all will be sealed up by canvas, thus serve and fully seal, and prevent the purpose polluted.
