Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further;
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of vacuum heat-insulation plate central layer of the present invention dust arrester, comprise dirt pocket 10, dust catcher 30 and be located at the foraminous conveyer 20 carrying central layer in dirt pocket 10, dirt pocket 10 is stretched out at the initial and end two ends of described foraminous conveyer 20, be positioned at described dirt pocket 10 inherent foraminous conveyer 20 upper and lower and be respectively equipped with overdraught nozzle 41 and downstream nozzle 42, in described dirt pocket 10, form an inlet scoop 11 be connected with dust catcher 30.
In the present embodiment, foraminous conveyer 20 horizontal positioned is arranged in dirt pocket 10, have one at two opposition sidewalls of dirt pocket 10 and enter plate mouth 12 and plate outlet 13, the initial and end two ends of foraminous conveyer 20 are passed through to stretch out into plate mouth 12 and plate outlet 13, can with the equipment interconnection of upstream and downstream inter process, enhance productivity.Foraminous conveyer 20 adopts the conveyer belt with mesh or mesh, the gas that downstream nozzle 42 is blown out can blow to central layer to remove dust, as preferably, foraminous conveyer 20 selects Teflon guipure, nylon guipure, PE guipure, PVC guipure or metal mesh belt.
Dirt pocket 10 is seal cases, only leave that two opposition arrange enter plate mouth 12 and plate outlet 13 enters for central layer and sends, foraminous conveyer 20 is with flexible-core plate to enter in dirt pocket 10 dedusting again through plate outlet 13 out from entering plate mouth 12.
The jet hole of overdraught nozzle 41 and downstream nozzle 42 should be flat, corresponding with the width of whole central layer, what make blowout is a flat air-flow, to be convenient to blow off the dust of core plate surface, overdraught nozzle 41 and downstream nozzle 42 are all arranged in dirt pocket 10 near plate outlet 13 place, the air-flow that overdraught nozzle 41 and downstream nozzle 42 blow out should point to the direction into plate mouth 12 place, and inlet scoop 11 is arranged on and closes on into plate mouth 12 place, dust is kicked up blowing off near of plate outlet 13, the dust kicked up that blows off is being siphoned away by dust catcher 30 from inlet scoop 11 near one that enters plate mouth 12, dust is made to control to greatest extent in dirt pocket 10, avoid dust from entering plate mouth 12 or plate outlet 13 overflows.
As preferably, overdraught nozzle 41 becomes 45 ~ 60 degree of angles with the flow path direction that puffs away of downstream nozzle 42 with the horizontal plane at foraminous conveyer 20 place, and what the airflow direction of blowout roughly pointed to other end enters plate mouth 12 place.
Wherein overdraught nozzle 41, downstream nozzle 42 are connected with a compressed air supply system, what overdraught nozzle 41 and downstream nozzle 42 were blown out is compressed gas, blast controls at 1 ~ 3KPa, dust is made easily from entering plate mouth 12 and plate outlet 13 blows out, if blast is too small be also difficult to the dust effectively removing core plate surface if blast is excessive.
What is more important, overdraught nozzle 41, the blowout air quantity of downstream nozzle 42 and the suction air quantity of dust catcher 30 need be regulated, making the blowout air quantity of overdraught nozzle 41 and downstream nozzle 42 must be less than the suction air quantity of dust catcher 30, dust so just being prevented from entering plate mouth 12 or plate outlet 13 overflows.
Dirt pocket 10 lower sidewalls is also provided with a dust mouth 14, through the air-flow that overdraught nozzle 41, downstream nozzle 42 blow out, the dust of the central layer above and below on foraminous conveyer 20 is blown afloat, the most of dust wherein kicked up is siphoned away from inlet scoop 11 by dust catcher 30, and fraction dust freely drops on dirt pocket 10 bottom, can residual dust in easy cleaning dirt pocket 10 by arranging a dust mouth 14.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from present inventive concept.
