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.
The specific embodiment
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 of the interior conveying central layer of dirt pocket 10, dirt pocket 10 is stretched out at the initial and end two ends of described foraminous conveyer 20, be positioned at inherent foraminous conveyer 20 upper and lowers of described dirt pocket 10 and be respectively equipped with overdraught nozzle 41 and downstream nozzle 42, the inlet scoop 11 being connected with dust catcher 30 in the interior formation one of described dirt pocket 10.
In the present embodiment, foraminous conveyer 20 horizontal positioned are 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 by entering plate mouth 12 and plate outlet 13 stretches out, can with the equipment interconnection of upstream and downstream inter process, enhance productivity.Foraminous conveyer 20 is to adopt the conveyer belt with mesh or mesh, the gas that downstream nozzle 42 blows out can be blown to central layer bottom to remove dust, as preferably, foraminous conveyer 20 is selected Teflon guipure, nylon guipure, PE guipure, PVC guipure or metal mesh belt.
Dirt pocket 10 is seal cases, only leave two opposition settings enter plate mouth 12 and plate outlet 13 enters and sends for central layer, foraminous conveyer 20 is with flexible-core plate to enter the interior dedusting of dirt pocket 10 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 to blow out is a flat air-flow, be convenient to the to blow off dust on central layer surface, it is interior near plate outlet 13 places that overdraught nozzle 41 and downstream nozzle 42 are all arranged on dirt pocket 10, the air-flow that overdraught nozzle 41 and downstream nozzle 42 blow out should point to into the direction at plate mouth 12 places, and inlet scoop 11 is arranged on and closes on into plate mouth 12 places, dust is blowing off and is kicking up near of plate outlet 13, the dust of kicking 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 controlled in dirt pocket 10 to greatest extent, avoid dust from entering plate mouth 12 or plate outlet 13 overflows.
As preferably, the flow path direction that puffs away of overdraught nozzle 41 and downstream nozzle 42 becomes 45 ~ 60 degree angles with the horizontal plane at foraminous conveyer 20 places, and what the airflow direction blowing out roughly pointed to other end enters plate mouth 12 places.
