Abstract

The invention relates to a net frame structure for removing dust. The net frame structure can effectively remove fine granular dust with high cohesive property and great adsorbility on the outer surface of a heated surface tube to ensure the heat exchange efficiency of the heated surface of a boiler. The net frame structure comprises the heated surface tube positioned horizontally, and is characterized in that cleaning brushes are sleeved on an outer circular surface of the heated surface tube; the shape of the inner part of the cleaning brush section is matched with the outer circular surface of the heated surface tube; the cleaning brushes are connected with one another into a whole through connecting rods; the outermost ends of the connecting rods are connected to the net frame; four corners of the net frame are arranged on guide rods which are positioned in axial direction and are parallel to the heated surface tube; and the net frame is externally connected with a power connecting mechanism.

Description

A kind of net frame structure for removing dust
(1) technical field
The present invention relates to the boiler plant technical field, be specially a kind of net frame structure for removing dust.
(2) background technology
The heating surface tube outer surface of existing boiler; After through long work; Be prone to be infected with the particle dust that caking property is high, adsorptivity is big; Because the existence of these dust, the heat exchange efficiency of boiler heating surface reduces, and the existing conventional way can't clean out the particle dust that these caking property are high, adsorptivity is big.
(3) summary of the invention
To the problems referred to above, the invention provides a kind of net frame structure for removing dust, it can effectively remove the particle dust that caking property is high, adsorptivity is big of heating surface tube outer surface, thereby guarantees the heat exchange efficiency of boiler heating surface.
Its technical scheme is such: it comprises the heating surface tube of horizontal arrangement; It is characterized in that: said heating surface tube periphery is set with cleaning brush; The interior shape in said cleaning brush cross section and the periphery of said heating surface tube coincide, and said cleaning brush interconnects through connecting rod and forms a whole, and said connecting rod outermost end is connected in rack; Four jiaos of said rack are installed on the axial arranged guide rod that is parallel to said heating surface tube respectively, the external power of said rack bindiny mechanism;
It is further characterized in that: the length of said cleaning brush is less than the axial length of said heating surface tube;
Said cleaning brush inside has bristle; Said bristle be specially wire or/bulk structure that wire is formed; Said power syndeton specifically comprises toothed chain drive mechanism, external power source;
Said toothed chain drive mechanism is specially two chain drive-belts, travelling gear, power transmission shaft; Said travelling gear is installed on the two ends of said guide rod; Article two, said chain drive-belt lays respectively at the axial both sides of said heating surface tube; Article two, said chain drive-belt is connected with a joggle with the said travelling gear that is positioned at axial the same side of said heating surface tube respectively, and the middle part of said chain drive-belt connects said rack top, and an end of said chain drive-belt connects weight; The other end of said chain drive-belt connects external power source, and two travelling gears that are positioned at same horizontal plane and are positioned at rack the same side connect through power transmission shaft;
The two ends of said guide rod are equipped with the gear installation shaft, and said travelling gear is set in said gear installation shaft;
Said power source is specially hoist engine, and it is through the PLC controls of digital operation operation electronic system.
After adopting said structure of the present invention; Because said heating surface tube periphery is set with cleaning brush, the interior shape in said cleaning brush cross section and the periphery of said heating surface tube coincide, and said cleaning brush interconnects through connecting rod and forms a whole; Said connecting rod outermost end is connected in rack; Four jiaos of said rack are installed on the axial arranged guide rod that is parallel to said heating surface tube respectively, and the external power of said rack bindiny mechanism drives said rack along the translation of guide rod direction through bindiny mechanism; Drive said cleaning brush said heating surface tube axially on translation; Because the interior shape in said cleaning brush cross section and the periphery of said heating surface tube coincide, so said cleaning brush can be accomplished the cleaning to the particle dust that said heating surface tube periphery caking property is high, adsorptivity is big, in addition; Because said cleaning brush inside has bristle; Said bristle be specially wire or/bulk structure that wire is formed, it can clean the particle dust that said heating surface tube periphery caking property is high, adsorptivity is big better, thereby guarantees the heat exchange efficiency of boiler heating surface.
(4) description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of specific embodiment of the present invention.
(5) specific embodiment
See Fig. 1, Fig. 2; It comprises the heating surface tube 1 of horizontal arrangement, and heating surface tube 1 periphery is set with cleaning brush 2, and the interior shape in cleaning brush 2 cross sections and the periphery of heating surface tube coincide; Cleaning brush 2 interconnects through connecting rod 3 and forms a whole; Connecting rod 3 outermost end are connected in rack 4, and four jiaos of rack 4 are installed on the axial arranged guide rod 5 that is parallel to heating surface tube 1 respectively, the external power of rack 4 bindiny mechanism; The length of cleaning brush 2 is less than the axial length of heating surface tube 1; Cleaning brush 2 inside have bristle 6; Bristle 6 be specially wire or/bulk structure that wire is formed; The power syndeton specifically comprises toothed chain drive mechanism, external power source; The toothed chain drive mechanism is specially two chain drive-belts 7, travelling gear 8, power transmission shaft 9; Travelling gear 8 is installed on the two ends of guide rod 5; Article two, chain drive-belt 7 lays respectively at the axial both sides of heating surface tube 1; Article two, chain drive-belt 7 is connected with a joggle with the travelling gear 8 that is positioned at axial the same side of heating surface tube 1 respectively, and the middle part of chain drive-belt 7 connects rack 4 tops, and an end of chain drive-belt 7 connects weight 10; The other end of chain drive-belt 7 connects external power source, and two travelling gears 8 that are positioned at same horizontal plane and are positioned at rack 4 the same sides connect through power transmission shaft 9; The two ends of guide rod 5 are equipped with gear installation shaft 11, and travelling gear 8 is set in gear installation shaft 11; Power source is specially hoist engine 12, and it is through the PLC controls of digital operation operation electronic system.
