Abstract
The utility model discloses a lower end sealing device for a water cooling vibration fire grate, and relates to the field of boiler devices. The device comprises a compaction steel plate (1), sealing insertion sheets (2), a bolt (3), a nut (4), a lock washer (5), and a connecting plate (6). The lower end sealing device is characterized in that, one end of the connecting plate (6) is welded onto a fire grate pipe (7), three upper sealing insertion sheets are in a bolt connection with the connecting plate (6), two lower sealing insertion sheets are in a bolt connection with a sealing guard board (8), the angles of the sealing insertion sheets (2) and a transmission rod (9) are the same, the upper sealing insertion sheets and the lower sealing insertion sheets (2) are in an intersected arrangement, and the sealing insertion sheets (2) are stainless steel plates. The beneficial effects of the lower end sealing device are: simple and practical structure, convenient replacing, low maintenance cost, and more reliable operation. The thin stainless steel plates are used for the sealing insertion sheets, and good elasticity and wear resistance are provided.
Description
Technical field
The utility model relates to the low side sealing device structure in boiler plant field, particularly a kind of water-cooling vibration furnace grate.
Background technology
Water-cooling vibration furnace grate boiler is widely used in biomass fuel boiler, and designing requirement fuel partical suspension burning, has relatively high expectations for wind chamber sealing.And water-cooling vibration furnace grate dither, the structural design difficulty of sealing strengthens.
Sealing device is one of critical component in water-cooling vibration furnace grate boiler combustion equipment, and its effect is to provide a good wind chamber sealing, obtains an enough air compartment blast, to guarantee the partical suspension burning requirement of fuel.Domestic water-cooling vibration furnace grate boiler, because containing a large amount of impurity in biomass fuel, original labyrinth type Seal Design, in labyrinth in service, material runs off and the entering of grey solid impurity particle, and the blowing out that results in blockage, can not meet operation steady in a long-term.
Utility model content
The purpose of this utility model is: for the problem of above-mentioned existence, provide a kind of replacing simple, convenient, the replacement cycle is short, connects reliably the low end sealing device of water-cooling vibration furnace grate that service time is long.
The purpose of this utility model realizes by following technical proposals: the low end sealing device of a kind of water-cooling vibration furnace grate, comprise and compress steel plate, sealing inserted sheet, bolt, nut, lock washer, connecting plate, connecting plate one end is welded on furnace grate tube, three sealing inserted sheets and connecting plate bolt are arranged at top, and two sealing inserted sheets and sealing backplate bolt are arranged at bottom.
Preferably, sealing inserted sheet is identical with the angle of drive link.
Preferably, upper and lower sealing inserted sheet arranged crosswise.
Preferably, sealing inserted sheet is corrosion resistant plate.
Preferably, use lock washer during each position of bolt.
The beneficial effects of the utility model: meet the vibration requirement of fire grate by the relative motion of sealing inserted sheet, multi-layer sealed inserted sheet guarantees seal request, sealing inserted sheet adopts thin corrosion resistant plate, there is good wearability, elasticity, seal inserted sheet bolt on connecting plate, and adopt lock washer to prevent coming off of bolt, nut.The utility model is simple and practical, and it is convenient to change, and maintenance cost is low, moves more reliable.Sealing inserted sheet adopts thin corrosion resistant plate, has good elasticity, wearability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 for compressing steel plate, and 2 is sealing inserted sheet, and 3 is bolt, and 4 is nut, and 5 is lock washer, and 6 is connecting plate, and 7 is furnace grate tube, and 8 is sealing backplate, and 9 is drive link.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Embodiment: as shown in Figure 1, the low end sealing device of a kind of water-cooling vibration furnace grate comprises compression steel plate 1, sealing inserted sheet 2, bolt 3, nut 4, lock washer 5, connecting plate 6.One end of connecting plate 6 is welded on furnace grate tube 7 bottoms, and the other end of brace 6 passes through bolt 3, nut 4 and sealing inserted sheet 2, compresses together with steel plate 1, lock washer 5 bolts.Be called top seal inserted sheet 2 with the three sealing inserted sheets 2 that have of connecting plate 6 bolts.Brace 6 is in bottom, and top seal inserted sheet 2, in centre, compresses steel plate 1 in the above.Sealing inserted sheet 2 adopts the good thin corrosion resistant plate of elasticity, seals inserted sheet 2 and keep equal angular with drive link 9 during installation, guarantees the bending amplitude of sealing inserted sheet 2 minimums.There are two sealing inserted sheets 2 to be called lower seal inserted sheet 2 with sealing backplate 8 bolts, upper and lower sealing inserted sheet 2 arranged crosswise, multi-layer sealed.By the relative motion of sealing inserted sheet 2, meet the vibration requirement of fire grate, multi-layer sealed inserted sheet 2 guarantees seal request.Lower seal inserted sheet 2 is in centre, and bottom is sealing backplate 8, compresses steel plate 1 in the above, and bolt 3 and nut 4 come bolt sealing backplate 8, sealing inserted sheet 2, compress steel plate 1, lock washer 5.Adopt lock washer 5 to prevent that bolt 3, nut 4 from coming off.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
