Description
Technical field
The utility model relates to dedusting sealing configuration wherein, is specifically related to the sealing configuration on a kind of deduster casing.
Background technique
The pulse bag type dust collector that uses in the modern industry; Be made up of several parts such as upper box, middle casing, ash bucket, ash discharging system, injection system and control system, and air inlet divides cell structure under adopting, ash-laden gas gets into ash bucket by lower box in the intake grill warp; The grit that wherein part is bigger is because effects such as inertial collision, natural subsidence directly fall into ash bucket; Other grit rises with air-flow and gets into each bag chamber, and after filter bag filtered, grit was delayed at the filter bag outside; Purified gas enters atmosphere through off-line valve, exhaust outlet again by the inner upper box that gets into of filter bag.Be deposited in the ash bucket dust regularly or draw off by screw conveyor and rigidity impeller discharger continuously.Along with constantly carrying out of filter process, the appended long-pending dust in the filter bag outside constantly increases, and causes the resistance of sack cleaner itself also to raise gradually; When resistance reached preset value, the deashing controller sent signal, at first made the off-line valve of a bag chamber close; Cut off the overanxious air-flow of this chamber, open electromagnetic impulse valve then, the nozzle of pressurized air order on gas bag, sentinel valve, winding-up pipe sprays to filter bag; Pressurized air expands at a high speed in case, makes filter bag produce the dither distortion, adds the effect of inverted draft; The dirt cake distortion that the filter bag outside is adhered to comes off, and after the sedimentation time that has taken into full account dust, the off-line valve is opened; This bag chamber filter bag returns to the filtration state, and next bag chamber then gets into the deashing state.For the ease of to overhauling and clear up dust in the upper box, generally can access hole be set on upper box, hatch door is installed on access hole.In order to prevent that dust, flue gas from being escaped out by the access hole place, as shown in Figure 1 in the prior art, will between hatch door and access hole, add Stamping Steel Ribbon.But, find that in actual use also having some dusts, flue gas escapes out in the access hole place thus because existing Stamping Steel Ribbon is the sealing configuration of single-layer type.Therefore be necessary the sealing configuration between existing hatch door and the access hole is improved.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, provides a kind of simple in structure, good sealing effect, the sealing configuration on the deduster casing that is easy to process, be easy to install and use.
For realizing above-mentioned purpose; The technological scheme of the utility model is the sealing configuration on a kind of deduster casing of design, it is characterized in that described sealing configuration comprises access hole and the hatch door on the deduster casing; One side spiral-lock of said hatch door is in access hole; On said access hole, be provided with frame, on said frame, be provided with first annular sealing strip, the cross section of said first annular sealing strip is a length of side, the first short U-groove bevel of one side; The base of said first U-groove bevel closely is connected with said frame, in said first U-groove bevel, sealing material is housed; On said hatch door, be provided with the doorframe that extends to the access hole outer and match with said frame; Said doorframe is provided with and corresponding second annular sealing strip in the first annular sealing strip position in the side in the face of frame; The cross section of said second annular sealing strip is a length of side, the second short U-groove bevel of one side, and the installation direction of said second U-groove bevel and first U-groove bevel is opposite; Wherein, the long limit of said first U-groove bevel is crimped on the sealing material in second U-groove bevel, and the long limit of said second U-groove bevel is crimped on the sealing material of first U-groove bevel, constitutes the double sealing structure on the access hole thus.
For simplified structure, and have good sealing effect, as optimized technical scheme be, described sealing material is a rubber weather strip.
For the ease of installing and using and beautiful shape; Further optimized technical scheme is; Minor face at the above first U-groove bevel of said access hole is arranged on the side near access hole, is arranged on outer rim one side of said doorframe at the minor face of the above second U-groove bevel of said hatch door.
For the ease of hatch door is fixed on the access hole; And easily hatch door is opened during easy access again; Comprise also that as optimized technical scheme on said frame, also be provided with fastener bracket, said fastener bracket is arranged on the outside of said first annular sealing strip; On said hatch door, be provided with buckling piece, the link of bolt, nut or clamping-type is housed between said fastener bracket and said buckling piece.
For the ease of hatch door is fixed on the access hole; And easily hatch door to be opened further optimized technical scheme during easy access again be between said frame and said hatch door, to be evenly equipped with the link of several fastener bracket, buckling piece and bolt, nut or clamping-type.
The advantage and the beneficial effect of the utility model are: because original access hole only is equipped with Stamping Steel Ribbon on hatch door, on the frame of access hole, do not have Stamping Steel Ribbon, belong to single sealing configuration.And after the utility model improvement, except on hatch door, being equipped with the Stamping Steel Ribbon.On the frame of access hole, also install Stamping Steel Ribbon additional.When the hatch door and the frame of access hole closely compress with hold-down bolt combine after, can realize double-sealing, the leakage of flue dust is almost equal to zero.Advantages such as this structure also has simple in structurely simultaneously, is easy to processing, is easy to install, and is easy to use.
