Description
Technical field
The utility model relates to dust guard pollution abatement equipment manufacturing technology field, especially a kind of casing access door of the bag collector for cement producing line.
Background technology
Bag collector is that a kind of porous fibre filter bag that utilizes is by the dust collection device out of the dust-filtering in gas, the casing of bag collector requires airtight and load onto filter bag in casing, dusty gas enters the casing bag filtration after filtration of dust-precipitator from dust-precipitator air inlet, dusty gas is discharged through exhaust outlet through filter bag, grit is retained to amass by filter bag and cleanedly behind filter bag surface to get off, and reaches the object of purifying exhaust air.For ease of cleaning or maintenance, the casing top of dust-precipitator is all provided with multiple manhole access door.The access door of the bag collector of existing a kind of cement producing line as shown in Figure 1, comprise doorframe 10, be fixed on the manhole door closure 40 on this doorframe 10, this manhole door closure 40 has the cover plate that edge is bent to form bending edges downwards, the holddown groove coordinated with doorframe 10 is provided with at manhole door closure 40 inner face, holddown groove is by the bending edges of manhole door closure 40 and is welded on the square groove that manhole door closure 40 inner face surrounds with this bending edges, sealing ring 60 is provided with in this holddown groove, the bolt 30 that each manhole door closure 40 is all provided with by the casing 50 of bag collector and press strip 20 are locked.Because bag collector major part is outdoor layout, by the effect of such environmental effects and operating temperature, the sealing ring be arranged in holddown groove just there will be aging crisp hard, sealing variation phenomenon in use for some time, needs often to open manhole door closure and overhauls; In addition, during bag collector work under the effect of dust collecting exhaust blower, be a kind of negative pressure state in its casing.The access door of existing this bag collector exists following not enough in inspection and maintenance process: due to when opening manhole door closure and carrying out maintenance and again lock, there is the situation of leaking out in manhole door closure and doorframe fastening place tend, when running into rainy, rainwater can along manhole door closure bending edges plate to dirty, although most of rainwater can be discharged along with the inclined-plane at bag collector casing top, but still have a small amount of water can be seeped into the bottom of manhole door closure bending edges plate inner surface, owing to being a kind of negative pressure state in its casing when bag collector works, the rainwater be now seeped into bottom manhole door closure bending edges plate inner surface can be inhaled in the casing of dust-precipitator, filter bag in casing is got wet, cause bag collector cisco unity malfunction, thus affect the production of whole production line.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bag collector access door, and it can solve the problem of existing bag collector access door water resistance difference.
In order to solve the problem, the technical scheme that the utility model adopts is: this bag collector access door, comprise the doorframe being fixed on dust-precipitator casing top manhole opening part, described doorframe is provided with door closure, described door closure has the cover plate that edge is bent to form bending edges downwards, described cover plate inner face is provided with the holddown groove coordinated with described doorframe, sealing ring is provided with in described holddown groove, described cover plate is waterproof water conservancy diversion cover plate, the inner face of described waterproof water conservancy diversion cover plate is provided with Internal baffle and outer baffle, it is cavity between described outer baffle and described bending edges, described outer baffle, the inner face of Internal baffle and described waterproof water conservancy diversion cover plate encloses and forms described holddown groove.
In the technical scheme of above-mentioned bag collector access door, technical scheme can also be more specifically: the height of described bending edges is greater than the height of described outer baffle.
Further, described doorframe is by the closed framework of welding starting point limit and terminal limit after elongate steel plate bending and being formed.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, owing to having set up cavity between the holddown groove outer baffle and downward bending limit, waterproof water conservancy diversion cover plate edge of waterproof water conservancy diversion cover plate inner face, this cavity is annular cavity seal area, and the bending edges height of waterproof water conservancy diversion cover plate is greater than the height of holddown groove outer baffle, annular cavity seal area is atmospheric area, play better waterproof action, when the rainy day works, the gas containing rain can be avoided to be inhaled in dust-precipitator casing.
2, structure is simple, and cost of manufacture is low, good seal performance, is convenient to attendant and changes the service works such as the sack of dust-precipitator casing.

Fig. 1 is the structural representation of existing bag collector access door.
The structural representation of Fig. 2 embodiment of the present utility model.
Fig. 3 is the top view of the casing of embodiment of the present utility model.
Fig. 4 is the A place partial enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Bag collector access door as shown in Figures 1 to 4, comprise the doorframe 6 being fixed on dust-precipitator casing 1 top manhole opening part, doorframe 6 is provided with door closure, this door closure has edge and is bent into a 90 ° angle the cover plate forming bending edges downwards, after bending, continuous welding is carried out respectively in four arm of angle junctions, form the waterproof guide face of cover plate, cover plate inner face is provided with the holddown groove coordinated with doorframe 6, this cover plate is waterproof water conservancy diversion cover plate 4, the inner face of waterproof water conservancy diversion cover plate 4 is provided with Internal baffle 8 and outer baffle 7, be cavity 4-1 between outer baffle 7 and bending edges, outer baffle 7, the inner face of Internal baffle 8 and waterproof water conservancy diversion cover plate 4 encloses and forms above-mentioned holddown groove, be provided with sealing ring 5 in holddown groove, the height on waterproof water conservancy diversion cover plate 4 surrounding downward bending limit is greater than the height of outer baffle 7, doorframe 6 is by the closed framework of welding starting point limit and terminal limit after elongate steel plate bending and being formed, sealing ring 5 forms by bipeltate bar two ends are cementing, the clamping screw 3 that every block waterproof water conservancy diversion cover plate 4 is provided with by dust-precipitator casing 1 top and press strip fixing and locking, the grooved pressing plate 2 of this press strip to be one piece of two be arc, every block grooved pressing plate 2 is provided with the circular hole coordinated with clamping screw 3, and many clamping screws 3 are fixed by welding on the dust-precipitator casing 1 between adjacent two waterproof water conservancy diversion cover plates 4.
