Abstract
The utility model relates to an airtight access door for dust collectors. The access door comprises a door body, a box flange plate, an access door press block and rubber seal strips, the door body is provided with a flange plate, the box flange plate is in contact with the door body, the access door press block is arranged outside the door body, and the rubber seal strips are used for filling the contact gap between the door body and the box flange plate. The access door is characterized in that: the box flange plate is of a double-layered structure, and a door body or box flange plate corner is of a circular arc-shaped structure. Compared with the prior art, the technique ensures that the door body can be in more sufficient contact with a box, enhances the tightness of the door body, and can help to decrease the air leakage rate.
Description
Technical field
The utility model relates to cleaner, is specifically related to a kind of deduster sealing access door.
Background technology
Domestic sack cleaner all requires air leak rate of air curtain greatly the influence of deduster to be mainly contained in≤2%. air leak rate of air curtain: thereby if 1, the deduster air leak rate of air curtain of negative-pressure operation is got over senior general cause the dedusting fan air quantity to increase energy consumption increasing the flue gas that the .2 deduster handles and have uniform temperature and contain certain moisture and corrosive gas, air leak rate of air curtain is got over senior general and is caused flue-gas temperature to reduce and dewfall is stuck with paste bag and etching apparatus body; If contain easily right, explosion hazard gases such as CO in 3 smoke treatment, air leak rate of air curtain is got over senior general and is caused deduster to have the hidden danger of blast.Cause above bad influence to take a broad view of the deduster self structure to air leak rate of air curtain, apparatus body is steel plate and section bar is welded, and needs only each weld weld seam for apparatus body and can guarantee that its air leak rate of air curtain of sealing is zero substantially.There is the access door place that need often open to have the phenomenon of leaking out only.Therefore, the sealing property of access door is the key that influences the sack cleaner air leak rate of air curtain.
At present, domestic all deduster access doors all adopt the sealing means that adhering and sealing adhesive tape pressurizing block compresses on the access door.The shortcoming of this kind mode mainly contains: 1, sealing joint strip is to be bonded on the door, because of bonding not firm or agingly easily come off; 2, be difficult for fitting tightly fully at flex point place, four right angles of access door sealing joint strip; 3, flex point place, four right angles of access door flanged plate often is difficult to guarantee flatness and sealing when welding, and pit appears in the big place, four right angles of flanged plate that may cause of welding current.Above factor is the main cause that has caused the access door air leak rate of air curtain to exceed standard.
The utility model content
At above technical problem, the utility model discloses a kind of deduster sealing access door.This has excellent sealing ability.
Its technical scheme is specifically:
This access door comprises door body with flanged plate, with the contacted casing flanged plate of this body, be located at the external access door briquetting of door and be used to fill the sealing joint strip of Men Tiyu casing flanged plate contact gap.It is characterized in that described casing flanged plate is a double-decker, described door body flanged plate flex point place is arc structure.Make contacting of a body and casing more abundant, strengthened the tightness of door body, help reducing air leak rate of air curtain.
Described sealing joint strip directly closely bonds on the casing flanged plate, and the contact zone that forms circular arc docks with described door body flanged plate flex point place.45 angles overlap joint is adopted in the sealing joint strip junction, helps reducing interface, makes contact-making surface more smooth, reduces contact gap.
With respect to prior art, advantage of the present utility model is: the seal degree height of access door, air leak rate of air curtain is lower, and simple in structure.
Description of drawings
Fig. 1 is existing deduster sealing access door structural representation.
Fig. 2 is the structural representation of the utility model preferred embodiment.
Fig. 3 is the overlapping mode schematic diagram of present embodiment sealing joint strip.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment is the same with existing deduster sealing access door, comprise a body 1, with this body 1 contacted casing flanged plate 2, be located at the outer access door briquetting 3 of a body 1 and be used to fill the sealing joint strip 4 of a body 1 and casing flanged plate 2 contact gaps.But present embodiment has been done improvement at some structure of existing deduster sealing access door, the casing flanged plate 2 of present embodiment adopts double-decker, it is arc transition that door body flanged plate flex point place 11 changes existing right angle, sealing joint strip 4 directly closely bonds on casing flanged plate 2, and the contact zone 41 that forms circular arc docks with described door body flanged plate flex point place 11.
As shown in Figure 3,45 angle mitereds are adopted in sealing joint strip 41 and 42 junctions.
Claims (3)
1. a deduster seals access door, comprise door body with flanged plate, with the contacted casing flanged plate of this body, be located at the external access door briquetting of door and be used to fill the sealing joint strip of Men Tiyu casing flanged plate contact gap, it is characterized in that, described casing flanged plate is a double-decker, and described door body flanged plate flex point place is arc structure.
2. access door as claimed in claim 1 is characterized in that, described sealing joint strip directly closely bonds on the casing flanged plate, and the contact zone that forms circular arc docks with described door body flanged plate flex point place.
3. access door as claimed in claim 1 or 2 is characterized in that, the miter angle overlapping mode is adopted in described sealing joint strip junction.
