Abstract

The utility model discloses an access door of an ash bucket of a dust collector, which comprises a door frame (1) installed on a wall plate (6) of the ash bucket of the dust collector, a door cover (2) connected on the door frame (1), as well as a hinge (2), a rotating bolt (4) and a handle (5) connected on the door cover (2), and is characterized in that a rectangular box body (7) is fixed on the inner side of the door cover (2). As the rectangular box body is only fixed at the inner part of the door cover of the access door of an existing ash bucket, the accumulation of alumina freely flowing downwards in a groove in the access door of the ash bucket can be effectively prevented; thus, the problem of serious leakage of the alumina when the access door of the dust collector for electrolysis and purification is opened is effectively solved; therefore, the access door has the advantage of completely preventing the accumulation of materials at the inner part of the access door of the ash bucket of the dust collector, and thus the occurrence of alumina leakage when the access door is opened can be effectively avoided.

Description

The dust collector ash hopper access door

Technical field

The utility model relates to a kind of dust collector ash hopper access door, belongs to the deduster technical field.

Background technology

The dust collector ash hopper access door is mounted on the sidewall paneling of dust collector ash hopper, is used for the sealed door of repair apparatus, can realize fast opening and closing, and good seal.After the sack cleaner card installs, be the passage of unique turnover deduster box house.Filter bag must enter in the deduster by access door and pick up fall into ash bucket in installation, running after.Meet tide at aluminium oxide and harden and become block, in the time of can't discharging from the ash bucket bottom, must enter artificial removing in the ash bucket.The ash bucket of existing sack cleaner is a conical design, and 〉=60 ° of ash bucket bucket shape and the designs of the horizontal angle of cut are to guarantee freely flowing downward of aluminium oxide.The ash bucket of electrolysis flue gas purifying dust-removing device is different from the ash bucket of common deduster, must store a certain amount of aluminium oxide in the ash bucket, be transported to deduster inlet airduct from ash bucket once more as adsorbent, participate in the adsorption reaction of HF gas in the flue gas, so alumina concentration height in the electrolysis flue gas purifying dust-removing device ash bucket, the ash amount is big.At present, existing dust collector ash hopper access door ubiquity the alumina powder that the filter bag ash removal on access door top falls and can be piled up (as shown in Figure 1) below access door, when at every turn when external opening is opened access door soon, its mobile well aluminium oxide can trickle rapidly to deduster inspection platform and ground, causes the loss of Aluminum Electrolysis Production raw material and pollutes working environment.Therefore, the result of use of existing dust collector ash hopper access door still is not ideal enough.

Summary of the invention

The purpose of this utility model is: provide a kind of and can avoid the inner dust collector ash hopper access door of piling up material fully, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: a kind of dust collector ash hopper access door of the present utility model, comprise the doorframe that is installed on the dust collector ash hopper sidewall paneling, and be connected the door closure on the doorframe and be connected hinge, swivel bolt and handle on the door closure, on the inboard of door closure, be fixed with a rectangular box.

Less than the length and the wide size of doorframe, the bottom surface of rectangular box is equal to or greater than the height of the inner surface of dust collector ash hopper sidewall paneling to the door closure medial surface to the height of door closure medial surface respectively for the length of above-mentioned rectangular box and wide size.

Owing to adopted technique scheme, the utility model is only in rectangular box of existing ash bucket maintenance door closure internal fixation, pile up in the groove of aluminium oxide in the ash bucket access door that so just can prevent from effectively freely to flow downward, when thereby the access door of having avoided the electrolytic cleaning dust collector ash hopper was effectively opened, its aluminium oxide leaked the serious problem of material.Therefore, the utility model compared with prior art the utlity model has and can prevent the inner advantage of piling up material of dust collector ash hopper access door fully, thus the generation that aluminium oxide leaks can avoid access door to open effectively the time.

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with embodiment the utility model is further described.

Embodiment of the present utility model: structure of the present utility model as shown in Figure 2, the utility model can directly be implemented on existing dust collector ash hopper access door, be that dust collector ash hopper access door of the present utility model comprises the existing doorframe 1 that is installed on the dust collector ash hopper sidewall paneling 6, and be connected the door closure 2 on the doorframe 1 and be connected hinge 3 on the door closure 2, swivel bolt 4 and handle 5, during making, earlier with behind door closure 2 complete openings, on the inboard of door closure 2, adopt the iron sheet welding to fix a rectangular box 7 then, make the length of this rectangular box 7 and wide size respectively less than the length and the wide size of doorframe 1, and the bottom surface that makes rectangular box 7 inner surface that is equal to or greater than dust collector ash hopper sidewall paneling 6 to the height h of door closure 2 medial surfaces is to the height H of door closure 2 medial surfaces.

Claims

1. dust collector ash hopper access door, comprise the doorframe (1) that is installed on the dust collector ash hopper sidewall paneling (6), and be connected the door closure (2) on the doorframe (1) and be connected hinge (3), swivel bolt (4) and handle (5) on the door closure (2), it is characterized in that: on the inboard of door closure (2), be fixed with a rectangular box (7).

2. dust collector ash hopper access door according to claim 1, it is characterized in that: less than the length and the wide size of doorframe (1), the bottom surface of rectangular box (7) is equal to or greater than the height (H) of the inner surface of dust collector ash hopper sidewall paneling (6) to door closure (2) medial surface to the height (h) of door closure (2) medial surface respectively for the length of rectangular box (7) and wide size.
