Abstract
The utility model provides a desilting door device for large-scale storage tank, is equipped with the desilting mouth on the storage tank body, be equipped with the flange on the desilting mouth, the tip of flange is equipped with the blind flange, the blind flange is connected with the rotatory davit that is located desilting mouth one side. The utility model discloses a set up rotatory davit, when carrying out the desilting during operation, hoist the blind flange through rotatory davit, make things convenient for staff's entering and portable clearance instrument.
Description
Technical Field
The utility model relates to a large-scale storage tank especially relates to a desilting door device for large-scale storage tank.
Background
The large-scale storage tank can remain some impurities such as silt in the tank bottom owing to store the material for a long time, and the time is longer, and accumulational more, sets up the impurity such as silt that the hole was regularly cleared up the tank bottom at the tank bottom usually.
CN203006988U discloses a cleaning hole with a drainage pipe for a sewage treatment tank, which achieves the dredging purpose by welding a cleaning hole flange at the outer side of a hole neck and welding a drainage pipe under a reinforced bottom plate. But this cleaning hole aperture is less, and the clearance personnel need bore into and just can clear up to carry the clearance instrument comparatively difficult, and this application is through setting up the handle pulling flange lid on the flange lid, make the work of desilting waste time and energy, intensity of labour is high, work efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome the above-mentioned defect that prior art exists, provide a low in labor strength, labour saving and time saving's desilting door gear for large-scale storage tank.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a desilting door device for large-scale storage tank, is equipped with the desilting mouth on the storage tank body, be equipped with the flange on the desilting mouth, the tip of flange is equipped with the blind flange, the blind flange is connected with the rotatory davit that is located desilting mouth one side.
Further, the rotary suspension arm is connected with the flange cover through a bolt fastener.
Furthermore, the desilting mouth welds with tank bottoms reinforcing plate, jar wall reinforcing plate and reinforcing plate on the storage tank body respectively.
Further, a sewage draining connecting pipe is arranged at the bottom of the flange cover.
The utility model discloses a set up rotatory davit, when carrying out the desilting during operation, hoist the blind flange through rotatory davit, make things convenient for staff's entering and portable clearance instrument.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a cross-sectional view taken at A-A in the embodiment shown in FIG. 1.
In the figure: 1. the tank bottom reinforcing plate 2, the tank wall reinforcing plate 3, the tank body reinforcing plate 4, the rotary suspension arm 5, the first bolt 6, the desilting opening 7, the flange 8, the flange cover 9, the sewage discharge connecting pipe 10 and the second bolt.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, this embodiment sets up desilting mouth 6 on the storage tank body, desilting mouth 6 is the large-size long circular port of seting up on jar wall reinforcing plate 2 and jar body reinforcing plate 3, desilting mouth 6 outwards extends and forms the oral neck, the oral neck respectively with tank bottoms reinforcing plate 1, jar wall reinforcing plate 2 and jar body reinforcing plate 3 welding, welding flange 7 is gone up to the oral neck, the bottom and the tank bottoms reinforcing plate 2 welding of flange 7, flange 7 is connected with flange cover 8 through second bolt 10, flange cover 8 is as the desilting door, 9 welding in the bottom of flange cover 8 are taken over in the blowdown, flange cover 8 is connected through first bolt 5 with the rotatory davit 4 that is located desilting mouth 6 one side.
The large-size dredging door is adopted, so that cleaning tools and sludge can be conveyed by the cart from the dredging door, and personnel can conveniently enter and exit from the dredging door; through setting up rotatory davit, can make the blind flange that the law is heavier nimble open and close.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
