Abstract
The utility model discloses an anti-seep cast iron sealed chamber cover for sewage treatment equipment. The thread line of the anti-seep cast iron sealed chamber cover is in fillet transition to form a main body of a sealed chamber cover; and the fillet is positioned on the thread line and distributed along the circumference of the whole sealed chamber, and two vertical long and short right-angle sides of the fillet are in smooth transition. By combining the cast formation theory, the right-angle on the thread line of the sealed chamber cover is designed into a fillet smooth design, and distributed along the circumference of the whole sealed chamber cover to eliminate sharp angles, so that shrinkage and seepage on the position in the casting process can be prevented.
Description
Technical field
The utility model is particularly related to a kind of sewage disposal device and seals chamber cap with antiseep cast iron.
Background technology
Along with the fast development of industry, the requirement of sewage disposal device is also more and more higher, reduces the leakage of sewage in treating processes, is to improve sewage treating efficiency, improves service life of equipment, one of means of environmental contamination reduction.And the defective owing to the sealing chamber cap accounts for more than 10% in total leakage.For preventing the sealing cover seepage, usually need frequent sealing chamber cap, cause equipment downtime, and maintenance cost is higher.The thread position of general sealing cover chamber all belongs to right-angle design, forms wedge angle, and the solidification sequence to molten iron in castingprocesses has a negative impact, and forms the casting thermal center, produces easily shrinkage porosite and causes seepage.
Summary of the invention
Goal of the invention: in order to solve the shrinkage porosite leakage problems that the conventional seals lid exists in the above-mentioned background technology, provide a kind of sewage disposal device to seal chamber cap with antiseep cast iron.
The technical scheme that adopts: a kind of sewage disposal device seals chamber cap with antiseep cast iron, and its thread 2 places adopt fillet 3 transition, consists of the main body 1 of sealing chamber cap; Fillet 3 is positioned at thread 2 places and along whole sealing chamber cap circumference, and fillet 3 sizes and vertical two square edge 4 smooth transition.
Beneficial effect: theoretical in conjunction with casting, the right-angle design that the utility model will seal the thread place of chamber cap changes the smooth design of fillet into, along whole sealing chamber cap circumference, eliminates wedge angle, thereby solves the shrinkage porosite seepage of this position in the castingprocesses.
Description of drawings
Fig. 1 is a kind of sewage disposal device of the utility model seals chamber cap with antiseep cast iron sectional view.
Embodiment
