Description
Technical field
The utility model relates to alcohol ketone process units, particularly a kind of reconstruction structure of blue formula filter of the centrifugal pump for alcohol ketone process units.
Background technique
Multiple centrifugal pump filter is had in prior art, such as a kind of centrifugal pump venting oil filling filter device (please refer to Fig. 2) disclosed in Chinese patent CN203023145, comprises the modular constructions such as filtering cover 1a, filtering plug 2a, filter screen 3a, oil inlet passage 4a, bleed passage 5a.
For alcohol ketone process units, centrifugal pump filter need be used equally.Now a sewage draining exit is generally only had with centrifugal pump filter in alcohol ketone production process.And alcohol ketone process units is generally regular carries out window maintenance, need the capable cleaning of filter therebetween, if the window repair time is long or the Cleaning period is long, is easy to cause filter sewage draining exit to block, can not clears up in time, filter normally can not play filtration, have a strong impact on normal operation and the performance of centrifugal pump, reduced equipment availability and utilization ratio, time serious, even need therefore unplanned parking, unfavorable in production, have a strong impact on manufacturing efficiency.
Therefore, how to design a kind of reconstruction structure of the centrifugal pump filter for alcohol ketone process units, make it can solve defect of the prior art, namely become those skilled in the art's problem demanding prompt solution.
Model utility content
The purpose of this utility model is the reconstruction structure providing a kind of centrifugal pump filter for alcohol ketone process units, makes it when bottom blow-down mouth is blocked by chemical industry material, still can blowdown in time.
For achieving the above object, the utility model provides a kind of reconstruction structure of the centrifugal pump filter for alcohol ketone process units, comprising:
One housing, this housing has a upper opening and an inner space, offers a filtration fluid input and respectively and filter fluid output on this housing two side;
One cap, covers on this upper opening of this housing with by this housing seal;
One blue formula filter screen, the inner space of this housing is divided into a side to be filtered and to filter side by this blue formula filter screen, and this filtration fluid input corresponds to this side to be filtered, and this filtration fluid output corresponds to this filtration side;
One first sewage draining exit, is opened in this shell bottom wall; And
One second sewage draining exit, is opened in below this housing sidewall.
Wherein, in reconstruction structure one better embodiment of the centrifugal pump filter for alcohol ketone process units of the present utility model, this cap offers a relief hole.
Wherein, in reconstruction structure one better embodiment of the centrifugal pump filter for alcohol ketone process units of the present utility model, this first sewage draining exit has one first valve.Thus, in filter normal working, when filter bottom detained matter is few, first sewage draining exit can be closed, direct use second sewage draining exit 5 carry out blowdown (or close the second sewage draining exit only use the first sewage draining exit to carry out blowdown, that is, not blocked and detained matter is few time only can use single drain outlet).When filter bottom detained matter runs up to certain altitude, the first sewage draining exit and the second sewage draining exit are opened simultaneously and are thoroughly cleared up.
Wherein, in reconstruction structure one better embodiment of the centrifugal pump filter for alcohol ketone process units of the present utility model, this second sewage draining exit comprises a short circuit and one second valve, this short circuit one end to be fixed in below this housing sidewall and to be communicated with this enclosure interior space, and this second valve is arranged at this short circuit the other end.Thus, when housing bottom first sewage draining exit is blocked by chemical industry material, blowdown can be carried out by the second sewage draining exit, avoid because of the first sewage draining exit blocking brings cannot the situation of blowdown.In addition, when carrying out the cleaning of blue formula filter screen, the first sewage draining exit can be cleared up simultaneously, raising the efficiency; If do not possess the condition of cleaning first sewage draining exit, also directly can substitute the first sewage draining exit with the second sewage draining exit, the cleaning of the first sewage draining exit wouldn't be carried out.
