Abstract
The utility model relates to the field of epoxypropane production apparatuses, and concretely refers to a filter-pressing slurry pump sealing cooling water apparatus. The apparatus comprises a cooling water storage apparatus, a circulating water pump and slurry pumps, wherein the circulating water pump is a horizontal-type chemical centrifugal pump, and circulating cooling systems are formed by the cooling water storage apparatus, the horizontal-type chemical centrifugal pump and sealing systems of the slurry pumps. According to the apparatus provided by the utility model, the horizontal-type chemical centrifugal pump is used to replace a conventional pipeline booster pump to provide seal flushing water for each slurry pump of the filter-pressing positions, thereby increasing operation cycles, reducing maintenance loads, and ensuring long-term and stable operation of a press filtration system.
Description
Technical field
The utility model relates to a kind of filter-press residues stock pump sealing chilled water unit in production of propylene oxide field.
Background technique
Epoxypropane workshop press filtration post is provided with many slag stock pumps, its sealing system is fetched water from water storage box by blower pump for pipeline and is washed cooling, blower pump for pipeline is generally vertical pump, impeller is by two dish bearing suspensions, bearing in service very easily damages, maintenance load is large, and affects the normal operation of press filtration work.
The model utility content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of reasonable in design, long service life, filter-press residues stock pump sealing chilled water unit that maintenance load is little are provided.
Its technological scheme is: comprise chilled water storage device, circulating water pump and slag stock pump, described circulating water pump is the Horizontal chemical engineering centrifugal pump, and the sealing system of chilled water storage device, Horizontal chemical engineering centrifugal pump and slag stock pump forms circulating cooling system.
The utility model has reduced maintenance load by replace vertical blower pump for pipeline to unify to increase the operation period for sealflushing water to each slag stock pump of press filtration post with the Horizontal chemical engineering centrifugal pump, guarantees press filteration system operation steady in a long-term.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of filter-press residues stock pump sealing chilled water unit, chilled water tank 1 connects Horizontal chemical engineering centrifugal pump 2 by pipeline, its outlet line 3 connects a plurality of take-off lines, each take-off line connects respectively at the mechanical sealing system cooling water intake of every slag stock pump 5, the mechanical sealing system coolant outlet of every slag stock pump 5 all is connected with reflux pipeline 4, and namely the mechanical seal cooling system of every slag stock pump 5 is all set up circulating cooling system with chilled water tank 1, Horizontal chemical engineering centrifugal pump 2.
