Technical field
The invention belongs to vacuum equipment manufacture, maintaining field, relate to the device that a kind of vacuum equipment extracts negative pressure, especially a kind of vacuum boiler extracts negative pressure device.
Background technology
Vacuum boiler is in the manufacturing and later stage regular maintenance, in servicing operations, need regularly vacuumize equipment, make furnace atmosphere remain on a good negative pressure state, thus guarantee the normal operation of equipment high efficiency.In actual production, under vacuum boiler and other vacuum equipment furnace atmosphere remain on high-temperature high-pressure state, boiler must be shut down when maintenance, maintenance and lay down pressure and treat that furnace atmosphere and WATER AS FLOW MEDIUM etc. are down to normal temperature and can be carried out, simultaneously need special messenger's timing to release to vacuum oil to filter and supplement new vacuum oil because condensed water dissolves in vacuum pump body vacuum oil, the lower and oil product of efficiency waste comparatively Datong District time larger to Influence of production; Because maintenance downtime causes inefficiency, also there is no direct under the continuous working order of vacuum equipment, carry out extracting negative pressure technology and equipment at present.
Summary of the invention
The object of the invention is to solve the problem, provide a kind of vacuum boiler to extract negative pressure device, high-temperature medium heat is taken away by cooling circulating water by this device, thus reaches the object of fast cooling; Vavuum pump extraction opening and the condensed water mouth of pipe separate while condensate water guide by water collect tank dividing plate, thus ensure that oil quality and temperature rise normally improve extraction efficiency; Owing to reducing the temperature of medium in real time and the condensed water produced when extracting well having been carried out vapour, oil, water separation, pumping fluid quality and temperature are guaranteed, reach the object of not shutting down continuous drawing negative pressure in real time.
The object of the invention is to solve by the following technical programs:
A kind of vacuum boiler extracts negative pressure device, comprises cooling tank and water collect tank; The lower side of described cooling tank offers circulating cooling water inlet, and upper side offers circulating cooling water out; Described cooling tank outlet at bottom is connected to the entrance of water collect tank by pipeline; The inside of described cooling tank is provided with at least one helical pipe, and its two ends are connected with the import and export of cooling tank respectively; The inside of described water collect tank is provided with one block of vapour, water is separated dividing plate, water collect tank is separated into the cavity that two bottoms communicate, offer water collect tank entrance at the cavity top of vapour, water separation dividing plate side, the side of opposite side cavity offers at least one vacuum pump interface; The bottom of described water collect tank has condensate drain outlet.
The negative pressure extracting mouth of the external vacuum equipment of entrance at above-mentioned cooling tank top.
Above-mentioned vacuum equipment is vacuum boiler.
Above-mentioned helical pipe is 30 ° of inclinations angle.
Above-mentioned cooling tank is provided with stainless steel ball valve with on the pipeline be connected between water collect tank.
The pipeline of above-mentioned stainless steel ball valve and connection each several part all adopts the stainless steel of SS304.
High-temperature medium heat in helix tube is taken away by adopting the flowing of the Rapid Circulation of recirculated cooling water by the present invention, thus reaches the object of fast cooling; In water collect tank, vapour, water are separated dividing plate and vavuum pump extraction opening and the condensed water mouth of pipe are separated while condensate water guide, prevent from being sucked by condensed water in pump housing vacuum oil product, thus ensure that oil quality and temperature rise normally improve extraction efficiency.Owing to reducing the temperature of medium in real time and the condensed water produced when extracting well having been carried out vapour, oil, water separation, pumping fluid quality and temperature are guaranteed, reach the object of not shutting down continuous drawing negative pressure in real time.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1-3, a kind of vacuum boiler extracts negative pressure device, comprises cooling tank 1 and water collect tank 2; The lower side of described cooling tank 1 offers circulating cooling water inlet 3, and upper side offers circulating cooling water out 4; Described cooling tank 1 outlet at bottom is connected to the entrance of water collect tank 2 by pipeline; The inside of described cooling tank 1 is provided with at least one helical pipe 8, and its two ends are connected with the import and export of cooling tank 1 respectively; The inside of described water collect tank 2 is provided with one block of vapour, water is separated dividing plate 9, water collect tank 2 is separated into the cavity that two bottoms communicate, offer water collect tank 2 entrance at the cavity top of vapour, water separation dividing plate 9 side, the side of opposite side cavity offers at least one vacuum pump interface 6; The bottom of described water collect tank 2 has condensate drain outlet 7.The negative pressure extracting mouth of the external vacuum equipment of entrance at cooling tank 1 top.Vacuum equipment is vacuum boiler.Helical pipe 8 is in 30 ° of inclinations angle.The pipeline be connected between cooling tank 1 with water collect tank 2 is provided with stainless steel ball valve 5.The pipeline of stainless steel ball valve 5 and connection each several part all adopts the stainless steel of SS304.
See Fig. 1 and 2, the present invention can arrange the cooling tank that two cover recirculated cooling waters are in series as required, and namely the circulating cooling water out of first group of cooling tank is connected with the entrance of the recirculated cooling water of second group of cooling tank; Simultaneously as required water collect tank can arrange multiple vacuum pump interface, work, to increase work efficiency in order to connect multiple vavuum pump simultaneously; The present invention also can arrange many helical pipes as required in cooling tank.
Originally be that embodiment selects two cover cooling tanks, and in each cooling tank, be provided with two groups of helical pipes, water collect tank is provided with the optimum way of two vacuum pump interface.High-temperature medium enters the helical pipe two cooling tanks from vacuum boiler simultaneously, and helical pipe surrounds by recirculated cooling water, is taken away by high-temperature medium heat in helix tube, thus reach the object of fast cooling by the Rapid Circulation flowing of recirculated cooling water; The condensed water that period produces flows into water collect tank with pipeline, and is separated along vapour, water the bottom that dividing plate concentrates on water collect tank, finally discharges tank body from condensate drain outlet.Use while two groups of vavuum pumps simultaneously, improve operating efficiency, in water collect tank, vapour, water are separated dividing plate and vavuum pump extraction opening and the condensed water mouth of pipe are separated while by condensate water guide, prevent from condensed water being sucked in pump housing vacuum oil product, thus ensure that oil quality and temperature rise normally improve extraction efficiency.Owing to reducing the temperature of medium in real time and the condensed water produced when extracting well having been carried out vapour, oil, water separation; pumping fluid quality and temperature are guaranteed; reach the object of not shutting down continuous drawing negative pressure in real time; make vavuum pump operationally non-maintaining continuous real-time working again; eliminate in original technology the shortcoming needing to shut down, lower the temperature and need arrange special messenger's filter replacement pumping fluid, drastically increase the operating efficiency extracting negative pressure.
