Abstract
A negative pressure extracting device for a vacuum boiler comprises cooling tanks and a water-collecting tank, wherein a circulatory cooling water inlet is formed in the side surface of the lower part of the corresponding cooling tank; a circulatory cooling water outlet is formed in the side surface of the upper part of the corresponding cooling tank; outlets in the bottom of the cooling tanks are connected to inlets of the water-collecting tank through pipes; and at least one spiral pipe is arranged in the cooling tanks. Heat of high-temperature media in the spiral pipes is taken away by quick circulatory flowing of the circulatory cooling water, and an extracting opening of a vacuum pump is separated from an opening of a condensate water pipe by a steam-water separating partition in the water-collecting tank while condensate water is guided by the steam-water separating partition. Because the temperature of the media is reduced in real time, and the condensate water generated during extracting is well subjected to steam, oil and water separation, the quality and the temperature of oil products of the vacuum pump are guaranteed, and the purpose of continuously extracting negative pressure in real time without stopping is achieved.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to 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 link to each other with the import and export of cooling tank 1 respectively; The inside of described water collect tank 2 is provided with a vapour, moisture from dividing plate 9, water collect tank 2 is separated into the cavity that two bottoms communicate, offer water collect tank 2 entrances at vapour, moisture from the cavity top of dividing plate 9 one sides, offer at least one vavuum pump interface 6 on the side of opposite side cavity; 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 30 ° of inclinations angle.Be provided with stainless steel ball valve 5 on the pipeline that is connected between cooling tank 1 and the water collect tank 2.The pipeline of stainless steel ball valve 5 and connection each several part all adopts the stainless steel of SS304.
Referring to 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 links to each other with the entrance of the recirculated cooling water of second group of cooling tank; Simultaneously on the water collect tank a plurality of vavuum pump interfaces can be set as required, work simultaneously in order to connect a plurality of vavuum pumps, to increase work efficiency; The present invention also can arrange many helical pipes as required in cooling tank.
