Vacuum feed bin is mutually abutted against.
The beneficial effects of the utility model:As a result of said structure, because the charging aperture of vacuum feed bin is located at thereon
Portion, the slurry into vacuum feed bin has the process that freely drops and hit, this process during pump housing charging aperture is reached
Complete under vacuum conditions so that the air bubble expansion in slurry ruptures and discharged, the gas of release is siphoned away by vavuum pump, from
And make it that the slurry for entering the pump housing eliminates bubble, realizes the exhaust purpose of slurry, slurry is stirred mixed process in early stage
In the bubble that is mixed into eliminated before pumping, be effectively improved the quality of slurry.The device can not only stir traditional mixer
Slurry in bubble eliminate, also can ensure that secondary will not be mixed into bubble before pouring, simple and reliable for structure.

Fig. 2 is the structural representation that rotor segment device is carried in the utility model vacuum feed bin.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1 of the present utility model is as shown in figure 1, a kind of exhaust installed in slurry pump housing front end of the present utility model
Device, it is characterised in that including vacuum feed bin 2, open type feed bin 3, suction tube 4, opening and closing valve 5, vavuum pump 6, described vacuum material
Storehouse 2 is closed vessel, and is arranged on the top of pump housing charging aperture 7, is entered on the top of described vacuum feed bin provided with vacuum feed bin
Material mouth 8 and bleeding point 9, are provided with the bottom of described vacuum feed bin and seal the discharging opening 10 connected with pump housing charging aperture 7, in institute
The side for the vacuum feed bin 2 stated is provided with the open type feed bin 3 for being used for storing stirring mixing disposed slurry, and described open type feed bin is top
Unlimited container, discharging opening is provided with the bottom of the open type feed bin, and the discharging opening passes through suction tube 4 and vacuum feed bin top
Vacuum feed bin charging aperture 8 is connected, provided with opening and closing valve 5 on described suction tube 4, and the liquid level that open type feed bin contains slurry is high
Degree is less than the height of vacuum feed bin top vacuum feed bin charging aperture 8, to ensure that slurry will not flow when not working from open type feed bin 3
Enter vacuum feed bin 2, the bleeding point 9 on vacuum feed bin top is connected by pipeline 11 with vavuum pump 6,1 is the pump housing in figure.
The use process of embodiment 1 of the present utility model:The slurry loading open type feed bin 3 mixed will be stirred first, closed
The opening and closing valve 5 closed on suction tube 4, makes vacuum feed bin 2 be in closed state, opens vavuum pump 6 by the air in vacuum feed bin 2
Extract out, reach and keep vavuum pump to remain in operation after certain vacuum, opening and closing valve 5 is opened, due to gas pressure, open type material
Slurry in storehouse is inhaled into vacuum feed bin 2 by suction tube 4, because the vacuum feed bin charging aperture 8 of vacuum feed bin 2 is located at thereon
Portion, there is the process for freely dropping and hitting into the slurry in vacuum feed bin 2 during the charging aperture 7 of the pump housing 1 is reached, this
Process is completed under vacuum conditions so that the air bubble expansion in slurry ruptures and discharged, and the gas of release is inhaled by vavuum pump 6
Walk, so that the slurry into the pump housing eliminates bubble, realize the exhaust purpose of slurry.Control opening and closing valve is opened and closed
The time closed, the storage of slurry in vacuum feed bin can be controlled.
In another embodiment of the present utility model, described vacuum feed bin 2 is designed to that top is vertical and cylindrical 2-
