Abstract
The utility model relates to the technical field of drying equipment in the chemical industry, foods, medical treatment and the like, in particular to a special discharging device with flap type valves for the vacuum drying equipment. The special discharging device with the flap type valves for vacuum drying equipment comprises a vacuum collection storage tank, a material transfer tank, a normal pressure collection tank, a feeding device and a grinder, wherein one flap type valve is arranged between the vacuum collection storage tank and the material transfer tank; the other flap type valve is arranged between the material transfer tank and the normal pressure collection tank; actuators are arranged on the flap type valves; a transmission shaft is connected to the actuators; a connecting rod is arranged on the transmission shaft; a valve plate is arranged on the connecting rod. According to the special discharging device with the flap type valves for the vacuum drying equipment, the valves are finally pressed and sealed by utilizing the pressure difference between vacuum and atmospheric pressure; because materials do not generate relative rub with sealing elements in the conveying process, compared with a butterfly valve, seal of the valves is difficult to wear, and the service life is longer; the valves are provided with special quick-open type maintenance units, so that the valves are easier to maintain compared with the butterfly valve.
Description
Technical field
The utility model relates to the drying equipment technical fields such as chemical industry, food, medical treatment, especially a kind of vacuum dryer discharging device special with turnover plate type valve.
Background technology
Current vacuum dryer generally uses butterfly valve (as Fig. 5) to be integrated in the pipage control that completes dried powder material in its material-receiving system, the encapsulant that butterfly valve adopts is ethylene propylene diene rubber or silicon rubber, in the process that valve plate opens and closes granular solids material can with the mutual extrusion friction of valve seals, when some bulk materials is stuck in valve plate and contacts position with sealing ring, this friction can become even more serious, the wearability of its sealing parts does not meet the requirement of actual production, so being suitable for, this body structure of butterfly valve do not carry and controls solid particle material, the result damage that the sealing ring of butterfly valve can be exceedingly fast often, cause leakage, and butterfly valve is changed sealing ring as need often to be needed its whole disassembling from system, maintenance is difficult for.
Utility model content
Poor in order to overcome the sealing of existing valve, and the deficiency of maintenance difficult, the utility model provides a kind of vacuum dryer discharging device special with turnover plate type valve.
The utility model solves the technical scheme that its technical problem adopts: a kind of vacuum dryer discharging device special with turnover plate type valve, comprise pay-off, pulverizer and valve body, between described vacuum rewinding storage tank and material unloading tank, be provided with turnover plate type valve one, between material unloading tank and normal pressure rewinding tank, be provided with turnover plate type valve two, described turnover plate type valve one and turnover plate type valve two are provided with actuator, connection for transmission axle on described actuator, described power transmission shaft is provided with connecting rod, described connecting rod is provided with valve plate, between the valve body of described turnover plate type valve one and turnover plate type valve two and valve plate, be provided with silicone rubber O-ring, " C " type that is shaped as of described silicone rubber O-ring.
The beneficial effects of the utility model are, this vacuum dryer discharging device special with turnover plate type valve, this valve seal utilizes vacuum and atmospheric pressure reduction to realize final press seal, because material does not produce relative friction with seal in course of conveying, than butterfly valve, the sealing of this valve is not easy wearing and tearing, longer service life, valve design has special fast-open type maintenance unit, than butterfly valve easy care more.
