Abstract
Sealing charging valve, relates to hopper field.Comprise hopper, the lower end of described hopper arranges discharging opening, and the upper end of described hopper is provided with charging bulkhgead gate, and charging bulkhgead gate is provided with bell hermetically-sealed construction, and the discharging opening of hopper is provided with the sealed gate automatically controlled.Inlet point of the present utility model is provided with charging bulkhgead gate, and discharging opening is provided with bell, and during charging, charging bulkhgead gate is opened, and bell is closed, and material enters in hopper by raw material cabin; When needs discharge, charging bulkhgead gate cuts out, and bell is opened, and and so forth, the combined and alternatively of charging bulkhgead gate and bell runs.The bulkhgead gate of charging simultaneously, bell are all provided with hermetically-sealed construction, can prevent dust from leaking, effectively stop the reverse flow of air-flow, thus ensure that the normal discharge of intrasystem stable gas pressure and material.
Description
Technical field
The utility model relates to hopper field, is specially a kind of sealing charging valve.
Background technology
Hopper is widely used in mass transport field, and of a great variety, various structures, but still has the place of more To be improved: 1, the sealing effectiveness of existing hopper is poor, easily leaks in the course of conveying of granular material.2, in course of conveying, doses can not accurately control, and cannot meet complicated technology and the needs produced that become more meticulous.3, complex operation, maintenance, maintenance inconvenience.
Utility model content
It is better that the purpose of this utility model is to provide a kind of sealing effectiveness, the sealing charging valve that mass flow can accurately control.
The technical scheme realizing above-mentioned purpose is: sealing charging valve, comprise hopper, the lower end of described hopper arranges discharging opening, and the upper end of described hopper is provided with charging bulkhgead gate, charging bulkhgead gate is provided with hermetically-sealed construction, and the discharging opening of hopper is provided with the sealed gate automatically controlled.
Above-mentioned charging bulkhgead gate comprises lock frame, lock frame is provided with inlet point, and the lower port of lock frame inlet point is plugged with flashboard, and the both sides of flashboard are connected to horizontally disposed first oil cylinder, tail end and the lock frame of both sides first oil cylinder are fixed, and the rod end of both sides first oil cylinder is connected with flashboard; The flashboard upper and lower in lock frame charging choma week is respectively arranged with seal groove, packing seal is provided with in seal groove, the lower end of the packing seal below the upper end of the packing seal above flashboard and flashboard is connected to holddown spring, compressed by holddown spring, be fitted on flashboard by the packing seal of flashboard upper and lower, the other end of holddown spring is all connected on the inner side end of corresponding seal groove.The sealed gate that the discharging opening of above-mentioned hopper is arranged comprises bell, and the lower loop week of bell is sealed and matched with the discharging opening of hopper, and the upper end of described hopper is connected with vertically arranged second oil cylinder, and the rod end of the second oil cylinder is connected with the upper end of bell.
Also level-sensing device is installed in above-mentioned hopper.
The beneficial effects of the utility model:
1, inlet point of the present utility model is provided with charging bulkhgead gate, and discharging opening is provided with bell, and during charging, charging bulkhgead gate is opened, and bell is closed, and material enters in hopper by raw material cabin; When needs discharge, charging bulkhgead gate cuts out, and bell is opened, and and so forth, the combined and alternatively of charging bulkhgead gate and bell runs.The bulkhgead gate of charging simultaneously, bell are all provided with hermetically-sealed construction, can prevent dust from leaking, effectively stop the reverse flow of air-flow, thus ensure that the normal discharge of intrasystem stable gas pressure and material.
2, hopper of the present utility model is built with level-sensing device, and when at when filling with substance, charging bulkhgead gate is opened, and bell is closed, and the bed of material slowly rises, and just can be learnt the upper limit of doses by continuous material level meter; When discharging, the bed of material slowly declines, and just can be learnt the upper limit of doses by continuous material level meter, so just can accurately grasp doses number, then by coordinating of interlocking with charging bulkhgead gate, bell opening and closing, thus meet system and to become more meticulous the needs produced.
3, the bell that charging bulkhgead gate and discharging opening are arranged all is operated by hydraulic actuating cylinder, realizes remote monitor and control by electrical controller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is part sectional view of the present utility model.
