The utility model provides powder feeding equipment, relating to equipment for conveying powdery raw materials, particularly to equipment for conveying powdery raw materials to airtight spaces with a certain pressure and temperature. The powder feeding equipment is in a barrel structure. The powder feeding equipment is characterized in that the equipment comprises a push rod, a feeder, a seal door, a gas outlet pipe, a check valve and a seal door control valve, wherein the push rod is arranged in the inner cavity of the feeder, a feeding hole is arranged at one side above the feeder, the gas outlet pipe is arranged at the other side, the seal door is arranged in the cylinder of the inner cavity of the feeder, and the check valve is arranged on a valve seat at one end of the discharge hole of the feeder. The powder feeding equipment is simple in structure and reliable to operate, and easily realizes automatic feeding. Wind and dust return problems caused by the supply of the powder materials to the airtight spaces under the pressure condition are solved.
Description
Technical field
The utility model relates to a kind of load transfer device of powder raw material, especially a kind of in the confined space that certain pressure and temperature are arranged the equipment of conveying powdered raw material.
Background technology
In some present production technology, usually occur need be in the confined space that certain pressure and temperature are arranged the processing step of conveying powdered raw material.In this step, therefore owing in the confined space certain pressure is arranged, the problem that wind returns dirt often appears returning, and being difficult to has influenced production efficiency with powder raw material smooth delivery of power in dynamic environment, more is unfavorable for the clean hygiene with environment of making full use of of raw material.
Summary of the invention
What the utility model solved is exactly to exist at dynamic transport powder raw material in the confined space that certain pressure is arranged to return the problem that wind returns dirt, and a kind of later-model powder feeding device is provided, and can effectively address this problem.
A kind of powder feeding device of the present utility model is a kind of tubular structure, it is characterized in that it comprises charging ram, feeder, hermatic door, gas outlet, check valve and hermatic door control cock; Charging ram is arranged in the feeder inner chamber, and feeder top one side is provided with inlet point, and opposite side is provided with a gas outlet, and hermatic door is arranged in the cylinder body of feeder inner chamber, on the valve seat of feeder discharging opening one end a check valve is set.
Described check valve is fixed on the valve seat of feeder by a spring.
When charging, charging ram and hermatic door all are in top dead point, and inlet point and gas outlet are opening, powder is entered in the feeder inner chamber by the outside, along with entering of powder, the volume of feeder inner chamber dwindles gradually, and the gas in the inner chamber is extruded the back and discharges from gas outlet.When the powder delivery volume reaches requirement, hermatic door is descending under the effect of hermatic door control cock, the complete closed inlet point and the disappointing mouth of pipe, at this moment charging ram is descending under the effect of controlled external force, chamber pressure is increased gradually, to wash check valve open when being increased to the operation pressure that is slightly larger than in the confined space, powder enters in the confined space, when charging ram goes downwards to bottom dead point fully with the powder emptying.When the charging ram backhaul to the complete turn-off transient of check valve, pressure in the pressure of feeder inner chamber and the confined space is identical, along with the charging ram continuation is up, the volume of feeder inner chamber increases gradually, and pressure will constantly reduce, basic consistent when going upward on the inlet point with normal pressure, at this moment hermatic door control cock control hermatic door goes upward to top dead point, and inlet point is opened, and powder enters the feeder inner chamber once more, so repeatedly, be implemented in powder feed under the dynamic environment.
Powder feeding device of the present utility model, simple in structure, operation is reliable, easily is automated feed, has overcome the wind that returns that causes supplying with granular material to the confined space that pressure is arranged and has returned the dirt problem.To economizing in raw materials, realize cleaner production, environmental friendliness has positive effect to guarantee staff's health.
Description of drawings
Fig. 1 is the utility model embodiment 1 charging ram and the structural representation of hermatic door when top dead point.
Fig. 2 is the utility model embodiment 1 charging ram and the structural representation of hermatic door when bottom dead point.
Wherein, charging ram 1, feeder 2, hermatic door 3, gas outlet 4, check valve 5, spring 6, valve seat 7, hermatic door control cock 8, inlet point 9, discharging opening 10, cylinder body 11.
The specific embodiment
Embodiment 1: a kind of powder feeding device, tubular structure.Charging ram 1 is arranged in feeder 2 inner chambers, pump under external force can be in the inner chamber of feeder 2, feeder 2 tops one side is provided with inlet point 9, opposite side is provided with a gas outlet 4, hermatic door 3 is arranged in the cylinder body 11 of feeder 2 inner chambers, it pumps in cylinder body 11 by 8 controls of hermatic door control cock, and hermatic door 3 makes inlet point 9 and gas outlet 4 open when going upward to top dead point, inlet point 9 and gas outlet 4 are closed; Hermatic door 3 strokes are limited by cylinder body 11; On the valve seat 7 of feeder 2 discharging openings 10 1 ends a check valve 5 is set, check valve 5 is fixed on the valve seat 7 of feeder 2 by a spring 6.
When charging, charging ram 1 and hermatic door 3 all are on the position of top dead point, and inlet point 9 is an opening, powder is entered in feeder 2 inner chambers by the outside, along with entering of powder, the volume of feeder 2 inner chambers dwindles gradually, and the gas in the inner chamber is extruded the back and discharges from gas outlet 4.When the powder delivery volume reaches the amount that needs, hermatic door 3 is descending in cylinder body 11 under the effect of hermatic door control cock 8, when coming downwards to the mouth of pipe of complete closed inlet point 9 and gas outlet 4, at this moment charging ram 1 begins descending under the effect of controlled external force, chamber pressure is increased gradually, to wash check valve 5 open when being increased to the operation pressure that is slightly larger than in the confined space, powder is entered in the confined space by discharging opening 10, when charging ram 1 goes downwards to bottom dead point fully with the powder emptying.When charging ram 1 backhaul to check valve 5 complete turn-off transients, pressure in the pressure of feeder 2 inner chambers and the confined space is identical, along with charging ram 1 continuation is up, the volume of feeder 2 inner chambers increases gradually, and pressure will constantly reduce, basic consistent when going upward on the inlet point 9 with normal pressure, at this moment hermatic door control cock 8 control hermatic doors 3 go upward to top dead point, and inlet point 9 is opened, and powder enters feeder 2 inner chambers once more, so repeatedly, be implemented in powder feed under the dynamic environment.
