The specific embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
A kind of cement container case as shown in Figure 1, comprise that top offers the tank body of manhole 1, tank base is provided with support frame, and left tank body and right tank body that tank body is interconnected by inner chamber form, tank body top offers inlet point, and inlet point is connected with the feed pipe 2 that extends to tank body outer lower portion.The quantity of manhole 1 is three.
In the inner chamber of left tank body, be provided with exhaust gear 3, exhaust gear 3 comprises filter, the freeing pipe being connected with filter end, freeing pipe passes left tank body and extends to the outer lower portion of left tank body, in tank body, gas drains into gas in tank body outside tank body by filter and freeing pipe successively, and the material in tank body is but filtered and can not discharges.The bottom of freeing pipe is provided with the blow off valve of controlling gas discharging.
On tank body downside surface, symmetry offers left discharging opening 4, right discharging opening 5, and left discharging opening 4, right discharging opening 5 are connected with left tank body, right tank body respectively, and tank base outside is provided with discharge nozzle 6, and left discharging opening 4, right discharging opening 5 are all connected with discharge nozzle 6 phase pipelines.On pipeline between left discharging opening 4, right discharging opening 5 and discharge nozzle 6, be respectively equipped with for controlling left butterfly valve 7, the right butterfly valve 8 of left discharging opening 4,5 switchings of right discharging opening.
Tank base offers four induction openings 9, two both sides that are positioned at left discharging opening 4 wherein, the both sides that are positioned at right discharging opening 5, two, right side, tank base outside is provided with air inlet pipe 10, four induction openings 9 are all connected with air inlet pipe 10 phase pipelines, be provided with and control its ball valve being interconnected 14 between air inlet pipe 10 and discharge nozzle 6 ends on pipeline.Open ball valve 14, facilitate pressurized air the material in discharge nozzle to be transported to the discharging opening of right-hand member from left end, discharging is complete, noresidue.
Pipeline between induction opening 9 and air inlet pipe 10 is provided with the air inlet ball valve 11 opening and closing for controlling induction opening 9, and air inlet pipe 10 is provided with boiler check valve 12 and compression indicator 13.Between air inlet pipe 10 and freeing pipe, be provided with connection pipe, safety valve 15 is installed on connection pipe.
Tank base inner side is provided with the air-permeable layer 16 being arranged side by side.Air-permeable layer 16 is the surperficial steel plate of offering little sky, and while being conducive to discharging, pressurized air can be uniformly distributed, and prevents feed blocking induction opening 9.
Charging
According to factory's load transfer device in bulk, determine, can feed by single hole, also can porous charging.Method has following two kinds: utilize pressurized air from the inlet valve feeding of feed pipe 2 terminal parts; Utilize manhole 1 feeding.
When filling with substance prevents that lump material from entering in tank body, and charging door is provided with filtering net.In the time of charging, open the blow off valve of exhaust gear 3 ends, be beneficial to air in tank body and drain, facilitate material to enter.The manhole cover outside of manhole 1 is provided with six quick hands of pressing, and opens quick pressure hand and can open manhole cover.
Discharging
Discharging is that material in tank is delivered to Multi-layer material-storing cabinet by pressurized air, and discharge process completes by admission line and discharging pipeline.
Discharging program is as follows:
Tank case is transported to discharging place, and in horizontality; Before discharging, answer examinant's port lid whether in compact state, otherwise will re-cover tightly manhole cover; Check the whether position in " pass " of all valves, otherwise should all shut.
Pull down the stifle of air inlet pipe 10 and discharge nozzle 6 ends, it is Ф 80mm air induction hose that the admission port of air inlet pipe 10 connects internal diameter, and it is Ф 100mm discharging flexible pipe that the discharging opening of discharge nozzle 6 connects internal diameter.
Open four air inlet ball valves 11, when compression indicator pressure rises to 0.2MPa, open ball valve 14, open left butterfly valve 7, right butterfly valve 8, discharging simultaneously.About about 15 minutes, compression indicator pressure drop was to approaching 0.
Close left butterfly valve 7, right butterfly valve 8, close two air inlet ball valves 11 on right side, now two air inlet ball valves 11 in left side are in open mode, close ball valve 14, when tank internal pressure is raised to 0.2MPa again, open ball valve 14, then open left butterfly valve 7, about about 10 minutes, compression indicator pressure can again drop to and approach 0.
Close left butterfly valve 7, close ball valve 14, close two air inlet ball valves 11 in left side, open two air inlet ball valves 11 on right side, when pressure goes back up to while approaching 0.2MPa again, open ball valve 14, open right butterfly valve 8, after about 5 minutes, when compression indicator pressure approaches 0, finish discharging.
Cut off source of the gas, close four air inlet ball valves 11, then close left butterfly valve 7, right butterfly valve 8.Open the blow off valve of freeing pipe end below tank body front end, drain residual air in tank, open manhole cover, check residual rate in tank.Check the complete manhole cover of fastening, close blow off valve.Open the valve of air inlet pipe 10 admission ports, drain residual air in air induction hose, unload air induction hose and discharging flexible pipe, cover admission port and discharging opening stifle.
