One charging line in N-shaped is connected, and one end of this N-shaped pipeline is near ground, for being connected with powder tank car, the pump into feed pipe
Enter powder, the other end of feed pipe then upwardly extends and stretches into powder upper end after circular arc curve transition at powder upper end, finally
Stretch to a certain suitable space position along powder tank axis direction straight down, so that aborning, after powder tank car arrives at a station,
Powder is first from bottom to top pumped into the top of powder tank from ground, then along feed pipe be delivered to downwards static, deposition in powder tank,
Storage；When using, using being arranged on the flour extraction pipe road at the tank bottoms end of powder by powder carry to the agitator tank mixing and stirring in tower.Due to
Powder is dust material, so using high-pressure pump by its pump to powder tank, then just creating higher pressure in powder tank.In order to
For the sake of safety, the powder tank of part mixing plant directly adopts open powder tank, and that is, the top of powder tank is provided with opening, and atmosphere,
It is easy to discharge in time pressure inside the tank；Although this powder tank junction structure is simple, with low cost, due to its open top, in pump
When entering powder, often dust flashes, and just as individual chimney, environmental pollution greatly, and leads to a large amount of powders to waste to whole powder tank.
Though current some small part powder tanks are provided with the pressure that the pressure relief devices such as relief valve come in balance pipe body, due to pressure relief device
It mostly is pure gas relief valve, valve core structure is also relative complex, is not suitable for the excretion of powder this high concentrate dust air-flow, easily
Result in blockage, bury potential safety hazard, and existing relief valve is all to direct out boundary's pressure release aerofluxuss, therefore, the dust of exclusion is still
So diffuse in atmosphere, pollution and waste all do not have elimination.
Powder reclaims and can arrange pipeline on the top of powder tank, dust is introduced and carries out storage utilization elsewhere, but,
When dust is due to circulating in pipeline, the long-time easy afterwards very thick one layer of powder of accumulation, in ttom of pipe, finally still can cause ttom of pipe
Blocking and the waste of powder.And existing concrete mixing plant is typically equipped with multiple powder tanks, the aerofluxuss in order to realize powder tank are let out
Pressure, is all individually provided with pressure relief valve in each powder upper end, or is provided with corresponding pipeline, in order to by the aerofluxuss of all powder tank tops
Mouth connection, is all horizontally disposed yet with each pipeline, when the dust in pipeline flows freely, can produce in a large number in pipeline
Powder precipitates, and blocks pipeline；And the dust in manual removal pipeline, complex operation, powder is recycled not in time, easily
It is wasted.

On Motor Foundation, setting idler gear f5 can be further up to suitable slewing range.
Further, as shown in fig. 6, described main shaft c1 and shell e joint are fixed with bearing block c3, in bearing block c3
It is provided with deep groove ball bearing c2, main shaft c1 passes through the shaft shoulder c101 on this deep groove ball bearing c2 and main shaft c1 to be close to the end of this bearing
Face, is for the ease of bearing produced by main shaft c1 axially and radially power simultaneously using deep groove ball bearing c2.Herein, with regard to main shaft
The concrete mounting means of c1, is all prior art it is achieved that on the basis of said structure, also can set in the other end of main shaft c1
Put bearing and bearing block, bearing block can be fixed in recovery channel 108, and select the bearing with dust cap, so that main shaft c1 is more
For neatly rotating.
Further, the angle between the valve port axis of described valve j and its reclaimed materials pipeline section axis of being located is 30 degree,
And the incline direction of valve j is consistent with the incline direction of reclaimed materials pipeline section that it is located, first reclaim expects pipe 3 and the second reclaimed materials
The valve j of pipe 5 has a down dip (rear side inclination) to rear side, the 3rd recovery expects pipe 4 about two ends valve j respectively to by under, sit down
Roll tiltedly, thus ensure compressed air stream after valve j entrance can to become suitable angle flush pipe bottom with flow velocity direction in pipeline,
Reach the effect of optimal flush pipe bottom powder.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for limiting this practicality
Type.Any person skilled in the art all can be carried out to above-described embodiment without prejudice under spirit and the scope of the present utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in this utility model
