Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
Specific embodiment one, is described with the situation that equipment is a powder hopper body:
As shown in Figure 1 to Figure 3, equipment is followed successively by from the bottom to top: concrete mixing plant stirring host 1, aggregate bin 2, installing rack 3, powder hopper body 4, and in order to the ventilative pipeline 5 of connected set hopper 2 and powder hopper body 4.Aggregate bin 2 bottom is provided with discharge duct 21, and discharge duct 21 stretches in stirring host 1 downwards; Powder hopper body 4 is arranged on installing rack 3, is provided with butterfly valve 41 bottom it, for controlling the folding of the powder passage leading to aggregate bin 2; Powder hopper body 4 is provided with powder hopper body ventilation mouth 45, and it is interconnected by ventilative pipeline 5 with the aggregate bin ventilation mouth 22 be arranged on aggregate bin 2.In addition, powder hopper body 4 top is also provided with feed pipe 46, is provided with inductor 43 in powder hopper body 4, and vibrator 42 is arranged on the rear lower outer wall of the transition feed bin 44 of powder hopper body 4; Ventilative pipeline 5 is made up of permeability cell 51 and pipeline connecting parts 521.
In above-mentioned connection, feed pipe 46 uses welding manner or flange arrangement and powder hopper body 4 to be rigidly connected; Powder hopper body ventilation mouth 45 is arranged at powder hopper body 4 top, by flange arrangement and pipeline connecting parts 521, is inverted V-shaped pipe in present embodiment, one end be rigidly connected; Permeability cell 51 uses spring sweep-up pipe, and its one end with pipeline connecting parts 521 and aggregate bin ventilation mouth 22 are connected respectively by dead ring; Aggregate bin 2 uses carbine to hang under installing rack 3; Be connected by flexible pipe and dead ring between aggregate bin 2 with powder hopper body 4; Discharge duct 21 uses flange arrangement fastening with aggregate bin 2 lower body part; Discharge duct 21 stretches in stirring host.
Powder enters the transition feed bin 44 of powder hopper body 4 from the feed pipe 46 at powder hopper body 4 top, the powder amount that sensor 43 is metered into, and after powder charging has been measured, butterfly valve 41 is opened, and powder enters stirring host 1 through aggregate bin 2 successively.
In above process, portion gas is brought into when powder enters powder hopper body 4, due to the conducting effect between powder hopper body 4 and aggregate bin 2, this portion gas shifts along the gas-permeable channels be made up of powder hopper body ventilation mouth 45, pipeline connecting parts 521, permeability cell 51 and aggregate bin ventilation mouth 22 to aggregate bin 2 and stirring host 1, do not act on powder and sensor 43, do not cause phenomenon relatively heavy per unit volume; When powder metering completes, butterfly valve 416 is opened, powder enters stirring host through aggregate bin 2, gas in aggregate bin 2 and stirring host 1 is shifted by the gas-permeable channels that is made up of aggregate bin ventilation mouth 22, permeability cell 51, pipeline connecting parts 521 and the powder hopper body ventilation mouth 45 transition feed bin 44 to powder hopper body 2, do not act on butterfly valve 6 and sensor 4, do not cause holder scale phenomenon; The gas pressure energy imbalance of stirring host operationally its inside cavity also can be undertaken regulating and balancing by above-mentioned gas-permeable channels.
Described pipeline connecting parts 521 is inverted V-shaped pipe, can effectively tackle the powder kicked up in fill process while by gas, makes powder cannot directly enter aggregate bin 2 and stirring host 1 by ventilative pipeline.
Specific embodiment two is that the situation that two powder hopper bodies are is described with equipment:
As shown in Figures 4 to 6, mounting arrangement and the precedent of equipment are similar, and its different piece has: the number of powder hopper body 4 is two; Ventilative pipeline 5 is made up of permeability cell 51 and pipeline connecting parts 522, and wherein pipeline connecting parts 522 is the special-shaped t-bend pipe of pinnacle structure.
Above-mentioned pipeline connecting parts 522, i.e. the special-shaped t-bend pipe of pinnacle structure, two port cross-sectional connected with powder hopper body 4 amass equal, and the port cross-sectional be connected with permeability cell 51 amasss and is greater than two port cross-sectional be connected with powder hopper body 4 and amasss sum.The port that wherein sectional area is maximum and permeability cell 51, namely spring sweep-up pipe, is connected by dead ring, and two other port uses the powder hopper body ventilation mouth 45 on flange arrangement and two powder hopper bodies 4 to form respectively and is rigidly connected.
Pipeline connecting parts 521 used in above-mentioned two specific embodiments, i.e. inverted V-shaped pipe, with pipeline connecting parts 522, the i.e. special-shaped t-bend pipe of pinnacle structure, can effectively tackle the powder kicked up in fill process while by gas, make powder cannot directly enter aggregate bin 2 and stirring host 1 by ventilative pipeline 5.Especially, the use of the special-shaped t-bend pipe of pinnacle structure, simplifies the structure of powder scale, has saved the consumption of permeability cell, avoids the confusion of powder scale equipment pipeline.
Powder scale on concrete mixing plant described in the utility model, by use ventilative pipeline 5 connect in powder hopper body 4 with aggregate bin 2, make powder hopper body 4 air pressure inside and aggregate bin 2 and stirring host 1 air pressure inside equal at any time, avoid relatively heavy per unit volume, the holder scale phenomenon that cause because sensor 43 top and the bottom air pressure is uneven, ensure that the accuracy that powder scale measures.Meanwhile, be applied to pipeline connecting parts 521 and the pipeline connecting parts 522 of different situations, can effectively tackle the powder kicked up in fill process, avoid powder and loss and directly enter aggregate bin 2 or stirring host 1 without metering.The use of the special-shaped t-bend pipe of pinnacle structure, simplifies the structure of powder scale in addition, has saved the consumption of permeability cell, avoids the confusion of powder scale equipment pipeline.
Above are only two detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
