Disclosure of Invention
In view of the not enough of above-mentioned prior art, the utility model aims to provide a concrete aggregate detects and dust collector can absorb the dust automatically high-efficiently after the feeding, solves the dust and scatters excessive problem, realizes environmental protection production.
For solving the above technical problem, the utility model discloses the technical scheme who adopts is:
the utility model relates to a concrete aggregate detects and dust collector has mixer and feed channel, the feed channel top disposes a plurality of feed inlets, and each feed inlet opening part all disposes the negative pressure ring, is equipped with the gyro wheel in the feed channel, still is equipped with the passageway that gathers dust on the mixer, and the passageway that gathers dust passes through negative pressure generating device and connects the dust collector, and the dust collector below is passed through feed back passageway intercommunication mixer, and feed back passageway lower part disposes one-way non return valve.
In the above scheme, the negative pressure ring is connected with the negative pressure generating device through the negative pressure air pipe.
Furthermore, the roller is suspended in the feeding channel through a rotating shaft, the rotating shaft is connected with the feeding channel through a bearing, and one end of the rotating shaft is provided with a linkage device which can be linked with the negative pressure generating device.
Preferably, the linkage is a torque sensor.
Furthermore, a plurality of groove positions are uniformly distributed on the surface of the roller.
Furthermore, a filter layer is arranged in the dust collector, and a back flushing fan is arranged at the upper end of the dust collector.
The beneficial effects of the utility model are that: a plurality of feed inlets are respectively arranged to closely receive materials at the discharge end of each material conveying mechanism, the materials are accurately butted, the dust scattering space is reduced, and each feed inlet is communicated with a negative pressure generating device and is used for solving the dust scattering problem together with a dust collector; the rollers arranged in the feeding channel have a material mixing function and an aggregate feeding detection linkage function, namely, the rollers rotate when the aggregates enter, no aggregate enters when the rollers stop, the system can open the negative pressure generating device to collect dust, and therefore dust scattering and overflowing are avoided, and environment-friendly production is achieved.
Description of the drawings:
fig. 1 is a schematic structural diagram relating to the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
Please refer to fig. 1, the utility model relates to a concrete aggregate detects and dust collector has mixer 1 and feedstock channel 2, feedstock channel 2 top disposes a plurality of feed inlets 3, and each feed inlet corresponds cement, sand aggregate respectively, and the conveying mechanism feed opening of stone aggregate can closely dock the unloading with each aggregate feed opening, reduces scattered excessive space or gap of dust.
The stirring machine 1 is also provided with a dust collecting channel 5, the dust collecting channel 5 is connected with a dust collector 7 through a negative pressure generating device 6, the negative pressure generating device 6 enables the dust collecting channel 5 to generate negative pressure, then floating dust on the upper portion of the stirring machine 1 is sucked and enters the dust collector 7 to be collected, and then clean gas is discharged from the upper portion of the dust collector 7.
A filter layer 52 is arranged in the dust collector 7, the lower part of the dust collector 7 is communicated with the stirrer 1 through a return channel 8, a one-way check valve 81 is arranged at the lower part of the return channel 8, when dust rises along with airflow and passes through the filter layer 52, the dust is blocked by the filter layer 52 and can be scattered into the return channel 8 and then accumulated above the one-way check valve 81, after a certain amount of dust is accumulated, the pressure of the dust forces the one-way check valve 81 to be opened, and the accumulated dust falls back into the stirrer 1.
In order to clean the filter layer 52 on time, the upper end of the dust collector 7 is provided with a back flushing fan 9 which can back flush the filter layer 52 to make the dust attached on the filter layer scatter and fall back to the stirring machine 1 through the material returning channel 8.
And a negative pressure ring 31 is arranged at the opening of each feed port 3, the negative pressure ring 31 is connected with a negative pressure generating device 6 through a negative pressure air pipe, so that part of dust is collected into the dust collector 7 through the dust collecting channel 5, the other part of dust overflows to the feed port 3 and is sucked by the negative pressure ring 31, and the dust also enters the dust collector 7.
Feed channel 2 is the intersection center that prolongs under each feed inlet 3, be equipped with gyro wheel 4 in feed channel 2, 4 surperficial evenly distributed of gyro wheel have a plurality of trench 48, gyro wheel 4 hangs in feed channel 2 through pivot 40, be connected through the bearing between pivot 40 and the feed channel 2, thus, when 3 baits at each feed inlet, each aggregate or cement all can down strike each trench 48 on 4 surfaces of gyro wheel, and then it is rotatory to drive gyro wheel 4, each material also can be thrown away under trench 48's effect and mix in advance in this in-process, be favorable to improving mixer 1's mixing efficiency.
In order to ensure that the negative pressure generating device 6 is not started in the feeding process of the feeding channel 2 and dust is sucked after the feeding is finished, the linkage device 41 is arranged at one end of the rotating shaft 40 and can be linked with the negative pressure generating device 6, the linkage device 41 can adopt a torque sensor, when the roller 4 rotates, aggregate feeding is not finished, when the roller 4 stops rotating, aggregate does not fall down in the feeding channel 2, the PLC system can control the negative pressure generating device 6 to be started, and the dust collecting channel 5 and the negative pressure ring 31 can generate negative pressure to absorb dust.
It should be noted that after the aggregate is fed, the roller 4 continues to rotate for a certain number of turns due to inertia, and the dust cannot spread to the feed inlet 3 immediately in the period of 5-10s, and if the roller 4 stops as soon as possible without external force, a counterweight block can be arranged in the groove 48 to make a certain tangent point of the roller 4 have a larger weight, so that the inertia of the roller 4 is against the weight of the counterweight block without external force, and the number of turns of the inertial rotation of the roller 4 can be greatly reduced.
