After the on-site pipe network system is determined, the on-site pipe network system is automatically cleaned and started to operate.
The airflow with the fibers enters the volute 2 and the shell 1 through the air inlet 4, the rotational flow and the cyclone are formed in the volute 2 and the dust cage 7, the air is discharged through the meshes of the dust cage 7, and the fibers are driven by the rotational flow and the cyclone to not condense on the inner surface of the dust cage 7 and gradually rotate downwards and enter the cotton collecting hopper 3 through the cotton outlet for sedimentation; thereby achieving non-destructive collection of the fibers. A guide cylinder 6 is arranged in the volute 2 and extends to the middle part of the shell 1; a dust cage 7 is arranged in the shell 1; the lower extreme of dirt cage 7 is connected with the cotton mouth of a cone section of thick bamboo 10, and cotton mouth is the toper mouth, extends to in the cotton collection fill 3.
The air inlet 4 is vertically arranged on the volute 2, and the air inlet 4 and the volute 2 form a certain vortex shape together, so that after fiber-containing air flow enters the device from the air inlet, the fiber-containing air flow can rotate along the guide cylinder 6 arranged in the middle, and a rotating air flow is formed. The spinning gas flow contains fine dust, and is influenced by gravity to gradually flow downwards, namely, flows into the dust cage 7 from the inside of the volute 2 in a rotating way. The surface of the dust cage 7 is provided with filter meshes 8 for releasing air from the dust cage 7 and further out through the air outlet 5.
When air leaves from the inner side of the dust cage 7 through the filter mesh holes 8 on the surface of the dust cage 7 and enters the space between the dust cage 7 and the shell 1, the rotating airflow speed in the dust cage 7 is continuously reduced, the scouring effect of the airflow on the inner wall of the dust cage is gradually reduced, and the fibers are attached to the surface of the dust cage 7 under the action of adsorption force; if the rotating force provided by the rotating air flow to the fibers is insufficient, the fibers are remained on the surface of the dust cage 7, even hang up and block the filter meshes, and the smooth sedimentation of the fibers into the cotton collecting hopper cannot be ensured. With the gradual downward rotation and flow of the air flow, the air continuously flows away through the filter mesh holes 8 on the surface of the dust cage 7, which tends to reduce the wind speed and further influence the sedimentation of the fibers; in particular in the vertical direction of the dust cage 7, the closer to the bottom of the dust cage 7, the lower the wind speed of the rotating air flow. In order to keep the wind speed of the air flow in the dust cage 7 high enough, the fiber can be driven to be smoothly transferred into the cotton collecting hopper 3. The main body of the dust cage 7 is a net drum with filter meshes 8; a cone cylinder 10 is arranged below the dust cage 7 and is connected with a cone opening of the cotton outlet, and no filter mesh is arranged on the cone cylinder 10; a mounting hole 11 for fixing the arc-shaped baffle plate 12 is arranged on the dust cage 7, and the mounting hole 11 is used for fixedly mounting the arc-shaped baffle plate 12; the arc baffle 12 is installed on the outer surface of the dust cage 7, and the air speed of the rotating air flow at the lower side of the dust cage is ensured by selecting a proper arc baffle 12 to adjust the quantity and the area ratio of the filter meshes 8 which can supply air at the lower half part of the dust cage 7. The local ventilation resistance of the filter mesh holes at the upper part and the lower part of the dust cage is uniform and stable, so that the working fiber of the lower side rotating air flow at a lower wind speed is ensured not to paste the mesh; preferably, the wind speed of the air flow through the mesh is generally controlled at 5m/s. The arc-shaped baffle 12 has an arc-shaped area which is attached to the outer surface of the dust cage 7, so that the filter mesh 8 on the surface of the dust cage 7 is blocked as much as possible, and unnecessary leakage between the dust cage 7 and the arc-shaped baffle 12 is prevented, and fibers are adhered to the inner side of the dust cage 7.
Preferably, the upper width of the arc-shaped baffle 12 is small, and the lower width is large, in this embodiment, the arc-shaped baffle 12 is conical, the small end is arranged at the position above the dust cage 7, and the large end is arranged at the position below the dust cage 7; the specific shape and number of arcuate baffles 12 may be designed and configured accordingly based on the wind speed of the different streams entering the apparatus, the rotational speed of the fibers, and the characteristics of the different fibers.
Preferably, if the size and the number of the arc-shaped baffles 12 do not need to be adjusted, the arrangement of the filter meshes 8 on the dust cage 7 can be directly adjusted, the number of the filter meshes 8 above the dust cage 7 is more, and the number of the filter meshes 8 below the dust cage 7 is smaller, so that the step change of the number of the effective meshes in the vertical direction of the dust cage 7 is realized, and the same effect as that of the arc-shaped baffles 12 is realized.
Also, it is preferable that the filter mesh 8 is not provided at a side close to the air outlet 5 to prevent excessive passing wind speed at the air outlet 5 side from affecting the falling of the fiber for collection.
The lower part of the dust cage 7 is provided with a sealed cone cylinder 10, when the dust-containing air flow is decelerated by the guide cylinder 6, the dust-containing air flow enters the cone cylinder 10, is converged under the driving of the air flow, and falls down and enters the cotton collecting hopper 3 through the cotton outlet.
A certain air flow can exist at the outlets of the cotton collecting hopper 3 and the cotton outlet and enters the cotton collecting hopper 3; if the air speed of the part of air flow is too high, the fibers in the cotton collecting hopper 3 are blown up, so that the spraying phenomenon is caused, the environment is polluted, and the collection of the fibers is not facilitated; in order to reduce the wind speed of the partial air flow, an inner circulation air outlet 9 is arranged on a circular ring connected with the shell 1 at the top of the cotton collecting hopper 3.
Preferably, the internal circulation air outlet 9 is also provided with an internal circulation air quantity adjusting device, and the internal circulation air speed in the cotton collecting hopper 3 is adjusted by adjusting the area of the internal circulation air outlet which can actually supply air, so that the air pressure static pressure value of the inner wall of the cotton collecting hopper 3 on the water surface of the cotton outlet is controlled to be +/-20 Pa; further preferably, the static pressure value is controlled to be +/-5 Pa, so that the fibers are settled and piled up, and collection is facilitated.
Preferably, at the position close to the air outlet 5, the inner circulation air outlet 9 is not arranged, so that local negative pressure generated by the inner circulation air outlet 9 is prevented from being too concentrated, and further fiber settlement in the cotton collecting hopper 3 at the inner side of the inner circulation air outlet 9 near the air outlet 5 is influenced, so that the fiber is sucked out from the inner circulation air outlet 9 near the air outlet 5 and is discharged out of the equipment through the air outlet 5.
The advantages are that:
(1) The dust cage 7 rotates according to the airflow direction, the holes of the filter mesh 8 are arranged in a stepped mode, the ventilation resistance is small, and the hidden danger of pasting the mesh is avoided;
(2) The cotton outlet of the cone cylinder 10 is optimally designed, so that the discharge air quantity is minimized, and the material-air ratio reaches 0.5;
