Drawings
FIG. 1 is a schematic view of the structure of the apparatus;
fig. 2 is a schematic view of the movement of particles and water between two electrode rods.
Detailed Description
The technical scheme of the invention is explained in detail in the following by combining the drawings:
as shown in fig. 1, an electrode type rapid dewatering device comprises a bin body 1, wherein the upper half part of the bin body 1 is cylindrical, and the lower half part of the bin body is a 55-degree inverted cone. The inner side of the inverted cone is provided with a bamboo steel weaving-assisting sliding plate embedded in the inner wall of the bin body 1.
This device still includes for the fixed setting in storehouse body 1, vertically stretches into from storehouse body 1 top first sleeve 3 and the second sleeve 9 of the internal portion of storehouse, install anodal electrode stick 4 and negative pole electrode stick 10 with detachable mode respectively in first sleeve 3 and the second sleeve 9. The two electrode rods are directly connected with a power supply.
Specifically, the top of the bin body 1 is provided with a bridge type hoisting frame. The first sleeve 3 and the second sleeve 9 are connected to a hoisting frame. The first sleeve 3 and the second sleeve 9 are also connected with the inner wall of the bin body 1 through connecting rods (not shown in the figure). The first sleeve 3, the second sleeve 9, the positive electrode rod 4 and the negative electrode rod 10 all extend into the inverted cone.
Furthermore, an overflow port 12 (20 cm by 20 cm) is formed in the side wall of the second sleeve 9, and the overflow port 12 is connected with a water outlet pipeline 11 leading to the outer side of the bin body 1.
The top of the bin body 1 is provided with a central tube 2 for feeding, and the central tube 2 is positioned between a first sleeve 3 and a second sleeve 9. An annular cyclone device is arranged in the central cylinder 2, the lower end of the annular cyclone device is an inverted cone-shaped tray, slurry after rotary cutting is uniformly distributed on the tray, and then the dispersion body falls, so that the problem that the slurry is not uniformly distributed due to jet flow is avoided.
The bottom of back taper is equipped with drain hole 5, drain hole 5 is connected with the blowing pipeline. And a concentration meter 6 and a flow meter 7 are also arranged in the discharging pipeline. The discharging pipeline is connected with a conveying device 8.
As shown in figures 1 and 2, when the rotary-cut feed bin works, the material is rotationally cut into the material through the central barrel 2, the material pulp in the bin body 1 is deposited at the bottom of the inverted cone after the sedimentation effect is generated, the process is dehydrated by the dead weight, and the clear water reversely flows upwards through the opening at the bottom of the sleeve. In order to accelerate the particle dehydration process, the electrode bar is electrified in the working process, when the height of the settled and accumulated particles reaches the lower end of the first sleeve 3, the particles near the bin body 1 and the negative electrode bar 10 move to the position near the positive electrode bar 4, water flow flows to the second sleeve 9 and the negative electrode bar 10, and the liquid level in the second sleeve 9 rises. When the liquid level in the second sleeve 9 reaches the overflow port 12, the liquid overflows from the water outlet pipeline 11, and the dehydration process is finished.
As mentioned above, the movement of the particles generates power to drive the slurry accumulated on the inner wall of the bin body 1 to move, so that the slurry on the inner wall of the bin body 1 is driven to be separated, and the problem of hardening of the slurry of fine particles is solved. Because the electrode bar is always in a working state, the settled particles continuously move, and the underflow concentration is high, stable and reliable.
The technology solves the problem of the rapid dehydration process of the particles, accelerates the dehydration capacity of the slurry processed in unit time, simultaneously provides disturbance external force by the electrode bar, and the fine particles move in the bin body 1 without other power drive, thereby forming the slurry with stable concentration. The slurry is finally conveyed outwards through a discharge port 5 at the bottom.
Preferably, the overflow port 12 may be opened at both upper portions of the first sleeve 3 and the second sleeve 9, and the overflow port 12 may be opened and closed. When the positive electrode rod 4 and the negative electrode rod 10 are aligned, the excess water on the first sleeve 3 flows out from the overflow port 12 on the first sleeve 3 (the water outlet pipeline 11 is also connected, and is not shown in the figure). And liquid level detection devices are further respectively arranged in the first sleeve 3 and the second sleeve 9 and are used for detecting the liquid level height in the first sleeve.
