Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a magnetic seed recovery device. Background Art

[0002] Magnetic flocculation water treatment technology is currently a commonly used sewage treatment technology. It uses magnetic seeds as a medium to cause the dirt in the sewage to aggregate and form flocs, thereby separating the dirt in the sewage. Since magnetic seeds are expensive and can be recycled, in order to reduce costs, treatment plants usually use magnetic seed recovery equipment to recycle and reuse magnetic seeds in sludge.

[0003] The magnetic seed recovery equipment first disperses the magnetic seed sludge flocs at high speed through high-speed shear paddles to initially separate the magnetic seed from non-magnetic substances, and then separates the magnetic seed from the sludge through a magnetic drum and adds it to the stirring chamber for dilution and stirring to form a magnetic seed mixture for addition to the sewage to be treated. Since the magnetic drum will inevitably be accompanied by sludge when adsorbing the magnetic seed, in order to improve the recovery rate of the magnetic seed, the traditional method is to add a water spray mechanism to spray water on the magnetic drum, thereby flushing away the sludge attached to the magnetic seed. However, in actual use, it was found that the flushing effect of the sludge on the magnetic seed by spraying water only by the water spray mechanism is limited, and there is still a lot of sludge residual, and part of the flushed magnetic seed will flow into the stirring chamber, and the improvement of the magnetic seed recovery rate is limited.

[0004] In addition, the traditional magnetic seed recovery equipment has problems such as poor dispersion of magnetic seed sludge flocs, dead corners in the stirring chamber, and the inability to judge the liquid level in the stirring chamber. Therefore, it is necessary to make new innovations. Utility Model Content

A flow channel opening 141 is provided near the upper end on the first partition plate 14 between the high shear chamber 11 and the magnetic drum chamber 12, which is the outlet of the high shear chamber 11 and the inlet of the magnetic drum chamber 12. The magnetic seed sludge mixture in the high shear chamber 11 flows into the magnetic drum chamber 12 through the flow channel opening 141. A shearing paddle 2 is provided in the high shear chamber 11, which is driven by a high-speed motor and rotates at a high speed in the high shear chamber 11, thereby shearing and dispersing the sludge magnetic seed flocs flowing into the high shear chamber 11 at a high speed. Preferably, a spoiler ridge 111 is provided on the bottom wall of the high shear chamber 11, such as Figure 3 and Figure 4 As shown in the figure, a cross-shaped flow-disturbing ridge 111 is provided on the bottom wall of the high-shear chamber 11, which can disturb the fluid in the high-shear chamber 11 when the shearing paddle 2 rotates to generate turbulence, thereby enhancing the dispersion effect of the shearing paddle 2 on the magnetic seed sludge flocs in the high-shear chamber 11 and improving the magnetic seed recovery rate. Since the high shearing effect on the magnetic seed flocs of the sludge is a conventional technology, the specific structure and driving method of the shearing paddle 2 are not the focus of the protection requested by this application, so they will not be described in detail here.

[0031] A rotatable magnetic drum 3 is arranged in the magnetic drum chamber 12. The axial direction of the magnetic drum 3 is consistent with the width direction of the main body 1. Both ends of the rotating shaft of the magnetic drum 3 are rotatably connected to the main body 1. A scraper 4 is arranged on the water inlet side of the magnetic drum 3. Specifically, an arc-shaped partition plate 16 matching the magnetic drum 3 is arranged below the magnetic drum 3 in the magnetic drum chamber 12, and the arc-shaped partition plate 16 is welded and fixed to the two width side walls of the main body 1 respectively. One end of the arc-shaped partition plate 16 in the length direction extends to the flow channel opening 141, so that the magnetic seed sludge mixture in the high shear chamber 11 can flow between the magnetic drum 3 and the arc-shaped partition plate 16. The magnetic drum 3 has magnetic force and can be driven to rotate by the magnetic drum driving motor, such as Figure 2As shown in , the left side of the magnetic drum 3 is the water outlet side, and the right side of the magnetic drum 3 is the water inlet side. The magnetic blocks on the magnetic drum 3 are preferably in the shape of arc tiles, which can increase the magnetic force of the magnetic drum 3.

During assembly, the sipping plate 72 is placed between the clamping plate 712 and the support rod 711, and then the clamping plate 712 is fixed to the support rod 711 to clamp the sipping plate 72 to the support rod 711. The clamping plate 712 and the support rod 711 are preferably locked and fixed by a detachable fastener such as a bolt. In order to improve the clamping effect of the water-squeezing plate 72, the clamping surface of the clamping plate 712 or the support rod 711 can be provided with some protruding structures or groove structures. The above-mentioned design structure is simple, and it is also very convenient to disassemble and replace the water-squeezing plate 72. By arranging the water-squeezing device 7 after the flushing device 6, the sewage generated by the flushing device 6 when flushing the magnetic seed can be scraped off between the magnetic drum 3 and the arc partition 16. On the one hand, it can reduce the sewage from flowing into the stirring chamber 13, and on the other hand, it can also play the role of scraping and brushing the magnetic seed, further removing the sludge on the magnetic seed, and effectively improving the recovery rate of the magnetic seed.

[0035] The water replenishing device 8 is preferably a water spray pipe, which is provided with a water spray port aimed at the rear upper surface of the magnetic drum 3.

A water inlet 162 is provided near the other end of the arc partition 16, and the water flowing through the magnetic drum 3 flows into the water tank structure through the water inlet 162, and then is discharged through the drainage port 191 on the water tank structure.

[0037] The stirring chamber 13 is provided with a stirring paddle 5, which can be driven by a stirring drive motor to stir the magnetic seeds dropped into the stirring chamber 13, so that the magnetic seeds and the water in the stirring chamber 13 form a magnetic seed mixture, which is finally pumped by a pump and added to a designated device for reuse. Since the stirring effect on the magnetic seeds is a conventional technology and is not the focus of protection requested by this application, it will not be described in detail here. Since the stirring chamber 13 generally adopts a square cavity design, there will be dead corners at the corners of the stirring chamber 13, which can easily lead to accumulation of magnetic seeds. Therefore, it is preferred to vertically set spoilers 131 at the corners of the stirring chamber 13, such as Figures 2 to 5 As shown, on the one hand, it can play a disturbing role to generate turbulence in the stirring chamber 13 and improve the mixing effect of the magnetic seeds; on the other hand, it can also eliminate dead corners in the stirring chamber 13 and avoid the accumulation of magnetic seeds in the stirring chamber 13.
