Description

Technical Field

[0001] The present invention discloses a multi-directional rotating flocculation enhanced stirring structure and a filter press, which relate to a stirring structure and a filter press with more flocculated sludge, and belong to the technical field of sewage treatment, and particularly to a stirring structure and a filter press with a first rotating motor driving a first rotating rod, an arc-shaped blade and a special-shaped blade of a curved structure to rotate in the same direction, and a plurality of second rotating motors driving corresponding single special-shaped blades to rotate in different directions, so that sewage entering a flocculation mixing cylinder and a flocculant can be more fully contacted, and more flocculated sludge can be stirred and a filter press can be produced. Background Art

[0002] In sewage treatment, filter press is usually used to separate solid and liquid and dehydrate sewage to reduce the water content of sludge. Its working principle is that after the concentrated sludge and a certain concentration of flocculant are fully mixed in static and dynamic mixers, the tiny solid particles in the sludge are aggregated into larger floccules, and free water is separated at the same time. The flocculated sludge is transported to the concentrated gravity dehydration filter belt. Under the action of gravity, the free water is separated to form stagnant sludge, which is then clamped between the upper and lower mesh belts. Under the action of extrusion and shear force from small to large in the wedge-shaped pre-pressure area, low-pressure area and high-pressure area, the sludge is gradually squeezed to achieve the maximum separation of mud and water, and finally the filter cake is discharged. However, the flocculant in the traditional filter press is added into the mixer through the dosing device. When the flocculant is added, it only exists in a certain position of the mixer and is added unevenly. Since the sewage continuously flows into the mixer at a certain flow rate, the sewage and the flocculant cannot fully contact each other before entering the next link, so that part of the sewage cannot be flocculated and flocculent clumps cannot be produced, resulting in low sewage treatment efficiency and poor treatment effect; and when the flocculated sludge moves with the filter belt, a lot of sludge will coagulate and remain on the filter belt, resulting in part of the sludge cannot enter the next link from the filter belt, and is squeezed into a mud cake. There is a lot of residual sludge on the filter belt, which is difficult to clean, affecting the dehydration effect of the filter belt, resulting in low sewage treatment efficiency and poor treatment effect.

[0003] Announcement No. CN107473563A discloses a belt filter press, which mainly includes a frame, a flocculation zone, a concentration and dehydration zone, a gravity dehydration zone and a pressing and dehydration zone, wherein the flocculation zone is provided with a flocculation agitator; the concentration and dehydration zone includes a plurality of horizontally arranged transmission rollers and a concentration filter belt arranged on the transmission rollers; the gravity dehydration zone is located below the concentration and dehydration zone, and the gravity dehydration zone includes a plurality of arc-shaped clamping rollers, an upper filter belt and a lower filter belt fixed on the frame and arranged obliquely; the pressing and dehydration zone includes a plurality of vertically staggered pressing rollers and pressing filter belts, and a demuding roller is also provided at the rear of the pressing roller, and a mud scraper is connected to the demuding roller. The flocculation zone of the above-mentioned filter press is equipped with a flocculation mixer, which can promote the full contact between sewage and flocculant and produce more floccules. However, when the flocculated sludge in the above-mentioned filter press moves with the upper filter belt and the lower filter belt, a lot of sludge will solidify and remain on the upper filter belt and the lower filter belt, resulting in part of the sludge being unable to enter the next link from the upper filter belt and the lower filter belt and being squeezed into mud cakes. There is a lot of sludge remaining on the upper filter belt and the lower filter belt, which is difficult to clean, affecting the subsequent gravity dehydration effect, thereby resulting in low sewage treatment efficiency and poor treatment effect.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A filter press", in which the first rotating motor and the second rotating motor are started, the first rotating motor drives the first rotating rod and the stirring blade to rotate in the same direction, and the second rotating motor drives the second rotating rod and the corresponding single stirring blade to rotate in different directions, so that the sewage and flocculant entering the flocculation mixing cylinder can be more fully contacted, and more sludge can be flocculated. However, the first rotating rod in the above filter press is a vertical structure, and vortices will be generated when the sewage and flocculant are stirred, resulting in the agglomeration of the sewage and flocculant, affecting the diffusion of the flocculant in the sewage, and the first rotating rod is not provided with stirring blades, and the stirring effect of the sewage and flocculants in the middle of the flocculation mixing cylinder is poor, resulting in part of the flocculant not being able to fully contact the sewage, and less sludge after flocculation; the stirring blade with a smooth surface has a small contact area with the sewage and flocculant, and the turbulence and shearing effect generated are poor, and the stirring effect is poor, resulting in part of the flocculant not being able to fully contact the sewage, and less sludge after flocculation, thereby resulting in low sewage treatment efficiency and poor treatment effect. Summary of the invention

When the dehydrated sludge enters the mud collecting box (16), it is easy to be squeezed into blocks under the action of gravity. The mud collecting box (16) with one side being an openable and closable structure is more convenient for directly transferring the sludge in the mud collecting box (16) and can prevent the sludge from accumulating at the bottom of the mud collecting box (16) to form stubborn sludge.

[0020] The flocculation component can be used to make the sewage and the flocculant fully contact, so that more sludge is produced after flocculation. The sludge is pushed and dehydrated for the first time through the transmission component, and the sludge is dehydrated again through the filter press component, so as to improve the efficiency and effect of sewage treatment.
