Description

Technical Field

[0001] The present invention discloses a filter press sludge vibration crushing structure and a filter press, which relate to a structure capable of vibrating and crushing large sludge, and belong to the technical field of sewage treatment, and particularly to a crushing structure and a filter press, which can vibrate a vibrating sludge discharge plate through a vibration motor so that large sludge falling on the vibrating sludge discharge plate is crushed and then enters a filter press box through a sludge discharge port, and can vibrate and crush large sludge, thereby improving the filtration effect of the filter press. 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 is fully mixed with a certain concentration of flocculant in a static and dynamic mixer, 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 pressure 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 form a filter cake for discharge. 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 residual sludge 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 flocculated sludge is first dehydrated through a transmission component. The sludge after the first dehydration enters the first mud conveying channel from the other end of the transmission pipe under the action of gravity, enters the second mud conveying channel from the first mud conveying channel, and enters between the upper and lower filter belts of the filter press box from the second mud conveying channel, and is squeezed by the upper and lower pressure rollers. However, the sludge after filtering by the transmission component still has lumps, and the lumps that are too large cannot be effectively processed, resulting in the blockage of the upper and lower filter belts, affecting the re-dehydration of the sludge by the upper and lower filter belts, and affecting the normal operation of the filter press.

[0015] The difference between this embodiment and embodiment 1 is that: a spring placement groove (44) is provided on the side of the vibrating mud discharge plate (40); the diameter of the vibrating mud discharge plate (40) is equal to the inner diameter of the second mud delivery channel (12); the edge of the vibrating mud discharge plate (40) is connected to the inner side of the second mud delivery channel (12); there are a plurality of spring placement grooves (44); the plurality of spring placement grooves (44) are arranged equidistantly along the circumferential direction of the side of the vibrating mud discharge plate (40); one end of the support spring (39) is placed on the bottom surface of the spring placement groove (44); and the other end of the support spring (39) is placed on the inner side of the second mud delivery channel (12); when in use, there is no gap between the vibrating mud discharge plate (40) and the inner side of the second mud delivery channel (12), thereby preventing some large pieces of sludge from entering the filter press box (13) through the gap between the vibrating mud discharge plate (40) and the inner side of the second delivery channel, causing blockage of the upper and lower filter belts (34) and affecting the filtration effect of the filter press; The design of movably connecting one end of the support spring (39) to the side of the vibrating mud discharge plate (40) makes it easier to disassemble the vibrating mud discharge plate (40) for cleaning, thereby preventing the mud discharge port (41) from being blocked by mud remaining on the vibrating mud discharge plate (40) after the vibrating mud discharge plate (40) has been used for a long time; The vibrating mud discharge plate (40) is an arc-shaped structure, and the height of the vibrating mud discharge plate (40) is designed to gradually increase from the center to the edge, which can increase the contact area between the vibrating mud discharge plate (40) and the mud, and is more conducive to the mud being concentrated in the center of the vibrating mud discharge plate (40), thereby preventing the mud from splashing onto the inner side of the second mud conveying channel (12) during the vibration process; The vibrating mud discharge plate is designed as a structure with multiple arc bends from the center to the edge, which can increase the contact area between the vibrating mud discharge plate (40) and the mud, and is more conducive to the vibrating mud discharge plate (40) vibrating and crushing more mud, thereby improving the vibration crushing efficiency of the mud; A sealing ring is provided between the vibrating mud discharge plate (40) and the inner side surface of the second mud delivery channel (12) except for the support spring (39), so as to prevent some large pieces of mud from entering the filter press box (13) through the gap between the vibrating mud discharge plate (40) and the inner side surface of the second delivery channel, thereby blocking the upper and lower filter belts (34) and affecting the filtration effect of the filter press; The density of the mud discharge port (41) at the center of the vibrating mud discharge plate (40) is greater than the density of the mud discharge port (41) at the edge of the vibrating mud discharge plate (40), and the number of the vibration motors (42) at the center of the vibrating mud discharge plate (40) is greater than the number of the vibration motors (42) at the edge of the vibrating mud discharge plate (40).

More vibration motors (42) and mud discharge ports (41) are more conducive to the vibration crushing and discharge of the sludge, thereby improving the vibration crushing efficiency of the sludge. The mud discharge port (41) is designed with a coarse inlet and a fine outlet. The funnel-shaped mud discharge port (41) is more conducive to the discharge of mud and reduces the blockage of the mud discharge port (41). At the same time, the fine outlet can prevent large pieces of mud from directly passing through the mud discharge port (41) into the filter press box (13) and affecting the filtration effect of the filter press. The inner wall of the mud discharge port (41) is designed to be a smooth structure, which is more conducive to the discharge of mud from the mud discharge port (41) and reduces the amount of mud remaining in the mud discharge port (41); The vibration motor (42) is designed to be started once every half an hour, so that the vibration motor (42) does not need to be in a working state all the time, which can save energy; and starting it once every half an hour can also ensure that some large pieces of sludge enter the filter press box (13) from the sludge discharge port (41) on the vibration sludge discharge plate (40); The vibration motor (42) is used to vibrate the vibrating mud discharge plate (40), so that large pieces of sludge falling on the vibrating mud discharge plate (40) are crushed and then enter the filter press box (13) through the mud discharge port (41), thereby crushing the large pieces of sludge and improving the filtration effect of the filter press.

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.

[0019] The flocculation component can be used to make the sewage and the flocculant fully contact, so that more sludge is produced after flocculation.
