Description

Technical Field

[0001] The present invention discloses a reciprocating double-scraper residual mud cleaning structure for a filter press and a filter press, which relates to a structure capable of cleaning the residual sludge on the inner side surface of a second mud conveying channel of the filter press, and belongs to the technical field of sewage treatment, and particularly to a structure capable of cleaning the residual sludge on the inner side surface of the second mud conveying channel by driving a pull rope to rotate through a sixth rotating motor, and the pull rope drives a sliding rib, a first scraper and a second scraper to move up and down along a sliding groove. 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". The flocculated sludge is subjected to a first dehydration treatment through a transmission component. The sludge after the first dehydration treatment enters the first mud channel from the other end of the transmission pipe under the action of gravity, enters the second mud channel from the first mud channel, and enters the filter press box from the second mud channel. After long-term use, a lot of sludge will remain on the inner side of the second mud channel, forming stubborn sludge, which may cause the second mud channel to be blocked, making it impossible for the sludge to enter the subsequent filtration link. However, the above-mentioned filter press cannot perform regular self-cleaning on the inner side of the second mud channel, which will affect the sludge treatment effect. Summary of the invention

A sixth rotating motor (46) is disposed on the inner bottom surface of the support plate (19). A fixing block (42) is disposed on the inner bottom surface of the support plate (19), and one side surface of the fixing block (42) is disposed on an inner side surface of the support plate (19). One end of the main shaft (44) is placed on the other side of the fixed block (42) through a bearing. The other end of the main shaft (44) is connected to the rotating shaft of the sixth rotating motor (46). One end of the pull rope (43) is wound around the main shaft (44). Preferably, the outer layer of the pull rope (43) is made of braided wear-resistant fiber material. A sliding groove (41) is formed on each inner side surface of the second mud conveying channel (12); the height of the sliding groove (41) is equal to the height of the main shaft (44); the depth of the sliding groove (41) is less than the thickness of the second mud conveying channel (12); One end of the sliding rib (47) is slidably disposed in the corresponding sliding groove (41). Preferably, the edge of the sliding rib (47) is a rounded structure. The first scraper (39) comprises three parts: a connecting column, a connecting plate and a scraping blade. There are a plurality of the first scrapers (39), each of which corresponds to an inner side surface of the second mud conveying channel (12). The plurality of first scrapers (39) are connected end to end via the connecting column. The top surface of the connecting plate is vertically placed at the bottom of the side of the connecting column, the bottom surface of the connecting plate is vertically placed at the middle of the top surface of the scraping blade, the length of the connecting plate is equal to the length of the connecting column, and the length of the scraping blade is equal to the length of the connecting plate. Preferably, the width of the scraper blade gradually decreases from the top surface to the bottom surface. Preferably, the scraping blade is a hollow structure. Preferably, a rubber sheet is detachably disposed on the bottom surface of the scraping blade, and the length of the rubber sheet is equal to the length of the scraping blade. The bottom surface of the scraper blade is slidably disposed on each inner side surface of the second mud conveying channel (12); the length of the scraper blade is equal to the length of the corresponding inner side surface of the second mud conveying channel (12). The other end of the sliding rib (47) is connected to the middle part of the side surface of the connecting column. A rope limiting groove (48) is provided on the side of the connecting column close to the sixth rotating motor (46), and the rope limiting groove (48) is close to the middle of the connecting column. The other end of the pull rope (43) passes through a through hole opened in the second mud conveying channel (12) and is placed in the rope limiting groove (48). A second scraper (40) is disposed on the side of the scraper blade, the second scraper (40) is close to the top surface of the scraper blade, the second scraper (40) is away from the sliding rib (47), and the angle between the side of the scraper blade and the inner side of the second mud conveying channel (12) is greater than 90 degrees. Preferably, the side of the scraper blade is coated with an anti-stick lubricant. Preferably, the second scraper (40) is an arc-shaped structure, and the height of the second scraper (40) gradually decreases from the center to both ends. Preferably, there are a plurality of the second scrapers (40), and the plurality of the second scrapers (40) are arranged without spacing along the length direction of the scraper. Preferably, the second scraper (40) is a structure with one end bent in multiple arc shapes toward the other end. When in use, the scraping structure replaces the second mud conveying channel (12) in the filter press, and the flocculated sludge is subjected to a first dehydration treatment through the transmission component. The sludge after the first dehydration treatment enters the first mud conveying channel (11) from the other end of the transmission pipe (6) under the action of gravity, and enters the second mud conveying channel (12) from the first mud conveying channel (11). The sixth rotating motor (46) is started to rotate forward or reverse. When rotating forward, the sixth rotating motor (46) drives the pull rope (43) to rotate, and the pull rope (43) has a pulling effect on the sliding rib (47) and the first scraper (39). The sliding rib (47) and the first scraper (39) slide downward along the sliding groove (41) under the action of gravity. When rotating reversely, the sixth rotating motor (46) drives the pull rope (43) to rotate. The pull rope (43) has a pulling effect on the sliding rib (47) and the first scraper (39). The sliding rib (47) and the first scraper (39) slide downward along the sliding groove (41) under the action of gravity. The machine (46) drives the pull rope (43) to rotate, and the pull rope (43) drives the sliding rib (47) and the first scraper (39) to slide upward along the sliding groove (41), and this process is repeated. The scraper on the first scraper (39) scrapes away the sludge remaining on the inner side surface of the second sludge conveying channel (12). A portion of the scraped sludge directly enters the filter press box (13) under the action of gravity, and another portion of the scraped sludge accumulates on the scraper and enters the second scraper (40). Under the blocking and guidance of the second scraper (40), the sludge enters the filter press box (13) under the action of gravity, so that the sludge remaining on the inner side surface of the second sludge conveying channel (12) can be cleaned, thereby reducing the formation of stubborn sludge and preventing the second sludge conveying channel (12) from being blocked. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: an arc-shaped groove (49) is formed at the bottom of the sliding groove (41); the width of the arc-shaped groove (49) is equal to the width of the sliding groove (41); and the height of the arc-shaped groove (49) gradually decreases from one end to the other end; when in use, when the first scraper (39) scrapes the sludge remaining on the inner side of the second sludge conveying channel (12), a part of the scraped sludge will enter the sliding groove (41); the arc-shaped groove (49) can help the sludge to enter the filter press box (13) from the bottom of the sliding groove (41), thereby preventing the sludge from accumulating at the bottom of the sliding groove (41) and affecting the sliding of the sliding rib (47) in the sliding groove (41); Example 3

[0015] The difference between this embodiment and embodiment 1 is that: a circular arc flow guide opening (50) is formed at the connection between two adjacent inner side surfaces of the second mud conveying channel (12), and the height of the circular arc flow guide opening (50) is equal to the height of the second mud conveying channel (12); when in use, the sludge that has undergone the primary dehydration treatment enters the second mud conveying channel (12), and the circular arc flow guide opening (50) can help the sludge enter the filter press box (13), thereby reducing the amount of sludge remaining in the four corners of the second mud conveying channel (12); The support plate (19) is designed as a U-shaped structure, so that the support plate (19) has high strength and stability, can effectively support and disperse pressure, and can protect the sixth rotating motor (46) and the fixed block (42) on the support plate (19), thereby preventing the fixed block (42) and the sixth rotating motor (46) from falling off the support plate (19) due to vibration of the sixth rotating motor (46); The outer layer of the pull rope (43) is designed to be made of a braided wear-resistant fiber material, which can improve the wear resistance of the pull rope (43), reduce the wear of the pull rope (43) after long-term use, and extend the service life of the pull rope (43); The edge of the sliding rib (47) is designed with a rounded structure, which can reduce the friction force when the sliding rib (47) slides in the sliding groove (41), prevent the sharp corner of the sliding rib (47) from getting stuck in the sliding groove (41), reduce the blocking phenomenon, and make the sliding effect of the sliding rib (47) better; The design of the scraper blade gradually decreasing in width from the top surface to the bottom surface makes the bottom surface of the scraper blade sharper and the contact area with the inner surface of the second sludge conveying channel (12) smaller, thereby reducing friction, making it easier to move and scrape away residual sludge, and making the bottom surface of the scraper blade more evenly worn, thereby extending the service life of the scraper blade; The scraper blade is designed with a hollow structure, which can reduce the weight of the scraper blade. When the sixth rotary motor (46) is reversed, the weight of the first scraper (39) attached to the pull rope (43) can be reduced, making it easier for the sliding rib (47) and the first scraper (39) to slide upward along the sliding groove (41); A rubber sheet is detachably disposed on the bottom surface of the scraping blade. The length of the rubber sheet is designed to be equal to the length of the scraping blade. The rubber sheet can increase the friction between the scraping blade and the inner wall of the second mud conveying channel (12), thereby preventing the scraping blade from falling too fast and being damaged by a hard collision at the bottom.

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. 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.
