[0002] In the process of sewage treatment, in order to remove suspended matter in sewage, a sedimentation tank is used to separate the solid and liquid of sewage. After the sedimentation tank has been used for a period of time, a large amount of sludge will be deposited at the bottom, so a scraper is needed to automatically clean it. There are many types of scrapers, and a driving scraper is one of them. It can effectively improve the sewage treatment effect of the staff.

[0003] When using a traveling scraper for cleaning, since the sewage sedimentation tank needs to settle for a certain period of time before it can be cleaned, some sludge will condense into mud blocks after a long period of sedimentation. The resistance of the agglomerated sludge is relatively large, making it difficult to be scraped by the scraper, causing the scraper to get stuck during the movement, which will affect the normal cleaning of the sludge tank. For this reason, we propose a sedimentation tank scraper device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A sedimentation tank scraper device comprises a sedimentation tank body 1, a mud collecting bucket 2 is provided at the bottom end of the sedimentation tank body 1, and a mud discharge pipe 3 is connected to the side of the mud collecting bucket 2. When in use, the staff can scrape the sludge deposited on the inner wall of the bottom end of the sedimentation tank body 1 into the interior of the mud collecting bucket 2 for centralized treatment, and the treatment method of the sludge inside the mud collecting bucket 2 is the existing technology, which will not be described in detail here. A moving component 4 is installed at the top of the sedimentation tank body 1, and a first cylinder 5 is distributed at the center position of the moving component 4. The moving component 4 is driven by a driving driver to move, and its specific walking principle is the existing technology, which will not be described in detail here. It can drive the scraper plate 6 to move left and right inside the sedimentation tank body 1 to In order to achieve the purpose of scraping mud, the bottom end of the first cylinder 5 is connected to the scraper plate 6 through a vertical rod, and a mounting plate 7 is distributed on the side of the scraper plate 6, a motor 8 is connected to the center position of the upper side of the mounting plate 7, and the output end of the motor 8 extends to the bottom of the mounting plate 7 and is connected to the first rotating shaft 9, a bevel gear set 10 is sleeved on the outer side of the first rotating shaft 9, and second rotating shafts 11 are symmetrically distributed on both sides of the bevel gear set 10, and mud crushing knives 12 are equidistantly sleeved on the outer surface of the second rotating shaft 11, and the bevel gear set 10 is composed of three groups of bevel gears, two groups of bevel gears are sleeved on the ends of the two groups of second rotating shafts 11 close to each other, and the other group of bevel gears is sleeved on the outer side of the first rotating shaft 9.

[0023] Further, see Figure 3It can be known that the upper side of the scraper blade 6 is symmetrically connected to the support plate 14, and the support plate 14 is set to an L-shaped structure. The second cylinder 15 is installed on the inner side of the support plate 14, and the bottom end of the second cylinder 15 is connected to the mounting plate 7. Due to the limited length of the first cylinder 5, the upward movement of the scraper blade 6 driven by it is relatively short. In the process of the scraper blade 6 moving upward, the support plate 14 set in the L-shaped structure will not collide with the moving component 4. Through the mutual cooperation of the second cylinder 15 and the support plate 14, the mounting plate 7 can be driven to move up and down as a whole, so that multiple groups of mud crushers 12 can move up and down and comprehensively disperse the sludge, thereby effectively improving the dispersion effect of the sludge. The specific telescopic principle of the first cylinder 5 and the second cylinder 15 is the existing technology, which will not be described in detail here. The second cylinder 15 has better waterproof performance and can be used normally inside the sedimentation tank body 1.

[0024] Further, see Figure 3 It can be known that the sides of the second rotating shaft 11 that are away from each other are respectively provided with mounting sleeves 19 through bearing sleeves, and the tops of the mounting sleeves 19 are connected to the mounting plate 7 through connecting rods. Through the rotational connection between the mounting sleeves 19 and the second rotating shaft 11, and in conjunction with the setting of the connecting rod, the stability of the two groups of second rotating shafts 11 during rotation can be effectively guaranteed.

[0025] Further, see Figure 3 and Figure 4 It can be known that a protective cover 13 is provided on the outer side of the bevel gear set 10, and a rotating groove matched with the second rotating shaft 11 is opened inside the protective cover 13, the outer wall of the protective cover 13 is fixedly connected to the mounting plate 7, and the two sets of second rotating shafts 11 are respectively connected to the inner wall of the rotating groove through the bearing. By setting the protective cover 13, the bevel gear set 10 can be covered and protected to ensure the normal use of the bevel gear set 10.

[0026] Further, see Figure 3 It can be known that a fixing plate 16 is distributed on the side of the mounting plate 7, and a steel brush 17 is equidistantly distributed on the other end of the fixing plate 16. The steel brush 17 fits tightly against the side of the scraper blade 6. When in use, the right side of the scraper blade 6 can be cleaned by the setting of the fixing plate 16 and the steel brush 17 and driven by the second cylinder 15 to ensure the scraping effect of the scraper blade 6.

[0027] Further, see Figure 3 It can be known that the upper side of the fixed plate 16 is symmetrically connected with the docking plate 18, and the lower side of the docking plate 18 is in contact with the mounting plate 7. The interior of the docking plate 18 is connected to the mounting plate 7 by bolts. Through the mutual cooperation of the docking plate 18 and the bolts, it is convenient for the staff to remove the damaged steel brush 17 during the maintenance process.

[0028] Further, see Figure 3 It can be seen that grooves are equidistantly provided at both ends of the mounting plate 7, and balls are installed inside the grooves. The balls and grooves are not shown in the figure. By setting up multiple groups of balls, the smoothness of the mounting plate 7 during the up and down movement can be effectively guaranteed, thereby reducing the wear on the ends of the mounting plate 7.

[0029] Working principle: When the utility model is in use, the staff can first transport the sewage to be treated to the interior of the sedimentation tank body 1 for sedimentation treatment. After a period of sedimentation, the sludge will accumulate on the inner wall of the bottom end of the sedimentation tank body 1. At this time, the staff can use the mobile component 4 driven by the driving driver to travel along the track above the sedimentation tank body 1. During the movement of the mobile component 4, the scraper plate 6 can be driven to scrape the sludge at the bottom end of the sedimentation tank body 1. During the process of the scraper plate 6 scraping the sludge, the motor 8 is driven, thereby driving the continuous rotation of the first rotating shaft 9. In conjunction with the bevel gear set 10 sleeved on the outer side of the first rotating shaft 9, the two sets of second rotating shafts 11 can be driven to rotate in an annular manner. Since the outer side of the second rotating shaft 11 is sleeved with a mud crusher 12, the agglomerated sludge can be broken up and dispersed. In addition, during the process of the mud crusher 12 breaking the sludge, the second rotating shaft 11 can be driven to rotate continuously. , the second cylinder 15 is started intermittently, thereby driving the mounting plate 7 to move up and down intermittently as a whole, so that multiple groups of mud crushers 12 can be broken up and down at the same time, which can effectively improve the dispersion effect of the sludge. In addition, during the up and down process of the mounting plate 7, the steel brush 17 connected to the side of the fixed plate 16 can scrape the scraper plate 6, thereby cleaning the sludge attached to the outside of the scraper plate 6. After scraping the sludge into the mud collecting bucket 2, the staff can drive the scraper plate 6 to lift up slightly through the first cylinder 5, so that the scraper plate 6 no longer abuts against the inner wall of the bottom end of the mud collecting bucket 2, and then by moving the moving component 4 to the left, the scraper plate 6 can be driven to move to the left as a whole, and the sludge inside the mud collecting bucket 2 can be treated by the staff through chemical methods or grabbing buckets. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
