Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to an automatic feeding device. Background Art

[0002] Sludge refers to the sediment, particulate matter and floating matter produced during the sewage treatment process. Sludge is mainly composed of organic matter, bacterial cells, etc. It is a complex heterogeneous body. Sludge treatment refers to the process of treating and disposing of the sludge produced during the sewage treatment process. Sludge is solid waste that precipitates or floats during the sewage treatment process, containing organic matter, inorganic matter, microorganisms and other components. The main purpose of sludge treatment is to reduce the volume, stabilize harmful substances, reduce pollutant emissions, and realize resource utilization.

[0003] The utility model patent with the authorization announcement number: CN216481012U discloses an automatic feeding device for sludge treatment, which involves a chain conveyor. A frame can be detachably installed on the chain conveyor, and a feeding end is fixedly connected to the frame. A control component for adjusting the opening size of the feeding end is arranged inside the feeding end. A scraper plate that moves up and down is arranged on one side of the frame, and a sleeve is fixedly connected to the upper end surface of the scraper plate. A threaded rod 1 is matched with the internal thread of the sleeve, and a hand wheel is fixedly connected to one end of the threaded rod 1. One end of the hand wheel passes through the frame, and the hand wheel and the frame rotate in cooperation. Limiting components are symmetrically arranged on both sides of the sleeve, and the two ends of the limiting components are fixedly connected to the upper end surface of the scraper plate and the side of the frame respectively. The utility model has a reasonable structure and solves the problem of sludge accumulation during transportation.

[0004] Regarding the above scheme: the reference document uses a chain conveyor to transport and load the sludge, and uses a scraper plate and a baffle plate to limit the sludge, so that the sludge can be smoothly transported by the chain conveyor. However, when the chain conveyor is transporting the sludge, the sludge is not easy to fall completely from the upper side of the chain conveyor, and some of the sludge will adhere to the outside of the chain conveyor. After a long time, the sludge originally adhered to the outside of the chain conveyor will easily solidify on the outside of the chain conveyor due to the increase in time. This will not only gradually reduce the sludge that the chain conveyor can transport, but also make it more troublesome and inconvenient to clean the chain conveyor later. Utility Model Content

At the same time, the first limit plate 36 is used to limit the sludge, thereby reducing the possibility of the sludge falling or sliding from the upper side of the chain conveyor 1. The cleaning mechanism 4 can effectively scrape off the sludge that has not been fed and is adhered to the outside of the chain conveyor 1, thereby reducing the sludge adhered to the outside of the chain conveyor 1. At the same time, the wetting mechanism 5 can humidify the sludge scraped by the cleaning mechanism 4, so that the sludge is not easy to dry out due to long-term collection, so that the collected sludge is also convenient to fill and take out during subsequent feeding and loading.

[0028] See also Figure 1-6 The cleaning mechanism 4 includes a connecting plate 41 arranged on one side of the chain conveyor 1, and a mounting groove 42 is opened on the upper side of the connecting plate 41.

The connecting plate 41 can play a role in installing and connecting the first servo motor 43, the second one-way screw 44 and the threaded block 45 through the mounting groove 42;

[0029] In addition, the first servo motor 43 can drive the second one-way screw 44 to rotate through its own operation, and the connecting plate 41 can also limit the threaded block 45 through the mounting groove 42, so that when the first servo motor 43 is in operation, it can smoothly drive the threaded block 45 to move, and the threaded block 45 can be connected to the connecting block 47 through the electric telescopic rod 46, and due to the connection between the connecting block 47 and the scraper 48, the threaded block 45 can drive the scraper 48 to move together when moving, and through the electric telescopic rod The operation of the rod 46 drives the scraper 48 to move up and down, thereby adjusting the height of the scraper 48.

[0031] See also Figure 1-4 : A second servo motor 61 is connected to one side of the moistening box 51, and the output shaft of the second servo motor 61 passes through the moistening box 51. The output shaft of the second servo motor 61 is connected to a connecting rod 64 through a coupling, and one end of the connecting rod 64 is connected to a cam 62. A connecting ring block 63 is connected to the lower side of the water tank 52, and the cam 62 is arranged on the outer side of the connecting ring block 63. The second servo motor 61 can be connected to the cam 62 through the connecting rod 64, and the second servo motor 61 can smoothly drive the cam 62 to rotate when it is in operation. The water tank 52 can be connected to the connecting ring block 63. When the cam 62 passes through the second servo motor 61, the cam 62 is rotated. When the operation is rotating, the connecting ring block 63 and the water tank 52 can be pushed smoothly, so that the water tank 52 can move up and down. When the water tank 52 moves up and down and moves to the lowermost side, it is not easy for the water pipe 53 to extract the water source inside the water tank 52. This allows the atomizing nozzle 55 to spray the water source intermittently, so that the sludge collected in the collecting box 49 is not easy to increase its fluidity due to the long-term spraying of the atomizing nozzle 55, and the sludge collected in the collecting box 49 is not easy to flow from the upper side of the chain conveyor 1 due to excessive fluidity during the secondary filling.

[0034] See also Figure 1-6 : Baffles 9 are connected to both sides of the collecting plate 410, and a reinforcement ring block 10 is connected to the lower side of the connecting block 47. The reinforcement ring block 10 is connected to the outer side of the top of the electric telescopic rod 46. The baffle 9 can play a certain limiting role on the sludge collected and guided by the collecting plate 410, so that the sludge is not easy to slide from the two sides of the collecting plate 410, and the reinforcement ring block 10 can strengthen the stability of the connection between the electric telescopic rod 46 and the connecting block 47 through the connection between itself, the electric telescopic rod 46 and the connecting block 47, so that the connecting block 47 and the scraper 48 can be sufficiently firm and stable when in use.

[0035] See also Figure 4: A sliding rod 72 is connected to the lower side of the water tank 52, and a limiting hollow rod 71 is connected to the inner side of the wetting box 51. The sliding rod 72 is arranged on the inner side of the limiting hollow rod 71. The water tank 52 can be connected to the sliding rod 72, and the wetting box 51 can be connected to the limiting hollow rod 71. The limiting hollow rod 71 can limit the water tank 52 through the sliding rod 72. This makes it difficult for the water tank 52 to tilt when it moves up and down through the rotation of the cam 62, thereby increasing the stability of the water tank 52 when it moves up and down.

[0036] See also Figure 4 A card slot 82 is provided on one side of the collecting box 49, and a card plate 81 is connected to one side of the wetting box 51, and the card plate 81 is arranged on the inner side of the card slot 82. The wetting box 51 can install and connect the card plate 81, and after the card plate 81 is connected to the inner side of the card slot 82, the collection box 49 and the wetting box 51 can be connected. This allows the wetting box 51 to be smoothly disassembled and placed separately when it is not needed, and it is also convenient enough when water needs to be added. At the same time, it also makes the installation and disassembly of the wetting box 51 convenient enough.

[0037] See also Figure 5 and Figure 7 : A rotating rod 111 is connected to one side of the adjusting plate 31, one end of the rotating rod 111 passes through the filling bin 2, a gear 112 is connected to the outer side of the rotating rod 111, a mounting plate 113 is connected to one side of the filling bin 2, a pull rod 114 is connected to the inner side of the mounting plate 113, one end of the pull rod 114 is connected to a rack 116, a spring 115 is connected between the mounting plate 113 and the rack 116, and the spring 115 is sleeved on the outer side of the pull rod 114, one side of the rack 116 is meshed with the outer side of the gear 112, the rotating rod 111 can connect the adjusting plate 31 with the filling bin 2, and the rotating rod 111 can also play a role in installing and fixing the gear 112;

[0038] In addition, the filling bin 2 can be connected to the tie rod 114 through the mounting plate 113, and the tie rod 114 can cooperate with the mounting plate 113 to install the spring 115 while installing the rack 116. When the rack 116 is engaged with the gear 112, the mounting plate 113 connects and limits the tie rod 114, which enables the rack 116 to smoothly limit the gear 112, making it difficult for the rotating rod 111 and the adjusting plate 31 to rotate. When the angle of the adjusting plate 31 needs to be adjusted, When the sludge discharge speed is controlled, the staff can pull the pull rod 114 so that the rack 116 no longer meshes with the gear 112, and then the angle of the adjustment plate 31 can be adjusted by rotating the rotating rod 111. When the adjustment is completed, it is only necessary to release the pull on the pull rod 114 so that the rack 116 can be reset by the elasticity of the spring 115 and mesh with the gear 112 again, so as to limit the rotating rod 111 and the adjustment plate 31 again, thereby making the angle adjustment of the adjustment plate 31 more convenient and simple.

[0039] It should be noted that: one side of the baffle 9 is screwed to the collecting plate 410, the upper side of the reinforcing ring block 10 is screwed to the connecting block 47, the inner side of the reinforcing ring block 10 is screwed to the top of the electric telescopic rod 46, one side of the card plate 81 is screwed to the wetting box 51, the outer side of the card plate 81 is movably connected to the collecting box 49 through the card slot 82, the upper end of the slide rod 72 is screwed to the water tank 52, the lower side of the limit hollow rod 71 is screwed to the wetting box 51, the outer side of the slide rod 72 is slidably connected to the limit hollow rod 71, and the rotation One end of the rod 111 is slidably mounted on the filling bin 2, the outer side of the rotating rod 111 is screwed to the adjusting plate 31, the inner side of the gear 112 is screwed to the rotating rod 111, one side of the mounting plate 113 is screwed to the filling bin 2, the outer side of the pull rod 114 is slidably inserted into the mounting plate 113, one end of the pull rod 114 is screwed to the rack 116, one side of the rack 116 is meshed with the gear 112, one end of the spring 115 is welded to the mounting plate 113, and the other end of the spring 115 is welded to the rack 116.

[0040] Working principle: When the utility model is used, the staff can place the connecting plate 41 on one side of the chain conveyor 1, and adjust the position of the scraper 48 according to the height of the chain conveyor 1. When adjusting, the staff can start the first servo motor 43, and drive the second one-way screw 44 to rotate through the operation of the first servo motor 43, so that the threaded block 45 can smoothly drive the electric telescopic rod 46, the connecting block 47 and the scraper 48 to move, and then adjust the height of the scraper 48 through the operation of the electric telescopic rod 46. After the scraper 48 moves to the appropriate position, the scraper 48 can smoothly scrape off the sludge adhered to the outside of the chain conveyor 1, and the scraped sludge will fall to the upper side of the collecting plate 410, and slide through the collecting plate 410 to the inside of the collecting box 49, and be temporarily collected by the collecting box 49.

[0041] At the same time, the second servo motor 61 will drive the cam 62 to rotate through its own operation, and drive the water tank 52 to move up and down through the rotation of the cam 62. When the water tank 52 moves up and down, the water pump 54 can pump water into the interior of the atomizing nozzle 55 through the water pipe 53 to spray the sludge collected in the collection box 49. Due to the up and down movement of the water tank 52, the spraying of the atomizing nozzle 55 will be intermittent, so that the sludge can be kept moist without increasing its fluidity due to excessive addition of water.
