Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: a tap water pretreatment device, including a sedimentation tank 1, a scraping device 2, and a cleaning device 3.

[0019] Reference Figure 1 In this embodiment, the sedimentation tank 1 is preferably a rectangular sedimentation tank, and the sedimentation tank 1 is installed at a predetermined position on the ground. The sedimentation tank 1 has an installation groove 11 and a receiving groove on both sides of its long side. The inner cavities of the installation groove 11 and the receiving groove are connected. The long side of the installation groove 11 is parallel to the long side of the sedimentation tank 1, and both the installation groove 11 and the receiving groove are close to the bottom of the sedimentation tank 1.

[0020] Reference Figure 1 The sedimentation tank 1 has an inlet 12 and an outlet 13 on the two side walls at both ends of the long side direction, and both the inlet 12 and the outlet 13 are located at the top of the sedimentation tank 1. The horizontal plane at the opening end of the sedimentation tank 1 is designated as the top wall. The side walls on both sides of the sedimentation tank 1 in the long side direction are called the inner side walls, and the side walls at both ends of the long side direction are called the inner walls.

[0021] Reference Figure 1 The bottom of the two side walls of the sedimentation tank 1, which are equipped with an inlet 12 and an outlet 13, are arc-shaped with the bottom of the sedimentation tank 1.

[0022] Reference Figure 1 and Figure 2The scraping device 2 is installed in the mounting groove 11. The scraping device 2 includes a drive assembly 21. The drive assembly 21 is provided in two sets, and the two sets of drive assemblies 21 are respectively on both sides of the axial direction of the water inlet 12.

[0023] Reference Figure 1 and Figure 2 The drive assembly 21 includes a first motor 211, a sprocket 212, and a chain 213. In this embodiment, the first motor 211 is preferably a servo motor. The first motor 211 is located in the receiving groove. The housing of the first motor 211 is fixedly connected to the sedimentation tank 1 by screws. A seal is provided at the output shaft of the first motor 211, and the seal is sandwiched between the output shaft of the first motor 211 and the sedimentation tank 1. In this embodiment, there are two sprockets 212, which are located at both ends of the long side of the mounting groove 11. The sprocket 212 closer to the first motor 211 is coaxially fixedly connected to the output shaft of the first motor 211 by a key connection. The other sprocket 212 is rotatably connected to the sedimentation tank 1 by a rotating shaft connection. The chain 213 is wound around the two sprockets 212, and the chain 213 and the sprockets 212 are engaged.

[0024] Here, the end face of the chain 213 away from the axis of rotation is the outer peripheral wall. The first motor 211 drives the sprocket 212 to rotate, which in turn drives the sprocket 212 to rotate, so that the chain 213 can rotate along the sedimentation tank 1.

[0025] Reference Figure 1 and Figure 2 The scraping device 2 also includes multiple scraping components 22, which are arranged at intervals along the long side of the chain 213. Each scraping component 22 includes a mounting plate 221 and an assembly 222. In this embodiment, the mounting plate 221 is preferably a rectangular strip. The mounting plate 221 is horizontally arranged, and the long side of the mounting plate 221 is perpendicular to the long side of the sedimentation tank 1. In this embodiment, the assembly 222 is preferably a connecting shaft. There are two assemblies 222, which are located at the two ends of the long side of the mounting plate 221, respectively. The assemblies 222 and the chain 213 are fixedly connected at corresponding positions.

[0026] Reference Figure 1 and Figure 2The scraping assembly 22 also includes a counterweight plate 223 and a scraper 224. In this embodiment, the counterweight plate 223 is preferably a rectangular strip plate. The counterweight plate 223 is located on the bottom wall of the mounting plate 221, and the long side of the counterweight plate 223 is parallel to the long side of the mounting plate 221. The counterweight plate 223 is fixedly connected to the mounting plate 221 by screws. The scraper 224 is located on the side of the counterweight block near the discharge port. In this embodiment, the scraper 224 is preferably a right-angled triangular plate. One right-angled side of the scraper 224 is attached to the counterweight plate 223, and the other right-angled side is attached to the bottom wall of the sedimentation tank 1. The scraper 224 is fixedly connected to the counterweight plate 223 by screws.

[0027] Mounting plate 221 is fixed to the corresponding structure of chain 213 by assembly 222. The setting of counterweight plate 223 enables scraper 224 to always be in contact with the bottom wall of sedimentation tank 1, and scraper 224 to clean the sludge at the bottom of sedimentation tank 1.

[0028] Reference Figure 1 and Figure 3 The cleaning device 3 includes a pushing assembly 23, which is installed below the outlet 13 of the sedimentation tank 1. The pushing assembly 23 includes a second motor 231, a screw 232, and a pushing plate 233. In this embodiment, the second motor 231 is preferably a servo motor, and the second motor 231 has a waterproof structure. The housing of the second motor 231 is fixedly connected to the sedimentation tank 1 by screws, and the output shaft axis of the second motor 231 is parallel to the long side of the mounting plate 221. The screw 232 is coaxially fixedly connected to the output shaft of the second motor 231 by a coupling. The side wall of the pushing plate 233 is attached to the side wall of the sedimentation tank 1, and the pushing plate 233 is provided with a screw nut. The pushing plate 233 is threadedly connected to the screw 232 by the screw nut.

[0029] Reference Figure 1 and Figure 4 In this embodiment, the pusher plate 233 is a right-angled trapezoidal plate, wherein the bottom wall of the pusher plate 233 is attached to the bottom wall of the sedimentation tank 1, and the side wall of the pusher plate 233 can be attached to the side wall of the scraper plate 224.

[0030] The operator drives the second motor 231 to rotate the screw 232. The screw 232 meshes with the pusher plate 233, thereby causing the pusher plate 233 to slide along the screw 232. Then, the pusher plate 233 scrapes the sludge from the bottom of the sedimentation tank 1 and the side wall of the scraper plate 224.

[0031] Reference Figure 1 and Figure 4The side wall of the sedimentation tank 1 is provided with a sludge outlet 14 in the vertical direction, and the bottom of the sludge outlet 14 is connected to the inner cavity of the sedimentation tank 1. In this embodiment, the sludge outlet 14 is preferably a circular groove.

[0032] Reference Figure 1 and Figure 4 The inner cavity of the mud outlet 14 is provided with a material lifting assembly 31. The material lifting assembly 31 includes a connecting rod 311, a connecting piece 312 and a mud baffle 313. The connecting rod 311 and the output shaft of the second motor 231 are coaxially arranged. In this embodiment, the connecting piece 312 is preferably a one-way clutch. One end of the connecting rod 311 is rotatably connected to the sedimentation tank 1 by means of a bearing connection, and the other end is threadedly connected to the screw 232 by the connecting piece 312.

[0033] In this embodiment, when the second motor 231 drives the screw 232 to rotate, thereby causing the pusher plate 233 to slide closer to the mud outlet 14, the connecting member 312 drives the connecting rod 311 to rotate coaxially with the screw 232. When the second motor 231 drives the screw 232 to rotate, thereby causing the pusher plate 233 to slide away from the mud outlet 14, the connecting rod 311 cannot rotate with the screw 232.

[0034] Reference Figure 1 and Figure 4 The material lifting assembly 31 also includes a lifting blade 32, a first bevel gear 33, and a second bevel gear 34. In this embodiment, the lifting blade 32 is preferably a threaded blade and is coaxially arranged with the mud outlet 14. The lifting blade 32 is rotatably connected to the sedimentation tank 1 by means of a bearing connection. The first bevel gear 33 and the second bevel gear 34 are located below the mud baffle 313. The first bevel gear 33 and the connecting rod 311 are coaxially fixedly connected by means of a key connection. The second bevel gear 34 and the lifting blade 32 are coaxially fixedly connected, and the first bevel gear 33 and the second bevel gear 34 mesh.

[0035] Reference Figure 1 and Figure 4 The cleaning device 3 also includes a sludge remover 35, which is installed in the sedimentation tank 1 at the sludge outlet 14. The scraper of the sludge remover 35 is attached to the top of the lifting blade 32. The scraper is used to scrape off the sludge from the lifting blade 32. A feeding trolley is provided below the end of the sludge remover 35 that is away from the lifting blade 32.

[0036] Therefore, when the pusher plate 233 is close to the mud outlet 14, the lifting blade 32 rotates to carry out the sludge. When the pusher plate 233 is far away from the mud outlet 14, the lifting blade 32 stops rotating and cannot lift out the sludge.

[0037] The removed sludge is moved away from the sludge outlet 14 by the sludge remover 35, thus completing the corresponding sludge cleaning operation.

[0038] The implementation principle of a tap water pretreatment device is as follows: the operator first transfers the water to be treated to the sedimentation tank 1 through the water inlet 12.

[0039] The first motor 211 drives the sprocket 212 to rotate, which in turn drives the chain 213 to rotate. The chain 213 drives the mounting plate 221 to rotate, and the mounting plate 221 drives the scraper 224 to clean the bottom wall of the sedimentation tank 1.

[0040] Then, the second motor 231 drives the screw 232 to rotate, and the screw 232 drives the pusher plate 233 to slide, thereby cleaning the sludge on the scraper plate 224 and the bottom of the sedimentation tank 1. Then, the connecting rod 311 is driven to rotate through the connecting piece 312, and the lifting blade 32 pushes the sludge at the sludge outlet 14 to the end of the sludge outlet 14, thereby completing the cleaning of the sludge.
