[0002] Flocculation and sedimentation treatment is a common water treatment technology that uses flocculants to cause suspended particles in water to coagulate and precipitate, thereby achieving the purpose of water purification. Flocculation and sedimentation treatment refers to the process of adding coagulants (i.e. flocculants) to water to cause the colloids and dispersed particles of suspended matter in the water to form flocs under the interaction of molecular forces. During the sedimentation process, the particles collide and coagulate with each other, and their size and mass continue to increase, and eventually settle to the bottom.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention provides a flocculation and sedimentation treatment device for waste sludge, including a stirring box 1 and a treatment box 4. For example, Figure 1-Figure 7 shown.

[0029] A cover plate 2 is provided on the upper side of the mixing box 1, and a feeding pipe 31 and a feeding pipe 32 are fixedly connected to the inner side of the cover plate 2. A stirring mechanism 6 is provided on the inner side of the mixing box 1. A connecting pipe 33 is fixedly connected to the interior of the mixing box 1, and a water pump 34 is provided on the outer side of the connecting pipe 33. One end of the connecting pipe 33 is connected to the interior of the mixing box 1. A hollow groove 9 is provided on one side of the processing box 4, and a filter assembly 5 is provided on the inner side of the processing box 4. A reciprocating mechanism 8 is provided on the lower side of the filter assembly 5.

[0030] The reciprocating mechanism 8 includes a fixed block 81 fixedly connected to one side of the processing box 4, and a second servo motor 82 is fixedly connected to the inner side of the fixed block 81. The output end of the second servo motor 82 passes through the fixed block 81, and the output end of the second servo motor 82 is connected to a turntable 83 through a coupling transmission. The upper side of the turntable 83 is fixedly connected to a first fixed ring block 84.

[0031] A fixed plate 87 is fixedly connected to the inner side of the processing box 4, and a second mounting plate 85 is slidably connected to the upper side of the fixed plate 87. A second fixed ring block 86 is fixedly connected to the lower side of the second mounting plate 85. A rotating connecting rod 88 is provided on the outer side of the second fixed ring block 86 and the first fixed ring block 84, and the inner side of the rotating connecting rod 88 is rotatably connected to the second fixed ring block 86 and the first fixed ring block 84. The rotating connecting rod 88 is provided on the inner side of the hollow groove 9.

[0032] Specifically, the feed pipe 32 can be used to add slurry to the interior of the mixing tank 1, while the feeding pipe 31 can be used to add flocculant to the interior of the mixing tank 1. At the same time, when the water pump 34 is in operation, it can pump the flocculated slurry stirred by the stirring mechanism 6 into the inner side of the treatment tank 4 through the connecting pipe 33, so that it can be filtered by the filter assembly 5.

[0033] In addition, the fixed block 81 can be connected to the turntable 83 through the second servo motor 82, and when the second servo motor 82 is operating, it drives the turntable 83 to rotate. The rotation of the turntable 83 can drive the first fixed ring block 84 to rotate around the center of the turntable 83, and the processing box 4 can be connected to the second mounting plate 85 through the fixed plate 87. The rotating connecting rod 88 can be connected to the first fixed ring block 84 and the second fixed ring block 86. When the turntable 83 rotates, it drives the second mounting plate 85 to perform eccentric reciprocating motion, thereby realizing the reciprocating movement of the filter assembly 5, so that the mud filtered by the filter assembly 5 can be filtered more smoothly and is not easily accumulated or blocked on the inner side of the filter assembly 5.

[0034] The stirring mechanism 6 includes a first servo motor 61 fixedly connected to the upper side of the cover plate 2. The output end of the first servo motor 61 passes through the cover plate 2. Figure 1-Figure 7 shown.

[0035] A first mounting plate 62 is fixedly connected to the inner side of the mixing box 1, and a gear 63 is rotatably connected to the upper side of the first mounting plate 62, and the two gears 63 are meshed with each other. The output end of the first servo motor 61 is connected to one of the gears 63 through a coupling, and the lower sides of the two gears 63 are fixedly connected to a rotating rod 64, and the outer sides of the two rotating rods 64 are respectively fixedly connected to a first stirring plate 651 and a second stirring plate 652.

[0036] The filter assembly 5 includes a lower filter plate 53 disposed inside the second mounting plate 85 . A connecting hollow block 52 is disposed on the upper side of the lower filter plate 53 . An upper filter plate 51 is disposed on the upper side of the connecting hollow block 52 .

[0037] An insert block 101 is provided on the inner side of the second mounting plate 85 , and a slot 102 is fixedly connected to the lower side of the lower filter plate 53 . The slot 102 is movably engaged with the inner side of the insert block 101 .

[0038] Specifically, when the first servo motor 61 is in operation, it drives one of the gears 63 to rotate, and through the mutual engagement between the two gears 63, it drives the two rotating rods 64 to rotate in opposite directions. At this time, the first stirring plate 651 and the second stirring plate 652 can also rotate in opposite directions together. Therefore, through the opposite rotation of the first stirring plate 651 and the second stirring plate 652, the mud inside the stirring box 1 is stirred, so that the flocculant and the mud can be more fully mixed.

[0039] In addition, the connecting hollow block 52 can connect the upper filter plate 51 and the lower filter plate 53, and the upper filter plate 51 and the lower filter plate 53 can perform double filtering on the mud, thereby improving the filtering effect of the mud, and when the filter assembly 5 is removed, the upper filter plate 51 and the lower filter plate 53 can also be removed and cleaned together;

[0040] In addition, the arrangement of the plug 101 and the slot 102 makes it convenient and simple for the staff to connect or disassemble the second mounting plate 85 and the lower filter plate 53. At the same time, it also makes the filter assembly 5 relatively stable when moving back and forth through the reciprocating mechanism 8, and is not prone to shaking or falling.

[0041] The upper and lower sides of the connecting hollow block 52 are provided with connecting grooves 113, and the lower side of the upper filter plate 51 is fixedly connected to the first plug plate 111. Figure 1-Figure 7 shown.

[0042] The upper side of the lower filter plate 53 is fixedly connected to the second plug plate 112 , and the first plug plate 111 and the second plug plate 112 are movably plugged into the inner sides of the two connecting grooves 113 .

[0043] A sliding groove 131 is formed on the inner side of the processing box 4 , and a slide plate 132 is fixedly connected to one side of the second mounting plate 85 . The slide plate 132 is slidably connected to the inner side of the sliding groove 131 .

[0044] A discharge pipe 71 is fixedly connected to the inner side of the processing box 4 , a one-way valve 72 is provided on the outer side of the discharge pipe 71 , and a baffle 12 is provided on the upper side of the upper filter plate 51 .

[0045] Specifically, the first plug plate 111 and the second plug plate 112 are plugged into the inner sides of the two connecting grooves 113, so that when the upper filter plate 51 and the lower filter plate 53 need to be connected to the upper and lower sides of the connecting hollow block 52 respectively, the connection between the upper filter plate 51 and the lower filter plate 53 and the connecting hollow block 52 is also convenient enough;

[0046] In addition, the arrangement of the slide groove 131 and the slide plate 132 can further limit the movement of the second mounting plate 85, thereby increasing the stability of the second mounting plate 85 during movement;

[0047] In addition, the discharge pipe 71 can discharge the relatively clean muddy water after filtration, and the one-way valve 72 can control the discharge pipe 71. At the same time, the baffle 12 can limit the mud during filtration on the upper side of the upper filter plate 51, so that when the upper filter plate 51 moves back and forth and filters the mud, the mud is not easy to slide or shake off from the upper side of the upper filter plate 51.

[0048] The working principle of the waste sludge flocculation and sedimentation treatment device proposed in the embodiment of the present invention is as follows:

[0049] When the device is in use, the staff can prepare the mud and flocculant, and add them into the mixing box 1 through the feed pipe 32 and the feeding pipe 31 respectively, and then start the first servo motor 61 to drive one of the gears 63 to rotate, and through the two mutually meshing gears 63, drive the two rotating rods 64 to rotate in opposite directions, and then drive the first stirring plate 651 and the second stirring plate 652 to stir in opposite directions, so that the mud and flocculant are fully mixed in the mixing box 1. When the mud and flocculant are evenly mixed, start the water pump 34, and the water pump 34 will pump the stirred mud through the connecting pipe 33. The mud is extracted into the processing box 4. Inside the processing box 4, the second servo motor 82 is started to drive the turntable 83 to rotate. The rotation of the turntable 83 drives the second mounting plate 85 and the filter assembly 5 on the upper side of the second mounting plate 85 to perform eccentric reciprocating motion through the rotating connecting rod 88. The mud is double-filtered by the upper filter plate 51 and the lower filter plate 53 to remove the solidified mud blocks therein, and the relatively clean mud water will be collected on the inner side of the processing box 4. When the filtered mud water accumulates to a certain amount, the one-way valve 72 is opened, and the relatively clean mud water will be discharged from the inner side of the processing box 4 through the discharge pipe 71.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
