Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to a sedimentation device for wastewater treatment. Background Art

[0002] Wastewater often contains a large amount of suspended matter and colloidal substances, which not only affect the water quality, but may also cause blockage or wear to subsequent treatment equipment. At this time, through sedimentation treatment, gravity can be used to make these larger suspended matter and colloidal substances sink to the bottom of the pool, effectively removing them and improving the clarity of the wastewater;

[0003] In actual use, the existing sedimentation devices for wastewater treatment generally use flocculants to assist in causing tiny particles, suspended matter or organic matter in the wastewater to form larger flocs, which are easy to separate from the wastewater. However, the existing flocculants are generally sprinkled directly onto the surface of the wastewater manually and slowly mixed and reacted. Since the wastewater content inside the sedimentation tank is generally high, when the flocculant slowly mixes and reacts from the surface of the wastewater to the bottom of the wastewater cavity, the mixing reaction time is relatively long, and the mixing reaction degrees of the upper and lower parts of the wastewater in the sedimentation tank cavity with the flocculant are different, which will greatly reduce the effect of wastewater treatment. Summary of the invention

The present invention provides a sedimentation device for wastewater treatment, which effectively prevents the mixing reaction efficiency of flocculant raw materials and wastewater from being reduced by arranging a first stirring rod and a second stirring rod and other structures; avoids directly pouring flocculant raw materials from the wastewater surface and thereby reducing the mixing effect of flocculant and wastewater by arranging a rectangular shell and a movable block and other structures; and by placing the rectangular shell and the movable block in the middle area of ​​the wastewater and releasing the flocculant raw materials outward from the middle area of ​​the wastewater.

When the first stirring rod and the second stirring rod respectively drive the first block and the second block to rotate, so that the first block and the second block squeeze the movable block at the same time, the facing ends of the two movable blocks will move toward the central area of ​​the material placement chamber at the same time, so that the flocculant raw materials will be sprayed outward through the discharge port.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 10 As shown, the present invention provides a sedimentation device for wastewater treatment, including a sedimentation tank 1, and also including:

[0038] A driving module 2, which is arranged inside the sedimentation bin 1;

[0039] The resistance component 3 is installed on the driving module 2 in a circular manner with equal angles;

[0040] The movable component 4 is movably connected to the abutting component 3;

[0041] The driving module 2 includes a rotating shaft 22, a planetary gear module 23 is sleeved on the middle part of the rotating shaft 22, and an upper rotating plate 24 and a lower rotating plate 25 are respectively provided at the upper and lower ends of the rotating shaft 22; the upper rotating plate 24 includes a first stirring rod 241 and a first stop block 242 installed on the bottom surface of the first stirring rod 241, and the lower rotating plate 25 includes a second stirring rod 251 and a second stop block 252 installed on the top surface of the second stirring rod 251.

[0042] like Figures 2 to 4 As shown, the interference component 3 includes a rectangular shell 31, and both sides of the rectangular shell 31 are equipped with discharge ports 33 connected to the movable component 4;

[0043] The movable assembly 4 includes a movable block 41. The movable block 41 is provided with two groups, which are symmetrically arranged on the upper and lower sides of the inner cavity of the rectangular shell 31. The two sides of the upper movable block 41 are equipped with a material storage bin 45.

[0044] The driving module 2 includes a servo motor 21, which is fixedly connected to the top of the sedimentation bin 1, and the output end of the servo motor 21 is fixedly connected to the top of the rotating shaft 22;

[0045] The above scheme is adopted: when the servo motor 21 is running, it will drive the rotating shaft 22 so that the rotating shaft 22 drives the first stirring rod 241, the first stop block 242, the planetary gear module 23, the second stirring rod 251 and the second stop block 252 to rotate simultaneously, so as to stir the wastewater in the inner cavity of the sedimentation bin 1 when the flocculant is added, thereby improving the mixing effect of the wastewater and the flocculant.

[0046] like Figure 5 and Figures 7 to 10 As shown, the planetary gear module 23 includes a ring gear, a sun gear, and planetary gears. The ring gear is fixedly connected to the rectangular housing 31 , the sun gear is sleeved on the outer wall of the rotating shaft 22 , and the planetary gears are movably connected to the lower rotating plate 25 .

[0047] like Figures 7 to 10 As shown, the lower rotating plate 25 includes a connecting rod 253 movably engaged with the planetary gear, the bottom end of the first stop block 242 is in contact with the movable block 41 located on the upper side, and the top of the second stop block 252 is in contact with the movable block 41 located on the lower side.

[0048] The above scheme is adopted: through the design of the planetary gear module 23, the rotation of the rotating shaft 22 will drive the sun gear in the planetary gear module 23 to rotate in the same direction. At this time, when the sun gear located in the middle rotates, it will pass through the planetary gear and make the planetary gear drive the connecting rod 253 to rotate in the middle area between the ring gear and the sun gear. At this time, the connecting rod 253 is driven by the planetary gear and synchronously drives the second stirring rod 251 to rotate. Since the first stirring rod 241 is directly sleeved on the outer wall of the upper end of the rotating shaft 22, and the second stirring rod 251 is connected to the lower end of the inner cavity of the sedimentation bin 1 through the connecting rod 253, the first stirring rod 241 and the second stirring rod 251 will have different rotation directions, and the rotation speeds of the two are also different. The rotation directions of the first stirring rod 241 and the second stirring rod 251 are as follows: Figure 8 and Fig. 9 shown.

[0049] like Figure 5 As shown, a mounting block 32 is fixedly connected to the middle end of the side wall of the rectangular housing 31 away from the planetary gear module 23 , and the end of the mounting block 32 away from the rectangular housing 31 is fixedly connected to the inner wall of the sedimentation bin 1 .

[0050] The above solution is adopted: the rectangular shell 31 placed inside the sedimentation bin 1 is fixed by the mounting block 32 , thereby improving the overall stability of the rectangular shell 31 .

[0051] like Figure 4 and Figure 5 As shown, a one-way valve is installed on the outer side of the discharge port 33 away from the end of the rectangular shell 31 , and a material placement cavity 44 is formed between the two discharge ports 33 . The upper and lower sides of the inner cavity of the material placement cavity 44 are both sleeved with the movable block 41 .

[0052] like Figure 4 As shown, material storage bins 45 are installed on both sides of the upper end of the inner cavity of the rectangular shell 31. The top of the material storage bin 45 is fixedly connected to the inner wall of the rectangular shell 31. A leather plug 43 is movably sleeved on the top of the material storage bin 45. The bottom end of the leather plug 43 passes through the rectangular shell 31 and extends to the interior of the material storage bin 45. The movable block 41 is elastically connected to the movable block 41 through a flexible spring 42.

[0053] The above scheme is adopted: the leather plug 43 is pulled outward, and the flocculant raw material can be poured into the interior of the material storage bin 45, and the leather plug 43 is used to block the top of the material storage bin 45 to achieve the closure of the inner cavity of the opposite material storage bin 45. When the ends of the two movable blocks 41 located outside the rectangular shell 31 are abutted, the ends of the two movable blocks 41 located inside the rectangular shell 31 will move toward each other synchronously, and then the flocculant raw material in the opposite material cavity 44 will be sprayed out. When the upper movable block 41 moves upward to release the obstruction of the lower end of the opposite material storage bin 45, the flocculant raw material inside the material storage bin 45 is The flocculant raw material will be replenished into the interior of the feeding chamber 44. When only one movable block 41 is moved by resistance, the downward pressure of the single movable block 41 cannot ensure that the flocculant raw material inside the feeding chamber 44 is sprayed out. The movable block 41 and the discharge port 33 will replenish the flocculant raw material. When the outer side of the movable block 41 is not pressed, the flexible spring 42 will suddenly drive the movable block 41 to reset. Under the rapid action of the elastic force of the flexible spring 42, the bottom surface of the movable block 41 moves upward slightly, so that the flocculant raw material in the inner cavity of the feeding bin 45 can fall into the feeding chamber 44.

[0054] like Figure 4 As shown, both sides of the movable block 41 away from the end of one side of the rectangular shell 31 are provided with bevels, the outer side of the upper movable block 41 is in contact with the first stop block 242, and the outer side of the lower movable block 41 is in contact with the second stop block 252.

[0055] The above scheme is adopted: when the first stirring rod 241 drives the first block 242 and the second stirring rod 251 drives the second block 252 to rotate, the first block 242 will contact the outer bevel of the upper movable block 41, and continuously apply pressure to the upper movable block 41 through the bevel, forcing the first block 242 to squeeze the upper movable block 41 and move inside the rectangular shell 31. Similarly, the second block 252 will first contact the outer bevel of the lower movable block 41, and continuously apply pressure to the lower movable block 41 through the bevel, so that it moves inside the movable block 41. When the two movable blocks 41 move toward each other inside the rectangular shell 31 at the same time, the flocculant raw material inside the opposite material chamber 44 will be sprayed outward.

[0056] like Figure 2 As shown, a wastewater inlet 5 is installed on one side of the top of the sedimentation bin 1, and water outlets are installed on both sides of the lower end of the inner cavity of the sedimentation bin 1.

[0057] Adopting the above scheme: the upper end of the sedimentation bin 1 is spliced ​​and assembled with combined bolts. When the inside of the sedimentation bin 1 needs to be cleaned, it is only necessary to unscrew the bolts on the outer wall of the sedimentation bin 1 to complete the disassembly of the entire sedimentation bin 1.

[0058] like Figure 5 and Fig.10As shown, the ring gear of the planetary gear module 23 is fixedly connected to the rectangular housing 31 , and a circular groove is provided in the contact area between the bottom of the planetary gear module 23 and the connecting rod 253 .

[0059] With the above solution, the spacing of the circular grooves at the bottom of the planetary gear module 23 is small, which can only ensure that water can enter the interior of the planetary gear module 23, and floating objects remaining in the water cannot enter the inner cavity of the planetary gear module 23.

[0060] The working principle and use process of the present invention:

[0061] First, unscrew the bolts on the outer wall of the sedimentation bin 1 to expose the interior of the sedimentation bin 1 completely, pull up the leather plug 43 and the movable block 41, the leather plug 43 releases the seal of the opposite bin 45, the movable block 41 releases the seal of the communicating area between the opposite bin 45 and the discharge port 33, pour the flocculant raw material into the interior of the bin 45, the flocculant raw material will fall into the feeding cavity 44 through the discharge port 33 until it falls on the top surface of the lower movable block 41, at this time, the flocculant raw material placed in the feeding cavity 44 is half of the amount, and at the same time, release the pull on the movable block 41, and the movable block 41 is reset by the elastic force of the flexible spring 42. Figure 4 As shown, the bottom surface of the upper movable block 41 and the bottom surface of the discharge port at the bottom end of the material storage bin 45 are in the same horizontal plane;

[0062] Secondly, wastewater is poured into the sedimentation bin 1 through the wastewater inlet 5 until it is submerged above the first stirring rod 241. At this time, the resistance component 3 and the movable component 4 will be located in the center area of ​​the wastewater. The servo motor 21 is started, and the output end of the servo motor 21 drives the rotating shaft 22 to rotate. During the rotation of the rotating shaft 22, the first stirring rod 241 and the second stirring rod 251 will be driven to rotate in opposite directions through the planetary gear module 23, and the rotation speeds of the two will also be different.

[0063] Subsequently, when the first stirring rod 241 and the second stirring rod 251 respectively drive the first block 242 and the second block 252 to rotate, when the first block 242 and the second block 252 squeeze the movable block 41 at the same time, the ends of the two movable blocks 41 facing each other will move toward the central area of ​​the material chamber 44 at the same time, which will cause the flocculant raw material to be sprayed outward through the discharge port 33. Due to the design of the planetary gear module 23, the first block 242 and the second block 252 will correspond to each other in different areas, thereby achieving the purpose of synchronously squeezing the movable block 41 to realize the outward spraying of the flocculant raw material, that is, the flocculant will not be sprayed outward from only one rectangular shell 31.
