Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment device. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, and transportation.

[0003] In the sewage treatment process, workers transfer the sewage that has been filtered for large impurities into a flocculation tank, and add a flocculant to it, so as to react with the pollutants in the sewage and generate flocculants. To ensure the normal operation of the flocculation tank, it is necessary to periodically clean the flocculants accumulated in the tank. However, in most of the existing cleaning methods, it is necessary to stop the operation of the flocculation tank first to suspend the sewage transportation until the cleaning is completed and then the flocculation tank works again to treat and transport the sewage, which affects the sewage treatment efficiency.

[0004] Therefore, a sewage treatment device that can clean the flocculants without stopping working is proposed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0049] Please refer to Figure 1-8 , the present invention discloses a sewage treatment device, including a barrel body 1, which is provided with a positioning plate 11 at the top, and a liquid inlet 12 and a liquid outlet 13 are connected to the bottom. A filter screen 14 for filtering flocculants is provided at the liquid outlet 13;

[0050] A stirring component 2, rotatably arranged in the barrel body 1, is used for stirring the sewage and flocculant in the barrel body 1;

[0051] A switching component 3, arranged at the bottom of the positioning plate 11 and connected to one end of the stirring component 2;

[0052] A partition component 4, including a multi-stage telescopic part 41 vertically arranged in the barrel body 1, is used for partitioning the inner cavity of the barrel body 1;

[0053] A telescopic component 42, arranged between the switching component 3 and the multi-stage telescopic part 41, is used for driving the multi-stage telescopic part 41 to expand and contract;

[0054] A cleaning component 5, arranged in the barrel body 1, one end of which is detachably connected to the switching component 3, is used for cleaning the flocculants in the barrel and on the filter screen 14 and discharging them out of the barrel.

[0055] In the specific implementation, when sewage needs to be treated, the sewage and the flocculant enter the barrel body 1 through the corresponding liquid inlet 12. At the same time, the stirring component 2 stirs and mixes the sewage and the flocculant to promote the formation of flocs. When enough flocs are generated in the barrel body 1, the stirring component 2 drives the telescopic assembly 42 to work through the switching component 3, so that the multi-stage telescopic member 41 extends until the inner cavity of the barrel body 1 is divided into a stirring cavity located at the axis of the barrel body 1 and a cleaning cavity surrounding the stirring cavity. At this time, the stirring component 2 is located in the stirring cavity, and the cleaning component 5 is located in the cleaning cavity. Then, the stirring component 2 stops the movement of the multi-stage telescopic member 41 through the switching component 3. Subsequently, the liquid outlet 13 discharges the sewage in the cleaning cavity to the next process. At the same time, the filter screen 14 prevents the flocs from flowing out of the barrel body 1 together with the sewage. When the sewage in the cleaning cavity is discharged completely, the switching component 3 is connected to the cleaning component 5 and drives the cleaning component 5 to clean the flocs on the inner wall of the barrel body 1 and the filter screen 14 in the cleaning cavity through the rotation of the stirring component 2, so as to discharge them from the barrel body 1. After the cleaning is completed, the switching component 3 is separated from the cleaning component 5. At the same time, the multi-stage telescopic member 41 is driven to contract again through the rotation of the stirring component 2, and the flocs in the stirring cavity diffuse towards the barrel wall until waiting for the next cleaning of the cleaning component 5.

[0056] In the present invention, through the cooperation among the switching component 3, the partitioning component 4 and the cleaning component 5, when there are enough flocs in the barrel, the stirring assembly makes the multi-stage telescopic member 41 extend through the switching component 3 to divide the inner cavity of the barrel body 1 into a stirring cavity and a cleaning cavity. At this time, the sewage continues to be treated in the stirring cavity. Subsequently, the stirring assembly makes the cleaning component 5 clean the flocs in the cleaning cavity again through the switching component 3. After the cleaning is completed, the stirring assembly makes the multi-stage telescopic member 41 contract through the switching component 3, and the flocs diffuse towards the barrel wall until the next operation of the cleaning component 5. The whole process does not need to stop the work of the barrel body 1, and the sewage can be continuously treated, improving the treatment efficiency.

[0057] In one embodiment, a partitioning ring 15 is further provided at the bottom of the positioning barrel, and a slot 151 is opened at its bottom;

[0058] The multi-stage telescopic member 41 includes a positioning cover 411 vertically arranged at the bottom of the positioning plate 11. A moving cover 412 is vertically slidably arranged in the positioning cover 411, and its top is rotatably connected to the telescopic assembly 42;

[0059] A partitioning cover 413 corresponding to the partitioning ring 15 is further vertically slidably arranged in the moving cover 412. The top of the partitioning cover 413 is rotatably connected to the telescopic assembly 42. When the partitioning cover 413 is inserted into the slot 151, the chamber located in the partitioning cover 413 is the stirring cavity, and its outside is the cleaning cavity.

[0060] With such a design, when it is necessary to partition the inner cavity of the barrel body 1, the stirring member 2 rotates and causes the switching member 3 to drive the moving cover 412 and the partitioning cover 413 to move downward through the telescopic assembly 42 until the bottom of the partitioning cover 413 is inserted into the slot 151. At this time, the liquid in the positioning cover 411 is isolated from the liquid outside it, and the operation of the stirring member 2 will not affect the operation of the cleaning member 5. After the cleaning member 5 completes its work, the transmission member drives the moving cover 412 and the partitioning cover 413 to move upward again through the telescopic assembly 42 to reconnect the inner cavity of the barrel body 1.

[0061] In one embodiment, the stirring member 2 includes a stirring rod 21 vertically and rotatably arranged in the barrel body 1;

[0062] The switching member 3 includes an adjusting column 31 rotatably arranged at the bottom of the positioning plate 11 and connected to the stirring rod 21, and a bidirectional thread is provided on its surface;

[0063] The telescopic assembly 42 includes a first moving block 421 sleeved on the adjusting column 31 and threadedly connected thereto. The outer wall of the first moving block 421 is rotatably connected to the moving cover 412. A connecting sleeve 422 connected to the stirring rod 21 is rotatably arranged at the bottom of the first moving block 421, and a double-thread is provided on its surface. When the adjusting column 31 rotates, the first moving block 421 is used to drive the moving cover 412 and the connecting sleeve 422 to move vertically back and forth together;

[0064] It also includes a second moving block 423 coaxially sleeved on the connecting sleeve 422 and threadedly connected thereto. The outer wall of the second moving block 423 is rotatably connected to the partitioning cover 413 and is used to drive the partitioning cover 413 to move vertically back and forth;

[0065] A first limiting rod 424 is vertically arranged at the bottom of the positioning plate 11. The first limiting rod 424 sequentially passes through the first moving block 421 and the second moving block 423 and is vertically slidably connected thereto, so as to prevent the first moving block 421 and the second moving block 423 from rotating with the corresponding components when the adjusting column 31 and the connecting sleeve 422 rotate.

[0066] With such a design, when it is necessary to extend the multi-stage telescopic member 41, the stirring rod 21 drives the adjusting column 31 and the connecting sleeve 422 to rotate. While the first limiting rod 424 prevents the first moving block 421 from rotating with the adjusting column 31, it causes the moving cover 412 and the connecting sleeve 422 to move downward together. At the same time, the first limiting rod 424 also prevents the second moving block 423 from rotating with the connecting sleeve 422 and causes it to drive the partition cover 413 to move further downward until the partition cover 413 is inserted into the slot 151. At this time, both the first moving block 421 and the second moving block 423 are located at the bottom end of the corresponding double-thread. When it is necessary to contract the multi-stage telescopic member 41, the stirring rod 21 drives the adjusting column 31 and the connecting sleeve 422 to rotate again, and the first moving block 421 and the second moving block 423 slide upward along the corresponding threads to drive the moving cover 412 and the partition cover 413 to move upward respectively.

[0067] In one embodiment, the switching component 3 further includes a first inner ratchet wheel 32 coaxially fixed inside the adjusting column 31;

[0068] A plurality of first ratchet teeth 33 that are circumferentially distributed and meshed with the first inner ratchet wheel 32 in a one-way manner are provided on the section of the stirring rod 21 extending into the adjusting column 31. When the first ratchet teeth 33 are meshed with the first inner ratchet wheel 32, the stirring rod 21 is used to drive the adjusting column 31 to rotate together;

[0069] A second inner ratchet wheel 34 is also coaxially fixed in the connecting sleeve 422. A plurality of second ratchet teeth 35 that are circumferentially distributed and meshed with the second inner ratchet wheel 34 in a one-way manner are also provided on the stirring rod 21. The first inner ratchet wheel 32 and the second inner ratchet wheel 34 have the same rotation direction;

[0070] A connecting component 36 connected to the stirring rod 21 is also rotatably provided at the top of the positioning plate 11, and one end of it is detachably connected to the cleaning component 5. When the connecting component 36 is connected to the cleaning component 5, it is used to drive the cleaning component 5 to clean the impurities in the barrel.

[0071] With such a design, when it is necessary to mix the sewage and the flocculant, the stirring rod 21 drives the connecting component 36 to rotate and stirs the sewage and the flocculant. At this time, each ratchet tooth is not meshed with the corresponding inner ratchet wheel. When it is necessary to partition the inner cavity of the barrel body 1, the stirring rod 21 drives the connecting component 36 to rotate in the reverse direction. At this time, the first ratchet teeth 33 are meshed with the first inner ratchet wheel 32 and drive the adjusting column 31 to rotate, so that the first moving block 421 drives the moving cover 412 and the connecting sleeve 422 to move downward. At the same time, the second ratchet teeth 35 are meshed with the second inner ratchet wheel 34 and drive the connecting sleeve 422 to rotate, so that the second moving block 423 drives the partition cover 413 to move downward until both the first moving block 421 and the second moving block 423 are located at the bottom end of the corresponding double-thread.

[0072] In one embodiment, the connection component 36 includes a turntable 361 rotatably arranged on the positioning plate 11 and connected to the top of the stirring rod 21. Two guide grooves 3611 are symmetrically arranged on the top of the turntable 361 in a mirror image manner.

[0073] Two adjusting blocks 362 are slidably inserted into the corresponding guide grooves 3611 on the turntable 361. Meshing teeth 363 are evenly distributed on the outer sides of the adjusting blocks 362. The meshing teeth 363 are detachably meshed with one end of the cleaning component 5. A first power unit 364 connected to the two adjusting blocks 362 is further arranged on the top of the positioning plate 11, and is used to drive each adjusting block 362 to move towards or away from the axis of the positioning plate 11.

[0074] With such a design, when mixing the sewage and the flocculant, the stirring rod 21 drives the turntable 361 to rotate together. At this time, the meshing teeth 363 on each adjusting block 362 are not meshed with the gear 52, avoiding accidental operation of the cleaning component 5. When it is necessary to clean the flocs, the first power unit 364 drives each adjusting block 362 to move away from the axis of the positioning plate 11. At this time, the meshing teeth 363 on each adjusting block 362 extend out of the turntable 361 and are meshed with one end of the cleaning component 5, thereby driving the cleaning component 5 to work.

[0075] Preferably, the first power unit 364 can adopt a double-axis two-way cylinder in the prior art.

[0076] In one embodiment, the cleaning component 5 includes two first transmission rods 51 vertically and rotatably arranged in the barrel 1. A double-thread is arranged on the surface of the first transmission rods 51. The top of the first transmission rods 51 passes through the positioning plate 11 and is provided with gears 52. When each adjusting block 362 extends out of the turntable 361, each gear 52 is meshed with the meshing teeth 363 on the corresponding adjusting block 362.

[0077] Third sliding blocks 53 are also arranged on each first transmission rod 51 in a threaded manner. An annular filter ring 54 is further arranged in the barrel 1. The filter ring 54 is sleeved on the outer periphery of each first transmission rod 51 and is connected to each third sliding block 53. When each first transmission rod 51 rotates, each third sliding block 53 drives the filter ring 54 to move up and down reciprocally, and its cleaning surfaces are respectively in contact with the inner wall of the barrel 1 and the filter screen 14.

[0078] Two second limiting rods 55 are vertically arranged in the barrel 1. Each second limiting rod 55 is located on one side of the corresponding third sliding block 53 and is vertically slidably connected to the third sliding block 53, and is used to restrict the rotation of the corresponding third sliding block 53.

[0079] With such a design, when it is necessary to clean the flocculants, the liquid outlet 13 is opened to allow the sewage in the cleaning chamber to flow to the next process. During the flow of the sewage, the filter ring 54 and the filter screen 14 intercept the flocculants in the sewage, preventing the flocculants from flowing out of the barrel body 1 along with the sewage. After the sewage in the cleaning chamber is discharged, the first power unit 364 drives each adjusting block 362 to extend and protrude from the turntable 361. As the turntable 361 continues to rotate, each first transmission rod 51 is driven to rotate by the engagement of each gear 52 with the corresponding meshing tooth 363. At this time, each second limiting rod 55 prevents the corresponding third adjusting block 362 from rotating with the first transmission rod 51 while driving the filter ring 54 to move upward. During the movement, the filter ring 54 scrapes off the flocculants attached to the inner wall of the filter screen 14 and the barrel body 1.

[0080] In one embodiment, an outlet 16 is opened at the top of the barrel body 1, and the outlet 16 is located below the positioning plate 11. A storage box 6 for storing flocculants is also sleeved on the outer wall of the barrel body 1, and its feed inlet is communicated with the outlet 16;

[0081] The cleaning component 5 further includes a plurality of scraping plates 56 rotatably arranged at the bottom of the positioning plate 11 and on one side of the outlet 16. The scraping surface of the scraping plate 56 corresponds to the cleaning surface of the filter ring 54, and is used for scraping off the flocculants attached to the filter ring 54 and transferring them into the storage box 6. A torsion spring (not shown in the figure) is also provided at the rotation connection of the scraping plate 56, which is used to apply a downward rotation torque to the scraping plate 56.

[0082] With such a design, when the filter ring 54 moves upward until it contacts each scraping plate 56, as the filter ring 54 continues to move upward and applies an upward rotation thrust to each scraping plate 56, at this time each torsion spring is compressed and the scraping surface of the corresponding scraping plate 56 always contacts the cleaning surface of the filter ring 54, so as to scrape off the flocculants attached to the filter ring 54 until they fall into the storage box 6.

[0083] In one embodiment, the stirring rod 21 includes a transmission section 211 vertically and rotatably arranged in the barrel body 1. Its top sequentially penetrates through the adjusting column 31 and the positioning plate 11 coaxially and is connected to the turntable 361. The above-mentioned first ratchet tooth 33 and second ratchet tooth 35 are both arranged on the transmission section 211;

[0084] A plurality of stirring sections 212 are also circumferentially distributed on the transmission section 211. Each stirring section 212 is a multi-stage telescopic rod, which is used for stirring the sewage and the flocculant;

[0085] The stirring component 2 further includes a second power unit 22 arranged at the bottom of the barrel body 1. Its moving end extends into the barrel body 1 and is connected to the transmission section 211, and the connection between the second power unit 22 and the barrel body 1 is a dynamic seal connection, which is used to drive the stirring rod 21 to rotate.

[0086] With such a design, when it is necessary to mix the sewage and the flocculant, the second power unit 22 drives each stirring section 212 to rotate around the axis of the transmission section 211 through the transmission section 211, so that each stirring section 212 agitates the sewage and the flocculant. At the same time, the transmission section 211 drives the turntable 361 to rotate and makes each ratchet tooth not engage with the corresponding internal ratchet wheel. When it is necessary to partition the inner cavity of the barrel body 1, the second power unit 22 drives the transmission section 211 to reverse so that each ratchet tooth engages with the corresponding internal ratchet wheel. At this time, the switching member 3 drives the multi-stage telescopic member 41 to extend downward. During the downward movement of the partition cover 413, it contacts each stirring end and applies a downward pressure thereto. Each stirring section 212 is compressed and contracted until the partition cover 413 is inserted into the slot 151, so as to continue to agitate the sewage and the flocculant in the partition cover 413 without affecting the operation of the partition cover 413.

[0087] Preferably, the second power unit 22 can adopt a motor in the prior art.

[0088] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0089] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0090] In addition, "a plurality of" means more than two.

[0091] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
