DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] Please refer to Figures 1-8 The present application discloses a sewage treatment device, which comprises a barrel 1, the top of which is provided with a positioning plate 11, and the bottom of which is connected with a liquid inlet 12 and a liquid outlet 13, and the liquid outlet 13 is provided with a filter screen 14 for filtering flocculation;

[0050] A stirring component 2 is rotationally arranged in the barrel 1, for stirring sewage and flocculants in the barrel 1.

[0051] A switching component 3 is arranged at the bottom of the positioning plate 11 and connected with one end of the stirring component 2.

[0052] A separation component 4 comprises a multi-stage telescopic part 41 arranged vertically in the barrel 1, for separating the inner cavity of the barrel 1.

[0053] A telescopic assembly 42 is arranged between the switching component 3 and the multi-stage telescopic part 41, for driving the multi-stage telescopic part 41 to extend and retract.

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

[0055] In the embodiment, when sewage needs to be treated, the sewage and flocculants enter the barrel 1 through the corresponding liquid inlet 12, and the stirring component 2 stirs and mixes the sewage and flocculants to promote the generation of flocculants. When enough flocculants are generated in the barrel 1, the stirring component 2 drives the telescopic assembly 42 to work through the switching component 3, so that the multi-stage telescopic part 41 is extended until the inner cavity of the barrel 1 is divided into a stirring cavity located at the axis of the barrel 1 and a cleaning cavity located around 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 drives the multi-stage telescopic part 41 to stop moving through the switching component 3. Then, the sewage in the cleaning cavity is discharged to the next process through the liquid outlet 13, and the filter screen 14 prevents the flocculants from flowing out of the barrel 1 with the sewage. When the sewage in the cleaning cavity is discharged, the switching component 3 is connected with the cleaning component 5 and drives the cleaning component 5 to clean the inner wall of the barrel 1 and the flocculants on the filter screen 14 through the rotation of the stirring component 2, so as to discharge the flocculants out of the barrel 1. After cleaning, the switching component 3 is separated from the cleaning component 5, and the multi-stage telescopic part 41 is retracted through the rotation of the stirring component 2. The flocculants in the stirring cavity diffuse towards the barrel wall until the next cleaning of the cleaning component 5.

[0056] In the embodiment, when sewage needs to be treated, the sewage and flocculants enter the barrel 1 through the corresponding liquid inlet 12, and the stirring component 2 stirs and mixes the sewage and flocculants to promote the generation of flocculants. When enough flocculants are generated in the barrel 1, the stirring component 2 drives the telescopic assembly 42 to work through the switching component 3, so that the multi-stage telescopic part 41 is extended until the inner cavity of the barrel 1 is divided into a stirring cavity located at the axis of the barrel 1 and a cleaning cavity located around 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 drives the multi-stage telescopic part 41 to stop moving through the switching component 3. Then, the sewage in the cleaning cavity is discharged to the next process through the liquid outlet 13, and the filter screen 14 prevents the flocculants from flowing out of the barrel 1 with the sewage. When the sewage in the cleaning cavity is discharged, the switching component 3 is connected with the cleaning component 5 and drives the cleaning component 5 to clean the inner wall of the barrel 1 and the flocculants on the filter screen 14 through the rotation of the stirring component 2, so as to discharge the flocculants out of the barrel 1. After cleaning, the switching component 3 is separated from the cleaning component 5, and the multi-stage telescopic part 41 is retracted through the rotation of the stirring component 2. The flocculants in the stirring cavity diffuse towards the barrel wall until the next cleaning of the cleaning component 5.

[0057] In an embodiment, the positioning barrel bottom is further provided with a separation ring 15, and the bottom of the separation ring 15 is provided with a slot 151;

[0058] The multi-stage telescopic part 41 comprises a positioning cover 411 vertically arranged at the bottom of the positioning plate 11, and a moving cover 412 vertically slidably arranged in the positioning cover 411, and the top of the moving cover 412 is rotationally connected with the telescopic assembly 42;

[0059] The moving cover 412 is further vertically slidably provided with a separation cover 413 corresponding to the separation ring 15, and the top of the separation cover 413 is rotationally connected with the telescopic assembly 42. When the separation cover 413 is inserted into the slot 151, the cavity in the separation cover 413 is the stirring cavity, and the outside is the cleaning cavity.

[0060] When the inner cavity of the barrel 1 needs to be separated, the stirring part 2 rotates and drives the switching part 3 to move the movable cover 412 and the separation cover 413 downward through the telescopic assembly 42 until the bottom of the separation cover 413 is inserted into the insertion slot 151, at this time, the liquid in the positioning cover 411 is isolated from the liquid outside, and the work of the stirring part 2 will not affect the work of the cleaning part 5, when the cleaning part 5 completes the work, the transmission part drives the movable cover 412 and the separation cover 413 to move upward through the telescopic assembly 42, so that the inner cavity of the barrel 1 is connected again.

[0061] In an embodiment, the stirring part 2 comprises a stirring rod 21 vertically arranged in the barrel 1;

[0062] The switching part 3 comprises an adjusting column 31 arranged at the bottom of the positioning plate 11 and connected with the stirring rod 21, and a double-threaded hole is formed in the surface of the adjusting column 31;

[0063] The telescopic assembly 42 comprises a first moving block 421 sleeved on the adjusting column 31 and threadedly connected with the adjusting column 31, and the outer wall of the first moving block 421 is rotatably connected with the movable cover 412, a connecting sleeve 422 connected with the stirring rod 21 is arranged at the bottom of the first moving block 421, and a double-threaded hole is formed in the surface of the first moving block 421, when the adjusting column 31 rotates, the first moving block 421 is used for driving the movable cover 412 and the connecting sleeve 422 to vertically reciprocate together;

[0064] Further comprising a second moving block 423 coaxially sleeved on the connecting sleeve 422 and threadedly connected with the connecting sleeve 422, and the outer wall of the second moving block 423 is rotatably connected with the separation cover 413, and the second moving block 423 is used for driving the separation cover 413 to vertically reciprocate;

[0065] A first limiting rod 424 is vertically arranged at the bottom of the positioning plate 11, the first limiting rod 424 is sequentially inserted through the first moving block 421 and the second moving block 423 and is vertically slidably connected with the first moving block 421 and the second moving block 423, so that when the adjusting column 31 and the connecting sleeve 422 rotate, the first moving block 421 and the second moving block 423 do not rotate with the corresponding parts.

[0066] Thus, when the multi-stage telescopic member 41 needs to be extended, the stirring rod 21 drives the adjusting column 31 and the connecting sleeve 422 to rotate, the first limiting rod 424 prevents the first moving block 421 from rotating with the adjusting column 31 and drives the moving cover 412 and the connecting sleeve 422 to move downward together, and the first limiting rod 424 also prevents the second moving block 423 from rotating with the connecting sleeve 422 and drives the separating cover 413 to further move downward, until the separating cover 413 is inserted into the insertion slot 151, at this time, the first moving block 421 and the second moving block 423 are located at the bottom end of the corresponding double-threaded screw, when the multi-stage telescopic member 41 needs to be retracted, the stirring rod 21 drives the adjusting column 31 and the connecting sleeve 422 to rotate again, the first moving block 421 and the second moving block 423 slide upward along the corresponding screw to drive the moving cover 412 and the separating cover 413 to move upward, respectively.

[0067] In an embodiment, the switching component 3 further comprises a first internal ratchet wheel 32 coaxially fixed in the adjusting column 31;

[0068] The stirring rod 21 extends into the adjusting column 31 and is circumferentially uniformly distributed with a plurality of first ratchet teeth 33 that are unidirectionally engaged with the first internal ratchet wheel 32, when the first ratchet teeth 33 are engaged with the first internal ratchet wheel 32, the stirring rod 21 is used to drive the adjusting column 31 to rotate together;

[0069] The connecting sleeve 422 is also coaxially fixed with a second internal ratchet wheel 34, and the stirring rod 21 is also circumferentially uniformly distributed with a plurality of second ratchet teeth 35 that are unidirectionally engaged with the second internal ratchet wheel 34, the first internal ratchet wheel 32 and the second internal ratchet wheel 34 have the same rotation direction;

[0070] The top of the positioning plate 11 is also rotationally provided with a connecting assembly 36 connected with the stirring rod 21, and one end thereof is detachably connected with the cleaning component 5, when the connecting assembly 36 is connected with the cleaning component 5, it is used to drive the cleaning component 5 to clean the impurities in the barrel.

[0071] Thus, when the sewage and the flocculating agent need to be mixed, the stirring rod 21 drives the connecting assembly 36 to rotate and agitates the sewage and the flocculating agent, at this time, the ratchet teeth are not engaged with the corresponding internal ratchet wheel, when the inner cavity of the barrel 1 needs to be separated, the stirring rod 21 drives the connecting assembly 36 to reverse, at this time, the first ratchet teeth 33 are engaged with the first internal 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, and the second ratchet teeth 35 are engaged with the second internal ratchet wheel 34 and drive the connecting sleeve 422 to rotate, so that the second moving block 423 drives the separating cover 413 to move downward, until the first moving block 421 and the second moving block 423 are located at the bottom end of the corresponding double-threaded screw.

[0072] In an embodiment, the connecting assembly 36 comprises a rotating disc 361 rotatably arranged on the positioning plate 11 and connected with the top of the stirring rod 21, and two guide grooves 3611 are symmetrically formed on the top of the rotating disc 361;

[0073] Two adjusting blocks 362 are further arranged on the rotating disc 361 and slidably arranged in the corresponding guide grooves 3611, and the outer side of each adjusting block 362 is uniformly provided with engaging teeth 363; the engaging teeth 363 are detachably engaged with one end of the cleaning component 5; and the top of the positioning plate 11 is further provided with a first power unit 364 connected with the two adjusting blocks 362, for driving each adjusting block 362 to move towards or away from the axial center of the positioning plate 11.

[0074] In this way, when the sewage is mixed with the flocculating agent, the stirring rod 21 drives the rotating disc 361 to rotate, at this time, the engaging teeth 363 on each adjusting block 362 are not engaged with the gear 52, avoiding the accidental work of the cleaning component 5; when it is needed to clean the flocculating agent, the first power unit 364 drives each adjusting block 362 to move away from the axial center of the positioning plate 11, at this time, the engaging teeth 363 on each adjusting block 362 extend out of the rotating disc 361 and are engaged 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-shaft bidirectional air cylinder in the prior art.

[0076] In an embodiment, the cleaning component 5 comprises two first transmission rods 51 vertically rotatably arranged in the barrel 1, the surface of each first transmission rod 51 is provided with a bidirectional screw thread, the top of each first transmission rod 51 penetrates out of the positioning plate 11 and is provided with a gear 52, when each adjusting block 362 extends out of the rotating disc 361, each gear 52 is engaged with the engaging teeth 363 on the corresponding adjusting block 362;

[0077] A third sliding block 53 is further threadedly arranged on each first transmission rod 51; and the barrel 1 is further provided with a filter ring 54 in the form of a ring, the filter ring 54 is sleeved on the outer periphery of each first transmission rod 51 and is connected with each third sliding block 53, when each first transmission rod 51 rotates, each third sliding block 53 drives the filter ring 54 to reciprocate up and down, and the cleaning surface of the filter ring 54 is respectively in contact with the inner wall of the barrel 1 and the filter screen 14;

[0078] Two second limiting rods 55 are further vertically arranged in the barrel 1, each second limiting rod 55 is located on the side of the corresponding third sliding block 53 and is vertically and slidably connected with the third sliding block 53, for restricting the rotation of the corresponding third sliding block 53.

[0079] Thus, when the floc needs to be cleaned, the outlet 13 is opened to allow the sewage in the cleaning cavity to flow to the next process. During the sewage flow, the filter ring 54 and the filter screen 14 intercept the floc in the sewage to prevent the floc from flowing out of the barrel 1 with the sewage. When the sewage in the cleaning cavity is completely discharged, the first power unit 364 drives each adjusting block 362 to extend and extend the rotating disc 361. With the continuous rotation of the rotating disc 361, each first transmission rod 51 is driven to rotate through the meshing of each gear 52 and 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 floc attached to the filter screen 14 and the inner wall of the barrel 1.

[0080] In an embodiment, an outlet 16 is formed at the top of the barrel 1, and the outlet 16 is located below the positioning plate 11. The outer wall of the barrel 1 is further sleeved with a storage tank 6 for storing floc, and the inlet of the storage tank 6 is communicated with the outlet 16.

[0081] The cleaning component 5 further comprises a plurality of scraper plates 56 rotatably arranged at the bottom of the positioning plate 11 and located on one side of the outlet 16. The scraping surface of the scraper plate 56 corresponds to the cleaning surface of the filter ring 54, which is used to scrape off the floc attached to the filter ring 54 and transfer it into the storage tank 6. The rotating connection of the scraper plate 56 is further provided with a torsional spring (not shown in the figure), which is used to apply a downward torsional force to the scraper plate 56.

[0082] Thus, when the filter ring 54 moves upward until it contacts each scraper plate 56, the filter ring 54 continues to move upward and applies an upward rotating force to each scraper plate 56. At this time, each torsional spring is compressed and makes the scraping surface of the corresponding scraper plate 56 always in contact with the cleaning surface of the filter ring 54, thereby scraping off the floc attached to the filter ring 54 until it falls into the storage tank 6.

[0083] In an embodiment, the stirring rod 21 comprises a transmission segment 211 rotatably arranged in the barrel 1. The top of the transmission segment 211 is coaxially penetrated into the adjusting column 31 and the positioning plate 11 in sequence and is connected with the rotating disc 361. The first ratchet teeth 33 and the second ratchet teeth 35 are both arranged on the transmission segment 211.

[0084] The transmission segment 211 is further circumferentially distributed with a plurality of stirring segments 212. Each stirring segment 212 is a multi-stage telescopic rod, which is used to stir the sewage and the flocculant.

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

[0086] In this way, when the mixed sewage and flocculant need to be stirred, the second power unit 22 drives each stirring section 212 to rotate around the axis of the transmission section 211, so that each stirring section 212 stirs the sewage and flocculant, and the transmission section 211 drives the rotating disc 361 to rotate and makes each ratchet not mesh with the corresponding internal ratchet. When the inner cavity of the barrel 1 needs to be separated, the second power unit 22 reversely drives the transmission section 211 to make each ratchet mesh with the corresponding internal ratchet. At this time, the switching part 3 drives the multi-stage telescopic part 41 to extend downward, and the separation cover 413 contacts each stirring end and exerts downward pressure on it during the descending process. Each stirring section 212 is pressed to shrink until the separation cover 413 is inserted into the insertion slot 151, so that the sewage and flocculant in the separation cover 413 can be continuously stirred without affecting the work of the separation cover 413.

[0087] Preferably, the second power unit 22 can adopt an existing motor.

[0088] It should be noted that if the embodiment of the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, motion condition, etc. between the components in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications also change accordingly.
