Specific implementation plan

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0032] See also Figure 1-Figure 5 .

[0033] The utility model discloses a flocculation tank decontamination device, comprising:

[0034] Flocculation tank 1;

[0035] The stirring component 2 is arranged in the flocculation barrel 1 and is used to stir the sewage and the flocculant in the flocculation barrel 1 so that the sewage and the flocculant are fully mixed;

[0036] A scraper 3, which is annular and disposed at the bottom of the flocculation barrel 1, and the scraper 3 abuts against the inner wall of the flocculation barrel 1, and is used to scrape off dirt attached to the inner wall of the flocculation barrel 1;

[0037] The transmission component 4 is arranged in the flocculation barrel 1, and is used for driving the scraper 3 to move vertically back and forth when the stirring component 2 is working.

[0038] In the specific implementation, the staff pours the sewage and flocculant after preliminary filtration into the flocculation barrel 1, and starts the stirring component 2. The stirring component 2 fully mixes the sewage and flocculant in the flocculation barrel 1 and produces floccules. When the stirring component 2 is working, the scraper 3 is driven to move vertically back and forth through the transmission component 4 to scrape off the dirt attached to the inner wall of the flocculation barrel 1, thereby completing the cleaning of the dirt on the inner wall of the flocculation barrel 1.

[0039] In the utility model, the stirring component 2 drives the scraper 3 to scrape off the flocculation attached to the inner wall of the flocculation barrel 1 through the transmission component 4, so that the flocculation barrel 1 automatically cleans the dirt attached to the inner wall of the flocculation barrel 1 during operation, without manual cleaning, thereby improving work efficiency.

[0040] In one embodiment, the transmission component 4 includes a reciprocating screw 41 vertically rotatably disposed in the flocculation barrel 1, and the scraper 3 is disposed at one end of the reciprocating screw 41 close to the bottom of the flocculation barrel 1. When the reciprocating screw 41 rotates, the scraper 3 is driven to reciprocate up and down in the flocculation barrel 1;

[0041] The transmission component 4 also includes a linkage assembly, which is used to drive the reciprocating screw 41 to rotate when the stirring component 2 is working.

[0042] With such a design, the use of the reciprocating screw 41 allows the stirring component 2 to rotate in one direction continuously without controlling the rotation direction of the stirring component 2 .

[0043] In one embodiment, the linkage assembly includes a ring gear 21 arranged on the stirring component 2 and a gear 42 arranged at one end of the reciprocating screw 41. The ring gear 21 is meshed with the gear 42. The stirring component 2 stirs in a rotational manner and drives the ring gear 21 to rotate, thereby driving the reciprocating screw 41 to rotate, thereby realizing the scraper 3 to move back and forth up and down in the flocculation barrel 1.

[0044] In one embodiment, a storage box 6 is sleeved on the top of the outer wall of the flocculation barrel 1. The storage box 6 is annular and communicates with the top of the flocculation barrel 1 to store the flocculated materials scraped by the scraper 3.

[0045] The cross-section of the scraper 3 is "L"-shaped. The scraper 3 includes a connecting plate 31 threadedly connected to the reciprocating screw 41 and a scraping plate 32 abutting against the inner wall of the flocculation barrel 1. When the reciprocating screw 41 rotates, the connecting plate 31 drives the scraping plate 32 to move, and the scraping plate 32 scrapes the dirt on the inner wall of the flocculation barrel 1. After the scraper 3 rises to the top of the flocculation barrel 1, the dirt automatically flows into the storage box 6.

[0046] This design can achieve centralized collection of waste and facilitate subsequent centralized treatment.

[0047] In one embodiment, the annular scraper 3 is composed of a plurality of arc segments, and a plurality of reciprocating screws 41 are provided, which are respectively connected to each arc segment to drive each arc segment to reciprocate up and down;

[0048] The connecting plate 31 and the scraping plate 32 in the arc segment are rotatably connected via a rotating joint 33, and a torsion spring (not shown in the figure) is provided on the rotating joint 33 to drive the scraping plate 32 to rotate toward the bottom of the flocculation barrel 1, and the length of the scraping plate 32 is greater than the gap between the connecting plate 31 and the inner wall of the flocculation barrel 1. With this design, after the scraping plate 3 rises to the top of the flocculation barrel 1, driven by the torsion spring, the scraping plate 32 rotates toward the bottom of the flocculation barrel 1, which can better guide the dirt into the storage box 6.

[0049] In one embodiment, a receiving groove 321 is provided on the connecting plate 31, and the receiving groove 321 penetrates the top of the connecting plate 31 and one side of the inner wall of the flocculation barrel 1 corresponding to the connecting plate 31, and is used to receive dirt. With such a design, when the scraping plate 32 rotates to one side to guide the dirt into the receiving box 6, a gap will be generated between two adjacent scraping plates 32, and the dirt will fall back into the flocculation barrel 1 from the gap between the two adjacent scraping plates 32. Therefore, the provision of the receiving groove 321 can effectively reduce the dirt from falling back into the flocculation barrel 1 from the gap.

[0050] In one embodiment, it also includes a limit block 34 arranged on a side of the connecting plate 31 close to the inner wall of the flocculation barrel 1. When the scraper plate 32 rotates upward, the scraper plate 32 abuts against the limit block 34. The limit block 34 is used to limit the rotation angle between the scraper plate 32 and the connecting plate 31 to avoid a gap between the scraper plate 32 and the inner wall of the flocculation barrel 1.

[0051] With this design, when the scraper 3 works in the flocculation barrel 1, the scraper plate 32 rotates upward and abuts against the limit block 34. The torsion spring accumulates force at this time, and the torsion spring always provides pressure on the scraper plate 32 against the inner wall of the flocculation barrel 1. When the reciprocating screw 41 rotates, the scraper plate 32 abuts against the inner wall of the flocculation barrel 1 and limits the rotation of the scraper plate 32, thereby preventing the reciprocating screw 41 from driving the scraper 3 to rotate during operation. When the scraper 3 rises to the top of the flocculation barrel 1, the torsion spring loses its constraint and drives the scraper plate 32 to rotate downward. At this time, the scraper plate 32 dumps the flocculate in the groove into the storage box 6. When the reciprocating screw 41 drives the scraper 3 to move downward, because the length of the scraper plate 32 is longer than the gap between the connecting plate 31 and the inner wall of the flocculation barrel 1, the scraper plate 32 again abuts against the inner wall of the flocculation barrel 1 and rotates upward during the descent. At this time, the torsion spring is tightened again to complete the reset.

[0052] In one embodiment, the gear ring 21 is divided into a toothed portion and a toothless portion, and the toothless portion is provided with a plurality of notches 211, an arcuate bar 22 is slidably provided in each notch 211, and teeth are provided on a side of the arcuate bar 22 away from the center of the flocculation barrel 1, and an adjusting component 5 is provided on a side of each arcuate bar 22 close to the center of the flocculation barrel 1 for adjusting the arcuate bar 22 to move toward and away from the inner wall of the flocculation barrel 1.

[0053] With such a design, when the scraper 3 is working, the gear 42 on each transmission component 4 meshes with the toothed portion on the gear ring 21, thereby increasing the transmission ratio between the gear 42 and the gear ring 21 (i.e., reducing the rotation speed of the gear 42 and reducing the movement speed of the scraper 3). When it is necessary to speed up the movement speed of the scraper 3, the staff can extend the corresponding arc bar 22 through the corresponding adjustment component 5 to make the teeth on the arc bar 22 mesh with the gear 42, thereby increasing the number of teeth on the surface of the gear ring 21 and reducing the transmission ratio between each gear 42 and the gear ring 21.

[0054] In one embodiment, the adjusting component 5 includes an adjusting plate 51 arranged at one end of the corresponding slot 211 close to the center of the flocculation barrel 1, a screw 52 is rotatably penetrated on the adjusting plate 51, and one end of the screw 52 close to the tooth surface of the gear ring 21 is rotatably connected to the corresponding arc strip 22, so as to adjust the corresponding arc strip 22 to slide in the corresponding slot 211.

[0055] With this design, when the number of teeth on the gear ring 21 needs to be increased, the staff rotates the screw 52 so that the screw 52 drives the corresponding adjustment plate 51 to move away from the center of the flocculation barrel 1 until the tooth surface of the adjustment plate 51 and the tooth surface of the gear ring 21 are on the same arc surface. When the number of teeth on the gear ring 21 needs to be reduced, the screw 52 is reversed to move the adjustment plate 51 toward the center of the flocculation barrel 1. At this time, the teeth on the adjustment plate 51 are not engaged with the gear 42.

[0056] In one embodiment, the stirring component 2 includes a power unit 23 disposed at the bottom of the flocculation barrel 1, and also includes a stirring rod 24 rotatably disposed in the flocculation barrel 1, the stirring rod 24 is "Y"-shaped and penetrates the bottom of the flocculation barrel 1 and is connected to the power unit 23, the gear ring 21 is disposed on the top of the stirring rod 24, and the stirring rod 24 is dynamically sealed with the bottom of the flocculation barrel 1, for stirring the sewage and flocculant in the flocculation barrel 1. The power unit 23 is a motor.

[0057] With this design, the power unit 23 drives the stirring rod 24 to rotate in the flocculation barrel 1, so that the sewage and flocculant in the flocculation barrel 1 are fully mixed, the output efficiency of the floccules is accelerated, and the centrifugal force generated by the stirring rod 24 when rotating in the sewage causes the floccules to adhere to the inner wall of the flocculation barrel 1, which is convenient for the scraper 3 to scrape them off.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
