The top end of the stirring shaft extends outside the sedimentation tank and is rotatably connected to the sedimentation tank. The driving motor is fixedly installed on the top of the sedimentation tank, and the output shaft of the driving motor is fixedly connected to the top end of the stirring shaft. The sedimentation plate is arranged on the inner wall of the bottom of the sedimentation tank, and the closing plate is arranged on one side of the sedimentation tank.

Detailed implementation manners

[0044] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1: Please refer to Figures 1 - 12 As shown, the present invention provides a technical solution: a self-cleaning sewage treatment sedimentation device, including a sedimentation device body 1, a water pump 2 is fixedly connected to the upper end of the sedimentation device body 1, and a filter grille 3 is fixedly connected to the sedimentation device body 1 on the side of the water pump 2.

[0046] With the setting of the filter grille 3 in this technical solution, during use, first place the sedimentation device body 1 on a flat and open ground. Further, introduce sewage into the filter grille 3 through a pipeline, so that the sewage passes through the filter grille 3 and enters the water storage tank 101. The filter grille 3 filters large impurities in the sewage, avoiding them from entering the subsequent treatment process and reducing the risk of equipment blockage.

[0047] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on the above Embodiment 1. The existing stirring shaft may not be able to cover all areas, and cannot make the sewage and chemical reagents fully mixed and contacted, resulting in poor mixing effect and affecting the sewage treatment effect. This technical solution is as Figure 1 and Figures 3 - 5 As shown, it discloses a mixing component of the sedimentation device. The chute 4 is provided on the sedimentation device body 1. A slider 5 is arranged in the chute 4, and a bracket 6 is fixedly connected to the upper end of the slider 5. An electric push rod 7 is fixedly connected to the bracket 6, and a push plate 8 is fixedly connected to the output end of the electric push rod 7. The water storage tank 101 is provided in the sedimentation device body 1. The water delivery pipe 9 is fixedly arranged on the side wall of the push plate 8. Nozzles 10 are arranged on the water delivery pipe 9, and a fixed sleeve 11 is fixedly connected to the outer wall of the nozzle 10. An elastic telescopic rod 12 is fixedly connected to the side wall of the fixed sleeve 11, and a sealing plug 13 is rotatably connected to the end of the elastic telescopic rod 12 away from the fixed sleeve 11. A stirring rod 14 is fixedly connected to the outer wall of the sealing plug 13, and a slot 15 is opened on the sealing plug 13. Two sets of the chute 4, the slider 5, the bracket 6 and the electric push rod 7 are symmetrically arranged with respect to the sedimentation device body 1, and the chute 4 is slidably connected to the slider 5. The bottom surface of the water storage tank 101 is inclined, and the push plate 8 is slidably arranged in the water storage tank 101. And the push plate 8 is made of a metal material structure. The push plate 8 includes a first baffle 801 and a second baffle 802. A rectangular groove 803 is opened at the bottom end of the first baffle 801, and the second baffle 802 is slidably arranged in the rectangular groove 803. An auxiliary spring 804 is connected between the first baffle 801 and the second baffle 802, and an elastic telescopic structure is formed between the first baffle 801 and the second baffle 802 through the auxiliary spring 804. And a group of through holes 805 are opened on the first baffle 801. An inlet is opened on the water delivery pipe 9, and a plurality of nozzles 10 on the water delivery pipe 9 are arranged in an array, and the nozzles 10 correspond to the sealing plug 13. The slot 15 on the sealing plug 13 is provided with an inclined surface, and a plurality of the slot 15 and the stirring rods 14 are arranged in a circumferential array with respect to the center point of the sealing plug 13.

[0048] In this technical solution, as Figure 1 shown, by setting the sealing plug 13 and the stirring rod 14, when the second baffle 802 slowly contracts into the first baffle 801, it will drive the water delivery pipe 9 to move synchronously, and then spray the flocculant solution on the sewage at different depths through the nozzle 10, ensuring that the sewage and the flocculant solution are fully mixed. At the same time, part of the solution will be ejected from the slot 15 on the sealing plug 13, causing the sealing plug 13 to drive the stirring rod 14 to rotate, further improving the mixing uniformity.

[0049] It adopts the technical solution as Figures 3 - 5 shown. First, in the initial state, the push plate 8 is located at the end of the water storage tank 101 away from the filter grille 3. Immediately after the sewage in the water storage tank 101 stands still for a period of time, the electric push rod 7 is started. The electric push rod 7 will push the first baffle 801 to move, causing the first baffle 801 to drive the second baffle 802 to move slowly. The second baffle 802 will slide along the surface of the water storage tank 101, thus pushing the sewage and the impurities deposited at the bottom to move simultaneously. Since the bottom surface of the water storage tank 101 is inclined, the second baffle 802 will slide into the first baffle 801 during the movement and squeeze the auxiliary spring 804 to contract, and the liquid level of the sewage will gradually rise, and then pass through the through hole 805 and be discharged to the other side of the first baffle 801 and the second baffle 802;

[0050] During the process of the first baffle 801 driving the second baffle 802 to move slowly, through an external pump, the pump conveys the mixed flocculant solution water into the water delivery pipe 9 through a pipeline. The solution in the water delivery pipe 9 will enter the nozzle 10, thereby pushing the sealing plug 13, causing the sealing plug 13 to pull the elastic telescopic rod 12 to extend and open the nozzle 10. At this time, the solution will be sprayed from the nozzle 10 into the sewage and mixed with the sewage. And part of the solution sprayed from the nozzle 10 will be ejected from the slot 15 on the sealing plug 13, thereby driving the sealing plug 13 to rotate, causing the sealing plug 13 to drive the stirring rod 14 to rotate and stir the sewage, improving the mixing uniformity. When not in use, the sealing plug 13 will move back under the action of the elastic telescopic rod 12 and then fit with the nozzle 10 to prevent the nozzle 10 from being blocked by impurities and improve the service life of the device.

[0051] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1 and Embodiment 2. After the precipitation is completed, most of the impurities will accumulate at the bottom of the device, and it takes a lot of time for workers to clean the impurities deposited at the bottom of the device, increasing the workload of the workers. To further solve this technical problem, this technical solution is as Figure 2 and Figures 4 - 12As shown in the figure, the gathering component of the precipitation device is disclosed. The blocking mechanism 16 is arranged at the upper end of the push plate 8 and is used to gather impurities in the sewage. The shaft rod 17 is fixedly installed on the side wall of the precipitation device body 1. A blocking piece 18 is sleeved outside the shaft rod 17. The bottom end of the blocking piece 18 is rotatably connected to a pull rod 19, and one end of the pull rod 19 away from the blocking piece 18 is rotatably connected to a moving piece 20. The electromagnet 22 is fixedly arranged on the filter grille 3. The blocking mechanism 16 includes a fixed rod 1601. The fixed rod 1601 is rotatably arranged on the first baffle 801. A filter plate 1602 is fixedly nested outside the fixed rod 1601. Two fixing blocks 1603 are symmetrically and fixedly installed on the outer wall of the filter plate 1602. Connecting grooves are formed on the side walls of the two fixing blocks 1603 facing each other, and a floating plate 1604 is slidably connected in the connecting grooves. A first accommodating groove 1605 is formed in the floating plate 1604. A driving gear 1606 is rotatably installed in the first accommodating groove 1605. A torsion spring 21 that provides a reset elastic force is connected between the fixed rod 1601 and the first baffle 801. The filter plate 1602 on the fixed rod 1601 is attached to the side wall of the first baffle 801, and the filter plate 1602 corresponds to the through hole 805. The floating plate 1604 is connected to the bracket 6 through a pull rope. The blocking mechanism 16 further includes a housing 1607. The housing 1607 is fixedly arranged on the outer wall of the floating plate 1604. A micro motor 1608 is fixedly installed in the housing 1607, and the output end of the micro motor 1608 penetrates into the first accommodating groove 1605 and is fixedly connected to the driving gear 1606. There are two second accommodating grooves 1609. Scraping plates 1610 are slidably connected in the two second accommodating grooves 1609. Rotating sleeves 1611 are fixedly connected to the two scraping plates 1610, and spiral grooves 1612 are formed in the rotating sleeves 1611. A rack 1613 is slidably arranged in the first accommodating groove 1605. A guide rod 1614 is fixedly connected to the side wall of the rack 1613. A tooth block 1615 is sleeved outside the guide rod 1614. A top rod 1616 is fixedly connected to the upper end of the tooth block 1615. One end of the top rod 1616 away from the tooth block 1615 penetrates into the rotating sleeve 1611, and a protruding block 1617 is fixedly connected to the outer wall of the top rod 1616. There are two racks 1613 symmetrically arranged with respect to the driving gear 1606. The top rods 1616 on the racks 1613 are slidably connected to the tooth blocks 1615. A compression spring 1618 is connected between the tooth block 1615 and the rack 1613, and the tooth block 1615 and the rack 1613 form an elastic telescopic structure through the compression spring 1618, and the compression spring 1618 is sleeved outside the guide rod 1614. The tooth block 1615 and the rack 1613 are both meshed with the driving gear 1606. One end of the rotating sleeve 1611 away from the scraping plate 1610 penetrates into the first accommodating groove 1605, and the part of the rotating sleeve 1611 extending into the first accommodating groove 1605 is rotatably connected between the outer walls of the floating plate 1604 and the rack 1613, and the rotating sleeve 1611 is slidably connected to the top rod 1616.One end of the convex block 1617 on the ejector rod 1616 extends into the spiral groove 1612, and the convex block 1617 is slidably connected to the spiral groove 1612. The shaft rods 17, the blocking members 18, the pull rods 19 and the moving members 20 are all symmetrically arranged in two with respect to the sedimentation device body 1. Both of the two shaft rods 17 are rotatably connected to the blocking members 18, and a second torsion spring 21 that provides a reset elastic force is connected between the shaft rod 17 and the sedimentation device body 1. The upper end of the blocking member 18 is attached to the side wall of the bracket 6. The moving member 20 is slidably connected to the side wall of the filter grille 3, and the moving member 20 corresponds to the first baffle 801, and the first baffle 801 is aligned with the electromagnet 22.,

[0052] In this technical solution, as Figure 2 shown, by setting the floating plate 1604, when the first baffle 801 fits with the filter grille 3, it will reversely push the electric push rod 7 to move, so that the electric push rod 7 drives the bracket 6 to move while pulling the floating plate 1604, thereby gathering the impurities floating on the sewage surface, facilitating the subsequent cleaning by the staff. And the micro motor 1608 will drive the driving gear 1606 to rotate, so that the driving gear 1606 meshes with the rack 1613 to move, and then drives the rotating sleeve 1611 to move through the rack 1613. Finally, the rotating sleeve 1611 pushes the scraper 1610 to fit with the inner wall of the water storage tank 101 to clean the inner wall of the water storage tank 101, reducing manual intervention, improving work efficiency, facilitating the subsequent cleaning work by the staff, and reducing the cleaning time and difficulty.

[0053] It adopts the technical solution as Figures 4 - 12 shown. First, the first baffle 801 will squeeze the moving member 20, so that the moving member 20 slides backward along the filter grille 3, and then pulls the pull rod 19 to move, so that the pull rod 19 pulls the blocking member 18 to rotate. When the moving member 20 is flush with the filter grille 3, it stops moving. At this time, the first baffle 801 fits with the filter grille 3 and then stops moving. The blocking member 18 is separated from the bracket 6. Immediately afterwards, the electric push rod 7 will continue to push the first baffle 801, so that the slider 5 drives the electric push rod 7 to move reversely along the chute 4, and then pulls the pull rope, so that the pull rope pulls the floating plate 1604. The floating plate 1604 will drive the fixed rod 1601 and the filter plate 1602 to rotate through the fixing block 1603. Since the filter plate 1602 is located below the filter grille 3, it will not affect the rotation of the filter plate 1602. Immediately afterwards, when the floating plate 1604 rotates to the horizontal state, the floating plate 1604 will slide outward along the fixing block 1603, so as to disengage from the fixing block 1603 and fall to the sewage surface. At this time, the fixed rod 1601 rotates back under the drive of the torsion spring 21, so that the filter plate 1602 hits the first baffle 801 to shake off the impurities attached to the surface of the filter plate 1602;

[0054] When the floating plate 1604 floats on the surface of the sewage, the micro-motor 1608 starts at this time, thereby driving the driving gear 1606 to rotate. The driving gear 1606 will engage and drive the rack 1613 to move, so that the rack 1613 drives the rotating sleeve 1611 to move. The rotating sleeve 1611 will drive the scraper 1610 to move out of the second accommodating groove 1609. When the scraper 1610 is in contact with the inner wall of the water storage tank 101, at this time, the driving gear 1606 intermittently engages with the tooth block 1615, thereby driving the tooth block 1615 to slide along the guide rod 1614, so that the tooth block 1615 compresses the compression spring 1618 and drives the ejector rod 1616 to move. After the driving gear 1606 is separated from the tooth block 1615, the elastic force of the compression spring 1618 causes the tooth block 1615 to reset. In this way, the ejector rod 1616 reciprocally moves along the inner wall of the rotating sleeve 1611, and further drives the convex block 1617 to reciprocally move along the spiral groove 1612, so that the rotating sleeve 1611 drives the scraper 1610 to rotate while being in contact with the inner wall of the water storage tank 101 for cleaning. And the pull rope will pull the floating plate 1604 to move, so that the floating plate 1604 will drive the impurities floating on the surface of the sewage to gather together, which is convenient for the subsequent cleaning by the staff.

[0055] Through the setting of the water pump 2, after the sewage sedimentation is completed, the upper layer of clean water can be transported from the water storage tank 101 to the next treatment stage for further purification or treatment. After the sewage in the water storage tank 101 is emptied, at this time, the electromagnet 22 is energized, so that the electromagnet 22 attracts the first baffle 801. Immediately, the electric push rod 7 is started. The electric push rod 7 will drive the slider 5 to reset and move along the sliding groove 4. When the slider 5 abuts against the end of the sliding groove 4 and stops moving, the electric push rod 7 pulls the first baffle 801 to move, and the first baffle 801 is separated from the electromagnet 22, thereby driving the first baffle 801 to reset and move. Through the elastic force of the auxiliary spring 804, the second baffle 802 will slide while being in contact with the bottom surface of the water storage tank 101, so that the second baffle 802 gathers the impurities deposited on the lower surface of the water storage tank 101 together, which is convenient for the cleaning by the staff.
