Description

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

[0002] Wastewater from fruit factories primarily comes from cleaning water, rinsing water, cooling water, and process wastewater used during the production process. This wastewater often contains high levels of organic matter, sugars, fruit pulp, peel, and small amounts of acidic and alkaline substances. During the treatment process, pretreatment is required before aerobic biological treatment. Pretreatment primarily involves using sedimentation tanks to achieve natural precipitation of impurities. However, since these impurities contain fruit pulp, peel, and other impurities, these impurities easily adsorb to the bottom of the tank, making them difficult to clean and treat later. Furthermore, fruit peel and pulp can be decomposed by subsequent aerobic organisms. Therefore, after being salvaged from the sedimentation tank, they are still discarded into aerobic biological tanks for treatment. However, their greater gravity makes them easily sink to the bottom, making it difficult for aeration to effectively affect the bottom, resulting in low wastewater treatment efficiency.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] like Figures 1-8The sewage purification treatment device shown in the figure includes an aeration tank 31, a sedimentation tank 1 is fixedly installed on the front upper side of the aeration tank 31, the inner side of the sedimentation tank 1 is connected to two traveling frames 13 through a moving mechanism, and the lower ends of the two traveling frames 13 are connected to a rotating shaft 2 through a driving mechanism. The outer surface of the rotating shaft 2 is fixedly sleeved with a plurality of knife seats 3, and the outer surface of the knife seats 3 is fixedly connected to a plurality of concave knives 4, and a knife edge 5 is provided at the edge of the concave knife 4. A cover plate 6 is fixedly connected between the two traveling frames 13, and the cover plate 6 is located on the rotating shaft. 2, a plurality of fixed knives 8 are fixedly connected to the lower surface of the cover plate 6, and a front baffle 7 extending toward the front is fixedly connected to the lower side of the cover plate 6. A rear baffle 11 is fixedly installed on the rear of the two traveling frames 13, and an arc-shaped plate 12 is fixedly connected to the upper end of the rear baffle 11. The rear end of the sedimentation tank 1 is vertically slidably connected to a gate plate 34, and guide bars 24 are fixedly installed on both sides of the gate plate 34. The outer surface of the guide bar 24 is provided with an inclined portion 25, and the side end of the traveling frame 13 slides with the surface of the guide bar 24 through a guide sleeve mechanism.

[0027] like Figure 2 、 Figure 3 As shown, the moving mechanism includes a side seat 18 fixedly connected to the upper end of the traveling frame 13, a screw rod 20 is rotatably connected to the upper edge of one side surface of the sedimentation tank 1, and a guide rod 23 is fixedly connected to the upper edge of the other side surface of the sedimentation tank 1. The side surface of one side seat 18 is fixedly connected to a threaded sleeve 19, and the screw rod 20 is threadedly connected to the inner side of the threaded sleeve 19. The side surface of the other side seat 18 is fixedly connected to a sliding sleeve 22, and the sliding sleeve 22 is slidingly provided on the outer surface of the guide rod 23. The front end of the screw rod 20 is fixedly connected to the output shaft of the servo motor 21, and the servo motor 21 is fixedly installed on the side surface of the sedimentation tank 1. When the traveling frame 13 moves back and forth, the sliding sleeve 22 will slide along the surface of the guide rod 23 to improve the stability of the traveling frame 13 during movement.

[0028] like Figure 2 、 Figure 7 、 Figure 8 As shown, the guide sleeve mechanism includes two guide wheels 28 rotatably mounted on the inner side of the side seat 18. A reinforcement seat 29 is fixedly mounted on the lower end of the side seat 18. The lower guide wheel 28 slides on the upper surface of the reinforcement seat 29, protecting the lower guide wheel 28 from being exposed to the outside. The two guide wheels 28 on each side are located on the upper and lower surfaces of the guide bar 24, respectively. When the two guide wheels 28 on each side move back and forth and contact the inclined portion 25, they cause the guide bar 24 to move up and down.

[0029] like Figure 7As shown, the drive mechanism includes a motor base 14 fixedly mounted on the upper end of a traveling frame 13. A drive motor 15 is fixedly mounted on the upper surface of the motor base 14. One end of the rotating shaft 2 and the output shaft of the drive motor 15 are respectively fixedly connected to a transmission wheel 16. The outer sides of the two transmission wheels 16 are jointly covered with a transmission belt 17 to provide power for the rotation of the rotating shaft 2.

[0030] like Figure 3 As shown, the rear ends of the guide bars 24 on both sides are fixedly connected to a transverse connecting rod 35, which is fixedly connected to the rear surface of the gate plate 34 to improve the installation stability between the guide bars 24 and the gate plate 34.

[0031] like Figure 7 As shown, the two side surfaces of the sedimentation tank 1 are fixedly connected with fixed plates 27, and the upper surface of the fixed plates 27 is fixedly connected with a plurality of vertical rods 26, which slide through the surface of the guide bar 24. The vertical rods 26 play a guiding role and improve the stability of the movement of the guide bar 24.

[0032] like Figure 5 、 Figure 6 As shown, the upper end of the fixed blade 8 is fixedly connected to the mounting base 9, and the upper end of the mounting base 9 is fixedly mounted on the lower surface of the cover plate 6. The two sides of the rear baffle 11 are respectively fixedly connected to the connecting plates 10, and the front ends of the side surfaces of the connecting plates 10 are fixedly connected to the outer surface of the traveling frame 13 to ensure the stable installation of the fixed blade 8.

[0033] like Figure 1 、 Figure 2 As shown, a water inlet pipe 30 is fixedly mounted on the front upper side of the sedimentation tank 1, a drain pipe 33 is fixedly mounted on the rear surface of the aeration tank 31, and an aeration mechanism 32 is provided on the inner bottom surface of the aeration tank 31. Aeration mechanism 32 is conventional and will not be described in detail. The aerated wastewater is discharged through drain pipe 33 for further treatment.

[0034] Sewage enters through the water inlet pipe 30 and reaches the sedimentation tank 1. The pulp and peel impurities will be precipitated, and the water will overflow through the upper side of the gate plate 34 and flow into the aeration tank 31 for aerobic biological treatment. The drive motor 15 and the servo motor 21 are regularly controlled to rotate. The drive motor 15 rotates under the transmission action of the transmission wheel 16 and the transmission belt 17, so that the rotating shaft 2 rotates, and then the concave knife 4 rotates. Due to the concave shape of the concave knife 4, when it rotates, in addition to cutting the peel and pulp, it also causes the water flow to flip toward the rear and upper part. At the same time, due to the presence of the cover plate 6, it plays a role in guiding the flow of water. When the broken impurities reach the upper rear part of the rotating shaft 2, they will follow the upper surface of the curved plate 12 And it slides down, and cooperates with the blocking effect of the rear baffle 11 on the water flow, effectively preventing impurities from repeatedly entering the concave knife 4. The servo motor 21 rotates, causing the screw 20 to rotate, and then drives the threaded sleeve 19 to move forward, that is, the concave knife 4 will move forward while rotating, so as to fully cut and guide the flow of the precipitated impurities. When it reaches the front, the drive motor 15 stops rotating, and the servo motor 21 reverses, causing the traveling frame 13 to move backward, and the rear baffle 11 will push the settled broken pulp and peel. During the pushing, the water flow flips, and when it flips up in accordance with the rear baffle 11, a vortex will be formed under the guidance of the lower surface of the arc plate 12, thereby preventing impurities from flipping up to the front of the rotating shaft 2, and effectively helping the impurities to flow toward the rear.

[0035] It should be added that when the traveling frame 13 just starts to move forward, the two guide wheels 28 will guide the inclined portion 25 to move upward relative to each other, that is, the guide bars 24 on both sides move upward, so that the gate 34 is opened. During the forward movement, the sewage and impurities in the sedimentation tank 1 move toward the rear, which can assist in the discharge of the broken impurities. Subsequently, when the traveling frame 13 moves backward, the pushing effect of the rear baffle 11 will also assist in the discharge of the broken impurities. Since the inclined portion 25 is arranged close to the rear, the timing of the gate 34 descending is as slow as possible, thereby ensuring the full discharge of sewage. In the discharged sewage, since the impurities are broken, it is easier to churn with the aeration mechanism 32, avoiding sedimentation problems, thereby promoting the efficiency of aerobic decomposition.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
