Description

Technical Field

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

[0002] The sewage from fruit factories mainly comes from the cleaning water, rinsing water, cooling water and process wastewater used in the production process. These sewage often contain high levels of organic matter, sugar, pulp, peel and a small amount of acid and alkali substances. In the treatment process, pretreatment is required before aerobic biological treatment. In the pretreatment, the natural precipitation of impurities is mainly achieved through the sedimentation tank, but because the impurities contain impurities such as pulp and peel, these impurities are easily adsorbed on the bottom of the pool, making it difficult to clean and treat them later. In addition, the peel and pulp can be decomposed by subsequent aerobic organisms. Therefore, after being salvaged from the sedimentation tank in the later stage, they will still be thrown into the aerobic biological pool for treatment, but their gravity is large and they are easy to sink to the bottom.

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

[0026] like Figure 1-Figure 8The sewage purification treatment device shown in the figure comprises an aeration tank 31, a sedimentation tank 1 is fixedly installed on the front upper side of the aeration tank 31, two traveling frames 13 are connected to the inner side of the sedimentation tank 1 through a moving mechanism, a rotating shaft 2 is connected to the lower ends of the two traveling frames 13 through a driving mechanism, a plurality of knife seats 3 are fixedly sleeved on the outer surface of the rotating shaft 2, a plurality of concave knives 4 are fixedly connected to the outer surface of the knife seats 3, a knife edge 5 is arranged 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, a front baffle 7 extending forward 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, an arc plate 12 is fixedly connected to the upper end of the rear baffle 11, a gate plate 34 is vertically slidably connected to the rear end of the sedimentation tank 1, guide bars 24 are fixedly installed on both sides of the gate plate 34, an inclined portion 25 is provided on the outer surface of the guide bar 24, and the side ends of the traveling frame 13 are slidably matched 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 end of the other side surface of the sedimentation tank 1. A threaded sleeve 19 is fixedly connected to the side surface of one side seat 18, and the screw rod 20 is threadedly connected to the inner side of the threaded sleeve 19. A sliding sleeve 22 is fixedly connected to the side surface of the other side seat 18. The sliding sleeve 22 is slidingly set 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 forward and backward, the sliding sleeve 22 will slide along the surface of the guide rod 23 to improve the stability of the side 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, and a reinforcement seat 29 is fixedly embedded at the lower end of the side seat 18. The lower guide wheel 28 is slidably embedded on the upper surface of the reinforcement seat 29, which protects the lower guide wheel 28 and prevents it from being exposed to the outside. The two guide wheels 28 on each side are respectively located on the upper and lower surfaces of the guide bar 24. When the two guide wheels 28 on each side move forward and backward to contact the inclined portion 25, the guide bar 24 will move up and down.

[0029] like Figure 7As shown, the driving mechanism includes a motor seat 14 fixedly mounted on the upper end of a traveling frame 13, a driving motor 15 is fixedly mounted on the upper surface of the motor seat 14, one end of the rotating shaft 2 and the output shaft of the driving motor 15 are respectively fixedly connected with a transmission wheel 16, and the outer sides of the two transmission wheels 16 are jointly sleeved 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 with a transverse connecting rod 35, and the transverse connecting rod 35 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 respectively fixedly connected with fixed plates 27, and the upper surface of the fixed plate 27 is fixedly connected with a plurality of vertical rods 26, and the vertical rods 26 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 knife 8 is fixedly connected with a mounting seat 9, the upper end of the mounting seat 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 with connecting plates 10, and the front end of the side surface of the connecting plate 10 is fixedly connected to the outer surface of the traveling frame 13 to ensure the stable installation of the fixed knife 8.

[0033] like Figure 1 , Figure 2 As shown, a water inlet pipe 30 is fixedly installed on the front upper side of the sedimentation tank 1, a drain pipe 33 is fixedly installed 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. The aeration mechanism 32 is a prior art, and will not be described in detail. The sewage treated by aeration is discharged through the drain pipe 33 for the next step of treatment.

[0034] Sewage enters through the water inlet pipe 30 and reaches the sedimentation tank 1, where pulp and peel impurities will precipitate, and water overflows from the upper side of the gate plate 34 and flows 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 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 side. 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 side of the shaft 2, they will follow the upper surface of the curved plate 12. And it slides down, cooperates with the blocking effect of the rear baffle 11 on the water flow, effectively prevents impurities from repeatedly entering the concave knife 4, and the servo motor 21 rotates, so that the screw rod 20 rotates, and then drives the threaded sleeve 19 to move forward, that is, the concave knife 4 rotates and moves forward at the same time, 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, so that the traveling frame 13 moves backward, and the rear baffle 11 pushes the settled broken pulp and peel. During the pushing, the water flow flips, and when the rear baffle 11 flips up, a vortex is formed under the guidance of the lower surface of the arc plate 12, thereby preventing the 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 relatively, 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. Later, 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 tumble 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 only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
