Description

Technical Field

[0001] The invention relates to the technical field of phosphorus removal equipment, in particular to industrial sewage phosphorus removal equipment. Background Art

[0002] The phosphorus in industrial wastewater mainly comes from raw materials, intermediates, products and by-products used in the production process, especially fertilizers, medicines, metal surface treatment, fiber dyeing and fermentation, and food industries. The presence of phosphorus can lead to eutrophication of water bodies and affect water quality and the ecological environment. Therefore, industrial wastewater needs to be treated for phosphorus removal before discharge.

[0003] In the process of phosphorus removal from sewage, chemical precipitation method and chemical flocculation method are usually used, among which chemical flocculation method is more common. By adding flocculants into the flocculation tank, the flocs formed by the flocculants adsorb and capture phosphorus particles, thereby separating them from the water, which can improve the phosphorus removal efficiency.

[0004] When using flocculants to remove phosphorus from industrial wastewater in a flocculation tank, the wastewater in the flocculation tank needs to be stirred. During stirring, the floccules formed by the adsorption of phosphorus particles by the flocculants float or suspend in the flocculation tank. Too low stirring intensity will cause the floc structure to be loose and the strength to be low, which is not conducive to sedimentation and removal; while too high stirring intensity will cause the flocs to break, which is also not conducive to sedimentation and removal. For this reason, we propose an industrial wastewater phosphorus removal equipment. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figure 1-8 , the present invention provides a technical solution: an industrial wastewater phosphorus removal device, comprising a flocculation tank body 1, a motor 11 is carried on the flocculation tank body 1, and the motor 11 is used to stir the inside of the flocculation tank body 1;

[0036] A stirring rod 2, the stirring rod 2 is located inside the flocculation tank body 1, the stirring rod 2 is fixedly connected to the output end of the motor 11 and is rotatably connected to the flocculation tank body 1;

[0037] A stirring mechanism 3, the stirring mechanism 3 is located inside the flocculation tank body 1, and the stirring mechanism 3 can stir the inside of the flocculation tank body 1 through the stirring rod 2;

[0038] The scraping mechanism 4 is located inside the stirring rod 2 and can scrape the floccules on the surface of the stirring rod 2;

[0039] When the present invention is in use, the motor 11 drives the stirring mechanism 3 to stir the inside of the flocculation tank body 1 through the stirring rod 2, so that the flocculant and sewage inside the flocculation tank body 1 are fully mixed, and the stirring mechanism 3 alternately passes through stirring tracks 1 12 and stirring tracks 2 13 of different sizes to avoid excessive shearing of the inside of the flocculation tank body 1 by the stirring mechanism 3, thereby causing the floccules to be broken.

[0040] The stirring mechanism 3 includes a fixed box 31 fixedly connected to the outer wall of the stirring rod 2, two stirring rods 32 are fixedly connected to the outer wall of the fixed box 31, a stirring groove 33 is provided below the stirring rod 32, a fixed rod 34 is fixedly connected to the inner wall of the stirring groove 33, a stirring plate 35 is rotatably connected to the outer periphery of the fixed rod 34, a stirring track 12 and a stirring track 2 13 are provided on the inner wall of the flocculation tank body 1, the stirring track 12 and the stirring track 2 13 are connected, the stirring track 12 and the stirring track 2 13 are both semicircular, the end of the stirring rod 32 away from the fixed box 31 is located inside the stirring track 12, the stirring track 12 is slightly larger than the stirring track 2 13, and the corners between the stirring track 12 and the stirring track 2 13 are rounded;

[0041] After starting the motor 11, the motor 11 drives the stirring rod 32 to rotate through the stirring rod 2. When the stirring rod 32 is located inside the stirring track 12, the stirring plate 35 is in a vertical state. At this time, the stirring plate 35 drives the sewage inside the flocculation tank body 1 to stir. When the stirring rod 32 enters the stirring track 2 13 from the stirring track 12, the stirring plate 35 abuts against the inner wall of the stirring track 2 13. At this time, the stirring plate 35 rotates around the fixed rod 34 inside the stirring tank 33. The stirring plate 35 is in a horizontal state. At this time, the stirring plate 35 no longer stirs the sewage. When the stirring rod 32 enters the stirring track 12 from the stirring track 2 13, the stirring plate 35 rotates around the fixed rod 34 to reset the stirring plate 35, so that the stirring plate 35 is in an intermittent stirring state (half circle stirring, half circle folding).

[0042] Intermittent stirring controls the formation and stability of flocs by periodically changing the stirring intensity. This method can effectively avoid excessive shearing and prevent excessive shearing and breakage of flocs caused by continuous high-intensity stirring, which is not conducive to the formation of flocs. Intermittent stirring allows flocs to have enough time to grow and coagulate at a lower stirring intensity to form flocs with a dense structure and larger size. Such flocs are easier to settle and separate solid-liquid, and are more conducive to wastewater phosphorus removal.

[0043] The scraping mechanism 4 includes a rotating hole 41 opened at one end of the stirring rod 32 close to the flocculation tank body 1, a reciprocating screw 42 is rotatably connected inside the rotating hole 41, and a roller 43 is fixedly connected to the end of the reciprocating screw 42 away from the fixed box 31, the roller 43 is located inside the stirring track 12 and close to the inner wall of the stirring track 12, a retaining ring 44 is fixedly connected to the inner wall of the stirring tank 33, the retaining ring 44 is located at the periphery of the reciprocating screw 42 and is rotatably connected to the reciprocating screw 42, a sliding box 45 is arranged around the reciprocating screw 42, the sliding box 45 is threadedly connected to the reciprocating screw 42, and a limiting member 5 capable of limiting the sliding box 45 is provided on one side of the sliding box 45, the limiting member 5 includes a through hole 51 opened in the sliding box 45, and a limiting rod 52 is slidably connected inside the through hole 51, one end of the limiting rod 52 is fixedly connected to the inner wall of the stirring tank 33, and the other end of the limiting rod 52 is fixedly connected to the outer wall of the fixed box 31;

[0044] When the motor 11 drives the stirring rod 32 to slide on the inner wall of the stirring track 12 through the stirring rod 2, the roller 43 is close to the inner wall of the stirring track 12. When the stirring rod 32 moves, the roller 43 moves close to the inner wall of the stirring track 12. At this time, the roller 43 is located at the end of the stirring rod 32 and rotates. When the roller 43 rotates, it drives the reciprocating screw 42 to rotate. Since there is a limiting rod 52 inside the through hole 51 opened in the sliding box 45, the sliding box 45 is located at the outer periphery of the reciprocating screw 42 and slides. When the reciprocating screw 42 slides back and forth, the surface of the stirring plate 35 can be cleaned by the scraper 6.

[0045] A scraper 6 capable of scraping the stirring plate 35 is provided at one end of the sliding box 45 away from the limiting rod 52. The scraper 6 includes two support plates 61 fixedly connected to the outer wall of the sliding box 45. The two support plates 61 are located at one end of the sliding box 45 away from the limiting rod 52. The two support plates 61 are fixedly connected by a support rod 62. A torsion spring 63 is fixedly connected to the outer wall of the support rod 62. A scraper 64 is fixedly connected to one end of the torsion spring 63 away from the support rod 62. The scraper 64 is rotatably connected to the support rod 62.

[0046] When the stirring plate 35 is in a vertical state, the scraper 64 is in close contact with the surface of the stirring plate 35, and the surface of the stirring plate 35 is scraped and cleaned when the sliding box 45 slides around the reciprocating screw rod 42 to prevent the flocculants from adhering to the surface of the stirring plate 35; when the stirring plate 35 is changed from a vertical state to a horizontal state, the stirring plate 35 rotates around the fixed rod 34, and the stirring plate 35 lifts up the scraper 64, and the scraper 64 rotates around the support rod 62, and the torsion spring 63 accumulates force. Since the scraper 64 is V-shaped, the scraper 64 is in close contact with the outer wall of the stirring plate 35, and the scraper 64 can always scrape and clean the outer wall of the stirring plate 35 The stirring plate 35 is clean and the scraper 64 can scrape both sides of the stirring plate 35; when the stirring plate 35 is changed from a horizontal state to a vertical state, the torsion spring 63 is reset to drive the stirring plate 35 to rotate around the fixed rod 34, and the stirring plate 35 is abutted by the torsion spring 63 to drive the sewage to stir. By adjusting the intermittent stirring cycle, the mixing of flocculant and suspended particles in the sewage can be optimized, and the collision probability between particles can be increased, thereby improving the flocculation effect. In addition, an appropriate intermittent stirring strategy can reduce the amount of flocculant used, thereby reducing the waste of flocculant caused by excessive stirring and reducing the cost of phosphorus removal.

[0047] Embodiment 2

[0048] See also Figure 9-11 The fixed box 31 is provided with a telescopic hole 7, a spring 71 is fixedly connected to the inner wall of the fixed box 31, a sleeve 72 is fixedly connected to the end of the spring 71 away from the fixed box 31, the sleeve 72 is located inside the telescopic hole 7 and is slidably connected to the telescopic hole 7, a connecting rod 73 is fixedly connected to the outer wall of the sleeve 72, the connecting rod 73 is located outside the fixed box 31, and a baffle 74 is fixedly connected to the end of the connecting rod 73 away from the sleeve 72, the baffle 74 is arc-shaped, and a plurality of circular holes 75 are provided on the surface of the baffle 74, and a vertical rod 76 is fixedly connected to the outer wall of the sleeve 72;

[0049] When the stirring plate 35 is in a horizontal state, the stirring rod 32 is located inside the flocculation tank body 1 and rotates to collect flocs through the arc-shaped baffle 74. When the flocs are small, the flocs leak out from the circular hole 75 opened by the baffle 74. At this time, the baffle 74 does not move, and the sleeve 72 does not move, and the vertical rod 76 does not move. At this time, the operator can clearly observe that the flocs are not coagulated. When the flocs are large, the stirring rod 32 drives the baffle 74 to collect the flocs when it rotates. The flocs are accumulated inside the baffle 74 and cannot pass through the circular hole 75. At this time, the baffle 74 is located in the sewage and has a large rotation resistance. The baffle 74 drives the sleeve 72 to compress the spring 71 through the connecting rod 73. At this time, the sleeve 72 is displaced. When the vertical rod 76 is displaced, it can remind the operator that the flocculation inside the flocculation tank body 1 is sufficient, which is convenient for entering the next step.
