Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of phosphorus removal equipment, in particular to an industrial wastewater phosphorus removal equipment. BACKGROUND

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

[0003] In the process of wastewater phosphorus removal, chemical precipitation method, chemical flocculation method and the like are usually used, among which the chemical flocculation method is more common. By adding flocculants to the flocculation tank, the flocculants form flocculation bodies that 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 the flocculation tank, the wastewater in the flocculation tank needs to be stirred. During stirring, the flocculation bodies formed by the adsorption of phosphorus particles by flocculants float or suspend in the flocculation tank. Too low stirring intensity can cause the flocculation body structure to be loose and low in intensity, which is not conducive to sedimentation removal. Too high stirring intensity can cause the flocculation body to break, which is also not conducive to sedimentation removal. Therefore, we propose an industrial wastewater phosphorus removal equipment. SUMMARY

[0005] The present application aims to provide an industrial wastewater phosphorus removal equipment to solve the problems of too low stirring intensity causing the flocculation body structure to be loose and low in intensity, which is not conducive to sedimentation removal, and too high stirring intensity causing the flocculation body to break, which is also not conducive to sedimentation removal.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] Embodiment one

[0035] Please refer to Figures 1-8 The present application provides a technical solution: an industrial wastewater phosphorus removal equipment, including a flocculation tank body 1, a motor 11 is carried above the flocculation tank body 1, and the motor 11 is used for stirring the inside of the flocculation tank body 1.

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

[0037] A 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] A scraping mechanism 4 is located inside the stirring rod 2, and the scraping mechanism 4 can scrape the flocculation body on the surface of the stirring rod 2.

[0039] When the present application is used, 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 in the inside of the flocculation tank body 1 is fully mixed with the wastewater. The stirring mechanism 3 alternately passes through the stirring track one 12 and the stirring track two 13 of different sizes, so as to avoid excessive shearing of the inside of the flocculation tank body 1 by the stirring mechanism 3, thereby preventing the flocculation body from being broken.

[0040] The stirring mechanism 3 includes a fixed box 31 fixedly connected with the outer wall of the stirring rod 2, two stirring rods 32 fixedly connected with the outer wall of the fixed box 31, a stirring groove 33 opened below the stirring rod 32, a fixed rod 34 fixedly connected with the inner wall of the stirring groove 33, a stirring plate 35 rotationally connected with the outer periphery of the fixed rod 34, and stirring tracks one 12 and two 13 opened in the inner wall of the flocculation tank body 1. The stirring track one 12 and the stirring track two 13 are communicated, both of which are semicircular. The end of the stirring rod 32 away from the fixed box 31 is located inside the stirring track one 12, the stirring track one 12 is slightly larger than the stirring track two 13, and the stirring track one 12 and the stirring track two 13 are chamfered between them.

[0041] When the motor 11 is started, the motor 11 drives the stirring rod 32 to rotate through the stirring rod 2, when the stirring rod 32 is located in the stirring track one 12, the stirring plate 35 is in a vertical state, at this time, the stirring plate 35 drives the sewage in the flocculation tank main body 1 to stir, when the stirring rod 32 enters the stirring track two 13 from the stirring track one 12, the stirring plate 35 abuts against the inner wall of the stirring track two 13, at this time, the stirring plate 35 rotates around the fixed rod 34 and is located in the stirring groove 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 one 12 from the stirring track two 13, the stirring plate 35 rotates around the fixed rod 34, so that the stirring plate 35 is reset, so that the stirring plate 35 is in an intermittent stirring state (half a circle stirring, half a circle retraction).

[0042] The intermittent stirring controls the formation and stability of the flocculation body by periodically changing the stirring intensity, which can effectively avoid excessive shearing and prevent the flocculation body from being excessively sheared and broken due to continuous high-intensity stirring, thereby being not conducive to the formation of the flocculation body; the intermittent stirring allows the flocculation body to have sufficient time to grow and coagulate under lower stirring intensity, so as to form a flocculation body with dense structure and large size, which is more easily settled and separated from the liquid, and is more conducive to phosphorus removal from the sewage.

[0043] The scraping mechanism 4 comprises a rotating hole 41 formed in the stirring rod 32 close to one end of the flocculation tank main body 1, a reciprocating screw rod 42 rotatably connected in the rotating hole 41, a roller 43 fixedly connected to the end of the reciprocating screw rod 42 away from the fixed box 31, the roller 43 being located in the stirring track one 12 and closely abutting against the inner wall of the stirring track one 12, a blocking ring 44 fixedly connected to the inner wall of the stirring groove 33, the blocking ring 44 being located outside the reciprocating screw rod 42 and rotatably connected with the reciprocating screw rod 42, a sliding box 45 provided outside the reciprocating screw rod 42, the sliding box 45 being threadedly connected with the reciprocating screw rod 42, and a limiting piece 5 provided on one side of the sliding box 45 and capable of limiting the sliding box 45, the limiting piece 5 comprising a through hole 51 formed in the sliding box 45, and a limiting rod 52 slidably connected in the through hole 51, one end of the limiting rod 52 being fixedly connected with the inner wall of the stirring groove 33, and the other end of the limiting rod 52 being fixedly connected with the outer wall of the fixed box 31.

[0044] When the motor 11 drives the stirring rod 32 to slide along the inner wall of the stirring track one 12 through the stirring rod 2, the roller 43 closely abuts against the inner wall of the stirring track one 12, and when the stirring rod 32 moves, the roller 43 closely abuts against the inner wall of the stirring track one 12 and moves, at this time, the roller 43 rotates at the end of the stirring rod 32, the roller 43 drives the reciprocating screw rod 42 to rotate, and since the limiting rod 52 is located in the through hole 51 formed in the sliding box 45, at this time, the sliding box 45 slides outside the reciprocating screw rod 42, and when the reciprocating screw rod 42 slides back and forth, the scraping piece 6 can clean the surface of the stirring plate 35.

[0045] The scraping piece 6 is arranged at one end of the sliding box 45 away from the limiting rod 52 and can scrape the stirring plate 35. The scraping piece 6 comprises 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 through a support rod 62, the support rod 62 is fixedly connected with a torsional spring 63 on the outer wall, one end of the torsional spring 63 away from the support rod 62 is fixedly connected with a scraper 64, and the scraper 64 is rotationally connected with the support rod 62.

[0046] When the stirring plate 35 is in the vertical state, the scraper 64 is tightly attached to 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 wire rod 42, so that the flocculation body is prevented from adhering to the surface of the stirring plate 35. When the stirring plate 35 changes from the vertical state to the horizontal state, the stirring plate 35 rotates around the fixed rod 34, at this time, the stirring plate 35 lifts the scraper 64, at this time, the scraper 64 rotates around the support rod 62, and the torsional spring 63 is energized. Since the scraper 64 is V-shaped, the scraper 64 is tightly attached to the outer wall of the stirring plate 35, the scraper 64 can always scrape and clean the outer wall of the stirring plate 35, and the scraper 64 can scrape and clean both sides of the stirring plate 35. When the stirring plate 35 changes from the horizontal state to the vertical state, the torsional spring 63 resets to drive the stirring plate 35 to rotate around the fixed rod 34, and the stirring plate 35 is energized by the torsional spring 63 to abut to drive the sewage to be stirred. By adjusting the cycle of intermittent stirring, the mixing of flocculant and suspended particles in sewage can be optimized, the collision probability between particles can be increased, the flocculation effect can be improved, and the amount of flocculant can be reduced by appropriate intermittent stirring strategy, thereby reducing the waste of flocculant caused by excessive stirring and reducing the cost of phosphorus removal.

[0047] Embodiment two

[0048] Please refer to Figures 9-11 The fixed box 31 is provided with an expansion hole 7, a spring 71 is fixedly connected to the inner wall of the fixed box 31, one end of the spring 71 away from the fixed box 31 is fixedly connected with a sleeve 72, the sleeve 72 is located inside the expansion hole 7 and is in sliding connection with the expansion 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, a baffle 74 is fixedly connected to one end of the connecting rod 73 away from the sleeve 72, the baffle 74 is arc-shaped, a plurality of circular holes 75 are formed in 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 rotates inside the flocculation tank main body 1 to collect flocculation bodies through the arc-shaped baffle 74. When the flocculation bodies are small, the flocculation bodies leak out of the circular holes 75 in the baffle 74, at which time the baffle 74 does not displace, the sleeve 72 does not move, and the vertical rod 76 does not displace, at which time the operator can clearly observe that the flocculation bodies have not coagulated. When the flocculation bodies are large, the baffle 74 collects the flocculation bodies when the stirring rod 32 rotates, the flocculation bodies accumulate inside the baffle 74 and cannot penetrate the circular holes 75, at which time the baffle 74 rotates in the sewage with a large resistance, the baffle 74 drives the sleeve 72 to compress the spring 71 through the connecting rod 73, at which time the sleeve 72 displaces, and the vertical rod 76 displaces to remind the operator that the flocculation in the flocculation tank main body 1 is complete, facilitating the next step.
