Industrial sewage treatment device

Technical Field

The invention relates to the technical field of sewage treatment, and in particular to an industrial sewage treatment device.

Background Art

Steel rolling wastewater is the wastewater generated when the hot rolling workshop of a steel plant uses water to cool the rolls and wash away the oxidized iron scale when hot rolling steel ingots into various steel products. It is a common industrial wastewater.

The main pollutants in steel rolling wastewater are large amounts of iron oxide scale and lubricating oils of different particle sizes. In the process of industrial wastewater treatment, flotation technology is usually used to treat the oil in industrial wastewater.

The flotation machine is a water treatment equipment that generates a large number of fine bubbles in the water by a dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby realizing solid-liquid separation, thereby treating the sewage. When the sewage is treated by the flotation process, since the oil and suspended particles float on the water surface with the bubbles, the scum floating on the water surface needs to be removed. In the prior art, a scraper plate is usually used to scrape the scum on the upper liquid surface of the scum area. The scraping area of the scum is small, and the scraper plate cannot be moved, and the scraper plate is difficult to adjust according to the liquid level, resulting in poor effect of removing the scum.

DETAILED DESCRIPTION

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.

Please refer to Figures 1 to 8. The present invention provides a technical solution: an industrial sewage treatment device, including a treatment pool 1, wherein a partition 2 is fixedly connected to the inside of the treatment pool 1, and a gap is formed between the bottom of the partition 2 and the bottom of the inner wall of the treatment pool 1, and an air injection hood 3 for ejecting bubbles is arranged on the right side of the partition 2 inside the treatment pool 1, and a slag removal mechanism 5 for removing scum is arranged outside the treatment pool 1, and the slag removal mechanism 5 includes a bracket assembly 51 arranged outside the treatment pool 1, and a slag scooping assembly 52 for scooping scum is arranged inside the bracket assembly 51, and a driving part 6 for driving the bracket assembly 51 to reciprocate is arranged at the front and rear ends of the treatment pool 1, and the slag scooping assembly 52 includes a slag discharge pipe 521 arranged above the treatment pool 1, and a plurality of arc seats 524 are arranged outside the slag discharge pipe 521, and the plurality of arc seats 524 are arranged on the outside of the slag discharge pipe 521. A slag scooping cover 522 is fixedly connected between the arc seats 524, and a plurality of water leakage holes 523 are provided inside the slag scooping cover 522. An inlet groove 525 is provided on the top of the slag discharge pipe 521. A transmission part 7 for driving the arc seat 524 to rotate is provided at the rear end of the arc seat 524. The transmission part 7 includes a connecting rod 71 fixedly connected to the rear end of the arc seat 524, and a first gear 72 is fixedly connected to the rear end of the connecting rod 71. Two baffles 73 are fixedly connected to the top of the rear end of the treatment pool 1, and a tooth plate 74 is provided between the two baffles 73. The tooth plate 74 is meshed with the first gear 72. The arc seat 524 and the slag scooping cover 522 can rotate around the slag discharge pipe 521 as a whole. A plurality of nozzles are fixedly installed on the top of the jet hood 3, and a gas inlet pipe is plugged into the rear end of the jet hood 3, and the gas inlet pipe runs through the treatment pool 1.

By adopting the above technical scheme, when in use, the steel-rolling wastewater is input from the fixedly plugged pipe on the left side of the treatment tank 1 to the treatment tank 1 on the left side of the partition 2, and a flocculant is added here to facilitate the conversion of fine impurities in the water into flocs. Then the sewage enters the treatment tank 1 on the right side of the partition 2, and the external gas is input into the gas inlet pipe, so that the gas enters the jet hood 3, so that a large number of tiny bubbles are sprayed out from the nozzle, so that the bubbles attach to the oil and impurities in the water, so that the bubbles can float on the water surface with the oil and impurities in the water, and the industrial wastewater can be treated.

When it is necessary to remove the scum floating on the water surface, the driving unit 6 moves back and forth with the bracket assembly 51, so that part of the scum scooping assembly 52 can move with the movement of the bracket assembly 51, so as to salvage the scum on the water surface in different areas. The left and right sides of the tooth plate 74 are in contact with the side of the two baffles 73 that are close to each other, so under the limiting effect of the two baffles 73, the tooth plate 74 can be prevented from moving in the left and right directions. When the driving unit 6 moves back and forth with the bracket assembly 51 and the scum scooping assembly 52, the arc seat 524 moves with the slag discharge pipe 521, so the connecting rod 71 and the first gear 72 can move with the arc seat 524. Since the tooth plate 74 is meshed with the first gear 72, when the first gear 72 moves, Under the action of the tooth plate 74, the first gear 72 can rotate with the connecting rod 71, the arc seat 524 and the slag scoop cover 522. Since the multiple slag scoop covers 522 rotate continuously, the slag scoop covers 522 can continuously salvage slag on the water surface. When the slag scoop cover 522 with salvaged slag rotates to the top of the entry groove 525, under the action of gravity, the slag salvaged by the slag scoop cover 522 falls into the interior of the slag discharge pipe 521. The front end bottom of the slag discharge pipe 521 is fixedly connected with an outlet pipe, and the bottom of the outlet pipe is provided with a collecting bin for collecting slag. The slag entering the slag discharge pipe 521 can enter the interior of the collecting bin through the outlet pipe, and in conjunction with the movement of the slag scoop assembly 52, slag on the water surface of different areas can be salvaged.

It should be noted that during the slag removal process, some water may be removed. The water leakage hole 523 can filter out some of the water and return the removed water to the treatment tank 1, thereby avoiding a large amount of water being discharged during the slag removal process and causing a waste of water resources.

The bracket assembly 51 includes a fixed seat 511 fixedly connected to the front and rear ends of the treatment pool 1, the fixed seat 511 is slidably connected to a through plate 512 inside, and a connecting frame 513 is slidably connected to the top of the through plate 512. The outer wall of the slag discharge pipe 521 is fixedly plugged with the connecting frame 513, and the interior of the slag discharge pipe 521 is hollow. The interior of the through plate 512 is fixedly connected to an electric telescopic rod 514, and the output shaft of the electric telescopic rod 514 is fixedly connected to the connecting frame 513. The top of the tooth plate 74 is fixedly connected to a connecting plate 75, and the connecting frame 513 at the rear end is slidably connected to the connecting plate 75, so that the tooth plate 74 and the connecting plate 75 are raised and lowered with the connecting frame 513 to ensure that the tooth plate 74 remains in mesh with the first gear 72.

By adopting the above technical solution, the driving part 6 includes a servo motor 61 fixedly connected to the left side of the fixing seat 511, the output shaft of the servo motor 61 passes through the fixing seat 511 and is fixedly connected with a screw rod 62, the right side of the screw rod 62 is rotatably connected to the fixing seat 511, the outer wall of the screw rod 62 is threadedly connected to the through plate 512, and the output shaft of the servo motor 61 drives the screw rod 62 to rotate back and forth, so that the through plate 512 drives the connecting frame 513 and the slag scooping assembly 52 to move back and forth, and the output shaft of the electric telescopic rod 514 is extended and retracted, so that the connecting frame 513 drives the slag discharge pipe 521, the slag scooping cover 522 and the arc seat 524 to move up and down, and the height of the slag discharge pipe 521, the slag scooping cover 522 and the arc seat 524 can be adjusted according to the different water surface heights. The degree can be adjusted so that the bottom area of the slag scoop cover 522 can just salvage the scum on the water surface. On the one hand, it can be avoided that when the water surface is low, the slag scoop cover 522 cannot contact the scum and cannot be salvaged. On the other hand, when the water surface is high, when one of the slag scoop covers 522 is rotated to a vertically downward state, most of the slag scoop cover 522 is prevented from being inserted below the water surface, thereby avoiding a large amount of water being scooped out during the slag scooping process and causing water waste. Moreover, since the slag scoop cover 522 is continuously scooping scum, a large amount of scum will be stuck on the surface of the slag scoop cover 522, which can avoid that most of the slag scoop cover 522 is inserted below the water surface, thereby preventing the scum on the surface of the slag scoop cover 522 from returning to the water and affecting the effect of water treatment.

Slag grooves 526 are provided on both sides of the slag scooping cover 522 , and the tooth plate 74 is located above the first gear 72 .

By adopting the above technical solution, the design of the slag groove 526 is convenient for the slag to be fished out to be inside the slag groove 526. Since the tooth plate 74 is above the first gear 72, when the driving part 6 moves the bracket assembly 51 and the slag fishing assembly 52 to the left, the arc seat 524 and the slag fishing cover 522 rotate in the clockwise direction. When the driving part 6 moves the bracket assembly 51 and the slag fishing assembly 52 to the right, the arc seat 524 and the slag fishing cover 522 rotate in the counterclockwise direction, ensuring that the slag fishing cover 522 always fishes out the slag from bottom to top, thereby achieving a good slag fishing effect and improving the slag fishing efficiency.

The inner diameter of the slag discharge pipe 521 gradually increases from the back to the front, and the arc seat 524 is inclined near the slag scoop cover 522 .

By adopting the above technical solution, since the inner diameter of the slag discharge pipe 521 gradually increases from the back to the front, the inside of the slag discharge pipe 521 is inclined, which makes it easier for the slag to enter the outlet pipe, thereby facilitating the discharge of the slag and further improving the efficiency of slag removal. Since the arc seat 524 is inclined close to the slag scooping cover 522, the slag scooped out by the slag scooping cover 522 can enter between adjacent arc seats 524, thereby facilitating the slag to enter the inside of the slag discharge pipe 521.

A blowing assembly 8 is arranged above the fixed seat 511, and the blowing assembly 8 includes a mounting cover 81 fixedly connected between two connecting frames 513, a corrugated airbag 82 is fixedly connected to the top of the inner wall of the mounting cover 81, a limiting frame 83 is fixedly connected to the bottom of the corrugated airbag 82, and both sides of the bottom of the limiting frame 83 are inclined, a side of the slag scooping cover 522 away from the slag discharge pipe 521 is fixedly connected to an extrusion plate 84, and a side of the extrusion plate 84 away from the slag scooping cover 522 is rotatably connected to a circular shaft 85, and an air outlet pipe 86 is fixedly plugged at the top rear end of the corrugated airbag 82, and one end of the air outlet pipe 86 away from the corrugated airbag 82 is fixedly plugged to the rear end of the slag discharge pipe 521.

By adopting the above technical solution, as the slag scooping cover 522 continuously rotates while scooping slag, the extrusion plate 84 and the circular shaft 85 rotate. When the outer wall of the circular shaft 85 contacts the inclined surface of the limiting frame 83 and continues to rotate, the limiting frame 83 is squeezed by the circular shaft 85 and moves upward, thereby compressing the corrugated airbag 82, making it easier for the gas inside the corrugated airbag 82 to enter the rear end of the slag discharge pipe 521 from the outlet pipe 86. At this time, an airflow is generated from the back to the front inside the slag discharge pipe 521. Under the action of the airflow, the slag inside the slag discharge pipe 521 is easy to enter the outlet pipe, which facilitates the discharge of the slag, thereby further improving the slag removal efficiency. The setting of the circular shaft 85 makes it easy to reduce the friction between the outer wall of the circular shaft 85 and the limiting frame 83.

The blowing assembly 8 also includes a fixed cover 87 fixedly connected to the front end of the slag discharge pipe 521, and an air inlet pipe 88 is fixedly inserted at the top front end of the corrugated airbag 82, and the end of the air inlet pipe 88 away from the corrugated airbag 82 is fixedly inserted into the fixed cover 87, and the inside of the slag discharge pipe 521 is rotatably connected to a round rod 89, and the outer wall of the round rod 89 is fixedly connected to a plurality of scrapers 810, and the front end of the round rod 89 passes through the slag discharge pipe 521 and is fixedly connected to a plurality of wind shields 811, and the wind shields 811 are located inside the fixed cover 87, and a small tube 812 is fixedly inserted at the bottom of the fixed cover 87 to facilitate airflow from blowing to the area away from the round rod 89 from the wind shield 811, and the plurality of scrapers 810 are staggered and fixed to the outer wall of the round rod 89, and the end of the scraper 810 away from the round rod 89 is in contact with the inner wall of the slag discharge pipe 521.

By adopting the above technical solution, when the outer wall of the circular shaft 85 is not in contact with the limiting frame 83, the corrugated airbag 82 is easy to stretch under the action of the elastic force of the corrugated airbag 82 itself and the gravity of the limiting frame 83 itself, so that the external gas enters the corrugated airbag 82 through the air inlet pipe 88. At this time, since the end of the air inlet pipe 88 away from the corrugated airbag 82 is in an air-intake state, a negative pressure is generated inside the fixed cover 87, causing the gas to enter the fixed cover 87 from the small tube 812. At this time, under the action of the airflow, it is easy for the windshield plate 811 to rotate with the round rod 89, so that the scraper 810 can scrape the inner wall of the slag discharge pipe 521, and cooperate with the inner diameter of the slag discharge pipe 521 to gradually increase from back to front, which can facilitate the movement of slag from back to front, thereby further facilitating the discharge of slag, thereby further improving the efficiency of slag removal.

It is worth noting that check valves are installed inside the air inlet pipe 88 and the air outlet pipe 86. The check valve is a mature existing technology, and its installation method and principle are not elaborated in detail. Under the action of the check valve inside the air inlet pipe 88, the air inside the air inlet pipe 88 can only flow along the air inlet pipe 88 toward the corrugated airbag 82, and under the action of the check valve inside the air outlet pipe 86, the air inside the air outlet pipe 86 can only flow along the air outlet pipe 86 toward the slag discharge pipe 521.

Specifically, as shown in Figures 1, 2, 3, 9 and 10, a flocculation component 9 is provided on the left side of the partition 2, and the flocculation component 9 includes a small plate 91 fixedly connected to the top of the treatment tank 1, a stirring frame 10 is provided on the left side of the partition 2, and a driving part 4 for driving the stirring frame 10 to rotate is provided above the small plate 91, the top area of the stirring frame 10 is hollow inside, and discharge pipes 92 are fixedly inserted on both sides of the top of the stirring frame 10, and an intake cover 93 is fixedly inserted on the top of the stirring frame 10, and a silo frame 94 is fixedly connected to the top of the small plate 91. A circular hole 95 is provided at the bottom, the receiving cover 93 is located below the circular hole 95, the inner bottom end of the discharge pipe 92 is inclined, a plurality of discharge holes 96 are provided at the bottom of the discharge pipe 92, the inner diameter of the receiving cover 93 is larger than the inner diameter of the circular hole 95, the stirring frame 10 is rotatably connected to the small plate 91, the driving part 4 includes a second motor 41 fixedly connected to the middle part of the top of the small plate 91, the output shaft of the second motor 41 is fixedly connected to the second gear 42, the driving part 4 also includes a third gear 43 fixedly connected to the top of the outer wall of the stirring frame 10, and the second gear 42 is meshed with the third gear 43.

By adopting the above technical solution, flocculant is added to the interior of the silo rack 94 during use, and the flocculant inside the silo rack 94 enters into the interior of the receiving cover 93 from the circular hole 95, and enters into the hollow space at the top of the stirring rack 10 from the receiving cover 93, and then the flocculant enters into the discharge pipe 92, and reaches multiple discharge holes 96 by utilizing the inner bottom end inclination of the discharge pipe 92, and finally falls into the water from the discharge holes 96, and the output shaft of the second motor 41 rotates, so that the second gear 42 rotates with the third gear 43, thereby facilitating the rotation of the stirring rack 10 to facilitate mixing of the flocculant and water, and the stirring rack 10 can rotate with the discharge pipe 92, so that the flocculant can be put into the water more evenly, and the mixing effect of the flocculant and water by the stirring rack 10 can make the mixing effect of the flocculant and water good.

Working principle: When in use, the steel-rolling wastewater enters the treatment tank 1 from the fixedly plugged pipe on the left side of the treatment tank 1 to the left side of the partition 2. The flocculant inside the silo frame 94 enters the inside of the collection cover 93 from the circular hole 95, and enters the hollow part of the top of the stirring frame 10 from the collection cover 93. Then the flocculant enters the discharge pipe 92, and reaches the multiple discharge holes 96 by the inner bottom end of the discharge pipe 92, and finally falls into the water from the discharge hole 96. The stirring frame 10 mixes the flocculant and water, which is convenient for mixing the water and the flocculant. The driving part 6 carries the bracket assembly 51. When the slag scooping assembly 52 reciprocates, under the action of the first gear 72 and the tooth plate 74, the connecting rod 71, the arc seat 524 and the slag scooping cover 522 are easy to rotate. Since the multiple slag scooping covers 522 are constantly rotating, the slag scooping covers 522 can continuously salvage the floating slag on the water surface, and with the movement of the slag scooping assembly 52, the floating slag on the water surface of different areas can be salvaged. The output shaft of the electric telescopic rod 514 is telescopic, which can make the connecting frame 513 move up and down with the slag discharge pipe 521, the slag scooping cover 522 and the arc seat 524, and the slag discharge can be carried out according to the different water surface heights. The height of the pipe 521, the slag scooping cover 522 and the arc seat 524 can be adjusted. As the slag scooping cover 522 rotates continuously when scooping slag, the extrusion plate 84 and the round shaft 85 rotate, and the limiting frame 83 is squeezed by the round shaft 85 and moves upward, so that the corrugated airbag 82 is compressed, so that the gas inside the corrugated airbag 82 enters the rear end of the slag discharge pipe 521 from the outlet pipe 86. At this time, the inside of the slag discharge pipe 521 generates airflow from back to front. Under the action of the airflow, the floating slag inside the slag discharge pipe 521 enters the outlet pipe, which is convenient for the discharge of the floating slag. When the outer surface of the round shaft 85 is When the wall is not in contact with the limiting frame 83, the elastic force of the corrugated airbag 82 itself and the gravity of the limiting frame 83 itself facilitate the expansion of the corrugated airbag 82, so that the external gas enters the corrugated airbag 82 through the air inlet pipe 88, causing the gas to enter the fixed cover 87 from the small tube 812.
