DETAILED DESCRIPTION

[0029] 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.

[0030] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] For example, see Figures 1 to 12 , an integrated flotation oil removal device for oily wastewater, comprising a treatment box 1 and a plurality of legs fixed to the bottom of the treatment box 1, and also comprising an air flotation mechanism, the air flotation mechanism being installed in the treatment box 1, through which impurities and grease in the wastewater are floated to the water surface and collected; A feed pipe 5, the feed pipe 5 is fixed to the bottom of the processing box 1, the input end of the feed pipe 5 is fixed with a suction pipe 502 connected thereto, the output end of the feed pipe 5 is fixed with a No. 2 discharge pipe 501 connected thereto, and the No. 2 discharge pipe 501 is connected to the bottom of the processing box 1; A separation mechanism is installed at the bottom of the processing box 1 and connected to the air flotation mechanism.

[0032] In the embodiment of the present invention, the suction pipe 502 is connected to the sewage storage device, and the feed pipe 5 is driven to work by electrifying the feed pipe 5. When the feed pipe 5 is working, the sewage is sucked in through the suction pipe 502 and then discharged into the treatment box 1 through the second discharge pipe 501. The sewage in the treatment box 1 floats impurities and grease in the sewage to the water surface through the air flotation mechanism, and the impurities and grease floating to the top are separated and transported to the separation mechanism, and the grease and impurities in the sewage are separated separately through the separation mechanism; this process ensures that the solid particles and grease in the sewage are effectively removed, so that the sewage is preliminarily purified; Subsequently, the initially purified sewage will enter a further treatment stage, which may include biological treatment, chemical treatment or physical filtration to further reduce the content of harmful substances in the sewage. Ultimately, the water treated by the present invention will meet the relevant emission standards to ensure the safety and cleanliness of the environment.

[0033] The air flotation mechanism includes a No. 1 discharge pipe 3 arranged concentrically with the processing box 1, the No. 1 discharge pipe 3 passes through the bottom of the processing box 1, a gathering baffle 2 arranged in a spiral line is fixed in the processing box 1, and a discharge port 301 cooperating with the gathering baffle 2 is opened on the No. 1 discharge pipe 3; The bottom of the discharge port 301 is higher than the bottom of the gathering baffle 2, the top of the No. 1 discharge pipe 3 is higher than the gathering baffle 2, and the top of the No. 1 discharge pipe 3 is lower than the top of the processing box 1; An air flotation component is installed at the bottom of the inner side of the processing box 1 , and the air flotation component cooperates with the gathering baffle 2 .

[0034] In the embodiment of the present invention, the air flotation element installed at the bottom of the equipment treatment box 1 can make the sewage produce a rotational motion. This rotational motion can effectively drive the entire sewage state inside the treatment box 1 to be in a dynamic state. At the same time, the air flotation element will generate a large number of tiny bubbles during operation, and the buoyancy of the bubbles will gradually bring these grease and impurities to the surface of the water. Since the sewage inside the treatment box 1 is in a continuous rotating state, the grease and impurities floating to the water surface will also keep rotating. In this dynamic process, the guiding role of the gathering baffle 2 is particularly important. It will guide the grease and impurities floating to the water surface to move along a specific path toward the discharge port 301 of the first discharge pipe 3 and enter the first discharge pipe 3. This process ensures that the grease and impurities can be guided to the next treatment stage in an orderly manner. It should be particularly pointed out that in this embodiment, the process of treating sewage is continuous, and sewage is continuously added to the inside of the device from the bottom of the treatment box 1. At the same time, in order to maintain the stability of the liquid level inside the treatment box 1, an equal amount of sewage is discharged through the discharge port 301 of the first discharge pipe 3. This dynamic balance ensures that the liquid level inside the treatment box 1 remains unchanged, thereby providing a stable environment for the entire treatment process. When the grease and impurities partially enter the No. 1 discharge pipe 3 through the discharge port 301, they will be directly guided to the separation mechanism for further treatment. In this process, a certain amount of water will be mixed with the residue impurities and grease, and the grease and impurities are not completely separated. This treatment method ensures the efficiency and practicality of the entire sewage treatment process.

[0035] The air flotation member includes a diverter box 403 fixed to the bottom of the treatment box 1 and arranged concentrically with the first discharge pipe 3, and a plurality of explosion pipes 4 connected to the diverter box 403 are fixed equidistantly on the circumference thereof; An air pump 401 is fixed to one side of the processing box 1, and an air supply pipe 402 connected to the output end of the air pump 401 is fixed, and the air supply pipe 402 is fixed and connected to the diverter box 403; The plurality of gas explosion pipes 4 are all arranged at an angle, and the plurality of gas explosion pipes 4 are all provided with gas explosion holes at an angle.

[0036] In the embodiment of the present invention, when the air pump 401 is working, the air is pumped into the diverter box 403 through the air supply pipe 402, and then the gas is diverted into the multiple explosion tubes 4 through the diverter box 403, so that the gas is discharged through the explosion holes. A large number of bubbles; Among them, see Figure 7 and Fig.10 Since the bubbles are formed as air and the explosion pipe 4 is in a fixed state, a certain thrust will be generated when the gas is discharged through the explosion hole. Since the explosion pipe 4 is arranged in a circle, the thrust of the gas causes the sewage at the bottom of the treatment box 1 to rotate, and the state of the sewage will cause the sewage in the entire treatment box 1 to rotate.

[0037] The separation mechanism comprises an oil-water separation box 6 fixed to the bottom of the processing box 1 and arranged concentrically with the processing box 1, a slag discharge piece 601 is fixed on the feeding pipe 5, the slag discharge piece 601 is arranged obliquely, and a slag discharge pipe 602 connected thereto is fixed at the lower end of the slag discharge piece 601; A filter plate 7 is vertically and slidably installed in the oil-water separation box 6 , a solid discharge component is installed on the top of the filter plate 7 , and an oil extraction component is installed in the oil-water separation box 6 .

[0038] In the embodiment of the present invention, the grease, impurities and water discharged through the No. 1 discharge pipe 3 are all on the filter plate 7, and the solid impurities are filtered out through the filter plate 7, while the grease and water enter the oil-water separation box 6. Since the seals of oil and water are different, the oil will float to the surface of the water, so that the grease can be extracted through the oil extraction member; Among them, since the solid impurities are on the filter plate 7, after a long period of filtration, the filter plate 7 will be blocked to a certain extent. In order to avoid blockage, the impurities are cleaned and discharged through the solid discharge component, so that the impurities enter the slag discharge part 601. Since the slag discharge part 601 is inclined, the impurities will move into the slag discharge pipe 602 under the driving force of the inclined force, and will be guided and discharged to the designated position through the slag discharge pipe 602. The impurities can be collected by placing a collecting part at the bottom of the slag discharge pipe 602.

[0039] The oil extraction component includes a plurality of guide rods 1004 fixed to the bottom of the oil-water separation box 6, an oil drain pipe 1001 is slidably mounted on the guide rods 1004, a plurality of floating extraction pipes 1002 are equidistantly fixed on the inner circumference of the oil drain pipe 1001, a plurality of oil drain pipes 1001 are sealed and slidably mounted on the top of the floating extraction pipe 1002, and the plurality of oil drain pipes 1001 are fixed and connected via an oil collecting pipe 1003.

[0040] In the embodiment of the present invention, in the present invention, the oil collecting pipe 1003 is connected to the extraction device, and negative pressure is generated by the extraction device, thereby forming a strong extraction force; Since the oil-water separation box 6 is filled with water and grease, it naturally floats above the liquid surface, and since the float 10 is installed vertically and slidably, it will gradually adjust its position according to the change of the liquid surface; In the design, the bottom length of the floating extraction pipe 1002 exceeds the bottom of the float 10, so that the floating extraction pipe 1002 can be below the liquid surface. Since grease will float above the liquid surface, the floating extraction pipe 1002 mainly extracts grease. Since the oil discharge pipe 1001 and the floating extraction pipe 1002 are connected by sealed sliding, when the liquid level changes and causes the float 10 to move up and down, parts of the oil discharge pipe 1001 and the floating extraction pipe 1002 will be detached accordingly.

[0041] The bottom of the floating extraction pipe 1002 is sealed, and through holes are equidistantly opened on the circumference of the floating extraction pipe 1002 .

[0042] See also Figure 8 In the embodiment of the present invention, through the carefully designed structural setting, when the grease is extracted, the movement direction of the grease is horizontally toward the floating extraction tube 1002, rather than vertically. This horizontal movement helps to enhance the extraction force of the extraction device, thereby significantly improving the extraction efficiency of the grease; If the bottom of the floating extraction pipe 1002 is designed as an open structure, the grease can be directly extracted through this opening during the extraction operation. However, when the extraction force becomes very strong, water and grease may be extracted together. This violates the basic principle of oil-water separation, because the purpose of oil-water separation is to separate grease and water, not to mix them together.

[0043] The solid discharge assembly includes four support plates 9 equidistantly arranged in a circle, and the four support plates 9 are all fixed to the bottom of the processing box 1; It also includes a conical member 8 with a conical top, a bracket 803 is coaxially arranged on the conical member 8, the bracket 803 and the conical member 8 are fixed by a splitter plate 802, and a plurality of slag removal plates 801 are fixed at equal distances on the edge of the conical member 8; The bracket 803 is mounted on four support plates 9 via a lifting member, and the bracket 803 also cooperates with a rotating member mounted on the support plate 9, and the rotating member cooperates with the lifting member; The bottom of the cone 8 is rotatably connected to the filter plate 7; The top of the oil-water separation box 6 is provided with a plurality of openings 603 .

[0044] In the embodiment of the present invention, the grease, impurities and water discharged from the No. 1 discharge pipe 3 are dispersed onto the filter plate 7 through the conical member 8 to make them uniform, and the diverter plate 802 can reduce the blocking surface when the grease and impurities move, thereby improving the movement ability of the impurities and grease; The lifting member drives the bracket 803, the diverter plate 802, the cone 8, the slag plate 801, and the filter plate 7 connected to the cone 8 to rise synchronously, and the filter plate 7 carries the solid impurities to the position of the through-port 603. At the same time, the rotating member is also in working state, which drives the bracket 803, the diverter plate 802, the slag plate 801, and the cone 8 to rotate. Since the filter plate 7 is vertically slidably installed and is connected to the cone 8 to rotate, the filter plate 7 does not rotate but only rises. In this process, the rotation of the slag plate 801 moves the fixed impurities through the through-port 603 and moves into the through-port 603. Through the above description, the solid impurities on the filter plate 7 can be cleaned.

[0045] The lifting member includes a transmission plate 9014 fixed to the bracket 803; A transmission shaft 907 is rotatably mounted on one side of the four support plates 9 facing the center of the bracket 803, a cam 909 is coaxially fixed to the end of the transmission shaft 907, the cam 909 cooperates with the bottom of the transmission plate 9014, the transmission shaft 907 is connected to the rotating member, a No. 1 gear 908 is coaxially fixed on the transmission shaft 907, and the No. 1 gear 908 is meshed with a No. 1 gear ring 9010 rotatably mounted on the support plate 9; The bracket 803 is slidably connected to the No. 1 discharge pipe 3 .

[0046] In the embodiment of the present invention, when the rotating member is working, it drives one of the transmission shafts 907 to rotate, and when the transmission shaft 907 rotates, it drives the cam 909 to rotate, so that the first gear ring 9010 is driven to rotate through the meshing of the cam 909 and the first gear ring 9010, and when the first gear ring 9010 rotates, it drives the remaining four transmission shafts 907 to rotate through the meshing with the remaining four first gears 908, thereby making the four transmission shafts 907 rotate synchronously; When the transmission shaft 907 rotates, the cam 909 is driven to rotate, so that when the protruding part of the cam 909 faces the transmission disk 9014, the transmission disk 9014 and the bracket 803 are driven to rise. This process is a lifting movement. When the cam 909 is disengaged and rotates to the side away from the transmission disk 9014, the bracket 803 and the transmission disk 9014 are driven to fall and reset by the gravity of the bracket 803 and related structures, and then the bracket 803 and the transmission disk 9014 are driven to reciprocate vertically through the continuous rotation of the cam 909. The vertical movement of the bracket 803 drives the diverter plate 802, the slag plate 801, the cone 8, and the filter plate 7 to move synchronously. The protruding portion of the cam 909 can rotatably mount a roller, and the mounting roller can reduce friction during mating.

[0047] The rotating member includes a limiting cylinder 901 which is vertically and rotatably mounted on the support plate 9 on the side facing the center of the bracket 803, a limiting rod 902 is slidably mounted in the limiting cylinder 901, a second gear 9011 is coaxially fixed to the bottom of the limiting rod 902, and the second gear 9011 is rotatably connected to the transmission plate 9014; A transmission rod 905 is also rotatably mounted on the support plate 9, and the transmission rod 905 is connected to the limiting cylinder 901 via a bevel gear set 903; A motor 9013 is also fixed on the support plate 9, and the output shaft of the motor 9013 is connected to the transmission rod 905 through a No. 1 transmission chain 904, and the transmission rod 905 is also connected to the transmission shaft 907 through a No. 2 transmission chain 906; A second gear ring 9012 is coaxially fixed to the motor 9013 , and the second gear ring 9012 is meshed with the second gear 9011 .

[0048] In the embodiment of the present invention, a transmission groove is provided inside the limiting cylinder 901, and the transmission groove is slidably matched with a transmission bar fixed on the limiting rod 902, so that when the limiting cylinder 901 rotates, the limiting rod 902 can be driven to rotate through the cooperation between the transmission groove and the transmission bar, and the limiting rod 902 can slide axially along the limiting cylinder 901; When the motor 9013 is working, its output shaft drives the transmission rod 905 to rotate through the first transmission chain 904. When the transmission rod 905 rotates, the limiting cylinder 901 is driven to rotate through the bevel gear set 903, and the transmission shaft 907 is driven to rotate through the second transmission chain 906. When the limiting cylinder 901 rotates, the limiting cylinder 901 and the second gear 9011 are driven to rotate through the cooperation of the transmission groove and the transmission bar, so that when the second gear 9011 rotates, the transmission plate 9014 and the bracket 803 are driven to rotate through the engagement with the second gear ring 9012, and when the bracket 803 rotates, the diverter plate 802, the slag plate 801 and the cone member 8 are driven to rotate synchronously; It should be noted that the bevel gear set 903 includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the transmission rod 905 and the limiting cylinder 901 respectively.

[0049] Discharge pipes are fixed on the tops of the treatment box 1 and the oil-water separation box 6, and ball valves are installed at the discharge ends.

[0050] In an embodiment of the present invention, at the end of the sewage treatment, there will be a certain amount of treated water in the treatment box 1 and the oil-water separation box 6, which will be discharged through the discharge pipe. The discharge pipe of the oil-water separation box 6 is responsible for the water discharge during sewage treatment, and the ball valve can control the opening and closing of the discharge pipe.
