DETAILED DESCRIPTION

[0052] 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 skilled in the art without creative work fall within the scope of protection of the present application.

[0053] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0054] Embodiment one, please refer to Figures 1 to 12The utility model provides an integrated oil removal device for oily sewage, comprising a treatment box 1 and a plurality of supporting legs fixed to the bottom of the treatment box 1, further comprising a gas float mechanism installed in the treatment box 1, which floats and collects impurities and oil in the sewage to the water surface through the gas float mechanism.

[0055] A feed pipe 5 is fixed to the bottom of the treatment box 1, the input end of the feed pipe 5 is fixed with a suction pipe 502 in communication therewith, and the output end of the feed pipe 5 is fixed with a second discharge pipe 501 in communication therewith, and the second discharge pipe 501 communicates with the bottom of the treatment box 1.

[0056] A separation mechanism is installed at the bottom of the treatment box 1 and connected with the gas float mechanism.

[0057] In the embodiment of the utility model, the suction pipe 502 communicates with the sewage storage device, the feed pipe 5 is driven to work by being electrified, and the sewage is sucked into the feed pipe 5 through the suction pipe 502 and then discharged into the treatment box 1 through the second discharge pipe 501, the impurities and oil in the sewage in the treatment box 1 are floated to the water surface by the gas float mechanism, and the impurities and oil floated to the top are separated and transported to the separation mechanism, and the oil and impurities in the separation mechanism are separated separately; this process ensures that the solid particles and oil in the sewage are effectively removed, so that the sewage is preliminarily purified.

[0058] Subsequently, the preliminarily purified sewage will enter a further treatment stage, which may include biological treatment, chemical treatment or physical filtration method, etc. to further reduce the harmful substance content in the sewage, finally, the water treated by the utility model will meet the relevant discharge standard, ensuring the safety and cleanliness of the environment.

[0059] The gas float mechanism comprises a first discharge pipe 3 concentrically arranged with the treatment box 1, the first discharge pipe 3 penetrates the bottom of the treatment box 1, the treatment box 1 is fixed with a converging baffle 2 arranged in a snail shape, and the first discharge pipe 3 is provided with a discharge port 301 matched with the converging baffle 2.

[0060] The bottom of the discharge port 301 is higher than the bottom of the converging baffle 2, the top of the first discharge pipe 3 is higher than the converging baffle 2, and the top of the first discharge pipe 3 is lower than the top of the treatment box 1.

[0061] The inside bottom of the treatment box 1 is installed with a gas float piece matched with the converging baffle 2.

[0062] In the embodiment of the present invention, the flotation element installed at the bottom of the treatment box 1 of the equipment can cause the sewage to produce a rotational motion. This rotational motion can effectively drive the entire sewage state inside the treatment box 1, making it dynamic. At the same time, the flotation element will generate a large number of tiny bubbles during operation. The buoyancy of the bubbles gradually brings these grease and impurities to the surface of the water.

[0063] Since the sewage inside the treatment box 1 is in a continuous rotation state, the grease and impurities floating to the 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 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.

[0064] It should be noted that, in this embodiment, the sewage treatment process is continuous. Sewage is continuously added to the interior of the device from the bottom of the treatment tank 1. At the same time, in order to maintain a stable liquid level inside the treatment tank 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 tank 1 remains unchanged, thereby providing a stable environment for the entire treatment process.

[0065] 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.

[0066] The air flotation member includes a diverter box 403 fixed to the bottom of the processing box 1 and arranged concentrically with the first discharge pipe 3. A plurality of explosion pipes 4 communicating with the diverter box 403 are fixed equidistantly on the circumference.

[0067] An air pump 401 is fixed to one side of the processing box 1, and an air supply pipe 402 is fixed to the output end of the air pump 401 and connected thereto, and the air supply pipe 402 is fixed to and connected to the diverter box 403;

[0068] The plurality of explosion tubes 4 are all arranged at an angle, and explosion holes are all opened at an angle on the plurality of explosion tubes 4 .

[0069] In the embodiment of the present invention, when the air pump 401 is working, it pumps air into the diversion box 403 through the air supply pipe 402, and then the diversion box 403 diverts the gas into multiple explosion tubes 4, thereby causing the gas to discharge a large number of bubbles through the explosion holes;

[0070] Among them, seeFigure 7 and Figure 10 Since the bubble is formed by air, and since the air vent pipe 4 is in a fixed state, a certain thrust will be generated when the gas is discharged through the air vent hole, and since the air vent pipe 4 is circumferentially arranged, the sewage at the bottom of the treatment tank 1 will be rotated by the thrust of the gas, and the state of the sewage will make the sewage in the entire treatment tank 1 rotate.

[0071] The separation mechanism comprises an oil-water separation tank 6 fixed to the bottom of the treatment tank 1 and arranged concentrically with the treatment tank 1, and a slag discharge element 601 fixed to the feeding pipe 5, wherein the slag discharge element 601 is arranged obliquely, and a slag discharge pipe 602 in communication with the slag discharge element 601 is fixed to the low end of the slag discharge element 601.

[0072] The filter plate 7 is vertically and slidably installed in the oil-water separation tank 6, a solid discharge assembly is installed on the top of the filter plate 7, and an oil liquid extraction element is installed in the oil-water separation tank 6.

[0073] In the embodiment of the present application, the grease, impurities and water discharged through the first discharge pipe 3 are all on the filter plate 7, the impurities are filtered out through the filter plate 7, and the grease and water enter the oil-water separation tank 6, and since the specific gravities of oil and water are different, the oil will float to the surface of the water, and the grease is extracted through the oil liquid extraction element.

[0074] Since the solid impurities are on the filter plate 7, the filter plate 7 will be blocked to a certain extent after a long time of filtering, in order to avoid the blockage, the impurities are cleaned and discharged through the solid discharge assembly, so that the impurities enter the slag discharge element 601, and since the slag discharge element 601 is arranged obliquely, the impurities will move to the slag discharge pipe 602 under the action of the oblique force, and are discharged to a specified position through the slag discharge pipe 602, and the impurities can be collected by placing a collecting element at the bottom of the slag discharge pipe 602.

[0075] The oil liquid extraction element comprises a plurality of guide rods 1004 fixed to the bottom of the oil-water separation tank 6, a discharge pipe 1001 slidably installed on the guide rod 1004, a plurality of floating extraction pipes 1002 circumferentially and equidistantly fixed in the discharge pipe 1001, a plurality of discharge pipes 1001 slidably and sealingly installed on the top of the floating extraction pipe 1002, and a plurality of discharge pipes 1001 fixed and communicated through an oil collecting pipe 1003.

[0076] In the embodiment of the present application, in the present application, the oil collecting pipe 1003 is connected to an extraction device, and a strong extraction force is generated by the extraction device through negative pressure;

[0077] Since the oil-water separation tank 6 is full of water and grease, the oil will naturally float to the liquid surface, and since the floating body 10 is vertically and slidably installed, it will gradually adjust the position according to the change of the liquid surface.

[0078] In the design, the bottom length of the floating extraction pipe 1002 exceeds the bottom of the float 10, which enables the floating extraction pipe 1002 to be below the liquid surface, and since the grease will float to the liquid surface, the floating extraction pipe 1002 mainly extracts the grease;

[0079] Since the sealed sliding connection is adopted between the oil discharge pipe 1001 and the floating extraction pipe 1002, when the liquid level changes and causes the float 10 to move up and down, the partial structure of the oil discharge pipe 1001 and the floating extraction pipe 1002 will be disconnected accordingly.

[0080] The bottom of the floating extraction pipe 1002 is in a sealed arrangement, and the floating extraction pipe 1002 is provided with through holes at equal intervals in the circumference.

[0081] Please refer to Figure 8 In the embodiment of the present application, through the careful design of the structure, when the grease is extracted, the movement direction of the grease is horizontally towards the floating extraction pipe 1002, rather than vertically, which helps to enhance the extraction force of the extraction equipment, thereby significantly improving the extraction efficiency of the grease.

[0082] If the bottom of the floating extraction pipe 1002 is designed as an open structure, the grease can be directly extracted through the opening during the extraction operation, however, when the extraction force becomes very strong, it may cause water and grease to be extracted together, which goes against the basic principle of oil-water separation, because the purpose of oil-water separation is to separate the grease and water, rather than mixing them together.

[0083] The solid discharge assembly comprises four support plates 9 arranged at equal intervals in the circumference, and the four support plates 9 are all fixed to the bottom of the treatment box 1.

[0084] It also comprises a conical member 8 arranged in a conical shape at the top, and the conical member 8 is provided with a support 803 concentrically arranged thereon, and the support 803 and the conical member 8 are fixed through a flow distribution plate 802, and a plurality of slag removing plates 801 are fixed at equal intervals at the edge of the conical member 8.

[0085] The support 803 is installed on the four support plates 9 through a lifting member, and the support 803 also cooperates with a rotating member installed on the support plate 9, and the rotating member cooperates with the lifting member.

[0086] The bottom of the conical member 8 is rotationally connected with the filter plate 7.

[0087] The oil-water separation box 6 is provided with a plurality of through openings 603 at the top.

[0088] In the embodiment of the present application, the oil, impurities and water discharged by the first discharge pipe 3 are dispersed on the filter plate 7 by the taper 8, and the flow splitter 802 reduces the blocking surface when the oil and impurities move, and improves the movement ability of the impurities and oil.

[0089] The lifting member drives the support 803, the flow splitter 802, the taper 8, the slag pushing plate 801 and the filter plate 7 connected with the taper 8 to rise synchronously, and the solid impurities are carried by the filter plate 7 to the position of the through hole 603, and at the same time, the rotating member is in the working state, which drives the support 803, the flow splitter 802, the slag pushing plate 801 and the taper 8 to rotate. Since the filter plate 7 is vertically and slidably installed and connected with the taper 8, the filter plate 7 only rises without rotating. In this process, the fixed impurities are moved by the rotation of the slag pushing plate 801 through the through hole 603.

[0090] The above description can realize the cleaning of the solid impurities on the filter plate 7.

[0091] The lifting member comprises a transmission disc 9014 fixed to the support 803.

[0092] Four transmission shafts 907 are rotatably installed on the side of the support 803 towards the center of the support 803, the cam 909 is coaxially fixed to the end of the transmission shaft 907, the cam 909 is matched with the bottom of the transmission disc 9014, the transmission shaft 907 is connected with the rotating member, the first gear 908 is coaxially fixed to the transmission shaft 907, and the first gear 908 is engaged with the first gear ring 9010 rotatably installed on the support plate 9.

[0093] The support 803 is slidably connected with the first discharge pipe 3.

[0094] In the embodiment of the present application, when the rotating member works, one of the transmission shafts 907 is driven to rotate, the cam 909 is driven to rotate when the transmission shaft 907 rotates, the first gear ring 9010 is driven to rotate by the engagement of the cam 909 and the first gear ring 9010, the remaining four transmission shafts 907 are driven to rotate by the engagement of the first gear ring 9010 and the remaining four first gears 908 when the first gear ring 9010 rotates, and the four transmission shafts 907 are synchronously rotated.

[0095] When the transmission shaft 907 rotates, the cam 909 rotates to drive the transmission disc 9014 and the support 803 to rise when the protruding part of the cam 909 faces the transmission disc 9014, which is the lifting movement; when the cam 909 rotates to the side away from the transmission disc 9014, the support 803 and the transmission disc 9014 are driven to descend and reset by the gravity of the support 803 and the related structure, and then the support 803 and the transmission disc 9014 are reciprocatingly driven to stand up by the continuous rotation of the cam 909, and the standing up movement of the support 803 drives the splitter plate 802, the slag removal plate 801, the conical part 8 and the filter plate 7 to move synchronously.

[0096] The protruding part of the cam 909 is rotatably installed with a roller, which can reduce the friction during cooperation.

[0097] The rotating part comprises a limiting cylinder 901 which is vertically and rotatably installed on the support plate 9 towards the side of the center of the support 803, a limiting rod 902 is slidably installed in the limiting cylinder 901, a second gear 9011 is coaxially fixed on the bottom of the limiting rod 902, and the second gear 9011 is rotatably connected with the transmission disc 9014.

[0098] A transmission rod 905 is also rotatably installed on the support plate 9, and the transmission rod 905 is connected with the limiting cylinder 901 through a bevel gear set 903.

[0099] A motor 9013 is also fixed on the support plate 9, an output shaft of the motor 9013 is connected with the transmission rod 905 through a first transmission chain 904, and the transmission rod 905 is also connected with the transmission shaft 907 through a second transmission chain 906.

[0100] A second gear ring 9012 is coaxially fixed on the motor 9013, and the second gear ring 9012 is engaged with the second gear 9011.

[0101] In the embodiment of the application, a transmission groove is formed in the limiting cylinder 901, and a transmission strip fixed on the limiting rod 902 is slidably matched with the transmission groove, so that the limiting rod 902 can be driven to rotate when the limiting cylinder 901 rotates through the cooperation of the transmission groove and the transmission strip, and the limiting rod 902 can slide axially along the limiting cylinder 901.

[0102] When the motor 9013 works, the output shaft thereof drives the transmission rod 905 to rotate through the first transmission chain 904, and 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.

[0103] 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 the transmission disc 9014 and the support 803 are driven to rotate through the meshing of the second gear ring 9012 when the second gear 9011 rotates, and the shunt plate 802, the slag removal plate 801 and the conical part 8 are synchronously driven to rotate when the support 803 rotates.

[0104] It should be noted that the bevel gear set 903 includes two mutually meshing bevel gears, and the two bevel gears are coaxially fixed with the transmission rod 905 and the limiting cylinder 901, respectively.
