DETAILED DESCRIPTION

[0043] 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.

[0044] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: an intelligent sewage treatment and recycled water resource utilization device, comprising a drum 2 made of stainless steel material, both sides of the drum 2 are provided with connecting members 1, and the drum 2 is movably connected between the two connecting members 1, wherein, as Figure 3 As shown, the connecting member 1 includes a bearing 101, and the two ends of the drum 2 are respectively fixed to the inner rings of the two bearings 101, and the outer ring of the bearing 101 is fixed with a support block 102. The bottom of the support block 102 is fixed with a support leg, which is fixed to the ground and realizes the rotation of the drum 2 under the drive of the driving member, wherein the driving member is composed of a first gear and a second gear fixed on one side of the drum 2, the first gear and the second gear are meshed, and the first gear is driven to rotate by the driving motor on the driving member, and finally the second gear is driven to rotate by the first gear to realize the rotation of the drum 2. It should also be understood that the two ends of the drum 2 are fixed on the inner rings of the two bearings 101, thereby ensuring the sealing state of both sides of the drum 2 to prevent sewage from overflowing when the drum 2 rotates.

[0045] like Figure 1 and Figure 3 As shown, a refrigeration component 3 is arranged on the top of the drum 2, wherein the refrigeration component 3 includes an arc-shaped plate and a plurality of cooling pipes fixed on the inner wall of the top of the arc-shaped plate, the cooling pipes are connected to an external cooling machine, and the drum 2 is movably arranged at the bottom of the arc-shaped plate, so that a relatively sealed space is formed between the surface of the drum 2 and the arc-shaped plate, and the space is cooled by the cooling pipe, and the temperature is -5-3 degrees Celsius, thereby realizing that the refrigeration component 3 cools the top cylinder of the drum 2.

[0046] like Figure 4 As shown, a plurality of protrusions 201 distributed in an array are fixed to the inner wall of the drum 2, and the angle formed between the two side surfaces of the protrusion 201 is 60-120°. An oil scraping assembly 4 is arranged inside the drum 2, and the mixed oil adhering to the inner wall of the drum 2 is scraped off by the oil scraping assembly 4. An oil delivery assembly 5 is arranged at the bottom of the oil scraping assembly 4, and the scraped mixed oil is output from the drum 2 through the oil delivery assembly 5. Specifically, as shown in FIG. Figure 4-Figure 6 As shown, the oil scraper assembly 4 includes a movable plate 401, a scraper plate 402 inclined to the right is fixed on the top of the movable plate 401, and the top surface of the scraper plate 402 is in contact with the inner wall of the drum 2, a horizontal extension plate 403 is fixed on the side of the movable plate 401, and a horizontal fixed plate 404 is arranged at the bottom of the horizontal extension plate 403, wherein the horizontal extension plate 403 and the horizontal fixed plate 404 are both parallel to the ground, and both sides of the horizontal fixed plate 404 are fixed to the inner hole wall of the support block 102 through the extension block, so the horizontal fixed plate 404 will not interfere with the rotation of the drum 2, and a plurality of plug rods 405 are fixed on the top of the horizontal fixed plate 404, and the plug rods 405 are movably plugged with the horizontal extension plate 403, and a plurality of springs are fixed between the horizontal extension plate 403 and the horizontal fixed plate 404, and the plug rods 405 are located in the spiral coil of the spring.

[0047] like Figure 4-Figure 6 As shown, the oil delivery assembly 5 includes a rotating shaft, an arc-shaped enclosure plate 501 and a closed enclosure plate 502. The arc-shaped enclosure plate 501 is fixed at the bottom of the scraper 402, and an oil inlet is formed on the side of the arc-shaped enclosure plate 501 facing the scraper 402. The scraped oil slides on the scraper 402 and then enters the arc-shaped enclosure plate 501 through the oil inlet. A conveying spiral plate 503 is fixed on the shaft body of the rotating shaft, and a first motor 504 is fixed on the side of the closed enclosure plate 502, and the output end of the first motor 504 is fixed to the end of the rotating shaft.

[0048] It should be noted that the purpose of setting the bump 201 is:

[0049] 1. When the oil is at a low temperature, the movement of oil molecules slows down and the interaction force increases, resulting in a decrease in fluidity and an increase in viscosity. The oil adheres to the inner wall of the drum 2 and as the drum 2 rotates, the oil droplets gather together. Under the action of gravity, part of the oil may enter the sewage along the inner wall of the drum 2. The setting of the protrusion 201 can not only increase the contact area between the inner wall of the drum 2 and the sewage to improve the oil collection efficiency, but also increase the movement of the oil droplets to prevent the oil from entering the sewage again.

[0050] 2. When the drum 2 rotates, the scraper 402 scrapes off the oil attached to the inner wall of the drum 2. When the protrusion 201 contacts the top of the scraper 402, the protrusion 201 generates an extrusion force on the scraper 402. At this time, the spring contracts and the horizontal extension plate 403 moves downward. Since the drum 2 rotates at a fast speed, the scraper 402 moves up and down, causing the scraper 402 to vibrate, thereby separating the solidified oil (fatty oil) attached to the surface of the scraper 402, which not only reduces the number of cleaning times for the scraper 402 but also realizes the continuity of sewage treatment.

[0051] like Figure 1 , Figure 7 and Figure 8 As shown, a separation component 6 is arranged on one side of the oil delivery component 5, wherein the separation component 6 includes a refrigeration box and a separation part. Under the action of the refrigerator, the temperature of the refrigeration box is -3-3°C, and the oil outlet of the oil delivery component 5 is fixedly connected to the refrigeration box through a discharge pipe 505, and the mixed oil entering the refrigeration box is separated by the separation part. A sewage inlet pipe 14 and a fourth connecting pipe 13 are respectively arranged on both sides of the drum 2, and the filtered kitchen sewage enters the bottom of the drum 2 through the sewage inlet pipe 14. It should be noted that this scheme utilizes the time characteristics of the catering industry to treat the kitchen sewage, that is, when the kitchen sewage enters the bottom of the drum 2 through the sewage inlet pipe 14, the drum 2 does not rotate, but only stores the kitchen sewage. The treatment device starts working at night or after get off work at noon.

[0052] like Figure 8As shown, a partition 601 is fixed at the bottom of the refrigerating box, and the partition 601 divides the refrigerating box into a fat oil separation chamber and a vegetable oil separation chamber. The separation part includes an inclined plate 603, and a discharge pipe 505 is located at the top of the inclined plate 603. The oil to be separated falls into the top of the inclined plate 603 through the discharge pipe 505 and slides downward through the inclined plate 603. A tensioning shaft 605 and at least two horizontally distributed rollers 604 are movably connected between the side walls of the refrigerating box. The tensioning shaft 605 is located at the bottom of the roller 604. An oil absorption belt 607 is arranged between the tensioning shaft 605 and the roller 604, and a pressure roller 606 is also fixed between the side walls of the refrigeration box. The pressure roller 606 is located directly below the tensioning shaft 605, and the pressure roller 606 is squeezed with the oil absorption belt 607. In this embodiment, the output side of the oil absorption belt 607 is located directly above the fat oil separation chamber, and the pressure roller 606 and the tensioning shaft 605 are located directly above the vegetable oil separation chamber. A driving member is arranged on the outside of the refrigeration box, and the oil absorption belt 607 is moved by the driving member.

[0053] In order to prevent the solidified vegetable oil from accumulating on the top of the inclined plate 603, thereby reducing the separation efficiency, in a specific embodiment of the present scheme, a horizontal axis 602 is fixed between the side walls of the refrigeration box, the top of the inclined plate 603 is movably connected to the horizontal axis 602, a movable axis is movably connected between the side walls of the refrigeration box, a cam 608 is fixed on the shaft body of the movable shaft, and the outer surface of the cam 608 is in contact with the bottom of the inclined plate 603, fixed wheels 609 are fixed on the shaft bodies of the movable shaft and roller 604 extending out of the refrigeration box, belts 612 are connected between the fixed wheels 609, a support frame 610 is fixed to the side wall of the refrigeration box, a second motor 611 is fixed to the side of the support frame 610, and the output end of the second motor 611 is fixed to the end of the movable shaft or roller 604.

[0054] To ensure the quality of sewage purification, Figure 1 As shown, the sewage inlet pipe 14 is connected to the fourth connecting pipe 13, and the fourth liquid pump 132, the second water quality detector 131 and the fourth solenoid valve 133 are connected in sequence in the extension direction of the fourth connecting pipe 13 toward the sewage inlet pipe 14; the first connecting pipe 7 is fixedly connected to the pipe body of the fourth connecting pipe 13, and the first solenoid valve 701 and the first liquid pump 702 are connected in sequence in the extension direction of the first connecting pipe 7; the output side of the first connecting pipe 7 is connected to a secondary purification device, and the water discharged from the first connecting pipe 7 is further purified by the secondary purification device, and the purpose of further purification is to remove the protein particles contained in the sewage.

[0055] like Figure 2As shown, the secondary purification device includes an ultrasonic cavitation component 8, a flocculation component 11 and a filter component 12. The ultrasonic cavitation component 8 can generate shock waves, thereby causing a cavitation effect in the sewage. The cavitation effect is sufficient to open chemical bonds and promote chemical reactions including molecular fragmentation and the formation of free radicals, thereby achieving the purpose of degrading and decomposing organic matter. The flocculation component 11 flocculates protein ions in the sewage by adding flocculants. It can be known that after the organic matter forms organic ions through the ultrasonic cavitation component 8, it is flocculated through the flocculation component 11, which can improve the purification effect. The filter component 12 filters the flocculated water, and the filtered water can be used as domestic water for secondary use. The ultrasonic cavitation component 8, the flocculation component 11 and the filter component 12 are all existing technologies and will not be repeated in this solution.

[0056] Among them, a second connecting pipe 801 is fixedly connected between the ultrasonic cavitation component 8 and the flocculation component 11, and the second connecting pipe 801 is respectively connected to the second liquid pump 802, the first water quality detector 803 and the second solenoid valve 9. The second connecting pipe 801 located at the bottom of the second solenoid valve 9 is connected to a return pipe on the body, and the return pipe is connected to the third solenoid valve 10. A third connecting pipe 111 is fixedly connected between the flocculation component 11 and the filtration component 12, and the third connecting pipe 111 is connected to the body of the third liquid pump 112.

[0057] In addition, the device in the present application also includes an intelligent control system, which is electrically connected to the fourth liquid pump 132, the second water quality detector 131, the fourth solenoid valve 133, the first solenoid valve 701, the first liquid pump 702, the second liquid pump 802, the first water quality detector 803, the second solenoid valve 9, the third solenoid valve 10 and the third liquid pump 112 respectively.

[0058] To supplement the present solution, the filtered kitchen sewage enters the bottom of the drum 2 through the sewage inlet pipe 14 (the amount of sewage discharged at a time is 1 / 3 of the volume of the drum 2, so that it will not be discharged from the holes on the bearing 101 and the support block 102). When the sewage is not discharged, the control system controls the refrigeration component 3 to refrigerate and drives the drum 2 to rotate through the driving component. The vegetable oil and fat oil float on the top of the kitchen sewage. As the drum 2 rotates, the two oils and water are attached to the side wall of the drum 2 in a film-like shape. When the two oils and water rotate to the bottom of the refrigeration component 3, due to the low temperature at the top of the drum 2, the fluidity of the vegetable oil and fat oil is weakened and the viscosity is increased, and the water will flow into the kitchen sewage along the wall of the drum 2. As the drum 2 continues to rotate, the temperature of the vegetable oil and fat oil is further reduced, and the fat oil will solidify. At this time, the vegetable oil will also rotate with the drum 2 due to the weakened fluidity and increased viscosity, and part of the vegetable oil will increase in weight due to aggregation, so that it will separate from the protrusion 201 under the action of gravity and fall to the top of the scraper 402. As the drum 2 rotates, the scraper 402 scrapes off the oil attached to the inner wall of the drum 2. When the protrusion 201 contacts the top of the scraper 402, the protrusion 201 exerts an extrusion force on the scraper 402. At this time, the spring contracts and the horizontal extension plate 403 moves downward. As the drum 2 rotates at a high speed, the scraper 402 moves up and down, causing the scraper 402 to vibrate, thereby separating the fat oil attached to the surface of the scraper 402 from the scraper 402. The solidified fat oil and the fluid vegetable oil are discharged from the oil delivery component 5. The fat oil is further solidified after entering the refrigeration box (to prevent it from melting during the oil delivery component 5) and enters the top of the oil absorption belt 607 through the inclined plate 603. At this time, the vegetable oil is absorbed by the oil absorption belt 607. As the oil absorption belt 607 is transported, the solidified fat oil falls into the collection frame in the fat oil separation chamber, and the oil absorbed on the oil absorption belt 607 is separated from the oil absorption belt 607 under the pressure of the pressure roller 606, and then enters the vegetable oil separation chamber for collection;

[0059] At the same time, the control system controls the first solenoid valve 701 to close and the fourth solenoid valve 133 to open, the fourth liquid pump 132 pumps the kitchen sewage in the drum 2 into the fourth connecting pipe 13, and detects the oil content in the sewage through the second water quality detector 131, so as to realize real-time detection of the kitchen sewage in the drum 2. When the oil index of the kitchen sewage meets the standard, the fourth solenoid valve 133 of the control system is closed and the first solenoid valve 701 is opened, and the first liquid pump 702 pumps the deoiled water into the ultrasonic cavitation component 8 for cavitation treatment. According to the same principle, when the first water quality detector 803 detects that the protein index meets the standard, the deoiled, cavitated and flocculated water is pumped into the filter component 12 for filtration through the second liquid pump 802 and the third liquid pump 112. The filtered water can be used as domestic water. Similarly, the separated vegetable oil and fatty oil are used for corresponding reproduction.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
