[0049] The specific implementation of the present application is further described below with reference to the accompanying drawings.

[0050] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

[0051] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0052] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0053] like Figure 1-3 As shown, the coal chemical wastewater oil removal system in one embodiment of the present application includes a treatment tank 1, a wastewater input pipe 2 connected to the treatment tank 1, a wastewater output pipe 3 connected to the treatment tank 1 and located above the wastewater input pipe 2, an adsorption device 4 installed inside the treatment tank 1, and a foam collection device 54 connected to the treatment tank 1 and located above the adsorption device 4.

[0054] An aeration pump 6 is provided between the wastewater inlet pipe 2 and the treatment tank 1 .

[0055] The adsorption device 4 comprises a locking mechanism 41, an alarm mechanism 42 and an adsorption net cylinder 43 filled with adsorption particles.

[0056] The locking mechanism 41 is detachably connected to the mounting bracket 7 in the processing tank 1 .

[0057] The alarm mechanism 42 is connected to the side wall of the adsorption net cylinder 43 . After the adsorption particles adsorb grease and expand, the adsorption net cylinder 43 is driven to expand and can trigger the alarm mechanism 42 .

[0058] In this embodiment, the treatment tank 1 is connected to a wastewater input pipe 2 and a wastewater output pipe 3, wherein the wastewater input pipe 2 is located below the wastewater output pipe 3, and an adsorption device 4 is installed inside the treatment tank 1, the adsorption device 4 includes a locking mechanism 41, an alarm mechanism 42 and an adsorption net tube 43 filled with adsorption particles, wherein the locking mechanism 41 is detachably connected to the mounting bracket 7 in the treatment tank 1, and the alarm mechanism 42 is connected to the side wall of the adsorption net tube 43, when the adsorption particles adsorb grease and expand to saturation, the adsorption net tube 43 is also driven to expand until it can trigger the alarm mechanism 42, thereby reminding the technician to replace the new adsorption net tube 43, and the wastewater after degreasing will leave the treatment tank 1 through the wastewater output pipe 3.

[0059] The treatment tank 1 is also connected to a foam collecting device 5, which is arranged above the adsorption device 4, and an aeration pump 6 is also arranged between the wastewater input pipe 2 and the treatment tank 1. The gas provided by the aeration pump 6 can promote the buoyancy and emulsification of oil, so that part of the oil forms oil foam, which enters the foam collecting device 5 after passing through the treatment tank 1. The foam generated during the treatment process can be effectively collected, thereby preventing the foam from overflowing or interfering with the treatment process, thereby improving the stability and oil removal effect of the system.

[0060] Specifically, wastewater enters the treatment tank 1 from the wastewater input pipe 2 through the aeration pump 6, part of the grease is wrapped by the gas in the aeration pump 6 to form oil foam and enters the foam collection device 5, and the remaining grease is also emulsified by the gas, thereby being more easily adsorbed. The grease contacts the adsorption particles in the adsorption net tube 43 and is thereby adsorbed by the adsorption particles. The adsorption particles expand after adsorbing the grease, and the adsorption net tube 43 is also driven to expand. When it approaches saturation, the adsorption net tube 43 triggers the alarm mechanism 42, thereby reminding the technician to replace the new adsorption net tube 43.

[0061] When replacing, the technicians can use the locking mechanism 41 to more conveniently and quickly remove and replace the adsorption device 4, which simplifies the operation process of maintaining and replacing the adsorption device 4 and improves the maintenance efficiency of the system.

[0062] like Figure 2 and Figure 4-5 As shown, in one embodiment, the mounting bracket 7 includes an annular frame 71 and a plurality of support frames 72 evenly arranged on the annular frame 71 .

[0063] The annular frame 71 is disposed around the processing tank 11 , and each support frame 72 is provided with a plurality of clamping holes 73 .

[0064] The adsorption device 4 further includes a device body 44 , which is detachably mounted in the clamping hole 73 via a locking mechanism 41 .

[0065] In this embodiment, the mounting bracket 7 inside the processing tank 1 includes an annular frame 71 and a plurality of support frames 72, wherein the annular frame 71 is arranged around the processing tank 1 and is arranged above the processing tank 1, and a plurality of support frames 72 are evenly arranged on the annular frame 71. The plurality of support frames 72 in this embodiment are oppositely and evenly arranged, providing uniform supporting force, and a plurality of clamping holes 73 are arranged on each support frame 72, and the device body 44 in the adsorption device 4 can be detachably installed in the clamping hole 73 through the locking mechanism 41.

[0066] The setting of the support frame 72 and the card hole 73 fully utilizes the space inside the processing tank 1 and reasonably arranges the adsorption device 4, which helps to improve the space utilization rate of the system. The design of the annular frame 71 and the support frame 72 provides a uniform supporting force for the adsorption device 4, so that the adsorption device 4 can be stable inside the processing tank 1 and prevent displacement due to vibration or other factors during operation, thereby improving the stability of the system.

[0067] The annular frame 71 is arranged on the upper part of the processing tank 1, so that there is no need to make large-scale changes to the interior of the processing tank 1, thereby reducing the construction difficulty and material costs. The cooperation between the locking mechanism 41 and the card hole 73 also makes it more convenient to install, maintain and replace the adsorption device 4, further reducing labor costs and working hours.

[0068] like Figure 5-6 As shown, in another embodiment, the adsorption net cylinder 43 is connected to the lower end of the device body 44, and a first detection space 45 is provided inside the device body 44.

[0069] A detection hole 731 is formed on the inner wall of the locking hole 73 , a second detection space 74 is disposed inside the supporting frame 72 , and the detection hole 731 is communicated with the second detection space 74 .

[0070] The alarm mechanism 42 includes a first push rod 421 in the first detection space 45 , a second push rod 422 connected to the first push rod 421 and in the second detection space 74 , a switch element 423 in the second detection space 74 , and an alarm element 424 electrically connected to the switch element 423 .

[0071] One end of the first push rod 421 extends out of the first detection space 45 and is connected to the side wall of the adsorption net cylinder 43 , and the other end of the first push rod 421 is connected to the second push rod 422 , and the second push rod 422 is connected to the switch 423 .

[0072] In this embodiment, the upper end of the adsorption net cylinder 43 is connected to the lower end of the device body 44, and a first detection space 45 is further provided inside the device body 44. A first push rod 421 is provided inside the first detection space 45, and one end of the first push rod 421 extends out from the first detection space 45 and is connected to the side wall of the adsorption net cylinder 43, so as to detect the expansion of the adsorption net cylinder 43, and a detection hole 731 is opened on the inner wall of the card hole 73, and a second detection space 74 is provided inside the support frame 72, and the detection hole 731 is connected to the second detection space 74. When the adsorption device 4 is installed in the card hole 73, the first detection space 45 will be connected to the second detection space 74 through the detection hole 731, and the other end of the first push rod 421 will be connected to the second push rod 422 in the second detection space 74. A switch component 423 connected to the second push rod 422 is also provided inside the second detection space 74, and the switch component 423 is also electrically connected to the alarm component 424.

[0073] Specifically, when the adsorption particles in the adsorption net tube 43 absorb grease and expand to a certain extent, the adsorption net tube 43 will be driven to expand together, thereby pushing the first push rod 421. The first push rod 421 will move inside the first detection space 45. The other end of the first push rod 421 is connected to the second push rod 422 inside the second detection space 74, which will drive the second push rod 422 to move together. The second push rod 422 will trigger the switch component 423, so that the alarm component 424 is triggered, reminding the technician to replace the adsorption device 4, thereby realizing real-time monitoring of the grease adsorption status of the adsorption device 4 and ensuring the stable operation of the system.

[0074] By setting the detection hole 731, the first detection space 45 and the second detection space 74, and setting the alarm mechanism 42 therein, a compact structure is achieved. The integrated design reduces the need for external sensors, simplifies the system structure, allows technicians to conduct inspections and maintenance more conveniently, and reduces costs.

[0075] In this embodiment, the alarm component 424 is arranged on the edge of the ring frame 71, which can make it easier for technicians to see. The alarm component 424 can be a flash light / sound alarm / sound and light alarm, and can also be connected to a central monitoring system to update the alarm status in real time.

[0076] like Figure 5-8 As shown, in another embodiment, the locking mechanism 41 includes a rotating ring 411 , a rotating shaft 412 , a first gear 413 , two racks 414 and two fixing members 415 .

[0077] A fixed space 46 is provided inside the device body 44 .

[0078] The rotating ring 411 is rotatably disposed at the upper end of the device body 44, the rotating shaft 412 is fixedly connected to the rotating ring 411, the rotating shaft 412 extends from the upper end of the device body 44, the axial hole of the first gear 413 is fixedly connected to the lower end of the rotating shaft 412, two racks 414 are disposed on opposite sides of the first gear 413 and are respectively engaged with the first gear 413, each fixing member 415 is respectively fixedly connected to a rack 414, and the two fixing members 415 partially extend out of both sides of the device body 44.

[0079] In this embodiment, a fixed space 46 is provided inside the device body 44, a rotating ring 411 is rotatably provided at the upper end of the device body 44, and the rotating ring 411 is fixedly connected to a rotating shaft 412, the rotating shaft 412 extends from the upper end of the device body 44 into the fixed space 46, and the lower end of the rotating shaft 412 is fixedly connected to a first gear 413, and two gears are provided on opposite sides of the first gear 413 and are respectively meshed with the first gear 413, and each rack 414 is fixedly connected to a fixing member 415, and the two fixing members 415 partially extend out of the two sides of the device body 44 respectively.

[0080] Specifically, the technician can rotate the rotating ring 411 to drive the rotation of the rotating shaft 412 and the first gear 413, so that the two racks 414 move laterally, thereby driving the fixing member 415 to move, and the two fixing members 415 move inward or outward synchronously. The operator only needs to rotate the rotating ring 411 to control the fixing member 415 to extend or retract in the device body 44. The fixing member 415 can be snapped into the snap hole 73, thereby realizing the detachable installation of the adsorption device 4 in the mounting bracket 7, reducing the operation process of the technician and improving efficiency.

[0081] The meshing between the rack 414 and the first gear 413 provides a stable mechanical connection, enabling reliable locking and unlocking, and ensuring that the system can be stably fixed in position when needed, or safely unlocked when needed.

[0082] The locking mechanism 41 is compactly designed. The rotating shaft 412, the first gear 413, the rack 414 and the fixing part 415 are effectively integrated inside the device body 44. The technician only needs to operate the rotating ring 411 to lock or unlock the adsorption device 4, which saves space, makes the overall structure more concise, and improves space utilization.

[0083] like Figure 5 , Figure 6 and Fig. 9 As shown, in one of the preferred embodiments, at least one positioning block 47 is disposed on the device body 44 , and the positioning block 47 is disposed below / above the protruding portion of the fixing member 415 .

[0084] The hole wall of each locking hole 73 is provided with two positioning grooves 75 for locking the fixing member 415 .

[0085] When the adsorption device 4 is inserted into the clamping hole 73 , the positioning block 47 is aligned with the positioning groove 75 .

[0086] In this preferred embodiment, two positioning blocks 47 are further provided on the device body 44, each positioning block 47 is respectively arranged below / above the protruding part of the fixing member 415, and the hole wall of each clamping hole 73 is provided with two positioning grooves 75. When the technician needs to insert the adsorption device 4 into the clamping hole 73, the positioning block 47 can be aligned with the position of the positioning groove 75, and then the adsorption device 4 is inserted. At this time, the rotating ring 411 is rotated again, and the fixing member 415 extends from the inside of the device body 44 and is clamped in the inside of the positioning groove 75, so that the adsorption device 4 and the mounting bracket 7 can be detachably installed, avoiding unstable installation due to inaccurate alignment, thereby improving the overall stability of the system and the work efficiency of the technician. The clamping between the fixing member 415 and the positioning groove 75 can enhance the stability of the adsorption device 4 and prevent loosening or displacement due to vibration or other factors during operation.

[0087] like Figure 7 As shown, in one embodiment, a filter cylinder 48 is disposed outside the adsorption cylinder 43 .

[0088] In this embodiment, a filter cylinder 48 is also provided on the outside of the adsorption net cylinder 43, which effectively removes large particles of impurities and solid matter in the wastewater, thereby reducing the load entering the interior of the adsorption net cylinder 43, reducing system failure problems caused by blockage, ensuring that the adsorption particles can better absorb grease in the wastewater, improving the efficiency of wastewater treatment, and extending the service life of the adsorption device 4, thereby optimizing the oil removal performance of the overall system.

[0089] In one preferred embodiment, the adsorption net cylinder 43 includes a single-layer cylinder and a double-layer cylinder. The double-layer cylinder includes two layers of semi-cylindrical side walls arranged in the same direction. The upper ends of the two layers of semi-cylindrical side walls are closed, and a restricted space is set between the two layers of semi-cylindrical side walls.

[0090] One side of the single-layer cylinder is embedded in the restricted space, and the side wall of the other side of the single-layer cylinder is connected to the alarm mechanism 42.

[0091] In this preferred embodiment, the double-layer cylinder includes two layers of semi-cylindrical side walls, and the upper ends of the two layers of semi-cylindrical side walls are closed, and a restricted space is set between the two layers of semi-cylindrical side walls. One half side of the single-layer cylinder is embedded in the interior of the restricted space, and the other half side is connected to the alarm mechanism 42.

[0092] Specifically, the inner and outer semi-cylindrical side walls of the double-layer cylinder are used to limit the expansion and deformation of one half side of the single-layer cylinder. The other half side of the single-layer cylinder is connected to the alarm mechanism 42. When the adsorption particles adsorb a certain amount of grease and expand, the double-layer cylinder will limit one side of the single-layer cylinder, allowing the other side to expand faster. When the side of the single-layer cylinder connected to the alarm mechanism 42 expands to a certain extent, the alarm mechanism 42 will be triggered, thereby reminding technicians to replace the adsorption device 4. It can respond more quickly when the adsorbed grease expands to a certain extent, preventing structural damage or other failures caused by excessive expansion, thereby improving the safety and stability of the system.

[0093] like Figure 2 and Fig.10 As shown, in another embodiment, the foam collecting device 5 includes a foam collecting pipe 51 , a foam collecting bin 52 , an automatic scraper mechanism 53 and a foam discharge port 54 .

[0094] The foam collecting bin 52 is arranged at the upper end of the processing tank 1 and is connected to the processing tank 1 through the foam collecting pipe 51. The automatic scraper mechanism 53 is arranged in the foam collecting bin 52. The automatic scraper mechanism 53 is used to scrape off the foam in the foam collecting bin 52. A foam discharge outlet 54 is opened at the bottom of the foam collecting bin 52.

[0095] In this embodiment, the foam collecting device 5 connected to the treatment tank 1 and located above the adsorption device 4 includes a foam collecting pipe 51, a foam collecting bin 52, an automatic scraper mechanism 53 and a foam discharge port 54, wherein the upper end of the foam collecting pipe 51 is connected to the foam collecting bin 52, and the lower end of the foam collecting pipe 51 is connected to the treatment tank 1, for transporting the foam in the treatment tank 1 to the foam collecting bin 52, and an automatic scraper mechanism 53 is also provided inside the foam collecting bin 52 for scraping off the foam in the foam collecting bin 52 so that it does not stick to the inside of the foam collecting bin 52, and a foam discharge port 54 is also provided at the bottom of the foam collecting bin 52, and the foam is discharged from the foam collection bin 52 from the foam discharge port 54.

[0096] Specifically, the foam collection bin 52 guides the foam in the treatment tank 1 together through the foam collection pipe 51, which is convenient for centralized processing and management and improves the foam collection efficiency. The automatic scraper mechanism 53 can automatically scrape the foam, reducing the maintenance workload of the operator and reducing the need for manual intervention and maintenance costs.

[0097] A foam discharge outlet 54 is provided at the bottom of the foam collection bin 52, which can effectively discharge the collected foam, prevent excessive accumulation of foam in the foam collection bin 52, prevent blockage or other failures caused by excessive foam, and significantly improve the efficiency and reliability of the wastewater treatment system.

[0098] like Figure 2 and Fig.10 As shown, in one embodiment, the automatic scraper mechanism 53 includes a scraper 531 , a power member 532 , a mounting plate 533 , a second gear 534 , and a gear ring 535 .

[0099] The gear ring 535 is arranged around the top of the foam collecting bin 52, the mounting plate 533 is arranged on the side wall of the foam collecting bin 52, the power member 532 is mounted on the mounting plate 533, the second gear 534 is connected to the output end of the power member 532, the second gear 534 is meshed with the gear ring 535, the upper end of the scraper 531 is connected to the gear ring 535, and the scraper 531 abuts against the inner wall of the foam collecting bin 52.

[0100] In this embodiment, the automatic scraper mechanism 53 arranged in the foam collecting bin 52 includes a scraper 531, a power piece 532, a mounting plate 533, a second gear 534 and a gear ring 535, wherein the mounting plate 533 is arranged on the outer wall of the foam collecting bin 52, the power piece 532 is arranged on the mounting plate 533, the output end of the power piece 532 is connected to the second gear 534, and a gear ring 535 is arranged around the top of the foam collecting bin 52, the second gear 534 is meshed with the gear ring 535, and the upper end of the scraper 531 is connected to the gear ring 535, and the scraper 531 abuts against the inner wall of the foam collecting bin 52.

[0101] Specifically, the power member 532 drives the second gear 534 to rotate, and the second gear 534 is engaged with the gear ring 535, thereby transmitting the power to the gear ring 535. The gear ring 535 rotates around the top of the foam collecting bin 52, so that the scraper 531 can also automatically rotate in the foam collecting bin 52, thereby effectively scraping off the foam inside the foam collecting bin 52, reducing manual intervention, and improving the efficiency of foam processing.

[0102] The simple meshing between the gear ring 535 and the second gear 534 reduces the wear of the moving parts, thereby improving the overall reliability and durability of the system and simplifying the maintenance of the system. The operator can easily access and inspect these components to perform necessary maintenance and adjustments.

[0103] like Fig.10 As shown, in one of the preferred embodiments, the automatic scraper mechanism 53 also includes a matching protruding ring 536, which is arranged at the bottom of the gear ring 535.

[0104] The outer peripheral wall of the foam collecting bin 52 is further provided with a matching space 55 , into which the matching protruding ring 536 extends, and the matching protruding ring 536 abuts against the inner wall of the matching space 55 .

[0105] In this preferred embodiment, a mating space 55 is provided on the outer peripheral wall of the foam collecting bin 52, and a mating convex ring 536 is provided at the bottom of the gear ring 535. The mating convex ring 536 extends into the mating space 55 and abuts against the inner wall of the mating space 55. When the gear ring 535 rotates around the foam collecting bin 52, the mating convex ring 536 rotates inside the mating space 55 along with the rotation of the gear ring 535, thereby reducing vibration and noise during operation, improving the stability of the system, making the gear ring 535 more stable on the top of the foam collecting bin 52, enhancing the structural stability of the automatic scraper mechanism 53, and reducing the risk of failure caused by loosening or deformation of mechanical parts.

[0106] The cooperation between the mating convex ring 536 and the mating space 55 also ensures the precise positioning of the gear ring 535. The mating convex ring 536 abuts against the mating space 55, which can avoid displacement or rotational instability of the gear ring 535 during rotation, thereby improving the working stability of the automatic scraper mechanism 53, while also improving the installation accuracy and reducing subsequent adjustment work caused by misalignment.

[0107] like Figure 1-2 and Fig.10 As shown, in one embodiment, the foam discharge port 54 is connected to a foam collecting tank 56 , and a foam output pump 57 is further provided between the foam discharge port 54 and the foam collecting tank 56 .

[0108] In this embodiment, a foam collecting tank 56 is also connected to the foam discharge outlet 54, and a foam output pump 57 is also arranged in series between the foam discharge outlet 54 and the foam collecting tank 56, so as to effectively transport the foam from the foam discharge outlet 54 to the foam collecting tank 56, thereby improving the foam transfer efficiency, preventing excessive foam accumulation in the foam collecting bin 52, and enhancing the overall reliability of the system. At the same time, technicians can adjust the power of the foam output pump 57 to cope with different foam quantities and processing requirements, so that the system can be suitable for more working environments.

[0109] The above description is only the principle and preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this field, the implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included in the technical scope of the present invention. On the basis of the principle of the present application, several other variations can be made, which should also be regarded as the protection scope of the present application.
