[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] The present application embodiment provides a recycling processing device 100, see Figure 1 and Figure 2 As shown, the recycling and processing equipment 100 includes: a first recycling device 10, a second recycling device 20 and a processing device 30, the first recycling device 10 has a first recycling space 11 and a first inlet 12 and a first outlet 13 connected thereto; the second recycling device 20 has a second recycling space 21 and a second inlet 22 connected thereto; the processing device 30 has a processing space 31 and a first opening 32, a second opening 33, a third opening 34 and a fourth opening 35 connected thereto, the first opening 32 is connected to the first outlet 13, the second opening 33 is connected to the second inlet 22, a first filtering structure 36 and an oil-water separation structure 37 are sequentially arranged between the first opening 32 and the second opening 33, the third opening 34 corresponds to between the first filtering structure 36 and the oil-water separation structure 37, and the fourth opening 35 corresponds to between the first opening 32 and the first filtering structure 36.

[0031] Specifically, the first recovery space 11 of the first recovery device 10 has a first inlet 12 and a first outlet 13. The first inlet 12 allows the dust generated by the production equipment, the fallen urea and other recyclables to enter the first recovery space 11 through the first inlet 12, and the liquid (such as clean water) that dissolves the recyclables can also enter the first recovery space 11 through the first inlet 12; the first outlet 13 can send out the dissolved liquid in the first recovery space 11. The number of first recovery devices 10 can be one or more. When the number of first recovery devices 10 is multiple, the multiple first recovery devices 10 can be set at different positions to recover the dust, fallen urea and other recyclables from different production equipment nearby. Here, because the dust is in the form of plates and blocks, and the fallen urea is in the form of particles, a large-sized inlet is required to allow the dust and fallen urea to enter the first recovery space 11. For this purpose, refer to Figure 1 As shown, the first recovery device 10 may include: a recovery funnel 14 and an upper cover 15. The recovery funnel 14 has a large-sized inlet and a small-sized outlet that are connected to each other. The large-sized inlet allows dust, fallen urea, etc. to enter the first recovery space 11. The small-sized opening can be the first outlet 13 to output the dissolved liquid. The side wall of the recovery funnel 14 is also provided with a first inlet 12. The size of the first inlet 12 is smaller than the size of the large-sized inlet of the recovery funnel 14 to transport clean water to the first recovery space 11. The upper cover 15 is rotatably connected to the large-sized inlet of the recovery funnel 14 so that it can rotate relative to the recovery funnel 14 and close the large-sized inlet after dust and urea enter the first recovery space 11, thereby preventing other foreign matter from entering the recovery funnel 14 through the large-sized inlet and affecting the quality of the recovered product.

[0032] The second recovery space 21 of the second recovery device 20 has a second inlet 22. The second interface allows the recovery liquid treated by the treatment device 30 to enter the second recovery space 21 to be further processed and formed into new products such as urea. The number of second recovery devices 20 can be one or more. When the number of second recovery devices 20 is more than one, the recovery liquid treated by the treatment device 30 can fill more than one second recovery device 20 in sequence.

[0033] The first opening 32 of the processing space 31 on the processing device 30 is connected to the first recovery space 11, and the second opening 33 is connected to the second recovery space 21. In this way, the processing space 31 can receive the dissolved liquid from the first recovery device 10 through the first opening 32, and after further processing in the processing space 31, the processed recovered liquid is sent to the second recovery device 20 through the second opening 33 to be further made into a product. A first filtering structure 36 and an oil-water separation structure 37 are sequentially arranged between the first opening 32 and the second opening 33 of the processing space 31. Therefore, the processing space 31 can first filter the dissolved liquid through the first filtering structure 36 to remove large particles, and then separate the oil through the oil-water separation structure 37 to obtain a recovered liquid with less or even no large particles and less or even no oil. The third opening 34 corresponds to between the first filter structure 36 and the oil-water separation structure 37, and the fourth opening 35 corresponds to between the first opening 32 and the first filter structure 36, so that clean water can be transported to between the first filter structure 36 and the oil-water separation structure 37 through the third opening 34, and the clean water can transport the dirt on the first filter structure 36 and the oil stains between the first filter structure 36 and the oil-water separation structure 37 in reverse to between the first filter structure 36 and the first opening 32, and be sent out through the fourth opening 35 between the first filter structure 36 and the first opening 32 to clean the processing space 31.

[0034] In this embodiment, the recycling and processing equipment 100 includes a first recycling device 10, a processing device 30 and a second recycling device 20 which are connected in sequence. The first recycling device 10 can recycle dust generated by the production equipment, urea on the ground and other recyclable recyclables and liquid for dissolving the recyclables to form a dissolved liquid. The first filtering structure 36 and the oil-water separation structure 37 of the processing device 30 can filter the dissolved liquid of the first recycling device 10 and separate the oil and water in turn to obtain a higher purity recycled liquid. The second recycling device 20 can receive the recycled liquid to be further processed and formed into new urea and other products, so as to reduce the waste of production materials and the increase in costs. In addition, the clean water can enter the processing space 31 between the first filtering structure 36 and the oil-water separation structure 37 through the third opening 34 to take away the oil in the space, the stolen goods on the inner wall of the space and the dirt on the first filtering structure 36 and discharge them through the fourth opening 35, so as to improve the quality of the recycled liquid after treatment and extend the service life of the first filtering structure 36 and the oil-water separation structure 37.

[0035] In some embodiments, see Figure 2 As shown, the third opening 34 is disposed adjacent to the oil-water separation structure 37 ; and the fourth opening 35 is disposed adjacent to the first filtering structure 36 .

[0036] When the third opening 34 is disposed adjacent to the oil-water separation structure 37, clean water flowing at a high speed can be fed between the first filter structure 36 and the oil-water separation structure 37 through the third opening 34, so that the clean water entering the third opening 34 can flush the oil-water separation structure 37 at a high speed, so that the oil dirt adhering to the oil-water separation structure 37 can be further separated, and then discharged through the fourth opening 35, so that the quality of the recovered liquid after treatment can be further improved, and the service life of the oil-water separation structure 37 can be extended. Here, the third opening 34 can also be disposed adjacent to the oil-water separation structure 37 and the first filter structure 36 at the same time, so that the first filter structure 36 can be flushed while flushing the oil-water separation structure 37, so that more dirt on the first filter structure 36 can be flushed down and discharged through the fourth opening 35.

[0037] When the fourth opening 35 is arranged near the first filter structure 36, the dirt on the first filter structure 36, the oil on the oil-water separation structure 37, and the dirt and oil between the first filter structure 36 and the oil-water separation structure 37 brought by the clean water of the third opening 34 can be discharged through the fourth opening 35 at the first time without further adhering to the inner wall of the processing space 31 between the first filter structure 36 and the first outlet 13, thereby further improving the quality of the recovered liquid after treatment and extending the service life of the recovery and processing equipment 100.

[0038] In some embodiments, see Figure 2 As shown, the first inner wall 311 forming the processing space 31 is opposite to the fourth opening 35; the processing device 30 also includes: a first blocking structure 38, the first blocking structure 38 is openably connected to the fourth opening 35, and the two ends of the first filtering structure 36 are respectively abutted against the first inner wall 311 and the first blocking structure 38. In other words, the fourth opening 35 can be blocked by the first blocking structure 38 so that the solution entering the first opening 32 can be processed through the first filtering structure 36 and the oil-water separation structure 37, and the fourth opening 35 can also be opened by the first blocking structure 38 so that the fourth opening 35 cooperates with the third opening 34 to clean the processing space 31; and the two ends of the first filtering structure 36 are respectively abutted against the first inner wall 311 and the first blocking structure 38, so that the first filtering structure 36 can be taken out when the first blocking structure 38 opens the fourth opening 35, and then the first filtering structure 36 can be cleaned more carefully or repaired, replaced, etc.

[0039] Here, the first blocking structure 38 and the fourth opening 35 can be rotatably connected, so that the fourth opening 35 can be rotated to open, and the fourth opening 35 can be rotatably blocked; it can also be a snap-on connection, so that the first blocking structure 38 can be snapped onto the fourth opening 35 to block the fourth opening 35, and the first blocking structure 38 can be unfastened from the fourth opening 35 to open the fourth opening 35; it can also be a sliding connection, so that the fourth opening 35 can be slid open, and the fourth opening 35 can be slid to block; other opening and blocking settings can also be used.

[0040] In some embodiments, see Figure 2 As shown, the first filtering structure 36 includes: a first limiting member 361, a second limiting member 362 and a first filtering member 363; one end of the first limiting member 361 is connected to the first inner wall 311; one end of the second limiting member 362 is connected to the first inner wall 311, and the second limiting member 362 is opposite to the first limiting member 361; the first filtering member 363 is sandwiched between the first limiting member 361 and the second limiting member 362, and respectively abuts against the first inner wall 311 and the first blocking structure 38, and two positions of the first limiting member 361 and the second limiting member 362 opposite to each other are respectively provided with a first avoidance hole (not shown in the figure) and a second avoidance hole (not shown in the figure) that expose two areas of the first filtering member 363 that are opposite to each other.

[0041] Here, the fourth opening 35 is the outflow outlet of the cleaning liquid, and for this reason, it can be set at the lower end of the processing space 31 to reduce the probability of residual cleaning liquid in the processing space 31; when the fourth opening 35 is located at the lower end of the processing space 31, the two ends of the first filter 363 respectively abut the first inner wall 311 and the first blocking structure 38 of the fourth opening 35 so that the first filter 363 is vertically arranged, so that the first filter 363 is sandwiched between the first stopper 361 and the second stopper 362, so that the first stopper 361 and the second stopper 362 can be fixed before the first blocking structure 38 blocks the fourth opening 35, thereby reducing the probability of the first filter 363 falling during the cleaning process. The distance between the first stopper 361 and the second stopper 362 can be less than or equal to the thickness of the first filter 363 so that the first filter 363 can be sandwiched, and the first filter 363 can be a structure such as a filter that can filter impurities such as particles.

[0042] The first and second limiting members 361 and 362 are respectively provided with a first avoidance hole and a second avoidance hole at two positions opposite to each other, which expose two areas of the first filter member 363 opposite to each other. In this way, the solution entering through the first opening 32 can reach the first filter member 363 through the first avoidance hole for filtration, and the filtered liquid can flow toward the oil-water separation structure 37 through the second avoidance hole.

[0043] In this embodiment, the first limit member 361 and the second limit member 362 are respectively arranged on both sides of the first filter element 363 and can clamp the first filter element 363, so as to fix the first filter element 363 and reduce the probability of the first filter element 363 falling during the cleaning process. When the first blocking structure 38 blocks the fourth opening 35, the first filter element 363 is confined between the first inner wall 311, the first limit member 361, the second limit member 362 and the first blocking structure 38. When the first blocking structure 38 opens the fourth opening 35, the first filter element 363 can be pulled to conveniently remove the first filter element 363 for cleaning, maintenance, replacement and other operations.

[0044] In some embodiments, see Figure 2 As shown, the first blocking structure 38 may include: a first flange plate 381, a flow guide tube 382, ​​and a ball valve 383 mounted on the flow guide tube 382. The first flange plate 381 is connected to the fourth opening 35 by bolts. The flow guide tube 382 is connected to the first flange plate 381 and communicates with the processing space 31 through the first flange plate 381. The ball valve 383 is used to control the on-off of the flow guide tube 382. In this way, when the ball valve 383 is open, the cleaning liquid can flow out through the first flange plate 381 and the flow guide tube 382; and when the ball valve 383 is closed, the liquid in the processing space 31 cannot flow out through the first flange plate 381 and the flow guide tube 382.

[0045] In some embodiments, see Figure 2 As shown, the processing space 31 is provided with a fifth opening 39 near the oil-water separation structure 37; the second inner wall 312 forming the recovery space is opposite to the fifth opening 39; the processing device 30 further includes: a second plugging structure 40, which is openably connected to the fifth opening 39, and the two ends of the oil-water separation structure 37 are respectively abutted against the second inner wall 312 and the second plugging structure 40. In this way, the fifth opening 39 can be blocked by the second plugging structure 40, so that the processing space 31 can perform normal processing operations; and during regular inspections, the fifth opening 39 can be opened by the second plugging structure 40 to disassemble the oil-water separation structure 37, so as to further clean, repair, replace, and other operations on the disassembled oil-water separation structure 37.

[0046] Here, the second blocking structure 40 and the fifth opening 39 can be rotatably connected, so that the fifth opening 39 can be rotated to open, and the fifth opening 39 can also be rotatably blocked; it can also be a snap-on connection, so that the second blocking structure 40 can be snapped on the fifth opening 39 to block the fifth opening 39, and the second blocking structure 40 can be removed from the fifth opening 39 to open the fifth opening 39; it can also be a sliding connection, so that the fifth opening 39 can be slid open, and the fifth opening 39 can also be slid to block.

[0047] In some embodiments, see Figure 2 As shown, the oil-water separation structure 37 includes: a third limit member 371, a fourth limit member 372 and a fixed frame 373; one end of the third limit member 371 is connected to the second inner wall 312; one end of the fourth limit member 372 is connected to the second inner wall 312, and the fourth limit member 372 is opposite to the third limit member 371; the fixed frame 373 is arranged between the third limit member 371 and the fourth limit member 372, and respectively abuts against the second inner wall 312 and the second blocking structure 40, and the third limit member 371 and the fourth limit member 372 are respectively provided with a third avoidance hole and a fourth avoidance hole for exposing the inner space of the fixed frame 373 at two positions opposite to each other, and the inner space of the fixed frame 373 is used to fix the oil-water separation membrane 374.

[0048] Specifically, the fixing frame 373 is arranged between the third limiting member 371 and the third limiting member 371 which are opposite to each other so as to limit the fixing frame 373 and the oil-water separation membrane 374 therein, and the fixing frame 373 may be respectively fitted with the two inner walls opposite to each other of the third limiting member 371 and the fourth limiting member 372, or may be spaced apart from at least one of the two surfaces opposite to each other of the third limiting member 371 and the fourth limiting member 372. The fixing frame 373 may be a closed one-circle frame structure, or may be an open one-section frame structure, for example: the fixing frame 373 includes: a first rod, a second rod and a third rod, the two ends of the first rod are respectively connected to one end of the second rod and one end of the third rod, and the second rod and the third rod are opposite to each other, and the three edges of the oil-water separation membrane 374 which are adjacent in sequence are respectively connected to the first rod, the second rod and the third rod.

[0049] The third and fourth limiting members 371 and 372 are respectively provided with a third avoidance hole and a fourth avoidance hole at two positions opposite to each other for exposing the inner space of the fixed frame 373. In this way, the liquid filtered by the first filter structure 36 can reach the oil-water separation membrane 374 through the third avoidance hole for oil-water separation, and the recovered liquid after separation can flow toward the second opening 33 through the fourth avoidance hole.

[0050] In this embodiment, the third limiting member 371 and the fourth limiting member 372 are respectively arranged on both sides of the fixed frame 373 for fixing the oil-water separation membrane 374, so as to limit the fixed frame 373 and further limit the oil-water separation membrane 374. When the second sealing structure 40 blocks the fifth opening 39, the fixed frame 373 provided with the oil-water separation membrane 374 is limited between the second inner wall 312, the third limiting member 371, the fourth limiting member 372 and the second sealing structure 40. When the second sealing structure 40 opens the fifth opening 39, the oil-water separation membrane 374 can be easily disassembled by pulling the fixed frame 373 for cleaning, maintenance, replacement and other operations.

In this way, the perforated plate 41 can bear part of the flow pressure of the solution entering and passing through the first filtering structure 36 via the first inlet 12, thereby reducing the fluid pressure on the oil-water separation membrane 374, so as to reduce the probability of damage to the oil-water separation membrane 374.

[0052] In some embodiments, see Figure 2 As shown, the second blocking structure 40 includes: a first connecting member 401, a second connecting member 402 and a visible glass 403; the first connecting member 401 is connected to the fifth opening 39 and has a first through hole; the second connecting member 402 is detachably connected to the side of the first connecting member 401 away from the fifth opening 39, and has a second through hole, and the second through hole is opposite to the first through hole; the visible glass 403 is arranged between the first connecting member 401 and the second connecting member 402, and covers the first through hole. That is to say, the visible glass 403 and the first connecting member 401 cooperate to block the fifth opening 39, and the second connecting member 402 further fixes the visible glass 403. At the same time, the second through hole on the second connecting member 402 is opposite to the first through hole on the first connecting member 401, and the visible glass 403 is located between the first through hole and the second through hole and covers the visible glass 403, so that the operator can observe the shape of the oil-water separation structure 37 corresponding to the position of the fifth opening 39 through the visible glass 403 on the outside of the processing device 30 to confirm whether it is necessary to open the fifth opening 39 through the second blocking structure 40 to clean, repair, replace, etc. the fixing frame 373 and the oil-water separation membrane 374.

[0053] In a specific implementation, the first connecting member 401 and the second connecting member 402 can both be flanges. The detachable connection between the second connecting member 402 and the first connecting member 401 can facilitate the replacement of the visual glass 403; and the detachable connection between the second connecting member 402 and the first connecting member 401 can be as follows Figure 2 The connection is made by butterfly bolts 404 as shown in the figure, or it can be made by a buckle provided on the second connecting member 402 that can be rotated to buckle on the peripheral side of the first connecting member 401; it can also be other detachable connection methods. In order to improve the sealing performance of the second blocking structure 40, a circle of sealing rubber ring can be connected to the outer edge of the sight glass 403, so that after the second connecting member 402 is connected to the first connecting member 401, the second connecting member 402 and the first connecting member 401 respectively squeeze the circle of sealing rubber ring to achieve this, or other implementation methods can be used.
