[0002] In the existing railway industry, the sewage unloading system is one of the most important facilities, which is used to extract sewage from the train's toilet collection tank and transfer it safely and effectively to the septic tank for treatment. It is mainly composed of a cam main unit and a vacuum pipeline, and a sewage unloading unit is connected. The sewage unloading unit is connected to the train toilet collection tank, and the cam main unit generates negative pressure. The sewage in the train toilet collection tank is sucked by the sewage unloading unit through the sewage discharge pipeline and discharged to the septic tank by the cam main unit.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 5 The utility model provides an embodiment: a waste separation and crushing processing equipment, including a separation tank 1 and a crushing box 2, a sewage inlet 4 and a sewage guide pipe 3 are penetrated in the middle of the separation tank 1, an inclined plate 6 is connected to the inner wall of the separation tank 1 below the sewage inlet 4, a blocking plate 7 is fixedly connected to the inner wall of the separation tank 1 between the sewage guide pipe 3 and the sewage inlet 4, and the left and right chambers of the blocking plate 7 are connected, a primary crushing assembly is arranged inside the crushing box 2, a slag discharge pipe 5 is fixedly connected to the bottom of the separation tank 1, and a secondary separation assembly is fixedly connected to the other end of the slag discharge pipe 5.

[0027] Specifically, the waste first enters the separation tank 1 from the sewage inlet 4 through the main pipeline for sedimentation. Through the isolation and blocking of the inclined plate 6 and the blocking plate 7, the fluid enters the lower part from the inlet and then flows upward from the sewage pipe 3 into the crushing box 2. At this time, the heavier foreign matter remains at the bottom of the separation tank 1 and the slag discharge pipe 5, and is discharged to the septic tank from the bottom slag discharge port without sewage unloading. By integrating the crushing device and the separation device, the cam pump is effectively prevented from getting stuck, and the key parts in the cam pump are protected, which increases the service life, stability and safety of the equipment and reduces the maintenance cost of the equipment.

[0028] Please see attached Figure 3 and attached Figure 8The secondary separation component includes a separation box 14, the outer wall of the separation box 14 is fixedly connected to the bottom end of the slag discharge pipe 5, the upper surface of the separation box 14 is penetrated by a material guide box 15, a conveying component is arranged between the separation box 14 and the material guide box 15, the outer wall of the separation box 14 is fixedly connected to a motor three 22, the driving end of the motor three 22 is fixedly connected to a rotating rod 23, the outer wall of the rotating rod 23 is fixedly connected to a plurality of lifting rods 24, the outer wall of the rotating rod 23 is rotatably connected to the inside of the separation box 14, the inner wall of the separation box 14 is fixedly connected to a plurality of blocking rods 25, and the plurality of lifting rods 24 and the blocking rods 25 are alternately arranged.

[0029] Specifically, heavier foreign matter will enter the separation box 14 through the slag discharge pipe 5, and after being blocked by multiple lifting rods 24 and blocking rods 25, debris that is difficult to separate, such as towels, will be left behind, while smaller debris will enter the guide pipe 27 for processing in the next link. The motor 3 22 is started to drive the rotating rod 23 to drive the multiple lifting rods 24 to rotate, and the larger and softer debris left behind will be carried to the conveying platform composed of multiple secondary conveying rollers 16 and the main drive roller 21. Under the conveyance of the conveying platform, the debris is conveyed to the discharge port 26 and then collected for recycling. In the process of the multiple lifting rods 24 lifting the debris, some of the debris will continue to be blocked by the blocking rods 25. After the debris on the conveying platform is conveyed away, the multiple lifting rods 24 continue to rotate through the middle gap of the conveying platform, and pass through the gaps between the multiple blocking rods 25 to lift up the subsequent debris. This is repeated to complete the conveying of the debris. By designing components to separate soft objects from heavier debris, soft debris such as towels do not need to be discharged into the septic tank, but are collected and processed separately, effectively maintaining the smooth operation of the sewage unloading system, thereby improving the overall efficiency and reliability of the system.

[0030] Please see attached Figure 1 -Attached Figure 2 The outer wall of the material guide box 15 is fixedly connected with a discharge port 26, the outer wall of the discharge port 26 is fixedly connected with a material guide pipe 27, the other end of the material guide pipe 27 is fixedly connected with a crushing tank 28, a secondary crushing assembly is arranged inside the crushing tank 28, and a sewage pipe 34 is fixedly connected to the bottom of the crushing tank 28.

[0032] Specifically, when soft debris is brought onto the conveying platform, motor 20 drives the main drive roller 21 to rotate, so that the pulley 18 on the outer wall drives the belt 19 to run, and then the pulley 18 on the outer wall of the adjacent secondary conveying roller 16 rotates synchronously, and then the secondary conveying roller 16 rotates and drives the outer wall gear 2 17 to rotate, thereby driving the adjacent meshing gear 2 17 to rotate, and the connected secondary conveying roller 16 rotates, so that under the transmission of the pulley 18, belt 19 and gear 2 17, multiple secondary conveying rollers 16 rotate synchronously to input the upper debris into the discharge port 26.

[0033] Please see attached Figure 4 The secondary crushing assembly includes a motor 29, the outer wall of the motor 29 is fixedly connected to the upper surface of the crushing tank 28, the driving end of the motor 29 is fixedly connected to a movable rod 30, the outer wall of the movable rod 30 is fixedly connected to multiple groups of cutting blades 31, the inner wall of the crushing tank 28 is fixedly connected to a T-shaped filter bucket 33, and the bottom of the movable rod 30 is rotatably connected to the middle of the T-shaped filter bucket 33.

[0034] Specifically, the motor 29 is started to make the multiple sets of cutting blades 31 crush and cut the debris. The cut debris falls into the top of the T-shaped filter 33 for screening. The debris particles that meet the crushing size will fall into the sewage pipe 34 for discharge, and those that do not meet the crushing size will continue to be crushed under the rotation of the multiple scrapers 32. By designing two crushing components, the lighter debris and heavier debris generated by separation can be crushed separately, thereby increasing the decomposition rate of the heavier debris in the septic tank, and the lighter debris can meet the passing conditions of the cam pump and be smoothly discharged into the septic tank.

[0035] Please see attached Figure 6 The primary crushing assembly includes two rotating shafts 10, the outer walls of the two rotating shafts 10 are rotatably connected to the inside of the crushing box 2, the upper surface of the crushing box 2 is fixedly connected with an inlet flange 8, the lower surface of the crushing box 2 is fixedly connected with an outlet flange 9, the other end of the inlet flange 8 is fixedly connected to the other end of the sewage guide pipe 3, the outer walls of the two rotating shafts 10 are fixedly connected with a plurality of crushing blades 13, the two groups of crushing blades 13 are staggered inside the crushing box 2, the outer walls of the two rotating shafts 10 are fixedly connected with gears 11, the outer walls of the two gears 11 are meshed and connected, and the end of one of the rotating shafts 10 is fixedly connected with a motor 12.

[0036] Specifically, the suspended foreign matter contained in the sewage will enter the crushing device with the water flow for crushing, and the motor 12 will be started to rotate the rotating shaft 10. Under the transmission of the two gears 11, the two rotating shafts 10 will rotate synchronously, driving the two sets of crushing blades 13 to rotate and crush the sewage entering the crushing box 2. The crushed sewage will be discharged into the next link through the outlet flange 9, meeting the technical conditions of the pass rate of the cam pump, without causing the pump to get stuck or the parts to be damaged, and can be smoothly discharged into the septic tank.

[0038] Specifically, during the crushing process, the movable rod 30 drives the plurality of scrapers 32 to move along the outer wall of the T-shaped filter hopper 33, thereby preventing the T-shaped filter hopper 33 from being blocked by impurities and affecting the subsequent filtering efficiency. In addition, the rotation of the plurality of scrapers 32 can cause the impurities to rise in the liquid, thereby preventing the unqualified impurities from being brought back into the plurality of cutting blades 31 for crushing.

[0039] Working principle: When the waste is processed, the waste enters the separation tank 1 from the waste inlet 4 for sedimentation. Through the isolation and blocking of the inclined plate 6 and the blocking plate 7, the fluid enters the lower part from the inlet and then is discharged upward from the sewage guide pipe 3 into the crushing box 2. At this time, the heavier foreign matter remains at the bottom of the separation tank 1 and the slag discharge pipe 5. The motor 12 is started to rotate the shaft 10. Under the transmission of the two gears 11, the two shafts 10 rotate synchronously, driving the two sets of crushing blades 13 to rotate and crush the waste entering the crushing box 2. The crushed waste is discharged from the outlet flange 9 to the next link. The heavier foreign matter will enter the separation box 14 through the slag discharge pipe 5. After being blocked by multiple lifting rods 24 and the blocking rod 25, the sundries that are not easy to separate, such as towels, can be left behind, while the smaller sundries will enter the inside of the guide pipe 27 for the next link. The motor 3 22 is started to drive the rotating rod 23 to drive the multiple lifting rods 24 to rotate. The larger soft debris left behind is carried to the conveying platform composed of multiple secondary conveying rollers 16 and the main driving roller 21. Under the conveying of the conveying platform, the debris is conveyed to the discharge port 26 and then collected for recycling. In the process of multiple lifting rods 24 lifting the debris, some of the debris will continue to be blocked by the blocking rod 25. After the debris on the conveying platform is conveyed away, the multiple lifting rods 24 continue to rotate through the middle gap of the conveying platform, and pass through the gaps between the multiple blocking rods 25 to lift the subsequent debris. This is repeated to complete the transmission of the debris. The smaller debris entering the guide pipe 27 will enter the crushing tank 28. At this time, the motor 29 is started to make the multiple groups of cutting blades 31 crush and cut it. The cut debris falls into the top of the T-shaped filter bucket 33 for screening. The debris particles that meet the crushing size will fall into the sewage pipe 34 for discharge, and those that do not meet the crushing size will continue to be crushed under the rotation of the multiple scrapers 32.
