[0002] Sewage treatment refers to the process of purifying sewage to make it meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc. Sewage treatment mainly includes two processes: pretreatment and deep treatment. Pretreatment mainly discharges particulate matter in sewage, and deep treatment mainly aerates, oxidizes and disinfects sewage.

[0003] In the sewage pretreatment process, solid-liquid separation as a key process is mainly achieved through centrifugal separation equipment. When treating sewage containing large-sized solid waste, the centrifugal force generated by high-speed rotation may cause abnormal accumulation of solid particles inside the equipment. This physical blockage will not only reduce the separation efficiency, but may also cause the system to shut down for maintenance, which may affect the stability of the entire pretreatment process.

[0004] Therefore, the utility model provides a waste liquid pretreatment device with a classification collection function to solve the above problems. Utility Model Content

[0027] 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.

[0028] The utility model provides a waste liquid pretreatment device with a classification collection function, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the waste liquid pretreatment device includes a bottom plate 1, support legs 2 fixedly mounted on the bottom plate 1, a treatment cylinder 3 fixedly mounted on the support legs 2, a top plate 4 arranged on the treatment cylinder 3, a separation cylinder 5 fixedly mounted on the top plate 4, and a centrifugal mechanism arranged inside the separation cylinder 5 for performing solid-liquid separation on the sewage.

[0029] The centrifugal mechanism includes a screening cover 6 fixedly installed inside the separation cylinder 5, a centrifugal tube 7 rotatably installed inside the separation cylinder 5, a motor 8 fixedly installed on the top of the separation cylinder 5, a centrifugal mesh cylinder 9 fixedly installed inside the separation cylinder 5, a crushing disk 10 fixedly installed on the centrifugal tube 7, a crushing knife 11 fixedly installed on the crushing disk 10, an inclined bucket 12 fixedly installed inside the separation cylinder 5, and a plurality of water outlet holes 13 opened inside the top plate 4.

[0030] The top of the centrifuge tube 7 passes through the screening cover 6 and the separation cylinder 5 in sequence.

[0031] The output end of the motor 8 is fixedly connected to one end of the centrifugal tube 7 , and the crushing disc 10 is arranged between the screening cover 6 and the centrifugal net cylinder 9 .

[0032] When the waste liquid pretreatment device is in use, the sewage is first added into the interior of the separation cylinder 5 through the feed pipe at the top of the separation cylinder 5, and the sewage first contacts the screening cover 6. The liquid and small solids will enter the interior of the centrifugal screen cylinder 9 through the discharge hole on the screening cover 6, and the larger solids will enter the position between the screening cover 6, the separation cylinder 5 and the inclined bucket 12. Then, by starting the motor 8, the output shaft of the motor 8 drives the centrifugal tube 7 fixedly connected thereto to rotate synchronously, so that the sewage inside the centrifugal screen cylinder 9 is thrown out, and the impurities in the sewage are filtered by the centrifugal screen cylinder 9. The water will be thrown to the position between the centrifugal screen cylinder 9 and the separation cylinder 5, and then enter the treatment cylinder 3 through the water outlet hole 13. At the same time, the rotation of the centrifuge tube 7 drives the pulverizing disk 10 fixedly connected thereto to rotate synchronously, and the rotation of the pulverizing disk 10 drives multiple pulverizing knives 11 fixedly connected thereto to rotate synchronously, and the solids screened by the screening cover 6 are crushed by the pulverizing knives 11 until they are crushed to a position with the same size of the holes on the screening cover 6, and then enter the interior of the centrifugal net cylinder 9 through the holes on the side of the screening cover 6, and then the solid-liquid separation is completed through the centrifuge tube 7, thereby completing the classification and collection, wherein the abnormal accumulation of larger volume solid particles inside the equipment is reduced, the efficiency of solid-liquid separation is improved, and the stability of the entire pretreatment process is improved.

[0033] Furthermore, in order to facilitate the pretreatment of sewage, e.g. Figure 1 , Figure 2 and Figure 4 As shown, a feed opening 14 is provided inside the top plate 4 , and the feed opening 14 is arranged just below the centrifugal net cylinder 9 .

[0034] An electric push rod 15 is fixedly connected to the inner wall of the processing cylinder 3, and a baffle 16 is fixedly connected to the movable end of the electric push rod 15.

[0035] The top of the baffle 16 fits with the bottom of the top plate 4 , and a neutralization probe 17 is fixedly connected to the bottom of the top plate 4 .

[0036] A neutralization nozzle 18 is fixedly connected to the interior of the treatment cylinder 3 , and a feed pipe 19 is fixedly connected to the bottom of the treatment cylinder 3 .

[0037] When the waste liquid pretreatment device is in use, the water separated into the treatment cylinder 3 will be detected by the neutralization probe 17, and then the water will be neutralized by the neutralization nozzle 18 until it meets the standard, and then it will be discharged through the discharge pipe 19. When it is necessary to clean the solids remaining in the centrifugal net cylinder 9, the electric push rod 15 is started, and the movable end of the electric push rod 15 drives the two baffles 16 to move outward synchronously. Through the movement of the baffle 16 and the cooperation between the discharge port 14, the treatment cylinder 3 and the separation cylinder 5 are connected, and the solids inside the centrifugal net cylinder 9 enter the interior of the treatment cylinder 3 through the discharge port 14, and then they are discharged through the discharge pipe 19, thereby completing the pretreatment of them.

[0038] Furthermore, in order to facilitate the connection between the treatment cylinder 3 and the separation cylinder 5, as Figure 1 , Figure 2 and Figure 6 As shown, a roller 20 is rotatably connected inside the support leg 2 , a threaded rod 21 is fixedly connected to the side surface of the roller 20 , and a threaded block 22 is screwed to the side surface of the threaded rod 21 .

[0039] When the waste liquid pretreatment device is in use, the top plate 4 and the separation cylinder 5 are placed on the top of the treatment cylinder 3, and the threaded rod 21 is manually turned to drive the roller 20 and the threaded rod 21 to rotate until the threaded rod 21 moves into the groove on the top plate 4. Then, the threaded block 22 is inserted into the threaded rod 21, and the threaded block 22 is rotated until the bottom of the threaded block 22 fits against the top of the top plate 4 to fix the top plate 4, thereby completing the connection between the treatment cylinder 3 and the separation cylinder 5.
