Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a comprehensive wastewater and solid waste treatment device. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, the total discharge of various types of wastewater, such as oilfield wastewater, industrial wastewater, urban domestic sewage, and agricultural non-point source pollution, continues to rise. Solid waste, such as oilfield mining waste residue, domestic garbage, industrial solid waste, and hazardous waste, is also accumulating on a large scale. Moreover, various types of wastewater and solid waste are often intertwined, posing a great challenge to downstream wastewater and solid waste treatment.

[0003] In the comprehensive treatment process involving both wastewater and solid waste, solid waste pretreatment is the core link that determines the overall treatment efficiency and resource utilization effectiveness. Crushing, in particular, breaks down large pieces of solid waste into smaller particles, effectively increasing the specific surface area of ​​the solid waste. This not only creates favorable conditions for subsequent solid waste treatment processes such as fermentation degradation and resource recovery, but also enables preliminary solid-liquid separation through the screens within the crushing device. The separated liquid portion is then simultaneously introduced into the wastewater treatment system, laying the foundation for comprehensive collaborative treatment. Currently, the industry widely uses integrated comprehensive treatment devices that combine crushing, fermentation, separation, and wastewater purification. These devices achieve comprehensive treatment by integrating core functions such as solid waste crushing, high-temperature fermentation, product packaging and separation, and anaerobic-anoxic-aerobic staged purification of wastewater.

[0004] However, while current integrated processing devices achieve the integration of multiple processes, during the crushing process, solid waste is usually crushed directly through the crushing chamber. However, the solid waste may still contain stubborn materials that are not easy to crush, such as plastic film. The composting degradation time of these stubborn materials varies greatly, especially for stubborn materials containing residual petroleum and other oils, which are more difficult to crush and degrade. As a result, the products of direct crushing and fermentation will still contain these stubborn materials, which will cause secondary pollution to the soil, crops and ecological environment when the fermentation products are used for resource utilization such as composting. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a wastewater and solid waste comprehensive treatment device and its forging process, which aims to solve the problem that in the prior art, the wastewater and solid waste comprehensive treatment device directly crushes the waste material during the treatment of waste, resulting in the presence of plastic film in the subsequent fermentation and compost, which causes environmental pollution during subsequent use.

It includes a bracket located outside the material guiding component, a drive component located on the bracket, and a rejection component connected to the drive component. The drive component is used to drive the rejection component to move back and forth, up and down, and rotate. The material guiding component includes a hopper and a rotatable baffle plate disposed inside the hopper, and the rejection component includes a rotating roller and a piercing rod disposed on the transmission roller.

[0007] In addition, the wastewater and solid waste comprehensive treatment device according to the above embodiments of the present invention may also have the following additional technical features: Furthermore, the driving component includes a first driving member, a vertical plate connected to the first driving member, a horizontal plate slidably connected to the vertical plate, and longitudinal plates disposed on both sides of the horizontal plate. The rotating roller is rotatably connected to the horizontal plate, and the longitudinal plates are fixed on the bracket. The bottom of the horizontal plate and the top of the longitudinal plate are provided with mutually adapted arc block portions. The first driving member is used to drive the vertical plate to move back and forth.

[0008] Furthermore, the longitudinal plate is provided with a rack on its side, the horizontal plate is provided with a vertical rod rotatably connected to the horizontal plate at its bottom, the vertical rod is provided with a gear adapted to the rack at its bottom, and both the rotating roller and the vertical rod are provided with a synchronous pulley connected by a synchronous belt.

[0009] Furthermore, the rejection component includes a fixed ring disposed on the rotating roller, an arc-shaped plate located below the fixed ring and sleeved on the rotating roller, and a second driving member disposed on the fixed ring and connected to the arc-shaped plate via a connecting rod. The arc-shaped plate is provided with a clearance groove for avoiding the piercing rod, and the second driving member is used to drive the arc-shaped plate closer to or away from the rotating roller.

[0010] Furthermore, the rejection assembly includes a third driving member disposed on the horizontal plate, a transmission rod connected to the third driving member, and a cutting blade connected to the transmission rod. The cutting blade is located on both sides of the rotating roller, and the horizontal plate is provided with clearance holes adapted to the cutting blade. There is clearance space between the body of the cutting blade and the rotating roller to avoid the second driving member and the connecting rod. The third driving member is used to drive the transmission rod to move up and down.

[0011] Furthermore, the bottom of the cutting blade is provided with an L-shaped blade, the horizontal part of the L-shaped blade is connected to the bottom of the cutting blade, and the vertical part of the L-shaped blade is in contact with the outer contour of the arc plate.

[0012] Furthermore, the wastewater and solid waste comprehensive treatment device also includes a dredging component, which includes a dredging part and a steel wire rope disposed in the material guiding component. One end of the steel wire rope is connected to the dredging part, and the other end is connected to one side of the barrier plate. The hopper has a fourth driving component connected to the barrier plate, which is used to drive the barrier plate to rotate.

[0013] Furthermore, the unblocking component includes a gravity column, a guide ring sleeved on the outside of the gravity column, a support rod connecting the guide ring and the gravity column, and a pressing rod disposed on the side of the gravity column and rotatably connected to the gravity column. An elastic element is provided between the pressing rod and the gravity column, and a limiting element is provided at the top of the gravity column. The limiting element is used to limit the included angle between the pressing rod and the gravity column.

[0015] Furthermore, multiple puncture rods are evenly distributed on the rotating roller, and there is an angle between the puncture rods and the rotating roller, so that the bottom of the puncture rods is inclined downward on the rotating roller.

[0016] This invention, by installing a rejection component above the crushing assembly within the crushing chamber, allows the waste material to be crushed to first be placed on the baffle plate of the guide hopper of the guiding component. Then, a drive component drives the rejection component to move back and forth, up and down, and rotate, causing the piercing rod on the transmission roller to move upwards and then downwards, piercing the waste material. Further rotation causes plastic film to wrap around the rotating roller. The transmission roller is then driven to move the plastic film upwards and forwards a certain distance, then downwards, causing the piercing rod to pierce the plastic film in a new area. This process is repeated to clean the plastic film from all baffle plates. After cleaning, the baffle plates are flipped, allowing the waste material without plastic film to pass through the guide component into the crushing assembly for crushing. The baffle plates are then reset after flipping, and the plastic film wrapped around the rejection component is removed, preparing for the next batch of waste material to be cleaned. Therefore, this invention solves the problem in existing wastewater and solid waste comprehensive treatment devices where direct crushing of waste leads to the presence of plastic film in subsequent fermentation and composting, causing environmental pollution during subsequent use.

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the invention will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1 to 7The image shows a wastewater and solid waste comprehensive treatment device according to an embodiment of the present invention, comprising: a device body 10 for providing a supporting and accommodating space, the device body 10 having a crushing chamber 11; a crushing component 20 disposed in the crushing chamber 11 for crushing waste materials, including a crushing part 21 and a guiding part 22 disposed on the crushing part 21; and a rejection component 30 disposed in the crushing chamber 11 outside the guiding part 22, including a support 31 disposed outside the guiding part 22, a driving part 32 disposed on the support 31, and a rejection part 33 connected to the driving part 32, the driving part 32 being used to drive the rejection part 33 to move back and forth, up and down, and rotate. The material guiding component 22 includes a hopper 221 and a rotatable baffle plate 222 disposed inside the hopper 221, and the rejection component 33 includes a rotating roller 331 and a piercing rod 332 disposed on the transmission roller.

[0023] Understandably, by setting a rejection component 30 above the crushing component 20 in the crushing chamber 11, the waste to be crushed is first placed on the baffle plate 222 of the guide hopper 221 of the guide component 22. Then, the drive component 32 drives the rejection component 33 to move back and forth, up and down, and rotate, so that the piercing rod 332 on the transmission roller moves upward and then downward to pierce the waste in the waste. Then it rotates, so that the plastic film is wrapped around the rotating roller 331. Then the drive roller drives the plastic film to move upward and then forward a certain distance, and then moves downward so that the piercing rod 332 pierces the plastic film in the new area. The above steps are repeated to clean the plastic film on all the baffle plates 222. After cleaning, the baffle plates 222 are controlled to flip, so that the waste without plastic film after cleaning passes through the guide component 22 into the crushing component 20 for crushing. After the baffle plates 222 are flipped and reset, the plastic film wrapped around the rejection component 33 is cleaned and removed to prepare for the plastic film cleaning of the next batch of waste. Therefore, this invention solves the problem in existing wastewater and solid waste comprehensive treatment devices that directly crush waste materials during processing, resulting in plastic film in the subsequent fermentation and composting, which causes environmental pollution during subsequent use. It should be noted that the main body 10 of the device also includes a fermentation chamber 12 and a sedimentation tank 13 to treat the crushed waste materials, thereby realizing the comprehensive wastewater and solid waste treatment function of the device.

[0024] Specifically, the driving component 32 includes a first driving member 321, a vertical plate 322 connected to the first driving member 321, a horizontal plate 323 slidably connected to the vertical plate 322, and longitudinal plates 324 disposed on both sides of the horizontal plate 323. A rotating roller 331 is rotatably connected to the horizontal plate 323. The longitudinal plates 324 are fixed on the bracket 31. The bottom of the horizontal plate 323 and the top of the longitudinal plates 324 are provided with mutually adaptable arc block portions 325. The first driving member 321 is used to drive the vertical plate 322 to move back and forth. In a specific implementation, the first driving member 321 drives the vertical plate 322 to move forward, thereby the vertical plate 322 drives the horizontal plate 323 to move forward. This causes the arc block portions 325 on the horizontal plate 323 to cooperate with the arc block portions 325 on the longitudinal plate 324, so that the horizontal plate 323 moves forward and simultaneously moves up and down, thereby driving the piercing rod 332 on the horizontal plate 323 to move up and down, achieving the piercing effect. In addition, the top of the longitudinal plate 324 is provided with multiple arc-shaped blocks 325 to allow the piercing rod 332 to move up and down continuously. The diameter of the arc-shaped blocks 325 needs to be no greater than the diameter of the rotating roller 331 so that the range of each piercing by the piercing rod 332 has a certain overlap, so as to avoid the range being too far apart when two piercings are performed, which would result in the plastic film between the two piercing ranges not being collected and removed, thus ensuring the cleaning effect of the plastic film.

[0025] Additionally, the longitudinal plate 324 has a rack 3241 on its side, and the bottom of the transverse plate 323 has a vertical rod 326 rotatably connected to the transverse plate 323. The bottom of the vertical rod 326 has a gear 327 adapted to the rack 3241. Both the rotating roller 331 and the vertical rod 326 are equipped with synchronous pulleys 329 connected by a synchronous belt 328. In practice, the rack 3241 on the outer side of the longitudinal plate 324 engages with the gear 327, allowing the vertical rod 326 to drive the rotating roller 331 to rotate while moving back and forth via the synchronous pulleys 329 and the synchronous belt 328. This ensures the punctured plastic film wraps around the rotating roller 331, guaranteeing effective collection and cleaning of the plastic film. This design requires fewer drive components and is less costly than using multiple separate drive components to drive the rotating roller 331 to rotate, move up and down, and move back and forth. Understandably, this design requires multiple arc-shaped blocks 325 and racks 3241, as well as adjustments to the dimensions of the arc-shaped blocks 325 and the length of the racks 3241, to ensure that the effective areas of adjacent piercing and rotating winding processes overlap, thus preventing the plastic film from being missed and ensuring the cleaning effect. Furthermore, in practical implementation, multiple rotating rollers 331 can be set up. These rollers 331 cooperate with a synchronous belt 328 via a synchronous pulley 329, allowing a single power source to simultaneously drive multiple rollers 331 to move together. The multiple rollers 331 cooperate with each other to ensure sufficient coverage of the cleaning area and guarantee the cleaning effect of the plastic film. Further, the top of the hopper 221 can be set into a rectangular shape to cooperate with the multiple rotating rollers 331, ensuring the coverage and cleaning effect of the multiple rotating rollers 331 and avoiding motion interference between the top of the circular hopper 221 and the outer rotating rollers 331.

[0026] Specifically, the rejection component 33 includes a fixing ring 334 mounted on the rotating roller 331, an arc-shaped plate 335 sleeved on the rotating roller 331 below the fixing ring 334, and a second driving member 336 mounted on the fixing ring 334 and connected to the arc-shaped plate 335 via a connecting rod 3351. The arc-shaped plate 335 has a clearance groove 3352 for avoiding the piercing rod 332. The second driving member 336 drives the arc-shaped plate 335 to move closer to or away from the rotating roller 331. In a specific implementation, the second driving member 336 drives the connecting rod 3351 away from the rotating roller 331, causing the connecting rod 3351 to drive the arc-shaped plate 335 away from the rotating roller 331. As a result, the arc-shaped plate 335 pushes the plastic film on the piercing rod 332 outward, so that the plastic film is removed from the rejection component 30, ensuring the piercing and wrapping effect of the subsequent piercing rod 332 on the plastic film, thereby ensuring the removal efficiency and effect of the plastic film.

[0027] Additionally, the rejection assembly 30 includes a third drive member 337 disposed on the horizontal plate 323, a transmission rod 3371 connected to the third drive member 337, and a cutting blade 338 connected to the transmission rod 3371. The cutting blade 338 is located on both sides of the rotating roller 331, and the horizontal plate 323 is provided with clearance holes 3231 adapted to the cutting blade 338. There is clearance space between the main body of the cutting blade 338 and the rotating roller 331 to avoid the second drive member and the connecting rod 3351. The third drive member 337 is used to drive the transmission rod 3371 to move up and down. In practical implementation, when the rotating roller 331 has finished rotating and the plastic film on the arc-shaped plate 335 needs to be removed and cleaned, the third driving component 337 drives the transmission rod 3371 to move downwards. This causes the transmission rod 3371 to drive the cutting blade 338 downwards to cut the plastic film on the outer contour of the arc-shaped plate 335, preventing the plastic film on the outer contour of the arc-shaped plate 335 from getting caught on each other. This makes it easier and faster for the second driving component 336 to drive the arc-shaped plate 335 outwards, thereby improving the cleaning efficiency of the plastic film on the arc-shaped plate 335. In addition, by adjusting the distance between the cutting blade 338 and the rotating roller 331, sufficient space is provided to avoid the second driving component 336 and the connecting rod 3351 driven by the rotating roller 331.

[0028] Specifically, the bottom of the cutting disc 338 is provided with an L-shaped blade 339. The horizontal portion 3391 of the L-shaped blade 339 is connected to the bottom of the cutting disc 338, and the vertical portion 3392 of the L-shaped blade 339 is in contact with the outer contour of the arc plate 335. In specific implementation, by setting the L-shaped blade 339, the bottom of the L-shaped blade 339 is in contact with the outer contour of the arc plate 335, while avoiding the second driving member 336 and the connecting rod 3351. After the rotating roller 331 has rotated, the movement of the cutting disc 338 is guided by the contact point of the L-shaped blade 339, and the plastic film is partially tilted outward, so that the cutting disc 338 is located inside the plastic film to cut the plastic film, thereby ensuring the cutting effect of the plastic film and preventing the plastic film from getting caught on the outside of the arc plate 335.

[0029] Additionally, the wastewater and solid waste comprehensive treatment device also includes a dredging component 40. The dredging component 40 includes a dredging part 41 and a steel wire rope 42 disposed within the material guiding component. One end of the steel wire rope 42 is connected to the dredging part 41, and the other end is connected to one side of the baffle plate 222. A fourth driving component 223 connected to the baffle plate 222 is located on the hopper 221, and the fourth driving component 223 drives the baffle plate 222 to rotate. In specific implementation, when the waste on the baffle plate 222 has had its plastic film removed, the fourth driving component 223 drives the baffle plate 222 to rotate, causing the waste to fall into the hopper 221. The rotation of the baffle plate 222 also causes the dredging part 41 to move, allowing it to move up and down within the material guiding pipe 224 below the hopper 221 to avoid potential blockages in the material guiding pipe 224 and ensure efficient waste transfer.

[0030] Specifically, the unblocking component 41 includes a gravity column 411, a guide ring 412 sleeved on the outside of the gravity column 411, a support rod 413 connecting the guide ring 412 and the gravity column 411, and a pressure rod 414 disposed on the side of the gravity column 411 and rotatably connected to the gravity column 411. An elastic element 415 is provided between the pressure rod 414 and the gravity column 411, and a limiting element 416 is provided at the top of the gravity column 411. The limiting element 416 is used to limit the included angle between the pressure rod 414 and the gravity column 411. In practical implementation, when the baffle plate 222 rotates and waste begins to enter the guide pipe 224 under the hopper 221, the unblocking component 41 moves upward, the waste moves downward, and squeezes the pressure rod 414, causing the pressure rod 414 to approach the gravity column 411. This prevents the pressure rod 414 from continuously opening and obstructing the movement of the waste, ensuring the efficiency of waste transfer. After dumping is completed, the baffle plate 222 resets. At this time, the baffle plate 222 no longer pulls the steel wire rope 42 upward. Under the gravity of the gravity column 411, the unblocking component 41 moves downward as a whole and performs a stable vertical movement under the action of the guide ring 412 to squeeze and push any blockage waste in the pipe, thereby clearing the blockage in the guide pipe 224. In addition, at this time, the pressure rod 414 opens at a certain angle under the restoring force of the elastic element 415 to increase the working area of ​​the unblocking component 41, thereby improving the unblocking effect of the unblocking component 41. Furthermore, the opening angle of the pressure rod 414 is controlled by an additional limiting component 416. This ensures that the opening angle of the pressure rod 414 is large enough to expand the effective area of ​​the unblocking component 41, while preventing the pressure rod 414 from interfering with the guide pipe 224 due to an excessively large opening angle, thus affecting the unblocking effect of the unblocking component 41. In addition, in specific implementation, the unblocking component 41 can be located near the hopper 221 on the guide pipe 224. When the baffle plate 222 rotates and the waste on the baffle plate 222 is dumped, the unblocking component 41 is located inside the hopper 221. This avoids the additional unblocking component 41 encroaching on the space inside the guide pipe 224, which would make the waste inside the guide pipe 224 more prone to blockage than when no structure is provided. Even though the unblocking component 41 somewhat obstructs the flow of waste material within the hopper 221, the hopper 221 is conical in shape and large enough to prevent blockage in the area where the unblocking component 41 is located. Furthermore, the rotatable downward pressure rod 414 on the unblocking component 41 also reduces the obstruction effect on waste material flow to some extent. In addition, by placing the unblocking component 41 on the hopper 221, the flow of some waste material is somewhat obstructed, resulting in a longer flow time and a more uniform flow rate across different time periods. This avoids excessive waste flow at any given time, which could lead to blockage in the guide pipe 224.

[0031] Additionally, the support frame 31 includes a transverse frame portion 311 connected to the crushing chamber 11, auxiliary support portions 312 disposed on both sides of the hopper 221 and connected to the transverse frame portion 311, and a vertical connecting portion 313 for connecting the auxiliary support portions 312 and the longitudinal plate 324. In a specific implementation, the support frame 31 is fixed as a whole within the crushing chamber 11 by the transverse frame portion 311, and the longitudinal plate 324 is fixed above the hopper 221 by the auxiliary support plates and the vertical connecting portion 313, which cooperate with the transverse plate 323 on both sides.

[0032] Specifically, multiple piercing rods 332 are evenly distributed on the rotating roller 331, with an angle between the piercing rods 332 and the rotating roller 331, so that the bottom of the piercing rods 332 is inclined downwards on the rotating roller 331. In practical implementation, by setting multiple evenly distributed piercing rods 332, the rejection and cleaning effect of the plastic film is ensured, and the angle of the piercing rods 332 is adjusted to determine their range of action, so as to match the dimensions of the rack 3241 and the arc block 325, thereby ensuring the rejection and cleaning effect of the plastic film.

[0033] In summary, this invention, by setting a rejection component 30 above the crushing component 20 in the crushing chamber 11, allows the waste material to be crushed to first be placed on the baffle plate 222 of the guide hopper 221 of the guide component 22. Then, the drive component 32 drives the rejection component 33 to move back and forth, up and down, and rotate, causing the piercing rod 332 on the transmission roller to move upward and then downward to pierce the waste material. Then, it rotates, causing the plastic film to wrap around the rotating roller 331. The drive roller then drives the plastic film to move upward and then forward a certain distance, and then downward so that the piercing rod 332 pierces the plastic film in the new area. The above steps are repeated to clean the plastic film on all the baffle plates 222. After cleaning, the baffle plates 222 are flipped so that the waste material without plastic film after cleaning passes through the guide component 22 and is crushed in the crushing component 20. After the baffle plates 222 are flipped and reset, the plastic film wrapped around the rejection component 33 is cleaned and removed to prepare for the cleaning of the plastic film of the next batch of waste material. Therefore, the present invention solves the problem that in the prior art, wastewater and solid waste comprehensive treatment devices directly crush waste materials during waste treatment, resulting in the presence of plastic film in subsequent fermentation and composting, which causes environmental pollution during subsequent use.
