Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a solid-liquid separation type sewage treatment equipment. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering.

[0003] The patent with patent number CN215901030U discloses a solid-liquid separation system for sewage treatment, which belongs to the field of sewage treatment equipment. The solid-liquid separation system for sewage treatment consists of a primary filter tank and a secondary filter tank. The sewage is filtered through the primary filter tank and then enters the secondary filter tank for filtration. A primary filter plate is arranged inside the primary filter tank. The plate body of the primary filter plate itself is a mesh structure. A baffle is arranged on the left side of the plate body. The baffle can block larger solid waste, and the plate body can filter smaller solid waste. A secondary filter plate is arranged inside the secondary filter tank, and the secondary filter plate can filter the sewage again. The invention can effectively separate the solid and liquid of the sewage to ensure that the subsequent sewage treatment process can proceed smoothly.

[0004] When the above device filters sewage, solid waste in the sewage will accumulate in the primary filter tank and the secondary filter tank. When the solid waste in the filter tank accumulates too much, it will be blocked at the filter plate, thereby affecting the filtration efficiency. When cleaning, workers need to manually or operate equipment to remove the solid waste inside the filter tank, and the cleaning effect is poor and the cleaning speed is slow.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: A solid-liquid separation type sewage treatment equipment, such as Figure 1-Figure 16As shown, it includes an inlet channel 1, an outlet channel 101, a debris recovery frame 102, a connecting frame 103, a fixed filter plate 2, a double-axis motor 201, a driving gear 202, a rotating filter cartridge 203, a transmission gear 204, a debris collection mechanism and a cleaning mechanism. The inlet channel 1 is connected to the outlet channel 101 through the connecting frame 103. The debris recovery frame 102 is fixedly connected to the outlet channel 101. A fixed filter plate 2 is installed in the inlet channel 1. The filter holes on the fixed filter plate 2 correspond to the inlet of the connecting frame 103. The double-axis motor 201 is installed on one side of the outlet channel 101. A driving gear 202 is fixedly connected to the output shaft, a rotary filter cartridge 203 is rotatably connected in the outlet channel 101, a transmission gear 204 is fixedly connected to the outside of the rotary filter cartridge 203, the driving gear 202 is meshed with the transmission gear 204, the dual-axis motor 201 can drive the transmission gear 204 and the rotary filter cartridge 203 to rotate through the driving gear 202, a debris collecting mechanism is installed at the inlet channel 1, the debris collecting mechanism is used to transport the debris in front of the fixed filter plate 2 to the outside, and a cleaning mechanism is installed in the rotary filter cartridge 203, the cleaning mechanism is used to clean the sediment in the rotary filter cartridge 203.

[0040] During the filtering process, the dual-axis motor 201 will drive the transmission gear 204 and the rotating filter cylinder 203 to rotate through the driving gear 202, and the sewage will flow in from the water inlet channel 1. Then, when the sewage flows to the fixed filter plate 2, the agglomerated sand and gravel in the sewage are blocked by the fixed filter plate 2, and the water flow carries the silt through the fixed filter plate 2 and the connecting frame 103 and flows into the rotating filter cylinder 203. During the rotation of the rotating filter cylinder 203, the water flow inside it flows outward from the filter holes on the rotating filter cylinder 203 along the water outlet channel 101, and the silt in the water remains in the rotating filter cylinder 203. The cleaning mechanism will clean the silt in the rotating filter cylinder 203 and send it out. The debris collection mechanism will collect the agglomerated sand and gravel separated by the fixed filter plate 2 in the water inlet channel 1 and send it out, and the water in the agglomerated sand and gravel can be depressurized during the transportation process to achieve the function of separating solid debris in the sewage and automatically removing it from the equipment.

[0041] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 3-Figure 8As shown, the debris collection mechanism includes a storage frame 2001, a scraper rod 2002, a first missing gear 2041, a second missing gear 2042, a winding shaft 205, a winding gear 206, a pull rope 207, a guide wheel 208 and a water pressure assembly. The storage frame 2001 is slidably connected in the water inlet 1. The bottom surface of the storage frame 2001 is an inclined surface. A friction pad is arranged in the slideway in the water inlet 1. When the storage frame 2001 slides downward along the water inlet 1, the friction pad can reduce the speed at which the storage frame 2001 slides downward, and the bottom surface of the storage frame 2001 is inclined in the direction of the fixed filter plate 2, so as to facilitate the collection of debris in the sewage. A scraper rod 2002 is fixedly connected in the storage frame 2001. The scraper rod 2002 is in contact with the fixed filter plate 2. When the scraper rod 2002 moves, the debris adhered to the surface of the fixed filter plate 2 is scraped off. A first missing gear 2041 is fixedly connected to the moving gear 204, a second missing gear 2042 is fixedly connected to the first missing gear 2041, the first missing gear 2041, the second missing gear 2042 and the transmission gear 204 are coaxially fixedly connected, a winding shaft 205 is symmetrically connected to the outside of the water inlet 1 for rotation, a winding gear 206 is fixedly connected to the outside of the winding shaft 205, the two winding gears 206 are respectively meshed with the first missing gear 2041 and the second missing gear 2042, a guide wheel 208 is rotatably connected to the water inlet 1, a pull rope 207 is fixedly connected to the winding shaft 205, the pull rope 207 is fixedly connected to the storage frame 2001 after passing around the guide wheel 208, the water pressure component is installed outside the water inlet 1, the water pressure component will provide pressure to the debris in the debris collection mechanism to depressurize the water in the debris inside it.

[0042] When the sewage cleaned of silt flows along the inlet channel 1 and passes through the fixed filter plate 2, the agglomerated sand and gravel in the sewage will be blocked by the fixed filter plate 2. At this time, the agglomerated sand and gravel will be in the storage frame 2001 and will slide along the inner bottom surface of the storage frame 2001 to the fixed filter plate 2. When the dual-axis motor 201 drives the transmission gear 204 to rotate through the active gear 202, the first missing gear 2041 and the second missing gear 2042 rotate synchronously with the transmission gear 204. The first missing gear 2041 and the second missing gear 2042 both have half a circle of teeth, and the positions of the teeth on the first missing gear 2041 and the second missing gear 2042 are staggered. The winding gear 206 on the two winding shafts 205 on both sides of the inlet channel 1 are respectively connected to the first missing gear 2041 and the second missing gear 2 042 cooperates, and during the rotation of the first missing gear 2041 and the second missing gear 2042, the teeth on the outside of the two winding gears 206 are meshed at the same time, so that the first missing gear 2041 and the second missing gear 2042 simultaneously drive the two winding gears 206 to rotate, and then drive the winding shaft 205 to rotate. When the winding shaft 205 rotates, it can pull the storage frame 2001 to slide upward along the slideway on the water inlet channel 1 through the pull rope 207, and the pull rope 207 is wound on the winding shaft 205. During the rising process of the storage frame 2001, the sand and gravel accumulated inside the storage frame 2001 will be transported upward accordingly, and during the rising process of the storage frame 2001, since the storage frame 2001 is in contact with the fixed filter plate 2, the scraper rod 2002 will move its outer surface upward along the fixed filter plate 2. The sand and other debris remaining on the wall of the storage frame 2001 are scraped off to prevent the sand and other debris in the sewage from clogging the filter holes on the fixed filter plate 2. During the rising process of the storage frame 2001, the water pressure component will come into contact with the sand and gravel and other debris inside it, and as the storage frame 2001 continues to rise, the water pressure component will compact the sand and gravel in the storage frame 2001 and press out the residual water in the sand and gravel. The water pressed out of the sand and gravel by the water pressure component will be discharged downward from the drainage hole at the bottom of the storage frame 2001. When the storage frame 2001 rises to the highest point, the sand and gravel in the storage frame 2001 will slide into the debris recovery frame 102 along the inclined surface at its bottom. At this time, the teeth on the first missing gear 2041 and the second missing gear 2042 are out of contact with the winding gear 206. At this time, under the action of gravity, the storage frame 200 1 will slide downward along the water inlet channel 1 and pull the winding shaft 205 to rotate through the pull rope 207. As the winding shaft 205 continues to rotate, the pull rope 207 will be wound around the winding shaft 205. During the descent of the storage frame 2001, the friction pad in the slideway of the water inlet channel 1 will provide a certain obstacle for the storage frame 2001 to prevent the storage frame 2001 from descending too fast. After the storage frame 2001 descends and resets, it continues to collect the agglomerated sand and gravel blocked by the fixed filter plate 2. As the dual-axis motor 201 continues to run, under the action of the first missing gear 2041, the second missing gear 2042 and the winding gear 206, the storage frame 2001 intermittently slides up and down along the water inlet channel 1 to regularly discharge the agglomerated sand and gravel blocked by the fixed filter plate 2 in the water inlet channel 1.

[0043] Embodiment 3: Based on embodiment 2, Figure 1 and Figure 6-Figure 8 As shown, the water pressure assembly includes an L-shaped plate 3, a vertical guide rod 301, a downward pressure spring 302, a swing pressure plate 303, a limit rod 304, a limit rotating shaft 305, a reset torsion spring 306 and a connecting slide plate 307. The L-shaped plate 3 is fixedly connected to the outside of the water inlet 1, the vertical guide rod 301 is fixedly connected to the L-shaped plate 3, the vertical guide rod 301 is slidably connected to the connecting slide plate 307, a downward pressure spring 302 is arranged between the connecting slide plate 307 and the vertical guide rod 301, the downward pressure spring 302 is sleeved outside the vertical guide rod 301, one end of the downward pressure spring 302 is fixed to the vertical guide rod 301, and the other end is fixed to the connecting slide plate On 307, the connecting slide 307 is rotatably connected to the limiting shaft 305, the limiting shaft 305 is fixedly connected to the swinging pressure plate 303, and the limiting rod 304 is fixedly connected to the L-shaped plate 3. The limiting rod 304 passes through the connecting slide 307 and the limiting shaft 305 and extends upward. Under the restriction of the limiting rod 304, the swinging pressure plate 303 cannot swing upward. A reset torsion spring 306 is provided between the swinging pressure plate 303 and the connecting slide 307. The reset torsion spring 306 is a bidirectional torsion spring, one end of which is fixed on the connecting slide 307, and the other end is fixed on the swinging pressure plate 303.

[0044] During the rising process of the storage frame 2001, the swing pressure plate 303 will come into contact with the sand and gravel agglomerated in the storage frame 2001. At this time, since the swing pressure plate 303 and the connecting slide plate 307 are pressed at the lowest point of the limit rod 304 by the downward pressure spring 302, the swing pressure plate 303 and the limit rotating shaft 305 are restricted by the downward pressure spring 302 and cannot rotate upward. The storage frame 2001 continues to rise, which will push the swing pressure plate 303, the limit rotating shaft 305, the return torsion spring 306 and the connecting slide plate 307 to rise, and the downward pressure spring 302 is compressed. 302 is continuously compressed, and the pressure provided by the connecting slide plate 307 to the sand and gravel agglomerated in the storage frame 2001 through the swinging pressure plate 303 gradually increases, so as to press out the water contained in the sand and gravel agglomerated in the storage frame 2001, and the pressed water will be discharged downward from the drainage hole at the bottom of the storage frame 2001 into the water inlet channel 1. When the swinging pressure plate 303 and the limiting rotating shaft 305 rise and are out of contact with the limiting rod 304, the limiting rotating shaft 305 is no longer restricted by the limiting rod 304, and the storage frame 2001 continues to rise, which will push the swinging pressure plate 303 and The limit shaft 305 swings upward around the connecting slide 307, and the reset torsion spring 306 accumulates force and deforms. When the swing pressure plate 303 rotates upward until it is out of contact with the storage frame 2001, under the action of the reset torsion spring 306, the swing pressure plate 303 and the limit shaft 305 rotate and reset around the connecting slide 307. At this time, the through hole on the limit shaft 305 is aligned with the limit rod 304 again. At this time, the limit rod 304 no longer provides support for the limit shaft 305. Under the push of the downward pressure spring 302, the connecting slide 307 will slide down along the vertical guide rod 301 The swing pressure plate 303 is pushed by the storage frame 2001 and rotates downward, and the reset torsion spring 306 is deformed accordingly. When the swing pressure plate 303 is out of contact with the storage frame 2001, the swing pressure plate 303 can be swung upward and reset, thereby realizing the function of dewatering the sand and gravel agglomerated in the storage frame 2001.

[0045] like Figure 12-14 As shown, the cleaning mechanism includes a transmission frame 6, a sediment recovery frame 606, a cleaning scraper 6061 and a conveying assembly. The transmission frame 6 is fixedly connected to the outside of the outlet channel 101, and a discharge through hole is opened at the bottom of the transmission frame 6. The sediment recovery frame 606 is fixedly connected to the transmission frame 6. The sediment recovery frame 606 is located in the rotary filter cylinder 203. The sediment recovery frame 606 is fixedly connected to the cleaning scraper 6061. The cleaning scraper 6061 contacts the inner wall of the rotary filter cylinder 203. During the rotation of the rotary filter cylinder 203, the cleaning scraper 6061 scrapes off the sediment on the inner wall of the rotary filter cylinder 203 to clean the rotary filter cylinder 203 to prevent the rotary filter cylinder 203 from being blocked by sediment and affecting the water filtration efficiency. The conveying assembly sends the collected sediment out.

[0046] When the dual-axis motor 201 drives the transmission gear 204 and the rotating filter cylinder 203 to rotate through the driving gear 202, the inner wall of the rotating filter cylinder 203 will contact the cleaning scraper 6061, and the cleaning scraper 6061 will scrape off the sludge stuck to the inside of the rotating filter cylinder 203, and the scraped sludge will fall into the sediment recovery frame 606. The conveying component is driven to rotate by the dual-axis motor 201, and the conveying component will send the sludge in the sediment recovery frame 606 outward, and finally be discharged downward from the bottom outlet of the transmission frame 6.

[0047] like Fig.12 and Fig.13 As shown, the conveying assembly includes a transmission shaft 601, a driving pulley 602, a transmission belt 603, a driven pulley 604 and a spiral conveying rod 607. The transmission frame 6 is rotatably connected with the transmission shaft 601 and the spiral conveying rod 607. The transmission shaft 601 is located at the top of the spiral conveying rod 607. The driving pulley 602 is fixedly connected to the transmission shaft 601. The driven pulley 604 is fixedly connected to the spiral conveying rod 607. The driving pulley 602 and the driven pulley 604 are connected by a transmission belt 603. One end of the spiral conveying rod 607 is located in a sediment recovery frame 606. The spiral conveying rod 607 can send the sediment in the sediment recovery frame 606 outward, and the sediment transported outward by the spiral conveying rod 607 will fall downward from the bottom opening of the transmission frame 6.

[0048] During the operation of the dual-axis motor 201, the driving pulley 602 will be driven to rotate through the transmission shaft 601, and the driving pulley 602 will drive the driven pulley 604 to rotate through the transmission belt 603, and the driven pulley 604 will drive the spiral conveying rod 607 to rotate. During the rotation of the spiral conveying rod 607, the sediment in the sediment recovery frame 606 will be pushed outward, and the sediment in the sediment recovery frame 606 will be discharged downward from the outlet at the bottom of the transmission frame 6 after being sent out.

[0049] like Fig. 9 As shown, it also includes a pushing component for cleaning the debris in the storage frame 2001, and the pushing component includes a fixed top plate 4, a sliding shovel plate 401 and a return spring 402. The fixed top plate 4 is fixedly connected to the L-shaped plate 3, and the sliding shovel plate 401 is slidably connected to the bottom of the fixed top plate 4. After the sliding shovel plate 401 contacts the storage frame 2001, the storage frame 2001 will push the sliding shovel plate 401 to slide along the fixed top plate 4 to push the debris in the storage frame 2001 into the debris recovery frame 102. A return spring 402 is provided between the sliding shovel plate 401 and the fixed top plate 4, and one end of the return spring 402 is fixed to the sliding shovel plate 401, and the other end is fixed to the fixed top plate 4.

[0050] During the rising process of the storage frame 2001, it will contact the sliding shovel plate 401. As the storage frame 2001 continues to rise, under the push of the bottom inclined surface of the storage frame 2001, the sliding shovel plate 401 will slide along the fixed top plate 4 and compress the return spring 402. The sliding shovel plate 401 pushes the debris in the storage frame 2001 into the debris recovery frame 102. When the storage frame 2001 rises to the highest point, the sliding shovel plate 401 just moves to the end of the bottom surface of the storage frame 2001 close to the fixed filter plate 2. Subsequently, during the process of the storage frame 2001 descending and resetting, the return spring 402 will push the sliding shovel plate 401 to slide and reset along the fixed top plate 4.

[0051] like Fig.10 and Fig.11 As shown, it also includes a shielding component for preventing mud and sand from blocking the storage frame 2001. The shielding component includes a mounting frame 5, a sliding shield 501, a connecting tension spring 502, a wedge-shaped fixed block 503, a wedge-shaped rotating block 504, a fixed blocking rod 505 and a connecting torsion spring 506. The mounting frame 5 is fixedly connected to the water inlet 1, and the sliding shield 501 is slidably connected to the mounting frame 5. The sliding shield 501 is connected to the mounting frame 5 through the connecting tension spring 502, and one end of the connecting tension spring 502 is fixed to the mounting frame 5. The other end is fixed to the sliding baffle 501, and a wedge-shaped fixed block 503 is fixed to the sliding baffle 501. A wedge-shaped rotating block 504 is rotatably connected between the wedge-shaped fixed blocks 503. A connecting torsion spring 506 is provided between the wedge-shaped rotating block 504 and the wedge-shaped fixed block 503. One end of the connecting torsion spring 506 is fixed to the wedge-shaped rotating block 504, and the other end is fixed to the wedge-shaped fixed block 503. A fixed stop rod 505 is fixed inside the wedge-shaped fixed block 503, and the fixed stop rod 505 is used to limit the wedge-shaped rotating block 504.

[0052] The bottom surface of the storage frame 2001 is completely fitted with the mounting frame 5. When the storage frame 2001 is pulled up, the storage frame 2001 contacts the wedge-shaped rotating block 504 and pushes it to rotate around the wedge-shaped fixed block 503, connecting the torsion spring 506 to store force and deform. When the wedge-shaped rotating block 504 rotates to a vertical state, the storage frame 2001 rises to the top of the wedge-shaped fixed block 503. At this time, the top inclined surfaces of the wedge-shaped fixed block 503 and the wedge-shaped rotating block 504 just fit with the bottom inclined surface of the storage frame 2001. Under the pull of the connecting tension spring 502, as the storage frame 2001 continues to rise, the connecting tension spring 502 will pull the sliding baffle 501 to slide along the mounting frame 5 and gradually fit with the fixed filter plate 2. At this time, there is a certain gap between the sliding baffle 501 and the mounting frame 5. During the rising process, the sand and gravel in the sewage blocked by the fixed filter plate 2 will remain on the sliding baffle 501, and during the descending process of the storage frame 2001, it will contact the top surfaces of the wedge-shaped fixed block 503 and the wedge-shaped rotating block 504, and under the action of the gravity of the storage frame 2001, the storage frame 2001 will push the sliding baffle 501 to slide along the mounting frame 5 through the wedge-shaped fixed block 503 and the wedge-shaped rotating block 504 and stretch the connecting tension spring 502. When the sliding baffle 501 slides back to its original position, the wedge-shaped rotating block 504 is disengaged from the storage frame 2001. At this time, under the action of the connecting torsion spring 506, the wedge-shaped rotating block 504 rotates to a horizontal state, and the water inlet between the wedge-shaped fixed blocks 503 is opened, so that the sewage and the debris contained therein will flow through between the wedge-shaped fixed blocks 503.

[0053] like Fig.12 , Fig.15 and Fig.16As shown, it also includes a drainage component for pressing water out of the recovered sediment, the drainage component includes a movable push block 605, a sediment collection frame 7, a fixed water filter plate 701, a sliding frame 702, a support spring 703, an L-shaped fixed rod 704, a rotating pressure plate 705 and a filter press torsion spring 706, a movable push block 605 is fixedly connected to the driven pulley 604, and the movable push block 605 is located at the outer edge of the driven pulley 604, a sediment collection frame 7 is provided outside the water outlet channel 101, and a sliding frame 702 is slidably connected to the outside of the sediment collection frame 7, and the sliding frame 7 can be driven to slide downward by the movable push block 605 during the rotation of the driven pulley 604, and a support spring is provided between the sliding frame 702 and the sediment collection frame 7. Spring 703, one end of the support spring 703 is fixed on the sliding frame 702, and the other end is fixed on the sediment collecting frame 7. The support spring 703 can push the sliding frame 702 to slide upward along the sediment collecting frame 7. A fixed water filter plate 701 is fixed in the sediment collecting frame 7, and an L-shaped fixing rod 704 is fixed in the sediment collecting frame 7. A rotating pressure plate 705 is rotatably connected in the sliding frame 702. When the L-shaped fixing rod 704 contacts the rotating pressure plate 705, the rotating pressure plate 705 will be pushed and rotate around the sliding frame 702. A filter press torsion spring 706 is provided between the rotating pressure plate 705 and the sliding frame 702, and one end of the filter press torsion spring 706 is fixed on the rotating pressure plate 705, and the other end is fixed on the sliding frame 702.

[0054] After the spiral conveying rod 607 pushes the silt out of the silt recovery frame 606, the silt will fall downward from the transmission frame 6 to the fixed water filter plate 701 in the silt collection frame 7. When the driven pulley 604 rotates, it will push the sliding frame 702 to slide downward and compress the support spring 703 through the moving push block 605. When the sliding frame 702 descends, it drives the rotating pressure plate 705 to descend. When the rotating pressure plate 705 descends, it will break contact with the L-shaped fixed rod 704. Under the action of the filter press torsion spring 706, the rotating pressure plate 705 turns to a horizontal state. The rotating pressure plate 705 descends with the sliding frame 702 and contacts the silt on the top of the fixed water filter plate 701. The rotating pressure plate 705 will apply pressure to the silt on the top of the fixed water filter plate 701 to remove The water contained in the sediment on the fixed water filter plate 701 is squeezed out, so that the water in the sediment flows downward to the bottom of the fixed water filter plate 701 in the sediment collection frame 7, and finally flows out from the water outlet at the bottom of the sediment collection frame 7. When the movable push block 605 rotates to a high position with the driven pulley 604, the supporting spring 703 will push the sliding frame 702 to rise and reset, and the rotating pressure plate 705 will rise and reset accordingly. In the process of the rotating pressure plate 705 rising, the rotating pressure plate 705 rotates around the sliding frame 702 under the push of the L-shaped fixed rod 704, and the filter press torsion spring 706 will accumulate force and deform, and the adjacent rotating pressure plates 705 will be out of contact, so that the sediment will fall downward from the gap between the rotating pressure plates 705 to the fixed water filter plate 701.
