Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sludge separation device for sewage treatment. Background Art

[0002] In the field of sewage treatment, the separation of sewage and sludge is a key link. Existing sludge separation devices for sewage treatment generally use sedimentation method, which requires a long sedimentation time to achieve the ideal separation effect. The long sedimentation process not only takes up a lot of space, but also prolongs the time of the entire treatment process and reduces the treatment efficiency. Especially in the case of large treatment volume, the extension of sedimentation time will lead to a decrease in the overall operating efficiency of the sewage treatment plant. Secondly, some sludge separation devices for sewage treatment use filter nets for separation. Although the filter net can speed up the separation speed to a certain extent, the filter net is prone to clogging under continuous filtration operations. This is because the suspended matter and solid particles in the sewage gradually accumulate on the filter net, resulting in a smaller aperture or even complete clogging. The clogging of the filter net not only requires frequent cleaning and replacement, which increases maintenance costs, but also directly leads to a decrease in filtration efficiency, and the separation operation cannot be carried out continuously and efficiently. In addition, after separating the sludge, the current separation device cannot realize the operation of filtering and discharging at the same time. This means that the separated sludge needs to be cleaned and transported manually or mechanically on a regular basis, which increases the complexity and labor intensity of the operation. Since filtering and sludge discharge cannot be performed simultaneously, this method greatly reduces the overall separation efficiency, which is particularly prominent during high-load operation.

[0003] Finally, the sludge separated by the existing separation device usually has a high humidity. This is because the water in the sludge cannot be effectively removed during the separation process, resulting in a high moisture content in the separated sludge. The high humidity of the sludge not only increases the processing intensity of the subsequent dehydration process, but also increases the processing volume and processing time.

[0004] Therefore, a sludge separation device for sewage treatment is proposed to solve the above problems. Summary of the invention

[0022] The beneficial effects of the present invention are as follows: the present invention continuously pours sewage into the interior of the filter box by arranging filter cartridge three, fixed pipe one and threaded blade two, at which the sewage entering the filter box will be preliminarily filtered by filter cartridge three, leaving a large amount of sludge at the bottom of the inner cavity of the filter box, at which the sewage after preliminarily filtration will enter filter cartridge three and pass into the fixed box through fixed pipe one, and due to the operation of the driving motor, one transmission wheel can be rotated, and the other transmission wheel can be driven to rotate through the transmission belt, and due to the rotation of the two transmission wheels, the filter cartridge three can be driven to rotate, thereby achieving the effect of replacing the filter surface, and at the same time, due to the rotation of the filter cartridge three, the scraper block two can scrape the filter cartridge three and replace the filter surface. Scraping off the sludge attached to the surface of cartridge three can avoid clogging of filter cartridge three and ensure the filtering effect of filter cartridge three. Due to the operation of the electric telescopic rod, the sealing block can rise and release the seal on the port of filter cartridge four. Due to the operation of power motor two, shaft two can drive threaded leaf two to rotate, and transport the sludge inside the filter box to the inside of filter cartridge four, initially drain through filter cartridge four, and as threaded leaf two continues to rotate, it is transported to the inside of fixed tube two. This design can realize filtering and discharging sludge at the same time, avoiding the need for regular manual or mechanical cleaning and transportation of separated sludge, reducing the complexity and labor intensity of operation, and thus improving the overall separation efficiency.

[0023] The present invention arranges a gentle slope guide plate, a steep slope guide plate and an impeller. Once the sewage flows into the fixed box through the fixed pipe, it will first fall on the gentle slope guide plate and spread out in a fan shape on the gentle slope guide plate. The gentle slope of the gentle slope guide plate will buffer the flow velocity of the sewage and drive the impeller to rotate. The flocculant that falls between the blades of the middle impeller in the storage box will be added to the downstream sewage through the rotation of the impeller. When the sewage flows to the contact slope, it will be affected by the steep slope of the contact slope to increase the flow velocity. When the sewage flows out of the steep slope guide plate, it will impact the surface of the contact slope due to its relatively large initial velocity. During the impact, the flocculant carried in the sewage will be fully mixed with the sewage in this section. As it flows to the lower part of the fixed box, the flocculant will accumulate smaller particles in the sewage during the mixing process. The sludge impurities increase their mass, and then accelerate their sinking and separation in the water body under the action of gravity. As the sewage water level inside the fixed box increases, when the water level rises to the top of the U-shaped tube, the water inside the fixed box will pass through the filter cartridge 2 and be discharged into the clean water tank inside the diversion box through the U-shaped tube. Since the port diameter of the U-shaped tube inside the fixed box is larger, the drainage efficiency of the U-shaped tube is greater than the drainage speed of the fixed tube one, so that the water level inside the fixed box can drop rapidly until the water level is lower than the port of the U-shaped tube and then the drainage stops. As the fixed tube one continues to drain, the water level inside the fixed box will rise again, forming a reciprocating process to achieve intermittent drainage of the U-shaped tube. During the intermittent process, the water level inside the fixed box rises, which can provide sufficient time for the sedimentation and separation of sludge impurities.

[0024] The present invention is provided with a connecting pipe, a movable bent rod and a piston rod three. During the operation of the power motor two, the power motor one will run at the same time. Due to the operation of the power motor one, the sludge can be transported to the interior of the filter cartridge one. At the same time, the sludge inside the fixed pipe two will also enter the interior of the filter cartridge one under the transporting action of the threaded leaves two. With the rotation of the threaded leaves one, the sludge can be transported to abut against the abutment block and the pressure block to block the sludge. As the threaded leaves one continue to rotate, the sludge will be compressed inside the filter cartridge one, thereby squeezing out the water contained in the sludge and achieving the effect of sludge dehydration. In the process of sludge dehydration, as the sludge squeezes the pressure block, the pressure block can be moved to the right side by the extrusion force, and the piston rod one can be pushed to move and compress the spring one. Since the inner diameter of the connecting pipe is small, the exhaust of the fixed cartridge is The efficiency is low, and at the same time, it can have a greater damping effect on the movement of the pressure block, so that the movement of the pressure block and the piston rod 1 is slow, and the spring 1 slowly transports the gas to the inside of the installation cylinder, pushing the piston rod 2 to rise slowly. When the piston rod 2 rises and abuts against the moving bent rod, driving the moving bent rod to rise at the same time, the moving bent rod can drive the sealing sleeve to rise and release the seal of the air hole. At this time, the spring 3 is compressed, so it can be determined that the sludge dehydration at the inner end of the filter cartridge 1 is completed. At this time, the spring 2, which is in a compressed state, will drive the piston rod 3 to rise under the action of elastic recovery. Due to the rise of the piston rod 3, the resistance block can be driven to rise, and the resistance block and the pressure block can be released to block the sludge. Under the transportation of the threaded blade 1, the dehydrated sludge is discharged to the sludge tank inside the diversion box. This design can realize active discharge after the sludge is dehydrated. BRIEF DESCRIPTION OF THE DRAWINGS

Both sides of the inside of the fixed block 302 are fixedly connected with scraper blocks 303. Two transmission wheels 304 are movably installed on the top of the filter box 301. A filter cartridge 305 that can be coaxially connected to the transmission wheel 304 is movably installed inside the fixed block 302. A driving motor 306 is installed on the top of the filter box 301. The output end of the driving motor 306 is connected to a transmission wheel 304. The outside of the filter cartridge 305 can abut against the scraper block 303. The driving wheels 304 are connected by a transmission belt 308, a fixed pipe 1 307 is movably sleeved at the lower part of the interior of the filter cartridge 305, the bottom end of the fixed pipe 1 307 passes through the filter cartridge 305 and the filter box 301 and extends to the interior of the fixed box 201, the fixed pipe 1 307 is fixedly connected to the filter box 301, a power motor 2 311 is installed on one side of the filter box 301, and a filter cartridge 4 314 is fixedly connected to the other side of the filter box 301, the power motor 2 311 is driven and connected to the rotating shaft 2 312, and the other end of the rotating shaft 2 312 passes through the filter box 301 and extends to the filter cartridge 4 3 14, the outside of the filter cartridge four 314 is fixedly sleeved with a threaded leaf two 313, transparent covers 318 are installed on the front and rear sides of the filter box 301, and an infrared sensor 309 and an infrared receiver 310 facing the transparent cover 318 are installed on the front and rear sides of the filter box 301 respectively, the other end of the filter cartridge four 314 is connected to a fixed pipe two 315 located outside the fixed box 201, and an electric telescopic rod 316 is installed on the top of the fixed box 201, and the output end of the electric telescopic rod 316 is connected to a sealing block 317 located inside the fixed pipe two 315 and capable of sealing the other end of the filter cartridge four 314.

[0041] The above scheme is adopted: sewage is continuously poured into the interior of the filter box 301. At this time, the sewage entering the filter box 301 will be preliminarily filtered by the filter cartridge three 305, leaving a large amount of sludge at the bottom of the inner cavity of the filter box 301.

[0042] Example 2, reference Figures 1 to 610 is a second embodiment of the present invention, which is based on the previous embodiment. A power motor 1 209 on the same side as the power motor 2 311 is installed on the fixed box 201, and a filter cartridge 1 212 on the same side as the fixed pipe 2 315 is connected to the fixed box 201.

The outer fixed sleeve of the rotating shaft 1 210 is connected with a threaded leaf. A fixed box 201 is provided with a gentle slope guide plate 202 located below a fixed pipe 307, one side of the gentle slope guide plate 202 is connected to a steep slope guide plate 203, a contact slope 204 close to the steep slope guide plate 203 is provided inside the fixed box 201, a storage box 205 located above the gentle slope guide plate 202 is fixedly provided inside the fixed box 201, an impeller 206 is movably provided inside the storage box 205, and one side of the storage box 205 is connected to a A feed pipe 207 can be extended to the outside of the fixed box 201, and the other end of the feed pipe 207 is fixedly connected to a funnel 208. A support frame 213 located below the gentle slope guide plate 202 is installed inside the fixed box 201. The front and rear sides of the bottom of the support frame 213 are connected to a fixed block 214. Both sides of the inside of the fixed block 214 are connected to a scraper block 217. A filter cartridge 216 that can abut against the scraper block 217 is movably installed inside the fixed block 214. The fixed box 201 is provided with a filter cartridge 216 that can abut against the scraper block 217. 1 is fixedly installed with a U-shaped tube 218, one end of the U-shaped tube 218 extends to the inside of the filter cartridge 216 and the port is in a positive cone shape, the U-shaped tube 218 is movably sleeved with the inside of the filter cartridge 216, and the other end of the U-shaped tube 218 extends to the clean water tank inside the diversion box 100, and the inside of the filter cartridge 3 305 is fixedly connected with a connecting rod 215, and the bottom end of the connecting rod 215 passes through the fixed tube 1 307, the gentle slope guide plate 202 and the U-shaped tube 218 and is connected to the filter cartridge 2 216.

[0043] The above scheme is adopted: when in use, the operator can add the flocculant into the storage box 205 through the feed pipe 207 through the funnel 208, and at the same time, part of the flocculant in the storage box 205 will fall between the blades of the impeller 206 below the storage box 205, and the sewage flowing into the fixed box 201 through the fixed pipe 307 will first fall on the gentle slope guide plate 202, and spread out in a fan shape on the gentle slope guide plate 202, and be buffered by the gentle slope of the gentle slope guide plate 202, reducing part of the flow rate, and in the action of sewage flowing down The impeller 206 is driven to rotate, and through the rotation of the impeller 206, the flocculant falling into the storage box 205 between the blades of the middle impeller 206 is added to the downstream sewage. When the sewage flows to the contact slope 204, it will be affected by the steep slope of the contact slope 204 to increase the flow rate. When it flows out of the steep slope guide plate 203, it will impact the surface of the contact slope 204 due to its relatively large initial velocity. During the impact, the flocculant carried by the sewage will be fully mixed with the sewage in this section, and as it flows into the fixed box 201, during the mixing process, the flocculant will accumulate smaller sludge impurities in the sewage, increase its mass, and then accelerate its sinking and separation in the water body under the action of gravity. As the sewage water level inside the fixed box 201 increases, when the water level rises to the top of the U-shaped tube 218, the water inside the fixed box 201 will pass through the filter cartridge 216 and be discharged into the clean water tank inside the diversion box 100 through the U-shaped tube 218. Since the port diameter of the U-shaped tube 218 inside the fixed box 201 is The drainage efficiency of the U-shaped tube 218 is larger than the drainage speed of the fixed tube 307, so that the water level inside the fixed box 201 can drop rapidly until the water level is lower than the port of the U-shaped tube 218 and the drainage is stopped. As the fixed tube 307 continues to drain, the water level inside the fixed box 201 will rise again, forming a reciprocating process to achieve intermittent drainage of the U-shaped tube 218. During the intermittent process, the water level inside the fixed box 201 rises, which can provide sufficient time for the sedimentation and separation of sludge impurities.

[0044] Due to the rotation of filter cartridge three 305, the connecting rod 215 can drive filter cartridge two 216 to rotate. During the rotation of filter cartridge two 216, the scraper block one 217 will scrape off the sludge attached to the surface of filter cartridge two 216, thereby ensuring the filtering performance of filter cartridge two 216 and the separation efficiency of filter cartridge two 216 for sewage. At the same time, the combination of sedimentation separation and separation of filter cartridge two 216 can reduce the filtering intensity of filter cartridge two 216 and further improve the efficiency of sewage filtration and sludge separation.

The other side of the piston rod 1 405 is connected to a spring 1 406, and the other end of the spring 1 406 is connected to the fixed cylinder 404. A mounting cylinder 408 is installed inside the stop block 402, and the mounting cylinder 408 is connected to the fixed cylinder 404 through a connecting pipe 407. The inner diameter of the connecting pipe 407 is one tenth of the inner diameter of the fixed cylinder 404. A mounting frame 412 is connected to the top of the shunt box 100, and a driving cylinder 413 is fixedly installed inside the mounting frame 412. A piston rod 3 414 is sleeved inside the driving cylinder 413, and an air cavity is opened inside the piston rod 3 414. A plurality of air holes 417 are opened around the bottom end of the piston rod 3 414. A card slot located inside the driving cylinder 413 is opened on both sides of the , a spring 2 415 is sleeved on the outside of the piston rod 3 414, one end of the spring 2 415 is connected to the piston rod 3 414, and the other end of the spring 2 415 is connected to the driving cylinder 413, an air pump 421 is fixedly installed on the top of the driving cylinder 413, the air pump 421 is communicated with the driving cylinder 413, an air core assembly 420 is installed on the outside of the driving cylinder 413, and an air leakage monitoring element is provided on the air core assembly 420, both sides of the interior of the mounting frame 412 are movably sleeved with card blocks 422, one side of the card block 422 is connected to a spring 423, and the other end of the spring 423 is connected to the mounting frame 412, A pressure sensor capable of monitoring the rebound pressure of spring four 423 is arranged inside the mounting frame 412, a piston rod two 409 is sleeved inside the mounting cylinder 408, a fixing frame 410 is installed above the inside of the mounting cylinder 408, a movable bent rod 411 is movably sleeved inside the fixing frame 410, one end of the movable bent rod 411 is connected to a sealing sleeve 418 sleeved on the outside of the piston rod three 414, and the sealing sleeve 418 can close the air hole 417, the outside of the piston rod three 414 is fixedly sleeved with a fixing ring 416 located above the sealing sleeve 418, and a spring three 419 located on the outside of the piston rod three 414 is connected between the fixing ring 416 and the sealing sleeve 418.

[0046] The above scheme is adopted: during the operation of the power motor 211, the power motor 1 209 will run at the same time. Due to the operation of the power motor 1 209, the sludge can be transported to the interior of the filter cartridge 1 212. At the same time, the sludge inside the fixed tube 2 315 will also enter the interior of the filter cartridge 1 212 under the transporting action of the threaded blade 2 313. With the rotation of the threaded blade 1 211, the sludge can be transported to the abutment block 402 and the pressure block 403 to block the sludge. As the threaded blade 1 211 continues to rotate, the sludge will be compressed inside the filter cartridge 1 212, thereby squeezing out the water contained in the sludge to achieve the effect of sludge dehydration. In the process of sludge dehydration, as the sludge squeezes the pressure block 403, the pressure block 403 can be moved to the right by the extrusion force, and the piston rod 1 405 is pushed to move and compress the spring 1 406. Since the inner diameter of the connecting tube 407 is small, the exhaust efficiency of the fixed cylinder 404 is relatively high. The spring 406 slowly delivers the gas to the inside of the mounting tube 408, pushing the piston rod 409 to rise slowly. When the piston rod 409 rises and contacts with the moving bent rod 411, driving the moving bent rod 411 to rise at the same time, the moving bent rod 411 can drive the sealing sleeve 418 to rise and release the seal of the air hole 417. At this time, the spring 419 is compressed, so that it can be determined that the sludge dehydration at the inner end of the filter cartridge 212 is completed. At this time, the spring 415 in the compressed state will drive the piston rod 414 to rise under the action of elastic recovery. Due to the rise of the piston rod 414, the block 402 can be driven to rise, and the block 402 and the pressure block 403 can be released to block the sludge. Under the transportation of the threaded leaf 211, the dehydrated sludge is discharged to the sludge tank inside the diverter box 100.

[0047] As the piston rod 3 414 rises, the gas inside the driving cylinder 413 can be discharged through the air cavity of the piston rod 3 414 and the sealing sleeve 418, and finally the piston rod 3 414 is pushed to the block 422 until the block 422 is engaged in the slot inside the piston rod 3 414. During the engagement process of the block 422, the block 422 will move outward and cause the spring 423 to be compressed and reset once, and at the same time trigger the pressure sensor, and the control end drives the air pump 421 to operate. When the third filter element 414 is engaged with the clamping block 422, the abutting block 402 will be completely separated from the front of the filter cartridge 1 212. At the same time, the pressure block 403 is no longer subjected to pressure. Under the elastic force recovery action of the spring 1 406, the piston rod 1 405 and the pressure block 403 are pushed up and reset. Then, the piston rod 2 409 is sucked down through the connecting pipe 407 and separated from the movable bent rod 411. Under the elastic force recovery action of the spring 3 419, the sealing sleeve 418 is pushed to reset and the air hole 417 is sealed. When the air pressure in the air pump 421 is greater than the spring four 423, the piston rod three 414 will move downward and release the engagement with the block 422, disengaging from the block 422 and compressing the spring two 415. As the piston rod three 414 descends, The abutment block 402 and the pressure block 403 can be lowered to the filter cartridge 212 again to continue to abut against the sludge. At this time, the piston rod 414 will drop to the lowest point. As the air pump 421 continues to pressurize, the limit of the air core assembly 420 will be reached, and the leakage of the air core assembly 420 will be detected by the leakage monitoring element, and the air pump 421 will be turned off through the control end. This design can realize active discharge after sludge dehydration, and realize active closure after active discharge to facilitate subsequent sludge dehydration operations.
