Description

Technical Field

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

[0002] With the acceleration of urbanization and the development of industry, the amount of sewage discharge is increasing. In order to protect the environment and water resources, it is necessary to effectively treat sewage to remove pollutants and sludge. Through appropriate treatment methods, the water content of sludge can be reduced, and the volume of sludge can be reduced to facilitate subsequent treatment and disposal. Traditional sewage treatment methods, such as sedimentation and filtration, may have problems such as low efficiency, poor effect, and large footprint when treating sludge. In order to meet the treatment of sewage, the research and development and application of sewage sludge separation equipment, by separating solid sludge from liquid in sewage, reduces the content of suspended matter and pollutants in sewage, improves water quality, thereby meeting environmental protection requirements and achieving standard sewage discharge.

[0003] There are still many inconveniences in the use of current equipment; The specific defects are as follows: Firstly, due to the high viscosity of the sludge and the problem of uneven pressure distribution during the filter pressing process, the sludge will adhere to the filter cloth or filter plate of the filter pressing equipment, resulting in sludge residue. The existing cleaning method usually uses manual pushing of the filter plate to push down the sludge between the filter plates. The speed of manual cleaning is usually slow, and it is difficult to complete the cleaning of a large amount of sludge in a short time, thus affecting the progress of the entire sewage treatment process. In addition, the quality of manual cleaning is easily affected by the personal skills and work attitude of the workers, resulting in incomplete cleaning, and the sludge remains on the filter pressing equipment. The residual sludge will clog the filter holes and affect the subsequent filtration effect.

[0004] Secondly, when collecting the sludge after filtration, due to the uneven mixing of sewage and sludge before filtration and the uneven pressure distribution during filtration, there is a high moisture content in the sludge after filtration. The high water content of the sludge will increase the difficulty in subsequent processing and disposal. For example, during transportation, sludge with high water content will increase transportation costs and may leak during transportation, causing environmental pollution. Secondly, using sludge with too high water content for land improvement or landfill will reduce soil permeability and affect soil ventilation and drainage performance, thereby adversely affecting land use.

Vibration can loosen the contact surface between the sludge and the filter press equipment, making it easier to shake the sludge out of the equipment. Compared with traditional manual cleaning methods, vibration cleaning can greatly improve cleaning efficiency, save time and labor costs, and vibration can make the sludge fall off from the filter press equipment more evenly, reduce the amount of residual sludge, improve the integrity of sludge discharge, and facilitate subsequent treatment and disposal.

[0017] 2. Through the coordinated use of the mixing box and the detection mechanism, the water content inside the sludge can be judged by observing the degree of descent of the weighing box and comparing it with the normal sludge weight, and then the sewage can be adjusted, which solves the problem of whether the sludge after filtration is not easy to observe. Through an easy-to-observe method, the sludge treatment results of each batch can be monitored to ensure the consistency and stability of the treatment effect, avoid the situation where the treatment does not meet the standards, and intuitively understand the treatment effect of the sludge. When the sludge is found to be unqualified, the filtration parameters, flocculant dosage and other treatment processes can be adjusted in time to improve the quality of sludge treatment.

[0018] 3. Through the coordinated use of the testing agency and the classification agency, the qualified sludge and the unqualified sludge are classified and collected by the classification agency, which solves the problem of high moisture content in the sludge affecting subsequent treatment. The qualified sludge and the unqualified sludge are collected separately, and more appropriate treatment methods can be adopted for sludge of different properties. Qualified sludge can be directly disposed of or utilized in the future, while unqualified sludge can be further treated or the process can be adjusted to improve its quality to meet the qualified standards. This can avoid unified treatment of all sludge and improve the overall treatment efficiency. In addition, classified collection helps to better monitor the quality of the sludge treatment process. Through the analysis of unqualified sludge, problems in the treatment process can be found, and process parameters can be adjusted in time to improve the quality stability of sludge treatment.

[0019] 4. Through the coordinated use of the vibration mechanism and the detection mechanism, the sludge after filtration can be more thoroughly shaken out of the filter press equipment through the detection mechanism to avoid sludge residue, and then the weight of the sludge can be detected, so that the detection mechanism can more accurately reflect the actual sludge output, which is helpful to accurately monitor and manage the internal water content of the sludge in the sewage treatment process.

Figure 5 , Figure 6 and Figure 7 In the embodiment, the outer frame 1 is internally slidably connected with a driving spindle 314 and an adjusting spindle 316, and the driving spindle 314 is internally slidably connected with a power sliding shaft 319. Figure 7In the embodiment, a fixed block 3111 is fixedly connected to the surface of the power sliding shaft 319, a No. 3 spring 3112 is fixedly connected to the surface of the fixed block 3111, the No. 3 spring 3112 is fixedly connected to the driving main shaft 314, a No. 1 spring 315 is fixedly connected to the side wall of the outer frame 1, the No. 1 spring 315 is fixedly connected to one end of the driving main shaft 314, the filter press plate 311 slides in the direction of the No. 1 spring 315 under the pull of the electric telescopic rod, when the rightmost filter press plate 311 The first spring 315 is compressed under the push of the push main shaft 314. Since the third spring 3112 is fixedly connected between the push main shaft 314 and the blocking block 3111 on the surface of the power slide shaft 319, the push main shaft 314 slides, and the power slide shaft 319 has a limiting effect on the blocking block 3111 through the blocking support shaft 318, so that the push main shaft 314 can slide. The third spring 3112 is compressed and stored under the push of the main shaft 314, and the inner sliding connection of the outer frame 1 is provided with a positioning support shaft 318, and the inner fixed connection of the outer frame 1 is provided with a second spring 317, and the second spring 317 is fixedly connected to the positioning support shaft 318, and an adjustment slot is provided on the surface of the positioning support shaft 318, and the adjustment main shaft 316 is slidably connected to the inside of the adjustment slot on the surface of the positioning support shaft 318. As the filter press plate 311 continues to slide, the filter press plate 311 and the The adjustment spindle 316 contacts the power sliding shaft 319, thereby pushing the adjustment spindle 316 to slide in the direction of the power sliding shaft 319. Since one end of the adjustment spindle 316 is provided with an inclined surface and the interior of the positioning support shaft 318 is provided with an adjustment slot, the inclined surface of the adjustment spindle 316 fits with the adjustment slot on the surface of the positioning support shaft 318, and the adjustment spindle 316 slides, thereby pushing the positioning support shaft 318 to slide upward through the inclined surface, thereby pushing the positioning support shaft 318 to leave the sliding path of the positioning fixed block 3111, as shown in FIG. Figure 8 In the embodiment, the outer wall surface of the outer frame 1 is fixedly connected with a fixed side plate 3114, the surface of the fixed side plate 3114 is rotatably connected with a synchronous shaft 3115, the surface of the synchronous shaft 3115 is fixedly connected with a synchronous gear 3113 and a rotating rotating plate 3110, the surface of the power sliding shaft 319 is provided with a tooth groove, the tooth block on the surface of the synchronous gear 3113 is meshed with the tooth groove on the surface of the power sliding shaft 319, one end of the rising push rod 313 is rotatably connected to the surface of the rotating rotating plate 3110, the surface of the outer frame 1 is fixedly connected with a fixed clamping shaft, and one end of the rising push rod 313 is rotatably connected to the surface of the fixed clamping shaft on the outer frame 1, as shown in FIG. Figure 4 and Figure 5The support shaft 312 is fixedly connected with a bearing support shaft 3116 on the surface of the supporting slide shaft 312, and the bearing support shaft 3116 is L-shaped. The bearing support shaft 3116 is located above the lifting push rod 313, and the bearing support shaft 3116 is located inside the sliding path of the lifting push rod 313. The power slide shaft 319 loses the restriction of the positioning support shaft 318 on the positioning solid block 3111. The power slide shaft 319 slides toward the direction of the rotating plate 3110 under the push of the third spring 3112. Since the tooth groove on the surface of the power slide shaft 319 is engaged with the synchronous gear 3113, the power slide shaft 319 slides, thereby pushing the synchronous gear 3113 to rotate and then driving the positioning solid block 3111 to rotate synchronously through the synchronous shaft 3115. Since one end of the lifting push rod 313 is rotatably connected to the fixed clamping shaft on the surface of the outer frame 1, one end of the lifting push rod 313 is rotatably connected to the surface of the rotating rotating plate 3110, the rotating rotating plate 3110 rotates, thereby driving the upper When the jack 3110 is in the unlocking state, the lifting push rod 313 slides downward, and the abutment support shaft 3116 loses the support of the lifting push rod 313 and slides downward, and collides with the cross bar on the surface of the outer frame 1, thereby generating vibration, and then vibrates the sludge attached to the filter cloth on the surface of the filter plate 311. The locking block 3111 is provided with an inclined surface on the side close to the third spring 3112, and the locking support shaft 318 is provided with an inclined surface on the side away from the third spring 3112.

[0026] In a further embodiment, a cross bar is arranged on the surface of the outer frame 1 , the cross bar on the surface of the outer frame 1 is located below the supporting sliding shaft 312 , and a sliding pull rod is arranged between adjacent filter press plates 311 .

[0027] The effects achieved by this embodiment are as follows: the cross bar on the surface of the outer frame 1 is located below the supporting slide shaft 312. When the supporting slide shaft 312 loses the support of the rising push rod 313 and slides downward, the filter press plate 311 on the surface of the supporting slide shaft 312 collides with the cross bar on the surface of the outer frame 1 and generates vibration. The sliding pull rod between adjacent filter press plates 311 ensures that the multiple filter press plates 311 are opened at equal intervals when the electric telescopic rod is pulled open, thereby ensuring the discharge space for the sludge inside the filter press plates 311.

[0028] like Figure 2 , Figure 3 , Fig. 9 , Fig.10 and Fig.11 As shown, Figure 2 and Figure 3In the embodiment, the detection mechanism 4 includes a material discharge box 411, which is fixedly connected to the inside of the outer frame 1, a weighing box 412 is slidably connected to the inside of the material discharge box 411, a bottom sealing plate 413 is slidably connected to the bottom surface of the weighing box 412, a fixed pull frame 414 is fixedly connected to the inside of the material discharge box 411, the bottom sealing plate 413 is slidably connected to the inside of the fixed pull frame 414, and an electric telescopic rod is arranged inside the material discharge box 411, and the electric telescopic rod is fixedly connected to the surface of the fixed pull frame 414, as shown in FIG. Fig. 9 and Fig.10 In the embodiment, a sliding pressure plate 415 is fixedly connected to the surface of a weighing box 412, and a pressure spring 417 is fixedly connected to the interior of a discharge box 411, and the pressure spring 417 is fixedly connected to the lower surface of the sliding pressure plate 415. The sludge after filtration falls from the filter press plate 311 and enters the interior of the weighing box 412 through the inclined surface of the discharge box 411. The weighing box 412 pushes the weighing box 412 to slide downward under the action of the sludge's own gravity, and the pressure spring 417 is compressed under the push of the sliding pressure plate 415 on the surface of the weighing box 412.

Fig.10In the embodiment, a restoring spring 418 is fixedly connected to the interior of the discharge box 411, and a sliding baffle is fixedly connected to the upper surface of the inclined push plate 416. The restoring spring 418 is fixedly connected to the sliding baffle on the upper surface of the inclined push plate 416. One end of the inclined push plate 416 is provided with an inclined surface, and the inclined surface of the inclined push plate 416 is located inside the sliding path of the sliding pressure plate 415. When the moisture in the sludge is too high, the pressure spring 417 continuously compresses the sliding pressure plate 415 to contact the inclined push plate 416. Since one end of the inclined push plate 416 is provided with an inclined surface and is located inside the sliding path of the sliding pressure plate 415, the sliding pressure plate 415 slides downward through the contact with the inclined surface of the inclined push plate 416, thereby pushing the inclined push plate 416 to move away Slide in the direction away from the weighing box 412. Since the inclined push plate 416 is fixedly connected to the discharge frame 419, the discharge frame 419 filled with chemical substances is pushed to slide in the direction close to the mixing box 2. A feeding trough is provided on the upper surface of the mixing box 2. The lower surface of the discharge sealing plate 4110 is located at the same horizontal plane as the upper surface of the mixing box 2. When the discharge frame 419 is located at the feeding trough on the upper surface of the mixing box 2, the discharge sealing plate 4110 rotates around the side solid block 4111 on the surface of the discharge frame 419, thereby the chemical substances inside the discharge frame 419 are fed into the inside of the mixing box 2 through the feeding trough on the surface of the mixing box 2, so that the tiny particles and colloidal substances in the sewage are condensed into larger flocs, which are easier to precipitate or filter.

[0029] like Figure 2 , Figure 3 and Fig.12 As shown, Figure 2 and Figure 3 In the embodiment, the classification mechanism 5 includes a fixed bottom plate 511, which is fixedly connected to the inside of the outer frame 1. The upper surface of the fixed bottom plate 511 is fixedly connected to four No. 1 supports 515 and two No. 2 supports 519.

The classification box 513 is rotatably connected to one end of the No. 1 support rod 517. The surface of the classification box 513 is fixedly connected with four rotating shafts 516, and the rotating shafts 516 are all slidably connected to the inside of the clamping shaft groove on the surface of the No. 1 support 515. A connecting support rod 5111 is fixedly connected between adjacent limit pressure rods 514, and a driving shaft is fixedly connected between the two connecting support rods 5111. When the sludge moisture content is qualified, the rotating shaft 516 is rotatably connected to the No. 1 support. The shaft slot on the surface of 515, the left limiting pressure rod 514 is located at the top of the left rotating shaft 516 under the elastic force of the No. 4 spring 5110, thereby giving a limit to the rotating shaft 516, and one end of the No. 2 support rod 518 is fixedly connected to the motor output shaft. The No. 2 support rod 518 drives the No. 2 support rod 518 to rotate clockwise under the drive of the motor output shaft, thereby giving an upward force to the classification box 513 through the No. 1 support rod 517. Since the right rotating shaft 516 is in an open state and the left rotating shaft 516 is in a closed state, the No. 1 support rod 517 gives an upward force to the classification box 513, thereby pushing the classification box 513 to rotate counterclockwise around the rotating shaft 516, so that the qualified sludge is poured into the left collection box 5112 for centralized collection, and the discharge box 411 The inside of the box is slidably connected with an adjusting side plate 512, and the adjusting side plate 512 is slidably connected to the bottom of the bottom sealing plate 413. The limiting pressure rod 514 is in the same vertical plane as the adjusting side plate 512. The surface of the No. 1 support 515 on the right side is fixedly connected with a No. 4 spring 5110, and the No. 4 spring 5110 and the right limiting pressure rod 514 are fixedly connected. Two collecting boxes 5112 are fixedly connected to the upper surface of the fixed bottom plate 511. The two collecting boxes 5112 are symmetrically arranged on both sides of the classification box 513. The length of the No. 1 support rod 517 is equal to that of the No. 2 support rod 518, and the length of the No. 1 support rod 517 and the No. 2 support rod 518 is greater than half the length of the side length of the classification box 513. When the sludge moisture content is unqualified, the weighing box 412 is pushed by the sludge's own gravity. The bottom cover 413 drives the adjusting side plate 512 to slide downward. As the sliding degree increases, the adjusting side plate 512 is driven to slide downward through the bottom cover 413. Since one end of the adjusting side plate 512 is set as an inclined surface, and the inclined surface of the adjusting side plate 512 contacts the limiting pressure rod 514, the adjusting side plate 512 slides downward, thereby pushing the right limiting pressure rod 514 to slide through the inclined surface, thereby limiting the right rotation axis 516 through the right limiting pressure rod 514, and the left limiting pressure rod 514 slides away from the classification box 513 under the action of the pushing shaft on the surface of the connecting support rod 5111, thereby releasing the limit of the left rotation axis 516 by the left limiting pressure rod 514, and driving the No. 1 support rod 517 to rotate through the No. 2 support rod 518, thereby pushing the classification box 513 to rotate around the right rotation axis 516.Thus, the unqualified sludge in the classification box 513 is pushed into the right collection box 5112.

[0030] Further embodiment: a limiting block is provided on the surface of the left limiting pressure rod 514. When the left limiting pressure rod 514 slides after being pushed by the adjusting side plate 512, when the right limiting pressure rod 514 completely limits the right rotating surface axis 516, the position of the limiting pressure rod 514 is fixed by the limiting block.

[0031] The effects achieved by this embodiment are as follows: preventing the classification box 513 from returning to the state of feeding into the collection box 5112 on the left side where qualified sludge is stored under the elastic force of the No. 4 spring 5110.

[0032] The following is the entire working process and working principle of the above embodiment: Initially: the rising push rod 313 is located below the horizontal bar on the surface of the outer frame 1, the multiple filter plates 311 are in a retracted state, one end of the locking support shaft 318 is located inside the sliding path of the locking solid block 3111 and the locking support shaft 318 is located on the right side of the locking solid block 3111, the No. 1 spring 315 and the locking support shaft 318 are both in an uncompressed state, the bottom sealing plate 413 is located at the bottom of the weighing box 412 and seals the bottom of the weighing box 412, the unloading frame 419 is aligned with the discharge port of the internal storage trough of the unloading box 411, the left rotating surface shaft 516 is in a limited state, and the right rotating surface shaft 516 is in an active state.

[0033] During operation: the pollutants inside the mixing box 2 enter the filter press plate 311 through the conduit, and pressure is applied to the filter press plate 311 through the air pressure device. Under the pressure given by the air pressure device, the moisture inside the pollutants passes through the filter cloth inside the filter press plate 311 and enters the liquid collecting tank from the water outlet on the surface of the filter press plate 311, while the pollutants will stay on the surface of the filter cloth inside the filter press plate 311 to form sludge blocks. When the pollutants inside the filter press plate 311 are filtered, the filter press plate 311 slides in the direction of the No. 1 spring 315 under the pull of the electric telescopic rod. When the rightmost filter press plate 311 contacts the pushing spindle 314, the pushing spindle 314 slides on the surface of the power slide shaft 319 under the push of the filter press plate 311, and the No. 1 spring 315 is compressed under the push of the pushing spindle 314. The third spring 3112 is fixedly connected between the surface blocking block 3111 to push the main shaft 314 to slide, and the power sliding shaft 319 has a limiting effect on the blocking block 3111 through the blocking support shaft 318, so that the third spring 3112 is compressed and stored under the push of the pushing main shaft 314. As the filter press plate 311 continues to slide, the filter press plate 311 contacts the adjustment main shaft 316, thereby pushing the adjustment main shaft 316 to slide in the direction of the power sliding shaft 319. Since an inclined surface is provided at one end of the adjustment main shaft 316 and an adjustment slot is provided inside the blocking support shaft 318, the inclined surface of the adjustment main shaft 316 fits with the adjustment slot on the surface of the blocking support shaft 318, and the adjustment main shaft 316 slides, thereby pushing the blocking support shaft 318 to slide upward through the inclined surface, thereby pushing the blocking support shaft 318 to leave the sliding path of the blocking block 3111. At the same time, the power sliding shaft 319 loses the restriction of the locking support shaft 318 on the locking fixed block 3111, and the power sliding shaft 319 slides toward the rotating rotating plate 3110 under the push of the No. 3 spring 3112. Since the tooth groove on the surface of the power sliding shaft 319 meshes with the synchronous gear 3113, the power sliding shaft 319 slides, thereby pushing the synchronous gear 3113 to rotate and then driving the locking fixed block 3111 to rotate synchronously through the synchronous shaft 3115. Since one end of the lifting push rod 313 is rotatably connected to the fixed locking shaft on the surface of the outer frame 1, one end of the lifting push rod 313 is rotatably connected to the surface of the rotating rotating plate 3110, the rotating rotating plate 3110 rotates, thereby driving the lifting push rod 313 to rotate around the fixed locking shaft on the surface of the outer frame 1. Since the support sliding shaft 312 surface abutting support shaft 3116 is located inside the rotation path of the lifting push rod 313, the lifting push rod 313 rotates to drive the supporting sliding shaft through the abutting support shaft 3116 312 slides upward, thereby pushing the filter plate 311 on the surface of the supporting slide shaft 312 to slide upward. When the rotation degree of the rotating plate 3110 increases, the rising push rod 313 slides downward, and the abutment support shaft 3116 loses the support of the rising push rod 313 and slides downward, and the filter plate 311 collides with the cross bar on the surface of the outer frame 1, thereby generating vibration, and then the sludge attached to the filter cloth on the surface of the filter plate 311 is vibrated off, solving the problem that the filter cloth or filter plate of the filter press equipment is attached with sludge, thereby affecting the filter press effect. The vibration can loosen the contact surface between the sludge and the filter press equipment, thereby making it easier to shake the sludge out of the equipment. Compared with the traditional manual cleaning method, vibration cleaning can greatly improve the cleaning efficiency, save time and labor costs, and the vibration can make the sludge fall off from the filter press equipment more evenly, reduce the amount of residual sludge, improve the integrity of sludge discharge, and facilitate subsequent processing and disposal.

[0034] Furthermore, the sludge after filtration falls from the filter press plate 311 through the inclined surface of the lower material box 411 into the weighing box 412. The weighing box 412 is pushed downward by the weight of the sludge, and the pressure spring 417 is compressed under the push of the sliding pressure plate 415 on the surface of the weighing box 412. When the water content in the sludge is too high, the pressure spring 417 continuously compresses the sliding pressure plate 415 to contact the inclined push plate 416. Since the inclined push plate 416 has an inclined surface at one end and is located at Inside the sliding path of the sliding pressure plate 415, the sliding pressure plate 415 slides downward and contacts the inclined surface of the inclined push plate 416, thereby pushing the inclined push plate 416 to slide away from the weighing box 412. Since the inclined push plate 416 is fixedly connected to the unloading frame 419, the unloading frame 419 containing the chemical substances is pushed to slide toward the mixing box 2. Since the upper surface of the mixing box 2 is provided with a feeding trough, the lower surface of the unloading sealing plate 4110 is at the same level as the upper surface of the mixing box 2. When the feeding frame 419 is located at the feeding trough on the upper surface of the mixing box 2, the feeding sealing plate 4110 rotates around the side solid block 4111 on the surface of the feeding frame 419, so that the chemical substances inside the feeding frame 419 are fed into the mixing box 2 through the feeding trough on the surface of the mixing box 2, so that the tiny particles and colloidal substances in the sewage are condensed into larger flocs, which are easier to precipitate or be filtered, thereby improving the efficiency of solid-liquid separation in the filter pressing process. By observing the degree of descent of the weighing box 412 and comparing it with the normal sludge weight, the water content inside the sludge can be judged, and then the sewage can be adjusted, which solves the problem of whether the sludge after filter pressing is qualified and difficult to observe. In a way that is easy to observe, the sludge treatment results of each batch can be monitored to ensure the consistency and stability of the treatment effect, avoid the situation where the treatment does not meet the standards, and intuitively understand the treatment effect of the sludge. When the sludge is found to be unqualified, the filter pressing parameters, flocculant dosage and other treatment processes can be adjusted in time to improve the quality of sludge treatment.

[0035] Furthermore, after the detection mechanism 4 has detected whether the sludge is qualified, the electric telescopic rod on the surface of the fixed pull frame 414 pulls the bottom sealing plate 413 to slide away from the sliding pressure plate 415, and the bottom sealing plate 413 is separated from the bottom of the weighing box 412. The sludge inside the weighing box 412 enters the interior of the classification box 513 through the discharge box 411. When the sludge moisture content is qualified, the rotating shaft 516 is rotatably connected to the shaft groove on the surface of the No. 1 support 515. The left limiting pressure rod 514 is located at the top of the left rotating shaft 516 under the elastic force of the No. 4 spring 5110, thereby giving the rotating shaft 516 a The surface axis 516 is limited, and one end of the second support rod 518 is fixedly connected to the motor output shaft. The second support rod 518 is driven by the motor output shaft to rotate clockwise, thereby giving an upward force to the classification box 513 through the first support rod 517. Since the right rotating surface axis 516 is in an open state and the left rotating surface axis 516 is in a closed state, the first support rod 517 gives an upward force to the classification box 513, thereby pushing the classification box 513 to rotate counterclockwise around the rotating surface axis 516, so that the qualified sludge is poured into the left collection box 5112 for centralized collection; When the sludge moisture content is unqualified, the weighing box 412 slides downward under the push of the sludge's own gravity. As the degree of sliding down increases, the adjusting side plate 512 is driven to slide downward through the bottom sealing plate 413. Since one end of the adjusting side plate 512 is set as an inclined surface, and the inclined surface of the adjusting side plate 512 contacts the limiting pressure rod 514, the adjusting side plate 512 slides downward, thereby pushing the right limiting pressure rod 514 to slide through the inclined surface, thereby limiting the right rotating surface axis 516 through the right limiting pressure rod 514, and the left limiting pressure rod 514 slides away from the classification box 513 under the action of the pushing shaft on the surface of the connecting support rod 5111, thereby releasing the limit of the left rotating surface axis 516 by the left limiting pressure rod 514, and driving the No. 1 support rod 517 to rotate through the No. 2 support rod 518, thereby pushing the classification box 513 to rotate around the right rotating surface axis 516, thereby The unqualified sludge in the classification box 513 is pushed into the collection box 5112 on the right, and the qualified sludge and the unqualified sludge are classified and collected through the classification mechanism 5, which solves the problem of high moisture content in the sludge affecting subsequent treatment. The qualified sludge and the unqualified sludge are collected separately, and more appropriate treatment methods can be adopted for sludge of different properties. The qualified sludge can be directly disposed of or utilized in the subsequent treatment, and the unqualified sludge can be further treated or the process can be adjusted to improve its quality to meet the qualified standards. This can avoid unified treatment of all sludge and improve the overall treatment efficiency. In addition, classified collection helps to better monitor the quality of the sludge treatment process. Through the analysis of unqualified sludge, problems in the treatment process can be found, and process parameters can be adjusted in time to improve the quality stability of sludge treatment.
