Description

Technical Field

[0001] This invention relates to the field of sewage and sludge treatment technology, specifically to a sewage and sludge separation device. Background Technology

[0002] With the acceleration of urbanization and industrial development, sewage discharge is constantly increasing. In order to protect the environment and water resources, it is necessary to effectively treat sewage to remove pollutants and sludge. By using appropriate treatment methods, the water content and volume of sludge can be reduced, making it easier for subsequent treatment and disposal. However, 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 needs of sewage treatment, the research and development and application of sewage sludge separation devices have been carried out. By separating solid sludge from liquid in sewage, the content of suspended solids and pollutants in sewage is reduced, water quality is improved, and environmental protection requirements are met, so as to achieve the standard discharge of sewage.

[0003] The current equipment still has many inconveniences in its use;

[0004] The specific defects are as follows:

[0005] Firstly, due to the high viscosity of sludge and the uneven pressure distribution during the filtration process, sludge tends to adhere to the filter cloth or filter plates of the filter press, resulting in sludge residue. Existing cleaning methods typically involve manually pushing the filter plates to remove the sludge between them. However, manual cleaning is usually slow and cannot complete the removal of large amounts of sludge in a short time, thus affecting the progress of the entire wastewater treatment process. Furthermore, the quality of manual cleaning is easily affected by the individual skills and work attitude of the workers, resulting in incomplete cleaning. The sludge residue left on the filter press can clog the filter pores and affect the subsequent filtration effect.

[0006] Secondly, during the collection of sludge after filter pressing, uneven mixing of wastewater and sludge before filtration and uneven pressure distribution during the filtration process result in high moisture content in the sludge after filtration. Excessive moisture content increases the difficulty of subsequent treatment and disposal. For example, high moisture content increases transportation costs and can lead to leakage and environmental pollution during transport. Furthermore, using sludge with excessive moisture content for land improvement or landfill reduces soil permeability, affecting soil aeration and drainage, thus negatively impacting land use.

[0007] Therefore, the present invention proposes a sewage sludge separation device to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0023] (III) Beneficial Effects

[0024] The wastewater and sludge separation device provided by this invention has the following beneficial effects:

[0025] 1. By using the outer frame and vibration mechanism in conjunction, the filter press plate collides with the crossbars on the outer frame surface, generating vibration that shakes off the sludge adhering to the filter cloth on the filter press plate surface. This solves the problem of sludge adhering to the filter cloth or filter plate of the filter press equipment, which affects the filtration effect. 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 make the sludge fall off the filter press equipment more evenly, reducing the amount of residual sludge, improving the integrity of sludge discharge, and facilitating subsequent treatment and disposal.

[0026] 2. By using the mixing tank in conjunction with the testing mechanism, the descent of the weighing tank can be compared with the weight of normal sludge to determine the internal moisture content of the sludge. This allows for adjustments to the wastewater treatment process, solving the problem of difficulty in observing whether the sludge after filter pressing is up to standard. This easily observable method allows for monitoring the treatment results of each batch of sludge, ensuring consistency and stability of the treatment effect, avoiding substandard treatment, and providing a direct understanding of the sludge treatment effect. When unqualified sludge is found, the filter pressing parameters, flocculant dosage, and other treatment processes can be adjusted in a timely manner to improve the quality of sludge treatment.

[0027] 3. By combining testing and classification agencies, the classification agency separates qualified and unqualified sludge for collection. This solves the problem of high moisture content in the sludge affecting subsequent treatment. Separating qualified and unqualified sludge allows for more appropriate treatment methods based on their properties. Qualified sludge can be directly disposed of or utilized, while unqualified sludge can undergo further treatment or process adjustments to improve its quality and meet standards. This avoids uniform treatment of all sludge, improving overall treatment efficiency. Furthermore, separate collection facilitates better monitoring of sludge quality during treatment. Analysis of unqualified sludge can identify problems in the treatment process, allowing for timely adjustments to process parameters and improving the stability of sludge treatment quality.

[0028] 4. By using the vibration mechanism in conjunction with the detection mechanism, the sludge after filter pressing is shaken out of the filter press more thoroughly, avoiding sludge residue. The weight of the sludge is then measured, allowing the detection mechanism to more accurately reflect the actual sludge production. This helps to accurately monitor and manage the internal moisture content of the sludge during the wastewater treatment process. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] refer to Figures 1 to 12 A wastewater sludge separation device according to a preferred embodiment of the present invention will be described in detail below. The wastewater sludge separation device includes an outer frame 1, a mixing box 2 fixedly connected to the side of the outer frame 1, a vibration mechanism 3 for removing the sludge after pressure filtration from the device inside the outer frame 1, a detection mechanism 4 for detecting whether the sludge after pressure filtration is qualified, and a classification mechanism 5 for classifying the detected sludge inside the outer frame 1.

[0048] Vibration mechanism 3 includes a rising push rod 313 that provides vibration effect to the active device;

[0049] Testing facility 4 includes a weighing bin 412 for centralized storage of sludge;

[0050] The sorting mechanism 5 includes sorting bins 513 for sorting and placing sludge.

[0051] like Figure 2 , Figure 4 and Figure 5 As shown, the vibration mechanism 3 includes multiple filter plates 311. An electric telescopic rod is fixedly connected to the inner wall of the outer frame 1, and the electric telescopic rod is fixedly connected to the rightmost filter plate 311. A pneumatic device is provided on the surface of the outer frame 1, and the pneumatic device is connected to the interior of the leftmost filter plate 311. A supporting sliding shaft 312 is slidably connected inside the outer frame 1, and multiple filter plates 311 are slidably connected to the surface of the supporting sliding shaft 312. Pollutants inside the mixing tank 2 enter the interior of the filter plates 311 through conduits. Pressure is applied to the filter plates 311 by the pneumatic device. Under the pressure of the pneumatic device, the water inside the pollutants passes through the filter cloth inside the filter plates 311 and enters the liquid collection tank through the water outlet on the surface of the filter plates 311. The pollutants will remain on the surface of the filter cloth inside the filter plates 311, thus forming sludge blocks. When the pollutants inside the filter plates 311 are filtered, the filter plates 311 slide away from the mixing tank 2 under the pull of the electric telescopic rod. Figure 5 , Figure 6 and Figure 7 In the middle, the inner frame 1 has a sliding connection between a push spindle 314 and an adjustment spindle 316, and the inner part of the push spindle 314 has a sliding connection between a power slide shaft 319, such as... Figure 7In the middle, a locking block 3111 is fixedly connected to the surface of the power sliding shaft 319, and a third spring 3112 is fixedly connected to the surface of the locking block 3111. The third spring 3112 is fixedly connected to the push main shaft 314. A first spring 315 is fixedly connected to the side wall of the outer frame 1. The first spring 315 is fixedly connected to one end of the push main shaft 314. The filter plate 311 slides towards the first spring 315 under the pull of the electric telescopic rod. When the rightmost filter plate 311... The main shaft 314 contacts the filter press plate 311 and slides on the surface of the power slide shaft 319. The first spring 315 is compressed under the push of the main shaft 314. A third spring 3112 is fixedly connected between the main shaft 314 and the locking block 3111 on the surface of the power slide shaft 319. The main shaft 314 slides, while the power slide shaft 319 restricts the locking block 3111 through the locking support shaft 318. The third spring 3112 is compressed and stores energy under the push of the main shaft 314. A locking support shaft 318 is slidably connected inside the outer frame 1, and a second spring 317 is fixedly connected inside the outer frame 1. The second spring 317 is fixedly connected to the locking support shaft 318. An adjusting groove is provided on the surface of the locking support shaft 318. The adjusting main shaft 316 is slidably connected inside the adjusting groove on the surface of the locking support shaft 318. As the filter plate 311 continues to slide, the filter plate 311 and... The adjusting spindle 316 contacts and pushes it to slide towards the power slide shaft 319. Since one end of the adjusting spindle 316 has an inclined surface and the locking support shaft 318 has an adjusting groove inside, the inclined surface of the adjusting spindle 316 engages with the adjusting groove on the surface of the locking support shaft 318. The adjusting spindle 316 slides, thereby pushing the locking support shaft 318 upwards through the inclined surface, thus pushing the locking support shaft 318 out of the sliding path of the locking block 3111. Figure 8 In the middle, a fixed side plate 3114 is fixedly connected to the outer wall surface of the outer frame 1. A synchronous shaft 3115 is rotatably connected to the surface of the fixed side plate 3114. A synchronous gear 3113 and a rotating plate 3110 are fixedly connected to the surface of the synchronous shaft 3115. A toothed groove is formed on the surface of the power sliding shaft 319. The toothed blocks on the surface of the synchronous gear 3113 mesh with the toothed grooves 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 plate 3110. A fixed retaining shaft is fixedly connected to the surface of the outer frame 1. One end of the rising push rod 313 is rotatably connected to the surface of the fixed retaining shaft on the outer frame 1. Figure 4 and Figure 5In the middle, a support shaft 3116 is fixedly connected to the surface of the supporting slide shaft 312. The support shaft 3116 is L-shaped and located above the rising push rod 313. The support shaft 3116 is located inside the sliding path of the rising push rod 313. The power slide shaft 319 loses the restriction of the locking block 3111 by the locking support shaft 318. Under the push of the third spring 3112, the power slide shaft 319 slides towards the rotating plate 3110. Since the tooth groove on the surface of the power slide shaft 319 meshes with the synchronous gear 3113, the sliding of the power slide shaft 319 drives the synchronous gear 3113 to rotate, which in turn drives the locking block 3111 to rotate synchronously through the synchronous shaft 3115. Since one end of the rising push rod 313 is rotatably connected to the fixed locking shaft on the surface of the outer frame 1, and the other end of the rising push rod 313 is rotatably connected to the surface of the rotating plate 3110, the rotating plate 3110 rotates, thereby driving the upper... The lifting rod 313 rotates around the fixed shaft on the surface of the outer frame 1. Since the support shaft 3116 on the surface of the supporting slide shaft 312 is located inside the rotation path of the lifting rod 313, the lifting rod 313 rotates, thereby driving the supporting slide shaft 312 to slide upward through the support shaft 3116, thus 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 lifting rod 313 slides downward, and the support shaft 3116 loses the support of the lifting rod 313 and slides downward. The filter plate 311 collides with the crossbar on the surface of the outer frame 1, thereby generating vibration, which in turn shakes off 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 near the third spring 3112, and the locking shaft 318 is provided with an inclined surface on the side away from the third spring 3112. The locking shaft 318 is located inside the sliding path of the locking block 3111.

[0052] A further embodiment: A crossbar is provided on the surface of the outer frame 1, the crossbar on the surface of the outer frame 1 is located below the supporting slide shaft 312, and a sliding tie rod is provided between adjacent filter press plates 311.

[0053] The effect achieved by this embodiment is as follows: the crossbar on the surface of the outer frame 1 is located below the support slide shaft 312. When the support slide shaft 312 loses the support of the rising push rod 313 and slides downward, the filter plate 311 on the surface of the support slide shaft 312 collides with the crossbar on the surface of the outer frame 1 and thus generates vibration. The sliding tie rod between adjacent filter plates 311 ensures that the opening time of multiple filter plates 311 is equal when the electric telescopic rod is pulled, thereby ensuring the discharge space of sludge inside the filter plate 311.

[0054] like Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, Figure 2 and Figure 3In the process, the testing mechanism 4 includes a feeding 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 feeding 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 feeding box 411. The bottom sealing plate 413 is slidably connected to the inside of the fixed pull frame 414. An electric telescopic rod is installed inside the feeding box 411 and is fixedly connected to the surface of the fixed pull frame 414. Figure 9 and Figure 10 In the weighing box 412, a sliding pressure plate 415 is fixedly connected to the surface. A pressure spring 417 is fixedly connected inside the feeding box 411. The pressure spring 417 is fixedly connected to the lower surface of the sliding pressure plate 415. The sludge after pressing and filtering falls from the filter plate 311 and enters the weighing box 412 through the inclined surface of the feeding box 411. The weighing box 412 slides downward under the action of the sludge's own gravity, while the pressure spring 417 is compressed under the push of the sliding pressure plate 415 on the surface of the weighing box 412. A feeding frame 419 and an inclined push plate 416 are slidably connected inside the feeding box 411. The feeding frame 419 and the inclined push plate 416 are fixedly connected. A storage trough is opened inside the feeding box 411, and the storage trough inside the feeding box 411 is connected to the feeding frame 419. Figure 11 In the middle, a side fixing block 4111 is fixedly connected to the surface of the feeding frame 419, and a feeding sealing plate 4110 is rotatably connected to the surface of the side fixing block 4111. The upper surface of the feeding sealing plate 4110 is in contact with the lower surface of the feeding frame 419, such as... Figure 10In the middle, a restoring spring 418 is fixedly connected inside the feeding 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, which is located inside the sliding path of the sliding pressure plate 415. When the water content in the sludge is too high, the pressure spring 417 continuously compresses the sliding pressure plate 415 and contacts 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 and contacts the inclined surface of the inclined push plate 416, thereby pushing the inclined push plate 416 further. The material box 419 slides away from the weighing box 412. Since the inclined push plate 416 is fixedly connected to the feeding frame 419, it pushes the feeding frame 419 containing chemical substances to slide closer to the mixing box 2. The upper surface of the mixing box 2 is provided with a feeding trough. The lower surface of the feeding sealing plate 4110 is at the same level as the upper surface of the mixing box 2. When the feeding frame 419 is located in the feeding trough on the upper surface of the mixing box 2, the feeding sealing plate 4110 rotates around the side fixing block 4111 on the surface of the feeding frame 419, thereby feeding the chemical substances inside the feeding frame 419 into the interior of the mixing box 2 through the feeding trough on the surface of the mixing box 2. This causes the tiny particles and colloidal substances in the sewage to agglomerate into larger flocs, which are easier to settle or filter.

[0055] like Figure 2 , Figure 3 and Figure 12 As shown, Figure 2 and Figure 3 In the classification mechanism 5, a fixed base plate 511 is fixedly connected to the inside of the outer frame 1. Four first supports 515 and two second supports 519 are fixedly connected to the upper surface of the fixed base plate 511. Figure 12In this structure, the surface of support 515 is provided with a retaining groove, and a limiting rod 514 is slidably connected inside support 515. The limiting rod 514 is L-shaped. Support 519 is rotatably connected to support rod 518, and one end of support rod 518 is rotatably connected to support rod 517. The sorting box 513 is rotatably connected to one end of support rod 517. Four rotating shafts 516 are fixedly connected to the surface of sorting box 513. The rotating shafts 516 are slidably connected inside the retaining groove on the surface of support 515. Connecting rods 5111 are fixedly connected between adjacent limiting rods 514, and a pushing shaft is fixedly connected between two connecting rods 5111. When the sludge moisture content is qualified, the rotating shafts 516 are rotatably connected to support 519. Surface groove 515, left limiting pressure rod 514 is located at the top of left rotating shaft 516 under the elastic force of spring 5110, thus limiting rotating shaft 516. One end of second support rod 518 is fixedly connected to motor output shaft. Driven by motor output shaft, second support rod 518 rotates clockwise, thus applying an upward force to sorting box 513 through first support rod 517. Since right rotating shaft 516 is in the open state and left rotating shaft 516 is in the closed state, the upward force applied by first support rod 517 to sorting box 513 pushes sorting box 513 to rotate counterclockwise around rotating shaft 516, thus pouring qualified sludge into left collection box 5112 for centralized collection. Discharge box 411 An adjusting side plate 512 is slidably connected to the bottom of the bottom sealing plate 413. A limiting pressure rod 514 is on the same vertical plane as the adjusting side plate 512. A fourth spring 5110 is fixedly connected to the surface of the first support 515 on the right side. The fourth spring 5110 is fixedly connected to the right limiting pressure rod 514. Two collection boxes 5112 are fixedly connected to the upper surface of the fixed base plate 511. The two collection boxes 5112 are symmetrically arranged on both sides of the sorting box 513. The first support rod 517 and the second support rod 518 are of equal length, and their lengths are greater than half the side length of the sorting box 513. When the sludge moisture content is unqualified, the weighing box 412 is pushed by the sludge's own weight. As the slide downwards, the bottom sealing plate 413 drives the adjusting side plate 512 to slide downwards. 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 downward sliding of the adjusting side plate 512 pushes the right limiting pressure rod 514 to slide, thereby limiting the right rotating shaft 516 through the right limiting pressure rod 514. Meanwhile, the left limiting pressure rod 514 slides away from the sorting box 513 under the action of the pushing shaft on the surface of the connecting support rod 5111, thereby releasing the left limiting pressure rod 514 from limiting the left rotating shaft 516. The second support rod 518 drives the first support rod 517 to rotate, thereby pushing the sorting box 513 to rotate around the right rotating shaft 516.This pushes the substandard sludge inside sorting bin 513 into collection bin 5112 on the right.

[0056] A 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 under the push of the adjusting side plate 512, and when the right limiting pressure rod 514 completely limits the right rotating shaft 516, the position of the limiting pressure rod 514 is fixed by the limiting block.

[0057] The effect achieved by this embodiment is as follows: it prevents the sorting box 513 from returning to the state of feeding material into the collection box 5112 on the left side, which contains qualified sludge, under the elastic force of the fourth spring 5110.

[0058] The following is the complete working process and working principle of the above embodiments:

[0059] Initially: the rising push rod 313 is located below the horizontal bar on the surface of the outer frame 1, 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 block 3111 and the locking support shaft 318 is located on the right side of the locking block 3111, the first 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 discharge frame 419 is aligned with the discharge port of the storage tank inside the discharge box 411, the left rotating shaft 516 is in a limited state, and the right rotating shaft 516 is in an active state.

[0060] During operation: Pollutants inside the mixing tank 2 enter the filter press plate 311 through a conduit. A pneumatic device applies pressure to the filter press plate 311. Under this pressure, moisture inside the pollutants passes through the filter cloth inside the filter press plate 311 and enters the liquid collection tank through the outlet on the surface of the filter press plate 311. The pollutants remain on the surface of the filter cloth inside the filter press plate 311, forming sludge. Once the pollutants inside the filter press plate 311 have been filtered, the filter press plate 311 slides towards the first spring 315 under the pull of the electric telescopic rod. When the rightmost filter press plate 311 contacts the drive shaft 314, the drive shaft 314 slides on the surface of the power sliding shaft 319 under the push of the filter press plate 311. The first spring 315 is compressed under the push of the drive shaft 314. Due to the contact between the drive shaft 314 and the power sliding shaft 319... A third spring 3112 is fixedly connected between the face-locking blocks 3111, which pushes the main shaft 314 to slide. The power slide shaft 319 restricts the locking blocks 3111 through the locking support shaft 318. Thus, the third spring 3112 is compressed and stores force under the push of the main shaft 314. As the filter plate 311 continues to slide, the filter plate 311 contacts the adjusting main shaft 316, thereby pushing the adjusting main shaft 316 to slide towards the power slide shaft 319. Since one end of the adjusting main shaft 316 is provided with an inclined surface and the locking support shaft 318 is provided with an adjusting groove, the inclined surface of the adjusting main shaft 316 fits with the adjusting groove on the surface of the locking support shaft 318. The adjusting main shaft 316 slides, thereby pushing the locking support shaft 318 to slide upward through the inclined surface, thereby pushing the locking support shaft 318 away from the sliding path of the locking blocks 3111.

[0061] Meanwhile, the power slide shaft 319 loses the restriction of the locking support shaft 318 on the locking block 3111. Under the push of the third spring 3112, the power slide shaft 319 slides towards the rotating plate 3110. Since the tooth groove on the surface of the power slide shaft 319 meshes with the synchronous gear 3113, the sliding of the power slide shaft 319 drives the synchronous gear 3113 to rotate, which in turn drives the locking block 3111 to rotate synchronously through the synchronous shaft 3115. Since one end of the rising push rod 313 is rotatably connected to the fixed locking shaft on the surface of the outer frame 1, and the other end of the rising push rod 313 is rotatably connected to the surface of the rotating plate 3110, the rotation of the rotating plate 3110 drives the rising push rod 313 to rotate around the fixed locking shaft on the surface of the outer frame 1. Since the surface support shaft 3116 of the support slide shaft 312 is located inside the rotation path of the rising push rod 313, the rotation of the rising push rod 313 drives the support slide shaft through the surface 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 shaft 3116 loses the support of the rising push rod 313 and slides downward. The filter plate 311 collides with the crossbar on the surface of the outer frame 1, thereby generating vibration, which shakes off the sludge attached to the filter cloth on the surface of the filter plate 311. This solves the problem of sludge attached to the filter cloth or filter plate of the filter press equipment, which affects the filter pressing effect. 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 the traditional manual cleaning method, vibration cleaning can greatly improve cleaning efficiency, save time and labor costs, and vibration can make the sludge fall off the filter press equipment more evenly, reduce the amount of residual sludge, improve the integrity of sludge discharge, and facilitate subsequent treatment and disposal.

[0062] Furthermore, the sludge after filter pressing falls from the filter press plate 311 through the inclined surface of the feed box 411 into the weighing box 412. Under the weight of the sludge itself, the weighing box 412 slides downwards, while the pressure spring 417 is compressed by the sliding pressure plate 415 on the surface of the weighing box 412. When the moisture content in the sludge is too high, the pressure spring 417 continues to compress the sliding pressure plate 415 into contact with the inclined push plate 416. Since one end of the inclined push plate 416 is provided with an incline and is located at... Inside the sliding path of the sliding pressure plate 415, the sliding pressure plate 415 slides downwards 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 feeding frame 419, it pushes the feeding frame 419 containing the chemical substance to slide closer to the mixing box 2. Since the upper surface of the mixing box 2 is provided with a feeding trough, the lower surface of the feeding sealing plate 4110 is at the same level as the upper surface of the mixing box 2. When the feeding frame 419 is located in the feeding trough on the upper surface of the mixing tank 2, the feeding sealing plate 4110 rotates around the side fixing block 4111 on the surface of the feeding frame 419, thereby feeding the chemical substances inside the feeding frame 419 into the interior of the mixing tank 2 through the feeding trough on the surface of the mixing tank 2. This causes the tiny particles and colloidal substances in the sewage to agglomerate into larger flocs. These flocs are easier to settle or filter, thereby improving the efficiency of solid-liquid separation in the filter press process. By observing the degree of descent of the weighing tank 412 and comparing it with the normal sludge weight, the water content inside the sludge can be determined, and the sewage can be adjusted accordingly. This solves the problem of not being able to easily observe whether the sludge after filter press is qualified. Through an easy-to-observe method, the treatment results of each batch of sludge can be monitored to ensure the consistency and stability of the treatment effect, avoid the occurrence of substandard treatment, and intuitively understand the treatment effect of the sludge. When the sludge is found to be unqualified, the filter press parameters, flocculant dosage, and other treatment processes can be adjusted in time to improve the quality of sludge treatment.

[0063] Furthermore, after the testing agency 4 has tested whether the sludge is qualified, it pulls the bottom sealing plate 413 away from the sliding pressure plate 415 by the electric telescopic rod on the surface of the fixed pull frame 414. The bottom sealing plate 413 disengages from the bottom of the weighing box 412, and the sludge inside the weighing box 412 enters the interior of the sorting box 513 through the feeding box 411. When the sludge moisture content is qualified, because the rotating shaft 516 is rotatably connected to the shaft groove on the surface of the first 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 fourth spring 5110, thereby giving rotation... The rotating shaft 516 is restricted, and one end of the second support rod 518 is fixedly connected to the motor output shaft. Driven by the motor output shaft, the second support rod 518 rotates clockwise, thereby giving the sorting box 513 an upward force through the first support rod 517. Since the right rotating shaft 516 is in the open state and the left rotating shaft 516 is in the closed state, the first support rod 517 gives the sorting box 513 an upward force, thereby pushing the sorting box 513 to rotate counterclockwise around the rotating shaft 516, thereby pouring the qualified sludge into the left collection box 5112 for centralized collection.

[0064] When the sludge moisture content is unqualified, the weighing box 412 slides downward under the force of the sludge's own weight. As the downward movement increases, the bottom sealing plate 413 drives the adjusting side plate 512 to slide downward. 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 downward sliding of the adjusting side plate 512 pushes the right limiting pressure rod 514 to slide, thereby limiting the right rotating shaft 516 through the right limiting pressure rod 514. Meanwhile, the left limiting pressure rod 514 slides away from the sorting box 513 under the action of the pushing shaft on the surface of the connecting support rod 5111, thereby releasing the left limiting pressure rod 514 from limiting the left rotating shaft 516. The second support rod 518 drives the first support rod 517 to rotate, thereby pushing the sorting box 513 to rotate around the right rotating shaft 516. Unqualified sludge inside the sorting bin 513 is pushed into the collection bin 5112 on the right. The sorting mechanism 5 separates and collects qualified and unqualified sludge, solving the problem of high moisture content in the sludge affecting subsequent treatment. Separating qualified and unqualified sludge allows for more appropriate treatment methods for sludge of different properties. Qualified sludge can be directly disposed of or utilized, while unqualified sludge can undergo further treatment or process adjustments to improve its quality and meet the qualified standards. This avoids uniform treatment of all sludge, improving overall treatment efficiency. Furthermore, separate collection helps to better monitor the quality of sludge treatment. By analyzing unqualified sludge, problems in the treatment process can be identified, and process parameters can be adjusted in a timely manner to improve the quality stability of sludge treatment.
