Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a sludge purification system and method. Background Technology

[0002] The mud left behind by the flood has a significant impact on the disaster victims. Because the low-lying areas were completely submerged after the flood, the houses of the residents in the disaster area were mostly covered with mud that was everywhere and difficult to completely remove. Large mud cleaning equipment could not completely remove the mud from the houses and yards, especially in rural areas. It was time-consuming and laborious for residents to clean up the mud themselves, and it was also difficult to process the mud that was cleaned up, making it difficult to immediately carry out post-disaster reconstruction work in farmland and other locations. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a sludge purification system and method, the beneficial effect of which is that the present invention can easily treat the sludge left in the courtyards of rural residents after floods.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A sludge purification system includes a housing, inside which a drainage mechanism, a mixing mechanism, and a water tank are installed. A suction mechanism and a flushing mechanism are connected to the housing via connecting pipes.

[0006] The suction mechanism can replace the suction head according to the actual sludge condition.

[0007] The rinsing mechanism can be manually adjusted to change the amount and ratio of rinsing water.

[0008] The drainage mechanism includes a drainage plate that is slidably connected to the shell, a drainage box that is sleeved on the outside of the drainage plate, a sludge pump that is installed on the right side of the drainage box, the drainage box and the sludge pump that are fixed to the shell, a push plate that is slidably connected to the upper side of the drainage box, a drainage block that is installed on the upper side of the drainage box, and the drainage block that is slidably connected to the upper side of the shell via a T-shaped track.

[0009] A sludge purification system includes a process for sludge purification, comprising the following steps:

[0010] a: Introduce clean water into the water tank through the connecting pipe, and load the processed straw and weeds into the storage bin;

[0011] b: Move the sludge purification system to the location where sludge cleaning and purification are required;

[0012] c: The sludge is cleaned using a suction system;

[0013] d: The sludge is initially separated through a drainage system, resulting in preliminarily separated sludge and turbid water;

[0014] e: The sludge after preliminary separation is introduced into the mixing mechanism to mix the sludge after preliminary separation with the treated straw and weeds;

[0015] f: The mixed sludge is separated a second time by a mixing mechanism to obtain sludge cake and turbid water;

[0016] g: Pour the turbid water produced in steps d and f into the water tank and remove the mud cake;

[0017] h: Open the flushing mechanism and use turbid water and clean water to flush the area that needs to be cleaned and purified by the flushing mechanism;

[0018] i: Repeat steps c to h until the sludge purification process is complete. Attached Figure Description

[0031] like Figures 3 to 6 As shown:

[0032] A sludge purification system includes a housing 100, inside which a drainage mechanism 200, a mixing mechanism 300, and a water tank 110 are installed. A suction mechanism and a flushing mechanism are connected to the housing 110 via connecting pipes. The drainage mechanism 200 and the mixing mechanism 300 are both connected to the water tank 110 via connecting pipes. The water tank 110 is connected to the outside via connecting pipes. The interior of the water tank 110 is divided into two cavities by a partition.

[0033] When it is necessary to clean sludge accumulated in the yard or indoors, the user can first fill the water tank 110 with clean water through the connecting pipe, and then load the treated straw or weeds into the mixing mechanism 300. The sludge purification system can then be moved to an area close to the location to be cleaned. The suction mechanism can be removed, and the drainage mechanism 200 can be activated. The suction mechanism will then clean the sludge, allowing it to pass through the suction mechanism into the drainage mechanism 200. Activating the drainage mechanism 200 will then perform preliminary separation of the sucked-in sludge, allowing it to be properly separated. The turbid water in the sludge can enter the water tank 110 through the connecting pipe, and then the sludge that has completed the initial separation can be introduced into the mixing mechanism 300, so that the sludge that has completed the initial separation can be mixed with the treated straw or weeds. Then the mixing mechanism 300 can be activated, so that the sludge mixed with the treated straw or weeds can be separated a second time, so that the turbid water in the sludge mixed with the treated straw or weeds can be separated again and enter the water tank 110 through the connecting pipe. At the same time, mud cakes can be obtained by pressing the sludge mixed with the treated straw or weeds, thus completing the sludge treatment and purification work.

[0034] Meanwhile, after the sludge treatment is completed, the user can open the mixing mechanism 300 to take out the pressed mud cake. Since the sludge generated by natural disasters such as floods is mainly natural sludge, it contains less heavy metals and other polluting impurities. Therefore, after being mixed with straw or weeds, it can be directly used as compost material or soil fertilizer in the field. Since the mud cake has less moisture and contains straw or weeds as internal support, the user can easily take out the mud cake from the mixing mechanism 300. The mud cake can be conveniently stacked or spread out to dry, which facilitates the user's secondary treatment of the sludge purification products.

[0035] Secondly, when the sludge to be cleaned has dried on the surface and cannot be sucked up or cleaned, the flushing mechanism can be removed and activated. The flushing mechanism can then use clean or turbid water from the water tank 110 to soak the sludge, softening it and making it easier for the suction mechanism to suck it up. Furthermore, when a small amount of sludge still adheres to the surface and is inconvenient to wipe manually, the flushing mechanism can use clean water from the water tank 110 to rinse the remaining sludge, thus completely cleaning and removing the sludge from the surface and restoring it to a clean state.

[0036] Because the water tank 110 can be divided into two cavities by a partition, it can separate turbid water from clean water. When it is necessary to soak or clean sludge, different stored water can be discharged for use, thereby saving water resources used for soaking sludge as much as possible, while effectively ensuring the cleanliness of the surface to be cleaned after rinsing.

[0037] Further:

[0038] The suction mechanism can change the suction head according to the actual sludge condition; thus, it is convenient for users to hold the suction mechanism to suck up and clean sludge, and the suction head can be adapted to more complex and narrow areas, so as to further complete the sludge cleaning work on the surface to be cleaned.

[0039] Further:

[0040] The rinsing mechanism can be manually adjusted to control the amount and ratio of rinsing water. This allows users to manually control and adjust the ratio of clean water to turbid water in the rinsing water, and also adjust the rinsing intensity. When cleaning soft surfaces, it can prevent secondary damage to the surfaces to be cleaned.

[0041] like Figures 7 to 8 As shown:

[0042] The drainage mechanism 200 includes a drainage plate 220, which is slidably connected to the housing 100 via an electric push rod A. A drainage box 210 is sleeved on the outside of the drainage plate 220. A mud pump 250 is provided on the right side of the drainage box 210. Both the drainage box 210 and the mud pump 250 are connected to the housing 100 via screws. A push plate 240 is slidably connected to the upper side of the drainage box 210 via an electric push rod B. A drainage block 230 is provided on the upper side of the drainage box 210. The drainage block 230 is slidably connected to the upper side of the housing 100 via a T-shaped track.

[0043] When the suction mechanism needs to suck sludge into the drainage mechanism 200, the sludge pump 250 can be started. The sludge to be cleaned, aligned with the suction mechanism, is sucked into the drainage tank 210 through the connecting pipe by the sludge pump 250. Then, the drainage block 230 can be moved to the upper side of the drainage tank 210 by the T-shaped track. The drainage block 230 can be started to move downward and contact the drainage tank 210. Then, the extension rod of the electric push rod A can be extended, thereby driving the drainage plate 220 to move upward. The drainage plate 220 can drive the sludge inside to move upward, thereby squeezing the sludge inside through the drainage tank 210 and the drainage plate 220. This allows the turbid water in the sludge to be discharged through the drainage block 230, thus completing the initial separation of the sucked sludge.

[0044] Meanwhile, since the sludge contains a lot of mud and sand, it is easy for the mud and sand to clog the drainage block 230. After one squeeze filtration is completed, the drainage block 230 can be controlled to move upward, and then the telescopic rod of the electric push rod B can be controlled to extend. This allows the push plate 240 to move to the right through the electric push rod B, so that the push plate 240 can scrape the lower surface of the drainage block 230. This ensures that the filtration and drainage function of the drainage block 230 is not affected by mud and sand clogging. At the same time, the scraped sludge can be pushed into the mixing mechanism 300 by the push plate 240. Then the above squeeze filtration work can be repeated until all the sludge that has completed the initial separation can enter the mixing mechanism 300.

[0045] Meanwhile, since the drainage block 230 is located on the upper side of the drainage tank 210, when the drainage block 230 is moved upward, the sludge that still contains a lot of water can fall under the action of gravity, thereby preventing the sludge containing a lot of water from being pushed into the mixing mechanism 300 by the push plate 240, which would result in poor initial separation of the sludge.

[0046] like Figure 9 As shown:

[0047] The drainage block 230 includes an electrically controlled telescopic rod 231, a flow guide pump 232 is fixedly connected to the telescopic rod of the electrically controlled telescopic rod 231, the flow guide pump 232 is fixedly connected to the flow guide shell 233, a water suction block 234 is fixedly connected inside the flow guide shell 233, a water filter layer 235 is fixedly connected to the lower side of the water suction block 234, and the flow guide pump 232 is connected to the water tank 110 through a connecting pipe.

[0048] When it is necessary to use the drainage block 230 to separate the sludge in the drainage tank 210, the electrically controlled telescopic rod 231 can be extended, thereby causing the electrically controlled telescopic rod 231 to drive the guide shell 233 to descend, so that the guide shell 233 contacts the drainage tank 210, thereby preventing the sludge in the drainage tank 210 from leaking from the edge of the guide shell 233; then the guide pump 232 can be started, thereby sucking up the sludge in contact with the filter layer 235, so that the turbid water can pass through the filter layer 235 and the suction block 234, and enter the water tank 110 through the connecting pipe, thereby completing the separation of turbid water from the sludge in the drainage tank 210.

[0049] Further:

[0050] The water-absorbing block 234 has a porous sponge-like structure, and the filter layer 235 has a smooth surface and a fine mesh structure; thus, the turbid water in the sludge can be filtered through the water-absorbing block 234, while the filter layer can remove larger particles of mud and sand to the outside of the water-absorbing block 234, preventing the water-absorbing block 234 from being blocked by larger particles of mud and sand.

[0051] like Figure 10 As shown:

[0052] The mixing mechanism 300 includes a mixing box 310, a storage box 320 is provided on the rear side of the mixing box 310, the mixing box 310 is slidably connected to the box shell 100 by an electrically controlled slide table, the storage box 320 is connected to the box shell 100 by screws, and a mixing block 330 is slidably connected to the upper side of the storage box 320 by a T-shaped track.

[0053] Before the mixing mechanism 300 needs to mix sludge with straw or weeds, the mixing box 310 can be moved to the left by the electric slide table, so that the mixing box 310 fits into the drainage box 210. This allows the sludge pushed out to the right by the push plate 240 to fall completely into the mixing box 310, preventing the sludge, which still contains moisture, from leaking from the edge of the drainage box 210 and thus contaminating the sludge purification system.

[0054] When the mixing mechanism 300 needs to mix sludge with straw or weeds, the mixing box 310 can be returned to its original position by controlling the electric slide table to avoid interference when the mixing mechanism 300 is mixing sludge with straw or weeds; then the mixing block 300 is controlled to move above the storage box 320 via the T-shaped track, and then the mixing block 300 is activated, so that the mixing block 300 can grab the straw or weeds inside the storage box 320 and move the straw or weeds into the mixing box 310. Then the mixing block 300 can be controlled to rotate, so that the sludge and straw or weeds can be rotated, thereby completing the mixing.

[0055] When secondary separation of the mixed sludge is required, the drainage block 230 can be controlled to move via the T-shaped track, thereby moving the drainage block 230 to the upper side of the mixing box 310. Then, the drainage block 230 can be restarted to perform secondary separation of the mixed sludge. This completely removes the turbid water components from the mixed sludge and presses the remaining sludge mixed with straw or weeds into a removable mud cake, thus completing the secondary separation of the mixed sludge.

[0056] like Figure 11 As shown:

[0057] The mixing block 330 includes a mixing plate 331, which is slidably connected to a T-shaped track via an electric push rod C. A gripping block 332 is rotatably connected to the lower side of the mixing plate 331 via the output shaft of a rotary motor. Multiple gripping claws 333 are hinged on the gripping block 332.

[0058] When it is necessary to grab straw or weeds, the mixing block 330 can be moved above the storage box 320 via the T-shaped track. Then, the electric push rod C is extended, so that the grabbing claw 333 can grab the straw or weeds via the grabbing block 332. Then, the electric push rod C is shortened, and the mixing plate 331 is moved above the mixing box 310 via the T-shaped track. Then, the straw or weeds can be put into the mixing box 310 via the grabbing block 332, so that the straw or weeds can be mixed with the sludge in the mixing box 310.

[0059] When it is necessary to mix sludge with straw or weeds, the electric push rod C can be extended, thereby causing the mixing plate 331 to move the gripping block 332 and gripping claw 333 to a suitable position. Then, the rotary motor can be started, thereby driving the gripping block 332 to rotate through the output shaft of the rotary motor. In turn, the gripping block 332 drives the gripping claw 333 to rotate, thereby driving the sludge and straw or weeds inside the mixing box 310 to mix through the gripping claw 333, thus completing the mixing of sludge with straw or weeds.

[0060] like Figure 4 As shown:

[0061] Multiple wheels 120 are rotatably connected to the bottom of the housing 100; this allows the sludge purification system to be moved easily, thereby reducing the difficulty for users to move the sludge purification system independently and facilitating the expansion of the application range of the sludge purification system.

[0062] A sludge purification system includes a process for sludge purification, comprising the following steps:

[0063] a: Introduce clean water into the water tank 110 through the connecting pipe, and load the processed straw and weeds into the storage bin 320;

[0064] b: Move the sludge purification system to the location where sludge cleaning and purification are required;
