Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sludge and sewage separation and treatment device. BACKGROUND

[0002] In many scenes such as industrial production, municipal sewage treatment, river dredging and environmental governance, efficient separation of sludge and sewage is a core link to realize pollution reduction and harmless disposal, which is directly related to the subsequent water treatment efficiency, sludge disposal cost and feasibility of resource utilization. As a current mainstream sludge dewatering equipment, the screw filter press is widely used in solid-liquid separation field due to its relatively simple structure and convenient operation. Its core working principle is to push the material through the screw shaft and form an extrusion space with the variable diameter filter cartridge to realize sludge dewatering.

[0003] However, with the continuous improvement of environmental protection requirements and the growth of processing demand, the traditional screw filter press has exposed many technical defects that are difficult to avoid in actual application. The traditional screw filter press adopts a direct continuous feeding mode, and a large amount of free water in the sewage directly enters the filter pressing link without preliminary separation, which greatly increases the dewatering load of the screw filter press and prolongs the filter pressing cycle. Moreover, due to the limitation of the single extrusion dewatering mode, the moisture content of the sludge finally discharged by the traditional screw filter press is generally high (usually up to 60%-70%), which not only leads to large volume and strong flowability of the sludge, increasing the leakage risk and transportation cost in the transportation process, but also occupies more land resources during subsequent landfill disposal. The traditional screw filter press lacks an effective grading purification process for the wastewater generated after filter pressing. These wastewaters still contain impurities such as fine suspended particles and soluble pollutants. If directly discharged, it will cause secondary pollution to the surrounding water and soil. If an independent wastewater treatment equipment is additionally configured, it will lead to scattered overall treatment process, large land occupation, increased investment cost, and difficulty in realizing integrated efficient treatment. Therefore, it is necessary to provide a sludge and sewage separation and treatment device to solve the above technical problems. SUMMARY

[0013] Preferably, among the plurality of filter plates, the filter pore diameter of the upper filter plate is larger than that of the filter plate below it.

[0014] Preferably, the four sewage inlets and the four sewage outlets are staggered, and the four sewage outlets are respectively arranged in a one-to-one correspondence with the four partition chambers.

[0015] Compared with related technologies, the sludge-sewage separation and treatment device provided by the present invention has the following beneficial effects:

[0016] 1. In the feeding component of the solid-liquid separation unit of this invention, the distribution disc, through four circumferentially arrayed partition chambers, in conjunction with the intermittent rotation of the driven shaft, achieves simultaneous operation of four stations: "sludge receiving, water filtration, sludge discharge, and cleaning." The preliminary water filtration reduces the working pressure of the filter press component. The air pump of the air extraction component draws air from the water filtration chamber through the air extraction pipe to form a negative pressure, accelerating the permeation of sewage through the arc-shaped filter plate. At the same time, the extracted air is discharged into the cleaning chamber through the exhaust pipe, forming a positive airflow that back-blown the corresponding arc-shaped filter plate, reducing the risk of clogging of the filter holes of the arc-shaped filter plate corresponding to the cleaning chamber, facilitating the subsequent continuous use of the arc-shaped filter plate, thereby reducing maintenance costs and ensuring continuous operation. Through the preliminary filtration of the arc-shaped filter plate, free water in the sewage is quickly separated, allowing the sludge sewage to be concentrated in advance, so that the subsequent pressing does not need to contend with a large amount of free water, thereby reducing the dewatering load of the subsequent filter press component and improving the dewatering effect.

[0017] 2. The conveying cylinder of the filter press adopts a variable diameter structure with the cylinder diameter gradually decreasing from the middle to the outlet end. Together with the spiral blades on the horizontal shaft, it forms a progressive compression of the sludge falling into the first discharge bucket. The clamping plate at the outlet end of the conveying cylinder forms an elastic clamping mechanism through the sliding rod and spring, which forms a reverse pressure. This pressure works in conjunction with the thrust of the spiral blades to compact and dewater the sludge. The precipitated water flows into the water receiving bucket through the sludge discharge filter plate and finally into the water filtration unit, thereby making the sludge dewatering more thorough, significantly reducing the moisture content, and greatly reducing the difficulty of subsequent treatment.

[0018] 3. The transmission components, through the meshing of worm gears and worm wheels, convert the horizontal rotation output of the drive motor into the vertical rotation of the drive shaft, thereby achieving multi-component linkage: including the drive disc engaging with the actuating groove of the transmission disc through an eccentric column, driving the driven shaft to rotate intermittently, synchronously controlling the switching of the material distribution disc position and the opening and closing of the upper and lower valve plates of the feeding unit; also including the drive shaft driving the scraper of the water filtration unit to rotate, thereby scraping the impurities trapped at the top of the filter plate into the sewage discharge channel, achieving automatic cleaning.

[0019] 4. In the sludge feeding component of the feeding unit, the sludge inlet of the upper valve plate and the sludge outlet of the lower valve plate are staggered, and the sludge outlets correspond one-to-one with the partition chambers of the distribution plate. When the driven shaft rotates intermittently, the upper valve plate periodically connects the third discharge hopper and the sludge storage tank, and the lower valve plate periodically connects the sludge storage tank and the partition chamber, achieving quantitative feeding. Specifically, when the sludge inlet is directly opposite the third discharge hopper and the third discharge hopper is fully connected to the sludge storage tank, the lower valve plate blocks the sludge storage tank, allowing sludge to be added to the tank. When the sludge outlet is fully connected to the sludge storage tank, the upper valve plate blocks the third discharge hopper, thus stopping the addition of sludge to the tank. At this time, the sludge in the tank is added to the partition chamber below. Simultaneously, the mixing motor of the mixing component drives the mixing paddle shaft to rotate, preventing sludge from settling and clumping. This solves the problem of filtration load imbalance caused by uneven feeding, ensures more consistent processing conditions in each partition chamber, and improves the stability of the separation effect.

[0020] 5. The filter box of the water filtration unit is equipped with several filter plates arranged from top to bottom, and the filter hole diameter of the upper filter plate is larger than that of the lower filter plate, so as to realize the graded purification from coarse filtration to fine filtration; the drive shaft drives the scraper to rotate, scraping the impurities trapped on the filter plate to the sewage discharge channel to prevent the filter plate from clogging; the filter box simultaneously receives the preliminary filtered water from the second discharge hopper and the dewatered wastewater from the receiving hopper, and carries out multi-stage purification in a centralized manner. Finally, the purified clean water is discharged through the drain pipe, which improves the sewage purification effect and realizes automatic removal of impurities, reducing manual intervention.

[0021] 6. This invention integrates the solid-liquid separation unit, feeding unit, and water filtration unit into a single unit using a support frame, enabling continuous operation of wastewater feeding, preliminary filtration, deep sludge dewatering, and multi-stage wastewater purification. This solves the defects of existing devices, such as dispersed processes and low integration. The units work closely together, eliminating the need to transfer intermediate materials and improving the overall efficiency of wastewater treatment. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Please refer to the following: Figures 1 to 7A sludge and wastewater separation and treatment device includes a support frame 1. A solid-liquid separation unit 2, a feeding unit 3, and a filtration unit 4 are mounted on the frame wall of the support frame 1. The solid-liquid separation unit 2 includes a feeding component 21, an air extraction component 22, a filter press component 23, and a transmission component 24. The feeding component 21 includes a cylinder 211. A cleaning chamber 2111 and a filtration chamber 2112 are respectively provided on both sides of the cylinder 211. A first discharge hopper 2113 and a second discharge hopper 2114 are connected to the bottom of the cylinder 211. The second discharge hopper 2114 is directly opposite the filtration chamber 2112. The cylinder 211 is vertically rotatably connected to a driven shaft 215. A distribution plate 212 is fixedly sleeved on the outside of the driven shaft 215. Four partition chambers 213 are arranged in a circular array on the distribution plate 212. Four arc-shaped filter plates 214, corresponding one-to-one with the partition chambers 213, are fixedly connected to the outside of the partition chambers 213. The cylinder 211 is fixedly connected to the wall of the support 1. The feeding unit 3 is used to quantitatively transport sewage to the solid-liquid separation unit 2. The water filtration unit 4 is used to filter the water discharged from the solid-liquid separation unit 2.

[0037] In the above, the bottom surface of the distribution plate 212 is fitted with a corrosion-resistant rubber sealing gasket, and the bottom surface slides against the inner bottom surface of the cylinder 211; the side surface of the distribution plate 212 is also fitted with a corrosion-resistant rubber sealing gasket, and its outer side slides against the inner wall of the cylinder 211 to ensure good sealing; the bracket 1 serves as the overall installation base, realizing the integrated construction of the solid-liquid separation unit 2, the feeding unit 3, and the water filtration unit 4, providing stable support for the coordinated operation of each unit; the cylinder 211 of the feeding component 21 is designed with partitions of the cleaning chamber 2111 and the water filtration chamber 2112. The first discharge hopper 2113 and the second discharge hopper 2114 are respectively used to guide the sludge and water after preliminary filtration. The four circumferential array partition cavities 213 of the distribution plate 212, in conjunction with the rotation of the driven shaft 215, can simultaneously realize multi-station operation, including receiving sewage into the distribution plate 212, performing preliminary filtration, discharging sludge, and backflushing the arc-shaped filter plate 214. The arc-shaped filter plate 214 and the partition cavity 213 correspond one-to-one to ensure the filtration effect of each station.

[0038] Furthermore, the air extraction component 22 includes an air extraction pump 221, which is fixedly installed on the outer wall of the cylinder 211. The air inlet end of the air extraction pump 221 is connected to an air extraction pipe 222, one end of which is connected to the water filter chamber 2112. The air outlet end of the air extraction pump 221 is connected to an exhaust pipe 223, one end of which is connected to the cleaning chamber 2111.

[0039] In the above, the air extraction pipe 222 is connected to the water filtration chamber 2112. The negative pressure formed by the extracted air can accelerate the permeation of sewage through the arc-shaped filter plate 214, greatly improving the initial filtration efficiency. The exhaust pipe 223 introduces the extracted air into the cleaning chamber 2111, forming a positive airflow that blows back onto the corresponding position of the arc-shaped filter plate 214. This can effectively remove the residual sludge and impurities in the filter holes of the arc-shaped filter plate 214 at that position, reduce the risk of clogging, ensure the continuous filtration performance of the arc-shaped filter plate 214, and reduce the frequency and cost of manual cleaning and maintenance.

[0040] Furthermore, the filter press component 23 includes a conveying cylinder 232, the inlet end of which is connected to the first discharge hopper 2113. A horizontal shaft 233 is rotatably connected inside the conveying cylinder 232. The diameter of the conveying cylinder 232 gradually decreases from the middle to the outlet end. A spiral blade 237 is fixedly connected to the outer side of the horizontal shaft 233. The spiral blade 237 is adapted to the conveying cylinder 232. A drive motor 231 is fixedly installed on the bracket 1. One end of the horizontal shaft 233 passes through the conveying cylinder 232 and is fixedly connected to the rotating end of the drive motor 231. A fixing strip 234 is fixedly connected to the outer wall of the conveying cylinder 232. A sliding rod 239 is slidably connected transversely through the fixing strip 234. One end of the sliding rod 239 is fixedly connected to the outer wall of the conveying cylinder 232. A clamping plate 235 is fixedly connected to the conveying cylinder 232. The clamping plate 235 is directly opposite to the outlet end of the conveying cylinder 232 and abuts against the outlet of the conveying cylinder 232. A spring 2310 is sleeved on the outside of the sliding rod 239. One end of the spring 2310 is fixedly connected to the wall of the fixing strip 234, and the other end of the spring 2310 is fixedly connected to the wall of the clamping plate 235. A sludge discharge filter plate 236 is fixedly installed on the cylinder wall of the conveying cylinder 232. The sludge discharge filter plate 236 is adapted to the conveying cylinder 232. A water receiving hopper 238 is provided at the lower part of the conveying cylinder 232. The water receiving hopper 238 is fixedly connected to the outer wall of the conveying cylinder 232. Both the arc-shaped filter plate 214 and the sludge discharge filter plate 236 are stainless steel filter plates.

[0041] In the above, the inlet end of the conveying cylinder 232 of the filter press component 23 is connected to the first discharge hopper 2113 to ensure the stable introduction of the sludge after preliminary filtration; the gradually decreasing cylinder diameter design from the middle to the outlet end of the conveying cylinder 232, together with the spiral blades 237 on the horizontal shaft 233, forms a progressive extrusion of the sludge under the action of spiral thrust, improving the dewatering effect; the drive motor 231 provides stable power for the rotation of the horizontal shaft 233 to ensure the continuous operation of the extrusion process; the elastic clamping mechanism composed of the fixing bar 234, the slide bar 239, and the spring 2310 keeps the clamping plate 235 in contact with the conveying cylinder. The outlets of cylinder 232 abut against each other, creating reverse pressure. This pressure, combined with the spiral thrust, compacts and dewaters the sludge. The elastic properties of spring 2310 can adapt to the compaction requirements of sludge with different moisture contents, preventing excessive pressure from damaging the equipment. The sludge discharge filter plate 236 is adapted to the structural design of the conveying cylinder 232. The sludge discharge filter plate 236 filters the water released during the compaction process. The water receiving hopper 238 collects this portion of wastewater after filtration by the sludge discharge filter plate 236, facilitating subsequent centralized treatment. The stainless steel arc-shaped filter plate 214 and the sludge discharge filter plate 236 are corrosion-resistant, have high strength, and extend their service life.

[0042] Furthermore, the transmission component 24 includes a worm gear 241 and a drive vertical shaft 243. The worm gear 241 is fixedly sleeved on the outside of the horizontal shaft 233. A worm wheel 242 is fixedly sleeved on the outside of the drive vertical shaft 243. The worm wheel 242 meshes with the worm gear 241. A drive disk 244 is fixedly connected to the top of the drive vertical shaft 243. A convex arc portion 2441 and a first concave arc portion 2442 are provided on the upper outer side of the drive disk 244. An eccentric column 246 is fixedly connected to the upper part of the drive disk 244. A transmission disk 245 is fixedly connected to the bottom of the driven shaft 215. Four actuating grooves 2451 are arranged in a circumferential array on the transmission disk 245. A second concave arc portion 2452 is provided on the outer side of the transmission disk 245 between two adjacent actuating grooves 2451. The actuating grooves 2451 are adapted to the eccentric column 246. The first concave arc portion 2442 is used to avoid the transmission disk 245.

[0043] In the above, the transmission component 24 precisely converts the horizontal rotation of the horizontal shaft 233 into the vertical rotation of the vertical shaft 243 through the meshing of the worm gear 241 and the worm wheel 242. The power transmission is stable and the transmission ratio is accurate, providing reliable power guarantee for the linkage of multiple components. When the convex arc portion 2441 of the drive disc 244 is in contact with the second concave arc portion 2452 of the transmission disc 245, the driven shaft 215 can be kept stationary. With the matching of the eccentric column 246 and the actuating groove 2451, the driven shaft 215 can be rotated intermittently, ensuring the precise connection of actions such as the switching of the work position of the distribution disc 212 and the quantitative feeding of the feeding unit 3. The avoidance design of the first concave arc portion 2442 avoids interference between the drive disc 244 and the transmission disc 245, ensuring a smooth and uninterrupted transmission process. By sharing power with the filter press component 23, energy consumption is reduced.

[0044] Example 2

[0045] For further details, please refer to [link / reference]. Figures 1 to 10 Based on Embodiment 1, the feeding unit 3 includes a mixing component 31 and a waste disposal component 32; the mixing component 31 includes a mixing tank 311, which is fixedly connected to the top of the support 1, and a third discharge hopper 312 communicating with the bottom of the mixing tank 311 is fixedly connected to the bottom of the mixing tank 311. A stirring motor 313 is fixedly installed on the top of the mixing tank 311, and a stirring paddle shaft 314 is rotatably arranged inside the mixing tank 311. The top end of the stirring paddle shaft 314 is fixedly connected to the rotating end of the stirring motor 313.

[0046] In the above, the mixing component 31 of the feeding unit 3 stores the wastewater to be treated through the mixing tank 311 and uses gravity to assist in the wastewater transportation, reducing transportation energy consumption; the third discharge hopper 312 connects the mixing tank 311 with the subsequent wastewater feeding component 32, ensuring smooth wastewater flow; the stirring motor 313 drives the stirring paddle shaft 314 to rotate, which can continuously stir the wastewater in the mixing tank 311, effectively preventing sludge from settling and clumping, ensuring uniform wastewater concentration, avoiding imbalance of subsequent filtration load due to uneven material distribution, and providing a guarantee for quantitative feeding and stable separation effect.

[0047] Furthermore, the waste disposal component 32 includes an upper housing 321, which is fixedly connected to the third discharge hopper 312 and its interior is connected to the interior of the third discharge hopper 312. A waste storage tank 323 is connected to the bottom of the third discharge hopper 312, and its outer wall is fixedly connected to the support wall of the bracket 1. The outlet end of the third discharge hopper 312 is connected to the waste storage tank 323. A lower housing 322, which is connected to the outlet end of the waste storage tank 323, is fixedly connected to its interior. A driven shaft 215 is vertically rotatably connected to the upper housing 321 and the lower housing 322. An upper valve plate 324 is rotatably connected inside the upper housing 321. The upper valve plate 324 has four inlet ports 3241 arranged in a circular array. The diameter of the inlet ports 3241 is equal to the inner diameter of the third discharge hopper 312. The lower valve plate 325 is rotatably connected inside the lower housing 322. The lower valve plate 325 has four outlet ports 3251 arranged in a circular array. The diameter of the outlet ports 3251 is equal to the diameter of the outlet end of the sludge storage tank 323. The upper valve plate 324 and the lower valve plate 325 are both fixedly sleeved on the outside of the driven shaft 215. The four inlet ports 3241 and the four outlet ports 3251 are staggered. The four outlet ports 3251 are corresponding to the four partition chambers 213 one by one.

[0048] In the above, the inlet 3241 of the upper valve plate 324 has the same inner diameter as the third discharge hopper 312, and the outlet 3251 of the lower valve plate 325 has the same outlet diameter as the storage tank 323, ensuring smooth sewage transport when connected. The staggered arrangement of the four inlets 3241 and the four outlets 3251, in conjunction with the intermittent rotation of the driven shaft 215, realizes the alternation of "storage tank 323 replenishment" and "feeding to the separation chamber 213". The four outlets 3251 correspond one-to-one with the four separation chambers 213, ensuring that each separation chamber 213 receives a more equal amount of sewage, making the treatment conditions of each station more consistent and improving the stability of the separation effect.

Figures 1 to 11 Based on Embodiment 2, the water filtration unit 4 includes a filter box 411, which is fixedly connected to the wall of the support 1. The outlet end of the water receiving hopper 238 passes through the upper part of the filter box 411 and communicates with its interior. The outlet end of the second discharge hopper 2114 passes through the top of the filter box 411 and communicates with its interior. Several filter plates 412 are fixedly installed at equal intervals from top to bottom inside the filter box 411. A sewage discharge channel 414 is fixedly connected through one side of the filter plate 412. The top of the sewage discharge channel 414 is connected to the filter plate 412. The top is flush with the bottom of the drive shaft 243, which passes through all the filter plates 412 and is rotatably connected to the bottom of the inner side of the filter box 411. A scraper 413 is provided on the top of the filter plate 412, and one end of the scraper 413 is fixedly connected to the shaft wall of the drive shaft 243. A drain pipe 415 communicating with the interior is fixedly connected to the lower side of the filter box 411, and a valve is installed on the drain pipe 415. Among the filter plates 412, the filter hole diameter of the upper filter plate 412 is larger than that of the filter hole diameter of the filter plate 412 located below it.

[0051] In the above-mentioned filter box 411, several filter plates 412 are arranged at equal intervals from top to bottom. The filter holes of the upper filter plate 412 are larger than those of the lower ones, realizing graded purification from coarse filtration to fine filtration, gradually removing impurities of different particle sizes in the wastewater, and significantly improving the quality of the final effluent. The top of the sewage discharge channel 414 is flush with the top of the filter plate 412, which facilitates the smooth discharge of impurities scraped off by the scraper 413. The drive vertical shaft 243 passes through all the filter plates 412 and drives the scraper 413 to rotate, realizing automatic cleaning of each layer of filter plates 412, preventing the filter holes of the filter plates 412 from clogging, extending the service life of the filter plates 412, and reducing the amount of manual cleaning work. The drain pipe 415 is set on one side of the lower part of the filter box 411. With the help of valves, the drainage rate can be flexibly controlled to ensure that the purified water is discharged stably.

[0052] Furthermore, the vacuum pump 221, drive motor 231, and stirring motor 313 are all electrically connected to an external control switch via wires, and the vacuum pump 221, drive motor 231, and stirring motor 313 are controlled to work by the control switch.

[0053] In the above, the air pump 221, drive motor 231 and stirring motor 313 are electrically connected to an external control switch through wires to realize centralized control of each power component. The operator can start and stop the equipment through the control switch.

[0054] The working principle of the sludge-sewage separation and treatment device provided by this invention is as follows:

[0055] When the device is in operation, the sewage is transported into the mixing tank 311, the stirring motor 313 is started, and the stirring motor 313 at the top of the mixing tank 311 drives the stirring paddle shaft 314 to rotate, stirring the sewage in the tank and preventing the sludge from settling and clumping.

[0056] When the drive motor 231 is started, the rotating end of the drive motor 231 drives the horizontal shaft 233 in the filter press component 23 to rotate synchronously. The worm gear 241 fixedly sleeved on the outside of the horizontal shaft 233 meshes with the worm wheel 242 on the outside of the drive vertical shaft 243, converting the horizontal rotation of the horizontal shaft 233 into the vertical rotation of the drive vertical shaft 243. The drive disk 244 at the top of the drive vertical shaft 243 rotates together. The eccentric column 246 on the drive disk 244 periodically embeds into the actuation groove 2451 of the transmission disk 245, driving the driven shaft 215 to rotate intermittently. When the convex arc portion 2441 of the drive disk 244 is in contact with the second concave arc portion 2452 of the transmission disk 245, the driven shaft 215 remains stationary. The first concave arc portion 2442 is used to avoid the transmission disk 245, ensuring smooth transmission.

[0057] The intermittent rotation of the driven shaft 215 synchronously links the upper valve plate 324 and the lower valve plate 325 of the feeding unit 3; the upper valve plate 324 rotates with the driven shaft 215, and when the sewage inlet 3241 on it is aligned with the third discharge hopper 312, the sewage in the mixing tank 311 flows into the sewage storage tank 323 through the third discharge hopper 312, thereby replenishing the sewage storage tank 323.

[0058] Driven by the driven shaft 215, the lower valve plate 325 rotates synchronously. Since the inlet 3241 and outlet 3251 are staggered, when the outlet 3251 is aligned with the outlet end of the storage tank 323, the sewage in the storage tank 323 is quantitatively discharged into the distribution plate 212 below the lower shell 322, thereby replenishing the sewage into the distribution plate 212. Furthermore, the four outlets 3251 correspond one-to-one with the four partition chambers 213, ensuring that each partition chamber 213 receives an equal amount of sewage.

[0059] The distribution plate 212 rotates intermittently with the driven shaft 215. Each rotation of the drive plate 244 drives the eccentric column 246 to rotate synchronously. When the eccentric column 246 enters the corresponding actuation groove 2451, the eccentric column 246 actuates the transmission plate 245 to rotate once. The angle of the transmission plate 245 rotating once is ninety degrees. When the eccentric column 246 moves out of the actuation groove 2451, the convex arc portion 2441 abuts against the second concave arc portion 2452. When the distribution plate 212 stops, one of the four partition chambers 213 is located directly below the outlet end of the sludge storage tank 323 and is used to collect sludge. The other two partition chambers 213 correspond one-to-one with the cleaning chamber 2111 and the filtration chamber 2112, respectively. The last partition chamber 213 moves to be directly opposite the inlet end of the first discharge hopper 2113, so that the four partition chambers 213 correspond to different working positions, and the upper and lower ends of the partition chambers 213 are open structures.

[0060] After the wastewater enters the partition chamber 213 of the distribution plate 212, the distribution plate 212 rotates 90 degrees and rotates to the corresponding position of the filter chamber 2112.

[0061] The air pump 221 of the air extraction component 22 is started, and the air in the water filter chamber 2112 is extracted through the air extraction pipe 222, so that the water filter chamber 2112 forms a negative pressure, which accelerates the sewage in the partition chamber 213 to permeate into the water filter chamber 2112 through the arc-shaped filter plate 214, and is discharged into the filter box 411 of the water filter unit 4 through the second discharge bucket 2114 corresponding to the water filter chamber 2112.

[0062] After initial filtration, the distribution plate 212 rotates 90 degrees, and after filtration by the arc-shaped filter plate 214, the sludge remaining in the partition cavity 213 rotates with the distribution plate 212 to the corresponding position of the first discharge hopper 2113, falls into the first discharge hopper 2113 under the action of gravity, and enters the conveying cylinder 232 of the filter press component 23.

[0063] The air drawn by the air pump 221 is discharged into the cleaning chamber 2111 through the exhaust pipe 223, forming a positive airflow that blows back onto the other side of the arc-shaped filter plate 214 corresponding to the cleaning chamber 2111. At this time, the air pressure in the cleaning chamber 2111 is greater than the air pressure in the partition chamber 213, thereby blowing most of the impurities in the filter holes of the current arc-shaped filter plate 214 into the corresponding partition chamber 213; reducing the risk of sludge clogging the filter holes of the arc-shaped filter plate 214.

[0064] The sludge entering the conveying cylinder 232 from the first discharge hopper 2113 undergoes deep dewatering under the push of the spiral blades 237. When the horizontal shaft 233 rotates, the spiral blades 237 on its outer side push the sludge towards the outlet end of the conveying cylinder 232, and the diameter of the conveying cylinder 232 gradually decreases from the middle to the outlet end, forming a compression space. The clamping plate 235 set at the outlet end of the conveying cylinder 232 abuts against the outlet under the elastic force of the spring 2310, forming a reverse pressure. The sludge is compacted under the combined action of the spiral thrust and the reverse pressure. The water released during the compaction process permeates through the sludge discharge filter plate 236 on the cylinder wall of the conveying cylinder 232 to the water receiving hopper 238 at the bottom, and is introduced into the filter box 411 of the water filtration unit 4 by the water receiving hopper 238. When the pressure of the compacted sludge is greater than the elastic force of the spring 2310, the clamping plate 235 slides laterally along the fixing bar 234 through the slide rod 239, and the compacted dry sludge is discharged from the outlet of the conveying cylinder 232.

[0065] Wastewater from the second discharge hopper 2114 and the receiving hopper 238 undergoes multi-stage purification within the filter box 411: When wastewater enters the filter box 411, it flows sequentially from top to bottom through several filter plates 412, with the pore diameter of the upper filter plate 412 being larger than that of the lower filter plate 412, achieving graded filtration from coarse to fine filtration; the bottom end of the drive shaft 243 passes through all the filter plates 412 and is rotatably connected to the bottom of the inner side of the filter box 411, and when it rotates, it drives the scraper 413 on the top of the filter plate 412 to rotate synchronously, scraping the impurities trapped on the filter plate 412 to the sewage discharge channel 414 for discharge; the clear water after graded filtration collects at the bottom of the filter box 411 and is discharged through the drain pipe 415, and the valve on the drain pipe 415 can control the drainage rate.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
