Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically a sludge processor for treating sludge in black and odorous water bodies in rural areas. Background Technology

[0002] Sludge refers to a mixture containing solid particles produced during wastewater treatment using physical, chemical, physicochemical, and biological methods. It is a viscous substance between liquid and solid, primarily consisting of organic fragments, bacterial cells, inorganic particles, and colloids, forming an extremely complex heterogeneous body. Sludge typically contains a large amount of water, with a moisture content usually between 50% and 99%. It has a high organic content, is prone to decay and odor, and its fine particles and low specific gravity give it a colloidal liquid state, allowing it to be transported by pumps but making solid-liquid separation difficult through sedimentation. Due to differences in sludge sources and water treatment methods, the properties of sludge vary, resulting in many types and complex classifications. Corresponding treatment methods are diverse, with the specific choice depending on factors such as the sludge's properties, quantity, treatment costs, and final use. Common sludge treatment methods include dewatering, composting, incineration, landfill, and soil amendment.

[0003] Sludge from polluted and odorous water bodies in rural areas typically has a high water content. This high water content makes the sludge more viscous, difficult to handle and transport, thus complicating the dewatering process and increasing energy consumption, while also increasing the difficulty of subsequent treatment. Sludge often contains tiny particles that are difficult to remove using traditional dewatering methods, causing clogging and damage to filtration and dewatering equipment. Furthermore, environmental conditions such as temperature and humidity also affect dewatering efficiency; dewatering becomes more difficult in cold or humid environments. Therefore, we propose a sludge processor for treating sludge from polluted and odorous water bodies in rural areas. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sludge processor for treating sludge in black and odorous water bodies in rural areas, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a sludge processor for treating sludge in black and odorous water bodies in rural areas, comprising a sludge tank, a feeding hopper fixedly installed above the sludge tank, a pretreatment box for anaerobic digestion of sludge provided at the upper end of the feeding hopper, a squeezing column movably fitted inside the sludge tank, a first servo motor fixedly installed at the rear side of the sludge tank, a first telescopic column fixedly installed on the left side of the sludge tank, a squeezing plate fixedly connected to the right side of the output shaft of the first telescopic column, a distribution plate fixedly installed inside the sludge tank, a discharge plate fixedly installed on the left side of the distribution plate, and a feeding plate movably connected to the right side of the distribution plate;

[0006] Push scraper ring assemblies are provided on the front and rear sides of the sludge tank and around the periphery of the extrusion column. The scraper ring assembly includes a first mounting sliding ring located outside the extrusion column and connected to the inner wall of the sludge tank, a second mounting sliding ring distributed opposite to the first mounting sliding ring, a plurality of connecting bent rods circumferentially hinged to the outer wall of the second mounting sliding ring, a plurality of pushing connecting rods located between each of the connecting bent rods and the side wall of the first mounting sliding ring, and a first hydraulic cylinder located between the first mounting sliding ring and the inner wall of the sludge tank. Each connecting bent rod has an arc-shaped scraper on the side away from the pushing connecting rod, and each of the arc-shaped scrapers forms a circular opening structure.

[0007] The inner cavity of the sludge box is fixedly fitted with a feeding conveyor belt, and a second servo motor is fixedly installed at the rear of the sludge box.

[0008] Optionally, a support plate is fixedly installed on the top wall of the inner cavity of the sludge tank, a support spring is fixedly connected to the left side of the support plate, a discharge shovel is fixedly connected to the left side of the support spring, a second telescopic column is fixedly installed inside the sludge tank, a first connecting column is movably connected above the output shaft of the second telescopic column, a first fan sleeve is fixedly fitted inside the top and bottom walls of the sludge tank, a flow-guiding fan is fixedly fitted inside the first fan sleeve, a discharge plate is fixedly connected to the right wall of the inner cavity of the sludge tank, and an electric heating plate is fixedly fitted inside the sludge tank.

[0009] Note: Positioning the upper left side of the feeding conveyor belt below the feed plate facilitates the use of the device, allows for further dewatering of the sludge, and facilitates sludge drying. Combined with the extrusion column and extrusion plate, it can complete sludge treatment, allowing the sludge to be directly discharged to the outside.

[0010] Optionally, two support blocks are fixedly installed on the top of the sludge tank, and support columns are fixedly fitted on the inner sides of the two support blocks. Two condensing plates are movably connected to the outer side of the discharge shovel. A second fan sleeve is fixedly installed on the top of the condensing plates. A cooling fan is fixedly fitted inside the cavity of the second fan sleeve. A third telescopic column is fixedly installed on the front and rear sides of the sludge tank, and a second connecting column is connected above the output shaft of the third telescopic column.

[0011] Explanation: A condensing plate is installed above the sludge tank, and a second fan sleeve is installed above the condensing plate to facilitate the condensation of moisture discharged from the inside of the sludge tank. This prevents the surrounding air humidity from increasing during the operation of the device, which could affect the normal life of residents. During use, the cooperation of the third telescopic column and the second connecting column makes it easy to control the tilt angle of the condensing plate, and to control the drainage speed according to the feed rate.

[0012] Optionally, the sludge box has an inlet at the top, the inlet is located below the feed hopper, the inlet is located above the left side of the extrusion column, the top surface of the second connecting column is in contact with the bottom surface of the condensing plate, the outer side of the condensing plate is located below the inner side, the second fan sleeve and the condensing plate are parallel to each other, and the condensing plate is located above the first fan sleeve.

[0013] Note: The feed inlet is positioned to facilitate the feeding of sludge to the upper left of the extrusion column during operation, making it easier to transport the sludge downwards. This simplifies the operation of the device and improves its practicality.

[0014] Optionally, the extrusion plate is located to the left of the extrusion column, and the rear of the extrusion column is fixedly connected to the output shaft of the first servo motor. The height of the extrusion plate is greater than the diameter of the extrusion column.

[0015] Explanation: The extrusion plate is designed to facilitate the initial dewatering of sludge in conjunction with the extrusion column. At the same time, the first servo motor controls the rotation of the extrusion column, which facilitates dewatering while assisting in the transport of sludge into the sludge tank.

[0016] Optionally, the left side of the feeding shovel and the right side of the extrusion column are attached together, and the top surface of the first connecting column and the bottom surface of the feeding plate are attached together.

[0017] Explanation: The setting of the first connecting column and the cooperation of the second telescopic column facilitate the control of the tilt angle of the feed plate, facilitate the control of the feeding speed using the feed plate, and facilitate the use of the device. The setting of the feeding shovel plays the role of scraping off the silt outside the squeezing column.

[0018] Optionally, the heating plate is located above the feeding conveyor belt, and the bottom surface of the heating plate and the top surface of the feeding conveyor belt are parallel to each other vertically.

[0019] Explanation: The electric heating plate is designed to dry the sludge, facilitating the complete removal of moisture from the sludge, thus simplifying the use of the device and improving its practicality. At the same time, the feeding conveyor belt provides continuous feeding, enabling continuous operation and effectively improving work efficiency.

[0020] Optionally, the upper first fan sleeve is located above the heating plate, and the lower first fan sleeve is located below the feeding conveyor belt. The discharge plate has an exhaust hole that runs vertically through it.

[0021] Explanation: By utilizing the first fan sleeve and cooperating with the internal airflow fan, it is convenient to control the rise of water vapor inside the sludge tank. At the same time, the discharge plate has an exhaust hole inside to facilitate the discharge of moisture through airflow.

[0022] Optionally, the discharge plate is inclined toward the discharge port of the sludge tank, and a U-shaped mounting frame is arranged parallel to it at the bottom of the discharge plate inside the sludge tank. The vertical section of the U-shaped mounting frame is connected to the left and right ends of the discharge plate through a vibration rod. An anti-clogging cleaning plate is slidably connected inside the U-shaped mounting frame and distributed parallel to the discharge plate. The anti-clogging cleaning plate is provided with multiple piercing vertical rods, and the multiple piercing vertical rods correspond one-to-one with the vent holes on the discharge plate. A second hydraulic cylinder is provided between the bottom end of the anti-clogging cleaning plate and the U-shaped mounting frame.

[0023] Explanation: The function of the discharge plate is to discharge dry sludge. To facilitate the discharge of moisture through airflow, the vent holes on the discharge plate must always be kept unobstructed. When the vent holes become blocked, the vibrating rod is activated to vibrate the discharge plate. At the same time, the second hydraulic cylinder is activated. Through the repeated compression and extension of the second hydraulic cylinder, the piercing rod pierces back and forth through the vent holes, thereby cleaning the discharge plate. The structure is simple, requires no human intervention, has a high degree of automation, ensures smooth discharge of moisture, avoids damage to other electrical equipment in the sludge tank, and extends the service life of the device.

[0024] Optionally, the diameter of the puncture rod is smaller than the diameter of the vent hole, and the outer wall of the puncture rod is provided with cleaning bristles, and the bottom two sides of the anti-clogging cleaning plate are provided with reinforcing support rods.

[0025] Explanation: By limiting the dimensional relationship between the piercing vertical rod and the vent hole, it is ensured that the piercing vertical rod can pass smoothly through the vent hole. At the same time, the cleaning effect is improved by setting cleaning bristles, and the overall mechanical strength of the discharge plate and the anti-clogging cleaning plate is increased by setting reinforcing support rods on both sides of the bottom end of the anti-clogging cleaning plate.

[0026] The present invention has the following beneficial effects:

[0027] This sludge processor for treating sludge in black and odorous water bodies in rural areas has a feeding hopper above the sludge tank. A first telescopic column is fixedly installed on the left side of the sludge tank, and an extrusion plate is fixedly connected to the right side of the output shaft of the first telescopic column. The extrusion column and the first servo motor work together to facilitate the initial dewatering of the sludge. At the same time, the push scraper ring assembly inside the sludge tank and relatively distributed at both ends of the extrusion column initially scrapes the initially dewatered sludge on the outer wall of the extrusion column in the horizontal direction. Then, the sludge on the outer wall of the extrusion column is rotated and scraped by the feeding shovel, which greatly improves the cleaning efficiency of the sludge. No manual cleaning is required, the degree of automation is high, and the setting of the separation plate facilitates the initial separation of sludge and sewage.

A second servo motor is fixedly installed on the left side of the feeding conveyor belt, and a discharge plate is fixedly installed on the right side of the inner cavity of the sludge tank. Electric heating plates are fixedly installed in the upper and lower inner cavities of the sludge tank, and a diversion fan is fixedly installed inside the electric heating plates. This facilitates the thorough dewatering of the sludge using the feeding conveyor belt and makes the device easy to use.

[0029] 3. The sludge processor for treating sludge in black and odorous water bodies in rural areas has a support column installed on the top of the sludge tank via a support block. The support column is externally connected to a condensing plate. A second fan sleeve is installed above the condensing plate, and a cooling fan is fixedly installed inside the second fan sleeve. At the same time, a third telescopic column is fixedly connected to the left and right sides of the sludge tank, and the top of the third telescopic column is connected to a second connecting column, so that the condensing plate can be used to complete the condensation of water droplets.

[0030] 4. When the vent hole is blocked, open the vibrating rod to make the discharge plate vibrate. At the same time, open the second hydraulic cylinder. Through the repeated compression and extension of the second hydraulic cylinder, the piercing rod pierces the vent hole back and forth, thereby cleaning the discharge plate. The structure is simple, requires no human intervention, has a high degree of automation, ensures smooth discharge of moisture, avoids moisture damage to other electrical equipment in the sludge tank, and extends the service life of the device.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Please see Figures 1 to 6This invention provides a technical solution: a sludge processor for treating sludge in black and odorous water bodies in rural areas, including a sludge tank 1, a feed hopper 2 fixedly installed on the top of the sludge tank 1, a pretreatment box for anaerobic digestion of sludge at the upper end of the feed hopper 2, a squeezing column 3 movably fitted inside the sludge tank 1, and a feed inlet located below the feed hopper 2 and above the left side of the squeezing column 3. This inlet placement facilitates the feeding of sludge to the upper left position of the squeezing column 3, allowing for downward transport of the sludge and improving the device's usability. A first servo motor 6 is fixedly installed on the rear side of the sludge tank 1. A first telescopic column 4 is fixedly installed on the left side of the sludge box 1. A pressing plate 5 is fixedly connected to the right side of the output shaft of the first telescopic column 4. The pressing plate 5 is located on the left side of the pressing column 3. The back of the pressing column 3 is fixedly connected to the output shaft of the first servo motor 6. The height of the pressing plate 5 is greater than the diameter of the pressing column 3. The setting of the pressing plate 5 facilitates the initial dewatering of sludge in conjunction with the pressing column 3. At the same time, the first servo motor 6 controls the rotation of the pressing column 3, which facilitates dewatering while assisting in the transport of sludge into the sludge box 1. The left side of the distribution plate 7 and the axis of the pressing column 3 are located on the same vertical plane. The setting of the distribution plate 7 facilitates the separation and transport of sewage and sludge in use. The distribution plate 7 is fixedly installed inside the sludge box 1. A discharge plate 8 is fixedly installed on the left side of the distribution plate 7. A feed plate 12 is movably connected to the right side of the distribution plate 7.

[0043] like Figure 7 , 8 As shown, a push scraper ring assembly 30 is provided on the front and rear sides of the sludge tank 1 and located around the extrusion column 3. The scraper ring assembly 30 includes a first mounting sliding ring 300 located outside the extrusion column 3 and connected to the inner wall of the sludge tank 1, a second mounting sliding ring 301 distributed opposite to the first mounting sliding ring 300, two connecting rods 302 circumferentially hinged to the outer wall of the second mounting sliding ring 301, two push connecting rods 303 located between each connecting rod 302 and the side wall of the first mounting sliding ring 300, and a first hydraulic cylinder 304 located between the first mounting sliding ring 300 and the inner wall of the sludge tank 1. Each connecting rod 302 has an arc-shaped scraper 305 on the side away from the push connecting rod 303. Each arc-shaped scraper 305 forms a circular opening structure. An electric telescopic rod 306 is provided between the bottom end of each push connecting rod 303 and the first mounting sliding ring 300.

[0044] A support plate 9 is fixedly installed on the top wall of the inner cavity of the sludge tank 1. A support spring 10 is fixedly connected to the left side of the support plate 9, and a feeding shovel 11 is fixedly connected to the left side of the support spring 10. The left side of the feeding shovel 11 is attached to the right side of the extrusion column 3. The top surface of the first connecting column 14 is attached to the bottom surface of the feed plate 12. The arrangement of the first connecting column 14 and the cooperation of the second telescopic column 13 facilitates the control of the tilt angle of the feed plate 12 and the control of the feeding speed using the feed plate 12, thus facilitating the use of the device. The feeding shovel 11 serves to scrape off the sludge outside the extrusion column 3. By utilizing the cooperation of the extrusion column 3 and the extrusion plate 5, the sludge undergoes preliminary dewatering. The squeezed-out water is discharged from the left side of the sludge tank 1 through the discharge plate 8, while the sludge still contains some water. Water causes the sludge to adhere to each other and to the outside of the extrusion column 3, facilitating its fall onto the feed plate 12. A second telescopic column 13 is fixedly installed inside the sludge tank 1. A first connecting column 14 is movably connected above the output shaft of the second telescopic column 13. During rotation, the support plate 9 supports the discharge shovel 11 via the support spring 10. The discharge shovel 11 shovels the sludge from the outside of the extrusion column 3, allowing it to fall onto the feed plate 12. The lifting and lowering of the output shaft of the second telescopic column 13 is controlled according to the feeding speed, allowing the second telescopic column 13 to control the lifting and lowering of the first connecting column 14, thus controlling the tilt angle of the feed plate 12 and consequently the feeding speed. The sludge then falls onto the feeding conveyor belt 15, facilitating the use of the device.

[0045] The inner cavity of the sludge tank 1 is fixedly fitted with a feeding conveyor belt 15. An electric heating plate 17 is located above the feeding conveyor belt 15. The bottom surface of the electric heating plate 17 (which is existing technology and will not be described in detail here) and the top surface of the feeding conveyor belt 15 are parallel to each other. The electric heating plate 17 serves to dry the sludge, facilitating the complete removal of moisture from the sludge, simplifying the use of the device, and improving its practicality. Simultaneously, the feeding conveyor belt 15 provides continuous feeding, facilitating continuous operation and effectively improving work efficiency. A second servo motor 16 is fixedly installed at the rear of the sludge tank 1. First fan sleeves are fixedly fitted inside the top and bottom walls of the sludge tank 1. The upper first fan sleeve is located above the electric heating plate 17, and the lower first fan sleeve is located below the feeding conveyor belt 15. The discharge plate 18 has a through-hole for exhaust. With the first fan sleeve and the internal guide fan 20, the rise of water vapor in the sludge tank 1 can be easily controlled. The exhaust holes in the discharge plate 18 facilitate the discharge of moisture by airflow. The guide fan 20 is fixedly installed inside the first fan sleeve. The discharge plate 18 is fixedly connected to the right wall of the sludge tank 1. The heating plate 17 is fixedly installed inside the sludge tank 1, so that the upper left side of the feeding conveyor belt 15 is below the feed plate 12, which facilitates the use of the device and the further dewatering and drying of the sludge. With the extrusion column 3 and extrusion plate 5, the sludge can be processed and discharged directly to the outside.

[0046] Two support blocks 21 are fixedly installed on the top of the sludge tank 1. Support columns 22 are fixedly fitted inside the two support blocks 21. Two condensing plates 23 (the condensing plates 23 are existing technology and will not be described in detail here) are movably connected to the outer side of the discharge shovel 11. The top surface of the second connecting column 27 is in contact with the bottom surface of the condensing plate 23, with the outer side of the condensing plate 23 located below the inner side. Utilizing the third telescopic column 26 and the second connecting column 27, the tilt angle of the condensing plate 23 can be easily controlled during use, facilitating the control of the drainage speed based on the feed rate. A second fan sleeve 24 is fixedly installed above the condensing plate 23, and the second fan sleeve 24 is parallel to the condensing plate 23. The condenser plate 23 is located above the first fan sleeve. The second fan sleeve 24 is set above the condenser plate 23 to facilitate rapid cooling of the surface of the condenser plate 23, so that the high-temperature water vapor rising in the inner cavity of the sludge tank 1 can be quickly condensed, which facilitates the separation of sludge and water. The inner cavity of the second fan sleeve 24 is fixedly fitted with a cooling fan 25. The front and rear sides of the sludge tank 1 are fixedly installed with a third telescopic column 26. The output shaft of the third telescopic column 26 is connected to a second connecting column 27. The condenser plate 23 is set above the sludge tank 1. At the same time, the second fan sleeve 24 is set above the condenser plate 23 to facilitate the condensation of the moisture discharged from the inside of the sludge tank 1, so as to avoid the increase of ambient air humidity during the operation of the device and affect the normal life of residents.

[0047] like Figure 9 As shown, the discharge plate 2 18 is inclined towards the discharge port of the sludge tank 1. A U-shaped mounting bracket 180 is installed parallel to the bottom of the discharge plate 2 18 inside the sludge tank 1. The vertical section of the U-shaped mounting bracket 180 is connected to the left and right ends of the discharge plate 2 18 via vibrating rods 181. Anti-clogging cleaning plates 182, parallel to the discharge plate 2 18, are slidably connected inside the U-shaped mounting bracket 180. The anti-clogging cleaning plates 182 have 20 piercing vertical rods 183, each corresponding to a vent hole on the discharge plate 2 18. A second hydraulic cylinder 184 is located between the bottom of the anti-clogging cleaning plate 182 and the U-shaped mounting bracket 180. The function of discharge plate 18 is to discharge dry sludge. In order to facilitate the discharge of moisture through airflow, the vent holes on discharge plate 18 must always be kept unobstructed. When the vent holes are blocked, the vibrating rod 181 is turned on to make discharge plate 18 vibrate. At the same time, the second hydraulic cylinder 184 is turned on. Through the repeated compression and extension of the second hydraulic cylinder 184, the piercing rod 183 is pierced back and forth through the vent holes, thereby achieving the purpose of cleaning discharge plate 18. The structure is simple, requires no human intervention, has a high degree of automation, ensures smooth discharge of moisture, avoids moisture damage to other electrical equipment in sludge tank 1, and extends the service life of the device.

[0048] Optionally, the diameter of the piercing vertical rod 183 is 3mm smaller than the diameter of the vent hole, and the outer wall of the piercing vertical rod 183 is provided with cleaning bristles 185. The bottom sides of the anti-clogging cleaning plate 182 are provided with reinforcing support rods 186. By limiting the size relationship between the piercing vertical rod 183 and the vent hole, it is ensured that the piercing vertical rod 183 can pass through the vent hole smoothly. At the same time, the cleaning effect is improved by setting the cleaning bristles 185, and the overall mechanical strength of the discharge plate 18 and the anti-clogging cleaning plate 182 is increased by setting the reinforcing support rods 186 on both sides of the bottom of the anti-clogging cleaning plate 182.

[0049] In summary, this sludge processor for treating sludge in rural black and odorous water bodies first performs anaerobic digestion on the sludge in a pretreatment tank. Then, the sludge is thrown downwards from above the feed hopper 2, allowing it to enter the inner cavity of the feed hopper 2 and fall into the sludge tank 1. Simultaneously, the first servo motor 6 is activated, controlling the output shaft of the first telescopic column 4 to extend according to the feeding speed. This causes the first telescopic column 4 to push the extrusion plate 5 to the right, moving the extrusion plate 5 to a suitable position. The cooperation of the extrusion column 3 and the extrusion plate 5 performs preliminary dewatering of the sludge. The squeezed-out water is discharged through the discharge plate 8. The sludge is discharged from the left side of the sludge tank 1. Since the sludge still contains some water, it adheres to itself and to the outside of the extrusion column 3. During rotation, the tilt angle of the connecting bent rod 302 is adjusted via the electric telescopic rod 306 until each arc-shaped scraper 305 adheres to the outer wall of the extrusion column 3. Then, the two relatively distributed first hydraulic cylinders 304 are activated. Through the extension action of the first hydraulic cylinders 304, the two relatively distributed second mounting sliding rings 301 are brought closer together, and the arc-shaped scrapers 305 initially scrape the sludge on the outer wall of the extrusion column 3 horizontally. Then… The support plate 9 supports the unloading shovel 11 via the support spring 10. The unloading shovel 11 scrapes off the sludge from the outside of the extrusion column 3, causing the sludge to fall above the feeding plate 12. Based on the feeding speed, the lifting and lowering of the output shaft of the second telescopic column 13 is controlled, allowing the second telescopic column 13 to control the lifting and lowering of the first connecting column 14, thus controlling the tilt angle of the feeding plate 12 and consequently the feeding speed of the feeding plate 12. The sludge then falls above the feeding conveyor belt 15, and the output shaft of the second servo motor 16 is started, causing the feeding conveyor belt 15 to transport the sludge to the right. Simultaneously, the heating plate 17 is activated, using the heating plate 17 to... The sludge above the feeding conveyor belt 15 is heated to rapidly evaporate the moisture inside the sludge, causing the dried sludge to move to the right and be transported to the right by the discharge plate 18. The discharge plate 18 discharges the sludge. At the same time, the two first fan sleeves' internal drainage fans 20 are activated to drain the moisture inside the sludge tank 1, causing the moisture inside the sludge tank 1 to be transported upwards. Then, the moisture is sent to the top of the sludge tank 1, where the cooling fan 25 blows air onto the surface of the condensing plate 23, keeping the surface of the condensing plate 23 at a low temperature, causing the water vapor to condense into water droplets.
