Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a horizontal wastewater separation device for wastewater treatment. Background Technology

[0002] Horizontal wastewater separation devices are a type of wastewater treatment equipment, typically used for solid-liquid separation or separation of substances of different densities. They are widely used in municipal wastewater and industrial wastewater treatment. Common types include horizontal screw centrifuges and horizontal sedimentation centrifuges. Due to their horizontally arranged cylindrical structure, they have the advantages of small footprint and strong operating capacity when treating large volumes of wastewater. Compared with traditional vertical sedimentation tanks, horizontal devices extend the residence time of fluids inside the equipment and improve the impurity removal rate.

[0003] Horizontal screw centrifuges generate centrifugal force through high-speed rotation, causing solid particles to settle. Then, a screw conveyor is used to separate the solids and liquids, achieving solid-liquid separation. With its high efficiency and flexibility, it has become one of the core equipment in the field of wastewater treatment.

[0004] When solids accumulate inside the drum of an existing horizontal screw centrifuge, such as large solid impurities getting stuck in the gap between the drum and the screw conveyor, the conveying efficiency is reduced or even stopped, leading to blockage inside the drum, resulting in downtime or equipment damage.

[0005] Suspended solids, colloidal or fibrous substances in the wastewater mixture adhere to the filter layer and form a dense filter cake layer, resulting in uneven liquid phase distribution inside the drum, increased torque, reduced equipment filtration efficiency, decreased treatment capacity, shortened equipment life, and increased equipment energy consumption.

[0006] Secondly, in existing horizontal screw centrifuges, after the wastewater mixture enters the device, the wastewater mixture can only be discharged after filtration, which easily causes impurities to accumulate in the feed pipe, forming a large number of short-flow zones and stagnation zones, until the feed inlet is blocked, the filtration efficiency decreases, the quality of the filtered water deteriorates, and it may even lead to overload and damage to the device.

[0007] In summary, there is an urgent need for a horizontal wastewater separation device with a flushing function and multiple layers of filtration. Summary of the Invention

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The horizontal sewage separation device for sewage treatment involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 The present invention provides a horizontal sewage separation device for sewage treatment, including a partition shell 1, a feeding and distributing device 3 movably connected to one side of the partition shell 1, a rotating drum device 2 movably connected to the inner cavity of the partition shell 1, a bladder energy storage assembly 201 fixedly connected to the outer wall of the rotating drum device 2, a conical rotating drum 202 movably connected to the inner cavity of the partition shell 1, a feeding pipe 301 movably connected to one side of the partition shell 1, and a circulation pipe 303 movably connected to the other side of the partition shell 1.

[0032] The separation and filtration of this device are carried out in the separation shell 1. The separation shell 1 serves as both a support device and a separation device, ensuring that the separated media do not mix and are collected separately. The circulation pipe 303 and the feed pipe 301 rotate around the separation shell 1 as a fulcrum. The conical drum 202 rotates inside the separation shell 1 and drives the bladder energy storage component 201 to rotate. The feed and distribution device 3 introduces wastewater and draws out unfiltered wastewater at the other end. The drum device 2 performs solid-liquid separation on the wastewater and discharges both from the two ends of the drum device 2.

[0033] Reference Figure 2 The present invention provides a horizontal sewage separation device for sewage treatment. The separation shell 1 includes a rectangular shell 101, a sludge-separating plate 102 fixedly connected to the inner wall of the rectangular shell 101, a water-separating plate 103 fixedly connected to the inner wall of the rectangular shell 101, and a clean water outlet 104 opened on one side of the rectangular shell 101.

[0034] The rectangular shell 101 and the baffle plate 102 together form a solid material discharge chamber. The rectangular shell 101 and the right side of the baffle plate 103 together form a liquid collection chamber. The liquid is discharged and collected through the clean water outlet 104. The solid and liquid media are separated by the chamber formed by the baffle plate 102, the baffle plate 103 and the rectangular shell 101.

[0035] Reference Figure 3 This invention provides a horizontal sewage separation device for sewage treatment. One end of a conical drum 202 is fixedly connected to a sewage discharge ring 204, and a sewage discharge port 203 is provided on the outer wall of the sewage discharge ring 204. The other end of the conical drum 202 is fixedly connected to a main drum shell 205. A drain outlet 207 is fixedly connected to the outer wall of the main drum shell 205. One end of the drain outlet 207 is fixedly connected to a bladder energy storage component 201. A U-shaped input pipe 208 is fixedly connected to one side of the bladder energy storage component 201. One end of the U-shaped input pipe 208 is fixedly connected to one side of the main drum shell 205. A through hole 206 is provided on one side of the main drum shell 205. A total drain outlet 211 is provided on one side of the main drum shell 205. The outer wall of the bladder energy storage component 201 is fixedly connected to the outer wall of the main drum shell 205.

[0036] The connection end between the conical drum 202 and the drain ring 204 is the solid material discharge point. The drain ring 204 uses centrifugal force to throw the solid discharged from the conical drum 202 out through the drain port 203. The main drain port 211 and the U-shaped input pipe 208 collect the liquid discharged from one side of the main drum shell 205. The main drain port 211 discharges the liquid, and the U-shaped input pipe 208 transports the liquid to the bladder energy storage component 201 and the drain port 207. Then, it is discharged into the main drum shell 205 through the drain port 207 to achieve the rinsing function. The drain port 207 discharges the liquid into the cavity formed by the water baffle plate 103 and the rectangular shell 101, and then discharges and collects it through the clean water outlet 104. The through hole 206 is a reserved hole for the feeding and distributing device 3 to penetrate the drum device 2.

[0037] Reference Figure 4 The present invention provides a horizontal sewage separation device for sewage treatment. A backflush hole 210 is provided on one side of the main shell 205 of the drum, and an input pipe hole 209 is provided on the other side of the main shell 205 of the drum. The input pipe hole 209 is a connection hole for the U-shaped input pipe 208 on the main shell 205 of the drum, and the backflush hole 210 provides a position for the installation of the one-way nozzle 2071.

[0038] Reference Figure 5 This invention provides a horizontal sewage separation device for sewage treatment. An energy storage shell 2011 is fixedly connected to one side of a drain outlet 207. A one-way nozzle 2071 is fixedly connected to the side wall of the drain outlet 207. An air vent 2017 is provided on one side of the energy storage shell 2011. A contraction bladder 2012 is fixedly connected to one side of the air vent 2017 and is movably installed inside the energy storage shell 2011. A pressure chamber 2013 is fixedly connected to one side of the energy storage shell 2011. The inner wall of the pressure chamber 2013 has... There is a sliding groove 2014, and a sliding plate 2016 is slidably connected inside the sliding groove 2014. A compression spring 2015 is fixedly connected to the inner wall of the air pressure chamber 2013. One side of the compression spring 2015 is fixedly connected to the sliding plate 2016. An energy storage input hole 2019 is opened on the side wall of the energy storage shell 2011. A U-shaped input pipe 208 is fixedly connected to one end of the energy storage input hole 2019. An energy storage output hole 2018 is opened on the side wall of the energy storage shell 2011. A drain outlet 207 is fixedly connected to one side of the energy storage output hole 2018.

[0039] The one-way nozzle 2071 is a prior art nozzle. When the external pressure is less than the internal pressure of the drain outlet 207, it uses water pressure to spray a high-speed water flow to achieve the cleaning function. The one-way function also prevents sewage in the main shell 205 of the drum from entering the drain outlet 207. The contraction bladder 2012 achieves the contraction function through the pressure in the energy storage shell 2011. The air pressure chamber 2013 cooperates with the contraction bladder 2012 to squeeze air into the air pressure chamber 2013 or release it into the contraction bladder 2012 through the air hole 2017. The sliding plate 2016 slides along the slide groove 2014 to expand and shrink the space in the air pressure chamber 2013. The contraction spring 2015 resets the sliding plate 2016. The liquid flowing in through the U-shaped input pipe 208 enters the energy storage shell 2011 through the energy storage input hole 2019, squeezes the contraction bladder 2012, and then enters the drain outlet 207 through the energy storage output hole 2018.

[0040] Reference Figure 6 The present invention provides a horizontal sewage separation device for sewage treatment, wherein a spiral pusher 302 is fixedly connected to the outer wall of the feed pipe 301, a circulation pipe 303 is fixedly connected to the inside of the spiral pusher 302, and a material distribution screen ring 304 is fixedly connected to the inside of the spiral pusher 302.

[0041] The feed pipe 301 transports the wastewater mixture to the dividing screen ring 304, which filters out large particles and discharges fine particles and liquid. The screw conveyor 302 separates the solid and liquid using centrifugal force and pushes them to the solid and liquid outlets respectively. The large particles and unfiltered mixture in the dividing screen ring 304 are circulated back to the feed pipe 301 through the circulation pipe 303 for further filtration.

[0042] Reference Figure 7 The present invention provides a horizontal sewage separation device for sewage treatment. A material distribution screen ring 304 is fixedly connected to one side of the feed pipe 301, a connecting plate 305 is fixedly connected to one side of the material distribution screen ring 304, a circulation pipe 303 is fixedly connected to one side of the connecting plate 305, a circulation hole 306 is opened in the middle of the connecting plate 305, and a screen hole 307 is opened on the side wall of the material distribution screen ring 304.

[0043] The connecting plate 305 and the circulation hole 306 intercept part of the sewage mixture, which helps to improve the filtration efficiency, and uses the retained large particles of impurities to scrape off the dirt clogging the screen hole 307.

[0044] Reference Figure 8This invention provides a horizontal sewage separation device for sewage treatment. A screw feeder 302 is movably installed in the inner cavity of the main drum shell 205 and the conical drum 202. A feed pipe 301 is fixedly connected inside the screw feeder 302. A distribution screen ring 304 is fixedly connected to one side of the feed pipe 301. The side wall of the distribution screen ring 304 has a screen hole 307. A discharge ring 204 is fixedly connected to one side of the conical drum 202. A circulation pipe 303 is fixedly connected to one side of the distribution screen ring 304. The outer walls of the circulation pipe 303 and the feed pipe 301 are movably connected to the inner walls of the main drum shell 205 and the discharge ring 204.

[0045] There is a certain gap between the screw feeder 302 and the main shell of the drum 205. This gap is larger than the diameter of the screen hole 307, which reduces the wear device caused by impurities staying between the screw feeder 302 and the main shell of the drum 205. The feed pipe 301 and the circulation pipe 303 rotate on the inner wall of the drain ring 204 and the main shell of the drum 205, and there are sealing measures at the connection.

[0046] The working principle of this invention: The wastewater mixture enters the device through the feed pipe 301. At this time, the drum device 2 and the feed distribution device 3 rotate under the drive of an external motor, with a certain speed difference. The wastewater mixture retains large particles of impurities at the distribution screen ring 304, while fine particles and liquid enter the inner cavity formed by the drum device 2 and the feed distribution device 3. The screw pusher 302 rotates at the same speed as the feed pipe 301. The medium discharged from the distribution screen ring 304 is used to precipitate solids on the main shell of the drum 205 and the conical drum 202 by the centrifugal force generated by the high-speed rotation of the screw pusher 302. The screw pusher 302 rotates in the same direction as the main shell of the drum 205 and the conical drum 202, thereby moving the solids to the discharge ring 204. Then, the solids are discharged into the cavity formed by the rectangular shell 101 and the baffle plate 102 through the discharge port 203. There is no bottom plate below this cavity, so solid matter can be collected below the cavity.

[0047] Unfiltered wastewater mixture in the distribution screen ring 304 is discharged into the circulation pipe 303 through the connecting plate 305. The circulation pipe 303 connects the external pipeline back to the feed pipe 301, thus achieving multiple filtrations.

[0048] The screw feeder 302 pushes the separated liquid to the U-shaped input pipe 208 and the main drain outlet 211. Due to the rotation, part of the liquid enters the U-shaped input pipe 208, and most of the liquid is discharged through the main drain outlet 211 into the cavity formed by the rectangular shell 101 and the water baffle 103, and then discharged and collected through the clean water outlet 104.

[0049] Liquid entering the U-shaped input pipe 208 flows into the energy storage shell 2011 and fills the energy storage shell 2011, the drain outlet 207, and the U-shaped input pipe 208, compressing the contraction bladder 2012. The air in the contraction bladder 2012 is compressed into the air pressure chamber 2013, pushing the sliding plate 2016 inward and compressing the contraction spring 2015. When the air pressure in the drum device 2 is greater than or equal to the internal pressure of the bladder energy storage assembly 201, the internal pressure of the bladder energy storage assembly 201 is maintained.

[0050] When excessive impurities inside the distribution screen ring 304 form mud cakes that clog the screen holes 307, the filtration rate decreases. While the material in the rotating drum device 2 is still being discharged outwards, the pressure in the rotating drum device 2 drops to the threshold value, the one-way nozzle 2071 opens, and the contraction spring 2015, sensing the decrease in pressure in the energy storage shell 2011, rapidly pushes compressed air into the contraction bladder 2012, causing the contraction bladder 2012 to expand and squeeze the liquid in the energy storage shell 2011 to be discharged through the drain outlet 207 and the one-way nozzle 2071. The high-speed water flow, due to the position of the one-way nozzle 2071 and the backflush hole 210 corresponding to the axial position of the distribution screen ring 304, washes the distribution screen ring 304, washing away the mud cake formed inside the screen hole 307 and the distribution screen ring 304. Due to the speed difference between the drum device 2 and the feeding and distributing device 3, the high-speed water flow does not wash the distribution screen ring 304 at a fixed position. When the pressure in the drum device 2 is restored, the U-shaped input pipe 208 begins to deliver liquid into the energy storage shell 2011, and the cycle repeats.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
