Technical Field
[0001] The present invention relates to the technical field of sewage sludge separation, and specifically to an integrated device for sewage sludge separation and treatment. Background Art
[0002] With the acceleration of urbanization and the improvement of environmental protection standards, the problem of sludge separation in the sewage treatment process has become increasingly prominent. Traditional sludge treatment equipment generally adopts centrifugal separation, belt filter press or plate and frame filter press technology, which has technical bottlenecks such as easy clogging of filter nets, short cleaning cycles, high energy consumption, and low solid-liquid separation efficiency.
[0003] Especially in the dynamic filtration process, sludge particles are easily attached and deposited on the surface of the filter net, resulting in a significant attenuation of the filtration efficiency with the running time, and frequent shutdowns for manual cleaning are required, which severely restricts the treatment efficiency. Although existing technologies have tried to improve the problem of filter net clogging through high-pressure backwashing or vibration slag removal, there are defects such as a sharp increase in energy consumption, complex structure, and inability to achieve separation and self-cleaning simultaneously. In addition, traditional equipment has poor adaptability to sludge concentration fluctuations, and mechanical overload is easily caused under high solid content conditions, making it difficult to meet the requirements of continuous and intelligent operation of sewage treatment plants. Therefore, there is an urgent need to develop a sludge treatment device that integrates dynamic separation, real-time self-cleaning, and load adaptability to break through the structural limitations and efficiency bottlenecks of traditional equipment.

The protrusion includes a columnar part coaxial with the separation barrel and a filtration part uniformly connected to the outer circumference of the columnar part along the circumferential direction and radially extending, and the width of the filtration part continuously decreases from one end to the other end to form a tip structure. Drainage ports are provided on both sides of the filtration part. The drainage groove forms a water collecting groove with a circular cross-section corresponding to the columnar part, and the drainage groove forms a drainage groove with an isosceles trapezoidal cross-section corresponding to the filtration part; The filter assembly includes a filter screen installed at the drain outlet and a sealing component fixed on a base frame, the sealing component includes a first sealing portion tightly attached to the inner wall of the sump and a second sealing portion tightly attached to the bottom wall of the separation barrel. During the rotation of the separation barrel, the sealing component can intermittently and synchronously seal the bottom opening and side opening of the drain trough through its first sealing portion and the second sealing portion, thereby blocking the drainage path of the sump.
[0006] Furthermore, the separation barrel is rotatably assembled on the base frame through an upper thrust bearing and a lower thrust bearing, a limiting ring is arranged at the top of the outer wall of the separation barrel, the upper thrust bearing is arranged between the top of the limiting ring and the base frame, and the lower thrust bearing is arranged between the bottom of the separation barrel and the base frame.
[0007] Furthermore, the driving mechanism includes a driving shaft fixedly mounted on the top of the protrusion and coaxial with the separation barrel, and a driving source transmission-connected to the driving shaft, the top end of the driving shaft extends from the top of the separation barrel and is rotationally connected to the base, and the driving source is fixed on the base.
[0008] Furthermore, a fixed support shaft is coaxially arranged in the water collecting tank, the bottom end of the fixed support shaft is fixedly connected to the base frame, the top end of the fixed support shaft is rotatably connected to the top wall of the water collecting tank through a bearing seat, and the blocking member is fixed to the fixed support shaft through a connecting piece.
[0009] Furthermore, sludge storage components are evenly arranged on the outer wall of the separation barrel along the circumferential direction, and the sludge storage components are arranged corresponding to the filtering part, a sludge storage cavity extending along the height direction of the separation barrel is formed in the sludge storage component, and a strip-shaped slit is provided between the sludge storage cavity and the separation barrel, and a scraper is also arranged in the separation barrel which is close to the inside thereof, and the top end of the scraper extends from the separation barrel and is fixedly connected to the base frame.
[0010] Furthermore, the cross section of the strip-shaped slit is tapered, and the small opening end of the strip-shaped slit faces the sludge storage cavity.
[0011] Furthermore, the sludge storage component includes a columnar shell, the sludge storage cavity is formed in the columnar shell, a column with a honeycomb structure is placed in the sludge storage cavity, and an openable and closable airtight door is also arranged on the outer wall of the columnar shell.

[0013] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: 1. The present invention realizes centrifugal separation, dynamic plugging, and reverse flushing cycles through the dynamic filtration unit formed by the protruding part and the inclined filter screen, combined with the synergistic effect of the intermittent forward and reverse drive and the plugging member.

The servo motor of the present invention, combined with the variable frequency speed regulation technology and the two-stage reduction gearbox, can automatically match the rotational speed and torque according to the sludge solid content. For example, when the solid content > 20%, it operates at a high rotational speed of 1000 rpm to strengthen separation, and when the concentration is low, the frequency is reduced to 600 rpm, reducing the comprehensive energy consumption. 5. The two-way constraint system formed by the double-layer thrust bearing and the fixed support shaft of the present invention effectively disperses the centrifugal force and dynamic pressure, ensuring the stable operation of the separation barrel under high load. The modular-designed sludge storage component is equipped with an airtight door body, supporting rapid sludge cleaning and maintenance.
[0014] 6. The compression and dewatering effect of the honeycomb-structured column on sludge in the present invention can also reduce the subsequent drying treatment cost.

Detailed implementation manners
[0019] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0020] Please refer to Figures 1-6 , the present invention provides an integrated device for sewage and sludge separation treatment, including a base frame 1, a separation barrel 2 rotatably installed on the base frame 1, a filter assembly 3 installed on the separation barrel 2 (as Figure 3 shown), and a driving mechanism 4 for intermittently driving the separation barrel 2 to rotate forward and backward; Combined with Figure 3 , Figure 4 and Figure 5 shown, the center position of the bottom wall of the separation barrel 2 has a protrusion 5 protruding into the interior of the separation barrel 2 (as Figure 4 shown), and the protrusion 5 forms a concave drainage groove 51 at the bottom of the separation barrel 2 (as Figure 5 shown). The protrusion 5 includes a columnar part 52 coaxial with the separation barrel 2 and a filter part 53 uniformly connected to the outer periphery of the columnar part 52 along the circumferential direction and radially extending. The width of the filter part 53 continuously decreases from one end of the columnar part 52 to the other end to form a tip structure. Drainage ports 54 are provided on both sides of the filter part 53. The drainage groove 51 forms a water collecting tank 511 with a circular cross-section corresponding to the columnar part 52, and the drainage groove 51 forms a drainage trough 512 with an isosceles trapezoidal cross-section corresponding to the filter part 53; As shown Figure 6 in the figure, the filtering component 3 includes a filter screen 31 installed at the drain opening 54 and a plugging member 32 fixed on the base frame 1. The plugging member 32 includes a first plugging portion 321 closely attached to the inner wall of the water collecting tank 511 and a second plugging portion 322 closely attached to the bottom wall of the separation barrel 2. During the rotation of the separation barrel 2, the plugging member 32 can synchronously plug the bottom opening and the side opening of the drainage tank 512 in an intermittent manner through its first plugging portion 321 and second plugging portion 322, blocking the drainage path of the water collecting tank 511.
[0021] The device constructs an annular filtration flow field in the separation barrel 2 through the columnar portion 52 of the protruding portion 5, which can serve as the initial channel for the confluence of the sludge mixture. The filtering portion 53 of the protruding portion 5 forms a dynamic filtration unit by obliquely arranging the filter screen 31. When the driving mechanism 4 starts the rotation of the separation barrel 2, the sludge mixture quickly stratifies under the action of centrifugal force, that is, the solid particles with a larger density are enriched along the radial direction towards the side wall of the separation barrel 2, significantly reducing the sludge adhesion amount on the filter screen 31. The liquid impacts the inclined filter screen 31 on the upstream side of the protruding portion 5 along the tangential direction of rotation. The filter screen 31 is obliquely arranged, while increasing the effective filtration area, using the normal component force generated by the impact angle of the liquid flow to accelerate the penetration of the liquid, so that the liquid surges into the drainage tank 512 with an isosceles trapezoidal cross-section through the drain opening 54 and is quickly discharged through the bottom opening, improving the filtration efficiency; during this process, the filter screen 31 on the backflow side only plays an auxiliary drainage role due to the misalignment of the liquid flow direction, but its structural design foreshadows the subsequent self-cleaning stage.
[0022] With the continuous rotation of the separation barrel 2, the double plugging parts (the first plugging portion 321 and the second plugging portion 322) of the fixed plugging member 32 will continuously interfere with the drainage tank 512 as the separation barrel 2 rotates, that is, as the separation barrel 2 rotates, the plugging member 32 synchronously closes the bottom and side openings of the drainage tank 512 distributed in the circumferential direction in an intermittent rhythm, blocking the drainage path of the water collecting tank 511. When the drainage path of a certain water collecting tank 511 is blocked, the liquid is forced to flow out through the filter screen 31 on the backflow side of the water collecting tank 511. At this time, the liquid passing through the filter screen 31 on the upstream side reversely passes through the filter screen 31 on the backflow side, and a reverse strong scouring from the outside to the inside can be formed to strip the sludge attached to the surface of the filter screen 31 on the backflow side; the stripped sludge migrates along the inclined surface of the filter screen 31 towards the side wall of the separation barrel 2 under the action of centrifugal force, avoiding secondary deposition. This dynamic plugging-reverse scouring action can realize the real-time cleaning of the filter screen 31; When the driving mechanism 4 switches the rotation direction according to the preset cycle, the original active drainage side and the backflow side exchange roles, and the reverse rotation causes the filter unit that has been cleaned to turn to the frontflow side to perform the main filtration, while the original active side starts self-cleaning through the reverse liquid flow, forming a two-way alternating cleaning design. Through the precise coordination of intermittent forward and reverse drive and the blocking component 32, the device cyclically executes the "centrifugal separation-dynamic blocking-reverse flushing-path reset" process, while improving the separation efficiency, and overcoming the pain points of the traditional equipment filter screen being easy to clog and the cleaning relying on manual labor with structural innovation.
[0023] like Figure 3 As shown, in this embodiment, the separation barrel 2 is installed on the base frame 1 through a double-layer support system consisting of an upper thrust bearing 11 and a lower thrust bearing 12. A limit ring 21 is provided at the top of the outer wall of the separation barrel 2. The upper thrust bearing 11 is arranged between the top of the limit ring 21 and the base frame 1, and the lower thrust bearing 12 is arranged between the bottom of the separation barrel 2 and the base frame 1. The upper thrust bearing 11 and the lower thrust bearing 12 mainly bear the axial centrifugal force generated when the separation barrel 2 rotates and the dynamic pressure of the sludge mixture, ensuring that the separation barrel 2 rotates smoothly.
[0024] Please continue reading Figure 3 In this embodiment, the driving mechanism 4 includes a driving shaft 41 fixedly mounted on the top of the protrusion 5 and coaxial with the separation barrel 2, and a driving source 42 connected to the driving shaft 41. The top of the driving shaft 41 extends from the top of the separation barrel 2 and is connected to the base frame 1 through a bidirectional angular contact bearing. The driving source 42 is fixed to the side of the base frame 1 and is connected to the driving shaft 41 through a reduction gearbox. When starting, the output torque of the driving source 42 is amplified by the gearbox and drives the separation barrel 2 to rotate through the driving shaft 41. During the driving process, the driving source 42 implements an intermittent forward and reverse strategy (such as forward rotation for 30 seconds → stop for 2 seconds → reverse rotation for 30 seconds) to switch the direction of the separation barrel 2 through the reverse output of the gearbox.
[0025] Specifically, the driving source 42 adopts a servo motor or a variable frequency motor to achieve stepless adjustment of the speed from 0 to 1200 rpm through a frequency converter to match the separation requirements of different sludge concentrations. For example, when the sludge solid content is greater than 20%, the motor automatically increases the frequency to 1000 rpm to enhance the centrifugal force. At the same time, the secondary reduction of the gearbox (speed ratio 5:1) increases the output torque to 220 N·m to ensure separation stability under high load; under low concentration conditions, the frequency is reduced to 600 rpm to reduce the overall energy consumption.
[0026] In this embodiment, a fixed support shaft 13 is coaxially arranged in the water collecting tank 511. The bottom end of the fixed support shaft 13 is fixed to the base frame 1 by bolts or welding, and the top end of the fixed support shaft 13 is rotatably connected to the top wall of the water collecting tank 511 through a bearing seat. The plugging member 32 is fixed on the fixed support shaft 13 through a connecting member. The fixed support shaft 13 and the driving shaft 41 form an up-and-down two-way constraint, further improving the stability of the separation barrel 2 during rotation. During filtration, the separation barrel 2 rotates around the fixed support shaft 13, and the plugging member 32 remains stationary due to being fixed to the support shaft, forming a static-dynamic interface. As the separation barrel 2 rotates, the plugging member 32 sequentially blocks the bottom and side openings of the drainage groove 512 at intervals, triggering the diversion of the liquid flow.
[0027] As Figure 1 and Figure 3 shown, in this embodiment, sludge storage components 6 are uniformly arranged along the circumferential direction on the outer side wall of the separation barrel 2, and the sludge storage components 6 are correspondingly arranged with the filtering part 53. A sludge storage cavity 61 extending along the height direction of the separation barrel 2 is formed in the sludge storage component 6, and there is a strip-shaped slit 62 between the sludge storage cavity 61 and the inside of the separation barrel 2. A scraper 63 closely attached to the inside is also arranged in the separation barrel 2, and the top end of the scraper 63 extends out of the separation barrel 2 and is fixedly connected to the base frame 1. When the separation barrel 2 rotates, solid particles are enriched towards the barrel wall under the action of centrifugal force. The enriched sludge is pushed by the lateral liquid flow and enters the longitudinally extending sludge storage cavity 61 through the strip-shaped slit 62 between the storage cavity and the inner wall of the separation barrel 2. During this process, the scraper 63 fixed to the base frame 1 closely scrapes the inner wall of the separation barrel 2 synchronously, peeling off the attached sludge. The scraped sludge slides along the wall surface into the strip-shaped slit 62 under the drive of centrifugal force and enters the storage cavity for temporary storage, avoiding sludge accumulation and affecting the filtration work.
[0028] As Figure 4 shown, in this embodiment, the cross-section of the strip-shaped slit 62 is conical, and the small-mouth end of the strip-shaped slit 62 faces the sludge storage cavity 61. When the sludge enters the slit under the action of centrifugal force, due to the gradually decreasing cross-sectional area of the flow channel, the flow velocity is increased, generating a high shear force that can effectively break up sludge lumps, avoiding the blockage of the slit by sludge lumps. And the small-mouth end of the conical structure serves as a physical barrier to prevent the backflow of sludge caused by pressure fluctuations during the reverse stage.
[0029] As Figure 3 shown, in this embodiment, the sludge storage component 6 includes a columnar housing 64. The sludge storage cavity 61 is formed inside the columnar housing 64. A column with a honeycomb structure 65 is placed in the sludge storage cavity 61, and an openable and closable airtight door body 66 is also arranged on the outer wall of the columnar housing 64.
[0030] The columnar bodies of the honeycomb structure 65 in the sludge storage chamber 61 form a three-dimensional filtration interface through their porous structure. On the one hand, it increases the sludge contact area and promotes solid-liquid separation. On the other hand, through the guiding effect of the pore structure, it guides the sludge particles to be deposited orderly along the honeycomb channels, avoiding disorderly accumulation and improving the sludge dewatering efficiency. At the same time, the mechanical support of the honeycomb structure can withstand the dynamic pressure brought by the centrifugal force and prevent the columnar shell 64 from deforming.
[0031] During the sludge temporary storage stage, the openable and closable airtight door body 66 keeps the columnar shell 64 sealed. When the storage chamber reaches the capacity threshold, the door body can be opened pneumatically or mechanically, and cooperate with the external cleaning equipment to realize the automatic transfer of sludge.
[0032] As Figure 3 shown, in this embodiment, a cover body 22 with a through hole in the center is detachably installed at the top of the separation barrel 2. A liquid collecting tank 14 is arranged at the bottom of the base frame 1 corresponding to the drainage groove 51. A drain pipe 15 is arranged on one side of the liquid collecting tank 14. The central through hole of the cover body 22 allows the drive shaft 41 to penetrate or the sludge mixture feed pipe to be connected. A silica gel sealing ring is embedded at the edge of the cover body 22, and dynamic sealing is achieved by centrifugal pressing when the separation barrel 2 rotates, preventing liquid from splashing. When it is necessary to clean the inside of the separation barrel 2 or replace the filter component 3, the cover body 22 can be quickly disassembled, taking into account both the operation convenience and the sealing reliability.
[0033] The drainage groove 51 at the bottom of the separation barrel 2 throws out the filtered liquid along the drainage groove 512 with an isosceles trapezoidal cross-section under the drive of the centrifugal force. The liquid falls into the liquid collecting tank 14 below the base frame 1 through the bottom opening and is discharged from the drain pipe 15.
[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
