Description

Technical Field

[0001] This invention relates to the field of sludge separation technology, and in particular to a high-efficiency heavy sludge separation system. Background Technology

[0002] In the field of wastewater treatment and resource utilization, the efficient separation of heavy sludge (such as aerobic granular sludge and high-density bioflocs) is a key step in achieving sludge reduction, harmlessness, and resource recovery. Due to their high density, specific particle size distribution, and concentration characteristics, the separation efficiency of this type of heavy sludge directly affects the stability of subsequent treatment processes and the efficiency of resource recovery.

[0003] However, existing heavy sludge separation equipment has many limitations in practical applications, mainly in the following aspects:

[0004] 1. Traditional equipment mostly adopts a single-stage separation structure, which cannot purify heavy sludge step by step. This results in low purity and recovery rate of heavy sludge products, and serious contamination of light flocs and other impurities, making it difficult to meet the purity requirements for subsequent resource utilization.

[0005] 2. The physical properties (density, particle size distribution, concentration) of heavy sludge vary significantly depending on the source of wastewater and the treatment process. However, the core parameters of existing equipment (such as cone angle, height ratio of pre-separation zone to main separation zone, etc.) are fixed and cannot be dynamically adjusted according to the properties of sludge, resulting in a significant decrease in separation performance under different operating conditions.

[0006] 3. Existing equipment is mostly single-unit devices with fixed specifications and fixed processing capacity. If it is necessary to increase the processing capacity, the entire equipment needs to be replaced, which is not only costly, but also cannot achieve linear expansion and is difficult to adapt to the dynamic changes in the scale of sewage treatment. Summary of the Invention

[0007] To address the problems mentioned in the background section, this invention provides a highly efficient heavy sludge separation system.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The bottom end of the cone section is provided with a heavy sludge outlet, the top end of the cyclone chamber is provided with a light sludge outlet, and the side of the cyclone chamber is connected to a sludge mixture inlet.

[0012] The bottom of the cone section is equipped with a U-shaped flow pipe. A flow connection pipe is provided between the U-shaped flow pipe and the inlet of the next stage sludge mixture. The sludge mixture inlet of the first stage cyclone separation unit is connected to the main inlet pipe, and the heavy sludge outlet of the third stage cyclone separation unit is connected to the underflow discharge port.

[0013] An overflow pipe is installed on the fixed frame, and the outlet of the light sludge is connected to the overflow pipe through a collection pipe.

[0014] Preferably, the U-shaped flow tube is movably mounted on the fixed frame, and one end of the U-shaped flow tube is movably connected to the flow connecting pipe, while the other end of the U-shaped flow tube is provided with an insertion interface, which corresponds to and matches the heavy sludge outlet.

[0015] Preferably, the U-shaped flow tube is movably mounted on a vertical guide rail on a fixed frame via a bracket, and a positioning bolt is fixed on the insertion interface. A rectangular opening is provided on the fixed frame, and the positioning bolt passes through the rectangular opening into the fixed frame.

[0016] Preferably, a guide ribbon is fixed on the inner wall of the swirling cavity, and the swirling cavity and the conical section are detachably connected by a flange.

[0017] Preferably, a quick-release lock is provided on the outside of the connector, and multiple locking elements arranged in a ring array are installed on the quick-release lock. The locking elements are provided with a first inclined surface, and a second inclined surface is provided on the outside of the heavy sludge outlet.

[0018] Preferably, a connecting member is fixed on the side of the locking member that is far apart from each other. The connecting member extends movably into the interior of the quick-release locker. A guide bar is fixed inside the quick-release locker, and a threaded rod is rotatably installed inside the quick-release locker. The guide bar passes through the connecting member through a guide hole, and the threaded rod passes through the connecting member through a threaded hole.

[0019] Preferably, a synchronizing gear ring is rotatably mounted on the inner wall of the top of the quick-release lock, and a synchronizing gear is fixed to the outside of the threaded rod, with multiple synchronizing gears meshing with the synchronizing gear ring.

[0020] Preferably, a rotary lock is fixed on one outer wall of the quick-release lock, one end of a threaded rod extends into the rotary lock, and a first disc is fixedly installed on the outside of the threaded rod at the inside position of the rotary lock, and a second disc is rotatably installed on the other end of the threaded rod extending to the outside of the rotary lock.

[0021] Preferably, a first ratchet and a second ratchet are fixed on the inner wall of the rotary lock, with the ratchet teeth of the first ratchet and the second ratchet facing opposite directions. A pair of parallel limiting protrusions are provided on each side of the first disc located on the threaded rod. A slider is slidably installed between the two pairs of limiting protrusions. An elastic telescopic rod is fixed between the side of the two sliders that are close to each other and the threaded rod. A first pawl and a second pawl are fixed on the side of the two sliders that are far apart from each other. The first pawl and the second pawl are staggered and correspond to the first ratchet and the second ratchet, respectively. A guide slope is provided on the slider.

[0022] Preferably, two levers are fixed on the side of the second disc near the interior of the rotary locker. The two levers extend into each gap of the two sets of limiting protrusions, and the side of the levers contacts the guide slope. A rotating handle is fixed on the side of the second disc away from the interior of the rotary locker.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. Through the optimized series connection of multi-stage adjustable units, the heavy sludge is purified in stages. The bottom flow (coarse separation product) of the previous stage enters the fine separation of the next stage, which effectively breaks through the limit of single-stage separation, greatly improves the purity and recovery rate of the final product, reduces the pollution of the target sludge by light flocs, and meets the requirements of subsequent treatment or resource utilization.

[0025] 2. Supports flexible configuration of the number of series stages (2-4 stages) and the number of parallel units. The processing capacity can be linearly expanded by connecting units of the same or different specifications in parallel to meet the needs of high flow rate scenarios. The separator specifications (25mm, 50mm, 75mm), cone angle (10°, 15°) and cascading method can be dynamically selected according to specific scenarios such as sludge density, particle size distribution, and processing volume to achieve the optimal balance between efficiency, purity and energy consumption, and solve the problem of poor adaptability of traditional equipment.

[0026] 3. It adopts a detachable vortex chamber-cone section dual-zone structure (flange connection), which can quickly respond to changes in the properties of influent sludge by replacing the cone section module or adjusting the cascade scheme without replacing the entire set of equipment. The inspection, cleaning and replacement of easily worn parts (such as the cone section) are convenient, reducing downtime and maintenance costs.

[0027] 4. Through the design of the quick-release locking device, the synchronous gear ring and synchronous gear drive multiple sets of locking parts to move synchronously. The cooperation of the first inclined surface and the second inclined surface realizes the tight locking between the heavy sludge outlet and the insertion interface, which has high disassembly and assembly efficiency and stable connection.

[0028] 5. Through the design of the rotary lock, the first ratchet, the second ratchet and the corresponding pawl cooperate to achieve forward and reverse self-locking of the threaded rod, avoiding loosening of the lock due to external forces such as vibration, and ensuring long-term stable operation of the system; at the same time, through the linkage of the lever and the guide slope, the lock can be easily released and the threaded rod can be driven to rotate, taking into account both stability and operational flexibility.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Reference Figure 1-14 A high-efficiency heavy sludge separation system, comprising a fixed frame 1, a primary cyclone separation unit 2, a secondary cyclone separation unit 201 and a tertiary cyclone separation unit 202, wherein the primary cyclone separation unit 2, the secondary cyclone separation unit 201 and the tertiary cyclone separation unit 202 are connected in series.

[0048] The first-stage cyclone separation unit 2, the second-stage cyclone separation unit 201, and the third-stage cyclone separation unit 202 all include a cyclone cavity 203 (pre-separation zone) and a cone section 204 (main separation zone);

[0049] The primary cyclone separation unit 2, the secondary cyclone separation unit 201, and the tertiary cyclone separation unit 202 can be combined with different sizes and models of cyclone chambers 203 and conical sections 204 according to actual needs. These include a series of separators with diameters of 25 mm, 50 mm, and 75 mm (type 25, type 50, and type 75 (type 75I has a cone angle of 10°, and type 75II has a cone angle of 15°)). A guide ribbon 2033 is fixed on the inner wall of the cyclone chamber 203. The cyclone chamber 203 and the conical section 204 are detachably connected by a flange 205. By combining different models of cyclone chambers 203 and conical sections 204, the height ratio and cone angle of the pre-separation zone and the main separation zone can be dynamically adjusted. The system achieves multi-stage collaborative separation of heavy sludge through series stage optimization and parallel unit configuration, solving the problems of low efficiency, high energy consumption, and poor adaptability of traditional equipment for heavy sludge separation.

[0050] The bottom end of the cone section 204 is provided with a heavy sludge outlet 2041, the top end of the cyclone chamber 203 is provided with a light sludge outlet 2031, and the side of the cyclone chamber 203 is connected to a sludge mixture inlet 2032.

[0051] The sludge mixture enters the vortex chamber 203 through the sludge mixture inlet 2032, generating a spiral. The guide ribbon 2033 further promotes the generation of the spiral. The sludge mixture rotates downwards along the outer wall, forming an outer vortex. In the underflow formed at the bottom of the cone, denser, heavy granular sludge and more compact sludge are left behind. The heavy sludge is discharged from the heavy sludge outlet 2041. Lighter, flocculent or filamentous sludge rotates upwards and is discharged from the light sludge outlet 2031, achieving the purpose of sludge separation.

[0052] The bottom end of the cone section 204 is provided with a U-shaped cross-flow pipe 4. A cross-flow connecting pipe 303 is provided between the U-shaped cross-flow pipe 4 and the sludge mixture inlet 2032 of the next stage. The sludge mixture inlet 2032 of the first-stage cyclone separation unit 2 is connected to the liquid inlet main pipe 3. The heavy sludge outlet 2041 of the third-stage cyclone separation unit 202 is connected to the underflow discharge port 302. An overflow pipe 301 is installed on the fixed frame 1. The light sludge outlet 2031 is connected to the overflow pipe 301 through the collecting pipe 3011.

[0053] The sludge is separated sequentially through a primary cyclone separation unit 2, a secondary cyclone separation unit 201, and a tertiary cyclone separation unit 202. Depending on the actual separation requirements, the number of stages can be set to 2-4.

[0054] The U-shaped flow tube 4 is movably mounted on the fixed frame 1, and one end of the U-shaped flow tube 4 is movably connected to the flow connecting pipe 303. The other end of the U-shaped flow tube 4 is provided with a plug interface 403, which corresponds to and matches the heavy sludge outlet 2041. The U-shaped flow tube 4 is movably mounted on the vertical guide rail 101 on the fixed frame 1 through the bracket 401, and a positioning bolt 402 is fixed on the plug interface 403. A rectangular opening 102 is opened on the fixed frame 1, and the positioning bolt 402 passes through the rectangular opening 102 through the fixed frame 1.

[0055] When disassembling and assembling the cyclone separator unit, first adjust the height of the U-shaped flow tube 4, align the heavy sludge outlet 2041 at the bottom of the cone section 204 of the cyclone separator unit with the insertion interface 403, then move the U-shaped flow tube 4 upward so that the light sludge outlet 2031 at the top of the cyclone chamber 203 connects with the collecting pipe 3011, and then lock the position of the U-shaped flow tube 4 with the nut and positioning bolt 402, thereby completing the installation and fixing of the cyclone separator unit.

[0056] Example 2

[0057] Reference Figure 1-14 The difference between this embodiment and embodiment 1 is that a quick-release lock 5 is provided on the outer side of the plug interface 403. Multiple locking members 504 arranged in a ring array are installed on the quick-release lock 5. The locking members 504 are provided with a first inclined surface. The outer side of the heavy sludge outlet 2041 is provided with a second inclined surface 2042. A connecting member 503 is fixed on the side of the locking members 504 that is far apart from each other. The connecting member 503 extends movably into the interior of the quick-release lock 5. A guide crossbar 502 is fixed inside the quick-release lock 5. A threaded rod 501 is rotatably installed inside the quick-release lock 5. The guide crossbar 502 passes through the connecting member 503 through the guide hole. The threaded rod 501 passes through the connecting member 503 through the threaded hole. A synchronous gear ring 506 is rotatably installed on the inner wall of the top of the quick-release lock 5. A synchronous gear 505 is fixed on the outside of the threaded rod 501. Multiple synchronous gears 505 mesh with the synchronous gear ring 506.

[0058] When one of the threaded rods 501 is rotated, the remaining threaded rods 501 can be driven to rotate synchronously through the engagement of the synchronous gear 505 with the synchronous gear ring 506. When the threaded rod 501 rotates, it can drive the connecting piece 503 to move horizontally, thereby driving multiple locking pieces 504 to move closer to each other. The locking pieces 504 can clamp and lock the heavy sludge outlet 2041. Due to the sliding fit between the first inclined surface and the second inclined surface 2042, the heavy sludge outlet 2041 will be pressed down during the clamping process to ensure a tight structure between the two.

[0059] Example 3

[0060] Reference Figure 1-14The difference between this embodiment and embodiment 2 is that a rotary lock 6 is fixed on one outer wall of the quick-release lock 5. One end of a threaded rod 501 extends into the rotary lock 6, and a first disc 605 is fixedly installed on the outside of the threaded rod 501 inside the rotary lock 6. Another end of the threaded rod 501 extends to the outside of the rotary lock 6 and is rotatably mounted on a second disc 601. A first ratchet 603 and a second ratchet 604 are fixed on the inner wall of the rotary lock 6, respectively. The ratchet teeth of the first ratchet 603 and the second ratchet 604 are in opposite directions. A pair of parallel limiting protrusions 607 are provided on each side of the first disc 605 located on the threaded rod 501. A slider 608 is slidably installed between the two pairs of limiting protrusions 607. On the side of each slider 608 that is close to each other, there is an elastic telescopic rod 5011 fixed between it and the threaded rod 501. On the side of each slider 608 that is far from each other, there is a first pawl 6081 and a second pawl 6082 respectively. The first pawl 6081 and the second pawl 6082 are staggered and match the first ratchet 603 and the second ratchet 604 respectively. The slider 608 is provided with a guide slope 6083. On the side of the second disc 601 that is close to the inside of the rotary locker 6, there are two levers 606. The two levers 606 extend into each gap of the two sets of limiting protrusions 607 respectively. The side of the levers 606 contacts the guide slope 6083. On the side of the second disc 601 that is far from the inside of the rotary locker 6, there is a rotating handle 602.

[0061] Due to the presence of the first ratchet 603 and the second ratchet 604, when the threaded rod 501 tends to rotate due to external factors such as vibration, the elastic telescopic rod 5011 will push the first pawl 6081 and the second pawl 6082 to engage with the first ratchet 603 and the second ratchet 604 respectively, so that the threaded rod 501 cannot actively rotate forward or backward, thereby ensuring that once the locking part 504 is locked, it will not loosen.

[0062] When it is necessary to drive the threaded rod 501 to rotate, hold the rotating handle 602 to drive the second disc 601 to rotate. Since the lever 606 is engaged between a pair of limiting protrusions 607, refer to... Figure 12 When the second disc 601 rotates clockwise, the left lever 606 will contact the left guide slope 6083 and push the left slider 608 to the right, causing the first pawl 6081 to separate from the first ratchet 603, thereby releasing the lock on the clockwise rotation of the threaded rod 501. If rotation continues, the lever 606 can push the limiting protrusion 607 to drive the first disc 605 to rotate, thereby driving the threaded rod 501 to rotate.

[0063] When the second disc 601 rotates counterclockwise, the principle is similar. The right lever 606 will first push the right slider 608 to move to the left, thereby separating the second pawl 6082 from the second ratchet 604, thus releasing the lock on the counterclockwise rotation of the threaded rod 501. Continuing to rotate will drive the threaded rod 501 to rotate counterclockwise.

[0064] The design of the rotary locker 6 ensures that the position of the threaded rod 501 is firmly locked when the second disc 601 is not actively rotated, achieving the purpose of forward and reverse self-locking. This ensures that once the quick-release locker 5 is locked, it will not loosen due to external forces such as vibration, making the installation more stable.
