Description

Technical Field

[0001] This utility model relates to the technical field of solid-liquid separation scraper, and in particular to a high-efficiency and energy-saving sedimentation type solid-liquid separation scraper. Background Technology

[0002] The solid-liquid separation sludge scraper is a core piece of equipment used in the field of water treatment. Its main function is to separate and collect the settled solid sludge from the water through physical means, thereby achieving efficient separation of clean water and sludge and providing a foundation for subsequent water treatment processes. By using an energy-saving variable frequency motor for drive, energy-saving effects can be achieved.

[0003] The existing sludge scraping mechanism cannot remove the sludge from the scraper blade in a timely manner during the sludge scraping process, resulting in more and more sludge accumulating.

[0004] Existing patent (publication number: CN213253158U) discloses a sludge scraping mechanism for a sludge scraper. This utility model utilizes a scraper bar with eight scraping plates inside for scraping sludge. Each scraping plate has a rotating rod inside. When a large amount of sludge adheres to the lower surface of the scraping plate, removing a locking pin rotates the rod, causing the scraping plate to rotate 180 degrees, allowing it to continue scraping. During this rotation, a cleaning strip removes the sludge from the lower surface of the scraping plate. The spring mechanism on the cleaning strip further facilitates this process. The scraper blades, which deform and rebound upon impact, allow for easier cleaning of the overturned scraper. A lifting mechanism facilitates the descent of the scraper to the bottom of the treatment tank for sludge removal. A brake controls the scraper's deceleration or stopping during lifting, preventing inertia from hindering timely intervention. A clamping collar and a tensioning adjustment mechanism ensure a more secure connection between the scraper and the rotating shaft, while the tensioning adjustment mechanism controls the rope's release and retraction, improving scraping efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the scrapers of some existing high-efficiency and energy-saving sedimentation solid-liquid separation scrapers are fixedly installed. When the scrapers wear out, it is inconvenient for them to automatically move down to compensate for the gap between the scraper and the bottom of the sedimentation tank, which affects the sludge removal effect. Furthermore, fixing the scrapers requires multiple screws and nuts, which is time-consuming when replacement is needed.

[0006] Therefore, a high-efficiency and energy-saving sedimentation-type solid-liquid separation sludge scraper is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a high-efficiency and energy-saving sedimentation solid-liquid separation sludge scraper, which can solve the problems of the scraper blades of some existing high-efficiency and energy-saving sedimentation solid-liquid separation sludge scrapers being fixedly installed. When the scraper blades are worn, it is inconvenient to automatically move down to compensate for the gap between the scraper blades and the bottom of the sedimentation tank, which affects the sludge scraping effect. In addition, fixing the scraper blades requires multiple screws and nuts, which is time-consuming when replacement is needed.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving sedimentation solid-liquid separation sludge scraper, comprising two fixed frames, a transmission box disposed between the tops of the two fixed frames, a transmission shaft disposed at the bottom of the transmission box, an energy-saving variable frequency motor disposed at the top of the transmission box, a scraping mechanism disposed at the bottom of the fixed frames, the number of scraping mechanisms being several and evenly distributed at the bottom of the fixed frames, and a jacking mechanism disposed at the top of the scraping mechanism;

[0009] The jacking mechanism includes two slide rods, a tension spring, and a fixed plate. The bottom of the slide rod is fixedly connected to the top of the fixed plate. The tension spring is movably sleeved on the surface of the slide rod, and the top of the tension spring is fixedly connected to the surface of the slide rod.

[0010] Preferably, the scraping mechanism includes two limiting buttons, two first connecting blocks, a slot, two second connecting blocks, and a scraper. The side of the second connecting block closest to the scraper is fixedly connected to the scraper, and the side of the first connecting block closest to the fixed plate is fixedly connected to the fixed plate. The slot is opened inside the fixed plate, and the scraper is movably inserted into the slot. The bottom of the limiting button passes through the first connecting block and is threadedly connected to the inside of the second connecting block.

[0011] Preferably, the scraper is made of ultra-high molecular weight polyethylene.

[0012] Preferably, the fixing frame has a sliding hole inside for use with the sliding rod, and the sliding rod is slidably connected inside the sliding hole.

[0013] Preferably, a sliding sleeve is fixedly connected between the two fixed brackets on opposite sides, and the sliding sleeve is movably sleeved on the surface of the drive shaft.

[0014] Preferably, the front and rear sides of the sliding sleeve are provided with limit screws, and the number of limit screws is several and evenly distributed on the front and rear sides of the sliding sleeve. The front and rear sides of the drive shaft are provided with limit holes for use with the limit screws. The side of the limit screw near the sliding sleeve passes through the sliding sleeve and extends into the interior of the limit hole. The surface of the limit screw is connected to the internal thread of the sliding sleeve. The limit screw, the sliding sleeve and the drive shaft are all made of high-strength steel.

[0015] Preferably, a lifting ring is fixedly connected to the top of the fixing frame, and a cable is fixedly connected to the top of the fixing frame, with the side of the cable near the drive shaft being fixedly connected to the surface of the drive shaft.

[0016] Preferably, the bottom of the output shaft of the energy-saving variable frequency motor is fixedly connected to the input shaft of the transmission box, and the bottom of the output shaft of the transmission box is fixedly connected to the top of the transmission shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a top-moving mechanism, which relies on the sliding cooperation between the slide rod and the sliding hole of the fixed frame to provide stable guidance for its own movement. Its core is to apply a continuous tension force to the slide rod through the tension spring, so that the slide rod always maintains a downward trend, thereby driving the connected fixed plate and scraper to continuously have downward pressure. This design can ensure that the bottom of the scraper is always in close contact with the bottom of the sedimentation tank. Even if the scraper wears slightly after long-term use, it can still automatically compensate for the gap between it and the bottom of the sedimentation tank under the tension of the tension spring, maintain a good contact state, effectively avoid the problem of reduced sludge scraping effect due to poor contact, fully extend the service life and utilization rate of the scraper, and ensure stable sludge scraping efficiency.

[0019] 2. This application utilizes a scraping mechanism to achieve quick positioning and insertion of the scraper and the fixed plate via a slot. The first and second connecting blocks are then threaded together using limit buttons, ensuring a secure and stable installation with a simple structure. The scraper is made of ultra-high molecular weight polyethylene, which offers excellent wear resistance, corrosion resistance, and a low coefficient of friction, reducing sludge adhesion and extending its service life. Replacement is simple; only two limit buttons need to be removed to remove the scraper from the slot, eliminating the need for complex operations. This solves the problem of existing scraper fixation relying on multiple sets of screws and nuts and time-consuming replacement. Furthermore, the jacking mechanism further ensures effective sludge scraping and prevents scraper wear from affecting the solid-liquid separation efficiency of wastewater.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A high-efficiency and energy-saving sedimentation solid-liquid separation sludge scraper includes two fixed frames 1, a transmission box 2 is arranged between the tops of the two fixed frames 1, a transmission shaft 9 is arranged at the bottom of the transmission box 2, an energy-saving variable frequency motor 4 is arranged at the top of the transmission box 2, a scraping mechanism 5 is arranged at the bottom of the fixed frames 1, the number of scraping mechanisms 5 is several and evenly distributed at the bottom of the fixed frames 1, and a jacking mechanism 6 is arranged at the top of the scraping mechanism 5.

[0030] The jacking mechanism 6 includes two slide rods 601, a tension spring 602, and a fixing plate 603. The bottom of the slide rod 601 is fixedly connected to the top of the fixing plate 603. The tension spring 602 is movably sleeved on the surface of the slide rod 601, and the top of the tension spring 602 is fixedly connected to the surface of the slide rod 601.

[0031] In this embodiment: High-efficiency and energy-saving operation is achieved through the energy-saving variable frequency motor 4. The operator can precisely control the speed of the energy-saving variable frequency motor 4 according to the thickness and type of sludge using an external controller. When the sludge is thick or viscous, the speed is increased to enhance efficiency; conversely, the speed is reduced to decrease energy consumption. The power of the energy-saving variable frequency motor 4 is transmitted to the transmission shaft 9 via the transmission box 2. The sliding sleeve 7 is fixed to the transmission shaft 9 by the engagement of the limiting screw 8 and the limiting hole 10, driving the fixed frame 1 to rotate. In the scraping mechanism 5, the limiting button 501 connects the first and second connecting blocks to fix the ultra-high molecular weight polyethylene scraper 505. The tension spring 602 of the jacking mechanism 6, through the sliding rod 601, ensures that the scraper 505 is always in close contact with the bottom of the pool. To ensure effective sludge removal, when replacing scraper 505, remove the limit screw 8, connect it to the lifting ring 11 via external hoisting equipment, move the hoisting fixing frame 1 and sliding sleeve 7 upwards, then remove the limit button 501, and take scraper 505 out of the slot 503. The replacement can be completed by reversing the operation. Replacing a single scraper 505 only requires turning two limit buttons 501, which is convenient and quick. This solves the problem that in some existing high-efficiency energy-saving sedimentation solid-liquid separation sludge scrapers, the scrapers are fixedly installed. When the scraper is worn, it is inconvenient to automatically move down to compensate for the gap between the scraper and the bottom of the sedimentation tank, which affects the sludge removal effect. In addition, fixing the scraper requires multiple screws and nuts, which is time-consuming when replacement is needed.

[0032] Specifically, such as Figure 3 As shown, the scraping mechanism 5 includes two limit buttons 501, two first connecting blocks 502, a slot 503, two second connecting blocks 504, and a scraper 505. The side of the second connecting block 504 near the scraper 505 is fixedly connected to the scraper 505. The side of the first connecting block 502 near the fixing plate 603 is fixedly connected to the fixing plate 603. The slot 503 is opened inside the fixing plate 603. The scraper 505 is movably inserted into the slot 503. The bottom of the limit button 501 passes through the first connecting block 502 and is threadedly connected to the inside of the second connecting block 504.

[0033] Specifically, such as Figure 3 As shown, scraper 505 is made of ultra-high molecular weight polyethylene.

[0034] In this embodiment: the scraping mechanism 5 achieves quick positioning of the scraper 505 and the fixing plate 603 through the slot 503, and then the first connecting block 502 and the second connecting block 504 are threaded through the limit button 501 to firmly fix the scraper 505 and facilitate subsequent disassembly and replacement. The scraper 505 is made of ultra-high molecular weight polyethylene, which has excellent wear resistance, corrosion resistance and low friction coefficient, which can reduce sludge adhesion, extend the service life of the scraper 505 and ensure long-term stable sludge scraping effect.

[0035] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, the inside of the fixing frame 1 is provided with a sliding hole 12 that is used to cooperate with the slide rod 601, and the slide rod 601 is slidably connected inside the sliding hole 12.

[0036] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a sliding sleeve 7 is fixedly connected between the two fixed brackets 1 on opposite sides, and the sliding sleeve 7 is movably sleeved on the surface of the drive shaft 9.

[0037] Specifically, such as Figure 4 and Figure 5 As shown, the front and rear sides of the sliding sleeve 7 are provided with limit screws 8. There are several limit screws 8, which are evenly distributed on the front and rear sides of the sliding sleeve 7. The front and rear sides of the drive shaft 9 are provided with limit holes 10 that cooperate with the limit screws 8. The side of the limit screw 8 near the sliding sleeve 7 passes through the sliding sleeve 7 and extends into the interior of the limit hole 10. The surface of the limit screw 8 is connected to the internal thread of the sliding sleeve 7. The limit screws 8, the sliding sleeve 7 and the drive shaft 9 are all made of high-strength steel.

[0038] In this embodiment: the sliding hole 12 of the fixed frame 1 is slidably engaged with the sliding rod 601, providing stable guidance for the sliding rod 601 and ensuring that the jacking mechanism 6 can smoothly drive the scraper 505 to adjust its position. The sliding sleeve 7 is movably fitted with the transmission shaft 9. The limiting screw 8 passes through the sliding sleeve 7 and extends into the limiting hole 10 of the transmission shaft 9 and is threadedly connected. This allows for flexible fixing or adjustment of the relative position of the sliding sleeve 7 and the transmission shaft 9, adapting to different working conditions. Furthermore, the limiting screw 8, the sliding sleeve 7, and the transmission shaft 9 are all made of high-strength steel, with high structural strength, capable of withstanding the load during power transmission and rotation of the fixed frame 1, thus preventing component deformation and damage.

[0039] Specifically, such as Figure 6 As shown, a lifting ring 11 is fixedly connected to the top of the fixed frame 1, and a cable 3 is fixedly connected to the top of the fixed frame 1. The side of the cable 3 near the drive shaft 9 is fixedly connected to the surface of the drive shaft 9.

[0040] Specifically, such as Figure 1 As shown, the bottom of the output shaft of the energy-saving variable frequency motor 4 is fixedly connected to the input shaft of the transmission box 2, and the bottom of the output shaft of the transmission box 2 is fixedly connected to the top of the transmission shaft 9.

[0041] In this embodiment: the lifting ring 11 at the top of the fixed frame 1 facilitates the connection of external hoisting equipment, providing convenience for the lifting operation when replacing the scraper 505. The cable 3 connects the fixed frame 1 and the drive shaft 9, which can play a traction and stabilizing role for the fixed frame 1, making the fixed frame 1 more stable when rotating. The output shaft of the energy-saving variable frequency motor 4 is fixedly connected to the input shaft of the transmission box 2 and the output shaft of the transmission box 2 is fixedly connected to the top of the drive shaft 9, which can realize efficient power transmission and provide reliable rotational power for the operation of the fixed frame 1. The energy-saving variable frequency motor 4 achieves energy saving by combining with the frequency conversion characteristics of the energy-saving variable frequency motor 4.

[0042] Working Principle: The system achieves high-efficiency and energy-saving operation through its core power component, the energy-saving variable frequency motor 4. Specifically, operators can precisely control the speed of the energy-saving variable frequency motor 4 via an external controller based on the actual thickness and type of sludge in the sedimentation tank. When the sludge is thick or viscous, the motor speed can be appropriately increased to enhance scraping force and efficiency. When the sludge is thin or loose, the motor speed is reduced to decrease energy consumption and avoid unnecessary energy waste, fully demonstrating its high efficiency and energy-saving characteristics. The bottom of the output shaft of the energy-saving variable frequency motor 4 is fixedly connected to the input shaft of the transmission box 2. After the motor starts, it transmits power to the transmission box 2, which then performs corresponding transmission and conversion before delivering the power to the input shaft fixed to the bottom of the output shaft of the transmission box 2. The connected drive shaft 9 enables efficient power transmission from the energy-saving variable frequency motor 4 to the drive shaft 9, facilitating the rotation of the sliding sleeve 7, the fixed frame 1, and the scraper 505 to remove sludge from the bottom of the sedimentation tank. A limiting screw 8 passes through the sliding sleeve 7 near the side of the sliding sleeve 7 and extends into the limiting hole 10. The surface of the limiting screw 8 is threaded into the inside of the sliding sleeve 7. Through the engagement of the limiting screw 8 and the limiting hole 10, the sliding sleeve 7 and the drive shaft 9 can be fixed relative to each other, allowing the fixed frame 1 to rotate together with the drive shaft 9. The limiting screw 8, the sliding sleeve 7, and the drive shaft 9 are all made of high-strength steel, ensuring sufficient structural strength during power transmission and equipment operation. A cable 3 is fixedly connected to the top of the fixed frame 1, with one end of the cable 3 near the drive shaft 9... The side is fixedly connected to the surface of the drive shaft 9. The cable 3 can provide auxiliary traction for the fixed frame 1 to prevent the fixed frame 1 from shaking during the rotation of the drive shaft 9. The bottom of the fixed frame 1 is provided with several evenly distributed scraping mechanisms 5. Through the connection of the limit button 501, the first connecting block 502 and the second connecting block 504 are connected, so that the scraper 505 is stably installed on the fixed plate 603. The scraper 505 is made of ultra-high molecular weight polyethylene, which has excellent wear resistance, corrosion resistance and low coefficient of friction, which can effectively improve the service life of the scraper 505, reduce the adhesion of sludge on the surface of the scraper 505 and ensure the sludge scraping effect. The top of the scraping mechanism 5 is provided with a pushing mechanism 6, and the slide rod 601 is slidably connected to the top of the scraping mechanism 5. Inside the sliding hole 12, during equipment operation, the tension spring 602 exerts a continuous pulling force on the sliding rod 601, causing the sliding rod 601 to maintain a downward trend within the sliding hole 12. This, in turn, drives the fixed plate 603 and the scraper 505 connected to the fixed plate 603 to maintain downward pressure, ensuring that the bottom of the scraper 505 remains in close contact with the bottom of the sedimentation tank. Even if the scraper 505 experiences slight wear during long-term use, the tension spring 602 ensures that the scraper 505 still maintains good contact with the bottom of the sedimentation tank, effectively improving the sludge scraping effect. This prevents the scraper 505 from being unable to make proper contact with the bottom of the sedimentation tank after wear, thus ensuring that the scraper 505 can be fully utilized. When the scraper 505 needs to be replaced...First, remove the limiting screws 8 on the sliding sleeve 7 to release the fixed relationship between the sliding sleeve 7 and the drive shaft 9. Since the top of the fixed frame 1 is fixedly connected to the lifting ring 11, use an external lifting device to connect with the lifting ring 11. Through the action of the lifting device, the fixed frame 1 and the sliding sleeve 7 can be moved upward along the drive shaft 9, so that the scraper 505 is removed from the bottom of the sedimentation tank. Then, simply remove the two limiting buttons 501 on the scraping mechanism 5 to release the fixation between the first connecting block 502 and the second connecting block 504, and the scraper 505 can be removed downward from the slot 503 of the fixed plate 603. This completes the removal of the scraper 505. Then, install the new scraper 505 in the slot 503 in the reverse order, tighten the limiting buttons 501, and then use the lifting device to move the fixed frame 1 and the sliding sleeve 7 downward along the drive shaft 9 to a suitable position. Tighten the limiting buttons again. Screw 8 completes the replacement of scraper 505, restoring the equipment to normal operation. Disassembling a single scraper 505 only requires turning two limit buttons 501, making scraper 505 replacement convenient and quick. This solves the problem of some existing high-efficiency energy-saving sedimentation solid-liquid separation scrapers having fixed scraper installations. When the scraper wears down, it is inconvenient to automatically move down to compensate for the gap between the scraper and the bottom of the sedimentation tank, affecting the sludge removal effect. Furthermore, fixing the scraper requires multiple screws and nuts, making replacement time-consuming. It should be noted that the energy-saving variable frequency motor 4 and the transmission box 2 are both existing, published, and mature technologies. The energy-saving variable frequency motor 4 is powered by an external power supply and controlled by an external controller. Content not described in detail in this manual belongs to existing technology known to those skilled in the art, and its basic mechanisms are not elaborated here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
