Description

Technical Field

[0001] This application relates to the field of mud treatment technology, specifically a rapid sedimentation device for mud with a bottom scraper assembly. Background Technology

[0002] Large amounts of muddy water are generated during mineral processing, construction projects, and river dredging operations. Currently used sedimentation devices, such as ordinary sedimentation tanks, mainly rely on gravity for natural settling, which has problems such as slow settling speed, low treatment efficiency, and large footprint.

[0003] Existing sedimentation devices still require periodic shutdowns for manual cleaning of sludge deposited at the bottom of the tank, which is labor-intensive and has a long operating cycle. In addition, the existing mechanical sludge scraping equipment and rapid sedimentation structure are not well coordinated, and the sludge scraping components are generally inconvenient to maintain and prone to jamming.

[0004] Therefore, this application provides a rapid sedimentation device for mud with a bottom scraping assembly to solve the above-mentioned problems. Summary of the Invention

[0005] This application provides a rapid sedimentation device for sludge with a bottom scraping component, which aims to solve the problems mentioned in the background art. Existing sedimentation devices still require periodic shutdowns for manual cleaning of sludge deposited at the bottom of the tank, which is labor-intensive and has a long operation cycle. In addition, the existing mechanical scraping equipment and rapid sedimentation structure have insufficient coordination, and the scraping component is generally inconvenient to maintain and prone to jamming.

[0006] To achieve the above objectives, this application provides the following technical solution: a rapid sedimentation device for mud with a bottom scraping assembly, wherein the rapid sedimentation device for mud with a bottom scraping assembly includes a sedimentation mechanism;

[0007] To address the issue that existing sedimentation devices still require periodic shutdowns for manual cleaning of sludge deposited at the bottom of the tank, resulting in high labor intensity and long operation cycles, and the lack of coordination between existing mechanical sludge scraping equipment and rapid sedimentation structures, which commonly suffers from inconvenient maintenance and easy jamming of the scraping components, the sedimentation mechanism includes a sedimentation tank with a support rod fixedly connected to its exterior. The sedimentation tank has an inlet on one side of its top and an outlet on the other side. A sludge collection hopper is located at the bottom of the sedimentation tank, with a drain outlet at its bottom and a drain valve at its bottom. A sealing cover is installed at the top of the sedimentation tank, with a servo motor fixedly connected to its top. The output end of the servo motor extends into the interior of the sealing cover and is fixedly connected to a rotating shaft. A mounting groove is fixedly connected to the bottom of the rotating shaft. The sedimentation tank has mounting blocks on both sides inside the tank. A horizontal scraper is fixedly connected to the side of each mounting block, and a vertical scraper is fixedly connected to the top of each horizontal scraper. Wastewater enters the sedimentation tank through the inlet and is driven to rotate by a servo motor on the top of the sealing cover. This rotation causes the horizontal scrapers on both sides to rotate, and the horizontal and vertical scrapers in turn rotate. The horizontal and vertical scrapers scrape away sludge from the bottom and inner walls of the sedimentation tank. The horizontal scrapers drive the sludge into the collection hopper for collection, and the sludge is discharged through the discharge port and a discharge valve inside the discharge port. The rotation of the horizontal scrapers inside the sedimentation tank causes the water to rotate, and the upper layer of water is discharged through the inlet. This system can clean the settled sludge during wastewater treatment, is simple and quick to operate, and is easy to install and disassemble.

[0008] Preferably, in order to solve the problem of convenient sludge collection, the sludge collection hopper is located at the center of the bottom surface inside the sedimentation tank, and the top of the sludge collection hopper is flush with the bottom surface of the sedimentation tank. The flush setting of the sludge collection hopper with the sedimentation tank can facilitate the entry of sludge into the sludge collection hopper for easy collection.

[0009] Preferably, to address the issue of easy cleaning, the two sets of transverse scrapers are symmetrically arranged, with the bottom surface of the transverse scrapers fitting against the bottom surface of the sedimentation tank. The two sets of longitudinal scrapers are fixed to the top of the transverse scrapers by bolts, and the longitudinal scrapers are symmetrically arranged, with the sides of the longitudinal scrapers fitting against the inner wall of the sedimentation mechanism. The symmetrical arrangement of both the transverse and longitudinal scrapers facilitates the cleaning of sludge from the bottom surface and inner wall of the sedimentation tank, making it convenient to use.

[0010] Preferably, to address the issue of convenient installation and disassembly of the transverse scraper, the mounting block and the mounting groove block are slotted together. A fixing rod is provided inside the mounting block, and a fixing groove is provided at the top of the mounting groove block. The fixing rod is inserted into the fixing groove. A spring is provided between the end of the fixing rod inside the mounting block and the mounting block. Pressing the fixing rod causes it to slide outside the limiting rod under force. Compressing the spring at one end of the fixing rod causes it to enter the interior of the mounting block. When the mounting block is inserted into the slot of the mounting groove block, the fixing rod, under the rebound force of the spring, engages with the fixing groove at the top of the mounting groove block. This secures the mounting block and the mounting groove block, facilitating the installation and disassembly of the transverse scraper. The operation is simple, quick, and convenient.

[0011] Preferably, in order to solve the problem of convenient operation of the fixing rod, a limiting rod is fixedly connected inside the mounting block. The fixing rod is located inside the mounting block at one end and on both sides outside the limiting rod. The fixing rod and the limiting rod are slidably connected. The limiting rod can improve the stability of the movement of the fixing rod.

[0012] This sedimentation mechanism allows wastewater to enter the sedimentation tank through the inlet. A servo motor mounted on the top of the sealed cover drives a rotating shaft, which in turn rotates horizontal scrapers on both sides. These horizontal and vertical scrapers scrape away sludge from the bottom and inner walls of the sedimentation tank. The horizontal scrapers then drive the sludge into a collection hopper for collection, and finally discharge it through a drain outlet and a drain valve inside the outlet. The rotation of the horizontal scrapers within the sedimentation tank causes the water to swirl, and the upper layer of water is discharged through the inlet. This mechanism effectively cleans the settled sludge during wastewater treatment, offering simple and quick operation, easy installation and disassembly, and convenient use.

[0013] This sedimentation mechanism, when pressed, causes the fixing rod to slide outside the limiting rod under force. The fixing rod compresses a spring at one end, causing it to enter the interior of the mounting block. The mounting block is then inserted into the slot of the mounting groove. The fixing rod, under the rebound force of the spring, engages with the fixing slot at the top of the mounting block, thus fixing the mounting block to the mounting groove. This facilitates the installation and removal of the transverse scraper, making the operation simple, quick, and convenient. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0022] This embodiment provides a rapid sedimentation device for sludge with a bottom scraping assembly, such as... Figure 1-5 As shown, the rapid sedimentation device for mud with bottom scraping assembly includes a sedimentation mechanism 1.

[0023] The sedimentation mechanism 1 can be used to clean the sedimented sludge during the wastewater treatment process. It is simple and quick to operate, easy to install and disassemble, and convenient to use.

[0024] Specifically, the sedimentation mechanism 1 includes a sedimentation tank 11, a support rod 12 fixedly connected to the outside of the sedimentation tank 11, an inlet 13 on one side of the top of the sedimentation tank 11, an outlet 14 on the other side of the top of the sedimentation tank 11, a sludge collection hopper 15 at the bottom of the sedimentation tank 11, a sludge discharge port 16 at the bottom of the sludge collection hopper 15, a sludge discharge valve 17 at the bottom of the sludge discharge port 16, a sealing cover 18 at the top of the sedimentation tank 11, a servo motor 19 fixedly connected to the top of the sealing cover 18, a rotating shaft 20 fixedly connected to the output end of the servo motor 19 extending into the interior of the sealing cover 18, an installation groove block 21 fixedly connected to the bottom of the rotating shaft 20, installation blocks 22 on both sides inside the installation groove block 21, a transverse scraper 23 fixedly connected to the side of the installation block 22, and a longitudinal scraper 24 fixedly connected to the top of the transverse scraper 23.

[0025] In use, wastewater enters the sedimentation tank 11 through the inlet 13, and the servo motor 19 on the top of the sealing cover 18 drives the rotating shaft 20 to rotate. This causes the rotating shaft 20 to rotate the transverse scrapers 23 on both sides, which in turn drive the longitudinal scrapers 24 to rotate. The transverse scrapers 23 and longitudinal scrapers 24 can scrape away the sludge from the bottom surface and inner wall of the sedimentation tank 11. The transverse scrapers 23 drive the sludge into the collection hopper 15 for collection, and the sludge is discharged through the discharge port 16 and the discharge valve 17 inside the discharge port 16. 3. The water rotates inside the sedimentation tank 11, causing the water to rotate. The upper layer of water is discharged through the inlet 13. This can clean the settled sludge during the sewage treatment process. The operation is simple and quick, and it is easy to install and disassemble. The sedimentation tank 11 has a cylindrical structure, preferably with a diameter of 1.5m and a height of 1.8m. The wall thickness of the sedimentation tank 11 is 8-12mm. It is made of stainless steel 304 or corrosion-resistant polyethylene material to ensure structural strength and corrosion resistance. The bottom of the sedimentation tank 11 is designed to transition to the sludge collection hopper 15 in a conical shape with a cone angle of 30°-45°, which facilitates the sludge to slide and collect.

[0026] Furthermore, the sludge collection hopper 15 is located at the center of the bottom surface inside the sedimentation tank 11, with the top of the sludge collection hopper 15 flush with the bottom surface of the sedimentation tank 11. The flush arrangement of the sludge collection hopper 15 with the sedimentation tank 11 facilitates the entry of sludge into the sludge collection hopper 15 for easy collection.

[0027] Furthermore, the two sets of transverse scrapers 23 are symmetrically arranged, and the bottom surface of the transverse scrapers 23 is in contact with the inner bottom surface of the sedimentation tank 11. The two sets of longitudinal scrapers 24 are fixed to the top of the transverse scrapers 23 by bolts, and the longitudinal scrapers 24 are symmetrically arranged. The sides of the longitudinal scrapers 24 are in contact with the inner wall of the sedimentation mechanism 1. The symmetrical arrangement of the transverse scrapers 23 and the longitudinal scrapers 24 facilitates the cleaning of sludge on the bottom surface and inner wall of the sedimentation tank 11, making it easy to use. The transverse scraper 23 is a long strip plate, the length of which matches the radius of the sedimentation tank 11. The bottom is inlaid with a wear-resistant rubber strip to ensure elastic contact with the bottom surface of the tank and reduce wear. The longitudinal scraper 24 is an arc-shaped plate with a curvature consistent with the inner wall of the sedimentation tank 11. It is adjustablely connected to the transverse scraper 23 by bolts, allowing for height adjustment according to the wear of the tank wall. The surfaces of the transverse scrapers 23 and the longitudinal scrapers 24 are coated with polytetrafluoroethylene to reduce frictional resistance. Example 2

[0028] Unlike Embodiment 1, in order to solve the problem of easy installation and disassembly of the transverse scraper 23, the mounting block 22 and the mounting groove block 21 are slotted and inserted into each other. The mounting block 22 is provided with a fixing rod 25 inside. The top of the mounting groove block 21 is provided with a fixing groove 26. The fixing rod 25 is inserted into the fixing groove 26. A spring 28 is provided between the end of the fixing rod 25 inside the mounting block 22 and the mounting block 22.

[0029] In use, press the fixing rod 25, causing it to slide outside the limiting rod 27 under force. The fixing rod 25 compresses the spring 28 at one end, causing it to enter the interior of the mounting block 22. The mounting block 22 is then inserted into the groove of the mounting slot block 21. The fixing rod 25 is subjected to the rebound force of the spring 28, causing it to engage with the fixing slot 26 at the top of the mounting slot block 21. This fixes the mounting block 22 to the mounting slot block 21, facilitating the installation and removal of the transverse scraper 23. The operation is simple, quick, and convenient.

[0030] Furthermore, a limiting rod 27 is fixedly connected inside the mounting block 22. A fixing rod 25 is located inside the mounting block 22, with one end and both sides located outside the limiting rod 27. The fixing rod 25 and the limiting rod 27 are slidably connected. The limiting rod 27 can improve the stability of the movement of the fixing rod 25.

[0031] Wastewater enters sedimentation tank 11 through inlet 13 at a flow rate of 0.5-1.0 m³ / h. Servo motor 19 drives shaft 20 to rotate at 5-8 rpm, which drives the sludge scraping assembly to scrape sludge to collection hopper 15. The upper layer of clear water overflows and is discharged through outlet 14. Its flow rate is controlled below 0.2 m / s to reduce disturbance. The drain valve 17 is a pneumatic butterfly valve that automatically opens once every 24 hours to discharge concentrated sludge.

[0032] It should be noted that the servo motor 19 is an existing device. The servo motor 19 is a geared AC servo motor with a rated power of 1.5kW and an output speed of 5-10 rpm. Stepless speed regulation is achieved through a frequency converter. The servo motor 19 is connected to a PLC controller, and the preset sludge scraping cycle is 10 minutes of operation every 2 hours. Its working principle, size and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
