Abstract
Description
Technical Field
[0001] This utility model relates to the field of separation tank technology, and in particular to a static sedimentation separation tank. Background Technology
[0002] In existing static sedimentation separation tank technology, this type of device is widely used in various industrial fields, such as sewage treatment, mining extraction, and chemical production, to achieve effective solid-liquid separation. Its basic working principle relies on gravity sedimentation, which causes the solid particles suspended in the liquid to gradually settle to the bottom of the tank in a static state, while the supernatant is discharged through a specific outlet, thereby achieving the purpose of separation.
[0003] However, existing static sedimentation separators have certain shortcomings in the drainage process. When the supernatant is discharged through the drain port, due to the disturbance of the liquid flow or the insufficient clarity of the interface between the precipitate and the liquid, some of the precipitated solid particles are often carried back into the liquid and discharged with the supernatant. This not only reduces the efficiency of solid-liquid separation, but may also have adverse effects on subsequent processing, such as clogging pipes and affecting product quality.
[0004] Therefore, there is an urgent need to provide a static sedimentation separation tank to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a static sedimentation separation tank.
[0006] To solve the above-mentioned technical problems, the present invention provides a static sedimentation separation tank, including a tank body, a screen rotatably connected inside the tank body, a sliding rod rotatably connected at the center of the front end of the screen, a pulling mechanism located at the front end of the sliding rod rotatably connected at the center of the front end of the screen, a sleeve fixedly connected to the outside of the sliding rod, a positioning mechanism slidably connected inside the sleeve, and a reset mechanism fixedly connected to the bottom end of the sliding rod.
[0007] A shielding mechanism is fixedly connected to the rear end of the screen.
[0008] The present invention is further configured such that: the top of the tank is fixedly connected to a feed inlet that communicates with it, the front end of the tank is fixedly connected to a drain outlet, the bottom of the tank is fixedly connected to a discharge outlet, and the screen has multiple holes arranged in a circular array.
[0009] The above technical solution allows for easy injection of the liquid to be settled into the tank, while the drain outlet is used to smoothly discharge the supernatant, and the discharge outlet is specifically used to discharge the sediment deposited at the bottom of the tank. In addition, the perforations are designed to reduce the interference of the screen on the water flow when it rotates in the tank, thus avoiding any impact on the sediment at the bottom of the tank.
[0010] The present invention is further configured such that: the pulling mechanism includes a first bracket fixedly connected to the center of the front end of the screen; a second rod rotatably connected inside the first bracket and sliding inside the sleeve; the second rod is located at the front end of the sliding rod; an electric push rod is installed on the inner top of the tank; the output end of the electric push rod is fixedly connected to the top of the sliding rod; a protective cover fixedly connected to the inner top of the tank and slidingly connected to the sleeve; and the electric push rod is located inside the protective cover.
[0011] Through the above technical solution, the function of the pulling mechanism is to drive the screen to rotate from an initial state perpendicular to the ground to a position parallel to the ground inside the tank. Initially, the screen is perpendicular to the ground, ensuring that the sediment can settle naturally without disturbance. When it is necessary to discharge the supernatant, to prevent the bottom sediment from being discharged upwards, the operator pulls rod two to raise it. Since the sliding rod is relatively fixed, this action causes the first support to deflect, thereby driving the screen from a vertical to a horizontal state. Subsequently, the relative position of the sliding rod and rod two is locked by the cooperation of the fixing block and the fixing hole. Next, the electric push rod is activated by program control. This part involves software control and is existing technology. The electric push rod works, driving the sliding rod to slowly descend, while simultaneously driving the sleeve... The cylinder slides within the protective cover; the cover not only guides the cylinder but also protects the electric push rod from damage; as the electric push rod slowly advances, the horizontal screen gradually descends; the holes in the screen and the slow movement of the electric push rod effectively reduce the screen's interference with the water flow and sediment at the bottom of the tank; until the screen moves above the sediment, the rotating baffle covers the screen holes, at which point the screen acts as a barrier, isolating the sediment from the supernatant and reducing the disturbance of the water flow to the sediment during drainage; when the screen needs to be reset, the electric push rod drives the sliding rod upward, moving the screen upward, and by unlocking the fixing block and fixing hole, the screen can rotate and reset to its initial position, ready for the next operation; the whole process is simple, practical, and efficient.
[0012] The present invention is further configured such that: the positioning mechanism includes a cylinder two fixedly connected inside the rod two; a fixed block with an inclined rear end is slidably connected inside the cylinder two; the rear end of the fixed block contacts and abuts against the sliding rod; an L-shaped rod is fixedly connected to the front end of the fixed block; a spring is provided between the front end of the fixed block and the cylinder two and sleeved on the outside of the L-shaped rod; the two ends of the spring are fixedly connected to the fixed block and the cylinder two respectively; and a fixing hole corresponding to the fixed block is opened at the front end of the sliding rod.
[0013] Through the above technical solution, the main function of the positioning mechanism is to stabilize the relative position between rod two and the sliding rod. When the operator pulls rod two upward, the connected cylinder two and its internal fixing block rise synchronously. During this process, the fixing block is pressed between the sliding rod and cylinder two, while compressing the spring. Until the fixing block aligns with the fixing hole, the fixing block pops out and embeds into the fixing hole with the help of the spring's restoring force, thus firmly locking the relative position between the sliding rod and rod two. To release this locking state, simply pull the L-shaped rod to disengage the fixing block from the fixing hole, and it will be easily unlocked. The advantage of the operator manually operating rod two is that they can flexibly control the rotation speed of the screen as needed, avoiding too fast or too slow operation and ensuring the accuracy of the operation. At the same time, manual operation also allows the operator to observe the internal condition of the tank while rotating the screen, and promptly identify and solve problems. This operation method is convenient, quick, and highly practical.
[0014] The present invention is further configured such that: the front end of the sleeve is provided with a second groove, and the bottom of the front end of the protective cover is provided with a third groove.
[0015] Through the above technical solution, the design of the second groove is to accommodate the second cylinder and allow the second cylinder to slide smoothly inside the sleeve; while the third groove plays a supporting and guiding role, ensuring that the second cylinder can slide smoothly inside the protective cover.
[0016] The present invention is further configured such that: the reset mechanism includes a second bracket fixedly connected to the center of the front end of the screen, and a second shaft fixedly connected to the bottom of the sliding rod is rotatably connected inside the second bracket. A torsion spring is sleeved on the outside of the second shaft, and the two ends of the torsion spring are fixedly connected to the second shaft and the second bracket, respectively.
[0017] Through the above technical solution, the function of the reset mechanism is to ensure that the screen can automatically return to its initial position. When the operator pulls rod two, causing the fixing block to embed into the fixing hole, the screen rotates accordingly, compressing the torsion spring in the process and storing energy. Once the locking between the fixing block and the fixing hole is released by pulling the L-shaped rod, the torsion spring releases its stored energy, driving the screen to automatically reset. In addition, due to the cleverly designed damping between shaft two and the second bracket, the screen can maintain a slow speed during the reset rotation, minimizing disturbance to the sediment at the bottom of the tank. This design is not only convenient and quick, but also practical and efficient.
[0018] The present invention is further configured such that: the shielding mechanism includes a third bracket fixedly connected to the rear end of the screen, a motor is installed in the third bracket, the output end of the motor is fixedly connected to a shaft three that is rotatably connected to the screen, a circular block is fixedly connected to the outside of the shaft three, and a plurality of baffles arranged in a circular array are fixedly connected to the outside of the circular block.
[0019] The main function of the shielding mechanism, as described above, is to shield the holes in the screen, effectively isolating the sediment from the supernatant. The operation is as follows: when the electric push rod moves the screen downwards, the motor synchronously drives the screen to continue moving downwards; when the screen approaches the sediment, the motor is started via program control (this part involves software control and is existing technology). After the motor starts, it drives the shaft to rotate, which in turn drives the circular block and the connected stop block to rotate together; as the stop block moves to a position directly below the holes in the screen, the holes are completely blocked. At this point, the screen successfully separates the sediment from the supernatant, facilitating the discharge of the supernatant while ensuring that the sediment is not carried out. This design is convenient, quick, simple, and practical.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This utility model ensures that the sediment can settle naturally by maintaining the initial vertical position of the screen, avoiding interference. When it is necessary to discharge the supernatant, the screen can be turned from vertical to horizontal by a pulling mechanism and fixed in position by a positioning mechanism. The slow drive of the electric push rod makes the screen descend smoothly, reducing disturbance to the water flow and sediment. When the screen descends above the sediment, the holes are covered by a blocking mechanism to isolate the sediment from the supernatant, ensuring that the supernatant is discharged smoothly and effectively preventing the sediment from being discharged with the supernatant.
[0022] 2. This utility model uses a reset mechanism to enable the screen to automatically return to its initial position after the liquid is drained, making the operation simple and efficient. The entire process achieves effective separation of precipitate and supernatant, reduces manual intervention, improves separation efficiency, and reduces the interference of equipment operation on precipitate, thus having high practicality and reliability.

Detailed Implementation
[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0033] Please see Figures 1-8This embodiment of a static sedimentation separation tank includes a tank body 1. A screen 2 is rotatably connected inside the tank body 1. A sliding rod 3 is rotatably connected to the center of the front end of the screen 2. A pulling mechanism 4 located at the front end of the sliding rod 3 is rotatably connected to the center of the front end of the screen 2. The pulling mechanism 4 includes a first bracket 401 fixedly connected to the center of the front end of the screen 2. A second rod 402 rotatably connected to the first bracket 401 and sliding inside a sleeve 5 is located at the front end of the sliding rod 3. An electric push rod 403 is installed on the inner top of the tank body 1. The output end of the electric push rod 403 is fixedly connected to the top of the sliding rod 3. Next, a protective cover 404 is fixedly connected to the top of the inner part of the tank 1 and slidably connected to the sleeve 5. The electric push rod 403 is located inside the protective cover 404. The function of the pulling mechanism 4 is to drive the screen 2 to rotate from an initial state perpendicular to the ground to a position parallel to the ground inside the tank 1. Initially, the screen 2 is perpendicular to the ground to ensure that the sediment can settle naturally without disturbance. When it is necessary to discharge the supernatant, in order to prevent the bottom sediment from being discharged upwards, the operator pulls the second rod 402 to raise it. Since the position of the sliding rod 3 is relatively fixed, this action causes the first support 401 to deflect, thereby driving the screen 2 from the position of the sleeve 5 to the position of the sleeve 5. The screen 2 is rotated from vertical to horizontal. Then, the relative positions of the sliding rod 3 and rod 402 are locked by the engagement of the fixing block 602 and the fixing hole 605. Next, the electric push rod 403 is activated via program control. This part involves software control and is existing technology. The electric push rod 403 operates, driving the sliding rod 3 to descend slowly, while simultaneously causing the sleeve 5 to slide within the protective cover 404. The protective cover 404 not only provides guidance for the sleeve 5 but also protects the electric push rod 403 from damage. As the electric push rod 403 slowly advances, the horizontally positioned screen 2 also gradually descends. The holes 12 on the screen 2 and... The slow movement of the electric push rod 403 effectively reduces the interference of the screen 2 on the water flow and the sediment at the bottom of the tank. Until the screen 2 moves above the sediment, the rotating baffle covers the holes 12 of the screen 2. At this time, the screen 2 acts as a barrier, isolating the sediment from the supernatant and reducing the disturbance of the water flow to the sediment during drainage. When you want the screen 2 to reset, the electric push rod 403 drives the sliding rod 3 to move upward, which in turn drives the screen 2 upward. By unlocking the fixing block 602 and the fixing hole 605, the screen 2 can rotate and reset to its initial position, ready for the next operation. The whole process is simple, practical and efficient.
[0034] like Figures 2-5As shown, a sleeve 5 is fixedly connected to the outside of the sliding rod 3, and a positioning mechanism 6 is slidably connected inside the sleeve 5. The positioning mechanism 6 includes a cylinder 601 fixedly connected inside the rod 402. A fixed block 602 with an inclined rear end is slidably connected inside the cylinder 601. The rear end of the fixed block 602 contacts and abuts against the sliding rod 3. An L-shaped rod 603 is fixedly connected to the front end of the fixed block 602. A spring 604 is sleeved on the outside of the L-shaped rod 603 between the front end of the fixed block 602 and the cylinder 601. The two ends of the spring 604 are fixedly connected to the fixed block 602 and the cylinder 601, respectively. A fixing hole 605 corresponding to the fixed block 602 is opened at the front end of the sliding rod 3. The main function of the positioning mechanism 6 is to stabilize the relative position between the rod 402 and the sliding rod 3. When the operator pulls the rod 402 upward, the cylinder 601 connected to it and the fixed block 603 inside it are fixedly connected. 2. Synchronous ascent; during this process, the fixing block 602 is pressed between the sliding rod 3 and the second cylinder 601, while the spring 604 is compressed; until the fixing block 602 is aligned with the fixing hole 605, with the restoring force of the spring 604, the fixing block 602 pops out and embeds into the fixing hole 605, thus firmly locking the relative position of the sliding rod 3 and the second rod 402; if this locking state needs to be released, simply pull the L-shaped rod 603 to make the fixing block 602 disengage from the fixing hole 605, and it can be easily unlocked; the advantage of the operator manually operating the second rod 402 is that they can flexibly control the rotation speed of the screen 2 as needed, avoiding too fast or too slow, and ensuring the accuracy of the operation; at the same time, manual operation also allows the operator to observe the internal condition of the tank 1 while rotating the screen 2, and promptly discover and solve problems; this operation method is convenient and quick, and is highly practical.
[0035] like Figures 3-5 As shown, the front end of the sleeve 5 is provided with a second groove 606, and the bottom of the front end of the protective cover 404 is provided with a third groove 607. The second groove 606 is designed to accommodate the second cylinder 601 and allow the second cylinder 601 to slide smoothly inside the sleeve 5; while the third groove 607 plays a supporting and guiding role, ensuring that the second cylinder 601 can slide smoothly inside the protective cover 404.
[0036] like Figures 4-5As shown, a reset mechanism 7 is fixedly connected to the bottom end of the sliding rod 3. The reset mechanism 7 includes a second bracket 701 fixedly connected to the center of the front end of the screen 2. A shaft 702 fixedly connected to the bottom of the sliding rod 3 is rotatably connected inside the second bracket 701. A torsion spring 703 is sleeved on the outside of the shaft 702. The two ends of the torsion spring 703 are fixedly connected to the shaft 702 and the second bracket 701, respectively. The function of the reset mechanism 7 is to ensure that the screen 2 can automatically return to its initial position. When the operator pulls the second rod 402, the fixing block 602 is driven into the fixing hole 6. At 05, the screen 2 rotates accordingly, compressing the torsion spring 703 in the process to store energy. Once the locking between the fixing block 602 and the fixing hole 605 is released by pulling the L-shaped rod 603, the torsion spring 703 releases its stored energy, driving the screen 2 to automatically reset. In addition, due to the cleverly designed damping between the shaft 2 702 and the second bracket 701, the screen 2 can maintain a slow speed during the reset rotation, minimizing disturbance to the sediment at the bottom of the tank 1. This design is not only convenient and quick, but also practical and efficient.
[0037] like Figures 7-8 As shown, a blocking mechanism 8 is fixedly connected to the rear end of the screen 2. The blocking mechanism 8 includes a third bracket 801 fixedly connected to the rear end of the screen 2. A motor 802 is installed inside the third bracket 801. The output end of the motor 802 is fixedly connected to a shaft 803 that is rotatably connected to the screen 2. A circular block 804 is fixedly connected to the outside of the shaft 803. Multiple baffles arranged in a circular array are fixedly connected to the outside of the circular block 804. The main function of the blocking mechanism 8 is to block the holes 12 on the screen 2, effectively isolating the sediment from the supernatant. The operation process is as follows: When the electric push rod 403 pushes the screen 2 downward, Motor 802 synchronously drives screen 2 to continue moving downwards; when screen 2 approaches the sediment, motor 802 is started by program control. This part involves software control and is existing technology. After motor 802 starts, it drives shaft 803 to rotate, which in turn drives the circular block 804 and the stop block 805 connected to it to rotate together; as the stop block 805 moves to the position directly below the hole 12 on screen 2, the hole 12 is completely blocked. At this time, screen 2 successfully separates the sediment from the supernatant, which facilitates the discharge of the supernatant and ensures that the sediment is not carried out. This design is convenient, quick, simple and practical.
[0038] like Figures 1-8As shown, the top of the tank 1 is fixedly connected to the feed inlet 9, the front end of the tank 1 is fixedly connected to the drain outlet 10, and the bottom of the tank 1 is fixedly connected to the discharge outlet 11. The screen 2 has multiple holes 12 arranged in a circular array. The design of the feed inlet 9 facilitates the injection of the liquid to be settled into the tank 1. The drain outlet 10 is used to smoothly discharge the supernatant, while the discharge outlet 11 is specifically used to discharge the sediment deposited at the bottom of the tank 1. In addition, the holes 12 are designed to reduce the interference of the screen 2 on the water flow when it rotates in the tank 1, so as to avoid affecting the sediment at the bottom of the tank 1.
[0039] In use, the screen 2 is initially perpendicular to the ground, ensuring that the sediment settles naturally. When it is necessary to discharge the supernatant, the screen 2 is turned from vertical to horizontal by pulling the lever 402, and the position is fixed by the fixing block 602 and the fixing hole 605. Then, the electric push rod 403 is activated to drive the screen 2 to descend slowly, reducing interference with the water flow and sediment. When the screen 2 descends above the sediment, the baffle covers the holes 12 of the screen 2, isolating the sediment from the supernatant, facilitating the discharge of the supernatant. After the discharge is completed, the screen 2 is raised by the electric push rod 403, and the fixing block 602 and the fixing hole 605 are unlocked by pulling the L-shaped rod 603. The screen 2 is automatically reset to the initial position by the torsion spring 703, waiting for the next operation. The whole process is simple to operate, practical and efficient, ensuring the effective separation of sediment and supernatant.
