[0002] Storage tanks are containers used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. They are made of various materials such as metal, plastic, and ceramic, and their overall structure is quite similar. They are usually tank-shaped and equipped with a sealing cover, inlet, outlet, and drain.

[0003] Most storage tanks on the market are similar in overall structure. When storing materials with high viscosity or that are prone to sedimentation, the selected tanks are usually equipped with a scraper assembly. The scraper is driven by a motor to rotate at a constant speed, which can scrape off the sediment at the bottom of the tank, making it easier to discharge it from the drain outlet. However, there are some functional shortcomings in actual use, such as the fixed height of the scraper, which usually can only scrape the bottom or the side wall at a fixed height. The working range is also limited, as it does not have the function of adjusting the working range by raising or lowering.

[0004] Now, a novel storage tank with a lifting sediment scraping mechanism is proposed to solve the above problems. Utility Model Content

A fixed frame is fixedly connected between the splined cylinder and the side scrapers. A lower scraper is fixedly connected to the bottom end of the fixed frame. A lower rubber strip is fixedly connected to the bottom end of the lower scraper. Side rubber strips are disposed on the outer side of the side scrapers.

[0008] As a further technical solution of this utility model, the output end of the geared motor is fixedly connected to the top end of the spline shaft, the external shape and size of the spline shaft are adapted to the internal shape and size of the spline cylinder, the spline shaft passes through the interior of the spline cylinder, and the spline cylinder can slide up and down along the outside of the spline shaft.

[0009] As a further technical solution of this utility model, the bottom end of the spline shaft is higher than the bottom end of the tank body, the output end of the electric cylinder is fixedly connected to the top end of the suspension frame, and the electric cylinder, the geared motor, and the PLC controller are electrically connected.

[0012] As a further technical solution of this utility model, an annular diverter pipe is fixedly connected to the bottom end of the suspension frame, and multiple sets of first high-pressure nozzles are fixedly connected to the outside of the annular diverter pipe. Multiple sets of second high-pressure nozzles are fixedly connected to the bottom end of the annular diverter pipe. An inlet is fixedly connected to the right side of the sealing cover.

[0014] (1) By setting up an electric cylinder, a geared motor, a splined shaft, a suspension frame, a fixed cylinder, a bearing, a splined cylinder, a fixed frame, a lower scraper, a lower rubber strip, a side scraper, and a side rubber strip, when in use, the tank body and the sealing cover constitute the basic main body of the storage tank. Valves are installed at the filling port, the discharge port, and the sewage discharge port for sealing. When it is necessary to scrape the sediment on the inner wall and bottom of the tank, the geared motor drives the splined cylinder to rotate at a constant speed through the splined shaft. The fixed cylinder in the suspension frame stabilizes the splined cylinder through the bearing. The lower scraper and the side scraper on the fixed frame outside the splined cylinder rotate at a constant speed. The side rubber strip on the side scraper adheres to the inner wall of the tank. When it is necessary to adjust the cleaning height, the geared motor stops running, and then the electric cylinder extends or retracts, which can drive the suspension frame to move up and down. The splined cylinder slides up and down synchronously along the outside of the splined shaft. When the electric cylinder extends to the maximum, that is, the lower rubber strip at the bottom of the lower scraper adheres to the bottom of the tank, the sediment at the bottom can be scraped off, thus expanding the working range and realizing the function of adjusting the working range by lifting.

[0015] (2) By setting up a side scraper, side rubber strip, movable groove, traction block, first magnetic strip, second magnetic strip and electromagnet, during the scraping of the side, the first magnetic strip and the second magnetic strip have the same magnetic pole, pushing the traction block and the side rubber strip towards the inner wall of the tank. There is a certain buffer zone during the scraping process. When the electromagnet is energized, it generates magnetism and attracts the first magnetic strip from the outside, which increases the adhesion between the side rubber strip and the tank, and also increases the scraping force at the same time, realizing the function of adjustable scraping force of the inner wall;

[0016] (3) By setting up an inlet, spring tube, annular diversion pipe, first high-pressure nozzle and second high-pressure nozzle, when in use, rinsing can be carried out at the same time as scraping. The high-pressure cleaning fluid is pumped into the annular diversion pipe along the inlet and spring tube.

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.

[0023] Example: Please refer to Figure 1-4 A storage tank with a lifting sediment scraping mechanism includes a tank body 1, a pressure gauge 2 fixedly installed at the front end of the tank body 1, a filling port 3 provided at the top left side of the tank body 1, a sealing cover 4 connected to the top flange of the tank body 1, a PLC controller 22 fixedly installed on the right side of the tank body 1, a discharge port 28 provided at the bottom right side of the tank body 1, a drain port 29 fixedly connected to the bottom end of the tank body 1, and a cleaning component for easy adjustment of the scraping height inside the tank body 1.

[0024] Please see Figure 1-4 A storage tank with a lifting sediment scraping mechanism also includes a cleaning assembly. The cleaning assembly includes a suspension frame 8, which is disposed inside the tank body 1. A fixed cylinder 9 is fixedly connected to the middle position inside the suspension frame 8. A splined cylinder 11 is disposed at the middle position inside the fixed cylinder 9. A bearing 10 is installed between the fixed cylinder 9 and the splined cylinder 11. Electric cylinders 5 are fixedly installed on both sides of the top of the sealing cover 4. A reduction motor 6 is fixedly installed at the middle position of the top of the sealing cover 4. A splined shaft 7 is movably connected to the middle position of the top of the sealing cover 4. Side scrapers 15 are disposed on the left and right sides of the splined cylinder 11. A fixed frame 12 is fixedly connected between the splined cylinder 11 and the side scrapers 15. A lower scraper 13 is fixedly connected to the bottom end of the fixed frame 12. A lower rubber strip 14 is fixedly connected to the bottom end of the lower scraper 13. A side rubber strip 16 is disposed on the outer side of the side scraper 15.

[0025] The output end of the geared motor 6 is fixedly connected to the top end of the spline shaft 7. The external shape and size of the spline shaft 7 are adapted to the internal shape and size of the spline cylinder 11. The spline shaft 7 passes through the interior of the spline cylinder 11. The spline cylinder 11 can slide up and down along the outside of the spline shaft 7. The bottom end of the spline shaft 7 is higher than the bottom end of the tank 1. The output end of the electric cylinder 5 is fixedly connected to the top end of the suspension frame 8. The electric cylinder 5, the geared motor 6, and the PLC controller 22 are electrically connected. The lower scraper 13 and the side scraper 15 are symmetrically distributed about the vertical center line of the spline cylinder 11. The lower rubber strip 14 and the side rubber strip 16 are elastic, which makes it easy to adjust the scraping working range.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the geared motor 6 drives the splined cylinder 11 to rotate at a constant speed through the splined shaft 7. The fixed cylinder 9 inside the suspension frame 8 stabilizes the splined cylinder 11 through the bearing 10. The lower scraper 13 and the side scraper 15 on the external fixed frame 12 of the splined cylinder 11 rotate at a constant speed. The side rubber strip 16 on the side scraper 15 adheres to the inner wall of the tank body 1. When it is necessary to adjust the cleaning height, the geared motor 6 stops running, and then the electric cylinder 5 extends or retracts, which can drive the suspension frame 8 to move up and down. The splined cylinder 11 slides up and down synchronously along the outside of the splined shaft 7. When the electric cylinder 5 extends to its maximum, that is, the lower rubber strip 14 at the bottom of the lower scraper 13 adheres to the bottom of the tank body 1, the bottom sediment can be scraped off, thus expanding the working range.

[0027] The side scraper 15 has an internal movable groove 17. A second magnetic strip 20 is fixedly installed on the inner wall of the movable groove 17. A traction block 18 is provided inside the movable groove 17. A first magnetic strip 19 is fixedly connected to the side of the traction block 18 near the second magnetic strip 20. An electromagnet 21 is fixedly connected to the bottom of the tank body 1. The side rubber strip 16 and the traction block 18 are fixedly connected. The shape and size of the outer part of the first magnetic strip 19 are adapted to the shape and size of the inner part of the movable groove 17. The first magnetic strip 19 can slide left and right along the inside of the movable groove 17. The magnetic poles of the opposite sides of the first magnetic strip 19 and the second magnetic strip 20 are the same. The electromagnet 21 and the PLC controller 22 are electrically connected to facilitate the adjustment of the scraping force on the inner wall.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the first magnetic strip 19 and the second magnetic strip 20 have the same magnetic poles. The traction block 18 and the side rubber strip 16 are pushed towards the inner wall of the tank 1. During the scraping process, there is a certain buffer zone. The electromagnet 21 is energized and generates magnetism, attracting the first magnetic strip 19 from the outside, which increases the adhesion between the side rubber strip 16 and the tank 1, and thus simultaneously increases the scraping force.

[0029] The bottom end of the suspension frame 8 is fixedly connected to an annular diverter pipe 25. Multiple sets of first high-pressure nozzles 26 are fixedly connected to the outside of the annular diverter pipe 25. Multiple sets of second high-pressure nozzles 27 are fixedly connected to the bottom end of the annular diverter pipe 25. The right side of the sealing cover 4 is fixedly connected to a liquid inlet 23. A spring tube 24 is movably connected between the liquid inlet 23 and the annular diverter pipe 25. The vertical center lines of the suspension frame 8 and the annular diverter pipe 25 coincide. The liquid inlet 23, the spring tube 24, and the annular diverter pipe 25 are internally connected to facilitate internal rinsing.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, high-pressure cleaning fluid is pumped into the annular diverter pipe 25 through the inlet 23 and spring tube 24. The first high-pressure nozzle 26 and the second high-pressure nozzle 27 on the annular diverter pipe 25 spray high-pressure fan-shaped water jets to the outside and bottom respectively to rinse the inner wall and bottom of the tank 1.

[0031] Working Principle: In use, the tank body 1 and the sealing cover 4 form the basic structure of the storage tank. Valves are installed at the filling port 3, the discharge port 28, and the sewage discharge port 29 for sealing. When it is necessary to scrape off the sediment on the inner wall and bottom of the tank body 1, the reduction motor 6 drives the splined cylinder 11 to rotate at a constant speed through the splined shaft 7. The fixed cylinder 9 inside the suspension frame 8 stabilizes the splined cylinder 11 through the bearing 10. The lower scraper 13 and the side scraper 15 on the external fixed frame 12 of the splined cylinder 11 rotate at a constant speed. The side rubber strip 16 on the side scraper 15 adheres to the inner wall of the tank body 1. When it is necessary to adjust the cleaning height, the reduction motor 6 stops running, and then the electric cylinder 5 extends or retracts, which can drive the suspension frame 8 to move up and down. The splined cylinder 11 slides up and down synchronously along the outside of the splined shaft 7. When the electric cylinder 5 extends to its maximum, that is, the lower rubber strip 14 at the bottom of the lower scraper 13 adheres to the bottom of the tank body 1, the sediment at the bottom can be scraped off, thus expanding the working range. During the scraping process, the first magnetic strip 19 and the second magnetic strip 20 have the same magnetic poles, pushing the traction block 18 and the side rubber strip 16 towards the inner wall of the tank 1. There is a buffer zone during the scraping process. When the electromagnet 21 is energized, it attracts the first magnetic strip 19 from the outside, increasing the adhesion between the side rubber strip 16 and the tank 1, thus simultaneously increasing the scraping force. Simultaneously, rinsing can be performed. High-pressure cleaning fluid is pumped into the annular diversion pipe 25 through the inlet 23 and the spring tube 24. The first high-pressure nozzle 26 and the second high-pressure nozzle 27 on the annular diversion pipe 25 spray high-pressure fan-shaped water jets outwards and to the bottom, respectively, rinsing the inner wall and bottom of the tank 1.
