The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Currently, composite carbon sources are stored and transported through columnar storage tanks. After long-term storage, residual stains are likely to appear on the inner wall of the storage tank, including aqueous solution stains, organic solvents and grease stains, sediments, and viscous liquids, etc., which affect the quality of the carbon source. The traditional cleaning device for composite carbon source storage tanks uses a scraper to clean and remove stains. It can often only scrape off most of the prominent stains, and there will still be residues in the uneven areas of the inner wall of the storage tank, resulting in poor cleaning effect and being unable to be applicable to storage tanks of various sizes.

[0025] In view of this, the present invention proposes an automated cleaning device for composite carbon source storage tanks. Figures 1-4 For an embodiment of the automated cleaning device for composite carbon source storage tanks provided by the present invention, please refer to Figures 1-4 , the automated cleaning device 100 for composite carbon source storage tanks is installed on the base 1 of the storage tank, the driving mechanism 2 provided on the base 1, and the brush head assembly 3.

[0026] Specifically, for a vertical cylindrical storage tank with an opening at the top, the base 1 can be fixedly installed by connecting with bolts and an opening flange. The driving mechanism 2 includes a driving member 21, a first driving shaft 22 and a second driving shaft 23. The driving member 21 is a motor, which is located outside the storage tank and is drivingly connected to the first driving shaft 22. Both the first driving shaft 22 and the second driving shaft 23 extend into the storage tank. The first driving shaft 22 and the second driving shaft 23 are sleeved with each other, and their relative rotation is prevented by an embedded structure. The second driving shaft 23 can slide relative to the first driving shaft 22, and the motor can drive the first driving shaft 22 and the second driving shaft 23 to rotate coaxially. The brush head assembly 3 includes a first brush head 31, a second brush head 32, a connecting rod 33 and a support rod 34. One end of the connecting rod 33 is rotatably connected to the first brush head 31, and the other end is rotatably connected to the shaft body of the first driving shaft 22, so that the first brush head 31 is arranged on the side of the storage tank. One end of the support rod 34 is rotatably connected to the second driving shaft 23, and the other end is rotatably connected to the rod body of the connecting rod 33. The second brush head 32 is fixedly connected to the end of the second driving shaft 23. It should be noted that one end of the connecting rod 33 is rotatably connected to the middle part of the first brush head 31. In addition, in this embodiment, both the connecting rod 33 and the support rod 34 are connected to the brush head and the driving shaft by means of hinges.

[0027] In the technical solution of the present invention, by setting the first brush head 31 and the second brush head 32, the stains on the inner walls of the carbon source storage tank are comprehensively washed. And when the second brush head 32 at the end of the second driving shaft 23 contacts one inner wall, continue to press down to make the second driving shaft 23 retract into the first driving shaft 22. At the same time, the support rod 34 drives the connecting rod 33 to rotate, so that the first brush head 31 unfolds and gets closer to the other inner wall. This device can adapt to carbon source storage tanks of various sizes, realizing comprehensive and fast cleaning; and replacing manual labor with machinery, avoiding the harm of toxic substances in the tank to the cleaning personnel. Just fix the equipment on the storage tank, and the comprehensive cleaning of the stains in the storage tank can be realized automatically.

[0028] To effectively remove the oil stains on the inner wall of the storage tank, please refer to Figure 1 and 2 , in an embodiment of the present invention, it further includes a spraying mechanism 4 and a liquid storage tank 5 provided on the base 1. The spraying mechanism 4 is located inside the storage tank. The spraying mechanism 4 includes an annular spray head 41 provided on the outer periphery of the first driving shaft 22. The annular spray head 41 has a plurality of nozzles 411 communicating with the liquid storage tank 5. Each nozzle 411 is arranged towards the inner wall of the storage tank, so that the cleaning agent in the liquid storage tank 5 can be sprayed onto the inner wall of the storage tank.

[0029] Furthermore, to effectively spray the cleaning agent onto the inner wall of the storage tank, please refer to Figure 1 and 2, in an embodiment of the present invention, the spraying mechanism 4 further includes a water pump 42 for pumping the cleaning agent in the liquid storage tank 5 into the annular nozzle 41, thereby realizing spraying.

[0030] Furthermore, to enable the cleaning agent to be fully dispersed on the inner wall of the storage tank, please refer to Figures 1-3 , in an embodiment of the present invention, a vibration unit 412 is provided at the nozzle 411 for dispersing the cleaning agent conveyed by the liquid storage tank 5 to form a fine particle liquid mist, so that the cleaning agent can fall more evenly on the inner wall of the storage tank, and then can react fully with the substance to achieve thorough cleaning. Among them, the vibration unit 412 is a piezoelectric ceramic, which is cylindrical in shape and is installed in the nozzle 411 through a fixing rod. It should be noted that piezoelectric ceramics are a kind of ceramic material that can convert mechanical energy and electrical energy into each other - the piezoelectric effect, and each vibration unit 412 is electrically connected to an external power source and a controller.

[0031] To adapt to carbon source storage tanks of different specifications, please refer to Figure 1 and 2 , in an embodiment of the present invention, there are multiple first drive shafts 22 which are connected to each other. When the height of the storage tank is relatively high, the inner wall of the storage tank is cleaned by connecting multiple first drive shafts 22. In addition, in other embodiments, for some horizontal storage tanks, the device 100 can be entirely arranged inside the storage tank, and several connecting pieces are provided around the base 1, and the connecting pieces are driven by screws to abut against the inner wall of the storage tank to fix the base 1, and the cleaning of the horizontal storage tank can also be achieved.

[0032] In order to provide some tension when the brush head is scrubbing the inner wall of the storage tank, please refer to Figure 1 and 2 , in an embodiment of the present invention, it further includes a return spring 6. One end of the return spring 6 is fixedly connected to the first drive shaft 22, and the other end is fixedly connected to the second drive shaft 23. When the device 100 starts to work, the operator retracts the first brush head 31, and the return spring 6 is stretched. Then, the second brush head 32, the first brush head 31 together with the second drive shaft 23 and the first drive shaft 22 are extended into the tank through the opening of the storage tank; then the return spring 6 returns to its original state, and the first brush head 31 is unfolded again; the operator continues to press down the base 1 so that the first brush head 31 approaches the bottom wall of the storage tank, and the second drive shaft 23 starts to retract relative to the first drive shaft 22 until the first brush head 31 completely adheres to the side wall of the storage tank, and at the same time the return spring 6 is compressed; finally, the base 1 and the opening flange of the storage tank are fixedly connected. Since the return spring 6 is in a compressed state when the device 100 is working, it can force the first brush head 31 and the second brush head 32 to be closer to the inner wall of the storage tank, and the scrubbing effect is better.

[0033] Since the side wall area of the storage tank is relatively large, to clean the side wall of the storage tank more efficiently, please refer to Figure 1and 2 In an embodiment of the present invention, a plurality of first brush heads 31 are provided and are evenly distributed along the circumferential direction. In this embodiment, two first brush heads 31 are provided and are symmetrically arranged on both sides of the drive shaft.

[0034] To clean the adhered solid attachments, please refer to Figure 1 and 2 In an embodiment of the present invention, both the first brush head 31 and the second brush head 32 are brushes provided on the mounting plate 35. The middle of the mounting plate 35 of the first brush head 31 is hinged to the end of the connecting rod 33, and the mounting plate 35 of the second brush head 32 is fixedly connected to the end of the second drive shaft 23; and, a vibration motor is provided on the mounting plate 35. By means of high-frequency vibration, the brushes are frequently rubbed against the adhered solids on the inner wall of the storage tank, so that the solid attachments are shaken and broken and fall off. It should be understood that the vibration motor drives the eccentric wheel to rotate, causing the motor shaft to vibrate, thereby driving the brush head to vibrate.

[0035] To remove grease stains and viscous liquids, please refer to Figure 1 and 2 In an embodiment of the present invention, the first brush head 31 and the second brush head 32 further include a scraper 36. The scraper 36 is elastically mounted on the mounting plate 35 by a spring, so as to adapt to the uneven inner wall of the storage tank. The width of the scraper 36 is smaller than that of the brush, and it can effectively scrape off the grease stains and viscous liquids, which is beneficial for the brush to further clean other stains and prevent the brush from being attached by oil stains and viscous substances, resulting in a deteriorated washing effect.

[0036] Furthermore, in order to ensure the oil stain removal efficiency, in an embodiment of the present invention, the output shaft of the vibration motor 351 is connected to an eccentric block 352. The rotation axis of the eccentric block 352 is eccentrically arranged with respect to the axis of the vibration motor 351. By setting the eccentric block 352, the centroid of the eccentric block 352 deviates from the motor axis. When the motor drives it to rotate, the centrifugal force changes periodically, forming a radial alternating inertial force, which causes the mounting plate 35 and the bristles to generate high-frequency micro-amplitude vibrations, thereby deeply cleaning the oil stains on the inner wall and ensuring the oil stain removal efficiency.

[0037] Meanwhile, the scraping plate 36 is connected to the mounting plate 35 through an elastic component. The elastic component includes a guiding column 361 and a compression spring 362 sleeved on the guiding column 361. One end of the guiding column 361 is fixed to the mounting plate 35, and the other end penetrates through the scraping plate 36 and is limited by an adjusting nut 363. By setting the elastic component, when the scraping plate 36 collides with the inner wall of the storage tank, the spring can absorb the collision energy, reduce the load of the driving mechanism, thereby prolonging the service life of the motor and transmission components. At the same time, the scraping plate 36 and the guiding column 361 can be quickly disassembled and assembled through nuts, simplifying the replacement process and improving the replacement efficiency. At the same time, the compression spring 362 enables the scraping plate 36 to retract inward when it touches the convex part of the inner wall of the storage tank, thereby protecting the scraping plate 36 and prolonging the service life of the scraping plate 36.

[0038] In order to drive each electrical component, in an embodiment of the present invention, a power supply and a controller are further included. The controller is respectively connected to the driving member 21, the spraying mechanism 4, and the vibration motor in a controlled manner. When the device 100 starts to work, the controller controls the driving member 21 to start and drives the brush head to rotate. At the same time, the controller controls the water pump 42 to pump the cleaning agent, and starts the vibration unit 412 to disperse the cleaning agent. At the same time, the vibration motor is started. While the brush head is rotating, it frictionally contacts the inner wall of the storage tank at a high frequency. It should be understood that the vibration motor and the vibration unit 412 can be powered by an independent power supply to avoid external wires.

[0039] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
