Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment for plastic storage tanks, and in particular to a cleaning device for plastic storage tanks. Background Technology

[0002] Plastic storage tanks are widely used in industries such as manufacturing, agriculture, construction, food processing, chemicals, and pharmaceuticals. They are used to store liquids, solid particles, or powders. They are typically made of various plastic materials, such as polyethylene, polypropylene, polyvinyl chloride, and polycarbonate. Cleaning devices for plastic storage tanks are used for regular maintenance and cleaning of the tank interior to ensure the quality and safety of the stored substances.

[0003] As described in the cleaning device for plastic storage tanks disclosed in patent publication number CN214382854U, during operation, the user can spray water into the tank from one end while cleaning. Then, by setting guide rods, connecting seats, and springs, the device can fully contact the inner wall of the tank according to the different pipe diameters inside the tank, ensuring that there are no dead corners in the cleaning. Driven by a hydraulic cylinder, the device cleans from the front end of the tank to the rear end. The device has a second cleaning disc set on the inner side of the fixed frame and a first cleaning disc set on the edge of the fixed frame, which are installed in different directions. This allows for all-round automatic cleaning of the inner wall of the plastic storage tank, and can thoroughly remove dirt during operation.

[0004] However, when the above structure is in use, it cleans the inside of the tank through the No. 1 and No. 2 cleaning discs set at the front end. If the size of the tank is large, the spring adjustment alone cannot meet the needs. It is necessary to replace the guide rods of different lengths, the cleaning discs of different sizes, or the springs of different elasticity. This not only increases the cost of spare parts inventory, but also prolongs the equipment debugging time and affects the efficiency of automatic cleaning.

[0005] Therefore, it is necessary to provide a new cleaning device for plastic storage tanks to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a cleaning device for plastic storage tanks.

[0007] The present invention provides a cleaning device for plastic storage tanks, comprising a base, a support column, and a hydraulic cylinder. The support column is fixedly connected to the top of the base, and the hydraulic cylinder is fixedly connected to the end of the support column away from the base. A rotating component is fixedly connected to the telescopic end of the hydraulic cylinder, and a cleaning component for cleaning the plastic storage tank is fixedly connected to the end of the rotating component away from the hydraulic cylinder. The cleaning assembly includes a drive mechanism, a sleeve, a drive ring, and several movable plates. The drive mechanism is fixedly connected to the telescopic end of the rotating assembly away from the hydraulic cylinder. The sleeve is fitted onto the end of the drive mechanism away from the drive component, and several fixed plates are fixedly connected to the outer surface of the sleeve. The threaded rod of the drive ring is connected to the outer surface of the drive assembly, and a fixed ring is rotatably connected to the drive ring. A first hinge frame is hinged to the outer surface of the fixed ring through a fixed block. Two second hinge frames are hinged to the side walls of the several fixed plates. The bottoms of the several movable plates are all hinged to the first hinge frame and the two second hinge frames at the ends away from the fixed ring and the fixed plates. A cleaning sponge is fixedly connected to the ends of the several movable plates away from the fixed plates.

[0008] Preferably, the drive assembly includes a drive member and a threaded rod. The drive member is fixedly connected to the telescopic end of the rotating assembly away from the hydraulic cylinder, and the output end of the drive member is fixedly connected to one end of the threaded rod. The end of the threaded rod away from the drive member is rotatably connected to the inner wall of the sleeve.

[0009] Preferably, the rotating assembly includes a U-shaped frame and a drive motor. The U-shaped frame is fixedly connected to the telescopic end of the hydraulic cylinder, and a support block is fixedly connected to the end of the U-shaped frame away from the hydraulic cylinder. The drive motor is fixedly connected to the inner wall of the U-shaped frame, and a rotating rod is fixedly connected to the telescopic end of the drive motor. The rotating rod is rotatably connected to the inner wall of a through hole opened on the support block.

[0010] Preferably, the driving component is a servo motor, which is fixedly connected to the telescopic end of the rotating assembly away from the hydraulic cylinder, and the output end of the servo motor is fixedly connected to one end of the threaded rod.

[0011] Preferably, the end of the rotating rod away from the drive motor is fixedly connected to the end of the servo motor away from the threaded rod.

[0012] Preferably, a plurality of triangular stabilizing plates are fixedly connected to the top of the base, and the ends of the plurality of triangular stabilizing plates away from the base are fixedly connected to the periphery of the support column.

[0013] Compared with related technologies, the cleaning device for plastic storage tanks provided by this utility model has the following beneficial effects: When cleaning the plastic storage tank requires cleaning, the servo motor is activated first. This motor drives a threaded rod to rotate, which in turn rotates a drive ring and moves it closer to the sleeve. The drive ring then moves a fixed ring towards the sleeve. Simultaneously, the fixed ring, via a fixed block, rotates a first hinge frame. This rotation causes a movable plate to expand outwards, simultaneously rotating two second hinge frames. The movable plate and the cleaning sponge on it support the inner wall of the plastic storage tank. The drive motor then activates, rotating a rod to clean the inner wall of the plastic storage tank using the movable plate and cleaning sponge. This device reduces component inventory costs, shortens equipment setup time, and minimizes the impact on automatic cleaning efficiency. Attached Figure Description

The bottom of several movable plates 6 is hinged to the first hinge frame 9 and the two second hinge frames 10 away from the fixed ring 8 and the fixed plates 7, and a cleaning sponge 11 is fixedly connected to the end of several movable plates 6 away from the fixed plates 7. It should be noted that a number of triangular stabilizing plates 18 are fixedly connected to the top of the base 1, and the ends of the triangular stabilizing plates 18 away from the base 1 are fixedly connected to the periphery of the support column 2. The drive assembly includes a drive component and a threaded rod 12. The drive component is fixedly connected to the telescopic end of the rotating assembly away from the hydraulic cylinder 3, and the output end of the drive component is fixedly connected to one end of the threaded rod 12. The end of the threaded rod 12 away from the drive component is rotatably connected to the inner wall of the sleeve 4. It should be noted that the driving component is a servo motor 17. The servo motor 17 is fixedly connected to the telescopic end of the rotating assembly away from the hydraulic cylinder 3, and the output end of the servo motor 17 is fixedly connected to one end of the threaded rod 12.

[0019] The working principle of this utility model is as follows: When cleaning the plastic storage tank is required, the servo motor 17 is started first. At this time, the servo motor 17 drives the threaded rod 12 to rotate. While the threaded rod 12 is rotating, it drives the drive ring 5 set on it to rotate and move towards the sleeve 4. The drive ring 5 drives the fixed ring 8 set on it to move towards the sleeve 4. While the fixed ring 8 is moving, it drives the first hinge frame 9 to rotate through the fixed block set on it. When the first hinge frame 9 rotates, it drives the movable plate 6 to expand outward through the end away from the fixed block. While the movable plate 6 is expanding outward, it drives the two second hinge frames 10 to rotate. Thus, the inner wall of the plastic storage tank is supported by the movable plate 6 and the cleaning sponge 11 set on the movable plate 6. At this time, the drive motor 14 is started. The drive motor 14 drives the movable plate 6 and the cleaning sponge 11 to clean the inner wall of the plastic storage tank through the rotating rod 16.
