Description

Technical Field

[0001] This utility model belongs to the field of edible oil processing technology, specifically a tank cleaning device for edible oil processing. Background Technology

[0002] In edible oil processing, the tank is the core equipment for oil refining, transfer and storage. Its internal cleanliness directly affects the safety of the oil and must meet the requirements for regular cleaning to prevent residual oil from oxidizing and breeding microorganisms, which could lead to safety problems. Currently, processing tanks generally adopt a small-mouth design for the top feed inlet and cleaning outlet in order to balance sealing and pollution prevention. Although this meets production needs, it brings challenges to cleaning. Existing methods such as manual wiping and high-pressure water gun washing have obvious drawbacks due to the small-mouth limitation: tools cannot flexibly reach into the tank, and cleaning blind spots are formed at the bottom corners, inner walls and pipe connections; operation requires repeated disassembly and reassembly of tank seals, resulting in low efficiency of tank cleaning per cycle; and the small-mouth design makes it difficult to visually observe the cleaning effect inside the tank, relying only on experience to judge, which easily leaves behind the potential for impurities. In summary, existing solutions cannot adapt to the structural characteristics of small-mouthed tanks and are unable to solve cleaning pain points. There is an urgent need for a dedicated cleaning device that is compatible with small openings, can eliminate cleaning blind spots, and is efficient and convenient, in order to meet food hygiene standards and the needs of edible oil processing and production. Utility Model Content

[0003] To address the problems existing in the background technology, this utility model provides a tank cleaning device for edible oil processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a tank cleaning device for edible oil processing, comprising a vehicle body, four locking wheels, a hydraulic cylinder, a cross plate, a motor, a rotating rod, a water spraying mechanism, and two cleaning mechanisms; The lower end of the vehicle body is provided with four locking wheels. The upper end of the vehicle body is fixedly connected to the cylinder body of the hydraulic cylinder. The telescopic end of the hydraulic cylinder is fixedly connected to one end of the horizontal plate. The other end of the horizontal plate is fixedly connected to the motor. The output shaft of the motor is fixedly connected to the rotating rod. The side wall of the rotating rod is provided with two cleaning mechanisms. The two cleaning mechanisms are symmetrically arranged. The lower end of the horizontal plate is provided with a water spraying mechanism. The water spraying mechanism is placed on the vehicle body.

[0005] The water spraying mechanism includes a ring pipe, multiple spray pipes, a corrugated pipe, a high-pressure water pump, and a water tank. The annular tube is movably mounted on the rotating rod. The upper end of the annular tube is fixedly connected to the horizontal plate. Multiple spray pipes are evenly distributed around the lower end of the annular tube. The nozzle of each spray pipe is set outward. One end of the annular tube is connected to the corrugated pipe. The other end of the corrugated pipe is connected to the outlet of the high-pressure water pump. The high-pressure water pump is installed in the water tank, and the water tank is placed on the vehicle body.

[0006] Each of the cleaning mechanisms includes a movable rod 1, a brush strip 1, a slider 1, a connecting rod 1, a movable rod 2, a brush strip 2, a slider 2, a connecting rod 2, and a brush strip 3; One end of the movable rod is connected to the side wall of the rotating rod via a torsion spring, and the other end of the movable rod is connected to the brush strip 1 via a torsion spring. A groove 1 is provided at the lower end of the movable rod, and the groove 1 is slidably connected to the slider 1. The slider 1 is hinged to one end of the connecting rod 1, and the other end of the connecting rod 1 is hinged to the movable rod 2. One end of the movable rod 2 is connected to the side wall of the rotating rod via a torsion spring, and the other end of the movable rod 2 is connected to the brush strip 2 via a torsion spring. A groove 2 is provided at the lower end of the movable rod 2, and the groove 2 is slidably connected to the slider 2. The slider 2 is hinged to one end of the connecting rod 2, and the other end of the connecting rod 2 is hinged to the upper end of the brush strip 3. One end of the brush strip 3 is hinged to the side wall of the rotating rod.

[0007] Compared with the prior art, the beneficial effects of this utility model are: 1. Adapts to small-mouth structure, solving the "difficult to enter and exit" problem: The cleaning mechanism naturally retracts when not in use, and its compact size allows it to easily enter or exit through the small-mouth inlet of the tank without disassembling the tank seals. This solves the problem of tools not being able to flexibly reach into the tank, and avoids the efficiency loss caused by repeated disassembly and reassembly of seals in traditional operations. The structure is precisely adapted to the design characteristics of small-mouth tanks.

[0008] 2. Automatic fit inside the can, eliminating blind spots: After being inserted into the can, brush strip three is pushed by the reaction force of the bottom of the can, and automatically opens through the connecting rod and movable rod one and movable rod two. With the pre-tightening force generated by the torsion spring, brush strip one and brush strip two can fit tightly against the inner wall of the can (including the corner area where the inner wall connects to the connecting pipe), and brush strip three fits completely against the bottom of the can, thoroughly solving the problem of blind spots that are difficult to cover by traditional cleaning methods.

[0009] 3. Mechanical + Water Spray Synergy for Enhanced Cleaning Efficiency: A motor-driven cleaning mechanism rotates and scrubs at high speed, while high-pressure water is precisely sprayed onto the cleaning area through a ring-shaped spray pipe. This softens stubborn grease and removes dirt and residue from the brushes, preventing secondary adhesion. Compared to manual wiping, cleaning efficiency is significantly improved, reducing the time required for a single tank cleaning session.

[0010] 4. Simple operation, reducing the manual threshold: This device achieves flexible movement and stable positioning through the lower locking wheel, and the hydraulic cylinder precisely controls the lifting and lowering of the cleaning components; the unfolding and resetting of the cleaning mechanism is fully automated, without the need for manual adjustment of the brush angle or length; the cleaning effect can be intuitively judged by observing the water quality discharged from the tank outlet, which can solve the problem of "difficult to intuitively observe the effect and easy to leave impurities" in traditional methods. Even novices can quickly master it, reducing technical dependence.

[0011] 5. Ensure oil safety and meet requirements: Thorough cleaning effectively prevents residual oil oxidation and microbial growth, eliminating potential oil contamination risks at the source; at the same time, the overall cleaning process and effectiveness assessment methods fully meet the requirements for regular tank cleaning, providing a reliable guarantee for the hygiene and safety of edible oil processing.

[0012] In summary, this utility model addresses the core pain points of cleaning small-mouthed cans, namely, "difficulty in reaching deep areas with tools, difficulty in clearing blind spots, low efficiency, and difficulty in judging the results." Through a design of "retractable cleaning mechanism + automatic fitting linkage + mechanical and water spray coordination," it not only solves the problems of traditional tools being "unable to reach, incompletely clean, inefficient, and inaccurate in judging the results," but also takes into account ease of operation and safety compliance. It can significantly improve the cleaning efficiency and quality of small-mouthed cans, while reducing labor costs and equipment maintenance costs, providing an efficient and feasible solution for edible oil processing enterprises to meet food safety standards and ensure production continuity.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0015] This embodiment describes a tank cleaning device for edible oil processing, including a vehicle body 1, four locking wheels 2, a hydraulic cylinder 3, a cross plate 4, a motor 5, a rotating rod 6, a water spraying mechanism, and two cleaning mechanisms. The lower end of the vehicle body 1 is provided with four locking wheels 2. The upper end of the vehicle body 1 is fixedly connected to the cylinder body of the hydraulic cylinder 3.

The water spraying mechanism is placed on the vehicle body 1.

[0016] The water spraying mechanism includes an annular pipe 7, multiple spray pipes 8, corrugated pipes 9, a high-pressure water pump 10, and a water tank 11; The annular pipe 7 is movably mounted on the rotating rod 6. The upper end of the annular pipe 7 is fixedly connected to the horizontal plate 4. Multiple spray pipes 8 are evenly distributed around the lower end of the annular pipe 7. The nozzle of each spray pipe 8 is set outward. One end of the annular pipe 7 is connected to the corrugated pipe 9. The other end of the corrugated pipe 9 is connected to the water outlet of the high-pressure water pump 10. The high-pressure water pump 10 is installed in the water tank 11. The water tank 11 is placed on the vehicle body 1.

[0017] Each of the cleaning mechanisms includes a movable rod 12, a brush strip 13, a slider 14, a connecting rod 15, a movable rod 2 16, a brush strip 2 17, a slider 2 18, a connecting rod 2 19, and a brush strip 3 20. One end of the movable rod 12 is connected to the side wall of the rotating rod 6 via a torsion spring, and the other end of the movable rod 12 is connected to the brush strip 13 via a torsion spring. The lower end of the movable rod 12 is provided with a sliding groove 1, which is slidably connected to the slider 14. The slider 14 is hinged to one end of the connecting rod 15, and the other end of the connecting rod 15 is hinged to the movable rod 16. One end of the movable rod 16 is connected to the side wall of the rotating rod 6 via a torsion spring, and the other end of the movable rod 16 is connected to the brush strip 17 via a torsion spring. The lower end of the movable rod 16 is provided with a sliding groove 2, which is slidably connected to the slider 18. The slider 18 is hinged to one end of the connecting rod 19, and the other end of the connecting rod 19 is hinged to the upper end of the brush strip 20. One end of the brush strip 20 is hinged to the side wall of the rotating rod 6.

[0018] The specific workflow of this utility model is as follows: First, pre-cleaning preparation and positioning are carried out. Sufficient cleaning water is injected into the water tank 11 to ensure that the high-pressure water pump 10, fixed to the bottom surface inside the water tank 11 (to prevent displacement during operation), can stably draw water. Then, the vehicle body 1 is pushed, and the four locking wheels 2 at the lower end enable flexible movement, transferring the device to the side of the tank to be cleaned. Subsequently, the hydraulic cylinder 3 is driven by an external hydraulic source, causing the extension end of the hydraulic cylinder to lift the horizontal plate 4 upwards (to prevent the rotating rod, cleaning mechanism, and tank inlet from colliding). Fine-tune the vehicle's position to align the axis of the rotating rod 6 with the center of the tank's inlet. Finally, lock the four locking wheels 2 to secure the vehicle and prevent displacement during cleaning. After positioning, activate the hydraulic cylinder 3 to extend and retract in the reverse direction, causing the horizontal plate 4, motor 5, rotating rod 6, and water spray mechanism (annular pipe 7 fixed to the lower end of the horizontal plate, moving down synchronously with the horizontal plate, and its movable sleeve design avoids interference with the rotation of the rotating rod) to slowly descend. This allows the rotating rod 6, the two cleaning mechanisms, and the spray pipe 8 to gradually extend into the tank. When not in contact with the tank wall, the movable rods naturally retract. When the lower end of the cleaning mechanism's brush strip 20 contacts the bottom of the tank, the bottom of the tank generates an upward reaction force, pushing the brush strip 20 to rotate upward around its hinge point with the rotating rod 6. The brush strip 20, through the connecting rod 19, drives the slider 18 to slide upward within the groove 2 of the movable rod 16, thereby pushing the movable rod 16 to open outward around its torsion spring connection point with the rotating rod 6. Simultaneously, the movable rod 16, through the connecting rod 15, drives the slider 14 to move within the groove 12 of the movable rod 1. The slide bar slides upwards, pushing the movable rod 12 to open outwards synchronously around its torsion spring connection point with the rotating rod 6. During this process, the torsion springs connecting the movable rod 12, the movable rod 2 16, and the brush strips 13 and 2 17 all generate pre-tension force, ensuring that the brush strips 13 and 2 17 are tightly attached to the inner wall of the tank, and the brush strip 3 20 is tightly attached to the bottom of the tank, achieving precise attachment to the tank without manual adjustment (the length of each movable rod and the spring force of the torsion spring of the cleaning mechanism are preset according to the size of the specific tank to be cleaned).First, motor 5 is started. The output shaft of motor 5 drives the rotating rod 6 to rotate at high speed. The rotating rod 6 simultaneously drives two symmetrically arranged cleaning mechanisms to rotate. The first and second brush strips 13 and 17 of the cleaning mechanism rotate and scrub the inner wall of the tank, while the third brush strip 20 rotates and scrubs the bottom of the tank, effectively removing residual cooking oil stains from the tank wall and bottom. At the same time, the high-pressure water pump 10 is started. The cleaning water in the water tank 11 is pressurized by the high-pressure water pump 10 and then transported to the annular pipe 7 through the corrugated pipe 9, which can move up and down with the horizontal plate 4 (to avoid the water pipe from being pulled and broken). The annular pipe 7 sprays high-pressure water evenly onto the inner wall and bottom of the tank through multiple spray pipes 8 (with nozzles facing outward) evenly distributed around the circumference. This softens and rinses the dirt and removes the dirt residue generated by the brush scrubbing in time, preventing secondary adhesion and greatly improving cleaning efficiency. Keep motor 5 and high-pressure water pump 10 running until there is no obvious residual dirt on the inner wall and bottom of the tank (the degree of cleanliness can be judged by observing the water quality discharged from the tank outlet); after cleaning, enter the reset and drainage stage. First, turn off the high-pressure water pump 10 to stop spraying water, then start the hydraulic cylinder 3 to drive the horizontal plate 4, rotating rod 6, and cleaning mechanism to lift upward. As the rotating rod 6 rises, the cleaning mechanism disengages from the tank wall and bottom, and each movable rod (movable rod one 12, movable rod two 16) and each brush strip (brush strip one 13, brush strip two 17, brush strip three 20) resets under the rebound force of the torsion spring (each movable rod retracts inward, and each brush strip returns to its initial angle), the overall volume shrinks, and it can easily exit from the tank inlet, avoiding collision with the inlet. Finally, the cleaning wastewater in the tank is completely discharged through the outlet, completing the entire cleaning process.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
