Description

Technical Field

[0001] This utility model belongs to the field of steel drum cleaning technology, specifically relating to a steel drum inner wall cleaning device. Background Technology

[0002] Steel drums are cylindrical containers made of metal, widely used for packaging, transporting, and storing various goods, such as dangerous goods, pharmaceuticals, and food. Types of steel drums: Based on the structure and diameter of their closure, steel drums are divided into two main categories: closed-top steel drums and fully open-top steel drums. Open-top steel drums are further divided into four types: small-opening, medium-opening, straight-opening, and necked-opening. In addition, there are steel-plastic composite drums, steel carrying drums, etc. Uses of steel drums: Steel drums are widely used in industrial product packaging, transport packaging, and sales packaging, especially in situations requiring the storage and transportation of hazardous materials, chemicals, and food. Various methods exist for cleaning the inner wall of steel drums. The choice of method requires comprehensive consideration of factors such as the material of the steel drum, the type of dirt, cleaning requirements, and cost. After a steel drum contains liquid, its inner wall needs to be cleaned to prevent residual liquid from affecting subsequent use. If the liquid is viscous, residues may remain on the inner wall of the steel drum, requiring the use of cleaning tools for scrubbing, which is slow. Therefore, the inventor has proposed a steel drum inner wall cleaning device. Utility Model Content

[0028] This specific embodiment is a steel drum inner wall cleaning device, the structural diagram of which is shown below. Figure 1As shown, it includes a cleaning table 1, a cleaning mechanism 4, and a limiting block 2. Two oppositely distributed limiting blocks 2 are provided in front of the cleaning table 1. The opposite sides of the two sets of limiting blocks 2 are respectively connected to clamping cylinders 3. The clamping cylinders 3 are fixedly installed on the side wall of the cleaning table 1, and the telescopic end moves through the cleaning table 1 and is fixedly connected to the limiting block 2.

[0029] Reference Figure 3 , Figure 4 The cleaning mechanism 4 is positioned above the cleaning table 1. The cleaning mechanism 4 includes a drive screw 10, a limiting slide bar 8, cleaning rods 13, and a rotating rod 12. The drive screw 10 is vertically positioned, with a lifting frame 9 threaded onto its external side. The lifting frame 9 has an L-shaped structure, with one end fixedly connected to the limiting slide bar 8 and the other end rotatably connected to the rotating rod 12. Two opposing sliding cleaning rods 13 are located at the bottom of the rotating rod 12. An inner slider 16 is fixedly connected to the top of each cleaning rod 13 and slidably mounted on the bottom of the rotating rod 12. An inner groove is horizontally formed inside the rotating rod 12, and an inner screw 14 is rotatably mounted inside the inner groove. The threads on the outer wall of the inner screw 14 are reversed. The inner screw 14 is threadedly connected to the two sets of inner sliders 16. An adjusting head 15 for driving the inner screw 14 to rotate is mounted on the outer wall of the rotating rod 12. The internal rotation of the lifting frame 9 is through a rotating shaft 17, which is fixedly connected to the upper surface of the rotating rod 12. A rotating motor 11 is fixedly installed on the top of the lifting frame 9, and the rotating motor 11 is fixedly connected to the rotating shaft 17.

[0030] Reference Figure 2 , Figure 3 The cleaning table 1 has a vertically oriented drive hole 6 inside, and a drive screw 10 is rotatably mounted inside the drive hole 6. An inner sliding hole 5 is provided on the side of the drive hole 6, and a limiting slide rod 8 slides vertically into the inner sliding hole 5. A drive motor 7 is embedded inside the cleaning table 1, and the drive motor 7 is fixedly connected to the bottom of the drive screw 10.

[0031] Working principle: In use, first place the steel drum to be cleaned upright on the upper surface of the cleaning table 1. Then, extend the clamping cylinder 3, causing the limiting block 2 to move closer to the outer wall of the steel drum. The limiting block 2 clamps the outer wall of the steel drum. Then, the drive motor 7 starts, driving the drive screw 10 to rotate. The lifting frame 9 is lowered by force, causing the rotating rod 12 to move down synchronously. At this time, the cleaning rod 13 can be adjusted by rotating the adjusting head 15. The adjusting head 15 drives the inner screw 14 to rotate, and the two inner sliders 16 are subjected to force. The sliding motion causes the cleaning rod 13 to unfold, at which point the cleaning rod 13 has penetrated the inside of the steel drum. After the cleaning rod 13 is moved by the force, it adheres to the inner wall of the steel drum. The rotary motor 11 starts and drives the rotary rod 12 to rotate through the rotary shaft 17. The cleaning rod 13 cleans the inner wall of the steel drum. At this time, the cleaning fluid is sprayed onto the inside of the steel drum with the help of an external nozzle (not shown in the figure), making the cleaning rod 13 more efficient in cleaning the inner wall of the steel drum. After cleaning, the cleaning rod 13 is adjusted to rise and leave the inside of the steel drum.

[0032] Simply remove the steel bucket and replace it. After replacing the steel bucket, adjust the spacing of the cleaning rods 13 according to the diameter of the steel bucket.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
