Description

Technical Field

[0001] This utility model relates to the field of chemical equipment recycling technology, and in particular to a modular chemical drum cleaning spray system. Background Technology

[0002] Chemical drums, as standardized containers widely used in the industrial sector, are primarily used for storing and transporting liquid or solid chemical raw materials. They are typically made of polyethylene, stainless steel, or carbon steel with an anti-corrosion coating. Because chemical raw materials often possess volatile, corrosive, or cross-contamination properties, residual media after use can easily cause scaling on the drum walls and material deterioration. Recycling these drums can affect the purity of subsequent batches of materials. Therefore, thoroughly cleaning chemical drums after recycling is a necessary step to ensure production safety and meet environmental regulations.

[0003] Currently, most mainstream chemical drum cleaning equipment uses high-pressure water jet or rotary spray systems, primarily designed for cylindrical drums. Due to their symmetrical structure, cylindrical chemical drums can achieve 360° circumferential rinsing via a coaxial rotating spray arm, resulting in highly uniform water coverage. However, with the increasing demand for intensive warehousing, square containers are finding wider application in logistics and transportation due to their smaller stacking clearance. However, existing cleaning equipment is significantly less adaptable to square drums: their angular structure creates turbulent dead zones in traditional rotary spray systems, and the right-angled junctions between the sidewalls and bottom easily form cleaning blind spots, requiring manual rewashing or increasing cleaning time, greatly reducing operational efficiency.

[0004] While the surround spray pattern is suitable for cylindrical containers, it is less effective for square containers. In the right-angled areas, the jet energy attenuates due to hydrodynamic characteristics, making it difficult to remove stubborn deposits. To cover all surfaces, this necessitates longer spraying times or increased water pressure, resulting in a double waste of water and energy. This form-dependent problem forces companies to compromise between storage space utilization and cleaning costs, hindering the overall efficiency optimization of chemical container management. Utility Model Content

[0005] To overcome the shortcomings of poor cleaning compatibility, this utility model provides a modular chemical drum cleaning spray system with good compatibility.

[0006] A modular chemical drum cleaning spray system includes a cleaning frame and a telescopic rod. The top of the cleaning frame is connected to an upper plate and a lower plate that are parallel to each other and of the same size. The lower plate is located below the upper plate. A rotary motor is installed in the middle of the bottom of the lower plate. One end of the telescopic rod is connected to the output shaft of the rotary motor, and the other end is connected to a water pipe. Several nozzles are provided at the lower end of the water pipe. The upper end of the water pipe is slidably connected to the lower plate. The lower plate is provided with a track assembly with different guide tracks for guiding the movement of the water pipe. The upper plate is provided with a switching mechanism for the guide tracks of the pipe-cutting track assembly.

[0007] More preferably, the track assembly includes a first limiting plate and a second limiting plate. The lower end of the upper plate is connected to several connecting plates, and a guide block is connected to the bottom of every two connecting plates. The guide block is at the same height as the lower plate. The first limiting plate and the second limiting plate are slidably connected inside the lower plate. The guide block is located between the first limiting plate and the second limiting plate. The lower plate, the guide block, and the second limiting plate form a circular track. Alternatively, the lower plate, the guide block, and the first limiting plate form a square track. The gap between the first limiting plates is greater than the diameter of the water pipe.

[0008] More preferably, the switching mechanism includes a gear, a switching motor is mounted on the upper plate, several guide rods are provided between the upper plate and the lower plate, the output shaft of the switching motor faces downward and is fixedly connected to a lead screw, the moving plate is slidably connected to the guide rods, the lead screw is threadedly connected to the moving plate, the four ends of the moving plate are connected to the first limiting plate, the gear is rotatably connected between the two connecting plates, a first rack is connected to the outer end of the first limiting plate, a second rack is connected to the inner side of the second limiting plate, the first rack and the second rack both mesh with the gear and are located on both sides of the gear respectively.

[0009] More preferably, the water pipe is equipped with several brushes, and the brushes are spaced apart from the nozzle.

[0010] More preferably, the bottom of the cleaning rack is connected to a wastewater tank, and the top plate of the wastewater tank is hollowed out.

[0011] More preferably, an annular baffle is slidably connected to the outside of the sewage tank, and the baffle is made of plastic.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By cooperating with the track assembly and the switching mechanism, the switching motor drives the lead screw and gear rack transmission, and the first limit plate and the second limit plate move in opposite directions to form a circular or square guide track, realizing dynamic adaptation of multi-form cleaning paths, adapting to cylindrical and square containers, improving the flexibility of the production line, and reducing the enterprise's multi-container management costs.

[0014] 2. Through the collaboration of the telescopic rod and the rotary motor, the rotary motor drives the water pipe to move along the square track. The telescopic rod adaptively extends and retracts at the corners to adjust the distance between the nozzle and the barrel wall, ensuring that the nozzle maintains a constant spray pressure in the right-angle area. Combined with the elastic deformation of the brush, it eliminates the blind spots in the right-angle area of ​​the square barrel. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: A modular chemical drum cleaning spray system, such as Figures 1-3 As shown, the system includes a cleaning rack 1, an upper plate 101, a lower plate 102, a rotary motor 2, a water pipe 3, a telescopic rod 4, nozzles 11, a track assembly, and a switching mechanism. The top of the cleaning rack 1 is connected to the upper plate 101 and the lower plate 102, which are parallel to each other and of the same size. The lower plate 102 is located below the upper plate 101. A disc is set in the middle of the bottom of the lower plate 102, and the rotary motor 2 is installed on the bottom surface of the disc. One end of the telescopic rod 4 is connected to the output shaft of the rotary motor 2, and the other end is connected to the water pipe 3. Several nozzles 11 are set at the lower end of the water pipe 3. The upper end of the water pipe 3 is slidably connected to the lower plate 102. After the rotary motor 2 is started, it drives the water pipe 3 to rotate at a constant speed along a circular track through the telescopic rod 4. The nozzles 11 spray high-pressure water in a radial pattern to rinse the chemical drum. The lower plate 102 is provided with a track assembly with different guide tracks. The track assembly is used to guide the movement of the water pipe 3. The upper plate 101 is provided with a switching mechanism for the guide track of the pipe cutting track assembly.

[0021] like Figure 2 and Figure 3As shown, the track assembly includes a connecting plate 103, a guide block 104, a first limiting plate 7, and a second limiting plate 10. Eight connecting plates 103 are connected to the lower end of the upper plate 101. A guide block 104 is connected to the bottom of every two connecting plates 103. The guide blocks 104 are at the same height as the lower plate 102. The first limiting plate 7 and the second limiting plate 10 are slidably connected within the lower plate 102. The guide blocks 104 are located between the first limiting plate 7 and the second limiting plate 10. The disc in the middle of the lower plate 102, the inner sides of the four guide blocks 104, and the second limiting plate 10... The limiting plate 10 forms a circular track 1001. The inner side of the lower plate 102 frame, the outer side of the four guide blocks 104, and the first limiting plate 7 form a square track 1002. The guide blocks 104 serve as track reference points and form a complete circumferential boundary with the second limiting plate 10 in circular mode. When switching to square mode, the first limiting plate 7 expands outward to form four sides, and the guide blocks 104 serve as corner positioning points. The gap between the first limiting plates 7 is greater than the diameter of the water pipe 3, ensuring that the water pipe 3 can smoothly transition to the new path when switching tracks, avoiding mechanical interference.

[0022] like Figure 2 and Figure 3 As shown, the switching mechanism includes a switching motor 5, a lead screw 6, a moving plate 601, a gear 8, a first rack 9, and a second rack 901. The switching motor 5 is mounted on the upper plate 101. Four guide rods are arranged between the upper plate 101 and the lower plate 102. The output shaft of the switching motor 5 faces downward and is fixedly connected to the lead screw 6. The moving plate 601 is slidably connected to the guide rods. The lead screw 6 is threadedly connected to the moving plate 601. The four corners of the moving plate 601 are fixedly connected to four first limiting plates 7 respectively. The gear 8 is rotatably connected between two connecting plates 103. The outer end of the first limiting plate 7 is connected to the first rack 9, and the inner side of the second limiting plate 10 is connected to the second rack 901. The first rack 9 and the second rack 901 both mesh with the gear 8 and are located on both sides of the gear 8 respectively.

[0023] like Figure 2 As shown, it also includes a brush 12. Several brushes 12 are installed on the water pipe 3, and the brushes 12 and the nozzles 11 are distributed at intervals. The tips of the brushes 12 are close to the wall of the tank. The brushes 12 peel off the attached dirt by rotating and rubbing. The nozzles 11 spray water behind the brushes 12 to wash away the loose dirt in time and avoid secondary deposition.

[0024] like Figure 2 As shown, it also includes a sewage tank 14, and the bottom of the cleaning rack 1 is connected to the sewage tank 14, with the top plate of the sewage tank 14 being hollowed out.

[0025] like Figure 2 As shown, it also includes a baffle 13. The sewage tank 14 is slidably connected to an annular baffle 13. The baffle 13 is made of plastic and has the characteristics of being lightweight and not easily corroded.

[0026] Workers place the chemical drums to be cleaned onto the wastewater tank 14, and then select the corresponding cleaning track according to the shape of the chemical drum. If it is a round drum, a circular track 1001 is selected. The second limiting plate 10 is inserted into the lower plate 102. The second limiting plate 10 cooperates with the guide block 104 and forms a circular track 1001 with the circular plate in the middle of the lower plate 102. Then, the rotary motor 2 is started, and the water pipe 3 is driven to rotate through the telescopic rod 4, thereby driving the nozzle 11 and brush 12 to clean the chemical drum. The wastewater generated during cleaning flows into the wastewater tank 14. The chemical wastewater needs to be treated before it can be discharged. The baffle 13 can prevent the water sprayed by the nozzle 11 from splashing around after spraying the chemical drum during cleaning, thereby keeping the outside dry. When picking up or putting down the chemical drum, simply lift the baffle 13 upwards.

[0027] When the chemical drum is square, the switching motor 5 is started, which drives the lead screw 6 to rotate. The lead screw 6 pushes the moving plate 601 to slide downward along the guide rod. The four first limiting plates 7 follow the moving plate 601 to move downward. The first rack 9 on the outer side of the first limiting plate 7 moves downward. Through the meshing gear 8, the second rack 901 and the second limiting plate 10 slide upward. At this time, the water pipe 3 is pulled outward from the gap between the two guide blocks 104 and enters the square track 1002. The moving distance of the second limiting plate 10 is equal to the length of the top of the water pipe 3 inserted into the lower plate 102. At this time, the second limiting plate 10 is still inserted into the lower plate 102. The switching motor 5 is turned off, and the distance that the first limiting plate 7 descends closes the circular track 1001. At this time, the rotary motor 2 is started, and the water pipe 3 moves along the square track 1002. The telescopic rod 4 ensures the connection between the water pipe 3 and the output shaft of the rotary motor 2, ensuring continuous rotation and completing the cleaning process of the chemical drum.

[0028] Although this disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made to this disclosure without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents. Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
