[0002] During the recycling process of scrap steel drums, the inner wall of the polished drums needs to be treated with rust prevention. The current production process is to spray rust inhibitors on the inner surface of the drums, so that the drums and the rust inhibitors react chemically to form a protective film to prevent rust.

[0003] At present, the traditional anti-rust spray pipe only has a spray port on the top. This type of structure is only suitable for anti-rust spraying of steel drums in a vertical state. During the anti-rust spraying operation, the spray pipe only sprays the bottom of the steel drum. After the rust inhibitor is sprayed to the bottom of the steel drum, the rust inhibitor flows down along the drum wall due to gravity, and then performs anti-rust treatment on the drum wall. This spraying operation easily causes the rust inhibitor to not be sprayed on the inner wall of the steel drum, resulting in uneven rust prevention.

[0004] Based on this, a steel drum rust-proof spray pipe and device are needed, which uses a 90-degree bent pipe and multiple spray nozzles to provide a uniform spray effect to solve the above problems. Utility Model Content

[0034] Existing rotary dehumidifiers for recycling scrap steel drums 5 all utilize a spray system with a spray pipe to provide rust prevention. However, conventional spray pipes are mostly straight, which results in incomplete spraying of the drums 5 and creates blind spots. Consequently, achieving uniform spraying of the drums 5 using the spray pipe and spray system has become an urgent industry challenge.

[0035] Example 1:

[0036] like Figure 3As shown, the steel drum anti-rust spray pipe includes a spray main pipe 1, a spray hole (not shown in the figure) and a nozzle 12. The spray main pipe 1 is a 90-degree bend pipe, and the specific structure is that one side is set as the side wall spray area (long pipe) and the other side is set as the bottom wall spray area (short pipe). The nozzle 12 is connected to each section of the spray main pipe 1 through the spray hole to ensure uniform spray coverage; 3 nozzles 12 are set on the long pipe of the spray main pipe 1, and 2 nozzles 12 are set on the short pipe. The number of nozzles 12 is 5, which can ensure uniform spraying of the inner and outer surfaces of the steel drum 5; it should be understood that in this embodiment, setting the side wall spray area as a long pipe and setting the bottom wall spray area as a short pipe is only preferred, and it should not be understood that the side wall spray area must be longer than the bottom wall spray area.

[0037] It should be noted that the nozzle 12 can be integrally formed with the spray hole, the nozzle 12 can also be welded to the spray hole, or the nozzle 12 can be detachably connected to the spray hole.

[0038] In a preferred embodiment, the spray holes are evenly arranged at the long tube and the short tube to achieve uniform spraying of the steel barrel 5 .

[0039] In a preferred embodiment, Figure 3 The spray hole shown is provided with a connector 11, which is provided with an internal thread, and a nozzle 12 is installed on the connector 11; since most nozzles on the market are connected through internal threads, the setting of the connector 12 can improve the versatility of the steel barrel anti-rust spray pipe.

[0040] The spray holes are arranged at the curved part and both ends of the spray main pipe 1, and the nozzle 12 is connected to the spray hole by a thread and can be disassembled and replaced as needed; when the nozzle 12 is blocked or worn due to long-term use, it can be quickly disassembled for cleaning or replacement, and there is no need to replace the entire steel barrel anti-rust spray pipe, which reduces maintenance costs; different anti-rust requirements may require different types of nozzles 12, such as different spraying angles or spraying patterns. The detachable design allows the nozzle 12 to be flexibly replaced according to specific needs, and nozzles 12 of different specifications or functions can be quickly replaced to adapt to different process requirements and operating environments.

[0041] In this solution, the anti-rust spraying operation is optimized by improving the structure of the steel drum anti-rust spraying pipe, so that the anti-rust agent is sprayed more evenly on the inner wall of the steel drum, and the spraying without dead angles on the inner surface of the steel drum can be achieved, thus making the steel drum anti-rust more ideal.

[0042] Example 2:

[0043] like Figure 4As shown, in this embodiment, compared with the first embodiment, in this embodiment, the nozzle 12 of the steel drum anti-rust spray pipe adopts a fan-shaped structure, and the spraying angle is 90°-135°, preferably a nozzle with a spraying angle of 90° or 135°; the steel drum anti-rust spray pipe has a large spray coverage area, which can ensure that the anti-rust liquid evenly covers the surface of the steel drum 5; the material of the nozzle 12 can be selected from corrosion-resistant materials, such as stainless steel or engineering plastics, to increase its service life; the interior of the nozzle 12 is provided with evenly distributed spray grooves to ensure that the sprayed anti-rust liquid is in a uniform water mist, effectively covering every corner of the steel drum 5; the nozzle 12 is connected to the connecting head 11 through an adjustable mechanism, and the adjustable mechanism is preferably a ball joint.

[0044] It should be noted that the design of the spray main pipe 1 takes into account the size and shape of the steel drum 5. By reasonably setting the position and angle of the nozzle 12, it is ensured that the rust-proof liquid can cover the inner and outer surfaces of the steel drum 5; the long pipe is provided with 3 nozzles 12, and the short pipe is provided with 2 nozzles 12. The long and short pipes are connected at 90 degrees, so that the rust-proof liquid spray coverage is more comprehensive.

[0045] In this embodiment, the steel barrel anti-rust spray pipe, the fixing mechanism and the rotating mechanism constitute a steel barrel anti-rust spray device. The steel barrel anti-rust spray pipe is detachably connected to the fixing mechanism. The steel barrel anti-rust spray pipe is placed inside the steel barrel 5. The rotating mechanism is connected to the steel barrel 5 to drive it to rotate. The eccentrically arranged steel barrel anti-rust spray pipe can fully cover the spray range of the inner wall of the steel barrel 5.

[0046] Preferably, in the steel drum anti-rust spray device of this embodiment, the steel drum anti-rust spray pipe is detachably connected to the rotating mechanism, and the steel drum anti-rust spray pipe is placed inside the steel drum 5, and the steel drum 5 is locked by the fixing mechanism; the rotating mechanism drives the steel drum anti-rust spray pipe to rotate so as to achieve full coverage of the spray range of the inner wall of the steel drum 5.

[0047] Example 3:

[0048] like Figure 3 As shown, the steel drum anti-rust spray system includes a steel drum anti-rust spray device, a connecting pipe 2, a control valve 3 and a spray pump 4; one end of the spray main pipe 1 of the steel drum anti-rust spray device is connected to the connecting pipe 2, and the connecting pipe 2 is connected to the spray pump 4. The spray pump 4 is used to provide pressure to transport the anti-rust liquid to the spray main pipe 1; the control valve 3 is installed on the connecting pipe 2 to control the flow and switch of the anti-rust liquid.

[0049] The control valve 3 is preferably a solenoid valve, which controls its switching state through electrical signals, thereby realizing automatic control and improving the convenience and accuracy of operation; the operation of the control valve 3 can be managed by a PLC or other automated control system to achieve precise control and monitoring.

[0050] The selection of the spray pump 4 should be determined according to the actual needs of the system to ensure that it can provide sufficient pressure and flow to evenly spray the anti-rust liquid on the surface of the steel drum 5. The spray pump 4 can be a centrifugal pump or a plunger pump. The specific selection should be determined according to the flow requirements of the system and the properties of the anti-rust liquid.

[0051] In actual applications, the length of the spray main pipe 1 and the number of nozzles 12 can be adjusted according to the rust prevention requirements of different types of steel drums 5. For example, for larger steel drums 5, the number of nozzles 12 and the length of the spray main pipe 1 can be increased to ensure that the rust prevention liquid can fully cover the surface of the steel drum 5. Accordingly, the flow rate and pressure of the spray pump 4 also need to be adjusted to meet the spraying requirements of the system.

[0052] In addition, in order to further improve the anti-rust effect, a filter device can be added to the spray system to filter impurities in the anti-rust liquid and prevent clogging of the nozzle 12. The filter device can be installed at the inlet and outlet of the spray pump 4, and the filter element can be cleaned or replaced regularly to ensure the normal operation of the system.

[0053] Example 4:

[0054] like Figure 4 As shown, compared with the above embodiment, the steel drum anti-rust spraying system in this embodiment is used for horizontal spraying of the steel drum 5, and the connection relationship between the various components is the same as that in the above embodiment.

[0055] In this embodiment, the steel drum anti-rust spray system includes a spray pipe 1, a connecting pipe 2, a control valve 3, and a spray pump 4. The spray pipe 1 can be arranged vertically or horizontally as needed, and the nozzle 12 on the spray pipe 1 can achieve spraying in different directions by adjusting the angle of the connector 11.

[0056] In the vertical spraying mode, the steel barrel is placed vertically, the spray pipe 1 is arranged along the height direction of the steel barrel 5, and the nozzles 3 are evenly distributed on the spray pipe 1 to ensure that the rust-proof liquid covers the inner surface and bottom of the steel barrel 5 from top to bottom.

[0057] In the horizontal spraying mode, the steel drum 5 is placed horizontally, the spray pipe 1 is arranged along the length direction of the steel drum 5, and the nozzles 3 are evenly distributed on the spray pipe 1 to ensure that the rust-proof liquid covers the inner surface and bottom of the steel drum 5 from left to right.

[0058] In this solution, the steel drum anti-rust spray system can adapt to different steel drum 5 placement methods, whether vertical or horizontal, and can perform effective anti-rust spray treatment; the steel drum anti-rust spray system can flexibly adjust the spray mode according to the layout and operation requirements of the production line to adapt to different production environments and process requirements; according to the layout and space limitations of the production workshop, vertical or horizontal spraying methods can be flexibly selected to optimize equipment layout and improve space utilization; in workshops with relatively small space, vertical spraying method can be used; in workshops with more horizontal space, horizontal spraying method can be used to flexibly respond to different site conditions.

[0059] Through the detailed description of the above embodiments, it can be seen that the steel drum anti-rust spray pipe and system provided by the utility model have the advantages of simple structure, easy use, uniform spraying, and comprehensive coverage. It can significantly improve the anti-rust effect of the steel drum 5, extend its service life, and has high practical value. The steel drum anti-rust spray pipe of the present application is eccentrically installed in the steel drum 5 that needs to be rust-proofed. The steel drum 5 rotates slowly at a certain speed. During this process, the five groups of nozzles fully spray the rust inhibitor onto the circumferential inner wall of the steel drum 5 and the bottom of the steel drum 5, spraying evenly to avoid dead corners in the spraying. The new steel drum anti-rust spray pipe can be used for vertical spraying operations of the steel drum 5, and can also be used for horizontal spraying operations of the steel drum 5 for anti-rusting, which facilitates the structural design of the spraying station and has a wider range of applications.

[0060] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
