Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parts rust removal, in particular to a rust removal device for mechanical parts. Background Art
[0002] Metal parts are susceptible to environmental factors during manufacturing, transportation, and storage, leading to the formation of iron oxide (rust) on their surfaces. This rust not only affects the appearance of the parts but can also reduce their performance and lifespan. Therefore, rust removal is a crucial step in metal surface treatment. Pickling, a traditional chemical rust removal method, is widely used in industry due to its high efficiency and cost-effectiveness.
[0003] Pickling rust removal utilizes an acidic solution to chemically react with oxides on the metal surface, converting the rust into a water-soluble substance. Commonly used acidic solutions include hydrochloric acid, sulfuric acid, phosphoric acid, and nitric acid. These acids react with rust (Fe2O3) to produce corresponding iron salts and water, thereby cleaning the metal surface. Currently, when using pickling rust removal methods for mechanical parts, the pickling solution may reach high concentrations in certain areas of the part, leading to localized over-corrosion. To address this issue, this application document provides a device for rust removal of mechanical parts. Summary of the Invention

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0020] The present application provides a device for rust removal of mechanical parts, which is mainly used to solve the problem that when the pickling method is currently used to remove rust on mechanical parts, the pickling solution may have a high concentration in certain areas of the parts, resulting in local over-corrosion, and provides the following technical solutions. Figures 1-4 Give detailed instructions:
[0021] A rust removal treatment device for mechanical parts mainly includes a treatment tank 1 and a stirring assembly 2. The bottom of the treatment tank 1 is provided with several evenly distributed supporting legs 11 to ensure the stability of the treatment tank 1 during operation. The top of the treatment tank 1 is provided with an opening and the top of the treatment tank 1 is hinged with a cover 12 that can close the opening to facilitate adding or removing parts. The treatment tank 1 is provided with a liquid inlet 13, a liquid outlet 14 and an exhaust port 15. The exhaust port 15 is used to discharge the gas generated during the treatment process. This design improves the convenience and safety of operation, while ensuring ventilation and gas discharge during the treatment process, reducing the danger of the operating environment. The stirring assembly 2 includes a motor 21 fixed in the middle of the bottom side of the treatment tank 1. The output end of the motor 21 is vertically upward and movable through the interior of the treatment tank 1. The interior of the treatment tank 1 is provided with a stirring blade 22 installed on the output end of the motor 21. The motor 21 drives the stirring blade 22 to rotate, driving the pickling liquid to stir, which helps to improve the rust removal efficiency, prevent local over-corrosion, and improve the rust removal quality.
[0022] In this example, see Figure 2 and Figure 3, a supporting cage 16 is provided inside the processing tank 1 that does not contact the inner wall of the processing tank 1. The outer wall of the supporting cage 16 is connected to the inner wall of the processing tank 1 by a number of connecting rods 17. The top of the supporting cage 16 is provided with an opening and the mechanical parts are located inside the supporting cage 16. The isolation design of the supporting cage 16 avoids direct contact between the parts and the processing tank 1, reduces the risk of local over-corrosion, and facilitates the loading and unloading of parts. The stirring blade 22 includes a rotating frame 221 fixed horizontally on the output end of the motor 21. The rotating frame 221 is located at the top of the supporting cage 16. Below, a number of evenly distributed spoiler blocks 222 are fixed on the rotating frame 221, and the spoiler blocks 222 are all located between the outer peripheral side of the supporting cage 16 and the inner peripheral side of the processing tank 1. The advantage of this design is that the mechanical parts are placed inside the supporting cage 16, and the motor 21 drives the rotating frame 221 to rotate, and the spoiler blocks 222 rotate. The spoiler blocks 222 will not directly contact the mechanical parts, but only drive the pickling liquid to flow, which not only ensures the efficiency of rust removal, but also prevents the spoiler blocks 222 from contacting the mechanical parts and causing damage to the parts.
[0023] For details, please refer to Figure 3 and Figure 4 The cross section of the spoiler block 222 is V-shaped and the tip of the V-shape of the spoiler block 222 is parallel to the tangent of the rotation direction of the output shaft of the motor 21. The design of the spoiler block 222 promotes the uniform flow of the pickling liquid, improves the rust removal effect, and reduces the dead corners of the liquid in the treatment tank 1.
[0024] Further, see Figure 2 and Figure 3 The supporting cage 16 is provided with an annular frame 18 inside the supporting cage 16, and a filter screen 181 is installed at the bottom of the annular frame 18. A number of through grooves 182 are opened on the circumferential side of the annular frame 18. Mechanical parts are placed above the filter screen 181. A pull handle 183 is fixed on the top of the filter screen 181. The filter screen 181 is installed inside the annular frame 18 to intercept metal debris and rust. The through groove 182 allows liquid to flow, and the pull handle 183 makes it easy for the operator to move the annular frame 18, so as to place the parts to be derusted inside the supporting cage 16, and also to take out the derusted parts.
[0025] For further information, see Figure 3 An observation window 19 is provided on the circumferential side of the treatment tank 1. The observation window 19 provides a safe observation method. The operator can monitor the rust removal process without direct contact with the pickling solution, thereby improving the safety of the operation.
[0026] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
