Description

Technical Field

[0001] The utility model relates to a titanium processing device, in particular to a rust removal device for titanium processing. Background Art

[0002] Rust removal is a crucial step in the titanium processing industry, directly impacting the surface quality of the titanium material and the efficiency and effectiveness of subsequent processing. Traditional rust removal methods often rely on single-use spraying or immersion methods. For large or complex titanium materials, achieving ideal rust removal requires the use of sufficient pickling fluid, which is typically discharged after use. This not only significantly wastes the pickling fluid but also significantly increases the cost of wastewater treatment.

[0003] Therefore, it is particularly important to develop a rust removal device for titanium processing that can realize the recycling of pickling waste liquid. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned background technology, the utility model provides a rust removal device for titanium processing, which realizes the recycling of rust removal waste liquid for titanium materials.

[0005] The technical solution is: a rust removal device for titanium processing, comprising a feed mechanism, an outer hood provided with a first, second, and third spray mechanisms disposed within the hood in sequence along the feed direction of the feed mechanism, and a liquid collection tank at the bottom of the hood. The liquid collection tank is divided by baffles into primary, secondary, and tertiary tanks, which respectively receive liquid released by the first, second, and third spray mechanisms. The tertiary and secondary tanks are connected to the first spray mechanism via one-way pipes. The primary, secondary, and tertiary tanks are provided to collect the cleaning waste liquid from the first, second, and third spray mechanisms, respectively. The first spray mechanism primarily removes impurities and oil stains. The waste liquid in the primary tank, which contains too many impurities, cannot be used and is directly discharged. The acid liquid after fine washing by the second spray washing mechanism is collected and temporarily stored, and the third spray washing mechanism cleans the acid liquid remaining on the surface of the titanium material. The waste liquid collected in the tertiary pool is a weak acid liquid mixed with acid and water. The acid liquid and the acid-water mixture in the secondary and tertiary pools are added to the first spray washing mechanism for preliminary surface impurity removal and cleaning. Through the above-mentioned circulation system, not only acid liquid resources are saved, but also environmental pollution is reduced.

[0006] Furthermore, a clear liquid area and a turbid liquid area are respectively provided in the second and third pools, and the clear liquid area and the turbid liquid area are separated by a filter plate. The turbid liquid areas of the second and third pools are respectively used to receive the liquid released by the second and third spraying mechanisms, and enter the corresponding clear liquid area for recycling after being filtered by the filter plate.

[0007] Furthermore, it also includes a sewage pipe, and the turbid liquid areas of the second and third pools and the first pool are respectively connected to the sewage pipe.

[0008] Furthermore, a particle adsorption plate is provided in the middle or on both sides of the filter plate.

[0009] Furthermore, the one-way pipeline includes a pipeline and a one-way valve for controlling the flow of the pipeline.

[0010] Furthermore, the first, second and third spraying mechanisms each include upper and lower cleaning heads, a raw liquid supply tank and a water suction pump; the cleaning head is connected to the raw liquid supply tank through a raw liquid pipe, and the water suction pump is connected to the raw liquid pipe.

[0011] The beneficial effects are as follows: Through the rational layout and coordination of the three-stage spray cleaning mechanism, this utility model achieves efficient rust removal of titanium materials, improving the quality and efficiency of rust removal. The acid and mixed liquid from the secondary and tertiary tanks are added to the first spray cleaning mechanism for use as cleaning fluid in the primary rust removal process, significantly saving acid resources. By recycling waste liquid, this utility model reduces the emission of harmful substances and reduces environmental pollution. Furthermore, resource conservation reduces production costs, conforming to the development trend of green manufacturing, and has high promotion value and application prospects.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings. Figure 1-2 The rust removal device for titanium processing shown in the figure comprises a feed mechanism 1, a hood 2, a first spray mechanism 3a, a second spray mechanism 3b, a third spray mechanism 3c, and a liquid accumulation tank. The feed mechanism 1 is used to transport the titanium material to be rust-removed. The hood 2 covers the outside of the feed mechanism 1, forming a semi-enclosed working environment. The hood 2 has a feed inlet at one end and a discharge outlet at the opposite end. The first, second, and third spray mechanisms 3a, 3b, and 3c are positioned within the hood 2 in sequence along the feed direction, respectively, to perform preliminary impurity removal, fine cleaning, and residual acid cleaning on the titanium material. The liquid accumulation pool is divided into a primary pool 4a, a secondary pool 4b, and a tertiary pool 4c by a baffle. The primary pool 4a is used to receive the liquid released by the first spray cleaning mechanism 3a, the secondary pool 4b is used to receive the liquid released by the second spray cleaning mechanism 3b, and the tertiary pool 4c is used to receive the liquid released by the third spray cleaning mechanism 3c. The waste liquid in the primary pool 4a, because it contains a large amount of impurities and oil, is generally not reusable and must be discharged through a sewage pipe 7. The secondary pool 4b and the tertiary pool 4c respectively collect the acid solution after fine washing and the weak acid mixture remaining after washing. To achieve resource recycling, the device is designed with a one-way pipe 6 to replenish the acid solution in the secondary pool 4b and the acid-water mixture in the tertiary pool 4c to the first spray cleaning mechanism 3a for preliminary impurity removal and cleaning of the titanium surface. After the acid solution in the secondary pool 4b is mixed with the mixed solution in the tertiary pool 4c, the acid solution is diluted to meet the pickling requirements of the cleaning solution of the first spray cleaning mechanism 3a.

[0021] It should be noted that the cleaning fluid used by the first spraying mechanism 3a is a weak acid or distilled water, which is mainly used to rinse the impurities on the surface of the titanium material and remove the oxide scale, rust and other impurities on the surface of the titanium material. The cleaning fluid used by the second spraying mechanism 3b is mainly hydrochloric acid (HCl), sulfuric acid (H2SO4) or a mixture thereof, which is mainly used to perform fine cleaning on the surface of the titanium material, and a chemical reaction occurs between the acid and the metal oxide to generate soluble salts and water, thereby achieving the purpose of rust removal. After the fine cleaning is completed, the third spraying mechanism 3c releases distilled water to quickly rinse the surface of the titanium plate to remove all acid residues. Subsequently, a hair dryer can be used to dry the surface of the titanium plate to ensure that it is dry and water-free. Through the above-mentioned circulation system, not only acid resources are saved, but also the purification and discharge costs of waste acid are reduced.

[0022] In a preferred embodiment, if Figure 3 As shown, both the secondary tank 4b and the tertiary tank 4c are equipped with a clear liquid area 42 and a turbid liquid area 41, separated by a filter plate 5. The turbid liquid area 41 receives liquid released by the spraying mechanism, which is filtered by the filter plate 5 before entering the clear liquid area 42 for recycling. This design further improves waste liquid treatment efficiency and resource utilization. Furthermore, a drain pipe 7 is connected to the turbid liquid areas 41 of the secondary and tertiary tanks 4c and the primary tank 4a, allowing for the discharge of unrecyclable waste liquid when necessary.

[0023] like Figure 6 As shown, the one-way pipeline 6 includes a pipeline 61 and a one-way valve 62. The one-way valve 62 controls the flow of the liquid in the pipeline 61, and the one-way valve 62 is a solenoid valve.

[0024] like Figure 4 As shown, in addition to the filter plate 5, a multi-stage filtration system can be added. A particle adsorption plate 51, an activated carbon filter layer, an ion exchange resin layer, etc. can be placed in the middle or on both sides of the filter plate 5 to further remove impurities and metal ions in the acid solution. The specific application situation can be selected according to the actual acid solution used and the processing technology.

[0025] like Figure 1 and Figure 5 As shown, the structures of the first spray mechanism 3a, the second spray mechanism 3b and the third spray mechanism 3c are exactly the same, and all include an upper and lower cleaning head 31, a raw liquid supply tank 32 and a water suction pump 34; wherein, the cleaning head 31 is connected to the raw liquid supply tank 32 through a raw liquid pipe 33, and the water suction pump 34 is connected to the raw liquid pipe 33. The cleaning head 31 and the raw liquid pipe 33 are made of titanium alloy, ceramics, etc. to extend the service life of the equipment.

[0026] Furthermore, in a preferred embodiment, an acid concentration detection device is installed on the raw liquid pipe 33 of the first spray mechanism 3a of the present device. The device automatically adjusts the amount of replenishing liquid based on the detection result to maintain the acid concentration within an appropriate range. Specifically, the mixing ratio of the acid and water is adjusted by controlling the flow rates of the one-way valve 62 of the one-way pipe 6 connecting the secondary tank 4b and the one-way valve 62 of the one-way pipe 6 connecting the tertiary tank 4c.

[0027] In a preferred embodiment, pressure sensors and angle adjustment mechanisms (not shown) are installed on the upper and lower cleaning heads 31 to adjust the spray pressure and angle in real time based on the cleaning progress and results, ensuring uniform and efficient cleaning. Furthermore, the nozzles of the upper and lower cleaning heads 31 preferably utilize microporous or swirl nozzles to enhance the atomization of the spray liquid, increase the contact area with the titanium surface, and thus improve cleaning efficiency. By optimizing the structure and operating mode of the spray mechanism, cleaning becomes more uniform and efficient, reducing cleaning time and water consumption.

[0028] It should also be noted that this device is also equipped with an intelligent control system. This integrated intelligent control system integrates the control of the feed mechanism 1, the spraying mechanisms (first spraying mechanism 3a, second spraying mechanism 3b, and third spraying mechanism 3c), the one-way valves 62, the water suction pumps 34, the acid concentration detection device, and other equipment, enabling remote monitoring and automatic adjustment. This allows for more precise detection, adjustment, and control of the cleaning liquid's acid concentration and impurity removal, thereby improving the acid recovery efficiency and service life.

[0029] In another preferred embodiment, a plurality of observation windows 8 are provided on the top of the hood 2. The observation windows 8 can be opened to facilitate observation of the processing status and maintenance of the components in the liquid accumulation pools.

[0030] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention. Based on the explanations herein, those skilled in the art will be able to conceive of other specific implementations of the embodiments of the present invention without inventive effort, and these implementations will fall within the scope of protection of the embodiments of the present invention.
