Description

Technical Field

[0002] With the substantial increase in the application scope and usage of titanium and titanium alloys, the amount of returned materials in the production process has also gradually increased. The reuse of returned materials after processing has become an effective means of energy saving and cost reduction. In the recycling process, since titanium and titanium alloy bulk materials are generally waste materials left over from processing and have not been properly preserved, their surfaces have varying degrees of oxide scale. Therefore, when recycling titanium and titanium alloy bulk materials, their surfaces need to be processed to improve the performance of the bulk materials and facilitate subsequent processing.

[0003] In order to improve the efficiency of titanium alloy surface treatment, the patent with announcement number CN209066002U discloses a closed titanium alloy macro corrosion production line. Although it realizes the mobility and closure of the production line, it only adopts a single corrosion treatment process and cannot simultaneously meet the complex process requirements such as pickling, alkali washing, and water blasting, which limits the scope of application of the production line. In addition, the workpiece conveying method of the existing production line mostly relies on fixed tracks or manual operation, with a low degree of automation, low efficiency, and difficulty in achieving precise control. Therefore, the existing technology has obvious deficiencies in process diversity and workpiece conveying automation, and it is difficult to meet the needs of efficient and flexible titanium alloy surface treatment.

The acid waste gas purification tower 13 adopts a two-stage purification tower, and the alkaline waste gas purification tower 14 adopts a three-stage purification tower; because the acid concentration used in acid washing in the general titanium alloy block material recycling surface treatment method is relatively small and the types are relatively small, and the two-stage purification tower can meet the purification requirements; while the alkali used in alkaline washing is generally high-concentration sodium hydroxide, and the three-stage purification tower can better meet the treatment requirements of high-concentration waste gas, and finally achieve standard emissions by gradually reducing the concentration of alkaline components in the waste gas.

[0037] In order to facilitate the classification of waste gas, the sealing cover 01 is divided into the first sealing chamber, the second sealing chamber and the third sealing chamber in the length direction by two lifting doors; the first sealing chamber is provided with loading and unloading tooling, multiple drying tanks 03 and multiple washing tanks 04, the second sealing chamber is provided with multiple pickling tanks 05, and the third sealing chamber is provided with multiple alkali washing tanks 06; columns 07 are provided on both sides of the sealing cover 01, and double-track steel beams 08 are provided on the above-mentioned columns 07, and the double-track steel beams 08 are slidably connected with a gantry crane 09, and the gantry crane 09 is connected with a lifting device 10 for lifting block materials. The second sealing chamber is used for acidic waste gas in the sealing chamber, the third sealing chamber is used for alkaline waste gas in the sealing chamber, and the first sealing chamber is used to prevent wastewater from splashing and polluting the surrounding environment. The first sealing chamber, the second sealing chamber and the third sealing chamber are divided by lifting doors, which is convenient for quickly switching the sealing state of each chamber and realizing flexible zoning.

[0038] In order to meet higher environmental protection requirements, the air inlet of the first air suction device 11 is connected to the second sealed chamber, and its air outlet is connected to the air inlet of the acid waste gas purification tower 13; the air inlet of the second air suction device 12 is connected to the third sealed chamber, and its air outlet is connected to the air inlet of the alkaline waste gas purification tower 14. That is, the waste gas is classified and recovered by the first air suction device 11 and the second air suction device 12, providing a basis for subsequent classification treatment, and the waste gas is classified and treated by the acid waste gas purification tower 13 and the alkaline waste gas purification tower 14.

[0039] The drying tank 03, the water washing tank 04, the pickling tank 05, and the alkali washing tank 06 are all provided with drain outlets, and each drain outlet is connected to the wastewater treatment device 15 through a main pipe. The wastewater from the drying tank 03, the water washing tank 04, the pickling tank 05, and the alkali washing tank 06 is centrally transported to the wastewater treatment device 15 through the main pipe, which is convenient for unified management and monitoring of wastewater discharge, and avoids the pollution of the environment caused by the random discharge of wastewater. Preferably, the dimensions of the drying tank 03, the water washing tank 04, and the pickling tank 05 are 4000×1200×2000mm, and the dimensions of the alkali washing tank 06 are 3600×1200×2000mm. The tank bodies of the drying tank 03, the water washing tank 04, and the pickling tank 05 adopt PPH tank bodies, and the tank body of the above-mentioned alkali washing tank 06 adopts Q245R tank bodies.

The lifting device 10 adopts a double lifting rail 101 design, and cooperates with the controller to realize accurate and stable lifting operation of the workpiece hanger 102, thereby improving production efficiency and safety.

[0042] The suction ports of the first suction device 11 are respectively arranged directly above the acid tank and on both sides of the notch; the suction ports of the second suction device 12 are respectively arranged directly above the alkaline tank and on both sides of the notch. The suction ports are arranged directly above the acid tank and the alkaline tank and on both sides of the notch, which can fully cover the tank body, effectively collect harmful gases such as acid mist or alkaline mist, and prevent them from spreading.

The above-mentioned controller is respectively connected to the control end of the pneumatic valve and the position sensor, and the above-mentioned controller is used to control the opening and closing of the pneumatic valve according to the position of the gantry crane 09. In this way, it can be avoided that the air suction device is still in the starting state when there is no need to collect exhaust gas, causing energy waste. The opening and closing of the pneumatic valve is automatically controlled according to the position of the gantry crane 09, so as to achieve precise air suction, improve efficiency and reduce energy consumption.

[0044] In order to prevent other substances from contaminating the cleaning liquid, the drying tank 03, the water washing tank 04, the acid washing tank 05 and the alkaline washing tank 06 all include a tank body and a tank cover; the tank cover is opened only when cleaning is required, and the tank cover is used to isolate other substances from the cleaning liquid. An air stirring component is provided at the bottom of the tank body; the control end of the air stirring component is electrically connected to the controller.

[0045] In order to improve the performance of alkali washing, an electric heating furnace is provided in the alkali washing tank 06, and the control end of the electric heating furnace is electrically connected to the controller to meet the temperature requirements during the surface treatment of the block material.

[0046] Walking support frames 17 for people to walk on are also arranged on both sides of the sealing cover 01, and a plurality of observation windows 18 are arranged on the sealing cover 01.

[0047] In order to improve the emergency handling capability of the production line, an accident pool 19 for storing waste liquid is also provided between the main pipe and the wastewater treatment device 15. The accident pool 19 adopts a reinforced concrete structure, and the volume range of the accident pool 19 is 70m³ to 100m³.

[0048] In order to facilitate the operation of the production line, the controller adopts a PLC controller, and also includes a touch display screen for being electrically connected to the PLC controller. The above controller is arranged in a control cabinet 16.

[0049] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention.
