Description

Technical Field

[0001] The invention relates to the technical field of cleaning special-shaped workpieces, and in particular to a surface cleaning and drying device for a rocket thrust chamber component. Background Art

[0002] The thrust chamber is a component in a rocket engine that converts propellant energy and generates thrust. It is the core component of a liquid rocket engine and is responsible for the mixing, combustion, and thrust generation of fuel and oxidizer.

[0003] Manufacturing residues are easily generated during the processing of rocket thrust chambers, such as metal debris, oil stains, anti-rust coatings, etc., and due to its extreme working environment (high temperature, high pressure, high speed), carbon deposits, oxides, and unburned fuel residues are easily generated after long-term use. At the same time, if the residual chemicals are not cleaned in time, it may cause material corrosion, thereby reducing the structural strength. Cleaning the surface of the rocket thrust chamber is a prerequisite for ensuring the effective operation of the seals. Therefore, cleaning the rocket thrust chamber is a key step in manufacturing, maintenance and repair, which directly affects the engine performance and reliability.

[0004] However, there is no cleaning equipment specifically used for cleaning rocket thrust chamber components in the prior art. For the cleaning of such special-shaped workpieces, manual cleaning is often the only way to comprehensively clean them, which is not only inefficient but also very cumbersome. Therefore, there is a need for a cleaning equipment specifically used for rocket thrust chamber components to improve the cleaning efficiency of the rocket thrust chamber. Summary of the invention

Two pipe fittings 8 are provided for the nozzle mechanism and the blowing mechanism, one of which is arranged on the inner wall of the second main tank body 31 and the third main tank body 41 on the outside of the thrust chamber assembly of the hoisting rocket, and the other pipe fitting 8 is arranged at the center of the bottom surface of the second main tank body 31 and the third main tank body 41 in the vertical direction, and a plurality of nozzles are provided on the pipe fitting 8.

[0062] like Figure 4 or Figure 5As shown, the first main tank body 21, the second main tank body 31, and the third main tank body 41 are all provided with automatic covers 25, which are formed by welding of high-quality 2mm / SUS304 stainless steel plates, equipped with observation windows, and filled with thermal insulation materials; equipped with cylinders, through the movement of the cylinders, the upper covers can be opened 90 degrees upwards.

[0063] It should be noted that the rack 1 is also equipped with an electrical control cabinet, the control panel is located on the operating side, the whole set of equipment is equipped with a main control power cabinet and each sub-slot control part, the main control cabinet is equipped with a main power control, the original parts of each slot control part are installed in the front of each slot body, and the circuit and switch panel are detachable. The functions of each system can be completed manually, including switching ultrasonic cleaning, cyclone rinsing, and circulation filtration.

[0064] The method of using the above equipment is as follows:

[0065] 1) Equipment form: Cleaning cycle: 10-15min / time adjustable.

[0066] 2) Types of pollutants to be cleaned: cleaning of oil, dust, other stains and other residues on the surface of parts.

[0067] 3) Cleaning medium: city water + cleaning agent, the cleaning agent model is ZTD-03A (or other environmentally friendly solvents with good cleaning effects).

[0068] 4) Cleaning process: manual loading → ultrasonic cleaning → submerged swirl → rotary spray → rinsing → rotary drying → manual unloading, as follows:

[0069] Manual loading: The operator places the parts to be cleaned on the cleaned positioning fixture 52, and then installs the lifting bracket 51. After the assembly is completed, the operator lifts the special fixture 5 into the loading station through the electric hoist 12. The pressing block 54 has an inclination angle close to the parts, which can control both the lateral sliding and the longitudinal sliding of the parts. The slider of the positioning fixture 52 is replaceable. The lifting bracket 51 and the positioning fixture 52 adopt a snap-on detachable assembly method to facilitate the installation of parts. The middle plug is wrapped with plastic, and a protective cover 55 is selected for the corresponding product.

[0070] Ultrasonic cleaning and submerged cyclone: ​​The inner and outer surfaces of parts are cleaned by ultrasonic combined with cleaning agent + submerged cyclone. The cleaning temperature is 30°C and the cleaning time is 30 minutes. Different times and temperatures can be set according to actual cleaning needs. First, the dirt is infiltrated and dissolved by the chemical action of the cleaning agent. The impact force generated by the "cavitation effect" of the ultrasonic vibration box 22 peels off the dirt layer on the surface of the object, and the submerged cyclone cleaning system is used for stirring and dispersion. After the ultrasonic cleaning operation is completed, the cyclone starts, and the multi-angle cyclone rinse makes it easier to clean some impurities and multi-notch parts that are difficult to clean, achieving better results, and the cyclone and ultrasonic waves are controlled separately. A 40Hz ultrasonic transducer is used, and the ultrasonic vibration box 22 is arranged at the bottom and four sides, and the ultrasonic wave is evenly distributed. The material rack enters and exits from the top of the first main tank body 21. The first main tank body 21 is surrounded by feeding guide rods to ensure that the material enters and exits the center of the first main tank body 21. The cleaning liquid sprinkled during the cleaning process flows back into the first main tank body 21 through the guide inclined plate on the side of the first main tank body 21. The overflow port is directly connected to the liquid storage tank of the first main tank body 21, equipped with a circulating filtration system 9.

[0071] Rotary spraying and rinsing: The second main tank 31 is provided with a rotating tray 6 and a driving mechanism, which is driven by a motor 7 to rotate the rotating tray. The pipe fitting 8 is fixed on the adjusting cylinder 13. The distance between the nozzle on the pipe fitting 8 and the parts is controlled by the stroke of the automatic adjusting cylinder 13 to achieve close-range spray cleaning. The nozzle automatically extends after closing the automatic cover 25 and automatically retracts after opening the automatic cover 25. It can be adjusted adaptively. The pipe fitting 8 is arranged on the inside and outside of the parts respectively. The nozzles of the pipe fittings are evenly arranged to ensure no dead angle cleaning, making it easier to clean some multi-groove parts that are difficult to clean, and achieving better results. The pipe fitting 8 is composed of 304 stainless steel pipes, and the pipelines are all connected by metal pipes. The spray pump adopts a pump port equipped with a filter device, and its sealing ring needs to be corrosion-resistant. A 10-micron filter is provided at the solvent outlet of the spray pump, and the parts in contact with the cleaning liquid are all stainless steel.

[0072] Rotary drying: The third main tank body 41 is provided with a rotating tray 6 and a driving mechanism. The rotating tray 6 is driven by a motor 7 to rotate. The pipe 8 is fixed on the adjusting cylinder 13. The distance between the nozzle on the pipe 8 and the parts is controlled by adjusting the stroke of the cylinder 13. The distance can be adjusted adaptively to achieve close-range purging, basically ensuring purging without dead angles, so that some multi-groove parts that are difficult to clean are easier to dry out water vapor and achieve better results. The spraying mechanism sprays on the periphery and cavity of the parts. The wind generated by the fan 43 passes through the heating device and outputs 40°C hot wind into the third main tank body 41. The temperature of 0 to 50°C can be adjusted according to the production process. The third main tank body 41 is ensured to be kept at a certain temperature through continuous hot wind, which accelerates the evaporation of residual water mist after purging, achieves the purpose of rapid drying, reduces the oxidation of the surface of the parts, and timely exhausts the purged moisture. The exhaust ports are respectively arranged in the third main tank body 41 and the inner cavity of the parts. A switch or a water-saving structure is set at the inner cavity to prevent water from being extracted by the fan.

[0073] Manual loading: The operator lifts the parts out through an electric hoist to clean and dry the surface of the parts.

[0074] Embodiment 2: This embodiment is different from Embodiment 1 in that the pressure block 54 includes an active pressure block 541 and seven passive pressure blocks 542. An active air-liquid bag 56 is provided on the slide rail 53 corresponding to the active pressure block 541. Two active air-liquid bags 56 are provided and are respectively located on both sides of the slide rail 53. Each of the slide rails 53 corresponding to the passive pressure blocks 542 is provided with a passive air-liquid bag 57, and the active air-liquid bag 56 is connected to each passive air-liquid bag 57. A force equalizing plate 58 is provided on one side of the active pressure block 541, and the force equalizing plate 58 is connected to the active air-liquid bag 57. The active air-liquid bag 56 is connected, and one side of the passive pressure block 542 is connected to the passive air-liquid bag 57. A plurality of slots 531 are provided on the inner wall of the slide rail 53, and the active pressure block 541 is provided with a spring lock pin engaged with the slot 531. The spring lock pin is purchased from a commercially available spring lock pin, and the shape of the pin head part is adjusted to adapt to the slot 531. The passive pressure block 542 is provided with a pressure-touch lock rod 59 engaged with the slot 531; the pressure-touch lock rod 59 is composed of a gas-liquid telescopic rod and a pressure valve used to connect the gas-liquid telescopic rod with the driven air-liquid bag 57.

[0075] The method of using the above-mentioned equipment is as follows: the method of using this embodiment is basically the same as that of embodiment 1, except that the operator places the parts to be cleaned on the positioning tooling 52 after cleaning, and then pushes the active pressure block 541 to fit the active pressure block 541 with the parts. During this period, the active air-liquid bag 56 of the active pressure block 541 is squeezed by the force equalizing plate 58, so that the air or liquid in the active air-liquid bag 56 is pressed to each driven air-liquid bag 57 through the pipeline, so that the driven air-liquid bag 57 pushes the corresponding driven pressure block 542 to move toward the part, thereby clamping the part at the same time, and continues to push to compress the soft part. Since the pressure of the pressure valve of the pressure-contact locking rod 59 exceeds the limit value, the air-liquid telescopic rod is filled, thereby engaging with the card slot 531, and at the same time opening the spring lock pin to stop the active pressure block 541 and the card slot 531. When the parts need to be removed, the above process can be reversed.

[0076] Embodiment 3: This embodiment is different from Embodiment 1 in that an oil bag 63 for squeezing by means of a driving gear 71 is provided on the tooth rod 62 of the gear ring 61, and the lower end of the oil bag 63 is connected to the rotating connection between the rotating tray 6 and the second main tank body 31 and the third main tank body 41 through a pipeline, and the upper end of the oil bag 63 is connected to an oil storage tank 64 provided on the rotating tray 6 through a pipeline, and the pipelines are all provided with a one-way valve.

[0077] The method of using the above-mentioned equipment is as follows: the method of using this embodiment is basically the same as that of embodiment 1, except that, when the driving gear 71 is engaged with the tooth rod 62, the teeth of the driving gear 71 squeeze the oil bag 63 so that the lubricating oil in the oil bag 63 is squeezed into the pipeline, and then released through the outlet of the pipeline to the rotational connection between the rotating tray 6 and the second main tank body 31 and the third main tank body 41. Subsequently, when the driving gear 71 is disengaged from the tooth rod 62, the oil bag 63 recovers under its own restoring force. At the same time, the oil bag 63 sucks the lubricating oil in the oil storage tank 64 into the oil bag 63; it should be noted that the one-way valve from the oil bag 63 to the pipeline is for one-way delivery to the pipeline, and the one-way valve from the oil storage tank 64 to the oil bag 63 is for one-way delivery to the oil bag 63.
