Description

Technical Field

[0001] The invention relates to the technical field of manufacturing inner liner of a type III hydrogen storage bottle, and in particular to a vertical cleaning machine for the inner liner of a type III hydrogen storage bottle after molding. Background Art

[0002] In the hydrogen energy industry, Type III hydrogen storage bottles are key hydrogen storage devices, and the cleanliness of their inner tanks is crucial to the hydrogen storage effect and safety. At present, during the manufacturing process of the inner tank of Type III hydrogen storage bottles, especially after the thread processing, aluminum chips and cutting fluid often remain inside the inner tank. Aluminum chips are generated during the thread processing process, and cutting fluid is used to cool the thread processing tools. These residues not only affect the cleanliness of the inner tank, but may also pose a potential threat to the subsequent hydrogen storage effect and safety performance.

[0003] However, there is still a lack of automatic cleaning equipment for the inner wall of the aluminum inner tank of Type III hydrogen storage bottles after thread processing in the current market. Traditional cleaning methods mainly rely on manual operation, such as using a spray gun to perform high-pressure flushing from one side of the inner tank opening to the other side, or manually placing the inner tank in an ultrasonic cleaning device for cleaning before dumping. Both methods have obvious shortcomings: on the one hand, manual operation is inefficient and the cleaning effect is difficult to guarantee; on the other hand, manual loading and unloading and dumping operations increase labor intensity, which is not conducive to improving production efficiency and product quality.

[0004] Specifically, although the high-pressure washing method using a spray gun can wash away some residues, it is often difficult to achieve a thorough cleaning effect, and splashing is easy to occur during the operation, posing a threat to the safety of operators. Although the cleaning method using an ultrasonic cleaning machine has a better cleaning effect, it usually requires manual loading and unloading and dumping operations, which not only increases labor intensity, but may also cause damage to the product during the cleaning process or secondary contamination.

[0005] Therefore, in view of the problems existing in the prior art, it is necessary to propose a new type of vertical cleaning machine for the post-molding inner liner of Type III hydrogen storage bottle to realize automated cleaning, improve cleaning efficiency and cleanliness, while reducing labor intensity and ensuring product quality and production safety.

[0034] The vertical cleaning machine has significant advantages in solving the problems of low automation, low efficiency, and time-consuming and labor-intensive manual cleaning in the current production process. Example

[0035] like Figure 1 As shown, the vertical cleaning machine for the inner liner of a type III hydrogen storage bottle after molding includes a frame 1, a cleaning chamber assembly 2, a guide positioning cleaning assembly 3 and a filtering power assembly 4.

[0036] The cleaning chamber assembly 2 , the guiding and positioning cleaning assembly 3 and the filtering power assembly 4 are fixedly mounted on the frame 1 .

[0037] The cleaning chamber assembly 2 is used to position and load the inner liner of the Type III hydrogen storage bottle and to form a closed cavity that is splash-proof.

[0038] The guiding and positioning cleaning component 3 is used to spray water to clean the inner wall of the product, and the nozzle and its connecting rod can rotate and rise and fall freely within a limited size range.

[0039] like Figure 2 and Figure 3 As shown, the cleaning bin assembly 2 includes a bin door locking cylinder 2-1, a bin door locking connecting rod 2-2, a positioning support seat 2-3, a base 2-4, a bin door closing cylinder 2-5, a bin door 2-6, a pulley 2-7 and a cleaning bin structure 2-8; the base 2-4 is fixedly connected to the inner bottom surface of the cleaning bin structure 2-8, the bottom of the positioning support seat 2-3 is fixedly mounted on the upper plane of the base 2-4, and the side of the bin door 2-6 is fixedly mounted on the side of the cleaning bin structure 2-8 by a hinge. The main body end and output shaft end of the door closing cylinder 2-5 are respectively installed in the middle and lower parts of the cleaning bin structure 2-8 and the bin door 2-6 for opening and closing the bin door. The pulley 2-7 is fixedly installed on the side of the bin door 2-6 to provide a sliding guide for the locking hook when the bin door is locked. The side of the bin door locking link 2-2 is fixedly installed on the side of the cleaning bin structure 2-8 and its bottom is fixedly connected to the output shaft end of the door closing cylinder 2-5. The main body of the door closing cylinder 2-5 is fixedly installed on the frame 1.

[0040] like Figure 4 and Figure 5As shown, the guide positioning cleaning component 3 includes a driving servo motor I3-1 for the guide structure, a guide driving toothed belt I3-2, a linear guide slider assembly 3-3, a driving servo motor II3-4 for the nozzle and the connecting rod, a guide driving toothed belt II3-5, a hydraulic slip ring 3-6, a water-passing main rod 3-7, a guide structure 3-8, a guide seat 3-9, a self-made nozzle 3-10, a nozzle rotation driving motor 3-11, a guide positioning structure body 3-12 and a cleaning part structure 3-13, the output shaft ends of the servo motor I3-1 and the servo motor II3-4 are fixedly installed on the lower end of the guide positioning structure body 3-12, the guide rail of the linear guide slider assembly 3-3 is fixedly installed on the front end of the positioning structure body 3-12, the four groups of sliders of the linear guide slider assembly 3-3 are evenly divided into two parts and respectively connected to the guide structure 3-8 and the cleaning part structure 3-13, and the two toothed wheels of the guide driving toothed belt I3-2 are divided into They are respectively installed on the output shaft end of the servo motor I 3-1 and the mounting plate of the guide positioning structure 3-12. The two toothed wheels of the guide drive toothed belt II 3-5 are respectively installed on the output shaft end of the servo motor II 3-4 and the mounting plate of the cleaning part structure 3-13. The guide seat 3-9 is fixedly connected to the bottom of the guide positioning structure body 3-12 by bolts, and has a diameter slightly larger than the homemade nozzle 1-10 in the middle.

The sprocket connected to the upper end of the water-passing main rod 3-7 is driven by a chain to finally make the homemade nozzle 3-10 form a rotating posture.

[0041] like Figure 6 As shown, the filtering power assembly 4 includes a plunger pump 4-1, a pre-filter 4-2 and a paper belt filter 4-3; the water outlet B of the plunger pump 4-1 is connected to the upper opening of the inner tank of the type III bottle, and the water suction port A at its rear end is connected to the pre-filter 4-2. The filtering rear end of the paper belt filter 4-3 is connected to the front end of the pre-filter. The water tank of the paper belt filter receives the flushed liquid and impurities flowing back from the bottom of the type III bottle, and the filtered water is pumped out again for subsequent flushing operations.

[0042] The vertical cleaning machine for the post-molding inner liner of the Type III hydrogen storage bottle has achieved automation and improved efficiency: Currently, there are two main ways to clean the aluminum inner liner after thread processing: a: relying on manual direct high-pressure spray gun operation, which is not only inefficient but also has poor cleaning effect; b: manual loading and unloading using an ultrasonic cleaning machine for cleaning, generally in a horizontal position, that is, the bottle body is in a lying position. After ultrasonic cleaning, it is necessary to manually take it out and stand the bottle body up to dump the residue. The vertical cleaning machine has achieved full automation from product positioning, cleaning, dumping and other operations through integrated design and precise control system, which significantly improves production efficiency and greatly reduces the intensity of manual work. The product posture is always kept vertical, and the water flow cleans from top to bottom while completing all internal residue flushing, without the need for manual dumping operations later.

[0043] The specific working process is as follows: first, the type III bottle liner is vertically sent into the cleaning machine through the external handling equipment, and the bottom bottle mouth is inserted into the positioning support seat 2-3. The gripper of the external handling equipment changes to a non-clamping holding posture (the purpose is to assist in maintaining the vertical posture of the liner before the upper bottle mouth of the liner is positioned). The servo motor I3-1 and the servo motor II3-4 operate at the same time. After reaching the height set by the system (the guide structure 3-8 guides the upper bottle mouth of the liner and the head of the self-made nozzle 3-10 has entered the upper bottle mouth of the liner), it stops automatically, and the gripper of the external handling equipment is completely released and then exits the working area of ​​the cleaning machine.

[0044] The solenoid valve of the door closing cylinder 2-5 works, and its cylinder rod extends to close the door 2-6. After the cylinder rod of the door closing cylinder 2-5 is extended to the right position, the solenoid valve of the door locking cylinder 2-1 works, and its cylinder rod extends to drive the door locking connecting rod 2-2 to swing downward to lock the pulley 2-7 into the swing hook of the door locking connecting rod 2-2, thereby realizing the internal sealing operation of the cleaning bin assembly 2.

[0045] The filtering power assembly 4 works, and the plunger pump 4-1 pumps the filtered water out of the water tank of the paper belt filter 4-3 and transports it to the water main rod 3-7 through the pre-filter 4-2.

[0046] The nozzle rotation drive motor 3-11 is started, and the sprocket drive chain at its rear end drives the sprocket at the upper end of the water-passing main rod 3-7 to rotate, and the rotating end of the upper hydraulic-electric slip ring 3-6, the water-passing main rod 3-7, and the self-made nozzle 3-10 follow the rotation action.

[0047] The servo motor II 3-4 drives the cleaning part structure 3-13, the water main rod 3-7, and the self-made nozzle 3-10 to move downward. When the system set displacement is reached, the servo motor II moves in the opposite direction to the starting point of the previous action and then stops, and the plunger pump 4-1 of the filtering power assembly 4 stops.

[0048] The solenoid valve of the door locking cylinder 2-1 works in reverse to make the swing hook of the door locking connecting rod 2-2 release the pulley 2-7, and the solenoid valve of the door closing cylinder 2-5 works in reverse to open the door 2-6.

[0049] The external handling equipment gripper enters the working area of ​​the cleaning machine to grip the inner liner after the cleaning operation and maintains the gripping posture. The servo motor I 3-1 and the servo motor II 3-4 rotate in the opposite direction at the same time, so that the guide structure 3-8 and the self-made nozzle 3-10 are separated from the upper bottle mouth of the inner liner. The external handling equipment keeps gripping the inner liner and moves it upward to make the lower bottle mouth of the inner liner separate from the positioning support seat 2-3 and then withdraw it to the outside of the cleaning machine and leave the working area of ​​the cleaning machine. The entire cleaning operation is completed.

[0050] The vertical cleaning machine for the type III hydrogen storage bottle liner after molding uses the PLC internal program to accurately control the travel position of the nozzle and the positioning servo motor drive, and cooperates with the filtering and pumping operations of the paper belt filter and the screw pump, and communicates position information with the external gripper. The equipment can adapt to the following product range by simply replacing the upper and lower bottle mouth positioning blocks: diameter φ200mm-φ420mm, length 800-2200mm, and set recipes for products of different specifications in the equipment control system. One recipe corresponds to each position parameter of a set of products in the equipment. Each product only needs to set the parameters once, and the number can be directly called during the next production.
