Description

Technical Field

[0001] The utility model relates to the technical field of the manufacturing of type III hydrogen storage bottle liners, and particularly relates to a vertical cleaning machine for type III hydrogen storage bottle liners after molding. Background Art

[0002] In the hydrogen energy industry, as a key hydrogen storage device, the cleanliness of the liner of a type III hydrogen storage bottle is crucial for hydrogen storage effect and safety. At present, during the manufacturing process of type III hydrogen storage bottle liners, especially after the thread machining process, aluminum chips and cutting fluid often remain inside the liner. The aluminum chips are generated during the thread machining process, and the cutting fluid is used for cooling the thread machining tool. These residues not only affect the cleanliness of the liner but also may pose potential threats to the subsequent hydrogen storage effect and safety performance.

[0003] However, currently on the market, the automatic cleaning equipment for the inner wall of the aluminum liner of type III hydrogen storage bottles after thread machining is basically blank. The traditional cleaning methods mainly rely on manual operation. For example, a spray gun is used to perform high-pressure flushing from one side of the inner liner opening to the other side, or the inner liner is manually placed in an ultrasonic cleaning device for cleaning and then poured. Both of these methods have obvious deficiencies: on the one hand, manual operation has low efficiency and it is difficult to guarantee the cleaning effect; on the other hand, manual loading and unloading and pouring operations increase the labor intensity, which is not conducive to improving production efficiency and product quality.

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

[0005] Therefore, in view of the problems existing in the prior art, it is necessary to propose a new vertical cleaning machine for type III hydrogen storage bottle liners after molding to achieve automatic cleaning, improve the cleaning efficiency and cleanliness, reduce the labor intensity, and ensure product quality and production safety.

[0054] As Figure 4 and Figure 5As shown in the figure, the guiding and positioning cleaning assembly 3 includes a driving servo motor I 3-1 of the guiding structure, a guiding driving toothed belt I 3-2, a linear guide rail slider assembly 3-3, a driving servo motor II 3-4 of the nozzle and the connecting rod, a guiding driving toothed belt II 3-5, a liquid-electric slip ring 3-6, a water-passing main rod 3-7, a guiding member structure 3-8, a guiding seat 3-9, a self-made nozzle 3-10, a nozzle rotation driving motor 3-11, a guiding and positioning structure main body 3-12, and a cleaning part structure 3-13.

[0055] As Figure 6 shown in the figure, the filtering power assembly 4 includes a plunger pump 4-1, a pre-filter 4-2, and a paper tape filter 4-3. The water outlet B of the plunger pump 4-1 is connected to the upper mouth of the inner liner of the type III bottle, and the water suction port A at its rear end is connected to the pre-filter 4-2. The filtered rear end of the paper tape filter 4-3 is connected to the front end of the pre-filter. The water tank of the paper tape filter receives the rinsed liquid and impurities flowing back from the bottom of the type III bottle. The filtered water is pumped out again for subsequent rinsing operations.

[0056] The vertical cleaning machine for the inner liner of type III hydrogen storage cylinders has achieved automation and improved efficiency. Currently, there are mainly two methods for cleaning the threads of aluminum inner liners: a. Relying on manual operation with a high-pressure spray gun directly, which is not only inefficient but also has poor cleaning effect; b. Manual loading and unloading and using an ultrasonic cleaning machine for cleaning, usually in a horizontal position, that is, the bottle body is in a lying position. After ultrasonic cleaning, when manually taking out the bottle, the bottle body still needs to be erected to pour out the residues. The vertical cleaning machine, through an integrated design and a precise control system, has realized the full automation of operations such as product positioning, cleaning, and pouring, significantly improving production efficiency and greatly reducing the intensity of manual operations. The product attitude always remains vertical, and while the water flows from top to bottom for cleaning, all internal residues are flushed out, eliminating the need for subsequent manual pouring operations.

[0057] The specific working process is as follows: First, the inner liner of the type III bottle is vertically sent into the cleaning machine by an external handling device. The bottom nozzle is inserted into the positioning support seat 2-3. The gripper of the external handling device changes to a non-clamping holding posture (the purpose is to assist in maintaining the vertical posture of the inner liner before the upper nozzle of the inner liner is positioned). The servo motor I 3-1 and the servo motor II 3-4 operate simultaneously. After reaching the height set by the system (the guiding structure 3-8 aligns the upper nozzle of the inner liner and the head of the self-made nozzle 3-10 has entered the upper nozzle of the inner liner), they automatically stop. After the gripper of the external handling device is completely released, it exits the working area of the cleaning machine.

[0058] The solenoid valve of the door closing cylinder 2-5 of the cleaning chamber works, and its cylinder rod extends to close the cleaning chamber door 2-6. After the cylinder rod of the door closing cylinder 2-5 extends to the in-place 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, locking the pulley 2-7 into the hook of the door locking connecting rod 2-2, thereby realizing the internal sealing operation of the cleaning chamber assembly 2.

[0059] The filtering power assembly 4 works. The plunger pump 4-1 pumps the filtered water out of the water tank of the paper tape filter 4-3 and conveys it to the water passing main rod 3-7 through the pre-filter 4-2.

[0060] The nozzle rotation drive motor 3-11 starts. The sprocket at the rear end drives the chain to drive the sprocket at the upper end of the water passing main rod 3-7 to rotate. The rotating end of the upper liquid-electric slip ring 3-6, the water passing main rod 3-7, and the self-made nozzle 3-10 follow the rotation action.

[0061] The servo motor II 3-4 works to drive the cleaning part structure 3-13, the water passing main rod 3-7, and the self-made nozzle 3-10 to move downward. When reaching the displacement set by the system, the servo motor II reverses to the starting point of the previous action and then stops. The plunger pump 4-1 of the filtering power assembly 4 stops.

[0062] The solenoid valve of the door locking cylinder 2-1 works in reverse to release the hook of the door locking connecting rod 2-2 from the pulley 2-7, and the solenoid valve of the door closing cylinder 2-5 works in reverse to open the door 2-6.

[0063] The gripper of the external handling equipment enters the working area of the cleaning machine, grasps the inner liner after the cleaning operation and maintains the grasping posture. The servo motor I 3-1 and the servo motor II 3-4 rotate in reverse 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 grasping the inner liner and moving upward, so that the lower bottle mouth of the inner liner is separated from the positioning support seat 2-3 and then withdrawn from the cleaning machine to leave the working area of the cleaning machine, and the whole cleaning operation is completed.

[0064] After the inner liner of the type III hydrogen storage bottle is formed, the vertical cleaning machine precisely controls the walking position driven by the servo motor of the nozzle and the positioning through the internal program of the PLC, and cooperates with the filtering and pumping operations of the paper tape filter and the screw pump, and communicates the position information with the external gripper. The product range that the equipment can adapt to only by simply replacing the upper and lower bottle mouth positioning blocks is as follows: the diameter is φ200mm-φ420mm, and the length is 800-2200mm. Formulas for products of different specifications are set in the equipment control system. One formula corresponds to the position parameters of each position in the equipment for a set of products. Each product only needs to set the parameters once, and the number can be directly called when producing again next time.
