Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas flow monitoring, in particular to a double-roller end cover sealing element and a gas leakage monitoring device for a side cover airbag. Background Art
[0002] For the double-roll pulp washer, the sealing of the double-roll end cover and side cover is very important. This is because during the operation of the double-roll pulp washer, the slurry circulates between the double rollers. If the end cover and side cover are not sealed tightly, the slurry is easy to leak from the gap, which will not only cause material loss, but also pollute the environment. At the same time, the leaked slurry may also corrode other parts of the equipment, causing equipment damage and increasing maintenance costs. In addition, poor sealing will also affect the overall performance of the double-roll pulp washer and reduce production efficiency. Therefore, ensuring the sealing of the double-roll end cover and side cover is a key measure to ensure the normal operation of the double-roll pulp washer, improve production efficiency and protect the environment.
[0003] In a double-roll pulp washer, the end cover is usually sealed with a seal, while the side cover is sealed with an air bag. The existing sealing mechanism is to provide a stable air source pressure for the end cover seal and the side cover air bag, and rely on the air pressure to achieve effective sealing. At the same time, the pressure status is monitored in real time with the help of a pressure gauge. Once the pressure gauge shows a drop in pressure, it indicates that there is a leak, which requires timely inspection and maintenance.
[0004] However, the amount of air leakage of the double-roller end cover seal and the side cover airbag cannot be intuitively determined solely by the pressure change displayed by the pressure gauge, which makes it difficult to accurately assess the degree of wear of the seal and the airbag, and further to determine whether repair or replacement is required. Summary of the invention
[0005] Aiming at the problem that it is difficult to accurately evaluate the degree of wear of double-roller end cover seals and side cover airbags by monitoring the air leakage of double-roller end cover seals and side cover airbags through pressure gauges, the utility model provides an air leakage monitoring device for double-roller end cover seals and side cover airbags, which can intuitively monitor the air leakage of double-roller end cover seals and side cover airbags and easily evaluate the degree of wear of seals and airbags.
[0006] In order to solve the above problems, the technical solution adopted by the utility model is a leakage monitoring device for double-roller end cover seals and side cover airbags, including an air intake pipeline, the ends of which are respectively connected to the end cover sealing pipeline and the side cover sealing pipeline, and gas flow meters are installed on the end cover sealing pipeline and the side cover sealing pipeline. When the double-roller end cover seal and the side cover airbag are in good sealing condition, no gas will flow in the end cover sealing pipeline and the side cover sealing pipeline; however, once the double-roller end cover seal or the side cover airbag is deflated, gas will flow in the corresponding end cover sealing pipeline or the side cover sealing pipeline, and the gas flow meter will accurately capture and measure the gas flow. Through this intuitive numerical value, the staff can quickly evaluate the wear condition of the double-roller end cover seal or the side cover airbag, and then accurately judge whether it needs to be replaced, to ensure the safe and stable operation of the equipment.
[0007] Preferably, the gas flow meter is configured as a gas rotor flow meter. Whether it is a small flow or a large flow, the gas rotor flow meter can achieve accurate measurement. In addition, the gas rotor flow meter can directly read the flow value, which is convenient and quick to use.
[0008] Preferably, pressure gauges are installed on both the end cover sealing pipeline and the side cover sealing pipeline. When the end cover sealing pipeline or the side cover sealing pipeline is deflated, the indication of the pressure gauge will drop significantly, and this change can effectively remind the staff of the deflation phenomenon, so as to facilitate timely taking corresponding measures.
[0009] Preferably, photoelectric sensors are installed inside the end cover sealing pipeline and the side cover sealing pipeline, and the transmitting end of the photoelectric sensor is facing the gas flow meter. When a gas leak occurs and gas flows inside the end cover sealing pipeline and the side cover sealing pipeline, this airflow will blow the gas flow meter away from its original position, thereby causing the photoelectric sensor to be unable to detect the gas flow meter. Once the photoelectric sensor detects this abnormal situation, it will immediately sound an alarm and promptly notify the staff of the occurrence of the gas leak, so that necessary measures can be taken quickly to deal with it and ensure the normal operation of the equipment and production safety.
[0010] Preferably, a solenoid valve is installed on the side cover sealing pipeline. When the pressurization stops, the gas in the side cover airbag will be automatically discharged through the solenoid valve. This design effectively avoids the side cover airbag being damaged due to the staff forgetting to manually release the pressure and directly opening the side cover, thereby ensuring the safety and stability of the equipment.
[0011] Preferably, a main valve is installed on the air inlet pipeline, which has the function of regulating the air source pressure to ensure that the air pressure is stably controlled within a required range.
[0012] It can be seen from the above technical solutions that the advantage of the utility model is that when the double-roller end cover seal and the side cover airbag are in a good sealing state, the gas in the end cover sealing pipeline and the side cover sealing pipeline will be in a static state. However, once the end cover seal or the side cover airbag is deflated, gas flow will appear in the corresponding end cover sealing pipeline or the side cover sealing pipeline. At this time, the gas flowmeter will quickly capture this change and accurately measure the gas flow. At the same time, the photoelectric sensor will immediately sound an alarm because it cannot detect the gas flowmeter. In summary, through the intuitive numerical values provided by the gas flowmeter, the staff of this device can quickly evaluate the wear of the double-roller end cover seal or the side cover airbag, so as to accurately determine whether replacement is needed to ensure the stable operation and safety of the equipment.

[0017] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0018] A double-roller end cover seal and a side cover airbag air leakage monitoring device comprises an air intake pipeline 1, the head end of which is connected to an air pump. A main valve 4 is installed on the air intake pipeline 1, and the main valve 4 can adjust the gas flow rate and thus adjust the gas source pressure. The ends of the air intake pipeline 1 are respectively connected to an end cover sealing pipeline 2 and a side cover sealing pipeline 3, the end of the end cover sealing pipeline 2 is connected to a double-roller end cover seal 10, and the end of the side cover sealing pipeline 3 is connected to a side cover airbag 8.
[0019] like Figure 1 As shown, in this specific embodiment, there are four end cover sealing pipelines 2, which are connected to the two ends of the two rollers respectively, to ensure that the end cover of each roller can be effectively sealed. A pressure gauge 6 is installed on the end cover sealing pipeline 2, which can measure the internal air pressure of the end cover sealing pipeline 2. When the end cover sealing pipeline 2 is deflated, the reading of the pressure gauge 6 will drop significantly, prompting the staff to replace the double roller end cover seal 10. A gas flow meter 7 is also installed on the end cover sealing pipeline 2. According to the gas flow direction, the gas flow meter 7 is located behind the pressure gauge 6. In this embodiment, the gas flow meter 7 adopts a gas rotor flow meter, which can monitor the gas flow inside the end cover sealing pipeline 2. When the end cover sealing pipeline 2 is deflated, the gas rotor flow meter can monitor the deflated amount and directly display it, which is convenient for the staff to read and can help the staff to quickly determine whether the double roller end cover seal 10 needs to be replaced.
[0020] A photoelectric sensor 9 is installed inside the end cap sealing pipeline 2. According to the gas flow direction, the photoelectric sensor 9 is located behind the gas flow meter 7, and the transmitting end of the photoelectric sensor 9 is facing the gas flow meter 7. When the end cap sealing pipeline 2 is deflated, the gas flow meter 7 will be blown away by the airflow, causing it to deviate from its original position. The transmitting end of the photoelectric sensor 9 will not sense the gas flow meter 7, and the electrical signal of the photoelectric sensor 9 will change, and an alarm will be sounded to remind the staff that the double-roller end cap seal 10 here is deflated.
[0021] In this specific embodiment, the side cover sealing pipeline 3 is provided with one. A solenoid valve 5 is installed on the side cover sealing pipeline 3. When the device stops working, the high-pressure gas inside the side cover airbag 8 will be automatically discharged from the solenoid valve 5. The side cover sealing pipeline 3 is also equipped with a pressure gauge 6. According to the gas flow direction, the pressure gauge 6 is located behind the solenoid valve 5. The pressure gauge 6 can measure the internal air pressure of the side cover sealing pipeline 3. When the side cover sealing pipeline 3 is deflated, the reading of the pressure gauge 6 will drop significantly, prompting the staff that the side cover airbag 8 may need to be replaced. A gas flow meter 7 is also installed on the side cover sealing pipeline 3. According to the gas flow direction, the gas flow meter 7 is located behind the pressure gauge 6. In this embodiment, the gas flow meter 7 adopts a gas rotor flow meter. The gas rotor flow meter can monitor the gas flow inside the side cover sealing pipeline 3. When the side cover sealing pipeline 3 is deflated, the gas rotor flow meter can monitor the deflated amount and directly display it, which is convenient for the staff to read and can help the staff quickly determine whether the side cover airbag 8 needs to be replaced.
[0022] A photoelectric sensor 9 is installed inside the side cover sealing pipeline 3. According to the gas flow direction, the photoelectric sensor 9 is located behind the gas flow meter 7, and the transmitting end of the photoelectric sensor 9 is facing the gas flow meter 7. When the side cover sealing pipeline 3 is deflated, the gas flow meter 7 will be blown away by the airflow, causing it to deviate from its original position. The transmitting end of the photoelectric sensor 9 will not sense the gas flow meter 7, and the electrical signal of the photoelectric sensor 9 will change, and an alarm will be sounded to remind the staff that the side cover airbag 8 here is deflated.
[0023] The specific use process of the utility model is as follows: first, start the main valve 4 and the air pump to inject gas into the air inlet pipeline 1. The gas is then diverted to the end cover sealing pipeline 2 and the side cover sealing pipeline 3. In the end cover sealing pipeline 2, the gas flows through the pressure gauge 6, the gas flow meter 7 and the photoelectric sensor 9 in sequence, and finally acts on the double-roller end cover seal 10 to achieve pressurized sealing thereof, ensuring that the gaps at both ends of the double rollers are effectively closed. Once the end cover seal 10 is worn and causes gas leakage, the gas in the end cover sealing pipeline 2 will begin to flow, the gas flow meter 7 will be blown, and the photoelectric sensor 9 will immediately capture the signal change and upload it to the control system, triggering an alarm to remind the staff. At the same time, the reading of the pressure gauge 6 drops, and the gas flow meter 7 records the amount of gas leakage, based on which the staff determines whether the end cover seal 10 needs to be replaced.
[0024] On the other hand, the gas in the side cover sealing pipeline 3 passes through the solenoid valve 5, the pressure gauge 6, the gas flow meter 7 and the photoelectric sensor 9 in turn, and finally inflates the side cover airbag 8, causing it to expand and fit tightly to the side cover gap to prevent the slurry from leaking out. If the side cover airbag 8 is worn and causes gas leakage, it will also cause the gas in the side cover sealing pipeline 3 to flow, the gas flow meter 7 will be activated, the signal of the photoelectric sensor 9 will change, and the control system will be triggered to sound an alarm. At this time, the reading of the pressure gauge 6 will also drop, and the gas flow meter 7 will record the deflation situation, providing a basis for the staff to judge whether the side cover airbag 8 needs to be replaced.
[0025] In the case where pressurized sealing is not required, the air pump can be turned off. At this time, the high-pressure gas in the side cover airbag 8 will pass through the photoelectric sensor 9, the gas flow meter 7 and the pressure gauge 6 in sequence, and finally be automatically discharged through the solenoid valve 5 to ensure the safe and stable operation of the system.
[0026] It can be seen from the above embodiments that the beneficial effect of the utility model is that when the double-roller end cover seal and the side cover airbag are in a good sealing state, the gas in the end cover sealing pipeline and the side cover sealing pipeline will be in a static state. However, once the end cover seal or the side cover airbag is deflated, gas flow will appear in the corresponding end cover sealing pipeline or the side cover sealing pipeline. At this time, the gas flowmeter will quickly capture this change and accurately measure the gas flow. At the same time, the photoelectric sensor will immediately sound an alarm because it cannot detect the gas flowmeter. In summary, through the intuitive numerical values provided by the gas flowmeter, the staff of this device can quickly evaluate the wear of the double-roller end cover seal or the side cover airbag, so as to accurately determine whether replacement is needed to ensure the stable operation and safety of the equipment.
