Description

Technical Field

[0001] The utility model relates to the technical field of gas filters, in particular to a gas filter with a leakage alarm function. Background Art

[0002] Gas filter is an indispensable device on the pipeline for conveying medium. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, positioning valve or other equipment to remove impurities in the medium, so as to protect the normal use of valves and equipment and reduce equipment maintenance costs.

[0003] A known authorized invention (publication number: CN217173637U) discloses a gas filter, which includes a body and a filter element. The body is provided with a filter cavity, an air inlet and an air outlet which are interconnected. The filter element is arranged in the filter cavity, and the air inlet and the air outlet are located on both sides of the filter element. The filter element includes an outer shell, an inner shell and a filler. The filler is arranged in the inner shell, and the inner shell is arranged in the outer shell. The outer periphery of the outer shell fits the inner wall of the filter cavity, and both the outer shell and the inner shell are provided with filter holes. The filler can be cotton wool. When in use, the gas enters the filter cavity from the air inlet, and after triple filtration by the outer shell, inner shell and filler of the filter element, the gas is discharged from the air outlet, so as to achieve the use of the outer shell and inner shell to block particulate impurities, and use fillers such as cotton wool to block colloidal impurities, thereby effectively improving the filtering effect of the gas filter;

[0004] Although the device uses an outer shell and an inner shell to block particulate impurities when in use, and uses fillers such as cotton wool to block colloidal impurities, thereby effectively improving the filtering effect of the gas filter, the device lacks a leakage alarm function. In actual use, due to the influence of various factors, such as filter aging, damage or improper installation, gas leakage may occur. If the leakage problem cannot be discovered and handled in time, it will not only waste resources, but also may pose a threat to the environment and personal safety. Therefore, we propose a gas filter with a leakage alarm function to solve the above problem. Utility Model Content

During the use of the gas filter body 1, the integrated sensor 2 is used to monitor the flow rate, pressure and other key information of the gas in real time. Parameters, once the integrated sensor 2 detects an abnormality, such as gas leakage or abnormal flow, it will immediately transmit the signal to the PLC processor 5 in the control box 4 for processing. After receiving the signal from the integrated sensor 2, the PLC processor 5 will quickly process and analyze the data to determine whether it is necessary to trigger an alarm. If the PLC processor 5 confirms that there is an abnormality, it will send an instruction to the actuator 6. After receiving the instruction, the actuator 6 will drive the electric push rod 7 to work. The electric push rod 7 drives the first copper block 8 to contact the second copper block 9. At this time, the first copper block 8, the second copper block 9, the battery 11 and the alarm 10 form a circuit. The alarm 10 will emit a high-decibel sound and obvious flashes to remind the operator to pay attention to handling it. Once the gas filter body 1 leaks or other abnormal conditions occur, an alarm can be quickly issued, thereby ensuring the safety and reliability of the gas supply system.

[0028] like Figure 3 As shown, in some embodiments, a plurality of heat dissipation holes 13 are provided on the inner walls on both sides of the control box 4. The provision of the heat dissipation holes 13 plays a role in heat dissipation.

[0029] like Figure 4 As shown, in some embodiments, the integrated sensor 2, the PLC processor 5, the actuator 6, the electric push rod 7 and the touch screen 12 are electrically connected through conductive wires, and the setting of the electric push rod 7 realizes automation.

[0030] like Figure 4As shown, in some embodiments, the negative pole of the battery 11 is electrically connected to the first copper block 8 through a conductive line, the alarm 10 is electrically connected to the second copper block 9 through a conductive line, and the positive pole of the battery 11 is electrically connected to the alarm 10 through a conductive line. The battery 11, the alarm 10, the second copper block 9 and the first copper block 8 constitute a circuit in sequence, and the setting of the battery 11 plays a role in power supply.

The setting of the U-shaped block 14 plays a supporting role.

[0032] like Figure 5 As shown, in some embodiments, a clamping rod 17 is fixedly connected to one side of the moving block 16, and a spring 18 is welded between the other side of the moving block 16 and the inner wall of one side of the U-shaped block 14. The spring 18 is movably mounted on the positioning rod 15. The setting of the positioning rod 15 plays a positioning role.

[0033] like Figure 5 As shown, in some embodiments, a fixing block 20 is fixedly connected to the bottom of the box cover 19, and a card slot 21 is provided on both sides of the fixing block 20. The card slot 21 is clamped with the corresponding clamp rod 17, and the setting of the fixing block 20 plays a connecting role.

[0034] The working principle or structural principle is that when in use, during the use of the gas filter body 1, the key parameters such as the flow rate and pressure of the gas are monitored in real time through the integrated sensor 2. Once the integrated sensor 2 detects an abnormality, such as gas leakage or abnormal flow rate, it will immediately transmit the signal to the PLC processor 5 in the control box 4 for processing. After receiving the signal from the integrated sensor 2, the PLC processor 5 will quickly process and analyze the data to determine whether it is necessary to trigger an alarm. If the PLC processor 5 confirms that there is an abnormality, it will send an instruction to the actuator 6. After receiving the instruction, the actuator 6 will drive the electric push rod 7 to work, and the electric push rod 7 drives the first copper block 8 to contact the second copper block 9. At this time, the first copper block 8, the second copper block 9, the battery 11 and the alarm 10 A loop is formed, and the alarm 10 will emit a high-decibel sound and obvious flashes to remind the operator to pay attention to handling it. Once the gas filter body 1 leaks or other abnormal conditions occur, an alarm can be quickly sounded, thereby ensuring the safety and reliability of the gas supply system. When it is necessary to repair the electronic components in the control box 4, the two moving blocks 16 are moved away from each other. The moving blocks 16 slide on the positioning rods 15. The moving blocks 16 compress the corresponding springs 18 during the movement. At the same time, the moving blocks 16 drive the corresponding clamping rods 17 to be clamped with the clamping slots 21. Then, the box cover 19 is rotated to open it, which is convenient for repairing the internal electronic components. The setting of the heat dissipation holes 13 allows the heat generated in the control box 4 to be dissipated in time.
