[0022] Example

[0023] Figure 1 This is a schematic structural diagram of an explosion-proof alarm filter embodiment of the present invention. Figure 2The present invention provides a shell structure schematic diagram of an explosion-proof alarm filter embodiment of the present invention. As shown in the figure, the present invention provides an explosion-proof alarm filter, including a shell 1, a filter element 2 arranged inside the shell 1, a support mechanism 3 arranged below the filter element 2, a positioning mechanism 4 arranged on both sides of the support mechanism 3, an alarm mechanism 5 arranged below the positioning mechanism 4, and a rear box cover 6 arranged below the alarm mechanism 5, and the rear box cover 6 is fixed to the bottom end of the shell 1; a mounting column 7 is arranged at the central axis of the shell 1, a horizontal plate 8 is arranged at the bottom end of the mounting column 7, a column 9 is arranged at the central axis below the horizontal plate 8, and the bottom end of the column 9 is connected to the alarm mechanism 5. The upper end surface of the mounting column 7 is higher than the upper end surface of the shell 1, and a connecting thread is arranged on the outer wall of the mounting column 7. The support mechanism 3 includes a support spring 31 sleeved on the bottom end of the mounting column 7 and a drag shell 32 arranged above the support spring 31, and both ends of the upper surface of the drag shell 32 are in contact with the filter element 2. A rubber pad 33 is provided at the connection between the drag shell 32 and the support spring 31, and a rubber ring 34 is provided at the connection between the outer circumference of the drag shell 32 and the filter element 2. The alarm mechanism 5 includes a circuit board 51 arranged below the horizontal plate 8 and an alarm 52 connected to the circuit board 15, and the alarm 52 is fixed at the center of the rear box cover 6. The alarm 52 is connected to the column 9, and the alarm has two alarm modes: real voice prompt alarm and buzzer prompt alarm. The filter element of the present invention can filter out solid particles and mechanical impurities such as rust and dust of a specific size range in the oil product, thereby reducing the wear on the flow meter, solenoid valve and automobile engine of the fuel dispenser. When the oil product contains free water, the filter element can quickly absorb the free water, and at the same time significantly reduce the refueling speed of the fuel dispenser, which serves to warn and remind the refueling operator. After the filter element absorbs the free water, the weight will increase, and it will never be transmitted to the alarm through the spring and the column, and the operator is reminded to replace the filter element through the alarm. When replacing the filter element, first take protective measures, put out the fire extinguisher and the guardrail, and then prepare the tools, filter element and oil box needed to replace the filter element; cut off the shut-off valve at the bottom of the oil machine, and turn off the power of the self-priming pump refueling machine; conduct an inspection, refuel, and check whether the shut-off valve is effective to avoid oil spraying due to invalid valve; use a 22# ratchet wrench tool to remove the top bolts, take out the old filter element, take out the original oil seal and original gasket, replace with a thickened gasket, replace with a skeleton oil seal, and pay attention to the presence of the sealing ring, replace with a water-detectable filter element, and ensure the installation of two sealing rings.

Figure 4This is a schematic diagram of the positioning needle housing structure of an explosion-proof alarm filter embodiment of the present invention. As shown in the figure, the positioning mechanism 4 is set to two, and the positioning mechanism 4 includes a positioning needle housing 41, a positioning needle 42 arranged inside the positioning needle housing 41, a positioning spring 43 arranged at the bottom end of the positioning needle 42, and a screw 44 arranged at the bottom end of the positioning spring 43.
