[0002] In the field of petroleum and chemical industry, tank trucks are often used to transport products. Due to changes in the temperature inside the tank or during the process of refueling and unloading the tank, the air pressure inside the tank changes significantly. At this time, a breathing valve is needed to balance the positive and negative pressure generated inside the tank of the tank truck to ensure the normal operation of the tank. When performing rust removal and maintenance work on the tank body of the tank truck, the rusted parts need to be polished, leaving more iron filings around the tank truck. At the same time, the coming and going of cars in the parking lot can easily raise iron filings and other dust into the air. Conventional breathing valves may inhale iron filings and dust into the tank during the inhalation process. As the use time increases, the iron filings and dust accumulated in the tank increase, polluting the oil products. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0018] The following will describe the specific embodiments of the present utility model in conjunction with the drawings:
[0019] As shown Figures 1 to 3 in the figure, a dust-proof structure applicable to the breather valve of an oil tanker includes a valve body 1. A detachable top cover 16 is provided at the top of the valve body 1. The detachable top cover 16 facilitates the maintenance of the components inside the valve body 1 or the cleaning of the inner wall of the valve body 1. The bottom of the valve body 1 is detachably connected to the oil tanker through a flange, which facilitates the installation or disassembly of the breather valve as a whole on the oil tanker. A negative pressure chamber 12 is provided in the upper part of the valve body 1, and a positive pressure chamber 11 is provided in the lower part. The negative pressure chamber 12 and the positive pressure chamber 11 are interconnected through a connecting chamber 13. An inhalation valve 14 is provided in the negative pressure chamber 12, and an exhalation valve 15 is provided in the positive pressure chamber 11. When the air pressure in the tank body is relatively high, the inhalation valve 14 closes and the exhalation valve 15 opens, and the tank body discharges the excess gas, so that the internal air pressure of the tank body returns to the normal state. When the air pressure in the tank body is relatively low, the inhalation valve 14 opens and the exhalation valve 15 closes, and the tank body absorbs a part of the gas from the outside, so that the internal air pressure of the tank body returns to the normal state.
[0020] The valve body 1 is provided with an L-shaped pipe 4 corresponding to the inhalation valve 14. One end of the L-shaped pipe 4 is communicated with the inhalation valve 14, and a coarse filtration mechanism 3 is provided at the other end. An electromagnetic component 2 is provided at one end of the L-shaped pipe 4 close to the inhalation valve 14. Through the double filtration of the electromagnetic component 2 and the coarse filtration mechanism 3, iron filings or other dust are isolated outside the valve body 1. Thereby improving the dust-proof effect of the breather valve. Under the guiding action of the L-shaped pipe 4, the iron filings and other dust particles inside the L-shaped pipe 4 are discharged from the L-shaped pipe 4.
[0021] The valve body 1 is provided with a first groove 141 that cooperates with the bottom of the inhalation valve 14, and the top cover 16 is provided with a cavity 161 that cooperates with the top of the inhalation valve 14. A spring 142 is provided in the cavity 161. One end of the spring 142 contacts the inhalation valve 14, and the other end contacts the inner top wall of the cavity 161. When the breather valve inhales, the inhalation valve 14 moves upward, leaving the first groove 141 and compressing the spring 142. After the air pressure in the tank returns to balance, under the action of the resilience of the spring 142, the inhalation valve 14 returns to the first groove 141.
[0022] The valve body 1 is provided with a second groove 151 that cooperates with the exhalation valve 15. One side of the exhalation valve 15 is rotatably connected to the side wall of the second groove 151 through a spring rotating shaft. When the breather valve exhales gas, under the action of the air pressure in the tank, the exhalation valve 15 rotates around the spring rotating shaft, and the excess gas in the oil tank is discharged. After the air pressure in the oil tank returns to normal, the spring rotating shaft automatically makes the exhalation valve 15 embed into the second groove 151.
[0023] The L-shaped tube 4 is provided with a chute for the electromagnetic assembly 2 to pass through. The electromagnetic assembly 2 includes an integrated magnetization plate 21 and an electromagnet 23. The electromagnet 23 is the source of the magnetic force of the magnetization plate 21. The side surface of the magnetization plate 21 is attached to the inner wall of the L-shaped tube 4. When the electromagnetic assembly 2 is assembled in the chute, there is a large frictional force between the side surface and the chute, and the electromagnetic assembly 2 is stably clamped in the chute through the frictional force. The magnetization plate 21 is of a double-layer structure, and the positions of the air holes 211 on both sides of the magnetization plate 21 are staggered from each other. When the air flow passes through the air holes 211, the iron filings are adsorbed on the magnetization plate 21 under the action of the magnetic force. The staggered air holes 211 facilitate ventilation while increasing the contact probability between the iron powder and the magnetization plate 21. The side surface of the magnetization plate 21 is provided with a side opening 212, through which it is convenient to discharge the iron powder accumulated in the magnetization plate 21. An explosion-proof shell 22 is provided outside the electromagnet 23, and a switch 221 for controlling the circuit of the electromagnet 23 is provided on the explosion-proof shell 22. The explosion-proof shell 22 can improve the safety performance when the electromagnet 23 is in use. By controlling the switch 221 to change the magnetism of the electromagnet 23, when the circuit of the electromagnet 23 is disconnected, the electromagnet 23 and the magnetization plate 21 lose their magnetism, and the iron powder on the magnetization plate 21 falls below the L-shaped tube 4.
[0024] The coarse filtration mechanism 3 includes a pressing ring 31 and a dust-proof cotton 32. A positioning groove 33 corresponding to the coarse filtration mechanism 3 is provided at the end of the L-shaped tube 4. The dust-proof cotton 32 is placed in the positioning groove 33, and one side of the pressing ring 31 is hinged to the positioning groove 33. By opening and closing the pressing ring 31, it is convenient to replace the dust-proof cotton 32 and maintain the dust-proof effect of the coarse filtration mechanism 3. When the pressing ring 31 is opened and the dust-proof cotton 32 is removed, the iron powder and dust in the L-shaped tube 4 can be discharged.
[0025] The working principle of the specific embodiment of the present utility model is as follows: When the inhalation valve 14 is opened, the air flow outside the valve body 1 first passes through the coarse filtration mechanism 3. Under the action of the dust-proof cotton 32, large-particle impurity particles are blocked outside the L-shaped tube 4. The initially filtered air flow flows along the L-shaped tube 4 to the electromagnetic assembly 2, and under the action of the magnetic force, the iron powder and iron-containing particles are adsorbed on the magnetization plate 21. The purified air flow passes through the inhalation valve 14 and enters the valve body 1.
