The right end of the oil inlet pipe is flange-connected to a first three-way joint. The right end of the first three-way joint is flange-connected to a first valve, and the right end of the first valve is flange-connected to an access pipe. During normal operation, only the filter element of the centralized filter needs to be cleaned and replaced, and it is not necessary to clean and replace the filter element of the nozzle filter each time. A bypass pipe and a valve are added at the oil product outlet and inlet of the centralized filter. By opening and closing the valve, the filter element can be cleaned and replaced without stopping business. A magnet is added to adsorb rust, which can effectively adsorb and filter the rust impurities in the filtered oil product, perform grading filtration, reduce the replacement frequency of the internal filter element of the water detection type filter, save the maintenance cost and improve the efficiency.

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] In order to solve the technical problem in the prior art that during the process of disassembling the filter of a fuel dispenser, the residual oil is likely to drip on the hands of the staff or other components, which not only causes pollution and waste of fuel, but also the oil droplets will drip along the components onto the sand grains on the fuel dispenser base, thus forming hazardous waste, the present utility model provides a drip - proof device for the fuel pipe filter when disassembling, which can realize temporarily storing the residual fuel when cleaning or replacing the filter element and releasing the residual fuel after cleaning or replacement, not only avoiding fuel leakage but also saving fuel.

[0026] It should be noted that the anti-drip device for the fuel pipe filter during disassembly of the present utility model is used for, but not limited to, fuel dispensers, etc. For the convenience of description, in the present utility model, only the case where the anti-drip device for the fuel pipe filter during disassembly is applied to a fuel dispenser is taken as an example for description. The principle of applying the anti-drip device for the fuel pipe filter during disassembly to other types of equipment is substantially the same as that applied to the fuel dispenser, and will not be elaborated here one by one.

[0027] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the anti-drip device for the fuel pipe filter during disassembly in an embodiment of the present utility model. The anti-drip device for the fuel pipe filter during disassembly includes an oil barrel assembly 1, a transfer assembly 2, and a filter element 3. The oil barrel assembly 1 includes an oil barrel 11 and an oil cap 12. The oil barrel 11 is provided with a communicating oil storage chamber 111 and an inlet / outlet. The oil cap 12 is detachably connected to the inlet / outlet. The filter element 3 is arranged in the oil storage chamber 111. When the oil cap 12 is disassembled from the inlet / outlet, the inlet / outlet communicates the oil storage chamber 111 with the external air. At this time, the filter element 3 can be removed from the oil storage chamber 111 or the cleaned filter element 3 can be reinserted into the oil storage chamber 111.

[0028] The transfer assembly 2 includes a transfer chamber 21 and a piston 22. The transfer chamber 21 is connected to the oil barrel 11 and internally provided with a transfer cavity 211. The transfer cavity 211 communicates with the oil storage chamber 111, so that the fuel in the oil storage chamber 111 can enter the transfer cavity 211 and the fuel in the transfer cavity 211 can enter the oil storage chamber 111. The piston 22 is slidably arranged in the transfer cavity 211. Specifically, the shape of the piston 22 is adapted to the shape of the transfer cavity 211, for example, both are circular, so that the piston 22 seals and slides with the cavity wall of the transfer cavity 211, which can prevent oil leakage due to the existence of gaps between the piston 22 and the cavity wall of the transfer cavity 211. When the piston 22 slides away from the oil storage chamber 111, it can form a negative pressure in the oil storage chamber 111, sucking the fuel in the oil storage chamber 111 into the transfer cavity 211 for temporary storage. After the filter element 3 is cleaned, the piston 22 is then controlled to slide towards the oil storage chamber 111, pushing the fuel in the transfer cavity 211 into the oil storage chamber 111.

[0029] In one of the embodiments, please refer to Figure 2 , the transfer assembly 2 further includes a pull rod 23. One end of the pull rod 23 extends into the transfer cavity 211 and is connected to the piston 22. The other end of the pull rod 23 extends out of the transfer chamber 21 and is connected to a handle 24. The size of the handle 24 is larger than the diameter of the pull rod 23, so as to facilitate the staff to hold the handle 24 and drive the piston 22 to reciprocate through the pull rod 23, thereby driving the fuel in the oil storage chamber 111 to enter the transfer cavity 211, or pushing the fuel in the transfer cavity 211 into the oil storage chamber 111. In other embodiments, the piston 22 can also be connected to a driving cylinder, and the piston 22 is automatically driven to reciprocate by the driving cylinder. Compared with the manual driving method, the method of using the driving cylinder to drive is time-saving and labor-saving.

[0030] In one embodiment, please refer to Figure 2 , the transfer assembly 2 further includes a first magnetic member 25 and a second magnetic member 26. The first magnetic member 25 is disposed on the side of the piston 22 facing away from the fuel storage chamber 111, and the second magnetic member 26 is disposed in the transfer chamber 21. When the piston 22 slides toward the fuel storage chamber 111 to completely push out the fuel from the transfer chamber 211, the first magnetic member 25 and the second magnetic member 26 are magnetically attracted to each other, so that when the piston 22 completely pushes out the fuel from the transfer chamber 211, the piston 22 can be positioned by the adsorption of the first magnetic member 25 and the second magnetic member 26, which can not only ensure that all the fuel is pushed into the fuel storage chamber 111, but also prevent the piston 22 from moving excessively toward the fuel storage chamber 111 and squeezing the filter element 3. Since both the filter element 3 and the fuel storage chamber 111 are cylindrical and the outer diameter of the filter element 3 is equal to the diameter of the fuel storage chamber 111, when the first magnetic member 25 and the second magnetic member 26 are magnetically attracted to each other, the piston 22 just contacts the filter element 3. The side of the piston 22 facing the fuel storage chamber 111 has an arc surface, and the radian of the arc surface is equal to the radian of the filter element 3, so that the surface of the piston 22 can fully contact the surface of the filter element 3 and prevent the piston 22 from squeezing the filter element 3 and deforming it.

[0031] In one embodiment, please refer to Figure 2 , the transfer assembly 2 further includes a third magnetic member 27. The third magnetic member 27 is disposed at the end of the transfer chamber 21 away from the oil barrel 11. When the piston 22 slides away from the fuel storage chamber 111 and approaches the bottom of the transfer chamber 211, the first magnetic member 25 on the piston 22 is magnetically attracted to the third magnetic member 27 to position the piston 22 and prevent the piston 22 from sliding reciprocally out of control. In other embodiments, the third magnetic member 27 may not be provided, and the staff can always hold the control handle 24 by hand.

[0032] In one embodiment, the outer wall of the transfer chamber 21 is provided with a first installation groove and a second installation groove (not shown in the figure). The second magnetic member 26 is embedded in the first installation groove, and the third magnetic member 27 is embedded in the second installation groove, so that the second magnetic member 26 and the third magnetic member 27 are installed and fixed without occupying extra space.

[0033] In one embodiment, please refer to Figure 1 and Figure 2, the oil barrel assembly 1 further includes a plurality of nuts 13 and screws 14. Each screw 14 passes through the oil cap 12 and is threadedly connected to the oil barrel 11. The plurality of screws 14 and nuts 13 are all arranged around the circumferential side of the oil cap 12. The plurality of nuts 13 are fixedly connected to the corresponding screws 14. The staff can use a wrench to turn the nuts 13 to drive the screws 14 to rotate. The screws 14 are threadedly connected to the oil barrel 11, so that the oil cap 12 and the oil barrel 11 are detachably connected. In other embodiments, the oil cap 12 and the oil barrel 11 can also be connected by other detachable means, such as threaded connection or snap connection, etc. When the oil cap 12 is detached from the oil barrel 11, the staff can take out the filter element 3 in the oil storage cavity 111. After cleaning or replacing the filter element 3, put it back into the oil storage cavity 111, and then reconnect the oil cap 12 to the oil barrel 11.

[0034] In one embodiment, please refer to Figure 2 , the oil barrel 11 is provided with a ventilation hole communicating with the oil storage cavity 111. The oil barrel assembly 1 further includes a sealing cover 15. The sealing cover 15 is detachably connected to the ventilation hole. When the sealing cover 15 is separated from the ventilation hole, the piston 22 can suck the fuel in the oil storage cavity 111 into the transfer cavity 211. Since the size of the ventilation hole is small, when the piston 22 slides away from the oil storage cavity 111, a relatively large negative pressure will still be formed in the oil storage cavity 111, driving the remaining fuel in the oil storage cavity 111 into the transfer cavity 211. The ventilation hole is provided to make the piston 22 slide away from the oil storage cavity 111 more smoothly.

[0035] In one embodiment, please refer to Figure 2 , the sealing cover 15 includes a sealing rod 151 and a driving handle 152 which are integrally formed. The sealing rod 151 is made of rubber material and is connected to the ventilation hole by a sealing plugging method. The area of the driving handle 152 is larger than that of the sealing rod 151, which is convenient for the staff to hold the driving handle 152 to drive the sealing rod 151 to insert into or pull out from the ventilation hole.

[0036] To better understand the present invention, the following will combine Figures 1 to 3 to describe the technical solution of the present invention in detail:

[0037] When it is necessary to clean or replace the filter element 3, the staff first opens the sealing cover 15, holds the handle 24 and drives the piston 22 to slide away from the oil storage cavity 111 to form a negative pressure in the oil storage cavity 111. The fuel in the oil storage cavity 111 flows into the transfer cavity 211 for temporary storage. Use a wrench to clamp the nut 13 and drive the screw 14 to rotate to disassemble the oil cap 12 and take out the filter element 3; after cleaning or replacing the filter element 3, put it into the oil storage cavity 111 and install the oil cap 12; the staff holds the handle 24 and drives the piston 22 to slide towards the oil storage cavity 111 to push the fuel into the oil storage cavity 111, and finally cover the sealing cover 15. The whole operation process can not only avoid fuel leakage and environmental pollution, but also save fuel.

[0038] The specific implementation manners of the present utility model described above do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
