Description

Technical Field

[0001] This utility model relates to the field of liquid filling pump technology, specifically to a liquid filling pump anti-clogging device. Background Technology

[0002] A liquid pump is a type of pump used to transport liquids. It draws liquid from one container or pipe and delivers it to another container or pipe by means of mechanical or electric means. This type of pump is usually used to achieve precise flow control and can be used in various applications such as chemical, pharmaceutical, and food processing. It has high precision and reliability and can ensure the accuracy and stability of liquid delivery.

[0003] Liquid filler pumps are also commonly used for transporting petroleum. However, petroleum is a liquid with poor fluidity in cold weather or cold environments, which can cause it to clump together. This can easily cause blockages when using a liquid filler pump. In addition, petroleum itself contains some solid impurities. If these impurities are not filtered, they will accumulate inside the liquid filler pump during the transport process, affecting the normal transport of petroleum. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] Example 1

[0027] A liquid filling pump anti-clogging device includes a housing 1, a top cover 2 threadedly connected to the top of the housing 1, a filter cylinder 3 disposed inside the housing 1, an electric heating ring tube 4 fixedly disposed on the inner wall of the housing 1, the electric heating ring tube 4 being concentrically disposed with the filter cylinder 3, an agitation mechanism disposed inside the filter cylinder 3, an inlet 20 disposed on the side of the housing 1, a conical part 21 disposed at the bottom of the housing 1, and an outlet 22 disposed at the bottom end of the conical part 21.

[0028] The agitation mechanism includes a motor 5, a main shaft 6, a sleeve 7, a crossbar 8, and an agitator 9. The motor 5 is fixedly mounted on the surface of the top cover 2. The main shaft 6 is rotatably mounted at the center of the top cover 2, and the top of the top cover 2 is keyed to the output end of the motor 5. The sleeve 7 is fixedly mounted at the center of the filter cylinder 3. The bottom end of the main shaft 6 extends into the interior of the sleeve 7. The crossbar 8 is vertically fixed to the surface of the main shaft 6, and the agitator 9 is vertically fixed to the surface of the crossbar 8.

[0029] Please see Figure 2 and 4The motor 5 can drive the main shaft 6 to rotate. The bottom end of the main shaft 6 can rotate inside the sleeve 7. When the main shaft 6 rotates, it can drive the stirring rod 9 to revolve through the crossbar 8, thereby stirring the clumped oil. With the action of the stirring rod 9 and the setting of the electric heating ring tube 4, the clumped oil can slowly return to a flowing state, thereby flowing through the mesh on the surface of the filter cylinder 3 to the conical part 21, and finally being discharged through the outlet 22.

[0030] A liquid collection tray 16 is fixedly installed on the top of the filter cartridge 3. The liquid collection tray 16 is a conical structure, and the outer diameter of the liquid collection tray 16 is larger than the outer diameter of the filter cartridge 3 and the same as the inner diameter of the housing 1. A base 17 matching the liquid collection tray 16 is fixedly installed on the inner wall of the housing 1. The liquid collection tray 16 is placed on the surface of the base 17 by a positioning member. The positioning member includes a positioning block 18 fixedly installed at the bottom of the liquid collection tray 16 and a positioning groove 19 provided on the surface of the base 17. The positioning block 18 is engaged inside the positioning groove 19.

[0031] Please see Figure 2 , 3 When the top cover 2 is opened, the main shaft 6 can be separated from the sleeve 7 when the top cover 2 is removed. At this time, the liquid collection tray 16 can be directly removed from the inside of the housing 1 to facilitate cleaning of the filter cartridge 3 and the inner wall of the housing 1. When installing the filter cartridge 3, the positioning block 18 and the positioning groove 19 are used to align the liquid collection tray 16 with the base 17. At this time, the positioning block 18 and the positioning groove 19 can limit the liquid collection tray 16 and the filter cartridge 3 in the circumferential direction.

[0032] Example 2

[0033] In the above embodiment, the agitation mechanism agitates the clumped oil in the filter cylinder 3. However, the movement mode of the agitator 9 is relatively simple, making it difficult to completely break up the clumped oil. Therefore, in this embodiment, an auxiliary mechanism is provided on the crossbar 8. The auxiliary mechanism includes a drive rod 10, a spring 11, a blade 12, and a traction seat 13. The drive rod 10 is vertically and movably disposed inside the agitator 9. The spring 11 is fixed between the agitator 9 and the drive rod 10 by a limiting member. The blade 12 is fixedly disposed at the bottom end of the drive rod 10. The traction seat 13 is fixedly disposed on the surface of the top cover 2. A connecting rod 23 is fixedly disposed on the surface of the drive rod 10. An arc-shaped baffle 24 is fixedly disposed at one end of the two connecting rods 23. The arc-shaped baffle 24 is attached to the inner wall of the housing 1. The bottom of the traction seat 13 is set as a triangular structure, and the bottom of the traction seat 13 is set as a rounded corner.

[0034] The limiting component includes a first retaining ring 14 and a second retaining ring 15. The first retaining ring 14 is fixedly disposed on the inner wall of the stirring rod 9, and the inner wall of the first retaining ring 14 is attached to the surface of the driving rod 10. The second retaining ring 15 is fixedly disposed on the surface of the driving rod 10, and the outer wall of the second retaining ring 15 is attached to the inner wall of the stirring rod 9. The spring 11 is fixedly disposed between the second retaining ring 15 and the lower first retaining ring 14.

[0035] Please see Figure 5 and 7 The main shaft 6 drives the agitator 9 to revolve via the crossbar 8. During this revolve, the agitator 9 drives the drive rod 10 to rotate synchronously. The drive rod 10 then drives the blades 12 to rotate synchronously, causing the blades 12 to revolve inside the filter cartridge 3. This continuous rotation of the blades 12 breaks up any clumps of oil. Since the traction seat 13 is fixed, while the top of the drive rod 10 revolves continuously, when the drive rod 10 just comes into contact with the traction seat 13, the bottom slope of the traction seat 13 presses against the drive rod 10. As the drive rod 10 continues to rotate, the bottom slope of the traction seat 13 continuously drives the drive rod 10 downwards, causing the drive rod 10 to drive the blades 12 downwards. When the drive rod 10 contacts the lowest point of the traction seat 13, the drive rod 10 and the blades 12 are just... As the drive rod 10 moves down to the lowest point, during the process described above, it drives the second retaining ring 15 to move synchronously. Since the position of the first retaining ring 14 is fixed, the distance between the second retaining ring 15 and the first retaining ring 14 gradually decreases, thereby continuously compressing the spring 11 to store energy. When the drive rod 10 continues to rotate, the drive rod 10 separates from the lowest point of the traction seat 13, and the spring 11 releases energy, thereby driving the drive rod 10 to reset, which in turn causes the drive rod 10 to drive the blade 12 to reset. Since the blade 12 moves down first and then resets, and the blade 12 continues to revolve continuously during this process, the blade 12 can break up the clumps of oil from different directions, thereby preventing blockages when the oil is subsequently transported by the liquid filling pump.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
