Description

Technical Field

[0001] This utility model relates to the field of bottled gas technology, and in particular to a liquefied petroleum gas cylinder compression and residue removal device. Background Technology

[0002] Currently, some liquefied petroleum gas (LPG) cylinders on the market contain a lot of impurities. As a result, after multiple refills, residual liquid accumulates at the bottom of the cylinders. The main components are butane, pentane, and other non-volatile substances. If this liquid is not drained, the capacity of the cylinders will be reduced during subsequent refills, causing losses to users. Improper disposal will also pose a significant danger.

[0003] In the existing technology, some devices cannot effectively clamp different tanks, making it inconvenient to perform compression and residue removal on different tanks, which has limitations and affects the efficiency of compression and residue removal. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of some devices that cannot effectively clamp different tanks, are inconvenient to perform compression and residue removal on different tanks, have limitations, and affect the efficiency of compression and residue removal. Therefore, a liquefied petroleum gas cylinder compression and residue removal device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquefied petroleum gas cylinder compression and residue removal device includes a main body, a processing tank on the main body, a clamping assembly inside the processing tank, a clamping mechanism on the clamping assembly, a handle rotatably mounted on the main body, a knob rotatably mounted on the handle, and an adjustment mechanism on the knob.

[0007] Preferably, a nitrogen tank and a residual liquid storage tank are fixedly installed on the main body. Valves are fixedly installed on both the nitrogen tank and the residual liquid storage tank. Connecting pipes are fixedly installed on both the nitrogen tank and the residual liquid storage tank. Connectors are fixedly installed on multiple connecting pipes. The nitrogen tank injects nitrogen into the tank body to compress the residue, while the residual liquid storage tank collects the residue. Multiple valves, multiple connecting pipes, and multiple connectors work together with the nitrogen tank and the residual liquid storage tank for processing.

[0008] Preferably, the main body is provided with a groove, which cooperates with the connecting pipe on the residual liquid storage tank. The groove prevents friction between the connecting pipe and the main body, which could lead to leakage of residue.

[0009] Preferably, the clamping assembly is provided with multiple rings, all of which are fixedly installed in the processing groove. Multiple fixing posts are fixedly installed between the multiple rings, and multiple anti-slip pads are fixedly installed on each of the multiple fixing posts. An arc-shaped plate is fixedly installed on the ring located at the bottom of the multiple rings. The multiple rings, together with the multiple fixing posts, multiple protective pads and arc-shaped plates, perform preliminary restriction treatment on the tank, which facilitates the subsequent clamping mechanism to clamp the tank.

[0010] Preferably, a rotating cylinder is fixedly installed on the handle, the rotating cylinder is rotatably installed on the main body, and a threaded rod is rotatably installed inside the rotating cylinder. Rotating the handle drives the rotating cylinder to rotate, and the threaded rod is rotatably connected to the rotating cylinder.

[0011] Preferably, the adjusting mechanism includes a nut, which is threadedly connected to a threaded rod. Multiple connecting handles are fixedly installed on the nut, and the multiple connecting handles are fixedly connected to a knob. An mounting plate is fixedly installed on the nut, and the knob drives the nut to rotate through the multiple connecting handles.

[0012] Preferably, the mounting plate is provided with a circular groove, which is slidably connected to the threaded rod. Multiple push rods are fixedly mounted on the mounting plate, and a fixed guide plate is slidably connected to the multiple push rods. The fixed guide plate is fixedly mounted on the clamping assembly. The rotating cylinder is fixedly connected to the fixed guide plate. The rotating cylinder is provided with multiple sliding grooves, which are all slidably connected to the mounting plate. The fixed guide plate restricts the multiple push rods to prevent them from deviating. The multiple sliding grooves on the rotating cylinder facilitate the movement of the push rods by the mounting plate.

[0013] Preferably, the clamping mechanism includes a first clamping plate, which is fixedly connected to the upper push rod among a plurality of push rods. A second clamping plate is fixedly installed on the lower push rod among a plurality of push rods. The plurality of push rods are slidably connected to the left-side fixed column among a plurality of fixed columns. The plurality of push rods push out the first clamping plate and the second clamping plate to clamp the tank.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) Multiple rings and multiple anti-slip pads are used to restrict different tanks, which makes it easier for the first clamping plate and the second clamping plate to clamp the tanks.

[0016] (2) By rotating the knob, the nut, mounting plate and multiple push rods are moved to push the first clamping plate and the second clamping plate to clamp the tank. At the same time, rotating the handle can rotate the clamped tank for processing.

[0017] This utility model has a simple structure. Multiple rings, anti-slip pads, and arc plates initially restrict the tank. Rotating the knob drives the nut to operate, and multiple push rods drive the first clamping plate and the second clamping plate to clamp and fix the tank to prevent slippage. Rotating the handle can make the clamped tank rotate, which facilitates compression and residue removal. Attached Figure Description

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-3 A liquefied petroleum gas cylinder compression and residue removal device includes a main body 1, a processing tank 8 on the main body 1, a clamping assembly 9 inside the processing tank 8, a clamping mechanism on the clamping assembly 9, a handle 10 rotatably mounted on the main body 1, a knob 11 rotatably mounted on the handle 10, and an adjustment mechanism on the knob 11.

[0025] In this embodiment, a nitrogen tank 2 and a residual liquid storage tank 3 are fixedly installed on the main body 1. Valves 4 are fixedly installed on both the nitrogen tank 2 and the residual liquid storage tank 3. Connecting pipes 5 are fixedly installed on both the nitrogen tank 2 and the residual liquid storage tank 3. Connectors 6 are fixedly installed on multiple connecting pipes 5. The nitrogen tank 2 injects nitrogen into the tank body to compress the residue, while the residual liquid storage tank 3 collects the residue. Multiple valves 4, multiple connecting pipes 5, and multiple connectors 6 work together with the nitrogen tank 2 and the residual liquid storage tank 3 to process the residue.

[0026] In this embodiment, the main body 1 is provided with a pipe groove 7, which cooperates with the connecting pipe 5 on the residual liquid storage tank 3. The pipe groove 7 prevents friction between the connecting pipe 5 and the main body 1, which would lead to leakage of residue.

[0027] In this embodiment, the clamping assembly 9 is provided with multiple rings 19, all of which are fixedly installed in the processing groove 8. Multiple fixing posts are fixedly installed between the multiple rings 19, and multiple anti-slip pads 20 are fixedly installed on each of the multiple fixing posts. An arc-shaped plate 21 is fixedly installed on the ring 19 located at the bottom of the multiple rings 19. The multiple rings 19, together with the multiple fixing posts, multiple protective pads 20 and arc-shaped plate 21, perform preliminary restriction treatment on the tank, which facilitates the subsequent clamping mechanism to clamp the tank.

[0028] In this embodiment, a rotating cylinder 12 is fixedly installed on the handle 10. The rotating cylinder 12 is rotatably installed on the main body 1. A threaded rod 14 is rotatably installed inside the rotating cylinder 12. Rotating the handle 10 drives the rotating cylinder 12 to rotate. The threaded rod 14 is rotatably connected to the rotating cylinder 12.

[0029] In this embodiment, the adjustment mechanism includes a nut 13, which is threadedly connected to a threaded rod 14. Multiple connecting handles 24 are fixedly installed on the nut 13, and the multiple connecting handles 24 are fixedly connected to a knob 11. An mounting plate 15 is fixedly installed on the nut 13, and the knob 11 drives the nut 13 to rotate through the multiple connecting handles 24.

[0030] In this embodiment, the mounting plate 15 is provided with a circular groove 16, which is slidably connected to the threaded rod 14. Multiple push rods 17 are fixedly mounted on the mounting plate 15, and a fixed guide plate 23 is slidably connected to the multiple push rods 17. The fixed guide plate 23 is fixedly mounted on the clamping assembly 9. The rotating cylinder 12 is fixedly connected to the fixed guide plate 23. The rotating cylinder 12 is provided with multiple sliding grooves, which are all slidably connected to the mounting plate 15. The fixed guide plate 23 restricts the multiple push rods 17 to prevent them from shifting. The multiple sliding grooves on the rotating cylinder 12 facilitate the movement of the push rods 17 by the mounting plate 15.

[0031] In this embodiment, the clamping mechanism includes a first clamping plate 18, which is fixedly connected to the upper push rod 17 among a plurality of push rods 17. A second clamping plate 22 is fixedly installed on the lower push rod 17 among a plurality of push rods 17. The plurality of push rods 17 are slidably connected to the left-side fixed column among a plurality of fixed columns. The plurality of push rods 17 push out the first clamping plate 18 and the second clamping plate 22 to clamp the tank.

[0032] In this embodiment, the tank is placed upside down inside the clamping assembly 9. By rotating the knob 11, the nut 13 is rotated, causing multiple push rods 17 on the mounting plate 15 to move. The multiple push rods 17 push the first clamping plate 18 and the second clamping plate 22 to move respectively, clamping and fixing the tank. The connector 6 on the nitrogen tank 2 is connected to the tank. The valve 4 on the nitrogen tank 2 is opened, and nitrogen gas is injected into the tank through the connecting pipe 5 on the nitrogen tank 2 to increase the internal pressure. When the internal pressure of the tank reaches 1.5MPa, the valve 4 is closed, the connector 6 on the nitrogen tank 2 is removed, and the connector 6 of the residual liquid storage tank 3 is connected to the tank. By rotating the handle 10, the clamped tank is rotated, causing the tank to be upside down. The valve 4 of the residual liquid storage tank 3 is opened. Due to the nitrogen, the residue inside the tank is squeezed out. Combined with the gravity inside the upside-down tank, the residue is collected, completing the processing of the residual leaves.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that a hammer is fixedly installed on the main body 1, which, together with the reciprocating mechanism, automatically strikes the bottom of the tank to remove residues from the inner wall of the tank, thereby increasing the residue removal effect. All structures in this application can be selected in terms of material and length according to actual use. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted appropriately.

[0035] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
