Description

Technical Field

[0001] This utility model relates to the field of supply device technology, and in particular to a supply device for conveying high-viscosity fluid. Background Technology

[0002] The combination of liquefied natural gas (LNG) carriers and supply units for high-viscosity fluids has brought convenience to the energy transportation sector, with the supply units playing a crucial role in this system. These units are typically used for transporting high-viscosity fluids such as oil and asphalt, but in LNG transportation, they are modified to adapt to cryogenic environments. These units are equipped with efficient heating systems to ensure the smooth flow of LNG even at low temperatures.

[0003] Therefore, selecting appropriate transmission equipment and methods is crucial for ensuring the smooth transmission of high-viscosity fluids. According to the authorized publication number "CN217327702U", a high-viscosity fluid conveying device with filtration and mixing function is disclosed. This solves the problem in existing technologies where high-viscosity fluids containing many impurities are likely to adhere to the inner wall of the conveying device during flow, causing blockages over time and severely affecting the efficiency of the conveying device, thus requiring time-consuming and labor-intensive cleaning. The high-viscosity fluid conveying device with filtration and mixing function includes a housing, with both ends of the housing fixedly connected to transmission pipes via conversion pipes. A connecting piece is installed at the end of the transmission pipe away from the conversion pipe. Support plates are symmetrically fixedly connected to the outer ring of the housing, and a drive motor is installed on the top of one of the support plates. This invention avoids pipe blockage caused by impurities in high-viscosity fluids, improves the efficiency of the device, and reduces enterprise operating costs.

[0004] Currently, centrifugal pumps and diaphragm pumps are the main types of pumps used for fluid transfer. However, when transferring high-viscosity fluids, both types of pumps may cause unstable flow rates due to the high viscosity of the fluid, affecting the continuity and stability of the production process. Centrifugal pumps and diaphragm pumps may also cause insufficient pressure when transferring high-viscosity fluids, failing to meet the needs of the production process. Therefore, it is necessary to design a structure specifically for the transfer of high-viscosity fluids to ensure the continuous operation of the production process. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a supply device for transmitting high-viscosity fluids.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a supply device for conveying high-viscosity fluid, comprising a base, with legs fixedly installed on the top of the base, the legs being symmetrically distributed along both sides of the base, and the same conveying channel being installed at the upper end of each of the two legs, the conveying channel being a cylindrical structure, and a sealing plate being welded and fixed at one end of the conveying channel;

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. This solution uses a motor-driven shaft to rotate the spiral blades within the conveying channel, effectively promoting the stable transport of high-viscosity fluids. The design of the spiral blades closely adhering to the inner wall of the conveying channel prevents material stagnation and ensures continuous and uniform conveying.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 A supply device for conveying high-viscosity fluid includes a base 1, with legs 11 fixedly installed on the top of the base 1. The legs 11 are symmetrically distributed along both sides of the base 1. The upper ends of the two legs 11 are each equipped with the same conveying channel 12. The conveying channel 12 has a cylindrical structure. A sealing plate 13 is welded and fixed to one end of the conveying channel 12. The conveying channel 12 can convey high-viscosity fluid, and the sealing plate 13 can seal one end of the conveying channel 12.

[0028] The bearing 14 is fixedly inserted inside the sealing plate 13. The shaft 15 is inserted inside the bearing 14. One end of the shaft 15 extends into the interior of the conveying channel 12. The surface of the shaft 15 is interference-fitted with the inner ring wall of the bearing 14. The shaft 15 rotates based on the bearing 14, which can ensure the stable rotation of the spiral blade 17.

[0029] A motor 16 is installed at the end of the shaft 15 away from the conveying channel 12. The outer ring wall of the motor 16 is fixed to the surface of the support leg 11 by a bracket. The motor 16 has a drive shaft inside, and the end of the drive shaft is fixedly connected to the shaft 15 by a coupling. A spiral blade 17 is fixedly wound on the surface of the shaft 15. The outer spiral surface of the spiral blade 17 is rotated and tightly attached to the inner wall of the conveying channel 12. When the power of the motor 16 is turned on, its shaft can drive the shaft 15 to rotate, thereby realizing the rotation of the spiral blade 17. Thus, high-viscosity fluid can be stably conveyed.

[0030] The conveying channel 12 is covered with a heat-conducting sleeve 2. The heat-conducting sleeve 2 has a half-splitting structure, consisting of a left half and a right half. The heat-conducting sleeve 2 is made of aluminum alloy and has good thermal conductivity. The conveying channel 12 is made of corrosion-resistant stainless steel. The heat-conducting sleeve 2 can stably transfer heat to the conveying channel 12, which can heat fluids with high viscosity and further reduce their adhesion during conveying.

[0031] The heat-conducting sleeve 2 has several heating tubes 21 fixed inside. The heating tubes 21 are symmetrically distributed along the left and right halves of the sleeve. The heating tubes 21 can be integrated into a circuit and the temperature can be controlled by a unified temperature control switch, thereby achieving stable heating of the heat-conducting sleeve 2.

[0032] The left half of the set is fixed with connecting plate 1 22 at the top and bottom ends respectively, and the right half of the set is fixed with connecting plate 25 at the top and bottom ends respectively. The specifications of connecting plate 1 22 and connecting plate 25 are the same and their positions correspond. When the heat-conducting sleeve 2 is spliced ​​in half on the conveying channel 12, connecting plate 1 22 and connecting plate 25 can play a transitional connection installation effect.

[0033] In this design, fastening bolts 23 are installed through the interior of both the first connecting plate 22 and the second connecting plate 25. A nut 24 is threaded onto the other end of the fastening bolt 23. The end of the fastening bolt 23 is in contact with the surface of the second connecting plate 25, and the end face of the nut 24 is in contact with the surface of the first connecting plate 22. Holes for the fastening bolts 23 to pass through are provided on the surfaces of both the first connecting plate 22 and the second connecting plate 25. By having the fastening bolts 23 pass through the holes at the same position and are assembled with the nut 24, the half-splitting of the heat-conducting sleeve 2 can be stably spliced.

[0034] The conveying channel 12 is provided with a feed inlet 3 through one side near the sealing plate 13. A feed funnel 31 is fixed to the end of the feed inlet 3. A feed ramp 32 is provided through one side of the feed funnel 31. The feed ramp 32 has a U-shaped structure. The feed inlet 3 can feed high-viscosity fluid during the conveying process. The feed funnel 31 and the feed ramp 32 can extend the feed inlet 3 and can feed fluid from one side.

[0035] Among them, a second motor 33 is installed above the feed hopper 31. The outer wall of the second motor 33 is fixedly installed on the surface of the conveying channel 12 through a bracket. The second motor 33 has a rotating shaft 2 for driving inside. By connecting the power supply of the second motor 33, the rotating shaft 2 can be rotated. At the same time, the shaft 2 34 can be rotated synchronously.

[0036] The two ends of the rotating shaft are fixedly connected to the shaft 34 via a coupling. The surface of the shaft 34 is fixedly wound with a spiral blade 35. The outer spiral surface of the spiral blade 35 is fitted against the inner wall of the feed port 3. During vertical feeding, in order to avoid the high viscosity fluid from sticking to the inner wall of the feed port 3, the rotation of the shaft 34 can cause the spiral blade 35 to rotate, forming a spiral feeding position at the feeding position, thereby ensuring the continuous stability of the overall feeding process.

[0037] In practice

[0038] This solution uses a motor 16 to drive the shaft 15 to rotate, and the spiral blade 17 fixedly wound on the surface of the shaft 15 rotates accordingly. The outer spiral surface of the spiral blade 17 is tightly fitted with the inner wall of the conveying channel 12 to form a continuous spiral propulsion space. When the high-viscosity fluid enters the conveying channel 12 from the feed port 3, the rotating spiral blade 17 will generate an axial thrust on the fluid, forcing the fluid to move along the conveying channel 12 towards the outlet. Due to the tight fit between the spiral blade 17 and the inner wall of the channel, it can effectively prevent fluid backflow or local stagnation. The bearing 14 supports the shaft 15 to ensure its rotational stability, while the sealing plate 13 seals one end of the conveying channel 12 to maintain the seal.

[0039] The heat-conducting sleeve 2 is wrapped around the outer wall of the conveying channel 12. It is made of aluminum alloy and is divided into a left half and a right half. It is fixed by connecting plate 1 22, connecting plate 25, fastening bolts 23 and nuts 24. Multiple electric heating tubes 21 are embedded inside the heat-conducting sleeve 2 and are symmetrically distributed in the left and right half. When the electric heating tubes 21 are energized, they generate heat and are quickly conducted to the conveying channel 12 through the aluminum alloy material to indirectly heat the high-viscosity fluid. After the fluid is heated, the viscosity decreases, reducing the adhesion to the inner wall of the channel and the spiral blade 17.

[0040] When the viscous fluid enters the feed inlet 3 through the feed funnel 31 and feed ramp 32, the motor 2 33 drives the rotating shaft 2 to rotate the shaft 2 34. The spiral blade 2 35 on the surface of the shaft 2 34 rotates synchronously. The spiral blade 2 35 fits against the inner wall of the feed inlet 3, forming a forced pushing effect, squeezing the viscous fluid downward into the main cavity of the conveying channel 12.

[0041] The heat-conducting sleeve 2 adopts a half-splitting structure. The left and right halves are aligned with the connecting plate 25 via the connecting plate 1 22. The fastening bolts 23 pass through the holes and are locked with nuts 24. This modular design facilitates disassembly, maintenance, or replacement of the heating element 21. During installation, after the two halves cover the conveying channel 12, the fastening bolts 23 apply radial pressure to ensure that the heat-conducting sleeve 2 is in close contact with the outer wall of the channel.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
