Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically to a homogenizer feeding device. Background Technology

[0002] In industrial applications of high-pressure homogenizers, plunger pumps are a common driving method. The plunger reciprocates with the crankshaft, thus achieving the feeding process. This intermittent feeding and venting causes the liquid flow in the pipeline to exhibit a pulsating state, resulting in significant impact on the pipeline. When the pulse frequency is the same as or close to the natural frequency of the pipeline, resonance may occur, causing strong vibrations in the pipeline. Long-term resonance will exacerbate component fatigue, especially at stress concentration points such as the junction of the valve cavity and the plunger cavity wall within the pump body, which can easily lead to cracks and ultimately material leakage. Utility Model Content

[0003] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a homogenizer feeding device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a homogenizer feeding device, including a main pipeline for guiding materials to the processing area;

[0005] The feed pipe is located on one side of the main pipe to transport materials into the main pipe;

[0006] Buffer mechanism; the buffer mechanism and the feed pipe are respectively arranged opposite to each other on both sides of the main pipe to disperse or absorb the material conveyed by the feed pipe;

[0007] The buffer mechanism includes a housing, which contains a first buffer area and a second buffer area. A first auxiliary pipe is fixedly installed on the outside of the housing, connecting the main pipe of the first buffer area. The axis of the first auxiliary pipe coincides with the axis of the feed pipe. A second auxiliary pipe is fixedly installed on the outside of the housing, connecting the main pipe and the second buffer area. The axis of the second auxiliary pipe does not coincide with the axis of the feed pipe.

[0008] Furthermore, a partition is fixedly installed inside the outer shell, which divides the cavity inside the outer shell into a first chamber and a second chamber. The first buffer zone is located inside the first chamber, the second buffer zone is located inside the second chamber, the first auxiliary pipe is connected to the first chamber, and the second auxiliary pipe is connected to the second chamber.

[0009] Furthermore, the first buffer zone includes a first piston plate slidably disposed in the first chamber, and a first piston rod is fixedly mounted on the first piston plate. The second buffer zone includes a second piston plate slidably disposed in the second chamber. The first piston rod and the second piston rod are jointly fixedly mounted on a connecting plate extending to the outside of the outer casing. A spring is fixedly mounted between the connecting plate and the outer casing. A through hole for connecting the first chamber and the second chamber is opened on the partition plate.

[0010] Furthermore, a limiting plate is fixedly installed on the outer shell, the limiting plate is located on the side of the connecting plate away from the outer shell, the spring is located between the limiting plate and the connecting plate, and the spring is in a compressed state.

[0011] Furthermore, a check valve is installed on the second auxiliary pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: a partition fixedly installed inside the outer shell divides the internal space into a first chamber and a second chamber, making the first chamber and the second chamber independent of each other. A first buffer zone is installed in the first chamber to absorb or buffer pressure or impact from the first auxiliary pipe; a second buffer zone is installed in the second chamber to absorb or buffer the impact of the remaining material flow from the first buffer zone. In this way, the material flow in the feed pipe is buffered in stages, improving the service life of the buffering mechanism. Simultaneously, when the material flow in the first buffer zone flows back, the material in the second buffer zone is less likely to flow back to the first buffer zone, reducing the impact force between the backflowing material flow and the material flow in the feed pipe, greatly improving the buffering effect.

[0015] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figure 1 This embodiment provides a homogenizer feeding device, including a main pipe 1, for guiding materials to the processing area;

[0017] Feed pipe 2 is located on one side of main pipe 1 to transport materials into main pipe 1;

[0018] Buffer mechanism 3; The buffer mechanism 3 and the feed pipe 2 are respectively arranged opposite to each other on both sides of the main pipe 1 to disperse or absorb the material conveyed by the feed pipe 2;

[0019] Main pipe 1 is responsible for guiding the material to the processing area; feed pipe 2 transports the material into main pipe 1; buffer mechanism 3 disperses or absorbs the material flow from feed pipe 2, reduces the impact of liquid flow pulses on main pipe 1, thereby reducing the pressure and impact on main pipe 1 and improving the operational stability and lifespan of the equipment.

[0020] The buffer mechanism 3 includes a housing 31, which contains a first buffer zone 32 and a second buffer zone 33. A first auxiliary pipe 34, which connects to the main pipe 1 of the first buffer zone 32, is fixedly installed outside the housing 31. The axis of the first auxiliary pipe 34 coincides with the axis of the feed pipe 2. A second auxiliary pipe 35, which connects the main pipe 1 and the second buffer zone 33, is fixedly installed outside the housing 31. The axis of the second auxiliary pipe 35 does not coincide with the axis of the feed pipe 2.

[0021] The axis of the first auxiliary pipe 34 coincides with the axis of the feed pipe 2 to facilitate the smooth introduction of materials. The externally installed second auxiliary pipe 35 connects the main pipe 1 and the second buffer zone 33, and the axis of the second auxiliary pipe 35 does not coincide with the axis of the feed pipe 2 to optimize the fluid path. The first buffer zone 32 and the second buffer zone 33 can respectively disperse or absorb the material flow from the feed pipe 2, reduce the impact of liquid flow pulses on the main pipe 1, thereby reducing the pressure and impact on the main pipe 1. By buffering the material flow in the feed pipe 2 twice, the impact of the material flow is greatly reduced.

[0022] A partition 36 is fixedly installed inside the outer shell 31. The partition 36 divides the cavity inside the outer shell 31 into a first chamber 37 and a second chamber 38. The first buffer zone 32 is located in the first chamber 37, and the second buffer zone 33 is located in the second chamber 38. The first auxiliary pipe 34 is connected to the first chamber 37, and the second auxiliary pipe 35 is connected to the second chamber 38.

[0023] A partition 36 fixedly installed inside the outer casing 31 divides its internal space into a first chamber 37 and a second chamber 38, making the first chamber 37 and the second chamber 38 independent of each other. A first buffer zone 32 is installed in the first chamber 37 to absorb or buffer pressure or impact from the first auxiliary pipe 34; a second buffer zone 33 is installed in the second chamber 38 to absorb or buffer the impact of the remaining material flow from the first buffer zone 32. In this way, the material flow in the feed pipe 2 is buffered in stages, improving the service life of the buffer mechanism 3. At the same time, when the material flow in the first buffer zone 32 flows back, the impact force between the backflowing material flow and the material flow in the feed pipe 2 is reduced, because part of the material flow entering the first buffer zone 32 flows into the second buffer zone 33 and enters the main pipe 1 through the second auxiliary pipe 35, reducing the collision with the material flow in the feed pipe 2.

[0024] The first buffer zone 32 includes a first piston plate 321 slidably disposed in the first chamber 37, and a first piston rod 322 is fixedly mounted on the first piston plate 321. The second buffer zone 33 includes a second piston plate 331 slidably disposed in the second chamber 38. The first piston rod 322 and the second piston rod 332 are fixedly mounted on a connecting plate 39 on one side extending to the outside of the outer shell 31. A spring 40 is fixedly mounted between the connecting plate 39 and the outer shell 31. A through hole 41 for connecting the first chamber 37 and the second chamber 38 is opened on the partition plate 36.

[0025] The first buffer zone 32 provides initial buffering of the material flow through a first piston plate 321 slidably disposed within the first chamber 37 and a first piston rod 322 fixedly mounted thereon. The first piston plate 321 slides when impacted by the material flow. The second buffer zone 33 provides further pressure buffering through a second piston plate 331 slidably disposed within the second chamber 38. A connecting plate 39 connects the first piston rod 322 and the second piston rod 332 and is connected to the outer casing 31 by a spring 40. The spring 40 transmits force between the two pistons, enhancing the buffering effect. The through hole 41 on the partition plate 36 serves as a channel for the material flow between the first chamber 37 and the second chamber 38. When the first piston plate 321 of the first buffer zone 32 slides to the through hole 41, some of the material flow in the first chamber 37 flows into the second chamber 38 through the through hole 41, thereby releasing and buffering the high pressure in the first chamber 37. The overall working principle is as follows: the material flow impacts the first piston plate 321, causing it to slide within the first chamber 37 and transfer pressure. When the first piston plate 321 slides to the through hole 41, part of the material flow flows into the second chamber 38 through the through hole 41. Through the further buffering effect of the second piston plate 331, the pressure within the first chamber 37 is effectively reduced, thus achieving dual pressure relief. At the same time, the backflow of the material flow within the first chamber 37 is reduced, minimizing the impact on the material flow within the feed pipe 2.

[0026] A limiting plate 42 is fixedly installed on the outer casing 31. The limiting plate 42 is located on the side of the connecting plate 39 away from the outer casing 31. The spring 40 is located between the limiting plate 42 and the connecting plate 39, and the spring 40 is in a compressed state. When the connecting plate 39 moves, it will continue to compress the spring 40, and elastic potential energy will accumulate in the spring 40 to prepare for the resetting of the connecting plate 39.

[0027] A one-way valve 43 is installed on the second auxiliary pipe 35. This ensures that only the material in the second chamber 38 can flow into the main pipe 1, and that the material in the main pipe 1 is not allowed to flow into the second chamber 38.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
