Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a pulsation attenuator with replaceable internal components. Background Technology

[0002] During the operation of the compressor unit, airflow pulsation in the intake and exhaust pipes is a common problem that needs to be solved. In order to eliminate this airflow pulsation, buffers are usually configured between stages and at the inlet. For buffers without internal structural components, their effect in eliminating airflow pulsation is often poor. Therefore, it is necessary to use buffers with internal structural components, i.e. pulsation dampers.

[0003] However, existing traditional pulsation attenuators have obvious drawbacks. Their structure involves welding the internal components directly into the container. When the compressor's operating conditions change and the internal components need to be replaced, the entire container equipment must be replaced because the internal components are welded to the container. In reality, the majority of the cost of a pulsation suppression device comes from the equipment itself, not the internal components. Therefore, replacing the entire device would result in a huge waste of resources, increase manpower and material costs, extend the maintenance cycle, and affect production efficiency and economic benefits. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pulsation attenuator with replaceable internal components, which solves the problem that existing pulsation attenuators have an internally welded structure, making them inconvenient to inspect and replace.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pulsation attenuator with replaceable internal components, comprising a detachably connected front end housing and a rear end housing, wherein a spherical crown-shaped partition is clamped between the front end housing and the rear end housing, and a horizontally arranged filter tube is provided through the center of the spherical crown-shaped partition.

[0006] Preferably, the front end housing and the rear end housing are each provided with a flange that can be bolted to each other at their respective ends, and the outer circle of the spherical partition is embedded between a pair of flanges.

[0007] Preferably, a gasket is provided at the connection between the flange and the spherical partition.

[0008] Preferably, the spherical partition and the filter tube are connected by welding.

[0009] Beneficial effects

[0010] This utility model provides a pulsation attenuator with replaceable internal components, which has the following advantages:

[0011] The replaceable internal pulsation attenuator adopts a detachable structure. The internal components and the shell are non-welded and are clamped together by the equipment flange. When the compressor needs to change its operating conditions and the internal components need to be replaced, only the container needs to be opened to disassemble and replace the internal components. It is not necessary to replace the entire equipment, which greatly saves the high cost incurred by replacing the entire equipment. By saving costs and shortening the maintenance cycle, the operation of the chemical plant becomes more efficient and economical. While ensuring the normal operation of the equipment, it reduces production costs, improves the economic benefits of the production cycle, and enhances the company's competitiveness in the market.

[0014] 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.

[0015] Please see Figure 1 This utility model provides a technical solution: a pulsation attenuator with replaceable internal components, including a front end housing 5 and a rear end housing 1 that are detachably connected. A spherical crown-shaped partition 3 is clamped between the front end housing 5 and the rear end housing 1. A horizontally arranged filter tube 4 is provided through the center of the spherical crown-shaped partition 3.

[0016] By adopting the above technical solution, the front housing 5 and the rear housing 1 are detachably connected, providing operating space for the replacement of internal components. The spherical baffle 3 is clamped between the front and rear housings, and the filter tube 4 is horizontally arranged through the center of the spherical baffle 3. The spherical baffle 3 and the filter tube 4 together constitute the internal components, which are used to eliminate airflow pulsation. Through this detachable structural design, when it is necessary to replace the internal components, the front and rear housings can be easily opened for operation, realizing the separation of the internal components from the housings, creating conditions for the replacement of internal components, and solving the problem that the internal components of traditional pulsation attenuators cannot be replaced.

[0017] In this embodiment, the front end housing 5 and the rear end housing 1 are each provided with a flange that can be connected by bolts at their respective ends, and the outer circle of the spherical partition 3 is embedded between a pair of flanges.

[0018] By adopting the above technical solution, the front and rear shells can be firmly connected together by bolted flanges. The outer circle of the spherical crown-shaped partition 3 is embedded between a pair of flanges. The clamping force of the flanges is used to fix the spherical crown-shaped partition 3 in a suitable position, while also ensuring the sealing of the entire device.

[0019] In this embodiment, a gasket 2 is provided at the connection between the flange and the spherical partition 3.

[0020] By adopting the above technical solution, the gasket 2 can fill the tiny gaps at the connection, enhance the sealing performance, and prevent air leakage. At the same time, the gasket 2 can also play a role in buffering and shock absorption, reducing the impact of vibration and pressure changes on the connection.

[0021] In this embodiment, the spherical partition 3 and the filter tube 4 are connected by welding.

[0022] By adopting the above technical solution, welding can make the two form a solid whole, ensuring that the position of the filter tube 4 on the spherical baffle 3 is fixed, and ensuring that the airflow can pass through the filter tube 4 and the spherical baffle 3 as designed, so as to effectively eliminate airflow pulsation.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example: During assembly, the filter tube 4 is positioned by passing through the spherical crown-shaped partition 3. After positioning, the filter tube 4 and the spherical crown-shaped partition 3 are welded together to form a complete internal component. According to the operating conditions, a gasket 2 of appropriate material is selected and placed at the connection between the flange of the front housing 5 and the rear housing 1, which are close to each other, and the spherical crown-shaped partition 3. Then, the front and rear housings are used to clamp the spherical crown-shaped partition 3 together. Finally, bolts are passed through the holes on the flanges and tightened to firmly connect the front and rear housings and the spherical crown-shaped partition 3 together, thus completing the assembly of the entire pulsation attenuator.

[0025] When the compressor's operating conditions change and internal parts need to be replaced, first loosen the bolts connecting the front and rear housing flanges, open the container. Since the internal parts are not welded to the housing, they can be directly removed from the container, making them convenient to use.

[0026] Specifically, this embodiment only uses a two-section shell structure for illustration. In actual use, the container can be a multi-section structure such as a two-section shell or a three-section shell. The internal components can be various combinations of filter tube 4 with baffles and accessories, thereby adapting to different operating conditions and user needs, and improving the applicability and versatility of the product.
