Description

Technical Field

[0001] This utility model relates to the field of refrigeration oil filter technology, and in particular to a vibration-damping refrigeration oil filter. Background Technology

[0002] Refrigeration systems play a vital role in modern society, widely used in food storage and transportation, air conditioning systems, industrial production, and other fields. Refrigeration oil, as an indispensable component of refrigeration systems, primarily functions to lubricate compressors, sealing systems, cooling system components, and remove impurities from the system. The quality and performance of refrigeration oil directly affect the operating efficiency, service life, and energy consumption of the refrigeration system.

[0003] With the continuous development of refrigeration technology, the quality requirements for refrigeration oils are also increasing. Traditional refrigeration oils often contain a certain amount of impurities, such as metal particles, oxides, and moisture. These impurities can have a series of negative impacts on the refrigeration system: Wear on parts: Impurities can accelerate the wear of critical components such as compressors, reduce system efficiency, and shorten service life. Blockage of pipes: Fine impurity particles may accumulate and block pipes, affecting the flow of refrigerant and reducing the cooling effect. Corrosion of the system: Moisture and oxides can corrode metal components in the refrigeration system, leading to leaks and performance degradation.

[0004] To address these issues, efficient filtration of impurities in refrigeration oil has become crucial for ensuring the stable operation of refrigeration systems. Refrigeration oil filters were developed to meet this need and continue to evolve with technological advancements.

[0005] Existing refrigeration oil filters mainly achieve their filtration function through the following methods:

[0006] Mesh filters: These filters use metal mesh to intercept particulate impurities in refrigeration oil. They have a simple structure and low cost, but their filtration accuracy is limited and they are difficult to remove fine impurities.

[0007] Sintered filters: Made of sintered metal powder, they have high filtration accuracy and dirt holding capacity, but are more expensive and more difficult to clean.

[0008] Composite filters combine various filter materials and structures, such as multi-layer metal mesh and pleated filter cartridges, which can balance filtration efficiency and service life, but the structure is more complex and the cost is higher.

[0009] However, traditional refrigeration oil filters still have some shortcomings in practical applications:

[0010] Insufficient vibration and noise reduction performance: Some refrigeration systems, especially large screw or centrifugal refrigeration units, generate significant vibration and noise during operation. Traditional refrigeration oil filters typically lack effective vibration and noise reduction functions and cannot meet increasingly stringent environmental protection requirements.

[0011] Inconvenient installation and maintenance: Some filters have complex structures, and the installation and disassembly process is cumbersome, which is not conducive to maintenance and increases the cost of use. Utility Model Content

[0012] In view of the shortcomings of the existing technology, this utility model aims to provide a new type of vibration-damping refrigeration oil filter, which not only has high-efficiency filtration performance and can effectively remove various impurities in refrigeration oil, but also integrates vibration reduction and noise reduction functions, which can effectively reduce vibration and noise during the operation of the refrigeration system, improve the stability and reliability of equipment operation, and extend its service life.

[0013] To achieve the above objectives, this utility model discloses a vibration-damping type refrigeration oil filter, comprising: a cylindrical outer shell with a refrigeration oil inlet on its side wall and a refrigeration oil outlet at one end; a filter sleeve disposed inside the cylindrical outer shell, with one end closed and the other end open and facing the refrigeration oil outlet; and a shock-absorbing sleeve fitted over the filter sleeve, with one end closed and the other end open and facing the refrigeration oil outlet, so that the refrigeration oil entering the cylindrical outer shell flows sequentially through the shock-absorbing sleeve and the filter sleeve before flowing out from the refrigeration oil outlet. By fitting the shock-absorbing sleeve over the filter sleeve, the refrigeration oil passes through the shock-absorbing sleeve before filtration, which can effectively reduce vibration and noise while ensuring the filtration effect of the refrigeration oil.

[0014] Preferably, the end cap includes at least one annular component for securing and sealing the filter sleeve and the shock-absorbing sleeve. This provides a more reliable secure seal for the filter sleeve and the shock-absorbing sleeve, prevents refrigerant oil leakage, ensures the normal operating pressure of the filter, and improves the reliability and service life of the filter.

[0015] Preferably, the filter sleeve is equipped with multiple layers of composite filter material. By combining different filter materials, impurities and contaminants of different sizes can be intercepted more effectively, improving filtration accuracy and efficiency, ensuring the purity of the refrigeration oil, and extending the service life of the equipment.

[0016] Preferably, the material of the damping sleeve is selected from one or more of rubber, spring steel, and damping alloy, and the damping sleeve is provided with several through holes. By using damping material, vibration energy can be better absorbed, vibration amplitude can be reduced, the impact of vibration on equipment and the surrounding environment can be reduced, and the stability and reliability of equipment operation can be improved. The presence of through holes alters the oil flow path; when the refrigeration oil flows through the damping sleeve, its flow path is changed, no longer a simple straight line. This path change can effectively buffer oil pressure fluctuations and reduce vibration transmission. When the oil flows through the through holes, it will rub against the hole wall, converting some vibration energy into heat energy for dissipation, thereby reducing vibration transmission. The presence of through holes increases the contact area between the damping material and the refrigeration oil, allowing for more effective absorption of vibration energy.

[0017] Preferably, the cylindrical outer shell is made of stainless steel or aluminum alloy. This improves the shell's strength and corrosion resistance, enabling it to withstand higher pressures and harsher working environments, thus extending the filter's service life.

[0018] In summary, this novel vibration-damping refrigeration oil filter, through its structural design of placing the vibration-damping sleeve outside the filter sleeve, and the selection and optimization of materials for each component, effectively solves the problems of insufficient vibration and noise reduction performance, inconvenient installation and maintenance, and limited functionality in existing technologies, providing a refrigeration oil filtration solution that is simple in structure, reliable in performance, and easy to maintain.

[0023] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the structure of a vibration-damping type refrigeration oil filter according to one embodiment of the present invention. Figure 2 This is a cross-sectional schematic diagram of a vibration-damping type refrigeration oil filter according to one embodiment of the present invention. Figure 3This is a top-view structural diagram of a vibration-damping refrigeration oil filter according to one embodiment of this utility model.

[0025] like Figure 1 As shown in Figure 3, this utility model provides a vibration-damping type refrigeration oil filter 10, which includes a cylindrical shell 1 with a refrigeration oil inlet 5 on its side wall and a refrigeration oil outlet 4 at one end; a filter sleeve 3, which is disposed inside the cylindrical shell 1, with one end closed and the other end open and facing the refrigeration oil outlet 4; and a shock-absorbing sleeve 2, which is sleeved outside the filter sleeve 3, with one end closed and the other end open and facing the refrigeration oil outlet 4, so that the refrigeration oil entering the cylindrical shell 1 flows through the shock-absorbing sleeve 2 and the filter sleeve 3 in sequence and then flows out from the refrigeration oil outlet 4.

[0026] Specifically, the cylindrical outer shell 1 is a hollow cylindrical structure, and its material can be selected from stainless steel or aluminum alloy to ensure its strength and corrosion resistance. The side wall of the cylindrical outer shell 1 is provided with a refrigeration oil inlet 5 for refrigeration oil to enter the filter. One end of the cylindrical outer shell 1 is provided with a refrigeration oil outlet 4 for the filtered refrigeration oil to flow out.

[0027] The filter sleeve 3 is housed inside the cylindrical outer shell 1, with one end closed and the other end open and facing the refrigeration oil outlet 4. The filter sleeve 3 can be made of metal or non-metal materials with good corrosion resistance and certain mechanical strength, such as stainless steel, copper, nylon, etc. The filter sleeve 3 is provided with several holes or slits for filtration (not shown in the figure). The size and distribution of these holes or slits are designed according to the particle size of the impurities to be filtered in order to achieve the best filtration effect.

[0028] The shock-absorbing sleeve 2 is fitted outside the filter sleeve 3, with one end closed and the other end open and facing the refrigeration oil outlet 4. The material of the shock-absorbing sleeve 2 can be one or more of the following: rubber, spring steel, and damping alloy. Figure 4 As shown, the damping sleeve 2 has several through holes 21. The size, shape, and distribution of these through holes 21 can be designed according to actual needs. For example, the diameter of the through holes 21 can be set to 1mm-10mm, the number of through holes 21 can be set to 10-100, and the shape of the through holes 21 can be circular, elliptical, or other irregular shapes. The presence of the through holes 21 can change the flow path of the refrigeration oil when it flows through the damping sleeve 2, forming a damping effect, dissipating vibration energy, and thus reducing vibration transmission.

[0029] An end cap 6 is located at one end of the cylindrical outer shell 1, and has a structure that mates with the cylindrical outer shell 1, the filter sleeve 3, and the shock-absorbing sleeve 2 to fix the filter sleeve 3 and the shock-absorbing sleeve 2 inside the cylindrical outer shell 1. The end cap 6 can be fixed to the cylindrical outer shell 1 by means of bolts or welding to ensure the reliability and sealing of the connection.

[0030] The working principle of this utility model is as follows:

[0031] When the refrigeration oil enters the vibration-damping refrigeration oil filter from the refrigeration oil inlet 5, it will first flow through the damping sleeve 2. Since the damping sleeve 2 is provided with several through holes 21, the flow path of the refrigeration oil will be changed, thereby forming a damping effect and dissipating some of the vibration energy.

[0032] Next, the refrigeration oil flows from the opening of the damping sleeve 2 into the annular space between the damping sleeve 2 and the filter sleeve 3, and flows through the holes or gaps on the filter sleeve 3, thereby achieving filtration of the refrigeration oil. The filtered refrigeration oil will converge at the opening of the filter sleeve 3 and finally flow out from the refrigeration oil outlet 4.

[0033] The vibration-damping refrigeration oil filter of this utility model, by fitting a vibration-damping sleeve 2 over the filter sleeve 3 and providing a through hole 21, allows the refrigeration oil to pass through the vibration-damping sleeve 2 before filtration, which can effectively reduce vibration and noise while ensuring the filtration effect of the refrigeration oil.

[0034] The end cap 6 includes at least one annular component for fixing and sealing the filter sleeve 3 and the shock-absorbing sleeve 2. Through the fixing and sealing action of the annular component, the filter sleeve 3 and the shock-absorbing sleeve 2 can be more reliably fixed and sealed, preventing refrigerant oil leakage, ensuring the normal operating pressure of the filter, and improving the reliability and service life of the filter.

[0035] The filter sleeve 3 is equipped with multiple layers of composite filter material. By combining different filter materials, impurities and contaminants of different sizes can be intercepted more effectively, improving filtration accuracy and efficiency, ensuring the purity of the refrigeration oil, and extending the service life of the equipment.

[0036] The material of the damping sleeve 2 is selected from one or more of rubber, spring steel, and damping alloy. By using damping materials, vibration energy can be better absorbed, vibration amplitude can be reduced, the impact of vibration on equipment and the surrounding environment can be reduced, and the stability and reliability of equipment operation can be improved.

[0037] The cylindrical outer shell 1 is made of either stainless steel or aluminum alloy. This improves the shell's strength and corrosion resistance, enabling it to withstand higher pressures and harsher working environments, thus extending the filter's service life.

[0038] In summary, this novel vibration-damping refrigeration oil filter, through its structural design of placing the vibration-damping sleeve outside the filter sleeve, and the selection and optimization of materials for each component, effectively solves the problems of insufficient vibration and noise reduction performance, inconvenient installation and maintenance, and limited functionality in existing technologies, providing a refrigeration oil filtration solution that is simple in structure, reliable in performance, and easy to maintain.
