Description

Technical Field

[0001] This application relates to the field of compressed air station technology, and in particular to an integrated air compressor station. Background Technology

[0002] A complete compressed air supply system, or air station, typically includes not only the air compressor unit but also integrated air purification components (such as oil-gas separators, air dryers, etc.).

[0003] Traditional stationary compressed air stations typically employ a "split-type" or "assembled-type" design concept. Split-type stations, such as the multi-purpose medium-pressure oil-free screw air compressor with stable air supply disclosed in patent publication CN223447234U, and assembled-type stations, such as the energy-saving screw air compressor disclosed in patent publication CN221482159U, all utilize large components like the compressed gas production assembly (including the compressor head and the motor driving it), oil-gas separator, air tank, and electrical control cabinet. These large components are treated as independent equipment units, connected and assembled on-site via pipelines and cables. This layout has several inherent drawbacks: First, it needs to occupy a large amount of floor space; Secondly, the complex on-site installation and pipeline connection work leads to long construction periods and high installation costs.

[0004] Furthermore, the scattered component layout results in poor overall equipment integrity, making it extremely inconvenient to relocate or modify the equipment.

[0005] When configuring a compressed air supply system, the compressed gas production components, oil-gas separator, and electrical control cabinet are usually fixed and matched according to the required power. The selection of this power depends on the pressure "peak" and "pressure demand," meaning that the power must be sufficient for the system to respond quickly to changes in flow rate. The size of the air tank needs to meet the requirements of "peak shaving and valley filling," allowing you to choose an air compressor with a slightly smaller displacement (lower power) so that its average exhaust capacity can meet the total demand.

[0006] While the selection of power and the size of the air storage tank are related, the factors considered are different. Therefore, it is advisable to pre-integrate the compressed gas production components, oil-gas separator, and electrical control cabinet according to power type to form an integrated air compressor station. When configuring the compressed air supply system, first select the aforementioned integrated air compressor station with an appropriate power based on requirements, and then select an air storage tank of the required size for configuration; even later, air drying devices can be added as needed. This reduces the site area occupied by the compressed air supply system and shortens the on-site installation period and costs. Utility Model Content

[0007] The purpose of this application is to propose an integrated air compressor station that solves the problems of traditional fixed compressed air stations, which typically adopt a "split" or "assembled" design, resulting in large space occupation, long on-site installation period, and high installation cost.

[0008] To achieve the above objectives, this application adopts the following technical solution: An integrated air compressor station includes: a housing with two mounting windows on its top; a compressed air production assembly disposed inside the housing and used to generate compressed gas; an oil-gas separator disposed inside the housing and used to separate oil from gas generated by the compressed air production assembly; a first pipeline connected at one end to the oil-gas separator and at the other end to the compressed air production assembly, used to guide the oil separated by the oil-gas separator back to the compressed air production assembly; and a second pipeline connected at one end to the oil-gas separator and at the other end to an air inlet.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the fan includes a wind-gathering shroud fixedly installed on the top of the housing and covering the first cooler or the second cooler. The wind-gathering shroud is provided with an installation port facing the installation window, and an electric fan blowing air toward the installation window is provided on the installation port.

[0014] Based on the above scheme and as a preferred embodiment: the oil-gas separation assembly includes: a separation tank body, which is vertically disposed inside the housing; an annular section, which is disposed on the upper side inside the separation tank body, and the upper end of the annular section is fixedly connected to the top of the separation tank body, so that an annular separation channel is formed between the outer side of the annular section and the inner wall of the separation tank body; an air inlet, which is disposed outside the separation tank body and extends from the outside of the separation tank body into the separation channel, and the air inlet is connected to the air outlet of the compressed air production assembly; an oil outlet, which is disposed outside the separation tank body and extends from the outside of the separation tank body to the lower side inside the separation tank body, and the oil outlet is connected to the first pipeline; and an air outlet, which is disposed outside the separation tank body and extends from the outside of the separation tank body to the inner side of the annular section, and the air outlet is connected to the second pipeline.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: a baffle plate is provided on the lower part of the inner side of the annular segment, and a vent hole is provided on the baffle plate; the vent interface includes a vent pipe, one end of which passes through the body of the separator and extends upward from the lower side of the annular segment, and the vent pipe passes through the baffle plate and extends to the upper part of the inner side of the annular segment.

[0016] Based on the above scheme and as a preferred embodiment of the above scheme: a first filter is provided on the air outlet, and the first filter is connected in series between the air outlet and the second pipeline; a second filter is connected in series at one end of the second pipeline near the air inlet.

[0017] Based on the above scheme and as a preferred embodiment of the above scheme: the oil outlet includes an oil outlet pipe, which enters the interior of the separator body from the middle of the separator body and extends downward to the lower side of the separator body; the air inlet extends laterally into the interior of the separator body so that the air inlet direction of the air inlet is tangent to the separation channel.

[0018] To address the issues of traditional stationary compressed air stations, which typically employ a "split-type" or "assembled-type" design, resulting in large footprints, long on-site installation periods, and high installation costs, this application offers the following advantages: When using this system, the appropriate air compressor integrated station model is generally selected based on the power requirements (usually referring to the power of the compressed air production components). (Different power outputs correspond to different models, and power variations result in different volume changes, which do not affect the system's principle or structural layout.) Then, the appropriate air tank size is selected based on the requirements. The air tank's inlet is then connected to the air inlet of the integrated air compressor station. The air-using equipment connects to the air tank and draws air from its outlet. The advantages of separating the air tank for separate configuration are twofold: first, it avoids integrating a fixed-size air tank into the integrated air compressor station, expanding the range of air tank options and better adapting to different air usage configurations; second, it avoids the problem of an excessively large integrated air compressor station due to a large-capacity tank, which would abnormally occupy cabinet space or cause unnecessary waste of space, hindering the miniaturization of the integrated air compressor station and the overall air production system.

[0019] The working logic of this integrated air compressor station is as follows: the compressed air production component operates and produces compressed gas; however, due to the inherent working principle of the compressed air production component (oil-lubricated air compressor), the compressed gas output from the compressed air production component contains a large amount of oil. Therefore, the compressed air production component is connected to an oil-gas separator component, which separates the oil from the compressed gas produced by the compressed air production component. The separated oil accumulates in the oil-gas separator component and, under its own pressure, flows back to the compressed air production component through the first pipeline for recycling. The separated oil-free gas (compressed gas) is transported through the second pipeline to the air inlet (connected to the air tank) and temporarily stored in the air tank. External air-consuming equipment or systems can connect to the air tank through pipelines and use the air.

[0020] It is important to note that this integrated air compressor station achieves a high degree of integration through the aforementioned design methods, saving installation space in the air-using area, particularly in the horizontal plane, which facilitates equipment miniaturization. Furthermore, the active cooling of the fan effectively reduces the internal temperature, preventing component overheating and improving system reliability and lifespan. The layered layout, in addition to optimizing space, also promotes airflow from bottom to top, enhancing heat dissipation efficiency. Traditional designs face difficulties in heat dissipation after miniaturization, but the heat dissipation method described above ensures effective cooling while maintaining a compact structure, and improves the cooling capacity for both oil and compressed gas.

[0021] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0027] Traditional stationary compressed air stations typically employ a "split-type" or "assembled-type" design, which results in significant space requirements, long on-site installation periods, and high installation costs. Therefore, it's advisable to pre-integrate the compressed gas production components, oil-gas separator, and electrical control cabinet according to power type to form an integrated air compressor station. When configuring the compressed air supply system, first select an integrated air compressor station with an appropriate power based on requirements, then choose an air storage tank of the appropriate size; even later, air drying devices can be added as needed. This reduces the space occupied by the compressed air supply system and shortens the on-site installation period and costs.

[0028] See Figures 1-7 This application discloses an integrated air compressor station, which is mainly used for producing compressed air. Of course, it can also be used for the compression of other gases using the same structural principle.

[0029] In the embodiments of this disclosure, such as Figures 1-4As shown, this integrated air compressor station includes a housing 100, a compressed air production assembly 200, an oil-gas separation assembly 300, a first pipeline 400, a second pipeline 500, a first cooler 600, a second cooler 700, and a fan 800. The housing 100 has two mounting windows 102 on its top. The compressed air production assembly 200 is located inside the housing 100 and is used to generate compressed gas. The oil-gas separation assembly 300 is located inside the housing 100 and is used to separate oil and gas from the compressed gas generated by the compressed air production assembly 200. One end of the first pipeline 400 is connected to the oil-gas separation assembly 300, and the other end is connected to the compressed air production assembly 200, and it is used to guide the oil separated by the oil-gas separation assembly 300 back to the compressed air production assembly 200. One end of the second pipeline 500 is connected to the oil-gas separation assembly 300, and the other end is connected to an air inlet 112, and it is used to separate oil and gas. The compressed gas separated from component 300 is guided to gas inlet 112; the first cooler 600 is provided at one of the installation windows 102, and the first cooler 600 is provided with a first cooling channel 601, which is connected in series to the first pipe 400; the second cooler 700 is provided at the other installation window 102, and the second cooler 700 is provided with a second cooling channel 701, which is connected in series to the second pipe 500; there are two fans 800, both of which are located at the top of the housing 100, so as to cool the first cooler 600 and the second cooler 700 by blowing air outward through the fans 800.

[0030] When using the air compressor integrated station, select the appropriate model based on the power requirements (usually referring to the power of the compressed air production component 200). (Different power outputs correspond to different models, and power variations result in different volume changes, which do not affect the principle and structural layout of the solution.) Then, select the appropriate size of the air tank according to the requirements. Connect the air tank's inlet to the air inlet 112 of the air compressor integrated station. Connect the air-using equipment to the air tank and draw air from its outlet. The advantages of separating the air tank for separate configuration are twofold: first, it avoids integrating a fixed-size air tank into the air compressor integrated station, expanding the range of air tank options and better adapting to different air usage configurations; second, not integrating the air tank avoids making the overall volume of the air compressor integrated station too large, causing abnormal space occupation in the housing 100 or unnecessary wasted space, which is detrimental to the miniaturization of the air compressor integrated station and the overall air production system.

[0031] The working logic of this integrated air compressor station is as follows: the compressed air production component 200 operates and produces compressed gas; however, due to the necessity of the working principle of the compressed air production component 200 (an oil-lubricated air compressor), the compressed gas output by the compressed air production component 200 contains a large amount of oil. Therefore, the compressed air production component 200 is connected to the oil-gas separator component 300, which separates the oil from the compressed gas produced by the compressed air production component 200. The separated oil accumulates in the oil-gas separator component 300 and, under its own pressure, flows back to the compressed air production component 200 through the first pipeline 400 for recycling. The separated oil-free gas (compressed gas) is then transported through the second pipeline 500 to the air inlet 112 (connected to the air storage tank) and temporarily stored in the air storage tank. External air-consuming equipment or systems can connect to the air storage tank and use the gas through pipelines.

[0032] The integrated air compressor station of this application has several advantages. First, by installing two fans 800 at the top of the housing 100, a large volume of air is discharged to the outside of the housing 100 for heat dissipation. This also encourages a large amount of external cooling air to enter and pass through the housing 100, thus ensuring sufficient heat dissipation. Even with a compact overall structure, there is no problem with insufficient heat dissipation. Second, by simultaneously installing a first cooler 600 and a second cooler 700 at the top of the housing 100, with the first cooler 600 cooling the oil on the first pipeline 400 and the second cooler 700 cooling the compressed gas on the second pipeline 500, the use of two "coolers" increases the heat exchange area and extends the cooling path and time for both the oil and compressed gas, thereby improving the cooling effect. Third, by adjusting the traditional single cooler or no cooler configuration to two "coolers" simultaneously arranged at the top of the housing 100, the limitation of traditional layouts in arranging large-area cooling devices in limited space is overcome.

[0033] It is important to note that this integrated air compressor station achieves a high degree of integration through the aforementioned design methods, saving installation space in the air-using area, particularly in the horizontal plane, which facilitates equipment miniaturization (such as the KS model). Furthermore, the active cooling of the 800 fan effectively reduces the internal temperature, preventing component overheating and improving system reliability and lifespan. The layered layout, in addition to optimizing space, also promotes airflow from bottom to top, enhancing heat dissipation efficiency. Traditional designs face difficulties in heat dissipation after miniaturization, but the aforementioned structure ensures effective heat dissipation while maintaining a compact structure, and improves the cooling capacity for both oil and compressed gas.

[0034] In the embodiments of this disclosure, such as Figure 4As shown, considering that the gas inlet 112 is typically used to connect to a gas storage tank, the gas inlet 112 is located in the housing 100 and extends from the inside of the housing 100 to the outside, facilitating the direct and quick connection of external gas storage tank pipelines to the gas inlet 112 outside the housing 100. When fixing the gas inlet 112, the gas inlet 112 can pass through one of the uprights 103 and be fixedly connected to it.

[0035] In the embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the box 100 has a bottom 105 and a top 101, both of which are rectangular, with the top 101 located directly above the bottom 105. Several columns 103 (such as square tubes) are provided between the bottom 105 and the top 101. The upper end of the column 103 is rigidly connected to the top 101, and the lower end is rigidly connected to the bottom 105. The columns 103 are located at the four corners of the bottom 105 and the top 101. Around the bottom 105 and the top 101, there are openable and closable doors 110 between each pair of adjacent columns 103 to close the area between the bottom 105 and the top 101.

[0036] This integrated air compressor station utilizes a rectangular parallel arrangement of the bottom 105 and top 101 of the housing, rigidly connected by columns 103 at the four corners to form a stable frame. The columns 103 (such as square tubing) provide structural support, and openable / closable doors 110 are installed between each pair of columns 103, allowing the housing 100 to be closed or opened on all sides. The columns 103 provide support while enhancing the overall structural rigidity and vibration resistance, ensuring the stability of the air station during operation. The doors 110 are designed for easy daily maintenance and repair, and when closed, they provide dust (or rain) protection, adapting to various environmental conditions.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the bottom of the box 105 includes two parallel first square tubes 106. The two first square tubes 106 are connected as one unit by several second square tubes 108. A support plate 109 is provided above the first square tubes 106 to form the bottom plate inside the box 100. Two forklift holes 107 are arranged on the first square tubes 106 along the length direction.

[0038] The bottom of the housing 105 is connected to form a frame by two parallel first square tubes 106 and several second square tubes 108, with a support plate 109 on top to form a base plate. Two forklift holes 107 can be provided along the length of the first square tubes 106, facilitating the movement of the integrated air compressor station by inserting a forklift into the holes 107. A column 103 (such as a third square tube 104) can be added to the middle of both sides of the bottom of the housing 105 along its length to strengthen the support, allowing the door 110 at this location to be narrower for easier use, and also improving the overall structural stability of the housing 100.

[0039] In addition, the top of the box 101 can also form a support structure through square tubes, so that the box body 100 can be fixedly connected by welding or other means to form a high-rigidity frame, providing high strength and durability. The support plate 109 forms a flat bottom plate to provide installation support and protect the internal components. As a result, the overall structure of the box body 100 is lightweight and has a strong load-bearing capacity.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, an air inlet window 111 is provided on the lower side of the enclosure 100, such as on the door 110 at both ends of the enclosure 100 along its length. The air inlet window 111 allows external cold air to enter, preventing the fan from working too hard and facilitating heat dissipation. It also facilitates the upward flow of cooling air within the enclosure 100.

[0041] Furthermore, such as Figure 1 , Figure 3 As shown, the installation window 102 is located on the top of the box 101, as... Figure 5 As shown, the fan 800 includes a wind-concentrating shroud 801 fixedly installed on the top of the box 101 and covering the first cooler 600 or the second cooler 700. The wind-concentrating shroud 801 is provided with an installation port 802 facing the installation window 102. An electric fan 803 blowing air toward the installation window 102 is provided on the installation port 802.

[0042] When arranged within the enclosure 100, such as Figure 2As shown, the enclosure 100 also houses an electrical control cabinet 903, which is located on one side of the bottom length direction of the enclosure 100. The opening side of the electrical control cabinet 903 can face outwards, sharing one of the switch doors 110 with the enclosure 100, thereby improving ease of use and reducing equipment costs. The electrical control cabinet 903 can house control components such as frequency converters, controllers (PLCs), and switches. The compressed air production assembly 200 includes a gas compressor head 201 for compressing gas and a motor 202 for driving the gas compressor head 201. The compressed air production assembly 200 is arranged along the length direction of the enclosure 100, forming a separate row. The oil-gas separation assembly 300 and the electrical control cabinet 903 are located at both ends of a row parallel to the compressed air production assembly 200. In addition, the first cooler 600, the second cooler 700 and the fan 800 are located on the top of the housing 100, which makes the overall structure layout reasonable and compact, and there is still a relatively large operating space between them. This is conducive to airflow and heat dissipation, and reduces the heat radiation between them; and it also provides operating space for installation and maintenance.

[0043] In this embodiment of the disclosure, considering that the oil-gas separation effect is also a key factor in product quality, in order to more fully guarantee the oil-gas separation effect under the premise of compact structure and miniaturization of oil-gas separation component 300.

[0044] like Figure 6 and Figure 7 As shown, the oil-gas separation assembly 300 includes: a separation tank body 301, which is vertically (upward in the height direction) disposed inside the housing 100; an annular section 302, which is disposed on the upper side inside the separation tank body 301, and the upper end of the annular section 302 is fixedly connected to the top of the separation tank body 301, so that an annular separation channel 303 is formed between the outer side of the annular section 302 and the inner wall of the separation tank body 301; and an air inlet 306, which is disposed outside the separation tank body 301 and enters from the separation tank body 301. The air inlet 306 extends into the separation channel 303 and is connected to the air outlet of the compressed air production assembly 200; the oil outlet 307 is located outside the separator body 301 and extends from the outside of the separator body 301 to the lower side inside the separator body 301, and is connected to the first pipeline 400; the air outlet 309 is located outside the separator body 301 and extends from the outside of the separator body 301 to the inner side of the annular section 302, and is connected to the second pipeline 500.

[0045] Compressed air mixed with a large amount of oil leaves the compressed air production assembly 200 and enters the separation channel 303 through the air inlet 306. Upon entering the separation channel 303, firstly, the compressed air impacts the inner wall of the separation channel 303 at high speed, causing the oil pressure to separate from the gas and deposit downwards at the bottom of the separation tank body 301; secondly, the compressed air undergoes high-speed centrifugal flow along the separation channel 303, and during this flow, the inner wall of the separation channel 303 creates a viscosity effect on the oil, thereby promoting oil-gas separation. It is worth noting that if the oil contains particulate impurities, it can also be separated and filtered using the same principle. Furthermore, since the oil outlet 307 is located on the lower side of the tank body, the oil can be pushed towards the compressed air production assembly 200 under air pressure to establish a recycling cycle. Because the outlet port 309 extends into the inner side of the annular section 302, the annular section 302 establishes isolation and protection for the outlet port 309. The compressed air containing oil, which has a higher density, is located in the lower layer, while the compressed air above, which is oil-free (or contains a small proportion of oil), can flow out from the outlet port 309 to the outside of the separator body 301. This prevents oil droplets from being carried into the outlet pipe 310, ensuring that the output gas is drier and purer, reducing the burden on subsequent filtration. This effectively guarantees the oil-gas separation effect and facilitates miniaturization.

[0046] Furthermore, such as Figure 7 As shown, a baffle plate 304 is provided on the lower part of the inner side of the annular section 302, and a vent hole 305 is provided on the baffle plate 304. The air outlet 309 includes an air outlet pipe 310, one end of which passes through the separator body 301 and extends upward from the lower side of the annular section 302, passing through the baffle plate 304 and extending to the upper part of the inner side of the annular section 302. This further prevents oil from entering the air outlet pipe 310 and enhances the separation effect. The vent hole 305 ensures smooth gas flow and improves separation efficiency. It also prevents oil droplets from being carried into the air outlet pipe 310, ensuring that the output gas is drier and purer, reducing the burden on subsequent filtration.

[0047] Furthermore, a first filter 901 is provided on the air outlet 309, and the first filter 901 is connected in series between the air outlet 309 and the second pipeline 500 to filter the separated compressed air. This removes residual impurities and particles from the air, improves the cleanliness of the compressed air, and protects the cooler, air tank, and downstream equipment. Additionally, a second filter 902 is connected in series at the end of the second pipeline 500 near the air inlet 112.

[0048] The second filter 902 is used to remove moisture and impurities from the second pipeline 500, primarily for water removal. It removes the liquid water condensed after cooling by the second cooler 700, reducing the water content of the compressed gas at the gas-using end. Specifically, the second cooler 700 and the fan 800 can be fixedly connected as a single unit and installed at the mounting window 102 on the top of the housing 101. When processing the compressed gas, the fan 800 forces heat exchange in the second cooler 700, and combined with the extended cooling path and time of the second cooling channel 701, a rapid temperature difference dehydration effect is achieved, quickly cooling and removing a large proportion of the moisture from the compressed gas (compressed air). The liquid water condensed after cooling by the second cooler 700 is then removed by the second filter 902.

[0049] Furthermore, the oil outlet 307 includes an oil outlet pipe 308, which enters the interior of the separator body 301 from the middle and extends downwards to the lower side of the separator body, making the oil outlet 307 close to the bottom and with a gap; thus, the oil overflows the air inlet 306 and protects the air inlet 306, effectively preventing compressed air from escaping back into the compressed air production assembly 200 from the air inlet 306. By extending the air inlet 306 laterally into the interior of the separator body 301, so that the air intake direction of the air inlet 306 is tangent to the separation channel 303, centrifugal motion is effectively generated for efficient oil and water removal.

[0050] Generally, shock-absorbing pads 904 are provided between the separator body 301, the oil-gas separation component 300 and the bottom plate.

[0051] Furthermore, to ensure safe use and improve the convenience of daily maintenance, the separator body 301 is also equipped with a pressure gauge 311 for displaying internal air pressure, a pressure relief valve 312 for protecting the pressure limit, an oil inlet 313 for adding oil (the oil inlet 313 is equipped with a removable plug 314), a drain valve 315 for draining accumulated water, and a liquid level observation window 316 for observing the oil level, etc.

[0052] In summary, the integrated air compressor station features a compact and rational design, ensuring both miniaturization and efficient heat dissipation. Furthermore, it guarantees structural rigidity and ease of maintenance.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
