[0028] The specific embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0029] Please refer to Figs. 1 to 3 The present application provides a kind of compressor device, the compressor device includes chassis 10, compression assembly 20, cooling assembly 30 and separation assembly 40.

[0030] Specifically, the base frame 10 has a first surface and a second surface opposite in the first direction; the compression assembly 20 includes a motor 230 mounted on the first surface and at least one compressor, all of which are connected in series, and the motor 230 is connected to one of the compressors to provide power required to drive the compressor to operate. The cooling assembly 30 includes a first cooling unit 31 and a second cooling unit 32 mounted on the first surface, the first cooling unit 31 is used to cool the gas before entering the compressor, and the second cooling unit 32 is used to cool the gas after compression. Among them, the first cooling unit 31 includes a first cooler 311 and a second cooler 312, the first cooler 311 is located above the second cooler 312 and is connected in parallel with the second cooler 312 through a connecting pipe 50, and the gas inlet end of the first cooler 311 is connected with a docking pipe 60. The separation assembly 40 includes a first separation unit 41 and a second separation unit 42 mounted on the first surface, the first separation unit 41 is connected in series between the first cooling unit 31 and the compressor for separating the gas before entering the compressor, and the second separation unit 42 is connected in series between the compressor and the second cooling unit 32 for separating the gas after compression.

[0031] In the compressor device of the present application, the first cooling unit 31 is used to cool the gas to be processed to reduce the inlet temperature of the gas, and the first separation unit 41 is used to separate the cooled gas, and then the separated gas is introduced into the compressor for compression processing, and then the compressed gas is introduced into the second cooling unit 32 for cooling, and finally the second separation unit 42 is used to separate the compressed gas again, and the separated gas is introduced into another device, so as to realize the conveying of the gas from one device to another device. That is, the first cooler 311 and the second cooler 312 are connected in parallel to cool the gas to be processed, so as to quickly reduce the inlet temperature of the gas before entering the compressor, which can effectively improve the compression efficiency, and the volume of the cooled gas is reduced, so that the compressor can convey more gas under the same conditions, so as to effectively expand the range of processing gas volume, and the second cooling unit 32 is used to cool the compressed gas again to absorb a large amount of heat generated during compression, thereby reducing the power required in the next compression, which is beneficial to save power consumption. In addition, the motor 230, the compressor, the first cooling unit 31, the second cooling unit 32, and the first separation unit 41 and the second separation unit 42 are detachably mounted on the first surface of the base frame 10 in a modular manner, which can realize separate installation or disassembly, and is more convenient for workers to install and increase configuration, which is beneficial to reduce labor intensity, and can also make the structure more compact and reduce the space occupancy.

[0032] Exemplarily, in order to ensure the stability of installation and the demand of subsequent increase configuration, it is necessary to ensure that the base frame 10 has sufficient structural strength to prevent deformation or collapse after the installation of the motor 230, the compressor, the first cooling unit 31, the second cooling unit 32, and the first separation unit 41 and the second separation unit 42. For this purpose, the base frame 10 in the present embodiment can be made of a metal material (such as channel steel, I-beam, etc.) with high bending strength and carrying capacity.

[0033] In addition, in order to facilitate the installation of the motor 230, the compressor, the first cooling unit 31, the second cooling unit 32, and the first separation unit 41 and the second separation unit 42, etc., corresponding brackets (not shown) are welded on the first surface of the base frame 10 to provide support for local fixation. Meanwhile, pre-embedded part hole positions are also reserved on the second surface of the base frame 10, so that pre-embedded parts can be installed at the pre-embedded part hole positions, thereby ensuring firm fixation with the ground.

[0034] Exemplarily, the first separation unit 41 is used to separate the gas before entering the compressor to remove impurities in the gas, improve the purity of the gas, and prevent impurities in the gas from entering the compressor, thereby causing damage to the compressor. The second separation unit 42 is used to separate the compressed gas, and also removes impurities in the compressed gas to improve the purity of the gas and prevent impurities in the gas from entering the next device. For this purpose, the first separation unit 41 and the second separation unit 42 can use the same structure separation element, or different structure separation element, which is not limited.

[0035] Exemplarily, the second cooling unit 32 is used to cool the gas after compression processing. For this purpose, the second cooling unit 32 can be composed of a plurality of coolers in series, and the specific number can be determined according to the actual situation. For example, if the heat generated during compression can be quickly cooled by using one cooler, the second cooling unit 32 can be one cooler; if the heat generated during compression is too much and cannot be quickly cooled by using one cooler, the second cooling unit 32 can be composed of two or more than two coolers in series to form a step-by-step cooling mode to cool the gas.

[0036] In actual application, the second cooling unit 32 adopts two coolers in series, which are the third cooler 321 and the fourth cooler 322. The third cooler 321 is connected with the fourth cooler 322 in series through the first pipeline, and the air inlet end of the third cooler 321 is connected with the second separation unit 42. That is, the gas compressed by the compressor is introduced into the second separation unit 42, and after the separation of the second separation unit 42, the gas is first introduced into the third cooler 321 for cooling, and then introduced into the fourth cooler 322 for cooling, and finally the cooled gas is introduced into the second separation unit 42 for separation. In this way, the gas is cooled by adopting the series connection of the coolers, so as to gradually reduce the temperature of the gas, thereby ensuring the compression efficiency, and at the same time, the temperature in the compressor shell is reduced, which is beneficial to improve the operation performance and service life of the compressor.

[0037] In an embodiment, the first separation unit 41 includes a first separator 411 connected with the connecting pipeline 50 through the second pipeline 70, and the air outlet end of the first separator 411 is connected with the air inlet end of the compressor through the third pipeline 100. The first vent valve 110 is arranged on the three pipelines. The first separator 411 is used for separating the gas before the compressor. The second separation unit 42 includes a second separator 422 and a third separator 423. The second separator 422 is connected in series between the compressor and the third cooler 321. The air inlet end of the third separator 423 is connected with the air outlet end of the fourth cooler 322 through the fourth pipeline 120, and the air outlet end of the third separator 423 is connected with the fifth pipeline 130 for connecting external equipment, so as to introduce the treated gas into the external equipment.

[0038] That is, by connecting the second pipeline 70 with the connecting pipeline 50, the gas cooled by the first cooler 311 and the second cooler 312 is introduced into the first separator 411 through the second pipeline 70, and then the gas separated from the first separator 411 is introduced into the compressor for compression treatment by using the pipe fitting. Then, the second separator 422 is used for secondary separation of the compressed gas, so that the impurities mixed in the compressed gas are preliminarily separated, and then the gas is sequentially cooled by the third cooler 321 and the fourth cooler 322. Finally, the third separator 423 is used for re-separation of the cooled gas, and the gas is delivered to the external equipment. In this way, the gas before compression is separated by the first separator 411 to remove the impurities in the gas, improve the purity of the gas, prevent the impurities in the gas from entering the compressor, thereby causing damage to the compressor, and at the same time, the gas from the compressor is separated by the second separator 422, and the gas cooled by the third cooler 321 and the fourth cooler 322 is separated by the third separator 423, so as to improve the purity of the gas and prevent the impurities in the gas from entering the next equipment.

[0039] For example, the first vent valve 110 is arranged on the third pipeline 100 and is interlocked with the pressure gauge in the instrument box 240, so that when the compressor stops working or the system pressure exceeds the set value during operation, the first vent valve 110 is automatically opened to release the excess pressure to the atmosphere, thereby preventing the system pressure from being too high and protecting the compressor and related pipelines.

[0040] In an embodiment, the second pipeline 70 is provided with a filter 80 and a first check valve 90, and the filter 80 is used to filter the gas flowing to the first separator 411.

[0041] For example, impurity particles may be mixed in the gas cooled by the first cooler 311 and the second cooler 312, and part of the impurity particles cannot be removed by the separation of the first separator 411. If the impurity particles are not filtered and then introduced into the compressor for compression treatment, the compressor may be damaged. To this end, the filter 80 is arranged on the second pipeline in the embodiment, so that the gas is first filtered by the filter 80 and then introduced into the first separator for separation, thereby removing the impurity particles and preventing the impurity particles in the gas from entering the compressor and damaging the compressor. It should be noted that the filter 80 in the embodiment is a Y-type filter 80, and the particle size of the solid particles filtered by the filter 80 is between 80-90 mesh.

[0042] In addition, the first check valve 90 arranged on the second pipeline is used to prevent backflow of the gas. For example, when the compressor stops working, the first check valve 90 is closed to prevent the gas from flowing back from the first separator 411 to the first cooler 311 or the second cooler 312, thereby avoiding equipment failure or safety accidents. When the compressor is working normally, the first check valve 90 is open to allow the cooled gas to flow to the first separator 411 for separation.

[0043] In an embodiment, the second check valve 150 is connected to the end of the fifth pipeline 130 away from the third separator 423, and the second vent valve 140 is further connected to the third pipeline 100. That is, the second check valve 150 is arranged on the fifth pipeline 130 to allow the compressed gas to flow to the external equipment without backflow, thereby ensuring the safety of the pipeline. The second vent valve 140 is interlocked with the pressure gauge in the instrument box 240, so that when the compressor stops working or the system pressure exceeds the set value during operation, the second vent valve 140 can be automatically opened to release the excess pressure to the atmosphere, thereby preventing the system pressure from being too high and protecting the compressor device and related pipelines.

[0044] In an embodiment, the cooling assembly 30 further comprises a cooling fan 160 connected with the fourth cooler 322 for cooling the cooling medium in the fourth cooler 322. In this way, the cooling fan 160 is used to quickly discharge the hot air in the fourth cooler 322 after heat exchange, thereby cooling the cooling medium in the fourth cooler 322, which is beneficial to improve the cooling effect of the fourth cooler 322. It should be noted that the cooling fan 160 is a axial flow fan, but is not limited thereto.

[0045] In an embodiment, the crankcase 170 is further provided in the crankcase 170, and the compressor comprises a first compressor 21 and a second compressor 22, the first compressor 21 and the second compressor 22 are connected, the motor 230 is connected with the second compressor 22 through the crankshaft, and the air inlet end of the first compressor 21 is connected with the first separation unit 41, and the air outlet end of the second compressor 22 is connected with the second separation unit 42. In this way, the crankcase 170 is arranged between the first compressor 21 and the second compressor 22, and the first compressor 21 and the second compressor 22 are drivenly connected through the crankshaft in the crankcase 170, and then the motor 230 is connected with the second compressor 22, so that when the motor 230 drives the second compressor 22 to work, the first compressor 21 is also driven to work.

[0046] In an embodiment, the power pump 180 is further provided, the power pump 180 is installed on the first surface and located below the second compressor 22, and is used for pumping external lubricating oil into the second compressor 22 for lubrication. In this way, the power pump 180 can pump external lubricating oil into the second compressor 22 to lubricate the moving parts inside the second compressor 22, realizing separate supply of lubricating oil for the second compressor 22, having better lubrication effect, and being beneficial to improve the compression efficiency.

[0047] In an embodiment, the first vent pipe 190 and the third vent valve 200 are further provided, one end of the first vent pipe 190 is connected with the first compressor 21, and the third vent valve 200 is arranged on the first vent pipe 190 and used for controlling the conduction or closing of the first vent pipe 190. In this way, when the first compressor 21 stops working or the system pressure exceeds the set value during operation, the third vent valve 200 is automatically opened to release the excess pressure to the atmosphere, preventing the system pressure from being too high, and protecting the first compressor 21 and related pipelines.

[0048] In one embodiment, a second venting pipeline 210 and a fourth venting valve 220 are further included, one end of the second venting pipeline 210 is connected with the second compressor 22, the other end is connected with the fourth cooler 322, and the fourth venting valve is arranged on the second venting pipeline 210 and is used for controlling the opening or closing of the second venting pipeline 210. In this way, when the second compressor 22 stops working or the system pressure exceeds the set value during operation, the fourth venting valve 220 is automatically opened to release the excess pressure to the atmosphere, so as to prevent the system pressure from being too high and to protect the second compressor 22 and the related pipeline.

[0049] In one embodiment, the liquid level meters 250 are connected to the first separator 411, the second separator 422 and the third separator 423, so that the staff can know the liquid level of the cooling medium in the first separator 411, the second separator 422 and the third separator 423 in time by observing the liquid level change on the liquid level meters 250.
