Description

Technical Field

[0001] The present disclosure relates to the technical field of air compressors, and in particular to a cooling system for an air compressor aftercooler. Background Art

[0002] The air compressor aftercooler is a key component for cooling the exhaust gas of the air compressor. The aftercooler is prone to dust accumulation and clogging during long-term use, which reduces the heat dissipation efficiency of the air compressor equipment, causing the air compressor equipment to overheat and the system to alarm and shut down, seriously affecting the normal use of the equipment and the stability of the system operation.

[0003] Since dust accumulation in the aftercooler is a continuous accumulation process, the heat dissipation efficiency of the aftercooler cannot be improved in time during the operation of the air compressor. Most of the related technologies use the method of regularly disassembling the aftercooler for manual cleaning to maintain the long-term effective use of the aftercooler. However, the manual cleaning process is cumbersome and inconvenient, the cleaning cost is high, and it is still impossible to reasonably deal with the phenomenon of continuous dust accumulation in the aftercooler. Therefore, how to design a low-cost and easy-to-use cooling device to improve the heat dissipation efficiency of the air compressor aftercooler is an urgent problem to be solved in this field.

DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the actual upper and lower directions of the relevant components when in use. Figures 2 to 4 , the upper and lower directions shown in the figure are the actual upper and lower directions when the cooling device is used. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another element, and do not have order and importance.

[0028] like Figure 1 As shown, the present disclosure exemplarily provides a cooling system for an air compressor aftercooler, the cooling system comprising an aftercooler 1, a cooling device 2, an air source 3, a temperature sensing element 4 and a control unit 5. The cooling device 2 is arranged between the aftercooler 1 and the air source 3, and is used to provide cold air to the aftercooler 1; the temperature sensing element 4 is arranged on the aftercooler 1, and is used to detect the temperature value of the aftercooler 1; the control unit is arranged between the cooling device 2 and the air source 3, and can respond to the temperature value of the aftercooler 1 monitored by the temperature sensing element 4, and control the cold air in the air source 3 to blow to the aftercooler 1 through the cooling device 2.

[0029] In the above embodiment, the cooling device 2 can be arranged opposite to the surface of the aftercooler 1, and can blow cold air to the surface of the aftercooler 1 when connected to the gas source 3 to provide a cooling effect to the aftercooler 1. At the same time, a control unit 5 is arranged between the cooling device 2 and the gas source 3. The control unit 5 can control the gas connection between the gas source 3 and the cooling device 2 according to the change of the temperature value of the aftercooler 1 obtained by the temperature sensing element 4, that is, when the temperature of the aftercooler 1 is higher than the preset warning temperature, the cooling device 2 can be connected to the gas source 3 and blow the aftercooler 1 to provide cooling, or when the temperature of the aftercooler 1 is lower than the preset warning temperature, the cooling device 2 can be disconnected from the gas path of the gas source 3 to stop the blowing operation, and the overall blowing process responds automatically, which is convenient for real-time feedback control of the thermal state of the aftercooler 1.

[0030] Through the above technical scheme, the cooling device 2 is connected to the control unit 5 and the air source 3 in sequence. The control unit 5 can control the cooling device 2 to supply air to the aftercooler 1 of the air compressor according to the temperature value of the aftercooler 1 measured by the temperature sensing element 4, so as to help the aftercooler 1 to cool down, thereby effectively controlling the temperature change in the air compressor, and at the same time improving the cleanliness of the aftercooler 1 to avoid dust accumulation. The structure is simple, the purge operation has an overall automated response, and the manual cleaning cost is reduced.

[0031] In some embodiments, Figures 2 to 4 As shown, the cooling device 2 may include a bracket 21, and the bracket 21 may be provided with a plurality of beams 22 spaced apart along the up and down directions thereof. The plurality of beams 22 may be arranged in parallel, and a purge piece 23 may be provided on the beam 22, wherein the purge piece 23 on any beam 22 may be connected to the gas source 3 through a branch pipe 24.

[0032] In the above embodiment, the bracket 21 is used to support the cooling device 2 as a whole, and a plurality of beams 22 are arranged in parallel and spaced relative to the ventilation surface of the aftercooler 1, so that when the purge member 23 installed on the beam 22 is connected to the air source 3, the output airflow can constitute a purge range covering the ventilation surface of the aftercooler 1, and the distance between the bracket 21 and the aftercooler 1 is adjustable. When it is necessary to adjust the coverage area of ​​the purge airflow on the surface of the aftercooler 1, it can be achieved by adjusting the distance of the bracket 21 relative to the aftercooler 1. It should be noted that the embodiment of the present disclosure does not impose specific restrictions on the method of adjusting the distance between the bracket 21 and the aftercooler 1, including but not limited to the use of pulley slides, gear transmission or other moving methods.

[0033] For example, Figure 2As shown, a first mounting hole 221 may be provided on one side of the crossbeam 22 facing the aftercooler 1, and the purge member 23 may be detachably arranged in the first mounting hole 221, and the first mounting hole 221 may provide a stable fixed support effect for the purge member 23 when the purge member 23 is installed, so as to prevent the purge member 23 from falling off relative to the crossbeam 22 due to excessive gas flow rate in the gas source 3. At the same time, the purge member 23 may be at least partially arranged inside the crossbeam 22 through the first mounting hole 221 to save the space volume of the cooling device 2, which is conducive to setting the cooling device 2 in a narrow space. It should be noted that the embodiment of the present disclosure does not impose specific restrictions on the installation method of the purge member 23 relative to the first mounting hole 221, including but not limited to installation by connection methods such as thread, buckle or magnetic attraction, and only needs to ensure that the purge member 23 is detachably installed between the purge member 23 and the first mounting hole 221, and the stability effect is good after installation, and the conditions of resisting the gas pressure of the flowing gas in the gas source 3 are met.

[0034] In some embodiments, the number of the purge members 23 may be multiple, such as Figure 2 and Figure 4 As shown, a plurality of purge members 23 can be spaced apart on the cross beam 22 to increase the coverage of the purge airflow output by a single purge member 23 on the surface of the aftercooler 1. Meanwhile, the spaced arrangement can reduce the number of purge members 23 to be installed, thereby reducing production costs.

[0035] For example, Figures 2 to 4 As shown, any two adjacent purge members 23 on each crossbeam 22 can be arranged at equal intervals to ensure that the purge airflow output by each purge member 23 on each crossbeam 22 covers a uniform area, thereby achieving uniform purge and cleaning of the ventilation surface of the aftercooler 1.

[0036] According to some embodiments, any adjacent purge members 23 may be configured so that the formed purge airflows at least partially overlap each other on the surface of the aftercooler 1. In this embodiment, when the purge airflow output by any purge member 23 reaches the ventilation surface of the aftercooler 1, the formed airflow purge range may at least partially overlap each other with the purge range formed by the adjacent purge member 23. Due to the continuous fluidity of the airflow, the process of airflow overlapping each other continues to occur, and the airflow partially diffuses when contacting the surface of the aftercooler 1, which can effectively improve the airflow coverage rate on the surface of the aftercooler 1, thereby improving the cleaning effect of the purge member 23 on the aftercooler 1.

[0037] In some embodiments, the purge member 23 may use a fan-shaped nozzle. The gas flow output through the fan-shaped nozzle may roughly form a fan shape and form an approximately uniform circular range on the ventilation surface of the aftercooler 1, which can provide a uniform purge effect and ensure a better airflow coverage rate.

[0038] For example, Figure 3As shown, a second mounting hole 222 may be provided on one side of the crossbeam 22 away from the aftercooler 1, and the branch pipe 24 may be passed through the second mounting hole 222 and communicated with the purge member 23 inside the crossbeam 22, so that the crossbeam 22 can use the internal space to accommodate a portion of the branch pipe 24, and protect the connection between the branch pipe 24 and the purge member 23. At the same time, hiding part of the branch pipe 24 inside the crossbeam 22 can save the overall space of the cooling device 2 and prevent the pipes from being entangled or falling off. Here, the second mounting hole 222 can simply position the branch pipe 24, that is, maintain the inserted state of the branch pipe 24, without fixing the branch pipe 24, so that the branch pipe 24 can produce a slight shake driven by the gas pressure in the pipe, providing a certain shaking margin for the branch pipe 24, and preventing the branch pipe 24 from being broken at the fixed position due to excessive gas pressure.

[0039] In some embodiments, the temperature sensing element 4 may be a patch sensor, so as to be mounted on the aftercooler 1. The patch sensor can be mounted on the side wall of the air duct of the aftercooler 1 with a relatively hidden volume, and its cross-sectional area along the ventilation direction can be ignored, which can avoid generating a certain wind resistance to interfere with the circulation of the cooling airflow, and can effectively monitor the wind speed, wind direction and thermal state of the airflow, and is more convenient to use.

[0040] According to some embodiments, Figure 1 As shown, the control unit 5 may include a valve island 51 and a pulse controller 52. The valve island 51 is composed of a plurality of solenoid valves arranged in parallel, and each solenoid valve may be connected to a plurality of branch pipes 24 in a one-to-one correspondence, and is used to control the on-off of the gas path of any branch pipe 24, and the valve island 51 is electrically connected to the pulse controller 52, and may receive a pulse signal output by the pulse controller 52, so as to perform the on-off action of the solenoid valve according to the pulse signal.

[0041] In this embodiment, the signal output mode of the pulse controller 52 can be a timed continuous mode, that is, the multiple solenoid valves in the valve island 51 can be opened in sequence in a timed continuous manner, so that the process of the cooling device 2 outputting cold air can be expressed as multiple beams 22 and corresponding branch pipes 24 can be connected to the air source 3 in sequence in the up and down directions, and the purge part 23 performs a purge action on the ventilation surface of the aftercooler 1. In this output mode, the pulse signal can only open one solenoid valve at a time, that is, only one beam 22 and the purge part 23 installed thereon can output cold air at a time, and finally the aftercooler 1 can receive the purge of the cold air flow in sequence in the up and down directions. This mode can effectively avoid the formation of convection of cold air output between different beams 22, so as to weaken the cooling effect on the entire ventilation surface of the aftercooler 1.

[0042] At the same time, in some embodiments, the number of temperature sensing elements 4 can be multiple, roughly corresponding to the number of solenoid valves in the valve island 51. Specifically, when the temperature sensing element 4 detects that the temperature of the airflow output from the local surface of the aftercooler 1 is abnormal, some solenoid valves can be opened accordingly to control the relative cross beams to purge the abnormal parts of the aftercooler 1. There is no need for the cooling device 2 to perform an overall purge action, saving electricity and usage costs.

[0043] For example, Figure 1 As shown, the control unit 5 may further include a protection switch 53, which may be electrically connected to the valve island 51 and the pulse controller 52, respectively, to provide overload protection for both, thereby avoiding damage to the equipment under abnormal conditions and reducing maintenance costs.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0046] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
