TECHNICAL FIELD

[0001] The utility model relates to a cold and hot split cavity air compressor. BACKGROUND

[0002] With the gradual development of the industrialization of society, the air compressor as the power equipment of the compressed air source has developed along with the development of the automation industry. For a long time, the country advocates sustainable development and green development, promotes energy saving and emission reduction, and therefore puts forward many encouraging policies to encourage enterprises to produce low-carbon.

[0003] At present, compressed air has become the second largest safe energy source next to electricity and is widely used in various industries. According to incomplete statistical analysis, 95% of the existing companies in China will apply compressed air, so the development trend of compressed air machine equipment in China is very large.

[0004] The existing air compressor is that the air intake system, the transmission system, the separation system and the cooling system are sequentially placed in the whole machine box, and the compressed gas is transported through the pipeline connection. The four systems are not isolated and are only placed together. The excess energy generated by the compressed gas is dissipated in the form of heat in the whole box. The cooling system gas exchange process is discharged outside the box or enters the transmission system with the air intake system.

[0005] The air intake system, the transmission system, the separation system and the heat dissipation system of the traditional air compressor are arranged in the same shell. Because compressed gas is generated, a large amount of heat is generated in the transmission system. The heat is dissipated in the whole air compressor box through the surface of the transmission system and the separation system shell, which leads to the cooling air introduced from the outside. After being heated, the cooling effect is greatly discounted in the heat exchange in the cooling system. At the same time, it also affects the air intake system, so that the heated gas enters the transmission system, resulting in a decrease in the compression work efficiency. INVENTION CONTENTS

[0006] The main technical problem to be solved by the utility model is to provide a cold and hot split cavity air compressor. The air compressor system layout adopts a cold and hot split cavity form to realize independent air intake heat dissipation and independent air intake functions. At the same time, the air intake system and the power distribution system are combined into an integrated box structure, so that the overall structure is more compact.

[0007] In order to solve the above technical problems, the utility model provides a cold and hot split cavity air compressor, which comprises: an air intake and power distribution integrated box, a power distribution system, an air filter assembly, an air flow channel, an air compression and transmission system, and an oil and gas separation device for treating mixed gas. The compressed gas and lubricating oil formed after separation enter the cooling system for cooling.

[0008] The cooling system comprises a partition plate, a cooler and a cooling fan; the cooled lubricating oil passes through an oil filter device and returns to the transmission system; the cooled compressed gas enters the post-processing end from the exhaust port of the cooler; the partition plate is used for separating the cooling system from the oil-gas separation device and the transmission system;

[0009] It also comprises a ventilation fan arranged according to the position of the heat source.

[0010] In a preferred embodiment, the air entering the air intake and distribution integrated box is divided into three paths: the first path enters the air filter assembly, and then enters the transmission system through an air flow channel; the second path is used for cooling the transmission system; and the third path gas acts on the power distribution system to remove the heat generated by the current resistance.

[0011] In a preferred embodiment, the cooling fan adopts top air suction, and the gas is sucked into the cooler and discharged from the top after heat exchange.

[0023] Reference Figures 1-7 The embodiment provides a cold and hot cavity separation air compressor, which comprises: an air inlet system 1 formed by an air inlet and power distribution integrated box 2, a power distribution system 3 and an air filter assembly 4, an air flow channel 5, an air compression and transmission system 6, and an oil-gas separation device 7 for treating mixed gas, compressed gas and lubricating oil formed after separation enter a cooling system 8 for cooling,

[0024] The cooling system comprises a partition plate 9, a cooler 10 and a cooling fan 11; after cooling, the lubricating oil passes through an oil filter device 12 and returns to the transmission system 3; the compressed gas after cooling enters a post-processing end from the exhaust port of the cooler 10; the partition plate 9 is used for separating the cooling system from the oil-gas separation device 7 and the transmission system 6;

[0025] Further comprising a ventilation fan arranged according to the position of the heat source.

[0026] Low temperature air enters the air intake and power distribution integrated box 2 from outside, the low temperature air is divided into three paths, the first path enters the air filter assembly 4, passes through the air flow channel 5, and finally enters the transmission system 6 to compress and work and transmit; in the process that the low temperature air enters the transmission system 6 through the multi-level conveying structure, the noise generated by compression and work can be effectively reduced. The second path of low temperature gas can dissipate heat for the transmission system 6, because most of the mechanical energy is converted into heat energy in the process of compression and work, so a large amount of heat is generated on the surface of the transmission system 6 shell, and therefore the second path of low temperature gas can dissipate the heat; the third path of low temperature gas acts on the power distribution system 3, and the heat energy generated by current resistance can affect input power, and under the action of low temperature airflow, the heat can be taken away. The entire air intake system 1 is designed to isolate the influence of internal noise and high temperature, the low temperature state of the gas used for air intake compression and air intake heat dissipation enters the internal machine to act, and the internal machine is in a relatively low temperature condition, so that the air compressor machine can run more smoothly, energy saving and emission reduction are effectively promoted, and the sound insulation and noise reduction effects are achieved; the air intake and power distribution integrated box 2 designed in the air intake system 1 is multi-element combined, so that the structure is more compact, the low temperature air intake efficiency is improved, and cost reduction and efficiency increase are achieved.

[0027] The compressed oil-gas mixture enters the separation system to be coarsely separated and finely separated, the high-temperature lubricating oil after coarse separation and the high-temperature compressed gas after fine separation enter the cooling system 8, the internal cooler 10 of which adopts an external layout, and the entire cooling system 8 is separated from the internal separation system 7 and the transmission system 6 by the partition plate 9, so as to prevent the internal heat source from affecting the heat dissipation efficiency; the top of the cooling fan 11 adopts a suction form, and external low-temperature gas is sucked into the cooler 10 for heat exchange and then discharged from the top. The entire cooling system 8 is independent and integrated, so that the external low-temperature gas can smoothly enter, the heat exchange efficiency is improved, the heat exchange material of the cooling system 8 can be simplified, and the use cost is reduced; the high-temperature gas after heat exchange also expands and rises, and is discharged under the driving of the cooling fan, so that the operation resistance of the cooling fan 11 is reduced, and the power consumption of the fan is reduced; meanwhile, the layout form of the entire cooling system 8 also effectively reduces the noise propagation of the transmission system 6. Finally, the cooled compressed gas is discharged from the cooler 10 exhaust port and sent to the post-processing.

[0028] The transmission system 6 and the separation system 7 of the entire machine are provided with the auxiliary cooling ventilating fan 13, which continuously transports heat to the outside, so as to ensure the stable operation of the system.
