Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a novel air compressor. Background Technology

[0002] An air compressor is designed to increase the velocity of gas molecules, converting their kinetic energy into pressure energy, thereby increasing the pressure of compressed air. Once a certain pressure is reached, the air is discharged. Air enters through a filter, and the compressor, a screw-type unit driven by a permanent magnet synchronous motor, compresses the air. The compressed air gradually changes from a low-pressure state to a high-pressure state. Because the screw in the compressor requires lubrication with oil, high temperatures are generated during compression, carrying oil into the compressed air. Therefore, an oil-air separator separates the oil from the compressed air. The compressed air then passes through a cooler to lower its temperature, while the separated oil is also cooled and returned to the compressor screw for reuse.

[0003] The oil filter element in the existing air compressor oil-gas separator needs to be replaced after a period of use. Currently, the air compressor structure requires the entire oil-gas separator to be removed for manual replacement, which requires disassembling a large number of bolts and is time-consuming. Similarly, when the air compressor main unit needs maintenance, it also needs to be disassembled and removed manually. Therefore, in view of the above situation, there is an urgent need to develop a new type of air compressor that allows the air compressor and oil-gas separator to be moved out for easy maintenance, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a novel air compressor to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel air compressor includes a cabinet, an air compressor main unit, an oil-gas separator, a cooling fan, an air filter, a first transmission mechanism, a second transmission mechanism, an oil filter element, an oil return pipe, an air cooler, an oil cooler, and an exhaust pipe. The first and second transmission mechanisms are both installed inside the cabinet at the bottom. The first transmission mechanism is arranged in a front-to-back direction, and the second transmission mechanism is arranged in a left-to-right direction. The oil-gas separator is bolted to the first transmission mechanism, and the air compressor main unit is bolted to the second transmission mechanism. A front cabinet door is detachably installed on the front side of the oil-gas separator, and a side cabinet door is detachably installed on the right side of the air compressor main unit. The cooling fan, air filter, oil filter element, air cooler, and oil cooler are all fixedly installed... The air filter is installed inside the cabinet, and an air supply pipe connected to the air compressor main unit is installed on the air filter. The air compressor main unit is installed with an air guide pipe connected to the oil-gas separator. The cooling fan faces the air cooler and the oil cooler. The first transmission mechanism includes: a first motor, a first lead screw, a first support, a first rolling nut, a first slide rail, and a first slider. The first motor is fixed inside the cabinet. The first lead screw is rotatably connected inside the cabinet. The output shaft of the first motor is fixed to the first lead screw. A first rolling nut is installed on the first lead screw. The first rolling nut is fixed to the first support. The oil-gas separator is fixed on the first support. Two first slide rails are fixed to the bottom of the first support. The first slide rails are slidably installed on the first slider. The first slider is fixed inside the cabinet.

[0007] Preferably, the second transmission mechanism includes: a second motor, a second lead screw, a second support, a second rolling nut, a second slide rail, and a second slider. The second motor is fixed inside the cabinet, the second lead screw is rotatably connected inside the cabinet, the output shaft of the second motor is fixed to the second lead screw, a second rolling nut is installed on the second lead screw, the second rolling nut is fixed to the second support, the air compressor main unit is fixed on the second support, two second slide rails are fixed to the bottom of the second support, the second slide rails are slidably installed on the second slider, and the second slider is fixed inside the cabinet.

[0008] Preferably, a valve is installed on the top of the oil-gas separator, and the valve is connected to the air cooler through an air outlet pipe.

[0009] Preferably, the oil-gas separator has an oil outlet at its bottom, which is connected to the oil cooler via a pipe.

[0010] Preferably, the oil cooler is connected to the oil filter element via a pipe, and the oil filter element is connected to the air compressor main unit via a return oil pipe.

[0011] The beneficial effects of this utility model are as follows: When this novel air compressor is working, the air compressor main unit starts, and outside air is drawn in through the air filter inlet. The air is filtered by the air filter, and then the air compressor main unit compresses the air. During the compression process, high temperatures are generated, and oil is carried into the compressed air. Then, the air compressor main unit sends the compressed air (mixed with oil) through the air guide pipe to the oil-gas separator. The oil-gas separator separates the air and oil. Then, the compressed air is sent from the outlet pipe at the top of the oil-gas separator to the air cooler for cooling before being discharged. The oil filtered out in the oil-gas separator flows out from the oil outlet through the pipe... The oil is transported to the oil cooler, where it is cooled and then flows through a pipe into the oil filter. The oil filter removes impurities from the oil, and finally, it returns the oil to the air compressor unit via the return pipe. When maintenance is required on the air compressor unit and oil separator, the pipe joints connecting them are disconnected, the front and side cabinet doors are opened, and the first motor drives the first lead screw to rotate. The first lead screw then moves the first rolling nut and the first support, which in turn moves the oil separator out of the cabinet. Similarly, the second transmission mechanism moves the air compressor unit out from the side of the cabinet for maintenance. In summary, this invention facilitates the removal of the air compressor unit and oil separator for easy maintenance. Attached Figure Description

During compression, high temperatures are generated, and... The oil is carried into the compressed air. Then, the air compressor 2 sends the compressed air (mixed with oil) through the air guide pipe 202 to the oil-gas separator 3. The oil-gas separator 3 separates the air and oil.

[0026] Working Principle: When this new type of air compressor is working, the air compressor main unit 2 starts, and outside air is drawn in through the air filter 5 inlet. The air is filtered by the air filter 5, and then compressed by the air compressor main unit 2. During compression, high temperatures are generated, and oil is carried into the compressed air. The air compressor main unit 2 then delivers the compressed air (mixed with oil) through the air guide pipe 202 to the oil-gas separator 3. The oil-gas separator 3 separates the air and oil. The compressed air is then delivered from the outlet pipe 12 at the top of the oil-gas separator 3 to the air cooler 10 for cooling before being discharged. The oil filtered out in the oil-gas separator 3 is delivered from the oil outlet 302 through a pipe to the oil cooler 11. After being cooled in the oil cooler 11, the oil enters the oil filter element 8 through the pipeline. The oil filter element 8 filters out impurities in the oil. Finally, the oil filter element 8 sends the oil back to the air compressor main unit 2 through the oil return pipeline 9. When the air compressor main unit 2 and oil-gas separator 3 need to be repaired, the pipe joints connected to the air compressor main unit 2 and oil-gas separator 3 are disconnected, the front cabinet door 101 and the side cabinet door 102 are opened, and the first motor 601 drives the first lead screw 602 to rotate. The first lead screw 602 drives the first rolling nut 604 and the first support 603 to move. The first support 603 drives the oil-gas separator 3 to move out of the cabinet 1. Similarly, the second transmission mechanism 7 drives the air compressor main unit 2 to move out of the side of the cabinet 1 for repair.
