Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and specifically, to an air compressor. Background Art

[0002] Some air compressors are installed in a closed or semi-closed environment in a factory building. In this case, if the humidity content of the air entering the air compressor is too high, a series of problems will occur. Because when the air humidity is high, moisture will enter the interior of the air compressor together with the air. These excess moisture will have an adverse effect on each component of the compressor, such as forming water vapor condensation on the surface of metal components.

[0003] During the operation of the compressor, these water vapors may cause the metal components to rust, and the rusted components will gradually erode the key parts of the compressor, greatly reducing its running smoothness. At the same time, excessive humidity may also erode some precision components inside the compressor, affecting their normal electrical and mechanical properties. These factors combined will cause the internal parts of the air compressor to wear more severely, the performance to gradually decline, and ultimately lead to a significant reduction in the lifespan of the air compressor.

[0023] The working principle and beneficial effects of the present utility model are as follows:

[0024] In the present utility model, in order to solve the problem that the air compressor installed in the factory building in the related art cannot automatically switch different air sources, an air compressor is designed. The main body of the device is a compressor core component made of a strong metal material, which has a first air inlet. The air inlet pipeline is composed of a plastic pipeline that is heat-resistant and corrosion-resistant. Among them, the second air inlet is arranged in the factory building.

[0025] Humidity detectors are respectively installed at the second air inlet and the third air inlet. For example, in a humid season, the humidity outside the factory building reaches 80%, while due to the ventilation and drying equipment inside the factory building, the humidity is only 60%. At this time, after the humidity detector outside the factory building detects the high humidity, it will send a signal to control an electric valve to close the third air inlet, thereby avoiding too much humid air from entering. And when some operations that may cause the humidity to rise are carried out inside the factory building, making the indoor humidity exceed the humidity outside the factory building, the indoor humidity detector will control to close the second air inlet and give priority to intake air from outside the factory building.

[0026] The advantages are that by respectively arranging humidity detectors at the air inlets inside and outside the factory building, the air compressor can automatically select a suitable air intake source according to the humidity conditions at different positions. This can effectively avoid humid air from entering the compressor and reduce the risk of rust and damage to the internal components of the compressor. In some production environments with high air quality requirements, this intelligent adjustment can ensure the stable quality of the compressed air. Selecting a suitable air intake source according to the humidity conditions helps to maintain a dry environment inside the compressor, reduce the erosion of moisture on the internal mechanical structure of the compressor (such as pistons, cylinders, etc.), thereby extending the service life of the compressor. At the same time, it also reduces the maintenance frequency of equipment failures caused by humidity problems and improves the reliability and stability of the entire production system.

In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0039] In this text, it should be noted that unless otherwise clearly stipulated and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0041] Refer to Figures 1 to 8 , which is the first embodiment of the present utility model, a kind of air compressor is proposed. It is installed inside the factory building and includes a device main body 1. The device main body 1 has a first air inlet 101; the air inlet pipeline 2 has a second air inlet 201, a third air inlet 202, and a first air outlet 203. The first air outlet 203 communicates with the first air inlet 101. The second air inlet 201 is located inside the factory building, and the third air inlet 202 is located outside the factory building; there are two humidity detectors 3, and the two humidity detectors 3 are respectively arranged at the second air inlet 201 and the third air inlet 202. The humidity detector 3 is used to detect the gas humidity of the second air inlet 201 and the third air inlet 202.

[0042] In this embodiment, in order to solve the problem that the air compressor installed inside the factory building in the related technology cannot automatically switch different air sources, a kind of air compressor is designed. The device main body 1 is a compressor core component made of a solid metal material, and it has a first air inlet 101. The air inlet pipeline 2 is composed of a plastic pipeline that is heat-resistant and corrosion-resistant. Among them, the second air inlet 201 is arranged inside the factory building. The third air inlet 202 is installed on the outer wall of the factory building. The first air outlet 203 is connected and communicated with the first air inlet 101 of the device main body 1 through a sealed connecting piece.

[0043] Humidity detectors 3 are respectively installed at the second air inlet 201 and the third air inlet 202. For example, in a humid season, the humidity outside the factory building reaches 80%, while the humidity inside the factory building is only 60% due to ventilation and drying equipment. At this time, after the humidity detector 3 outside the factory building detects high humidity, it will send a signal to control an electric valve to close the third air inlet 202, so as to avoid too much humid air from entering. And when some operations that may cause the humidity to increase are carried out inside the factory building, making the indoor humidity exceed the humidity outside the factory building, the indoor humidity detector 3 will control to close the second air inlet 201 and give priority to intake air from outside the factory building.

[0044] The advantage is that by respectively arranging humidity detectors 3 at the air inlets inside and outside the factory building, the air compressor can automatically select a suitable air inlet source according to the humidity conditions at different positions. This can effectively prevent humid air from entering the compressor and reduce the risk of rust and damage to the internal components of the compressor. In some production environments with high air quality requirements, this intelligent adjustment can ensure the stable quality of compressed air. Selecting a suitable air inlet source according to the humidity conditions helps maintain a dry environment inside the compressor, reduces the erosion of moisture on the internal mechanical structures of the compressor such as pistons and cylinders, thereby extending the service life of the compressor. At the same time, it also reduces the maintenance frequency of equipment failures caused by humidity problems and improves the reliability and stability of the entire production system.

[0045] Further, the air inlet pipeline 2 has a first pipeline 204 and a second pipeline 205. The first air outlet 203 is located at one end of the first pipeline 204, and the second air inlet 201 and the third air inlet 202 are located at one end of the second pipeline 205. A filtering device 4 is also included, and both ends of the filtering device 4 are respectively communicated with the first pipeline 204 and the second pipeline 205.

[0046] Further, both the other ends of the first pipeline 204 and the second pipeline 205 have first clamping grooves 2041. The filtering device 4 includes an installation cylinder 401, and both ends of the installation cylinder 401 have first insertion protrusions 4011. After the first insertion protrusions 4011 are abutted against the first clamping grooves 2041, the second air inlet 201 and the third air inlet 202 are communicated with the first air outlet 203; a filtering cylinder 402 is arranged inside the installation cylinder 401.

[0047] Further, the filtering cylinder 402 is rotatably arranged inside the installation cylinder 401. Both ends of the filtering cylinder 402 have limiting parts 4021. After the first insertion protrusions 4011 are abutted against the first clamping grooves 2041, rotate the filtering cylinder 402 so that the limiting parts 4021 are abutted against the inner wall of the air inlet pipeline 2 to fix the relative positions of the filtering device 4 and the air inlet pipeline 2.

[0048] Further, the installation cylinder 401 includes a first cylinder body 4012. One end of the first cylinder body 4012 has a first insertion protrusion 4011, and the other end has a sliding rod 4013; one end of the second cylinder body 4014 has another first insertion protrusion 4011, and the other end has a slide rail 4015. The sliding rod 4013 is slidably arranged inside the slide rail 4015. An installation space is formed between the first cylinder body 4012 and the first cylinder body 4012 for installing the filtering cylinder 402. After the sliding rod 4013 slides, the installation space expands or shrinks.

[0049] Further, the outer wall of the filter cartridge 402 has a first abutting portion 4022 and a second abutting portion 4023. After the first abutting portion 4022 abuts against one side of the slide rail 4015, the limiting portion 4021 and the first clamping groove 2041 coincide. After the filter cartridge 402 rotates, the second abutting portion 4023 abuts against the other side of the slide rail 4015, causing the limiting portion 4021 to abut against the inner wall of the air inlet pipeline 2.

[0050] Further, the two sides of the slide rail 4015 have second clamping grooves 4016. The filter device 4 further includes a pressing rod 403. There are two pressing rods 403, and the two pressing rods 403 are respectively rotatably arranged on the first abutting portion 4022 and the second abutting portion 4023. One end of the two pressing rods 403 close to the slide rail 4015 has a second insertion protrusion 4031. After the second insertion protrusion 4031 abuts against the second clamping groove 4016, the relative positions of the mounting cylinder 401 and the filter cartridge 402 are restricted; both ends of the elastic member 404 respectively abut against the filter cartridge 402 and one end of the pressing rod 403 away from the second insertion protrusion 4031, and are used to provide the force for the second insertion protrusion 4031 to abut against the second clamping groove 4016.

[0051] In this embodiment, the air inlet pipeline 2 is divided into a first pipeline 204 and a second pipeline 205, and both the first pipeline 204 and the second pipeline 205 have a first clamping groove 2041. The mounting cylinder 401 of the filter device 4 is made of high-strength engineering plastic, and the first insertion protrusions 4011 at both ends thereof are matched with the first clamping grooves 2041. During installation, the first insertion protrusions 4011 at both ends of the mounting cylinder 401 are inserted into the first clamping grooves 2041 to realize the communication between the second air inlet 201 and the third air inlet 202 and the first air outlet 203 through the filter device 4. One end of the first cylinder body 4012 of the mounting cylinder 401 has a first insertion protrusion 4011, and the sliding rod 4013 at the other end slides in the slide rail 4015 of the second cylinder body 4014. One end of the second cylinder body 4014 has a first insertion protrusion 4011, and the other end has a slide rail 4015. When it is necessary to replace a thicker filter cartridge 402, the sliding rod 4013 slides in the slide rail 4015 to expand the installation space between the first cylinder body 4012 and the second cylinder body 4014. The filter cartridge 402 is placed in the mounting cylinder 401, and it is composed of a coarse filter screen on the outer layer that can filter out larger dust particles, fibers, etc. and a fine filter screen on the inner layer that can filter out tiny dust, etc.

[0052] After the first insertion protrusion 4011 abuts against the first clamping groove 2041, the filter cartridge 402 can rotate within the installation cylinder 401. The limiting portions 4021 at both ends of the filter cartridge 402 abut against the inner wall of the intake pipeline 2 during the rotation process, thereby fixing the relative position of the filter device 4 and the intake pipeline 2. The first abutting portion 4022 on the outer wall of the filter cartridge 402 abuts against one side of the slide rail 4015 in the initial state, aligning the limiting portion 4021 with the first clamping groove 2041; after rotating the filter cartridge 402, the second abutting portion 4023 abuts against the other side of the slide rail 4015, causing the limiting portion 4021 to be in close contact with the inner wall of the intake pipeline 2. The second clamping grooves 4016 on both sides of the slide rail 4015 cooperate with the second insertion protrusions 4031 on the pressing rods 403. The two pressing rods 403 are respectively rotatably arranged on the first abutting portion 4022 and the second abutting portion 4023, and the elastic member 404, such as a small spring, is connected to the filter cartridge 402 and the pressing rod 403 at both ends, providing a force for the second insertion protrusion 4031 to abut against the second clamping groove 4016. After the second insertion protrusion 4031 and the second clamping groove 4016 abut, the filter cartridge 402 cannot rotate within the installation cylinder 401. When the other end of the pressing rod 403 is pressed, the second insertion protrusion 4031 and the second clamping groove 4016 are disengaged, and the filter cartridge 402 can rotate within the installation cylinder 401 again for installation or disassembly work.

[0053] The advantages are that the multi-layer filter screen structure in the filter device 4 can effectively remove impurities of different sizes. Whether it is large-particle dust or tiny bacteria, etc., they can all be intercepted, ensuring that the air entering the compressor is very pure, reducing the wear and damage of impurities to the internal components of the compressor, extending the service life of the compressor, and at the same time ensuring the cleanliness of the drug production environment. The cooperation between the first insertion protrusion 4011 and the first clamping groove 2041 makes the installation and disassembly of the filter device 4 simple and convenient. The adjustable design of the installation cylinder 401, the rotation and fixation method of the filter cartridge 402, and the cooperation between the pressing rod 403 and the elastic member 404 make the operation simple and fast when installing, replacing the filter cartridge 402 or performing equipment maintenance, without the need for professional personnel and complex tools, saving maintenance time and costs. The filter cartridge 402, through the abutment of the limiting portion 4021 against the inner wall of the intake pipeline 2 and the cooperation between the pressing rod 403 and the elastic member 404 with the second clamping grooves 4016 on both sides of the slide rail 4015, makes the entire filter device 4 have a stable structure during the working process, not easily affected by air flow impact and equipment vibration, ensuring the stable operation of the equipment and reducing the failure rate caused by unstable structure. The adjustable installation space of the installation cylinder 401 enables it to adapt to filter cartridges 402 of different thicknesses and specifications. Whether it is a new high-performance filter cartridge 402 or a traditional filter cartridge 402, it can be used in this equipment, improving the versatility of the equipment and meeting different filtration requirements.
