Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and particularly to a highly efficient shock-absorbing box-mounted screw air compressor. Background Art

[0002] In many fields such as industrial production, construction, and mining, air compressors, as power equipment for providing compressed air, play a crucial role. Among them, screw air compressors have become a relatively widely used type of air compressor in the market due to their advantages such as compact structure, stable operation, and high gas production efficiency; screw air compressors are divided into oil-lubricated screw air compressors and dry screw air compressors. Oil-lubricated screw air compressors: Inject oil into the compression chamber to cool and lubricate the main compressor unit, and at the same time help take away the heat generated during the compression process and minimize air leakage as much as possible. They are suitable for applications where the equipment is required to operate continuously, with low oil carry-over, and low long-term loss of exhaust volume, and are widely used in various industrial fields.

[0003] During the operation of traditional oil-lubricated screw air compressors, the problem of improper lubricating oil treatment has always been a key factor restricting the improvement of equipment performance and stable operation. After participating in the operation of the compressor, the lubricating oil will carry a large amount of heat. If it cannot be cooled in a timely and effective manner, the equipment is prone to overheating, resulting in problems such as carbon deposition and coking, shortening the service life of the equipment. If not processed in time, impurities will enter the internal part of the screw machine main unit along with the lubricating oil, further aggravating the wear of components such as screws and bearings, leading to unstable operation of the equipment, and even causing serious failures such as the main unit being stuck, affecting the normal progress of production. Summary of the Invention

[0016] Working principle: When the equipment is officially started, the screw machine motor starts to operate, driving the first pulley to rotate. Then, through belt transmission, the second pulley rotates, and finally drives the male and female rotors in the screw machine main unit to rotate. At this time, the intake valve assembly automatically adjusts the opening according to the initial pressure of the compressor and is ready to inhale air. The air filter simultaneously filters the inhaled air preliminarily to remove impurities such as dust and particles carried therein. As the screw machine main unit operates, gas is inhaled from the intake valve assembly into the compression chamber. During the compression process, lubricating oil is sprayed into the compression chamber to improve the compression efficiency. The gas and the lubricating oil are mixed to form an oil-gas mixture, which is introduced into the oil-gas separation tank. The oil-gas separation tank realizes the preliminary oil-gas separation, reducing the load on the subsequent filter element. Then, the oil-gas mixture enters the oil-gas separation core, which finely separates the mixture and reduces the lubricating oil content in the compressed air to an extremely low level, thus ensuring that the output air quality meets the requirements. The lubricating oil after oil-gas separation enters the cooler. The fan assembly is located below the air inlet filter plate and provides forced ventilation for the cooler, enabling the lubricating oil to dissipate heat quickly. The temperature control valve monitors the temperature of the lubricating oil in real time and automatically adjusts the oil circuit according to the preset set value. The lubricating oil after heat dissipation then passes through the oil filter, which filters out impurities in the lubricating oil. The filtered clean lubricating oil returns to the inside of the screw machine main unit, forming a complete lubricating oil circulation compressor, which plays a protective role for the screw main unit and the bearings. After the compressed air is separated from oil and gas, it passes through the minimum pressure valve. Subsequently, the compressed air enters the refrigerated dryer, which reduces the temperature of the compressed air through refrigeration technology, causing the water vapor in the air to condense into liquid water and be discharged. The compressed air processed by the refrigerated dryer then enters the precision filter, which further filters out the oil mist, moisture, and fine particles in the compressed air, further improving the quality of the compressed air. The compressed air after precision filtration is introduced into the interior of the air storage tank through the control of the ball valve. The air storage tank is arranged inside the casing, and its main function is to store compressed air, stabilize air pressure fluctuations, reduce the start-stop frequency of the compressor, and reduce the energy consumption and wear of the equipment. When cleaning the inlet air filter plate and the exhaust air filter plate, first start the motor 1 installed on the bracket near the inlet air filter plate and the exhaust air filter plate to drive the reciprocating lead screw to rotate, drive the slider to slide, the slider drives the sleeve 1 to slide, and then drives the rotating shaft 1 to slide, so that the scraper scrapes the debris on the outer wall of the filter plate for cleaning; then start the motor 2 fixed on the mounting bracket of the cross bar 2 to drive the worm to rotate, make the worm gear rotate, and then drive the outermost rotating shaft 1 to rotate. When this rotating shaft 1 rotates, through the sleeve 3 and the cross bar 3 rotatably connected to its outer wall, all scrapers are synchronously rotated, thereby improving the cleaning effect, and tilting the scraper when the scraper does not slide, reducing noise while ensuring ventilation.

[0017] The present invention provides a high-efficiency shock-absorbing box-mounted screw air compressor. It has the following beneficial effects: 1. Through the dual separation mechanism of the oil-gas separation tank and the oil-gas separation core, this compressor can finely filter the lubricating oil in the compressed air, greatly reducing the oil content in the exhaust gas, ensuring the high quality of the output air. At the same time, the separated lubricating oil is recycled after cooling and filtration, which not only protects the main engine components but also reduces the lubricating oil consumption and replacement cost.

[0018] 2. The present invention is equipped with a perfect filtration and drainage system. The inlet air filter plate and the exhaust air filter plate can effectively filter the air entering the interior of the casing, prevent debris from entering, and ensure the heat dissipation efficiency; the air filter further filters the dust and particulate impurities in the inhaled air to prevent foreign objects from entering the main engine and wearing the screw and internal parts. In addition, the precision filter can further filter the oil mist, moisture, and fine particles in the compressed air. The drain valve and the electric valve can automatically discharge the filtered moisture and the condensate water at the bottom of the air storage tank. This design ensures the cleanliness of the air through multi-stage filtration, and at the same time, the automatic drainage system reduces the manual maintenance workload, improves the automation degree and operation stability of the equipment.

[0019] 3. The present invention integrates multiple components of a screw air compressor, including a screw compressor main unit, an intake valve assembly, an oil-gas separation tank, a cooler, an oil filter, a fan assembly, an air filter, a minimum pressure valve, a refrigerant dryer, a precision filter, an air storage tank, a drain valve, an electric valve, a pressure gauge, a safety valve, a rocker switch, and a central control cabinet, etc., all within a casing. This integrated design makes the entire device structure compact, occupies a small area, is convenient for installation and transportation, reduces external pipeline connections at the same time, and lowers the leakage risk and installation cost.

[0020] 4. The present invention drives the sliding of a sleeve one, a rotating shaft one, and a scraper by arranging components such as a motor one, a reciprocating lead screw, a slider, and a slide bar at the top and side of the casing, which can automatically scrape off the sundries on the outer walls of the air inlet filter plate and the air exhaust filter plate, realizing the automatic cleaning of the filter plates, and ensuring the normal operation of the ventilation compressor inside the casing at the same time; further, a motor two, a worm, a worm gear, and a synchronization mechanism are provided. The motor two drives the worm and the worm gear to rotate, so that all the scrapers rotate synchronously. After the scrapers rotate synchronously, they can change the angle, improving the cleaning effect; the scrapers can adjust the opening angle in a timely manner according to the change of temperature, ensuring that the screw air compressor works at a constant temperature within the best temperature range.

[0024] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, an embodiment of the present invention provides an efficient shock-absorbing box-mounted screw air compressor, including a housing 1. A partition board 11 is installed inside the housing 1. A screw compressor main unit 2 is fixedly arranged inside the housing 1. An intake valve assembly 3 is fixedly connected to the input end of the screw compressor main unit 2. An oil-gas separation tank 4 is arranged on the upper surface of the partition board 11. The oil-gas separation tank 4 is connected to the intake valve assembly 3 through a pipeline. The oil-gas separation tank 4 is connected with an oil-gas separation core 5. The oil-gas separation core 5 is connected to a cooler 6 through a pipeline. The cooler 6 is fixedly connected to the upper side inside the housing 1. The cooler 6 is connected to a temperature control valve 7 through a pipeline. The outer wall of the temperature control valve 7 is fixedly connected with an oil filter 8. Both the temperature control valve 7 and the oil filter 8 are installed inside the housing 1. The oil filter 8 is connected to the oil-gas separation tank 4 and the screw compressor main unit 2 through pipelines. A driving mechanism is arranged on the upper surface of the partition board 11. The driving mechanism is connected to the ball valve 22.

[0026] Specifically, the casing 1 fixes the partition 11, and the main unit 2 of the screw compressor is fixed inside the casing 1. There are two meshing screws in the compression chamber of the main unit 2 of the screw compressor, namely the main screw and the slave screw. When the screws rotate, gas is inhaled from the suction end into the compression chamber, and oil is injected into the compression chamber to cool and lubricate the main unit of the compressor, while helping to carry away the heat generated during the compression process and minimizing air leakage as much as possible. The intake valve assembly 3 controls the air flow into the compressor and automatically adjusts the opening degree according to the compressor pressure, such as in the loading / unloading state, to achieve energy-saving operation. The compressor introduces the mixed gas into the oil-gas separation tank 4. The oil-gas separation tank 4 preliminarily separates the lubricating oil in the compressed air, and the oil droplets settle through centrifugal force and gravity to reduce the load on the subsequent filter element. Subsequently, the oil-gas separation element 5 is used for fine separation of the lubricating oil in the compressed air to reduce the oil content in the exhaust gas to an extremely low level and ensure the output air quality. The separated lubricating oil enters the cooler 6 to prevent the equipment from overheating. The temperature control valve 7 automatically adjusts the oil circuit according to the lubricating oil temperature. When the oil temperature is lower than the set value, the oil directly circulates, and when it is higher than the set value, the oil is guided through the cooler 6 for heat dissipation to maintain the oil temperature stable. Finally, the oil filter 8 filters impurities such as metal debris and carbon deposits in the lubricating oil, returns to the inside of the main unit 2 of the screw compressor, forms a cycle, protects the main screw of the screw compressor and the bearings, and extends the service life of the equipment.

The display screen 19 facilitates the operator to perform interactive operations on the refrigerated dryer 18.
