Description

Technical Field

[0001] The invention belongs to the field of nitrogen compression equipment, and in particular relates to a nitrogen compressor with an oil pollution prevention function. Background Art

[0002] Nitrogen is a colorless, odorless gas that can be compressed to high pressure. It is insoluble in water and ethanol, has an inactive chemical property, and is difficult to react with other substances at room temperature. Nitrogen accounts for 78.08% of the total atmosphere and is the main component of air. It is easy to obtain and has low cost. Nitrogen has a wide range of uses. For example, in food, medicine, animal husbandry, refrigeration, electronics industry, metal smelting, chemical industry, mechanical processing, synthetic fertilizers, oil field mining and other industries, nitrogen is needed and the demand is huge. Nitrogen compression is the process of reducing the volume of nitrogen and increasing the frequency and energy of intermolecular collisions. During the compression process, the nitrogen molecules will become tighter. The frequency of collisions between them increases, which leads to an increase in the average kinetic energy of nitrogen molecules and an increase in temperature. Therefore, in the process of nitrogen compression, it is necessary to achieve the goal of reducing pressure and temperature at the same time to ensure the stability and safety of nitrogen. Although compressed nitrogen consumes energy and equipment, in many applications, compressed nitrogen can provide a more economical and efficient solution. For example, in the medical field, the use of compressed nitrogen instead of liquid nitrogen can reduce storage and transportation costs, which requires the use of nitrogen compressors. Nitrogen compressors are widely used in many industrial fields, such as chemical, petroleum, electronics, and medicine.

[0003] Chinese patent CN218441303U discloses a nitrogen compressor, including a compressor body installed on a base, accommodating grooves are symmetrically provided on both sides of the lower surface of the base, a lifting block is slidably connected in the accommodating groove, and a moving wheel is fixedly connected to the lifting block; a horizontally arranged screw rod is rotatably connected to the lower surface of the base, a pair of threaded blocks are threadedly connected on the screw rod, the threaded block is rotatably connected to the lifting block through a support rod, and the screw rod is provided with thread lines in opposite directions, and the two threaded blocks are respectively threadedly connected to different thread lines of the screw rod; a conversion piece is fixedly connected to the base, and a first bevel gear and a second bevel gear that mesh with each other are rotatably connected to the conversion piece, and the screw rod passes through and is fixedly connected to the second bevel gear.

[0004] When the above equipment is in use, before the nitrogen enters the compressor, a certain amount of oil will accumulate inside the nitrogen generator during long-term use. If the cleaning and maintenance of the equipment are not in place, these oils will be discharged along with the nitrogen, resulting in oil stains in the nitrogen. When the nitrogen is compressed, the oil will remain inside the compressor. The oil accumulates inside the compressor to form sludge or mix with other impurities, and adhere to the inner wall, pipes and components of the equipment, which will block the pipes, reduce the nitrogen circulation efficiency, and cause wear and even damage to the precision parts inside the compressor.

[0016] The present invention has the following beneficial effects: 1. In the present invention, through the cooperation between the filter screen and the filter tube, after the nitrogen containing oil stains enters the interior of the filter tube through the intake pipe, since the end of the filter screen cylinder close to the intake pipe is connected, and the other end of the filter screen cylinder is provided with a separation plate, when the nitrogen enters the interior of the filter tube through the intake pipe, the nitrogen containing oil stains is then filtered out of the oil stains through the interior of the filter screen cylinder, and the filtered nitrogen is transported to the interior of the filter tube through the filter screen cylinder, and then transported to the interior of the nitrogen compressor body through the exhaust pipe, thereby completing the filtration of the nitrogen containing oil stains before compressing the nitrogen. By filtering out the oil stains in the nitrogen through the filter screen, the purity of the nitrogen can be significantly improved. The oil stains cause damage to certain sensitive equipment and materials, such as corrosion, pollution or performance degradation. Filtering the oil stains from the nitrogen before compressing it can protect these equipment and materials and ensure their normal operation and long-term stability.

[0017] 2. In the present invention, through the mutual cooperation between the bidirectional screw rod, the sliding plate, the driving block, the spray sleeve and the cleaning sleeve, the bidirectional screw rod rotates to make the bottom end of the sliding plate slide on the surface of the bidirectional screw rod, thereby making the sliding block slide on the surface of the guide rod. Since the sliding plate is fixedly connected to the driving block, when the bottom end of the sliding plate is slidably set on the surface of the bidirectional screw rod to slide, the end of the driving block close to the spray sleeve slides inside the first slideway, and the driving block moves to make the spray sleeve move, and at the same time makes the cleaning sleeve move accordingly. While moving, the spray sleeve sprays the cleaning agent for neutralizing the oil stains on the surface of the filter screen. After spraying the cleaning agent, the surface of the filter screen is scraped off by the cleaning sleeve. The sprayed cleaning agent can directly act on the oil stains on the surface of the filter screen, effectively neutralize and decompose the oil stains, making them easier to remove. The subsequent brushing action can further mix the cleaning agent with the oil stains to ensure that the oil stains are thoroughly removed. The long-term accumulation of oil stains and other dirt may damage the filter screen and shorten its service life. By spraying cleaning agent in time and brushing cleaning, these dirt can be effectively removed, protecting the filter and extending its service life.

[0018] 3. In the present invention, through the mutual cooperation between the elastic scraper, the movable blocking plate and the absorption component, the elastic scraper slides on the inner bottom end of the filter tube, so that the oil stains and dirt dropped on the inner bottom end of the filter tube are moved, and when the spray sleeve drives the elastic scraper to move to one end of the movable blocking plate, the elastic scraper makes the two ends of the movable blocking plate slide on the second slide, and the movable blocking plate slides to the upper surface of the fixed plate. At this time, the oil stains and dirt fall into the interior of the collecting shell, and then the absorption component is started, so that the oil stains and dirt inside the collecting shell enter the interior of the absorption component through the collecting pipe. The oil stains cleaned by the filter are transported into the nitrogen compressor through the exhaust pipe, which may block the pipeline and damage equipment components, thereby affecting the performance and life of the compressor. Collecting and removing these oil stains can ensure the normal operation of the nitrogen compressor and maintain its performance.

[0019] 4. In the present invention, the driven rod rotates through the mutual cooperation between the driven rod, the rotating hollow rod and the drain pipe, and the rotation of the driven rod causes the rotating hollow rod to rotate, so that the drain pipe is straightened following the movement of the spray sleeve. When the spray sleeve is reset, the driving shaft of the motor is reversed, thereby causing the driven rod to reverse. At this time, the rotating hollow rod is reversed. Since one end of the drain pipe is fixedly connected to the water inlet, when the rotating hollow rod is reversed, the drain pipe is rolled up on the circumferential wall of the rotating hollow rod, thereby preventing the drain pipe from becoming tangled when the spray sleeve reciprocates and sprays the cleaning agent on the surface of the filter. The tangled drain pipe will hinder the water flow and cause poor drainage. In severe cases, it may cause water overflow or backflow, causing damage to the equipment and the surrounding environment. The tangled drain pipe will prolong the cleaning time and increase the difficulty of cleaning. Therefore, preventing the drain pipe from becoming tangled can improve the cleaning efficiency of the spray sleeve.

The elastic scraper 401 is installed on the bottom surface of the spray sleeve 308, and the sewage discharge assembly is arranged at one end of the filter tube 201.
