Description

Technical Field

[0001] This invention relates to the field of air compressor technology, specifically to an energy-saving compressed air purification device. Background Technology

[0002] With industrial development, compressed air is widely used in modern industrial production and scientific experiments. Industries such as pharmaceuticals, chemicals, food, health products, precision instrument manufacturing, pneumatic instruments, and biochemical engineering all rely on sterile, high-purity compressed air. A gas compressor is a power device that converts mechanical energy into gas pressure energy. It often provides gas power for pneumatic tools and is also commonly used to compress gases such as oxygen and natural gas. Current gas compressors primarily compress gas through cylinders. To ensure smooth cylinder movement, lubricating oil is added between the piston and the cylinder. Due to the high temperature inside the cylinder, lubricating oil mixes into the compressed gas during compression. When using these compressed gases, oil-water separation is necessary. The separated gas then requires purification treatment to remove irrelevant impurities, depending on its intended use and function, to obtain the purest gas.

[0003] However, traditional compressed air purification systems are bulky, occupy a large area, have long pipelines, and are inconvenient to operate and maintain. When operators need to replace filter media, they must first stop the machine and then use mechanical tools to replace the new filter media, which consumes a lot of time and reduces the efficiency of the compressed air purification device. Moreover, the purification standards for gases used in different applications are different, and treating them with uniform purification may lead to energy waste. Therefore, they do not meet the current needs. To address this, we propose an energy-saving compressed air purification device. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving compressed air purification device to solve the problems mentioned in the background art. Traditional compressed air purification systems are characterized by large equipment size, long pipelines, and inconvenience in operation and maintenance. When operators replace filter media, they need to stop the machine and use mechanical tools to replace the new filter media, which consumes a lot of time and reduces the efficiency of the compressed air purification device. Furthermore, different purification standards are required for gases used in different applications, and uniform purification may lead to energy waste.

Furthermore, the first housing is connected to the base, the first housing is connected to the second housing, and the second housing is connected to the base. The second housing, the second housing and the third housing, and the third housing and the top seat can all be spliced ​​together by a splicing mechanism.

The pressure rod is symmetrically installed on both sides of the outer surface of the base, the first housing, the second housing, and the third housing through through holes, and a first spring is sleeved on the outer surface of the pressure rod.

[0008] Preferably, a storage groove is provided on the inner side of the through hole, and a locking block is fixedly connected to one end of the pressure rod. The end corner of the locking block near the strip-shaped insert is set as a second inclined surface. The locking block can be locked into the inner side of the slot, and the size of the locking block is smaller than the size of the storage groove.

[0009] Preferably, the sealing mechanism includes a fixing ring, the outer surface of which is fixedly connected to the inner wall of the insertion hole, two fixing plates are provided above the fixing ring, a second spring is fixedly installed on the lower end face of the fixing plate, a baffle is fixedly connected to the lower end face of the second spring, and a circular plate is installed on the lower end face of the baffle.

[0011] Preferably, a pull plate is installed on the rear end face of the sealing plate, and a vertical plate is installed on the front end face of the sealing plate. The vertical plate is connected to the oil-water adsorption device, the first filter device, the second filter device, the third filter device, and the drying device through slots. The sealing mechanism includes a sliding plate, which is disposed on both sides of the square groove through a sliding groove. The sliding plate is movably connected to the inner wall of the sliding groove through a third spring.

[0012] Preferably, a limiting plate is fixedly installed on one side of the opposite outer surface of the two slide plates, and a limiting groove is provided on both sides of the outer surface of the sealing plate. The square groove and the slide groove are connected through a connecting groove. The limiting plate passes through the connecting groove and can be inserted into the inner side of the limiting groove. A fourth spring is installed on both sides of the inner wall of the square groove.

[0013] Preferably, the oil-water adsorption device includes an absorber and a covering sleeve surrounding the absorber. The absorber is composed of a mixture of two or more of the following: natural fibers, chemical fibers, oil-absorbing polymers, and water-absorbing polymers.

After selecting the desired devices, they are assembled using the splicing mechanism. The strip-shaped insert is placed inside the strip-shaped groove. When the first and second inclined surfaces contact each other, the locking block is pressed inwards into the receiving groove. Once the strip-shaped insert is fully engaged, the pressure rod, under the action of the first spring, moves the locking block inwards into the slot, limiting its position. The splicing is then complete. Furthermore, a sealing mechanism automatically pushes the circular plate upwards after splicing, disengaging it from the inner side of the fixing ring. This creates an automatic airflow channel between the two devices, allowing gas to rise and be purified through the gap between the fixing ring and the circular plate. This invention allows for selective combination and can purify gases with different purification standards as needed, saving energy.

[0016] The present invention also includes a movable locking mechanism. When the unused device is idle, the sliding plates on both sides can be slid to move the limiting plate. The limiting plate moves away from the inner side of the limiting groove, releasing the limiting of the sealing plate. Under the action of the fourth spring, the sealing plate and the vertical plate are pushed outward of the square groove. The user can pull out the sealing plate, the vertical plate and the corresponding device by pulling the plate for cleaning. The present invention is easy to maintain and clean, and makes it convenient for operators to replace the filter material. Attached Figure Description
