Description

Technical Field

[0001] This utility model relates to the field of air compressors, specifically a diaphragm pump compressed air booster device. Background Technology

[0002] Pneumatic diaphragm pumps are widely used in industries such as chemical, coating, environmental protection, pharmaceutical, and food due to their superior explosion-proof, safety, and self-priming characteristics. However, in actual use, many users overlook a crucial factor—the matching and stability of the air source, which directly affects the operating efficiency and service life of the equipment. Pneumatic diaphragm pumps typically require an air source pressure of 0.3MPa-0.7MPa (i.e., 3-7 kg pressure). Too low an air pressure may prevent the pump from starting, while too high a pressure may damage the diaphragm or pose a safety hazard.

[0003] For example, patent CN213511137U discloses an integrated air compressor with a tank, including a base plate and a compressor body. Wheels are installed at the four corners of the bottom surface of the base plate, and a vertical plate is installed on the upper surface of the base plate. An air tank is installed on one side of the vertical plate by a strap, and a shock-absorbing component is installed on the other side of the vertical plate. An installation plate is installed on the telescopic end of the shock-absorbing component, and a bearing plate is installed on the surface of the installation plate. A fixing strap is installed on the surface of the installation plate.

[0004] The aforementioned patent uses a vertical plate to fix the air tank and compressor body, facilitating overall movement of the device and eliminating the need for piping connections before each use, resulting in high space utilization. Simultaneously, the shock-absorbing components provide vibration protection during compressor operation, preventing significant vibrations between the vertical plate and the air tank, ensuring air compression, and making the device simple and convenient to use. However, the disadvantage of the aforementioned patent is that, in existing technologies, a large amount of moisture adheres to the inner wall of the air tank, which is difficult to remove; moisture separation is only performed on the compressed air discharged from the air tank during air output.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a diaphragm pump compressed air booster device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A diaphragm pump compressed air booster device includes a drive motor, a compressor, and an air storage tank. The drive motor drives and connects to the compressor, and the compressor's outlet is connected to the air inlet of the air storage tank via a pipeline. The air storage tank has an internal partition that divides it into a filter chamber and a storage chamber. A transition pipe is located slightly below the center of the partition to connect the filter chamber and the storage chamber. Several baffles are arranged alternately from top to bottom inside the filter chamber. A packing cylinder is connected to the top of the filter chamber, and a first perforated plate is fixedly installed at the bottom of the packing cylinder. Packing material is placed in the space above the first perforated plate, and a second perforated plate is installed above the packing material. A cover plate is fixedly fastened to the top of the packing cylinder via a connecting flange, and an exhaust pipe is connected to the center of the cover plate. A drain outlet is fixedly installed at the center of the bottom of the filter chamber.

[0009] Furthermore, the partition is arranged in an arc shape.

[0010] Furthermore, a manual drain valve is provided on the bottom right side of the gas storage chamber. The manual drain valve is used to control the opening and closing of the water outlet at the bottom of the gas storage chamber.

[0011] Furthermore, a liquid level sensor is installed at the top of the gas storage chamber, which is used to detect the liquid level of the condensate inside the gas storage chamber.

[0012] Furthermore, the surface of the baffle plate is roughened.

[0013] Furthermore, the sewage discharge port is connected to a triple gas-water separator.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The filter chamber is integrated inside the air storage tank. The device is separated by baffles, forming a fine filtration process of first baffle sedimentation and then packing adsorption. Compressed air passes through the baffles to agglomerate large particles and the packing for deep adsorption, achieving multi-stage high-efficiency purification from coarse to fine.

[0016] The packing cylinder features a flange cover structure for easy maintenance and long service life, facilitating packing replacement and maintenance. It is made of PTFE packing with excellent hydrophobic and oleophobic properties, which is corrosion resistant, has a long service life, and reduces long-term operating costs.

[0017] The gas storage chamber is equipped with a liquid level sensor to monitor water accumulation, and a manual drain valve and a triple gas-water separator at the bottom can effectively and automatically discharge the separated condensate and oil, ensuring stable system operation.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-5 The diaphragm pump compressed air booster device includes a drive motor 100, a compressor 200, and an air storage tank 300;

[0025] The drive motor 100 drives the compressor 200, and the air outlet of the compressor 200 is connected to the air inlet of the air storage tank 300 through a pipeline.

[0026] An arc-shaped partition 301 is provided inside the air storage tank 300, which divides the air storage tank 300 into a filter chamber 310 and an air storage chamber 320. A transition air pipe 302 is provided at the lower middle part of the partition 301 to connect the filter chamber 310 and the air storage chamber 320.

[0027] In this design, a manual drain valve 321 is provided on the bottom right side of the gas storage chamber 320; a liquid level sensor 322 is provided on the top of the gas storage chamber 320, which is used to detect the liquid level of the condensate inside the gas storage chamber 320; and the manual drain valve 321 is used to control the opening and closing of the water outlet at the bottom of the gas storage chamber 320.

[0028] The filter chamber 310 has several baffles 340 arranged alternately from top to bottom. The surface of the baffles 340 is rough so that the tiny water mist of the compressed air can be adsorbed on the surface of the baffles. The water droplets and oil droplets gather and grow larger before falling downwards.

[0029] The top of the filter chamber 310 is connected to a packing cylinder 330, and the bottom of the packing cylinder 330 is fixedly installed with a first perforated plate 331. Packing material 332 is placed in the space above the first perforated plate 330, and a second perforated plate 333 is installed above the packing material 332. A cover plate 335 is fixedly fastened to the top of the packing cylinder 330 via a connecting flange 334, and an exhaust pipe 336 is connected to the center of the cover plate 335. Simultaneously, a sewage discharge port 337 is fixedly installed at the center of the bottom of the filter chamber 310, and the sewage discharge port 337 is connected to a triple gas-water separator 338.

[0030] In use, compressed air containing water enters the filter chamber 310 from the air storage chamber 320 through the transition air pipe 302. Because the transition air pipe 302 is located at the bottom, the water vapor disperses and flows upwards, extending the water vapor flow path. During the upward flow of the water vapor, it first contacts the baffle plate 340. The baffle plate 340 is sandblasted, allowing the tiny water droplets from the compressed air to be adsorbed onto its surface. The water droplets and oil droplets gather and grow larger before falling downwards. The water vapor continues to flow upwards and encounters a hydrophobic barrier. The filler 332 (PTFE wire mesh demister) is made of a material with good oleophobic properties. PTFE is a commonly used material with good hydrophobic and oleophobic properties. It is a high molecular polymer composed entirely of carbon and fluorine. The reason why it can be both oleophobic and hydrophobic is that the fluorine ions in the molecule have extremely strong electronegativity, resulting in low polarity of the entire molecule and very small intermolecular forces. A triple gas-water separator is installed at the bottom of the tank, which can automatically and effectively discharge the oil and water in the pressure stabilizing tank. Finally, compressed air is discharged from the air outlet 3.
