Description

Technical Field

[0001] The utility model belongs to the technical field of air source filtering, and in particular relates to an air source filtering device with the function of separating water vapor. Background Art

[0002] In the machining industry, the quality of the air source directly impacts the machining accuracy and service life of the equipment. In traditional industries, to improve air quality, gas drying and filtration equipment are connected to the front end of the air source. However, when the air source has a high flow rate and contains a lot of water vapor or impurities, the air source cannot be completely purified and does not meet the standards for processing air. Particulate matter, water vapor, and oil mist mixed in the gas can damage the parts of the gas-using equipment and rust the products. Frequent replacement of filter elements in the filtration equipment is also necessary. However, frequent replacement of air source filter elements wastes production time and interrupts equipment production, making it impossible to meet the current high-precision and high-efficiency production requirements. Utility Model Content

[0003] The utility model provides an air source filter device with a water vapor separation function, which is installed at the front end of the air source inlet of the gas-using equipment. Through the air path collision bionic structure, the main air path filter, the stainless steel filter bottle filter, and the three-layer step-by-step filtering structure, it purifies the particulate matter, water vapor, and oil mist in the air source, improves the air source quality of the equipment terminal, reduces the equipment maintenance frequency, improves the equipment production efficiency, and thus increases the stability and reliability of the equipment.

[0004] The technical solution of the utility model is:

[0005] An air source filtration device with a water vapor separation function is characterized in that it includes an air source filtration structure and a foreign matter collection structure; the air source filtration structure includes three levels of air source filtration, namely an air path collision bionic structure, a main air path filter, and a stainless steel filter bottle, which are connected to each other through an air path pipeline; the foreign matter collection structure includes an automatic drain valve and a foreign matter collection bottle, which are connected to the air source inlet tee, a second 90° reducing elbow, and a foreign matter outlet tee through an air path pipeline.

[0006] Furthermore, the gas path collision bionic structure is installed vertically, and three interlaced baffle structures are welded inside, occupying two-thirds of the inner diameter of the pipeline. The baffle structure is semicircular.

[0007] Furthermore, the lower surface of the baffle structure is uneven, which increases the surface roughness and reduces the contact elasticity of particles.

[0008] Furthermore, the upper outlet of the gas path collision bionic structure is connected to the gas path pipeline through a first 90° reducing elbow; the lower end of the gas source inlet tee is connected to the gas path pipeline through a second 90° reducing elbow.

[0009] Furthermore, the discharge port of the main air filter is connected to the inlet of the foreign matter discharge tee through an air pipeline, so that the oil, water and particulate impurities discharged from the main air filter and the automatic drain valve can be collected into a foreign matter collection bottle.

[0010] Furthermore, the automatic drain valve can adjust the drainage frequency by itself through an external threaded knob structure, and regularly discharge the oil, water, and particulate impurities stored in the automatic drain valve.

[0011] Furthermore, the components included in the air source filtering structure and the foreign matter collecting structure are encapsulated inside and outside the device housing through a fixing frame.

[0012] Furthermore, a muffler is installed at the mouth of the foreign matter collection bottle.

[0013] Furthermore, the foreign matter collecting bottle can be disassembled and cleaned.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] An air source filter device with a water vapor separation function comprises an air source filter structure and a foreign matter collection structure; wherein the air source filter structure is provided with three levels of air source filtration, and the filtration accuracy increases step by step.

[0016] Specifically, the first-stage filtration is an air path collision bionic structure, which mainly filters clear water and large particulate impurities in the air source; the second-stage filtration is a main air path filter, which further filters escaped water vapor, oil mist and small particulate impurities; the third-stage filtration is a stainless steel filter bottle for final fine filtration.

[0017] Furthermore, the water vapor and particulate impurities separated by the main gas path filter can be collected through the pipeline, thereby increasing the service life of the main gas path filter.

[0018] Furthermore, the automatic drain valve can set the foreign matter discharge time by itself and discharge the foreign matter regularly.

[0019] Furthermore, a muffler is installed at the mouth of the foreign matter collection bottle connected to the outside of the device shell, which can reduce the sound made by the device when foreign matter is discharged.

[0020] In summary, this utility model solves the problems of traditional air filtration equipment, such as incomplete purification, the need for frequent filter element replacement, resulting in low product precision and discontinuous production. It improves the gas quality at the equipment terminal, reduces equipment maintenance frequency, improves processing accuracy and production efficiency, and thus increases equipment stability and reliability.

[0024] It should be noted that the terms "install," "connect," and "fix" should be understood broadly in the present description. For example, "connection" can include direct, integrated connections, detachable connections, fixed connections, or indirect connections through other media. Unless otherwise specified, no specific restrictions or limitations are imposed, provided that normal air flow between the various structures is ensured and foreign matter can be properly discharged.

[0025] See Figure 1 The gas source inlet is connected to the gas source inlet tee 1, the upper outlet of the gas source inlet tee 1 is connected to the gas path collision bionic structure 2 pipeline, the upper outlet of the gas path collision bionic structure 2 pipeline is connected to the gas path pipeline 4 through the first 90° reducing elbow 3, the right side of the gas path pipeline 4 is connected to the air inlet of the main gas path filter 5, the air outlet of the main gas path filter is connected to the air inlet of the stainless steel filter bottle 6 through the gas path pipeline 4 of the same diameter, and the air outlet of the stainless steel filter bottle 6 is connected to the gas source outlet outside the device housing 10.

[0026] See Figure 1 The gas source inlet is connected to the gas source inlet tee 1, the lower outlet of the gas source inlet tee 1 is connected to the second 90° reducing elbow 11, the lower outlet of the second 90° reducing elbow 11 is connected to the inlet of the automatic drain valve 9 through a drainage pipe, the outlet of the automatic drain valve 9 is connected to the port b of the foreign matter discharge outlet tee 8, the port a of the foreign matter discharge outlet tee 8 is connected to the discharge outlet of the main gas path filter 5 through an gas path pipe, and the port c of the foreign matter discharge outlet tee 8 is directly connected to the foreign matter collection bottle 11 outside the device housing 10 through a tube.

[0027] See Figure 2 The gas path collision bionic structure 2 is installed vertically, and three baffle structures 12 are welded inside, which are staggered and occupy two-thirds of the inner diameter of the pipeline. The baffle structure 12 is semicircular, and the distance between the baffle structures 12 is 60 cm. An uneven surface is set under the baffle structure 12 to increase the surface roughness and reduce the contact elasticity of the particles.

[0028] The technical principle and usage of this utility model are:

[0029] The utility model adopts the design principle of inertial collision, gravity sedimentation and fiber interception.

[0030] The compressed airflow containing particulate matter, water, and oil enters the air source inlet and travels upward through the air path, impacting bionic structure 2. When the airflow encounters a barrier structure 12 within bionic structure 2, the air is deflected around the obstacle. However, the water, oil, and particulate matter in the air continue to move in their original direction due to inertia, thus separating from the airflow. Once separated from the airflow, the water, oil, and particulate matter settle along the inner wall of the pipe due to gravity, enter automatic drain valve 9, and are then discharged into foreign matter collection bottle 7.

[0031] There is still a small amount of water, oil mist and small particle impurities in the air flow after being filtered by the air path collision bionic structure 2. This air flow flows into the main air path filter 5 to complete the secondary filtration. The main air path filter 5 has higher precision and can separate the trace water vapor, oil mist and particulate matter escaping from the air path collision bionic structure. The air flow coming out of the main air path filter 5 finally flows into the stainless steel filter bottle 6 and completes the third level filtration through the fiber interception principle, and the dry and pure gas is discharged through the air source outlet and connected to the use equipment.

[0032] The exhaust port below the main air path filter 5 of the air source filtering structure is connected to the outlet pipe of the automatic drain valve 9 of the foreign matter collection structure through the air path pipeline, and the water, oil and impurities separated by the main air path filter 5 are also discharged into the foreign matter collection bottle 7.

[0033] The filter elements of the main gas line filter 5 and the stainless steel filter bottle 6 need to be replaced regularly.
