[0001] This invention relates to the field of oil fume purification technology, and in particular to a gas-liquid-solid separation purifier for oil fumes. Background Technology

[0002] Restaurants, hotels, and other catering businesses, as well as households, generate a large amount of oily fumes during the cooking and processing of food. In addition to water vapor, oil mist, and fine particulate matter, oily fumes also contain volatile substances and odorous gases. After the oil is removed by the range hood, the oily fumes need to be filtered out by a separator to remove the moisture and particles from the oily fumes. Existing technologies typically use filtration to remove dust from oily fumes, separating the gas and solids for purification. However, they cannot separate the gas, liquid, and solid components, leading to inconsistencies in operation. Therefore, there is an urgent need for a gas-liquid-solid separation purifier for oily fumes. Summary of the Invention

The filter cylinder rotates slowly, causing the rubber frame to rub against the inner wall of the filter cylinder, scraping off the dust on the inner wall of the filter cylinder. This can quickly clean the dust on the inner wall of the filter cylinder, ensuring the filtration efficiency of the filter cylinder for oily fumes and exhaust gases, and has the advantage of high filtration efficiency. The dehumidifier cylinder rotates slowly, constantly being blown over by the oily fumes. The cylinder continuously absorbs moisture from the fumes, and then the hot airflow carries away the moisture. The dehumidifier cylinder continuously transfers moisture from the oily fumes to the hot airflow, quickly removing moisture from the fumes and achieving gas-liquid-solid separation. It has the advantages of high dehumidification efficiency and great ease of use. Attached Figure Description

[0025] The diverter 42 is fixedly installed at its end on the inner wall of the vertical pipe 4. The end of the diverter 42 is inserted into the air inlet 41, allowing air to flow through the heating rod 43. The air is fully heated by the heating rod 43, and a hot airflow is quickly formed inside the air inlet 41. The heating rod 43 is fixedly installed at its end through the middle of the air inlet 41. The filter plate 45 is fixedly installed on the inner wall of the air inlet 41. The filter plate 45 filters the air and prevents impurities from being sucked into the air inlet 41. The drive unit 44 is fixedly installed on the inner wall of the air inlet 41 by a support rod. The drive unit 44 is a high-speed motor that can be purchased from the market or custom-made. The fan blade 46 is fixedly installed on the power output end of the drive unit 44.

[0026] In this invention, the bottom of the fixed box 1 is provided with a folding end 11, which folds the bottom of the fixed box 1 together and can store dust. The bottom of the folding end 11 is detachably fitted with a protective cover 12, which blocks the bottom of the folding end 11. A pin frame 13 is movably passed through the middle of the protective cover 12 and passes through the bottom of the folding end 11, so that the protective cover 12 can be detachably installed on the bottom of the folding end 11. A sliding frame 14 is fixedly provided on the front of the fixed box 1, and a limit plate 16 is movably passed through the front of the fixed box 1.

[0027] In this invention, at least two pin rods 15 are movably passed through the side of the sliding frame 14. The end of the limiting plate 16 is provided with a lifting frame 17 that can move up and down. The inner side of the lifting frame 17 is parallel to the side of the limiting plate 16. The lifting frame 17 can move up and down on the side of the limiting plate 16. A counterweight plate 18 is fixedly provided at the bottom of the lifting frame 17. The gravity of the counterweight plate 18 acts on the top of the rubber frame 19, so that the bottom of the rubber frame 19 abuts against the inner wall of the filter cylinder 24, scraping off the dust on the inner wall of the filter cylinder 24. The bottom of the counterweight plate 18 is embedded in the rubber frame 19.

[0028] In this invention, a dehumidification pipe 110 is provided on the side of the fixed box 1, and the dehumidification pipe 110 is connected to the interior of the fixed box 1. A power component 111 is fixed on the front of the fixed box 1 by a support rod. A small gear 113 is nested and fixed on the power output end of the power component 111. The power output end of the power component 111 is rotatably passed through the back of the fixed box 1 by a support component 112. The support component 112 is a cylindrical roller bearing, which can be obtained by purchasing from the market or by private customization. The power component 111 is a progressive motor, which can be obtained by purchasing from the market or by private customization. A partition plate 114 is fixedly provided in the middle of the inner wall of the fixed box 1.

[0029] In this invention, the pinion 113 is located between the upper gear 311 and the lower gear 23. The top and bottom of the pinion 113 are engaged with the upper gear 311 and the lower gear 23, respectively. The top of the elbow tube 210 is respectively inserted through the intermediate plate 31 and the center plate 310. The rotation of the pinion 113 can drive the upper gear 311 and the lower gear 23 to rotate. The diameters of the upper gear 311 and the lower gear 23 are consistent. The diameter of the pinion 113 is smaller than the diameter of the upper gear 311. The linear velocities of the pinion 113 and the upper gear 311 when rotating are consistent, which can greatly reduce the angular velocity of the upper gear 311 when rotating.

[0030] In this invention, the two ends of the horizontal frame 35 are respectively connected to the two discharge boxes 36. The discharge boxes 36 can collect the dehumidified oil fume exhaust gas and discharge it through the discharge pipe 38. The two ends of the middle frame 27 are respectively connected to the two discharge frames 25. The discharge frames 25 can collect the filtered oil fume exhaust gas and discharge it through the middle frame 27. The angle between the top end of the elbow pipe 210 and the side of the fixed box 1 is 40°-50°. The top ends of the two elbow pipes 210 are kept parallel and staggered to prevent the oil fume exhaust gas discharged from the top of the two elbow pipes 210 from colliding, so that the oil fume exhaust gas flows quickly inside the horizontal frame 35. The dehumidification pipe 110 is located above the middle partition 114, and the interior of the vertical pipe 4 and the interior of the dehumidification cylinder 33 are interconnected.

[0031] In this invention, the dehumidifier cylinder 33 has an opening with a through hole, which can increase the speed at which the oily exhaust gas passes through the dehumidifier cylinder 33, enabling the oily exhaust gas to quickly complete the dehumidification work. The dehumidifier cylinder 33 uses silicate desiccant adsorption. The dehumidifier cylinder 33 can be made of aluminum substrate, or it can be made of inorganic fiber substrate, which can provide maximum sensible heat recovery. The dehumidifier cylinder 33 is made of alternating flat and corrugated aluminum foil with uniform width. The rotating honeycomb aluminum foil forms a rigid medium with very good structural strength through winding and attachment, which will not crack or deform due to changes in temperature or humidity.

[0032] In this invention, the pin rod 15 passes through the sliding frame 14 and the limiting plate 16, fixing the limiting plate 16 in the sliding frame 14. The limiting plate 16 passes through the front of the fixed box 1, so that the limiting plate 16 is located in the lifting frame 17. The lifting frame 17 can slide on the side of the limiting plate 16, so that the lifting frame 17 moves horizontally up and down, so that the rubber frame 19 abuts against the inner wall of the filter cylinder 24. The rubber frame 19 can rub against the inner wall of the filter cylinder 24, scraping off the dust on the inner wall of the filter cylinder 24, completing the cleaning work of the inner wall of the filter cylinder 24. The dust falls through the notch of the driven coil 29 and falls onto the retractable end 11 at the bottom of the fixed box 1.

[0033] In this invention, firstly, the oily fume exhaust gas is connected to the inlet pipe 28. The oily fume exhaust gas is then transported through the inlet pipe 28 to the interior of the intermediate frame 27. The oily fume exhaust gas is discharged through both ends of the intermediate frame 27. After passing through the filter cylinder 24, the oily fume exhaust gas is filtered, and the filter cylinder 24 filters out the particulate dust in the oily fume exhaust gas. The dust accumulates on the inner wall of the filter cylinder 24, completing the separation of gas and solid. The filtered oily fume exhaust gas enters the interior of the two discharge frames 25. The filtered oily fume exhaust gas is then transported through the elbow pipe 210 into the interior of the transverse frame 35. The oily fume exhaust gas is discharged through both ends of the transverse frame 35. The oily fume exhaust gas passes through the dehumidification cylinder 33, where its moisture is absorbed. The dehumidifier 33 absorbs moisture from the oily exhaust gas, removing the moisture and completing the gas-liquid separation. The power component 111 drives the pinion 113 to rotate, which in turn drives the lower gear 23 and the upper gear 311 to rotate. This causes the lower gear 23, driven plate 22, filter cylinder 24, and driven ring 29 to rotate slowly, and the upper gear 311, sealing ring 32, dehumidifier 33, and driven ring plate 34 to rotate slowly. The drive component 44 drives the fan blades 46 to rotate at high speed. The rotation of the fan blades 46 creates airflow inside the air inlet duct 41. The filter plate 45 filters the air to prevent impurities from entering the air inlet duct 41. The heating rod 43 spirally wraps around the gap between the diverter 42 and the air inlet duct 41. The heating rod 43 heats the airflow inside the air inlet duct 41 to form a hot airflow. The hot airflow is transported into the dehumidification cylinder 33 through the vertical pipe 4. The hot airflow passes through the dehumidification cylinder 33 and heats it, causing the moisture absorbed by the dehumidification cylinder 33 to form water vapor. The water vapor follows the flow of the hot airflow. The hot airflow and water vapor are then discharged through the exhaust pipe 110, completing the dehumidification work of the dehumidification cylinder 33. The dehumidification cylinder 33 continuously absorbs moisture from the oily exhaust gas, and then the moisture in the dehumidification cylinder 33 is carried away by the hot airflow. The dehumidification cylinder 33 continuously transports moisture, completing the dehumidification of the oily exhaust gas. During operation, the filter cylinder 24 rotates continuously, filtering oily fumes and exhaust gases. Dust accumulates on the inner wall of the filter cylinder 24. The rubber frame 19 rubs against the inner wall of the filter cylinder 24, and then the dust is discharged along the edge of the rubber frame 19 through the notch of the driven coil 29. The dust falls off the inner wall of the filter cylinder 24 and lands on the retractable end 11 at the bottom of the fixed box 1. The filter cylinder 24 continuously filters oily fumes and exhaust gases. During cleaning, the sliding frame 14 is pulled out from the retractable end 11 and the protective cover 12, and then the protective cover 12 is removed from the bottom of the retractable end 11. The dust is discharged through the bottom of the retractable end 11, completing the dust cleaning work.
