Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust pipes, in particular to a smoke exhaust pipe with oil smoke filtering. Background Art

[0002] The exhaust pipe is a pipe system that allows waste gas, smoke and other harmful substances generated inside the equipment to be discharged promptly and effectively, ensuring the cleanliness and safety of indoor air, avoiding the dangers of fire or poisoning caused by smoke accumulation, and maintaining the normal operation of the equipment or system.

[0003] When in use, the existing smoke exhaust pipe cannot filter the oil smoke, which will cause pollutants such as grease and particulate matter in the oil smoke to be directly discharged, polluting the atmospheric environment and increasing harmful substances in the air. In addition, long-term emission of unfiltered oil smoke will cause grease to accumulate in the smoke exhaust pipe, increasing the fire hazard. At the same time, it will also accelerate the corrosion of the pipe, shorten its service life, and even affect the working efficiency of the smoke exhaust system, resulting in poor smoke exhaust.

[0004] In response to the above problems, we have launched a smoke exhaust pipe with oil fume filtration. Utility Model Content

[0005] The utility model discloses a smoke exhaust pipe with oil smoke filtering, aiming to solve the technical problem that the oil smoke cannot be filtered.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A filter box is set up to collect and filter the oil smoke generated by the oven to ensure the cleanliness of the exhaust gas. The oven is located below the filter box, and the smoke is guided to the filter box through the exhaust duct. The outer tube is connected to the filter box, and the inner tube can be slid and adjusted. The oil filter box is installed in the filter box to filter the grease in the smoke. The oil collection box is located below the oil filter box to collect the grease filtered by the oil filter box to ensure that the grease does not enter the air during the exhaust process. At the same time, it is convenient for the centralized treatment and regular cleaning of the grease to maintain the efficiency and cleanliness of the filtration system.

[0009] In a preferred solution, a flange is fixedly connected to the top of the filter box, and the filter box is fixedly connected to the smoke exhaust duct through the flange.

[0010] By arranging a flange on the top of the filter box, the filter box is firmly connected to the smoke exhaust duct through the flange, ensuring the sealing of the connection, avoiding smoke leakage, and improving the stability and safety of the device.

[0011] In a preferred solution, the top of the outer tube is fixedly connected to the bottom of the filter box by fastening screws.

[0012] By setting the outer pipe to be fixedly connected to the bottom of the filter box through fastening screws, the stability and reliability of the pipeline system are ensured, preventing loosening or falling off during the smoke exhaust process, and improving the durability of the device.

[0013] In a preferred embodiment, a connecting joint is threadedly connected to the bottom of the outer tube and located on the outside of the inner tube, and a ball bearing is fixedly connected to the top of the inner tube and located inside the outer tube, and the ball bearing is slidably connected to the inner wall of the outer tube.

[0014] The bottom of the outer tube is threadedly connected to the inner tube through a connecting joint, and the ball bearing is located at the top of the inner tube for sliding connection with the inner wall of the outer tube, ensuring that the inner tube can smoothly adjust its position and facilitating adjustment of the length of the smoke exhaust pipe as needed.

[0015] In a preferred solution, the bottom of the inner tube is threadedly connected to an oil receiving bowl.

[0016] An oil collecting bowl is provided at the bottom of the inner tube through a threaded connection to collect oil droplets in the oil smoke, thereby preventing grease from entering the exhaust system and preventing grease accumulation from corroding the outer tube and the inner tube.

[0017] In a preferred solution, handles are fixedly connected to the bottoms of both sides of the indoor tube.

[0018] By installing handles at the bottom of both sides of the inner tube, it is convenient for the operator to hold and operate the inner tube easily when adjusting the position of the inner tube, so that the length of the inner tube can be easily adjusted.

[0019] In a preferred embodiment, one side of the filter box is connected to a connecting door via a hinge, one side of the filter box is fixedly connected to two openers and closers, one side of the connecting door is fixedly connected to two buckles, and the openers and closers are used in conjunction with corresponding buckles.

[0020] A connecting door is hinged on one side of the filter box, which is easy to open for inspection or replacement of the oil filter box. The opener and the buckle are used in conjunction to ensure that the connecting door is firmly sealed when closed to prevent oil smoke from leaking out, making maintenance and cleaning easier and ensuring the sealing performance of the filter box.

[0021] The utility model provides a smoke exhaust pipe with oil smoke filtering, which has the following advantages:

[0022] The smoke from the smoke filter is filtered out by the smoke filter, and the smoke from the smoke filter is filtered out by the oil filter box when passing through the filter box. The filtered smoke continues to enter the smoke duct upward and is discharged through the smoke duct. On the one hand, it has its own smoke filter, which can reduce the smoke in the discharged smoke and reduce the accumulation of smoke in the smoke pipe, thereby reducing safety hazards and reducing the pollution of the smoke to the environment. On the other hand, the smoke treatment equipment is burdened by the modular design of the smoke pipe and the filter box, and the split connection makes installation and disassembly convenient and transportation and cleaning convenient. The smoke pipe can be disassembled and cleaned separately, which reduces the difficulty of cleaning and maintenance. The appearance is stylish, novel, simple and generous, which greatly improves the operation quality and use efficiency compared with traditional devices. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the outer tube 4 is hung on the lower end of the filter box 1 and fixed by the fastening screws 9. The flange 8 at the upper end of the filter box 1 is installed to weld the box body to the corresponding position on the exhaust duct 3. Hold the handle 13 with both hands to pull the inner tube 5 up and down to adjust the length of the smoke pipe. When in use, the flue fan generates negative pressure to suck air outward. The oil smoke generated by baking food in the oven 2 is sucked into the smoke pipe with the airflow and discharged into the exhaust through the filter box 1. In the pipeline, when the flue gas passes through the smoke pipe, a small amount of oil smoke will condense on the wall of the smoke pipe. These oil smoke will flow into the oil receiving bowl 12 along the pipe wall, and the other oil smoke will continue to reach the filter box 1 upward, and the smoke will enter the oil filter box 6. The inside of the oil filter box 6 is composed of multiple metal plates stacked to form a tortuous flue gas channel to slow down and cool the smoke. Most of the oil smoke in the smoke will condense on the metal plates and drip into the oil collecting box 7 at the bottom of the oil filter box 6. The remaining smoke will continue to enter the exhaust duct 3 upward and be discharged with the flue. Regularly check and clean the filter element, regularly check and clean the oil collecting box 7 and the oil receiving bowl 12, and scrub the surface of the smoke pipe every day to reduce the oil smoke in the exhaust gas, reduce the accumulation of oil smoke in the exhaust pipe, reduce safety hazards, and reduce the pollution of smoke to the environment.
