Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment for fume treatment, in particular to an environmental protection equipment for fume treatment. Background Technique

[0002] The fume exhaust gas generated in occasions such as catering cooking and industrial treatment contains a large amount of pollutants, which not only pollutes the environment, is prone to cause the hood and pipeline to catch fire, but also is an "invisible killer" to human health. Fire smoke is the harmful gas emitted during the combustion of the stove, which is mainly free carbon black smoke, in a flocculent shape, easy to adhere to solid substances, and belongs to high-concentration soot gas. For people staying in the kitchen for a long time, these gases will inevitably cause certain harm. Therefore, it is necessary to treat the waste gas generated by kitchen fume. During the process of absorbing and treating fume, the absorption coverage range is an important factor in the design of environmental protection equipment for fume treatment. However, when the fume suction port is relatively large, the equipment volume is usually large. Therefore, we propose an environmental protection equipment for fume treatment, whose fume suction port diameter can be expanded during use, so that a smaller equipment can have a larger suction range to solve such problems.

[0017] The utility model provides an oil fume treatment environmental protection device with an expandable suction port. When oil fume is generated, the oil fume treatment device is started, the motor body is started, and the two rotating plates are driven to rotate at high speed, which generates a large suction force on the lower airflow, and a large amount of airflow carrying oil fume is sucked from a low place to a high place. At this time, the fan blade is pushed to rotate with the surge of the oil smoke airflow, which in turn drives the central fixed tube to rotate circumferentially. The bottom circle of the central fixed tube is tightly attached to the top of each folding plate but not connected. The linear track of the central fixed tube rotates with the central fixed tube, so that the slider of the central fixed tube rotates circumferentially in its respective track and moves upward at the same time (because the folding plate has a tendency to swing outward and spread when the bottom end of the central fixed tube rotates circumferentially), driving the top of the folding plate to move upward along the track on the conical surface of the central fixed tube, so that the top of the folding plate shrinks. Since the middle part of the folding plate is movably connected to the inner circle of the central connecting plate, the bottom of the folding plate expands outward, that is, the diameter of the circle surrounded by the top of the folding plate becomes smaller, and the diameter of the circle surrounded by the bottom becomes larger, that is, the diameter of the oil smoke suction port is larger, so that a wide range of oil smoke can be absorbed, so that the equipment can adapt to the treatment of a large amount of oil smoke. After opening and use, it will automatically fall and fold, and can be cleaned and repaired, which is convenient to operate. Brief Description of the Figures

[0029] Referring to Figure 2 and Figure 6 , the four rotating plates 6 are circumferentially distributed around the driving shaft 4 within 360°, located in the middle of the top rectangular box 1. The structure of the top rectangular box 1 is a rectangular pipe. A round hole is opened in the center of the middle connecting plate 9.

A middle fixed pipe slider 21 is movably connected to the inside of each outer middle fixed pipe track 20. Each middle fixed pipe slider 21 is fixedly connected to the top of a converging plate 15.

[0030] Referring to Figure 1, the structure of the bottom vertical rectangular box 3 is a rectangular pipe, which is located below the top rectangular box 1 and is vertically connected to the top rectangular box 1. A circular hole 10 is provided at the bottom of the top rectangular box 1, and an outlet pipe 7 is provided on one side of the top rectangular box 1. The lower end of the bottom vertical rectangular box 3 is fixedly connected to the middle connecting plate 9.

[0031] Refer to Figure 2 and Figure 3 , the middle main horizontal plate 8 and the middle auxiliary horizontal plate 11 are vertically connected. The middle main horizontal plate 8 and the middle auxiliary horizontal plate 11 are located at the top of the middle part of the bottom vertical rectangular box 3, and the bottom fixed shaft 12 is movably connected to the driving shaft 4.

[0032] Refer to Figure 4 , Figure 5 , the structure of the middle fixed pipe 13 is a hollow frustum, with a small diameter at the upper part and a large diameter at the lower part. The middle fixed pipe 13, the fan blade plate 14 and the middle outer ring 19 rotate together around the bottom fixed shaft 12. The large lower end of the middle fixed pipe 13 is in close contact with the top of each folding plate 15 but not connected.

[0033] Refer to Figure 5 , the two fan blade plates 14 are spiral belt-shaped, with a starting position staggered by 180°, and are fixedly installed between the middle fixed pipe 13 and the middle outer ring 19. The bottom limit disk 18 is located at the bottom of the middle outer ring 19, and the middle outer ring 19 is adapted to the bottom fixed shaft 12.

[0034] Refer to Figures 4 to 7 , the middle fixed pipe track 20 is spiral, with a spiral direction opposite to that of the fan blade plate 14. Each folding plate 15 is adjacent and in close contact but not connected, and there is a certain overlapping width between adjacent two folding plates 15.

[0035] Refer to Figure 6 , Figure 7 , each folding plate 15 moves around the folding slider 17 movably connected to it.

[0036] The working principle of the utility model is as follows: when oil smoke is generated, the oil smoke treatment equipment is started, the motor body 2 is started, and the rotating plate 6 is driven to rotate at a high speed, which generates a large suction force on the lower airflow, and a large amount of airflow carrying oil smoke is sucked from a low place to a high place. At this time, the fan blade plate 14 is pushed to rotate along with the surge of the oil smoke airflow, and the rotation of the fan blade plate 14 drives the rotation of the middle fixed tube 13. The bottom circle of the middle fixed tube 13 is tightly attached to the top of the multiple folding plates 15 but not connected. The middle fixed tube track 20 follows the rotation of the middle fixed tube 13, so that each middle fixed tube slider 21 rotates circumferentially in its own track and moves upward at the same time, driving the top of the folding plate 15 to move upward along the track 20 on the conical surface of the middle fixed tube. The middle part of the folding plate 15 is still connected to the middle connecting plate 9 through the folding slider 17. The block 17 slides relatively downward inside the folding slide rail 16, so that the top of the folding plate 15 shrinks. Since the middle of the folding plate 15 is movably connected to the inner circle of the middle connecting plate 9, the bottom of the folding plate 15 expands outward, that is, the diameter of the circle surrounded by the top of the folding plate 15 becomes smaller, and the diameter of the circle surrounded by the bottom becomes larger, that is, the diameter of the oil fume suction port is larger, so that a wide range of oil fume can be absorbed, so that the equipment can adapt to the treatment of a large amount of oil fume. After opening and using, it will automatically fall and fold, and can be cleaned and maintained, which is convenient to operate.
