Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification, and more specifically, particularly relates to a water retaining structure for a self-cleaning oil fume purifier and the oil fume purifier. Background Art

[0002] In a building, kitchen exhaust enters the public flue. The oil fume in the public flue contains a large number of oily particles. If these oily particles are directly discharged into the atmosphere without being treated, it will cause serious pollution to the atmosphere. There are also technical solutions to solve the corresponding problems in the prior art. For example, the Chinese invention patent with publication number CN113465001A sets up oil fume purification equipment outside the public flue, and uses the electrostatic adsorption device to decompose the liquid oil pollution. Under the action of gravity, it first settles into the guide groove, and then flows into the oil collection box through the guide groove for collection, while the clean air is discharged through the flue outlet. At the same time, in order to ensure the improvement of oil fume purification efficiency and avoid short circuit and fire of the equipment, a cleaning nozzle is configured in the oil fume purification box to realize the self-cleaning function of the equipment.

[0003] When the equipment is self-cleaning, spray liquid will be generated. In order to prevent the spray liquid from entering the flue, the prior art uses a plurality of oil guide grooves arranged in the same direction in an alternating manner in multiple layers in the installation cavity of the oil guide device. However, after analysis, it is found that the oil guide grooves will block the flue gas and affect the flow of flue gas during normal fume purification. In order to solve this problem, a structure is needed to block the spray liquid from entering the flue without affecting the normal flow of flue gas. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] Embodiment 1:

[0027] A water retaining structure for a self-cleaning oil fume purifier is mainly used to prevent dripping spray liquid from entering the flue when the oil fume purifier is spraying and cleaning. Figure 1As shown, the water retaining structure includes a vertical flue 2 communicating with a flue inlet 1, and the shape and size of the flue inlet 1 are adapted to the smoke exhaust port of the public flue of the building, so as to be easy to install and use.

[0028] In order to receive the spray liquid, Figure 1-Figure 4 As shown, a water collecting trough 3 is provided on the inner wall of the vertical flue 2, and a water baffle 4 is provided near the water collecting trough 3. The water baffle 4 is connected to a driving mechanism. In normal state, the driving mechanism pushes the water baffle 4 to flip to the first mode, so that the oil smoke discharged from the flue inlet 1 flows upward to the oil fume purifier above the vertical flue 2 for purification. The first mode water baffle 4 is fully open, without any obstruction, and will not hinder the flow of smoke, which is conducive to the adsorption of oil smoke by the purifier. When the oil fume purifier above the vertical flue 2 needs to be sprayed and cleaned, the driving mechanism pushes the water baffle 4 to flip to the second mode, and the water baffle 4 blocks the flue inlet 1, so that the spray liquid dripping from the top of the vertical flue 2 flows into the water collecting trough 3 along the water baffle 4, and an active closing method is adopted to prevent the spray liquid from entering the flue.

[0029] In a preferred embodiment, the flue inlet 1 is square, the vertical flue 2 is square tube-shaped, and the water collecting tank 3 is a U-shaped groove arranged on the inner wall of the vertical flue 2 and surrounded by the water collecting tank 3. Such a design can not only be integrated, but also the flue inlet 1 and the vertical flue 2 are square, which is conducive to the cooperation with the water retaining plate 4.

[0030] It should be noted that, in the second mode, the orthographic projection area of ​​the water baffle 4 is larger than the flue inlet 1 , so that the water baffle 4 can completely block the flue inlet 1 .

[0031] In the second mode, the water baffle 4 needs to block the flue inlet 1. Considering the installation space in the vertical flue 2, the water baffle 4 should not be designed to be too long. Figure 2-Figure 5 As shown, the water baffle 4 can be designed as multiple pieces. Preferably, the water baffle 4 is designed as a first baffle 41 and a second baffle 42 that are arranged opposite to each other on the left and right, wherein the lower end of the first baffle 41 is hinged on the left groove edge of the water collecting tank 3, and the lower end of the second baffle 42 is hinged on the right groove edge of the water collecting tank 3.

[0032] Among them, the pushing mechanism is a conventional mechanical structure, and there are many types that can achieve this function. In this embodiment, a kind of Figure 5As shown, the pushing mechanism includes a vertical telescopic mechanism, a first connecting arm 5 and a second connecting arm 6. The first connecting arm 5 is hinged between the first baffle 41 and the vertical telescopic mechanism, and the second connecting arm 6 is hinged between the second baffle 42 and the vertical telescopic mechanism. The vertical telescopic mechanism here also includes various styles, such as electric push rods, cylinders, servo electric cylinders with guide rods and other components. The vertical telescopic mechanism used in this embodiment is a servo electric cylinder with guide rods 9, which is connected to the first connecting arm 5 and the second connecting arm 6 through a connecting member 13 on the telescopic arm of the servo electric cylinder with guide rods 9. Through the telescopic movement of the servo electric cylinder with guide rods 9, the connecting member 13 pushes the first connecting arm 5 and the second connecting arm 6, so that the first baffle 41 and the second baffle 42 are flipped.

[0033] When the oil fume purification equipment is in the self-cleaning spray cleaning, in order to ensure that the sewage can be completely blocked from entering the oil fume duct, the problem of the tightness of the first baffle 41 and the second baffle 42 is considered. Figure 1-Figure 4 As shown, a water receiving ditch 7 is provided between the first baffle 41 and the second baffle 42, and the water receiving ditch 7 is suspended by a bracket, and both ends thereof exceed the flue inlet 1. In the second mode, the gap between the upper edges of the first baffle 41 and the second baffle 42 is smaller than the opening of the ditch mouth of the water receiving ditch 7 and is located directly above the ditch mouth of the water receiving ditch 7. In this way, the spray liquid leaking from the gap is collected by the water receiving ditch 7, and the spray liquid in the water receiving ditch 7 flows from both ends to the water collecting tank 3. Finally, a drain pipe 8 is also installed on the water collecting tank 3, and the water collecting tank 3 is discharged to the outside through the drain pipe 8.

[0034] Embodiment 2:

[0035] A fume purifier, this embodiment adopts the water retaining structure in the first embodiment, such as Figure 6 As shown, a flue outlet 10 is provided above the vertical flue 2, and an oil fume purifier is provided between the water retaining structure and the flue outlet 10, and the oil fume purifier is equipped with a spray-type self-cleaning device. The oil fume purifier may adopt an electrostatic adsorption device, which is a plurality of electrode sheets that are interlaced and non-contacting with each other. When the oil fume passes through, it is adsorbed by generating an electrostatic field. The spray-type self-cleaning device may adopt a nozzle, which is connected to a water pump through a pipeline, and sprays water or cleaning liquid to rinse the oil fume purifier.

[0036] This oil fume purifier is directly installed on the public flue of the building. Considering that rainwater will enter the flue on rainy days, Figure 6 As shown, a protective cover 11 is provided at the corresponding flue outlet 10, and the protective cover 11 is used to shield the top of the flue outlet 10 and guide the airflow of the flue outlet 10 to be discharged outward along the edge of the protective cover 11. In order to prevent other foreign objects from entering the flue, a protective net 12 is also provided between the protective cover 11 and the vertical flue 2 to enclose the flue outlet 10.

[0037] The oil fume purifier can improve the oil fume purification efficiency and avoid equipment short circuit and fire through spray self-cleaning. During spray self-cleaning, it can ensure that the spray liquid will not enter the flue, which is extremely practical.
