Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification, and more specifically, particularly relates to a building flue water retaining structure and an 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 CN113565001A 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 utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0026] Embodiment 1:

[0027] A building flue water retaining structure is mainly used to block the flue opening when the oil fume purifier is spraying and cleaning, so as to prevent the dripping spray liquid from entering the flue. The main body of the building flue water retaining structure is a vertical flue 2, which has a flue inlet 1 connected thereto, and the shape and size of the flue inlet 1 are adapted to the exhaust port of the building public flue, so as to facilitate direct docking and installation.

[0028] In order to receive the spray liquid, Figure 1 Figure 2 As shown, a water collecting tank 3 is provided on the inner wall of the vertical flue 2. In order to achieve water blocking, as Figure 2 As shown, a water shield 4 and a support mechanism 5 for controlling the expansion / closure of the water shield 4 are provided in the vertical flue 2. The expansion / closure of the water shield 4 is controlled by the support mechanism 5 according to different usage scenarios.

[0029] Specifically, when in normal use, such as Figure 1 As shown, the water shield 4 is closed, so that the oil smoke discharged from the flue inlet 1 can flow upward to the oil smoke purifier above the vertical flue 2 for purification. The closed water shield 4 will not cause a large obstruction to the flow of smoke, which is conducive to the adsorption of oil smoke by the purifier.

[0030] When the oil fume purifier above the vertical flue 2 needs to be sprayed and cleaned, Figure 2 As shown, the support mechanism 5 pushes the water shield 4 to expand in all directions, and its orthographic projection completely covers the flue inlet 1, so that the spray liquid dripping from the vertical flue 2 flows along the edges of the water shield 4 to the water collection tank 3. The active closure method is adopted to prevent the spray liquid from entering the flue. Finally, a drain pipe 9 is also installed on the water collection tank 3, and the spray liquid collected in the water collection tank 3 is discharged to the outside through the drain pipe 9.

[0031] Preferably, when the water shield 4 is unfolded, the shape of the water shield 4 is the same as the shape of the flue inlet 1. For example, when the flue inlet 1 is square, the umbrella of the water shield 4 should also be square. For another example, when the flue inlet 1 is circular, the umbrella of the water shield 4 should also be circular. In this way, the material of the water shield 4 can be reduced, and a better shielding effect can be achieved.

[0032] In addition, if Figure 1 Figure 2 As shown, the flue inlet 1 is square, the vertical flue 2 is in the shape of a square tube, and the water collecting tank 3 is a U-shaped tank arranged on the inner wall of the vertical flue 2 and surrounded by it. Such a design can be integrated and save materials required for production.

[0033] In the above structure, the water shield 4 is in the shape of an umbrella. Figure 3 As shown, the support mechanism 5 includes an umbrella pole 51, a plurality of umbrella ribs 52 and a driving device 6. A plurality of sliding grooves 53 are provided on the umbrella pole 51, and a connecting seat 54 is slidably installed in the umbrella pole 51. Figure 4 As shown, a plurality of connecting ears 55 are provided on the connecting seat 54, and the plurality of connecting ears 55 slide through the plurality of sliding grooves 53 respectively, and a support rod 56 is respectively connected between the rib 52 and the connecting ears 55 in a hinged manner. That is, one end of the support rod 56 is hingedly mounted on the connecting ear 55, and the other end is hingedly mounted on the outer wall of the rib 52. It should be noted that the number and connection of the rib 52, the support rod 56 and the connecting ears 55 are one-to-one corresponding.

[0034] like Figure 5 As shown, the driving device 6 is connected to the connecting seat 54 through a connecting rod 61, so that the driving device 6 can drive the connecting seat 54 to move up and down, thereby achieving the purpose of unfolding and closing the water shield 4.

[0035] The specific driving device 6 is a servo electric cylinder with a guide rod, and of course the driving device 6 is not limited to an electric cylinder, and can be an electric push rod, or a pneumatic cylinder if there are corresponding conditions. The specific form can vary according to the actual situation.

[0036] In terms of installation, Figure 1 As shown, the support mechanism 5 further includes a cross beam 57 arranged in the vertical flue 2 , and the driving device 6 is vertically mounted on the cross beam 57 . The support mechanism 5 is connected to the driving device 6 and is also mounted on the cross beam 57 .

[0037] Embodiment 2:

[0038] A fume purifier, this embodiment includes the building flue water retaining structure in embodiment 1, such as Figure 6 As shown, a flue outlet 7 is provided above the vertical flue 2, and an oil fume purifier is provided between the building flue water retaining structure and the flue outlet 7, 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 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 the nozzle sprays water or cleaning liquid to spray and rinse the oil fume purifier.

[0039] 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 8 is provided at the corresponding flue outlet 7 , and the protective cover 8 is used to shield the top of the flue outlet 7 and guide the airflow of the flue outlet 7 to be discharged outward along the edge of the protective cover 8 .

[0040] 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.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
