Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification, and more specifically, particularly relates to a cleaning liquid collecting device and a direct-discharge 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

[0004] In view of the deficiencies in the prior art, the utility model provides a cleaning liquid collecting device and a direct exhaust type oil fume purifier to solve the technical problems described in the background technology.

[0014] Optionally, a protective cover is provided corresponding to the flue outlet, and the protective cover is used to shield the top of the flue outlet and guide the airflow of the flue outlet to be discharged outward along the edge of the protective cover.

[0015] The utility model provides a cleaning liquid collecting device and a direct exhaust type oil fume purifier, which has the following

[0016] Beneficial effects:

DETAILED DESCRIPTION

[0026] 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.

[0027] Embodiment 1:

[0028] A cleaning liquid collecting device is mainly used to prevent dripping spray liquid (cleaning liquid) from entering the flue when the oil fume purifier is spraying and cleaning. Figure 1 As shown, the cleaning liquid collecting device has a vertical flue 2 communicated 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.

[0029] In order to collect the spray liquid, a water collecting tank 3 is arranged on the inner wall of the vertical flue 2, and a plurality of reversible blades 4 are arranged above the water collecting tank 3. The blades 4 are arranged in a stepped manner, and a reversing mechanism is connected to the blades 4. In normal state, Figure 2 As shown, several blades 4 are in a side-lying state, 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. Under normal circumstances, all blades 4 are vertically distributed, and their plate surfaces are along the vertical flue 2. In this way, the blades 4 will not cause a large obstruction to the circulation of smoke, which is beneficial 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 3 As shown, the flipping mechanism pushes the blade 4 to flip, and several blades 4 overlap in sequence along the sides to form an inclined surface to block the flue inlet 1. In layman's terms, the lower edge of the upper blade 4 overlaps the upper edge of the next blade 4 to form a tile-like structure, whose positive projection completely covers the flue inlet 1, so that the spray liquid dripping from the top of the vertical flue 2 flows into the water collection tank 3 along the inclined surface, and an active closing method is adopted to prevent the spray liquid from entering the flue. Finally, a drain pipe 10 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 10.

[0031] The blade 4 can be directly mounted on the inner wall of the vertical flue 2 through the rotating shaft, or can be mounted on the inner wall of the vertical flue 2 through the rotating shaft. Figure 1-Figure 3 As described above, a mounting frame 14 is provided in the vertical flue 2, such as Figure 4 As shown, a plurality of blades 4 are provided with a rotating shaft 15 at both ends, and the plurality of blades 4 are mounted on a mounting frame 14 through the rotating shaft 15, so that the blades 4 can be flipped. The mounting frame 14 here can be mounted on the water collecting tank 3 in the vertical flue 2, or it can be mounted on the inner wall of the vertical flue 2.

[0032] In order to make the inclined surface have better tightness, such as Figure 3 Figure 4 As shown, the cross section of the blade 4 can be designed to be in a "Z" shape. When overlapped, adjacent blades 4 are interlocked with each other, which is helpful to prevent the spray liquid from seeping down the inclined surface.

[0033] Regarding the flipping mechanism, there are many styles of flipping mechanisms, such as a chain type (not shown), where a gear is set at one end of each blade 4, all the gears are connected to a chain, and a motor is used to drive the chain to rotate to achieve synchronous flipping of each blade 4. Figure 2-Figure 5As shown, the flip mechanism used in this embodiment includes a rocker 5 fixed at at least one end of the blade 4, and a plurality of rockers 5 on the same side are hingedly mounted on a long strip driving plate 6, and the hinge points are evenly distributed along the length direction of the driving plate 6. A slide groove 7 is provided on the plate surface of the driving plate 6 and along its length direction. A "7"-shaped transmission rod 8 is slidably installed in the slide groove 7, and the transmission rod 8 is connected to a vertical telescopic mechanism. The vertical telescopic mechanism adopts a servo electric cylinder 9 with a guide rod. Of course, the vertical telescopic mechanism is not limited to this mechanism, and a cylinder, an electric push rod, etc. can also be used, which can be considered as appropriate according to the actual application scenario.

[0034] The installation of the above-mentioned slide groove 7 and the transmission rod 8 is as follows Figure 5 As shown, in order to ensure smooth sliding, a track wheel 13 can be installed in the slide groove 7, and the end of the transmission rod 8 serves as the rotating shaft of the track wheel 13.

[0035] It should be noted that in order to ensure smooth flipping of the blade 4 and uniform force, a rocker 5, a drive plate 6 and a vertical telescopic mechanism can be set at both ends of the blade 4. The two vertical telescopic mechanisms move synchronously to flip the blade 4 (only single-side drive is shown in the figure).

[0036] In the above structure, if Figure 1 As shown, the flue inlet 1 is square, and the vertical flue 2 is also square tube-shaped. The water collecting tank 3 is preferably 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 matching the shape of the blade 4.

[0037] Embodiment 2:

[0038] A direct exhaust oil fume purifier, this embodiment adopts the cleaning liquid collecting device in the first embodiment, that is, a flue outlet 11 is arranged above the vertical flue 2, and an oil fume purifier is arranged between the cleaning liquid collecting device and the flue outlet 11, and the oil fume purifier is equipped with a spray-type self-cleaning device. Among them, the oil fume purifier can 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 can adopt a nozzle, which is connected to a water pump through a pipeline, and sprays water or cleaning liquid to spray and rinse the oil fume purifier.

[0039] This direct exhaust 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 12 is provided at the corresponding flue outlet 11 , and the protective cover 12 is used to shield the top of the flue outlet 11 and guide the airflow of the flue outlet 11 to be discharged outward along the edge of the protective cover 12 .

[0040] This direct exhaust fume purifier can improve the fume purification efficiency and avoid equipment short circuit and fire through spray self-cleaning. Spray self-cleaning 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.
