Description

Technical Field

[0001] This utility model relates to the technical field of oil fume filtration equipment, specifically to an oil fume filtration and emission device. Background Technology

[0002] In the catering industry, such as restaurants, hotels, etc., a large amount of oily fumes are generated during the cooking and processing of food. The oily fumes contain water vapor, oil mist and fine particulate matter. In order to meet the requirements for oily fume emission, these impurities need to be filtered before being discharged.

[0003] Existing fume filtration equipment typically uses filter paper to filter oil fumes. However, because oil fumes contain moisture, the filter paper absorbs this moisture. Once the filter paper absorbs moisture, it deforms to some extent, significantly reducing its filtration efficiency.

[0004] Therefore, there is an urgent need for a new fume filtration and emission device. Utility Model Content

[0005] This utility model proposes an oil fume filtration and emission device, which solves the problem that the filtration effect of oil fumes in existing oil fume filtration and emission equipment is not up to standard due to the deformation of the filter paper caused by the adsorption of water vapor.

[0006] The technical solution of this utility model is as follows: an oil fume filtration and emission device, comprising:

[0007] The housing has an internal filter chamber with an air inlet and an air outlet, both of which are connected to the outside of the housing. The air inlet faces the source of kitchen fumes.

[0008] The first filter paper is inclinedly disposed in the filter cavity and located between the air inlet and the air outlet. The first filter paper is used to filter water vapor in the oil fumes.

[0009] A support is disposed within the filter chamber and in contact with the first filter paper, the support being used to support the first filter paper;

[0010] The second filter paper is inclinedly disposed in the filter chamber and located between the support and the air outlet. The second filter paper is used to filter particulate matter in the oil fume.

[0011] A first fan is disposed within the filter chamber and is used to generate airflow within the housing.

[0012] As a further technical solution, an installation plate is also included, which is disposed inside the filter chamber, and the first filter paper, the bracket and the second filter paper are all fixed on the installation plate by means of insertion and removal.

[0013] As a further technical solution, there are two mounting plates arranged symmetrically, and each mounting plate has a slot for inserting the ends of the first filter paper, the bracket, and the second filter paper.

[0014] As a further technical solution, a replacement plate is also included. The housing has a replacement port facing the first filter paper, the support and the second filter paper. The replacement plate is snapped onto the housing and covers the replacement port.

[0015] As a further technical solution, the first fan is located between the second filter paper and the air outlet.

[0016] As a further technical solution, the inner wall of the filter cavity located between the second filter paper and the first fan is constricted.

[0017] As a further technical solution, a temperature alarm is also included, which is mounted on the housing and has its detection end extending into the filter chamber.

[0018] As a further technical solution, a cooling component is also included. The interior of the housing is provided with a cooling cavity, which has a cooling inlet and a cooling outlet. The cooling component includes a second fan, which is disposed inside the cooling cavity.

[0019] As a further technical solution, the first fan and the second fan are symmetrically arranged inside the housing, and a heat-conducting plate is provided between the cooling chamber and the filter chamber.

[0020] As a further technical solution, a sealing ring is also included, which is located outside the housing and wraps around the air inlet in a ring shape.

[0021] The working principle and beneficial effects of this utility model are as follows: An oil fume filtration and emission device includes a housing, a first filter paper, a support, a second filter paper, and a first fan. The housing has a filtration chamber with an inlet and an outlet. The inlet faces the source of the oil fume in the kitchen, and both the inlet and outlet connect to the outside of the housing. The first filter paper is placed inside the filtration chamber to filter water vapor from the oil fume, and the second filter paper is placed inside the filtration chamber to filter particulate matter from the oil fume. After filtration by the first and second filter papers, the remaining gas can be discharged into the external space. The first fan is placed inside the filtration chamber to provide airflow. The airflow carries the oil fume into the housing through the inlet, and then, after filtration, it is discharged into the atmosphere. In this process, to increase the filtration area of ​​the first and second filter papers, both the first and second filter papers are inclined. Furthermore, because the first filter paper is inclined, the moisture on it can flow away under its own weight, thereby reducing the moisture content and increasing its service life. Furthermore, since the first filter paper is used to filter water vapor in the fumes, and since the first filter paper will deform after absorbing water vapor, a support is set below the first filter paper. The support is also set at an angle. The function of the support is to provide support for the first filter paper, so as to prevent the first filter paper from deforming after absorbing water vapor, which would lead to a decrease in the filtration effect, and thus indirectly improve the service life of the second filter paper.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figures 1 to 8 As shown, this embodiment proposes an oil fume filtration and emission device, including:

[0034] The housing 1 has an internal filter chamber with an air inlet 2 and an air outlet 3. Both the air inlet 2 and the air outlet 3 are connected to the outside of the housing 1, and the air inlet 2 faces the place where the kitchen fumes are generated.

[0035] The first filter paper 4 is inclinedly disposed in the filter chamber and located between the air inlet 2 and the air outlet 3. The first filter paper 4 is used to filter water vapor in the oil fumes.

[0036] The bracket 5 is disposed inside the filter chamber and keeps in contact with the first filter paper 4. The bracket 5 is used to support the first filter paper 4.

[0037] The second filter paper 6 is inclinedly disposed in the filter chamber and located between the support 5 and the air outlet 3. The second filter paper 6 is used to filter particulate matter in the oil fume.

[0038] The first fan 7 is installed inside the filter chamber and is used to generate airflow inside the housing 1.

[0039] In this embodiment,

[0040] Furthermore, such as Figures 5-8 As shown, this embodiment also includes a mounting plate 8, which is disposed inside the filter chamber. The first filter paper 4, the bracket 5, and the second filter paper 6 are all fixed to the mounting plate 8 by means of insertion and removal.

[0041] In this embodiment, an oil fume filtration and emission device includes a housing 1, a first filter paper 4, a support 5, a second filter paper 6, and a first fan 7. The housing 1 has an internal filtration chamber with an inlet 2 and an outlet 3. The inlet 2 faces the source of the oil fumes in the kitchen, and both the inlet 2 and the outlet 3 connect to the outside of the housing 1. The first filter paper 4 is disposed within the filtration chamber and filters moisture from the oil fumes. The second filter paper 6 is disposed within the filtration chamber and filters particulate matter from the oil fumes. After filtration by the first and second filter papers 4 and 6, the remaining gas can be discharged into the external space. The first fan 7 is disposed within the filtration chamber and provides airflow to the filtration chamber. The airflow carrying the oil fumes enters the housing 1 through the inlet 2, is then filtered, and finally discharged into the atmosphere. In this process, to increase the filtration area of ​​the first filter paper 4 and the second filter paper 6, both the first filter paper 4 and the second filter paper 6 are inclined. Furthermore, because the first filter paper 4 is inclined, the moisture on it can flow under its own weight, thus reducing the moisture content and extending its service life. Also, since the first filter paper 4 is used to filter water vapor from oil fumes, and it deforms after absorbing water vapor, a support 5 is installed below it. The support 5 is also inclined, providing support to the first filter paper 4 and preventing it from deforming after absorbing water vapor, which would reduce its filtration efficiency and indirectly extend the service life of the second filter paper 6.

[0042] Furthermore, such as Figures 6-7 As shown, this embodiment proposes two mounting plates 8 arranged symmetrically. The mounting plates 8 are provided with slots for inserting the ends of the first filter paper 4, the bracket 5, and the second filter paper 6.

[0043] In this embodiment, to facilitate the replacement and maintenance of the first filter paper 4, the support 5, and the second filter paper 6, mounting plates 8 are provided inside the filter chamber. Two mounting plates 8 are attached to the inner wall of the filter chamber. Each mounting plate 8 has two slots, resulting in four slots in total. The symmetrically arranged slots correspond to either the combination of the first filter paper 4 and the support 5 or the second filter paper 6. This pull-out installation method facilitates the rapid replacement of the first filter paper 4, the support 5, and the second filter paper 6.

[0044] It should be noted that the first filter paper 4 and the second filter paper 6 involved in this utility model both have a certain degree of rigidity and are not the kind of soft filter paper structure.

[0045] Furthermore, such as Figures 4-5 As shown, this embodiment also includes a replacement plate 9. The housing 1 has a replacement port facing the first filter paper 4, the bracket 5, and the second filter paper 6. The replacement plate 9 is attached to the housing 1 and covers the replacement port.

[0046] In this embodiment, to further improve the efficiency and convenience of replacing the first filter paper 4 and the second filter paper 6, a replacement port is provided on the housing 1, facing the first filter paper 4 and the second filter paper 6. The integrated fume filtration and emission device also includes a replacement plate 9, which is snap-fitted onto the housing 1 and covers the replacement port. This arrangement facilitates the replacement of the first filter paper 4 and the second filter paper 6 located in the filtration chamber and also prevents external impurities from entering the housing 1.

[0047] Furthermore, such as Figure 8 As shown in the figure, this embodiment proposes that the first fan 7 is located between the second filter paper 6 and the air outlet 3.

[0048] In this embodiment, to optimize the internal space of the housing 1 and the position of each component within the filter chamber, the first fan 7 is positioned between the second filter paper 6 and the air outlet 3. This arrangement also facilitates gas flow, preventing gas turbulence during filtration and thus ensuring a good filtration effect.

[0049] Furthermore, such as Figure 8 As shown, in this embodiment, the inner wall of the filter cavity located between the second filter paper 6 and the first fan 7 is constricted.

[0050] In this embodiment, in order to increase the flow rate of air in the filter chamber, the inner wall of the filter chamber located between the second filter paper 6 and the first fan 7 is set to a constricted shape. This constricted shape is conducive to the gas passing through the first filter paper 4 and the second filter paper 6.

[0051] Furthermore, such as Figures 1-3 As shown, this embodiment also includes a temperature alarm 10, which is mounted on the housing 1 and has its detection end extending into the filter chamber.

[0052] In this embodiment, when the temperature of the exhaust fumes is too high, it will damage the first fan 7. Therefore, when the temperature of the fumes is too high, it is necessary to stop the operation of the first fan 7 or take external cooling measures. To this end, the fume filtration and emission device also includes a temperature alarm 10 and a controller. The temperature alarm 10 is installed on the housing 1, and the detection end of the temperature alarm 10 extends into the filter chamber of the housing 1. The temperature alarm 10 and the first fan 7 are both electrically connected to the controller. When the temperature of the fumes is too high, the temperature alarm 10 will transmit a signal to the controller, and the controller will control the first fan 7 to stop rotating, thereby protecting the first fan 7.

[0053] Furthermore, such as Figure 8As shown, this embodiment also includes a cooling component, and a cooling cavity 11 is provided inside the housing 1. The cooling cavity 11 has a cooling inlet and a cooling outlet. The cooling component includes a second fan 12, which is disposed inside the cooling cavity 11.

[0054] In this embodiment, in order to treat the oil fumes even when the temperature is high, the oil fume filtration and emission device also includes a cooling component. The housing 1 has a cooling chamber 11 inside, which has a cooling inlet and a cooling outlet. The cooling component includes a second fan 12. The second fan 12 forms an external airflow channel in the cooling chamber 11 by suction and exhaust, thereby cooling the entire housing 1 and ultimately cooling the oil fumes in the filtration chamber.

[0055] Furthermore, such as Figure 8 As shown in the figure, this embodiment proposes that the first fan 7 and the second fan 12 are symmetrically arranged inside the housing 1, and a heat-conducting plate is provided between the cooling cavity 11 and the filter cavity.

[0056] In this embodiment, since the first fan 7 and the second fan 12 are provided inside the housing 1, in order to keep the overall center of gravity of the oil fume filtration and emission device low, the first fan 7 and the second fan 12 are arranged symmetrically inside the housing 1. In order to reduce the complexity of the internal structure of the housing 1, a heat-conducting plate is provided between the cooling chamber 11 and the filter chamber. It is equivalent to sharing a heat-conducting plate, which can form a filter channel and a cooling channel. Since the heat-conducting plate has good thermal conductivity, the gas in the cooling channel can have a good cooling effect on the gas in the filter channel.

[0057] Furthermore, such as Figures 1-2 As shown, this embodiment also includes a sealing ring 13, which is located outside the housing 1 and wraps around the air inlet 2 in a ring shape.

[0058] In this embodiment, in order to improve air tightness, a sealing ring 13 is provided at the air inlet 2 of the housing 1. When the housing 1 is installed on other structures, the sealing ring 13 can play a good sealing role, thereby improving the operating efficiency of the first fan 7.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
