Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, and particularly relates to a fully metal oil fume purification and filtering device. Background Art

[0002] An electrostatic oil fume purifier is installed in the flue of a restaurant kitchen. The electrostatic oil fume purifier can filter out the oil stains in the smoke generated in the kitchen, effectively prevent the smoke generated in the kitchen from polluting the outdoor air, and effectively improve the environmental protection of kitchen work. The existing electrostatic oil fume purifier is as Figure 1 shown. The electrostatic oil fume purifier is installed in the middle or end of the flue. This setting causes a large amount of oil stains to deposit on the wall surface of the flue section from the exhaust outlet of the smoke hood to the electrostatic oil fume purifier. It is very inconvenient to clean this narrow flue section, and the deposited oil stains are also likely to cause fire hazards. At the same time, when the electrostatic oil fume purifier is being cleaned, it requires a special person to climb up high or go to the top floor of the building for disassembly and installation. The disassembly and installation work is relatively cumbersome, the work efficiency is low, the cleaning workload is large, and the cleaning cost is high. Content of the Utility Model

[0003] To solve the above problems, especially the deficiencies of the prior art, the utility model provides a fully metal oil fume purification and filtering device that can solve the above problems.

[0004] To achieve the above object, the utility model adopts the following technical means:

[0005] A fully metal oil fume purification and filtering device includes a fixed frame. A filter element fixing frame housing is inserted into the fixed frame. A ventilation baffle is connected to the side of the filter element fixing frame housing away from the fixed frame. The ventilation baffle and the filter element fixing frame housing are both fixedly connected to the fixed frame through fixing wires. A plurality of groups of uniformly distributed filter element surrounding tubes that penetrate the filter element fixing frame housing are connected inside the filter element fixing frame housing. A second filter element grid is connected inside the penetrating end of the filter element surrounding tube. A steel wool filter element is stuffed inside the filter element surrounding tube. The ventilation baffle is provided with a plurality of groups of uniformly distributed ventilation openings that correspond to the plurality of groups of filter element surrounding tubes one by one. A first filter element grid connected to the ventilation baffle is arranged inside the ventilation opening.

[0006] A further scheme of the utility model is that the wind baffle, the first filter element grid, the filter element fixing frame housing, the filter element surrounding tube, the second filter element grid, the fixed frame, and the fixing wire are all made of stainless steel.

[0007] A further scheme of the utility model is that the ventilation baffle and the first filter element grid are integrally made.

[0008] A further scheme of the utility model is that the filter element surrounding tube is welded to the filter element fixing frame housing.

[0009] A further solution of the present utility model is that the steel wool filter element is made of irregular or circular stainless steel metal wires.

[0010] A further solution of the present utility model is that the fixing wire consists of a butterfly screw and a butterfly nut, and the butterfly screw is in threaded connection with the butterfly nut.

[0011] Advantages of the present utility model:

[0012] 1. The present utility model is installed at the exhaust air outlet of the smoke hood. Through a physical interception and filtration solution, the suction of the original flue fan at the exhaust air outlet of the smoke hood is used to directly intercept and filter the oil fume and oil stains, directly filtering and intercepting the oil fume and oil stains from the source, greatly reducing the entry of oil fume and oil stains into the flue and being discharged into the air, reducing air pollution, greatly reducing the accumulation of oil fume and oil stains on the inner wall of the flue, reducing the fire hazard of the flue, greatly reducing the frequency of cleaning the inner wall of the flue, and reducing the flue cleaning cost.

[0013] 2. When the present utility model is cleaned, due to the setting of the exhaust air outlet of the smoke hood, there is no need for a special person to climb to a high place for work, the workload is low, and when disassembling and assembling, only the ventilation baffle and the filter element fixing frame housing need to be disassembled and assembled, and the disassembly and assembly work is relatively simple and trivial, and the work efficiency is high.

[0014] 3. When too much oil fume and oil stains accumulate in the present utility model, the ventilation baffle can be directly disassembled and a new and low-cost steel wool filter element can be replaced. The replaced steel wool filter element can be reused after being cleaned, thereby effectively reducing the cleaning work and effectively reducing the cleaning cost. Description of the Drawings

[0024] Embodiment 1

[0025] As shown in the attached Figure 2 to the attached Figure 4 figures, the present utility model provides a full-metal fume purification and filtration device, which includes a fixed frame 8. A filter element fixing frame housing 4 is inserted into the fixed frame 8. A ventilation baffle 1 is connected to the side of the filter element fixing frame housing 4 away from the fixed frame 8. Both the ventilation baffle 1 and the filter element fixing frame housing 4 are fixedly connected to the fixed frame 8 through fixing wires 9. A plurality of groups of uniformly distributed filter element surrounding tubes 5 that penetrate the filter element fixing frame housing 4 are connected inside the filter element fixing frame housing 4. A second filter element grid 6 is connected inside the penetrating end of the filter element surrounding tube 5. Steel wool filters 7 are stuffed inside the filter element surrounding tubes 5.

A first filter element grid 3 connected to the ventilation baffle 1 is provided inside the ventilation openings 2.

[0026] Working principle

[0027] After the overall all-metal oil fume purification and filtration device is fixed at the exhaust air outlet of the smoke hood, the oil fume and oil stains enter the filter element surrounding pipe 5 through the ventilation port 2 under the suction of the fan in the flue. After being purified and filtered by the steel wool filter element 7 in the filter element surrounding pipe 5, the purified air enters the flue through the ventilation port on the filter element fixing frame housing 4 corresponding to the filter element surrounding pipe 5, and the clean air is discharged from the end of the flue.

[0028] After the steel wool filter element 7 has intercepted and filtered a large amount of oil fume and oil stains, unscrew the fixing wire 9 fixed on the lower plane of the fixing frame 8, remove the ventilation baffle 1 and the filter element fixing frame housing 4. After taking out the steel wool filter element 7 that has adsorbed the oil fume and oil stains, refill a new steel wool filter element 7. The new steel wool filter element 7 compresses the filter element surrounding pipe 5 and makes the filter element surrounding pipe 5 opaque. Then, fix the ventilation baffle 1 and the filter element fixing frame housing 4 on the lower plane of the fixing frame 8 with the fixing wire 9 again, and that's it.

[0035] The filter element surrounding pipe 5 is welded to the filter element fixing frame housing 4. This setting can effectively improve the tightness between the filter element surrounding pipe 5 and the filter element fixing frame housing 4, and can effectively prevent the fracture phenomenon between the filter element surrounding pipe 5 and the filter element fixing frame housing 4.

[0036] The steel wool filter element 7 is made of irregular or circular stainless steel wires. This setting can facilitate the production of the steel wool filter element 7 and can effectively reduce the use cost of the steel wool filter element 7.
