Detailed Implementation

[0027] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0029] like Figures 1-6 As shown, this embodiment of the invention provides a heavy oil fume purification device for combustion of open flame lamps, including a lamp box 100 and a purification mechanism 200.

[0030] The interior of the lamp box 100 forms a space for the burning of an open flame lamp. In this embodiment, the open flame lamp is preferably a ghee lamp. Of course, in other embodiments, the open flame lamp can also be a candle or other oil lamp.

[0031] The purification mechanism 200 includes a fume hood 210, an exhaust fan 220 and a flue gas purification filter element 230 disposed inside the fume hood 210. The fume hood 210 is fixed to the top of the light box 100. The top of the fume hood 210 is provided with an exhaust port 211. The bottom of the fume hood 210 is connected to the top of the light box 100. The exhaust fan 220 is used to discharge the heavy oil fumes generated by the burning of the open flame lamp in the light box 100 upward from the fume hood 210. The flue gas purification filter element 230 is used to filter and purify the heavy oil fumes flowing through the fume hood 210.

[0032] This application designs the top cover of the light box 100 as a purification mechanism 200. When in use, the exhaust fan 220 is turned on, and the heavy oil fumes generated by the burning of the open flame lamp inside the light box 100 are discharged into the fume hood 210 through the exhaust fan 220. After the heavy oil fumes are filtered and purified by the fume purification filter element 230 inside the fan hood, they are discharged from the exhaust port 211 at the top. Therefore, this application can purify the heavy oil fumes generated by the burning of the open flame lamp in the first instance, reducing the pollution of the external environment caused by the discharge of heavy oil fumes.

[0033] In a preferred embodiment, refer to Figure 1 and Figure 2 The lower part of the light box 100 is provided with a lower vent 110, and the upper part of the light box 100 is provided with a high temperature buffer chamber 300. A heat insulation plate 400 is provided between the lower part of the high temperature buffer chamber 300 and the light box 100. A vent 410 is provided on the heat insulation plate 400. The upper part of the high temperature buffer chamber 300 is connected to the fume hood 210. An upper vent 310 is provided around the high temperature buffer chamber 300.

[0034] The exhaust fan 220 exhausts air upwards, so we set a lower vent 110 at the bottom of the light box 100. External air can enter the light box 100 through the lower vent 110 to supply oxygen for the open flame lamp combustion. When the exhaust fan 220 is started to exhaust air upwards, the high-temperature flue gas generated by the open flame lamp combustion flows upwards. The high-temperature flue gas will first encounter the heat insulation plate 400, and then enter the high-temperature buffer chamber 300 through the vent 410 on the heat insulation plate 400. Under the action of the exhaust fan 220, the external cold air enters the high-temperature buffer chamber 300 through the surrounding upper vent 310 and mixes with the high-temperature flue gas, thereby reducing the temperature of the flue gas. The low-temperature flue gas mixed with the cold air then enters the smoke exhaust hood 210 and is discharged after being filtered and purified by the flue gas purification filter element 230 in the smoke exhaust hood 210.

[0035] This application, by setting up a heat insulation plate 400, can prevent high-temperature flue gas from directly hitting the flue gas purification filter element 230. By setting up a high-temperature buffer chamber 300 and setting up ventilation holes 310 around the high-temperature buffer chamber 300, cold air can be drawn in and mixed with the flue gas during the exhaust process to reduce the temperature of the flue gas and prevent the flue gas purification filter element 230 from being burned due to excessively high temperature entering the exhaust hood 210. At the same time, it can also slow down the air intake speed of the lower ventilation hole 110 to prevent the airflow speed in the lamp box 100 from being too fast and causing the open flame lamp to be blown out.

[0036] Reference Figure 2 and Figure 6 The heat insulation plate 400 includes a specific outer frame 430, a central baffle 440 disposed within the outer frame 430, and a plurality of connecting strips 450 connecting the outer frame 430 and the central baffle 440. The central baffle 440 is located directly above the open flame lamp and can block the high-temperature flue gas generated by the combustion of the open flame lamp, preventing the high-temperature flue gas from directly rushing towards the flue gas purification filter element 230. After being blocked by the central baffle 440, the high-temperature flue gas enters the high-temperature buffer chamber 300 through the ventilation opening 410 formed between the outer frame 430 and the central baffle 440.

[0037] In this embodiment, refer to Figures 2-6 The bottom of the exhaust hood 210 is provided with a filter element mounting groove 212, and the flue gas purification filter element 230 is detachably installed in the filter element mounting groove 212. The upper side of the filter element mounting groove 212 is connected to a fan mounting cavity 213 for installing the exhaust fan 220.

[0038] To facilitate the opening and closing of the fixing ring 214, a fixing ring 214 is detachably installed at the bottom of the exhaust hood 210, which is pressed against the edge of the flue gas purification filter element 230. One side of the fixing ring 214 is hinged to the bottom of the exhaust hood 210, and the other side is connected to the bottom of the exhaust hood 210 by a buckle 215.

[0039] The light box 100 has an openable and closable door 120 on one side. The heat insulation plate 400 can be opened or closed from the inside of the light box 100. In order to facilitate the opening and closing of the heat insulation plate 400, one side of the heat insulation plate 400 is hinged to one side of the inside of the light box 100, and the other side of the heat insulation plate 400 is fixed to the other side of the inside of the light box 100 by a pin 420.

[0040] The flue gas purification filter element 230 needs to be replaced regularly. When replacing the flue gas purification filter element 230, first open the box door 120, then reach into the light box 100 and pull out the pin 420 on the heat insulation plate 400. Then turn down to open the heat insulation plate 400. After the heat insulation plate 400 is open, reach up into the high temperature buffer chamber 300 and open the buckle 215 on one side of the fixing ring 214. Then turn down the fixing ring 214 to remove the old flue gas purification filter element 230. After removing the old flue gas purification filter element 230, install the new flue gas purification filter element 230 into the filter element installation slot 212 at the bottom of the exhaust hood 210. Then cover the fixing ring 214, close the heat insulation plate 400 and the box door 120 in sequence to complete the filter element replacement. The filter element replacement is very convenient.

[0041] In this embodiment, refer to Figure 1 , Figure 2 and Figure 6 The lightbox 100 specifically includes an upper frame 130, a lower frame 140, and four columns 150 connecting the four corners of the upper frame 130 and the lower frame 140. The outer frame formed by the upper frame 130, the lower frame 140, and the columns 150 provides structural support. A door 120 is installed on one side of the lightbox 100 between the upper frame 130, the lower frame 140, and the columns 150. The door 120 is a transparent glass door. Transparent glass panels 160 are provided between the upper frame 130, the lower frame 140, and the columns 150 on the other three sides of the lightbox 100. The transparent glass around the lightbox allows light to pass through.

[0042] Preferably, the light box 100 further includes a bottom inner shell 170 and a bottom outer shell 180. The bottom inner shell 170 is closed at the lower end and has an opening at the upper end. The upper end of the bottom inner shell 170 is connected to the lower frame 140. The lower vent 110 is disposed around the bottom inner shell 170. The bottom outer shell 180 has openings at both the upper and lower ends. The bottom outer shell 180 surrounds the bottom inner shell 170. The upper end of the bottom outer shell 180 is connected to the lower frame 140. A ventilation gap is formed between the lower end of the bottom outer shell 180 and the bottom inner shell 170, thereby enabling air intake at the bottom of the light box 100.

[0043] In this embodiment, refer to Figure 2 and Figure 4 The smoke hood 210 is equipped with a baffle 240 located above the exhaust fan 220 and the smoke purification filter element 230. The baffle 240 can disrupt the airflow and slow down the smoke exhaust speed, thus preventing the chimney effect during the smoke exhaust process.

[0044] In this embodiment, refer to Figure 1 and Figure 2The exhaust hood 210 is covered with a decorative cover 250. The top of the decorative cover 250 is provided with a grille outlet 251 aligned with the exhaust port 211. The grille outlet 251 can meet the requirements for purifying the exhaust gas and also prevent external debris from entering the exhaust hood 210.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
