Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0045] refer to Figures 1 to 9 ,like Figure 1 and Figure 2 As shown, this embodiment provides a flue gas purification device for quenching oil tanks, mainly composed of a treatment box 100, a gas collecting hood 400, and an oil collecting box 6. The treatment box 100 is equipped with a purification structure, such as a filter screen and activated carbon, which can perform subsequent purification treatment on the flue gas. For details, refer to Chinese Patent CN215352743U. A fan 200 is installed on the treatment box 100, and an exhaust pipe 300 is connected to the fan 200. The lower end of the exhaust pipe 300 is connected to the gas collecting hood 400. The gas collecting hood 400 is composed of a gas collecting hood shell 1, a pair of plug-in mechanisms 2, and an oil guiding structure. The gas collecting hood shell 1 includes a cylindrical section 12, a flared section 11, and a rolled edge section 13 arranged sequentially from top to bottom. The pair of plug-in mechanisms 2 are arranged opposite to each other on the cylindrical section. On the outside of section 12, a placement groove 121 is provided inside the cylindrical section 12. The lower end of the suction pipe 300 can be accommodated in the placement groove 121. Two oppositely arranged slots 302 are provided on the outside of the suction pipe 300. A pair of insertion mechanisms 2 can be inserted into the corresponding slots 302, thereby realizing the fixed connection between the suction pipe 300 and the gas collection cover 1. The oil guiding structure is installed in the horn section 11. The oil collection box 6 is snapped onto the rolled edge section 13, and the oil collection box 6 is located on the outside of the oil guiding structure. An outwardly inclined oil outlet hole 111 is provided on the horn section 11. The oil outlet hole 111 is located between the oil collection box 6 and the oil guiding structure, so that the e-liquid collected on the oil guiding structure can flow smoothly into the oil collection box 6 through the oil guiding structure and the oil outlet hole 111.

[0046] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the insertion mechanism 2 consists of a mounting box 22, an operating component, and an insertion component. An arc-shaped base 21 is welded to the inner side of the mounting box 22. The base 21 is fixed to the outer side of the cylindrical section 12 by screws. The screw connection facilitates the disassembly of the insertion mechanism 2 from the gas collection hood 1. The operating component is located inside the mounting box 22. A door 23 is provided on the front side of the mounting box 22 for easy maintenance of the internal parts. The operating component consists of a screw 25, a first trapezoidal block 26, and a handle 24. The insertion component consists of a second trapezoidal block 27, a plug rod 29, and a compression spring 28. The upper end of the screw 25 is rotatably connected to the mounting box 22 via a bearing, and the lower end of the screw 25 is fixed to the bottom of the first slide groove 221 via a bearing seat. The first trapezoidal block 26 is threaded. The screw 25 is mounted on a first trapezoidal block 26, which is slidably engaged with the first slide groove 221 so that the rotation of the screw 25 can drive the first trapezoidal block 26 to move vertically. A handle 24 is installed at the upper end of the screw 25, which is located above the mounting box 22 for easy operation. The second trapezoidal block 27 is slidably disposed in the second slide groove 222 of the mounting box 22. The second slide groove 222 is located outside the first slide groove 221. The insertion rod 29 is fixed to the side of the second trapezoidal block 27 and extends horizontally. A compression spring 28 is sleeved on the insertion rod 29. The compression spring 28 abuts against the side wall of the second trapezoidal block 27 and the second slide groove 222. The insertion rod 29 can be inserted into the slot 302 to achieve a secure installation between the gas collection cover 1 and the exhaust pipe 300.

[0047] The method of use is as follows: Turn the handle 24 to rotate the screw 25, so that the first trapezoidal block 26 moves downward. When the first trapezoidal block 26 moves downward, it will squeeze the second trapezoidal block 27, so that the compression spring 28 is compressed. At the same time, the insertion rod 29 passes through the through hole on the base 21 and is inserted into the slot 302 of the suction pipe 300 in the placement slot 121. When it is necessary to disassemble the gas collection cover 1, reverse the handle 24, the first trapezoidal block 26 moves upward, the compression spring 28 returns to its original position, and drives the insertion rod 29 and the second trapezoidal block 27 to move outward. Then the insertion rod 29 disengages from the slot 302. At this time, the suction pipe 300 is separated from the insertion mechanism 2. The gas collection cover 1 together with the insertion mechanism 2 can be removed as a whole.

[0048] like Figure 3As shown, one or two limiting grooves 122 are formed on the inner side of the cylindrical section 12, and one or two limiting protrusions 301 are formed on the outer side of the suction pipe 300. The limiting protrusions 301 can be inserted into the corresponding limiting grooves 122. The limiting protrusions 301 and the limiting grooves 122 are matched to ensure that the limiting protrusions 301 are aligned with the limiting grooves 122 when the suction pipe 300 and the gas collection cover 1 are installed, which improves the positioning accuracy during installation and makes the installation operation more convenient. In addition, a sealing ring 123 is provided between the cylindrical section 12 and the suction pipe 300 to enhance the sealing effect at the connection between the two.

[0049] like Figure 2 , Figure 6 and Figure 7 As shown, the oil guiding structure consists of a first oil guiding cylinder 3, a second oil guiding cylinder 4, and a third oil guiding cylinder 5. The upper end of the second oil guiding cylinder 4 is fixed to the cylindrical section 12 by screws, and the lower end of the second oil guiding cylinder 4 is connected to the first oil guiding cylinder 3 by bolts and locked with nuts. Therefore, the positions of the first oil guiding cylinder 3 and the second oil guiding cylinder 4 are fixed. The third oil guiding cylinder 5 includes an integrally connected Z-shaped section 51 and a fixed section 52. The inner end of the Z-shaped section 51 extends to the inner side of the lower end of the first oil guiding cylinder 3 to receive the e-liquid dripping from the first oil guiding cylinder 3. The fixed section 52 is fixed... The Z-shaped section 51 is located inside the horn section 11 and has an oil receiving surface 511. The oil receiving surface 511 is connected to the oil outlet 111 opened on the horn section 11. An oil inlet 61 is opened on one side of the oil collection box 6. The oil inlet 61 is also connected to the oil outlet 111. The oil inlet 61 corresponds to the oil outlet 111 and is located on its outer side. Therefore, the e-liquid generated by the accumulation of smoke will drip onto the oil receiving surface 511 through the first oil guide tube 3 and the second oil guide tube 4. The e-liquid on the oil receiving surface 511 will flow into the oil collection box 6 through the oil outlet 111 and the oil inlet 61.

[0050] like Figure 9 As shown, the first oil guide cylinder 3 has several annularly arranged through holes 31, which allow flue gas to be drawn into the treatment box 100 through the exhaust pipe 300.

[0051] like Figure 7 and Figure 8As shown, an annular limiting spring 7 is installed inside the rolled edge section 13 of the gas collection cover 1. The annular limiting spring 7 consists of a mounting part 71, an elastic part 72, and an elbow 73. The mounting part 71 is fixed to the inner wall of the rolled edge section 13. The elastic part 72 extends arc-shaped from the upper end of the mounting part 71 towards the middle. The elbow 73 is arc-shaped and connected to the lower end of the elastic part 72. After bending, the elbow 73 protrudes towards the middle of the annular limiting spring 7. An annular groove 63 is opened on the outer side of the oil collection box 6. The elbow 73 can abut against the groove 63 to fix the oil collection box 6 to the rolled edge section 13. During use, the e-liquid level can be observed through the viewing window 62 on the oil collection box 6. When the e-liquid level is higher than the top of the viewing window 62, the oil collection box 6 needs to be removed. The annular limiting spring 7 is used to fix and restrict the oil collection box 6, allowing the user to install and remove the oil collection box 6 by simply inserting and removing it, making the operation convenient.

[0052] Working principle: When the fan 200 starts, when quenching produces oil fumes, the fan 200 draws the oil fumes into the exhaust pipe 300 through the through hole 31, and then collects them into the treatment box 100 through the exhaust pipe 300. The purification structure in the treatment box 100 can purify the oil fumes and reduce environmental pollution. The oil fumes will adhere to the inner and outer sides of the first oil guide cylinder 3 and the inner side of the second oil guide cylinder 4. When a lot of oil fumes accumulate, they will flow downwards along the inner and outer sides of the first oil guide cylinder 3 and the inner side of the second oil guide cylinder 4. Thus, the oil receiving surface 511 below the first oil guide cylinder 3 and the second oil guide cylinder 4 can collect the oil fumes, and then flow into the oil collection box 6 through the oil outlet 111 and the oil inlet 61. When the oil collection box 6 is full, it can be disassembled, cleaned, and then reinstalled. Normally, the oil collection box 6 can be disassembled and cleaned. The gas collection cover 1 can be disassembled and cleaned periodically. During disassembly, the gas collection cover 1 can be separated from the suction pipe 300 by operating the plug-in mechanism 2. The operation is convenient and easy.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
