Specifically, the filter box 11 is composed of two halves of the box connected together. The smoke inlet 111 at the bottom of the filter box 11 is bent to one side. Two corner plates 18 for box installation are also provided on one side of the filter box 11. The number of activated carbon filter plates 14 is 1-3 layers. The activated carbon filter plates 14 are filled with high-efficiency activated carbon. Through the adsorption of high-efficiency activated carbon, organic volatiles such as toluene and xylene in the hot smoke are effectively removed.

[0032] The bottom of the filter box 11 is provided with a smoke inlet 111. The flue baffle 13 includes an arc plate 131 and a first curved plate 132 and a second curved plate 133 in a vortex shape. Specifically, the first curved plate 132 and the second curved plate 133 have the same structure and are rotationally symmetrical. One end of the arc plate 131 is attached to the second curved plate 133, and the other end of the arc plate 131 is attached to the inner wall of the filter box 11. The activated carbon filter plate 14 is located above the flue baffle 13, and the spray element 12 is located in the middle of the first curved plate 132 and the second curved plate 133.

[0033] The filter box 11 is located above the activated carbon filter plate 14 and is also connected to an air extraction component 15. The air extraction component 15 draws the smoky smoke into the filter box 11 through the channel formed by the flue partition 13, and then filters the smoky smoke through the spray component 12 and the activated carbon filter plate 14.

[0034] In this embodiment, the outer end of the first bent plate 132 is attached to one side of the inner wall of the filter box 11, and the outer end of the second bent plate 133 is attached to the other side of the inner wall of the filter box 11. The inner side of the first bent plate 132 and the outer side of the second bent plate 133, together with the arc plate 131, form a smoke inlet channel, and the outer side of the first bent plate 132 and the inner side of the second bent plate 133 form a smoke outlet channel.

[0035] The smoke inlet channel is provided with multiple flow-damping plates 16 and multiple filter screens 17 in sequence along the smoke inlet direction. Specifically, the number of flow-damping plates 16 and filter screens 17 is set to 1-3. The flow-damping plates 16 reduce the flow rate of the hot pot smoke entering the smoke inlet channel, and the filter screens 17 perform preliminary filtration of the hot pot smoke to remove large particles such as hot pot foil residue. The flow-damping plates 16 are provided with multiple ventilation holes in a rectangular array. Specifically, the number of ventilation holes is 16-24. The filter screens 17 are made of metal and an electric current can be applied to the filter screens 17 to achieve the effect of electrostatic dust removal.

[0036] In this embodiment, the spraying component 12 includes a spray pipe 121, a plurality of diverter plates 122 arranged in a ring on the spray pipe 121, and a plurality of spray heads 123. The spray heads 123 are linearly arranged between adjacent diverter plates 122. Specifically, the number of diverter plates 122 is 4-8, and the number of spray heads 123 arranged between adjacent diverter plates 122 is 4-12. The spray pipe 121 and the diverter plates 122 are rotatably disposed in the middle of the first curved plate 132 and the second curved plate 133.

[0037] One end of the spray pipe 121 is rotatably connected to the outlet pipe 124. The outlet pipe 124 passes through the filter box 11 and is connected to it. The filter box 11 is provided with a storage tank 125 outside the outlet pipe 124. A water pump 126 is installed on one side of the storage tank 125. The input end of the water pump 126 is connected to the inlet pipe 127 and extends to the bottom of the storage tank 125. The output end of the water pump 126 is connected to the outlet pipe 124.

[0038] The filter box 11 is located below the liquid outlet pipe 124 and has a discharge port 112. The bottom of the discharge port 112 is flush with the inner side of the first curved plate 132. The top of the liquid storage tank 125 is provided with a liquid inlet and the bottom of the liquid storage tank 125 is provided with a liquid outlet.

[0039] It should be noted that a neutral potassium iodide solution can be added to the storage tank 125 through the inlet. The solution is delivered by a water pump 126 and sprayed from the spray head 123 on the spray pipe 121 to contact the scalding smoke. The potassium iodide solution removes the metal vapors from the scalding smoke, mainly mercury vapors. The filtered solution after the reaction collects at the bottom of the first curved plate 132 and flows back into the storage tank 125 through the outlet 112. After the filtered solution is saturated, it is discharged and replaced through the outlet of the storage tank 125.

[0042] S1. Install two filter components 1 on both sides of the heating plate of the hot stamping machine, add filter liquid into the liquid storage tank 125 through the liquid inlet, and start the air pump 152 and water pump 126 of the filter components 1 when the hot stamping machine is performing hot stamping processing.

[0043] S2. The water pump 126 draws the filtrate from the storage tank 125 and delivers it to the spray pipe 121, where the spray head 123 sprays the filtrate outward.

[0044] S3. Air is drawn out of the filter box 11 by the air pump 152. The hot stamping smoke generated by the hot stamping machine enters the filter box 11 through the smoke inlet 111, then enters the smoke inlet channel, passes through the flow plate 16 to reduce the flow rate, and then passes through the filter screen 17 for preliminary filtration to remove large particles in the hot stamping smoke.

[0045] S4. The hot smoke flows out of the smoke inlet channel and pushes the diversion plate 122 and the spray pipe 121 to rotate. The diversion plate 122 separates the hot smoke into the chamber between adjacent diversion plates 122, so that the hot smoke can fully contact the filter liquid and remove the metal vapor in the hot smoke.

[0046] S5. The scalding smoke flows out from the smoke outlet channel and flows to the activated carbon filter plate 14. The scalding smoke passes through the activated carbon filter plate 14. Through the adsorption of the activated carbon filter plate 14, the volatile organic compounds in the scalding smoke are removed.
