[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5The utility model provides a technical solution: a smoke furnace with a smoke filtering structure comprises a smoke chamber 1, a heating box 2 is welded to one side of the outer wall of the smoke chamber 1, one end of the outer wall of the smoke chamber 1 is connected to a smoke chamber 3 through a pipeline, a smoke exhaust box 4 is opened at the other end of the outer wall of the smoke chamber 1, a suction fan 5 is installed on the outer wall of the smoke exhaust box 4, a water tank 6 is opened under the smoke exhaust box 4, the smoke chamber 1, the smoke exhaust box 4 and the water tank 6 are welded as a whole, and a through hole connected to the smoke exhaust box 4 is opened on one side of the smoke chamber 1.

[0024] A push frame 101 is slidably connected to the top of the inner wall of the smoking chamber 1, and the push frame 101 is clamped and connected to a tray 102 through an arc-shaped mounting frame opened on the surface thereof. A reflux box 103 is opened below the tray 102, and the bottom of the reflux box 103 is overlapped on the top of the mounting frame welded between the inner walls of the smoking chamber 1. A smoke guide plate 104 is overlapped on one side of the inner wall of the smoking chamber 1 through a circular column opened on the surface thereof, and a first filter plate 105 is slidably connected to the other side of the inner wall of the smoking chamber 1 through a slide groove opened on the surface thereof.

[0025] The smoking chamber 3 includes a material discharge area 301 and a smoking area 302 , a spiral feed rod 303 is installed between the material discharge area 301 and the smoking area 302 , a baffle 304 is provided between the material discharge area 301 and the spiral feed rod 303 , and a resistance wire heating plate 305 is installed inside the smoking area 302 .

[0026] In this embodiment, Figure 3 As shown, a plurality of circular through holes are formed on the surface where the smoking chamber 1 and the heating box 2 are connected, and a heating plate 201 and a first fan 202 are respectively installed inside the heating box 2; compared with directly installing the heating device together with the baking area, when the external movable door is opened after subsequent food processing, the internal heat outflow may cause a hidden danger of high-temperature burns to the operator. The heating plate 201 is installed on the outside of the smoking chamber 1, and the heat generated by it can be collected into the inside through the through holes where the smoking chamber 1 is connected to it, and the first fan 202 on the rear side accelerates the circulation of heat, thereby improving the effect of rapid heating.

[0027] In this embodiment, Figure 3As shown, there is a certain gap between the push frame 101 and the smoke guide plate 104, and a cavity is formed between the smoke guide plate 104 and one end of the inner wall of the smoking chamber 1, and the smoke generating area 302 is connected to the cavity through a pipe; the gap between the push frame 101 and the smoke guide plate 104 is conducive to ensuring that the smoke guide plate 104 is not restricted when being disassembled, and the smoke flows directly into the smoking chamber 1 through the pipe. The smoke area suddenly rushes in, and some floating dust after combustion may be mixed and attached to the surface of the food. By utilizing the cavity formed between the smoke guide plate 104 and the smoking chamber 1, when the smoke flows into the cavity through the pipe, the smoke is dispersed and discharged again through several pores on the surface of the smoke guide plate 104, which ensures the uniformity of the smoke treatment on the surface during food processing, and effectively reduces the possibility that the smoke will be accompanied by combustible powder due to a large amount of internal circulation.

[0028] In this embodiment, Figure 3 and Figure 4 As shown, a plurality of holes for spreading smoke are provided on the surface of the smoke guide plate 104, and a second filter plate 106 is snap-connected in a groove on one side of the smoke guide plate 104; when smoke flows into the cavity formed between the smoke guide plate 104 and the smoking chamber 1, the second filter plate 106 uses glass fiber filter paper as filter material, which can effectively intercept harmful substances attached to the smoke, thereby improving the safety of the food processing process, and it can be washed and reused repeatedly to reduce costs.

[0029] In this embodiment, Figure 2 As shown, the surface of the baffle 304 is a quadrilateral inclined sliding surface, and the spiral feed rod 303 is rotatably connected to the lower part of the baffle 304 through an externally installed servo motor, and the resistance wire heating plate 305 is located below the shaft head of the spiral feed rod 303, and a second fan 306 is installed on one side of the resistance wire heating plate 305; the smoke is generated by burning sawdust, and the wood materials burned for different processed products are different. In order to reduce the tediousness of manually delivering sawdust repeatedly, the sawdust is poured into the inside of the unloading area 301, and its shape of wide at the top and narrow at the bottom can slow down the speed of the raw materials falling, and it is quadrilateral. The rectangular baffle 304 structure provides an effective way for the wood chips to flow into the spiral feed rod 303. The wood chips are orderly flowed into the front end along with the rotating blades of the spiral feed rod 303 and fall onto the surface of the resistance wire heating plate 305. The resistance heating wire inside the resistance wire heating plate 305 converts electrical energy into thermal energy, and the high temperature caused by the wood chips falling on the surface causes the wood chips to burn through an oxidation reaction and generate smoke. The second fan 306 on one side ensures that the flame inside the smoke-generating area 302 will not flow back, and at the same time accelerates the circulation of the internal smoke, effectively allowing the smoke to flow into the smoking chamber 1 through the pipeline.

[0030] In this embodiment, Figure 5As shown, the smoke exhaust box 4 is connected to one side of the water tank 6 through a nozzle pipe installed inside it, and the other side of the water tank 6 is connected to the bottom wall of the smoke exhaust box 4 through a water pump pipe opened inside it, and the suction fan 5 is connected to the inside of the smoke exhaust box 4 through the air inlet pipe opened therein, and the first filter plate 105 is horizontally located at one end of the pipe; when the air inlet of the suction fan 5 draws smoke inside the smoke exhaust box 4, the first filter plate 105 at the front end improves the protection of the suction fan 5. Usually, most equipment collects smoke from smoked food through The smoke is transported to the treatment equipment through the suction fan 5 and the pipeline or directly discharged to the outside. This treatment method may cause the container for the smoke equipment to be too large or cause too much smoke to be discharged into the air, causing environmental impact. The smoke exhaust box 4 and the water tank 6 are combined here. The water tank 6 is connected to the nozzle through the pipeline by a water pump to spray the smoke entering the smoke exhaust box 4, effectively reducing the smoke concentration and achieving the purpose of purification, making the final discharged smoke safer, and the water source dripping into the smoke exhaust box 4 is returned to the inside of the water tank 6 through the pipeline and the water pump again, and the recycling use is more energy-saving.

[0031] The use method and advantages of the utility model: When the smoke furnace with a smoke filtering structure is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, the food that needs to be coated with slurry is classified and laid flat on the surface of the tray 102. The tray 102 is the surface of the push frame 101 that is connected by snapping, which is convenient for daily disassembly and cleaning. At the same time, the push frame 101 is slidably connected to the inside of the smoking chamber 1 through a slide groove installed on the top of the smoking chamber 1, which is convenient for loading and unloading during daily use. The wood chips used for smoking are poured into the unloading area 301. When the food is treated on the surface of the tray 102, after the heating plate 201 is heated, the first fan 202 accelerates the circulation speed of the heat source, so that the heat is collected into the interior through the through hole on one side of the smoking chamber 1 to heat the food. During the heating process, the slurry on the surface and the grease itself will drip, and the dripping oil will flow into the interior of the reflux box 103. The reflux box 103 is placed on the surface of the mounting frame to ensure the cleanliness of the interior of the smoking chamber 1 and facilitate cleaning. During the heating process of food, the wood chips in the unloading area 301 will fall onto the surface of the spiral feeding rod 303, and the blades rotating with the spiral feeding rod 303 will fall onto the surface of the resistance wire heating plate 305. After the high temperature of the resistance wire heating plate 305, the surface wood chips will burn to generate smoke, and the smoke will flow into the cavity between the smoke guide plate 104 and the smoking chamber 1 through the pipeline, and the second filter plate 106 can effectively intercept and filter the powder impurities attached to the smoke, and the filtered smoke is then dispersed and discharged through the several air holes on the surface of the smoke guide plate 104 to process the food. At the same time, the second fan 306 ensures that the flame inside the smoke generating area 302 will not flow back, and accelerates the circulation of the internal smoke, effectively allowing the smoke to flow into the smoking chamber 1 through the pipeline. The processed smoke will flow into the interior of the smoke exhaust box 4 through the through holes on the surface of the first filter plate 105 under the action of the suction fan 5, and the first filter plate 105 improves the protection of the suction fan 5 to prevent a large amount of smoke from flowing into the smoke exhaust box The interior of the smoke exhaust box 4 is blocked, and the smoke entering the smoke exhaust box 4 will be processed by the nozzle to reduce its concentration value, and then discharged through the outlet pipe of the suction fan 5 and the pipe mouth or collection box laid outside, effectively reducing the smoke concentration value and the pollution degree in the air when the air is finally discharged, and the circulating water pipe of the water tank 6 and the smoke exhaust box 4 has an energy-saving effect. The smoke guide plate 104 is hung on the inner wall of the smoking chamber 1 through a column opened on the surface of the smoking chamber 1. When the second filter plate 106 needs to be cleaned, the smoke guide plate 104 is taken out and the second filter plate 106 engaged in its groove is disassembled.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
