The embodiment of the utility model provides an oil smoke purifier for supplying 5 thousand people's large-scale kitchen use.

Referring to fig. 1 and 2, fig. 1 is a schematic perspective view of an oil smoke purifying device 100 according to an embodiment of the present invention, and fig. 2 is a top view of the oil smoke purifying device 100 according to an embodiment of the present invention. The direction indicated by arrow a in fig. 1 and 2 is the flow direction of the oil smoke gas when the oil smoke is sucked into the oil smoke purifying apparatus 100 by the fan 3, the direction indicated by arrow B is the direction in which the flow of the oil smoke gas changes due to the difference in pressure, and the direction indicated by arrow C above the fan wheel 4 in fig. 1 is the rotation direction of the fan wheel 4. An embodiment of the utility model provides an oil smoke purifier 100 includes purification tank 1 and locates the purification channel 2 of 1 tops of purification tank, and wherein purification tank 1 is the pond of the device bottom, and purification channel 2 sets up in purification tank 1 tops in oil smoke purifier 100, and purification channel 2 is the passageway that fuel feeding cigarette flows in it. The purification tank 1 has a drain opening 91, the purification passage 2 has an inlet 21 and an outlet 22, and a fan 3 is provided at the inlet 21. As shown in fig. 2, the oil smoke purifying apparatus 100 is disposed to communicate with the flue 110, specifically, the inlet 21 communicates with the smoke exhaust outlet of the flue 110, and the fan 3 draws the oil smoke in the flue 110 into the oil smoke purifying apparatus 100, purifies the oil smoke through the purifying passage 2, and then discharges the oil smoke from the outlet 22. It should be noted that, the number of the fans is not limited, and the number of the fans and the power of the fans can be set and selected according to the size of the kitchen and the actual needs.

In the purifying channel 2, after the fan 3 sucks in the oil smoke from the inlet 21, the oil smoke enters the purifying channel 2 along the direction of arrow a, then the oil smoke flows collide with the side wall of the oil smoke purifying device 100 opposite to the inlet 21 and return, the oil smoke flows accumulate near the inlet 21, the pressure of the air flow accumulated near the inlet 21 gradually increases until the pressure is larger than that at the outlet 22, the air flow is forced to flow towards the outlet 22 due to the pressure difference, therefore, the oil smoke changes in the purifying channel 2 and flows along the direction of arrow B, and the direction in which the oil smoke flows and is discharged from the outlet 22 after changing is the first direction (shown in the direction X in fig. 1 and 2). Optionally, at least three rows of fan wheels 4 are arranged upstream of the outlet 22, the three rows of fan wheels 4 are arranged at intervals along the first direction X, the rotation directions of two adjacent rows of fan wheels 4 are opposite, and a spray header 5 is arranged above the fan wheels 4 in the purifying channel 2. When the oil smoke passes through the fan wheel 4 in the purification channel 2, the atomized spray water generated by the spray header 5 is used for spraying and washing the oil smoke sucked into the purification channel 2 from the flue 110, so that the oil drops in the oil smoke are settled into the purification tank 1 to purify the oil smoke. Because the rotation directions of the two adjacent rows of fan wheels 4 are opposite, when oil smoke passes through the fan wheels 4, a plurality of vortexes are formed between the fan wheels 4, the speed reduction effect is achieved, the contact time of the oil smoke and water mist is prolonged, it is ensured that oil drops in the oil smoke have enough time to contact with water and fall into a water pool together with the water, and therefore the oil smoke is fully purified. It should be noted that the number of rows of fan wheels 4 and the number of fan wheels 4 in each row may be set according to the size of the kitchen and the actual needs. In the present embodiment, five rows of fan wheels 4 are provided, the number of each row of fan wheels 4 being in turn 6, 5, 6.

Specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of a fan wheel 4 according to an embodiment of the present invention. The fan wheel 4 includes a fan wheel shaft 41 and fan blades 42, and part of the fan blades 42 has a plurality of holes 43 on the fan wheel shaft 41 side. The fan shaft 41 is fixedly installed in a hole of a bracket 44 (see fig. 1), the bracket 44 is a rectangular frame, the duct 6 is arranged above the bracket 44, and the fan blades 42 rotate around the fan shaft 41 under the blowing of the oil fume flow. In this embodiment, the number of the fan blades 42 is 3, and the number of the fan blades may be set according to the size of the kitchen and the actual requirement. In order to allow the oil smoke to pass through the fan wheel 4, a plurality of holes 43 are provided at intervals on the fan blade 42 on the side close to the fan wheel shaft 41, and the holes 43 are square. More specifically, the number of blades 42 having holes is greater than the number of blades 42 having no holes. In this embodiment, blades 42 are 3, of which 2 blades 42 are provided with holes 43 and 1 blade 42 is not provided with holes. With this arrangement, the fumes can flow in the first direction X through the holes 43 to flow to the next row of fan wheels 4 and to be flushed again by the showers 5 above the fan wheels 4, finally being discharged from the outlet 22. However, because each fan blade 42 is not provided with the hole 43, the oil smoke is retained between the two rows of fan wheels 4, the retention time of the oil smoke in the area is increased, the water and the oil smoke are ensured to be fully contacted, and the purification effect is improved.

Specifically, two adjacent rows of fan wheels 4 in the fan wheels 4 are staggered along the first direction X, and since the sizes of the fan blades in this embodiment can be set to be substantially the same, the staggered arrangement of the fan wheels 4 can be realized by staggering the fan wheel shafts 41 of the fan wheels 4, that is, the fan wheel shaft 41 of the fan wheel 4 in the back row is located in the middle or on one side of the two adjacent fan wheel shafts 41 of the fan wheel 4 in the front row.

More specifically, of the blades 42 of two adjacent rows of fan wheels 4, the bending direction of one row of blades 42 is opposite to the bending direction of the other row of blades 42. Thus, when the oil fume gas flows through the area of the fan wheel 4, the fan wheel 4 rotates under the blowing of the air flow, and the bending directions of the fan blades 42 are different, so that the rotating directions of two adjacent rows of fan wheels 4 are different, namely if the first row of fan wheels 4 rotates forwards, the second row of fan wheels 4 rotates backwards, the third row of fan wheels 4 rotates forwards, and so on. Therefore, when the oil smoke passes through the area of the fan wheel 4, a vortex is formed between the two rows of fan wheels 4, so that the oil smoke can be decelerated, the contact time of the oil smoke and the water mist is prolonged, and the purification effect is improved.

More specifically, the shower head 5 is connected to the purification tank 1 through a pipe 6. The pipeline 6 is connected with a water outlet of a water pump (not shown) positioned in the purifying tank 1, and the water pump is communicated with the purifying tank 1. Therefore, water in the purifying tank 1 is pumped into the pipeline 6 through the water pump, water mist is sprayed out from the spray header 5 to scour the oil smoke, oil drops in the oil smoke fall into the purifying tank 1 together with the water, the water returns to the purifying tank 1, and the water is recycled. Referring to fig. 4, fig. 4 is a side view of the isolation cover according to the present embodiment. The water pump is covered with a shield 61, and the outer side surface of the shield 61 except the bottom surface is a cube of a mesh cover as shown in fig. 4. The isolation cover 61 is used for protecting the water pump and preventing impurities in the purification tank 1 from entering the isolation cover 61 to block the water inlet of the water pump.

With continued reference to fig. 1, the lampblack purification device 100 further comprises a water replenishing assembly 7 arranged upstream of the fan wheel 4, wherein the water replenishing assembly 7 comprises a water replenishing spray head 71, a water replenishing pipeline 72 and a water replenishing control valve 73, and the water replenishing pipeline 72 is connected with the water replenishing spray head 71 and the water replenishing control valve 73. The above-mentioned refill unit 7 is located in the purge path 2 with the refill shower head 71 on the upstream side of the shower head 5. Further, one end of the water replenishing pipe 72 is connected to a water supply pipe, which may be a tap water pipe. The water replenishing control valve 73 is a floating ball control valve for monitoring the water level of the purification tank 1 and adjusting the water level as required. When the water level in the purification tank 1 is lower than the preset water level, the water replenishing spray header 71 is opened to ensure that the water quantity in the purification tank 1 is sufficient, and meanwhile, the water replenishing spray header 71 can prolong the contact time of water mist and oil smoke, so that oil drops in the oil smoke can be accelerated to quickly sink into the water tank.

Referring to fig. 5 and 6, fig. 5 is a schematic structural view of a drainage grid 9 and a drainage grid 8 according to an embodiment of the present invention, and fig. 6 is a partially enlarged perspective view of the drainage grid 9 and the drainage grid 8 according to an embodiment of the present invention. Specifically, this practical novel oil smoke purifier 100 still includes blowdown check 8 and blowdown export 81 of locating in purification tank 1, and blowdown export 81 is located blowdown check 8 bottoms. More specifically, the outer wall of the dirt discharge grid 8 in the purification tank 1 comprises a first side wall 82A and a second side wall 82B, and the height of the first side wall 82A is lower than that of the second side wall 82B. After the oil smoke is atomized and sprayed, the water-oil mixture falls into the purifying tank 1, the water in the purifying tank 1 becomes impure, and oil stains float on the water surface. When the oil stain in the purification tank 1 is too much, the water level is adjusted to be high through the water supplementing control valve 73, and when the water level is higher than the first side wall 82A of the sewage discharging grid 8, the oil stain floating on the water level flows into the sewage discharging grid 8 through the first side wall 82A and is discharged into the sewage treatment tank through the sewage discharging outlet 81. The discharged oil stain can be purified and recycled.

Specifically, the lampblack purification device 100 further comprises a drainage grid 9 arranged in the pollution discharge grid 8 and a flow guide pipe 92 communicated with the bottom of the purification pool 1. The guide pipe 92 is used for guiding the water in the purifying tank 1 to the drainage grid 9. The water outlet 91 is positioned at the bottom of the water discharge grid 9 and is used for discharging water in the purifying tank 1. A drain switch (not shown) is provided in the flow pipe 92, and when the water in the purification tank 1 needs to be replaced, the drain switch is turned on, and the water in the purification tank 1 flows into the drain grid 9 through the flow pipe 92 by the pressure of the water and can be discharged through the drain port 91. More specifically, the drainage grid 9 is formed by partitioning the downstream side of the drainage grid 8 by a partition wall 82C in the drainage grid 8, and the height of the partition wall 82C is lower than the height of the first side wall 82A and the second side wall 82B of the drainage grid 8. When the blowdown was operated, because first side wall 82A is higher than second side wall 82B, the oil stain can not flow in drainage check 9, but when the export was plugged up by the oil stain to blowdown export 81, the oil stain was piled up in drainage check 8, when walking over partition wall 82C, the oil stain flows in drainage check 9 in, the oil stain can be followed drainage check 9 and discharged, and can not flow backwards in purification tank 1.

Further, since the oil stain floats on the water surface, crucian and chub which are favorable for eating oil can be kept in the purifying pond 1. Because the water in the purifying tank 1 is circularly sprayed, the oxygen content of the water in the purifying tank 1 can be ensured to be sufficient, and therefore, the required oxygen can be provided for the fish in the purifying tank 1. Crucian carp and silver carp like eating oil, and can quickly swallow oil stain on water surface, thereby achieving the ecological and environment-friendly purification effect. In order to remove oil stains on the water surface, a chemical agent for removing oil stains, a filter plate for filtering oil stains, or the like may be added to the purification tank 1.

The water in the purification tank 1 is pumped into the pipeline 6 by the water pump, so that the water in the purification tank 1 can be recycled. Meanwhile, when the oil smoke passes through the area of the fan wheel 4, the fan wheel 4 decelerates the oil smoke, the contact time of the oil smoke and the water mist is prolonged, the oil smoke is sufficiently purified, and therefore air without the oil smoke is discharged. In addition, the water replenishment control valve 73 monitors the level of the water in the purification tank 1, and when the water in the purification tank 1 is insufficient, the water replenishment pipe 72 communicates with the water supply pipe, and the water replenishment shower head 71 operates to replenish the water in the purification tank 1 and wash out the soot. When the oil stain of the surface of water of purification tank 1 was too much, heightened the water level, utilized moisturizing subassembly 7 to carry out the moisturizing, when the water level was higher than first side wall 82A's height, floated the oil stain on the surface of water and flowed into in the blowdown check 8 and carried out the blowdown. When the water in the purification tank 1 needs to be replaced, the drain switch is turned on, and the water flows into the drain compartment 9 through the guide duct 92 and is discharged through the drain port 91.

The oil fume purification device of the utility model sprays and erodes the oil fume through the atomized water, so that the oil fume is separated from the gas, and the oil fume can be purified; because the rotating directions of the two adjacent rows of fan wheels 4 are opposite, eddy currents are generated between the fan wheels 4 to decelerate the oil smoke, the contact time of the oil smoke and water mist is prolonged, the purification effect is improved, and the oil smoke can be fully purified even when the oil smoke amount is large. In addition, the utility model discloses a fan wheel 4 blow and rotate through the oil smoke gas stream, need not electric power, can the energy saving.
