Problems solved by technology

However, due to insufficient collision and capture of oil fume and oil mist, the oil droplets thrown on the inner wall of the housing are relatively limited, and a lot of oil fume and oil mist still flow out from the air outlet of the fan, resulting in poor purification effect of oil fume and oil mist

Embodiment 1

[0030] Embodiment one: if Figure 1 to Figure 5 As shown, the fan in this embodiment includes a casing 1 , a motor 2 , an end ring 3 , blades 4 , a middle plate 5 , an oil filter ring 6 and a motor mounting base 8 . Wherein, the opposite side of the casing 1 has an air inlet 11 and an air outlet 12, the end ring 3 and the blades 4 are arranged inside the casing 1, the end ring 3 is arranged on the side close to the air inlet 11 of the fan, and the middle plate 5 is arranged on the On the side close to the air outlet 12 of the fan, bayonets 9 are provided on the end ring 3 and the middle plate 5. Both ends of the blade 4 have clips 41. When installing, the clips 41 at one end of the blade snap into the ends of the end ring 3. In the bayonet socket 9, the claw foot 41 at the other end is stuck in the bayonet socket 9 of the middle plate 5, so that the blade, the end ring and the middle disk are fixed to form an impeller. The oil filter ring 6 includes an outer fixing ring 61 an...

Embodiment 2

[0033] Embodiment two, such as Figure 6 As shown, the oil filter ring 6 of this embodiment includes an inner fixing ring 63, an outer fixing ring 61, and an oil guide strip 62 arranged between the inner fixing ring and the outer fixing ring, wherein the inner fixing ring 63 is fixed on the center plate 5 There is a gap between the outer fixing ring 61 and the inner wall of the casing 1 . The rest of the structure is the same as that of the first embodiment, and will not be repeated here.

Embodiment 3

[0034] Embodiment three: as Figure 7 As shown, the oil guide strip 62 of the oil filter ring 6 of this embodiment adopts a grid structure. After adopting the grid structure, the probability of collision and capture of the oil fume in the mixed oil fume air can be increased. The rest of the structure is the same as that of the first embodiment. Here No longer.

Abstract

A fan comprises a machine case, a motor and an impeller, wherein the machine case is provided with an air inlet and an air outlet. The fan is characterized in that the impeller comprises an end ring, blades and a central disc. The end ring is arranged close to the side of the air inlet, the central disc is arranged on the side of the air outlet, the blades are fixed onto the end ring and the central disc, and the central disc is provided with oil filters which can synchronously rotate along with the central disc. Smoke-oil mixed air entering from the air inlet is collected inside the machine case through collision to form oil drops on the oil filter, and the oil drops are thrown onto the inner wall of the machine case under the action of the centrifugal force of the fan, and air with oil filtered outflows from the air outlet after passing through the oil filters. The fan has the advantage that the central disc and the oil filters are arranged on the side of the air outlet, the oil-smoke is collected through collision, under the action of the centrifugal force, the oil drops are thrown onto the inner wall of the machine case, and the separated and purified air passes through the oil filters and then outflows from the air outlet, so that the separation structure is simple and the separation effects are good.

Description

technical field [0001] The invention relates to a ventilation, oil fume separation and purification device, in particular to a fan. Background technique [0002] In metal processing, welding processing, food processing, catering and other industries, a large amount of mixed gas mixed with oil fume and oil mist will be produced. If the mixed gas is not properly treated, it will not only affect the physical and mental health of the operators, but also cause serious damage to the environment. pollute. For example, in the current integrated stoves and range hoods, a centrifugal fan composed of an air duct volute, a wind wheel, and a motor is generally used to extract and discharge oil fumes. The volute discharges directly into the air. Although some centrifugal fans are equipped with metal filter plates to filter oily fumes, a large amount of oily fumes will still be discharged into the air, causing air pollution. Moreover, after long-term use of centrifugal fans, the wind whe...
