Combined lampblack intercepting net disc, range hood and range hood with fan

Abstract

The invention discloses a combined lampblack intercepting net disc, a range hood and a range hood with a fan. The combined lampblack intercepting net disc comprises a framework disc and a fan blade disc, the framework disc comprises a plurality of framework spokes which are distributed in a circumferential direction, the fan blade disc comprises a plurality of fan blade-shaped spokes which are distributed in a circumferential direction, the framework disc is used for being installed on a side close to an airflow incoming direction, and the fan blade disc is used for being installed on a side away from the airflow incoming direction. According to the combined lampblack intercepting net disc, the framework disc is used for intercepting pollutants, cyclone generated when the fan blade disc rotates is used for separating the pollutants, and compared with a traditional framework type intercepting disc, the combined type lampblack intercepting net disc is better in filtering efficiency; meanwhile, the fan blades of the net disc have a one-way driving function on airflow; under a certain condition, the fan blade disc can partially or completely replace a fan in a system when driving airflow, and compared with a traditional silk screen type intercepting disc and a traditional plate net type intercepting disc, the framework spokes and the fan blade-shaped spokes are good in rigidity, and the advantages of a plurality of existing intercepting discs are integrated.

Description

technical field [0001] The invention relates to the technical field of industrial oil mist and commercial oil fume filtration, in particular to a composite oil fume interception network disk, a range hood and a fanless range hood. Background technique [0002] The interception plate is one of the most important structural parts in the range hood, which affects the filtration efficiency of the range hood, the maintenance cycle of the range hood, its own service life, etc. There are three common structural forms, namely: wire mesh type Intercepting plate, plate net type intercepting plate and skeleton type intercepting plate. [0003] Among them, the structure of the wire mesh interception plate is as follows: figure 1 As shown, it includes: filter mesh 1, network disk frame body 2 and positioning sleeve 3, network disk frame body 2 includes rim 17 and fixed chuck 4, rim 17 is fixedly connected to the fixed chuck by radial rib 6 On the disc 4, the included angle between the ...

Problems solved by technology

[0006] The screen-type interception disc has a small filter gap, which has a high probability of friction and collision with pollutant molecules, and the separation efficiency is moderate, but it is easy to block and has poor rigidity, and the continuous separation effect is not ideal; the plate-mesh interception disc has a moderate filter gap and a spiral spoke separation efficiency Moderate, but also easy to block and poor rigidity; these two interceptor discs are the mainstream interceptor discs on the market, accounting for nearly 90% of the current market sales

Compared with the above two types of interception discs, the skeleton type interception disc has relatively better rigidity, but the filter gap is large, the probability of friction and collision with pollutant molecules is small, and it is prone to air leakage. The separation efficiency and effect are the worst among the three structures A sort of

[0007] It can be seen that the existing three types of intercepting discs have their own advantages and disadvantages. The filtering effect is better but the stiffness is poor, and the stiffness is better but the filtering effect is not good. How to integrate the advantages of the existing intercepting discs so that the stiffness of the intercepting disc is good while ensuring Filtering effect has become a technical problem to be solved urgently
