Problems solved by technology

However, there are still problems in the use of this purifier: First, the electrostatic treatment belongs to post-purification. Before the oil fume enters the purifier, a large amount of oil fume will stay in the flue, and the flue cannot be cleaned. If things go on like this, the flue will be blocked. Cause fire hazards; second, the electrostatic equipment works well when it i

Example Embodiment

[0028] Example

[0029] Such as Figure 1 to 5 As shown, taking the household range hood as an example, the fan dynamic range hood installed on the turbo fan of the household range hood includes a protective cover body, which is in the shape of a truncated cone, the bottom of which is a large round surface, and the side wall is a cone The air outlet formed by the top opening is used to install on the blade keel of the fan and the bottom fan of the household range hood. At this time, the bottom of the protective cover body is located directly above the stove, at the bottom of the protective cover body The air inlet is formed with uniformly arranged micro-holes and the side wall; in this embodiment, the protective cover body adopts a split structure, including a side wall plate body 2, and a bottom circular plate 3, the side wall plate body 2 and the bottom circular plate The dihedral angle between the plates 3 is 45°. Depending on the model, the included angle can be appropriatel...

Abstract

A dynamic oil smoke protective cover for a draught fan is disclosed. The protective cover comprises a protective cover main body having a circular truncated cone shape. The bottom and the side wall of the protective cover main body are in plate structures. The top of the protective cover main body is opened to form a wind outlet. The bottom and the side wall of the protective cover main body are respectively provided with evenly arranged micro holes. The protective cover overcomes the oil smoke pollution problem that is not liable to control and caused by separation of pumping drainage and treatment of range hoods at present, protects impellers and motors of the draught fan from being contaminated by oil smoke, and largely prolongs the maintenance period and service lifetime of the draught fan. Pre-purification is adopted, and is matched with a self-cleaning device, and therefore oil smoke particles can be removed efficiently for a long term, oil smoke is prevented from entering the draught fan and a pipeline, and problems frequently caused by oil smoke tail purification devices, namely fire hazards caused by long-term oil accumulation in oil smoke pipelines, secondary pollution in an oil smoke discharging process, and oil dropping and leakage in an oil smoke discharging port, can be effectively overcome.

Description

technical field [0001] The invention relates to the field of dynamic oil fume purification of a turbo fan used in kitchens, in particular to a dynamic oil fume protective cover for a fan. Background technique [0002] The electrostatic fume purifier is mainly used for the purification of kitchen fume. It has the characteristics of high purification efficiency, low noise and safety during equipment operation. Electrostatic fume purifiers are mainly used for the purification and treatment of kitchen fumes in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places; food frying and cooking processing industries; oil splash heat treatment workshops, oil mist lubrication workshops, workpieces Industrial occasions such as welding workshops and olefin oil boiler emissions. The oil fume is sucked into the electrostatic oil fume purifier by the fan, and some of the larger oil mist droplets and oil dirt particles are trapped on the equalizer p...
