Venturi exhaust air adapter device for purifying oil fume and manufacturing method thereof

Abstract

A Venturi exhaust air transfer device for purifying oil fume and a manufacturing method thereof belong to the technical field of machining. All parts are processed by casting molding, the manufacturing method is scientific and reasonable, and the manufacturing speed is fast. Compared with traditional milling, it can not only save processing materials, but also realize large-scale processing in the same process, reducing manufacturing costs. The components in the device are easy to assemble and disassemble quickly. The air inlet, throat and air outlet in the main structure of the device form a Venturi effect structure. The air speed of the air outlet is greater than the air speed of the air inlet, and negative pressure is generated through the venturi throat, and the fume is generated. Under the condition that the power of the machine suction motor is constant, the suction force of the oil fume is increased, and the energy saving effect is improved. In addition, the setting of the activated carbon cake further achieves the purpose of protecting the environment.

Description

technical field [0001] The invention belongs to the technical field of machining, and relates to an exhaust air adapter device and a manufacturing method thereof, in particular to a Venturi exhaust air adapter device for purifying lampblack and a manufacturing method thereof. Background technique [0002] At present, people are paying more and more attention to environmental protection, and the requirements for environmental protection standards for various emissions are becoming more and more stringent, especially for smoke and dust emissions, ranging from factory chimneys to car exhaust, as well as various restaurants in the food street. The fume produced has special purification equipment, but the range hood used by thousands of households directly discharges the air with fume into the atmosphere, causing great damage to the environment. The current exhaust device of the range hood has the following defects : (1) The suction force generated by the exhaust air is completel...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the existing defects in the structure of the exhaust device of the range hood that the oil fume cannot be filtered and the energy-saving effect is poor. It is necessary to improve the exhaust device. However, it is prone to disadvantages such as difficult processing, low processing efficiency, and high manufacturing cost. A venturi exhaust adapter device for purifying oil fume and its manufacturing method are proposed. The parts processed by this manufacturing method are easy to quickly assemble and disassemble. , can improve manufacturing efficiency and reduce processing costs, and can also improve the working efficiency of range hoods, and further achieve the purpose of saving energy and protecting the environment
