Dust and explosion prevention fan for chemical plant

Abstract

The invention provides a dust and explosion prevention fan for a chemical plant. The dust and explosion prevention fan comprises a fan shell, an explosion prevention motor, a rotating shaft, fan blades, an opening, an explosion prevention partition plate, a supporting column, a horn mouth, an explosion prevention layer, a front filter net and a rear filter net. The dust and explosion prevention fan is characterized in that the explosion prevention layer is arranged on the inner wall of the fan shell, the rear filter net is arranged inside the fan shell, one end of the fan shell is connected with the horn mouth, the front filter net is arranged inside the horn mouth, the explosion prevention partition plate is arranged between the fan shell and the horn mouth, the explosion motor is fixedly connected with the rotating shaft, and the rotating shaft is connected with the fan blades through the opening. The dust and explosion prevention fan is simple in structure and easy to install; due to the arrangement of the explosion prevention layer, damage caused by explosion of the motor is avoided, and potential safety hazards are eliminated; due to the arrangement of the explosion prevention partition plate, damage, caused by splashing of explosives of the motor, to the human body can be prevented; and due to the arrangement of the front and rear filter nets, dust, sundries and the like can be prevented from entering the fan, and normal working of the fan is prevented from being affected.

Description

Technical field [0001] The invention relates to an explosion-proof fan, in particular to a dust-proof and explosion-proof fan for a chemical plant, belonging to the technical field of fan equipment. Background technique [0002] Existing ventilator is a kind of mechanical equipment for ventilation, which is used in chemical plants. At present, the ventilators used in the market generally have the motor outside and are exposed to the surrounding environment to directly contact the surrounding gas. For chemical plants containing chemical products and chemical waste gas, the ventilation requirements of the chemical plants are very high. It is driven by a motor, and sparks are easily generated during the rotation of the motor. If the ventilator is directly placed in an environment containing oil and gas or flammable and explosive gas, it is prone to explosion; therefore, the industry urgently needs an explosion-proof ventilator. Summary of the invention [0003] The technical problem...

Problems solved by technology

At present, the ventilators used in the market generally have motors on the outside, exposed to the surrounding environment and in direct contact with the surrounding gas, and for chemical plants containing chemical products and chemical waste gases, the ventilation requirements for chemical plants are very high. Ventilators It is driven by a motor, and the motor is prone to sparks during rotation. If the ventilator is directly placed in an environment containing oil, gas or flammable and explosive gases, it will easily explode; so an explosion-proof ventilator is urgently needed in the industry
