Abstract
The utility model relates to a dust-explosion-preventing wet film humidifier. The dust-explosion-preventing wet film humidifier is of a vertical cabinet type structure and is composed of a cabinet body, a panel, power lines, a wet film, a water tank, a circulating water pump, a water pipe, a blower and an electrical control box, wherein the power line, the wet film, the water tank, the circulating water pump, the water pipe, the blower and the electrical control box are sequentially arranged in the cabinet body, clearances ic at joint positions between the blower and a top cover of the circulating water pump and between the blower and a bottom cover of the circulating water pump are both less than 0.2mm, sealing rings are additionally arranged at line incoming positions of the power linse of the blower and the circulating water pump, a dust-explosion-preventing control box is adopted as the electrical control box, the dust-explosion-preventing control box is internally provided with a control main board of the humidifier and a safety grid plate, and a control circuit board on the panel is sealed by the adoption of 703 silicon rubber. The dust-explosion-preventing wet film humidifier disclosed by the utility model has a high safety performance, can be used for an industrial building with explosive dust, and can play roles in effective purification and protection in order to improve the environment and remove potential explosion hazards.
Description
Technical field
The utility model belongs to the humidifier technical field, is a kind of dust explosion protection wet-film humidifying machine that is applicable in the explosive dust atmosphere.
Background technology
In technique known, normally used humidifier, because of the blower fan in the machine, water circulating pump poor sealing performance, the dynamo-electric spark that produces during running has lights the danger of explosive dust on every side.Secondly, the electrical equipment of humidifier because of its inside to explosive dust short of reliable safeguard procedures, its control mainboard might produce electric spark when humidifier turns round, and then causes the danger of extraneous explosion easily.Therefore, there is potential safety hazard in common unguarded humidifier, and because of not meeting the hazardous area that requirement of explosion proof can not be used to exist explosive dust.
The utility model content
The purpose of the utility model provides a kind of dust explosion protection wet-film humidifying machine that can use in the dust explosion risk place.
The technical scheme that the purpose of realization the utility model is taked is: this wet-film humidifying machine adopts cabinet-type structure; Form by cabinet, panel and the power line, wet film, water tank, water circulating pump, water pipe, blower fan and the electric control box that are installed in successively in the cabinet; It is characterized in that: the gap of the top cover of said blower fan and water circulating pump and its bottom joint is ic＜0.2 mm; Point of incoming cables at the power line of blower fan and water circulating pump adds sealing ring, and electric control box adopts the dust explosion protection control cabinet, and the control mainboard of humidifier is installed in the dust explosion protection control cabinet; And adding safe screen, the control circuit board in the panel adopts 703 silicone rubber seals.
Cable entry on the said dust explosion protection control cabinet adopts INCREASEDSAFETY anti-explosion cable introducing device.
The dust explosion protection wet-film humidifying machine of processing according to such scheme; Through the explosion precaution that each parts of body are set up; Can prevent effectively that electric spark from producing, avoid occurring the danger of explosive dust on every side, widen the scope of application of humidifier thus; It can be used in the dust explosion risk place, and safe and reliable.This machine is specially adapted to exist the industrial building of explosive dust, all can play purification and protective action effectively to improving environment with the elimination hidden peril of explosion.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2; The dust explosion protection wet-film humidifying machine of the utility model adopts the cabinet-type structure, is made up of cabinet 1, panel 4 and the power line 3, wet film 6, water tank 7, water circulating pump 8, water pipe 9, blower fan 10 and the electric control box 13 that are successively set in the cabinet; Wherein, The top cover of blower fan 10 and water circulating pump 8 is ic＜0.2 mm with the gap of its bottom joint, adds sealing ring 14 (Fig. 2) in the point of incoming cables of the power line 3 of blower fan 10 and water circulating pump 8, in order to improve the shell protection grade of blower fan 10 and water circulating pump 8; Make its requirement that meets dust explosion protection, and can be used in explosive dust atmosphere.What electric control box 13 adopted is the dust explosion protection control cabinet, and the control mainboard 11 of humidifier is installed in the dust explosion protection control cabinet, and adds safe screen 12, in order to prevent the generation of electric spark; Cable entry 2 on the dust explosion protection control cabinet adopts INCREASEDSAFETY anti-explosion cable introducing device, can be used for explosive dust atmosphere, and INCREASEDSAFETY anti-explosion cable introducing device can directly be purchased on market, and its structure is not being given unnecessary details.Adopt 703 silicon rubber with electronic component encapsulation on the control circuit board 5 in the panel 4, can prevent the generation of electric spark, reach the intrinsic safe explosion-proof treatment requirement, to improve security.
