Abstract
The utility model relates to an acid and alkali-resistant draught fan device, which belongs to the field of the draught device, and comprises a smoke exhausting fan and a smoke exhausting pipe which is matched with the smoke exhausting fan, and is characterized in that a smoke collecting pipe which presents in a T shape with the smoke exhausting pipe is arranged below the smoke exhausting pipe, and the smoke exhausting fan is arranged at the end part of the transverse exhausting pipe, and the other end of the smoke exhausting pipe and the end part of the smoke collecting pipe present in an opened structure. After improving the prior art, by adopting the externally-built structure of the exhaust fan and adopting the T-structure exhausting pipe, the acid and alkali-resistant draught fan device has the advantages that the structure is simple, and each part is prevented from being corroded by the gas, and the service life of the device is long.
Description
Technical field
The utility model belongs to pump drainage cigarette device field, specifically is a kind of acid and alkali-resistance pump drainage cigarette blower fan apparatus.
Background technology
Laboratory in each enterprise, all standard configuration has special-purpose jet absorption type air-introduced machine, and to remove the various waste gas that the laboratory produces when doing chemical examination, safeguard work personnel's is healthy and safe.The various special-purpose jet absorption type air-introduced machine device of prior art, its air-introduced machine assembly all is positioned at suction tube inside, not only influence the unobstructed of gas flow, and because what produce in the laboratory often is to have acidity or alkaline severe corrosive gas, therefore the jet absorption type air-introduced machine device assembly that often causes installing in the suction tube is subjected to corrosion and damage, need frequent safeguarding, simultaneously for prolonging the service life of jet absorption type air-introduced machine device assembly, each parts needs to adopt special material to make more, also increased the use cost of enterprise, for this reason, need improve similar jet absorption type air-introduced machine device, to satisfy the routine work needs in enterprise laboratory.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and prior art is improved, and provides a kind of simple in structure, stops each parts gas attack that is corroded, the acid and alkali-resistance pump drainage cigarette blower fan apparatus that service life of equipment is long.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of acid and alkali-resistance pump drainage cigarette blower fan apparatus, comprise pump drainage cigarette blower fan and the smoke extracting tube that matches, the present technique main points are that the smoke extracting tube below is provided with the smoke collection pipe that is T font structure with it, pump drainage cigarette blower fan is positioned at the smoke extracting tube end of horizontally set, and the end of the smoke extracting tube other end and smoke collection pipe is a unenclosed construction.
Described smoke extracting tube bottom is provided with section and is trumpet-shaped exhaust fume collecting hood.
In order further to improve the air-out effect of pump drainage cigarette blower fan, the center extended line of smoke extracting tube and smoke collection pipe is acuter angles.
After the utility model improves prior art, owing to adopted pump drainage cigarette blower fan outlet structure, and adopt the smoke extracting tube of T structure, therefore had simple in structurely, stopped each parts gas attack that is corroded, the advantage that service life of equipment is long.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic diagram.
The specific embodiment
As shown in Figure 1, this acid and alkali-resistance pump drainage cigarette blower fan apparatus, comprise pump drainage cigarette blower fan 1 and the smoke extracting tube 4 that matches, the present technique main points are that smoke extracting tube 4 belows are provided with the smoke collection pipe 3 that is T font structure with it, pump drainage cigarette blower fan 1 is positioned at smoke extracting tube 4 ends of horizontally set, and the end of smoke extracting tube 4 other ends and smoke collection pipe 3 is a unenclosed construction.
Described smoke extracting tube 3 bottoms are provided with section and are trumpet-shaped exhaust fume collecting hood 5.
Before use, by flange 2 pump drainage cigarette blower fan 1 and smoke extracting tube 4 are connected as one; Start pump drainage cigarette blower fan 1 during use, then pump drainage cigarette blower fan 1 rotation at a high speed, produce high velocity air, high velocity air enters smoke extracting tube 4 from pump drainage cigarette blower fan 1, the smoke collection pipe 3 that smoke extracting tube 4 belows are provided with produces suction, corrosive gas is discharged into outdoor safe location through exhaust fume collecting hood 5 and smoke collection pipe 3 backs that smoke collection pipe 3 ends are provided with by smoke extracting tube 4 ends, thereby has ensured that laboratory operation personnel's is healthy and safe.
In order further to improve the air-out effect of pump drainage cigarette blower fan 1, smoke extracting tube 4 is acuter angles with the center extended line of smoke collection pipe 3.
After the utility model improves prior art, owing to adopted pump drainage cigarette blower fan outlet structure, and adopt the smoke extracting tube of T structure, therefore had simple in structurely, stopped each parts gas attack that is corroded, the advantage that service life of equipment is long.
