Abstract
Disclosed is a separated axial-flow blower, which is composed of a casing, a bearing pedestal assembly, a quadrate pipe barrel, an impeller, a triangular belt, an electromotor and a transmission shaft, and is characterized in that: the quadrate pipe barrel is arranged in the casing, the pipe barrel is separated from a ventilation channel of the casing, the bearing pedestal assembly is arranged in the quadrate pipe barrel, the triangular belt is arranged at the upper end of the bearing pedestal assembly and is connected with the electromotor outside the pipe barrel, and the transmission shaft at the lower part of the bearing pedestal assembly is connected with the impeller; The utility model performs ventilation and exhaustion under high temperature and high humidity environment, can effectively avoid corrosion, clamping and breakage to bearings and bearing pedestals by high temperature and high humidity gas, as well as conditions of frequent burning and breaking to the triangular belt by high temperature and high humidity gas, and can reduce the breakdown rate and guarantee the safety in production.
Description
Technical field
The utility model belongs to ventilation, exhaust equipment, specifically is a kind of isolated propeller fan.
Background technique
Existing axial fan is simple in structure, and volume is little, directly connects with ventilation duct, is widely used in ventilation, air draft engineering.Improve GD30K2 (T30I) the profile shaft circulation blower fan that forms on this basis motor is contained in the air duct outside, connect transmission with the vee belt, drive is fixed on the main shaft and the impeller of air duct central authorities, has avoided carrying moist gas and being harmful to the infringement of gas to motor.But its main transmission component still are arranged on air duct inside; when carrying hot and humid gas; for example cigarette industry is dried by the fire the hot and humid gas in leaf machine, humidifier, the roasting sheet machine; this propeller fan is kept away unavoidable hot and humid gas to the corrosion of bearing, bearing support, stuck and damage; damage is frequently burnt by hot and humid gas in the vee belt simultaneously; thereby cause higher downtime rate, had a strong impact on production.
The model utility content
The utility model provides a kind of isolated propeller fan, has avoided the injury of hot and humid gas to bearing, greatly reduces shutdown maintenance number of times and time, has reduced the equipment failure outage rate.
The purpose of this utility model realizes by following technical solution:
A kind of isolated propeller fan, form by casing, bearing support assembly, rectangular socket, impeller, vee belt, motor and transmission shaft, it is characterized in that: a rectangular socket is housed in casing, the vent passages of socket and casing is kept apart, one bearing support assembly is installed in rectangular socket, bearing support assembly upper end has the outer motor of a vee belt and socket to link to each other, and the transmission shaft of bearing support assembly bottom is associated with an impeller.
Described socket rear and front end is a streamlined structure.
With isolated propeller fan described in the utility model; in hot and humid environment, ventilate, air draft; can effectively avoid hot and humid gas the corrosion of bearing, bearing support, stuck and damage and vee belt frequently to be burnt the situation of damage by hot and humid gas; reduce downtime rate, guarantee safety in production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the casing section A-A sectional drawing that the rectangular socket is installed among Fig. 1.
Each sequence number is among the figure: 1-casing, 2-bearing support assembly, the rectangular socket of 3-, 4-impeller, 5-vee belt, 6-motor, 7-transmission shaft.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1-2, a rectangular socket 3 is housed in casing 1, the vent passages of socket and casing is kept apart, bearing support assembly 2 and vee belt 3 that bearing, bearing support and belt pulley are formed are installed in the rectangular socket, make hot and humid gas logical, no longer contact bearing, bearing support, parts such as belt pulley, vee belt from rectangular socket three effluents, avoided corrosion and damage, ensured that their structural behaviour is stable and operate steadily them.Bearing support assembly upper end has the outer motor 6 of vee belt 5 and socket to link to each other, and the transmission shaft 7 of bearing support assembly bottom is associated with an impeller 4.
Because of contacting the infringement that hot and humid gas causes, can adopt stainless steel material for fear of transmission shaft 7 front ends; In order to reduce flowing resistance, can make socket 3 rear and front ends streamlined.
In order to remedy the vent area that rectangular socket reduces, the casing diameter that rectangular socket place is installed is suitably increased, make casing be the shape that shrink the rear and front end, the centre is outstanding.
Claims (2)
1. isolated propeller fan, form by casing (1), bearing support assembly (2), rectangular socket (3), impeller (4), vee belt (5), motor (6) and transmission shaft (7), it is characterized in that: a rectangular socket is housed in casing, the vent passages of socket and casing is kept apart, one bearing support assembly (2) is installed in rectangular socket (3), bearing support assembly upper end has the outer motor (6) of a vee belt (5) and socket (3) to link to each other, and the transmission shaft (7) of bearing support assembly bottom is associated with an impeller (4).
2. isolated propeller fan as claimed in claim 1 is characterized in that: socket (3) rear and front end is streamlined.
