Abstract

The utility model relates to an axial hot fan arranged in the hot air transport passage of a drying room. The utility model is structurally characterized in that the fan is composed of a transmission system, a heat shielding barrel and a rectification body. A motor on the exterior of the barrel body can drive a belt wheel on one end of a shaft to make transmission by a belt, and the other end is provided with an impeller. The front side of the impeller is provided with the rectification body fixed to the barrel body, and the heat shielding barrel is connected with the screw bolt of a lapping plate by a heat shielding barrel cover. The lapping plate is fixedly connected with the heat shielding circular barrel, and the interior of the barrel is longitudinally fixedly provided with a cold air guide plate. The fan utilizes the ambient natural cold air to reduce the heat quantity generated by the bearing running and improve static pressure efficiency of the fan and the dynamic balancing performance of the impeller. The utility model is convenient for maintenance.

Description

Axial hot fan for drying room
The utility model belongs in the building material industry to the device of drying room heat air delivery, and specifically a kind of drying room axial flow is sent air heater.
Blower fan to adobe, unbaked tile and ceramic blank drying chamber heat air delivery is generally centrifugal fan at present, and the hot blast of conveying is generally using residual heat from kiln furnace, and temperature is about 250 ℃.The fan bearing of working under this environment does not generally have cooling method.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide a kind of can with natural cold wind cooling bearing, wheel rotation stably drying room axial flow send air heater.
The purpose of this utility model can reach by following measure:
Drying room axial flow send air heater to be made up of blower fan cylindrical shell and tube inner driver and rectification body, characteristics are that the outer motor of cylindrical shell drives the belt pulley rotation of installing on the end of axle through belt, the end in addition of axle is installed impeller, and the rectification body that is fixed on the cylindrical shell is installed before the impeller.The structure of heat insulation tube is that lapping plate and heat insulation cylinder are fixedly connected, and vertically are fixed with the cold wind guide plate in the tube by heat insulation tube cover and lapping plate Bolt Connection.The structure of rectification body is cowling and dunnage welding, and the end in addition of dunnage is connected by the connecting plate bolt with the blower fan cylindrical shell.

Fig. 1 is the utility model structural front view.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is heat insulation barrel structure plan view.
Fig. 4 is the left view of Fig. 3.
Fig. 5 is the plan view of Fig. 3.
Fig. 6 is the rectification body structural front view.
Fig. 7 is the left view of Fig. 6.
Among the figure: 1-rectification body, 2-blower fan cylindrical shell, 3-impeller, 4-axle, the 5-bearing support, 6-belt pulley, the heat insulation tube of 7-, 8-bearing bracket, the 9-belt, 10-belt housing, 11-motor, the heat insulation cylinder of 12-, 13-bolt, the heat insulation tube cover of 14-, the 15-lapping plate, 16-cold wind guide plate, 17-connecting plate, the 18-cowling, 19-dunnage, 20-bolt.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
As shown in Figures 1 and 2, drying room axial flow send air heater to be made up of transmission device, heat insulation tube and rectification body three parts, the belt 9 of motor 11 in belt housing 10 drives the belt pulley 6 that is installed on the axle 4 and rotates, axle 4 is by 5 supportings of two bearing supports, bearing support 5 usefulness bolt are on bearing bracket 8, and bearing bracket 8 is welded into one with blower fan cylindrical shell 2.Impeller 3 usefulness keys 4 connect with axle, by baffle plate and bolt to its axially locating.Belt pulley 6 usefulness keys connect with axle 4, heat insulation tube 7 and bearing bracket 8 welding.Heat insulation tube cover 14 usefulness bolts 13 are connected on the lapping plate 15 shown in accompanying drawing 3, accompanying drawing 4, the accompanying drawing 5, lapping plate 15 and heat insulation cylinder 12 welding, and natural cold wind guide plate 16 vertical weldings are connected on the heat insulation cylinder 12, and belt housing 10 is welding with heat insulation cylinder 12.Rectification body 1 shown in accompanying drawing 6 and the accompanying drawing 7 connects by connecting plate 17 usefulness bolts 20 with blower fan cylindrical shell 2.Connecting plate 17 and 2 welding of blower fan cylindrical shell, three dunnages 19 are welded on the cowling 18.This connecting mode is convenient to the installation and removal of fan bearing, also is convenient to the vibration when reducing wheel rotation to the bearing make-up oil.
Working procedure of the present utility model is:
Driving the belt pulley 6 that is installed on the axle 4 by motor 11 by belt 9 rotates, thereby make constantly rotation heat air delivery of impeller 3, also nature cold wind is brought into along belt housing 10 in the heat insulation tube 7 continuously through heat insulation cold wind inlet shown in the accompanying drawing 5 simultaneously, be welded on the water conservancy diversion that flows to of the interior 16 pairs of cold wind of natural cold wind guide plate of heat insulation tube, nature cold wind is flowed around the bearing support, and the heat that produces when in time taking away bearing operation.
The utility model compared with prior art has following advantage:
The heat that produces when 1, the extraneous natural cold wind of axial hot fan for drying room utilization reduces bearing operation has prolonged service life of bearing.
2, rectification body and gripper shoe welding, gripper shoe are connected installing/dismounting and grease-added the lubricating of being convenient to fan bearing with blower fan cylindrical shell bolt, and can improve the static pressure efficiency of blower fan.
3, the utility model is simple in structure, and is easy to utilize.
