Abstract
The utility model discloses a special fan used for conveying powder combustion material. The special fan comprises a bracket, a motor fixedly arranged on the bracket, a bearing block connected with the motor through belt drive, an impeller fixedly connected with the output shaft of the bearing block, and an enclosure with an air inlet and an air outlet, wherein the impeller is arranged in the enclosure, the air inlet is arranged on the same side as the connection part of the impeller and the output shaft of the bearing block, when the special fan is applied to a powder combustion material combustion system, the powder combustion material is prevented from leaking to cause environmental pollution, and the problem that when an existing fan is applied to the combustion system, the powder combustion material leaks from the connection part of the enclosure and the output shaft of the bearing block is solved.
Description
Technical field
The utility model belongs to the blower fan technical field, is specifically related to a kind of blower fan that is specifically designed to the powdery incendiary material.
Background technology
Existing blower fan generally comprises support, is fixed on the motor on support, the bearing seat be connected by belt-driving with motor, the impeller be connected with the bearing seat output shaft and the casing with ventilation inlet and air outlet that is built-in with this impeller.Yet because its ventilation inlet of existing blower fan is arranged on the opposite face of bearing seat output shaft and casing coupling end, in the time of having blower fan now and be applied to Powdered incendiary material combustion systems, above-mentioned Powdered incendiary material can be from the connecting portion seepage of bearing seat output shaft and casing, and the outside seepages of Powdered incendiary material such as a large amount of coal dusts or petroleum coke powder cause very large pollution to environment, therefore be necessary existing blower fan is carried out to improvement design, to be applicable to Powdered incendiary material combustion systems, solve the problem of Powdered incendiary material seepage.
Summary of the invention
For the deficiencies in the prior art, the utility model aims to provide applicable to Powdered incendiary material combustion systems, avoids Powdered incendiary material to cause the blower fan of environmental pollution from casing and bearing seat output shaft connecting portion seepage.
For achieving the above object, the utility model adopts following technical scheme:
A kind of blower fan that is specifically designed to Powdered incendiary material conveying, comprise support, be fixed on the motor on support, the bearing seat be connected by belt-driving with motor, the impeller be fixedly connected with the bearing seat output shaft and be built-in with the casing with ventilation inlet and air outlet of above-mentioned impeller, described ventilation inlet is arranged on impeller and the same side direction of bearing seat output shaft connecting portion.
The utlity model has following beneficial effect:
A kind of blower fan that is specifically designed to Powdered incendiary material conveying of the utility model, its ventilation inlet is arranged on casing and bearing seat output shaft connecting portion homonymy, while being applied to Powdered incendiary material combustion systems, can avoid Powdered incendiary material seepage to cause environmental pollution, when having solved existing blower fan and being applied to above-mentioned combustion systems, Powdered incendiary material is from the problem of casing and bearing seat output shaft connecting portion seepage.
The accompanying drawing explanation
Fig. 1 is a kind of right elevation that is specifically designed to the blower fan of Powdered incendiary material conveying of the utility model;
Fig. 2 is a kind of A-A face cutaway view that is specifically designed to the blower fan right elevation of Powdered incendiary material conveying of the utility model.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the claimed technological thought of the utility model so that clearer.
As shown in Figure 1-2, the present embodiment blower fan comprises a support 1, motor 20, bearing seat 21, casing 3 and the impeller 4 be built in this casing 3, and wherein motor 20 is fixed on support 1, and its output shaft end connects a belt pulley; Bearing seat 21 also is fixed on support 1, and its input shaft end connects another belt pulley, and is in transmission connection by the belt pulley on belt and motor 20.Bearing seat 21 output shafts are connected and fixed impeller 4, are provided with ventilation inlet 30 and air outlet 31 on this casing 3, and wherein ventilation inlet 30 is arranged on the homonymy of impeller 4 and bearing seat 21 output shaft connecting portions 32, and air outlet 31 is arranged on casing 3 belows.
When the present embodiment blower fan is applied to Powdered incendiary material combustion systems, Powdered incendiary material can be from impeller 4 and bearing seat 21 output shaft connecting portion 32 seepages, thereby avoid the Powdered incendiary material contaminated environment such as coal dust or petroleum coke powder.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection domain of the utility model claim within.
