Abstract
The utility model discloses a structure for cooling an engine muffler. The structure comprises an engine, a front half fan volute, a rear half fan volute and impellers, and is characterized in that an air guiding hole is formed in the portion, close to a muffler body, of the front half fan volute, and wind shields are arranged on the inner wall, on one side of the air guiding hole, of the front half fan volute. The structure for cooling the engine muffler has the advantages that high-speed air flow flowing through a fan volute positive-pressure area is shielded through the upper wind shield and made to be blown out through the air guiding hole to cool the upper half portion of the muffler body, high-speed air flow flowing through the fan volute positive-pressure area is shielded through the lower wind shield and made to be blown out through the air guiding hole to cool the lower half portion of the muffler body, the muffler body can be fast cooled, the temperature can be lowered, therefore, the temperature of the whole machine of the engine can be greatly lowered, and the service life of the engine is greatly prolonged.
Description
Technical field
The utility model patent relates to technical field of engines, particularly a kind of structure of cooled engine.
Background technique
At present, contain catalyzer in China's emission regulation demands low emission level engine baffler, the a large amount of harmful components that when catalyzer is fissioned, thereby full combustion of fuel reduced greatly to contain in the tail gas, alleviated the pollution of atmosphere, yet, can produce amount of heat during burning causes baffler and even motor complete machine temperature too high, if untimely cooling, the core component wearing and tearing are very fast, thereby seriously reduce service life of aeroengine, take the mode of motor small fan cooling itself more at present, the in time effect of cooling but a lot of motor can not be satisfied the demand, therefore, be badly in need of the structure of the quick cooled engine baffler of a kind of energy.
Summary of the invention
The purpose of this utility model provides a kind of structure of cooling off the low emission level engine baffler, this kind motor is installed in knapsack sprayer-duster, wind-driven cleaning machine etc. and utilizes on the portable machine of blower fan work, the high velocity air that utilization is drawn from the zone of positive pressure of volute of blower cools off baffler, this structure can reduce the temperature of baffler quickly and effectively, greatly improve the working life of motor, satisfied the requirement of low emission level engine.
The technological scheme that the utility model is taked is:
A kind of structure of cooled engine baffler, comprise motor, first half volute of blower, later half volute of blower, impeller, described motor is provided with baffler, described impeller is placed in the snail road of forward and backward half volute of blower formation, motor is connected with impeller, motor is positioned at a side of first half volute of blower, it is characterized in that: near the first half volute of blower the described baffler is provided with the air inducing hole, is provided with barge board at the first half volute of blower inwall of air inducing hole one side.
Described air inducing hole is provided with air inducing hole and lower air inducing hole, and upper air inducing hole is positioned near the baffler top, and lower air inducing hole is positioned near the baffler bottom.
Described barge board is provided with barge board and lower barge board, and described upper barge board is positioned at a side in air inducing hole, and described lower barge board is positioned at a side in lower air inducing hole.
Described upper air inducing hole and lower air inducing hole are a plurality of.
The beneficial effects of the utility model are, to the flow through part high velocity air of volute of blower zone of positive pressure of upper barge board blocks, make high velocity air blow out the cooling baffler first half from upper air inducing hole, to the flow through part high velocity air of volute of blower zone of positive pressure of lower barge board blocks, make high velocity air blow out cooling baffler Lower Half from lower air inducing hole, baffler can be cooled off rapidly, and temperature is reduced, thereby greatly reduce the motor complete machine temperature, improve greatly service life of aeroengine.

Sequence number explanation in the accompanying drawing: 1, motor; 2, impeller; 3, first half volute of blower; 4, fastening screw trip bolt; 5, later half volute of blower; 6, upper air inducing hole; 7, baffler; 8, lower air inducing hole; 9, snail road; 10, upper barge board; 11, lower barge board.
Embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, accompanying drawing 5, the utility model scheme is comprised of motor 1 (baffler 7), first half volute of blower 3 (upper air inducing hole 6, lower air inducing hole 8, snail road 9, upper barge board 10, lower barge board 11), later half volute of blower 5, impeller 2.
Impeller 2 is placed on 9 li in the snail road that first half volute of blower 3 and later half volute of blower 5 be combined to form, and first half volute of blower 3 and later half volute of blower 5 connect by fastening screw trip bolt 4, and impeller 2 is connected with motor 1.
Upper air inducing hole 6, lower air inducing hole 8, upper barge board 10, lower barge board 11 are all on first half volute of blower 3, upper air inducing hole 6, lower air inducing hole 8 are a plurality of, upper air inducing hole 6 is positioned at the position that is close with baffler 7 upper half part on the first half volute of blower 3, and lower air inducing hole 8 is positioned at the position that is close with baffler 7 lower half portions on the first half volute of blower 3.Upper barge board 10 is positioned on the inwall of first half volute of blower 3, and is positioned at the below in air inducing hole 6, and lower barge board 11 is positioned on the inwall of first half volute of blower 3, and is positioned at the below in lower air inducing hole 8.
1 impeller 2 of piloting engine produces high velocity airs at the snail road of first half volute of blower 3 and 5 formation of later half volute of blower 9 interior High Rotation Speeds, high velocity air flows along certain direction in the snail road, when high velocity air was flowed through upper barge board 10 by upper air inducing hole 6, upper barge board 10 stop portions high velocity airs made it through upper air inducing hole upper half part that 6 ejections blow to baffler 7; When high velocity air was flowed through lower barge board 11 by lower air inducing hole 8, lower barge board 11 stop portions high velocity airs made it through lower air inducing hole lower half portion that 8 ejections blow to baffler 7, cool off rapidly baffler 7.
The beneficial effects of the utility model are, to the flow through high velocity air of volute of blower zone of positive pressure of barge board blocks and makes it to blow out through upper air inducing hole the cooling baffler first half on the process, to the flow through high velocity air of volute of blower zone of positive pressure of lower barge board blocks and makes it to blow out through lower air inducing hole cooling baffler Lower Half, baffler can be cooled off rapidly, temperature is reduced, thereby greatly reduce the motor complete machine temperature, improve greatly the working life of motor.
