Abstract
The invention discloses a structure for cooling an engine silencer. The structure comprises an engine, a front half fan volute, a rear half fan volute and an impeller. The structure is characterized in that an induced air hole is arranged on the front half fan volute near the silencer and a wind shield is arranged on an inner wall of the front half fan volute positioned on one side of the induced air hole. The structure has the advantages that high-speed air flow flowing through a positive pressure area of a fan volute is blocked through the wind shield so that the high-speed air flow blows out through the induced air hole to cool the upper half part of the silencer, a lower wind shield blocks the high-speed air flow flowing through the positive pressure area of the fan volute so as to enable the high-speed air flow to blow out through a lower induced air hole to cool the lower half part of the silencer, the silencer can be cooled rapidly, temperature of the silencer is lowered, so that temperature of the whole engine is greatly reduced, and service life of the engine is greatly prolonged.
Description
Technical field
Patent of the present invention 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 a large amount of heats 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 motor working life, take the mode of motor small fan self cooling more at present, but the effect that a lot of motor can not be satisfied the demand and in time be lowered the temperature, 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 invention is to provide 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, improve the working life of motor greatly, satisfied the requirement of low emission level engine.
The technological scheme that the present invention takes is:
A kind of structure of cooled engine baffler, comprise motor, preceding 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 preceding half volute of blower, it is characterized in that: near preceding half volute of blower the described baffler is provided with the air inducing hole, is provided with barge board at the preceding half volute of blower inwall of air inducing hole one side.
Described air inducing hole is provided with air inducing hole and following air inducing hole, and last air inducing hole is positioned near the baffler top, and following air inducing hole is positioned near the baffler bottom.
Described barge board is provided with barge board and following barge board, and described upward barge board is positioned at a side in air inducing hole, and described barge board down is positioned at a side in air inducing hole down.
Described upward air inducing hole reaches down, and the air inducing hole is a plurality of.
The invention has the beneficial effects as follows, to the flow through part high velocity air of volute of blower zone of positive pressure of last barge board blocks, make high velocity air blow out the cooling baffler first half from last air inducing hole, to the flow through part high velocity air of volute of blower zone of positive pressure of following barge board blocks, make high velocity air blow out cooling baffler Lower Half from following air inducing hole, baffler can be cooled off rapidly, and temperature is reduced, thereby reduce the motor complete machine temperature greatly, improve motor working life greatly.

Sequence number explanation in the accompanying drawing: 1, motor; 2, impeller; 3, preceding half volute of blower; 4, fastening screw trip bolt; 5, later half volute of blower; 6, go up the air inducing hole; 7, baffler; 8, following air inducing hole; 9, snail road; 10, go up barge board; 11, following barge board.
Embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, accompanying drawing 5, the present invention program is made up of motor 1 (baffler 7), preceding half volute of blower 3 (go up air inducing hole 6, following air inducing hole 8, snail road 9, go up barge board 10, following barge board 11), later half volute of blower 5, impeller 2.
Impeller 2 is placed on 9 li in the snail road that preceding half volute of blower 3 and later half volute of blower 5 be combined to form, and preceding 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.
Last air inducing hole 6, time air inducing hole 8, last barge board 10, following barge board 11 are all on preceding half volute of blower 3, last air inducing hole 6, following air inducing hole 8 are a plurality of, last air inducing hole 6 is positioned at the position that is close with baffler 7 upper half part on preceding half volute of blower 3, and following air inducing hole 8 is positioned at the position that is close with baffler 7 lower half portions on preceding half volute of blower 3.Last barge board 10 is positioned on the inwall of preceding half volute of blower 3, and is positioned at the below in air inducing hole 6, and following barge board 11 is positioned on the inwall of preceding half volute of blower 3, and is positioned at the below in air inducing hole 8 down.
1 impeller 2 of piloting engine is rotated at a high speed in the snail road 9 of preceding half volute of blower 3 and 5 formation of later half volute of blower and is produced high velocity air, high velocity air flows along certain direction in the snail road, when high velocity air is flowed through when going up barge board 10 by last air inducing hole 6, last barge board 10 stop portions high velocity airs make it through last air inducing hole 6 and spray the upper half part that blows to baffler 7; When high velocity air was flowed through down barge board 11 by following air inducing hole 8, following barge board 11 stop portions high velocity airs made it to blow to through 8 ejections of following air inducing hole lower half portion of baffler 7, cool off baffler 7 rapidly.
The invention has the beneficial effects as follows, 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 last 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 following barge board blocks and makes it to blow out cooling baffler Lower Half through air inducing hole down, baffler can be cooled off rapidly, temperature is reduced, thereby reduce the motor complete machine temperature greatly, improve the working life of motor greatly.
