Description

Muffler protective cover

Technical Field

The utility model relates to a protection casing especially relates to a muffler protection casing.

Background

The muffler protection cover is installed outside the muffler and used for guiding gas ejected by the muffler. The gas temperature that engineering vehicles such as loader's muffler jetted is high, the velocity of flow is fast, and under heat-conducting effect, thereby the protection casing can be influenced the life of protection casing and have certain potential safety hazard by the heating of the high temperature gas who jets. In view of this, there is a need for improvements to existing muffler boot structures.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the not enough of existence among the prior art for the high-temperature gas who spouts in the muffler protection casing can rapid cooling, the utility model provides a muffler protection casing.

The technical scheme is as follows: in order to achieve the above object, the utility model discloses a muffler protection casing, include:

the device comprises a shell, a first flow channel and a second flow channel, wherein a flow channel is formed in the shell, and an inlet and an outlet are respectively formed in two ends of the flow channel;

the partition plate is connected to the inside of the flow channel and divides the flow channel into a first cavity and a second cavity which are adjacent up and down; and one end of the partition plate, which is close to the outlet, is provided with a through hole, and the first chamber is communicated with the second chamber through the through hole.

Preferably, the partition plate is detachably connected in the flow passage.

Preferably, the inner wall of the runner is provided with a slideway, and the edges of the two sides of the partition board extend into the slideway to form sliding connection with the shell.

Preferably, the flow passage has a volume gradually decreasing from the inlet to the outlet.

Preferably, the inlet of the flow passage is provided with an orifice groove for connection with an external member.

Preferably, the outlet of the flow channel is provided with a baffle.

Preferably, the inlet of the flow channel faces in a first direction and the outlet of the flow channel faces in a second direction.

The utility model discloses a muffler protection casing has following beneficial effect at least: the baffle is connected in the shell of muffler protection casing, and the baffle separates the runner in the shell and forms first cavity and second cavity, the second cavity is used for the water conservancy diversion by the high-temperature gas that the muffler erupted, and the high-temperature gas velocity of flow makes the pressure in the second cavity reduce rapidly, because first cavity and second cavity pass through the perforating hole intercommunication, so the pressure of first cavity also descends fast, and outside air is introduced first cavity under the effect of atmospheric pressure, and the first cavity absorbs the heat of second cavity and makes the temperature of high-temperature gas descend rapidly, has prolonged the life of muffler protection casing.

Detailed Description

The principles and features of the present invention will be described with reference to fig. 1 to 7, which are provided for illustration only and are not intended to limit the scope of the present invention.

A muffler protecting cover comprises a shell 1 and a partition plate 5.

The shell 1 is an integrally formed thin-walled part. A flow channel 2 is formed in the housing 1, an inlet 3 and an outlet 4 are respectively arranged at two ends of the flow channel 2, and the volume of the flow channel 2 from the inlet 3 to the outlet 4 is gradually reduced. Referring to fig. 1, wherein the inlet 3 is oriented in a first direction, the X-direction; with its outlet 4 facing in a second direction, the Y-direction. The inlet 3 of the flow passage 2 is provided with a hole 10 connected to an external member, which is a body of a loading vehicle or the like. And a plurality of guide plates 11 are arranged at the outlet 4.

The baffle plate 5 is arranged in the flow channel 2, the baffle plate 5 divides the flow channel 2 into a first chamber 6 and a second chamber 7, the first chamber 6 is arranged above the second chamber 7, and the volume of the first chamber 6 is smaller than that of the second chamber 7. The partition plate 5 is provided with a through hole 8 at one end close to the outlet 4 of the flow channel 2, and the through hole 8 communicates the first chamber 6 with the second chamber 7. The partition board 5 is detachably connected in the flow channel 2, specifically, two slide ways 9 are arranged on the side walls of the flow channel 2, and two side edges of the partition board 5 extend into the slide ways 9 to form a sliding connection between the partition board 5 and the housing 1. The first chamber 6 is used for guiding air, and the second chamber 7 is used for guiding high-temperature gas ejected by the silencer.

The cooling principle of this muffler protection casing does: the high-temperature gas ejected by the silencer has high flow rate, the pressure of the second chamber 7 is reduced rapidly after entering the second chamber 7, the first chamber 6 is communicated with the second chamber 7, the pressure of the first chamber 6 is reduced due to the pressure reduction of the second chamber 7, the pressure in the first chamber 6 is smaller than the external atmospheric pressure, and the external air enters the first chamber 6 and is subjected to heat exchange with the high-temperature gas in the second chamber 7, so that the high-temperature gas in the second chamber 7 is reduced rapidly.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
