Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipes, in particular to a heat-insulated exhaust pipe for a low-speed diesel engine. Background Art

[0002] Diesel engines are a commonly used power source for mechanical equipment. Their working principle is to convert the heat energy generated by fuel combustion into mechanical energy to drive the power equipment, provide it to the equipment, and then discharge the high-temperature exhaust gas generated in the conversion process from the exhaust pipe.

[0003] The exhaust gas generated by the diesel engine has a very high temperature. When it is discharged from the exhaust pipe, the temperature of the exhaust pipe will be maintained at a very high temperature due to the high-temperature exhaust gas, which can easily cause damage to the components around the exhaust system. Therefore, the exhaust pipe needs to be insulated. The existing diesel engine exhaust pipe is generally wrapped with a heat insulation cover to achieve the effect of heat insulation, but the heat insulation cover is usually tied to the exhaust pipe with Velcro. When maintaining the exhaust pipe, the heat insulation cover needs to be removed. However, after long-term repeated use, the surface fluff of the Velcro is straightened, which greatly reduces the adhesion. The Velcro is generally fixed on the heat insulation cover, so a new heat insulation cover needs to be replaced. After a long period of exhaust, the existing exhaust pipe will be blocked due to excessive carbon deposits. To clean the exhaust pipe, the exhaust pipe needs to be removed and then cleaned. The cleaning process is cumbersome and the carbon deposit cleaning efficiency is low.

[0004] Therefore, we propose a low-speed diesel engine heat-insulated exhaust pipe to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a low-speed diesel engine insulated exhaust pipe to solve the problem raised by the above background technology that the Velcro on the heat insulation cover on the current market will reduce its adhesion after long-term use, so that carbon deposits will accumulate in the exhaust pipe after replacement of the heat insulation cover and long-term exhaust, which makes cleaning cumbersome and the carbon deposit cleaning efficiency low.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-speed diesel engine insulated exhaust pipe, comprising a pipe body, an air intake interface, an exhaust interface and a heat insulation cover, the left end of the pipe body is provided with an air intake interface, and the right end of the pipe body is provided with an exhaust interface, a filter plate is provided inside the pipe body, and the pipe body is provided with an opening and closing cover, a fixing rod is fixed between the air intake interface and the exhaust interface, and the fixing rod passes through a plurality of upper clamping blocks and lower clamping blocks, and a heat insulation cover is wrapped around the surface of the pipe body.

[0007] Preferably, the filter plate is located at one end close to the air inlet interface, and the diameter of the filter plate at the filtering position is smaller than the diameter of the internal channel of the tube body.

[0008] Preferably, the opening and closing cover is located at the filter plate position, and the opening and closing cover is movably connected to the tube body, and the opening and closing cover forms a fixed structure with the tube body through a first bolt.

[0009] Preferably, the upper clamping block and the lower clamping block are movably connected via a fixing rod, and the upper clamping block and the lower clamping block form a fixing structure via a second bolt.

[0010] Preferably, the fixing rod is provided with a plurality of groups of upper clamping blocks and lower clamping blocks, and the fixing rod is provided with blocking blocks on both sides of the lower clamping blocks of each group of upper clamping blocks.

[0011] Preferably, the heat insulation cover is arranged between the tube body and the fixing rod.

[0013] (1) A filter plate is provided, and the filter plate is arranged at the air inlet position, and the exhaust gas entering the pipe body is filtered through the filter plate to avoid carbon accumulation inside the exhaust pipe after long-term use, so as to facilitate better exhaust of the exhaust pipe;

[0014] (2) An opening and closing cover is provided, and the opening and closing cover is provided at the position of the filter plate.

[0024] The filter plate 6 is located at one end close to the air inlet interface 2, and the diameter of the filtering position of the filter plate 6 is smaller than the diameter of the internal channel of the tube body 1, so that the exhaust gas can be filtered by the filter plate 6 before being discharged from the exhaust pipe, thereby avoiding the accumulation of carbon deposits inside the tube body 1.

[0025] The opening and closing cover 4 is located at the position of the filter plate 6, and the opening and closing cover 4 is movably connected to the tube body 1. The opening and closing cover 4 forms a fixed structure with the tube body 1 through the first bolt 5.

[0029] Working principle: When using the insulated exhaust pipe of a low-speed diesel engine, first connect the air intake interface 2 to the exhaust outlet of the diesel engine, then the exhaust gas generated by the diesel engine during the combustion process enters the pipe body 1 from the air intake interface 2, passes through the filter plate 6 in the pipe body 1, and is finally discharged from the exhaust interface 3, thus completing the use of the insulated exhaust pipe of the low-speed diesel engine.

[0030] When the filter plate needs to be replaced after the low-speed diesel engine insulated exhaust pipe is used for a long time for exhaust, first unscrew the first bolt 5, open the opening and closing cover 4, then take out the filter plate 6 full of carbon deposits, replace it with a new filter plate 6, close the opening and closing cover 4, and finally screw on the first bolt 5, thus completing the replacement of the filter plate of the low-speed diesel engine insulated exhaust pipe.
