Description

A device for removing exhaust gases from an internal combustion engine.

The invention relates to a ventilation technique used in closed production rooms where mobile devices with internal combustion engines / internal combustion engines / perform technical operations.

A device is known for removing exhaust gases from internal combustion engines, comprising a gas exhaust duct with a locking member arranged therein, in communication with an exhaust pipe, and also a retractable carriage mounted on rails, / A.C. USSR No. 1314207 A1; F 24 F 13/08, 1985, /. However, it does not provide for the removal of exhaust gases from mobile devices in the room, as It is used only in stationary conditions during bench tests of internal combustion engines.

The closest in technical essence is a device containing a horizontally located duct made from the bottom with a longitudinal section and closed with elastic sealing elements, which is made initially in the form of an expanded receiving part, and at the end there is a damper and a fan. In the expanded part of the duct, a gas intake carriage is inserted with the possibility of its subsequent movement. It is made of a cyclone shape and is equipped with an elliptical coupling mounted on the nozzle of the carriage, which is connected to the exhaust pipe of the engine through an intermediate pipe and is spring-loaded. /Patent. RU No. 2120040 C1 6 F01 No. 7/08; F24 F7 / 04 /. The disadvantage of this device is that when working in the premises of mobile means, they can only move in a straight line, but in most livestock buildings of a closed type during

technological operations require the movement of mobile funds throughout the area of the livestock complex.

The problem the utility model is aimed at and the technical result of its use is to maintain the optimal microclimate of closed production facilities, improve sanitary and hygienic working conditions, and extend the life of the premises and equipment.

The technical result is achieved by the fact that the device for removing exhaust gases from an internal combustion engine operating in a structure, comprising a horizontally arranged exhaust gas duct made in longitudinal section, an engine exhaust port connected to it and a gas intake carriage mounted in the duct with the possibility of longitudinal movement, is equipped with a stationary an additional exhaust gas duct fixed in the structure, installed perpendicular to the main one with the one located in it aretkoy communicating through the pipe with the main, the main gas exhaust duct is mounted on the guide rails with the possibility of transverse displacement along the additional vent duct. In addition, an exhaust fan is installed at the end of the additional exhaust gas duct.

In FIG. 1 shows a general view of the device; in FIG. 2 is a section AA in FIG. 1; in FIG. section BB in FIG. 1.

The device contains two ducts installed, perpendicular to each other, the main 1 and additional 2. The main moves along the rails 3 on the rollers 17, the additional is fixed stationary to the ceiling of the structure. On the side of the auxiliary duct 2, a longitudinal section is made, closed by elastic sealing elements 15. From the bottom of the main gas exhaust duct / duct 1, a longitudinal section is closed, closed by elastic sealing elements 15, while maintaining the tightness of the gas exhaust duct. Gas receiving carriage 5.6. installed in the air ducts, each gas intake carriage is equipped with four rollers 7. The gas intake carriage 5 located in the main duct 1 with the possibility of movement, is equipped with a pipe 8 and an ellipse-shaped coupling 9. An intermediate pipe 10 is installed under the pipe 8 of the gas intake carriage 5, connecting it to the exhaust pipe And D.V.S., and a spring 12 resting on the inner ring 13 of the intermediate pipe 10. The restrictive ring 14 is attached to the exhaust pipe 11 outside to limit and stop the intermediate pipe 10. In the additional air duct 2 there is a gas intake carriage 6. A longitudinal section is made on the side of the additional air duct 2, closed by elastic sealing elements 15. At the end of the additional air duct 2 there is a fan 16. The additional and main air ducts are connected by a pipe 8 and an elliptical sleeve 9.

The device operates as follows. Before starting work, the gas intake carriage 5 of the main duct using the intermediate pipe 10 is installed on the exhaust pipe 11 tractor, turn on fan 16.

When the tractor moves, the main duct 1 moves along with the rollers along with it, while opening the elastic sealing elements with the help of an elliptical coupling 9. Exhaust gases from DVS the tractor through the intermediate pipe 10 and the gas intake carriage 5 enter the main duct 1, then through the gas intake 6 enter the additional exhaust duct 2. When the fan is operating, a vacuum is created in the exhaust ducts, as a result of which the sealing elements 15 of both ducts are tightly connected to each other. Waste gases from D.V.S. tractors are released into the atmosphere.

The proposed device for removing exhaust gases from D.V.S. allows you to save the optimal microclimate parameters in closed production rooms during any technological operations by mobile means with DVS, which ensures the improvement of sanitary and hygienic working conditions for staff and animal welfare conditions, thereby increasing their productivity.
