Energy-saving auxiliary cooling device of concrete milling machine

Abstract

The invention discloses an energy-saving auxiliary cooling device of a concrete milling machine. The energy-saving auxiliary cooling device of the concrete milling machine comprises a fuel oil tank, an engine and a water tank. The bottom of the fuel oil tank is provided with an oil suction opening. The top of the fuel oil tank is provided with an oil return opening. One side of the engine is connected with the oil suction opening through an oil suction pipeline, and the other side of the engine is connected with the oil return opening through an oil return pipeline. The oil return pipeline is partially arranged in the water tank. A cooling water pipe is arranged in the engine. One end of the cooling water pipe is connected with the bottom of the water tank through a water inlet pipe. The other end of the cooling water pipe is connected with the water pump through a water drawing pipeline. A water outlet of the water pump is connected with a water outlet pipeline. The water outlet pipeline is connected with a heat dissipation tank. A sprayer is installed at a pipe opening of the water outlet pipeline. A cooling box is located over the water tank. A draught fan is arranged on the top of the cooling box. The bottom of the cooling box is provided with a circulation opening. The circulation opening is connected with the water tank through a circulation pipeline. The energy-saving auxiliary cooling device of the concrete milling machine can fully utilize existing resources and achieves more complete cooling, so that cooling of the energy-saving concrete milling machine is more efficient, and energy is also saved.

Description

technical field [0001] The invention relates to the technical field of milling machines, in particular to an auxiliary cooling device for a concrete energy-saving milling machine. Background technique [0002] Milling machine is one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, and freight yards. It can also be used to remove road congestion, oil waves, and texture. It can also be used to excavate pits and grooves on the road surface, as well as roughen the cement pavement and mill the surface layer. Traditional milling machine cooling usually uses radiators to dissipate heat and add cooling water pipes to the engine to reduce the temperature of the engine and fuel. [0003] However, this heat dissipation method has the following problems. First, in summer or after the milling machine works for a long time, the heat ...

Problems solved by technology

[0003] However, this heat dissipation method has the following problems. First, in summer or after the milling machine works for a long time, the heat dissipation for the engine alone is not enough to achieve the cooling target, which reduces the working efficiency of the milling machine and increases the possibility of danger. ; Second, milling machines usually come with a large sprinkler tank, and the traditional heat dissipation method does not make use of this existing resource, resulting in a waste of resources
