Cold water tank for marine high-power engine cylinder head production

Abstract

The invention discloses a cold water tank for marine high-power engine cylinder head production. The cold water tank comprises a tank body, wherein a water inlet pipe is arranged in the middle of theupper end of the tank body, and a water outlet pipe is arranged on one side of the bottom of the tank body; aeration pipes are arranged at the positions, located at the bottom of the water inlet pipe,of the interior of the tank body, and each aeration pipe is provided with a plurality of equally-distributed aeration holes; an aeration fan is arranged on one side of the tank body and provided witha flow guide pipe, the aeration fan is connected with the aeration pipes through the flow guide pipe, the aeration pipes are circular-ring-shaped pipelines with gradually decreasing diameters, and every two adjacent aeration pipes communicate with each other through a connecting pipe; a connecting rod is arranged at the bottoms of the aeration pipes, a temperature inductor is arranged at the bottom of the connecting rod, the aeration pipes are arranged to be in circular ring shapes with the gradually decreasing diameters, aeration can be more uniform, the aeration efficiency is improved, andthe cooling time of backflow water is reduced.

Description

Technical field: [0001] The invention relates to the technical field of cylinder head production and processing, in particular to a cold water tank for the production of a marine high-power engine cylinder head. Background technique: [0002] The cylinder head is a component made of cast iron or aluminum alloy. It is the installation base of the valve mechanism and the sealing cover of the cylinder. It forms the combustion chamber with the cylinder and the top of the piston. Due to the complicated structure of the cylinder head, its processing is difficult to achieve through mechanical cutting. The production method is casting molding; because the temperature of the casting liquid is very high, it takes a long cooling time after casting molding. Before the cooling is completed, it is impossible to take the mold of the cylinder head and recycle the mold, which not only affects the production of the casting Efficiency also leads to an increase in the number of casting molds, w...

Problems solved by technology

[0004] At present, the general cold water tank is basically one or two simple water storage tanks. The use of one water storage tank is easy to make the warm water of the return water mix with the original cold water, so that the heat energy is reduced and the cooling effect is poor. Two tanks The use of body, the volume is too large, it is easy to cause unnecessary waste, so a water storage tank that can prevent the mixing of cold and hot water is very important;

[0005] The existing cold and hot mixed water storage tank has poor cooling efficiency and high energy consumption and high cost when cooling down
