Background

The most essential difference between aqueous paints, which are paints using water as a diluent, and oily paints, which use organic solvents, which are generally harmful to humans, polluting and flammable to the atmosphere and which evaporate into the air during film formation, is the choice of solvents, which is a so-called health threat. Moreover, these harmful substances do not evaporate completely in a short time, such as formaldehyde, which may take 5 to 10 years to evaporate completely. Thus, the damage of these organic solvents to the human body becomes a long-term behavior. The water-based paint replaces an organic solvent with water, so that water is volatilized during film formation, and no harm is brought to a human body. Therefore, the most essential difference between aqueous environmentally friendly paints and oily paints is their environmental friendliness and their impact on human health.

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, a water cooling system for a grinder comprises a heat exchange device and a heat dissipation device, wherein the heat exchange device comprises a heat exchange channel 6 arranged on the outer side of a rotary cylinder 1 of the grinder, the heat exchange channel 6 is of a spiral structure, the heat dissipation device comprises a heat dissipation roller 5 with a first screw rod 4, the heat dissipation roller 5 is connected with a water storage tank 2, the height of the water storage tank 2 is greater than that of the rotary cylinder 1, and the water storage tank 2 and the heat exchange channel 6 are connected to complete cooling circulation of water.

The heat exchange channel 6 is of a spiral structure, liquid water in the heat exchange channel 6 rapidly rotates along with the rotation of the rotary drum 1, heat generated when the rotary drum 1 rotates is rapidly taken away, and as the height of the water storage tank 2 is higher than that of the rotary drum 1, new cooling water is continuously supplemented into the rotary drum 1 from the water storage tank 2 in the rotating and transferring processes of the cooling water in the rotary drum 1, so that the automatic circulation of the cooling water is completed, the cooling water is prevented from being circulated by using extra power such as an independent electric pump and the like, and the structure and the operation mode are simplified; the cooling water of accomplishing the heat transfer drives first screw rod 4 rotatory in heat dissipation roller 5, both can realize by the conversion of water pressure with 4 kinetic energy of first screw rod, has aggravated the chaotic degree of cooling water again, has carried out thermal scattering and disappearing in heat dissipation roller 5 with higher speed to the cooling water, and the mill is rotatory faster, then the circulating speed of cooling water is also faster, has reduced artificial control, and smooth completion is to the control of mill heat.

In order to optimize the heat dissipation effect, a heat dissipation fin 3 for heat dissipation is arranged between the heat dissipation roller 5 and the water storage tank 2. Through setting up radiating fin 3, further prolong the radiating path of cooling water in the radiating process, guarantee the fall back of temperature, prepare for subsequent recirculation.

In order to further optimize the heat dissipation effect, the first screw 4 of the heat dissipation roller 5 is provided with a speed reduction sheet. Set up the air brake, increase the rotational resistance of first screw rod 4 in the heat dissipation roller 5, reduce water velocity, increase heat exchange efficiency.

In order to further optimize the heat dissipation effect, an S-shaped heat dissipation fin is arranged outside the heat dissipation roller 5. The radiating fins 3 are directly arranged on the outer side of the radiating roller 5, and the radiating effect can be better achieved by directly radiating through the radiating fins 3 when cooling water is used for radiating.
