Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof motors, in particular to a water-cooling heat dissipation structure of an explosion-proof motor housing. Background Art

[0002] Explosion-proof motors are motors designed to prevent fire or explosion in flammable gas or dust environments. They have special explosion-proof structures and durable materials that meet explosion-proof standards to ensure safe and reliable operation of the equipment in hazardous environments. In order to dissipate heat, a cooling water pipeline system is usually arranged on the explosion-proof motor housing. The water cooling technology is used to dissipate heat and reduce the temperature of the motor during operation to ensure the safety and reliability of the equipment.

[0003] Since explosion-proof motors are usually used in complex environments, there is dust, grease or other pollutants in the operating environment. These substances can easily enter the cooling water piping system and form dirt. If the dirt enters the coolant channel inside the explosion-proof motor housing, it will reduce the flow rate of the cooling water and the heat dissipation effect, and even cause blockage, affecting the normal heat dissipation of the explosion-proof motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] 1. The utility model installs a filter tank on the water inlet pipe and arranges a filter screen in the filter tank.

[0025] See also Figure 1-Figure 4 The utility model provides a water-cooling heat dissipation structure of an explosion-proof motor housing, comprising an explosion-proof motor housing 1, a cooling liquid channel 2 is arranged in the explosion-proof motor housing 1, a water inlet pipe 3 is fixed on one side of the explosion-proof motor housing 1, a drain pipe 4 is fixed on the other side of the explosion-proof motor housing 1, a filter tank 5 is installed on the water inlet pipe 3, a filter screen 6 is arranged in the filter tank 5, an inlet pipe 52 is connected to the filter tank 5, the water inlet pipe 3 is communicated with one side of the cooling liquid channel 2, and the drain pipe 4 is communicated with the other side of the cooling liquid channel 2.

[0026] During the operation of the explosion-proof motor, the coolant flows into the cooling channel 2 through the inlet pipe 52 and the water inlet pipe 3 in turn, which can absorb the heat generated inside the explosion-proof motor housing 1 and discharge it through the drain pipe 4 to achieve water cooling. The high-temperature coolant discharged from the drain pipe 4 flows back to the coolant cooling device for cooling, and then flows into the cooling channel 2 again through the inlet pipe 52 and the water inlet pipe 3 to achieve circulating heat dissipation cooling of the coolant. Before the coolant enters the water inlet pipe 3, it will flow through the filter tank 5. The filter screen 6 arranged in the filter tank 5 can filter out dirt and impurities in the coolant to avoid entering the cooling channel 2 and reducing the flow rate and heat dissipation effect of the cooling water, which is conducive to the continuous stability of water cooling.

[0027] Specifically, one end of the filter tank 5 is connected to the water inlet pipe 3, and the other end has an opening.

A retaining ring 62 is fixed on the inner wall of the filter tank 5 close to the water inlet pipe 3. A clamping cylinder 63 that is matched and inserted into the filter tank 5 is fixed on the sealing cover 51.

The annular mounting frame 61 is limited between the retaining ring 62 and the end of the clamping cylinder 63. The coolant flows into the filter tank 5 through the inlet pipe 52, and the dirt is filtered out by the filter screen 6. The coolant flows into the cooling liquid channel 2 through the water inlet pipe 3 to achieve water-cooled heat dissipation.

[0028] Install the filter 6 into the filter tank 5, then insert the pressing cylinder 63 into the filter tank 5, and tighten the sealing cover 51. The end of the pressing cylinder 63 presses the annular mounting frame 61 onto the retaining ring 62 to achieve the limited installation of the filter 6 and the annular mounting frame 61. The threaded installation method of the sealing cover 51 makes the sealing cover 51 detachable.

[0031] Specifically, a rubber sealing ring 53 is provided in the sealing cover 51. When the sealing cover 51 is tightly covered on the filter tank 5, the rubber sealing ring 53 is tightly squeezed between the rubber sealing ring 53 and the end face of the filter tank 5 away from the water inlet pipe 3, thereby achieving a sealing effect and preventing leakage of the coolant.

[0032] Specifically, a plurality of cooling fins 11 are arranged on the outer wall of the explosion-proof motor housing 1, and the plurality of cooling fins 11 are arranged in a ring-shaped array around the axis of the explosion-proof motor housing 1.
