Description

Technical Field

[0001] This utility model relates to the field of high-temperature resistant motor technology, specifically a high-temperature resistant water-cooled special motor. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy, driving mechanical motion through the principle of electromagnetic induction. It is one of the most crucial power devices in modern industry, transportation, and daily life.

[0003] Traditional bell-type furnaces typically require an external water-cooled sealing cover to ensure normal operation of their motors. This complicates the connection between the motor and the bell-type furnace, affects the furnace's sealing performance, and simply adding a water-cooled sealing cover cannot effectively dissipate heat from the motor's internal components (moving element, stator, and shaft), thus impacting the motor's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant water-cooled special motor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant water-cooled special motor, comprising a sealing cover, a mover rotatably connected inside the sealing cover, a main shaft fixedly connected to one end of the mover, stators fixedly connected to both sides inside the sealing cover, a first bent pipe fixedly connected inside both sides of the sealing cover, a coil fixedly connected to the other end of the first bent pipe, the coil sleeved on the outside of the stator, a second bent pipe fixedly connected between the other ends of the coil, a plurality of sets of sleeves sleeved on the outside of the mover, water pipes intersecting between adjacent sleeves fixedly connected, a third bent pipe and a fourth bent pipe fixedly connected to one side of the lowest and highest sleeves, the other ends of the third bent pipe and the fourth bent pipe penetrating to the outside of the sealing cover.

[0006] Preferably, an air inlet pipe is fixedly connected to one side of the sealing cover.

[0007] Preferably, the outer side of the moving part is provided with a labyrinth pattern.

[0008] Preferably, two sets of oil injection pipes are fixedly connected to one side of the sealing cover, and the inside of the oil injection pipes is directly opposite the main shaft.

[0009] Preferably, one end of the sealing cover has an integrally formed flange.

[0010] Preferably, hooks are fixedly connected to both sides of the sealing cover.

[0011] Preferably, the spindle is made of high-temperature resistant stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model achieves cooling of the stator by injecting cooling water through a first bend pipe on one side, passing through a coil on one side, entering the coil on the other side through a second bend pipe, and then exiting through a first bend pipe on the other side. Another cooling water system enters the lowest sleeve through a third bend pipe, flows sequentially into the upper sleeve through a water pipe, and then exits through a fourth bend pipe to cool the outside of the mover. The sealing cover is directly installed on the outside of the furnace body through a flange. High-temperature resistant grease is injected into the inner main shaft through an oil injection pipe. By setting up a dual-system cooling water system in conjunction with a high-temperature lubricating oil injection system, the internal mover, stator, and bearings of the motor are cooled, making it convenient to install the motor directly on the outside of the furnace body.

[0014] 2. This utility model also increases the air pressure inside the sealing cover by injecting protective gas through the air inlet pipe, and a labyrinth pattern is provided on the outside of the mover. The labyrinth pattern increases the flow distance of the water flow and prevents cold water from flowing into the motor body. Attached Figure Description

[0020] Please see Figure 1-3This utility model provides a technical solution: a high-temperature resistant water-cooled special motor, including a sealing cover 1, a mover 4 rotatably connected inside the sealing cover 1, a main shaft 3 fixedly welded to one end of the mover 4, a stator 5 fixedly welded to both sides inside the sealing cover 1, a first bend 6 fixedly welded to both sides inside the sealing cover 1, a coil 7 fixedly welded to the other end of the first bend 6, the coil 7 is sleeved on the outside of the stator 5, a second bend 8 fixedly welded between the other ends of the coil 7, a number of sets of sleeves 10 are sleeved on the outside of the mover 4, water pipes 11 are fixedly welded between adjacent sleeves 10, and a third bend 9 and a fourth bend 12 are fixedly welded to one side of the lowest and highest sleeves 10, the other ends of the third bend 9 and the fourth bend 12 penetrate to the outside of the sealing cover 1;

[0021] An air inlet pipe 13 is fixedly welded to one side of the sealing cover 1. The air inlet pipe 13 is filled with protective gas to increase the internal air pressure of the sealing cover 1 and prevent cold water from flowing into the motor body. A labyrinth pattern 14 is provided on the outside of the mover 4. The labyrinth pattern 14 increases the flow distance of the water flow and, together with the rotation of the mover 4, can prevent water from flowing in. Two sets of oil injection pipes 15 are fixedly welded to one side of the sealing cover 1. The inside of the oil injection pipes 15 is directly opposite the main shaft 3, which can directly inject high-temperature resistant grease into the inner main shaft 3 after the equipment is installed, ensuring the service life of the motor under high temperature conditions. A flange 2 is integrally formed at one end of the sealing cover 1, which can directly install the equipment onto the furnace body. Hooks 16 are fixedly welded to both sides of the sealing cover 1 for easy hoisting of the whole equipment. The main shaft 3 is made of high-temperature resistant stainless steel, making the equipment more suitable for high-temperature environments.

[0022] Working principle: In use, this utility model cools the stator 5 by injecting cooling water through the first bend pipe 6 on one side, passing through the coil 7 on one side, and then entering the coil 7 on the other side through the second bend pipe 8. The cooling water is then discharged through the first bend pipe 6 on the other side. Another cooling water system enters the lowest sleeve 10 through the third bend pipe 9, flows into the upper sleeve 10 through the water pipe 11, and is discharged through the fourth bend pipe 12 to cool the outside of the mover 4. The sealing cover 1 is directly installed on the outside of the furnace body through the flange 2. High-temperature resistant grease is injected into the inner main shaft 3 through the oil injection pipe 15 to ensure the service life of the motor under high temperature conditions. Protective gas is injected into the air inlet pipe 13 to increase the air pressure inside the sealing cover 1. The outside of the mover 4 is provided with a labyrinth pattern 14, which increases the flow distance of the water and prevents cold water from flowing into the motor body.
