[0002] A single-shaft crusher, also known as a single-shaft shredder or fine crusher, tears, shears, and compresses materials within its crushing chamber, breaking them into small particles. High-power crushers generate a large amount of heat during operation.

[0003] Chinese patent CN223027399U discloses a crusher with good heat dissipation, relating to the field of crusher technology. This patent, through the design of a water tank, water pump, heat dissipation sleeve, cooling pipe, connecting pipe, water conveying plate, atomizing nozzle, and L-shaped plate, allows water to be quickly drawn from the water tank and transported to the inside of the cooling pipe during pump startup. This not only rapidly cools the motor through heat conduction but also allows water to be injected into the inside of the water conveying plate through the cooling pipe, where it is atomized and sprayed out by the atomizing nozzle. This not only prevents dust but also dissipates heat from crushing rollers A and B, improving their service life.

[0004] In actual use, the temperature at the connection between the crushing structure and the motor of the aforementioned crusher is too high, affecting long-term operation; therefore, it does not meet the current requirements. In response, we have proposed a high-power single-shaft crusher. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the issue of excessive temperature at the connection between the crushing structure and the motor in existing crushers during actual use, which affects long-term operation, please refer to [the relevant documentation / reference]. Figure 1 - Figure 6 This embodiment provides the following technical solution:

[0024] This embodiment of a high-power single-shaft crusher includes a crusher housing 1, a crushing roller 2 installed inside the crusher housing 1, motors 3 installed on both sides of the crushing roller 2, and connecting shafts 202 provided at both ends of the crushing roller 2. Cooling liquid heat exchange rings 4 are installed between the two motors 3 and the crushing roller 2, and a heat exchanger 5 is installed on one side of the motor 3. A liquid guide pipe 401 and a return pipe 402 are connected between the heat exchanger 5 and the cooling liquid heat exchange ring 4.

[0025] The crushing roller 2 has an integrally formed connecting shaft 202 at both ends. The connecting shaft 202 is surrounded by six heat dissipation paddles 203. The outer surface of the heat dissipation paddles 203 is provided with an integrally formed fin air guide port 204.

[0026] In fact, the coolant heat exchange ring 4 is embedded in the part where the crushing roller 2 is connected to the speed controller 302 and is rotatably connected to the end of the connecting shaft 202 through a bearing, and the inner surface of the coolant heat exchange ring 4 is provided with a heat absorption ring 404.

[0027] In addition, both ends of the crushing roller 2 are provided with an integrally formed connecting shaft 202. The connecting shaft 202 is surrounded by six heat dissipation paddles 203. The outer surface of the heat dissipation paddles 203 is provided with an integrally formed fin air guide port 204.

[0028] It should be noted that the inside of the coolant heat exchange ring 4 is surrounded by a coolant circulation pipe 403. The two ends of the coolant circulation pipe 403 are connected to the liquid guide pipe 401 and the return pipe 402 respectively. Both the liquid guide pipe 401 and the return pipe 402 are connected to the heat exchanger 5. A water pump 501 is installed on one side of the heat exchanger 5. The inlet of the water pump 501 is connected to the coolant tank.

[0029] Specifically, the crusher uses dual motors 3 to synchronously drive the crushing roller 2 for crushing operations. During the process of the motors 3 and speed controller 302 driving the crushing roller 2, the heat dissipation paddles 203 at both ends of the crushing roller 2 rotate simultaneously. The finned air inlets 204 inside the heat dissipation paddles 203 generate airflow, which quickly removes the heat around the connecting shaft 202, allowing the hot air at both ends of the crushing roller 2 to be discharged. The coolant is then introduced by the water pump 501 through the heat exchanger 5, and then through the coolant circulation pipe 403 inside the coolant heat exchange ring 4. The coolant circulation pipe 403, together with the heat absorption ring 404, cools the connecting parts. The heat dissipation paddles 203 ensure efficient heat transfer. The finned air inlets 204 are designed with reasonable air ducts, allowing the airflow generated by the air cooling to flow smoothly through the heat exchanger 5 and other heat-generating components inside the equipment, further improving the heat dissipation effect.

[0030] In this embodiment, a feed hopper 101 is provided at the upper end of the crusher shell 1, and motor heat sinks 102 are connected to both sides of the crusher shell 1 by fixing screws. The material to be crushed is introduced into the crusher shell 1 through the feed hopper 101, and the heat generated by the motor 3 is ventilated through the motor heat sink 102.

[0031] Both ends of the crushing roller 2 are provided with retaining rings 201. The retaining rings 201 are rotatably connected to the crusher housing 1 and the motor heat sink 102 through bearings. The surface of the crushing roller 2 is provided with moving blades. During the crushing operation, the retaining rings 201 prevent the crushed debris from entering the transmission structure and causing damage.

[0032] In addition, a connecting frame 301 is installed on the outer side of the motor 3. A speed regulator 302 is fixedly connected to the outside of the connecting frame 301. The speed regulator 302 is connected to the motor 3 through the transmission wheel 303. A coupling 304 is fixedly connected between the speed regulator 302 and the connecting shaft 202. During operation, the motor 3 drives the transmission wheel 303 and the belt to drive the speed regulator 302 to rotate. The speed regulator 302 drives the connecting shaft 202 and the crushing roller 2 to rotate. The moving blades on the surface of the crushing roller 2 and the fixed blades inside the crusher housing 1 perform shearing and crushing work on the material.

[0033] Specifically, during use, the motor 3 drives the transmission wheel 303 and the belt to drive the speed regulator 302 to rotate. The speed regulator 302 drives the connecting shaft 202 and the crushing roller 2 to rotate. The retaining ring 201 prevents crushed debris from entering the transmission structure and causing damage. The moving blades on the surface of the crushing roller 2 and the fixed blades inside the crusher housing 1 shear and crush the material. The heat generated by the motor 3 is ventilated through the motor heat sink 102.

[0034] Working principle: During operation, the motor 3 drives the transmission wheel 303 and the belt to rotate the speed regulator 302. The speed regulator 302 drives the connecting shaft 202 and the crushing roller 2 to rotate. The retaining ring 201 prevents crushed debris from entering the transmission structure and causing damage. The moving blades on the surface of the crushing roller 2 and the fixed blades inside the crusher housing 1 shear and crush the material. The heat generated by the motor 3 is ventilated through the motor heat sink 102. The crushing roller 2 is driven synchronously by two motors 3. During the process of the motor 3 driving the crushing roller 2 through the speed regulator 302, the heat sinks 203 at both ends of the crushing roller 2 rotate simultaneously. The finned air vents 204 inside the heat dissipation paddle 203 generate airflow, which quickly removes the heat around the connecting shaft 202, allowing the hot air at both ends of the crushing roller 2 to be discharged. The hot air is then introduced into the heat exchanger 5 by the water pump 501 and then into the coolant circulation pipe 403 inside the heat exchanger ring 4. The coolant circulation pipe 403, in conjunction with the heat absorption ring 404, cools the connecting parts. The heat dissipation paddle 203 ensures efficient heat transfer. The finned air vents 204 are designed with reasonable air ducts, allowing the airflow generated by the air cooling to flow smoothly through the heat exchanger 5 and other heat-generating components inside the equipment, further improving the heat dissipation effect.
