[0025] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figure 1-4 As shown, a grinding machine with a dust collection function includes a support frame 1, an air suction hood 9 is fixedly connected to the top of the support frame 1, one end of the air suction hood 9 is fixedly connected to a cooling pipe 12, one side of the cooling pipe 12 is fixedly connected to a cooling component, one end of the cooling pipe 12 is fixedly connected to a cyclone separator 19, and the air outlet end of the cyclone separator 19 is fixedly connected to a dust suction pump 14 through a pipeline;

[0029] The cooling component includes a cooling pump 20 and a vortex tube 21. The cooling pump 20 is fixedly connected to one side of the cyclone separator 19. The air outlet end of the cooling pump 20 is fixedly connected to the vortex tube 21. One end of the cold air outlet of the vortex tube 21 is fixedly connected to the inner side of the cooling pipe 12 through a pipe.

[0030] When the inner wall of a large steel pipe is being ground, it is placed on top of the support frame 1 and rotated. The suction hood 9 can be attached to one end of the large steel pipe during grinding. In this way, when the dust suction pump 14 is working, the dust generated by grinding and the flying debris can be continuously sucked into the cyclone separator 19. The cyclone separator 19 can use the internal cyclone cylinder to let the dust particles and debris be thrown toward the inner wall under the action of centrifugal force, and then lose kinetic energy and fall to the bottom of the cyclone separator 19 for centralized recovery, which can realize the separation of dust particles and debris while collecting dust, and at the same time, connect to the cooling pipe 12 through one end of the cold air outlet of the vortex tube 21;

[0031] When the cooling pump 20 pumps high-speed gas into the vortex tube 21, the centrifugal force separates the gas into an inner layer and an outer layer. The inner layer of the airflow loses energy and its temperature drops, forming a cold airflow; the outer layer of the airflow gains momentum, its kinetic energy increases, and rubs against the vortex tube wall, converting part of its kinetic energy into heat energy, forming a hot airflow. These two airflows are respectively drawn out from both ends of the vortex tube 21, achieving the separation of the cold and hot airflows. The temperature at one end of the cold air outlet is around zero degrees. The low-temperature gas mixes with the high-temperature smoke and dust debris in the cooling tube 12 to cool down, preventing other components such as the cyclone separator 19 from being damaged.

[0032] In this embodiment, one side of the support frame 1 is rotatably connected to two sets of rotating drive wheel groups 2, and one side of the support frame 1 is fixedly connected to a rotating motor 3. The power output end of the rotating motor 3 is fixedly connected to the main shaft of the rotating drive wheel group 2 on one side. There are multiple driving wheels on the rotating drive wheel group 2, which can support large steel pipes on both sides. When the rotating motor 3 is started, the steel pipe can be stably rotated by driving the rotating drive wheel group 2 on one side to rotate.

[0033] In this embodiment, one end of the support frame 1 is fixedly connected to an electric screw 4, one side of the support frame 1 is slidably connected to an adjustment bracket 5, the bottom of the adjustment bracket 5 is fixedly connected to a screw nut, and one end of the screw nut is threadedly connected to the movable end of the electric screw 4;

[0034] The top of the adjustment bracket 5 is fixedly connected to a grinding motor 7, the bottom of the grinding motor 7 is fixedly connected to a grinding bracket 6, the power output end of the grinding motor 7 is fixedly connected to a drive shaft 8, one end of the grinding bracket 6 is fixedly connected to a transmission assembly 10, the power input end of the transmission assembly 10 is fixedly connected to the drive shaft 8, and the power output end of the transmission assembly 10 is fixedly connected to a grinding wheel 11, which is a grinding wheel;

[0035] During grinding, the inner wall of the steel pipe is ground by the high-speed rotation of the grinding wheel 11. When the transmission component 10 can be used for power transmission in the form of chain drive or belt drive, the high-speed rotating drive shaft 8 drives the grinding wheel 11 to grind, and the electric screw 4 is used to rotate and drive the adjustment bracket 5 at one end to move back and forth to adjust the grinding position, and the inner wall of the steel pipe is fully ground in conjunction with the continuously rotating steel pipe.

[0036] In this embodiment, a stabilizing bracket 16 is fixedly connected to the top of the support frame 1, one end of the stabilizing bracket 16 is fixedly connected to the air suction hood 9, and the inner side of the stabilizing bracket 16 is slidably connected to the polishing bracket 6. The stabilizing bracket 16 can support the air suction hood 9 and one end of the polishing bracket 6 to prevent the polishing bracket 6 from bending due to weight when moving back and forth.

[0037] In this embodiment: a large steel pipe is placed on top of the support frame 1 and rotated when the inner wall is being ground, and the suction hood 9 can be attached to one end of the large steel pipe during grinding, so that when the dust suction pump 14 is working, the dust generated by grinding and the flying debris can be continuously sucked into the cyclone separator 19, and the cyclone separator 19 can use the internal cyclone cylinder to let the dust particles and debris be thrown toward the inner wall under the action of centrifugal force, and then lose kinetic energy and fall to the bottom of the cyclone separator 19 for centralized recovery, which can realize the separation of dust particles and debris while collecting dust, and at the same time, connect to the cooling pipe 12 through one end of the cold air outlet of the vortex tube 21;

[0038] When the cooling pump 20 pumps high-speed gas into the vortex tube 21, the gas is separated into an inner layer and an outer layer due to the centrifugal force. The inner layer airflow loses energy, the temperature drops, and a cold airflow is formed; the outer layer airflow gains momentum, the kinetic energy increases, and rubs with the vortex tube wall, converting part of the kinetic energy into heat energy, forming a hot airflow. These two airflows are respectively drawn out from both ends of the vortex tube 21, realizing the separation of cold and hot airflows. The temperature at one end of the cold air outlet is around zero degrees. The low-temperature gas is mixed with the high-temperature smoke and dust debris in the cooling tube 12 to cool down, preventing other components such as the cyclone separator 19;

[0039] There are multiple driving wheels on the rotating driving wheel group 2, which can support large steel pipes on both sides. When the rotating motor 3 is started, the rotating driving wheel group 2 on one side can be driven to rotate to make the steel pipe rotate stably. During grinding, the inner wall of the steel pipe is grinded by the high-speed rotation of the grinding wheel 11. When the transmission component 10 can be powered by a chain drive or a belt drive, the grinding wheel 11 is driven by the high-speed rotating drive shaft 8 for grinding, and the electric screw 4 is used to rotate and drive the adjustment bracket 5 at one end to move back and forth to adjust the grinding position, and the inner wall of the steel pipe is fully ground in conjunction with the continuously rotating steel pipe.

[0043] The water supply pump 18 can spray water to the contact area between the grinding wheel 11 and the inner wall of the steel pipe through the water spray pipe 17 to reduce dust and cool down the steel pipe to prevent overheating.

[0044] In this embodiment, the air inlet end of the vacuum pump 14 is fixedly connected to a filter box 13, and a replaceable filter element 15 is fixedly connected to the inside of the filter box 13. The filter box 13 can further remove dust through the internal replaceable filter element 15, and the replaceable filter element 15 can be regularly disassembled and replaced to prevent blockage.
