DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1

[0030] like Figures 1 to 7 As shown, a direct-drive grinder described in an embodiment of the present invention includes a machine table 1, a driving motor 2 is provided on one side of the machine table 1, a feeding bin 4 is provided on one side of the driving motor 2, and an object to be ground is placed in the feeding bin 4, a grinding barrel 5 is provided on one side of the machine table 1 located at the feeding bin 4, a grinding piece 37 for grinding the object to be ground is provided in the grinding barrel 5, a main shaft 36 is provided on one side of the driving motor 2, the main shaft 36 of the driving motor 2 penetrates the feeding bin 4 and extends into the grinding barrel 5, the driving motor 2 rotates the grinding piece 37 through the main shaft 36, a discharge port 8 is provided on one side of the grinding barrel 5, a dust collector 9 is provided on one side of the grinding barrel 5, a dust removal pipe 10 is fixedly connected to one side of the dust collector 9, a plurality of filter pipes 11 are fixedly connected to one side of the dust removal pipe 10, a dust suction device is provided in each of the plurality of filter pipes 11, and the dust suction device is used to remove dust in the grinding barrel 5.

[0031] Specifically, when the current grinder grinds ore and waits for the grinding material, the grinding material is placed in the grinding barrel 5, and the driving device drives the grinding member 37 to rotate through the main shaft 36 to grind the grinding material in the grinding barrel 5. After the grinding material is ground and crushed, dust will be generated and float in the grinding barrel 5. When the ground powder particles are discharged from the grinding barrel 5 for collection and use, these powders will also be discharged from the grinding barrel 5, resulting in the problem that the working environment of the staff is full of dust, causing damage to the staff and posing a safety hazard. At the same time, the driving component drives the grinding member 37 to rotate and grind through the main shaft 36, which will cause the main shaft 36 in the grinding barrel 5 to generate static electricity, so that the dust is adsorbed on the main shaft 36, which increases the burden on the rotation of the main shaft 36, affecting the efficiency of the grinder in grinding ore and other grinding materials;

[0032] When the grinder is grinding ore or other grinding materials, the drive motor 2 is started to deliver the grinding media such as zirconia beads and the material to be ground in the feed bin 4 to the grinding barrel 5, and then the drive motor 2 is started to rotate the main shaft 36 and the grinding member 37. The rotation of the grinding member 37 causes the zirconia beads and the material to be ground to move relative to each other in the grinding barrel 5, so that the material to be ground is effectively dispersed and ground into the required particle size. At this time, the dust collector 9 and the dust suction device are started to suck the dust in the grinding barrel 5 through the dust removal pipe 10 and the filter pipe 11 into the dust collector 9 for collection and utilization. The dust generated in the grinding barrel 5 can be quickly sucked out and collected through the shunt of the dust removal pipe 10 and the filter pipe 11, so as to prevent the dust in the grinding barrel 5 from continuously floating in the grinding barrel 5. When the ground powder particles are discharged from the grinding barrel 5 through the discharge port 8 for collection and use, the situation in which the dust is discharged from the grinding barrel 5 and the working environment is filled with dust is reduced, the damage caused to the staff by the dust is reduced, the safety hazard is reduced, and the dust adsorption on the main shaft 36 is reduced to increase the burden on the rotation of the main shaft 36.

[0033] like Figure 7 As shown, the drive motor 2 is a permanent magnet motor, and the drive mode of the drive motor 2 is direct drive.

[0034] Specifically, a permanent magnet motor is used as the driving motor 2 to improve the energy efficiency ratio of the grinder and reduce the energy consumption of the grinder. The driving motor 2 is used to drive the grinder for grinding in a direct-drive manner, which greatly improves the transmission efficiency of the driving motor 2. Compared with the traditional motor position, the center of gravity is moved downward, making the grinder run more stably and reliably, and making the overall structure of the grinder equipment more compact, which is convenient for equipment installation and maintenance.

[0035] like Figure 2 As shown, a refrigerator 3 is provided on one side of the grinding barrel 5 , a cooling pipe 13 is provided on one side of the cooling machine 3 , and a plurality of shunt pipes 7 are provided on one side of the grinding barrel 5 , and the refrigeration pipe 13 is fixedly connected to the shunt pipe 7 .

[0036] Specifically, when the grinder is grinding, the refrigerator 3 is started, and the refrigerator 3 passes cold air into the grinding barrel 5 through the refrigeration pipe 13 and the diversion pipe 7, so that the cold air can better fill the grinding barrel 5 to cool it down, and the dust collector 9 sucks away the dusty air in the grinding barrel 5, so that the cold air circulates in the grinding barrel 5 to continuously cool the grinding barrel 5.

[0037] like Figure 4 As shown, the dust collecting device includes a first motor 19 fixedly connected in the filter tube 11 , a fan blade 20 is fixedly connected to the output end of the first motor 19 , and a filter screen 15 is slidably connected in the filter tube 11 .

[0038] Specifically, the first motor 19 is started to rotate the fan blades 20 to suck the dust in the grinding barrel 5 into the filter tube 11 through the filter screen 15 to prevent large particles of grinding material from being sucked into the filter tube 11, and then the dust removal pipe 10 sends the dust to the dust collector 9 for dust reduction and collection.

[0039] like Figure 5 As shown, a dust removal box 14 is fixedly connected to one side of multiple filter tubes 11, and an anti-blocking device is provided in each of the multiple dust removal boxes 14. The anti-blocking device is used to prevent the filter screen 15 from being blocked. The anti-blocking device includes a rotating wheel 29 rotatably connected to the dust removal box 14, one side of the rotating wheel 29 is fixedly connected to one end of a spring plate 30, and the other end of the spring plate 30 is fixedly connected to a steel ball 31, and a block 35 is slidably connected to one side of the rotating wheel 29 in the dust removal box 14.

[0040] Specifically, when the grinder is grinding, large particles in the grinding barrel 5 will fly and get stuck on the mesh of the filter 15, or dust will accumulate on the filter 15 after long-term use and block the filter 15, which will affect the dust from passing through the filter 15 to be discharged from the grinding barrel 5. By rotating the rotating wheel 29, the spring piece 30 rotates with the steel ball 31, and the steel ball 31 is blocked by the block 35 and cannot rotate temporarily, and the spring piece 30 is bent to generate elastic force. As the bending degree of the spring piece 30 increases, the elastic force of the spring piece 30 gradually increases, and the spring piece 30 will move the steel ball 31 upward to break away from the obstruction of the block 35. The spring piece 30 restores its deformation to make the steel ball 31 quickly hit the filter 15, thereby removing the large particles of grinding and accumulated dust stuck on the filter 15, so that the filter 15 can better filter the dust.

[0041] like Figure 6 As shown, a worm 25 is rotatably connected to one side of the dust removal box 14, a worm wheel 26 is rotatably connected to one side of the worm 25 in the dust removal box 14, a transmission rod 27 is rotatably connected in the dust removal box 14, the worm wheel 26 is fixedly connected to the transmission rod 27, the transmission rod 27 is rotatably connected to the rotating wheel 29, one side of the rotating wheel 29 is fixedly connected to one end of a spiral spring 28, and the other end of the spiral spring 28 is fixedly connected to the transmission rod 27.

[0042] Specifically, rotating the worm 25 causes the worm wheel 26 to rotate with the transmission rod 27, and the transmission rod 27 rotates with the volute spring 28, causing the volute spring 28 to deform and generate elastic force. When the volute spring 28 reaches a critical value and no longer deforms, the volute spring 28 will rotate with the rotating wheel 29 to deform the spring sheet 30. When the steel ball 31 breaks away from the obstruction of the block 35, the volute spring 28 will restore the deformation together with the spring sheet 30, causing the steel ball 31 to hit the filter screen 15 faster, thereby better removing the large-particle grinding materials and accumulated dust stuck on the column on the filter screen 15, so that the filter screen 15 can better filter the dust.

[0043] like Figure 6 As shown, a drive ring 21 is fixedly connected to one side of the fan blade 20, a transmission wheel 23 is rotatably connected in the dust removal box 14, a driven wheel 24 is fixedly connected to one side of the worm 25, and the drive ring 21, the transmission wheel 23 and the driven wheel 24 are connected through a transmission belt 22.

[0044] Specifically, the rotation of the fan blades 20 causes the drive ring 21 to rotate the driven wheel 24 through the transmission belt 22. The fixed position of the transmission wheel 23 prevents the transmission belt 22 from blocking the rotation of the steel ball 31. The rotation of the driven wheel 24 drives the worm 25 to rotate so that the anti-blocking device can remove large particles of grinding and accumulated dust on the filter screen 15.

[0045] like Figure 6 As shown, a fixed column 32 is fixedly connected to one side of the block 35 in the dust removal box 14, and the fixed column 32 is slidably connected to the block 35. A second spring 33 is sleeved on one side of the fixed column 32, and one end of the second spring 33 is fixedly connected to the dust removal box 14, and the other end of the second spring 33 is fixedly connected to the block 35.

[0046] Specifically, when the block 35 blocks the steel ball 31, the steel ball 31 will move with the block 35, and the block 35 will slide on the fixed column 32 to stretch the second spring 33. The block 35 will continue to block the steel ball 31 to deform the spring sheet 30, so that the spring sheet 30 can generate a greater elastic force to drive the steel ball 31 to hit the filter screen 15.

[0047] like Figure 6 As shown, one side of the clamping block 35 is fixedly connected to the limiting block 34 , and the dust removal box 14 is provided with a limiting groove on one side of the clamping block 35 , and the limiting block 34 is slidably connected to the limiting groove on one side of the dust removal box 14 .

[0048] Specifically, by sliding the limiting block 34 in the limiting groove of the dust removal box 14 , the clamping block 35 can slide in the dust removal box 14 without sliding out of the dust removal box 14 , thereby limiting the sliding of the clamping block 35 .

[0049] Embodiment 2

[0050] like Figure 5 As shown in Comparative Example 1, another embodiment of the present invention is:

[0051] A plurality of sliders 18 are fixedly connected to one side of the filter screen 15, and the plurality of sliders 18 are slidably connected to the filter tube 11. A plurality of fixed rods 16 are fixedly connected to the inner wall of the filter tube 11, and the plurality of sliders 18 are slidably connected to the fixed rods 16. A first spring 17 is slidably connected to one side of the plurality of fixed rods 16, and one end of the plurality of first springs 17 is fixedly connected to the filter tube 11, and the other end of the plurality of first springs 17 is fixedly connected to the slider 18.

[0052] Specifically, when the steel ball 31 hits the filter 15, the filter 15 will slide on the fixed rod 16 through the slider 18 to compress the first spring 17, so that the filter 15 slides in the filter tube 11, so that the large particles of grinding and accumulated dust on the filter 15 can be more completely separated from the filter 15, and the filter 15 can be prevented from being greatly deformed when being hit, thereby increasing the service life of the filter 15.

[0053] Working principle: When the grinder is grinding ore or other grinding materials, the drive motor 2 is started to send the grinding materials in the feed bin 4 to the grinding barrel 5, and then the drive motor 2 drives the grinding member 37 to rotate to grind the grinding materials in the grinding barrel 5. At this time, the dust collector 9 and the dust suction device are started to suck the dust in the grinding barrel 5 through the dust removal pipe 10 and the filter pipe 11 into the dust collector 9 for collection and utilization. The dust generated in the grinding barrel 5 can be quickly sucked out and collected through the shunt of the dust removal pipe 10 and the filter pipe 11; the permanent magnet motor is used as the drive motor 2 to improve the energy efficiency ratio of the grinder and reduce The energy consumption of the grinder is reduced by using a drive motor 2 that drives the grinder for grinding in a direct-drive manner, which greatly improves the transmission efficiency of the drive motor 2. Compared with the traditional motor position, the center of gravity is lowered, making the operation of the grinder more stable and reliable, and making the overall structure of the grinder equipment more compact, which is convenient for equipment installation and maintenance; the refrigerator 3 is started to pass cold air into the grinding barrel 5 through the refrigeration pipe 13 and the shunt pipe 7, so that the cold air can better fill the grinding barrel 5 to cool it down, and the dust collector 9 sucks away the dust and air in the grinding barrel 5, so that the cold air circulates in the grinding barrel 5 to continuously cool the grinding barrel 5;

[0054] The first motor 19 is started to rotate the fan blades 20 to suck the dust in the grinding barrel 5 into the filter tube 11 through the filter 15 to prevent large particles of ground material from being sucked into the filter tube 11, and then the dust removal tube 10 sends the dust to the dust collector 9 for dust reduction and collection; when the grinder is grinding, the large particles in the grinding barrel 5 will fly and get stuck on the mesh of the filter 15, or after long-term use, the dust will accumulate on the filter 15 and block the filter 15, which will affect the dust from passing through the filter 15 to be discharged from the grinding barrel 5, and the spring piece 30 is rotated with the steel ball 31 by rotating the rotating wheel 29, and the steel ball 31 will be blocked by the block 35 and cannot rotate temporarily, and the spring piece 30 is bent to generate elastic force, and as the bending degree of the spring piece 30 continues to increase, the elastic force of the spring piece 30 gradually increases, and the spring piece 30 will move the steel ball 31 upward to break away from the block 35, the spring sheet 30 recovers its deformation so that the steel ball 31 quickly hits the filter screen 15, removes the large-particle grinding and accumulated dust on the filter screen 15, so that the filter screen 15 can better filter the dust; the worm 25 is rotated to make the worm wheel 26 rotate with the transmission rod 27, and the transmission rod 27 rotates with the volute spring 28 to deform the volute spring 28 to generate elastic force, when the volute spring 28 reaches a critical value and no longer deforms, the volute spring 28 will rotate with the rotating wheel 29 to deform the spring sheet 30, when the steel ball 31 is free from the obstruction of the block 35, the volute spring 28 will recover its deformation together with the spring sheet 30 to make the steel ball 31 hit the filter screen 15 faster, better remove the large-particle grinding and accumulated dust on the filter screen 15, so that the filter screen 15 can better filter the dust;

[0055] The rotation of the fan blade 20 causes the driving ring 21 to rotate the driven wheel 24 through the transmission belt 22. The fixed position of the transmission wheel 23 prevents the transmission belt 22 from blocking the rotation of the steel ball 31. The rotation of the driven wheel 24 drives the worm 25 to rotate so that the anti-blocking device can remove large particles of grinding and accumulated dust on the filter screen 15. When the block 35 blocks the steel ball 31, the steel ball 31 will move with the block 35. The block 35 slides on the fixed column 32 to stretch the second spring 33. The block 35 will continue to block the steel ball 31 to deform the spring sheet 30, so that the spring sheet 30 can generate a greater elastic force to drive the steel ball 31 to hit the filter screen 15. The steel ball 31 hits the filter 15, and the limit block 34 slides in the limit groove of the dust box 14, so that the block 35 can slide in the dust box 14 without sliding out of the dust box 14, thereby limiting the sliding of the block 35; when the steel ball 31 hits the filter 15, the filter 15 slides on the fixing rod 16 through the slider 18 to compress the first spring 17, so that the filter 15 slides in the filter tube 11, so that the large particles of ground objects and accumulated dust on the filter 15 can be more completely separated from the filter 15, and the filter 15 can be prevented from being greatly deformed when being hit, thereby increasing the service life of the filter 15.
