Description

Technical Field

[0001] This application relates to ore sample grinding technology, and more particularly to an ore sample grinding device. Background Technology

[0002] Before testing, ore samples need to be ground to different particle sizes to meet the analytical requirements of different equipment such as spectroscopy, diffraction, or chemical analysis.

[0003] Existing ore sample grinding equipment is a sealed sample preparation machine. A grinding jar contains rotating grinding blocks. Ore lumps are placed inside the jar, and a vibrating table causes the grinding blocks to crush and grind the ore. The ore lumps are gradually ground to smaller particle sizes within the jar. However, existing grinding equipment cannot discharge the material during the grinding process, making it difficult to control the particle size of the discharged material. Utility Model Content

[0004] This application provides an ore sample grinding device to solve the problem that existing ore sample grinding devices cannot control the grinding particle size in a timely manner during the grinding process.

[0005] This application provides a grinding device for ore samples, including a housing, a vibrating table installed inside the housing, a grinding jar fixed on the vibrating table, a cover closed at the top of the grinding jar by a clamping device, a discharge fan fixedly installed at the side of the housing, the discharge fan being connected to one end of the grinding jar via an air inlet pipe, the other end of the grinding jar being connected to an exhaust pipe, a mesh plate being provided at the connection between the inner wall of the grinding jar and the air inlet and exhaust pipes, a downward-facing collection tank being installed at the end of the exhaust pipe, and a detachably connected collection box being provided at the bottom of the collection tank.

[0006] Optionally, the discharge fan is equipped with an air filter for removing impurities from the air.

[0007] Optionally, the end of the exhaust pipe is connected to a vertically fixed sorting pipe, and multiple downwardly inclined branch pipes are staggered on the sorting pipe. Each branch pipe is equipped with a detachably connected collection cup. The sorting pipe is equipped with a guide plate for guiding the flow to the branch pipes. The bottom of the sorting pipe is connected to an upward-blowing sorting fan.

[0008] Optionally, the ends of the exhaust pipe and the sorting pipe are fixed with a dust discharge port for discharging impurities during cleaning, and the dust discharge port can be opened and closed by a valve.

[0009] Optionally, the guide plate is hinged to the sorting pipe, and the guide plate can rotate to a vertical position when discharging dust.

[0010] The ore sample grinding apparatus provided in this application involves simultaneously grinding the ore in a grinding jar and promptly discharging the ground ore powder through a discharge blower, ensuring uniform powder fineness. The ground ore powder is then blown into an exhaust pipe via the discharge blower and inlet pipe, and subsequently collected and stored in a collection tank. After grinding is complete, the collection box is removed to extract the ore powder. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0020] like Figures 1-5 As shown, one embodiment of this application provides a grinding device for ore samples, including a housing 1, a vibration table 2 installed inside the housing 1, a grinding jar 3 fixed on the vibration table 2, a cover 4 covering the upper end of the grinding jar 3 by a clamping device 5, a discharge fan 6 fixedly installed on the side end of the housing 1, the discharge fan 6 being connected to one end of the grinding jar 3 through an air inlet pipe 7, the other end of the grinding jar 3 being connected to an exhaust pipe 9, a mesh plate being provided at the connection between the inner wall of the grinding jar 3 and the air inlet pipe 7 and the exhaust pipe 9, and a downward-facing collection tank 10 being installed at the end of the exhaust pipe 9, with a detachably connected collection box 11 at the bottom of the collection tank 10.

[0021] In use, the ore to be ground is placed into the grinding jar 3, the cover 4 is closed and secured with the clamping device 5, and the vibrating table 2 is started to grind the ore using the grinding media inside the grinding jar 3. Simultaneously, the discharge fan 6 is started, blowing air into the grinding jar 3 through the air inlet pipe 7, and the ground ore powder is blown into the collection tank 10 through the exhaust pipe 9. After grinding is complete, the ore powder can be easily removed by removing the collection box 11 at the bottom of the collection tank 10.

[0022] In this embodiment, while the ore is being ground in the grinding tank 3, the ground ore powder is promptly discharged from the grinding tank 3 by the discharge blower 6, ensuring that the fineness of the ground ore powder is uniform. The ore powder ground in the grinding tank 3 is blown into the exhaust pipe 9 through the discharge blower 6 and the air inlet pipe 7, and then enters the collection tank 10 for collection and storage along the exhaust pipe 9. After grinding is completed, the collection box 11 is removed to take out the ore powder.

[0023] In one possible implementation, the discharge fan 6 is equipped with an air filter 8 for filtering out impurities in the air.

[0024] Air filter 8 is used to filter the air intake of discharge blower 6, making the airflow blown by discharge blower 6 into grinding tank 3 cleaner.

[0025] In one possible implementation, the end of the exhaust pipe 9 is connected to a vertically fixed sorting pipe 12, and the sorting pipe 12 is provided with a plurality of downwardly inclined branch pipes 13 interlaced. The branch pipes 13 are provided with detachably connected collection cups 14. The sorting pipe 12 is provided with a guide plate 15 for guiding the flow to the branch pipes 13. The lower part of the sorting pipe 12 is connected to an upwardly blowing sorting fan 16.

[0026] The ore powder discharged from the exhaust pipe 9 is guided upwards by the separating fan 16 and blown into the separating pipe 12. The air force and speed of the separating fan 16 are controlled by a knob to vertically separate the ore powder in the separating pipe 12, so that ore powder of different particle sizes enters the collection cups 14 of different heights from the branch pipes 13. During testing, the corresponding collection cup 14 can be directly removed for use, eliminating the need for manual sieving after grinding.

[0027] In one possible implementation, the ends of the exhaust pipe 9 and the sorting pipe 12 are fixed with a dust discharge port 17 for discharging impurities during cleaning, and the dust discharge port 17 can be opened and closed by a valve.

[0028] After grinding is complete, open the discharge port 17 at the end of the exhaust pipe 9 and the sorting pipe 12, and turn the discharge fan 6 and the sorting fan 16 to their maximum to clean the inner walls of the grinding tank 3, exhaust pipe 9 and sorting pipe 12. The dust blown out by the air cleaning is discharged from the discharge port 17.

[0029] In one possible implementation, the guide plate 15 is hinged to the sorting pipe 12, and the guide plate 15 can rotate to a vertical position when discharging dust.

[0030] During cleaning, rotating the guide plate 15 to a vertical position can reduce obstruction inside the sorting tube 12, ensuring that the dust inside the sorting tube 12 can be cleaned and discharged smoothly.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
