Description

Technical Field

[0001] This utility model relates to the field of ore grinding technology, specifically to an ore grinding machine with adjustable nano-ceramic ball specifications. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which possess certain usable properties. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in ore is called ore grade. For precious metal ores such as gold and platinum, this is expressed in grams per ton (g / t), while for other ores, it is usually expressed as a percentage. Ore grade is commonly used to measure the value of ore, but the composition of gangue and the amount of harmful impurities in ores containing the same effective components also affect the ore's value.

[0003] In the process of ore grinding, an ore grinding mill with adjustable nano-ceramic ball specifications is required. Most existing ore grinding mills use grinding media of fixed specifications, such as steel balls and ceramic balls. When faced with ores with different hardness and particle size requirements, it is difficult to flexibly adjust the specifications of the grinding media, resulting in poor grinding effect. Therefore, an ore grinding mill with adjustable nano-ceramic ball specifications is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a ore grinding mill with adjustable nano-ceramic ball specifications, which has the advantages of high grinding efficiency and strong practicality. It solves the problem that most existing ore grinding mills use fixed-specification grinding media, such as steel balls and ceramic balls, which makes it difficult to flexibly adjust the specifications of the grinding media when facing ores with different hardness and particle size requirements, resulting in poor grinding effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ore grinding mill with adjustable nano-ceramic ball specifications, comprising a grinding chamber, a top cover detachably connected to the top of the grinding chamber, a feed inlet fixedly connected to the top of the top cover, and a discharge pipe fixedly connected to the bottom of the grinding chamber. The upper surface of the top cover is provided with an adaptive grinding mechanism extending into it, and the upper surface of the top cover is provided with a cooling mechanism extending to the outside of the grinding chamber.

[0006] The adaptive grinding mechanism includes a bushing rotatably connected to the top of the top cover and extending into it, a drive shaft fixedly connected to the inside of the bushing, a sliding sleeve slidably connected to the outside of the drive shaft, a connecting sleeve fixedly connected to the outside of the sliding sleeve, a support rod hinged to the outside of the connecting sleeve, a movable plate hinged to the end of the support rod away from the connecting sleeve, a number of nano-ceramic spheres fixedly connected to the outside of the movable plate, and a drive mechanism disposed on the top of the top cover for driving the drive shaft.

[0007] The cooling mechanism includes a pump casing fixedly connected to the top of the top cover, a coolant tank located on one side of the grinding chamber, several annular pipes fixedly installed outside the grinding chamber, a flexible hose fixedly connected between the annular pipes and the pump casing, a delivery pipe fixedly connected between the pump casing and the coolant tank, and a delivery structure located inside the pump casing and extending to its outside.

[0008] Furthermore, the drive mechanism includes a motor base fixedly connected to the top of the top cover, a dual-axis motor fixedly installed inside the motor base, a secondary bevel gear fixedly installed outside the bushing, and a main bevel gear fixedly connected to the left output shaft of the dual-axis motor.

[0009] Furthermore, the main bevel gear and the secondary bevel gear mesh with each other, and the bushing and the transmission shaft are rotatably connected to the upper surface of the top cover and extend into the interior of the grinding chamber.

[0010] Furthermore, there are three sets of support rods and movable plates. The three sets of support rods and movable plates are arranged in a ring shape outside the transmission shaft. A limiting sleeve is fixedly connected to the outside of the transmission shaft. The bottom ends of the three sets of movable plates are hinged to the outer wall of the limiting sleeve.

[0011] Furthermore, several of the nano-ceramic spheres are arranged from largest to smallest from top to bottom and abut against the inner wall of the grinding chamber.

[0012] Furthermore, a limiting seat is fixedly connected to the bottom end of the drive shaft, and a return spring is fixedly connected between the limiting sleeve and the connecting sleeve. The return spring is connected to the outside of the drive shaft.

[0013] Furthermore, the conveying structure includes a drive gear rotatably connected inside the pump housing and a driven gear rotatably connected inside the pump housing. The pump housing has a sealed working cavity that matches the drive gear and the driven gear. The drive gear and the driven gear are meshed with each other and rotate synchronously inside the sealed working cavity. The drive gear is fixedly connected to the right output shaft of the dual-shaft motor through a connecting shaft.

[0014] Furthermore, several annular tubes are distributed at equal intervals outside the grinding chamber, and a connecting pipe is fixedly connected between several annular tubes. A circulation pipe is fixedly connected between the bottom annular tube and the coolant tank.

[0015] Compared with the prior art, this utility model provides a ore grinding mill with adjustable nano-ceramic ball sizes, which has the following beneficial effects:

[0016] 1. This ore grinding mill with adjustable nano-ceramic ball specifications, when started by a dual-shaft motor, drives the main bevel gear and the secondary bevel gear to rotate, driving the bushing and transmission shaft to rotate. Under the elastic force of the return spring, the sliding sleeve slides on the transmission shaft, causing the support rod and movable plate to open or close, thereby adjusting the size of the nano-ceramic balls. Through the centrifugal force and impact force generated by the rotation, the nano-ceramic balls achieve the best grinding effect in the grinding chamber, achieving the advantage of high grinding efficiency.

[0017] 2. This ore grinder with adjustable nano-ceramic ball specifications, when started by a dual-shaft motor, drives the drive gear to rotate and mesh with the driven gear, creating a negative pressure inside the pump casing. This pressure draws coolant from the coolant tank through a delivery pipe to the pump casing. The coolant is then evenly distributed to the outer wall of the grinding chamber through an annular pipe, providing comprehensive cooling of the grinding chamber. This effectively absorbs the heat generated in the grinding chamber, reducing its temperature and ensuring the stability and quality of the grinding process, thus achieving the advantage of high practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1 to 4 This embodiment of an ore grinding mill with adjustable nano-ceramic ball specifications includes a grinding chamber 1, a top cover 2 detachably connected to the top of the grinding chamber 1, a feed inlet 3 fixedly connected to the top of the top cover 2, and a discharge pipe 25 fixedly connected to the bottom of the grinding chamber 1. The upper surface of the top cover 2 is provided with an adaptive grinding mechanism extending into it, and the upper surface of the top cover 2 is provided with a cooling mechanism extending out of the grinding chamber 1. The adaptive grinding mechanism includes a bushing 13 rotatably connected to the top of the top cover 2 and extending into it, a drive shaft 4 fixedly connected inside the bushing 13, a sliding sleeve 5 slidably connected to the outside of the drive shaft 4, a connecting sleeve 6 fixedly connected to the outside of the sliding sleeve 5, a support rod 7 hinged to the outside of the connecting sleeve 6, a movable plate 8 hinged to the end of the support rod 7 away from the connecting sleeve 6, a number of nano-ceramic ball bodies 9 fixedly connected to the outside of the movable plate 8, and a drive mechanism provided on the top of the top cover 2 for driving the drive shaft 4.

[0025] The drive mechanism includes a motor base 15 fixedly connected to the top of the top cover 2, a dual-axis motor 16 fixedly installed inside the motor base 15, a secondary bevel gear 14 fixedly installed outside the bushing 13, and a main bevel gear 17 fixedly connected to the output shaft at the left end of the dual-axis motor 16.

[0026] Specifically, the main bevel gear 17 and the secondary bevel gear 14 mesh with each other. The bushing 13 and the transmission shaft 4 are both rotatably connected to the upper surface of the top cover 2 and extend into the interior of the grinding chamber 1. There are three sets of support rods 7 and three sets of movable plates 8, which are arranged in a ring shape outside the transmission shaft 4. The transmission shaft 4 is fixedly connected to the outside of the limit sleeve 10, and the bottom ends of the three sets of movable plates 8 are hinged to the outer wall of the limit sleeve 10. When the dual-axis motor 16 is started, it drives the main bevel gear 17 and the secondary bevel gear 14 to engage in transmission, driving the bushing 13 and the transmission shaft 4 to rotate, thereby adjusting the size of the nano-ceramic spheres 9. Through the centrifugal force and impact force generated by the rotation, the nano-ceramic spheres 9 achieve the best grinding effect in the grinding chamber 1.

[0027] It should be noted that several nano-ceramic spheres 9 are arranged from largest to smallest from top to bottom, and abut against the inner wall of the grinding chamber 1. A limiting seat 12 is fixedly connected to the bottom end of the drive shaft 4. A return spring 11 is fixedly connected between the limiting sleeve 10 and the connecting sleeve 6, and the return spring 11 is wrapped around the outside of the drive shaft 4. Under the elastic force of the return spring 11, the sliding sleeve 5 slides on the drive shaft 4, causing the support rod 7 and the movable plate 8 to open or retract. Simultaneously, due to centrifugal force, the sliding sleeve 5 slides downwards along the drive shaft 4, causing the connecting sleeve 6 to move downwards as well. When the dual-axis motor 16 stops working, the rotational speed of the drive shaft 4 gradually decreases, the centrifugal force decreases, and under the elastic force of the return spring 11, the sliding sleeve 5 slides upwards along the drive shaft 4, and the connecting sleeve 6, support rod 7, and movable plate 8 reset, restoring the nano-ceramic spheres 9 to their initial state.

[0028] In this embodiment, the cooling mechanism includes a pump housing 18 fixedly connected to the top of the top cover 2, a coolant tank 22 disposed on one side of the grinding chamber 1, several annular pipes 21 fixedly installed outside the grinding chamber 1, a flexible hose 23 fixedly connected between the annular pipes 21 and the pump housing 18, a delivery pipe 24 fixedly connected between the pump housing 18 and the coolant tank 22, and a delivery structure disposed inside the pump housing 18 and extending to its outside.

[0029] The conveying structure includes a drive gear 19 rotatably connected inside the pump housing 18 and a driven gear 20 rotatably connected inside the pump housing 18. The pump housing 18 has a sealed working cavity that matches the drive gear 19 and the driven gear 20. The drive gear 19 and the driven gear 20 are meshed with each other and rotate synchronously inside the sealed working cavity. The drive gear 19 is fixedly connected to the right output shaft of the dual-shaft motor 16 through a connecting shaft.

[0030] Specifically, several annular pipes 21 are distributed at equal intervals outside the grinding chamber 1, and the annular pipes 21 are fixedly connected to each other by a connecting pipe. The bottom annular pipe 21 is fixedly connected to the coolant tank 22 by a circulation pipe.

[0031] The working principle of the above embodiments is as follows:

[0032] In operation, the ore falls from the feed inlet 3 into the grinding chamber 1. The controller activates the dual-shaft motor 16, which, through the meshing of the main bevel gear 17 and the secondary bevel gear 14, drives the bushing 13 and the transmission shaft 4 to rotate. The return spring 11 causes the sliding sleeve 5 to slide on the transmission shaft 4, opening or closing the support rod 7 and the movable plate 8, thus adjusting the size of the nano-ceramic balls 9. The nano-ceramic balls 9 contact the ore inside the grinding chamber 1, grinding it through the centrifugal force and impact generated by their rotation. The right-hand output shaft of the dual-shaft motor 16 drives the drive gear 19 to rotate via a connecting shaft, meshing synchronously with the driven gear 20. This delivers coolant from the coolant tank 22 through the conveying pipe 24 to the pump casing 18. The coolant is then evenly distributed to the outer wall of the grinding chamber 1 through the annular pipe 21, cooling the grinding chamber 1 and ensuring stable operation of the equipment in high-temperature environments. The ground ore is discharged from the grinding chamber 1 through the discharge pipe 25 and enters subsequent processing steps.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0034] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
