Description

Technical Field

[0001] The utility model relates to a grinding machine, in particular to a dynamic separation grinding machine. Background Art

[0002] In grinding equipment, in order to meet the requirement of high fineness of grinding slurry, the separation method of grinding medium and slurry in grinding equipment is no longer limited to static separation. The centrifugal principle can be adopted, that is, the dynamic separation method is used to screen the grinding medium and slurry. The traditional dynamic centrifugal separation method is that the main motor drives the grinding rotor to rotate to provide grinding energy for the grinding medium, and the separation motor drives the separator to rotate to provide centrifugal force for the separator to separate the grinding medium and slurry. Generally, the separator is coaxially distributed with the grinding rotor and is built in the grinding rotor, running concentrically and in the same direction but at different speeds with the grinding rotor. However, if a separator without a screen structure is adopted in this dynamic separation method, zirconium beads are likely to leak. If a separator with a screen is adopted, it is easy to block the material, and both dynamic separators have the problem of small flow rate. Therefore, there is an urgent need for a grinding machine that can better achieve dynamic separation and discharging. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dynamic separation grinding machine to solve one or more technical problems in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A dynamic separation grinding machine includes: a grinding tank, inside which there is a grinding chamber and a discharging chamber that are interconnected, the discharging chamber is located above the grinding chamber, and the grinding tank is provided with a feeding port communicating with the grinding chamber; a grinding device having a grinding rotor that can rotate in the grinding chamber, and the rotation axis of the grinding rotor extends horizontally; a separator disposed in the discharging chamber, the separator has a discharging channel extending horizontally, and a plurality of separators are arranged around the discharging chamber.

[0006] The technical solution has at least the following beneficial effects: A grinding chamber for grinding materials and a discharge chamber for discharging materials are provided in the grinding tank. During use, the grinding rotor in the grinding device rotates to grind the materials in the grinding chamber. Since the separator is located above the grinding chamber, it can effectively reduce the entry of unground materials and grinding media into the separator. With the continuous grinding of the materials and the pressurization in the grinding tank, the lighter materials after grinding move upward into the separator, and the separator further screens the materials, throwing the grinding media mixed in the materials back into the grinding tank. The screened materials are then discharged and collected outward through the discharge channel or sent to the next working station. In this way, it can effectively reduce the entry of grinding media into the separator, reduce the accumulation of grinding media in the separator, and prevent the leakage of grinding media, improve the separation efficiency of the grinding media and the materials. Moreover, multiple separators can be arranged around the discharge chamber, which can increase the discharge flow rate, promote the rapid passage of materials, especially in the cyclic grinding of materials, it can increase the number of grinding passes per unit time, thereby improving the grinding efficiency.

[0007] As a further improvement of the above technical solution, the cross-section of the grinding chamber is circular, the discharge chamber extends upward on one side of the grinding chamber, and the extending direction of the discharge chamber is opposite to the rotation direction of the grinding rotor. The grinding rotor rotates in the grinding chamber, driving the materials to rotate around the grinding rotor in the grinding chamber. Since the discharge chamber extends tangentially on one side of the grinding chamber and its extending direction is opposite to the rotation direction of the grinding rotor, under the action of high-speed centrifugal force, a large amount of grinding media continues to move in a circular motion, and a small amount will hit the side wall of the grinding chamber and splash to the separator of the discharge chamber. Even when some grinding media hit the side wall of the grinding chamber and splash upward, under the action of gravity, the grinding media will also fall downward. In this way, the separation of the materials and the grinding rotor can be realized, and the separation efficiency can be improved.

[0008] As a further improvement of the above technical solution, the grinding tank includes a grinding cylinder and a discharge cylinder connected to the top side of the grinding cylinder. The grinding cylinder extends horizontally, the grinding chamber is formed in the grinding cylinder, the discharge cylinder extends vertically, the discharge chamber is formed in the discharge cylinder, and the separator is arranged around the discharge cylinder. The discharge cylinder protrudes upward on the grinding cylinder. When arranging the separator, the separator can be directly arranged around the discharge cylinder, and the outer wall of the grinding cylinder can also be used to support the separator, improving the rationality of the overall structure layout.

[0009] As a further improvement of the above technical solution, a first end cover is detachably connected to the top end of the discharge cylinder. During installation and maintenance, the discharge chamber can be opened or closed by installing and removing the first end cover, making it more convenient to use.

[0010] As a further improvement of the above technical solution, one end of the grinding cylinder is detachably connected with a second end cover. During installation and maintenance, the grinding chamber can be opened or closed by assembling and disassembling the second end cover, which is more convenient to use.

[0011] As a further improvement of the above technical solution, the utility model further includes a discharge tank. A plurality of the discharge channels are respectively connected with discharge pipes, and one ends of the plurality of discharge pipes away from the discharge channels are respectively communicated with the discharge tank. The plurality of separators can respectively convey the separated materials to the discharge tank through the discharge pipes, and the discharge tank is used for collection, transfer and temporary storage or confluence.

[0012] As a further improvement of the above technical solution, a cyclone separator is arranged in the discharge tank. The cyclone separator in the discharge tank can further screen the materials flowing into the discharge tank, so as to further improve the separation efficiency and the fineness of the slurry.

[0013] As a further improvement of the above technical solution, a feed pipe is connected to the outside of the discharge tank. The feed pipe extends along the tangential direction of the discharge tank, and a plurality of the feed pipes are arranged around the discharge tank. The plurality of discharge pipes are respectively communicated with the plurality of feed pipes. When the materials enter the discharge tank through the guidance of the feed pipe, due to the fact that the feed pipe extends along the tangential direction of the discharge tank, the materials can enter the discharge tank along the tangent of the rotation separation of the cyclone separator, so that the flow rate of the materials entering the discharge tank can be increased, and thus the separation efficiency of the materials in the discharge tank can be further improved.

[0014] As a further improvement of the above technical solution, flow sensors are respectively arranged in the plurality of discharge pipes. The discharge flow of the discharge pipes can be monitored through the flow sensors, so as to arrange different numbers of separators according to the usage requirements to meet different production capacity requirements and improve the flexibility of use.

In addition, all the connection relationships mentioned in the text do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflict.

[0022] Refer to Figures 1 to 3 , a dynamic separation grinding machine, comprising: a grinding tank 1, inside which there are a grinding chamber 11 and a discharge chamber 12 that are interconnected, the discharge chamber 12 is located above the grinding chamber 11, and the grinding tank 1 is provided with a feed port communicating with the grinding chamber 11; a grinding device 2, which has a grinding rotor 21 that can rotate in the grinding chamber 11, the rotation axis of the grinding rotor 21 extends horizontally, and of course, the grinding device 2 has a first motor, and the grinding rotor 21 is driven by the first motor to rotate; a separator 3, arranged in the discharge chamber 12, the separator 3 has a discharge channel 31 extending horizontally, and a plurality of the separators 3 are arranged around the discharge chamber 12.

[0023] In this dynamic separation grinder, a grinding chamber 11 for grinding materials and a discharge chamber 12 for discharging materials are provided in the grinding tank 1. During use, the grinding rotor 21 in the grinding device 2 rotates to grind the materials in the grinding chamber 11. Since the separator 3 is located above the grinding chamber 11, it can effectively reduce the entry of unground materials and grinding media into the separator 3. As the materials are continuously ground and the pressure in the grinding tank 1 is increased, the lighter materials after grinding enter the separator 3 upward. The separator 3 further screens the materials, throws the grinding media mixed in the materials back into the grinding tank 1, and the screened materials are discharged outwards through the discharge channel 31 for collection or sent to the next station. In this way, the entry of grinding media into the separator 3 can be effectively reduced, the accumulation of grinding media in the separator 3 leading to the leakage of grinding media can be reduced, the separation efficiency of the grinding media and the materials can be improved, and multiple separators 3 can be provided around the discharge chamber 12, which can increase the discharge flow rate, prompt the materials to pass through quickly, especially in the cyclic grinding of materials, the number of grinding passes per unit time can be increased, thereby improving the grinding efficiency.

[0024] The separator 3 mainly uses centrifugal force to throw large-particle substances outwards, while small-particle substances can be output axially. The separator 3 includes a second motor that drives a hollow shaft to rotate. A discharge channel 31 is formed inside the hollow shaft, and a separation sleeve is connected to the outside of the hollow shaft. A plurality of filter holes are provided on the separation sleeve. The separation sleeve can block the grinding media outside and, driven by the hollow shaft, throw the grinding media that crosses the filter holes outwards by centrifugal force, while small-particle substances can enter the hollow shaft and be output outwards.

[0025] The cross-section of the grinding chamber 11 can be rectangular, but in this case, the materials are likely to accumulate at the corner positions. In order to make the materials flow better along the inner side of the grinding chamber 11, in this embodiment, the shape of the cross-section of the grinding chamber 11 is circular, the discharge chamber 12 extends upwards on one side of the grinding chamber 11, and the extending direction of the discharge chamber 12 is opposite to the rotation direction of the grinding rotor 21. The grinding rotor 21 rotates in the grinding chamber 11, driving the materials to rotate around the grinding rotor 21 in the grinding chamber 11. Since the discharge chamber 12 extends tangentially on one side of the grinding chamber 11 and its extending direction is opposite to the rotation direction of the grinding rotor 21, under the action of high-speed centrifugal force, a large amount of grinding media continues to move in a circular motion, and a small amount will hit the side wall of the grinding chamber 11 and splash to the separator 3 of the discharge chamber 12. Even when some grinding media hit the side wall of the grinding chamber 11 and splash upwards, the grinding media will also fall down under the action of gravity. In this way, the separation of the materials and the grinding rotor 21 can be realized, and the separation efficiency can be improved.

[0026] As a specific structural embodiment of the grinding tank 1, the grinding tank 1 includes a grinding cylinder 13 and a discharge cylinder 14 connected to the top side of the grinding cylinder 13. The grinding cylinder 13 extends in the horizontal direction, and the grinding chamber 11 is formed inside the grinding cylinder 13. The discharge cylinder 14 extends in the vertical direction, and the discharge chamber 12 is formed inside the discharge cylinder 14. The separator 3 is disposed around the discharge cylinder 14. The discharge cylinder 14 protrudes upward from the grinding cylinder 13. When arranging the separator 3, the separator 3 can be directly arranged around the discharge cylinder 14, and the outer wall of the grinding cylinder 13 can also be used to support the separator 3, improving the rationality of the overall structural arrangement.

[0027] In some embodiments, a first end cap 15 is detachably connected to the top end of the discharge cylinder 14. During installation and maintenance, the discharge chamber 12 can be opened or closed by installing or removing the first end cap 15, making it more convenient to use.

[0028] In some embodiments, a second end cap 16 is detachably connected to one end of the grinding cylinder 13. During installation and maintenance, the grinding chamber 11 can be opened or closed by installing or removing the second end cap 16, making it more convenient to use.

[0029] The present utility model further includes a discharge tank 4. A plurality of the discharge channels 31 are respectively connected to discharge pipes 41, and one ends of the plurality of discharge pipes 41 far from the discharge channels 31 are respectively communicated with the discharge tank 4. The plurality of separators 3 can respectively convey the separated materials to the inside of the discharge tank 4 through the discharge pipes 41, and the discharge tank 4 is used for collection, transfer and temporary storage or confluence.

[0030] Furthermore, a cyclone separator 3 is arranged inside the discharge tank 4. The cyclone separator 3 is a device for separating gas-solid systems or liquid-solid systems. Its working principle is to rely on the rotational motion caused by the tangential introduction of the airflow, so that solid particles or liquid droplets with greater inertial centrifugal force are thrown to the outer wall surface and separated. At this time, the discharge tank 4 can directly serve as the housing of the cyclone separator 3. The cyclone separator 3 inside the discharge tank 4 can further screen the materials flowing into the discharge tank 4, thus further improving the separation efficiency and the fineness of the slurry.

[0031] In order to increase the speed of the material entering the discharge tank 4, in this embodiment, a feed pipe 42 is connected to the outside of the discharge tank 4. The feed pipe 42 extends along the tangential direction of the discharge tank 4, and a plurality of the feed pipes 42 are arranged around the discharge tank 4. The plurality of discharge pipes 41 are respectively communicated with the plurality of feed pipes 42. When the material enters the discharge tank 4 under the guidance of the feed pipe 42, since the feed pipe 42 extends along the tangential direction of the discharge tank 4, it can enter the discharge tank 4 along the tangent of the rotational separation of the material by the cyclone separator 3. In this way, the flow rate of the material entering the discharge tank 4 can be increased, thereby further improving the separation efficiency of the material in the discharge tank 4.

[0032] In some embodiments, flow sensors are respectively arranged in the plurality of discharge pipes 41. The discharge flow of the discharge pipe 41 can be monitored through the flow sensors, so as to arrange different numbers of separators 3 according to the usage requirements, meet different production capacity requirements, and improve the flexibility of use.

[0033] In some embodiments, a pressure sensor is arranged in the grinding chamber 11. The pressure in the grinding chamber 11 can be monitored by using the pressure sensor, so as to facilitate the adjustment of the flow rate of the material input during operation.

[0034] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
